Technical Field

[0001] The invention relates to the technical field of stator core welding equipment, in particular to a block-type stator core circular welding machine and a welding method thereof. Background Art

[0002] The stator core is an important component in the motor, which is used to provide a magnetic circuit so that the motor can generate a magnetic field and convert electrical energy into mechanical energy. Usually, the stator core is made of many insulated silicon steel sheets stacked together to reduce the hysteresis and eddy current losses of the core. The circular layout can make better use of space and is particularly suitable for some application scenarios with limited space. The circular structure helps to reduce mechanical vibration and noise, improve the running smoothness and comfort of the motor, and the optimized circular layout may help reduce the magnetic resistance of the magnetic circuit and improve the efficiency and performance of the motor.

[0003] Among them, before welding the stator core, several cores need to be assembled into a circle. Most of the above processes are done manually and with the use of templates to correct the position of the cores to ensure that the assembled shape is a perfect circle. However, the manual filling method is time-consuming and labor-intensive, and the work efficiency is low. In response to the above problems, the following solutions are proposed. Summary of the invention

[0006] The welding discharging mechanism comprises a welding column fixedly connected to the top of the mounting plate, a plurality of laser welding devices are fixedly connected to the inner wall of the welding column, and a discharging track is fixedly connected to the top of the welding column.

[0007] Preferably, the positioning and clamping mechanism also includes a plurality of sliding grooves provided on the side walls of the control box, a roller is rotatably connected to the inner wall of the sliding groove, a plurality of control pull straps are fixedly connected to the side wall of the tightening wheel, an output shaft is fixedly connected to the bottom of the tightening wheel, a power motor is fixedly connected to the end of the output shaft away from the tightening wheel, an equipment base is fixedly connected to the outer wall of the power motor, and a plurality of sliding power output frames are fixedly connected to the top of the equipment base.

[0008] Preferably, the positioning clamping mechanism also includes a U-shaped rod slidably connected to the inner wall of the sliding power output frame, a rotating plate is rotatably connected to the side wall of the U-shaped rod, an end of the U-shaped rod away from the rotating plate is fixedly connected to a pushing plate, the end of the control pull belt away from the tightening wheel is fixedly connected to the side wall of the rotating plate, and a pushing spring is fixedly connected to the side wall of the U-shaped rod.

[0009] Preferably, the auxiliary feeding mechanism also includes a stator core placed on the inner wall of the feeding pipe, a buffer leather pad is fixedly connected to the top of the mounting plate, and a plurality of limit slide grooves are opened on the top of the mounting plate. During the rotation process of the tightening wheel, the control belts on the outer wall of the tightening wheel are subjected to equal rotation angles. A U-shaped rod and a pushing plate are arranged inside the equipment. When the equipment completes the filling, the power supply of the power motor is turned on, and the output shaft tightens the control belts around through the tightening wheel, and the plurality of control belts drive the rotating plate at the other end and the U-shaped rod to move synchronously, so that the U-shaped rod moves along the inner wall of the sliding power frame toward the center of the equipment. At this time, the pushing plate will push the stator core placed on the top of the mounting plate to move synchronously toward the center point of the equipment, and the plurality of stator cores will be affected by the thrust and will move synchronously to the center point of the equipment, and when the stator cores contact each other, they will form equal perfect circles required for welding.

[0010] Preferably, the auxiliary feeding mechanism also includes a baffle plate slidably connected to the inner wall of the limiting slide groove, a push rod is fixedly connected to the side wall of the U-shaped rod, and an inclined block is fixedly connected to the end of the push rod away from the U-shaped rod. When the U-shaped rod is controlled to pull the pull belt toward the center position, the push spring will accumulate mechanical power. When the equipment is positioned and clamped, as the U-shaped rod moves inward, the top of the U-shaped rod will block the bottom outlet of the feed pipe. Figure 4 As shown, after the equipment completes welding, as the push spring releases the accumulated mechanical power, it will force the U-shaped rod to spread around the equipment. When the U-shaped rod moves to the outermost edge, the top of the U-shaped rod will lose the restriction on the feed pipe, and the stator core placed inside the feed pipe will fall on the top of the buffer pad, and the buffer pad will absorb most of the vibration force of the equipment falling.

When the equipment completes welding, the U-shaped rod drives the pushing rod to move outward along the inner wall of the baffle plate. When the equipment is welded and positioned, the baffle plate is limited by the outer wall of the pushing rod and will move downward along the inner wall of the limiting slide groove so that the top of the baffle plate and the mounting plate are in a horizontal position. When the equipment starts the feeding process, the inclined surface block is driven by the outward movement of the pushing rod, passes through the inner wall of the baffle plate, and completely passes through the baffle plate, releasing the restriction on the baffle plate. At this time, the baffle plate is limited by the internal spring and moves upward, and forms a baffle on the top of the equipment mounting plate to prevent the top stator core from tilting when it falls, causing the equipment to get stuck, thereby reducing the probability of errors in the equipment.

