Multifunctional clamp with pressure sensor, control method and workpiece clamping device

Abstract

The invention belongs to the technical field of constraint clamps, and discloses a multifunctional clamp with a pressure sensor, a control method and a workpiece clamping device. The multifunctional clamp with the pressure sensor is provided with a clamping plate used for supporting a workpiece, a force applying structure used for applying clamping force to the workpiece, a pressure sensor used for monitoring and measuring the clamping force, and a supporting structure providing a supporting effect for the whole clamp. According to the multifunctional clamp with the pressure sensor, the clamping position and mode are flexible, assembling deformation is carried out according to the clamping position requirement, and a gantry type clamp, a C type clamp and an I type clamp are formed to meet the requirement for different clamping positions of different workpieces; a lower clamping plate can be replaced by an arc plate, so that a cylindrical workpiece is clamped and fixed; a force application bolt can provide clamping force higher and more stable than the clamping force of a traditional clamp, and the overall structure is high in stability; the maintenance method in the using process is simple, and the service life is long; and meanwhile, the force applying structure is provided with the pressure sensor, the value of the clamping force of the clamp can be accurately measured, and the clamp can be used for some situations with specific requirements for the clamping force.

Description

technical field [0001] The invention belongs to the technical field of constraint fixtures, and in particular relates to a multifunctional fixture with a pressure sensor, a control method, and a workpiece clamping device. Background technique [0002] At present, fixtures play an indispensable role in production and life. The use of clamping devices can first create a strong mounting point for the workpiece, thereby providing support during operation, and improving the accuracy, reliability and interchangeability of the finished part. It also reduces working time with fast setup and smooth part-to-part transitions. In addition, the complexity of the process and the energy and physical effort required for concentrated fixing are reduced, thereby increasing the safety of production personnel. In a word, the fixture constraint device is a process device that enables the workpiece to be accurately positioned, firmly clamped and stably clamped according to certain technical req...

AI Technical Summary

Problems solved by technology

[0005] (1) The function of the existing fixture is relatively single, and the holding position and method are fixed, which cannot be used flexibly

[0006] (2) The existing fixture device is often not stable enough during use, and it is easy to generate disturbance during use

[0007] (3) The size of the existing fixtures is mostly a standard fixed size, and the workpiece cannot find a fixture device corresponding to the appropriate size

[0008] (4) The materials of the existing fixture devices are mostly cast iron materials, which are prone to breakage during use, and are difficult to repair if damaged during use

[0009] (5) For accurate experiments, the traditional fixture system cannot measure the clamping force, so as to quantitatively describe the clamping degree
