Description

Technical Field

[0001] This utility model relates to the field of coil curing fixture technology, specifically to a fixture suitable for curing coils with multiple magnetic poles. Background Technology

[0002] Magnetic pole coils are important components in motors, generators, or other electromagnetic devices, typically used to generate magnetic fields or achieve electromagnetic induction. The coil material is generally formed by winding copper or aluminum wire, with the number of turns and wire diameter determined according to design requirements. For some large motors, due to special magnetic field or heat dissipation requirements, the coil is usually made of copper busbars. These coils are typically large in size and weight, and special tooling is needed to fix the coil and place the insulating paper before the coil is encapsulated and cured.

[0003] Currently, there are corresponding tooling fixtures for fixing large copper busbar coils of different sizes and specifications. When the specifications of the coil being worked on are changed, the corresponding tooling needs to be changed at the same time, which increases the material change interval. At the same time, multiple sets of tooling fixtures also increase the production costs of enterprises. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A fixture suitable for curing various magnetic pole coils includes a fixed platform. Multiple fixing plates are fixed to the top of the fixed platform in a ring-shaped arrangement. Each fixing plate has an elongated hole, and a fixing buckle is installed at the location of the elongated hole. Holes are also opened at both ends of the fixing plate corresponding to the fixing buckles. The fixing buckles are fixed to the fixed platform using fixing bolts at the two end holes. The fixing plates are clamped to the fixed platform by the fixing buckles. A vertical plate is fixed to one end of each fixing plate, and a baffle is installed on the outer side of the vertical plate away from the fixing plate. The baffle has various specifications with different heights.

[0006] Furthermore, the upright plate has two elongated holes at its four corners, and the baffle plate has fixing holes corresponding to the two elongated holes. The baffle plate and the upright plate are fixed together by fixing bolts at the fixing holes and the two elongated holes. A heat insulation plate is installed on the outer side of the baffle plate away from the upright plate, and multiple through holes are opened in the middle of the heat insulation plate and the baffle plate. The elongated holes facilitate fine-tuning of the baffle plate's fixing position, improving flexibility, and the heat insulation plate can reduce the transfer of heat to the baffle plate and the upright plate during curing.

[0007] Furthermore, a misalignment is pre-set between the baffle and the upright plate. The bottom of the baffle at the misalignment position is inwardly cut, and the top of the upright plate at the misalignment position is inwardly cut. The baffle and the upright plate at the misalignment position are offset and support each other. The misalignment can be used for positioning to ensure that the installation position of the baffle is fixed.

[0008] Furthermore, a fixing block is fixed to the top of the fixing buckle. A movable block is installed on the fixing buckle on the front side of the fixing block facing the upright plate. A hole is opened in the middle of the movable block near the top, and a threaded connecting rod passes through the hole. A notch is opened on the fixing block corresponding to the position of the connecting rod, and the connecting rod is located in the notch. The front end of the connecting rod abuts against the upright plate at the corresponding position. A limiting ball groove is opened on the upright plate corresponding to the position of the connecting rod. A ball is installed in the limiting ball groove, and a protrusion extending out of the limiting ball groove is fixed on the ball. A threaded rod is fixed on the protrusion outside the limiting ball groove. A hole is opened at the front end of the connecting rod, and the threaded rod extends into the hole and is threaded. The thread direction of the threaded rod is opposite to that of the connecting rod. The rotation of the connecting rod can drive the baffle to move, thereby facilitating the adjustment of the baffle position according to the position of the coil.

[0009] Furthermore, the top of the fixing buckle has a pre-set groove corresponding to the position of the movable block, the bottom of the movable block is located in the groove, and the top of the fixing block is designed to protrude towards the top of the movable block. The movable block is limited by the groove and the protruding top of the fixing block. The groove and the protruding top structure of the movable block work together to limit the movement of the movable block.

[0010] Furthermore, a support beam is provided directly above the fixed platform. Multiple uprights (upper one and upper two) are fixed to the bottom of the support beam. Uprights one and two are located within an annular area formed by multiple fixed plates. Each upright has multiple equally spaced insertion holes, through which horizontal bars pass. Pads are placed on the outer side of the baffles corresponding to the annular area on the fixed platform. The horizontal bars separate each ring of copper busbars, facilitating the placement of insulating paper on each ring of copper busbars.

[0011] Furthermore, two uprights are provided, located at the bottom ends of the support beam, and two additional uprights are provided between the two uprights. An opening is formed in the support beam, through which the top of the uprights passes. Multiple equally spaced limiting grooves are formed at the top of the support beam corresponding to the opening. A limiting block is fixed to the top of the uprights, providing limiting support within the limiting grooves. A fixing seat is fixed to the bottom of the uprights, with holes corresponding to the fixing seat on the fixing platform. The fixing platform and the fixing seat are fixed together by bolts. The uprights are movable and can be adjusted according to the position of the copper busbar to ensure balanced support of the copper busbar by the crossbar, preventing the copper busbar from bending.

