Description

Technical Field

[0001] This utility model belongs to the field of transformer winding wheel placement technology, specifically relating to a winding wheel placement rack. Background Technology

[0002] A transformer winding wheel is a device specifically used for winding coils during the transformer manufacturing process. It is mainly used to evenly wind copper wire or other conductors onto a frame to form the coil required by the transformer. When using a winding wheel, a special winding wheel holder is usually used.

[0003] Existing winding wheel placement frames typically consist of a frame and a rotating roller. Installation is completed simply by inserting the winding wheel onto the rotating roller. However, during the winding process, when the winding wheel stops rotating, it may continue to rotate due to inertial kinetic energy, which can lead to loose copper wire or even uneven winding. In addition, the winding wheel may also rotate in the opposite direction, which can easily cause the copper wire to break due to pulling. Utility Model Content

[0004] In view of this, the present invention provides a winding wheel placement rack, which can dissipate inertial kinetic energy when the winding wheel stops rotating through a damping adjustment component, preventing it from rotating too much. This avoids copper wire loosening caused by excessive rotation of the winding wheel and also suppresses copper wire pulling and breaking caused by reverse rotation.

[0005] To solve the above-mentioned technical problems, this utility model provides a winding reel placement frame, including a frame and a placement mechanism disposed on its upper end. The upper end of the frame is provided with a damping adjustment component for adjusting the rotation damping coefficient of the placement mechanism. The damping adjustment component includes a sliding cavity disposed on the upper end of the frame, a sliding frame slidably connected in the sliding cavity, a damping pad disposed at the lower end of the sliding frame, the damping pad contacting the placement mechanism, a threaded rod threadedly connected at the upper end of the frame near the sliding cavity, and a spring disposed at the bottom of the inner cavity of the sliding frame, the upper end of the spring contacting the threaded rod. Even when the winding reel stops rotating, it can dissipate inertial kinetic energy and prevent it from rotating too much. This avoids copper wire loosening caused by excessive rotation of the winding reel and also suppresses copper wire pulling and breaking caused by reverse rotation.

[0006] The placement mechanism includes a placement roller rotatably connected to the frame near the lower end of the sliding cavity. The other end of the placement roller is threadedly connected to a locking threaded sleeve. The outer arc surface of the placement roller near the sliding cavity contacts the lower end of the damping pad. The placement roller is also equipped with a positioning component for positioning the winding wheel, which serves the purpose of placement.

[0007] The positioning assembly includes multiple grooves disposed on the outer arc surface of the placement roller. Each groove is slidably connected to a sliding top plate, and each groove is equipped with an airbag. The airbags contact the top plate located in the same groove, thereby lifting the sliding top plate.

[0008] The positioning assembly also includes an air storage cylinder set inside the placement roller. Multiple air outlets on the end of the air storage cylinder near the locking threaded sleeve are equipped with connecting pipes. The other end of the connecting pipes is connected to the air inlet of the adjacent airbag on the same side. A piston rod is slidably connected to the end of the air storage cylinder away from the air outlet, which serves to inflate the air.

[0009] The positioning assembly also includes springs respectively disposed at both ends of the inner cavity of the slide groove, and the sliding top plate is fixedly connected to the springs located in the same slide groove, thus providing a rebound force.

[0010] The positioning assembly also includes a lead screw rotatably connected to the end of the placement roller away from the locking threaded sleeve. The lead screw is threadedly connected to a corresponding threaded hole on the piston rod, thus providing a driving function.

[0011] The piston rod has a rectangular body, which provides guidance for the piston rod.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] 1. During the winding operation, the operator can adjust the compression of spring one by rotating the threaded rod, so that the damping pad and the outer arc surface of the placement roller form a controllable frictional contact. The preload of spring one and the mechanical locking of the threaded rod together constitute an adjustable damping system, which can dissipate the inertial kinetic energy when the winding wheel stops rotating, and prevent it from rotating too much. This avoids the copper wire loosening caused by the over-rotation of the winding wheel, and also suppresses the copper wire pulling and breaking caused by reverse rotation.