[0012] Preferably, the welding discharging mechanism also includes a control push plate fixedly connected to the top of the electric telescopic rod, a plurality of sliding rods are fixedly connected to the outer wall of the control push plate, a roller 2 is rotatably connected to the inner wall of the through hole of the sliding square plate, a pulling belt is fixedly connected to the outer wall of the sliding rod, and the end of the pulling belt away from the sliding rod is fixedly connected to the outer wall of the tilting plate. After the welding is completed by using the stator core, the product forms a complete whole. A power connection block and a sliding power output frame are arranged inside the equipment. When the U-shaped rod moves to the outermost periphery, the power connection block contacts the side wall of the sliding power output frame to connect the power of the electric telescopic rod. Source, at this time the electric telescopic rod generates an upward extension force, the sliding rod rises synchronously, and the sliding rod is slidably connected to the sliding square plate. When the sliding rod moves up, the sliding rod forces one end of the tilting plate to rotate downward by pulling the belt. At this time, the tilting plate close to the end of the sliding rod rotates downward, and the end with the rubber block fixed will tilt upward. Several rubber blocks will contact the inner wall of the perfect circular product. The high friction of the rubber blocks and the outward extrusion force will drive the entire processed product to move upward along the outer wall of the discharging track to complete the discharging of the equipment, reduce manual participation, and improve the accuracy and efficiency of the equipment.

[0013] A block-type stator core circular welding machine and a welding method thereof, comprising the following steps:

[0014] S1: The present invention turns on the power supply of the power motor, and the output shaft tightens the surrounding control belts through the tightening wheel, and a plurality of control belts drive the rotating plate at the other end and the U-shaped rod to move synchronously, so that the U-shaped rod moves toward the center of the device along the inner wall of the sliding power output frame;

[0015] S2: The push plate will push the stator core placed on the top of the mounting plate to move synchronously toward the center point of the device, and several stator cores will be synchronously moved to the center point of the device under the influence of the thrust, and when the stator cores contact each other, they will form an equal perfect circle required for welding;

[0016] S3: When the U-shaped rod is controlled to tighten the pull belt toward the center position, the push spring will accumulate mechanical power. When the equipment is positioned and clamped, as the U-shaped rod moves inward, the top of the U-shaped rod will block the bottom outlet of the feed pipe.

[0017] The present invention has the following beneficial effects:

[0018] (1) The present invention utilizes the characteristic that when the tightening wheel is rotating, each control belt on the outer wall of the tightening wheel is subjected to the same rotation angle. A U-shaped rod and a pushing plate are arranged inside the equipment. When the equipment is filled, the power supply of the power motor is turned on, and the output shaft tightens the control belts around it through the tightening wheel, and several control belts drive the rotating plate and the U-shaped rod at the other end to move synchronously, so that the U-shaped rod moves along the inner wall of the sliding power frame toward the center of the equipment. At this time, the pushing plate will push the stator core placed on the top of the mounting plate to move synchronously toward the center point of the equipment, and several stator cores will be affected by the thrust and will move synchronously to the center point of the equipment. When the stator cores contact each other, they will form a perfect circle required for welding. Through the application of the above components, it is ensured that the stator core will form a perfect circle around the equipment before welding.

[0019] (2) The present invention utilizes the U-shaped rod to control the tension belt to be tightened toward the center position, and the push spring will accumulate mechanical power. When the device is positioned and clamped, as the U-shaped rod moves inward, the top of the U-shaped rod will block the bottom outlet of the feed pipe, such as Figure 4 As shown, after the equipment completes welding, as the push spring releases the accumulated mechanical power, it will force the U-shaped rod to spread around the equipment. When the U-shaped rod moves to the outermost edge, the top of the U-shaped rod will lose the restriction on the feed pipe, and the stator core placed inside the feed pipe will fall on the top of the buffer pad, and the buffer pad will absorb most of the vibration force of the equipment falling. The stator core that has completed feeding is pushed by the U-shaped rod to form a perfect circle on the outer wall of the welding column. The equipment welds the inner wall of the stator core through a laser welding device. Through the application of the above components, the equipment can realize autonomous feeding and improve the welding efficiency of the equipment.

