Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a rotor welding equipment. Background Technology

[0002] Rotor welding equipment is a type of mechanical equipment specifically designed for welding motor rotors. The rotor is one of the core components of a motor, and its function is to generate electromotive force through rotation. During the manufacturing process, different parts of the rotor need to be firmly connected using welding technology to ensure its performance and durability. Rotor welding equipment is typically equipped with precise welding devices, such as arc welding, laser welding, or friction welding systems, to achieve high-quality welding results. These devices have automated control systems that allow for fine parameter adjustments to adapt to the welding requirements of different rotors. The equipment design also includes clamping and positioning devices to ensure stability and accuracy during the welding process. Through efficient welding technology, rotor welding equipment improves production efficiency and product quality, and is widely used in motor manufacturing and generator set fields.

[0003] A search revealed Chinese patent publication number CN205914886U, which discloses a rotor outer surface welding machine. The machine includes a worktable with a welding platform fixed above it. Columns are fixed on both sides of the welding platform, and a cylinder connecting plate is connected to the top of each column. A cylinder is vertically mounted in the middle of the cylinder connecting plate, and a rotor extrusion mold is connected to the cylinder piston rod. A square through-hole is provided on the worktable below the welding platform, and slide rails are provided on both sides of the square through-hole. The welding platform is hollow inside and has an opening on one side along the slide rail direction. A workpiece clamping mechanism is connected to the slide rail via a slider and can move along the length of the slide rail. The workpiece clamping mechanism can clamp the workpiece for vertical movement and rotation. A laser welding mechanism is provided on the welding platform, and a workpiece position detection feedback mechanism is provided on the outside of the welding platform. This invention can accurately weld the outer surface of a rotor, is stable and reliable, has a high degree of automation, and high welding efficiency. However, in actual use, when welding at multiple angles of the rotor, the device requires frequent manual disassembly and angle adjustment, resulting in low efficiency and increased workload for workers. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rotor welding device, which aims to improve the problem that the existing technology requires frequent manual disassembly and angle adjustment, resulting in low efficiency and increased workload for workers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rotor welding device, comprising an operating table, a grooved disc rotatably connected to the top center of the operating table, a servo motor fixedly connected to the bottom of the operating table, the output end of the servo motor passing through the operating table and the grooved disc and fixedly connected to a bevel gear one, a bevel gear two meshing with the outer wall of the bevel gear one, a threaded rod fixedly connected to the outer side of the bevel gear two, a clamping block threadedly connected to the outer side of the threaded rod, the clamping block slidably connected to the grooved disc, a cylinder fixedly connected to the bottom left side of the operating table, one end of the cylinder passing through the operating table and fixedly connected to an L-shaped plate, a laser welding device slidably connected to the top rear side of the L-shaped plate, a limiting hollow plate fixedly connected to the top left side of the operating table, and a moving mechanism provided on the top of the laser welding device for adjusting the position of the laser welding device.

[0006] The above technical solution involves placing the rotor to be processed on top of the grooved disc, then starting the servo motor to drive bevel gear one to rotate. Through the meshing of bevel gear one and bevel gear two, bevel gear two rotates, thereby driving the threaded rod on the rear to rotate. At this time, the clamping block on the outside of the threaded rod moves towards the center of the grooved disc. When multiple clamping blocks are in contact with the rotor, as the threaded rod continues to rotate, the clamping blocks can no longer move, thus stopping both the threaded rod and bevel gear two from moving. The continued rotation of bevel gear one allows the entire grooved disc to rotate. Simultaneously, the cylinder is activated to move the L-shaped plate up and down, adjusting the height of the laser welding equipment to weld at different positions on the rotor.

[0007] As a further description of the above technical solution: The moving mechanism includes a motor, the top of which is fixedly connected to the top of the laser welding equipment. A gear is fixedly connected to one end of the motor. A rack is fixedly connected to the front of the top of the laser welding equipment, and the rack meshes with the gear. A moving block is slidably connected to the right side of the top of the laser welding equipment. Rollers are rotatably connected to the upper and lower sides of the right side of the moving block. A fixing knob is provided on the right side of the top of the laser welding equipment, and the outer wall of the fixing knob penetrates through the laser welding equipment.

