Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and specifically to a rapid shaft parameter detection device. Background Art

[0002] A gear shaft is a common transmission component, and its precision directly affects the operating performance and service life of the equipment. Therefore, accurate detection and quality control of gear shafts are very important.

[0003] Currently, the main method for detecting the coaxiality of gears is to use a coordinate measuring machine for detection. This method can accurately measure various parameters of the gears. However, the operation of the coordinate measuring machine is complex and the detection time is long, which is not conducive to rapid detection in large-scale production.

[0004] To solve the above problems, some enterprises have begun to use some special inspection tools for detection. These usually can only detect the coaxiality of one position at a time and are manually operated. When the coaxiality of multiple parts needs to be detected, they cannot be carried out simultaneously, resulting in cumbersome operation, low efficiency, and low measurement accuracy. In view of the above problems, this application is proposed. Summary of the Invention

Both the head end support wheel group and the middle section support wheel group include at least two rotating wheels, and the power module is used to drive the rotating wheels to rotate, thereby driving the product to rotate.

[0008] The displacement driving module I drives a plurality of coaxiality detection sensors to contact the positions to be detected of the product, realizing synchronous detection of the coaxiality of multiple parts of the product, improving the detection efficiency, and eliminating the need for frequent clamping, position adjustment and other operations, ensuring the detection accuracy.

[0017] Furthermore, the shaft parameter rapid detection device has an automatic detection mode. In this mode, the moving bracket moves on the track module according to the set parameters, switching the detection positions of the coaxiality detection sensor to achieve automatic detection of coaxiality at multiple positions.

[0018] Furthermore, in the automatic detection mode, multiple moving brackets move in a step-by-step manner, and multiple coaxiality detection sensors are used to repeatedly detect the detection points to improve the detection accuracy.
