Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to a wheel hub bearing grease injection machine. Background Technology

[0002] Wheel bearings are crucial components connecting wheels and axles, allowing wheels to rotate smoothly with minimal friction. Their primary functions include load-bearing and providing precise guidance for wheel rotation. Capable of withstanding axial and radial loads, they are vital automotive parts. Before sealing, wheel bearings require the addition of a specific amount of lubricating grease; the amount added is precisely calculated, ensuring that neither too much nor too little is added.

[0003] Currently, the grease injection process for existing wheel hub bearings is usually done manually. The grease is manually filled into a plastic bag, a hole is cut at the end of the bag, and then the grease is squeezed into the internal space of the wheel hub bearing.

[0004] In the above solution, the existing grease injection operation is carried out by manually squeezing the grease into the internal space of the wheel hub bearing bit by bit. Therefore, the grease injection efficiency is very low, the amount of grease injected cannot be well controlled, and the grease cannot be evenly distributed inside the wheel hub bearing. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wheel hub bearing grease injection machine. By providing a grease pressing component, a moving mechanism, a grease injection head, and a three-jaw chuck, it can automatically inject grease into the two grooves of the wheel hub bearing, solving the problem that the prior art requires manual squeezing of grease into the wheel hub bearing grooves, thereby improving grease injection efficiency and allowing precise control of the grease injection amount, so that the grease can be evenly distributed in the wheel hub bearing grooves.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A wheel hub bearing grease injection machine includes a machine body, a grease tank on one side of the machine body, a grease pressure plate inserted inside the grease tank, a grease pressure assembly at the upper end of the grease pressure plate, a support column fixed at the upper end of the machine body, a moving mechanism at the upper end of the support column, the moving mechanism including a lifting assembly and a translating assembly, a grease injection head on the translating assembly, a pressure reducing valve fixed on the side wall of the support column, a grease delivery pipe connected between the pressure reducing valve, the grease pressure plate, and the grease injection head, and a rotatable three-jaw chuck at the upper end of the machine body.

[0008] When grease needs to be injected into both grooves of a wheel bearing, place the wheel bearing on the upper end of a three-jaw chuck and clamp and fix it in place. Then, activate the lifting and translating components to move the end of the grease injection head horizontally and downward into one of the grooves. Next, activate the pressure component to move the pressure plate downward, thereby pressing out the grease from the grease tank. The grease is then forced through the grease delivery pipe and pressure reducing valve, and squeezed out from the end of the grease injection head. Simultaneously, the three-jaw chuck rotates, causing the wheel bearing to rotate as well. This allows for even grease injection into one groove of the wheel bearing. After grease injection, the lifting component moves the end of the grease injection head to the other groove, and the above operation is repeated. This ensures even grease injection into both grooves of the wheel bearing. Under the action of the pressure reducing valve, the amount of grease in the grease delivery pipe can be precisely adjusted, thus effectively controlling the amount of grease injected.

[0009] By incorporating a grease injection assembly, a moving mechanism, a grease injection head, and a three-jaw chuck, grease can be automatically injected into the two grooves of the wheel hub bearing. This solves the problem of existing technologies requiring manual grease injection into the wheel hub bearing grooves, thereby improving grease injection efficiency and allowing for precise control of the grease injection amount, ensuring that the grease is evenly distributed within the wheel hub bearing grooves.

[0010] The utility model is further configured such that: the lifting assembly includes a guide rail fixed on the side wall of the support column, a first slide plate and a second slide plate are slidably connected on the guide rail, a first cylinder is fixed at the upper end of the support column, the output end of the first cylinder passes through the support column and is fixed at the upper end of the first slide plate, a second cylinder is fixed at the upper end of the first slide plate, the output end of the second cylinder passes through the first slide plate and is fixed at the upper end of the second slide plate, and a translation assembly is disposed at the upper end of the second slide plate.

[0011] With the above technical solution, when it is necessary to move the end of the grease injection head into one of the grooves, the first cylinder is activated, which moves the first slide plate downward. The downward movement of the first slide plate moves the second cylinder downward, which in turn moves the second slide plate downward. The downward movement of the second slide plate moves the translation component downward, thereby moving the end of the grease injection head into one of the grooves. When it is necessary to move the end of the grease injection head into another groove, the second cylinder is activated, which moves the second slide plate downward, and simultaneously moves the translation component downward, thereby moving the end of the grease injection head into the other groove.

