Description

Technical Field

[0001] The invention relates to the field of wire embedding devices, in particular to an automatic wire embedding device for a three-phase asynchronous motor. Background Art

[0002] The stator production of three-phase asynchronous motors requires a coil embedding machine, which is a stator processing equipment that embeds the motor core into the coil. It quickly pushes the wire coated with wire insulation glue into the stator through mechanical means, so that the wire is embedded in the stator.

[0003] When the wire is pushed into the stator, it will collide with the stator and bend. The wire is easily scratched and damaged by the stator during the collision and bending process, causing the insulation wrapped around the outside of the wire to fall off, affecting the performance of the wire. Summary of the invention

[0004] The present application provides an automatic wire embedding device for a three-phase asynchronous motor. Before the wire is pushed into a stator, a guide tube is used to guide and deform the wire, thereby reducing collision and bending between the wire and the stator, thereby protecting the wire.

[0005] The present application provides a three-phase asynchronous motor automatic wire embedding device adopts the following technical solution:

[0006] A three-phase asynchronous motor automatic wire embedding device, comprising a machine body, a wire embedding column arranged on the machine body, two rotating rods rotatably connected to the machine body, a mounting rod arranged on the rotating rod, and a limit plate connected to the mounting rod and used for pressing the stator against the wire embedding column, the machine body is slidably connected with two sliders, the two sliders are relatively arranged on both sides of the wire embedding column, the sliders are slidably connected with a fixing frame along the length direction of the wire embedding column, the fixing frame is provided with an arc-shaped soft sleeve 1 on a surface facing the wire embedding column, and a ring groove is provided on a surface of the soft sleeve 1 away from the fixing frame, and the machine body is provided with a first driving component for controlling the sliding of the slider The two first driving components drive the two sliders to slide so that the two soft sleeves are connected to each other and wrap the ends of the stators. The two soft sleeves are connected to each other to form a guide tube. The two annular grooves will enclose to form a wrapping cavity when the two soft sleeves are connected. The inner diameter of the wrapping cavity is larger than the inner diameter of the guide tube. The wrapped end of the stator is located in the wrapping cavity. The wire will collide with and bend with the guide tube during the process of being pushed into the stator. The machine body is also provided with a second driving component for driving the fixed frame to slide. The second driving component drives the fixed frame to slide so that the guide tube pushes the stator with completed wire embedding out of the wire embedding column.

[0007] By adopting the above technical solution, when the wire is pushed into the stator, the wire will pass through the guide tube, collide with the guide tube and bend and deform. The guide tube is soft and not easy to damage the wire when it collides with the wire. Bending and deforming the wire in advance can reduce the collision and bending between the wire and the stator, thereby protecting the wire. After the stator is embedded, the second drive component drives the two fixed frames to slide so that the two fixed frames slide with the guide tube, allowing the guide tube to push the stator out of the wire embedding column, completing the automatic material removal of the stator.

[0008] Preferably, the first driving assembly includes a push-pull rod provided on the limiting plate and a matching groove provided on the slider, the push-pull rod extends into the matching groove, and when the mounting rod moves, the push-pull rod drives the slider to move.

[0009] By adopting the above technical solution, the limit plate can drive the slider to slide together through the push-pull rod during the rotation process.

[0010] Preferably, the sliding block is provided with a first sliding groove, and the fixed frame is slidably connected in the first sliding groove, and the second driving component includes a pressure block arranged on the push-pull rod, a first spring arranged in the first sliding groove, and an inclined surface arranged on the fixed frame, and the elastic force of the first spring acts on the fixed frame to drive the fixed frame to move out of the first sliding groove, and when the machine body is not started, the push-pull rod and the side of the matching groove away from the wire embedding column are in conflict, and a movable space is left between the push-pull rod and the side of the matching groove close to the wire embedding column, and the inclined surface is located on the movement path of the pressure block, and the pressure block will press the inclined surface when moving, thereby driving the fixed frame to slide into the first sliding groove, and when the fixed frame slides into the first sliding groove, it will press the first spring so that the first spring is compressed.

