High-precision side edge polishing mechanism of gear for gearbox

Abstract

The invention relates to the technical field of polishing mechanisms and discloses a high-precision side edge polishing mechanism of a gear for a gearbox. The high-precision side edge polishing mechanism of the gear for the gearbox comprises an operation platform. A moving plate is connected in a sleeved manner in an inner cavity formed in the top of the operation platform. The front side and theback side of the inner wall of the moving plate are movably connected through two rolling shafts. The high-precision side edge polishing mechanism of the gear for the gearbox solves the problem that an existing high-precision polishing mechanism of the gear for the gearbox is inconvenient to use; through the improvement on the moving plate and application of balls, the moving plate can be flexiblypushed left and right, and therefore after clamping, the two sides of the gear can be polished sequentially; the rolling shafts enable an operator to conveniently move a clamping seat, so that the polishing operation is convenient; through the improvement on the moving platform, the four groups of squeezing springs can keep the sliding block stable in the middle of the inner cavity of a moving groove, due to the use of balls, the movement flexibility of the moving platform can be improved, and therefore it is guaranteed that the moving platform moves back and forth; and in this way, completepolishing of the side edges of the gear is achieved, and the gear polishing efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of grinding mechanisms, in particular to a high-precision gear side grinding mechanism for gearboxes. Background technique [0002] The gearbox mainly refers to the gearbox of the car, which is divided into manual and automatic. The manual gearbox is mainly composed of gears and shafts, which generate variable speed and torque through different gear combinations; while the automatic transmission AT is hydraulically changed. Composed of torque device, planetary gear, hydraulic pitch system and hydraulic control system. Through the combination of hydraulic power transmission and gears to achieve variable torque. [0003] After the gearbox gear is produced, in order to ensure its aesthetics and flexibility in use, the gear is generally polished very finely. The common grinding mechanism needs to be polished on both sides when the gear is polished. This requires a flanging operation. This makes the grinding efficienc...

Problems solved by technology

[0003] After the gearbox gear is produced, in order to ensure its aesthetics and flexibility in use, the gear is generally polished very finely. When the common grinding mechanism is grinding the gear, it needs to grind both sides separately, which requires flanging operation. It makes the grinding efficiency lower, and the side-changing operation affects the grinding efficiency. In addition, the gear is not fixed firmly, which is inconvenient for the operator to operate and affects the grinding effect.
