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

[0020] In the technical solution of the present invention, the front and rear ends of the rotating shaft are respectively clamped with an outer ring that is rotatably connected to the inner wall of the fixed bottom frame.

[0022] On the other hand, the present invention provides a method for clamping components with an adjustable structure for motor assembly, using the above-mentioned component clamping device with an adjustable structure for motor assembly, comprising the following steps:

[0023] S1. First, the operator places the motor base on the conveyor belt in the conveyor device, and then places different parts in the component placement racks in several placement mechanisms in sequence according to the assembly order;

[0024] S2. Next, the operator starts the telescopic cylinder in the clamping device to drive the mobile platform as a whole to move toward the placement mechanism. At this time, the rotating gear contacts the fixed rack and rotates, driving the rotating gear and the wheel top frame to rotate 180°.

[0025] S3, as the mobile platform continues to move, the sliding frame is squeezed and moves to the right, and the outer rack on its outer wall drives the docking gear to rotate;

[0026] S4. After the docking gear rotates, the dial is driven to rotate, and the lever on the dial then drives the groove wheel to rotate 180°. The upper extension shaft rotates with the groove wheel, and drives the rotating platform to rotate 180°, so that the component placement rack for fixing the components faces the clamping device;

[0027] S5. Subsequently, the hydraulic clamp in the clamping device is started to clamp the motor parts, and then the mobile platform is driven to move toward the conveyor belt of the conveying device through the telescopic cylinder again. The wheel top frame will flip over as the rotating gear contacts the fixed rack again;

[0028] S6, after the hydraulic clamp moves the motor components to the top of the motor base, the drive motor is started to drive the screw rod to rotate, and the motor components on the hydraulic clamp are inserted into the inside of the motor base;

[0029] S7. Subsequently, control the hydraulic fixture to release the motor components, control the driving motor to restore the position of the hydraulic fixture, and repeat the above operations to re-clamp the new motor components.

[0030] S8. During the process of the moving platform moving towards the right, the moving cross plate inside it will pull the pulling rope, drive the outer sleeve ring to rotate, and drive the rotating shaft to rotate, thereby driving the internal structure of the docking part to rotate through the worm.

[0031] S9. When the worm gear in the docking part rotates counterclockwise along with the worm, the ratchet wheel inside it rotates counterclockwise accordingly, and through the docking shaft, drives the transport roller in the conveying device to rotate counterclockwise, and moves the motor base to the lower part of the adjacent clamping device in front.

[0032] S10. Subsequently, after all the motor components are assembled, the operator fixes the assembled motor with bolts at the front end of the conveying device.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0034] 1. The component clamping device with an adjustable structure and its method for motor assembly can directly replace the component placement rack with modular design in the placement mechanism according to the models of different components, and adjust the height of the hydraulic fixture to change the clamping position, so that the overall structure can meet the assembly work of motors of different models, and ensure the stability during the transportation of components.

[0035] 2. The component clamping device with an adjustable structure and its method for motor assembly can drive the moving platform to move left and right by the telescopic cylinder, and through the flipping device and the driving mechanism, realize the clamping, insertion of components and the automatic movement of the conveyor belt. While saving equipment investment, the entire production process becomes more compact and efficient, and reduces the dependence on manual skills. Description of the Drawings

[0056] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0057] See also Figures 1 - 13 As shown, this embodiment provides a technical solution:

[0058] A component clamping device with an adjustable structure for motor assembly, comprising a conveying device 100 for conveying a motor base, a plurality of fixed platforms 200 regularly arranged on the right side of the conveying device 100, a clamping device 300 capable of moving on the top surface of the fixed platform 200, a placement mechanism 400 for placing components, a flipping device 500 for driving the internal structure of the placement mechanism 400 to rotate as the clamping device 300 moves, and a driving mechanism 600 for driving the conveying device 100 to transport;

[0059] In the present invention, the fixed platform 200 includes a fixed bottom frame 210, a fixed top plate 230 providing a mobile platform for the clamping device 300, and a fixed rack 240 disposed above the fixed bottom frame 210 for interfering with the internal structure of the clamping device 300;

[0060] Specifically, a partition plate 220 is integrally formed inside the fixed bottom frame 210 , a limiting slide groove 231 is provided on the top surface of the fixed top plate 230 and a placement groove 232 connected to the limiting slide groove 231 is provided inside, and a fixed rack 240 is clamped and fixed to the outer wall of the fixed top plate 230 .

[0061] Furthermore, the partition plate 220 in the fixed bottom frame 210 is used to provide a rotation range for the structure in the driving mechanism 600, the limiting slide groove 231 on the fixed top plate 230 is used to provide a placement platform for the clamping device 300, and the placement groove 232 is used to provide a placement range for the structure in the flipping device 500.

[0062] In this embodiment, Figures 5 - 7As shown in the figure, the clamping device 300 includes a moving platform 310 that can move left and right on the fixed top plate 230, a rotating gear 320 rotatably connected to the inside of the moving platform 310, a wheel top frame 330 that rotates as the rotating gear 320 rotates, and a hydraulic fixture 360 that can move up and down outside the wheel top frame 330;

[0063] Specifically, the moving platform 310 includes a moving plate body 311 slidably connected to the inside of the limit chute 231. A rotating groove 3110 is formed on the top surface of the moving platform 310. Grooves are formed on the front and rear end walls of the rotating groove 3110 of the moving platform 310. The moving platform 310 further includes a limit slider 312 integrally formed at the left corner of the moving plate body 311, two positioning protrusions 313 slidably connected to the grooves of the rotating groove 3110, a first compression 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 moving cross plate 315 clamped and fixed below the moving plate body 311. The elastic force provided by the first compression spring 314 can push the positioning protrusion 313 towards the center of the rotating groove 3110.

