Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing, specifically to a stator press-fitting machine, used to press a motor stator into a motor base to form a motor assembly. Background Technology

[0002] In existing industrial applications, motor stators are press-fitted onto a fixed platform. This method has the following drawbacks: First, the fixed platform is a flat plane, and large press-fitting machines can easily damage the copper wires on the stator, leading to quality issues. Second, after press-fitting on the fixed platform, the entire motor assembly needs to be lifted, flipped, and moved to the next production station using lifting equipment. However, there is a risk of the lifted motor assembly falling, causing a safety accident. Third, the motor assembly is large and heavy, resulting in high labor intensity for workers.

[0003] Previous solutions to the above problems were as follows: First, during stator pressing, operators would observe whether there was any squeezing of the copper wires. If there was a risk, the copper wires would be avoided. However, manual identification could not handle the situation in a timely manner, and there were safety risks when personnel were involved. Second, a suspension arm was added to assist workers in flipping and suspending the motor assembly. However, this method was labor-intensive, not conducive to long-term production, and affected production efficiency. Third, multiple people assisted in the operation to complete the production work of this process simultaneously. However, this method would increase labor costs and was not conducive to cost reduction and efficiency improvement in production. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an improved stator pressing machine, which can prevent the copper wires of the motor stator from being damaged during the pressing process, ensure product quality, and also eliminate the need for manual assistance in flipping the motor components, thereby improving production efficiency.

[0005] This utility model provides a stator pressing machine, comprising: a frame having an upper part and a base; a lifting mechanism disposed on the upper part of the frame and configured to move vertically; a pressing head connected to the lifting mechanism and driven by the lifting mechanism to move vertically, for pressing a motor stator into a motor base to form a motor assembly; and a support platform disposed on the base of the frame and positioned below the pressing head, the support platform having an open upper receiving space and a support seat surrounding the receiving space, the support seat being configured to position and support the motor base so that the motor base is held vertically, wherein the receiving space is configured to suspend the end of the motor stator during pressing.

[0006] In this way, the support platform of the stator press machine of this utility model is hollow and has an open upper end for accommodating space. When the motor stator is press-fitted, the motor stator is in a suspended working state, which avoids the ends of the motor stator (especially the copper wires) being squeezed and damaged, thus ensuring product quality.

[0007] According to an exemplary embodiment of this application, the stator press-fitting machine further includes a flipping mechanism configured to flip the support platform from a first state to a second state, wherein in the first state the support platform is horizontal such that the central axis of the motor assembly located on the support platform is vertical, and in the second state the support platform is vertical such that the central axis of the motor assembly located on the support platform is horizontal.

[0008] In this way, the stator press-fitting machine of this invention can flip the support platform from a horizontal state to a vertical state through the flipping mechanism, so that the central axis of the motor assembly changes from vertical to horizontal, reducing the complexity of the motor assembly during repositioning, improving the automation and efficiency of the production line, and reducing the safety risks caused by manual operation.

[0009] According to an exemplary embodiment of this application, the flipping mechanism includes: a flipping actuator for providing a driving force to flip the support platform; a vertical wall connected perpendicularly to one side of the support platform, wherein in a first state the vertical wall extends vertically upward and in a second state the vertical wall extends horizontally to carry the flipped motor assembly; and a pivot located at one side of the support platform so that the support platform can flip about the pivot when the support platform is driven by the flipping actuator.

[0010] In this way, the stator press-fitting machine of this invention utilizes the vertical wall to ensure the safety and stability of the motor assembly during the flipping process, while the pivot design enables precise flipping action.

[0011] According to an exemplary embodiment of this application, the vertical wall of the flipping mechanism includes a frame structure and a plurality of drive rollers mounted in the frame structure.

[0012] In this way, the flipped motor assembly can be easily transported to the next workstation by the rolling of the drive rollers.

[0013] According to an exemplary embodiment of this application, the stator press-fitting machine further includes a horizontal moving mechanism, which is configured to: in the first state, enable the support platform and the motor assembly to move along the horizontal moving direction on the frame base to a flipping station, in which the motor assembly is attached to the vertical wall.

[0014] In this way, the press-fitted motor assembly can be moved and pressed against the vertical wall using a horizontal moving mechanism. This facilitates the smooth operation of the flipping action and avoids the risk of the motor assembly wobbling and rolling off during the flipping process.

[0015] According to an exemplary embodiment of this application, the horizontal movement mechanism includes: a horizontal movement actuator for providing a driving force to drive the support platform to move horizontally; a base track formed above the frame base; and a slider mechanism formed below the support platform, the slider mechanism being driven by the horizontal movement actuator, the slider mechanism having a groove that matches the shape of the base track to be able to move horizontally along the base track, thereby driving the support platform to move horizontally.

