Description

Technical Field

[0001] This utility model relates to the field of motor lubrication technology, and in particular to a motor lubrication device. Background Technology

[0002] In industrial production, especially in the manufacturing of micro motors or precision motors, precise lubrication of internal moving parts is a crucial step in ensuring performance and extending service life. While existing motor lubrication devices can achieve basic lubrication functions, they still face some challenges in practical applications. One challenge lies in fixing different motor models. Due to the significant differences in motor size and shape, traditional fixing methods often require complex adjustments or replacement of special tooling for each model. This not only consumes a lot of time and manpower but also significantly reduces production efficiency. Existing technologies lack sufficient flexibility and versatility in fixing motors, making it difficult to quickly adapt to different specifications of motors. This leads to cumbersome line change operations, thereby limiting the capacity of automated production lines.

[0003] Besides the shortcomings in motor mounting, existing motor lubrication devices also have deficiencies in oil filtration. The cleanliness of the lubricating oil directly affects the motor's performance and reliability. However, in actual operating environments, the oil is inevitably contaminated by dust, particles, and other impurities. The existing device's filtration mechanism often suffers from poor sealing in its structural design. When the oil flows through the filtration mechanism, unfiltered oil bypasses the filter screen directly through the gap between the filter screen and the mounting groove, causing oil bypass. This prevents the effective removal of impurities from the oil. This bypass not only reduces the filtration effect but also introduces additional impurities into the motor, damaging its precision components and affecting its long-term operational stability. Furthermore, the poor sealing of the filtration mechanism can lead to oil leakage at the joints, causing environmental pollution and oil waste. In addition, the installation and removal of existing filters are usually cumbersome, making timely cleaning or replacement difficult. These factors combined result in the shortcomings of existing technology in ensuring the quality of the lubricating oil and the ease of maintenance.

[0004] Therefore, this utility model proposes a motor oiling device to overcome the shortcomings of the prior art. Summary of the Invention

[0005] In view of the problems existing in the motor lubrication device, such as inconvenience in fixing different types of motors, low operating efficiency, poor sealing of the oil filtration mechanism, bypass leakage, and inconvenience in disassembly and maintenance, this utility model aims to provide a motor lubrication device with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a motor oiling device, including: a worktable, an oiling device; a fixing mechanism, the fixing mechanism including two cylinders, a connecting block, a clamping block, a crank, a U-shaped block and a disc spring; and a filtering mechanism, the filtering mechanism including a filter screen, a mounting groove, a pin, a mounting groove, a disc spring, and a sealing ring.

[0007] The fixing mechanism includes two cylinders, which are symmetrically fixedly connected to the top of the worktable. Each cylinder's output end is fixedly connected to a connecting block, and the outer wall of the connecting block has a positioning groove along its length. A clamping block is slidably fitted within the positioning groove, and its outer wall has a fixing groove along its length. A crank is rotatably connected to the top of the connecting block, with one end extending into the connecting block and rotatably connected to a U-shaped block. A disc spring is installed inside the outer wall of the connecting block, and a U-shaped block is installed at the end of the disc spring. The U-shaped block, through the rotation of the crank, presses the disc spring along the radial direction of the connecting block and engages or disengages from the fixing groove of the clamping block. The rebound force of the disc spring causes the U-shaped block to adhere to the inner side of the crank to prevent the crank from loosening. When the cylinders are activated, they push the connecting block to move laterally along the worktable, causing the connecting block to move and clamp the motor.

[0008] Furthermore, the outer wall of the oiling device is provided with an installation groove 1, and a filter screen is slidably installed inside the installation groove 1; both the outer wall of the filter screen and the side wall of the installation groove 1 are provided with circular grooves for mutual alignment, and the outside of the circular grooves are connected by pins to fix the filter screen inside the oiling device; the upper and lower ends of the inner wall of the installation groove 1 are provided with installation grooves 2, and multiple disc springs 2 are equidistantly installed along the circumferential direction on the inner wall of the installation groove 2. Each disc spring 2 has a sealing ring installed at its end. The sealing ring is squeezed by the outer wall of the filter screen, which squeezes the disc spring 2. The rebound force of the disc spring 2 makes the sealing ring tightly fit the outer wall of the filter screen.

