Description

Technical Field

[0001] The present invention relates to the technical field of stator assembly, and particularly to a shaping device for an ultra-long stator. Background Art

[0002] A stator is the stationary part of a motor or a generator, and mainly consists of a stator core and coils wound around the stator core. During the stator assembly process, the stator core needs to be wound and the coils need to be embedded. At this time, the coils are in an irregular shape at the end of the stator, which is not conducive to the processing of subsequent processes. Therefore, in order to ensure the precise shape of the coils after installation, a shaping device is usually required to sort out the coils of the stator.

[0003] Existing stator shaping devices generally adopt vertical shaping devices. The stator is fixed on a shaping workbench, an upper shaping die is arranged above the stator, and a lower shaping die is arranged below the stator. However, this vertical shaping device is not suitable for shaping ultra-long stators. For example, the stator of a deep well pump is much longer than a conventional stator. Using this vertical shaping device will result in a very high height of the entire device, unstable structure, and inconvenient feeding. Therefore, it is necessary to develop a shaping device for ultra-long stators. Summary of the Invention

[0004] The present invention aims to provide a shaping device for an ultra-long stator to overcome the deficiencies in the prior art.

[0005] To solve the above technical problems, the technical solution of the present invention is: a shaping device for an ultra-long stator, including a chassis, a workbench, a flipping mechanism, and a loading trolley. On both sides above the chassis, there are workbenches connected by columns. On both sides of the chassis, there are also upper brackets connected to the workbenches. An upper die and a lifting mechanism I for driving the upper die are arranged on the upper brackets. A flipping mechanism is arranged between the workbenches. The flipping mechanism includes a flipping plate, a flipping shaft, and a flipping motor. Bearing seats are arranged at both ends of the flipping shaft, and the bearing seats are fixed on the workbench. A flipping shaft sleeve rotatably connected thereto is also arranged on the flipping shaft, and the flipping shaft sleeve is connected to the flipping plate. The flipping motor is fixed under the workbench through a motor seat. One end of the flipping shaft is connected to the flipping motor through a chain drive structure. A lower die is arranged on the flipping plate, and a die core for positioning the stator is arranged on the lower die. The die core spreads the non-lead end wire package and assists the stator to flip. The loading trolley is a mobile trolley, and a positioning structure for the stator is arranged thereon. The stator on the loading trolley cooperates with the die core. During shaping, the flipping mechanism is in a horizontal state. The loading trolley moves the stator to the loading side of the chassis, moves the stator to make the stator dock with the die core, sleevs the stator on the die core, and then the flipping mechanism is started to flip 90°. The flipping mechanism flips to a vertical state and is directly below the upper die. By means of the flipping mechanism and arranging the lower die on the flipping mechanism, the ultra-long stator is fed horizontally during feeding, greatly reducing the occupied height of the device, making the entire structure more stable, and improving the feeding speed.

[0006] Further, the shaping device for the ultra-long stator further includes a guiding assembly, which includes a guiding plate and guiding wheels. There are two symmetrically arranged guiding plates on one side of the chassis. One end of the guiding plate away from the chassis is provided with a guiding part inclined outward, presenting a flared opening, which is convenient for the docking of the guiding wheels and the guiding plate. A guiding seat corresponding to the guiding plate is provided on the loading trolley, and a plurality of guiding wheels are arranged on the guiding seat, and the guiding wheels cooperate with the guiding plate. Through the arrangement of the guiding assembly, the stator can be inserted into the die core more quickly and accurately.

[0007] Further, for the shaping device for the ultra-long stator, adjusting foot pads are provided at the four corners of the chassis. The upper support includes columns and a top plate. One end of the column is connected to the top plate, and the other end passes through the workbench and is connected to the chassis.

[0008] Further, for the shaping device for the ultra-long stator, the flipping mechanism further includes a limiting mechanism, which includes a buffer limiting component and a locking component. The buffer limiting component includes a first buffer limiting component for restricting the horizontal state position of the flipping plate on the loading side of the workbench and a second buffer limiting component for restricting the vertical state position of the flipping plate; the locking components are relatively arranged on both sides of the workbench, including locking seats, locking cylinders and locking rods. The locking seats are fixed on the workbench, the locking cylinders are fixed on the locking seats, and the output ends thereof are connected with locking rods, and the locking rods cooperate with the flipping plate.

[0009] Further, for the shaping device for the ultra-long stator, the first lifting mechanism includes a first motor, a first lead screw synchronous pulley, a first lead screw and a first nut seat.

