Description

Technical Field

[0001] The invention relates to the technical field of motor rotor processing equipment, in particular to a variable frequency motor scattered-piece rotor core riveting tool. Background Art

[0002] The riveting tooling for the loose-piece rotor core is used to fix the loose pieces in the slots of the rotor core, usually by riveting. This tooling usually includes a fixture, a mold and a pressure system to ensure that the loose pieces are correctly installed on the rotor core; Fixture design: The fixture needs to be able to firmly clamp the rotor core for subsequent riveting operations. The design of the fixture should take into account the shape and size of the rotor core to ensure that the fixture can firmly fix the core. Die design: The mold is used to support and position the loose pieces so that they remain in the correct position during riveting. The design of the mold needs to match the shape of the loose pieces to ensure that the loose pieces can be correctly installed on the rotor core. Pressure system: Riveting requires a certain amount of pressure to ensure a good connection between the loose pieces and the core. Therefore, the riveting tooling needs to include a controllable pressure system to ensure that appropriate pressure is applied during the riveting process.

[0003] However, when processing the rotor core, multiple rivets need to be inserted, but due to the limitations of the holes in the core rotor, the staff needs to manually adjust the position of the core. In actual work, it will consume a lot of manpower and material resources and the processing efficiency is low. In response to the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a variable frequency motor scattered rotor core riveting tool, including a positioning mechanism, the positioning mechanism also includes a fixed bracket, the top of the fixed bracket is fixedly connected to a support rod, and the bottom of the fixed bracket is fixedly connected to a hydraulic box;

[0006] The steering mechanism comprises an equipment base fixedly connected to the bottom of the hydraulic box, and the top of the equipment base is rotatably connected to a rotating gear.

[0007] Preferably, the positioning mechanism also includes an oil outlet box connected to the side wall of the hydraulic box, the top of the support rod is fixedly connected to an electric telescopic rod, the inner wall of the hydraulic box is slidably connected to a sealing slide, and the top of the sealing slide is fixedly connected to an L-shaped rod.

[0008] Preferably, the positioning mechanism also includes a fixing ring fixedly connected to the side wall of the fixing bracket, a rotating disk is rotatably connected to the inner wall of the fixing ring, a positioning block is fixedly connected to the top of the rotating disk, a rotor core is placed on the outer wall of the positioning block, and a rubber block is rotatably connected to the side wall of the fixing bracket.

[0009] Preferably, the riveting mechanism also includes a riveting rod fixedly connected to the bottom of the electric telescopic rod, the outer wall of the riveting rod is slidably connected to the inner wall of the limiting cylinder, the side wall of the limiting cylinder is connected with a feed pipe, and a plurality of rivet strips are placed on the inner wall of the feed pipe, the rotor core to be processed is placed on the top of the rotating disk, and the rotor core is ensured to be in the center of the rotating disk by limiting the positioning block and the protrusions on the surface of the rotating disk, and the power of the electric telescopic rod is turned on. As the electric telescopic rod contracts regularly and moves downward, the riveting rod moves downward synchronously under pressure, and pushes the rivet strip inside the limiting cylinder to move downward synchronously, so that the rivet strip breaks through the limitation of the limiting assembly at the bottom of the limiting cylinder and enters the riveting hole of the rotor core to complete the riveting process of the equipment, and the riveting rod moves upward along the inner wall of the limiting cylinder by using the force of the electric telescopic rod to reset and move upward. When the riveting rod reaches the top, the lowest position of the riveting rod will exceed the output port of the feed pipe, and the rivet strip staying inside the feed pipe will enter the limiting cylinder and enter the state to be processed.

[0010] Preferably, the riveting mechanism also includes a sliding groove opened on the inner wall of the limiting cylinder, the inner wall of the sliding groove is rotatably connected with a control gear, the inner wall of the sliding groove is slidably connected with a limiting slide plate, the side wall of the limiting slide plate is meshingly connected with the side wall of the control gear, the inner wall of the sliding groove is slidably connected with a shielding plate, the side wall of the shielding plate is meshingly connected with the side wall of the control gear, the inner wall of the through hole of the limiting slide plate is slidably connected with a limiting slide plate, the side wall of the limiting slide plate is fixedly connected with a spring, and when the inside of the rotor core is completely filled, it will appear as follows Figure 2 In the state shown, after the last rivet bar is inserted into the rotor core, the rotor core rotates due to the rotation of the rotating disk, but at this time the first rivet bar contacts the outer wall of the limit rotating plate, restricting the rotor core from continuing to rotate, thereby preventing the rivet bar from damaging the outer wall of the rotor core while the equipment is still in operation after completing the processing.

