Novel type dual-spring constant-force-control clamping device

Abstract

The invention discloses a novel type dual-spring constant-force-control clamping device. The novel type dual-spring constant-force-control clamping device comprises a hollow body, a clamping block, aforce transmission assembly, a connecting block, a cover plate, an ejector rod and a power device, wherein the clamping block, the force transmission assembly, the connecting block and the cover plateare mounted in the body from front to rear; the force transmission assembly comprises a belleville spring, a force transmission block, a cylindrical spring, a guide rod and a guide block; the belleville spring is mounted between the rear end of the clamping block and the force transmission block; and the diameter of the position, close to the tail part, of the ejector rod is suddenly increased toform a step. The novel type dual-spring constant-force-control clamping device achieves the technical purpose of accurately controlling clamping force in a clamping process of a fragile material.

Description

technical field [0001] The invention relates to a clamping device for clamping workpieces, in particular to a novel dual-spring type constant force control clamping device. Background technique [0002] With the improvement of people's living standards, floor tiles, wall tiles and glass products for home decoration need to be carved or cut. Since floor tiles, wall tiles and glass are all brittle materials, when the clamping force is too large, it is easy to If it is crushed and the clamping force is too small, accidents will easily occur during the processing. Although the overflow valve can be used to control the clamping force in the hydraulic system or pneumatic system, the adjustment is not convenient enough, and the hydraulic system or pneumatic system It is prone to failure, and it is difficult to overhaul when a failure occurs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a novel dual-spring type const...
