Description

Technical Field

[0001] This application belongs to the field of motor assembly, and more specifically, relates to a steel sleeve welding machine. Background Technology

[0002] An electric motor mainly consists of a rotor and a stator. When conductive wires are wound on the stator, magnets are installed on the rotor. In the rotor assembly process, after the rotor core is fitted with magnets, the rotor needs to be installed into a steel sleeve, and then the shaft is installed. Finally, the steel sleeve and the shaft are welded together to complete the rotor assembly.

[0003] However, existing steel sleeve welding machines can only weld one end of the shaft and the steel sleeve. The rotor assembly needs to be manually rotated to weld the other end of the shaft and the steel sleeve, which increases the labor intensity of the workers. Utility Model Content

[0004] The purpose of this application is to provide a steel sleeve welding machine to solve the problem of high labor intensity in existing steel sleeve welding machines.

[0005] To achieve the above objectives, the technical solution adopted in the embodiments of this application is as follows:

[0006] A steel sleeve welding machine is provided, comprising:

[0007] The transfer mechanism includes a first slide rail, a first sliding drive member, and a clamping mechanism. The first sliding drive member drives the clamping mechanism to slide on the first slide rail. The clamping mechanism includes a first bracket, a rotary drive member, and a clamp. The first bracket is slidably mounted on the first slide rail. The rotary drive member is mounted on the first bracket. The rotary drive member drives the clamp to rotate around a first horizontal axis. The clamp is used to clamp and release the rotor assembly.

[0008] A welding mechanism and an inspection mechanism are arranged at intervals along the first slide rail. The welding mechanism is used to weld the steel sleeve and the shaft of the rotor assembly, and the inspection mechanism is used to inspect the welding quality of the rotor assembly.

[0009] In one embodiment, the clamp includes a pneumatic drive and two grippers. The pneumatic drive is mounted on the output end of the rotary drive, and one end of each gripper is spaced apart from the output end of the pneumatic drive. The pneumatic drive drives the ends of the two grippers to rotate so that the other ends of the two grippers move closer to or further away from each other.

[0010] In one embodiment, the gripper is equipped with a clamping block located on the side of the gripper near the other gripper, and the side of the clamping block near the other gripper has a conforming arc surface.

[0011] In one embodiment, the clamping block has a first air passage that extends through the fitting arc surface and is connected to an external suction mechanism to adsorb the rotor assembly that is fitted to the fitting arc surface.

[0012] In one embodiment, the rotary drive is mounted on the first bracket via a telescopic drive, and the telescopic drive, the rotary drive, and the clamp are distributed sequentially along the first horizontal axis. The telescopic drive is used to drive the rotary drive to move along the first horizontal axis.

[0013] In one embodiment, the telescopic drive member is vertically mounted on the first bracket, and the clamping mechanism further includes a first lifting drive member, which is used to drive the telescopic drive member to perform a lifting movement.

[0014] In one embodiment, the first bracket is provided with a second slide rail that extends vertically, and the telescopic drive member is slidably mounted on the second slide rail via a first adapter plate. The first lifting drive member is located on top of the first adapter plate and drives the first adapter plate to slide along the second slide rail.

[0015] In one embodiment, the welding mechanism includes a second support and two welding torches. Each welding torch is vertically mounted on the second support via an independent second lifting drive. The two welding torches are located on opposite sides of a first vertical axis, and the ends of the welding torches are inclined from top to bottom toward the direction close to the first vertical axis.

[0016] In one embodiment, the welding mechanism further includes a dust collection assembly, which includes a second sliding drive, an air suction component, and a dust collection box. The second sliding drive is mounted on the second bracket, and the air suction component and the dust collection box are mounted vertically at intervals at the output end of the second sliding drive and slide horizontally toward the welding torch under the drive of the second sliding drive.

[0017] In one embodiment, the detection mechanism includes a third support, a detection platform, a third lifting drive, and a camera. The detection platform is used to position the positioning through hole of the rotor assembly. The third lifting drive is installed at the bottom of the detection platform, and the output shaft of the third lifting drive extends into the positioning through hole to drive the rotor assembly to perform lifting and lowering movements. The camera is installed on the third support and is located directly above the positioning through hole.

