Description

Technical Field

[0001] This utility model relates to the technical field of iron core production equipment, and in particular to an integral assembly tooling for a single-phase angled iron core. Background Technology

[0002] Because single-phase bent iron cores employ bending and shearing processes, the stress zone at the bending point is relatively small, thus eliminating the need for annealing. Furthermore, to improve coil wrapping efficiency, one or two opening structures are incorporated into the yoke or column of the single-phase bent iron core, with staggered seams at the openings, allowing for separate manufacturing of the coil and iron core. Therefore, the overall efficiency of bent iron cores is higher than that of wound iron cores.

[0003] Because the silicon steel sheets closer to the outer edge of each stage in a single-phase folded core are heavier, it is often difficult for workers to move multiple stages of silicon steel sheets at once. Therefore, traditional single-phase folded cores are generally assembled manually stage by stage, from the inside out, which undoubtedly leads to low assembly efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an integral assembly tooling for a single-phase angled iron core to solve one or more problems in the prior art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A single-phase angled iron core assembly fixture includes a stacking platform, a mounting frame spanning the stacking platform, and a positioning mechanism mounted on the mounting frame. The stacking platform includes a base frame and a roller conveyor mounted on the base frame. The positioning mechanism includes an inner support assembly and two outer support assemblies. The inner support assembly is located above the stacking platform to support the inner wall of the angled iron core, and the two outer support assemblies are located on both sides of the roller conveyor in the transmission direction to clamp the two sides of the angled iron core.

[0007] The above solution uses a roller conveyor as the worktable during assembly. The rolling friction is small, allowing workers to push more cores at a time for assembly, overcoming the problem that traditional assembly tables cannot be manually pushed and inserted. At the same time, it also reduces wear on the core end faces.

[0008] Furthermore, the external support assembly includes an electric cylinder and a positioning plate. The main body of the electric cylinder is fixed on a mounting frame located on one side of the stacking table. The output shaft of the electric cylinder is perpendicular to the roller conveying direction and connected to the positioning plate. The positioning plate is located above the stacking table and is arranged parallel to the roller conveying direction.

[0009] The above solutions allow for adjustments to the positioning plate based on the required core dimensions, and also enable the application of thrust via an electric cylinder to correct tilting during core assembly.

[0010] Furthermore, guide plates are provided at both ends of the positioning plate. One end of the guide plate is fixed to the positioning plate, and the other end of the guide plate is inclined to the side away from the center of the stacking table.

[0011] With the above solution, workers can place the core assembly materials for splicing onto the roller line at will. During the advancement process, the core assembly materials can easily come into contact with the guide plate first and gradually adjust back to the correct angle along the guide plate, saving time and manpower.

[0012] Furthermore, the inner support assembly includes a mounting base, two top inner support plates, and two side inner support plates. The mounting base is mounted on a mounting frame located above the stacking platform. Four connecting rods are connected to the side of the mounting base facing the stacking platform. The four connecting rods are respectively connected to the two top inner support plates and the two side inner support plates. The two top inner support plates are respectively close to both ends of the roller line, and the two side inner support plates are respectively close to both sides of the roller line.

[0013] Furthermore, all the connecting rods are slidably connected to the mounting base, and the sliding direction of the connecting rod used to connect the top inner support plate is parallel to the transmission direction of the roller line, while the sliding direction of the connecting rod used to connect the side inner support plate is perpendicular to the transmission direction of the roller line.

[0014] Furthermore, four sliders are slidably connected to the mounting base, and a cylinder is fixed on each slider. The output shafts of the four cylinders are respectively fixedly connected to four connecting rods. The mounting base is also provided with a drive assembly for driving the sliders to slide.

[0015] Furthermore, the roller line includes multiple rollers connected in sequence by hinges, and one end of the roller line is fixed to the base frame, while the other end of the roller line is slidably connected to the base frame.

[0016] The above scheme uses a movable hinge structure for the roller line, which allows the roller spacing to be adjusted within a certain range. This ensures both the stable operation of the iron core and the subsequent hoisting of the iron core.

[0017] Furthermore, both the top inner support plate and the side inner support plate are provided with arc-shaped guide surfaces.

[0018] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0019] 1. Using roller conveyors as assembly tables overcomes the problem that traditional assembly tables cannot rely on manual pushing and inserting, allowing workers to assemble more stages at a time, saving manpower. At the same time, rolling friction replaces sliding friction, reducing wear on the core end face.

[0020] 2. Using multiple guiding and positioning devices, there is no need for manual calculation of the core placement position in the early stage. The core can be placed arbitrarily, and the positioning of the core assembly can be completed by the subsequent guiding mechanism, saving time and manpower.

[0021] 3. The roller line adopts a movable hinge structure, which allows the roller spacing to be adjusted within a certain range, thereby ensuring the stable operation of the iron core and realizing the subsequent hoisting work of the iron core. Attached Figure Description

[0030] A single-phase angled iron core integral assembly fixture, see [link / reference] Figure 1 The system includes a stacking platform, a mounting frame 3 spanning the stacking platform, and a positioning mechanism mounted on the mounting frame 3. The stacking platform includes a base frame 2 and a roller conveyor 1 mounted on the base frame 2. The positioning mechanism includes an inner support assembly 5 and two outer support assemblies 4. The inner support assembly 5 is mounted on top of the mounting frame 3, directly facing the center of the stacking platform. The two outer support assemblies 4 are respectively mounted on the mounting frame 3 on either side of the roller conveyor 1 in the conveying direction.

