Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically to an auxiliary device for assembling a hook-type commutator. Background Technology

[0002] The hook commutator is a core component of a micro motor, consisting of an insulating substrate and circumferentially distributed arc-shaped copper hooks. Traditional assembly relies on manual alignment, and the arc-shaped copper hooks need to be precisely arranged in the grooves of the substrate. However, manual operation is prone to deviation, making it difficult to position the copper hooks. Furthermore, manual pressing can result in uneven pressure, which can easily lead to substrate cracking or copper hook deformation. To address these issues, the inventors have proposed an auxiliary device for assembling hook commutators. Utility Model Content

[0003] To address the problems of difficult copper hook positioning and uneven pressure during the assembly of current hook-type commutators, the purpose of this invention is to provide an auxiliary device for assembling hook-type commutators.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an auxiliary device for assembling a hook-type commutator, comprising a base, a rotating platform rotatably connected to the top surface of the base, a base positioning column fixedly connected to the center of the top surface of the rotating platform, a guide groove provided on the side wall of the base positioning column, a magnetic seat embedded in the top surface of the rotating platform and on one side of the base positioning column, a vertical cylinder provided on one side of the rotating platform, the vertical cylinder being placed vertically, a lifting column being inserted through the opening of the vertical cylinder and being able to be raised and lowered, a slot provided on the side wall of the lifting column, a horizontal plate fixedly connected to the top of the lifting column, an electric cylinder provided at the end of the horizontal plate, a pressure plate fixedly connected to the output shaft end of the electric cylinder, the pressure plate being located above the base positioning column and corresponding to the guide groove.

[0005] Preferably, the top surface of the base is provided with an annular groove, and the bottom surface of the rotating platform is fixedly connected with a guide ring. The guide ring corresponds to and is rotatably connected to the annular groove. When the rotating platform rotates, the cooperation between the guide ring and the annular groove makes the rotation of the rotating platform more stable. When assisting in the assembly of the hook-type commutator, the commutator base can be fitted onto the base positioning post, so that the groove of the commutator base corresponds to the guide groove, and it is fixed by the magnetic seat on the rotating platform. Then, the copper hook is slid in along the guide groove, and the electric cylinder is activated to press down the pressure plate. The pressure plate is a silicone pressure head, so that the copper hook is embedded into the groove of the commutator base along the guide groove, thereby completing the auxiliary assembly. To assist in assembly, a motor is installed inside the base, and a worm gear is fixedly connected to the output shaft of the motor. A rotating shaft is fixedly connected to the center of the bottom surface of the rotating table, and the bottom end of the rotating shaft is rotatably connected to the base. A worm wheel is fixedly sleeved on the side wall of the rotating shaft, and the worm wheel corresponds to and meshes with the worm. A base is provided on the side wall of the motor, and the base is fixedly connected to the inner wall of the base. The motor is installed through the base. When the motor is started, the worm gear rotates under the action of the motor output shaft. Through the meshing of the worm gear and the worm wheel, the rotating shaft can be rotated, which in turn causes the rotating table to drive the commutator base to rotate, so as to cooperate with the pressure plate for continuous copper hook pressing operation.

[0006] Preferably, a boss is fixedly connected to the bottom surface of the vertical cylinder, and the side wall of the boss is fixedly connected to the outer side wall of the base. The vertical cylinder is installed and fixed through the boss. A threaded hole is provided through the upper part of the side wall of the vertical cylinder. A fastening knob is provided on one side of the vertical cylinder. The fastening knob cooperates with the threaded hole, and the rod end of the fastening knob cooperates with the slot. Loosening the fastening knob separates the rod end of the fastening knob from the slot, thereby adjusting the position of the lifting column up and down. This allows for quick adjustment of the height of the electric cylinder to accommodate bases of different thicknesses. After adjustment, the lifting column needs to be finely adjusted again so that the rod end of the fastening knob corresponds to the adjacent slot on the lifting column. Tightening the fastening knob in the opposite direction inserts the rod end of the fastening knob into the slot, thus completing the limiting and fixing of the lifting column. A fixing seat is provided on the side wall of the electric cylinder, and the side wall of the fixing seat is fixedly connected to the side wall of the horizontal plate. The electric cylinder is installed and fixed through the fixing seat.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: the magnetic base can fix the commutator base to improve stability; the base positioning post and guide groove facilitate auxiliary positioning of the copper hook; the silicone pressure head can make the pressing force uniform, avoiding manual pressing that could cause the base to crack or the copper hook to deform; and the rotating table can drive the commutator base to rotate to cooperate with the pressure plate for continuous copper hook pressing operation, thus providing better auxiliary use for the assembly of hook commutators.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example: Figure 1-3 As shown, this utility model provides an auxiliary device for assembling a hook-type commutator, including a base 1, a rotating platform 3 rotatably connected to the top surface of the base 1, a base positioning column 5 fixedly connected to the center of the top surface of the rotating platform 3, a guide groove 6 provided on the side wall of the base positioning column 5, a magnetic seat 4 embedded in the top surface of the rotating platform 3 and on one side of the base positioning column 5, a vertical cylinder 8 provided on one side of the rotating platform 3, the vertical cylinder 8 is placed vertically, a lifting column 11 is inserted through the opening of the vertical cylinder 8 and can be raised and lowered, a slot 12 is provided on the side wall of the lifting column 11, a horizontal plate 13 is fixedly connected to the top of the lifting column 11, an electric cylinder 15 is provided at the end of the horizontal plate 13, a pressure plate 16 is fixedly connected to the output shaft end of the electric cylinder 15, the pressure plate 16 is located above the base positioning column 5 and corresponds to the guide groove 6.

