Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing and processing, specifically a rotor silicon steel sheet stacking and pressurizing device. Background Technology

[0002] In the manufacturing process of electric motors, the rotor is one of the key components, and it is usually made of multiple layers of stacked silicon steel sheets. The stacking of these silicon steel sheets is to form a magnetic circuit, which helps to reduce eddy current losses and improve the efficiency of the device.

[0003] However, the stacking and pressurization of rotor silicon steel sheets has long been done manually, which is time-consuming, labor-intensive, and inefficient. Moreover, this is a delicate process that requires ensuring a tight bond between the silicon steel sheets and accurate alignment of the inner slots to achieve optimal electrical performance and mechanical stability. Therefore, overcoming the aforementioned technical problems and defects has become a key issue that needs to be addressed. Utility Model Content

[0004] The purpose of this invention is to overcome the defects described in the background art, thereby realizing a rotor silicon steel sheet stacking and pressurizing device. This device can pressurize the silicon steel sheets, increase the contact area between the silicon steel sheets, thereby improving the overall mechanical strength, reducing the air gap between the silicon steel sheets, increasing the magnetic density, improving the efficiency of the magnetic circuit, and also ensuring the cleanliness of the silicon steel sheet surface during stacking, ensuring the tight bonding between the silicon steel sheets, thereby ensuring the production quality of the rotor.

[0005] To achieve the above-mentioned objectives, the technical solution of this utility model is: a rotor silicon steel sheet stacking and pressurizing device, comprising a base, with a vertical plate fixedly disposed at the top of the base. A mounting plate is fixedly disposed on the side of the vertical plate, and a support rod for positioning the silicon steel sheets is horizontally fixedly disposed on the mounting plate. A cleaning module located above the silicon steel sheets is horizontally fixedly disposed at the top of the vertical plate. A pressurizing module for pressurizing the silicon steel sheets is horizontally fixedly disposed on the side of the vertical plate.

[0006] In the aforementioned rotor silicon steel sheet stacking and pressurizing device, a pad that can abut against the silicon steel sheets is fixedly provided on the side of the mounting plate. This facilitates cleaning, maintenance, and replacement of the pressurized areas of the silicon steel sheets.

[0007] The support rod is fixedly equipped with a flat key corresponding to the keyhole of the silicon steel sheet. The support rod is horizontally fixed to the side of the mounting plate above the base through a gasket. This allows for support and guidance of the silicon steel sheets during stacking, preventing skewing.

[0008] In the aforementioned rotor silicon steel sheet stacking and pressurizing device, the cleaning module includes a cleaning box fixedly mounted on the top of a vertical plate. A jet pipe is horizontally connected to the side of the cleaning box, located above and parallel to a support rod. The bottom end of the jet pipe has a jet nozzle facing the support rod. This allows for the blowing away of impurities and dust from the surface of the silicon steel sheets during stacking, ensuring the cleanliness of the silicon steel sheet surface during stacking.

[0009] An air intake fan with a motor is fixedly installed inside the cleaning box at the connection point with the jet pipe.

[0010] The cleaning box has a removable cover at its rear end, and a replaceable filter plate is installed inside the cleaning box between the air intake fan and the cover plate. This ensures the cleanliness of the air blown onto the silicon steel sheets, preventing dust from entering between the silicon steel sheets and affecting the rotor molding quality.

[0011] In the aforementioned rotor silicon steel sheet stacking and pressurizing device, a control cavity is provided inside the mounting plate. At least one adjustment groove is provided on the side of the mounting plate, and an adjustment rod is provided inside the control cavity, passing through the adjustment groove and the pad and parallel to the support rod. The adjustment rod can slide along the adjustment groove.

[0012] The adjusting groove has a sliding groove inside, and a sleeve that can slide in the sliding groove is fixedly installed on the adjusting rod. Multiple rollers that abut against the sliding groove are arranged in a circumferential array on the sleeve. The rollers are rotatably mounted on the sleeve and are parallel to the adjusting rod.

[0013] In the aforementioned rotor silicon steel sheet stacking and pressurizing device, a rotary cylinder is fixedly installed on the vertical plate inside the control chamber. A lever is fixedly installed at the output end of the rotary cylinder, and an arc-shaped groove is formed on the outer edge of the lever. The adjusting rod slides within the arc-shaped groove through a bearing fixedly installed at its end. This allows the adjusting rod to slide along the adjusting groove, achieving alignment of the stacked silicon steel sheets and ensuring the quality of the rotor after forming.

[0014] The diameter of the bearing is smaller than the width of the arc-shaped groove. This reduces relative friction, allowing the adjusting rod to slide more smoothly along the adjusting groove.

[0015] In the aforementioned rotor silicon steel sheet stacking pressurization device, the pressurization module includes a pressurization unit. The pressurization unit includes two vertically opposite moving rods on the top of the base. The moving rods are vertically and oppositely arranged on the base, and an anti-tilt plate is fixedly installed at the bottom end of the moving rods.

