Description

Technical Field

[0001] This utility model relates to the field of automatic grease application machine technology, and in particular to an automatic grease application machine for bearing assembly. Background Technology

[0002] A grease applicator is a device used to apply grease and lubricating oil to mechanical parts. Its main function is to ensure the lubrication of mechanical parts during operation, so as to reduce friction and wear, extend the service life of the equipment, and improve work efficiency.

[0003] In the existing technology, when assembling bearings, grease needs to be applied to the bearings to ensure that the bearings are properly lubricated. When workers manually apply grease to the bearings, it is difficult to accurately control the amount applied to the bearings because it is a manual operation. This can lead to uneven application of grease and thus fail to guarantee the quality of grease application. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where it is difficult to accurately control the amount of grease applied to the bearing by manual operation, which leads to uneven application of grease and thus cannot guarantee the quality of grease application. Therefore, an automatic grease application machine for bearing assembly is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic grease applicator for bearing assembly, comprising a worktable, a movable component at the bottom of the worktable, the movable component including a motor, an output shaft fixedly connected to the output end of the motor, a first gear fixedly sleeved on the outer surface of the output shaft, a first fixed shaft fixedly embedded near the center of the bottom of the worktable, a second gear rotatably connected to the outer surface of the first fixed shaft, a second fixed shaft fixedly connected to the outer surface of the second gear, a movable rod movably sleeved on the outer surface of the second fixed shaft, and a third fixed shaft movably embedded near one end of the outer surface of the movable rod.

[0006] Preferably, the outer surface of the first gear meshes with the outer surface of the second gear, and one end of the third fixed shaft is fixedly connected to the fourth fixed shaft.

[0007] Preferably, a fixing plate is fixedly connected to the bottom of the workbench near one side edge, the motor is disposed on the outer surface of the fixing plate, and a sliding groove is provided on the top of the workbench.

[0008] Preferably, the inner wall of the chute is slidably connected to the outer surface of the fourth fixed shaft, and a support block is fixedly connected to the top of the worktable near the center.

[0009] Preferably, a grease-applying pipe is fixedly connected to the outer surface of the support block, and a movable shaft is fixedly sleeved on the outer surface of the fourth fixed shaft near the top, with one end of the movable shaft fixedly connected to the movable block.

[0010] Preferably, the outer surface of the movable block is in contact with the inner wall of the grease application pipe, and a first rotating shaft is fixedly connected to the top of the workbench, and a plurality of uniformly arranged first anti-slip pads are fixedly connected to the top of the first rotating shaft.

[0011] Preferably, the inner wall of the first rotating shaft is threadedly connected to a second rotating shaft, and the outer surface of the second rotating shaft is fixedly connected with a plurality of uniformly arranged second anti-slip pads.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the device is equipped with a moving component. When the motor drives the bearing to rotate, the motor will also drive the moving component to rotate. The first gear drives the second gear to rotate, and the second gear drives the moving rod to move. The moving rod drives the moving shaft to move along the grease pipe, squeezing out the grease in the grease pipe. Since the speed of the motor driving the first gear is uniform, the moving block moves at a uniform speed in the grease pipe, squeezing the grease evenly from the grease pipe, thus ensuring the grease coating quality.

