Technical Field

[0001] The present invention relates to the technical field of welding devices, and in particular to a welding device for machining a motor stator core. Background Art

[0002] Existing core machining and welding devices usually directly place the stacked cores on the workbench, and then weld the cores with a welding gun. However, after welding in this way, it is necessary to wait for a certain period of time for cooling, and then the staff takes out the cores and places the cores to be welded again, which will consume more time and reduce work efficiency.

[0003] Those skilled in the art have conducted research and improvement on this. A stator core machining and welding device with the application number CN202420987646.2. This technical solution rotates the rotating seat for core loading and unloading, drives the turntable to rotate through the connecting plate, and can adjust the position of the welding gun. However, when using this technical solution, only the pressing ring is used for pressing and limiting, which cannot ensure the alignment of each punching piece of the core, is not conducive to ensuring the subsequent welding effect, and requires manual unloading after welding, which is not conducive to reducing the labor intensity.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. The structure of the present invention is reasonably designed. After the traction rod deflects, the I-shaped slider moves along the guide through groove. The prism rod can abut against the inner wall of the punching sheet for positioning. By using the driving gear to mesh and drive the straight tooth ring, the stator core can be switched between workstations after the positioning table rotates, which is convenient for the welding work. The cylindrical block is coaxially arranged with the steering shell and can rotate synchronously to avoid interference.

[0018] 2. The lateral position of the support seat in the present invention is adjustable.

The upper end of the prism rod abuts against the lower surface of the pre-pressing plate to avoid interference with the punching sheet pressing;

[0019] 3. In the present invention, the rectangular frame rises and falls synchronously with the linkage block, and the relative position of the welding assembly and the stator core is adjustable, so that the welding stations can correspond to the oblique bracket and the fixed bracket in sequence. The burrs at the welding position are ground and pre-processed by the high-speed rotation of the grinding disc to ensure the quality of subsequent welding. The welding gun can weld at the corresponding position to produce welds, and the cooling fan is used to accelerate the cooling of the welds. The function is diverse. With the adjustment of the orientation of the steering shell, multiple welds are finally completed on the outside of the stator core to ensure the processing and welding effect.

[0020] 4. After welding is completed in the present invention, the pre-pressing plate is separated from the upper end of the stator core, and the position of the unloading rack is adjusted by moving the sliding sleeve along the guide rail. The electromagnet is energized to adsorb the metal block, and the arc block can fit the outer wall of the stator core. The height of the clamping arm is adjusted by the second electric push rod, which is convenient for clamping and transporting the stator core. The guide roller is used for unloading and transfer, which reduces labor intensity.

[0021] In summary, the device has various functions, can ensure welding effect, reduce labor intensity, and is suitable for popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS

A PLC controller 13 is connected to the outer wall of the workbench 1.

[0047] Four guiding through-slots 501 are circumferentially opened on the top of the positioning table 5. An I-shaped slider 502 is slidably connected in the guiding through-slots 501. A triangular through-hole 503 is opened in the I-shaped slider 502. A prism rod 504 is movably inserted in the triangular through-hole 503. The lower end of the prism rod 504 is connected with a stop block 505. A tension spring 506 is connected between the stop block 505 and the I-shaped slider 502. A lifting seat 507 is arranged below the positioning table 5. A hydraulic rod 508 is connected between the lifting seat 507 and the workbench 1. A cylindrical block 509 is rotatably connected in the lifting seat 507. A traction rod 510 is hinged between the upper end of the cylindrical block 509 and the side wall of the I-shaped slider 502. The cylindrical block 509 and the steering shell 4 are coaxial. A first raceway 511 is opened between the positioning table 5 and the workbench 1.

[0048] The right end of the round through port 3 is communicated with a receiving cavity 301. The bottom of the workbench 1 is connected with a steering motor 302. The top output end of the steering motor 302 is connected with a driving gear 303. The middle part of the outer wall of the steering housing 4 is connected with a straight gear ring 401. One end of the driving gear 303 extending out of the receiving cavity 301 is meshed and connected with the straight gear ring 401. The bottom of the outer wall of the steering housing 4 is connected with an annular plate 402. A second raceway 403 is formed between the annular plate 402 and the workbench 1.

[0051] Embodiment Two

[0052] On the basis of Embodiment One, a vertical groove 701 is opened on the left end face of the vertical frame 7. The top of the inner cavity of the vertical groove 701 is connected with a conveying motor 702. The bottom output end of the conveying motor 702 is connected with a vertical lead screw 703. A linkage block 704 is threadedly connected to the outer wall of the vertical lead screw 703, which is convenient for adjusting the working height of the welding assembly 8. The top of the right end face of the vertical frame 7 is connected with an extension seat 705. The right side of the bottom wall of the extension seat 705 is connected with a first electric push rod 706. The lower end of the first electric push rod 706 is rotatably connected with a pre-pressing plate 707, which is convenient for pressing the stator core and ensuring the welding quality.

[0053] The welding assembly 8 includes a rectangular frame 801. The left side of the inner wall of the rectangular frame 801 is fixedly connected with the linkage block 704. The right end of the rectangular frame 801 is connected with a fixing frame 802. A welding torch 803 is connected in the fixing frame 802. The front and rear ends of the rectangular frame 801 are symmetrically connected with inclined brackets 804. A grinding motor 805 is embedded in the front inclined bracket 804. The output end of the grinding motor 805 is connected with a grinding disc 806. A cooling fan 807 is embedded in the rear inclined bracket 804, with diverse functions.