The first lead screw synchronous pulley is fixed on the first nut seat, and the first lead screw synchronous pulley is connected with the first main synchronous pulley through a synchronous belt. A connecting plate is provided at the upper ends of the two first lead screws, and the lower ends are connected to the upper moving plate. When the first motor rotates, it drives the first main synchronous pulley to rotate, thereby driving the two first lead screw synchronous pulleys to rotate. The rotation of the first lead screw synchronous pulley drives the first nut seat to rotate, thereby driving the first lead screw to move up and down. The movement of the first lead screw drives the upper moving plate to lift.

[0010] Further, for the above-mentioned shaping device for an ultra-long stator, the upper die includes an upper end die and a split shaping die. The split shaping die of the upper die is arranged on a movable carrier plate. Both ends of the movable carrier plate are sleeved on a column and are slidably connected to the column. A plurality of upper guide rods are arranged on the movable carrier plate and are elastically connected to an upper moving plate through the upper guide rods, upper guide sleeves and a first spring. The upper ends of the upper guide rods are inserted into the upper moving plate, and upper guide sleeves for limiting are arranged at the tops thereof. The outer sides of the upper guide rods are also sleeved with a first spring arranged between the upper moving plate and the movable carrier plate. The upper end die is arranged on the upper moving plate and includes an upper end sleeve. The upper end sleeve includes an upper cone sleeve at the bottom for controlling the inner diameter of the non-lead end of the stator and an upper end pressing sleeve arranged outside the upper end of the upper cone sleeve for controlling the height of the non-lead end of the stator. During shaping, the downward movement of the upper moving plate drives the lower die to move downward. When the movable carrier plate moves to the lower stroke position, it stops, the first spring is compressed, and the upper moving plate moves downward along the upper guide rods, thereby driving the upper end die thereon to continue moving downward. After reaching the position, the lower end die starts shaping.

[0011] Further, for the above-mentioned shaping device for an ultra-long stator, the split shaping die includes a die base, a shaping block base, a shaping movable disk, a tooth guard movable disk, a clamping block, and tooth guards. The shaping block base is arranged on the movable carrier plate or the flipping plate. A die base is connected below the shaping block base. A tooth guard base is connected below the die base. A shaping movable disk is arranged between the shaping block base and the die base. A tooth guard movable disk is arranged between the die base and the tooth guard base. A plurality of arc-shaped long grooves 1 tangent to the inner circle thereof are arranged on the tooth guard movable disk. A bushing 1 in contact with the inner wall thereof is arranged in the arc-shaped long groove 1. The bushing 1 is connected to the tooth guard through a pin shaft. A plurality of chutes 1 corresponding to the tooth guards are uniformly arranged on the tooth guard base. The tooth guards are arranged in the chutes 1 and are slidably connected to the chutes 1. A plurality of arc-shaped long grooves 2 tangent to the inner circle thereof are arranged on the shaping movable disk. A bushing 2 in contact with the inner wall thereof is arranged in the arc-shaped long groove 2. The clamping block includes an integrally formed clamping block portion and a clamping block connecting plate. The bushing 2 is connected to the clamping block connecting plate through a pin shaft. A plurality of chutes 2 corresponding to the clamping blocks are uniformly arranged on the shaping block base. The clamping block connecting plate is arranged in the chutes 2 and is slidably connected to the chutes 2.

The arc-shaped long groove 1 drives the tooth guards to move towards the center of the die base along the chutes 1, and a plurality of tooth guards contract towards the center, which can prevent the wire coil from collapsing. The arc-shaped long groove 2 drives the clamping blocks to move towards the center of the die base along the chutes 2, and a plurality of clamping blocks contract towards the center to form a circular sleeve to control the outer diameter size of the wire coil.

[0012] Further, in the above-described shaping device for the ultra-long stator, hinge seats protruding from the die base are provided on the outer peripheral sides of the shaping movable plate and the tooth guard movable plate. A pull rod is connected to the hinge seats. One side of the movable carrier plate or the turning plate is connected to a shaping cylinder through a cylinder seat. The output end of the shaping cylinder is connected to the pull rod. An annular groove is provided at the upper end of the die base, and an annular boss is provided at the lower end. The shaping movable plate is inserted into the annular groove, and the tooth guard movable plate is sleeved outside the annular boss. The shaping movable plate and the tooth guard movable plate are rotationally connected to the die base through the shaping cylinder and rotate around the center of the die base. Through the settings of the annular groove and the annular boss, the rotation of the shaping movable plate and the tooth guard movable plate is guided.

