Problems solved by technology

This measurement method has low efficiency, heavy workload, long test time, and the staff is prone to fatigue and large errors may occur
In the latter measurement method, the measurement process and data processing are carried out automatically, and the measurement efficiency is high, which not only ensures the measurement accuracy but also reduces the fatigue strength, but has higher requirements on the rotation accuracy of the cam and the clamping accuracy of the related fixtures.

Abstract

The invention discloses a worm gear type cam profile detector, which includes a box body, a transmission unit and a control unit, and the transmission unit includes a worm wheel, a worm, a first bearing, a second bearing, a third bearing, a first The transmission shaft, the second transmission shaft, the gear shaft, the spur gear, the fixture, the fourth bearing, the first bevel gear and the second bevel gear; the control unit includes a distance sensor, a circular grating and a control module. The rotation of the transmission unit drives the rotation of the measured cam on the fixture, and the rotation information of the measured cam is collected to the control module through the distance sensor and the circular grating. This profile detector is small in size, low in cost, fast in detection speed, high in measurement accuracy and good in practicability, and can meet the needs of on-line detection in production lines.

Description

technical field [0001] The invention relates to the technical field of cam profile measuring instruments, in particular to a worm gear type cam profile measuring instrument. Background technique [0002] The cam and the measurement parameters of the cam mainly include: lift, multiple cam mutual space position angles, radial runout, speed and acceleration and other related parameters. The cam lift and the spatial position angle are the main parameters of the two measurement parameters. The measurement methods mainly include manual measurement with optical instruments and measurement with a special cam automatic measuring instrument. The former method uses the optical dividing head to divide, and the Abbe measuring head is used to measure the lift, and the measurement results are calculated by the measuring personnel. This measurement method has low efficiency, heavy workload, and long test time, and the staff is prone to fatigue and large errors may occur. In the latter mea...
