Description

Technical Field

[0001] This invention relates to the field of stator core assembly technology, specifically a stator assembly equipment. Background Technology

[0002] Segmented stators have become the mainstream structure for high-end motors. Assembling the stator into a circle is an indispensable process in motor assembly. It is the core link connecting the processing of sector-shaped blocks with the overall forming of the stator. Through precise positioning, the scattered blocks are aggregated into a concentric and rounded ring. In fields such as new energy vehicle drive motors and industrial high-power motors, it is necessary not only to ensure the stability of the mechanical structure, but also to adapt to the mass production needs of automated production lines, ensure the consistency of the performance of each motor, improve the material utilization rate and processing flexibility of segmented stators, and achieve the goals of high efficiency and lightweight in high-end motors.

[0003] Existing process solutions mostly use servo mechanisms, which have complex equipment components, are difficult to process, and have excessively high costs for assembly mechanisms. Furthermore, all modular installation mechanisms use dovetail groove structures, which affects work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a stator assembly equipment to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The stator assembly circle assembly equipment includes a platform, on which a sliding component is provided. Two safety light curtains are symmetrically installed on the top of the platform near the sliding component. Two mounting blocks are installed on the platform, and each mounting block is equipped with a buffer. A limit plate is installed on the sliding component, positioned between the two buffers. A receiving component is provided below the sliding component. An assembly circle component is provided on top of the sliding component. Multiple clamping components are arranged in a circular array within the assembly circle component. The bottom of the component is equipped with a side-pushing assembly, and the platform is equipped with a pressing assembly. The pressing assembly is located above the receiving assembly. When the stator is assembled into a circle, multiple iron core assembly blocks are placed into the circle assembly in its initial position. The sliding assembly moves the circle assembly to directly above the receiving assembly. At this time, the side-pushing assembly drives multiple clamping assemblies to retract inward through the circle assembly to make the multiple iron core assembly blocks cooperate with each other into a circle. Then, the pressing assembly presses the multiple iron core assembly blocks that have cooperated into a circle into the receiving assembly for processing, thereby reducing equipment costs, improving operational stability, and increasing work efficiency.

[0006] As a preferred technical solution, the sliding assembly includes a slide rail pad, a slide rail, a concave slider, a base plate, a dovetail groove, a fixing plate, a material ejection cylinder, and a connecting block; Two slide rail blocks are installed parallel to each other on the platform. Each slide rail block is equipped with a slide rail, and each slide rail is equipped with multiple concave sliders. A base plate is installed on the top of each concave slider, and a dovetail groove is formed on the base plate. A fixing plate is installed on the platform, and a material ejection cylinder is installed on the fixing plate. The output end of the material ejection cylinder is connected to the base plate through a connecting block. When multiple iron core assembly blocks are placed into the round assembly, the concave sliders on the slide rails drive the base plate to move closer to the receiving assembly. When the base plate moves to the designated position, it stops moving. After processing is completed, the material ejection cylinder drives the base plate back to the initial position, thereby realizing cyclic feeding.

[0007] As a preferred technical solution, the receiving assembly includes a lifting and locking cylinder, a sliding sleeve, a lower top column, a top block, a squirrel cage, a welding hole, and a stator slot; A lifting and locking cylinder is installed at the bottom of the platform panel. The output end of the lifting and locking cylinder passes through the platform panel. A sliding sleeve is installed on the top of the platform panel directly above the lifting and locking cylinder. Multiple locking blocks are installed on the inner wall of the sliding sleeve. A lower top column is slidably installed inside the sliding sleeve. A slot is opened on the side wall of the lower top column. The locking blocks are slidably installed in the slot. A top block is installed at the bottom of the lower top column. A squirrel cage is installed at the top of the lower top column. Multiple welding holes are opened on the circumference of the squirrel cage. Multiple stator slots are opened on the inner wall of the squirrel cage. After multiple iron core assembly blocks are assembled into a circle, the lifting and locking cylinder pushes the top block to move. The top block causes the lower top column to lift the squirrel cage. Then, the pressing assembly presses the assembled iron core assembly blocks into the squirrel cage. The locking blocks are locked in the slots to prevent the lower top column from deflecting due to pressure when the iron core assembly blocks enter the squirrel cage. This facilitates the positioning of the welding direction and the positioning of the stator exiting the squirrel cage.

[0008] As a preferred technical solution, the circular assembly includes a support column, a mounting plate, a mounting hole, a rotating disk, an arc-shaped inclined groove, an annular fixed disk, a slide rail, a slide rail hole, a pressure plate, a limiting block, a protective cover, a bearing, and a bearing support. Four support columns are installed on the base plate, and mounting plates are installed on the top of the four support columns. Mounting holes are provided on the mounting plates, and an annular fixing plate is installed directly above the mounting holes. A protective cover is installed on the top of the annular fixing plate. Multiple slide rails are provided on the annular fixing plate, and each slide rail has a slide rail hole. A bearing support is installed at the bottom of the annular fixing plate, and a bearing is installed on the bearing. A rotating disk is installed on the bearing, and multiple arc-shaped inclined grooves are evenly provided on the rotating disk. Limit blocks are installed at the bottom of the base plate. When multiple iron core assembly blocks are placed into the annular fixing plate, the side-pushing component drives the rotating disk at the bottom of the annular fixing plate to rotate. The rotation of the rotating disk causes multiple clamping components to move towards the rotation center on the annular fixing plate, pushing the multiple iron core assembly blocks inward to form a circle. By providing a protective cover on the annular fixing plate, contact between the stator bridge and the equipment is reduced, thereby reducing the risk of scratching the bridge wire.

