Description

Technical Field

[0001] This invention relates to the field of spot welding equipment, specifically a rotor spot welding machine for rotor production. Background Technology

[0002] Rotor spot welding is a localized welding process for rotor components in equipment such as motors and generators. By applying pressure to electrodes and passing a short current through them, tiny weld points are formed on the rotor core laminations or specific connection points to fix the components together. Currently, spot welding machines are mostly used in rotor production to complete welding operations. To ensure operational safety during the welding process and to facilitate operators in timely detection of welding deviations (such as weld point misalignment, cold welds, etc.), semi-automatic spot welding machines are still widely used in the industry. These machines require manual assistance to complete processes such as material loading, positioning, and post-weld inspection. They have the advantages of flexible operation and low cost in small and medium batch production scenarios.

[0003] However, semi-automatic rotor spot welding machines generate a large amount of welding slag during the welding process. This slag is prone to splashing at high temperatures, which can not only contaminate the workbench and surrounding precision parts, but also burn operators, posing a safety hazard. At the same time, dust and oxide layers are easily attached to the rotor surface during the initial processing. If not cleaned in time, it can lead to uneven current conduction during spot welding, causing problems such as incomplete welding and insufficient weld nugget, which seriously affects the welding strength. In addition, unloading after welding relies on manual handling. The rotor weld area still retains residual heat after cooling, and the rotor is prone to slipping and collision when handled manually, causing burns to the hands. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-9 The present invention provides a technical solution: a rotor spot welding machine for rotor production, including a workbench 1, a clamping and rotating device 8 installed on the workbench 1, a spot welding device 9 installed on the workbench 1, a material unloading structure 2 installed on the workbench 1, a dust removal structure 5 installed on the workbench 1, and a collection structure 6 installed on the workbench 1. The unloading structure 2 includes two guide frames 201 fixedly connected to the workbench 1 and a connecting frame 202 slidably connected to the guide frames 201. A slider 203 is slidably connected to the connecting frame 202. A fixed shaft 204 is rotatably connected to the slider 203. A connecting block 205 is fixedly connected to the fixed shaft 204. A wear-resistant plate 206 is detachably connected to the connecting block 205. The fixed shaft 204 is slidably connected to the connecting frame 202. A drive shaft 214 is rotatably connected to the connecting frame 202. The fixed shaft 204 is provided with a straight groove 208 and a spiral groove 209. A clamping structure 3 is provided on the connecting block 205. A collection box 7 is installed on the workbench 1.

[0022] A first lead screw 207 is rotatably connected to one of the guide frames 201. A connecting frame 202 is threadedly connected to the first lead screw 207. A guide shaft 210 is fixedly connected to the guide frame 201, and the connecting frame 202 is slidably connected to the guide shaft 210. A scale bar 211 is provided on the guide frame 201. A protective cover 212 is fixedly connected to the connecting frame 202. A slider 203 is slidably connected to the protective cover 212. A first driving member 213 is installed on the connecting frame 202. The first lead screw 207 is driven by the first driving member 213, and the clamping structure... The structure 3 includes two slide rods 301 slidably connected to the connecting block 205 and a rubber pad 302 fixedly connected to the slide rods 301. An adjusting block 303 is fixedly connected to the slide rods 301 and slidably connected to the connecting block 205. A second lead screw 304 is rotatably connected to the connecting block 205. The adjusting block 303 and the second lead screw 304 are threadedly connected. The threads at both ends of the second lead screw 304 are in opposite directions. A second driving member 305 is installed on the connecting block 205 and the second lead screw 304 is driven by the second driving member 305.

[0023] In practical use, after the welding operation is completed, the second drive unit 305 (preferably a motor) is activated. The second drive unit 305 drives the second lead screw 304 to rotate. Since the threads at both ends of the second lead screw 304 are in opposite directions, the two adjusting blocks 303 connected to it will synchronously drive the slide rod 301 to slide towards each other along the connecting block 205 until the rubber pad 302 at the end of the slide rod 301 is tightly attached to the outer wall of the rotor end ring. At this time, the first drive unit 213 (preferably a motor) is activated. The first drive unit 213 drives the first lead screw 207 to rotate, causing the connecting frame 202 to slide along the guide shaft 210 of the guide frame 201. The guide shaft 210 can limit the sliding direction of the connecting frame 202, prevent it from shifting laterally, and ensure the accuracy of the unloading path. Meanwhile, the drive shaft 214 on the connecting frame 202 will roll in cooperation with the spiral groove 209 and straight groove 208 of the fixed shaft 204. When the spiral groove 209 moves to the drive shaft 214, the spiral groove 209 will drive the fixed shaft 204 to rotate along the slider 203. Then the second drive component 305 rotates in the opposite direction, the slide rod 301 releases the rotor, and finally the connecting block 205 drives the welded rotor to roll down to the top of the collection box 7. The rotor falls smoothly into the collection box 7 to complete the unloading. There is no need for manual contact with the high-temperature rotor, avoiding burns to the operator and improving the safety of the operation. The scale strip 211 on the guide frame 201 can help the operator to accurately adjust the height of the wear-resistant plate 206 according to the rotor length specification to adapt to the spot welding of different models of rotors.

