Description

Technical Field

[0001] The utility model relates to the technical field of tooling for machining, in particular to a pressing tooling with gap filling and supporting functions. Background Art

[0002] When machining a workpiece, it is usually placed or positioned on a fixture for fixation. When the workpiece is a shell, especially when the workpiece has a thin wall thickness, it is necessary to ensure that it is stably positioned during fine machining and that the shell is not damaged during machining; further attention should be paid to the fact that the side walls of some shells are not completely continuous, but have gaps, such as the attached Figure 5 The product 100 (partial housing of a micro-engraving machine) shown has a through gap 101 on its side wall. When machining it, it is necessary to ensure that the pressing process or the machining process will not be affected by the through gap 101.

[0003] In the prior art, there is an adjustable universal device for thin-walled special-shaped parts with application number 202222807040.X, which discloses that by adjusting the position and height of the support part and the clamping part, the reliability and stability are greatly improved while meeting the universality, and the stable positioning of thin-walled products can be achieved. However, the special-shaped parts to which it is applicable are not suitable for thin-walled products with narrow through gaps, so it is impossible to ensure the stability of the product state of such products during fixing and processing. Utility Model Content

[0004] The purpose of the utility model is to provide a pressing tool with a gap filling and supporting function. By extending the support member into the through gap on the side wall of the product to form filling and lateral support, the side wall can be prevented from being offset at the through gap after being subjected to force, thereby ensuring the stability of the pressing and the stability of the product shape, thereby ensuring the processing accuracy.

[0006] As a further optimization, the support member comprises a support plate, which is at least partially embedded in the through gap of the product.

[0007] As a further optimization, the lower end of the support plate abuts against the rotating workbench to support and position the support plate.

[0008] As a further optimization, a through hole is provided on the support plate beside the through gap of the product, and the support plate is positioned on the product by a positioning pin passing through the through hole and the product.

[0009] As a further optimization, the positioning pin is locked on the product by bolts, and the installation stability of the support plate is improved by locking.

[0010] As a further optimization, the support member also includes a limiting plate arranged at one end of the support plate and used to limit the length of the support plate protruding through the gap. The abutment between the limiting plate and the product can ensure the accurate position of the support plate.

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] like Figures 1 to 5 As shown, a pressing tool with a gap filling support function includes a rotating worktable 1, and a positioning column 2 and a clamping assembly 3 arranged on the rotating worktable 1 for fixing a product 100. The product 100 is specifically an engraving machine shell. The pressing tool also includes a support member 4, which is arranged on the rotating worktable 1 or on the product 100. The support member 4 at least partially extends into the through gap 101 of the product 100 to support the side wall of the product 100 to prevent it from being compressed and deflected.

[0024] In the present invention, during the conventional process of positioning and clamping the product 100 through the positioning column 2 and the clamping assembly 3, the support member 4 can be at least partially extended into the through gap 101, so that the side walls of the product 100 can be connected in a continuous manner with the support member 4. In particular, when the side walls of the product 100 are relatively thin, the filling of the support member 4 can avoid the formation of weak points at the through gap 101. On the one hand, it can avoid the horizontal displacement of the side walls due to the lateral processing of the side walls during the machining of the side walls of the product 100, which affects the processing accuracy. On the other hand, after the product 100 is positioned and before being clamped, the support member is embedded in the through gap 101 to avoid the displacement of the side walls due to downward pressure. Therefore, the extension of the support member 4 into the through gap 101 can avoid the displacement of the side walls at the through gap 101 after the force is applied, which can ensure the stability of the pressing and improve the processing accuracy.

[0025] More specifically, the support member 4 includes at least a support plate 41, which is at least partially embedded in the through gap 101 of the product 100. The support plate 41, which matches the width of the through gap 101, extends into the through gap 101 and abuts against both sides of the side walls of the product 100, thereby filling and supporting the side walls of the product 100.

[0026] In one embodiment of the utility model, the support plate 41 can be set to have a certain height, that is, after one side of its upper part extends into the through gap 101, its lower end can abut against the rotating workbench 1 for positioning or fixing to ensure the stability of the support plate 41.

[0027] In another embodiment of the utility model, a through hole 410 is provided on the support plate 41 next to the through gap 101 of the product 100, and the through hole 410 cooperates with the socket 102 formed on the product 100, that is, one side of the support plate 41 extends into the through gap 101, and the through hole 410 on the other side is connected with the socket 102. The support plate 41 is positioned on the product 100 by extending the positioning pin 43 into the through hole 410 and the socket 102, instead of being positioned on the rotating workbench 1, thereby improving the stability of positioning.

[0028] Furthermore, an external thread 431 is provided on one side of the positioning pin 43, and the support plate 41, the positioning pin 43, etc. are fixed to the product 100 through the locking cooperation of the bolt 44 and the external thread, thereby improving the installation stability of the support plate 41.

[0029] In addition, the support member 4 also includes a limiting plate 42 arranged at one end of the support plate 41 and used to limit the length of the support plate 41 protruding from the through gap 101. When the support plate 41 extends into the through gap 101, the limiting plate 42 abuts against the side wall of the product 100 to ensure that the support plate 41 is in the correct position, and to prevent the support plate 41 from tilting in the through gap 101. Preferably, the support plate 41 and the limiting plate 42 are arranged vertically.

[0030] The clamping assembly 3 includes a rotary pressing cylinder 31 and a pressing head (not shown). The rotary pressing cylinder 31 is disposed on the rotating workbench 1. The pressing head is disposed at the output end of the rotary pressing cylinder 31 for pressing down the product. A gasket or the like may be placed on the pressing head to avoid damaging the product 100.

[0031] A positioning groove 11 can be set on the rotating workbench 1, and a positioning block 2a is provided in the positioning groove 11. The positioning column 2 is set on the positioning block 2a to extend into the positioning hole 103 at the lower end of the product 100; for different models of products 100, when their positioning holes 103 are located at different positions, different positioning blocks can be replaced to replace positioning columns 2 of different sizes or located at different positions, thereby improving the applicability of the positioning column 2 to the product 100.

[0032] The upper end of the positioning block 2a protrudes from the positioning groove 11 and has a contoured structure to match the lower end of the inner wall of the product 100. The positioning accuracy and convenience are improved through contour matching based on the positioning of the positioning column 2.

[0033] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
