The lubricating grease injection device usually includes components such as a grease box, a delivery pipeline, an oil injection pump and a controller. The operator can set the corresponding parameters on the controller, such as the oil injection amount and the oil injection speed, according to the size and requirements of the bearing. The injection device can automatically control the supply of lubricating grease to improve production efficiency and product quality.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 , the utility model provides an embodiment: a lubricating grease injection device for automobile bearing production, comprising a base 1, a DC motor 5 is fixedly connected to the middle of the top of the base 1, a conical block 6 is fixedly connected to the output end of the DC motor 5, a bidirectional electric telescopic rod 4 is fixedly connected to the front side of the top of the base 1, and a clamping plate 3 is fixedly connected to the telescopic end of the bidirectional electric telescopic rod 4, an electric telescopic rod 7 is fixedly connected to the rear side of the top of the base 1, and a fixed block 8 is fixedly connected to the telescopic end of the electric telescopic rod 7, a moving plate 9 is slidably connected to the top of the fixed block 8, and an injection pipe 10 is fixedly connected to the front side of the top of the moving plate 9, a liquid storage tank 11 is fixedly connected to the right side of the rear of the top of the base 1, and an oil pump 12 is fixedly connected to the left side of the top of the liquid storage tank 11, and the output end of the oil pump 12 is connected to a hose 13, and the hose 13 is connected to the injection pipe 10, and an adjustment mechanism 2 is arranged on the outside of the clamping plate 3, and the adjustment mechanism 2 is used to automatically adapt to the size of the bearing when clamping;

[0025] Specifically, the bearing to be processed is placed on the top of the conical block 6, and is in contact with the inner cylinder of the bearing through the small opening on the top, so that bearings of different sizes can be placed. By starting the electric telescopic rod 7, the fixed block 8 and the injection pipe 10 on the top can be driven to move toward the base 1 together. When it moves to the required position, the oil pump 12 is started to draw the lubricating grease in the liquid storage tank 11 into the hose 13, and the lubricating grease falls on the top of the bearing to be processed through the injection pipe 10. At the same time, the DC motor 5 is started to rotate slowly so that the lubricating grease falls evenly on the bearing. Then, the bidirectional electric telescopic rod 4 is started to make the clamps 3 on both sides move relative to each other to clamp the bearing, and then the output power of the DC motor 5 is increased to speed up the rotation of the conical block 6, thereby driving the internal rotation of the bearing so that the lubricating grease can penetrate evenly into the interior.

[0026] Reference Figure 2 , Figure 3 and Figure 4 The adjusting mechanism 2 includes an inclined groove 201, which is provided at the front and rear sides of the left outer wall of the clamping plate 3, and a moving block 202 is slidably connected to the inner wall of the inclined groove 201, and a spring 203 is fixedly connected to the adjacent side of the two moving blocks 202 on the front and rear sides, and a U-shaped block 204 is fixedly connected to the adjacent side of the two moving blocks 202 on the left and right sides, and a roller 205 is rotatably connected to the inner wall of the U-shaped block 204, and a second rack 209 is fixedly connected to the left side of the top rear portion of the base 1, and a cylinder 207 is rotatably connected to the front side of the fixed block 8, and gears 208 are fixedly connected to the left and right sides of the outer wall of the cylinder 207, and a first rack 206 is provided at the bottom of the movable plate 9, and the gear 208 is meshed and connected with the first rack 206 and the second rack 209 on the adjacent side respectively;

[0027] Specifically, due to the different sizes of the bearings, the positions of the bearings when placed above the conical block 6 will be different. When the splint 3 moves toward the bearing, the roller 205 will preferentially contact its surface. As the movement continues, the U-shaped block 204 will drive the moving block 202 to move forward and rearward respectively, and the spring 203 will stretch at this time. At the same time, during the falling process of the electric telescopic rod 7, the gear 208 is meshed with the second rack 209, which will cause the gear 208 and the cylinder 207 to rotate together, and the rotation of the gear 208 on the right side will drive the first rack 206 to move rearward, so that the position of the injection tube 10 can be automatically adjusted during injection.

[0028] Reference Figure 1 , Figure 2 and Figure 3, an alarm 14 is fixedly connected to the left side of the top of the base 1, and speakers 15 are fixedly connected to the left and right sides of the outer wall of the alarm 14; an observation slot 16 is provided on the right side of the liquid storage tank 11, and an outer frame 17 is fixedly connected to the outer side of the observation slot 16; a conical filling port 18 is fixedly connected to the right side of the top of the liquid storage tank 11, and a box plug 19 is provided on the inner wall of the conical filling port 18; slide grooves 20 are provided on the left and right sides of the top of the base 1, and the slide grooves 20 are slidably connected to the corresponding clamping plates 3 respectively;

[0029] Specifically, the alarm 14 can be used to alert the staff when a fault occurs, the speaker 15 can make a sound to alert the staff, the observation groove 16 can facilitate observation of the remaining situation inside the liquid storage tank 11, the conical filling port 18 can facilitate the addition of lubricating grease to the liquid storage tank 11, and the slide groove 20 can facilitate the movement of the splint 3.

[0030] Reference Figure 1 , Figure 2 and Figure 3 A controller 21 is fixedly connected to the right side of the front top of the base 1, and the controller 21 is electrically connected to the bidirectional electric telescopic rod 4, the DC motor 5, the electric telescopic rod 7 and the oil pump 12 respectively; a housing 22 is fixedly connected to the outside of the controller 21, and a protective cover 23 is rotatably connected to the outside of the housing 22;

[0031] Specifically, the controller 21 can control the starting and operating power between the bidirectional electric telescopic rod 4, the DC motor 5, the electric telescopic rod 7 and the oil pump 12 respectively. The outer shell 22 can prevent the controller 21 from being damaged due to bumps. The protective cover 23 can prevent dust or liquid from entering the interior of the controller 21 and causing damage to the electronic components inside.

[0032] Working principle: before using the device, first, place the bearing to be processed on the top of the conical block 6, and make close contact with the cylinder inside the bearing through the small opening on the top to meet the processing requirements of bearings of different sizes. Then, start the electric telescopic rod 7 to drive the fixed block 8 and the injection pipe 10 above it to move toward the base 1 together. When it moves to the predetermined position, activate the oil pump 12 to suck the lubricating grease in the liquid storage tank 11 into the hose 13, and accurately apply it to the bearing to be processed through the injection pipe 10. At the same time, start the DC motor 5 to drive the bearing to rotate at a slow speed to ensure that the lubricating grease can evenly cover the bearing surface. Then, start the bidirectional electric telescopic rod 4 to prompt the clamps 3 on both sides to move toward each other to effectively clamp the bearing. Then, increase the output power of the DC motor 5 to increase the rotation speed of the conical block 6, thereby driving the internal rotation of the bearing to ensure that the lubricating grease can evenly penetrate into the bearing to achieve a full lubrication effect.

[0033] And through the adjustment mechanism 2, in view of the different sizes of the bearings, the positions of the bearings when placed on the conical block 6 will be different. When the splint 3 approaches the bearing, the roller 205 will first contact its surface. As the splint 3 continues to move, the U-shaped block 204 will drive the moving block 202 to move to the front and rear sides respectively. At this time, the spring 203 will undergo tensile deformation. At the same time, during the descent of the electric telescopic rod 7, through the meshing action of the gear 208 and the second rack 209, the gear 208 and the cylinder 207 will rotate in coordination. In particular, the rotation of the right gear 208 will pull the first rack 206 to move backward, thereby realizing automatic adjustment of the position of the injection tube 10 during the injection process to ensure the accuracy and efficiency of the operation.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
