Description

Technical Field

[0001] This utility model relates to the field of copper busbar bending machine technology, specifically a DC motor rotor coil winding bending device. Background Technology

[0002] Some DC motors have rotor coil windings composed of several copper busbars connected together. These copper busbars are generally installed in slots on the motor rotor, and the ends of these copper busbars need to be bent according to the layout requirements.

[0003] The bending of existing DC motor rotor coil windings is generally performed using a copper busbar bending machine. A copper busbar bending machine is a specialized piece of equipment for processing copper busbars (rectangular cross-section conductive metal strips). Its main structural components include: a power system: providing the power required for bending and driving the actuator to complete the bending action; an actuator: converting the energy of the power system into bending action, directly acting on the copper busbar; a die system: determining the bending angle, radius, and shape of the copper busbar, directly affecting the processing quality; a clamping device: fixing the copper busbar, preventing displacement during bending, and ensuring accurate bending position; and a control system: controlling parameters such as bending angle, stroke, and speed to achieve automated operation.

[0004] When bending the rotor coil winding of a DC motor using a copper busbar bending machine, there is a certain distance between the rotating mandrel on the main body of the bending machine and the bending die. As the length of the copper busbar conveyed by the rotating mandrel increases, the copper busbar is prone to vibration, which affects the bending operation. Based on this, a DC motor rotor coil winding bending device is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a device for bending the rotor coil winding of a DC motor in order to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a DC motor rotor coil winding bending device, comprising a copper busbar bending machine consisting of a bending machine body, a mold system, and a rotating mandrel. The mold system is mounted on the front end of the bending machine body via a slide table. The rotating mandrel is rotatably mounted inside the bending machine body and extends through the front end of the bending machine body to the area above the mold system. The front end of the bending machine body is provided with an anti-vibration component extending to the front end of the rotating mandrel. The anti-vibration component is used to limit and guide the copper busbar conveyed from the rotating mandrel.

[0007] The image stabilization component includes a de-shake unit and a drive unit;

[0008] The driving unit is used to drive the anti-shake unit to move horizontally back and forth, and the anti-shake unit moves forward to eliminate the shaking of the copper busbar.

[0009] As a further embodiment of this utility model: the shake-removal unit includes a T-shaped ring, an L-shaped connecting arm, and a reinforcing sleeve;

[0010] The T-shaped ring sleeve is fitted onto the outside of the rotating mandrel. One end of the L-shaped connecting arm is fixedly connected to the T-shaped ring sleeve, and the end of the L-shaped connecting arm away from the T-shaped ring sleeve extends to the front end of the rotating mandrel and is fixedly connected to the reinforcing sleeve.

[0011] The reinforcing sleeve is aligned with the discharge port of the rotating mandrel, and the inner wall shape of the reinforcing sleeve matches the outer wall of the copper busbar. The copper busbar conveyed from the rotating mandrel passes through the reinforcing sleeve, and the reinforcing sleeve moves forward to limit the shaking of the copper busbar, thereby eliminating the shaking of the copper busbar between the front end of the rotating mandrel and the mold system.

[0012] As a further embodiment of this utility model: the drive unit includes an L-shaped fixed frame, a reducer, a lead screw, a screw sleeve, and an arc-shaped guide rail;

[0013] The L-shaped fixing frame is fixed to the front end of the bending machine body and distributed above the rotating mandrel. The reducer is fixed to the bottom of the horizontal part of the L-shaped fixing frame. The output end of the reducer is connected to the lead screw, and the other end of the lead screw is rotatably connected to the vertical part of the L-shaped fixing frame.

[0014] The screw sleeve is threaded to the outside of the lead screw, the arc-shaped guide rail is fixed to the bottom of the screw sleeve, and the T-shaped ring is rotatably connected to the inside of the arc-shaped guide rail;

[0015] The screw is driven to rotate by a speed reducer to achieve the overall horizontal movement of the screw sleeve, arc guide rail, and de-vibration unit.

[0016] As a further embodiment of this utility model: a limiting guide groove is provided on the outer side of the rotating mandrel, and a guide rod is fixed on the outer wall of the transverse part of the L-shaped connecting arm, and the guide rod is slidably connected to the limiting guide groove.

[0017] As a further improvement of this utility model: multiple L-shaped connecting arms are provided, and the multiple L-shaped connecting arms are evenly distributed in a ring around the rotating spindle. The number of limiting guide grooves and guide rods matches the number of L-shaped connecting arms.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] By setting up anti-vibration components, when the copper busbar vibrates, the reducer drives the lead screw to rotate. The rotation of the lead screw drives the screw sleeve, arc guide rail, T-shaped annular groove, L-shaped connecting arm, and reinforcing sleeve to move forward as a whole. As the reinforcing sleeve approaches the mold system, it can limit the vibration of the copper busbar 3, thereby simulating the manual operation of supporting the copper busbar to eliminate vibration, so that the vibration of the copper busbar in the middle area between the front end of the rotating mandrel and the mold system is eliminated.

[0024] 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.

