Description

Technical Field

[0001] This utility model relates to the field of winding machines, and in particular to an automatic adjustment device for the spacing between winding dies in a winding machine. Background Technology

[0002] A winding machine is an automated device used to wind wires onto a bobbin or magnetic core according to a specific pattern. It is widely used in the production of electromagnetic components such as motors, transformers, and inductors. Stator with different stack heights requires copper wires of different lengths. This requires the winding machine to adjust the die spacing between the front and rear dies of the winding die to a suitable distance for the product before winding.

[0003] When adjusting the die spacing of a current winding machine, the machine must first be stopped. Then, a worker takes a ratchet wrench, enters the machine, aligns it with the hexagonal part, and starts turning the screw. Through the threaded engagement, the winding die moves outward or inward, thus changing the spacing between the front and rear winding dies. When the correct die spacing is achieved, the operator leaves the machine and then restarts it. The current adjustment method requires the worker to enter the machine, posing a safety risk, and also requires stopping the machine and manual operation, which is time-consuming and labor-intensive.

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.

[0046] This utility model provides, for example Figures 1-5 The automatic adjustment device for the spacing of winding dies in a winding machine, as shown, includes a mounting frame 1, a front winding die 2, a rear winding die 3, a moving mechanism 4, and a driving mechanism 5. The mounting frame 1 is used to mount the front winding die 2 and the rear winding die 3.

The moving mechanism 4 is mounted on the mounting frame 1 and is used to drive the rear winding die 3 to move horizontally.

The driving mechanism 5 is located at the other end of the mounting frame 1 and is used to drive the moving mechanism 4 to move, thereby facilitating the adjustment of the spacing between the front winding die 2 and the rear winding die 3.

[0047] Furthermore, the moving mechanism 4 includes a fixed base 41, the lower surface of which is fixedly connected to the upper surfaces of the front winding die 2 and the rear winding die 3, and the fixed base 41 is used to connect the front winding die 2, the rear winding die 3 and the lead screw 43; a sliding groove, which is formed at the bottom of the mounting frame 1, and the inner cavity of the sliding groove is slidably inserted into the fixed base 41, and the sliding groove is used to accommodate the fixed base 41, and the fixed base 41 moves in the inner cavity of the sliding groove; and a mounting base 42, the upper surface of which is fixedly connected to the mounting frame 1.

The two ends of the lead screw 43 are provided with reverse threads. By rotating the lead screw 43, the two fixed seats 41 move in opposite directions along the two ends of the lead screw 43, which drives the front winding die 2 and the rear winding die 3 to move in opposite directions, thereby adjusting the distance between the front winding die 2 and the rear winding die 3.

