Description

[0002] The piston pin is a part that is usually used in automobiles and mechanical equipment to connect the piston and the connecting rod. It plays an important role in supporting and transmitting power. The manufacturing process of the piston pin has a vital impact on the quality and performance of the entire automobile and mechanical equipment. During the processing of the piston pin, its surface needs to be processed by a grinding device.

[0003] When processing the piston pin surface, the traditional grinding processing device can adjust the distance between the guide wheel and the grinding wheel according to the diameter of the piston pin. However, after adjusting the front and rear distance of the guide wheel, the guide wheel is adjusted by rotating the threaded rod, and the threaded rod is easily loosened by external forces (such as the vibration force generated when the grinding machine is working), resulting in the guide wheel that has been adjusted to a position being easily movable, thereby affecting the surface processing accuracy of the piston pin. In addition, although the traditional grinding processing device is provided with a cutting fluid circulation mechanism, which can spray cutting fluid onto the grinding wheel, the surface of the filter screen in the cutting fluid circulation mechanism is easily blocked by iron filings, affecting the normal delivery of the cutting fluid. In addition, when cleaning the iron filings on the surface of the filter screen, manual cleaning is required, which brings a workload to the staff. Summary of the invention

[0019] Through the cooperation of the external spring of the guide rod, the sliding plate and the lifting plate, the sliding plate is always located at the upper end position inside the rectangular shell without being affected by the downward pulling force, and then cooperates with the lifting plate to further lock and limit the two driving plates and the two locking racks, thereby improving the reliability of the two locking racks during the locking action.

The structure is simple and practical, and no additional motor drive is required when the cleaning mechanism and the clearing mechanism are in operation, thereby reducing the loss of electric energy.

[0022] By setting up the driving component, when the tooth blocks on the opposite sides of the two locking racks are separated from the outer peripheral surface of the locking gear to the left and right, the two locking racks can be moved in opposite directions at the same time by simply stepping down the U-shaped pedal with the foot, so that the tooth blocks on the opposite sides of the two locking racks are separated from the left and right sides of the outer peripheral surface of the locking gear, thereby improving the convenience when operating the distance adjustment mechanism.

[0062] The present invention discloses a method for processing the surface of a piston pin, comprising the following steps: firstly, starting a conveying motor 604, driving a driving pulley, a driven pulley and a sprocket 602 on the left side through the conveying motor 604 to rotate clockwise, and then driving a chain 603 to drive clockwise; then starting a grinding motor 204, driving a driving pulley, a driven pulley, a rotating shaft 201 and a grinding wheel 203 through the grinding motor 204 to rotate; then placing a piston pin on the upper left side of the chain 603, and conveying the piston pin to the right through the chain 603, when the piston pin is conveyed to the front side of the grinding wheel 203 After that, the surface of the piston pin is ground by the rotating grinding wheel 203; during the grinding process of the piston pin, the circulating pump 501 is started to generate suction inside the suction pipe 502 and the filter box 505, so that the cutting fluid inside the collecting box 105 is transported to the inside of the spray head 504, and the cutting fluid is sprayed onto the surface of the piston pin through the spray head 504 to wash away the iron filings generated during the grinding process of the piston pin surface; the ground piston pin is finally transported to the right end of the chain 603 through the chain 603, and finally the ground piston pin is taken down from the upper part of the chain 603.

[0063] The working principle of this embodiment is as follows: when in use, first start the conveying motor 604, and the conveying motor 604 drives the driving pulley, the driven pulley and the sprocket 602 on the left to rotate clockwise, and then drives the chain 603 to drive clockwise, then start the grinding motor 204, and drive the driving pulley, the driven pulley, the rotating shaft 201 and the grinding wheel 203 to rotate through the grinding motor 204, and then place the piston pin on the upper left side of the chain 603, and convey the piston pin to the right through the chain 603. When the piston pin is conveyed to the front side of the grinding wheel 203, the rotating grinding wheel 203 grinds the surface of the piston pin, and then the guide wheel 402 is driven. When adjusting, the U-shaped pedal member 801 is stepped down by the foot, so that the U-shaped pedal member 801 moves downward with the sliding plate 802 and the two lifting plates 803, and then the two driving columns 705 are forced to move in opposite directions with the two driving plates 704 and the two locking racks 703 through the two rectangular openings 804, so that the tooth blocks on the opposite sides of the two locking racks 703 are separated from the left and right sides of the outer circumference of the locking gear 305, and then the threaded rod 304 is rotated to make the sliding seat 303 move forward and backward with the second bearing 404 and the guide wheel 402 under the action of the thread, so that the front and rear distance of the guide wheel 402 is adjusted;

[0064] When the front-to-rear distance of the guide wheel 402 is adjusted, stop stepping on the U-shaped pedal 801. At this time, the two locking racks 703 will lose their pulling force, and then the two locking racks 703 will move in relative directions at the same time under the action of the external spring force of the sliding rod 706, so that the tooth blocks on the opposite sides of the two locking racks 703 are in close contact with the left and right sides of the outer peripheral surface of the locking gear 305 respectively, so that the locking gear 305 and the threaded rod 304 can obtain effective locking and limiting effects, thereby preventing the threaded rod 304 from being easily loosened by external forces.

[0065] During the grinding process of the piston pin, the circulation pump 501 is started to generate suction inside the suction tube 502 and the filter box 505, thereby transporting the cutting fluid inside the liquid collecting tank 105 to the inside of the spray head 504. The cutting fluid is sprayed onto the surface of the piston pin through the spray head 504 to flush the iron filings generated during the grinding process of the piston pin surface. The flushed cutting fluid leaks into the funnel 106 through the leakage hole 103, and then is discharged into the liquid collecting tank 105 through the liquid outlet at the lower end of the funnel 106, thus realizing recycling.

[0066] During the operation of the conveying motor 604, the first bevel gear 605 drives the second bevel gear 9010, the first transmission shaft 903, the third pulley 9011, the second pulley 908, the second transmission shaft 904, the first pulley 907, the fourth pulley 1008, the rotating rod 1006 and the cam 1007 to rotate. When the protrusion of the cam 1007 faces backward, the protrusion of the cam 1007 pushes the moving frame 1005 backward, thereby driving the clearing plate 1001, the clearing needle 1002 and the sliding cylinder 1003 backward. The sliding guide rod 1004 moves, and the outer spring of the sliding guide rod 1004 is compressed. Then, when the protrusion of the cam 1007 faces forward, the moving frame 1005 loses its backward pushing function. Then, the sliding cylinder 1003 moves forward rapidly with the clearing plate 1001 and the clearing needle 1002 under the action of the outer spring of the sliding guide rod 1004. At this time, the clearing needle 1002 is inserted into the mesh of the filter screen plate 506 to push out the iron filings blocked in the mesh of the filter screen plate 506, so as to avoid the blockage of the mesh of the filter screen plate 506.

[0067] During the rotation of the second transmission shaft 904, the circular driving disk 905 is rotated, and then the circular driving disk 905 rotates with the toggle column 906. The rotating toggle column 906 drives the driving block 909 and the sweeping brush 901 to move up and down, thereby sweeping away the iron filings ejected to the front end surface of the filter screen plate 506.