[0009] As a preferred technical solution, the clamping assembly includes a slider, a positioning block, a spring, a pressure block, and a sliding column; A slider is slidably installed in the slide rail, and a positioning block is installed on the slider. Two square holes are symmetrically opened on the positioning block, and a pressure block is slidably installed in the square holes. A spring is installed at the bottom of the pressure block, and a sliding column is installed at the bottom of the slider. The other end of the sliding column passes through the slide rail hole and is slidably installed in the arc-shaped inclined groove. When the iron core assembly is clamped onto the positioning block, the spring causes the pressure block to press against the iron core assembly. When the side-push cylinder pushes the rotating disk to rotate, the sliding column in the arc-shaped inclined groove and the slide rail hole drives the slider to slide on the slide rail, thereby splicing multiple iron core assemblies into a circle. After the iron core assembly is clamped in place, the spring presses against the pressure block, making the splicing and clamping method simple and eliminating the risk of the iron core assembly falling.

[0010] As a preferred technical solution, the positioning block is divided into a dovetail groove positioning block and a straight groove positioning block. The dovetail groove structure is used for positioning in the circumferential direction of the iron core, while the straight groove structure only participates in guidance during operation, making clamping more convenient and faster.

[0011] As a preferred technical solution, the side thrust assembly includes a fixed frame, a side thrust cylinder, a floating joint, and a rotating shaft; A fixed frame is installed on the side of the base plate near the slide rail. A side-push cylinder is installed on the fixed frame. A floating joint is installed at the output end of the side-push cylinder. A rotating shaft is installed on the floating joint. The other end of the rotating shaft is slidably installed in the arc-shaped inclined groove. When the iron core assembly block is clamped, the side-push cylinder drives the rotating shaft on the floating joint to extend forward. Then, the rotating shaft slides in the arc-shaped inclined groove to drive the rotating disk to rotate. The combined structure of the rotating shaft and the arc-shaped inclined groove is similar to a force-saving lever, which can effectively reduce the thrust required by the side-push cylinder.

[0012] As a preferred technical solution, the press assembly includes a guide post, a safety spring, a sliding plate, a press head fixing block, a stator press head, an anti-rotation block, a loading plate, and a press cylinder; Four guide pillars are installed on the platform, each with a safety spring. A sliding plate is slidably mounted on the four guide pillars, and a pressure head fixing block is installed at the bottom of the sliding plate. A stator pressure head is installed on the pressure head fixing block, and multiple anti-rotation blocks are installed in a circular array on the side wall of the stator pressure head. A loading plate is installed on the top of the four guide pillars, and a pressing cylinder is installed on the top of the loading plate. The output end of the pressing cylinder passes through the loading plate and is fixedly connected to the sliding plate. After the iron core assembly blocks are assembled, the pressing cylinder drives the sliding plate to move downward along the guide pillars. The sliding plate drives the stator pressure head on the pressure head fixing block to move downward, aligning the multiple anti-rotation blocks with the multiple iron core assembly blocks one by one. This achieves iron core assembly without rotation, pressing it into the squirrel cage. The four guide pillars and safety springs can protect the equipment from the safety risk of falling due to its own weight in the event of an accidental interruption of the pressing cylinder's air supply.

[0013] As a preferred technical solution, the safety light curtain is electrically connected to the slide rail, the material ejection cylinder, the lifting and locking cylinder, the side push cylinder, and the pressing cylinder.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This application uses a side-push cylinder to drive the rotating shaft on the floating joint to extend forward, and then the rotating shaft slides in the arc-shaped inclined groove to drive the rotating disk to rotate. The combined structure of the rotating shaft and the arc-shaped inclined groove is similar to a force-saving lever, which can effectively reduce the thrust required by the side-push cylinder. The rotation of the rotating disk causes multiple clamping components to move towards the rotation center on the annular fixed disk, and the multiple clamping components push multiple iron core assembly blocks to retract inward to form a circle. By setting a protective cover on the annular fixed disk, the contact between the stator bridge and the equipment is reduced, thereby reducing the risk of scratching the bridge line.

