[0002] A three-phase voltage stabilizer is a device used to stabilize voltage fluctuations. It stabilizes the power supply by compensating for voltage fluctuations, thereby protecting electrical equipment from performance failures caused by voltage anomalies. When assembling a three-phase voltage stabilizer, the most stable and convenient way to fix the brush base to the coil base is bolt assembly. The bolt assembly method is not only stable and reliable, but also simple to operate and flexible to disassemble and assemble, which facilitates the subsequent inspection and maintenance of the three-phase voltage stabilizer.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of 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 of 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.

[0030] Embodiment: A three-phase voltage stabilizer assembly device, see Figure 1-Figure 6 , including: an assembly table 1; a mounting frame 2 arranged in the middle of the assembly table 1, the coil 33 is loaded at a position on the assembly table 1 located on the left side of the mounting frame 2, and the brush base 34 is loaded at a position on the assembly table 1 located on the right side of the mounting frame 2; an arm 3 arranged on the mounting frame 2; a mounting disk 4 rotatably mounted at the end of the arm 3; a servo motor b20 fixedly mounted on the arm 3, the output end of the servo motor b20 is fixed to the mounting disk 4, and the servo motor b20 controls the rotation of the mounting disk 4; an assembly unit fixedly mounted on the mounting disk 4, the assembly unit is used to automatically assemble the screws 35 in each assembly hole between the coil 33 and the brush base 34, and a total of three groups of assembly units are arranged on the mounting disk 4.

[0031] The assembly unit includes: a servo motor a5 fixedly mounted on the lower part of the mounting plate 4, the servo motor a5 is fixed with a mounting plate, a cross shaft is fixedly mounted on the output end of the servo motor a5; a threaded barrel 6 slidably mounted on the cross shaft, the servo motor a5 controls the rotation of the threaded barrel 6 through the cross shaft, and the threaded barrel 6 can move relative to the servo motor a5 and maintain the control relationship of the servo motor a5 to the threaded barrel 6; a cutter head 7 rotatably mounted at the bottom of the threaded barrel 6, a magnetic material surface is provided on the outside of the cutter head 7, so that the cutter head 7 can magnetically attract the screw 35; a ratchet gear 8 fixedly mounted on the upper circumference of the cutter head 7; a sharp tooth 9 slidably mounted at the bottom of the threaded barrel 6, a spring for resetting is connected between the sharp tooth 9 and the threaded barrel 6, the sharp tooth 9 is inserted between the teeth of the ratchet gear 8, and the two cooperate to enable the cutter head 7 to rotate relative to the threaded barrel 6 in only a single direction, so as to prevent the cutter head 7 from rotating in a single direction. Figure 6Taking the perspective of as an example, when the cutter head 7 rotates clockwise, the inclined surface on the teeth of the ratchet gear 8 will squeeze the sharp tooth 9 to slide back into the wall of the threaded tube 6, and the spring is compressed, so the sharp tooth 9 can pass over the teeth of the ratchet gear 8, and then the spring will insert the sharp tooth 9 into the teeth of the ratchet gear 8 again, and the cycle will continue. The sharp tooth 9 is constantly squeezed and moved by the rotating ratchet gear 8, so that the cutter head 7 can rotate clockwise relative to the threaded tube 6. Conversely, the sharp tooth 9 will abut against the plane on the teeth of the ratchet gear 8, and the ratchet gear 8 will no longer be able to control the movement of the sharp tooth 9, so the cutter head 7 cannot rotate counterclockwise relative to the threaded tube 6; rotate the connecting ring 10 installed on the threaded tube 6; fix it at the lower part of the mounting plate 4 and An elastic member a11 between the connecting rings 10, the elastic member a11 is a telescopic spring, and its elastic force is much greater than the weight of the threaded cylinder 6; a limit frame 15 fixedly mounted on the lower part of the mounting plate 4; a moving cylinder 12 slidably mounted on the limit frame 15, the moving cylinder 12 is sleeved on the outside of the threaded cylinder 6 and threadedly mounted on the threaded cylinder 6; a conical cylinder guide sleeve 13 fixedly mounted on the bottom of the moving cylinder 12, a plurality of slits are arranged on the side wall of the conical cylinder guide sleeve 13, and these slits divide the side wall of the conical cylinder guide sleeve 13 into a plurality of independent parts, so that the side wall of the conical cylinder guide sleeve 13 can be deformed when subjected to external force; an inlet 14 for placing a screw 35 is opened on the side wall of the moving cylinder 12.

