Abstract
Description
Technical Field
[0001] This utility model relates to the field of coupling technology, and in particular to a coupling grease injection and sealing device. Background Technology
[0002] As a key component in mechanical transmission systems, couplings are widely used in equipment such as motors, pumps, fans, and speed reducers. Their main function is to connect two shafts and allow a certain amount of displacement and deflection while transmitting torque to compensate for installation errors or absorb vibration. In order to ensure the long-term stable operation of couplings, it is usually necessary to inject grease into the bearings or splines inside to reduce wear, prevent corrosion, and extend service life.
[0003] In existing technologies, the grease injection process for couplings is mostly done manually. Operators use a manual grease gun to apply grease to the injection port, and then seal it with a rubber plug or screw plug. However, this traditional method has the following significant drawbacks: the manual grease gun relies on the operator's experience to control the amount of grease injected, which is difficult to quantify precisely, and is prone to over-injection or under-injection; the sealing process involves manually tightening the rubber plug or screw plug, making it difficult to accurately control the sealing pressure and position, which can easily lead to incomplete sealing or damage to the sealing components; and manual grease injection requires aligning each injection port with the grease gun and repeatedly adjusting the angle, resulting in a long operation time per unit, thus requiring improvement. Utility Model Content
[0004] The purpose of this invention is to solve the problems of poor grease injection accuracy and uniformity, poor sealing reliability, low operating efficiency and high labor intensity in the existing technology, and to propose a coupling grease injection and sealing device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A coupling grease injection and sealing device includes a frame, with vertical plates symmetrically arranged on the upper surface of the frame, clamping plates on the inner side of the vertical plates, a moving block fixedly connected to the lower surface of the vertical plates, a bidirectional lead screw rotatably connected inside the vertical plates, a motor fixedly installed on the side of the vertical plates, a sliding rod fixedly installed on the inner side of the vertical plates, a horizontal plate fixedly installed on the side of the frame, an L-plate on the upper surface of the horizontal plate, a grease reservoir fixedly installed on the upper surface of the L-plate, a metering pump fixedly connected to the outlet of the grease reservoir, a hydraulic cylinder fixedly installed on the upper surface of the L-plate, a grease injection head fixedly connected to the output end of the hydraulic cylinder, a conveying telescopic pipe fixedly connected to the output end of the metering pump, a hydraulic cylinder two fixedly installed on the side of the L-plate, a mounting plate fixedly connected to the output end of the hydraulic cylinder two, a pressing head fixedly installed on the side of the mounting plate, a guide rod fixedly installed on the side of the mounting plate, and an adjustment mechanism fixedly installed on the inner side of the horizontal plate. The adjustment mechanism includes a hydraulic cylinder three, which is fixedly installed on the side of the horizontal plate. A connecting block is slidably connected inside the horizontal plate, and a guide rod two is fixedly installed inside the horizontal plate.
[0006] Preferably, the output end of the motor is fixedly connected to one end of the bidirectional lead screw, the moving block is threadedly connected to the bidirectional lead screw, and the moving block is slidably connected to the slide rod.
[0007] Preferably, the end of the conveying telescopic tube away from the metering pump is fixedly connected to the feed end of the grease injection head, and the grease injection head is located directly above the clamping plate.
[0008] Preferably, the guide rod one is slidably connected to the L plate, and the guide rod one is provided in two sets and symmetrically distributed on both sides of the hydraulic cylinder two.
[0009] Preferably, the output end of the hydraulic cylinder three is fixedly connected to the side of the connecting block, and the connecting block is slidably connected to the guide rod two.
[0010] Preferably, a rotating mechanism is fixedly installed on the side of the upright plate. The rotating mechanism includes a rotating box, a worm gear is rotatably connected inside the rotating box, a motor is fixedly installed on the surface of the rotating box, a bearing is fixedly installed on the inner side of the rotating box, a rotating shaft is rotatably connected inside the rotating box, and a worm wheel is fixedly installed at one end of the rotating shaft.