[0012] The utility model is further configured such that: the translation component includes a slide rail fixed to the upper end of the second slide plate, a slider slidably connected on the slide rail, a grease injection head fixed to the side wall of the slider, a third cylinder fixed to the side wall of the support column, and the output end of the third cylinder fixed to the side wall of the slider.

[0013] With the above technical solution, when it is necessary to move the grease injection head horizontally, the third cylinder is activated to move the slider, thereby moving the grease injection head horizontally.

[0014] The utility model is further configured such that: the grease pressing assembly includes two fourth cylinders disposed on both sides of the grease tank, the same support plate is fixed on the output end of the two fourth cylinders, two connecting rods are symmetrically fixed on the lower end of the support plate, and the grease pressing plate is simultaneously fixed on the lower end of the two connecting rods.

[0015] With the above technical solution, when it is necessary to move the pressure plate downward, two fourth cylinders are activated simultaneously to move the support plate downward. The downward movement of the support plate causes the two connecting rods to move downward, thereby moving the pressure plate downward.

[0016] The utility model is further configured such that: the rotatable three-jaw chuck includes a motor fixed inside the machine body, a disc fixed on the output end of the motor passing through the machine body, and the three-jaw chuck fixed on the upper end of the disc.

[0017] With the above technical solution, when it is necessary to rotate the three-jaw chuck, the motor is started to drive the disc to rotate, thereby driving the three-jaw chuck to rotate.

[0018] The beneficial effects of this utility model are:

[0019] Compared with existing technologies, this invention features a grease injection assembly, a moving mechanism, a grease injection head, and a three-jaw chuck, which automatically injects grease into the two grooves of the wheel hub bearing. This solves the problem that existing technologies require manual grease injection into the wheel hub bearing grooves, thereby improving grease injection efficiency and allowing for precise control of the grease injection amount, ensuring that the grease is evenly distributed within the wheel hub bearing grooves.

[0023] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0024] The following is for reference Figures 1 to 2 This utility model will now be described.

[0025] A wheel hub bearing grease injection machine includes a machine body 1, a grease tank 2 on one side of the machine body 1, a grease pressure plate 3 inserted inside the grease tank 2, a grease pressure assembly at the upper end of the grease pressure plate 3, a support column 4 fixed at the upper end of the machine body 1, a moving mechanism at the upper end of the support column 4, the moving mechanism including a lifting assembly and a translating assembly, a grease injection head 5 on the translating assembly, a pressure reducing valve 6 fixed on the side wall of the support column 4, a grease delivery pipe 7 connecting the pressure reducing valve 6 to the grease pressure plate 3 and the grease injection head 5, and a rotatable three-jaw chuck 8 at the upper end of the machine body 1.

[0026] When grease needs to be injected into the two grooves of the wheel hub bearing, place the wheel hub bearing on the upper end of the three-jaw chuck 8 and clamp and fix the wheel hub bearing with the three-jaw chuck 8. Then, activate the lifting and translating components to move the end of the grease injection head 5 translating and moving downward into one of the grooves. Then, activate the grease pressing component to move the grease pressing plate 3 downward, thereby pressing out the grease in the grease tank 2. The grease is then squeezed out from the end of the grease injection head 5 after passing through the grease delivery pipe 7 and the pressure reducing valve 6. At the same time, the three-jaw chuck 8 is rotated, which in turn causes the wheel hub bearing to rotate, thereby evenly injecting grease into one groove of the wheel hub bearing. After grease injection, the lifting component is used to move the end of the grease injection head 5 to the other groove. The above operation is repeated to evenly inject grease into both grooves of the wheel hub bearing. Under the action of the pressure reducing valve 6, the amount of grease in the grease delivery pipe 7 can be precisely adjusted, thereby effectively controlling the amount of grease injected.

[0027] By incorporating a grease injection assembly, a moving mechanism, a grease injection head 5, and a three-jaw chuck 8, grease can be automatically injected into the two grooves of the wheel hub bearing. This solves the problem of the existing technology requiring manual grease to be squeezed into the wheel hub bearing grooves, thereby improving grease injection efficiency and allowing precise control of the grease injection amount, so that the grease can be evenly distributed in the wheel hub bearing grooves.

