[0002] Automobile engine is a device that provides power for automobiles. It is the core component of automobiles and determines the power, economy, stability and environmental protection of automobiles. Gears are an important part of automobile engines. Gears are wheel-shaped mechanical parts that transmit torque through the meshing of teeth. Gears can achieve functions such as changing speed and torque, changing movement direction and changing movement form by transmitting with other tooth-shaped mechanical parts.

[0003] The existing gear processing and grinding devices are mainly used to grind the tooth grooves and outer edges of the gears. During the gear production process, in order to improve the quality of the gears, the upper and lower sides of the gears should be comprehensively and evenly polished. Traditional gear grinding and polishing equipment is difficult to polish the upper and lower sides of gears of different thicknesses, which will affect the appearance and quality of the gear products.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 5 In the embodiment of the utility model, a grinding and polishing device for automobile engine gear processing includes a dustproof shell 100, a driving motor 201 is fixedly connected to the inner bottom wall of the dustproof shell 100, a turntable 203 is fixedly connected to the output end of the driving motor 201, a toggle rod 204 is fixedly connected to the turntable 203, a hexagonal disk 205 is arranged on one side of the turntable 203, a rotating shaft 207 is fixedly connected to the center position of the hexagonal disk 205, a bearing frame 208 is rotatably connected to the bottom end of the rotating shaft 207, the bearing frame 208 is fixedly connected to the dustproof shell 100, a driving shaft 202 is fixedly connected to the top of the output end of the driving motor 201, two sleeves 302 are slidably sleeved on the driving shaft 202, and a polishing sheet 301 is fixedly connected to the opposite ends of the two sleeves 302; six driving grooves 206 are equidistantly arranged in an annular shape in the hexagonal disk 205, and the toggle rod 204 is slidably connected to the driving groove 206.

[0023] Specifically, the output end of the driving motor 201 can drive the driving shaft 202 to rotate, and the sleeve 302 sleeved on the outside of the driving shaft 202 can drive the two polishing plates 301 to rotate at the same time, so that the two polishing plates 301 can polish and grind the top and bottom surfaces of the automobile gears. The output end can also drive the turntable 203 to rotate, thereby driving the toggle rod 204 to intermittently slide in the driving groove 206 on the hexagonal plate 205. When the toggle rod 204 slides in the driving groove 206, it can drive the hexagonal plate 205 and the rotating shaft 207 to rotate sixty degrees, and correspondingly drive the automobile gear to rotate sixty degrees.
