Description

Technical Field

[0001] This utility model relates to the field of rotor welding technology, specifically to a continuous welding device for motor rotors.

[0002] The motor rotor is one of the core components of a motor, mainly composed of a rotor core, rotor windings (or permanent magnets), and a shaft. In a rotating motor, the rotor is mounted inside the stator via bearings and rotates under the action of electromagnetic force, converting electrical energy into mechanical energy to drive the mechanical equipment. For example, in a washing machine motor, the high-speed rotation of the rotor drives the drum to rotate, achieving the washing function. Its performance directly affects key indicators such as motor efficiency, power density, and speed range. The main purposes of motor rotor welding include: first, connecting the various rotor components, firmly welding the rotor core to the shaft to ensure the stability of the overall rotor structure, enabling it to withstand the centrifugal force generated by high-speed rotation; second, optimizing rotor performance, as the welding process allows for precise control of the rotor winding connection method, reducing resistance, minimizing energy loss, and improving motor efficiency; and third, enhancing heat dissipation, as a reasonable welding structure facilitates heat conduction, preventing rotor damage due to overheating and extending the motor's service life.

[0003] A search revealed that CN212496146U discloses an automatic continuous welding device, including a conveyor frame, a support rod, a welding torch, and an air pump. Mounting seats are provided on both the front and rear sides of the conveyor frame. A limiting plate is connected to the output end of the hydraulic rod. The support rod is welded to the upper surface of the conveyor frame. A servo motor is mounted on the rear side of the crossbeam. An adjusting plate is threaded to the outer side of the lead screw, and an electric telescopic rod is installed inside the adjusting plate. Side plates are welded to both ends of the lower surface of the adjusting plate, and mounting plates are installed on the inner sides of the side plates. The welding torch is mounted on the lower surface of the mounting plate, and the air pump is mounted on the upper surface of the crossbeam, with a processing box connected to its input end. This automatic continuous welding device avoids misalignment of metal pipes and sheets during continuous welding and conveying, facilitates adjustment of the welding torch's tilt angle according to welding needs, and handles most toxic gases, reducing the harm of toxic gases to workers.

[0004] The aforementioned automatic continuous welding device can only move along a fixed track and cannot achieve continuous circular welding. It requires multiple manual interventions to adjust the welding angle, resulting in low efficiency. Utility Model Content

[0005] This invention proposes a continuous welding device for motor rotors, which solves the problem of low welding efficiency caused by the need for frequent manual intervention to adjust the welding angle when adjusting the welding point in the existing technology.

[0006] The technical solution of this utility model is as follows: A continuous welding device for motor rotors includes a support assembly, the support assembly including a support base and a support platform, the support platform being fixedly connected to the top of the support base, a track groove being provided at the bottom of the support base, and a clamping assembly capable of quickly clamping or releasing the rotor to be welded being provided at the track groove and the support platform, and an annular groove being provided through the middle of the support base and the support platform, and a self-rotating welding assembly capable of freely rotating in an annular shape and completing continuous welding of the rotor being provided at the annular groove.

[0007] Preferably, the clamping assembly includes a first forward and reverse motor, which is fixedly installed in the rail groove. The clamping assembly also includes a bidirectional screw, which is fixedly connected to the output end of the first forward and reverse motor. The bidirectional screw is rotatably connected to the rail groove through the first forward and reverse motor.

[0008] Preferably, the clamping assembly further includes two sets of slides, which are threadedly connected to opposite threads on both sides of the bidirectional screw. The clamping assembly also includes a main connecting rod, and each main connecting rod is fixedly connected to each slide.

[0009] Preferably, the clamping assembly further includes a support rod, which is symmetrically fixedly connected to both sides of the end of the main connecting rod. The clamping assembly also includes a V-groove clamping block, which is fixedly connected to the end of the support rod away from the main connecting rod.

[0010] Preferably, the self-rotating welding assembly includes a ring seat, which is fixedly connected to the ring groove. The self-rotating welding assembly also includes a second forward and reverse motor, which is fixedly installed on the outside of the ring seat, and a geared disc is fixedly connected to the output end of the second forward and reverse motor.

[0011] Preferably, the self-rotating welding assembly further includes a ring sleeve, which is disposed inside the ring seat, and the outer side of the ring sleeve is rotatably connected to the ball bearings. The ring sleeve is rotatably connected to the inner side of the ring seat through the ball bearings.

[0012] Preferably, the self-rotating welding assembly further includes a toothed groove group, which is distributed on the outside of the ring sleeve and is in contact with the toothed disc and is meshed and rotatably connected.

[0013] Preferably, the self-rotating welding assembly further includes a side seat, which is fixedly connected to the side of the ring sleeve; the self-rotating welding assembly further includes a cylinder, which is fixedly installed in the middle of the side seat; and the self-rotating welding assembly further includes a welding mechanism, which is fixedly installed at the output end of the cylinder.

[0014] The beneficial effects of this utility model are as follows:

[0015] I. Rotor-specific adaptive clamping design

[0016] This patent employs a V-groove clamping block + bidirectional screw linkage structure. A first forward and reverse motor drives the bidirectional screw, causing the V-groove clamping blocks to move synchronously in opposite directions, perfectly adapting to the cylindrical structure of the motor rotor. In contrast, the prior art only uses a hydraulic rod to constrain the metal tube, lacking specific radial positioning of the rotor, which can easily lead to unstable clamping or damage to the rotor surface.

