Description

Technical Field

[0001] The utility model relates to the technical field of trimming equipment, and more specifically, to a trimming device for polymer wheels. Background Art

[0002] A wheel is a circular rolling object made of different materials. Wheels are very useful in transportation and are one of the important inventions of mankind. Through rolling, wheels can greatly reduce the friction coefficient with the contact surface, enabling people to move objects much heavier than their own weight.

[0003] With the development of technology, the application of polymer materials is becoming more and more extensive.

[0036] Among them, the expansion mechanism includes moving blocks 6, the number of the moving blocks 6 is two, the outer surfaces of the two moving blocks 6 are respectively movably connected with the inside of the short grooves 5, threaded rods 7 are respectively threadedly sleeved inside the two moving blocks 6, the bottom ends of the moving blocks 6 are fixedly installed with first friction blocks 8, the number of the first friction blocks 8 is two, the outer surfaces of the two first friction blocks 8 are respectively movably connected with the inside of the grinding block 4, the bottom ends of the two first friction blocks 8 are respectively movably connected with the top end of the polymer wheel body 2, and second friction blocks 9 are respectively fixedly installed at the bottom ends of the two opposite ends of the two first friction blocks 8.

[0037] Since the two moving blocks 6 are respectively threadedly sleeved on the two threaded rods 7, when the two threaded rods 7 rotate, they will drive the two moving blocks 6 to move. Due to the limiting effect of the two short grooves 5, at this time, the two moving blocks 6 will drive the two first friction blocks 8 to move towards each other. Immediately afterwards, the two first friction blocks 8 will drive the two second friction blocks 9 to move towards each other, so that the polymer wheel body 2 of various sizes can be polished.

[0038] Among them, the driving mechanism includes:

[0039] A fixed block 10, the bottom end of the fixed block 10 is fixedly connected to the top end of the polishing block 4, and both the left and right sides of the fixed block 10 are movably connected to the outer surface of the threaded rod 7;

[0040] A biaxial motor 11, the outer surface of the biaxial motor 11 is fixedly sleeved inside the fixed block 10, and the other end of the output shaft of the biaxial motor 11 is fixedly sleeved with a rotating shaft 12.

[0041] When the biaxial motor 11 operates, at this time, the two rotating shafts 12 will rotate, and then the two rotating shafts 12 will drive the two threaded rods 7 to rotate.

[0042] Among them, a fixed frame 13 is fixedly installed at the top end of the base 1, a driving motor 14 is fixedly installed at the top end of the fixed frame 13, and the other end of the output shaft of the driving motor 14 is fixedly sleeved with a short shaft 15.

[0045] When the air cylinder 16 operates, at this time, the bottom end of the air cylinder 16 will drive the entire fixed block 10 to move up and down. When the short shaft 15 rotates, at this time, the air cylinder 16 will rotate under the drive of the short shaft 15. At this time, the air cylinder 16 will drive the entire fixed block 10 to rotate. Subsequently, the polishing block 4, the first friction blocks 8 and the second friction blocks 9 will polish and trim the polymer wheel body 2 during rotation.

[0046] Among them, a power motor 17 is fixedly installed at the bottom end inside the base 1, and the other end of the output shaft of the power motor 17 is fixedly sleeved with a lead screw 18, and the top end of the lead screw 18 is movably connected to the top end inside the base 1.

[0047] When the power motor 17 operates, at this time the lead screw 18 will rotate.

[0048] Among them, a lifting plate 19 is threadedly sleeved on the outer surface of the lead screw 18, and a first hinge block 20 is fixedly installed at the top end of the lifting plate 19.

[0049] Since the outer surface of the lead screw 18 is threadedly sleeved with the inside of the lifting plate 19, when the lead screw 18 rotates, it will drive the lifting plate 19 to move downward, and then the lifting plate 19 will simultaneously drive the four first hinge blocks 20 to move downward.

Due to the limiting effect inside the four limiting grooves 3, at this time the four clamping blocks 24 will move inward, and then the four clamping blocks 24 will clamp and fix the polymer wheel body 2 during the inward movement.

[0056] Among them, the grinding block 4, the first friction block 8 and the second friction block 9 are all made of metal, and the bottom ends of the grinding block 4, the first friction block 8 and the second friction block 9 are all rough.

[0057] Due to the design of the grinding block 4, the first friction block 8 and the second friction block 9, the efficiency of grinding and trimming the polymer wheel body 2 can be improved.

[0058] The working principle and usage process of the present utility model:

[0059] First, the operator places the polymer wheel body 2 on the top of the base 1. Then the operator starts the power motor 17. At this time, the lead screw 18 will rotate. Since the outer surface of the lead screw 18 is threadedly sleeved with the internal thread of the lifting plate 19, when the lead screw 18 rotates, it will drive the lifting plate 19 to move downward. At this time, the four first hinge blocks 20 will move downward under the drive of the lifting plate 19. At this time, the four first hinge blocks 20 will respectively drive the four moving rods 21 to move. At the same time, the other ends of the four moving rods 21 will respectively drive the four second hinge blocks 22 to move. At this time, the four second hinge blocks 22 will respectively drive the four movable blocks 23 to move. Then, the four movable blocks 23 will respectively drive the four clamping blocks 24 to move. Due to the design of the four limiting grooves 3, the movement of the four clamping blocks 24 will be limited. At this time, the four clamping blocks 24 will move inward along the inside of the four limiting grooves 3. At this time, the four clamping blocks 24 will clamp the polymer wheel body 2 during the inward movement, thus realizing the function of automatically clamping and fixing polymer wheel bodies 2 of different sizes.

[0060] Subsequently, the operator starts the air cylinder 16. At this time, the bottom end of the air cylinder 16 will drive the fixed block 10 to move downward. Then, the fixed block 10 will drive the grinding block 4 as a whole to move downward. When the bottom end of the grinding block 4 contacts the top end of the polymer wheel body 2, the bottom end of the first friction block 8 will also contact the top end of the polymer wheel body 2. At this time, the operator starts the double-shaft motor 11. At this time, the two rotating shafts 12 will rotate. Then, the two threaded rods 7 will rotate under the drive of the two rotating shafts 12. Since the interiors of the two moving blocks 6 are respectively threadedly sleeved with the outer surfaces of the two threaded rods 7, the two threaded rods 7 will drive the two moving blocks 6 to move during the rotation. Due to the design inside the two short grooves 5, the movement of the two moving blocks 6 will be limited, so that the two moving blocks 6 can only move left and right. At this time, the two moving blocks 6 will move towards each other under the drive of the two threaded rods 7. At the same time, the two moving blocks 6 will drive the two first friction blocks 8 to move towards each other. At this time, the two second friction blocks 9 will move towards each other under the drive of the two first friction blocks 8. When the opposite sides of the two second friction blocks 9 contact the outer surface of the polymer wheel body 2 during the inward movement, the two second friction blocks 9 will be able to polish the outer surface of the polymer wheel body 2, thus realizing the function of trimming the edges of polymer wheels of various sizes. At this time, the operator starts the drive motor 14. At this time, the short shaft 15 will drive the air cylinder 16 as a whole to rotate. At this time, the grinding block 4, the two first friction blocks 8 and the two second friction blocks 9 will polish and trim the outer surface of the polymer wheel body 2 during the rotation.
