Floating pressing plate head with adjustable clamping force

Abstract

The invention relates to a floating pressing plate head with adjustable clamping force. The floating pressing plate head with the adjustable clamping force comprises a connector, a movable pressing head, an elastic piece, a pre-adjusting piece and a pressure gauge, wherein the connector can be fixedly connected with an external pressing plate and is provided with a vertically-through hollow cavity, the two ends of the movable pressing head extend out of the upper end and the lower end of the hollow cavity correspondingly, the two ends of the elastic piece abut against the movable pressing head and the top end of the hollow cavity correspondingly, the pre-adjusting piece is fixedly connected with the top of the movable pressing head and abuts against the top of the connector, the pressure gauge is fixed above the connector, and a probe of the pressure gauge further abuts against the top end of the movable pressing head. Compared with the prior art, the floating pressing plate head with the adjustable clamping force has the advantages that fixing of a traditional pressing plate head is changed into floating adjustment, different types of floating heads can be selected according to the pressing force range, and the situation of pressing deformation is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of numerical control machining key parts and relates to a floating platen head with adjustable clamping force. Background technique [0002] At present, the clamping before product processing and testing mainly includes flat product clamping, vacuum suction cup clamping, pressure plate clamping, chuck clamping and side pressure clamping, etc. Each clamping method is only suitable for one type of product. For thin-walled parts with complex structure, the clamping method of pressing plate is mainly used. Due to the complex structure of the product, it is inconvenient to use auxiliary support, which is expensive and inefficient. ; Without auxiliary support, it is easy to clamp deformation or clamp loose. When the clamping force is too large, the product will be severely deformed by the force, which will affect the product quality and cause the product to be scrapped. When the clamping force is too small, the ...

AI Technical Summary

Problems solved by technology

Each clamping method is only suitable for one type of product. For thin-walled parts with complex structure, the clamping method of pressing plate is mainly used. Due to the complex structure of the product, it is inconvenient to use auxiliary support, which is expensive and inefficient. ; Without auxiliary support, it is easy to clamp deformation or clamp loose

When the clamping force is too large, the product will be severely deformed by the force, which will affect the product quality and cause the product to be scrapped

When the clamping force is too small, the product will move during processing, resulting in product scrap or even tool damage

Therefore, the magnitude of the clamping force is very difficult to control, and during the processing of the product, after cutting off part of the material, due to internal stress and product deformation, the support strength of the product becomes lower and deformation occurs at the same time, which easily causes the product to lose clamping force, greatly increasing the risk of product scrap and tool damage

At present, a large clamping force is mostly used to prevent such clamping failure, and at the same time, due to excessive clamping force, the scrap rate of industrial products is increased and the quality of the product is reduced.
