Description

Technical Field

[0001] The utility model relates to the technical field of tappet processing, in particular to a mechanical tappet end surface processing device. Background Art

[0002] When processing the existing mechanical lifters, especially when processing the end faces of the mechanical lifters, the mechanical lifters need to be fixed to avoid the mechanical lifters from tilting due to uneven force during the processing of the end faces of the mechanical lifters. However, although the existing mechanical lifters can be fixed during processing, the existing clamping mechanism cannot clamp and fix mechanical lifters of different thicknesses. Due to the curved edges of the mechanical lifters, the existing clamping mechanism sets the clamping position to match the curved plate in order to fasten and clamp the mechanical lifters, resulting in different curved edges for lifters of different thicknesses. Therefore, a mechanical lifter end face processing device is needed to solve the above problem. Utility Model Content

[0003] The purpose of the present invention is to address the shortcomings of the prior art. During machining of existing mechanical tappets, particularly during machining of their end faces, the tappets need to be fixed to prevent uneven force on the tappets and resulting in tilting during machining. However, while the existing tappets can be fixed during machining, the existing clamping mechanisms are unable to clamp and secure tappets of varying thicknesses. Due to the curved edges of the tappets, the existing clamping mechanisms require that the clamping locations be adapted to the curved plates in order to securely clamp the tappets. Consequently, the curved edges of tappets of varying thicknesses are adapted to different curved edges. Therefore, a device for machining the end faces of mechanical tappets is provided.

[0005] As a preferred embodiment, three telescopic rods are fixedly connected to the inner wall of the fixing ring, one end of the telescopic rod is fixedly connected to a connecting plate, and one side of the connecting plate is fixedly connected to one side of the splint.

[0006] As a preferred embodiment, a spring is provided on the outer surface of the telescopic rod, one end of the spring is fixedly connected to the inner wall of the fixing ring, and the other end of the spring is fixedly connected to one side of the connecting plate.

[0007] As a preferred embodiment, two rotation grooves are provided on one side of the splint, and the inner walls of the rotation grooves are rotatably connected to rotation rods.

[0008] As a preferred embodiment, a rotating hole is opened on one side of the cover plate, and the inner walls of the two rotating holes are rotatably connected to shaft rods, one side of the cover plate is fixedly connected to a motor, the output end of the motor is fixedly connected to a first gear, the outer surface of the shaft rod is fixedly sleeved with a second gear, one end of the rotating tube is fixedly connected to a third gear, the inner wall of the third gear is rotatably connected to the outer surface of the rotating tube, and both ends of the shaft rod are fixedly connected to fourth gears.

[0009] As a preferred embodiment, the first gear and the second gear are meshed and connected, and the third gear and the fourth gear are meshed and connected.

[0010] Compared with the prior art, the advantages and positive effects of the present invention are: the spring can drive the connecting plate to restore, and then the connecting plate can drive the splint to restore, and then when the arc plate is moving, the splint can slide in the sliding hole of the limit ring, thereby avoiding the splint remaining on the inner wall of the limit ring, and preventing the splint from affecting the mechanical push rod from sliding inside the limit ring and the rotating tube, and the motor can provide driving force, and the first gear and the second gear can drive the shaft to rotate, and the rotation of the shaft can drive the fourth gear to rotate through the third gear, thereby driving the rotating ring to rotate through the rotating sleeve, thereby driving the arc plate to clamp the splint, and the rotating rod can reduce the friction loss between the splint and the arc plate, thereby increasing the service life of the equipment.

[0020] Through the above embodiment, the limiting ring 16 is located inside the rotating ring 12. The inner wall diameter of the limiting ring 16 is the same as the diameter of the rotating tube 4, so that the mechanical tappet can achieve a positioning effect. The rotating ring 12 drives the arc plate 13 to squeeze the clamping plate 17, which in turn drives the clamping plate 17 to clamp the mechanical tappet, thereby clamping and fixing the mechanical tappet and increasing the structural stability of the device.

[0021] Three telescopic rods 20 are fixedly connected to the inner wall of the fixing ring 15. One end of the telescopic rod 20 is fixedly connected to a connecting plate 19. One side of the connecting plate 19 is fixedly connected to one side of the clamping plate 17.

[0022] A spring 21 is provided on the outer surface of the telescopic rod 20, one end of the spring 21 is fixedly connected to the inner wall of the fixing ring 15, and the other end of the spring 21 is fixedly connected to one side of the connecting plate 19;

[0023] According to the above embodiment, the spring 21 can drive the connecting plate 19 to restore, and then the connecting plate 19 can drive the clamping plate 17 to restore. Then, when the arc-shaped plate 13 moves, the clamping plate 17 can slide in the sliding hole of the limiting ring 16, thereby preventing the clamping plate 17 from remaining on the inner wall of the limiting ring 16 and preventing the clamping plate 17 from affecting the sliding of the mechanical tappet inside the limiting ring 16 and the rotating tube 4.

[0024] Two rotation grooves are formed on one side of the clamping plate 17 , and the inner walls of the rotation grooves are rotatably connected to the rotation rods 18 .

[0025] A rotating hole is opened on one side of the cover plate 3, and the inner walls of the two rotating holes are rotatably connected to the shaft rods 5. A motor 6 is fixedly connected to one side of one of the cover plates 3, and the output end of the motor 6 is fixedly connected to the first gear 7. The outer surface of the shaft rod 5 is fixedly sleeved with a second gear 8. One end of the rotating tube 4 is fixedly connected to the third gear 10. The inner wall of the third gear 10 is rotatably connected to the outer surface of the rotating tube 4. The two ends of the shaft rod 5 are fixedly connected to the fourth gear 11.

[0026] The first gear 7 and the second gear 8 are meshed and connected, and the third gear 10 and the fourth gear 11 are meshed and connected;

[0027] Through the above embodiment, the motor 6 can provide driving force, and the first gear 7 and the second gear 8 can drive the shaft 5 to rotate, and the rotation of the shaft 5 can drive the fourth gear 11 to rotate through the third gear 10, so that the rotating ring 12 can be driven to rotate through the rotating sleeve 9, thereby driving the arc plate 13 to clamp the clamping plate 17, and the rotating rod 18 can reduce the friction loss between the clamping plate 17 and the arc plate 13, thereby increasing the service life of the equipment.

[0028] Working principle:

[0029] like Figure 1-4As shown, in use, the mechanical push rod passes through the limit ring 16 and enters the interior of the rotating tube 4, the motor 6 drives the first gear 7 to rotate, the first gear 7 rotates to drive the second gear 8 to rotate, the second gear 8 rotates to drive the shaft rod 5 to rotate, the shaft rod 5 rotates to drive the fourth gear 11 to rotate, the fourth gear 11 rotates to drive the third gear 10 to rotate, the third gear 10 rotates to drive the rotating sleeve 9 to rotate, the rotating sleeve 9 rotates to drive the rotating ring 12 to rotate, the rotating ring 12 rotates to drive the arc plate 13 to rotate, the arc plate 13 rotates to squeeze and clamp the limiting ring 16 of the splint 17, thereby clamping and fixing the mechanical push rod, the motor 6 drives the first gear 7 to rotate in the opposite direction to the above-mentioned direction to drive the arc plate 13 to rotate. At this time, the arc plate 13 is separated from the rotating rod 18 on the splint 17. At this time, the spring 21 contracts to drive the connecting plate 19 to move, and the connecting plate 19 moves to drive the splint 17 to move, so that the rotating rod 18 on the splint 17 can contact the arc plate 13. At this time, the mechanical push rod after processing can be taken out.
