Description

A stator plastic-coated part sprue device Technical Field

[0001] This invention belongs to the technical field of stator plastic-coated parts processing, and particularly relates to a device for removing sprues from stator plastic-coated parts. Background Technology

[0002] Stator plastic-coated parts are suitable for various motor stator insulation, sealing, and structural fixing processes. As the core fixed component of a motor, the external plastic coating of the stator is a key process in motor production. Through the tight integration of the plastic-coated parts with the stator core and windings, insulation protection and waterproof sealing of the stator can be achieved, while strengthening the overall structural integrity of the stator, improving its vibration resistance and wear resistance during motor operation, and ensuring the stable and reliable operation of the motor.

[0003] Currently, existing de-sprue processing devices for plastic-coated annular stators have significant structural defects and functional deficiencies. Due to the unique structure of plastic-coated annular stators, residual sprue material may remain on the upper and lower end faces and the inner and outer ring sides. Existing devices cannot simultaneously de-sprue the upper and lower end faces and inner and outer ring sides according to actual processing requirements, and can only perform processing in stages and on different parts. This processing method not only significantly extends the de-sprue processing cycle of the plastic-coated stator parts, reduces overall processing efficiency, and increases labor and equipment costs, but also easily leads to inconsistent de-sprue precision in different parts due to staged processing, resulting in problems such as burrs on edges and corners and dimensional deviations, affecting the processing quality of the plastic-coated stator parts and their subsequent assembly compatibility. Therefore, a de-sprue processing device for plastic-coated stators that can solve the above problems is proposed. Summary of the Invention

[0004] This invention provides a desprue device for stator plastic-coated parts, aiming to solve the problems of existing desprue devices for annular stator plastic-coated parts, which have obvious structural defects and functional deficiencies. Due to the special structure of annular stator plastic-coated parts, sprue material may remain on the upper and lower end faces and the inner and outer ring sides. Existing devices cannot simultaneously perform desprue operations on the upper and lower end faces and inner and outer ring sides of the annular stator plastic-coated parts according to actual processing requirements, and can only perform processing operations in stages and on different parts. This processing method not only significantly prolongs the desprue processing cycle of stator plastic-coated parts, reduces the overall processing efficiency, and increases the input costs of labor and equipment, but also easily leads to inconsistent desprue precision in different parts due to staged processing, resulting in problems such as burrs on edges and corners and dimensional deviations.

[0009] Preferably, the adjustment unit includes a rotating ring disposed on the motherboard, and a first spacing adjustment unit is disposed on the rotating ring, the first spacing adjustment unit being used to adjust the spacing between the two sets of drain outlet blocks.

[0010] Preferably, the first spacing adjustment unit includes a first adjustment motor, which is a bidirectional motor. The upper and lower ends of the bidirectional motor are respectively connected to the first connecting plate and the rotating ring via a third connecting rod.

This significantly shortens the desinking processing cycle, reduces labor and equipment input costs, effectively improves overall processing efficiency, and solves the problem of low processing efficiency in existing devices.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This invention provides a stator plastic-coated part dewatering device, as shown in Figures 1-6. It includes: a placement main board 1 for placing the plastic-coated part body 2; a dewatering assembly disposed on the placement main board 1; and a limiting unit disposed on the placement main board 1. The limiting unit, also mounted on the placement main board 1, securely limits the plastic-coated part body 2 placed on the main board, preventing the plastic-coated part from shaking or shifting during the operation of the dewatering assembly. This ensures the dewatering assembly can accurately align with the residual dewatering position, guaranteeing dewatering accuracy. It is used to limit the plastic-coated part body 2 for dewatering. The desprue assembly performs desprue removal operations. The desprue assembly includes desprue blocks 3, which are arranged symmetrically in pairs. Each desprue block has a desprue bevel 4, which is connected to the placement main board 1 through an adjustment unit. The bevel is polished to conform to the edge contour of the plastic-coated part, enabling rapid scraping and polishing of the desprue material and reducing burr generation. The desprue blocks 3 are connected to the placement main board 1 through the adjustment unit. The position, angle, and spacing of the desprue blocks 3 can be flexibly adjusted through the adjustment unit to adapt to annular stator plastic-coated parts of different sizes and with different desprue residue positions, thereby improving the versatility of the device.

[0021] The lower end of the motherboard 1 is provided with a plurality of symmetrically arranged support legs 5.