[0020] (3) The present invention utilizes the characteristic that after the stator core is welded, the product forms a complete whole. A power connection block and a sliding power output frame are arranged inside the equipment. When the U-shaped rod moves to the outermost periphery, the power connection block contacts the side wall of the sliding power output frame and connects the power of the electric telescopic rod. At this time, the electric telescopic rod generates an upward extension force, and the sliding rod rises synchronously. The sliding rod and the sliding square plate are slidably connected. When the sliding rod moves upward, the sliding rod forces one end of the tilting plate to rotate downward by pulling the belt. At this time, the tilting plate close to the end of the sliding rod rotates downward, and the end fixed with the rubber block will tilt upward. Several rubber blocks will contact the inner wall of the circular product. The high friction of the rubber block and the outward extrusion force will drive the processed overall product to move upward along the outer wall of the discharge track to complete the discharge of the equipment, reduce manual participation, and improve the accuracy and efficiency of the equipment.

[0021] (4) When the equipment of the present invention completes welding, the U-shaped rod drives the push rod to move outward along the inner wall of the baffle plate. When the equipment is welded and positioned, the baffle plate is restricted by the outer wall of the push rod and moves downward along the inner wall of the limiting slide groove, so that the top of the baffle plate is in a horizontal position with the mounting plate. When the equipment starts the feeding process, the inclined block is driven outward by the push rod, passes through the inner wall of the baffle plate, and completely passes through the baffle plate, thereby releasing the restriction on the baffle plate. At this time, the baffle plate is restricted by the internal spring and moves upward, and forms a baffle on the top of the equipment mounting plate to prevent the top stator core from tilting when it falls and causing the internal jam of the equipment, thereby reducing the probability of errors in the equipment.

When the equipment is positioned and clamped, as the U-shaped rod 111 moves inward, the top of the U-shaped rod 111 will block the bottom outlet of the feed pipe 203.

[0049] A specific application of this embodiment is: when the U-shaped rod 111 is controlled by the pull belt 106 to be tightened toward the center position, the push spring 113 will accumulate mechanical power. When the device is positioned and clamped, as the U-shaped rod 111 moves inward, the top of the U-shaped rod 111 will block the bottom outlet of the feed pipe 203, such as Figure 4As shown, after the equipment completes welding, as the push spring 113 releases the accumulated mechanical power, it will force the U-shaped rod 111 to spread around the equipment. When the U-shaped rod 111 moves outward to the outermost edge, the top of the U-shaped rod 111 will lose the restriction on the feed pipe 203, and the stator core 204 placed inside the feed pipe 203 will fall on the top of the buffer pad 205, and the buffer pad 205 will absorb most of the vibration force of the equipment falling. The stator core 204 that has completed the feeding is pushed by the U-shaped rod 111 to form a perfect circle on the outer wall of the welding column 301. The equipment welds the inner wall of the stator core 204 through the laser welding device 302. When the tightening wheel 103 is in the rotation process, the control straps 106 on the outer wall of the tightening wheel 103 are In order to achieve the characteristic of equal rotation angle, a U-shaped rod 111 and a push plate 114 are provided inside the equipment. When the equipment completes filling, the power supply of the power motor 108 is turned on, and the output shaft 107 tightens the surrounding control straps 106 through the tightening wheel 103, and several control straps 106 drive the rotating plate 112 at the other end and the U-shaped rod 111 to move synchronously, so that the U-shaped rod 111 moves toward the center of the equipment along the inner wall of the sliding power rack 110. At this time, the push plate 114 will push the stator core 204 placed on the top of the mounting plate 101 to move synchronously toward the center point of the equipment, and several stator cores 204 will be affected by the thrust and will be synchronously moved to the center point of the equipment, and when the stator cores 204 contact each other, they will form equal perfect circles required for welding. By applying the above components, it is ensured that before the equipment is welded, the stator core will be surrounded to form a perfect circle. After the stator core 204 is welded, the product forms a complete whole. A power connection block 312 and a sliding power output frame 110 are arranged inside the equipment. When the U-shaped rod 111 moves to the outermost periphery, the power connection block 312 contacts the side wall of the sliding power output frame 110, and the power of the electric telescopic rod 304 is turned on.

The high friction of the rubber blocks 307 and the outward extrusion force will drive the processed product to move upward along the outer wall of the discharge track 303 to complete the discharge of the equipment. When the equipment completes welding, the U-shaped rod 111 drives the push rod 208 to move outward along the inner wall of the baffle plate 207. When the equipment is welded and positioned, the baffle plate 207 is restricted by the outer wall of the push rod 208 and will move downward along the inner wall of the limiting slide 206, so that the top of the baffle plate 207 is in a horizontal position with the mounting plate 101. When the equipment starts the feeding process, the inclined block 209 is driven outward by the push rod 208.Passing through the inner wall of the baffle plate 207 and completely passing through the baffle plate 207, the restriction on the baffle plate 207 is released. At this time, the baffle plate 207 is restricted by the internal spring and moves upward, and forms a baffle on the top of the equipment installation plate 101 to prevent the top stator core 204 from tilting when it falls, causing the internal jam of the equipment, and reducing the probability of equipment errors.