[0011] Preferably, one end of the rotating shaft is fixedly connected to the side of the clamping plate, the output end of the second motor is fixedly connected to one end of the worm gear, the worm wheel and the worm gear mesh with each other, and one end of the rotating shaft is fixedly connected to the inner ring of the bearing.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. This utility model uses symmetrically arranged vertical plates on the upper surface of the frame, connected to a moving block via a bidirectional screw. When the motor drives the bidirectional screw to rotate, it causes the clamping plates on both sides to move closer or further away along the sliding rod, which can quickly adapt to couplings of different sizes and achieve stable clamping. A metering pump is connected to the grease injection head through a conveying telescopic pipe. A hydraulic cylinder drives the grease injection head to move vertically downward to the grease injection port of the coupling directly above the clamping plate. With the precise flow control of the metering pump, grease can be injected accurately according to the preset value, avoiding the situation of over-injection or under-injection caused by experience differences in traditional manual grease injection. The design of the adjustment mechanism allows for adjustment of the lateral position of the grease injection head and the pressing head, thereby adapting to different positional requirements of the grease injection and pressing processes and improving the versatility of the equipment.
[0013] 2. This utility model uses a rotating mechanism on the side of the upright plate to drive the worm gear to rotate via a motor, which in turn drives the worm wheel and the rotating shaft to rotate. The rotating shaft drives the clamping plate and the coupling to rotate synchronously, so that the grease injection head and the pressing head can be aligned with the grease injection hole at any position in the circumference of the coupling without moving. This achieves precise matching of grease injection and sealing at multiple angles and effectively solves the positioning deviation problem caused by frequent movement of the grease injection head or the pressing head.

[0016] 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.
[0017] 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.
[0018] Example 1: As Figures 1-4As shown, this utility model provides a coupling grease injection and sealing device, including a frame 1. Vertical plates 2 are symmetrically arranged on the upper surface of the frame 1. Clamping plates 3 are arranged on the inner side of the vertical plates 2. A moving block 4 is fixedly connected to the lower surface of the vertical plates 2. A bidirectional lead screw 5 is rotatably connected inside the vertical plates 2. A motor 6 is fixedly installed on the side of the vertical plates 2. A sliding rod 7 is fixedly installed on the inner side of the vertical plates 2. A horizontal plate 8 is fixedly installed on the side of the frame 1. An L-plate 9 is provided on the upper surface of the horizontal plate 8. A grease reservoir 10 is fixedly installed on the upper surface of the L-plate 9. A metering pump 11 is fixedly connected to the outlet of the grease reservoir 10. A hydraulic cylinder 12 is fixedly installed on the upper surface of the L-plate 9. A grease injection head 13 is fixedly connected to the output end of the hydraulic cylinder 12. A conveying telescopic pipe 14 is fixedly connected to the output end of the metering pump 11. A second hydraulic cylinder 15 is fixedly installed on the side of the L-plate 9. A mounting plate 16 is fixedly connected to the output end of the second hydraulic cylinder 15. A pressure... The mounting head 17 and mounting plate 16 are fixedly mounted with guide rod 18 on the side. The inner side of the horizontal plate 8 is fixedly mounted with adjustment mechanism 19, which includes hydraulic cylinder 191. Hydraulic cylinder 191 is fixedly mounted on the side of the horizontal plate 8. Connecting block 192 is slidably connected inside the horizontal plate 8. Guide rod 193 is fixedly mounted inside the horizontal plate 8. The output end of motor 6 is fixedly connected to one end of double-acting screw 5. Moving block 4 is threadedly connected to double-acting screw 5. Moving block 4 is slidably connected to slide rod 7. The end of conveying telescopic tube 14 away from metering pump 11 is fixedly connected to the feed end of grease injection head 13. Grease injection head 13 is located directly above clamping plate 3. Guide rod 18 is slidably connected to L plate 9. There are two sets of guide rod 18 symmetrically distributed on both sides of hydraulic cylinder 15. The output end of hydraulic cylinder 191 is fixedly connected to the side of connecting block 192. Connecting block 192 is slidably connected to guide rod 193.
