Abstract

The invention discloses a pressure sensing type electromechanical air pressure detection device which comprises an operation table and two fixing blocks arranged on the operation table, two hollow rectangular detection clamps are arranged between the two fixing blocks, the side faces of the rectangular detection clamps are fixedly connected with threaded rods, and the other ends of the threaded rods penetrate through the fixing blocks and are in threaded connection with the fixing blocks. An arc-shaped detection clamp is arranged in each hollow rectangular detection clamp in a sliding manner.A push-out mechanism is further arranged on one side of each arc-shaped detection clamp, the push-out mechanisms penetrate through the side walls of the rectangular detection clamps and can push the arc-shaped detection clamps out of the notches in the rectangular detection clamps. The device further comprises pressure sensing modules, and each push-pull baffle and the corresponding arc-shaped detection clamp are provided with the corresponding pressure sensing modules. According to the device, a square workpiece and an arc-shaped workpiece can be in close contact with the clamp in the air pressure detection process, the situation that the local pressure is too large is avoided, and the measurement result is more centralized and accurate.

Description

technical field [0001] The invention belongs to the technical field of air pressure detection devices, and in particular relates to a pressure-sensing electromechanical pressure detection device. Background technique [0002] In electromechanical operation, when using CNC machine tools to process the shell or middle frame of electronic products (such as mobile phones, tablet computers, etc.), fixtures are usually used to clamp the workpiece to be processed on the positioning surface of the fixture, and then use CNC The tool of the machine tool processes the workpiece to realize the processing of the workpiece. [0003] The fixtures in the prior art need to detect the air pressure held by them during the working process. During the air pressure detection process, due to the different shapes of the clamping surfaces, there is a loose connection between the clamping surface and the working surface during the air pressure measurement process. As a result, the local pressure is ...