[0018] The steel sleeve welding machine provided in this application embodiment has at least the following beneficial effects: The clamping mechanism clamps the rotor assembly with a fixture and slides to the welding mechanism under the drive of the first sliding drive member. The welding mechanism performs welding operations on one end of the rotor assembly. Then, the rotary drive member drives the fixture to rotate around the first horizontal axis, realizing the flipping of the fixture and the rotor assembly. The welding mechanism then performs welding operations on the other end of the rotor assembly. After welding is completed, the clamping mechanism slides to the detection mechanism under the drive of the first sliding drive member for welding quality detection. The rotary drive member (such as a servo motor or pneumatic motor) drives the fixture to rotate 180° around the first horizontal axis, automatically completing the switching of the welding surfaces at both ends of the rotor assembly. This eliminates the need for manual flipping by workers, reducing labor intensity and improving production efficiency. Simultaneously, workers do not need to approach the welding mechanism, reducing the risk of burns and electric shocks. Attached Figure Description

[0040] The rotor assembly 10 includes a shaft 11, a steel sleeve 12, an iron core, and permanent magnets. The iron core is fixedly sleeved on the shaft 11, and multiple permanent magnets are fixedly installed on the iron core along the circumference of the iron core. The steel sleeve 12 is sleeved on the permanent magnets and fixed to the shaft 11 by welding, thereby ensuring the stability of the permanent magnet position during high-speed operation, improving the slot fill factor of the rotor assembly 10, and reducing the electrical density and copper loss of the rotor assembly 10.

[0041] Please see Figure 2 and Figure 3 The steel sleeve welding machine provided in the embodiments of this application will now be described. The steel sleeve 12 welding machine includes a transfer mechanism 100, a welding mechanism 200, and a detection mechanism 300.

[0042] The transfer mechanism 100 includes a first slide rail 110, a first sliding drive member 120, and a clamping mechanism 130. The first sliding drive member 120 drives the clamping mechanism 130 to slide on the first slide rail 110. The clamping mechanism 130 includes a first bracket 140, a rotary drive member 150, and a clamp 160. The first bracket 140 is slidably mounted on the first slide rail 110, and the rotary drive member 150 is mounted on the first bracket 140. The rotary drive member 150 drives the clamp 160 to rotate around a first horizontal axis X. The clamp 160 is used to clamp and release the rotor assembly 10.

[0043] The welding mechanism 200 and the inspection mechanism 300 are arranged at intervals along the first slide rail 110. The welding mechanism 200 is used to weld the steel sleeve 12 and the rotating shaft 11 of the rotor assembly 10, and the inspection mechanism 300 is used to inspect the welding quality of the rotor assembly 10.

[0044] In this embodiment, the clamping mechanism 130 clamps the rotor assembly 10 via the clamp 160 and slides to the welding mechanism 200 under the drive of the first sliding drive member 120. The welding mechanism 200 performs welding operations on one end of the rotor assembly 10. Then, the rotation drive member 150 drives the clamp 160 to rotate around the first horizontal axis X, realizing the flipping of the clamp 160 and the rotor assembly 10. The welding mechanism 200 then performs welding operations on the other end of the rotor assembly 10. After welding is completed, the clamping mechanism 130 slides to the detection mechanism 300 under the drive of the first sliding drive member 120 for welding quality detection. The rotation drive member 150 (such as a servo motor or pneumatic motor) drives the clamp 160 to rotate 180° around the first horizontal axis X, automatically completing the switching of the welding surfaces at both ends of the rotor assembly 10. This eliminates the need for manual flipping by workers, reducing labor intensity and improving production efficiency. Simultaneously, workers do not need to approach the welding mechanism 200, reducing the risk of burns and electric shocks.

[0045] In one embodiment, see Figure 3 and Figure 4 As a specific embodiment of the steel sleeve 12 welding machine provided in this application, the clamp 160 includes a pneumatic drive 161 and two grippers 162. The pneumatic drive 161 is mounted on the output end of the rotary drive 150, and one end of each gripper 162 is spaced apart from the output end of the pneumatic drive 161. The pneumatic drive 161 drives the ends of the two grippers 162 to rotate, so that the other ends of the two grippers 162 move closer to or further away from each other. The two grippers 162 open and close synchronously through the rotation of their ends, thereby clamping and releasing the rotor assembly 10.

