Semi-pneumatic hanging table sweeping-head machining clamp assembly

Abstract

The invention discloses a semi-pneumatic hanging table sweeping-head machining clamp assembly. A semi-pneumatic hanging table sweeping-head machining clamp assembly comprises a base plate, wherein a fixed block is arranged at one end of the base plate, a clamping slide block capable of horizontally moving with respect to the fixed block is arranged at the other end of the base plate, and a V-shaped groove is formed in the surface of the side, with respect to the clamping slide block, of the fixed block. The clamping slide block is driven by an air cylinder, the air cylinder is connected with a manual reversing valve and an air source through two air pipes, and a reversing valve handle is arranged on the manual reversing valve. By adopting one end of the V-shaped groove as a fixed end, using the air cylinder as a clamping force supply source and adopting a hand pull mode, the standard of a product is fit with the positioning standard of the clamp assembly, switching control of opening and clamping motions of the clamp assembly is performed by utilizing the manual reversing valve, and the clamp assembly simple and quick to operate and high in machining accuracy.

Description

technical field [0001] The invention relates to a semi-pneumatic hanging table sweeping head processing and clamping group, which belongs to the technical field of workpiece processing. Background technique [0002] For the processing of the head of the ejector pin, it is necessary to fix the pole and use the grinding wheel to finish it. The existing processing methods are as follows. [0003] One is to use a special row clamp to fix the thimble vertically and finish it with the front of the grinding wheel. The disadvantage of this processing method is that it is suitable for a small range of specifications, and the thimble cannot be processed for thick and long types (total length > 300mm, rod diameter > Φ16mm). . [0004] The other is to use a common vise to fix the thimble horizontally and finish it with the side of the grinding wheel. The disadvantage of this processing method is that due to the structure of the common vise (the V-groove is on the side of the sli...

[0003] One is to use a special row clamp to fix the thimble vertically and finish it with the front of the grinding wheel. The disadvantage of this processing method is that it is suitable for a small range of specifications, and the thimble cannot be processed for thick and long types (total length > 300mm, rod diameter > Φ16mm).

[0004] The other is to use a common vise to fix the thimble horizontally and finish it with the side of the grinding wheel. The disadvantage of this processing method is that due to the structure of the common vise (the V-groove is on the side of the slider), the thick / long thimble is due to Due to the gravity factor, it cannot be clamped flat, and the repeatability is poor, resulting in the unfavorable situation that the end surface of the thimble and the shaft are tilted (the error of high and low points is 0.05~0.1), which seriously affects the quality; the clamping needs to be inserted from the front end of the vise into the jaw of the vise for clamping Therefore, it will inevitably cause shovel (scraping) friction between the sharp edge of the thimble and the clamping surface of the vise, causing damage to the vise (scraping irregular grooves on the clamping surface), seriously affecting the accuracy; manual operation is time-consuming and laborious
