Description

Technical Field

[0001] This utility model relates to the technical field of commutator production equipment, specifically a fully automatic commutator press-fitting machine. Background Technology

[0002] The commutator is a key mechanical component in DC motors (including electric motors and generators). Its core function is to change the direction of the current in the rotor windings at the appropriate time, thereby ensuring that the motor can generate continuous torque in a single direction or output DC current with constant polarity. It has been widely used. In the production process of commutators, a commutator press-fitting machine is required to press the commutator onto the rotor shaft at the correct angle and pressure, and ensure that the commutator segments have a precise relative position with the rotor core slots. Its working quality directly affects the performance of the motor.

[0003] In the prior art, such as the fully automatic commutator pressing machine disclosed in CN207431677U, there is a frame, on which are arranged a core feeding mechanism, a core positioning mechanism, a commutator feeding mechanism, a commutator positioning mechanism, and a pressing mechanism. The commutator feeding mechanism includes a storage device, in which a commutator is slidably arranged. The upper end of the storage device is provided with a commutator positioning mechanism, and a lifting device is provided in the commutator positioning mechanism. The lifting device grabs the commutator from the storage device and moves it to the pressing mechanism, etc., realizing fully automated operation. It is only necessary to put the installed commutator into the fixed rod on the base plate, and all subsequent operations can be fully automated.

[0004] The above solution achieves commutator press-fitting in a fully automated manner, saving manpower. In the storage device, the commutator is sleeved onto the fixed rod for temporary storage. When the commutators on multiple fixed rods are used up, new commutators need to be sleeved onto the fixed rod. However, the upper and middle parts of the fixed rod are equipped with various components such as material lifting mechanisms, which can easily cause problems when replenishing commutators, resulting in insufficient operating space and making replenishment more troublesome. Therefore, we provide a fully automatic commutator press-fitting machine to solve the above problems. Utility Model Content

[0017] I. This fully automatic commutator press-fitting machine, by setting up components such as a rotating assembly and a sliding assembly, allows the fixed rod to be rotated outward by the rotating assembly when the commutator on the fixed rod is used up, thus avoiding the influence of other internal components on the fixed rod.

[0026] 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.

[0027] like Figure 1-5As shown, this utility model provides a technical solution: a fully automatic commutator press-fitting machine, including a storage device installed on the press-fitting machine body. The storage device includes: a mounting plate 1 fixed to the press-fitting machine body, a fixed shell 2 fixedly installed on the upper surface of the mounting plate 1, a rotatable rotating plate 3 installed inside the fixed shell 2, a power component 9 installed at the lower part of the rotating plate 3, the power component 9 being used to provide driving force for the rotation of the rotating plate 3; a fixing rod 7 for fixing the commutator, a sliding component 6 installed at the lower end of the fixing rod 7, a support rod 5 installed at the lower part of the sliding component 6, a rotating component 4 installed at the lower end of the support rod 5, and the rotating component 4 being located on the upper surface of the rotating plate 3; the purpose of the sliding component 6 is to increase the lateral movement range of the fixing rod 7, while the rotating component 4 is used to enable the fixing rod 7 to rotate to a position away from the center of the rotating plate 3. The mounting plate 1 is fixedly installed to the press-fitting machine body by bolts. The press-fitting machine body is not shown in the figure, see the prior art cited in the background art. This solution is based on the prior art, mainly The material storage device has been improved, and other aspects will not be elaborated upon. There are multiple fixed rods 7, each with a sliding component 6, a support rod 5, and a rotating component 4. The rotating plate 3 can drive all the fixed rods 7 to rotate. The power component 9 below provides power to cooperate with the internal material lifting device for feeding. A proximity sensor 8 is provided on one side, referring to the prior art, to achieve precise positioning for easy operation. When the commutator on the fixed rod 7 is used up, a new commutator needs to be fitted onto the fixed rod 7. To avoid obstructing the fitting of the commutator, the rotating component 4 can first drive the fixed rod 7 to rotate it to the outside to avoid the influence of other internal components on the fixed rod 7. Then, the sliding component 6 can move the fixed rod 7 laterally to further move it away from the center position, and then the commutator can be fitted onto the fixed rod 7. After that, the fixed rod 7 can be reset and used again, thus avoiding the inconvenience of insufficient space when fitting a new commutator onto the fixed rod 7.

[0028] A support ring 10 is fixedly connected to the inner wall of the fixed shell 2. The outer surface of the support ring 10 is slidably connected to the rotating plate 3. The support ring 10 can support the rotating plate 3 at a position away from the center to increase the stability of the rotating plate 3.

[0029] A bearing 11 is fixedly installed on the lower surface of the rotating plate 3. A bearing seat 12 is rotatably connected to the lower end of the bearing 11. The lower surface of the bearing seat 12 is fixedly connected to the fixed shell 2. The bearing 11 is used to support the center position of the rotating plate 3 in order to increase the stability of the rotating plate 3 and prevent the rotating plate 3 from shifting.

[0030] The power assembly 9 includes a fixed ring 901, the upper surface of which is fixedly connected to the rotating plate 3. A gear ring 902 is fixedly connected to the outer surface of the fixed ring 901. A servo motor 903 is fixedly mounted on the lower surface of the mounting plate 1. The output shaft of the servo motor 903 passes through the mounting plate 1 and the fixed shell 2 and is fixedly connected to a gear 904. The outer surface of the gear 904 meshes with the gear ring 902. The servo motor 903 itself is located below the mounting plate 1 and is set inside the press body. By driving the gear 904 to rotate, it can indirectly drive the rotation of the rotating plate 3. A limit ring 13 is also fixedly connected to the bottom of the fixed rod 7 to limit the upper steering mechanism.