[0011] Preferably, the riveting mechanism also includes a material blocking groove opened on the side wall of the limiting cylinder, a center positioning rod is rotatably connected to the inner wall of the material blocking groove, a return spring is fixedly connected to the inner wall of the center positioning rod, a plurality of obstruction plates are fixedly connected to the side wall of the limiting cylinder, and a limited rotating plate is rotatably connected to the side wall of the limiting cylinder. In order to solve the problem that the rivet strip may tilt after entering the interior of the rivet strip, a plurality of center positioning rods are arranged inside the equipment, and a plurality of center positioning rods are affected by the return spring inside thereof and will tilt toward the center position, presenting a Figure 4In the state shown, when the rivet strip enters the interior of the limiting cylinder, the rivet strip is affected by its own weight and moves downward through the inner wall of the limiting cylinder. During this process, the port of the rivet strip faces downward, and the top of the rivet strip is relatively large. During the falling process, the port of the rivet strip will contact the inclined surface of the center positioning rod and reach the lowest point of the center positioning rod along the inclined surface of the center positioning rod, which is also the center point of the limiting cylinder. This ensures that the rivet strip is located at the center point of the rotor core hole before processing, ensures the orderliness of equipment processing, and reduces the probability of rivet strip jamming.

[0012] Preferably, the steering mechanism also includes a plurality of special-shaped grooves provided on the side wall of the rotating gear, a control rotating plate is rotatably connected to the inner wall of the plurality of special-shaped grooves, and a return spring 2 is fixedly connected to the side wall of the control rotating plate, and one end of the return spring 2 away from the control rotating plate is fixedly connected to the inner wall of the special-shaped groove, and the rivet bar's own weight is utilized, when the rivet bar enters the inner wall of the limiting cylinder, the top of the rivet bar will contact the top of the limiting slider, thereby limiting the falling of the rivet bar, and the force of the limiting slider and the downward movement of the limiting slide plate pushes the baffle plate to move upward through the control gear, so that when there is a rivet bar inside the limiting cylinder, the raw material inside the feed pipe cannot enter the rivet bar, thereby ensuring the linkage of the rivet bar feeding of the equipment.

[0013] Preferably, the steering mechanism also includes a hydraulic telescopic rod connected through the side wall of the oil outlet tank, one end of the hydraulic telescopic rod away from the oil outlet tank is fixedly connected to a pulling plate, and one end of the L-shaped rod away from the sealing slide is fixedly connected to the top of the electric telescopic rod. After completing one processing, the electric telescopic rod regularly moves up and down. When the electric telescopic rod moves down, the sealing slide is controlled to move down synchronously through the L-shaped rod, so that the liquid inside the hydraulic box enters the hydraulic telescopic rod through the oil outlet tank, thereby causing the hydraulic telescopic rod to expand outward. At the same time, the pulling plate contacts the outer wall of the control rotating plate under the push of the hydraulic telescopic rod. When one end of the restricted special-shaped groove is perpendicular to the center of the circle and the other end is an inclined surface, when the pulling plate moves outward, the pulling plate pushes the control rotating plate to rotate. The reset spring 2 accumulates mechanical power in this process, and after the pulling plate is completely away from the control rotating plate, the reset spring 2 releases power to reset the control rotating plate. Figure 8 As shown, after the equipment completes the downward movement and riveting process, the sealing slide moves up and the pulling plate is reset synchronously. However, at this time, the control rotating plate cannot rotate because it is in contact with the vertical surface of the special-shaped groove. Finally, under the pulling force of the pulling plate, the control rotating plate drives the rotating gear to rotate, so that the rotating gear drives the rotating disk and the rotor core at the top to rotate at a certain angle, so that the remaining rotor core hole is aligned with the center point of the riveting mechanism.