[0013] Further, in the above-described shaping device for the ultra-long stator, a second lifting mechanism for driving the lower die is further provided on the chassis between the workbenches. The second lifting mechanism includes a support plate, a second motor, a second lead screw synchronous pulley, a second lead screw, and a second nut seat. The support plate is fixed above the chassis through a support rod. The second motor is fixed on the support plate through a motor seat. The output end of the second motor is connected to a main synchronous pulley. The second nut seat is sleeved with a second lead screw threadedly connected thereto and is connected to the support plate through a bearing seat. Covers are provided at both ends of the bearing seat to prevent dust from entering the bearing seat. The second lead screw synchronous pulley is fixed on the second nut seat. The second lead screw synchronous pulley is connected to the main synchronous pulley through a synchronous belt. The upper end of the second lead screw is connected to a lower movable plate, and the lower end is connected to a limit plate. Linear bearings sleeved outside the columns are provided at both ends of the lower movable plate and are slidably connected to the columns through the linear bearings. When the second motor rotates, it drives the main synchronous pulley to rotate, thereby driving the second lead screw synchronous pulley to rotate. The rotation of the second lead screw synchronous pulley drives the second nut seat to rotate, thereby driving the second lead screw to move up and down. The movement of the second lead screw drives the lower movable plate to lift and lower. When the lower movable plate rises, it drives the limit rod and the die core mounting plate to rise and compress the second spring, thereby driving the lower guide rod to rise. The rise of the lower guide rod drives the rise of the lower end sleeve, thereby driving the shaping of the lower end die.

[0014] Furthermore, for the above-mentioned shaping device for the ultra-long stator, the lower die includes a lower end die and a split shaping die. The split shaping die of the lower die is arranged on the turning plate. The lower end die includes a lower end sleeve and a die core seat.

The flipping motor 23 is fixed below the workbench 12 through a motor base, and one end of the flipping shaft 22 is connected to the flipping motor 23 through a chain drive structure. A lower die 6 is provided on the flipping plate 21. A die core 61 for positioning the stator is provided on the lower die 6. The die core 61 spreads the non-lead end wire package and assists in flipping the stator 9. The loading trolley 3 is a mobile trolley, and a positioning structure for the stator is provided thereon. The stator 9 on the loading trolley 3 cooperates with the die core 61. During shaping, the flipping mechanism 2 is in a horizontal state. The loading trolley 3 moves the stator 9 to the loading side of the chassis 11, aligns the stator 9 with the die core 61, slews the stator 9 onto the die core 61, and then the flipping mechanism 2 is activated to flip 90°. The flipping mechanism flips to a vertical state and is directly below the upper die 4. Through the flipping mechanism 2 and the lower die 6 provided on the flipping mechanism 2, the ultra-long stator is horizontally loaded during feeding, greatly reducing the occupied height of the equipment, making the entire structure more stable, and improving the feeding speed.

An outwardly inclined guiding portion 311 is provided at one end of the guiding plate 31 away from the chassis 11, presenting a flared opening for facilitating the docking of the guiding wheels 32 with the guiding plates 31. A guiding seat 33 corresponding to the guiding plates 31 is provided on the loading trolley 3, and a plurality of guiding wheels 32 are provided on the guiding seat 33. The guiding wheels 32 cooperate with the guiding plates 31. Through the arrangement of the guiding assembly, the stator 9 can be inserted into the die core 61 more quickly and accurately.

The lower end sleeve 62 includes a lower cone sleeve 621 at the top for controlling the inner diameter of the stator lead end and a lower end pressing sleeve 622 arranged outside the lower part of the lower cone sleeve 621 for controlling the height of the stator lead end.

[0052] The working principle of the shaping device for the ultra-long stator of the present invention is as follows: The initial state of the turning plate 21 is a horizontal state. Move the feeding trolley 3, and the feeding trolley 3 is docked with the chassis 11 through the guiding assembly. The stator 9 is inserted onto the die core 61 through the feeding trolley 3. The turning motor 23 is started, and the turning plate 21 is turned from the horizontal state to the vertical state. Then, the first lifting mechanism 5 and the second lifting mechanism 8 are started, and then the upper die 4 and the lower die 6 are started for shaping. After the shaping is completed, the first lifting mechanism 5 and the second lifting mechanism 8 retract to their original positions. The turning motor 23 is started again, and the turning plate 21 drives the stator 9 to rotate to the horizontal state. At this time, the stator can be unloaded through the feeding trolley 3, and the shaping of one stator is completed.