[0012] Furthermore, lifting lug 1 is fixed at both ends of the top of the support beam, and lifting lug 2 is fixed at the two long sides of the top of the fixed platform. The lifting lugs facilitate lifting, loading, unloading, and movement.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a fixing buckle to fix the fixing plate, and is equipped with an elongated hole and baffles of various height specifications. The position of the baffles can be adjusted to adapt to different specifications of coils. One set of tooling can meet the curing tooling needs of more coils of different specifications, reducing replacement time and reducing enterprise production costs.

[0015] 2. In this utility model, the baffle is moved by the connecting rod, which facilitates the operation and makes the adjustment more precise when adjusting the position of the baffle 7.

[0016] 3. In this utility model, by setting up uprights and horizontal bars, each turn of the copper busbar coil can be supported, which facilitates the placement of each turn of insulating paper.

[0017] 4. In this utility model, by setting the second upright rod to be movable, the position distribution of the horizontal bar can be adjusted according to the specific situation of the copper busbar coil to ensure stable support for the copper busbar coil. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] This application provides a tooling suitable for curing various magnetic pole coils, mainly solving the problems mentioned in the background art, and providing the following technical solutions, which will be discussed below. Figures 1-6 Please provide a detailed explanation:

[0027] A fixture suitable for curing multiple magnetic pole coils includes a fixed platform 1, with multiple fixed plates 2 fixed on the top of the fixed platform 1. The multiple fixed plates 2 are arranged in a ring on the top of the fixed platform 1. The fixed plates 2 have elongated holes 4. Fixing buckles 3 are installed on the fixed plates 2 at the positions of the elongated holes 4. Holes are opened at both ends of the fixed platform 1 corresponding to the positions of the fixing buckles 3. The fixing buckles 3 are fixed to the fixed platform 1 by fixing bolts 5 at the positions of the openings at both ends. The fixed plates 2 are clamped and fixed to the fixed platform 1 by the fixing buckles 3.

[0028] A vertical plate 6 is fixed to one end of the fixed plate 2. The vertical plate 6 has elongated holes 9 at the four corners. A baffle 7 is installed on the outer side of the vertical plate 6 away from the fixed plate 2. The baffle 7 has various specifications with different heights. A fixing hole 8 is opened on the baffle 7 corresponding to the position of the elongated hole 9. The baffle 7 and the vertical plate 6 are fixed together by fixing bolts 10 at the positions of fixing holes 8 and elongated holes 9.

[0029] A support beam 25 is provided directly above the fixed platform 1. Multiple uprights 23 and 24 are fixed at the bottom of the support beam 25. Uprights 23 and 24 are located within an annular area formed by multiple fixed plates 2. Multiple equally spaced insertion holes 27 are provided on uprights 23 and 24. Horizontal bars 28 pass through the insertion holes 27. A pad 33 is placed on the outside of the baffle 7 corresponding to the annular area on the fixed platform 1.

[0030] Before use, adjust the position of the baffle 7 according to the inner diameter and length of the magnetic pole copper busbar coil. When adjusting, first loosen the fixing bolt 5 to relax the fixing force of the fixing buckle 3 on the fixing plate 2. At this time, the fixing plate 2 can be moved within the range of the elongated hole 4 to adjust forward or backward to adjust the position. After the adjustment is completed, tighten the fixing bolt 5 halfway. When using, place and fix the magnetic pole copper busbar one ring at a time. When placing, first place the first ring on the pad 33 outside the ring. At this time, adjust the position of the baffle 7 again so that the baffle 7 is against the inner wall of the copper busbar. Then tighten the fixing bolt 5 to fix it completely.

[0031] The copper busbar coils to be placed are then wrapped around the first upright 23 and the second upright 24, with each wrap separated by a horizontal bar 28. When stacking each wrap, a layer of insulating paper is placed first, and then the horizontal bar 28 at the corresponding position is removed, allowing the copper busbar coil to fall and be stacked. This completes the curing fixture work for the magnetic pole coils. Depending on the height of the coils, baffles 7 of corresponding height specifications are used to adapt to the height. Finally, the magnetic pole coils are sent into the curing equipment for curing.