[0014] 2. In this utility model, by setting a first anti-slip pad and a second anti-slip pad, the operator places the center of the bearing at the center of the first rotating shaft, and then connects the second rotating shaft to the first rotating shaft by thread. At this time, the first anti-slip pad and the second anti-slip pad are located on the upper and lower surfaces of the bearing and fit against the bearing. Thus, when the motor drives the bearing to rotate, the stability of the bearing can be guaranteed, thereby ensuring the stability of the automatic grease applicator for bearing assembly.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1: As Figures 1-9As shown, this utility model provides an automatic grease applicator for bearing assembly, including a worktable 1. A movable assembly 2 is provided at the bottom of the worktable 1. The movable assembly 2 includes a motor 201. The output end of the motor 201 is fixedly connected to an output shaft 202. A first gear 203 is fixedly sleeved on the outer surface of the output shaft 202. A first fixed shaft 204 is fixedly embedded near the center of the bottom of the worktable 1. A second gear 205 is rotatably connected to the outer surface of the first fixed shaft 204. A second fixed shaft 206 is fixedly connected to the outer surface of the second gear 205. A movable rod 207 is movably sleeved on the outer surface of the second fixed shaft 206. A movable rod 207 is movably embedded near one end of the outer surface of the movable rod 207. The third fixed shaft 208 has its outer surface meshing with the outer surface of the first gear 203 and the second gear 205. One end of the third fixed shaft 208 is fixedly connected to the fourth fixed shaft 209. A fixed plate 3 is fixedly connected to the bottom of the worktable 1 near one side edge. The motor 201 is mounted on the outer surface of the fixed plate 3. A slide groove 4 is provided on the top of the worktable 1. The inner wall of the slide groove 4 is slidably connected to the outer surface of the fourth fixed shaft 209. A support block 5 is fixedly connected to the top of the worktable 1 near the center. A grease-applying pipe 6 is fixedly connected to the outer surface of the support block 5. A movable shaft 7 is fixedly fitted on the outer surface of the fourth fixed shaft 209 near the top. One end of the movable shaft 7 is fixedly connected to a movable block 8.

[0028] The overall effect of Embodiment 1 is as follows: When using an automatic grease applicator for bearing assembly, the operator first places the bearing on top of the first rotating shaft 9, with the center of the bearing positioned at the center of the first rotating shaft 9. Then, the second rotating shaft 11 is screwed onto the first rotating shaft 9. The bearing is clamped and fixed by the first rotating shaft 9 and the second rotating shaft 11. Then, the motor 201 is started, which drives the output shaft 202 to rotate. When the output shaft 202 rotates, it drives the first rotating shaft 9 to rotate. When the first rotating shaft 9 rotates, it drives the second rotating shaft 11 to rotate. When the first rotating shaft 9 and the second rotating shaft 11 rotate simultaneously, they drive the bearing to rotate. At the same time, the output shaft 202 drives... The first gear 203 rotates, and its outer surface meshes with the outer surface of the second gear 205. Therefore, the first gear 203 drives the second gear 205 to rotate. When the second gear 205 rotates, its center rotates along the outer surface of the first fixed shaft 204. Simultaneously, the second gear 205 drives the second fixed shaft 206 to rotate along its rotation path. As the second fixed shaft 206 rotates, it drives the moving rod 207 to move. One end of the moving rod 207 rotates around the outer surface of the second fixed shaft 206, while the inner wall of the other end of the moving rod 207 drives the third fixed shaft 208 to move. The outer surface of the fixed shaft 208 rotates. When the third fixed shaft 208 moves with the moving rod 207, it drives the fourth fixed shaft 209 to move. The fourth fixed shaft 209 slides linearly along the inside of the slide groove 4. At the same time, the fourth fixed shaft 209 drives the moving shaft 7 to move linearly. The moving shaft 7 drives the outer surface of the moving block 8 to move along the inside of the grease pipe 6, squeezing the grease inside the grease pipe 6. The grease flows out from the other end of the grease pipe 6 to the outer surface of the rotating bearing, and the outer surface of the bearing is evenly coated with grease. This device, by setting the moving component 2, when the motor 201 drives the bearing to rotate, the motor 201 will drive the second gear 20... 5 drives the fourth fixed shaft 209 to move along the slide groove 4, and then drives the moving shaft 7 to move through the fourth fixed shaft 209. The moving shaft 7 will drive the moving block 8 to move along the inside of the grease pipe 6, squeezing the grease in the grease pipe 6 so that it flows out from the outlet of the grease pipe 6 and covers the outer surface of the bearing. Since the motor 201 drives the output shaft 202 to rotate at a constant speed, the moving block 8 also moves at a constant speed along the grease pipe 6. Therefore, the grease also flows out evenly from the outlet of the grease pipe 6 and evenly covers the outer surface of the bearing. This solves the problem that it is difficult to accurately control the amount of grease applied to the bearing by manual operation, which will lead to uneven application of grease on the bearing and thus fail to guarantee the quality of grease application.

