Problems solved by technology

At present, brake pad enterprises generally use manual metering method and knife-edge ruler to check the flatness of brake pads, and read the maximum and minimum values ​​manually as flatness judgment indicators. This method requires high skills for workers and workers work for long hours. Easy fatigue, high labor intensity and other problems
And manual reading is prone to misoperation, affecting the measurement accuracy

Abstract

The invention discloses a group measurement method flatness detection apparatus. A frame is provided with a workpiece adaptive compaction mechanism, and a detection positioning device which horizontally moves in a predetermined direction along a guide rail. The frame is provided with a fixedly-mounted group measurement sensor set. The group measurement sensor set comprises more than three LVDT sensor groups. The group measurement sensor set is fixed on the frame through a sensor installation plate. The sensor installation plate is provided with a three-point positioning mechanism and a spacing mechanism. The detection positioning device is provided with a detected workpiece. The detected workpiece can horizontally slide on the positioning device in the guide rail direction. The workpiece adaptive compaction mechanism drives a positioning block through a cylinder and the like. The detection positioning device positioning block is provided with more than three positioning push needles not on the same straight line. The positioning push needles are sleeved by spring adaptive mechanisms. The invention can reduce the labor cost in the brake disc flatness detection, and improves the measurement accuracy and the working efficiency.

Description

technical field [0001] The invention relates to a flatness detection device, in particular to a flatness detection device for a brake pad with convex points. Background technique [0002] In industries such as auto parts, it is usually necessary to take the flatness detection of parts as a key technical indicator. Automobile brake pads are the key components to ensure the safety of automobiles, and their flatness is an important shape and position error to test the quality of brake pads. At present, brake pad enterprises generally use manual metering method and knife-edge ruler to test the flatness of brake pads, and read the maximum and minimum values ​​manually as flatness judgment indicators. This method requires high skill requirements for workers and workers work for long hours Easy fatigue, high labor intensity and other problems. And manual reading is prone to misoperation, affecting the measurement accuracy. Contents of the invention [0003] The present inventi...
