Clamping force display bench clamp

Abstract

The invention discloses a clamping force display bench clamp, and belongs to the field of clamping devices. The clamping force display bench clamp comprises jaws, a liquid crystal display, a pressuresensor, a signal processing circuit and batteries, the pressure sensor is arranged on the inner side of the fixed jaw of the bench clamp, when a part is clamped between the movable jaw and the fixed jaw of the bench clamp, the pressure sensor detects the change of the clamping force at the fixed jaw, the numerical value of the clamping force is displayed on the liquid crystal display through the signal processing circuit, and the pressure sensor, the signal processing circuit and the liquid crystal display are powered by adopting the batteries. The clamping force display bench clamp has the advantages that when the bench clamp clamps the part, the clamping force can be observed in real time, an operator can accurately adjust the clamping force of the bench clamp according to the material and type of the part, deformation or damage to the part caused by excessive clamping force can be avoided, and looseness of the part in the machining process caused by too small clamping force can alsobe avoided.

Description

technical field [0001] The invention belongs to the field of clamping devices, in particular to a clamping force display vise. Background technique [0002] The vise is widely used in industrial production and is an important clamping device. When processing parts, it is often necessary to tighten the parts with a vise first, and then perform processing procedures such as sawing, grinding and filing. However, due to the material of some parts, such as engineering plastics, soft or easy-to-crack metal parts, if the clamping force is too large when using a vise to clamp, it is easy to cause deformation and damage to the parts. If the clamping force Not enough, and can not play the role of firm clamping. Therefore, operating the vise to clamp the parts only by manual experience judgment may damage the parts and reduce the machining accuracy. [0003] At present, for the parts clamped by the vise, it is generally only possible to judge whether the clamping force is appropriat...

Problems solved by technology

However, due to the material of some parts, such as engineering plastics, soft or easy-to-crack metal parts, if the clamping force is too large when using a vise to clamp, it is easy to cause deformation and damage to the parts. If the clamping force Not enough, and it can't play a role of stable clamping

Therefore, operating the vise to clamp the parts only by manual experience judgment may damage the parts and reduce the machining accuracy

[0003] At present, for the parts clamped by the vise, it is generally only possible to judge whether the clamping force is appropriate based on the experience of the workers. There is no accurate detection method to measure the clamping force, which often leads to deformation or damage of the parts, or the parts are in It was scrapped due to looseness during processing, so it is urgent to provide a new type of clamping force display vise to solve the above problems
