Description

TECHNICAL FIELD

[0001] The utility model relates to a laser detection oil seal runout tool belongs to the differential assembly technical field. BACKGROUND

[0002] Oil seal runout detection is one of differential assembly production and manufacture key links. Because of the particularity of oil seal press fitting, needs detecting oil seal runout after press fitting when assembling, and oil seal runout is too big, will lead to oil seepage under assembly state, plays decisive role to differential assembly life. SUMMARY

[0003] The utility model aims at providing a kind of laser detection oil seal runout tool, accurate detection can be realized to oil seal runout, solve the problems in the background art.

[0004] The technical scheme of the utility model is:

[0005] A kind of laser detection oil seal runout tool, including base, positioning column, vertical support, cross support, positioning sleeve, push force needle cage, rotating column, positioning plate and laser displacement sensor, positioning column and vertical support are respectively fixed on base, cross support is fixed on vertical support, cross support and base are arranged in parallel up and down, positioning sleeve is fixed on the through-hole of cross support, push force needle cage is fixed on positioning sleeve, rotating column is placed on push force needle cage and passes through positioning sleeve, and laser displacement sensor is fixed at the lower end of rotating column.

[0006] Further, the positioning column is matched with the detected part.

[0007] Further, the laser displacement sensor is located directly above the detected part.

[0008] Further, the rotating column is rotatably connected with the push force needle cage and the positioning sleeve by the push force needle bearing.

[0009] When using the utility model, first, the measured part is placed on the base, the rotating column is rotated, the laser displacement sensor is rotated one circle along with the rotating column, the laser displacement sensor measures the distance from the laser displacement sensor to the surface of the measured part in real time, and the difference between the maximum value and the minimum value of the measured distance is obtained, which is the oil seal runout value of the measured part.

[0010] The utility model has the advantages of accurate measurement of oil seal runout, simple operation, safety in use, improved product quality and ensured differential assembly life. BRIEF DESCRIPTION OF DRAWINGS