[0032] In some embodiments, a heat insulation plate 12 is installed on the outer side of the baffle 7 away from the vertical plate 6. The heat insulation plate 12 and the baffle 7 are fixed together by countersunk bolts. Multiple through holes 13 are provided in the middle position of the heat insulation plate 12 and the baffle 7. A misalignment 11 is preset between the baffle 7 and the vertical plate 6. The bottom of the baffle 7 at the misalignment 11 position is incised, and the top of the vertical plate 6 at the misalignment 11 position is incised. The baffle 7 at the misalignment 11 position and the vertical plate 6 are misaligned and support each other.

[0033] The heat insulation board 12 can reduce the heat conduction of the curing colloid to the baffle 7 and the upright plate 6. At the same time, the heat insulation board 12 is made of rubber material to separate the contact between the baffle 7 and the copper busbar, which can prevent the baffle 7 from scratching the insulating paint on the surface of the copper busbar. The structure of the misalignment 11 forms a special misalignment structure, which restricts the baffle 7 to fix the upright plate 6 within a certain range and angle, thereby limiting the installation position and avoiding installation errors.

[0034] In some embodiments, a fixing block 14 is fixed to the top of the fixing buckle 3. A movable block 15 is installed on the fixing buckle 3 facing the front side of the fixing block 14 towards the upright plate 6. A hole is opened in the middle near the top of the movable block 15, and a threaded connecting rod 16 passes through the hole. A notch 17 is opened on the fixing block 14 corresponding to the position of the connecting rod 16. The connecting rod 16 is located in the notch 17, and the front end of the connecting rod 16 abuts against the upright plate 6 at the corresponding position. A limiting ball groove 22 is opened on the upright plate 6 corresponding to the position of the connecting rod 16. A ball ball 19 is installed in the limiting ball groove 22. A protrusion 20 extending out of the limiting ball groove 22 is fixed on the ball ball 19. A threaded rod 21 is fixed on the protrusion 20 outside the limiting ball groove 22. A hole is opened at the front end of the connecting rod 16, and the threaded rod 21 extends into the hole and is threaded. The thread direction of the threaded rod 21 is opposite to the thread direction of the connecting rod 16.

[0035] When adjusting the position of the baffle 7, the connecting rod 16 can be rotated. By utilizing the limiting relationship of the ball bearing 19 within the limiting ball groove 22, the upright plate 6 can be moved, thereby driving the baffle 7 to move and adjust its position. At this time, when fixing the bolt 5, it is not necessary to tighten it too much. Tighten it until the baffle 7 does not move when lightly pushed by hand, so as to ensure that the connecting rod 16 can be rotated to push and move, which is convenient for adjustment and use. For some positions that do not need to be adjusted, the connecting rod 16 can be removed and not used by utilizing the threaded connection relationship between the threaded rod 21 and the connecting rod 16.

[0036] In some embodiments, the top of the fixing buckle 3 is provided with a groove 18 corresponding to the position of the movable block 15, the bottom of the movable block 15 is located in the groove 18, and the top of the fixing block 14 is configured to protrude towards the top of the movable block 15. The movable block 15 is limited by the groove 18 and the protruding top of the fixing block 14.

[0037] The groove 18, together with the fixing block 14, restricts the forward and backward movement and the up and down movement of the movable block 15, so that when the connecting rod 16 rotates, it can stably drive the vertical plate 6 to move.

[0038] In some embodiments, two uprights 23 are provided, located at the bottom ends of the support beam 25 respectively, and two uprights 24 are provided, located between the two uprights 23. The support beam 25 has an opening, and the top part of the uprights 24 passes through the opening. The top of the support beam 25 has multiple equally spaced limiting grooves 30 corresponding to the opening position. The top of the uprights 24 is fixed with limiting blocks 29, which are located in the limiting grooves 30 for limiting support. The bottom of the uprights 23 is fixed with a fixing seat 26. The fixing platform 1 has a hole corresponding to the fixing seat 26. The fixing platform 1 and the fixing seat 26 are fixed together by bolts.

[0039] The first upright 23 is fixed to the fixed platform 1, while the second upright 24 can be adjusted to adapt to the placement requirements of copper busbar coils in different positions. When adjusting, lift the second upright 24 to move the limiting block 29 out of the limiting groove 30. At this time, the second upright 24 can be moved along the support beam 25. When it is moved to the required position, align the limiting block 29 with the nearest limiting groove 30, and then lower the second upright 24 so that the limiting block 29 falls into the limiting groove 30 to perform the limiting.

[0040] In some embodiments, lifting lugs 31 are fixed at both ends of the top of the support beam 25, and lifting lugs 32 are fixed at the two long sides of the top of the fixed platform 1.

[0041] The lifting lug 31 allows for easy lifting and removal of the support beam 25, as well as the uprights 23 and 24. The lifting lug 32 facilitates the lifting and fixing of the fixed platform 1 with the magnetic pole copper busbar coil, and its placement into the curing equipment or to the curing area.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