[0046] In one embodiment, see Figure 3 and Figure 4As a specific embodiment of the steel sleeve 12 welding machine provided in this application, the gripper 162 is equipped with a clamping block 163. The clamping block 163 is located on the side of the gripper 162 near the other gripper 162, and the side of the clamping block 163 near the other gripper 162 has a conforming arc surface 164. The conforming arc surface 164 is adapted to the side profile of the steel sleeve 12 of the rotor assembly 10, with a larger contact area, which can evenly distribute the clamping force and prevent the rotor assembly 10 from slipping or shifting due to uneven force during welding or movement, thus ensuring the accuracy of the processing position.

[0047] In one embodiment, see Figure 3 and Figure 4 As a specific implementation of the steel sleeve 12 welding machine provided in this application, the clamping block 163 can be made of wear-resistant rubber, nylon and other elastic materials. By conforming to the arc surface 164, the clamping force is further buffered, while avoiding direct rigid contact between the metal claws 162 and the rotor assembly 10, thus reducing the risk of collision damage.

[0048] In one embodiment, see Figure 3 and Figure 4 As a specific embodiment of the steel sleeve 12 welding machine provided in this application, the clamping block 163 has a first air passage 165 that passes through the fitting arc surface 164. The first air passage 165 is connected to an external suction mechanism to adsorb the rotor assembly 10 that is fitted to the fitting arc surface 164. The adsorption force allows the rotor assembly 10 to be tightly fitted to the fitting arc surface 164, achieving uniform force distribution across the entire surface. When the rotor assembly 10 is rotated 180°, the adsorption force can counteract the centrifugal force, ensuring that the rotor assembly 10 remains in contact with the fitting arc surface 164 at all times.

[0049] In one embodiment, see Figure 3 and Figure 4 As a specific embodiment of the steel sleeve 12 welding machine provided in this application, the rotary drive 150 is mounted on the first bracket 140 via the telescopic drive 170. The telescopic drive 170, the rotary drive 150 and the clamp 160 are distributed sequentially along the first horizontal axis X. The telescopic drive 170 is used to drive the rotary drive 150 to move along the first horizontal axis X.

[0050] The telescopic drive component 170 (such as an electric push rod or cylinder) can drive the rotary drive component 150 and the clamp 160 to move along the first horizontal axis X, so that the rotor assembly 10 moves to directly below the welding torch 220 during welding, avoiding welding dead angles caused by the clamp 160 or the first bracket 140 blocking.

[0051] In one embodiment, see Figure 3 and Figure 4As a specific embodiment of the steel sleeve 12 welding machine provided in this application, the telescopic drive member 170 is vertically mounted on the first bracket 140, and the clamping mechanism 130 further includes a first lifting drive member 180, which drives the telescopic drive member 170 to perform lifting movements. The height of the rotor assembly 10 is adjusted by the first lifting drive member 180 so that the rotor assembly 10 meets the welding requirements or is smoothly transferred to the detection mechanism 300.

[0052] In one embodiment, see Figure 3 and Figure 4 In one specific embodiment of the steel sleeve 12 welding machine provided in this application, the first support 140 is provided with a second slide rail 141, which extends vertically. A telescopic drive member 170 is slidably mounted on the second slide rail 141 via a first adapter plate 142. A first lifting drive member 180 is located on top of the first adapter plate 142 and drives the first adapter plate 142 to slide along the second slide rail 141. The second guide rail ensures the straightness of the vertical movement.

[0053] In one embodiment, see Figure 5 and Figure 6 As a specific embodiment of the steel sleeve 12 welding machine provided in this application, the welding mechanism 200 includes a second support 210 and two welding torches 220. Each welding torch 220 is vertically mounted on the second support 210 via an independent second lifting drive 230. The two welding torches 220 are located on the horizontal sides of the first vertical axis Y, and the ends of the welding torches 220 are inclined from top to bottom toward the direction close to the first vertical axis Y.

[0054] In this application, the rotor assembly 10 is clamped in the fixture 160. Two welding torches 220 are located on both sides of the first vertical axis Y, and welding is performed simultaneously. This improves welding efficiency and balances the heat input during the welding process, reducing axial displacement or radial deformation of the rotor assembly 10 caused by unilateral heating. The two welding torches 220 can be raised and lowered independently, allowing welding to different height positions of the rotor assembly 10.