[0014] The present invention has the following beneficial effects:

[0015] (1) Before use, the present invention places the rotor core to be processed on the top of the rotating disk, and limits the rotor core at the center of the rotating disk by means of the positioning block and the protrusions on the surface of the rotating disk. The power of the electric telescopic rod is turned on. As the electric telescopic rod contracts regularly and moves downward, the riveting rod moves downward synchronously under pressure, and pushes the rivet strip inside the limiting cylinder to move downward synchronously, so that the rivet strip breaks through the limitation of the limiting assembly at the bottom of the limiting cylinder and enters the riveting hole of the rotor core, completing the riveting process of the equipment. The riveting rod moves upward along the inner wall of the limiting cylinder by means of the resetting upward force of the electric telescopic rod. When the riveting rod reaches the top, the lowest position of the riveting rod will exceed the output port of the feed pipe, and the rivet strip staying inside the feed pipe will enter the limiting cylinder and enter the state to be processed. By using the above components, the preliminary preparation work of the equipment is reduced and the working efficiency of the equipment is improved.

[0016] (2) The present invention aims to solve the problem that the rivet bar may tilt after entering the interior of the rivet bar. A plurality of center positioning rods are arranged inside the device. The plurality of center positioning rods are affected by the internal return springs and tilt toward the center position, showing the following Figure 4 In the state shown, when the rivet strip enters the interior of the limiting cylinder, the rivet strip is affected by its own weight and moves downward through the inner wall of the limiting cylinder. During this process, the port of the rivet strip faces downward, and the top of the rivet strip is relatively large. During the falling process, the port of the rivet strip will contact the inclined surface of the center positioning rod and reach the lowest point of the center positioning rod along the inclined surface of the center positioning rod, which is also the center point of the limiting cylinder. This ensures that the rivet strip is located at the center point of the rotor core hole before processing, ensures the orderliness of equipment processing, and reduces the probability of rivet strip jamming.

[0017] (3) After completing one processing, the present invention utilizes the characteristic that the electric telescopic rod moves up and down regularly. When the electric telescopic rod moves down, the sealing slide plate is controlled to move down synchronously through the L-shaped rod, so that the liquid inside the hydraulic box enters the hydraulic telescopic rod through the oil outlet tank, thereby causing the hydraulic telescopic rod to expand outward. At the same time, the pulling plate contacts the outer wall of the control rotating plate under the push of the hydraulic telescopic rod. When one end of the restricted special-shaped groove is perpendicular to the center of the circle and the other end is an inclined surface, when the pulling plate moves outward, the pulling plate pushes the control rotating plate to rotate. The reset spring 2 accumulates mechanical power in this process. After the pulling plate is completely away from the control rotating plate, the reset spring 2 releases power to reset the control rotating plate. Figure 8As shown, after the equipment moves down to complete the riveting process, the sealing slide moves up and the pulling plate is reset synchronously. However, at this time, the control turn plate cannot rotate because it is in contact with the vertical surface of the special-shaped groove. Finally, under the pull of the resetting force of the pulling plate, the control turn plate drives the rotating gear to rotate, so that the rotating gear drives the rotating disk and the rotor core on the top to rotate at a certain angle, so that the remaining rotor core holes are aligned with the center point of the riveting mechanism. Through the application of the above components, the equipment can be autonomously turned and continuously processed, thereby improving the processing efficiency of the equipment.

[0018] (4) The present invention utilizes the rotor core to be completely filled, and the result will be as follows Figure 2 In the state shown, after the last rivet bar is inserted into the rotor core, the rotor core rotates due to the rotation of the rotating disk, but at this time the first rivet bar contacts the outer wall of the limit turn plate, limiting the rotor core from continuing to rotate, thereby preventing the rivet bar from damaging the outer wall of the rotor core when the equipment is still in operation after the processing is completed; in addition, utilizing the rivet bar's own weight, when the rivet bar enters the inner wall of the limit cylinder, the top of the rivet bar will contact the top of the limit slider, limiting the fall of the rivet bar, and the force of the limit slider and the downward movement of the limit slide plate pushes the baffle plate upward through the control gear, so that when there is a rivet bar inside the limit cylinder, the raw material inside the feed pipe cannot enter the rivet bar, thereby ensuring the linkage of the rivet bar feeding of the equipment.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] For example, see Figure 1 - Figure 3 The present invention is a variable frequency motor scattered rotor core riveting tool, comprising a positioning mechanism 1, the positioning mechanism 1 also includes a fixed bracket 101, the top of the fixed bracket 101 is fixedly connected to a support rod 102, and the bottom of the fixed bracket 101 is fixedly connected to a hydraulic box 103;

[0032] The riveting mechanism 2 includes a fixing frame 201 fixedly connected to the side wall of the support rod 102, an end of the fixing frame 201 away from the support rod 102 is fixedly connected to a mounting frame 202, and a limiting cylinder 203 is fixedly connected to the inner wall of the mounting frame 202;

[0033] The steering mechanism 3 comprises an equipment base 301 fixedly connected to the bottom of the hydraulic box 103 , and a rotating gear 302 is rotatably connected to the top of the equipment base 301 .

