Description

Technical Field

[0001] The present invention relates to the technical field of motor assembly, in particular to a component clamping device with an adjustable structure for motor assembly and a method thereof. Background Art

[0002] The component clamping device with an adjustable structure for motor assembly is an advanced tool designed specifically for motor assembly. The device drives the rotating telescopic rod through a hydraulic cylinder to achieve flexible extension and angle adjustment of the clamping claws. The tip of the clamping claw has a built-in rubber pad to effectively increase the friction with the components, ensuring that the components are firmly clamped during assembly to avoid loosening.

[0003] The patent application number CN202222971057.9 discloses a component clamping device with an adjustable structure for motor assembly, including a combination mechanism, a sliding mechanism, a rotating mechanism, a clamping mechanism and a rubber replacement mechanism. The sliding mechanism is arranged on both sides of the top of the combination mechanism, and the clamping mechanism is arranged on the middle side of the sliding mechanism, and the rubber replacement mechanism is arranged at the tip of the clamping mechanism. In the component clamping device with an adjustable structure for motor assembly, the clamping claw extends the rotating telescopic rod through the power of the hydraulic cylinder, and then uses the rotating telescopic rod's own rotatable structure to adjust the angle, which can avoid the phenomenon of loose clamping during assembly.

[0004] In the field of motor assembly, many traditional fixtures are not integrated with modular design. When different models or specifications of parts need to be adapted, the fixtures often have to be replaced as a whole or cumbersome adjustment procedures have to be performed, which increases the difficulty and cost of operation. In addition, when assembling motors, the existing parts clamping devices usually rely on multiple independent drive systems or increase manual intervention for key links such as parts clamping, precise insertion, and automatic movement of conveyor belts, resulting in lengthy processes and long waiting times, which also restricts the further improvement of production automation levels. In view of this, we propose a parts clamping device with an adjustable structure for motor assembly and a method thereof. Summary of the invention

The movable platform 310 also includes a limiting sliding block 312 integrally formed at the left corner of the movable plate body 311, two positioning protrusions 313 slidably connected to the inside of the groove of the rotating groove 3110, a first pressure spring 314 with one end connected to the groove wall of the rotating groove 3110 and the other end connected to the positioning protrusion 313, and a movable cross plate 315 clamped and fixed under the movable plate body 311, the elastic force provided by the first pressure spring 314 can push the positioning protrusion 313 to the center of the rotating groove 3110.

[0023] Furthermore, the rotating gear 320 is rotatably connected to the inside of the rotating groove 3110, and two symmetrically arranged positioning grooves that are adapted to the size of the positioning protrusion 313 are opened on the outer side wall of the center rod of the rotating gear 320.

The fixed bottom frame 210 is fixed to the bottom surface of the right end with a telescopic rod and a telescopic cylinder 370 fixed by bolts to the movable cross plate 315.

[0024] Furthermore, the telescopic cylinder 370 in the clamping device 300 is controlled to drive the mobile platform 310 to move as a whole toward the placement mechanism 400. At this time, the rotating gear 320 rotates after contacting the fixed rack 240, and drives the rotating gear 320 and the wheel top frame 330 to rotate 180°. The hydraulic clamp 360 in the clamping device 300 is started to clamp the motor components. The telescopic cylinder 370 is used again to drive the mobile platform 310 to move toward the conveyor belt direction of the conveying device 100. The wheel top frame 330 will flip over as the rotating gear 320 contacts the fixed rack 240 again. After the hydraulic clamp 360 moves the motor components to the top of the motor base, the drive motor 340 is started to drive the screw rod 350 to rotate, and the motor components on the hydraulic clamp 360 are inserted into the inside of the motor base.

[0025] In this embodiment, Figure 8-Figure 10 As shown, the placement mechanism 400 includes a lifting bracket 410 and a component placement rack 420 for temporarily fixing components by magnetic attraction; Specifically, the lifting bracket 410 is fixedly connected to the top surface of the fixed top plate 230 by bolts, a rotating circular hole is opened in the center of the top plate of the lifting bracket 410, and a slot for convenient and quick plug-in is opened on the bottom surface of the component placement frame 420.

