Description

Technical Field

[0001] The utility model relates to the technical field of motor coil shaping equipment, in particular to a coil shaping machine for a high-speed and high-precision spindle motor. Background Art

[0002] Motors play an important role in the modern industrial field. They are mainly composed of two parts: the stator and the rotor. The stator part includes the frame, the stator core and the stator coil. The characteristics of high-speed motors are high rotor speed, high frequency of alternating winding current and magnetic flux in the core. Therefore, for the production and processing of high-speed motors, the quality of each processing link must be strictly controlled. Since the stator coil needs to be wound on the stator core, the shape of the coil is irregular after winding, which is not conducive to the subsequent insulation treatment of the two ends of the coil. Therefore, it is also necessary to shape the two ends of the coil to form a regular circle at both ends of the coil, so that the coil maintains a stable shape and position, thereby preventing the coil from loosening and deforming, which is conducive to the subsequent insulation treatment of the coil and improving the overall quality of the motor.

[0003] The stator coil is usually shaped by a motor coil shaping machine, such as the prior art "a motor coil shaping device" (publication number: CN113629956A), which can shape the outer circle and inner circle of the coil at the same time through a shaping mold, but the prior art still has the following technical problems:

[0004] The coil shaping equipment of the prior art needs to place the motor stator in the shaping area in the middle of the equipment, and when placing it, it is also necessary to ensure that the lower end of the stator accurately falls into the positioning groove of the lower tooling. However, for large stators, the volume of the positioning tooling needs to be made larger, and the work is likely to interfere with the shaping mold on the outer periphery of the stator, resulting in obstruction of the shaping mold stroke and failure to shape. At the same time, since the stator is loaded into the tooling in a vertical state, the positioning interface between the stator and the tooling is also easily blocked by the stator, which makes it easy for the operator to misjudge whether the stator is accurately loaded into the positioning interface, thereby causing the upper and lower shaping molds to be unable to penetrate into the coil of the stator during shaping, causing impact damage to the stator. Utility Model Content

[0005] The utility model provides a coil shaping machine for a high-speed and high-precision spindle motor, which can solve the problem that when the coil shaping equipment in the prior art is shaping a large stator, the positioning tooling is too large and easily interferes with the shaping die, and after the stator is installed in the tooling, the positioning interface of the tooling is blocked, which makes it easy for the operator to misjudge whether the stator is accurately installed in the positioning tooling, thereby causing the shaping die to be unable to accurately pass through the coil, unable to shape the coil, and easily causing impact damage to the stator.

[0006] The present application provides the following technical solution: A coil shaping machine for a high-speed and high-precision spindle motor, comprising a workbench and a frame fixed on the workbench, and also comprising an inner shaping mechanism slidably connected to the frame and an outer shaping mechanism fixed on both sides of the frame;

[0007] It also includes a loading mechanism fixed in the middle of the frame, the loading mechanism includes a loading platform and a loading platform, the loading platform includes a support column and a support block respectively fixed on the workbench, and a loading plate arranged above the support column and the support block, two support columns are provided, which are symmetrically arranged on both sides of the loading platform, and one end of the loading plate is rotatably connected between the two support columns;

[0008] A positioning hole is provided in the middle of the loading plate, and an L-shaped positioning plate is fixed on the loading plate;

[0009] The feeding mechanism also includes a lifting cylinder arranged on the workbench, the piston rod end of the lifting cylinder is pivotally connected to the bottom of the carrier plate, and one end of the lifting cylinder away from the carrier plate is pivotally connected to the workbench.

[0010] Beneficial effects:

[0011] 1. The motor stator can be placed on the loading table in a horizontal state, and the positioning hole on the loading plate is matched with the cross-sectional shape of the motor stator, so that the positioning hole of the loading plate can position the end of the stator. The loading mechanism is arranged on the front side of the shaping area, and the stator is placed in a horizontal state, so that the contact position between the stator and the loading plate will not be blocked, which is more conducive to the operator to visually confirm whether the stator is accurately inserted into the loading plate; then the piston rod of the lifting cylinder is retracted, and the loading plate is rotated from a vertical state to a horizontal state. The stator located in the positioning hole of the loading plate rotates with the loading plate, and rotates from a horizontal state to a vertical state. During the rotation process, the positioning hole and the positioning plate can fix and support the stator, so that the stator and the loading plate can be synchronously swung to the shaping working area in the middle of the equipment, and the stator and the positioning holes on the loading plate are not separated, so that the stator is always accurately positioned on the loading plate, which is conducive to the shaping mold to accurately penetrate into the middle hole of the stator coil, which can not only improve the shaping accuracy and effect of the stator coil, but also prevent the shaping mold from causing impact damage to the stator.