[0048] Specifically, the drive mechanism 5 includes a gear 51, which is fixedly connected to one end of the lead screw 43 and rotates with the lead screw 43, serving to limit and fix the lead screw 43; a coupling follower 52, one end of which is fixedly connected to one end of the gear 51, and the end of the coupling follower 52 is serrated, used to drive the lead screw 43 to rotate; and a limiting block 53, which is located at one end of the mounting bracket 1, above the gear 51, and is L-shaped with a tooth-like protrusion at the bottom, which is inserted between the teeth of the gear 51 to limit and fix the gear 51 and the lead screw 43. The top surface of the limiting block 53 is inclined. A mounting shaft is included, with one end fixedly connected to the outer wall of one end of the mounting frame 1, and the other end rotatably connected to the limiting block 53. The mounting shaft is positioned at the corner of the limiting block 53, rotatably connecting the limiting block 53 to the mounting frame 1, allowing the limiting block 53 to rotate around the mounting shaft. A fixing plate 54 is located on one side of the mounting frame 1. A connecting plate 55 has its upper surface fixedly connected to the lower surface of one end of the fixing plate 54, with two connecting plates 55 located on both sides of the fixing plate 54. A guide fixing seat 56 has its upper surface fixedly connected to the lower surface of the connecting plate 55, and the guide fixing seat 56 is used to mount the driven shaft 510. A motor mounting plate 57 is also included. A motor mounting plate 57 is fixedly connected to one side of a connecting plate 55, and is fixed between two connecting plates 55 for fixing and mounting a servo motor 59; a main pulley 58 is located on one side of the motor mounting plate 57 and is used to drive the driven pulley 511 to rotate; a servo motor 59 is fixedly mounted between the connecting plates 55, and the output end of the servo motor 59 is connected to the main pulley 58 for transmission. The servo motor 59 is electrically connected to an external power supply through an external first switch, and the operation of the servo motor 59 drives the main pulley 58 to rotate; a driven shaft 510 is rotatably connected to a guide fixing seat 56 and is used for mounting... Driven pulley 511; Driven pulley 511 is fixedly installed at one end of driven shaft 510 and is used to drive screw 43 to rotate; Drive belt 512 is disposed between main pulley 58 and driven pulley 511, and main pulley 58 and driven pulley 511 are connected by drive belt 512, so that main pulley 58 drives driven pulley 511 to rotate together; Cylinder 513 is fixedly installed on one side of the outer wall of guide fixing seat 56, and cylinder 513 is electrically connected to an external power supply through an external second switch. As cylinder 513 runs, it drives push block 514 to move in the horizontal direction;The push block 514 has one side of its outer wall connected to the output end of the cylinder 513. The push block 514 is L-shaped and is used to push the limit block 53 to rotate. The cylinder 513 drives one end of the push block 514 to move towards the limit block 53, causing the limit block 53 to rotate counterclockwise around the mounting shaft. The protrusion at the bottom of the limit block 53 separates from the teeth of the gear 51, releasing the connection between the gear 51 and the lead screw 43. Limiting: When the pushing block 514 moves away from the limiting block 53, the weight of the limiting block 53 causes it to rotate clockwise. The protrusion is inserted between the teeth of the gear 51, limiting and fixing the gear 51 and the lead screw 43 so that they cannot rotate, thus ensuring the stability of the front winding mold 2 and the rear winding mold 3. Movable rod 515: One end of the movable rod 515 is rotatably connected to the bottom of the pushing block 514, and the other end of the movable rod 515 is slidably inserted into the middle of the driven shaft 510. The movable rod 515 is used to install the coupling active member 516, driving the coupling active member 516 to move and rotate. The movable rod 515 moves horizontally together with the push block 514. The coupling active member 516 is fixedly connected to one end of the movable rod 515, and the position of the coupling active member 516 corresponds to that of the coupling driven member 52. One end of the coupling active member 516 is serrated. By coupling the serrations at one end of the coupling active member 516 with the serrations at one end of the coupling driven member 52, the movable rod 515 drives the lead screw 43 to rotate. Through the operation of the cylinder 513, the push block 514 is driven to move towards the limit block 53. The push block 514 drives the movable rod 515 to move together. One end of the push block 514 presses against the limit block 53, causing the limit block 53 to rotate around... When the mounting shaft rotates counterclockwise, the protrusion at the bottom of the limiting block 53 separates from the teeth of the gear 51, releasing the limiting effect on the gear 51 and the lead screw 43. At this time, the coupling driving member 516 is coupled to one end of the coupling driven member 52, connecting the movable rod 515 and the lead screw 43. Then, the servo motor 59 drives the main pulley 58 to rotate, and the transmission belt 512 drives the driven pulley 511 and the driven shaft 510 to rotate together. The driven shaft 510 drives the movable rod 515 and the lead screw 43 to rotate, causing the two fixed seats 41 to move in opposite directions along both ends of the lead screw 43, driving the front winding die 2 and the rear winding die 3 to move in opposite directions, adjusting the distance between the front winding die 2 and the rear winding die 3. The die spacing can be automatically adjusted without manual intervention inside the device, greatly reducing labor costs and safety risks.

[0049] The other end of the movable rod 515 is cylindrical, which facilitates the rotatable connection between the movable rod 515 and the push block 514. The other end is square. The driven shaft 510 has a movable groove in the middle, which is square. The other end of the movable rod 515 is inserted into the inner cavity of the movable groove. The movable rod 515 is connected to the driven shaft 510, so that the driven shaft 510 drives the movable rod 515 to rotate together. A groove is opened on one side of the upper surface of the mounting bracket 1, and one end of the push block 514 is inserted into the inner cavity of the groove.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
