Turning over tool for accurate grinding of automobile gearbox transmission gear

Abstract

The invention relates to the technical field of automobile gearbox transmission gears, and discloses a turning over tool for accurate grinding of an automobile gearbox transmission gear. The turning over tool comprises a fixing frame plate, an turning over grinding mechanism is arranged inside the fixing frame plate, and the turning over grinding mechanism comprises a fixing column, a motor, a motor shaft, a first bearing, a connecting rod, a first fixing cylinder, a partition plate, a clamping block and a first spring. According to the turning over tool, by arranging a first spring, a first fixing rod, a second bearing and second fixing blocks in the first fixing cylinder, gears of different sizes can be placed between the two second fixing blocks by using the first spring and the first fixing rod, therefore the gears of different sizes can be clamped and ground, and the second fixing blocks can be rotated through the second bearing, so that the second fixing blocks are turned over, accurate grinding and rough grinding are switched according to the grinding requirement for switching, and in addition, the side faces of the gears can be ground through the second grinding blocks on the first fixing cylinder.

Description

technical field [0001] The invention relates to the technical field of transmission gears of automobile transmissions, in particular to an overturning tool for precise grinding of transmission gears of automobile transmissions. Background technique [0002] With the continuous improvement of people's living standards, the number of automobiles continues to increase, and the number of parts manufacturers manufacturing automobiles and supporting facilities in the market continues to increase. The gearbox is a very important part of the vehicle. It can change the transmission ratio and expand the drive wheel. The role of torque and speed. With the development of modern technology, the gearbox has also been upgraded, and the control has become more and more convenient. At present, gasoline engines are widely used in automobiles, and their torque and speed ranges are small, which cannot meet the requirements of traction and driving speed under various working conditions. Gearbox...
