Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, specifically a straight stator pin-type winding machine. Background Technology

[0002] Winding machines are widely used in the electrical manufacturing industry. For example, they can be used to wind inductors into various motors, transformers, and inductor coils.

[0003] A straight stator is a type of iron core that is strip-shaped before winding. Compared with conventional round stators, this design can significantly reduce the difficulty of winding and improve the slot fill factor. Winding traditional round stators is quite difficult and can easily lead to copper wire waste and low production efficiency. However, by using a straight stator, the wire can be bent and shaped into a cylindrical shape after winding, thus solving these problems. During the motor manufacturing process, the winding machine is responsible for winding the insulated copper wire onto the straight stator in a specific way.

[0004] When using a winding machine to wind copper wire onto a straight stator, a clamp is usually required to fix the straight stator. Although there are various clamps available on the market for round stators to meet the needs of fixing round stators of different diameters, clamps for straight stators may be more specialized in design. Many clamps can only match straight stators of a specific size. Therefore, a pin-type winding machine for straight stators is proposed. Utility Model Content

[0027] 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.

[0028] Please see Figure 1-7 A straight stator pin-type winding machine is provided, which has a worktable 1, a vertical plate 2 is provided on the top of the worktable 1, a longitudinal and transverse movement adjustment mechanism 3 is provided at the bottom of the vertical plate 2, a clamping mechanism 4 is provided on the front side of the longitudinal and transverse movement adjustment mechanism 3, and the front of the clamping mechanism 4 is used to clamp the straight stator 5. A winding device 6 is provided on the top of the worktable 1, and a moving support mechanism 7 is provided on the bottom of the worktable 1.

[0029] like Figure 4 and Figure 5As shown, the clamping mechanism 4 includes a fixed plate 401. A mounting box 402 is fixedly installed on the top of the fixed plate 401. A horizontal main control rod 403 is rotatably installed inside the mounting box 402. One end of the main control rod 403 extends out of the mounting box 402 and is provided with a knob. First bevel gears 404 are fixedly installed near both ends of the main control rod 403. Vertical double-acting screws 406 are rotatably provided on the inner sides of both ends of the fixed plate 401. The thread directions of the upper and lower parts of the double-acting screws 406 are opposite. The upper end of the double-acting screws 406 enters the mounting box 402 and is provided with second bevel gears 405. The two first bevel gears 404 mesh with the second bevel gears 405 at both ends. Two threaded sleeves 407 are threaded onto each bidirectional lead screw 406. The two threaded sleeves 407 are respectively connected to the threads on the upper and lower parts of the bidirectional lead screw 406. Two horizontal positioning strips 408 are provided on the front of the fixing plate 401. The two positioning strips 408 are parallel to each other, and the two ends of the positioning strips 408 are respectively fixedly connected to the corresponding threaded sleeves 407.

[0030] During use, when adjusting the two positioning bars 408, first turn the knob to drive the main control rod 403 to rotate. The main control rod 403 drives the two first bevel gears 404 on it to rotate. The two first bevel gears 404 drive the second bevel gears 405 meshing with them to rotate. The two second bevel gears 405 drive the two bidirectional lead screws 406 to rotate, thereby causing the two lead sleeves 407 to drive the two positioning bars 408 to move in opposite directions. The two fixed length bars 51 fix the top and bottom of the straight bar stator 5 respectively.

[0031] To improve the stability of the main control lever 403 during rotation, a support ring is fixedly installed between the inner top wall and the inner bottom wall of the mounting box 402.

[0032] like Figure 4 and Figure 6 As shown, each of the two positioning bars 408 includes a fixed length bar 51 and two extension bars 52. The two ends of the fixed length bar 51 are fixedly connected to the corresponding threaded sleeves 407. The left and right ends of the two fixed length bars 51 are respectively inserted with extension bars 52. Two conventional spring pins 8 are provided on the opposite side of the two fixed length bars 51. The spring pins 8 are used to lock the position of the corresponding extension bars 52.

[0033] Specifically, when it is necessary to fix straight stators 5 of different lengths, firstly, four extension bars 52 are pulled outward from the inside of the fixed length bar 51. The extension bars 52 have an L-shaped structure, and the four extension bars 52 are respectively pressed against the four corners of the straight stator 5 to achieve fixation.

[0034] During the adjustment of the extension bar 52, the baffle 802 is pulled up, the second spring 803 is in a compressed state, and the inner end of the limiting rod 801 exits the limiting hole 804 of the extension bar 52. At this time, the extension bar 52 can be adjusted. After it is adjusted to the point where another limiting hole 804 corresponds to the limiting rod 801 (multiple limiting holes 804 are provided on the extension bar 52 along its length direction), the baffle 802 is released to release the elastic force of the second spring 803. The expansion of the second spring 803 drives the limiting rod 801 to quickly insert into the corresponding limiting hole 804, relocking the fixed length bar 51 so that the fixed length bar 51 cannot move.

