Description

Technical Field

[0001] The utility model belongs to the technical field of composite material product processing, and relates to a composite tooling fixture for improving the rigidity of the composite material when grooving, in particular to a clamping device for improving the processing efficiency of an equivalent flat plate. Background Art

[0002] Since the equivalent flat plate is a thin-walled part with a high adhesive content and a large number of slots, the current processing method is to use 0.7mm double-sided tape to bond the workpiece and use a 1.5 end mill for processing. This causes tool sticking, tool breakage, and easy delamination during product disassembly. In addition, the processing efficiency is low. In the face of the current emergency of various production tasks, this processing method seriously affects the production progress of other products and causes serious waste of tool consumption. It is urgent to change its processing method.

[0003] If the equivalent plate is clamped by the traditional clamping method, the structure of the equivalent plate will inevitably be damaged. Utility Model Content

[0004] In order to solve the problem that the workpiece is too thin and has no rigidity to use a pressing plate, and can only be processed by using double-sided tape, as well as the problem of damage to the workpiece when clamping the workpiece during processing, the utility model provides a clamping device that improves the processing efficiency of the equivalent flat plate, thereby improving the processing efficiency and the product qualification rate.

[0005] The technical solution of the utility model is as follows:

[0006] A clamping device for improving the processing efficiency of equivalent flat plates comprises a clamp body, which is a long strip structure. The length of the clamp body matches the length of the equivalent flat plate to be processed. A guide groove along the length direction is opened on the top of the clamp body. The width of the guide groove is at least greater than twice the thickness of the equivalent flat plate to be processed. A through hole is provided between one side of the guide groove and the outer surface of the clamp body. A fastening device enters the guide groove through the through hole from the outside of the clamp body to fix the equivalent flat plate to be processed.

[0007] Further, the clamp body is a hard structure.

[0008] Furthermore, the through hole is a fastening bolt hole, and the fastening device is a clamping bolt; and the plurality of fastening bolt holes are arranged at intervals of 70 mm to 80 mm along the length direction.

[0009] Furthermore, a compression protection pad is provided at the active end of the clamping bolt, and the compression protection pad is a soft structure.

[0010] Furthermore, the guide groove is a square groove.

[0011] Furthermore, the depth of the guide groove is 1 / 3 to 2 / 3 of the width of the equivalent plate to be processed.

[0012] Furthermore, the through hole is arranged in the upper and lower directions of the fixture body corresponding to the middle position of the width after the equivalent flat plate to be processed is placed in the guide groove.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The utility model changes the previous pasting process to the current vertical clamping process using a homemade fixture, thereby avoiding the risk of the milling cutter processing the tape during the bonding process using double-sided tape, thereby affecting the product.

[0015] 2. The structural features of the utility model can provide effective strength for non-rigid composite materials through multiple rounds of adjustment, and can also fine-tune the workpiece. This clamping device can achieve vertical processing.

[0016] 3. When the fixture of the utility model is used to clamp workpieces for processing, two pieces can be processed at one time, that is, two product parts can be clamped at one time.

[0017] 4. The utility model can increase the height of the back to facilitate the expansion of the depth of the square groove, thereby being able to adjust the equivalent flat plate with different processing requirements and realize the multi-batch use of the fixture.
