Technical Field

[0001] The utility model relates to the technical field of wheel hub grease injection machines, in particular to a movable multi-station wheel hub grease injection machine. Background Art

[0002] Grease can form a lubricating film on the contact surface of the wheel hub, reducing direct contact between metals, thereby reducing friction and wear, which helps to extend the service life of the wheel hub. Therefore, the wheel hub needs to be greased before and after manufacturing and use.

[0003] After searching, the patent document with announcement number CN221035177U discloses an automatic wheel hub grease injection machine. The grease injection machine is equipped with a fixed ejection device. Under the action of the circular plate, the large circular groove and the small circular groove are coordinated so that the ejection rod and the ejection block can eject the greased wheel hub, thereby effectively avoiding the grease splashing caused by constant shaking during the picking process, thereby reducing the cleaning cost. Under the action of the threaded extrusion rod, the wheel hub placed on the operating disc can be limited, thereby avoiding the shaking of the wheel hub during the grease injection process and increasing stability.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] The embodiment of the utility model discloses a movable multi-station wheel hub grease injection machine.

[0032] Example 1

[0033] The utility model provides Figure 1-5 The shown movable multi-station wheel hub grease injection machine comprises a movable base 1 and a support block 2 fixedly arranged on the top of the movable base 1, universal wheels 27 are fixedly provided at the four corners of the bottom of the movable base 1, a silo 3 is provided inside the support block 2, a feeding port is provided on the top of the silo 3, a sealing plug 25 is embedded in the feeding port, a support frame 4 is fixedly provided on the top of the support block 2, an electric push rod 5 is fixedly provided on the top of the support frame 4, the output shaft of the electric push rod 5 passes through the support frame 4 and is fixedly provided with a cross plate 6, connecting rods 7 are fixedly provided at both ends of the bottom of the cross plate 6, an elastic telescopic rod 8 is fixedly provided at the bottom of the connecting rod 7, and a grease injection cover 9 is fixedly provided through the elastic telescopic rod 8, and two symmetrically arranged positioning rods 26 are fixedly provided on the top of the support block 2;

[0034] A guide tube 10 is fixedly provided on the top of the support block 2, and a feed pipe 11 is connected to the bottom of the guide tube 10. The lower end of the feed pipe 11 is located in the silo 3, and discharge pipes 12 are connected to both sides of the guide tube 10. The upper end of the discharge pipe 12 is fixedly penetrated into the side of the grease injection cover 9, and the pipe walls of the feed pipe 11 and the discharge pipe 12 are fixedly sleeved with a material one-way valve 16.

[0035] Before greasing the wheel hub, the device is moved to the greasing processing area through multiple universal wheels 27, and then the sealing plug 25 is opened, and the greasing raw materials are added to the silo 3 through the feeding port, and the sealing plug 25 is plugged back to ensure that the inside of the silo is sealed. Then, one side pressing is performed first, so that the electric push rod 5 pushes the cross plate 6 to move down and return, so that the guide tube 10 can cooperate with the feed pipe 11 to suck the greasing raw materials inside the silo 3 into the guide tube 10, and then multiple wheel hubs are placed on the top of the support block 2 and positioned by the positioning rod 26. Then the electric push rod 5 moves down again, so that the cross plate 6 moves down the greasing cover 9 through the support rod 7. When the greasing cover 9 is sleeved on the outside of the wheel hub and contacts the top of the support block 3, the elastic telescopic rod 8 can be compressed under the continuous pressure of the cross plate 6. At this time, the greasing raw materials inside the guide tube 10 can be pushed and flow into the greasing cover 9 from the discharge pipes 12 on both sides, so that the greasing raw materials cooperate with the wheel hub to complete the greasing work.

[0036] Example 2

[0037] Example 2 is based on Example 1 in order to enable the grease injection material to stably enter the guide tube 10 and be stably pushed out when the horizontal plate 6 moves back and forth longitudinally. Figure 1 and Figure 4 As shown, the liposuction and fat injection mechanism includes a movable piston 13, which is slidably arranged in the guide tube 10, and a pull plate 14 is fixedly provided on the top, and a vertical plate 15 is fixedly provided on the bottom of the horizontal plate 6. The vertical plate 15 and the pull plate 14 are close to one end and have a pull groove inside, and the two pull grooves are clamped together.

[0038] When the horizontal plate 6 moves downward, under the sliding restriction of the two pulling grooves, the pulling plate 14 can push the vertical plate 15, so that the movable piston 13 moves downward quickly and pushes out the grease injection material inside the guide tube 10. When the horizontal plate 6 moves upward, the movable piston 13 can be pulled. At this time, under the action of the air pressure inside the guide tube 10, the grease injection material inside the silo 3 can be stably sucked into the guide tube 10, so that the grease injection material can be stably circulated and contacted with the wheel hub.

[0039] Example 3

[0040] In order to ensure that the wheel hub can be stably greased in the grease injection cover 9, the embodiment 3 is based on the embodiment 1. Figure 1-3 and Figure 5 As shown, the interior of the grease cover 9 is provided with a plurality of adjusting and clamping mechanisms which are symmetrically arranged in a surrounding manner. The adjusting and clamping mechanisms include an adjusting screw 17, which is rotatably arranged on the side of the grease cover 9, and a slider 18 is threadedly sleeved on the rod wall. The side wall of the slider 18 is fixed with a splint 20 through two symmetrically arranged springs 19. The splint 20 is bent, and two symmetrically arranged guide telescopic rods 21 are fixed between the slider 18 and the inner wall of the grease cover 9. An annular groove is provided on the outer wall of the grease cover 9, and an annular plate 22 is rotatably penetrated inside the annular groove. A bevel gear ring 23 is fixedly provided at the bottom of the annular plate 22. The rod walls of the plurality of adjusting screws 17 are fixedly sleeved with a bevel gear 24, and the bevel gear ring 23 is matched with the bevel gear 24.

[0041] When the wheel hub is located on the top of the support block 3, the annular plate 22 can be rotated in advance according to the specifications of the wheel hub. At this time, the bevel gear ring 23 can drive multiple adjusting screws 17 to rotate at the same time, so that the slider 18 drives the splint 20 to move under the support of the guide telescopic rod 21. When the grease injection cover 9 moves down, through the bending part of the splint 20, multiple splints 20 can be stably sleeved on the outside of the wheel hub, and through the elastic force of the spring 19, the multiple splints 20 can stably clamp the wheel hub, thereby ensuring the stability of the wheel hub when grease is injected.

[0042] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