[0028] The lifting assembly includes a guide rail fixed to the side wall of the support column 4, a first slide plate 9 and a second slide plate 10 slidably connected on the guide rail, a first cylinder 11 fixed to the upper end of the support column 4, the output end of the first cylinder 11 passing through the support column 4 and fixed to the upper end of the first slide plate 9, a second cylinder 12 fixed to the upper end of the first slide plate 9, the output end of the second cylinder 12 passing through the first slide plate 9 and fixed to the upper end of the second slide plate 10, and a translation assembly disposed at the upper end of the second slide plate 10.

[0029] When it is necessary to move the end of the grease injection head 5 into one of the grooves, the first cylinder 11 is activated, which moves the first slide plate 9 downward. The downward movement of the first slide plate 9 moves the second cylinder 12 downward, which moves the second slide plate 10 downward. The downward movement of the second slide plate 10 moves the translation component downward, thereby moving the end of the grease injection head 5 into one of the grooves. When it is necessary to move the end of the grease injection head 5 into another groove, the second cylinder 12 is activated, which moves the second slide plate 10 downward, and at the same time moves the translation component downward, thereby moving the end of the grease injection head 5 into another groove.

[0030] The translation assembly includes a slide rail fixed to the upper end of the second slide plate 10, a slider 13 slidably connected to the slide rail, a grease injection head 5 fixed to the side wall of the slider 13, a third cylinder 14 fixed to the side wall of the support column 4, and the output end of the third cylinder 14 fixed to the side wall of the slider 13.

[0031] When it is necessary to move the grease injection head 5 horizontally, the third cylinder 14 is activated to move the slider 13, thereby moving the grease injection head 5 horizontally.

[0032] The grease compression assembly includes two fourth cylinders 15 disposed on both sides of the grease tank 2. The same support plate 16 is fixed on the output end of the two fourth cylinders 15. Two connecting rods 17 are symmetrically fixed on the lower end of the support plate 16. The grease compression plate 3 is simultaneously fixed to the lower end of the two connecting rods 17.

[0033] When it is necessary to move the pressure plate 3 downward, the two fourth cylinders 15 are activated simultaneously to move the support plate 16 downward. The downward movement of the support plate 16 causes the two connecting rods 17 to move downward, thereby moving the pressure plate 3 downward.

[0034] The rotatable three-jaw chuck 8 includes a motor 18 fixed inside the body 1. A disc 19 is fixed on the output end of the motor 18 through the body 1, and the three-jaw chuck 8 is fixed on the upper end of the disc 19.

[0035] When it is necessary to rotate the three-jaw chuck 8, start the motor 18 to drive the disc 19 to rotate, which in turn drives the three-jaw chuck 8 to rotate.

[0036] Working principle:

[0037] When grease needs to be injected into the two grooves of the wheel hub bearing, the wheel hub bearing is placed on the upper end of the three-jaw chuck 8 and clamped and fixed by the three-jaw chuck 8. The third cylinder 14 is activated, which moves the slider 13, thereby moving the grease injection head 5 horizontally. At the same time, the first cylinder 11 is activated, which moves the first slide plate 9 downward. The downward movement of the first slide plate 9 moves the second cylinder 12 downward, which moves the second slide plate 10 downward. The downward movement of the second slide plate 10 moves the translation assembly downward, thereby moving the end of the grease injection head 5 into one of the grooves. Then, the two fourth cylinders 15 are activated simultaneously, which moves the support plate 16 downward. The downward movement of the support plate 16 moves the two connecting rods 17 downward, thereby driving the grease injection. Plate 3 moves downward, which can squeeze out the grease in grease tank 2 and force the grease through grease delivery pipe 7 and pressure reducing valve 6, and squeeze it out from the end of grease injection head 5. At the same time, motor 18 is started, driving disc 19 to rotate. The rotation of disc 19 drives three-jaw chuck 8 to rotate, which in turn drives wheel hub bearing to rotate, so that grease can be evenly injected into one groove of wheel hub bearing. After grease injection is completed, the second cylinder 12 is started, driving the second slide plate 10 to move downward, and at the same time driving the translation component to move downward, so that the end of grease injection head 5 can be moved to another groove. The above operation is repeated, so that grease can be evenly injected into both grooves of wheel hub bearing. Under the action of pressure reducing valve 6, the amount of grease in grease delivery pipe 7 can be precisely adjusted, so as to effectively control the amount of grease injected.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