[0055] The rotating shaft 11 is erected in the center of the steel sleeve 12, and the welding operation space formed between the outer edge of the rotating shaft 11 and the inner edge of the steel sleeve 12 is small. In this embodiment, the end of the welding torch 220 is inclined, which can reduce the space occupied near the first vertical axis Y, reduce the welding operation space occupied, and allow welding to be performed in small spaces or special positions where the weld point is close to the rotating shaft 11.

[0056] Each welding torch 220 is connected to the second lifting drive 230 via an elastic element 231. The welding torch 220 is driven to descend by the second lifting drive 230. When it comes into contact with the rotor assembly 10, the elastic element 231 can absorb the instantaneous impact force, preventing the electrode 221 of the welding torch 220 from deforming or cracking due to rigid collision.

[0057] In one embodiment, see Figure 6 and Figure 7 As a specific embodiment of the steel sleeve 12 welding machine provided in this application, the welding mechanism 200 further includes a dust collection component 240. The dust collection component 240 includes a second sliding drive member 241, an air suction member 242, and a dust collection box 243. The second sliding drive member 241 is mounted on the second bracket 210. The air suction member 242 and the dust collection box 243 are installed vertically at intervals at the output end of the second sliding drive member 241 and slide horizontally toward the welding torch 220 under the drive of the second sliding drive member 241.

[0058] The high-temperature welding slag generated during welding is adsorbed by the suction component 242 and moves backward. At the same time, the welding slag particles fall under the action of gravity and fall directly into the dust collection box 243 below in a parabolic trajectory.

[0059] The second sliding drive component 241 is offset from the welding torch 220, rotor assembly 10, and clamping mechanism 130 on the first horizontal axis X to avoid occupying the narrow welding operation space. When the welding torch 220 stops its lifting motion, the second sliding drive component 241 drives the suction component 242 and dust collection box 243 to move closer to the welding torch 220 to avoid interference.

[0060] In one embodiment, as a specific implementation of the rotor welding magnetizer provided in this application, the number of suction components 242 is two. The two suction components 242 are set at the same height and are located on both sides of the first vertical axis Y. Then, a local low-pressure area is formed between the two suction components 242, which causes the welding slag to converge towards the middle and accelerate its settling into the dust collection box 243, thus avoiding the horizontal splashing of welding slag.

[0061] In one embodiment, as a specific implementation of the rotor welding magnetizer provided in this application, the welding mechanism 200 further includes an exhaust duct 250, the inlet of which is located below the dust collection assembly 240, to absorb any residue missed by the dust collection assembly 240.

[0062] In one embodiment, see Figure 8As a specific embodiment of the steel sleeve 12 welding machine provided in this application, the detection mechanism 300 includes a third support 310, a detection table 320, a third lifting drive 330, and a camera 340. The detection table 320 is used to position the positioning through hole 321 of the rotor assembly 10. Optionally, after the clamping mechanism 130 places the rotor assembly 10 into the positioning through hole 321, it can slide away from the detection mechanism 300 to achieve continuous operation. The third lifting drive 330 is installed at the bottom of the detection table 320, and the output shaft of the third lifting drive 330 extends into the positioning through hole 321 to drive the rotor assembly 10 to perform lifting and lowering movements. The camera 340 is installed on the third support 310 and is located directly above the positioning through hole 321.

[0063] The inspection table 320 achieves hole-shaft positioning through the positioning through hole 321 of the rotor assembly 10, avoiding false detections caused by positional offset. The output shaft of the third lifting drive 330 extends into the positioning through hole 321, driving the rotor assembly 10 to rise and approach the camera 340, adopting a vertical overhead shooting perspective, which can completely eliminate perspective distortion.

[0064] Furthermore, stable positioning and shooting angles provide high-quality training data for deep learning detection models.

[0065] In one embodiment, see Figure 8 As a specific embodiment of the steel sleeve 12 welding machine provided in this application, the inspection mechanism 300 includes a protective cover 350, which is located between the camera 340 and the inspection table 320. The protective cover 350 has a light-transmitting area for light to pass through. The protective cover 350 prevents metal dust and cutting fluid droplets generated during processing from adhering to the lens.

[0066] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0067] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