[0034] The positioning mechanism 1 also includes an oil outlet box 104 connected to the side wall of the hydraulic box 103, an electric telescopic rod 105 is fixedly connected to the top of the support rod 102, a sealing slide 106 is slidably connected to the inner wall of the hydraulic box 103, and an L-shaped rod 107 is fixedly connected to the top of the sealing slide 106.

[0035] The positioning mechanism 1 also includes a fixing ring 108 fixedly connected to the side wall of the fixing bracket 101, a rotating disk 109 is rotatably connected to the inner wall of the fixing ring 108, a positioning block 110 is fixedly connected to the top of the rotating disk 109, a rotor core 111 is placed on the outer wall of the positioning block 110, and a rubber block 112 is rotatably connected to the side wall of the fixing bracket 101.

[0036] For example 2, please refer to Figure 4 - Figure 8 The present invention is a variable frequency motor scattered rotor core riveting tool. On the basis of Example 1, the riveting mechanism 2 also includes a riveting rod 204 fixedly connected to the bottom of the electric telescopic rod 105. The outer wall of the riveting rod 204 is slidably connected to the inner wall of the limiting cylinder 203. The side wall of the limiting cylinder 203 is connected with a feed pipe 205. A plurality of rivet strips 206 are placed on the inner wall of the feed pipe 205. The rotor core 111 to be processed is placed on the top of the rotating disk 109, and the positioning block 110 and the convex blocks on the surface of the rotating disk 109 are used to limit the rotor core 111 to the center of the rotating disk 109. The power of the electric telescopic rod 105 is turned on. As the electric telescopic rod 105 is turned on, 5 regularly contracts. When the electric telescopic rod 105 moves downward, the riveting rod 204 moves downward synchronously under pressure, and pushes the rivet strip 206 in the limiting tube 203 to move downward synchronously, so that the rivet strip 206 breaks through the limit of the limiting assembly at the bottom of the limiting tube 203 and enters the riveting hole of the rotor core 111, completing the riveting process of the equipment. The riveting rod 204 moves upward along the inner wall of the limiting tube 203 by using the force of the electric telescopic rod 105 to reset and move upward. When the riveting rod 204 reaches the top, the lowest position of the riveting rod 204 will exceed the output port of the feed pipe 205, and the rivet strip 206 staying in the feed pipe 205 will enter the limiting tube 203 and enter the state to be processed.

[0037] The riveting mechanism 2 also includes a sliding groove 207 provided on the inner wall of the limiting cylinder 203, a control gear 208 is rotatably connected to the inner wall of the sliding groove 207, a limiting slide plate 209 is slidably connected to the inner wall of the sliding groove 207, the side wall of the limiting slide plate 209 is meshingly connected to the side wall of the control gear 208, a shielding plate 210 is slidably connected to the inner wall of the sliding groove 207, the side wall of the shielding plate 210 is meshingly connected to the side wall of the control gear 208, a limiting slider 211 is slidably connected to the inner wall of the through hole of the limiting slider 209, and a spring is fixedly connected to the side wall of the limiting slider 211. After the inside of the rotor core 111 is completely filled, it will appear as follows Figure 2 In the state shown, after the last rivet 206 is inserted into the rotor core 111, the rotor core 111 rotates due to the rotation of the rotating disk 109, but at this time the first rivet 206 contacts the outer wall of the limit rotating plate 216, restricting the rotor core 111 from continuing to rotate, thereby preventing the rivet 206 from damaging the outer wall of the rotor core 111 when the equipment is still in operation after the processing is completed.

