Technical Field
[0001] This utility model relates to the field of trunnion sleeve processing technology, and in particular to an auxiliary device for trunnion sleeve processing. Background Technology
[0002] A trunnion sleeve is a component fitted over the trunnion, primarily functioning to protect the trunnion from wear and corrosion by external substances, preventing premature aging and thus extending its service life. Simultaneously, the trunnion sleeve also improves the fit accuracy between the trunnion and surrounding components, ensuring the stability and reliability of the mechanical system. Application No. 202120414157.4 discloses an efficient auxiliary device for trunnion sleeve processing, including a worktable and processing equipment for processing the trunnion sleeve. A lifting base is mounted on the worktable surface, the bottom of which is fixedly connected to the output end of a hydraulic device. A cleaning box is fixedly connected to the top of the lifting base, and a cleaning cavity is formed inside the cleaning box… In this patent, the auxiliary cleaning component is raised by using a hydraulic device and a lifting base to clean the sleeve. However, after the lifting base and hydraulic device raise the cleaning component, the cleaning component cannot automatically extend into the sleeve for cleaning, requiring manual operation, increasing the cumbersomeness of cleaning. Therefore, we introduce an auxiliary device for trunnion sleeve processing. Utility Model Content
[0003] The main purpose of this utility model is to provide an auxiliary device for processing trunnion sleeves, which can effectively solve the problems in the background art.

[0023] Please see Figure 1-4 This utility model provides a technical solution:
[0024] An auxiliary device for processing trunnion sleeves includes a base 1, a frame 2 fixedly connected to the upper right side of the base 1, a movable plate 3 disposed inside the frame 2, a cleaning mechanism 4 installed and connected to the right end of the movable plate 3, a bracket 7 fixedly connected to the upper left side of the base 1, a clamping device 6 fixedly connected to the upper end of the bracket 7, and a sleeve body 5 disposed inside the clamping device 6.
[0025] In this embodiment, the cleaning mechanism 4 includes a second motor 41. The output end of the second motor 41 is fixedly connected to a transmission rod 47. The outer surface of the transmission rod 47 is movably connected to a reinforcement member 42 via a bearing. Several support rods 43 are fixedly connected to the left side of the outer surface of the transmission rod 47. The ends of the several support rods 43 away from the transmission rod 47 are connected to a sleeve 44. A sponge 45 is fixedly connected to the right side of the outer surface of the sleeve 44. A cleaning brush 46 is fixedly connected to the left side of the outer surface of the sleeve 44. The second motor 41 is fixedly connected to the right end of the movable plate 3, the reinforcement member 42 is fixedly connected to the left end of the movable plate 3, and the transmission rod 47 passes through the movable plate 3.
[0026] In this embodiment, the clamping device 6 includes an upper clamp 61 and a lower clamp 65. Four bolts 62 are interlocked between the upper clamp 61 and the lower clamp 65, and each bolt 62 is threaded with a nut 63. Anti-slip strips 64 are fixedly connected to the inner walls of both the lower clamp 65 and the upper clamp 61. The lower clamp 65 is fixedly connected to the bracket 7, and both the lower clamp 65 and the upper clamp 61 are located on the outer surface of the bushing body 5. A first motor 22 is fixedly connected to the right end of the frame 2. A threaded rod 23 is fixedly connected to the output end, a positioning rod 21 is fixedly connected to the middle of the inner wall of the frame 2, and a sliding groove 24 is opened on the upper part of the front inner wall and the upper part of the rear inner wall of the frame 2. Folded dustproof plates 25 are fixedly connected to the left and right ends of the movable plate 3, and the two folded dustproof plates 25 are located in the two sliding grooves 24. The positioning rod 21 is inserted into the movable plate 3, the threaded rod 23 is threaded into the movable plate 3, and the ends of the two folded dustproof plates 25 away from the movable plate 3 are fixedly connected to the frame 2.
[0027] It should be noted that this utility model describes an auxiliary device for processing trunnion sleeves. After receiving a start command, the No. 1 motor 22 transmits rotational power stably and efficiently to the connected threaded rod 23, causing it to start rotating synchronously at a uniform speed. The threaded rod 23 is connected to a movable plate 3 by a high-precision thread. As the threaded rod 23 rotates, the movable plate 3, guided precisely by the thread, moves smoothly left and right along the axial direction of the threaded rod 23. A cleaning mechanism 4 is firmly installed on the movable plate 3, and moves synchronously with the left and right movement of the movable plate 3. By precisely controlling the rotation direction and number of revolutions of the No. 1 motor 22, the cleaning mechanism 4 can be fully and accurately inserted into the sleeve body 5, making full preparation for the subsequent comprehensive cleaning of the inner wall of the sleeve body 5. Two parallel and symmetrical sliding grooves 24 are cleverly opened in the frame 2. These two sliding grooves 24 are carefully designed and processed, with smooth surfaces and precise dimensions. A folded dustproof plate 25 is slidably arranged in both sliding grooves 24 and has good flexibility. When the movable plate 3 moves under the drive of the threaded rod 23, the movable plate 3 located between the two folded dustproof plates 25 will interact with the folded dustproof plates 25. As the movable plate 3 moves, the folded dustproof plates 25 will automatically open and close according to the position change of the movable plate 3, like an intelligent protective barrier, always closely fitting the edge of the movable plate 3, thereby effectively preventing dust and other debris generated during cleaning from entering the frame 2, protecting the precision components inside the frame 2 from dust corrosion, and extending the service life of the equipment. When the cleaning mechanism 4 is fully inserted into the bushing body 5, the second motor 41 starts working. The second motor 41 also has efficient and stable performance. Its internal electromagnetic induction device quickly generates strong rotational power, which is transmitted to the transmission rod 47 through the output shaft, causing the transmission rod 47 to start rotating at high speed. As the transmission rod 47 rotates, the sleeve 44 rotates synchronously. A set of high-density cleaning brushes 46 is provided on the left side of the outer surface of the sleeve 44. The cleaning brushes 46 are made of high-quality bristles with good elasticity and wear resistance, and can penetrate into the tiny crevices of the inner wall of the bushing body 5 to thoroughly remove stubborn dirt, rust and other impurities attached to the inner wall. A soft and highly absorbent sponge 45 is provided on the right side of the outer surface of the sleeve 44. During the rotation, the sponge 45 can perform a secondary wiping and cleaning of the inner wall after the cleaning brushes 46 have cleaned it, absorbing the residual dust and moisture, so that the inner wall of the bushing body 5 achieves a clean and new effect. The cleaning brushes 46 and the sponge 45 come into contact with the inner wall of the bushing body 5 in sequence under the action of the sleeve 44. Through this orderly cleaning method, it can be ensured that every part of the inner wall of the bushing body 5 is thoroughly cleaned.