[0024] The wear-resistant plate 206 is mounted on the connecting block 205 via the mounting structure 4. The mounting structure 4 includes a mounting block 401 slidably connected to the connecting block 205 and a guide post 402 fixedly connected to the connecting block 205. The mounting block 401 engages with the wear-resistant plate 206. A guide rail 405 is fixedly connected to the wear-resistant plate 206. The guide rail 405 is slidably connected to the connecting block 205. A pressing rod 403 is fixedly connected to the mounting block 401. The pressing rod 403 is slidably connected to the guide post 402. A first spring 404 is fixedly connected between the pressing rod 403 and the connecting block 205.

[0025] In practical use, when the wear-resistant plate 206 wears due to long-term contact with the rotor, the operator only needs to press the pressing rod 403. The pressing rod 403 compresses the first spring 404 and drives the mounting block 401 to disengage from the slot of the wear-resistant plate 206. Then, the old wear-resistant plate 206 can be pulled out along the guide rail 405 to replace the new part. The whole process does not require disassembling the connecting block 205, which greatly improves the equipment maintenance efficiency.

[0026] The dust removal structure 5 includes a dust collection hood 501 fixedly connected to the workbench 1 and a mounting frame 502 fixedly connected to the dust collection hood 501. A sliding frame 503 is slidably connected to the mounting frame 502. A cleaning brush 505 is rotatably connected to the sliding frame 503. A third driving component 504 is installed in the sliding frame 503. The cleaning brush 505 is driven by the third driving component 504. A fourth driving component 507 is installed on the mounting frame 502. The sliding frame 503 is driven by the fourth driving component 507. A protective plate 506 is fixedly connected to the cleaning brush 505.

[0027] In practical use, the operator places the rotor blank to be welded onto the clamping and rotating device 8 on the worktable 1. The pneumatic grippers of the clamping and rotating device 8 automatically clamp the rotor journal, and its built-in servo motor starts, driving the rotor to rotate smoothly at a preset speed. This rotation function can cooperate with the subsequent spot welding device 9 to achieve continuous welding in the circumferential direction of the rotor. After the rotor is positioned, the third drive component 504 (preferably a motor) and the fourth drive component 507 (preferably a hydraulic rod) are activated. The third drive component 504 drives the cleaning brush 505 to rotate, cooperating with the clamping and rotating device 8 to rotate the rotor. The cleaning brush 505 can effectively grind the copper oxide layer and dust impurities on the rotor. At the same time, after cleaning is completed, the fourth drive component 504... 7. The drive slide frame 503 slides along the mounting frame 502, causing the cleaning brush 505 to retract into the mounting frame 502. The protective plate 506 on the outside of the cleaning brush 505 can block the welding slag during the welding process and prevent damage to the cleaning brush 505. After cleaning, the spot welding device 9 is started. The electric push rod drives the spot welding head to move back and forth to the preset welding position. The spot welding current and welding pressure are automatically adjusted according to the thickness of the rotor end ring. During the spot welding process, the clamping and rotating device 8 continuously drives the rotor to rotate slowly, so that the spot welding device 9 can form weld points evenly along the circumference of the rotor. The temperature sensor built into the spot welding head will provide real-time feedback on the temperature of the welding area. When the temperature exceeds the threshold, the control system automatically reduces the current to ensure the stability of the welding quality.

[0028] The collection structure 6 includes a collection frame 601 mounted on the workbench 1 and a fixed frame 602 slidably connected to the collection frame 601. A filter screen 603 is fixedly connected to the fixed frame 602. A vacuum pump 604 is mounted on the workbench 1. A first flexible hose 605 is installed on the suction pipe of the vacuum pump 604. The other end of the first flexible hose 605 is mounted on the fixed frame 602. A guide rod 606 is fixedly connected to the fixed frame 602. A fixed sleeve 607 is fixedly connected to the workbench 1. The guide rod 606 and the fixed sleeve 607 are slidably connected. A second flexible hose 610 is fixedly connected between the workbench 1 and the dust collection hood 501. The second flexible hose 610 is connected to one side of the filter screen 603. A second spring 608 is fixedly connected between the guide rod 606 and the fixed sleeve 607. A vibration motor 609 is mounted on the fixed frame 602.