[0012] 2. After the stator coil shaping process is completed, the piston rod of the lifting cylinder extends out, pushing the loading plate from a horizontal state to a vertical state, thereby driving the motor stator to rotate from a vertical state to a horizontal state. After the motor stator rotates to a horizontal state, it returns to the loading platform, making it easier for the operator to take out the stator and improving the convenience of operation.

[0013] Furthermore, an L-shaped notch is provided on the top of the support block, and an end of the loading plate away from the support column can be inserted into the notch.

[0014] Beneficial effect: The notch on the support block facilitates the support of the carrier board when the carrier board is rotated from a vertical state to a horizontal state, thereby ensuring the support stability of the carrier board.

[0015] Furthermore, the loading platform includes a fixed block fixed on the workbench and a loading block detachably connected to the fixed block.

[0016] Beneficial effects: the loading block is convenient for supporting the motor stator and aligning the end of the stator with the positioning hole of the carrier plate, so as to achieve the purpose of quickly positioning the motor stator.

[0017] Furthermore, the frame includes a column fixed on the workbench and a top plate fixed on the upper end of the column, the internal shaping mechanism includes a sliding assembly slidably connected to the column and an upper cylinder fixed on the top plate, the sliding assembly includes a sliding sleeve slidably connected to the column, a slide fixed to the sliding sleeve and an internal shaping head threadedly connected to the bottom of the slide, and the piston rod end of the upper cylinder is threadedly connected to the top of the slide.

[0018] Beneficial effect: Driven by the upper cylinder, the slide plate and the inner shaping head can move up and down. The column has a guiding effect on the sliding sleeve to ensure the stability of the slide plate and the shaping head when they slide up and down. After the inner shaping head moves downward, it can penetrate into the inner hole of the motor stator below and extrude and shape the inner ring of the stator coil.

[0019] Furthermore, the external shaping mechanism is provided with two, which are symmetrically fixed on both sides of the feeding mechanism, and the external shaping mechanism includes a side cylinder fixed on the workbench and an external shaping component detachably connected to the end of the piston rod of the side cylinder, and the external shaping component includes a bar block fixed on the workbench, a vertical block slidably connected to the bar block, and an external shaping block screwed to the vertical block, and the end of the piston rod of the side cylinder is threadedly connected to the vertical block.

[0020] Beneficial effect: The side cylinder can drive the external shaping assembly to slide on the bar block, thereby controlling the external shaping block to approach the stator coil and limit it from the outside of the stator coil, and cooperate with the internal shaping head to extrude and fix the stator coil into shape.

[0021] Furthermore, each vertical block is provided with an upper and a lower outer shaping block.

[0022] Beneficial effect: After the motor stator is placed on the loading plate, the upper and lower outer shaping blocks can respectively fix the coils at the upper and lower ends of the motor stator, and cooperate with the inner shaping head to realize the extrusion and fixation of the coils.

[0031] Embodiment 1

[0032] like Figures 1 to 6 As shown, a coil shaping machine for a high-speed and high-precision spindle motor includes a workbench 1 and a frame fixed on the workbench 1, an inner shaping mechanism slidably connected to the frame, an outer shaping mechanism fixed on both sides of the frame, and a loading mechanism fixed in the middle of the frame.

[0033] The frame includes a column 3 fixed on the workbench 1 and a top plate 5 fixed on the upper end of the column 3 . Four columns 3 are provided to support the top plate 5 .

[0034] like Figure 1As shown, the internal shaping mechanism includes a sliding assembly slidably connected to the column 3 and an upper cylinder 6 fixed to the top plate 5 by screws. The sliding assembly includes four sleeves 4 slidably connected to the column 3, a slide plate 7 fixed between the four sleeves 4 and an internal shaping head 8 threadedly connected to the bottom of the slide plate 7. The slide plate 7 and the sleeve 4 are integrally formed. The piston rod end of the upper cylinder 6 is provided with an external thread, which can be threadedly connected to the upper surface of the slide plate 7. The upper end of the internal shaping head 8 is also provided with an external thread and is threadedly connected to the lower surface of the slide plate 7. Driven by the piston rod of the upper cylinder 6, the internal shaping head 8 can move up and down. At the same time, the column 3 guides the sleeve 4, which can improve the stability of the internal shaping head 8 sliding up and down.

[0035] The loading mechanism includes a loading platform and a loading platform, such as Figure 2 , Figure 3 and Figure 5 As shown, the loading platform includes a fixed block 16 fixed on the workbench 1 and a loading block 15 connected to the fixed block 16 by screws. The upper part of the loading block 15 is concave in shape, which can adapt to the outer contour of the motor stator and improve the stability of the motor stator placed on the loading block 15. A groove is provided in the middle of the loading block 15 to facilitate the screw to pass downward from the groove, thereby locking the loading block 15 to the fixed block 16.

