Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a driving shaft grinding equipment. Background Art

[0002] The tooling drive shaft grinder is a widely used component in the manufacturing industry. Sometimes, due to the constraints of processing equipment or processing costs, many companies directly choose to entrust external manufacturers to process. However, in the process of entrusting external processing, the processing quality cannot be controlled by themselves, resulting in the situation that the actual size often exceeds the size marked on the drawing, that is, the processing accuracy does not meet the requirements. If the accuracy error is large, it will generally be returned to the external manufacturer for repair; if the size of the exceeding part is not very large, generally 0.01-0.1mm, in this case, only the size that exceeds the range needs to be properly polished for normal use, that is, the position that does not meet the size can meet the requirements on the drawing and can be smoothly installed on the tooling or bearing.

[0003] At present, this kind of grinding operation is usually performed by directly grinding the outer wall of the drive shaft grinder with sandpaper by hand. This manual grinding method is not only time-consuming and laborious, but also the degree of force applied by the hand is usually difficult to accurately control, resulting in uneven grinding of the outer wall of the drive shaft grinder, and ultimately unable to be smoothly installed on the tooling or bearing.

[0004] After searching the existing Chinese patents: a drive shaft grinder (publication number: CN218363695U), including a base, one end of the base is provided with a vertical baffle, the other end is connected to a clamping mechanism for clamping one end of the drive shaft, the vertical baffle is provided with a positioning part, the other end of the drive shaft is rotatably positioned on the positioning part along its axis; the base is provided with a sandpaper fixing frame that can move between the vertical baffle and the clamping mechanism, and when the drive shaft is limited between the positioning part and the clamping mechanism, the sandpaper on the sandpaper fixing frame is in contact with the outer wall of the drive shaft; the base is also provided with a driving mechanism for driving the clamping mechanism to rotate to drive the drive shaft to rotate, so as to achieve friction grinding of its outer wall on the sandpaper surface. This application provides a drive shaft grinder that can stably limit the drive shaft, ensure accurate control of the grinding position, improve grinding accuracy, and use a mechanical structure to perform action grinding, replacing the original manual grinding, saving labor and improving grinding efficiency.

[0005] Although the above-mentioned Chinese patent is able to stably limit the drive shaft, ensure accurate control of the grinding position, improve grinding accuracy, and use a mechanical structure to perform action grinding, replacing the original manual grinding, saving labor and improving grinding efficiency; however, the device is not convenient for replacing sandpaper, and the consumption of sandpaper is relatively large during actual grinding operations. The device lacks a structure for storing and fixing sandpaper, which is not convenient for users to operate for a long time.
