Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a surface polishing device for motor housings. Background Technology

[0002] The motor housing is the external structural component of the motor, mainly used to enclose, support and protect the core components inside the motor (such as the stator, rotor, windings, etc.), and to provide mechanical support, heat dissipation channels and mounting interfaces for the motor. In order to improve the appearance quality and improve its performance indicators, it needs to be polished.

[0003] During polishing, the corresponding motor housing is placed on a cylindrical mold, and then the cylinder is activated to move the motor housing back and forth to polish it. However, the cylindrical mold has a fixed size. When polishing other models of motor housing, the mold needs to be disassembled. The cylindrical mold is usually fixed to the equipment by bolts, clips, or interference fits. Disassembly requires loosening the bolts one by one, removing the positioning parts, or using special tools. The operation is cumbersome and time-consuming. Therefore, a surface polishing device for motor housing is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a surface polishing device for motor housings, which aims to improve the problem that it is troublesome to change molds when polishing different models of motors in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a surface polishing device for a motor housing, comprising a worktable, a positioning platform fixedly connected to the top rear side of the worktable, an electric telescopic rod fixedly connected to the top front side of the worktable, and an adjustment mechanism detachably installed on the front inner wall of the positioning platform.

A rotating column is rotatably connected to the inner wall of the support plate. A fixed plate is fixedly connected to the outer arc surface of the bottom of the rotating column. A connecting plate is rotatably connected to the side of the fixed plate away from the rotating column. A movable plate is rotatably connected to the side of the connecting plate away from the rotating column. An arc plate is fixedly connected to the side of the movable plate away from the connecting plate. A guide is provided on the upper surface of the base plate. A disassembly assembly is provided at the front of the positioning platform.

[0008] The guide includes a telescopic rod fixedly connected to the upper surface of the base plate, and the movable end of the telescopic rod is fixedly connected to the inner arc surface of the arc plate.

[0009] As a further description of the above technical solution:

[0010] The diameter of the connecting column is smaller than that of the threaded rod, and the outer wall of the connecting column is slidably connected to the inner wall of the rotating column.

[0022] 1. In this utility model, through the cooperation between the workbench, positioning table, electric telescopic rod and its adjustment mechanism, when different motor housings need to be installed, rotating the threaded rod causes the threaded rod to drive the arc plate to move outward, thereby expanding the overall diameter to accommodate different models of motor housings, thus achieving the purpose of quick installation and improving overall work efficiency.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-2 This utility model provides an embodiment of a surface polishing device for motor housings, including a worktable 1. A positioning platform 2 is fixedly connected to the rear top of the worktable 1, and an electric telescopic rod 3 is fixedly connected to the front top of the worktable 1. A polishing disc or sandpaper can be installed on the side of the electric telescopic rod 3 near the positioning platform 2. This is prior art and well known to those skilled in the art, and will not be explained in detail here. An adjustment mechanism 4 is detachably installed on the inner wall of the front part of the positioning platform 2. The adjustment mechanism 4 can be used to install motor housings of different models. A cylinder is provided on the right side of the front part of the positioning platform 2. The cylinder controls the adjustment mechanism 4 to move back and forth to cooperate with the sandpaper for polishing.

[0033] Reference Figures 2-4 The adjustment mechanism 4 includes a base plate 403 detachably mounted on the inner wall of the front part of the positioning platform 2. A support plate 401 is fixedly connected to the top of the base plate 403. The base plate 403 and the support plate 401 are fixedly connected by a cylinder, and the base plate 403 and the support plate 401 are circular to facilitate the fixing of the motor housing. A threaded rod 402 is threadedly connected to the inner wall of the support plate 401, and a connecting column 404 is fixedly connected to the bottom of the threaded rod 402. The two move along the same trajectory. A rotating column 405 is rotatably connected to the inner wall of the support plate 401, and a fixed plate 406 is fixedly connected to the outer arc surface of the bottom of the rotating column 405. The rotation of the rotating column 405 drives the fixed plate 406 to move. A connecting plate 407 is rotatably connected to the side of the fixed plate 406 away from the rotating column 405. A movable plate 408 is rotatably connected to the side of the connecting plate 407 away from the rotating column 405. When the fixed plate 406 rotates, the corresponding connecting plate 407 will also rotate, thereby driving the movable plate 408 to move. An arc plate 409 is fixedly connected to the side of the movable plate 408 away from the connecting plate 407. The movement trajectories of the movable plate 408 and the arc plate 409 are consistent. A guide is provided on the upper surface of the base plate 403. The guide can guide the movement of the arc plate 409. A disassembly assembly 5 is provided at the front of the positioning table 2. The base plate 403 can be quickly disassembled by the disassembly assembly 5.