[0016] A hydraulic cylinder is horizontally fixed to the rear side of the upright plate, and a control plate is fixed to the telescopic end of the hydraulic cylinder. Pull rods are fixed to both sides of the control plate, and guide plates are fixed to both sides of the upright plate. The pull rods pass through the guide plates and are fixed to the sides of the corresponding moving rods. This allows the moving rods to move, applying pressure to the silicon steel sheets and increasing the contact area between them.

[0017] In the aforementioned rotor silicon steel sheet stacking and pressurizing device, the pressurization module further includes a lifting unit. The lifting unit comprises two horizontally positioned pressure plates above a base, which are raised and lowered on a movable rod. A positive and negative threaded screw and a guide rod are vertically mounted on the movable rod, and a bidirectional motor is fixedly mounted on the movable rod to drive the positive and negative threaded screws. Both the positive and negative threaded screws and the guide rod penetrate the pressure plates, with the pressure plates positioned at both ends of the positive and negative threaded screws. This allows for the raising and lowering of the pressure plates, facilitating the addition of silicon steel sheets.

[0032] The rotor silicon steel sheet stacking and pressurizing device of this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0033] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0034] See Figures 1-5The rotor silicon steel sheet stacking and pressurizing device of this embodiment can pressurize the silicon steel sheets, increase the contact area between the silicon steel sheets, thereby improving the overall mechanical strength, reducing the air gap between the silicon steel sheets, increasing the magnetic density, improving the efficiency of the magnetic circuit, and ensuring the cleanliness of the silicon steel sheet surface during stacking, ensuring a tight bond between the silicon steel sheets, thereby ensuring the production quality of the rotor. In this embodiment, it mainly includes a base 1, and a vertical plate 2 is fixedly installed at the top of the base 1. A mounting plate 3 is fixedly installed on the side of the vertical plate 2, and a pad 7 that can abut against the silicon steel sheets is fixedly installed on the side of the mounting plate 3. This realizes the pressurization of the silicon steel sheets and facilitates cleaning, maintenance and replacement of the pressurization position of the silicon steel sheets. A support rod 4 for positioning the silicon steel sheets is horizontally fixedly installed on the mounting plate 3. A flat key 8 corresponding to the keyhole of the silicon steel sheet is fixedly installed on the support rod 4, and the support rod 4 is horizontally fixedly installed on the side of the mounting plate 3 above the base 1 through the pad. The silicon steel sheet is placed on the support rod 4, and the flat key 8 is used for guidance to prevent it from tilting.

[0035] To ensure a tight bond between the silicon steel sheets. See also Figures 1-3 In this embodiment, a cleaning module 5 is horizontally fixed at the top of the upright plate 2, located above the silicon steel sheet. The cleaning module 5 includes a cleaning box 51 fixedly mounted at the top of the upright plate 2. A jet pipe 52 is horizontally connected to the side of the cleaning box 51, and the jet pipe 52 is located above the support rod 4 and parallel to the support rod 4. The bottom end of the jet pipe 52 has a jet nozzle 53 facing the support rod 4. This allows impurities and dust on the surface of the silicon steel sheet to be blown away during stacking, ensuring the surface of the silicon steel sheet is clean. An air intake fan 54 with a motor is fixedly mounted inside the cleaning box 51 at the connection with the jet pipe 52. A removable cover plate 55 is provided at the rear end of the cleaning box 51, and a replaceable filter plate 56 is provided inside the cleaning box 51 between the air intake fan 54 and the cover plate 55. The control motor operates, rotating the intake fan 54, thereby blowing the air filtered by the filter plate 56 through the jet pipe 52 and jet nozzle 53 onto the silicon steel sheets. This ensures the cleanliness of the air blown onto the silicon steel sheets and prevents dust from entering between the sheets, affecting the rotor forming quality. A guide plate is fixedly installed on the base 1 below the support rod 4. The guide plate has a triangular cross-section, which guides the air and dust blown from above to both sides, preventing dust from flowing back onto the silicon steel sheets.

[0036] To align the silicon steel sheets. In this embodiment, see... Figure 4 and Figure 5The mounting plate 3 has a control cavity 9 inside. At least one adjustment groove 10 is provided on the side of the mounting plate 3. An adjustment rod 11, passing through the adjustment groove 10 and the pad 7 and parallel to the support rod 4, is provided inside the control cavity 9. The adjustment rod 11 can slide along the adjustment groove 10. The adjustment rod 11 can be inserted into the through groove of the silicon steel sheet. A sliding groove 12 is provided inside the adjustment groove 10. A sleeve 13, which can slide within the sliding groove 12, is fixedly mounted on the adjustment rod 11. Multiple rollers 14, which abut against the sliding groove 12, are arranged in a circumferential array on the sleeve 13. The rollers 14 are rotatably mounted on the sleeve 13 and are parallel to the adjustment rod 11. A rotary cylinder 15 is fixedly mounted on the upright plate 2 inside the control cavity 9. The rotary cylinder 15 is mature existing technology and will not be described in detail here. The output end of the rotary cylinder 15 is fixedly provided with a lever plate 16, and an arc groove 17 is provided on the outer edge of the lever plate 16. The adjusting rod 11 slides in the arc groove 17 through a bearing 18 fixedly provided at its end.

