Clamp ring gasket selection device and method

Abstract

The invention, which belongs to the technical field of gearbox clamp ring gasket selection measurement, provides a clamp ring gasket selection device and method, thereby solving problems of low efficiency and inaccuracy of clamp ring gasket selection of the existing gearbox. The device comprises a rack and at least one measuring group that is arranged at the rack and can move along a vertical direction. A clamping device is arranged at the rack and is used for fixing a measured element. The measuring group includes a support frame, a positioning device and a measuring device, wherein the positioning device and the measuring device are installed at the support frame; a contact point is arranged at the positioning device and is used for being abutted against one side wall of a measured clampgroove and determining a reference; and the measuring device includes a measurement barb and a displacement sensor I. Besides, a driving device that is used for driving the measurement barb for insertion into the clamp groove and is abutted against the other side wall of the clamp groove is also arranged at the support frame; and the displacement sensor I is used for measuring displacement of themeasurement barb in a vertical direction. The clamp ring gasket selection device has advantages of high efficiency and precision in selection of the clamp ring gasket.

Description

technical field [0001] The invention belongs to the technical field of gear box snap ring pad selection measurement, and in particular relates to a snap ring pad selection device and a method thereof. Background technique [0002] The gearbox is a very important part of the vehicle. It can change the transmission ratio and expand the torque and speed of the driving wheels. With the development of modern technology, the gearbox has also been upgraded. From the initial manual gearbox to the current stepless gearbox, from no synchronizer to synchronizer, the operation is more and more convenient. The quality of gearbox performance is the key to measure the power, economy and drivability of a car. The current transmission systems mainly include: mechanical transmission, hydraulic transmission, and hydrostatic transmission. The gearbox has manual shifting and power shifting, and the structure has fixed shaft type and planetary type. A gearbox usually includes a gearbox housing...

AI Technical Summary

Problems solved by technology

However, since the clamping mechanism and the measuring mechanism are set separately and occupy a large space, only one set of clamping mechanism and measuring mechanism can be used to select pads for the snap ring. The force of the two mechanisms is likely to be uneven, which affects the measurement accuracy.

When the measurement data needs to be verified, only multiple measurements can be performed, the measurement efficiency is low, and the measurement accuracy is affected. Once the measurement mechanism fails, it cannot be found in time

[0004] The components in the gearbox are complex to cooperate. When two workpieces are axially positioned using snap rings, the existing measurement methods usually measure the two workpieces separately and indirectly calculate the specifications of the snap rings. The measurement efficiency is low, and it is not considered There may be changes in the axial dimensions of the two jobs during the assembly process, and there is a deviation in the size of the pad
