Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation plate processing fixtures, and specifically relates to a heat dissipation plate processing fixture. Background Art

[0002] A heat dissipation plate processing fixture is a fixture required for processing automotive heat dissipation plate workpieces, also known as a clamp, which plays a role in fixing the heat dissipation plate to be processed, or places the heat dissipation plate to be processed in a relatively stable and fixed position, facilitating one-time processing completion without being affected by external pressure during processing and resulting in offset or displacement, which may lead to processing failure. Traditional processing fixtures can only play a role in fixing workpieces and are not convenient for taking out workpieces, making it inconvenient for material taking.

[0003] Existing heat dissipation plate processing fixtures can only fix workpieces and are not convenient for taking out workpieces. For example, a radiator processing fixture disclosed in the patent with the publication number CN211219517U includes a bottom plate. A first cylinder, a first positioning baffle, and a second cylinder are sequentially installed on the top of the bottom plate from left to right. The first cylinder and the second cylinder are arranged oppositely. A second positioning baffle that can move up and down is also installed on one side of the first cylinder and the first positioning baffle. A third positioning baffle that can move up and down is also installed on one side of the first positioning baffle and the second cylinder. This radiator processing fixture can fix two radiators at one time. One radiator is fixed between the first cylinder, the first positioning baffle, and the second positioning baffle, and the other radiator is fixed between the first positioning baffle, the second cylinder, and the third positioning baffle. The first cylinder and the second cylinder are provided with two rows arranged side by side, capable of clamping and fixing larger radiators. However, after clamping and fixing them, the operation of taking them out is relatively cumbersome, making it inconvenient for part taking and resulting in low part taking efficiency.

[0004] Therefore, it is very necessary to invent a heat dissipation plate processing fixture to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a heat dissipation plate processing fixture to solve the problem that the heat dissipation plate processing fixture in the prior art is not convenient for taking out the processed heat dissipation plate.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A processing fixture for a heat dissipation plate, including a processing fixture main body, a buffer plate, a rotating mechanism and a clamping plate. The processing fixture main body is a rectangular frame, and a buffer plate is fixedly arranged at the bottom of the processing fixture main body. A rotating mechanism is arranged on the side of the processing fixture main body, and a clamping plate is connected to the rotating mechanism. A metal processing plate is installed in the clamping plate. The size of the metal processing plate is adapted to the size of the heat dissipation plate main body, and the position of the through hole opened on the metal processing plate corresponds to the position of the protrusion on the heat dissipation plate main body. A plurality of fixing columns are arranged at the inner bottom of the processing fixture main body, and support pads are fixedly arranged at the four corners inside the processing fixture main body. The height of the bottom of the support pad is flush with the height of the top of the fixing column.

[0007] Preferably, the fixing column is made of an elastic material, and the heat dissipation plate main body can be placed on the fixing column, and the bottom surface of the heat dissipation plate main body can contact the top block.

[0008] Preferably, a spring is connected to the top block, and the top end of the spring is fixedly connected to the top end of the sliding groove. The sliding groove is opened on both the support pad and the processing fixture main body, and the positions correspond to each other and the sizes are the same.

[0009] Preferably, the limiting member is fixedly connected to the top block, and the top block and the limiting member penetrate through the sliding grooves in the processing fixture main body and the support pad. The length between the top block and the limiting member is greater than the thickness of the processing fixture main body and the support pad.

[0010] Preferably, only one set of two opposite support pads among the plurality of support pads are provided with sliding grooves, and the top block and the spring are arranged in the sliding grooves.

[0011] Preferably, the support pad is L-shaped and is made of an elastic material.

[0012] Preferably, the buffer plate can be placed on the conveyor belt. The buffer plate is made of rubber material, and the size of the buffer plate completely matches the size of the bottom surface of the processing fixture main body.

[0013] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0014] 1. By arranging fixing columns in the processing fixture main body, the heat dissipation plate main body to be processed is initially fixed in position. After the heat dissipation plate main body is placed on the fixing columns, the top blocks in the four support pads inside the processing fixture main body will be pressed down to the lowest position of the sliding grooves, and then lifted by the elastic potential energy of the springs when the clamping plate is opened, which is convenient for taking out the heat dissipation plate main body from the processing fixture main body;

[0015] 2. The position of the heat dissipation plate body is fixed again when it is placed by means of the support pads arranged at the four corners inside the processing fixture body, and the bottom of the heat dissipation plate is lifted by the top block and the limit block in the chute, which is convenient for sampling.