[0009] Preferably, the clamping block can be replaced according to the model of the motor to be energized, and the inner shape of the clamping block is adapted to the outer shape of the motor.

[0010] Preferably, the circular groove is a through hole that penetrates the mounting groove and the thickness direction of the filter screen, and the pin is a detachable cylindrical pin.

[0011] Preferably, the disc spring is arranged in a compressed state between the inner wall of the connecting block and the U-shaped block, and the elastic force drives the U-shaped block to reset when it is not driven by the crank.

[0012] Preferably, the connecting block and clamping block slide along the linear guide rail on the worktable to achieve precise positioning of the motor.

[0013] Preferably, the number of disc springs is at least two, and the sealing ring is an elastic O-ring or a rectangular ring.

[0014] Preferably, after the filter screen is installed in place, the sealing ring fits tightly against the outer wall of the filter screen to prevent oil from bypassing through the gap between the filter screen and the mounting groove.

[0015] Preferably, the top of the mounting slot is provided with an opening for inserting and removing the filter screen.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting a quick-change clamping block structure, combined with cylinder drive and crank locking mechanism, solves the problems of inconvenience and low efficiency in fixing different types of motors in the prior art, and achieves the effect of universal compatibility fixing of multiple motors, simple operation, and stable and efficient oiling process.

[0017] 2.

It achieves the effect of ensuring the cleanliness of the oil dispensing process, preventing impurity contamination, and facilitating the disassembly and cleaning of the filter screen.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model. Example

[0021] Please refer to Figures 1 to 6 This utility model provides a motor oiling device, which aims to solve the problems of inconvenience and low efficiency in fixing different types of motors in the prior art, as well as the insufficient sealing of the oil filtration mechanism 4, which easily leads to oil bypass, impurity infiltration or leakage.

[0022] Please refer to Figure 1 and Figure 2 A motor lubrication device includes a workbench 1, a filter mechanism 4, and a lubrication device 2 fixedly connected to the workbench 1. The workbench 1 serves as the mounting base for the entire device and the bearing platform for the motor, while the lubrication device 2 is used to perform lubrication operations on the motor.

[0023] Please refer to Figure 1 , Figure 2 and Figure 3 The fixing mechanism 3 includes two cylinders 301, which are symmetrically fixedly connected to the top of the workbench 1. Each cylinder 301 has a connecting block 302 fixedly connected to its output end. The outer wall of the connecting block 302 is provided with a positioning groove 304 along the length direction. A clamping block 303 is slidably fitted in the positioning groove 304. The outer wall of the clamping block 303 is provided with a fixing groove 308 along the length direction.

[0024] A crank 305 is rotatably connected to the top of the connecting block 302. One end of the crank 305 extends into the interior of the connecting block 302 and is rotatably connected to the U-shaped block 306. A disc spring 307 is installed inside the outer wall of the connecting block 302. A U-shaped block 306 is installed at the end of the disc spring 307. The U-shaped block 306 presses the disc spring 307 along the radial direction of the connecting block 302 by the rotation of the crank 305, and can be inserted into or released from the fixing groove 308 of the clamping block 303. The rebound force of the disc spring 307 makes the U-shaped block 306 fit against the inner side of the crank 305 to prevent the crank 305 from loosening.

[0025] When cylinder 301 starts, it pushes connecting block 302 to move in the lateral direction of worktable 1. Connecting block 302 drives clamping block 303 to move, so as to clamp and fix the motor. Clamping block 303 can be replaced according to the model of the motor to be lubricated. The inner shape of clamping block 303 is adapted to the outer shape of the motor. This clamping and fixing structure ensures high stability and accurate positioning of different models of motors during the lubrication process.

[0026] Please refer to Figure 4 , Figure 5 and Figure 6 The outer wall of the oiling device 2 is provided with an installation groove 402, and a filter screen 401 is slidably installed inside the installation groove 402.

[0027] Both the outer wall of the filter screen 401 and the side wall of the mounting groove 402 are provided with circular grooves 404 for mutual alignment. The outside of the circular grooves 404 is connected by a pin 403 to fix the filter screen 401 in the oiling device 2. The circular groove 404 is a through hole that passes through the mounting groove 402 and the filter screen 401 in the thickness direction. The pin 403 is a detachable cylindrical pin. This structure facilitates the quick installation, removal and cleaning of the filter screen 401.

