Problems solved by technology

[0002] Our country is a big country in the use of bearings. The production of needle rollers in bearings directly affects the accuracy of bearings. At present, the rough grinding of needle rollers is mostly done by putting the needle rollers to be processed into the drum for rough grinding, but it is difficult to remove them after rough grinding. Grinding and needle rollers are separated, plus there are some protective oils such as lubricating oil on the needle rollers, and the grinding is easier to stick to the needle rollers. Therefore, a rough needle roller grinding device is proposed, which can The grinding and needle rollers are separated by means of ventilation, and a dust collection sleeve is provided to store grinding dust to prevent pollution, which greatly improves production efficiency and greatly reduces labor intensity

Embodiment 1

[0023] A needle rough grinding device, comprising a cylinder 2 with an open head end and a drive gear 22 disposed at the tail end of the cylinder 2, characterized in that a dust collection sleeve 1 is provided outside the cylinder 2, and on the side wall of the cylinder 2 An ash discharge hole 13 is provided, and the ash discharge hole 13 runs through the cylinder wall of the drum 2 and communicates with the inner cavity of the dust collection sleeve 1 , and a bucket cover 21 is provided at the opening of the head end of the drum 2 . The design of the ash discharge hole 13 and the dust collection sleeve 1 enables the debris generated during the coarse grinding process to be separated from the needle roller, reducing the buffering effect of the debris during the coarse grinding process and improving the efficiency of the coarse grinding.

[0024] The dust collection sleeve 1 is installed on the bracket 34 , and the drum 2 is rotatably connected with the dust collection sleeve 1 ...

Embodiment 2

[0032] An operation method of the above-mentioned needle rough grinding device, characterized in that the steps are as follows:

[0033] Step 1. Adjust the lifting actuator 32 so that the head opening of the drum 2 is inclined upward, open the barrel cover 21 and fill in the needle roller and abrasive, and then close the barrel cover 21;

[0034] Step 2, turn on the blower 4, and start the motor to drive the drum 2 to rotate through the drive gear 22;

[0035] Step 3, while keeping the drum 2 rotating, adjust the lifting actuator 32 so that the inclination angle of the drum 2 is constantly changing;

[0036] Step 4. After the coarse grinding is finished, close the price-raising actuator and the motor to stop the drum 2 from rotating, keep the blower 4 in working condition, and open the ash discharge port 12 to discharge debris and dust;

[0037] Step 5, turn off the blower 4, adjust the lifting actuator 32 to make the head opening of the drum 2 tilt downward, open the barrel ...

Abstract

The invention discloses a roller pin coarse grinding device. The device comprises a roller and a driving gear arranged at the tail end of the roller, wherein the head end of the roller is opened. Thedevice is characterized in that a dust collection sleeve is arranged on the outer side of the roller, dust exhaust holes are formed in the side wall of the roller and penetrate through the roller wallof the roller to communicate with an inner cavity of the dust collection sleeve, a barrel cover is arranged in an opening of the head end of the roller, and an adjusting platform, an air blower and the like are further arranged. Compared with the prior art, the roller pin coarse grinding device has the following advantages that fragments produced in the coarse grinding process can be separated from roller pins, the buffering effect of the fragments in the coarse grinding process is reduced, and the coarse grinding efficiency is improved; through an air supply pipe, airflow in the roller penetrates through the dust exhaust holes to increase the dust exhaust speed, heat is taken away, and the operating safety is improved; by arranging a vibrator, dust is fast exhausted with the aid of the vibrator, and frequent cleaning is avoided; and feeding and discharging are convenient, the coarse grinding process is uniform, and the product quality is improved.