[0011] By adopting the above technical solution, when the push-pull rod moves toward the wire embedding column, the pressing block will squeeze the inclined surface to drive the fixed frame to slide into the first slide slot, so that the two soft sleeves move to the predetermined position and finally connect with each other and wrap the end of the stator, and at the same time, the two first springs can be compressed to store elastic potential energy. After the stator is embedded, the elastic potential energy of the two springs is used to drive the two fixed frames to slide out of the first slide slot, so that the guide tube pushes the stator out of the wire embedding column to complete the automatic material removal of the stator.

[0012] Preferably, a second slide groove is provided on the fixed frame, a stop block is slidably connected in the second slide groove, an avoidance groove for the stop block to extend into is provided on the soft sleeve, the avoidance groove is located on the side of the annular groove close to the body, and a third driving mechanism for driving the stop block to slide is also provided on the fixed frame, and the third driving mechanism drives the stop block to slide into the avoidance groove.

[0013] By adopting the above technical solution, the guide tube may be deformed when pushing the stator because it is not hard, so the guide tube cannot push the stator out of the wire embedding column well. Therefore, a stop block is provided. After the stator is embedded, the third driving unit drives the stop block to slide into the avoidance groove, so that the stop block assists the guide tube to push the stator together. When the stop block pushes the stator, the soft sleeve will play a buffering and protective effect between the stop block and the stator.

[0014] Preferably, the third driving mechanism includes a first rack and a second rack slidably connected in the second slide slot, a first gear rotatably connected in the second slide slot, and a second spring arranged in the second slide slot, the first rack and the second rack are both meshed with the first gear, the first rack is connected to the stop block, the elastic force of the second spring acts on the second rack, the second spring always drives the second rack to move toward the push-pull rod, and in the initial state, one end of the second rack extends out of the fixed frame and is located on the movement path of the push-pull rod, and the stop block extends into the avoidance groove, and when the push-pull rod moves close to the wire embedding column, it will collide with the second rack and push the second rack into the second slide slot to make the stop block move into the second slide slot.

[0015] By adopting the above technical solution, when the machine body is not started, the stopper extends into the avoidance groove. When the push-pull rod moves close to the wire embedding column, the second rack will be pushed into the second slide groove, and finally the stopper will move into the second slide groove, preventing the wire from colliding with the stopper when it is pushed into the stator, thereby protecting the wire. After the stator is embedded, the push-pull rod moves away from the wire embedding column, and the second spring pushes the second rack out of the second slide groove. When the second rack slides, it pushes the first rack to move through the first gear, so that the stopper moves into the avoidance groove to prepare for pushing the stator.

[0017] By adopting the above technical solution, before the stator is pushed out of the wire embedding column, the third driving component drives the rod body to slide out of the third sliding groove to allow the receiving platform to move closer to the wire embedding column, so that the receiving platform can receive the stator pushed out of the wire embedding column. After the stator is pushed onto the receiving platform, the third driving component drives the rod body to slide into the third sliding groove, so that the receiving platform moves away from the wire embedding column, making room for the technicians to operate and facilitating the technicians to place the new stator on the wire embedding column.

[0018] Preferably, the third driving assembly includes a screw rod rotatably connected to the mounting seat, and a driving part for driving the screw rod to rotate, and the sliding block is threadedly connected to the screw rod.

[0019] By adopting the above technical solution, the sliding of the rod body 1 can be controlled by controlling the forward and reverse rotation of the screw rod through the driving unit, thereby controlling the up and down movement of the receiving platform.

[0020] Preferably, the end of the screw rod extends out of the mounting seat, the axis of the screw rod intersects with the axis of one of the rotating rods, the driving part includes a second gear and rack three provided on the end of the screw rod, the rack three is connected to the push-pull rod through a rod, the second gear is located on the movement path of rack three, the rack three meshes with the second gear when moving and drives the second gear to rotate, and the rack three meshes with bevel gear three after the stator is pushed out of the wire embedding column.

[0021] By adopting the above technical solution, when the installation rod rotates close to the wire embedding column, the rod drives the rack three to move so that the rack three moves close to the bevel gear three. After the push rod pushes the slider to move, the rack three moves to mesh with the second gear and pushes the second gear to rotate. When the second gear rotates, it drives the screw rod one to rotate. The screw rod one will drive the rod body one to move away from the third slide slot, so that the receiving platform moves close to the end of the wire embedding column away from the machine body, which is convenient for receiving the stator. The subsequent machine body drives the rotating rod to rotate, and the rotating rod rotation will drive the installation rod to rotate. In this process, the stator is first pushed onto the receiving platform. When the installation rod moves and resets by pulling the slider through the push-pull rod, the rack three will move and reset to mesh with the second gear and drive the second gear to rotate, so that the screw rod rotates. The screw rod rotation will drive the rod body one to move into the third slide slot, so that the receiving platform moves away from the end of the wire embedding column away from the machine body, leaving operating space for the technicians, so that the technicians can put the new stator on the wire embedding column.