[0008] The above technical solution involves adjusting the position of the moving block during rotor welding, then fixing it by rotating the fixing knob. Starting the motor drives the gear to rotate, and the meshing connection between the gear and the rack allows the laser welding equipment to move left and right. During rotor rotation, the roller contacts the rotor, ensuring that the contact distance between the laser welding equipment and the rotor remains consistent. This ensures that the laser welding equipment outputs consistent energy to the welding position, thereby guaranteeing consistent welding results.

[0009] As a further description of the above technical solution: The inner wall of the limiting hollow plate is fixedly connected to slide rails on both the left and right sides, and the slide rails are slidably connected to the L-shaped plate.

[0010] The above technical solution allows the L-shaped plate to slide smoothly using a slide rail.

[0011] As a further description of the above technical solution: The top of the laser welding equipment is equipped with a dust suction pipe, and the right side of the dust suction pipe passes through the moving block and is connected to a conical suction nozzle.

[0012] The above technical solution allows for the connection of an external vacuum cleaner via a suction pipe, which then uses a conical nozzle to remove the fumes generated during welding.

[0013] As a further description of the above technical solution: An L-shaped light post is fixedly connected to the rear top of the operating table, and a lighting lamp is fixedly connected to the left side of the L-shaped light post.

[0014] The above technical solution provides additional lighting, making it easier to check for incomplete welding.

[0015] As a further description of the above technical solution: The outer wall of the clamping block is provided with multiple anti-slip grooves, and the top center of the grooved disc is provided with a limiting groove.

[0016] The above technical solution improves the anti-slip ability of the clamping block through the anti-slip groove and limits the position of the rotor through the limiting groove.

[0017] As a further description of the above technical solution: A limit block is fixedly connected to the top front left of the control panel, and a warning sign block is fixedly connected to the top of the limit block.

[0018] The above technical solution allows operators to be reminded to pay attention to safety through warning signs.

[0019] As a further description of the above technical solution: A protective cylinder is fixedly connected to the top center of the operating table, and an ultrasonic scanning device is fixedly connected to the front side of the inner wall of the protective cylinder.

[0020] The above technical solutions are as follows: the protective cylinder can prevent small impurities from flying out and injuring operators during rotating welding; and the ultrasonic scanning equipment can scan the welded rotor to determine whether the welding is complete.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the servo motor is started to make the first bevel gear rotate and mesh with the second bevel gear, which drives the threaded rod to rotate. The rotation of the threaded rod causes the clamping block to move towards the center of the grooved disc. After the clamping block contacts the rotor, the threaded rod and the second bevel gear stop rotating, while the first bevel gear continues to rotate, causing the grooved disc to rotate. At the same time, the cylinder moves the L-shaped plate up and down to adjust the height of the laser welding equipment so that welding can be performed on different positions of the rotor.

[0022] 2. In this utility model, after the moving block is adjusted and fixed, the motor is started to make the gear rotate. The gear meshes with the rack and drives the laser welding equipment to move left and right. When the rotor rotates, the roller contacts the rotor, which can maintain a constant distance from the welding device, ensure consistent welding energy, and ensure uniform welding effect.

[0025] 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.

[0026] Reference Figure 1 , Figure 4 and Figure 5 An embodiment of this utility model provides a rotor welding device, including an operating table 1. A grooved disc 8 is rotatably connected to the top center of the operating table 1. A servo motor 3 is fixedly connected to the bottom of the operating table 1. The output end of the servo motor 3 passes through the operating table 1 and the grooved disc 8 and is fixedly connected to a bevel gear 4. A bevel gear 5 is meshed with the outer wall of the bevel gear 4. A threaded rod 6 is fixedly connected to the outer side of the bevel gear 5. A clamping block 7 is threadedly connected to the outer side of the threaded rod 6. The clamping block 7 is slidably connected to the grooved disc 8.

A moving mechanism 2 is provided on the top of the laser welding device 11. The moving mechanism 2 is used to adjust the position of the laser welding device 11. Specifically, the rotor to be processed is placed on top of the grooved disc 8. Then, the servo motor 3 is started to drive the bevel gear 4 to rotate. Through the meshing of bevel gear 4 and bevel gear 5, bevel gear 5 rotates, thereby driving the threaded rod 6 on the rear side to rotate. At this time, the clamping block 7 on the outside of the threaded rod 6 will move towards the center of the grooved disc 8. When multiple clamping blocks 7 are in contact with the rotor, the clamping blocks 7 cannot move as the threaded rod 6 continues to rotate, thus causing the threaded rod 6 and bevel gear 5 to stop moving. The continued rotation of bevel gear 4 can make the entire grooved disc 8 rotate. At the same time, the cylinder 9 is started to drive the L-shaped plate 10 to move up and down, which can adjust the height of the laser welding equipment 11, thereby welding at different positions of the rotor.