[0022] The limiting unit includes a limiting cylinder 6, which is fixedly connected to the placement main board 1. The output end of the limiting cylinder 6 is fixedly connected to a first limiting block 8 via a first connecting rod 7. The upper end of the placement main board 1 is fixedly connected to a first connecting ring 10 via multiple second connecting rods 9 arranged in a circumferential array. Multiple second limiting blocks 11 arranged in a circumferential array are inserted on the first connecting ring 10. The second limiting blocks 11 can slide radially along the first connecting ring 10, which facilitates adjusting the limiting position according to the size of the plastic-coated part.

[0023] To improve the tightness and stability of the limiting mechanism, a first inclined surface 12 is provided on the first limiting block 8, and a second inclined surface 13 adapted to the first inclined surface 12 is provided on the second limiting block 11. The first inclined surface 12 and the second inclined surface 13 fit together to form a wedge-shaped limiting structure, which can realize bidirectional limiting of the plastic-coated part. At the same time, a snap-fit ​​protrusion 14 is provided on the second inclined surface 13, and a first snap-fit ​​groove 15 that cooperates with the snap-fit ​​protrusion 14 is provided on the first inclined surface 12. The snap-fit ​​protrusion 14 snaps into the first snap-fit ​​groove 15, which can prevent relative sliding between the first limiting block 8 and the second limiting block 11, and further improve the limiting accuracy.

[0024] In addition, an anti-slip protrusion 16 is fixedly connected to the end of the second limiting block 11. The anti-slip protrusion 16 is made of rubber material and has good anti-slip performance. It can enhance the friction between the second limiting block 11 and the plastic-coated part, prevent the plastic-coated part from rotating or displacing, and avoid scratching or wear on the surface of the plastic-coated part during the limiting process, thus protecting the processing surface quality of the plastic-coated part.

[0025] The end of the second limiting block 11 is fixedly connected with an anti-slip protrusion 16.

[0026] The adjustment unit is used to adjust the position and spacing of the drain block 3 to adapt to different sizes of plastic-coated parts and the drain requirements of different parts. The adjustment unit includes a rotating ring 17 disposed on the main board 1. The rotating ring 17 is provided with a first spacing adjustment unit, which is used to adjust the spacing between the two sets of drain blocks 3.

[0027] The first spacing adjustment unit includes a first adjusting motor 18, which is a bidirectional motor. The upper and lower ends of the bidirectional motor are respectively connected to the first connecting plate 21 and the rotating ring 17 via a third connecting rod 19. A reciprocating screw 20 is fixedly connected to the output end of the first motor. The lower end of the reciprocating screw 20 is rotatably connected to the rotating ring 17, and the upper end of the reciprocating screw 20 is rotatably connected to the first connecting plate 21. A reciprocating slider 22 is sleeved on the outside of the reciprocating screw 20. The third connecting rod 19 passes through the reciprocating slider 22. The reciprocating slider 22 is connected to the connecting block 24 via an adjusting rod 23. The adjusting rod 23 is a telescopic rod. The reciprocating slider 22 is connected to the connecting block 24 via the adjusting rod 23. The adjusting rod 23 is a telescopic rod, and its length can be adjusted according to actual needs, thereby adjusting the height position of the sprue block 3 to adapt to the sprue requirements of the upper and lower end faces of the plastic-coated part, and realizing the synchronous removal of sprue material from the upper and lower end faces.

[0028] The connecting block 24 is connected to the drain block 3 via the second spacing adjustment unit.

[0029] The second spacing adjustment unit includes a rotating rod 25, with a rotating handle 26 fixedly connected to the end of the rotating rod 25. The rotating rod 25 is provided with two symmetrically arranged external threads 27, with opposite thread directions. The sprue block 3 is threadedly connected to the external threads 27. When the operator rotates the rotating handle 26, the rotating rod 25 rotates accordingly. Since the two external threads 27 have opposite thread directions, the two symmetrically arranged sprue blocks 3 will move towards or away from each other along the axial direction of the rotating rod 25, thereby achieving fine adjustment of the spacing between the two sprue blocks 3. This adapts to annular stator plastic-coated parts with different inner and outer diameters, ensuring that the sprue blocks 3 can tightly fit the inner and outer ring sides of the plastic-coated parts, accurately removing sprue material, while avoiding incomplete sprue removal or damage to the surface of the plastic-coated parts due to improper spacing adjustment.

