Description

Technical Field

[0001] The utility model belongs to the technical field of transmission processing equipment, and in particular relates to a grinding device for a transmission housing. Background Art

[0002] The transmission is an automotive accessory used to change the speed and torque from the engine, and can fix or change the transmission ratio of the output shaft and the input shaft. The gearbox is composed of a speed transmission mechanism and an operating mechanism. Some cars also have a power output mechanism, which can be divided into stepped, stepless and integrated transmissions. It has the functions of realizing reverse driving, interrupting power transmission, changing transmission ratios, etc. The transmission housing needs to be polished in the later stage of processing to remove the burrs on the surface of the transmission housing. The existing polishing devices clamp the transmission housing on the fixture, and then polish the four sides of the transmission housing in turn through the polishing device. However, this method of polishing only one side of the transmission housing at a time is inefficient, and each time the next side is polished, the transmission housing needs to be removed from the fixture for surface polishing, which is inefficient.

[0003] The Chinese utility model patent with publication number CN217750873U discloses a transmission case grinding device, which places the square transmission case between two grinding components through a clamping member, and then starts the grinding belt on the grinding component to rotate, and grinds the two side surfaces of the square transmission case at the same time. After grinding the two side surfaces, the clamping surface of the square transmission case is replaced, and then the remaining two side surfaces of the square transmission case are grinded. The two side surfaces of the square transmission case can be grinded at the same time, thereby improving the grinding efficiency. However, the device still has some other problems. For example, the device can only remove burrs on the surface of the transmission case, but cannot grind away burrs in small gaps. Utility Model Content
