Description

[Technical Field]

[0001] This invention relates to the field of product surface processing technology, and in particular to a positioning and clamping device for assisting in the processing of products. [Background Technology]

[0002] Some products require the machining of grooves and bosses on their upper surface during surface treatment. Therefore, machining with the upper surface of the product as the reference surface can ensure the maximum machining accuracy. However, the commonly used machining method is to press and fix the product to be processed on a fixed machining table, and then use the machining table, i.e. the bottom surface of the product, as the machining reference surface for machining. However, products generally have their own thickness tolerance, which will cause the machining reference surface to be inconsistent, resulting in deviations in machining accuracy and affecting product yield.

[0003] In view of this, the present invention provides a positioning and clamping device for assisting in the processing of products to solve the above problems. [Summary of the Invention]

[0004] The technical problem to be solved by the present invention is that, in order to solve the problem that the existing method of processing the upper surface of a product is to fix the product on a processing table and then use the processing table, i.e. the bottom surface of the product, as the reference surface for processing, the product itself has thickness tolerance, which will cause the processing reference surface to be inconsistent, resulting in deviations in processing accuracy and affecting the product yield. Therefore, the present invention provides a positioning and clamping device to assist in processing products to solve the above problems.

[0005] The solution to the technical problem of this invention is: a positioning and clamping device for assisting in the processing of products, comprising:

[0006] A base plate, wherein a support plate and a first driving device are provided on the base plate;

[0007] A top plate is fixedly connected to the end of the support plate away from the bottom plate, and a processing opening is provided on the end face of the top plate near the processing machine table;

[0008] A positioning plate is fixed to the first driving end of the first driving device. The positioning plate is used to place and position the product to be processed. The first driving device is used to drive the positioning plate to move and make the reference surface of the product to be processed fit with the side of the top plate away from the machine table.

[0009] Preferably, a guide post is provided between the bottom plate and the top plate, and a guide sleeve is provided on the positioning plate. The guide sleeve passes through the guide post, and the guide sleeve cooperates with the guide post to guide the movement direction of the positioning plate.

[0010] Preferably, the positioning plate is provided with at least one positioning groove for positioning the product.

[0011] Preferably, a tightening mechanism is further provided on one side of the support plate. The tightening mechanism includes a fixed plate, a second driving device, a first tightening block, and a second tightening block. The fixed plate is fixed to the side of the support plate away from the positioning plate. The second driving device is fixed to the fixed plate. The second driving end of the second driving device is connected to the second tightening block. The support plate has a hollow hole for the second driving end and the second tightening block to extend into. The first tightening block is located between the first driving end and the positioning plate. The first tightening block has a first tightening surface, and the second tightening block has a second tightening surface. The first tightening surface and the second tightening surface are matching inclined surfaces. The tightening mechanism is used to support and tighten the positioning plate when the positioning plate is pressed towards the top plate to prevent the positioning plate from shifting.

[0012] The beneficial effects of the present invention are that the positioning and clamping device for auxiliary processing of products of the present invention, by setting a movable positioning plate, places the product to be processed on the positioning plate for positioning, and then uses a first driving device to drive the positioning plate and the product to be processed to press together towards the top plate. At the same time, a clamping mechanism is used to clamp the positioning plate during the product processing to prevent the positioning plate from shifting. Then, the product to be processed is processed through the processing opening on the top plate with the product processing surface as the reference surface, thereby improving the processing accuracy and product yield.
