[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1 、 Figure 2 and Figure 4 A motor pulley mounting device includes a base 1, a shell 2 is fixedly connected to the top of the base 1, a through-hole is provided on the top of the shell 2, a fixing platform 3 is slidably connected to the inner side wall of the shell 2, a clamping structure 4 is provided inside the fixing platform 3, and a calibration structure 5 is provided on the outer side wall of the fixing platform 3. There are two calibration structures 5, which are respectively located on the left side and the bottom of the fixing platform 3;

[0028] The clamping structure 4 includes an outer ring 401 fixedly connected to the inner side wall of the fixed platform 3, the inner side wall of the outer ring 401 is slidably connected to the inner ring 402, the inner ring 402 is located inside the outer ring 401, and the outer side wall of the inner ring 402 is rotatably connected to the clamping rod 403, and three clamping rods 403 are provided. The three clamping rods 403 are all located on the same side of the inner ring 402 and the outer ring 401, and one end of the three clamping rods 403 away from the center point of the inner ring 402 is rotatably connected to the outer side wall of the outer ring 401, and the outer side wall of the inner ring 402 is fixedly connected to the protrusion 40 5. A spring 406 is fixedly connected to the outer wall of the protrusion 405. The spring 406 is in an arc shape. The end of the spring 406 away from the protrusion 405 is fixedly connected to the outer ring 401. A handle 404 is fixedly connected to the outer wall of the inner ring 402. The outer wall of the handle 404 is slidably connected to the top of the housing 2. The top of the handle 404 is set in an arc shape. A through groove 407 is formed on the outer wall of the outer ring 401. The protrusion 405 is slidably connected to the outer ring 401 through the through groove 407. The protrusion 405 is located inside the through groove 407.

[0029] When in use, a force is applied to the handle 404 to the left. Since the handle 404 is fixedly connected to the inner ring 402, the handle 404 drives the inner ring 402 to rotate counterclockwise inside the outer ring 401. At the same time, the protrusion 405 stretches the spring 406. Since the three clamping rods 403 are all rotatably connected to the inner ring 402 and the three clamping rods 403 are all rotatably connected to the through groove 407, the three clamping rods 403 are respectively rotated clockwise with the rotation connection between the inner ring 402 and the clamping rod 403 as the center point, and the The pulley is placed inside the fixed platform 3, and the force applied to the pull handle 404 is removed. Since the protrusion 405 loses the force to stretch the spring 406, the spring 406 contracts, causing the inner ring 402 to rotate clockwise inside the through groove 407, and then the three clamping rods 403 are respectively rotated counterclockwise with the hinge between the inner ring 402 and the clamping rod 403 as the center point, so that the ends of the three clamping rods 403 close to the center point of the inner ring 402 enter the groove of the pulley to clamp the pulley and prevent the pulley from falling off.

[0030] Reference Figure 3The calibration structure 5 includes a threaded rod 501 threadedly connected to the outer wall of the shell 2, the inner wall of the shell 2 is adapted to the outer wall of the threaded rod 501, and one end of the threaded rod 501 is rotatably connected to a moving rod 502, and the cross section of the moving rod 502 is set to an I-shape. The outer wall of the fixed platform 3 is provided with a moving groove 503, and the cross section of the moving groove 503 is set to a T-shape. The moving rod 502 is slidably connected to the fixed platform 3 through the moving groove 503. By rotating the threaded rod 501, the threaded rod 501 drives the fixed platform 3, so that the fixed platform 3 moves inside the shell 2. The cooperation of the moving rod 502 and the moving groove 503 can prevent the fixed platform 3 from getting stuck when moving inside the shell 2, thereby moving the fixed platform 3 to move the pulley inside the fixed platform 3 to a suitable position so that the center point of the pulley is aligned with the center of the motor.

[0031] Reference Figure 3 The outer wall of the moving rod 502 is fixedly connected to the limiting rod 504. There are four limiting rods 504. The four limiting rods 504 are respectively located at the two ends of the two moving rods 502. The outer walls of the four limiting rods 504 are all slidably connected to the outer shell 2, thereby limiting the moving rod 502 and preventing the fixed platform 3 from angular deviation.

[0032] Reference Figure 2 The three clamping rods 403 are fixedly connected to a rubber sleeve 408 at one end near the center point of the inner ring 402. There are three rubber sleeves 408, and the surfaces of the three rubber sleeves 408 are provided with textures to cushion the pulley and avoid wear caused by direct contact between the clamping rods 403 and the pulley.

[0033] Reference Figure 2 The three clamping rods 403 are distributed in a circular array with the center point of the inner ring 402 as the center, so that the clamping rods 403 apply force to the pulley evenly, making the clamping rods 403 clamp the pulley more firmly.

[0034] Reference Figure 3 The top of the base 1 is fixedly connected to a cylinder 6, the telescopic end of the cylinder 6 is fixedly connected to a movable seat 7, the movable seat 7 is located between the outer shell 2 and the cylinder 6, the top of the movable seat 7 is fixedly connected to a fixed seat 10, and the fixed seat 10 is located at the top center of the movable seat 7. The fixed seat 10 is driven by the movement of the movable seat 7, and then the motor inside the fixed seat 10 is driven to move, so that the pulley is installed on the motor.

[0035] Reference Figure 3The bottom of the movable seat 7 is fixedly connected with a T-block 8, the cross section of the T-block 8 is set to T-shape, the top of the base 1 is provided with a T-slot 9, the cross section of the T-slot 9 is set to T-shape, the T-block 8 is slidably connected to the base 1 through the T-slot 9, the T-block 8 is adapted to the T-slot 9, and the movable seat 7 is pushed by the cylinder 6, and the movable seat 7 drives the T-block 8 to slide in the T-slot 9, so that the motor above the movable seat 7 reaches the predetermined position.

[0036] Working principle: When in use, apply a leftward force to the handle 404, which drives the inner ring 402 to rotate counterclockwise inside the outer ring 401. At the same time, the protrusion 405 stretches the spring 406, and the three clamping rods 403 rotate clockwise with the rotation connection between the inner ring 402 and the clamping rod 403 as the center point. Place the pulley to be installed inside the fixed platform 3, remove the force applied to the handle 404, and the spring 406 contracts, so that the inner ring 402 rotates clockwise inside the through groove 407, thereby causing the three clamping rods 403 to rotate clockwise. Rotate counterclockwise with the hinge of the inner ring 402 and the clamping rod 403 as the center point, so that the three clamping rods 403, one end close to the center point of the inner ring 402, enter the groove of the pulley to clamp the pulley to prevent the pulley from falling off, and then place the motor in the fixed seat 10, rotate the two threaded rods 501 respectively, and the two threaded rods 501 respectively drive the fixing platform 3 to move up, down, left and right inside the shell 2. By adjusting the position of the fixing platform 3, the center point of the pulley is aligned with the center point of the motor, and the cylinder 6 is started to push the motor to install the pulley.