DETAILED DESCRIPTION

[0043] The present invention is further described in detail below in conjunction with the accompanying drawings to make the technical solution of the present application easier to understand and grasp.

[0044] Reference Figure 1 The present embodiment of the invention is a three-phase asynchronous motor automatic wire-inserting device, which includes a machine body 1, a wire-inserting column 11 fixed on the machine body 1, two rotating rods 12 rotatably connected to the machine body 1, mounting rods 13 respectively fixed to the two rotating rods 12, and two stopper plates 14 respectively connected to the two mounting rods 13 and used to press the stator 9 against the wire-inserting column 11. The axes of the two rotating rods 12 are parallel to the axes of the wire-inserting column 11, and the machine body 1 can drive the two rotating rods 12 to rotate.

[0045] Reference Figure 1 and Figure 2 Two sliders 2 are slidably connected to the body 1, and the two sliders 2 are arranged on both sides of the wire embedding column 11. The two sliders 2 slide around the two rotating rods 12 respectively. A first driving component 5 for controlling the sliding of the slider 2 is provided on the body 1. The first driving component 5 includes a push-pull rod 51 fixed on the mounting rod 13 and a matching groove 52 provided on the slider 2. The push-pull rod 51 extends into the matching groove 52. When the mounting rod 13 moves, the push-pull rod 51 drives the slider 2 to move. When the body 1 is not started, the push-pull rod 51 and the side of the matching groove 52 away from the wire embedding column 11 conflict with each other, and there is a movable space between the push-pull rod 51 and the side of the matching groove 52 close to the wire embedding column 11.

[0046] Reference Figure 1-Figure 3 , Figure 10-12The slider 2 is provided with a first slide groove 21, and a fixing frame 3 is slidably connected in the first slide groove 21 along the length direction of the wire embedding column 11. An arc-shaped soft sleeve 31 is fixed on the side of the fixing frame 3 facing the wire embedding column 11, and an annular groove 311 is provided on the side of the soft sleeve 31 away from the fixing frame 3. After the stator 9 is placed on the wire embedding column 11, the body 1 is started to let the push-pull rod 51 push the two sliders 2 to slide closer, and finally the two soft sleeves 31 are connected to each other and wrap the end of the stator 9. The two soft sleeves 31 are connected to each other to form a guide tube 41. The two annular grooves 311 will enclose and form a wrapping cavity 42 when the two soft sleeves 31 are connected. The inner diameter of the wrapping cavity 42 is larger than the inner diameter of the guide tube 41, and the wrapped end of the stator 9 is located in the wrapping cavity 42. When the stator 9 is wired, the push rod on the body 1 first pushes the wire on the wire-inserting column 11 into the guide tube 41 so that the wire collides with the guide tube 41 and is bent. Then, the bent wire passes through the guide tube 41 and is pushed into the stator 9.

[0047] Reference Figure 1-Figure 4 The machine body 1 is also provided with a second driving assembly 6 for driving the fixed frame 3 to slide. The second driving assembly 6 drives the fixed frame 3 to slide so that the guide tube 41 pushes the wire-embedded stator 9 out of the wire-embedded column 11. The second driving assembly 6 includes a pressing block 61 fixed on the push-pull rod 51, a first spring 62 placed in the first slide groove 21, and an inclined surface 63 provided on the fixed frame 3. The elastic force of the first spring 62 acts on the fixed frame 3 to drive the fixed frame 3 to move out of the first slide groove 21. The inclined surface 63 is located on the movement path of the pressing block 61. When the pressing block 61 moves, it presses against the inclined surface 63 to drive the fixed frame 3 to slide into the first slide groove 21. When the fixed frame 3 slides into the first slide groove 21, it presses against the first spring 62 so that the first spring 62 is compressed.