[0031] See Figure 1 , Figure 2 The roller conveyor 1 comprises multiple rollers connected sequentially by hinges. One end of the roller conveyor 1 is bolted to one end of the base frame 2, and the other end of the roller conveyor 1 is slidably connected to the base frame 2. When the sliding end of the roller conveyor 1 moves away from its end fixed to the base frame 2, the distance between adjacent rollers increases; conversely, the distance between adjacent rollers decreases. When the distance between adjacent rollers is at its minimum, the entire roller conveyor 1 is in a contracted state; when the distance between adjacent rollers is sufficient for the lifting device to pass through, the entire roller conveyor 1 is in an extended state.

[0032] See Figure 3 The external support assembly 4 includes an electric cylinder 41, a positioning plate 42, and a telescopic rod 43. Guide plates 44 are provided at both ends of the positioning plate 42, and the two guide plates 44 are inclined towards the same side of the positioning plate 42. In this embodiment, the guide plates 44 are formed by bending the ends of the positioning plate 42. The output shaft of the electric cylinder 41 is perpendicular to the side of the positioning plate 42 and fixed at the center of the side of the positioning plate 42 located on the inclined side of the guide plate 44. Multiple telescopic rods 43 are arranged parallel to the output shaft of the electric cylinder 41, and these multiple telescopic rods 43 are spaced apart along the length of the positioning plate 42. Figure 1 The main body of the electric cylinder 41 is fixed on the mounting frame 3 located on one side of the stacking table. The output shaft of the electric cylinder 41 is horizontally oriented towards the other side of the stacking table, so that the positioning plate 42 is set parallel to the conveying direction of the roller line 1. The fixed end of the telescopic rod 43 is also fixed on the mounting frame 3, and the movable end of the telescopic rod 43 is fixed on the positioning plate 42. The two positioning plates 42 are arranged opposite each other on both sides of the stacking table, and form a V-shaped guide channel through the guide plate 44.

[0033] See Figure 1 The inner support assembly 5 includes a mounting base 51, two top inner support plates 52, and two side inner support plates 53. A slide rail 31 is provided on the top of the mounting frame 3, with the length direction of the slide rail 31 perpendicular to the conveying direction of the roller line 1. A movable frame 32 is slidably connected to the slide rail 31, and the mounting base 51 is fixed to the movable frame 32.

[0034] The movement of the movable frame 32 can be achieved by the cooperation of a linear motor or a lead screw and a drive motor; the corresponding structure is not shown in the figure.

[0035] See Figure 4 and Figure 5The mounting base 51 has a cavity with four through slots at the bottom that communicate with the outside. These four through slots are arranged in a cross shape, with two slots parallel to the conveying direction of the roller line 1 and the other two perpendicular to it. Each of the four through slots corresponds to a slider 55, which is located within the cavity of the mounting base 51 and slides along its corresponding through slot. A cylinder (not shown) is fixed to each slider 55. The cylinder's output shaft faces downwards and is connected to a connecting rod 54. The end of the connecting rod 54 away from the cylinder passes through the corresponding through slot and is outside the mounting base 51.

[0036] See Figure 5 , Figure 6 The ends of the four connecting rods 54 outside the mounting base 51 are respectively connected to two top inner support plates 52 and two side inner support plates 53. The two top inner support plates 52 are located near both ends of the roller line 1, and the two side inner support plates 53 are located near both sides of the roller line 1. Both the top inner support plates 52 and the side inner support plates 53 are provided with arc-shaped guide surfaces. The arc-shaped guide surfaces of the two top inner support plates 52 are arranged opposite to each other and face both ends of the roller line 1, and the arc-shaped guide surfaces of the two side inner support plates 53 are arranged opposite to each other and face both sides of the roller line 1.

[0037] See Figure 4 A drive assembly is also installed inside the cavity of the mounting base 51. The drive assembly includes two double-acting lead screws 56 and two worm gear reducers 57. The two double-acting lead screws 56 are staggered and perpendicularly arranged, each double-acting lead screw 56 corresponds to two sliders 55, and the two ends of the double-acting lead screws 56 are threaded to the two corresponding sliders 55. The two worm gear reducers 57 are used to drive the rotation of the two double-acting lead screws 56.

[0038] Implementation Principle: Prepare two sets of materials for the angled iron core, positioning the mounting base 51 directly above the stacking platform. Adjust the positions of the top inner support plate 52 and the side inner support plate 53 according to the window size of the iron core to be assembled. Then, adjust the distance between the positioning plate 42 and the side inner support plate 53 according to the column thickness of the iron core, ensuring that the roller line 1 is in a contracted state. Next, place the two sets of materials at both ends of the roller line 1, with one set initially pushed towards the center of the roller line 1. During this process, the material is guided by the guide plate 44 and the side inner support plate 53, ensuring that its side is parallel to the transmission direction of the roller line 1. Finally, the inner end face of the material abuts against the top inner support plate 52, and the side of the material is held in place by the positioning plate 42 and the side inner support plate 53. Then, push the other set of materials forward along the roller in the same manner until it is assembled with the first set. After the angled iron core is assembled, use plastic steel straps to tighten and fix it along the outer circumference of the iron core. After the iron core is fixed, pull the rollers from the movable end of roller line 1 to increase the distance between the rollers, and use a lifting tool to lift the iron core from the bottom.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