[0031] The rotating assembly 4 includes a fixed base 401, the lower surface of which is fixedly connected to the rotating plate 3. A rotating block 402 is rotatably connected to the inner wall of the fixed base 401. The upper surface of the rotating block 402 is fixedly connected to the support rod 5. A fixed cylinder 403 is fixedly connected to the outer surface of the fixed base 401. A through groove 404 is provided on the inner wall of the rotating block 402. An insert rod 405 is slidably connected to the outer surface of the fixed cylinder 403. The end of the insert rod 405 is slidably connected to the through groove 404. By inserting the insert rod 405 into the through groove 404, the rotating block 402 can be fixed. When rotating, the insert rod 405 can be pulled out, the support rod 5 can be rotated 180 degrees, and then the insert rod 405 can be inserted into the other end to be fixed again, so as to facilitate external operation.

[0032] A circular block 406 is slidably connected to the inner wall of the fixed cylinder 403. The outer surface of the circular block 406 is slidably connected to the fixed cylinder 403. A first spring 407 is fixedly connected to one side of the circular block 406. The end of the first spring 407 is fixedly connected to the fixed cylinder 403. A pull ring 408 is fixedly connected to the end of the insertion rod 405. The first spring 407 gives the circular block 406 a spring force close to the fixed seat 401 so that the insertion rod 405 can be automatically inserted into the through groove 404.

[0033] The sliding assembly 6 includes a hollow cylinder 601. The lower surface of the hollow cylinder 601 is fixedly connected to the support rod 5. The inner wall of the hollow cylinder 601 is slidably connected to the lower part of the fixed rod 7. A second spring 602 is fixedly connected inside the hollow cylinder 601. The end of the second spring 602 is fixedly connected to the fixed rod 7. A locking member 603 is slidably connected to the inner wall of the hollow cylinder 601. The outer surface of the locking member 603 is also threadedly connected to the fixed rod 7. The hollow cylinder 601 and the fixed rod 7 are fixed by the locking member 603. When sliding is required, the locking member 603 is unscrewed. Under the action of the second spring 602, the fixed rod 7 is ejected outward so that the fixed rod 7 can move laterally. At the same time, both ends of the second spring 602 are fixedly connected to prevent the fixed rod 7 from sliding out completely.

[0034] Working principle: The fixed shell 2 serves as the cavity for accommodating components. The support ring 10 on its inner wall cooperates with the bearing seat 12 and bearing 11 at the bottom to provide double support for the edge and center of the rotating plate 3, ensuring the stability of the rotating plate 3 during rotation and preventing deviation.

[0035] The rotating plate 3 is the core carrier that supports all the fixed rods 7. The power assembly 9 provides driving force for its rotation. In the power assembly 9, the servo motor 903 can drive the rotating plate 3 and all the fixed rods 7 above it to rotate synchronously. Together with the proximity sensing device 8 inside the press machine, it can achieve precise positioning of the fixed rods 7 and meet the material picking requirements of the lifting device.

[0036] During normal operation of the press machine, the power unit 9 drives the entire rotating plate 3 to rotate within the fixed housing 2. The rotating plate 3 drives all the fixed rods 7 above to rotate synchronously. When a fixed rod 7 rotates to the material picking position corresponding to the lifting device, the proximity sensing device 8 of the press machine body, referring to the prior art, detects the position signal of the fixed rod 7 and immediately feeds it back to the control system. The control system issues a stop command, the servo motor 903 stops running, and the rotating plate 3 and the fixed rod 7 precisely stop at the material picking position, ensuring that the lifting device can accurately grab the commutator on the fixed rod 7.

[0037] After the commutator on a certain fixed rod 7 is removed, the operator first operates the rotating component 4 corresponding to the empty fixed rod 7, pulling the insertion rod 405 outward. The insertion rod 405 disengages from the through groove 404 of the rotating block 402, releasing the fixing of the rotating block 402. At this time, the rotating block 402 can rotate freely on the inner wall of the fixed base 401. The operator pushes the support rod 5 upward, causing the rotating block 402 to rotate 180° around the axis of the fixed base 401, so that the fixed rod 7 originally facing the center of the rotating plate 3 rotates to an outer position away from the center, avoiding the material lifting device, other fixed rods 7 and other components inside the fixed shell 2, and initially expanding the operating space.

[0038] After the fixed rod 7 is rotated outward, the operator unscrews the locking part 603 in the sliding assembly 6. Since the locking part 603 is simultaneously slidably connected to the inner wall of the hollow cylinder 601 and threadedly connected to the lower part of the fixed rod 7, the fixed relationship between the hollow cylinder 601 and the fixed rod 7 is released after the locking part 603 is unscrewed. At this time, the second spring 602 inside the hollow cylinder 601 releases its elastic potential energy, pushing the fixed rod 7 to extend laterally along the inner wall of the hollow cylinder 601 away from the center of the rotating plate 3, further increasing the distance between the fixed rod 7 and the internal components, providing sufficient operating space for inserting the commutator.

[0039] The operator inserts the new commutator along the fixed rod 7 from top to bottom to complete the replenishment. Then, the fixed rod 7 is pushed towards the hollow cylinder 601 to compress the second spring 602, causing the fixed rod 7 to retract to its initial position. The locking piece 603 is then screwed back into its original position to complete the reset of the sliding assembly 6. Finally, the support rod 5 is pushed in the opposite direction to rotate the rotating block 402 180° back to its initial position. At this time, the insertion rod 405 is released, and the first spring 407 in the fixed cylinder 403 releases its elastic force, pushing the round block 406 towards the fixed seat 401. This causes the insertion rod 405 to automatically insert into the through slot 404 of the rotating block 402, re-fixing the rotating block 402 and completing the reset of the rotating assembly 4.