[0048] Reference Figure 1-Figure 4 A second slide groove 32 is provided on the fixing frame 3, and a stop block 33 is slidably connected in the second slide groove 32 along the axial direction perpendicular to the wire embedding column 11. An avoidance groove 312 for the stop block 33 to extend into is provided on the soft sleeve 31, and the avoidance groove 312 is located on the side of the annular groove 311 close to the body 1. A second driving component 6 for driving the stop block 33 to slide is also provided on the fixing frame 3. The second driving component 6 drives the stop block 33 to slide into the avoidance groove 312, and the stop block 33 is located in the avoidance groove 312 when the body 1 is not started.

[0049] Reference Figure 1-Figure 4The third driving assembly 7 includes a first rack 71 and a second rack 72 which are slidably connected to the second slide groove 32 along the axis direction perpendicular to the wire embedding column 11, a first gear 73 which is rotatably connected to the second slide groove 32, and a second spring 74 which is placed in the second slide groove 32. The first rack 71 and the second rack 72 are both meshed with the first gear 73. The first rack 71 is connected to the stop block 33. The axis of the first gear 73 is perpendicular to the axis of the wire embedding column 11. The elastic force of the second spring 74 acts on the second rack 72. The second spring 74 is located on the side of the second rack 72 away from the push-pull rod 51. The second spring 74 always drives the second rack 72 to move toward the push-pull rod 51. When the machine body 1 is not started, one end of the second rack 72 extends out of the fixing frame 3 and is located on the movement path of the push-pull rod 51. When the push-pull rod 51 moves close to the wire embedding column 11, it will collide with the second rack 72 and push the second rack 72 into the second slide groove 32 so that the stop block 33 moves into the second slide groove 32.

[0050] Reference Figure 1 and Figure 5 A mounting seat 15 is provided on the machine body 1, and a third slide groove 151 is opened on the mounting seat 15. A sliding block 152 is vertically slidably connected in the third slide groove 151, and a rod body 153 is fixedly connected to the sliding block 152. The top of the rod body 153 extends out of the mounting seat 15 and is connected to a receiving platform 154. The receiving platform 154 is used to receive the stator 9 pushed out of the wire embedding column 11.

[0051] Reference Figure 1 and Figure 5 The machine body 1 is also provided with a third driving assembly 8 for driving the rod body 153 to slide. The third driving assembly 8 includes a screw rod 81 rotatably connected to the mounting seat 15, and a driving part 82 for driving the screw rod 81 to rotate. The screw rod 81 extends into the third sliding groove 151, and the rod body 153 is threadedly connected to the screw rod 81. One end of the screw rod 81 away from the receiving platform 154 extends out of the mounting seat 15, and the axis of the screw rod 81 intersects with the axis of one of the rotating rods 12. The driving part 82 includes a second gear 821 and a rack three 822 coaxially fixed on the end of the screw rod 81 away from the receiving platform 154. The rack three 822 is connected to the mounting rod 13 through a rod. The second gear 821 is located on the movement path of the rack three 822. The rack three 822 meshes with the second gear 821 when moving and drives the second gear 821 to rotate. The rack three 822 meshes with the second gear 821 after the stator 9 is pushed out of the wire embedding column 11.

[0052] The specific wire embedding steps of the automatic wire embedding device for a three-phase asynchronous motor in this application are as follows:

[0053] Reference Figure 1-Figure 4 , Figure 6-Figure 8First, the technician puts the stator 9 on the wire embedding column 11, and then starts the machine body 1. After the machine body 1 is started, it will drive the two rotating rods 12 to rotate. When the two rotating rods 12 rotate, they will drive the two mounting rods 13, the two limiting plates 14, and the two push-pull rods 51 toward the wire embedding column 11. When the two push-pull rods 51 move, they will move with the pressing block 61. When the push-pull rods 51 move close to the matching groove 52 and close to the side of the wire embedding column 11, the pressing block 61 will conflict with the inclined surface 63, and the pressing block 61 will drive the fixing frame 3 to move into the first sliding groove 21 and compress the first spring 62.

[0054] Reference Figure 1-Figure 4 , Figure 6-Figure 8 At the same time, when the push-pull rod 51 moves close to the matching groove 52 and close to the side of the wire embedding column 11, the push-pull rod 51 will collide with the second rack 72 and push the second rack 72 into the second slide groove 32. When the second rack 72 enters the second slide groove 32, it will press the second spring 74 to compress the second spring 74. When the second rack 72 moves into the second slide groove 32, it will drive the first rack 71 and the block 33 to move out of the avoidance groove 312 and enter the second slide groove 32 through the first gear 73.