[0029] In practical use, the vacuum pump 604 and the vibration motor 609 are started simultaneously. The vacuum pump 604 draws the welding slag collected by the dust hood 501 into the collection frame 601 through the second hose 610. After being filtered by the filter screen 603, the welding slag remains in the fixed frame 602. The vibration motor 609 drives the fixed frame 602 to vibrate slightly. With the elastic buffer of the second spring 608, the welding slag can be effectively prevented from clogging the filter screen 603. At the same time, the guide rod 606 slides with the fixed sleeve 607, making the fixed frame 602 move more smoothly, so that the welding slag falls into the collection frame 601 for collection, avoiding the welding slag from scattering and contaminating the sensors and other precision components on the workbench 1, and reducing the risk of equipment failure.

[0030] Working principle: First, the operator places the rotor blank to be welded on the clamping and rotating device 8 of the worktable 1. The pneumatic grippers of the clamping and rotating device 8 automatically clamp the rotor journal, and its built-in servo motor starts, driving the rotor to rotate smoothly at a preset speed. This rotation function can cooperate with the subsequent spot welding device 9 to achieve continuous welding in the circumferential direction of the rotor. After the rotor is positioned, the third drive component 504 (preferably a motor) and the fourth drive component 507 (preferably a hydraulic rod) are activated. The third drive component 504 drives the cleaning brush 505 to rotate, which, together with the clamping and rotating device 8, makes the rotor rotate. The cleaning brush 505 can effectively polish the copper oxide layer and dust impurities on the rotor. At the same time, after cleaning is completed, the fourth drive component 507... 07 Drive the sliding frame 503 to slide along the mounting frame 502, causing the cleaning brush 505 to retract into the mounting frame 502. The protective plate 506 on the outside of the cleaning brush 505 can block the welding slag during the welding process and prevent damage to the cleaning brush 505. After cleaning, the spot welding device 9 is started. The electric push rod drives the spot welding head to move back and forth to the preset welding position. The spot welding current and welding pressure are automatically adjusted according to the thickness of the rotor end ring. During the spot welding process, the clamping and rotating device 8 continuously drives the rotor to rotate slowly, so that the spot welding device 9 can form weld points evenly along the circumference of the rotor. The temperature sensor built into the spot welding head will provide real-time feedback on the temperature of the welding area. When the temperature exceeds the threshold, the control system automatically reduces the current to ensure the stability of the welding quality. Simultaneously, vacuum pump 604 and vibration motor 609 are started. Vacuum pump 604 sucks the welding slag collected by dust hood 501 into collection frame 601 through second hose 610. After being filtered by filter screen 603, the welding slag remains in fixed frame 602. Vibration motor 609 drives fixed frame 602 to vibrate slightly. With the elastic buffer of second spring 608, welding slag can effectively prevent filter screen 603 from being blocked. At the same time, guide rod 606 slides with fixed sleeve 607, making fixed frame 602 move more smoothly, so that welding slag falls into collection frame 601 for collection, avoiding welding slag from scattering and contaminating precision components such as sensors on workbench 1, and reducing the risk of equipment failure. After welding is completed, the second drive unit 305 (preferably a motor) is activated. The second drive unit 305 drives the second lead screw 304 to rotate. Because the threads at both ends of the second lead screw 304 are in opposite directions, the two adjusting blocks 303 connected to it will synchronously drive the slide rod 301 to slide towards each other along the connecting block 205 until the rubber pad 302 at the end of the slide rod 301 is tightly attached to the outer wall of the rotor end ring. At this time, the first drive unit 213 (preferably a motor) is activated. The first drive unit 213 drives the first lead screw 207 to rotate, causing the connecting frame 202 to slide along the guide shaft 210 of the guide frame 201. The guide shaft 210 can limit the sliding direction of the connecting frame 202, prevent it from shifting laterally, and ensure the accuracy of the unloading path. The drive shaft 214 on the connecting frame 202 will roll with the spiral groove 209 and straight groove 208 of the fixed shaft 204. When the spiral groove 209 moves to the drive shaft 214, the spiral groove 209 will drive the fixed shaft 204 to rotate along the slider 203. Then the second drive component 305 rotates in the opposite direction, the slide bar 301 releases the rotor, and finally the connecting block 205 drives the welded rotor to roll down to the top of the collection box 7. The rotor falls smoothly into the collection box 7 to complete the unloading. There is no need for manual contact with the high temperature rotor, avoiding burns to the operator and improving the safety of the operation. The scale strip 211 on the guide frame 201 can help the operator to accurately adjust the height of the wear-resistant plate 206 according to the rotor length specification to adapt to the spot welding of different models of rotors. When the wear-resistant plate 206 wears out due to long-term contact with the rotor, the operator only needs to press the pressing rod 403. The pressing rod 403 compresses the first spring 404 and drives the mounting block 401 to disengage from the slot of the wear-resistant plate 206. Then, the old wear-resistant plate 206 can be pulled out along the guide rail 405 to replace the new part. The whole process does not require disassembling the connecting block 205, which greatly improves the equipment maintenance efficiency.