[0054] Both the front and the back of the left part of the workbench 1 are provided with stroke grooves 101. A longitudinal through groove 102 is communicated between the right ends of the two stroke grooves 101. A transverse lead screw 103 is rotatably connected in the stroke groove 101. A nut seat 104 is threadedly connected to the outer part of the transverse lead screw 103. A side support plate 105 is connected to the outer wall of the nut seat 104. The upper end of the side support plate 105 is fixedly connected to the bottom wall of the support seat 6. A synchronous pulley 106 is connected to the right side of the outer wall of the transverse lead screw 103. A synchronous belt 107 is sleeved between the outer walls of the two synchronous pulleys 106. The synchronous belt 107 penetrates through the longitudinal through groove 102. A driving motor 108 is connected to the left end of the workbench 1. The output end of the driving motor 108 is connected to the transverse lead screw 103 through a coupling. The position of the support seat 6 is adjustable, which is convenient for the processing, loading and unloading of the stator core.

[0055] A limit block 109 is connected to the left side of the top of the workbench 1. When the support seat 6 abuts against the limit block 109, the intersection of the axis lines of the welding torch 803, the grinding disc 806 and the cooling fan 807 coincides with the axis line of the steering shell 4, so that grinding, welding and cooling can be sequentially carried out when the welding station is switched. When the support seat 6 abuts against the limit block 109, the first electric push rod 706 and the steering shell 4 are coaxially arranged. The pre-pressing plate 707 can rotate synchronously with the steering shell 4 to ensure the pressing effect.

[0056] The specific implementation mode of this embodiment is as follows:

[0057] When the device is in use, the synchronous pulley 106 and the synchronous belt 107 are used for cooperative transmission. After the driving motor 108 is started, the two transverse lead screws 103 rotate synchronously. The nut seat 104 can drive the side support plate 105 to move horizontally, so as to adjust the horizontal position of the support seat 6. When the right end of the support seat 6 contacts the limit block 109, the working position is reached. The first electric push rod 706 is used to drive the pre-pressing plate 707 to press down, so that the punching sheet of the stator core can be pressed between the pre-pressing plate 707 and the positioning table 5, avoiding the influence on the welding effect due to too large a gap. Through the arrangement of the tension spring 506 and the stop block 505, the lower end position of the prism rod 504 is variable. The upper end of the prism rod 504 abuts against the lower surface of the pre-pressing plate 707 and will not interfere with the pressing of the punching sheet of the stator core;

[0058] The conveying motor 702 drives the vertical lead screw 703 to rotate, and the linkage block 704 drives the rectangular frame 801 to lift and lower, so that the relative position between the welding assembly 8 and the stator core changes. The welding stations for positioning the core correspond to the inclined bracket 804 and the fixing bracket 802 in sequence. The grinding motor 805 drives the grinding disc 806 to rotate at a high speed. During the lifting and lowering process of the rectangular frame 801, the grinding disc 806 can perform grinding pretreatment on the burrs at the welding position to ensure the subsequent welding quality. The welding torch 803 performs welding work at the corresponding position to generate welds, and the cooling fan 807 accelerates the cooling of the welds. It has various functions. By adjusting the orientation of the steering housing 4, multiple welds can be completed outside the stator core to ensure the processing and welding effect.

[0059] Embodiment 3

[0060] On the basis of Embodiment 2, a transverse tooth groove 901 is provided at the top of the guide rail 9, a relief opening 1001 is provided at the upper end of the sliding sleeve 10, a discharging motor 1101 is connected to the top of the discharging frame 11, the output end of the discharging motor 1101 is connected to a driving gear 1102, one end of the driving gear 1102 passing through the relief opening 1001 is meshed and connected to the transverse tooth groove 901, an electric push rod II 1103 is connected to the center of the discharging frame 11, and the output end of the electric push rod II 1103 is connected to a clamping arm 1104.

[0061] U-shaped rods 1141 are movably inserted at the front and rear ends of the clamping arm 1104. An arc block 1142 is connected to the end of the U-shaped rod 1141. A return spring 1143 is connected between the arc block 1142 and the inner wall of the clamping arm 1104. Anti-slip protrusions 1144 are provided on one side where the two arc blocks 1142 are close to each other to increase the friction for easy clamping and moving. Electromagnets 1145 are connected to the front and rear of the outer wall of the clamping arm 1104, and metal blocks 1146 are connected to the horizontal part of the U-shaped rod 1141.

[0062] The distance dimension between the horizontal parts of the two U-shaped rods 1141 is smaller than the distance dimension between the two guide rails 9, which is convenient for clamping and moving the stator core. Side guard plates 1201 are connected to the front and rear of the bottom of the discharging port 12, and a plurality of guide rollers 1202 are rotatably connected between the two side guard plates 1201. A protective rubber sleeve 1203 is sleeved on the outer wall of the guide roller 1202 to reduce bump damage.

[0063] The specific implementation method of this embodiment is as follows:

[0064] In this embodiment, after welding is completed, the support base 6 is controlled to move leftward, and the pre-pressing plate 707 disengages from the upper end of the stator core. By using the cooperation and transmission of the driving gear 1102 and the transverse tooth grooves 901, when the unloading motor 1101 is started, the sliding sleeve 10 can move horizontally along the guide rail 9. When the sliding sleeve 10 moves to the left end of the guide rail 9, the two arc-shaped blocks 1142 are located on the front and rear sides of the stator core. By energizing the electromagnet 1145 to adsorb the metal block 1146, the arc-shaped blocks 1142 are attached to the outer wall of the stator core for clamping. The clamping arm 1104 is driven to move upward by the electric push rod II 1103. After the stator core is higher than the prism rod 504, the unloading motor 1101 is controlled to turn over, and the stator core can be moved above the guide roller 1202. After the electromagnet 1145 is powered off, the return spring 1143 performs elastic reset. After the arc-shaped blocks 1142 are loosened, the stator core falls onto the lower guide roller 1202, which is convenient for unloading and transferring, and reduces the labor intensity.
