Fixture of clamping radiating fins at high precision

Abstract

The invention relates to a fixture of clamping radiating fins at high precision. The fixture comprises a base plate and a hold-down device; the hold-down device is arranged in holes formed in the base plate along the rotating axis; the hold-down device comprises a rotating hold-down cylinder, a rotating arm, a rotating arm holder and a cushion; the rotating hold-down cylinder is mounted in a hole formed in the rotating axis of the base plate; the rotating arm is used for holding down or avoiding the radiating fin workpiece by rotating by different angles. The clamping device comprises a cylinder mounting base, a two-axis clamping cylinder mounted on the cylinder mounting base, a first baffle plate fixed on one side, close to the radiating fin workpiece, of the two-axis clamping cylinder, a base plate mounted on the other side of the radiating fin workpiece, and a positioning block corresponding to the first baffle plate. The fixture is capable of actively avoiding the machining region during radiating fin surface machining; the whole upper surface of the radiating fin can be machined at a time without the machining quality problems such as tool mark; the production efficiency and the machining accuracy are improved.

Description

technical field [0001] The invention relates to the field of fixtures for numerically controlled machine tools, in particular to a fixture for clamping cooling fins with high precision. Background technique [0002] With the development of numerical control technology, many parts of products are processed by CNC machine tools. Generally, fixtures need to be installed on the machine tool to clamp the workpiece or guide the tool. Its function is to position the workpiece so that the workpiece can obtain relative The correct position, and reliable clamping of the workpiece. [0003] At present, for the processing of long strip-shaped heat sink workpieces in the market, manual compression is generally used. During the processing of workpieces at different angles, it is necessary to manually adjust the compression position of the compression device so that it does not affect the The operation of the processing equipment has a low degree of automation and low production efficienc...

[0003] At present, for the processing of long strip-shaped heat sink workpieces in the market, manual compression is generally used. During the processing of workpieces at different angles, manual adjustment of the compression position of the compression device is required so that it does not affect the The operation of processing equipment has low degree of automation and low production efficiency, and the step-by-step operation on the same surface is easy to form knife marks on the surface of the heat sink, which reduces the processing quality of the product
