Description
Technical Field
[0001] This utility model relates to the field of motor assembly technology, and in particular to a technology for processing and fixing a motor fan cover. Background Technology
[0002] The machining of the mounting holes for the fan cover determines the overall dimensions of the motor. In terms of production and processing, motors are divided into many frame sizes based on different center heights, resulting in various fan cover specifications. Building a fan cover machining station based on multiple frame sizes would occupy a lot of factory space. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention provides a motor fan cover processing and fixing device, characterized in that it includes a base, a lifting seat, a rotating disk and a fixing disk; The lower end of the fixed plate is fixed with a threaded rod along the axial direction. The fixed plate has four straight slots that extend from the inside to the outside along the radial direction of the fixed plate and are open at the outer end. The slots are through slots that pass through from top to bottom. The four slots are symmetrically arranged around the center of the fixed plate. The rotating disk has four arc-shaped grooves that extend from the inside out and are closed at both the inner and outer ends. The arc-shaped grooves are upward-opening grooves, and the four arc-shaped grooves are symmetrically arranged around the center of the rotating disk. The upper end of the lifting seat is rotatably connected to the rotating disk, and the threaded rod passes through the rotating disk and the lifting seat from top to bottom. The rod body is threadedly connected to the lifting seat, and the lower end of the threaded rod is threadedly connected to the base. Each of the four slots has a movable sliding block, and a downward-protruding sliding post is fixed on the sliding block. The lower ends of the four sliding posts extend into the four arc-shaped slots respectively. The lower ends of the four sliding posts are equipped with bearings, and the bearings at the lower ends of the sliding posts are clearance-fitted with the slot walls of the arc-shaped slots. Each sliding block has a positioning block fixed at its upper end. The positioning block has a groove in the middle for placing the motor fan cover, and a positioning hole at the top for the punch to pass through.
[0005] Furthermore, the lifting platform is equipped with a handle.

[0007] Furthermore, the slot on the fixed plate is a ball bearing groove.
[0008] The motor fan cover processing and fixing device provided by this utility model adopts a purely mechanical structure and is manually operated. By rotating the lifting seat, the sliding blocks on the rotating disk can be moved up and down, thereby adjusting the height of the punching holes in the fan cover. Driving each sliding block to move in the arc groove on the rotating disk can make the sliding blocks move closer or further away from the center of the rotating disk, thereby matching fan covers of various sizes.

Detailed Implementation
[0010] The embodiments of this utility model are described in further detail below with reference to the accompanying drawings. However, these embodiments are not intended to limit this utility model. Any similar structures or variations thereof that adopt this utility model should be included in the protection scope of this utility model. The commas in this utility model all indicate the relationship between and.
[0011] like Figures 1-4 As shown in the figure, the motor fan cover processing and fixing device provided in this embodiment of the present invention includes a base 5, a lifting seat 1, a rotating disk 2 and a fixing disk 4; The lower end of the fixed disk 4 is fixed with a threaded rod 41 along the axial direction. The fixed disk 4 has four straight slots 42 that extend from the inside to the outside along the radial direction of the fixed disk and are open at the outer end. The slots 42 are through slots that pass through from top to bottom. The four slots 42 are symmetrically arranged around the center of the fixed disk. The rotating disk 2 has four arc-shaped grooves 21 extending from the inside out and closed at both the inner and outer ends. The arc-shaped grooves 21 are upward-opening grooves, and the four arc-shaped grooves 21 are symmetrically arranged around the center of the rotating disk. The upper end of the lifting seat 1 is rotatably connected to the rotating disk 2. The threaded rod 41 passes through the rotating disk 2 and the lifting seat 1 from top to bottom. The rod body of the threaded rod 41 is threadedly connected to the lifting seat 1, and the lower end of the threaded rod 41 is threadedly connected to the base 5. Each of the four slots 42 has a movable sliding block 3. A downwardly protruding sliding column 31 is fixed on the sliding block 3. The lower ends of the four sliding columns 31 extend into the four arc-shaped slots 21 respectively. The lower ends of the four sliding columns 31 are all equipped with bearings (not shown in the figure), and the bearings at the lower ends of the sliding columns are clearance-fitted with the groove walls of the arc-shaped slots 21. A positioning block 32 is fixed at the upper end of each sliding block 3. The positioning block 32 has a groove 33 in the middle for placing the motor fan cover, and a positioning hole 34 for the punch to pass through is opened at the upper part of the positioning block 32.
[0012] In this embodiment of the utility model, the lifting seat 1 is provided with a handle 11, the side arm of the rotating disk 2 is provided with a rotating protrusion 22, and the slot 42 on the fixed disk 4 is a ball groove.
[0013] The device provided in this embodiment of the utility model is used for punching holes in a motor fan cover. When using the device, the operator should operate it according to the size of the motor fan cover. When it is necessary to reduce the size of the fan cover, rotate the rotating disk 2 counterclockwise so that the inner end of each arc groove 21 moves closer to the sliding column 31 in its respective groove. Each sliding column 31 is affected by the thrust of the outer groove wall of the corresponding arc groove 21 and moves radially inward along the slot 42 on the fixed disk 4, thereby reducing the radius of the motor fan cover placement area. When it is necessary to expand the matching size of the fan cover, rotate the rotating disk 2 clockwise so that the outer end of each arc groove 21 moves closer to the sliding column 31 in its respective groove. Each sliding column 31 is affected by the thrust of the inner groove wall of the corresponding arc groove 21 and moves radially outward along the slot 42 on the fixed disk 4, thereby expanding the radius size of the motor fan cover placement area. When it is necessary to adjust the height of the punching hole in the hood, rotate the lifting seat 1 to move the rotating disk 2 up or down, and the sliding block 3 will also move up or down accordingly. The punching height varies according to the height of the positioning hole 34 of each positioning block 32. After the fan cover matching size and punching height are adjusted, the motor fan cover is placed into the groove 33 of each positioning block 32, and the external punching cylinder 6 can be started to align the positioning hole 34 at each positioning block 32 position to perform punching.
