One end of the transmission shaft 2.11 far away from the screw rod 2.1 is fixedly connected with a dial hand wheel 6. The other side of the deflector rod 9 relative to the cylinder 10 is provided with a thread adjusting pin 11 which is vertical to the deflector rod 9 and is used for adjusting the maximum stroke of the deflector rod 9 pushed by the cylinder 10, thereby controlling the single feeding amount of the grinding wheel 5 and facilitating the adjustment of the feeding precision. A grinding wheel shield 12 is arranged outside the grinding wheel 5, and a mounting seat shield 13 is arranged outside the mounting seat.

The utility model discloses an embodiment is:

firstly, will the utility model discloses install by transporting the transmission band of treating the work piece of polishing, adjusted the utility model discloses an installation angle makes the lead screw 2.1 among the lead screw slide rail mechanism 2 and the work piece on treat that the plane of polishing is perpendicular.

During polishing operation, when a workpiece passes through the grinding wheel 5, the surface of the workpiece is in contact with the grinding wheel 5, and polishing is achieved. When the grinding wheel 5 is abraded and the radius is reduced, the feeding mechanism works to feed the grinding wheel 5 to the vertical direction of the surface of the workpiece to be polished, and the workpiece on the assembly line is continuously and automatically polished.

The working principle of the feeding mechanism is as follows; the control module controls the cylinder 10 to extend out to push the deflector rod 9, the deflector rod 9 drives the first bearing seat 7 to rotate, and then the outer ring of the first one-way bearing 7.1 is driven to rotate, the extending direction of the cylinder 10 is opposite to the rolling direction of the outer ring of the first one-way bearing 7.1, so that the outer ring of the first one-way bearing 7.1 drives the inner ring to rotate at the moment, the screw 2.1 is driven to rotate through the transmission shaft 2.1, and the screw 2.1 rotates to drive the driving motor 4 and the grinding wheel 5 which are installed on the screw slide rail mechanism 2 to feed in the vertical direction of the surface of a grinding workpiece. After the cylinder 10 retracts, the deflector rod 9 is retracted by the spring 9.1 to be pulled back to reset, when the deflector rod is transmitted to the 7.1 outer ring of the one-way bearing I, the 7.1 inner ring of the one-way bearing I does not synchronously rotate along with the outer ring, and the transmission is stopped. At this time, the grinding wheel 5 completes one feed. The feeding amount of the grinding wheel 5 can be observed in real time through the indication of the dial plate on the dial plate hand wheel 6.

The function of the one-way bearing II 8.1 in the working cycle is to ensure that the screw rod 2.1 cannot rotate, thereby ensuring the stable feeding amount. During the reset process of the shift lever 9, the inner ring of the one-way bearing one 7 may drive the screw 2.1 to rotate uncontrollably under slight friction with the outer ring. The mounting direction of the one-way bearing II 8.1 is the same as that of the one-way bearing I7.1, so that when the grinding wheel 5 is fed, the transmission shaft 2.11 rotates along with the inner ring of the one-way bearing I7.1, and the inner ring of the one-way bearing II 8.1 can synchronously rotate along with the transmission shaft 2.11; when the shift lever 9 is reset, the outer ring of the one-way bearing II 8.1 prevents the inner ring from rotating, so that the lead screw 2.1 is prevented from rotating.

After a period of time, the grinding wheel 5 wears to the point where it needs to be replaced. After the machine is stopped, the threaded pins on the first bearing seat 7 and the second bearing seat 8 are unscrewed, and the dial hand wheel 6 is rotated to enable the screw rod 2.1 to rotate reversely in the feeding direction until the grinding wheel 5 resets. Then, the grinding wheel is replaced with a new one, and the threaded pins on the first bearing seat 7 and the second bearing seat 8 are screwed again. And finishing the replacement.

The control module can control the extending times of the cylinder 10 according to the number of the workpieces passing through the counter, the conveying belt conveying meter number recorded by the meter, or the grinding wheel radius measured by the infrared distance meter, so that the feeding amount is controlled in real time. In this embodiment, the number of workpieces passing through is recorded by a counter in a production line. The screw thread adjusting pin 11 can limit the deflector rod 9 and control the maximum stroke of the deflector rod pushed by the air cylinder 10, thereby controlling the feeding amount of single feeding, and the adjustment of the screw thread adjusting pin 11 can realize the control of the feeding precision.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
