[0033] As shown in Figure 1 , Figure 3 andFigure 4 As shown, the workbench is fixedly installed on the movable base 1. A handle 4 is fixedly provided on one side of the workbench to facilitate the adjustment of the workbench position and the movement of the grease application device. A power distribution box 2 is provided on the workbench. The power distribution box 2 serves as the electrical control center of the external oil filter uniform grease application device for axles. It is responsible for distributing power to each motor in the device and controlling their coordinated operation. The power distribution box 2 includes circuit breakers, contactors, relays, and PLCs (programmable logic controllers) to ensure the stable operation of the electrical system and to control each motor and sensor.

[0034] The grease source includes an oil tank, an oil pipe 8, and an oil pump 7. The oil tank is located inside the workbench and is used for storing grease. The oil tank is connected to the oil pipe 8, and a nozzle is installed at the end of the oil pipe 8 and fixedly installed inside the oil pan 10. The nozzle is located on one side of the oil applicator 9 for spraying grease onto the oil applicator 9.

[0037] like Figure 2 As shown, the drive mechanism includes a friction wheel 12 and a tray 19. The friction wheel 12 is fixedly installed on the tray 19 by a threaded connection. The friction wheel 12 and the tray 19 are coaxially arranged. The tray 19 is fixedly installed on the output end of the first motor 18. The friction wheel 12 is arranged vertically and is located above the oiler 9. The axis of the friction wheel 12 is parallel to the axis of the oiler 9. The friction wheel 12 is used to abut against the fixed end of the oil filter 21, thereby driving the oil filter 21 to rotate around the axis.

[0038] The clamping mechanism comprises a clamping cover 13, a guide rod 14, a guide rod support 15, a pressing plate 16 and a transverse driving unit 17. The transverse driving unit 17 is fixedly installed on the mounting seat 3 and is in the structure of a transverse linear motor, an electric telescopic rod, a telescopic oil cylinder or the like. The telescopic end of the transverse driving unit 17 is fixedly connected with the guide rod 14. The guide rod support 15 is fixedly arranged on the mounting seat 3. The guide rod 14 transversely penetrates through the guide rod support 15. The end of the guide rod 14 away from the transverse driving unit 17 is threadedly connected with the pressing plate 16. The clamping cover 13 is rotatably arranged on the pressing plate 16 through bearings or the like. The transverse driving unit 17 controls the transverse horizontal movement of the pressing plate 16 and the clamping cover 13 through the guide rod 14. The clamping cover 13 is vertically arranged and can contact one end of the oil filter 21 and transversely clamp and fix the oil filter 21 between the friction wheel 12 and the clamping cover 13.

[0039] In the embodiment, the clamping cover 13 is in the hollow cover structure. It can be understood that, in other embodiments, the clamping cover 13 can also be arranged in other structural forms, such as a plate structure, a block structure or the like. The specific structural form is not limited here too much, as long as the effective abutment between the clamping cover 13 and the end of the oil filter 21 can be ensured.

[0040] The central axis of the clamping cover 13 is collinear with the central axis of the friction wheel 12. The clamping cover 13 can rotate around the shaft, so that the oil filter 21 is transversely clamped and fixed between the friction wheel 12 and the clamping cover 13 by the clamping cover 13, and meanwhile, the rotation of the friction wheel 12 around the shaft can drive the oil filter 21 to rotate, so as to realize the uniform smearing of the O-shaped sealing ring with the lubricating grease. The cooperation between the guide rod 14 and the guide rod support 15 ensures the linear motion track of the clamping cover 13 and avoids the deviation of the clamping force (which can also be understood as the clamping force) direction.

[0041] Since the rotation directions of the rotors of the first motor 18 and the second motor 20 are opposite, the rotation direction of the oil filter 21 and the oil applicator 9 is opposite, the lubricating grease can be more uniformly distributed on the friction surface, which helps to optimize the utilization of the lubricating grease, avoids the situation of insufficient lubrication or excessive lubrication in some areas, and thus reduces the waste of the lubricating grease and reduces the cost.

[0042] In order to improve the stability of the oil filter 21 during the greasing process, a supporting mechanism is also provided, which is located below the top cover 13 and the friction wheel 12, and is used to assist in supporting the oil filter 21. The supporting mechanism includes two sets of oppositely arranged supporting roller groups, each of which includes two supporting rollers 11 arranged side by side. Specifically, one set of supporting roller groups is rotatably arranged on the mounting seat 3, and the other set of supporting roller groups is rotatably arranged on the motor box 6. Specifically, two supporting rollers 11 are rotatably arranged on the mounting seat 3, which are oppositely distributed on both sides below the top cover 13. Similarly, two supporting rollers 11 are rotatably arranged on the motor box 6, which are oppositely distributed on both sides below the friction wheel 12, thereby assisting in supporting and positioning the oil filter 21, so as to limit the freedom of the oil filter 21 except for rotating around its own axis, and ensure the stability of the rotation of the oil filter 21 around the shaft.

[0043] Specifically, the working principle is as follows:

[0044] Before the oiling operation starts, the oil filter 21 is placed on the greasing device, so that the cylinder wall of the oil filter 21 is in contact with the top of the two supporting rollers 11 on the side of the tightening mechanism, the flange plane of the fixed end is in contact with the surface of the friction wheel 12, the cylindrical surface of the fixed end is in contact with the top of the two supporting rollers 11 on the side of the driving mechanism, the lowest part of the O-shaped sealing ring of the oil filter 21 is embedded in the grease storage groove of the oil applicator 9, the surface of the lowest part of the O-shaped sealing ring is in contact with the lubricating grease in the grease storage groove, and the positioning of the oil filter 21 is completed, so that the axis of the oil filter 21 is collinear with the central axis of the friction wheel 12.

[0045] Then, the horizontal movement driving unit 17 is started, the top cover 13 pushes the tightened oil filter 21, and the axis of the friction wheel 12, the top cover 13 and the oil filter 21 is ensured to be collinear during the tightening process. The first motor 18 and the second motor 20 are started to drive the oil filter 21 and the oil applicator 9 to rotate around the central axis, respectively. The oil pump 7 injects the lubricating grease into the grease storage groove of the oil applicator 9 through the oil delivery pipe 8 and the nozzle at the end thereof. The oil applicator 9 applies the lubricating grease to the O-shaped sealing ring of the oil filter 21 in contact with it. After the greasing is completed, the top cover 13 returns to the initial position, and the oil filter 21 is removed to prepare for the next working cycle.

[0046] The oil filter 21 is transversely clamped and positioned by the cooperation of the top cover 13 and the friction wheel 12 and can rotate around the shaft, and the oil filter is provided with a grease storage groove on the outer edge of the oil applicator 9 along the ring direction, and the O-shaped sealing ring on the oil filter is embedded into the lowest position of the grease storage groove, and the grease source supplies lubricating grease into the grease storage groove through the oil delivery pipe 8, and the arrangement of the oil applicator 9 and the grease storage groove not only does not mix impurities, but also can accurately control the lubricating grease application area, avoids the influence of the thread of the oil filter 21 on the tightening torque due to the adhesion of lubricating grease, and the application of the grease relies on the rotation of the oil applicator and the O-shaped sealing ring, the application amount of the lubricating grease can be uniformly controlled, and the lubricating grease can also be recycled, the oil pan 10 is used for receiving the dropped lubricating grease, avoids the pollution of the workbench and plays the role of recycling the excess lubricating grease, and in addition, the arrangement of the oil delivery pump 7 can realize the quantitative pumping of the lubricating grease, effectively controls the application amount of the lubricating grease and assists in improving the application uniformity.