[0028] The inner wall of the mounting groove 402 is provided with mounting groove 405 at both the upper and lower ends. Multiple disc springs 406 are installed at equal intervals along the circumferential direction on the inner wall of the mounting groove 405. There are at least two disc springs 406. A sealing ring 407 is installed at the end of each disc spring 406. The sealing ring 407 is an elastic O-ring or a rectangular ring.

[0029] The sealing ring 407 is squeezed by the outer wall of the filter screen 401, which in turn squeezes the disc spring 406. The rebound force of the disc spring 406 makes the sealing ring 407 fit tightly against the outer wall of the filter screen 401. This tight fit can effectively prevent oil from bypassing through the gap between the filter screen 401 and the mounting groove 402, while preventing impurities from seeping in and oil from leaking, thus ensuring the reliability of the filtration effect.

[0030] The top of the mounting slot 402 is provided with an opening for inserting and removing the filter 401, which further improves the ease of maintenance of the filter 401.

[0031] Disc spring 307 is arranged in a compressed state between the inner wall of connecting block 302 and U-shaped block 306. The elastic force drives U-shaped block 306 to reset when it is not driven by crank 305. Connecting block 302 and clamping block 303 slide along linear guide rail on worktable 1 to achieve precise positioning of motor.

[0032] Working principle: When lubricating the motor, first place the motor on the workbench 1, then place the clamping block 303 corresponding to the motor model on the workbench 1. Since the workbench 1 is equipped with a connecting block 302, and the outer wall of the connecting block 302 has a positioning groove 304, the clamping block 303 is first slid into the positioning groove 304 of the connecting block 302 to complete the positioning. Since the top of the connecting block 302 is rotatably connected to the crank 305, and a disc spring 307 is installed inside the outer wall of the connecting block 302, with a U-shaped block 306 installed at the end of the disc spring 307, and a fixing groove 308 is opened on the outer wall of the clamping block 303, when the clamping block 303 is fully inserted into the positioning groove 304, the clamping block is fixed. The slot 308 and the U-shaped block 306 will align with each other. Then, the crank 305 is rotated. The structure of the crank 305 drives the U-shaped block 306 to squeeze the disc spring 307, so that the U-shaped block 306 is stuck into the fixed slot 308. At this time, the disc spring 307 rebounds, so that the U-shaped block 306 fits against the crank 305 to prevent the crank 305 from loosening. Then, the two cylinders 301 fixedly connected to the worktable 1 are started. Since the connecting block 302 is fixedly connected to the output end of the cylinder 301, the cylinder 301 will push the connecting block 302 to move. The connecting block 302 drives the clamping block 303 to move, thereby fixing the motor. The fixing mechanism 3 installed on the worktable 1 can fix motors of different models. When oil filtration is required, the outer wall of the oil dispensing device 2 has a mounting groove 402, and a filter screen 401 is installed on the outside of the mounting groove 402. Therefore, the filter screen 401 is first placed into the mounting groove 402. Since both the filter screen 401 and the outer wall of the oil dispensing device 2 have circular grooves 404, and pins 403 are installed on the outside of the circular grooves 404, when the filter screen 401 is fully inserted into the mounting groove 402, the two circular grooves 404 will align with each other. Then, the pins 403 are inserted into the circular grooves 404, thereby fixing the filter screen 401 inside the oil dispensing device 2. Simultaneously, mounting grooves 405 are provided at both the upper and lower ends of the inner wall of the mounting groove 402. Multiple disc springs 406 are equidistantly installed on the inner wall of the second mounting groove 405, and sealing rings 407 are installed at the ends of the disc springs 406. Therefore, when the filter screen 401 is fully inserted into the first mounting groove 402, the outer wall of the filter screen 401 will squeeze the sealing rings 407 and the disc springs 406. At this time, the rebound of the disc springs 406 will make the sealing rings 407 tightly fit the outer wall of the filter screen 401, which can prevent oil bypass, impurities from seeping in and oil from leaking. It also prevents unfiltered oil from bypassing the filter screen 401 and flowing directly through the gap between the filter screen 401 and the first mounting groove 402. At the same time, it is convenient to disassemble and clean the filter screen 401. Finally, the oiling device 2 is started to oil the motor.
