Gauge stand for repeated positioning detection

Abstract

The invention provides a gauge stand for repeated positioning detection. The gauge stand comprises a base, a front side wall, a rear side wall, a linear guide rail, a cushion block, a pre-tightening nut, a spring positioning pin, a pre-tightening spring, a dial indicator seat, a firing pin, an adjusting bolt, a dial indicator and a locking nut; the base is connected with the vertical front side wall and back side wall; 4 to 6 bolt holes are formed in on the base; the linear guide is located on the base and is fixedly connected with the base through the bolt holes; the spring positioning pin is located in the rear side wall; the pre-tightening spring sleeves the spring positioning pin; the pre-tightening nut is connected with the spring positioning pin; the dial indicator seat is located on the linear guide rail and is connected with the linear guide rail; the adjusting bolt is located in the front side wall; the locking nut is connected with the adjusting bolt; the firing pin is located at the side wall of the linear guide rail; the dial indicator is arranged on the dial indicator seat; and the cushion block is arranged on the linear guide rail. With the gauge stand for repeated positioning detection adopted, gear alignment detection accuracy of gear alignment phase angles of the same set of planetary gear assembly in a combined planetary gear alignment process can be improved.

Description

technical field [0001] The invention relates to a high-precision detection tool, in particular to a watch base for repeated positioning detection. Background technique [0002] In the process of compound planetary gear alignment, there are at least three sets of planetary gears in a gearbox, so it is required that the teeth on the gear shaft and the teeth of the disc gear have a certain angular relationship during the assembly process, and three or more sets of gear components The angle must be kept consistent, and the consistency accuracy of the angle of the same set of planetary gear assemblies is very high, so the detection of the phase angle of the teeth of the same set of planetary gear assemblies is very important. The accuracy of tooth alignment detection is low, and there is no tooling and table seat that can repeatedly position and detect the gears. The consistency of the phase angle of the teeth of the same group of planetary gear assemblies is poor, which will inc...

[0002] In the process of compound planetary gear alignment, there are at least three sets of planetary gears in a gearbox, so it is required that the teeth on the gear shaft and the teeth of the disc gear have a certain angular relationship during the assembly process, and three or more sets of gear components The angle must be kept consistent, and the consistency accuracy of the angle of the same set of planetary gear assemblies is very high, so the detection of the phase angle of the teeth of the same set of planetary gear assemblies is very important. The accuracy of tooth alignment detection is low, and there is no tooling and table base that can repeatedly position and detect gears. The consistency of the tooth phase angle of the same group of planetary gear assemblies is poor, which will increase gear wear and reduce the service life of parts.
