Grinding device for producing shaft type part by using round steel

Abstract

The invention discloses a grinding device for producing a shaft type part by using round steel. The grinding device comprises a pedestal, a main machine box, a three-jaw chuck, a bearing seat, a screwrod and a grinding device part; the main machine box is connected with the pedestal; the three-jaw chuck is rotationally connected with the main machine box; the bearing seat is connected with the pedestal; one end of the screw rod is rotationally connected with the bottom of the main machine box; the other end of the screw rod penetrates through the bearing seat and is rotationally connected with the bearing seat; the grinding device is connected with the screw rod through a screw pair; and the grinding device part consists of a slider, a side frame plate, an electric push rod, a push block,a cushion block, a pressing block and abrasive paper. The grinding device disclosed by the invention realizes direct grinding of the shaft type part after the shaft type part is machined on a machinetool, prevents insecurity caused by manually holding the abrasive paper to implement grinding operation, and also reduces the labor intensity of a worker.

Description

technical field [0001] The invention belongs to the technical field of parts grinding devices, in particular, the invention relates to a grinding device for producing shaft parts from round steel. Background technique [0002] During the machining process of shaft parts, different shaft sections have different roughness requirements. Generally, shaft sections with small roughness need to be polished after machining. The traditional grinding method is that the processed shaft is lathe The three-jaw chuck is clamped, and then the worker holds a strip of sandpaper around the shaft, and tightens the sandpaper, then starts the lathe, rotates the shaft, and then grinds the shaft. This operation method, because the distance between workers The lathe is very close and the sandpaper is tightened by hand. The high-speed rotation of the lathe poses a threat to the safety of workers and increases the labor intensity of workers. Contents of the invention [0003] The invention provide...

[0002] During the mechanical processing of shaft parts, different shaft sections have different roughness requirements. Generally, shaft sections with small roughness need to be polished after machining. The traditional grinding method is that the processed shaft is machined by a lathe. The three-jaw chuck is clamped, and then the worker holds a strip of sandpaper around the shaft, and tightens the sandpaper, then starts the lathe, rotates the shaft, and then grinds the shaft. This method of operation, because the distance between workers The lathe is very close and the sandpaper is tightened by hand. The high-speed rotation of the lathe poses a threat to the safety of workers and increases the labor intensity of workers.