[0032] Place the coil 33 and the brush base 34 under the assembly unit, so that the assembly unit is against the upper surface of the brush base 34, the elastic member a11 is compressed, and then the servo motor b20 is started to control the rotation of the mounting plate 4. When the cone cylinder guide sleeve 13 moves to the assembly hole of the brush base 34, the elastic member a11 acts to make the cone cylinder guide sleeve 13 pass through the assembly hole of the brush base 34. Then, the mounting plate 4 continues to rotate, and the assembly unit will drive the brush base 34 to rotate until the cone cylinder guide sleeve 13 moves to the assembly hole of the coil 33. Then, the cone cylinder guide sleeve 13 passes through the assembly hole of the coil 33 again, and the servo motor b20 is turned off. At this time, the coil 33 and the brush The assembly space between the base 34 is aligned, so that the device can automatically align the assembly hole between the cone cylinder guide sleeve 13 and the brush base 34 and the coil 33; after the cone cylinder guide sleeve 13 is aligned with the assembly hole between the coil 33 and the brush base 34, the servo motor a5 is started to drive the threaded cylinder 6 to rotate. At this time, in the rotation direction of the threaded cylinder 6, the sharp teeth 9 and the ratchet gear 8 will prevent the cutter head 7 from rotating relative to the threaded cylinder 6, and the cutter head 7 rotates with the threaded cylinder 6. At the same time, the threaded cylinder 6 rotates to control the moving cylinder 12 to move up through the threads thereon, until the moving cylinder 12 is resisted by the servo motor a5 and cannot continue to move up, the threaded cylinder 6 continues to rotate to make the screw The threaded cylinder 6 moves downward relative to the cross axis, and the elastic member a11 is stretched. During the entire relative movement of the threaded cylinder 6 and the moving cylinder 12, the cutter head 7 is first inserted into the cross head of the screw 35, cooperates with the screw 35 and is magnetically connected. Subsequently, the screw 35 is controlled by the cutter head 7 to move downward and rotate relative to the moving cylinder 12. Then, the screw 35 and the cutter head 7 squeeze the cone cylinder guide sleeve 13 to deform and pass through the cone cylinder guide sleeve 13. Finally, the screw 35 passes through the assembly hole between the coil 33 and the brush base 34, and is threadedly engaged with the coil 33, thereby being fixed between the coil 33 and the brush base 34. After completing the assembly of the screw 35, the servo motor a5 controls The threaded barrel 6 is reversed, and in the rotation direction of the threaded barrel 6, the cutter head 7 will be able to rotate relative to the threaded barrel 6. Therefore, after the screw 35 is tightened, the reversed threaded barrel 6 cannot loosen the screw 35 by reversing the screw 35 by the cutter head 7, thereby ensuring the assembly effect of the screw 35; in the process that the cutter head 7 follows the threaded barrel 6 to move up and the moving barrel 12 to move down and reset, the cutter head 7 will be separated from the screw 35, and pass through the conical barrel guide sleeve 13, move into the moving barrel 12 to reset, all components return to the initial state, and the servo motor a5 is turned off; multiple groups of assembly units enable the device to assemble the screw 35 of the coil 33 and the brush base 34 synchronously, thereby improving the assembly efficiency of the device.

[0033] See also Figure 7-Figure 8, and also includes: a guide groove frame 16 fixedly installed on the side wall of the moving cylinder 12, the guide groove frame 16 is located at the position of the inlet 14 on the moving cylinder 12, and the screws 35 can be arranged and placed in the guide groove frame 16; a push plate 17 slidably installed in the guide groove frame 16; an elastic member b18 fixedly installed between the guide groove frame 16 and the push plate 17, and the elastic member b18 is a tension spring; a magnetic plate 19 fixedly installed on the side wall of the moving cylinder 12, and the magnetic plate 19 can adsorb the screws 35.

[0034] The push plate 17 is pulled, the elastic member b18 is stretched, and an appropriate amount of screws 35 are placed in the guide slot frame 16. The push plate 17 is loosened, and the elastic member b18 pushes all the screws 35 to move in the direction of the inlet 14 through the push plate 17. When the innermost screw 35 enters the moving cylinder 12, the screw 35 will be attracted by the magnetic plate 19, and the subsequent screws 35 will be resisted by the screw 35. After the cutter head 7 moves down the screw 35 in the moving cylinder 12, the subsequent screws 35 will be resisted by the threaded cylinder 6 until the threaded cylinder 6 moves up and resets, and the space in the moving cylinder 12 is vacated, and the push plate 17 can push all the screws 35 to move again, add the next screw 35 into the moving cylinder 12, and make the screw 35 be attracted by the magnetic plate 19, and so on. It only needs to replenish the screws 35 in the guide slot frame 16 at a regular interval, so that the device can automatically load the screws 35, thereby improving the convenience of use of the device.

[0036] When the conical guide sleeve 13 passes through the assembly hole on the brush base 34, the conical guide sleeve 13 will be squeezed and deformed. At the same time, its recovery trend caused by the deformation will be stuck with the assembly hole of the brush base 34. Therefore, before assembling the screws 35, the coil 33 and the brush base 34 are loaded on the left and right sides of the assembly table 1. The servo motor c21 controls the rotation of the support arm 3. First, the assembly unit is moved to the top of the brush base 34. The electric telescopic rod 24 controls the assembly unit to move downward so that the assembly unit is stuck in the assembly hole of the brush base 34 to fix the brush base 34. Subsequently, the assembly unit is controlled to move upward and rotate to move the brush base 34 to the top of the coil 33, thereby realizing automatic loading of the brush base 34 on the coil 33 and improving the convenience of use of the device.

The servo motor a5 controls the cutter head 7 to move the screw 35 downward, and tightens the screw 35 between the brush base 34 and the coil 33. After completion, the servo motor a5 controls the cutter head 7 to move up and return to its position, and the screw 35 is automatically replenished; 4. Take out the assembled coil 33, add the next coil 33 to be assembled, that is, repeat the above steps 2-3, and then replenish the screw 35 and the brush base 34 in time.