[0027] Reference Figure 1 , Figure 2 and Figure 5 The moving mechanism 2 includes a motor 201, the top of which is fixedly connected to the top of the laser welding equipment 11. A gear 202 is fixedly connected to one end of the motor 201. A rack 203 is fixedly connected to the front of the top of the laser welding equipment 11. The rack 203 meshes with the gear 202. A moving block 204 is slidably connected to the top right side of the laser welding equipment 11. Rollers 205 are rotatably connected to the upper and lower sides of the right side of the moving block 204. A fixing knob 206 is provided on the top right side of the laser welding equipment 11. The outer wall of the fixing knob 206 penetrates the laser welding equipment 11. Specifically, when welding the rotor, first adjust the position of the moving block 204, then rotate the fixing knob 206 to fix it. By starting the motor 201, the gear 202 can be driven to rotate. Through the meshing connection between the gear 202 and the rack 203, the laser welding equipment 11 can be driven to move left and right. During the rotation of the rotor, the roller 205 contacts it, which can ensure that the contact distance between the laser welding equipment 11 and the roller is always consistent, thereby ensuring that the output energy of the laser welding equipment 11 to the welding position is consistent, thus ensuring that the welding effect of the welding point is consistent.

[0028] Reference Figure 1 , Figure 3 and Figure 5 The inner walls of the limiting hollow plate 12 are fixedly connected to slide rails 13 on both the left and right sides. The slide rails 13 are slidably connected to the L-shaped plate 10. The top of the laser welding equipment 11 is equipped with a dust suction pipe 14. The right side of the dust suction pipe 14 passes through the moving block 204 and is connected to a conical suction nozzle 15. The rear side of the top of the operating table 1 is fixedly connected to an L-shaped lamp post 16. The left side of the L-shaped lamp post 16 is fixedly connected to a lighting lamp 17.

The lighting lamp 17 can provide additional lighting to facilitate the inspection of incomplete welding.

Specifically, the anti-slip groove 18 can improve the anti-slip ability of the clamping block 7, the limiting groove 19 can limit the position of the rotor, the warning sign block 21 can remind the operator to pay attention to safety, the protective cylinder 22 can prevent small impurities from flying out and injuring the operator during rotation welding, and the ultrasonic scanning device 23 can scan the welded rotor to determine whether the welding is complete.

[0030] Working Principle: Before using the device, firstly, the rotor to be processed is placed on top of the grooved disc 8. Then, the servo motor 3 is started, driving the bevel gear 4 to rotate. The meshing transmission between bevel gear 4 and bevel gear 5 causes bevel gear 5 to rotate, which in turn causes the threaded rod 6 to rotate. The clamping block 7 on the outside of the threaded rod 6 moves towards the center of the grooved disc 8. When the clamping block 7 is in complete contact with the rotor, the continued rotation of the threaded rod 6 will prevent the clamping block 7 from moving further, thus stopping the threaded rod 6 and bevel gear 5. Then, the continued rotation of bevel gear 4 will cause the entire grooved disc 8 to rotate. At the same time, the cylinder 9 is started, driving the L-shaped plate 10 to move vertically to adjust... The height of the laser welding equipment 11 is adjusted to achieve precise welding of different parts of the rotor. During rotor welding, the moving mechanism 2 first adjusts the moving block 204 to the appropriate position, then the fixing knob 206 is rotated to ensure its position is fixed. Subsequently, the motor 201 is started, and the gear 202 rotates accordingly. The meshing transmission between the gear 202 and the rack 203 allows the laser welding equipment 11 to move horizontally. During the rotor rotation, the roller 205 contacts it to ensure that the laser welding equipment 11 maintains a constant distance from the rotor surface, thereby ensuring that the output energy of the laser welding equipment 11 to the welding point remains consistent, and ensuring that the welding effect of the welding point is uniform.