[0064] Furthermore, the rotating gear 320 is rotatably connected to the inside of the rotating groove 3110. Two symmetrically arranged positioning grooves adapted to the size of the positioning protrusion 313 are formed on the outer side wall of the central rod of the rotating gear 320. The rotating gear 320 meshes with the fixed rack 240. The wheel top frame 330 is fixedly connected to the top surface of the rotating gear 320 by bolts. A driving motor 340 is fixed on the top surface of the wheel top frame 330. The output shaft of the driving motor 340 is coaxially connected to a lead screw 350 with the bottom end rotatably connected to the bottom surface inside the wheel top frame 330. The bracket of the hydraulic fixture 360 is slidably connected to the inside of the wheel top frame 330 and is threadedly connected to the lead screw 350. A telescopic cylinder 370 with a telescopic rod fixed to the bottom surface of the right end of the fixed bottom frame 210 by bolts and the moving cross plate 315 fixed by bolts.

[0065] Furthermore, control the telescopic cylinder 370 in the clamping device 300 to drive the entire moving platform 310 to move towards the placing mechanism 400. At this time, when the rotating gear 320 contacts the fixed rack 240, it rotates, driving the rotating gear 320 and the wheel top frame 330 to rotate 180°. Start the hydraulic fixture 360 in the clamping device 300 to clamp the motor parts. Then, through the telescopic cylinder 370 again, drive the moving platform 310 to move towards the conveyor belt of the conveyor device 100. The wheel top frame 330 will flip during the process of the rotating gear 320 contacting the fixed rack 240 again. After the hydraulic fixture 360 moves the motor parts above the motor base, start the driving motor 340 to drive the lead screw 350 to rotate, and insert the motor parts on the hydraulic fixture 360 into the inside of the motor base.

[0066] In this embodiment, as Figures 8 - 10 shown, the placement mechanism 400 includes a lifting bracket 410 and a component placement rack 420 that temporarily fixes components by magnetic attraction;

[0067] Specifically, the lifting bracket 410 is fixedly connected to the top surface of the fixed top plate 230 by bolts. A rotating round hole is provided at the center of the top plate of the lifting bracket 410, and a slot for convenient and quick insertion is provided on the bottom surface of the component placement rack 420.

[0068] 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, so as to ensure that half of the space of the components can be inserted into the interior of the component placement rack 420.

[0069] In this embodiment, as Figure 11 shown, the flipping device 500 includes a sliding frame 510 that moves as the moving platform 310 moves, a second compression spring 520 that uses its own elastic force to reset the displaced sliding frame 510, a docking gear 530 that rotates as the sliding frame 510 moves, and a rotating platform 570 that makes a 180° turn through the rotation of the docking gear 530;

[0070] Specifically, the sliding frame 510 is slidably connected to the inside of the placement groove 232. An outward protruding strip 511 is integrally formed at the left end of the sliding frame 510, and an outer rack 512 meshing with the docking gear 530 is integrally formed on the outer side wall of the right end of the sliding frame 510. One end of the second compression spring 520 abuts against the sliding frame 510, and the other end abuts against the right end wall of the placement groove 232.

[0071] 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 central rod. A grooved wheel 550 is provided at the rear of the dial 540. A top extension shaft 560 rotatably connected to the top surface of the fixed top plate 230 is clamped and fixed inside the grooved wheel 550. The top of the top extension shaft 560 is clamped and fixed with a rotating platform 570 rotatably connected to the rotating round hole of the top plate in the lifting bracket 410. The insertion plate on the top surface of the rotating platform 570 is adapted to the slot at the bottom of the component placement rack 420.

[0072] 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.

[0073] In this embodiment, Figures 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;

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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 multiple groups of clamping devices 300.

[0079] A method for clamping components 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:

[0080] 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;

[0081] 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°.

[0082] 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;

[0083] 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;

[0084] S5. Subsequently, start the hydraulic clamp 360 in the clamping device 300. After clamping the motor components, drive the moving platform 310 towards the conveyor belt direction of the conveying device 100 again through the telescopic cylinder 370. The wheel top frame 330 will flip during the process of the rotating gear 320 contacting the fixed rack 240 again;

[0085] S6. After the hydraulic clamp 360 moves the motor components above the motor base, start the drive motor 340 to drive the lead screw 350 to rotate, so that the motor components on the hydraulic clamp 360 are inserted into the interior of the motor base;

[0086] S7. Then, control the hydraulic clamp 360 to release the motor components, and control the drive motor 340 to restore the position of the hydraulic clamp 360, and repeat the above operations to clamp new motor components again;

[0087] S8. During the process of the moving platform 310 moving towards the right, the moving cross plate 315 inside it will pull the pulling rope 650, drive the outer sleeve 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;

[0088] S9. When the worm gear 671 in the docking part 670 rotates counterclockwise along with the worm 660, the ratchet wheel 673 inside it rotates counterclockwise accordingly, and drives the transport roller in the conveying device 100 to rotate counterclockwise through the docking shaft 674, so as to move the motor base below the adjacent clamping device 300 in front;

[0089] S10. Subsequently, after all the motor components are assembled, the operator fixes the assembled motor with bolts at the front end of the conveying device 100.