[0019] In this embodiment, the coupling to be processed is placed between two clamping plates 3. Then, the motor 6 is started by an external controller. The motor 6 drives the bidirectional lead screw 5 to rotate. Since the moving block 4 is threadedly connected to the bidirectional lead screw 5 and slides with the slide rod 7, the two upright plates 2 move synchronously towards each other, so that the clamping plates 3 automatically center and firmly clamp the coupling. Subsequently, the hydraulic cylinder 12 drives the grease injection head 13 to descend vertically, so that it is accurately inserted into the grease injection hole at the top of the coupling. The metering pump 11 injects grease into the internal cavity through the delivery telescopic tube 14 according to preset parameters. After the grease injection is completed, the grease injection head 13 automatically retracts. Then, the control... Hydraulic cylinder 15 pushes the mounting plate 16 to move, and the pressing head 17 presses the sealing plug into the grease injection hole to complete the sealing. This effectively avoids lubrication failure or leakage caused by uneven grease injection and poor sealing in traditional manual operation, significantly improving work efficiency and product quality consistency. In addition, the adjustment mechanism 19 pushes the connecting block 192 to slide along the guide rod 193 through hydraulic cylinder 191, which drives the L plate 9, grease injection head 13, and pressing head 17 to move laterally. This allows for flexible adaptation to the positional differences of the grease injection hole and sealing port of different couplings, eliminating the need for overall equipment movement and greatly improving the equipment's compatibility with multiple specifications and positional requirements.
[0020] Example 2: As Figures 1-4 As shown, a rotating mechanism 20 is fixedly installed on the side of the upright plate 2. The rotating mechanism 20 includes a rotating box 201, a worm gear 202 is rotatably connected inside the rotating box 201, a motor 203 is fixedly installed on the surface of the rotating box 201, a bearing 204 is fixedly installed on the inner side of the rotating box 201, a rotating shaft 205 is rotatably connected inside the rotating box 201, a worm wheel 206 is fixedly installed at one end of the rotating shaft 205, one end of the rotating shaft 205 is fixedly connected to the side of the clamping plate 3, the output end of the motor 203 is fixedly connected to one end of the worm gear 202, the worm wheel 206 and the worm gear 202 mesh with each other, and one end of the rotating shaft 205 is fixedly connected to the inner ring of the bearing 204.
[0021] In this embodiment, by starting motor 203, motor 203 drives worm 202 to rotate. Worm 202 meshes with worm wheel 206 to drive shaft 205 to rotate around vertical axis. Since shaft 205 is fixedly connected to clamping plate 3, coupling rotates synchronously to the required angle, so that the target grease injection hole is aligned with grease injection head 13 directly above. The rotating mechanism 20 adopts worm wheel 206 and worm 202 structure, which has self-locking characteristics and can be stably stopped at any angle, ensuring that the position of coupling does not shift during grease injection and pressing. With this design, the equipment can adapt to grease injection needs at any circumferential position without additional movement of grease injection head 13 or pressing head 17.
[0022] The working principle of this embodiment is as follows: In use, the coupling to be processed is first placed between two clamping plates 3. The motor 6 is started by an external controller, driving the bidirectional lead screw 5 to rotate. Since the moving block 4 is threadedly connected to the bidirectional lead screw 5 and slides with the slide rod 7, the two vertical plates 2 move synchronously towards each other, allowing the clamping plates 3 to automatically center and securely clamp the coupling. Next, the hydraulic cylinder 12 drives the grease injection head 13 to descend vertically, precisely inserting it into the grease injection hole at the top of the coupling. The metering pump 11 injects grease into the internal cavity of the coupling according to preset parameters through the delivery telescopic tube 14. After grease injection, the grease injection head 13 automatically retracts. Then, the motor 203 drives the worm gear 202 to rotate. The worm gear 202 meshes with the worm wheel 206, driving the rotating shaft 205 to rotate around the vertical axis. The clamping plate 3 is fixedly connected, and the coupling rotates synchronously to the required angle so that the target grease injection hole is aligned with the press-fit head 17. Then, the hydraulic cylinder 2 15 is controlled to push the mounting plate 16 downward, and the press-fit head 17 presses the sealing plug into the grease injection hole to complete the sealing. During this process, the hydraulic cylinder 3 191 in the adjusting mechanism 19 can push the connecting block 192 to slide along the guide rod 2 193, which drives the L plate 9, grease injection head 13, and press-fit head 17 to move laterally. This flexibly adapts to the position differences of the grease injection hole and sealing port of different couplings. There is no need to move the entire equipment. In the entire operation process, all actions are coordinated and controlled by an external controller to ensure that all components operate in an orderly manner, which significantly improves the work efficiency and product quality consistency. Moreover, the equipment can flexibly adapt to the needs of multiple specifications and multiple positions without manual intervention, reducing operational errors caused by differences in experience.