[0026] Furthermore, the lifting bracket 410 is used to raise the height of the component placement rack 420 , and the placement rack of the component placement rack 420 can be customized according to the sizes of different components to ensure that half of the space of the component can be inserted into the interior of the component placement rack 420 .

[0027] In this embodiment, Fig.11 As shown, the flipping device 500 includes a sliding frame 510 that moves with the movement of the moving platform 310, a second pressure spring 520 for resetting the displaced sliding frame 510 by its own elastic force, a docking gear 530 that rotates with the movement of the sliding frame 510, and a rotating platform 570 that turns 180° by the rotation of the docking gear 530; Specifically, the sliding frame 510 is slidably connected to the inside of the placement groove 232, the left end of the sliding frame 510 is integrally formed with an outward protruding strip 511, and the outer wall of the right end of the sliding frame 510 is integrally formed with an outer frame rack 512 that meshes with the docking gear 530, and one end of the second pressure spring 520 is against the sliding frame 510, and the other end is against the right end groove wall of the placement groove 232.

[0028] Furthermore, the docking gear 530 is rotatably connected to the bottom surface of the placement groove 232 and a dial 540 is clamped and fixed above the center rod. A groove wheel 550 is provided on the rear side of the dial 540. The interior of the groove wheel 550 is clamped and fixed with an upward extension shaft 560 rotatably connected to the top surface of the fixed top plate 230. The top end of the upward extension shaft 560 is clamped and fixed with a rotating platform 570 rotatably connected to the rotating circular hole of the top plate of the lifting bracket 410. The plug plate on the top surface of the rotating platform 570 is adapted to the slot at the bottom of the component placement rack 420.

[0029] Furthermore, as the moving platform 310 continues to move, the sliding frame 510 is squeezed and moves to the right, and the outer frame rack 512 on its outer wall drives the docking gear 530 to rotate. After the docking gear 530 rotates, it drives the dial 540 to rotate, and the lever on the dial 540 then drives the groove wheel 550 to rotate 180°. The upper extension shaft 560 rotates together with the groove wheel 550, and drives the rotating platform 570 to rotate 180°, so that the component placement rack 420 for fixing the components faces the clamping device 300.

[0030] In this embodiment, Figure 12-13 As shown, the driving mechanism 600 includes a rotating shaft 610 that rotates clockwise as the moving platform 310 moves, a volute spring 640 that drives the rotating shaft 610 to rotate counterclockwise by its own elastic force, and a docking portion 670 whose internal structure rotates as the rotating shaft 610 rotates; Specifically, the docking portion 670 includes a worm gear 671 , a ratchet wheel 673 that rotates as the worm gear 671 rotates counterclockwise, and a docking shaft 674 that drives the internal transport rollers of the conveying device 100 to rotate.

[0031] Furthermore, the front and rear ends of the rotating shaft 610 are respectively clamped with an outer ring 620 rotatably connected to the inner wall of the fixed bottom frame 210, and a worm 660 is sleeved at the center of the outer wall of the rotating shaft 610. The outer end of the spiral spring 640 is welded to the inner ring wall of the outer ring 620, and the inner end is welded with a fixed rod 630 clamped on the inner wall of the fixed bottom frame 210. The outer side of the outer ring 620 is wrapped with a pulling rope 650, and the end of the pulling rope 650 is adhered to the outer wall of the movable horizontal plate 315.

[0032] Furthermore, the worm wheel 671 is rotatably connected to the outer wall of the partition plate 220 through the wheel center rod 675 on the rear side wall, and a plurality of ratchets 673 that interfere with the ratchet 673 are rotatably connected to the inner ring wall of the worm wheel 671. The ratchet 673 is fixedly connected to the end of the docking shaft 674 through a bayonet pin, and the end of the docking shaft 674 extends to the interior of the conveying device 100 and is fixedly engaged with the transport roller.