[0016] In this way, the base track matches the slide groove of the slider mechanism under the support platform, ensuring the smoothness and stability of the support platform when moving horizontally.

[0017] According to an exemplary embodiment of this application, the support base is annular and includes a stepped annular stop, and the stator press-fitting machine further includes a plurality of washer rings, each of the washer rings having an outer peripheral annular profile complementary to the annular stop to be selectively received in the annular stop of the support base, and the inner peripheral diameters of the plurality of washer rings being different from each other to be adapted to position and support different models of motor bases.

[0018] In this way, by using multiple washers with different inner circumference diameters, the stator press-fitting machine of this application can adapt to the positioning and support requirements of different types of motor bases, realizing the multi-purpose and flexible production of the stator press-fitting machine, reducing the adjustment time of the production line and lowering the production cost.

[0019] According to an exemplary embodiment of this application, the frame base includes: a base body; and a flipping mechanism connecting plate, the flipping mechanism connecting plate being fixedly mounted above the base body, the flipping mechanism connecting plate being quadrilateral in shape; wherein, the base track includes a first guide rail and a second guide rail, the first guide rail and the second guide rail being parallel to each other and respectively arranged close to two opposite sides of the flipping mechanism connecting plate; wherein, the support platform is a quadrilateral plate structure located above the flipping mechanism connecting plate, the accommodating space on the support platform is formed by a central cylindrical through hole in the plate structure, and the slider mechanism includes a plurality of sliders, the first guide rail and the second guide rail each corresponding to at least one of the sliders; and wherein, the base body has a hollow structure in the middle, the flipping actuator being able to pass through the hollow structure and connect to the flipping mechanism connecting plate to drive the flipping mechanism connecting plate and the support platform to flip.

[0020] In this way, the quadrilateral design of the base body and the flipping mechanism connecting plate, together with the arrangement of the first and second guide rails, makes the flipping and movement of the support platform more stable. At the same time, the use of the hollow structure provides space for the flipping actuator, realizing the efficient integration of the flipping mechanism and the frame base, and improving the overall performance of the stator press machine.

[0021] According to an exemplary embodiment of this application, the horizontal movement actuator is a pneumatic actuator, which includes: a cylinder mounted on the frame base, the cylinder including a cylinder barrel, a cylinder piston, and a cylinder piston rod; a cylinder connector, one end of which is connected to the cylinder piston rod and the other end of which is connected to the slider mechanism; and a manual valve connected to the cylinder for controlling the operation of the cylinder.

[0022] In this way, a pneumatic actuator is used as the horizontal movement actuator. Through the combination of cylinders, cylinder connectors and manual valves, the support platform can be moved quickly and smoothly. At the same time, the pneumatic actuator is easy to control and responds quickly, which reduces the maintenance cost of the stator press and improves the safety of operation.

[0023] According to an exemplary embodiment of this application, the tilting actuator is a hydraulic actuator, which includes: a hydraulic cylinder mounted on the frame base, the hydraulic cylinder including a hydraulic cylinder barrel, a hydraulic piston and a hydraulic piston rod; and a hydraulic cylinder connector, one end of which is connected to the hydraulic piston rod and the other end of which is configured to drive the support platform to tilt.

[0024] In this way, the tilting actuator adopts a hydraulic actuator, which not only ensures the strength and smoothness of the tilting action, but also makes the tilting of the support platform more efficient due to the high torque characteristics of the hydraulic system. This improves the tilting speed and accuracy of the stator press machine, and enhances its stability and durability.

[0025] The stator press-fitting machine of this utility model can achieve the following beneficial technical effects.

[0026] First, the stator pressing machine of this utility model adopts a hollow support platform. When the motor stator is pressed, the motor stator is in a suspended working state, which avoids the risk of the copper wire in the motor stator being squeezed and damaged.

[0027] Secondly, the stator pressing machine of this utility model uses a large cylinder as a horizontal moving actuator, which can move the pressed motor assembly to fit against the vertical wall, which is conducive to the flipping action and avoids the risk of the wobbling motor assembly rolling and slipping when flipping.

[0028] Third, the stator press-fitting machine of this utility model adopts a flipping mechanism, which can flip the vertically placed motor assembly as a whole, so that the motor assembly is flipped to a horizontal position, thereby facilitating subsequent assembly line production operations and reducing the labor intensity of workers.

[0084] To make the objectives, technical solutions, and advantages of this utility model clearer, the following embodiments are provided to further illustrate the utility model in detail. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the utility model or its application or use. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model. The nouns and pronouns referring to persons in this patent application are not limited to specific genders.