[0035] like Figure 1 and 7 As shown, movable support mechanisms 7 are respectively provided on both sides of the workbench 1. Each movable support mechanism 7 includes a support frame 701, a hydraulic cylinder 702, a connecting block 703, a first spring 704, and a support plate 705. Casters for support on the ground are provided under the support frame 701. The hydraulic cylinder 702 is vertically positioned at the upper end of the support frame 701. The connecting block 703 is located at the lower end of the piston rod of the hydraulic cylinder 702. The support plate 705 is located on the side of the connecting block 703. The first spring 704 is located between the connecting block 703 and the bottom of the support frame 701. The lower side of the workbench 1 is supported on the support plate 705 and is fixedly connected to it. Vertically downward-pointing support legs are provided under the workbench 1.

[0036] During use, when the winding machine needs to be moved to another location, the two hydraulic cylinders 702 first drive the two connecting blocks 703 to slide upwards. The two connecting blocks 703 then drive the two support plates 705 to move upwards, causing the legs under the workbench 1 to separate from the ground. At this point, the winding machine can be easily moved to another location via the casters. After reaching the destination, the two hydraulic cylinders 702 extend, driving the two support plates 705 to move downwards, so that the legs under the workbench 1 contact the ground for support. It is convenient and flexible to use and can also be used for the transfer of other equipment.

[0037] like Figure 1 and Figure 2As shown, the longitudinal and lateral movement adjustment mechanism 3 includes a longitudinal movement device 301 and a lateral movement device 302. The longitudinal movement device 301 includes a longitudinal movement box 31, an electric push rod 32, and a guide rod 33. The electric push rod 32 is vertically mounted downwards on the upper end of the upright plate 2. The middle part of the longitudinal movement box 31 is connected to the lower end of the electric push rod 32. The electric push rod 32 drives the longitudinal movement box 31 to move longitudinally. Vertical guide rods 33 are respectively provided at both ends of the upper part of the longitudinal movement box 31. The guide rods 33 are fitted into the sliding holes at the upper end of the upright plate 2. A third spring is provided between the upper end of the guide rod 33 and the upper part of the upright plate 2. The third spring is sleeved on the guide rod 33. The longitudinal movement of the longitudinal movement box 31 is more stable through the sliding connection between the guide rod 33 and the sliding hole. The lateral moving device 302 includes a motor 41, a threaded rod 42, and a movable seat 43. The front end of the movable seat 43 is fixedly connected to the back of the fixed plate 401. The movable seat 43 is slidably disposed within the longitudinal moving box 31, allowing it to slide laterally within the longitudinal moving box 31. The threaded rod 42 is rotatably disposed within the longitudinal moving box 31, and is in a lateral state. The movable seat 43 is threadedly connected to the threaded rod 42 through a threaded hole. The motor 41 is located on one side of the longitudinal moving box 31, and its output shaft is connected to the threaded rod 42. During use, the motor 41 drives the threaded rod 42 to rotate, thereby causing the movable seat 43 to move laterally, which in turn drives the clamping mechanism 4 to move laterally as a whole. During winding, the longitudinal and lateral moving adjustment mechanism 3 drives the straight bar stator 5 on the clamping mechanism 4 to move up, down, left, and right, cooperating with the winding device 6 to perform the winding operation.

[0038] Specifically, at the start of winding, the longitudinal movable device 301 first adjusts the straight stator 5 to an appropriate starting height. As the winding device 6 starts, the copper wire begins to wind around the straight stator 5. At this time, the motor 41 of the transverse movable device 302 starts and drives the moving seat 43 through the threaded rod 42, so that the straight stator 5 moves at a uniform speed along the axial direction. This, combined with the winding speed of the winding device 6, ensures that the copper wire is wound evenly. When it is necessary to change layers or change the winding mode, the longitudinal movable device 301 will readjust the height of the straight stator 5, while the transverse movable device 302 will adjust the position of the moving seat 43. Throughout the process, the longitudinal and transverse moving adjustment mechanism 3 and the winding device 6 work together to perform the winding operation.

[0039] In summary, this straight stator pin winding machine, by setting up a clamping mechanism 4, enables the two positioning bars 408 to move relative to each other. The position between the two positioning bars 408 changes according to the different heights of the straight stator 5, so that the two fixed-length bars 51 fix the upper and lower sides of the straight stator 5. At the same time, the length of the two positioning bars 408 is adjustable. According to the length of the straight stator 5, the two extension bars 52 are pulled out to fix the left and right sides of the straight stator 5, meeting the fixing requirements of different sizes.

[0040] Furthermore, by setting up the movable support mechanism 7, the winding machine can be easily lifted and moved to the required position. Moreover, the movable support mechanism 7 can be used independently, not only to move the winding machine, but also to move other equipment.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