[0033] Furthermore, when the moving platform 310 moves toward the right, the moving cross plate 315 inside it will pull the pulling rope 650, drive the outer ring 620 to rotate, and drive the rotating shaft 610 to rotate, thereby driving the internal structure of the docking part 670 to rotate through the worm 660. When the worm wheel 671 in the docking part 670 rotates counterclockwise with the worm 660, the ratchet 673 inside it rotates counterclockwise therewith, and through the docking shaft 674, the transport roller in the conveying device 100 is driven to rotate counterclockwise, and the motor base is moved to the bottom of the adjacent clamping device 300 in front. When the moving platform 310 moves toward the conveying device 100, the elastic force of the spiral spring 640 drives the outer ring 620 to rotate, and the pulling rope 650 is wound up. At this time, the worm wheel 671 will rotate clockwise, and the pawl 672 will rotate along the direction of the ratchet 673, and the ratchet 673 and the docking shaft 674 remain fixed.

[0034] Finally, it should be noted that when the overall device is actually used, a group of telescopic cylinders 370 can be used to drive the movement of the mobile platforms 310 in the multiple groups of clamping devices 300.

[0035] A method for clamping parts with an adjustable structure for motor assembly, using the above-mentioned component clamping device with an adjustable structure for motor assembly, comprises the following steps: S1. First, the operator places the motor base on the conveyor belt in the conveyor device 100, and then places different components in the component placement racks 420 in the plurality of placement mechanisms 400 in sequence according to the assembly order; S2. Next, the operator activates the telescopic cylinder 370 in the clamping device 300 to drive the mobile platform 310 to move as a whole toward the placement mechanism 400. At this time, the rotating gear 320 contacts the fixed rack 240 and rotates, driving the rotating gear 320 and the wheel top frame 330 to rotate 180°. S3, as the moving platform 310 continues to move, the sliding frame 510 is squeezed and moves to the right, and the outer rack 512 on the outer wall drives the docking gear 530 to rotate; S4, after the docking gear 530 rotates, the dial 540 is driven to rotate, and the lever on the dial 540 then drives the groove wheel 550 to rotate 180°, and the upper extension shaft 560 rotates together with the groove wheel 550, and drives the rotating platform 570 to rotate 180°, so that the component placement rack 420 for fixing the components faces the clamping device 300; S5. Subsequently, the hydraulic clamp 360 in the clamping device 300 is started to clamp the motor components, and then the mobile platform 310 is driven to move toward the conveyor belt direction of the conveying device 100 by the telescopic cylinder 370 again. The wheel top frame 330 will flip over as the rotating gear 320 contacts the fixed rack 240 again. S6, after the hydraulic clamp 360 moves the motor components to the top of the motor base, the drive motor 340 is started to drive the screw rod 350 to rotate, so that the motor components on the hydraulic clamp 360 are inserted into the inside of the motor base; S7, then, control the hydraulic clamp 360 to release the motor component, and control the drive motor 340 to drive the hydraulic clamp 360 to restore the position, and repeat the above operation to clamp the new motor component again; S8. When the mobile platform 310 moves to the right, the mobile horizontal plate 315 inside it pulls the pulling rope 650, driving the outer ring 620 to rotate, and driving the rotating shaft 610 to rotate, thereby driving the internal structure of the docking part 670 to rotate through the worm 660; S9, when the worm wheel 671 in the docking portion 670 rotates counterclockwise along with the worm 660, the ratchet wheel 673 inside the worm wheel 671 rotates counterclockwise therewith, and drives the transport roller in the conveying device 100 to rotate counterclockwise through the docking shaft 674, and moves the motor base to the bottom of the adjacent clamping device 300 in front; S10. Subsequently, after all the motor parts are assembled, the operator at the front end of the conveying device 100 performs final fixation on the assembled motor by means of bolts.