[0085] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0086] First, refer to this application. Figures 1 to 3 The diagram shows a schematic perspective view of a stator press-fitting machine according to an exemplary embodiment of the present invention, illustrating three different states. The stator press-fitting machine of the present invention mainly includes a frame 100, a lifting mechanism 200, and a press-fitting head 300.

[0087] like Figure 1 As shown, the rack 100 has a rack upper portion 110 and a rack base 120. (As...) Figure 3 As shown, the lifting mechanism 200 is located on the upper part 110 of the frame and configured to move vertically. The lifting mechanism 200 can be a hydraulic cylinder. Figure 3 As shown, the pressing head 300 is connected to the lifting mechanism 200 and is driven by the lifting mechanism 200 to move vertically, for pressing the motor stator 10 into the motor base 20 to form the motor assembly 30. Figure 4 (As shown in the image). Figure 3 As shown, the support platform 400 is mounted on the frame base 120 and positioned below the pressing head 300, as... Figure 5As shown, the support platform 400 has an upper open receiving space 420 and a support base 410 surrounding the receiving space 420. The support base 410 is configured to position and support the motor base 20 so that the motor base 20 can be held vertically. It is understood that the support base 410 may be configured to directly support the motor base 20 or to support the motor base 20 via a washer 40 (described in detail below). The receiving space 420 is configured to suspend the ends of the motor stator 10 during press-fitting to prevent damage to the ends of the motor stator, especially the copper wires, during the press-fitting process, thereby ensuring product quality.

[0088] Reference Figure 4 The stator press may also include a tilting mechanism 500, configured to tilt the support platform 400 from... Figure 3 The first state shown is flipped to Figure 4 The second state shown is as follows: in the first state, the support platform 400 is horizontal, making the central axis of the motor assembly 30 located on the support platform 400 vertical; and in the second state, the support platform 400 is vertical, making the central axis of the motor assembly 30 located on the support platform 400 horizontal.

[0089] Reference Figure 4 The main components of the flipping mechanism 500 can be clearly understood. The flipping mechanism 500 mainly includes: a flipping actuator 510, which provides the driving force for flipping the support platform 400; a vertical wall 520, which is vertically connected to one side of the support platform 400. In a first state, the vertical wall 520 extends vertically upward, and in a second state, the vertical wall 520 extends horizontally to carry the flipped motor assembly 30; and a pivot 530, located on one side of the support platform 400, so that when the support platform 400 is driven by the flipping actuator 510, the support platform can flip around the pivot 530.

[0090] The tilting actuator 510 can be a hydraulic actuator, which includes: a hydraulic cylinder (not shown), which is mounted on the frame base 120 and includes a hydraulic cylinder barrel, a hydraulic piston and a hydraulic piston rod; and a hydraulic cylinder connector, one end of which is connected to the hydraulic piston rod and the other end of which is configured to drive the support platform 400 to tilt. Figure 4The specific structure of the hydraulic cylinder, hydraulic piston, and hydraulic piston rod is not shown; only the portion used to lift the support platform 400, i.e., a part of the tilting actuator 510, is shown. Those skilled in the art can implement the specific configuration of the hydraulic actuator with appropriate configuration. The hydraulic cylinder can be placed inside the frame base 120, and the hydraulic piston rod can drive the hydraulic cylinder connector, thereby causing the support platform 400 to tilt.

[0091] Reference Figure 4 The vertical wall 520 of the flipping mechanism 500 may include a frame structure 521 and a plurality of drive rollers 522 mounted in the frame structure 521. By the rolling of the drive rollers 522, the flipped motor assembly 30 can be easily transported to the next station.

[0092] Reference Figures 5 to 7 The stator press-fitting machine also includes a horizontal moving mechanism 600, which is configured such that, in the first state, the support platform 400 and the motor assembly 30 can move along the horizontal moving direction on the frame base to reach the flipping station. In the flipping station, the motor assembly 30 is attached to the vertical wall 520 (see reference). Figure 3 ).

[0093] Reference Figure 8 The horizontal movement mechanism 600 includes: a horizontal movement actuator 610 for providing driving force to drive the support platform 400 to move horizontally; a base track 620 formed above the frame base; and a slider mechanism 630 formed below the support platform 400, the slider mechanism 630 being connected to the horizontal movement actuator 610 and thus driven by the horizontal movement actuator 610, the slider mechanism 630 having a groove that matches the shape of the base track 620 so as to be able to move horizontally along the base track 620, thereby driving the support platform 400 to move horizontally.