[0036] like Figure 2 and Figure 3 As shown, the loading platform includes a support column 12 and a support block 18 respectively welded and fixed on the workbench 1, and a loading plate 13 arranged above the support column 12 and the support block 18. Figure 2 As shown, there are two support columns 12, which are symmetrically arranged on both sides of the loading platform. Figure 3 As shown, one end of the carrier plate 13 is pivotally connected between the two support columns 12, so that the carrier plate 13 can rotate between the two support columns 12; the support block 18 is arranged at the end away from the support column 12, and an L-shaped notch is arranged on the top of the support block 18. When the carrier plate 13 rotates to a horizontal state, the end of the carrier plate 13 away from the support column 12 can be inserted into the notch, so that the support block 18 supports the carrier plate 13; Figure 2 As shown, a positioning hole 131 is provided in the middle of the carrier plate 13. The positioning hole 131 is a stepped hole. The size in the middle of the stepped hole is larger than the outer circle size of the stator coil but smaller than the outer contour size of the stator, so that the step in the positioning hole 131 forms a support for the stator end surface, and the stator coil can pass through the positioning hole 131. An L-shaped positioning plate 14 is also fixed to the carrier plate 13 by screws. When the carrier plate 13 is in a vertical state, the positioning plate 14 remains horizontal, so that when one end of the stator extends into the positioning hole 131, the positioning plate 14 forms an auxiliary support for the outside of the stator;

[0037] like Figure 3As shown, the loading mechanism also includes a lifting cylinder 17 arranged on the workbench 1, a protrusion is provided at the bottom of the carrier plate 13, the piston rod end of the lifting cylinder 17 is pivotally connected to the protrusion at the bottom of the carrier plate 13, a connecting block 19 is fixed on the workbench 1, and one end of the lifting cylinder 17 away from the carrier plate 13 is pivotally connected to the connecting block 19 on the workbench 1, and the piston rod of the lifting cylinder 17 can drive the carrier plate 13 to rotate relative to the support column 12.

[0038] like Figure 1 and Figure 4 As shown, there are two external shaping mechanisms, which are symmetrically fixed on both sides of the feeding mechanism. The external shaping mechanism includes a side cylinder 2 fixed to the workbench 1 by screws and an external shaping component threadedly connected to the end of the piston rod of the side cylinder 2. The external shaping component includes a bar block 11 fixed to the workbench 1 by screws, a vertical block 10 slidably connected to the bar block 11, and an external shaping block 9 screwed to the vertical block 10; the piston rod end of the side cylinder 2 is provided with a thread, which can be threadedly connected to the vertical block 10, the bottom of the vertical block 10 is provided with a protrusion, the bar block 11 is provided with a slide groove, the bottom of the vertical block 10 is slidably connected in the slide groove of the bar block 11, each vertical block 10 is provided with an upper and lower external shaping block 9, and a semicircular groove is opened in the middle of the external shaping block 9. Driven by the piston rod of the side cylinder 2, Figure 4 When the two outer shaping blocks 9 on the left and right sides move toward the middle and are butted together, the semicircular grooves on the outer shaping blocks 9 can form a complete circular hole shape.

[0039] The method of using this device is as follows:

[0040] like Figure 6 As shown, the stator 20 is placed on the loading block 15. The concave shape of the upper part of the loading block 15 can adapt to the outer contour of the stator. At the same time, one end of the stator 20 is inserted into the positioning hole 131 in the middle of the carrier plate 13. Then the piston rod of the lifting cylinder 17 is retracted to rotate the carrier plate 13 in the vertical state to the horizontal state. The stator 20 rotates with the carrier plate 13, so that the stator 20 leaves the loading block 15 and rotates from the horizontal state to the vertical state. In the process of rotation, the positioning holes 131 on the carrier plate 13 and the positioning plate 14 form support for the stator to prevent the stator 20 from falling during the rotation. After the stator 20 rotates to the vertical state, the side cylinder 2 is started. Driven by the piston rod of the side cylinder 2, Figure 4The outer shaping blocks 9 on the left and right sides of the stator 20 move toward the middle. When the two outer shaping blocks 9 on the left and right sides are connected together, the semicircular grooves on the outer shaping blocks 9 can limit the outer circles of the coils at the upper and lower ends of the stator 20. Then the upper cylinder 6 is started. Driven by the piston rod of the upper air, the inner shaping head 8 penetrates into the inner hole in the center of the stator 20 from top to bottom. Relying on the extrusion of the inner shaping head 8 and the outer shaping block 9, the shape of the coil is shaped and fixed. After completing the shaping process, the piston rods of the upper cylinder 6 and the side cylinder 2 are retracted in turn, and the piston rod of the lifting cylinder 17 is extended to lift the loading plate 13 from a horizontal state to a vertical state, so that the stator 20 returns to the loading block 15, and the operator can remove the shaped stator 20.

[0041] The above is only an embodiment of the utility model. The utility model is not limited to the field involved in this implementation case.