[0037] The rotary cylinder 15 is controlled to operate, thereby rotating the dial plate 16. At this time, the arc groove 17 presses against the bearing 18, causing the adjusting rod 11 to move within the adjusting groove 10, achieving alignment of the stacked silicon steel sheets and ensuring the quality of the rotor after forming. During this process, the sleeve 13 moves continuously within the slide groove 12 via the roller 14, thereby reducing the resistance when the adjusting rod 11 moves within the adjusting groove 10, while ensuring the verticality of the adjusting rod 11.

[0038] The diameter of the bearing 18 is smaller than the width of the arc-shaped groove 17. This reduces relative friction, allowing the adjusting rod 11 to slide more smoothly along the adjusting groove 10.

[0039] To achieve pressure application to the silicon steel sheet. In this embodiment, see... Figure 1 and Figure 2A pressure boosting module 6 for pressurizing silicon steel sheets is horizontally fixed to the side of the upright plate 2. The pressure boosting module 6 includes a pressure unit 61. The pressure unit 61 includes two vertically opposite moving rods 611 on the top of the base 1. The moving rods 611 are vertically and oppositely arranged on the base 1, and an anti-tilt plate 612 is fixed to the bottom of the moving rods 611. The anti-tilt plate 612 prevents the moving rods 611 from tilting on the base 1. A hydraulic cylinder 613 is horizontally fixed to the rear side of the upright plate 2, and a control plate 614 is fixed to the telescopic end of the hydraulic cylinder 613. Pull rods 615 are fixed to the sides of both ends of the control plate 614, and guide plates 616 are fixed to both sides of the upright plate 2. The pull rods 615 pass through the guide plates 616 and are fixed to the sides of the corresponding moving rods 611. The hydraulic cylinder 613 is operated to extend and retract the control plate 614, which in turn pulls the pressure plate 621 relative to the silicon steel sheet via the tie rod 615, applying pressure to the silicon steel sheet and increasing the contact area between the silicon steel sheets. During this process, the guide plate 616 supports and guides the tie rod 615, and the anti-tilt plate 612 prevents the moving rod 611 from tilting on the base 1.

[0040] The pressurization module 6 also includes a lifting unit 62. The lifting unit 62 includes two horizontally arranged pressure plates 621 above the base 1, which are raised and lowered on a moving rod 611. A positive and negative threaded screw 622 and a guide rod 623 are vertically arranged on the moving rod 611. A bidirectional motor 624, which drives the positive and negative threaded screw 622 to rotate, is fixedly installed on the moving rod 611. Both the positive and negative threaded screw 622 and the guide rod 623 pass through the pressure plates 621, and the pressure plates 621 are respectively located at both ends of the positive and negative threaded screw 622. Controlling the bidirectional motor 624 drives the positive and negative threaded screw 622 to rotate, thereby raising and lowering the pressure plates 621, facilitating the addition of silicon steel sheets. During this process, the guide rod 623 provides guidance.

[0041] The method of using the rotor silicon steel sheet stacking and pressurizing device of this utility model is as follows: First, control the bidirectional motor 624 to drive the positive and negative threaded screws 622 to rotate, so that the pressure plate 621 moves in opposite directions on the positive and negative threaded screws 622 and the guide rod 623. At this time, the silicon steel sheets can be placed on the support rod 4 to abut against the pad 7, which facilitates subsequent cleaning and replacement. The silicon steel sheets are positioned by the flat key 8 and the adjusting rod 11. During this process, control the motor to rotate the air intake fan 54, so that the air filtered by the filter plate 56 is blown onto the silicon steel sheets through the jet pipe 52 and the jet port 53, ensuring the cleanliness of the air blown onto the silicon steel sheets and preventing dust from entering between the silicon steel sheets and affecting the rotor forming quality.

[0042] Once a certain number of silicon steel sheets are placed on the support rod 4, the rotary cylinder 15 is activated, causing the dial plate 16 to rotate. At this time, the arc-shaped groove 17 presses against the bearing 18, causing the adjusting rod 11 to move within the adjusting groove 10, achieving alignment of the stacked silicon steel sheets and ensuring the quality of the rotor after forming. During this process, the sleeve 13 moves continuously within the sliding groove 12 via the roller 14, thereby reducing the resistance of the adjusting rod 11 as it moves within the adjusting groove 10, while simultaneously ensuring the verticality of the adjusting rod 11.

[0043] Subsequently, the bidirectional motor 624 is controlled to operate, causing the pressure plate 621 to move relative to the guide rod 623 to a suitable position. The hydraulic cylinder 613 is then controlled to operate, extending and retracting the control plate 614, thereby pulling the pressure plate 621 relative to the silicon steel sheet via the tie rod 615, applying pressure to the silicon steel sheet and increasing the contact area between the sheets. During this process, the guide plate 616 provides support and guidance for the tie rod 615, and the anti-tilt plate 612 prevents the moving rod 611 from tilting on the base 1.
