Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a tubular parts grinding device for mechanical processing. Background Art

[0002] The tubular parts grinding device is a device that uses automatic control and advanced grinding technology to grind tubular parts. It can significantly improve the efficiency of processing and grinding, and can also ensure the high quality of the tubular parts after grinding.

[0003] A Chinese patent discloses a grinding device for mechanical processing (Announcement No. CN 212470778U), which includes a box, a guide rod, a fixing device and two forward and reverse motors. Guide rods are welded and fixed on the inner walls of both sides of the box, and mounting grooves are provided in the guide rods. A forward and reverse motor is fixed on the right outer wall of the box by bolts, and an adjusting screw is welded and fixed on the output end of the forward and reverse motor. A guide plate is threadedly connected on the outer wall of the left half of the adjusting screw, and a rotating motor is fixed on the left outer wall of the guide plate by bolts. A rotating shaft is welded and fixed on the output end of the rotating motor, and a fixing device is welded and fixed on the right end face of the rotating shaft.

However, the patent adopts a method of manually tightening the fixing device to fix the two ends of the tubular part, which not only increases the labor intensity of the operator, but also fails to meet the needs of efficient production. At the same time, if the operator exerts uneven or excessive force, it is likely to cause uneven extrusion of the two ends of the tubular part, thereby causing deformation and affecting the function and performance of the part.
