Abstract
The utility model discloses a frock for processing thin wall tubbiness part, including the annular frock dish of circle, be equipped with a breach groove and a plurality of half breach groove on the lateral wall of frock dish, and a plurality of half breach groove and a breach groove evenly distributed on the lateral wall of frock dish, through the aforesaid setting, when the frock dish expands outward and deforms, deformation everywhere on the frock dish is comparatively even, makes the excircle of frock dish and the interior circle of work piece hug closely the locking, makes the clamping power that the work piece received even, can not produce the deformation in the clamping process; the tool disc provided by the utility model is simple and rapid to manufacture, has low material limitation, can reduce the tool cost and improve the working efficiency, and is completely suitable for batch production. On the process, the processing of the barrel-packed thin-wall part with part of the inner wall being a cone or a cambered surface can be completed through the radian adjustment of the side wall of the tool disc.
Description
Technical Field
The utility model relates to the technical field of thin-wall part machining tools, in particular to a tool for machining a thin-wall barrel-shaped part.
Background
When a thin-wall barrel-shaped part is machined, the thin-wall barrel-shaped part is an axial part and has high requirement on machining size precision, the thin-wall barrel-shaped part is directly clamped by a three-jaw chuck, the part is easy to deform, when the existing tool is matched with the part for clamping, the gap is difficult to control, the gap is too large, the part is easy to slip, the chuck cannot tightly clamp the part, the part is easy to deform, and the requirement on machining precision cannot be met. The fit clearance with the part is too small, the tool is very difficult to disassemble after the machining is finished, the part and the tool are easily damaged, unnecessary labor time of workers is consumed, the efficiency is low, and the production cost is increased to a certain extent.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a tool for machining a thin-wall barrel-shaped part.
The technical purpose of the utility model is realized by the following technical scheme:
the utility model provides a frock for processing thin wall tubbiness part, includes the annular frock dish of circle, be equipped with a breach groove and a plurality of half breach groove on the lateral wall of frock dish, and a plurality of half breach groove and a breach groove evenly distributed are on the lateral wall of frock dish, through the aforesaid setting, when the frock dish is opened outward deformation, deformation everywhere on the frock dish is comparatively even, makes the excircle of frock dish and the interior circle of work piece hug closely the locking for the clamping power that the work piece received is even, can not produce at the clamping in-process and warp.
Furthermore, one end of the tool disc is provided with a positioning shoulder, the outer diameter of the positioning shoulder is larger than the inner diameter of the workpiece, and the positioning accuracy of clamping the tool disc and the workpiece can be improved through the positioning shoulder.
Further, the number of the half-notch grooves is two.
Further, the bottom in half breach groove is equipped with the round hole, the diameter of round hole is greater than the groove width in half breach groove, through opening the round hole in half breach groove bottom, can increase the tension of processing sabot.
In conclusion, the utility model has the following beneficial effects: the tool disc provided by the utility model is simple and rapid to manufacture, has low material limitation, can reduce the tool cost and improve the working efficiency, and is completely suitable for batch production. On the process, the processing of the barrel-packed thin-wall part with part of the inner wall being a cone or a cambered surface can be completed through the radian adjustment of the side wall of the tool disc.
Drawings
FIG. 1 is an exploded view of a tooling clamp;
FIG. 2 is a perspective view of the present invention;
fig. 3 is a front view of the present invention.
In the figure, 1, a three-jaw chuck; 2. a tooling plate; 3. a workpiece; 4. a notch groove; 5. a half-notched groove; 6. a locating shoulder.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The first embodiment is as follows: as shown in fig. 2-3, a frock for processing thin wall tubbiness part, including annular frock dish 2, be equipped with a breach groove 4 and a plurality of half breach groove 5 on the lateral wall of frock dish 2, and a plurality of half breach groove 5 and a breach groove 4 evenly distributed are on the lateral wall of frock dish 2, through the aforesaid setting, when frock dish 2 is expanded outward and is deformed, deformation everywhere on the frock dish 2 is comparatively even, makes the excircle of frock dish 2 and the interior circle of work piece 3 hug closely the locking, makes the clamping power that work piece 3 received even, can not produce in the clamping in-process and warp.
Furthermore, one end of the tool disc 2 is provided with a positioning shoulder 6, the outer diameter of the positioning shoulder 6 is larger than the inner diameter of the workpiece 3, and the positioning accuracy of clamping the tool disc 2 and the workpiece 3 can be improved through the positioning shoulder 6.
Further, the number of the half-cut grooves 5 is two.
Further, the bottom of half breach groove 5 is equipped with the round hole, the diameter of round hole is greater than the groove width of half breach groove 5, through opening the round hole in half breach groove 5 bottom, can increase the tension of processing sabot 2.
Example two: as shown in fig. 2-3, a tool for machining a thin-walled barrel-shaped part includes a circular tool tray 2, a notch groove 4 and two half notch grooves 5 are provided on a side wall of the tool tray 2, and the two half notch grooves 5 and the notch groove 4 are uniformly distributed on the side wall of the tool tray 2; furthermore, one end of the tool disc 2 is provided with a positioning shoulder 6, and the outer diameter of the positioning shoulder 6 is larger than the inner diameter of the workpiece 3; further, the bottom of half breach groove 5 is equipped with the round hole, the diameter of round hole is greater than half breach groove 5's groove width.
In addition, the clamping processing of the barrel-shaped thin-walled part with a part of inner wall being a cone or a cambered surface can be completed through the radian adjustment of the side wall of the tool disc.
The working principle is as follows: as shown in fig. 1, a circular tool disc is inserted into an inner hole of a workpiece to be machined, the workpiece to be machined is positioned through a positioning shoulder, then the three-jaw chuck is adjusted to be supported inside the tool disc, the tool disc is expanded and deformed, the workpiece to be machined is clamped, and after machining is finished, when the three-jaw chuck is released from the tool disc, the tool disc is restored to the original state under the action of self elasticity, and the machined workpiece is released.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