[0030] The drain block 3 is divided into two sections. One section, with the drain inclined surface 4, is rotatably connected to the other section of the drain block 3 via a first rotating shaft 28. An adjusting crank rod 29 is fixedly connected to the lower drain block 3, and an adjusting groove 30 is provided on the upper drain block 3. An adjusting rubber ball 31 is fixedly connected to the adjusting crank rod 29. The adjusting groove 30 is provided with multiple second locking grooves 32 that cooperate with the adjusting rubber ball 31. When it is necessary to adjust the angle of the drain inclined surface 4, it can be manually rotated. In the working section, the adjusting rubber ball 31 on the adjusting crank 29 is disengaged from the current second locking groove 32. After rotating to a suitable angle, the adjusting rubber ball 31 is locked into the corresponding second locking groove 32, thus fixing the angle of the working section. Through this structure, the angle of the sprue slope 4 can be flexibly adjusted to adapt to different tilt angles of the plastic-coated parts' edges and corners and sprue residue, ensuring that the sprue slope 4 can fully fit the sprue material, completely remove residual sprue, and avoid problems such as burrs and dimensional deviations caused by improper angle.

[0031] First, the operator places the annular stator plastic-coated body 2 on the upper surface of the main board 1 and adjusts the position of the plastic-coated part so that its center is aligned with the center of the main board 1. Then, the limiting cylinder 6 is activated. The output end of the limiting cylinder 6 pushes the first connecting rod 7 and the first limiting block 8 towards the plastic-coated part. The first inclined surface 12 of the first limiting block 8 fits against the second inclined surface 13 of the second limiting block 11, pushing the second limiting block 11 radially along the first connecting ring 10 until the anti-slip protrusion 16 at the end of the second limiting block 11 tightly fits against the inner or outer wall of the plastic-coated part. Simultaneously, the engaging protrusion 14 engages into the first engaging groove 15, completing the limiting and fixing of the plastic-coated part. Next, according to the size of the plastic-coated part and the location of the sprue residue, the position and spacing of the sprue block 3 are adjusted using the adjusting unit: rotating the rotating ring 17 adjusts the circumferential position of the sprue block 3. Each set of sprue blocks 3 corresponds to a processing part of the plastic-coated part; the first adjusting motor 18 is started, the bidirectional motor drives the reciprocating screw 20 to rotate, and the reciprocating slider 22 moves up and down along the reciprocating screw 20. At the same time, the height of the sprue blocks 3 is adjusted by the telescopic rod so that the sprue bevel 4 fits the upper and lower end faces of the plastic-coated part; the rotating handle 26 is rotated, and the spacing of the sprue blocks 3 is finely adjusted by the second spacing adjustment unit so that the sprue bevel 4 fits the inner and outer ring sides of the plastic-coated part; the angle of the working section of the sprue blocks 3 is adjusted according to the angle of the sprue residue to ensure that the sprue bevel 4 fully fits the sprue material; finally, the sprue assembly is started, and multiple sprue blocks 3 work synchronously to remove the sprue material from the upper and lower end faces and inner and outer ring sides of the plastic-coated part. After the operation is completed, the drive mechanism and the limit cylinder 6 are turned off, the limit unit is released, and the processed plastic-coated part can be taken out.

[0032] Improve processing efficiency and shorten processing cycle: This device, through multiple sets of symmetrically arranged desink blocks 3, combined with the flexible adjustment of the adjustment unit, can simultaneously perform desinking operations on the upper and lower end faces and inner and outer ring sides of the annular stator plastic-coated parts. It eliminates the need for processing in multiple stages or parts, significantly shortens the desinking processing cycle, reduces labor and equipment input costs, effectively improves overall processing efficiency, and solves the problem of low processing efficiency of existing devices.

[0033] Ensuring processing precision and improving product quality: The wedge-shaped limiting structure and anti-slip design of the limiting unit achieve precise positioning of the plastic-coated parts, avoiding displacement deviation during operation; at the same time, the angle and spacing of the sprue block 3 can be flexibly adjusted to ensure that the sprue bevel 4 can fully fit the sprue residue position, effectively reducing problems such as edge burrs and dimensional deviations, ensuring the consistency of sprue precision in various parts, improving the processing quality of the stator plastic-coated parts, and ensuring their compatibility in subsequent assembly.

[0034] High versatility and wide applicability: Through the adjustment unit, the second spacing adjustment unit and the angle adjustment structure of the sprue block 3, the position, spacing and angle of the sprue block 3 can be flexibly adjusted to adapt to annular stator plastic-coated parts of different sizes and different sprue residual positions. There is no need to equip plastic-coated parts of different specifications with separate sprue devices, which reduces production input and improves the practicality and versatility of the device.

[0035] Stable structure and long service life: All components of the device adopt a robust connection method. Key components such as support leg 5 and drain block 3 are made of high-strength, vibration-resistant, and wear-resistant materials, which can not only ensure the structural stability during operation, but also reduce the wear of components and extend the service life of the device. At the same time, the anti-slip protrusion 16 and rubber adjusting ball not only improve the stability of limit and adjustment, but also avoid damage to the surface of the plastic-coated parts, thus protecting product quality.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