[0094] Reference Figure 5 and Figure 9 The support base 410 may be annular and may include a stepped annular stop 411. The annular stop 411 includes an annular stop step surface 412 and an annular stop inner circumferential surface 413. The inner diameter of the annular stop inner circumferential surface 413 may be, for example, 400 mm. The diameter of the cylindrical through hole below the annular stop step surface 412 may be, for example, 380 mm. The stator press-fitting machine may also include multiple gaskets 40 ( Figures 10 to 13 (As shown), a plurality of washers 40 each have an outer peripheral annular profile complementary to the annular stop 411 to be selectively received in the annular stop 411 of the support 410, and the inner peripheral diameters of the plurality of washers 40 are different from each other to be suitable for positioning and supporting different types of motor bases 20. Figure 10 and Figure 11 The first type of washer ring is shown in the figure, while Figure 12 and Figure 13 The diagram illustrates a second type of washer. Clearly, the inner circumferential diameter of the first type of washer is larger than that of the second type. Therefore, the outer diameter of the motor base that the first type of washer can support and position can be smaller than the outer diameter of the motor base that the second type of washer can support and position. For example, the inner diameters of multiple washers can be, for example, 290 mm, 325 mm, or 345 mm, and the outer diameter can all be 399 mm. (See reference...) Figure 10 The washer 40 may include a washer step surface 41 that mates with the stepped annular stop 411 of the support 410. The washer 40 may also include a plurality of washer through holes 42 and a plurality of washer grooves 43. The plurality of washer through holes 42 and the plurality of washer grooves 43 are evenly distributed on the washer 40. The arrangement of the plurality of washer through holes 42 and the plurality of washer grooves 43 can reduce the weight of the washer 40 and facilitate the positioning and installation of the washer 40 on the stepped annular stop 411.

[0095] Reference Figure 8 The frame base 120 includes: a base body 121; and a flipping mechanism connecting plate 122, which is fixedly mounted above the base body 121 and is quadrilateral in shape. The base track 620 includes a first guide rail 621 and a second guide rail 622, which are parallel to each other and arranged close to two opposite sides of the flipping mechanism connecting plate 122. The support platform 400 is a quadrilateral plate structure located above the flipping mechanism connecting plate 122. The receiving space 420 on the support platform 400 is formed by a cylindrical through-hole in the plate structure, the diameter of which may be, for example, 380 mm. The slider mechanism 630 includes a plurality of sliders 631, and each of the first guide rail 621 and the second guide rail 622 corresponds to at least one slider. (See reference...) Figure 6 The support platform 400 has multiple platform connection parts 414, specifically four platform connection parts 414, for connection with four sliders 631 via, for example, threaded connectors.

[0096] Reference Figure 7 The base body 121 has a hollow structure 123 in the middle. The flipping actuator 510 can pass through the hollow structure 123 and connect with the corresponding auxiliary plate connecting part 124 on the flipping mechanism connecting plate 122 to drive the flipping mechanism connecting plate 122 and the support platform 400 to flip. (Refer to...) Figure 5 As can be seen, the rack base 120 may also include a first baffle 125 and a second baffle 126 to provide protection.

[0097] Reference Figure 8The horizontal moving actuator 610 can be a pneumatic actuator, which includes a cylinder 611, a cylinder connector 612, and a manual valve 613. The cylinder 611 is mounted on the frame base 120 and located on one side of the second guide rail 622. The cylinder 611 includes a cylinder barrel, a cylinder piston, and a cylinder piston rod, and its stroke is, for example, 100 mm. One end of the cylinder connector 612 is connected to the cylinder piston rod, and the other end is connected to the slider mechanism 630. The manual valve 613 is connected to the cylinder 611 to control its operation.

[0098] The stator press-fitting machine of this invention features a rotatable, movable, and hollow support platform design, which enables optimized solutions.

[0099] First, the support platform has an open upper cavity. The size of this cavity is sufficient to prevent the motor base from falling off while ensuring the motor stator is suspended within it. This protects the copper conductors of the stator from crushing or damage, thus guaranteeing product quality. Simultaneously, it incorporates gaskets of varying inner diameters (ring-shaped rings). When processing different types of motors, simply changing the gaskets of different inner diameters enables flexible stator press-fitting production, improving production efficiency.

[0100] Secondly, the stator press-fitting machine may include a horizontal moving mechanism. This mechanism uses a large cylinder to move the support platform that carries the entire motor assembly horizontally. This ensures that after the stator is press-fitted, the motor assembly can fit against the vertical wall of the flipping mechanism, so that the motor assembly can be stable and not slip when flipping, thus ensuring the safety of production.

[0101] Third, the stator press-fitting machine may include a flipping mechanism, which adopts a hydraulic actuator to flip the vertical motor assembly from the vertical direction to the horizontal direction, facilitating subsequent assembly line production. This mechanism not only ensures the stability of the flipping but also takes into account the flipping efficiency of the hydraulic actuator, thereby improving production efficiency.

[0102] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