[0038] The riveting mechanism 2 also includes a material blocking groove 212 opened on the side wall of the limiting cylinder 203, a center positioning rod 213 is rotatably connected to the inner wall of the material blocking groove 212, a return spring 214 is fixedly connected to the inner wall of the center positioning rod 213, a plurality of blocking plates 215 are fixedly connected to the side wall of the limiting cylinder 203, and a limited rotating plate 216 is rotatably connected to the side wall of the limiting cylinder 203. In view of the problem that the rivet strip 206 may tilt after entering the inside of the rivet strip 206, a plurality of center positioning rods 213 are arranged inside the device, and a plurality of center positioning rods 213 are affected by the return spring 214 inside thereof and will tilt toward the center position, presenting a Figure 4 In the state shown, after the rivet strip 206 enters the interior of the limiting cylinder 203, the rivet strip 206 is affected by its own weight and moves downward through the inner wall of the limiting cylinder 203. During this process, the end of the rivet strip 206 faces downward, and the top of the rivet strip 206 is larger. During the falling process, the end of the rivet strip 206 will contact the inclined surface of the center positioning rod 213 and reach the lowest point of the center positioning rod 213 along the inclined surface of the center positioning rod 213, which is also the center point of the limiting cylinder 203. This ensures that the rivet strip 206 is located at the center point of the hole in the rotor core 111 before processing, ensures the orderliness of equipment processing, and reduces the probability of the rivet strip 206 getting stuck.

[0039] The steering mechanism 3 also includes a plurality of special-shaped grooves 303 provided on the side wall of the rotating gear 302, and a control rotating plate 304 is rotatably connected to the inner wall of the plurality of special-shaped grooves 303, and a return spring 2 305 is fixedly connected to the side wall of the control rotating plate 304, and one end of the return spring 205 away from the control rotating plate 304 is fixedly connected to the inner wall of the special-shaped groove 303. By utilizing the weight of the rivet strip 206 itself, when the rivet strip 206 enters the inner wall of the limiting cylinder 203, the top of the rivet strip 206 will contact the top of the limiting slider 211 to limit the falling of the rivet strip 206, and the downward force of the limiting slider 211 and the limiting slide plate 209 pushes the baffle plate 210 to move upward through the control gear 208, so that when there is a rivet strip 206 inside the limiting cylinder 203, the raw material inside the feed pipe 205 cannot enter the rivet strip 206, thereby ensuring the linkage of the feeding of the equipment rivet strip 206.

[0040] The steering mechanism 3 also includes a hydraulic telescopic rod 306 connected to the side wall of the oil outlet tank 104. The end of the hydraulic telescopic rod 306 away from the oil outlet tank 104 is fixedly connected to the pulling plate 307. The end of the L-shaped rod 107 away from the sealing slide 106 is fixedly connected to the top of the electric telescopic rod 105. After completing a processing, the electric telescopic rod 105 moves up and down regularly. When the electric telescopic rod 105 moves down, the sealing slide 106 is controlled to move down synchronously through the L-shaped rod 107, so that the liquid inside the hydraulic box 103 enters the oil outlet tank 104 through the oil outlet tank 104. The hydraulic telescopic rod 306 is inside, so that the hydraulic telescopic rod 306 expands outward, and at the same time, the pulling plate 307 contacts the outer wall of the control rotating plate 304 under the push of the hydraulic telescopic rod 306. When one end of the restricted special-shaped groove 303 is perpendicular to the center of the circle and the other end is an inclined surface, when the pulling plate 307 moves outward, the pulling plate 307 pushes the control rotating plate 304 to rotate. The reset spring 2 305 accumulates mechanical power in this process, and after the pulling plate 307 is completely away from the control rotating plate 304, the reset spring 2 305 releases power to reset the control rotating plate 304. Figure 8 As shown, after the equipment completes the downward movement and riveting process, the sealing slide plate 106 moves up and the pulling plate 307 is reset synchronously, but at this time, the control rotating plate 304 is in contact with the vertical surface of the special-shaped groove 303, and the control rotating plate 304 cannot rotate. Finally, under the pulling of the reset force of the pulling plate 307, the control rotating plate 304 drives the rotating gear 302 to rotate, so that the rotating gear 302 drives the rotating disk 109 and the top rotor core 111 to rotate at a certain angle, so that the remaining holes of the rotor core 111 are aligned with the center point of the riveting mechanism 2.