[0014] 2. After the winding wheel sleeve is placed on the placement roller, it is axially fixed by rotating the locking threaded sleeve. Then, the lead screw is rotated. Due to the influence of the threaded connection between the lead screw and the threaded hole, the piston rod is pushed to slide in the air storage cylinder, thereby compressing the air in the air storage cylinder. The gas is injected into the air bag in the slide groove through the connecting pipe, causing the sliding top plate to expand outward to clamp winding wheels of different diameters. When it is necessary to reset, the lead screw is rotated in the opposite direction, and each mechanism is reset. At the same time, the springs at both ends of the slide groove provide elastic reset force for the sliding top plate, causing it to retract into the slide groove. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0021] This embodiment provides a winding reel placement rack, such as Figure 1-4 As shown: The device includes a frame 100 and a placement mechanism disposed on its upper end. The upper end of the frame 100 is provided with a damping adjustment assembly for adjusting the rotational damping coefficient of the placement mechanism. The damping adjustment assembly includes a sliding cavity 300 disposed on the upper end of the frame 100. A sliding frame 301 is slidably connected within the sliding cavity 300. A damping pad 302 is disposed at the lower end of the sliding frame 301, and the damping pad 302 contacts the placement mechanism. A threaded rod 303 is threadedly connected to the upper end of the frame 100 near the sliding cavity 300. The inner cavity of the sliding frame 301... A spring 304 is provided at the bottom, and the upper end of the spring 304 contacts the threaded rod 303. The placement mechanism includes a placement roller 200 rotatably connected to the frame 100 near the lower end of the sliding cavity 300. The other end of the placement roller 200 is threadedly connected to a locking threaded sleeve 201. The outer arc surface of the end of the placement roller 200 near the sliding cavity 300 contacts the lower end of the damping pad 302. The placement roller 200 is also provided with a positioning component for positioning the winding wheel. The end of the placement roller 200 away from the locking threaded sleeve 201 is provided with an annular protrusion.

[0022] During the winding operation, the operator can adjust the compression of the spring 304 by rotating the threaded rod 303, so that the damping pad 302 and the outer arc surface of the placement roller 200 form a controllable frictional contact. The preload of the spring 304 and the mechanical locking of the threaded rod 303 together constitute an adjustable damping system, which can dissipate the inertial kinetic energy when the winding wheel stops rotating, and prevent it from rotating too much. This avoids the copper wire loosening caused by the over-rotation of the winding wheel, and also suppresses the copper wire pulling and breaking caused by reverse rotation.

[0023] like Figure 1-4As shown, the positioning assembly includes multiple grooves disposed on the outer arc surface of the placement roller 200. A sliding top plate 400 is slidably connected in each groove. An airbag 401 is disposed in each groove. The airbags 401 are in contact with the top plate 400 located in the same groove. The positioning assembly also includes an air storage cylinder 402 disposed in the placement roller 200. Multiple air outlets of the air storage cylinder 402 near the locking threaded sleeve 201 are provided with connecting pipes 403. The other end of the connecting pipes 403 is connected to the air inlet of the adjacent airbag 401 on the same side. A piston rod 404 is slidably connected to the end of the air storage cylinder 402 away from the air outlet. The positioning assembly also includes springs 405 disposed at both ends of the inner cavity of the groove. The sliding top plate 400 is fixedly connected to the springs 405 located in the same groove. The positioning assembly also includes a lead screw 406 rotatably connected to the end of the placement roller 200 away from the locking threaded sleeve 201. The lead screw 406 is threadedly connected to the corresponding threaded hole on the piston rod 404.

[0024] After the winding wheel sleeve is placed on the placement roller 200, it is axially fixed by rotating the locking threaded sleeve 201. Then, the lead screw 406 is rotated. Due to the influence of the threaded connection between the lead screw 406 and the threaded hole, the piston rod 404 is pushed to slide in the air storage cylinder 402, thereby compressing the air in the air storage cylinder 402. The gas is injected into the air bag 401 in the slide groove through the connecting pipe 403, causing the sliding top plate 400 to expand outward to clamp winding wheels of different diameters. When it is necessary to reset, the lead screw 406 is rotated in the opposite direction, and each mechanism is reset. At the same time, the springs 405 at both ends of the slide groove provide elastic reset force to the sliding top plate 400, causing it to retract into the slide groove.

[0025] like Figure 2-4 As shown, the piston rod 404 has a rectangular body, which can provide guidance for the piston rod 404.

[0026] The working principle of the winding wheel placement rack provided by this utility model is as follows: During winding operations, the operator can adjust the compression of spring 304 by rotating threaded rod 303, thereby forming a controllable frictional contact between damping pad 302 and the outer arc surface of placement roller 200. The preload of spring 304 and the mechanical locking of threaded rod 303 together constitute an adjustable damping system, which can dissipate inertial kinetic energy when the winding wheel stops rotating, preventing it from rotating too much. This avoids copper wire loosening caused by over-rotation of the winding wheel and also inhibits copper wire pulling and breakage caused by reverse rotation. When the winding wheel is placed on placement roller 200... Then, axial fixation is achieved by rotating the locking threaded sleeve 201. Subsequently, the lead screw 406 is rotated. Due to the influence of the threaded connection between the lead screw 406 and the threaded hole, the piston rod 404 is pushed to slide in the air storage cylinder 402, thereby compressing the air in the air storage cylinder 402. The gas is injected into the air bladder 401 in the slide groove through the connecting pipe 403, causing the sliding top plate 400 to expand outward to clamp the winding wheels of different diameters. When reset is required, the lead screw 406 is rotated in the opposite direction, and each mechanism is reset. At the same time, the springs 405 at both ends of the slide groove provide elastic reset force for the sliding top plate 400, causing it to retract into the slide groove.

[0027] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