[0017] II. 360-degree full-circle dynamic welding path

[0018] Through the toothed disc-tooth groove meshing transmission and the ring sleeve rotation structure, the welding mechanism can rotate continuously around the rotor axis, achieving welding without dead angles. The welding torch in the comparison document can only move linearly or make minor angle adjustments, requiring multiple stops to adjust the welding position, which cannot meet the continuity requirements of rotor welding.

[0026] Please see Figure 1 and Figure 2 and Figure 3 and Figure 4 The present invention provides a technical solution: a continuous welding device for motor rotor, including a support component 1, the support component 1 including a support base 11 and a support platform 14, the support platform 14 being fixedly connected to the top of the support base 11, a rail groove 12 being provided at the bottom of the support base 11, a clamping component 2 being provided at the rail groove 12 and the support platform 14 for quickly clamping or releasing the rotor to be welded, an annular groove 13 being provided through the middle of the support base 11 and the support platform 14, a self-rotating welding component 3 being provided at the annular groove 13 for freely rotating in an annular shape and completing continuous welding of the rotor;

[0027] This design solves the problems of low positioning accuracy and discontinuous welding in rotor processing by traditional welding devices through two core innovations: adaptive clamping structure and dynamic welding path, which significantly improves production efficiency and process quality.

[0028] Please see Figure 1 Figure 2 and Figure 3 The clamping assembly 2 includes a first forward and reverse motor 21, which is fixedly installed in the rail groove 12. The clamping assembly 2 also includes a bidirectional screw 211, which is fixedly connected to the output end of the first forward and reverse motor 21. The bidirectional screw 211 is rotatably connected to the rail groove 12 through the first forward and reverse motor 21.

[0029] The clamping assembly 2 also includes two sets of slides 22, which are threadedly connected to opposite threads on both sides of the bidirectional screw 211. The clamping assembly 2 also includes a main connecting rod 221, which is fixedly connected to each slide 22.

[0030] The clamping assembly 2 also includes a support rod 23, which is symmetrically fixedly connected to both sides of the end of the main connecting rod 221. The clamping assembly 2 also includes a V-groove clamping block 231, which is fixedly connected to the end of the support rod 23 away from the main connecting rod 221.

[0031] This design enables rapid positioning of the rotor before welding and rapid release after welding.

[0032] Please see Figure 1 Figure 2 and Figure 4 The self-rotating welding assembly 3 includes a ring seat 36, which is fixedly connected to the ring groove 13. The self-rotating welding assembly 3 also includes a second forward and reverse motor 31, which is fixedly installed on the outside of the ring seat 36. A toothed disk 311 is fixedly connected to the output end of the second forward and reverse motor 31.

[0033] The self-rotating welding assembly 3 also includes a ring sleeve 32, which is located inside the ring seat 36. The outer side of the ring sleeve 32 is rotatably connected to the ball bearing 322 in a ring shape. The ring sleeve 32 is rotatably connected to the inner side of the ring seat 36 through the ball bearing 322.

[0034] The self-rotating welding assembly 3 also includes a toothed groove group 321, which is distributed on the outside of the ring 32. The toothed groove group 321 is in contact with the toothed disk 311 and is meshing and rotatingly connected.

[0035] The self-rotating welding assembly 3 also includes a side seat 33, which is fixedly connected to the side of the ring 32. The self-rotating welding assembly 3 also includes a cylinder 34, which is fixedly installed in the middle of the side seat 33.

[0036] This design allows the welding mechanism 35 to rotate continuously in a ring around the rotor to the target welding point, thereby achieving rapid welding of the rotor.

[0037] Working principle:

[0038] First, place the rotor to be welded in the middle of the support platform 14, and keep the two sides of the rotor aligned with the positions of the V-groove clamping blocks 231;

[0039] Then, the first forward and reverse motor 21 is started to drive the bidirectional screw 211 to rotate, which in turn causes the slide block 22, which is threaded to the opposite threads on both sides of the bidirectional screw 211, to drive the main connecting rod 221 to move synchronously in opposite directions. At this time, the support connecting rod 23 fixed on both sides of each main connecting rod 221 can drive the V-groove clamping block 231 to move synchronously in opposite directions and complete the positioning of the rotor. Similarly, when the rotor welding process is completed, the first forward and reverse motor 21 is started to drive the bidirectional screw 211 to reverse, which completes the release and release of the V-groove clamping block 231 on the rotor.

[0040] When welding is required on the rotor, the second forward and reverse motor 31 can be started to drive the gear disk 311 to rotate. Under the meshing and rotation of the gear disk 311 and the tooth groove group 321, the ring sleeve 32 will drive the side seat 33 to rotate synchronously horizontally. When the rotation is such that the welding mechanism 35 corresponds to the position of the rotor to be welded, the cylinder 34 is started so that the extension end of the cylinder 34 drives the welding mechanism 35 to be horizontally advanced until the welding mechanism 35 contacts the rotor, and the subsequent welding work can be completed.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