[0041] A specific application of this embodiment is as follows: before use, the present invention places the rotor core 111 to be processed on the top of the rotating disk 109, and through the positioning block 110 and the limit of the protrusion on the surface of the rotating disk 109, ensure that the rotor core 111 is in the center of the rotating disk 109, turn on the power of the electric telescopic rod 105, and as the electric telescopic rod 105 contracts regularly, when the electric telescopic rod 105 moves down, the riveting rod 204 moves down synchronously under pressure, and pushes the rivet strip 206 in the limiting cylinder 203 to move down synchronously, so that the rivet strip 206 breaks through the limit of the limiting assembly at the bottom of the limiting cylinder 203 and enters the riveting hole of the rotor core 111, completing the riveting of the equipment. The pressing process is carried out, and the upward force of the electric telescopic rod 105 is used to reset the rivet pressing rod 204. The rivet pressing rod 204 moves upward along the inner wall of the limiting cylinder 203. When the rivet pressing rod 204 reaches the top, the lowest position of the rivet pressing rod 204 will exceed the output port of the feed pipe 205, and the rivet strip 206 staying inside the feed pipe 205 will enter the limiting cylinder 203 and enter the state to be processed. After the rivet strip 206 enters the inside of the rivet strip 206, there may be a problem of the rivet strip 206 tilting. A plurality of center positioning rods 213 are arranged inside the equipment, and a plurality of center positioning rods 213 are affected by the reset springs 214 inside them, and will tilt toward the center position, showing a state as follows: Figure 4 In the state shown, after the rivet strip 206 enters the interior of the limiting cylinder 203, the rivet strip 206 is affected by its own weight and moves downward through the inner wall of the limiting cylinder 203. During this process, the end of the rivet strip 206 faces downward, and the top of the rivet strip 206 is larger. During the falling process, the end of the rivet strip 206 will contact the inclined surface of the center positioning rod 213 and reach the lowest point of the center positioning rod 213 along the inclined surface of the center positioning rod 213, which is also the center point of the limiting cylinder 203. This ensures that the rivet strip 206 is located at the center point of the hole in the rotor core 111 before processing, ensures the orderliness of the equipment processing, reduces the probability of the rivet strip 206 getting stuck, and after completing one processing, the electric telescopic rod 105 is used to move up and down regularly. The characteristic is that when the electric telescopic rod 105 moves downward, the sealing slide plate 106 is controlled to move downward synchronously through the L-shaped rod 107, so that the liquid inside the hydraulic box 103 enters the hydraulic telescopic rod 306 through the oil outlet tank 104, so that the hydraulic telescopic rod 306 expands outward, and at the same time, the pulling plate 307 contacts the outer wall of the control rotating plate 304 under the push of the hydraulic telescopic rod 306. When one end of the restricted special-shaped groove 303 is perpendicular to the center of the circle and the other end is an inclined surface, when the pulling plate 307 moves outward, the pulling plate 307 pushes the control rotating plate 304 to rotate, and the reset spring 2 305 accumulates mechanical power in this process, and after the pulling plate 307 is completely away from the control rotating plate 304, the reset spring 2 305 releases power to reset the control rotating plate 304. Figure 8As shown, after the equipment has completed the downward movement and riveting process, the sealing slide plate 106 moves up and the pulling plate 307 is reset synchronously. However, at this time, the control rotating plate 304 is in contact with the vertical surface of the special-shaped groove 303, and the control rotating plate 304 cannot rotate. Finally, under the pulling of the reset force of the pulling plate 307, the control rotating plate 304 drives the rotating gear 302 to rotate, so that the rotating gear 302 drives the rotating disk 109 and the top rotor core 111 to rotate at a certain angle, so that the remaining holes of the rotor core 111 are aligned with the center point of the riveting mechanism 2. Through the application of the above components, the autonomous steering and continuous processing of the equipment are realized, and the processing efficiency of the equipment is improved. After the inside of the rotor core 111 is completely filled, it will appear as follows Figure 2 In the state shown, after the last rivet bar 206 is inserted into the rotor core 111, the rotor core 111 rotates due to the rotation of the rotating disk 109, but at this time the first rivet bar 206 contacts the outer wall of the limiting rotating plate 216, limiting the rotor core 111 from continuing to rotate, thereby preventing the rivet bar 206 from damaging the outer wall of the rotor core 111 when the equipment is still in operation after the processing is completed; in addition, by utilizing the weight of the rivet bar 206 itself, when the rivet bar 206 enters the inner wall of the limiting cylinder 203, the top of the rivet bar 206 will contact the top of the limiting slider 211, limiting the falling of the rivet bar 206, and the downward force of the limiting slider 211 and the limiting slide plate 209 pushes the baffle plate 210 to move upward through the control gear 208, so that when there is a rivet bar 206 inside the limiting cylinder 203, the raw material inside the feeding pipe 205 cannot enter the rivet bar 206, thereby ensuring the linkage of the rivet bar 206 feeding of the equipment.