[0055] Reference Figure 1-Figure 4 , Figure 6-Figure 8 Finally, when the push-pull rod 51 moves to contact the side of the matching groove 52 close to the wire embedding column 11, the second rack 72 stops moving, the stop block 33 is also completely located in the second slide groove 32, the pressure block 61 stops pressing the fixed frame 3, and the fixed frame 3 stops sliding.

[0056] Reference Figure 1 , Figure 5 , Fig. 9 , and then the push-pull rod 51 will follow the movement of the installation rod 13 and push the slider 2 to slide so that the slider 2 moves closer to the wire embedding column 11. In the process of the push-pull rod 51 pushing the slider 2 to slide closer to the wire embedding column 11, the rack three 822 will move to mesh with the second gear 821 and push the second gear 821 to rotate. When the second gear 821 rotates, it will drive the screw rod 81 to rotate. When the screw rod 81 rotates, it will drive the sliding block 152 and the rod body 1 153 to move toward the wire embedding column 11, so that the receiving platform 154 moves closer to the end of the wire embedding column 11 away from the machine body 1, and then as the rack three 822 continues to move, the rack three 822 will move away from the second gear 821.

[0057] Reference Figure 10-12 Finally, when the mounting rod 13 stops moving, the two sliders 2 also stop moving. At this time, the two soft sleeves 31 are connected to each other and wrap the end of the stator 9. The two soft sleeves 31 are connected to each other to form a guide tube 41. The two limit plates 14 press the stator 9 against the wire embedding column 11. Then the push rod on the body 1 will push the wire placed on the wire embedding column 11 into the stator 9 to complete the wire embedding work of the stator 9.

[0058] Reference Fig.13 , Fig.14 After the stator 9 is wire-embedded, the machine body 1 drives the two rotating rods 12, the two mounting rods 13, the two limiting plates 14, and the two push-pull rods 51 to move and reset. During the movement and reset of the two push-pull rods 51, the two pressing blocks 61 will move away from the two inclined surfaces 63, and the two pressing blocks 61 will not press the fixing frame 3. However, the two limiting plates 14 will still press the stator 9 against the wire-embedded column 11, and the stator 9 will limit the sliding of the two fixing frames 3.

[0059] Reference Fig.13 , Fig.14 In the process that the two limit plates 14 gradually move away from each other and no longer press the stator 9, the push-pull rod 51 gradually stops pressing the second rack 72. At this time, the second spring 74 will rebound and drive the second rack 72 to move out of the second slide groove 32. When the second rack 72 moves out of the second slide groove 32, it will drive the first rack 71 to slide toward the soft sleeve 31 through the first gear 73, so that the block 33 moves into the avoidance groove 312 to prepare for pushing the stator 9.

[0060] Reference Figure 13-Figure 16 , and then when the two limit plates 14 move to no longer press the stator 9, the pressing block 61 has moved to the outside of the sliding path of the inclined surface 63. Once the limit plates 14 no longer press the stator 9, the two first springs 62 will rebound and reset and push the two fixing frames 3 to move out of the first sliding groove 21, allowing the two fixing frames 3 to move toward the receiving platform 154. When the two fixing frames 3 slide, they will drive the guide tube 41 and the two pressing blocks 33 to push the stator 9 out of the wire embedding column 11, so that the stator 9 falls onto the receiving platform 154, completing the automatic material removal of the stator 9.

[0061] Reference Fig.15 , and then when the push-pull rod 51 moves to the side that contacts the mating groove 52 away from the wire embedding column 11, the push-pull rod 51 will pull the slider 2 to move and reset, so that the two fixing frames 3 and the soft sleeve 1 31 move and reset together. When the installation rod 13 pulls the slider 2 to move and reset through the push-pull rod 51, the rack 3 822 will move and reset to mesh with the second gear 821 and drive the second gear 821 to rotate, so that the screw rod 81 rotates, and the rotation of the screw rod 81 will drive the rod body 153 to move into the third slide groove 151, so that the receiving platform 154 moves away from the end of the wire embedding column 11 away from the machine body 1, leaving operating space for the technicians, so that it is convenient for the technicians to put the new stator 9 on the wire embedding column 11.

[0062] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