[0029] Example 2: Figures 1-9As shown, the outer surface of the movable block 8 is in contact with the inner wall of the grease pipe 6. The top of the workbench 1 is fixedly connected to the first rotating shaft 9. The top of the first rotating shaft 9 is fixedly connected to a plurality of uniformly arranged first anti-slip pads 10. The inner wall of the first rotating shaft 9 is threadedly connected to the second rotating shaft 11. The outer surface of the second rotating shaft 11 is fixedly connected to a plurality of uniformly arranged second anti-slip pads 12.

[0030] The effect achieved by the entire embodiment 2 is as follows: When using an automatic grease applicator for bearing assembly, the operator needs to first fix the bearing. The operator needs to place the bearing on top of the first rotating shaft 9, with the center of the bearing at the center of the first rotating shaft 9. At this time, the first anti-slip pad 10 is in contact with the outer surface of the bearing. Then, the operator moves the second rotating shaft 11 in a spiral motion, aligning it with the inside of the first rotating shaft 9, until the second anti-slip pad 12 is in contact with the other outer surface of the bearing. Then, the operator stops rotating the second rotating shaft 11. Then, the operator starts the motor 201, which drives the first rotating shaft 9 to rotate. When the first rotating shaft 9 rotates, it drives the second rotating shaft 11 to rotate. When the first rotating shaft 9 and the second rotating shaft 11 rotate simultaneously, they drive the bearing to rotate. The first anti-slip pad 10 and the second anti-slip pad 12 can increase the clamping force on the bearing, effectively preventing the bearing from moving during rotation, thereby ensuring the stability of the automatic grease applicator for bearing assembly during use.

[0031] Working Principle: When using an automatic grease applicator for bearing assembly, the operator first places the center of the bearing at the center of the first rotating shaft 9, and then screws the second rotating shaft 11 to the first rotating shaft 9. At this time, the first anti-slip pad 10 and the second anti-slip pad 12 are located on both sides of the bearing, thereby increasing the clamping force of the first rotating shaft 9 and the second rotating shaft 11 on the bearing. Starting the motor 201 will drive the first rotating shaft 9 and the second rotating shaft 11 to rotate. When the first rotating shaft 9 and the second rotating shaft 11 drive the bearing to rotate, the motor 201 will simultaneously drive the first gear 203 to rotate, which in turn drives the second gear 205 to rotate. The second gear 205 will then drive the second fixed shaft 206 to rotate. As the second fixed shaft 206 rotates, it will cause one end of the moving rod 207 to rotate and move around the outer surface of the second fixed shaft 206. The other end of the moving rod 207 drives the third fixed shaft 208 to move, which in turn drives the fourth fixed shaft 209 to move. The fourth fixed shaft 209 slides linearly along the inside of the slide groove 4. At the same time, the fourth fixed shaft 209 drives the moving shaft 7 to move linearly. The moving shaft 7 drives the outer surface of the moving block 8 to move along the inside of the grease pipe 6, squeezing the grease inside the grease pipe 6. The grease flows out from the outlet at the other end of the grease pipe 6 onto the outer surface of the rotating bearing, and the outer surface of the bearing is evenly coated with grease. This device, by setting the moving component 2, and by setting the motor 201 to drive the output shaft 202 to rotate at a constant speed, also causes the moving block 8 to move at a constant speed along the grease pipe 6. Therefore, the grease flows out evenly from the outlet of the grease pipe 6 and evenly covers the outer surface of the bearing, ensuring the quality of grease application.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
