Fixing mechanism

Abstract

The invention provides a fixing mechanism and relates to the field of machining, in particular to the fixing mechanism used for automatic locking of aluminum extrusion products. The fixing mechanism comprises a power device, a supporting frame, a material platform and a clamping device. The material platform is used for carrying workpieces and is fixedly connected with the supporting frame. The clamping device comprises two guide plates, two clamping plates and a movable plate, wherein the two guide plates are arranged in opposite, the two clamping plates are located on the inner sides of the two guide plates respectively and arranged in opposite, the movable plate is arranged between the two clamping plates, the two clamping plates are hinged to the two sides of the movable plate, the inner surface of each guide plate is provided with an inclined surface and a vertical surface in abut joint with the outer side of the corresponding clamping plate, each inclined surface extends downwards from the top end of the corresponding guide plate and gradually inclines inwards, and the top end of each vertical surface is connected with the bottom end of the corresponding inclined surface. The power device is used for driving the movable plate to vertically move.

Description

Technical field [0001] The invention relates to the field of machining, in particular to a fixing mechanism. Background technique [0002] With the development of highly integrated electronic components on PCB boards, the large heat generation of electronic components and the excessive concentration of local parts on the PCB board have become a major problem that electronic products need to solve urgently. Because aluminum metal has good thermal conductivity, and the production threshold of aluminum products is not high, and the cost is low, aluminum heat sinks are commonly used to solve the heat dissipation problem of electronic products. [0003] Generally, aluminum heat sinks are often made by aluminum extrusion. The aluminum extrusion process is used to produce aluminum extrusion products. If the aluminum extrusion products have a flat surface, they often need to be leveled, otherwise it will affect the processing accuracy of the product surface, resulting in defective product...

AI Technical Summary

Problems solved by technology

The aluminum extrusion process produces aluminum extrusion products. For aluminum extrusion products with flat surfaces, it is often necessary to level them, otherwise it will affect the processing accuracy of the product surface, resulting in defective products.

During the leveling operation, the aluminum heat sink must be fixed. The traditional fixing method is to use a flat-mouth vise to fix it, but this fixing method needs to be locked manually, which is labor-intensive and low in production efficiency.
