Motor shaft clamping tool, circumferential correction device and keyway symmetry degree detection tool

Abstract

The invention discloses a motor shaft clamping tool, a circumferential correction device and a keyway symmetry degree detection tool. The clamping tool comprises a lower bearing base; a front fixed base and a rear base driving device are mounted on the lower bearing base, and the output end of the rear base driving device is connected with a rear movable base; the front fixed base is rotatably connected with a driving centre, and the rear movable base is rotatably connected with a driven centre; the lower bearing base is further provided with two clamping driving devices which are arranged ina bilateral symmetry mode; and the output ends of the clamping driving devices are connected with clamping assemblies. The clamping tool can stably adjust and fix the circumferential position of a shaft to be measured. According to the correction device, through cooperation of the image collecting assembly and the auxiliary light source base, whether the two side faces of the keyway are perpendicular to the horizontal plane or not can be accurately judged. According to the motor shaft keyway symmetry degree detection tool, good contact between the positioning block assembly and the keyway canbe effectively ensured, and an accurate detection result can be obtained.

Description

technical field [0001] The invention belongs to the technical field of motor shaft detection, and in particular relates to a motor shaft clamping tool, a circumferential correction device and a keyway symmetry inspection tool. Background technique [0002] A shaft with a keyway is one of the common parts in mechanical products, and it is widely used in various mechanical rotating devices. As a coupling mechanism for transmitting torque, the keyway needs to be matched with the key. In order to ensure a stable fit between the two, it is particularly important to detect the symmetry of the keyway. [0003] At present, the testing equipment for keyway symmetry is as follows: figure 1 As shown, it includes a support platform, a V-shaped block, a positioning block and a measuring frame with an indicator. The operation is as follows: place the shaft to be measured in the notch of the V-shaped block, and fit the positioning block into the keyway of the shaft to be measured ; Adjus...

AI Technical Summary

Problems solved by technology

[0004] In practical application, the aforementioned device and detection method are not only time-consuming and laborious, but also have the following problems: 1. When using an indicator to test the height values ​​at both ends of the positioning block, due to the lack of auxiliary positioning structures to fix the shaft, the shaft is very prone to Accidental shaking, like this, will also affect the test results

2. When rotating the shaft in the circumferential direction, the parallelism between the positioning block and the supporting platform is mostly observed by the naked eye, which will seriously affect the accuracy of detection

3. After the positioning block is assembled into the keyway, the positioning block designed as a whole does not necessarily have a good contact with the keyway, so it will inevitably affect the test results