[0034] Reference Figures 2-4 The guide includes a telescopic rod 410 fixedly connected to the upper surface of the base plate 403. The movable end of the telescopic rod 410 is fixedly connected to the inner arc surface of the arc plate 409. The telescopic rod 410 can move with the arc plate 409 and can only move horizontally. The diameter of the connecting column 404 is smaller than that of the threaded rod 402. This smaller diameter ensures that when the threaded rod 402 moves upward, the connecting column 404 will also move accordingly without motion interference. The outer wall of the connecting column 404 is slidably connected to the inner wall of the rotating column 405. This sliding connection avoids motion interference. The cross-section of the rotating column 405 is cross-shaped. This cross-shaped design prevents the column from falling off during rotation. The bottom horizontal plate of the connecting column 404 is elliptical. This elliptical design ensures that the connecting column 404 moves upward when it rotates, at which time the rotating column 405 rotates synchronously.

[0035] Reference Figures 2-3 and Figure 5The disassembly assembly 5 includes a limiting block 501 fixedly connected to the front of the positioning platform 2. The inner wall of the limiting block 501 is elastically connected to a limiting post 503 via a connecting spring 504. The elasticity of the connecting spring 504 allows the limiting post 503 to have limiting and resetting functions. The outer wall of the limiting post 503 penetrates and slidably connects to the inner wall of the limiting block 501, facilitating manual movement of the limiting post 503. The outer wall of the limiting post 503 also penetrates and slidably connects to the front inner wall of the positioning platform 2, facilitating insertion and fixing. The base plate 4... A round hole is opened at the front of the 03, and the rear of the limiting post 503 is inserted into the inner wall of the round hole. The two are inserted to achieve the purpose of insertion and fixation. A T-shaped plate 502 is fixedly connected to the rear of the base plate 403. The outer wall of the T-shaped plate 502 is inserted into the inner wall of the front of the positioning table 2. The T-shaped plate 502 can play the purpose of pre-positioning, and the setting of the T-shaped plate 502 prevents the base plate 403 from rotating. A slope is opened at the rear of the limiting block 501. The slope is set upward, so that when installing the base plate 403, it can be installed directly downward.

[0036] Working principle: When the motor housing surface polishing equipment is working, the disassembly component 5 is used to quickly install the adjustment mechanism 4. The T-shaped plate 502 at the rear of the base plate 403 is inserted into the inner wall of the front of the positioning table 2. At this time, the inclined surface at the rear of the limiting block 501 is subjected to force, which pushes the limiting post 503 to move away from the positioning table 2 against the elastic force of the connecting spring 504. When the base plate 403 is installed in place and the round hole is aligned with the limiting post 503, the connecting spring 504 resets and pushes the limiting post 503 into the round hole, thus achieving a stable fixation of the base plate 403.

[0037] When installing different types of motor housings, rotating the threaded rod 402, since the threaded rod 402 is threadedly connected to the support plate 401, will cause the connecting column 404 to move upward. The elliptical horizontal plate at the bottom of the connecting column 404 will contact the inner wall of the rotating column 405. The displacement change generated during its rotation will drive the rotating column 405 to rotate synchronously. The rotation of the rotating column 405 will drive the fixed plate 406 to move. The fixed plate 406 will drive the moving plate 408 to move through the connecting plate 407. The moving plate 408 will then drive the arc plate 409 to guide the water along the telescopic rod 410. The horizontal movement causes multiple sets of arc plates 409 to move outward. When they move to a certain extent, the inner side of the motor housing is placed into the outer arc surface of the arc plate 409 to complete the installation. After the motor housing is fixed, the cylinder on the right side of the front of the positioning table 2 is activated, pushing the adjustment mechanism 4 to move back and forth. At the same time, the electric telescopic rod 3 on the front side of the top of the worktable 1 is equipped with a grinding disc or sandpaper. The electric telescopic rod 3 drives the grinding disc or sandpaper to approach the motor housing. During the process of the adjustment mechanism 4 driving the motor housing to move back and forth, the surface of the motor housing is polished.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
