Description

Technical Field

[0001] The utility model relates to the technical field of steering bracket processing, in particular to a steering bracket grinding device. Background Art

[0002] The steering system in a vehicle has the function of steering the vehicle according to the driver's intention during driving. The steering gear, as an important component of the vehicle steering system, is used to increase the force transmitted from the steering wheel to the steering knuckle and change the direction of force transmission. The steering gear is generally fixed to the subframe through a steering bracket. The steering bracket needs to be polished after production, so it is necessary to use a steering bracket polishing equipment to polish the steering bracket.

[0003] After searching, a steering bracket grinding device with the authorization publication number CN220330934U includes a grinding frame, a motor is arranged inside the grinding frame, a first pulley is fixedly connected to the output shaft of the motor, a second pulley is fixedly sleeved on the outer surface of the bidirectional screw, a transmission belt is connected between the first pulley and the second pulley, a chuck is coaxially fixedly connected to the outer surface of the first pulley, a driving block is threadedly sleeved on the outer surface of the bidirectional screw, and a workpiece with a rotatable columnar structure is ground under the abutment of a grinding plate, and the driving block drives the grinding plate on the surface of the workpiece The surface moves up and down, thereby ensuring that the device can grind the workpiece in all directions and at the same time ensuring that the degree of grinding in various places of the workpiece is the same. By rotating the handle, the threaded block drives the grinding plate to lean against the workpiece. The position of the grinding plate can be adjusted according to the thickness of the workpiece, thereby improving the practicability of the device and also adjusting the degree of grinding.