[0015] The top surface of the base 1 is provided with an annular groove 2, and the bottom surface of the rotating platform 3 is fixedly connected with a guide ring, which corresponds to and is rotatably connected to the annular groove 2.

[0016] By adopting the above technical solution, when the rotating table 3 rotates, the mutual cooperation between the guide ring and the annular groove 2 makes the rotation of the rotating table 3 more stable. When assisting in the assembly of the hook-type commutator, the commutator base 22 can be fitted onto the base positioning post 5, and the groove of the commutator base 22 can be aligned with the guide groove 6. It can be fixed by the magnetic seat 4 on the rotating table 3. Then, the copper hook 23 is slid in along the guide groove 6, and the electric cylinder 15 is activated to make the pressure plate 16 press down. The pressure plate 16 is a silicone pressure head, so that the copper hook 23 is embedded in the groove of the commutator base 22 along the guide groove 6, thereby completing the auxiliary assembly operation.

[0017] A motor 17 is installed inside the base 1. A worm gear 19 is fixedly connected to the output shaft end of the motor 17. A rotating shaft 21 is fixedly connected to the middle of the bottom surface of the rotating table 3. The bottom end of the rotating shaft 21 is rotatably connected to the base 1. A worm wheel 20 is fixedly sleeved on the side wall of the rotating shaft 21. The worm wheel 20 corresponds to and meshes with the worm gear 19. A base 18 is provided on the side wall of the motor 17. The base 18 is fixedly connected to the inner wall of the base 1.

[0018] By adopting the above technical solution, the motor 17 is installed on the base 18. When the motor 17 is started, the worm 19 rotates under the action of the output shaft of the motor 17. Through the meshing of the worm 19 and the worm wheel 20, the rotating shaft 21 can be rotated, which in turn causes the rotating table 3 to drive the commutator base 22 to rotate, so as to cooperate with the pressure plate 16 to perform continuous copper hook 23 pressing operation.

[0019] The bottom surface of the vertical cylinder 8 is fixedly connected to a boss 7, and the side wall of the boss 7 is fixedly connected to the outer side wall of the base 1.

[0020] By adopting the above technical solution, the vertical cylinder 8 is installed and fixed by the boss 7.

[0021] A threaded hole 9 is provided through the upper part of the side wall of the vertical cylinder 8. A fastening knob 10 is provided on one side of the vertical cylinder 8. The fastening knob 10 is engaged with the threaded hole 9, and the rod end of the fastening knob 10 is engaged with the slot 12.

[0022] By adopting the above technical solution, loosening the fastening knob 10 separates the rod end of the fastening knob 10 from the slot 12, allowing the position of the lifting column 11 to be adjusted up and down. This enables the rapid adjustment of the height of the electric cylinder 15 to accommodate substrates of different thicknesses. After adjustment, the lifting column 11 needs to be finely adjusted again so that the rod end of the fastening knob 10 corresponds to the slot 12 on the lifting column 11. By turning the fastening knob 10 in the opposite direction, the rod end of the fastening knob 10 is inserted into the slot 12, thus completing the limiting and fixing of the lifting column 11.

[0023] The electric cylinder 15 has a fixed seat 14 on its side wall, and the side wall of the fixed seat 14 is fixedly connected to the side wall of the cross plate 13.

[0024] By adopting the above technical solution, the electric cylinder 15 is installed and fixed by the fixed seat 14, the commutator base 22 can be sleeved on the base positioning post 5 and fixed by the magnetic seat 4 on the rotating table 3. After the auxiliary assembly is completed, the commutator base 22 can be pulled upward to remove the commutator base 22 from the base positioning post 5. During the auxiliary assembly, the copper hook 23 can cooperate with the guide groove 6. The guide groove 6 is used to guide the copper hook 23 to avoid deformation of the copper hook 23 during pressing.

[0025] Working principle: When using this utility model to assist in the assembly of the hook-type commutator, the commutator base 22 can be fitted onto the base positioning post 5, so that the groove of the commutator base 22 corresponds to the guide groove 6, and it is fixed by the magnetic seat 4 on the rotating table 3. Then, the copper hook 23 is slid in along the guide groove 6, and the electric cylinder 15 is activated so that the pressure plate 16 is pressed down, so that the copper hook 23 is embedded in the groove of the commutator base 22 along the guide groove 6, thereby completing the auxiliary assembly operation.

[0026] Next, the motor 17 can be started, and the worm gear 19 rotates under the action of the output shaft of the motor 17. Through the meshing of the worm gear 19 and the worm wheel 20, the rotating shaft 21 can be rotated, which in turn causes the rotating table 3 to drive the commutator base 22 to rotate, so that the groove that has not been pressed into the copper hook 23 moves to the pressure plate 16, thereby cooperating with the pressure plate 16 to perform continuous copper hook 23 pressing operation.

[0027] When adjusting the height of the horizontal plate 13, loosen the fastening knob 10 so that the rod end of the fastening knob 10 is separated from the slot 12. This allows the position of the lifting column 11 to be adjusted up and down, and the height of the electric cylinder 15 to be quickly adjusted to accommodate substrates of different thicknesses. After the adjustment is completed, the lifting column 11 is finely adjusted again so that the rod end of the fastening knob 10 corresponds to the slot 12 on the lifting column 11. Then, the fastening knob 10 is turned in the opposite direction so that the rod end of the fastening knob 10 is inserted into the slot 12, thus completing the limiting and fixing of the lifting column 11.

[0028] After assembly is completed, control the electric cylinder 15 to raise the pressure plate 16 to prevent the pressure plate 16 from affecting the use of the assembled commutator base 22. Then, lift the assembled base upwards to remove the base from the base positioning post 5 for use.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