[0025] Please see Figures 1-3 In this embodiment of the present invention, a DC motor rotor coil winding bending device includes a copper busbar bending machine 1 consisting of a bending machine body 101, a mold system 102, and a rotating mandrel 103. The mold system 102 is mounted on the front end of the bending machine body 101 via a slide table. The rotating mandrel 103 is rotatably mounted inside the bending machine body 101 and extends through the front end of the bending machine body 101 to the area above the mold system 102. The front end of the bending machine body 101 is provided with an anti-shake component 2 extending to the front end of the rotating mandrel 103. The anti-shake component 2 is used to limit and guide the copper busbar 3 conveyed from the rotating mandrel 103.

[0026] The anti-shake component 2 includes a de-shake unit and a drive unit. The drive unit is used to drive the anti-shake unit to move horizontally back and forth, and the de-shake unit moves forward to eliminate the shaking of the copper busbar 3.

[0027] The shake-removal unit includes a T-shaped ring 206, an L-shaped connecting arm 207, and a reinforcing sleeve 208;

[0028] T-shaped sleeve 206 is sleeved on the outside of rotating mandrel 103. One end of L-shaped connecting arm 207 is fixedly connected to T-shaped sleeve 206. The end of L-shaped connecting arm 207 away from T-shaped sleeve 206 extends to the front end of rotating mandrel 103 and is fixedly connected to reinforcing sleeve 208.

[0029] The reinforcing sleeve 208 is aligned with the discharge port of the rotating mandrel 103, and the inner wall shape of the reinforcing sleeve 208 matches the outer wall of the copper busbar. The copper busbar 3 conveyed from the rotating mandrel 103 passes through the reinforcing sleeve 208. The reinforcing sleeve 208 moves forward to limit the shaking copper busbar 3, thereby eliminating the shaking of the copper busbar 3 between the front end of the rotating mandrel 103 and the mold system 102.

[0030] The drive unit includes an L-shaped fixed frame 201, a reducer 202, a lead screw 203, a screw sleeve 204, and an arc-shaped guide rail 205;

[0031] The L-shaped fixing frame 201 is fixed to the front end of the bending machine body 101 and distributed above the rotating mandrel 103. The reducer 202 is fixed to the bottom of the horizontal part of the L-shaped fixing frame 201. The output end of the reducer 202 is connected to the lead screw 203, and the other end of the lead screw 203 is rotatably connected to the vertical part of the L-shaped fixing frame 201.

[0032] The screw sleeve 204 is threaded to the outside of the lead screw 203, the arc-shaped guide rail 205 is fixed to the bottom of the screw sleeve 204, and the T-shaped ring sleeve 206 is rotatably connected to the inside of the arc-shaped guide rail 205.

[0033] The reducer 202 drives the lead screw 203 to rotate, thereby enabling the overall horizontal movement of the screw sleeve 204, the arc-shaped guide rail 205, and the de-vibration unit.

[0034] In this embodiment, it should be noted that the copper busbar bending machine 1 is a CX-9 copper-aluminum hard busbar bending machine. The main body 101 of the bending machine is used for conveying and rotating the copper busbar 3, and the mold system 102 is used for bending the copper busbar 3 at different angles and cutting operations. This function is an existing function of the CX-9 copper-aluminum hard busbar bending machine, so it will not be described in detail.

[0035] When performing copper busbar bending operations, if the length of the copper busbar extending beyond the rotating mandrel 103 is relatively long, the copper busbar will vibrate after each bending operation. This vibration can be eliminated by using an anti-vibration component, the operating principle of which is as follows:

[0036] The drive motor of the reducer 202 is started, causing the lead screw 203 to rotate. The rotation of the lead screw 203 drives the screw sleeve 204, the arc-shaped guide rail 205, the T-shaped annular groove 206, the L-shaped connecting arm 207, and the reinforcing sleeve 208 to move forward as a whole. As the reinforcing sleeve 208 approaches the mold system 102, it can limit the shaking of the copper busbar 3, thereby simulating the manual operation of supporting the copper busbar 3 to eliminate the shaking. This eliminates the shaking of the copper busbar 3 in the middle area between the front end of the rotating mandrel 103 and the mold system 102. After that, the drive motor of the reducer 202 runs in reverse, causing the reinforcing sleeve 208 to return to its initial position (i.e., close to the front end of the rotating mandrel 103). Then, the secondary bending operation can be performed. Its anti-shake component 2 will not affect the operation of the mold system 102.

[0037] Please refer to this carefully. Figures 1-3 A limiting guide groove 104 is provided on the outer side of the rotating spindle 103, and a guide rod 209 is fixed on the outer wall of the transverse part of the L-shaped connecting arm 207. The guide rod 209 is slidably connected to the limiting guide groove 104.

[0038] Multiple L-shaped connecting arms 207 are provided, and the multiple L-shaped connecting arms 207 are evenly distributed in a ring around the rotating spindle 103. The number of limiting guide grooves 104 and guide rods 209 are matched with the number of L-shaped connecting arms 207.

[0039] In this embodiment: through the cooperation of the limiting guide groove 104 and the guide rod 209, the T-shaped annular groove 206, the L-shaped connecting arm 207, and the reinforcing sleeve 208 can rotate synchronously with the rotating spindle 103. Thus, when the rotating spindle 103 rotates to rotate the copper busbar 3, the reinforcing sleeve 208 rotates synchronously with the copper busbar 3, and will not cause twisting to the copper busbar 3.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