[0015] 2. In this application, when clamping the iron core assembly blocks, the rotating disk is driven to rotate by the side-push cylinder. The sliding column in the arc-shaped inclined groove and the slide hole drives the slider to slide on the slide, so that multiple iron core assembly blocks are spliced ​​into a circle. After the iron core assembly blocks are clamped in place, the pressure block is held by the spring. The splicing and clamping method is simple and there is no risk of the iron core assembly blocks falling. Then, the positioning block with the dovetail groove structure is used for the circumferential positioning of the iron core, and the positioning block with the straight groove structure participates in the guidance during the operation, making the clamping more convenient and faster.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example: Figures 1-2 As shown, the present invention provides a technical solution for a stator assembly circle assembly device. This device includes a platform 1, on which a sliding assembly 2 is mounted. Two safety light curtains 101 are symmetrically installed on the top of the platform 1 near the sliding assembly 2. Two mounting blocks 701 are mounted on the platform 1, each with a buffer 702. A limiting plate 703 is mounted on the sliding assembly 2, positioned between the two buffers 702. A receiving assembly 3 is located below the sliding assembly 2, and an assembly circle assembly 4 is located on top of the sliding assembly 2. Multiple clamping components are arranged in a circular array within the assembly circle assembly 4. 5. A side-pushing component 6 is provided at the bottom of the circular assembly 4, and a pressing component 8 is provided on the platform 1. The pressing component 8 is located above the receiving component 3. When the stator is assembled into a circular shape, multiple iron core assembly blocks are placed into the circular assembly 4 in its initial position. The sliding component 2 drives the circular assembly 4 to move directly above the receiving component 3. At this time, the side-pushing component 6 drives multiple clamping components 5 to retract inward through the circular assembly 4 to make the multiple iron core assembly blocks cooperate with each other into a circle. Then, the pressing component 8 presses the multiple iron core assembly blocks that have cooperated into a circle into the receiving component 3 for processing, thereby reducing equipment costs, improving operational stability and increasing work efficiency.

[0020] like Figures 1-2 As shown, the sliding assembly 2 includes a slide rail pad 201, a slide rail 202, a concave slider 203, a base plate 204, a dovetail groove 205, a fixing plate 206, a material ejection cylinder 207, and a connecting block 208. Two slide rail blocks 201 are installed in parallel on the table panel 1. Each slide rail block 201 is equipped with a slide rail 202. Multiple concave sliders 203 are installed on each slide rail. A base plate 204 is installed on the top of each concave slider 203. A dovetail groove 205 is opened on the base plate 204. A fixing plate 206 is installed on the table panel 1. A material ejection cylinder 207 is installed on the fixing plate 206. The output end of the material ejection cylinder 207 is connected to the base plate 204 through a connecting block 208. When multiple iron core assembly blocks are placed into the round assembly 4, the concave sliders 203 on the slide rail 202 drive the base plate 204 to move closer to the receiving assembly 3. When the base plate 204 moves to the designated position, it stops moving. After processing is completed, the material ejection cylinder 207 drives the base plate 204 back to the initial position, thereby realizing cyclic feeding.

[0021] like Figures 2-4 and Figure 9 As shown, the receiving assembly 3 includes a lifting and locking cylinder 301, a sliding sleeve 302, a lower top column 303, a top block 304, a squirrel cage 305, a welding hole 3051, and a stator slot 3052; A lifting and locking cylinder 301 is installed at the bottom of the platform 1. The output end of the lifting and locking cylinder 301 passes through the platform 1. A sliding sleeve 302 is installed on the top of the platform 1 directly above the lifting and locking cylinder 301. Multiple locking blocks 3021 are installed on the inner wall of the sliding sleeve 302. A lower top column 303 is slidably installed inside the sliding sleeve 302. A slot 3031 is opened on the side wall of the lower top column 303. The locking blocks 3021 are slidably installed in the slot 3031. A top block 304 is installed at the bottom of the lower top column 303. A mouse cage 305 is installed on the top of the lower top column 303. The mouse cage 305 has a circumference opening Multiple welding holes 3051 are provided, and multiple stator slots 3052 are opened on the inner wall of the squirrel cage 305. After the multiple iron core assembly blocks are assembled into a circle, the lifting and locking cylinder 301 pushes the top block 304 to move. The top block 304 causes the lower top column 303 to drive the squirrel cage 305 to rise. Then the pressing assembly 8 presses the assembled iron core assembly blocks into the squirrel cage 305. The locking block 3021 is locked in the locking slot 3031 to prevent the lower top column 303 from deflecting due to pressure when the iron core assembly blocks enter the squirrel cage 305. This facilitates the positioning of the welding direction and the positioning of the stator exiting the squirrel cage 305.

[0022] like Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the circular assembly 4 includes a support column 401, a mounting plate 402, a mounting hole 403, a rotating disk 404, an arc-shaped inclined groove 405, an annular fixing disk 406, a slide 4061, a slide hole 4062, a pressure plate 407, a limiting block 408, a protective cover 409, a bearing 410, and a bearing support 411; Four support columns 401 are installed on the base plate 204. A mounting plate 402 is installed on top of each support column 401. Mounting holes 403 are provided on the mounting plate 402. An annular fixing plate 406 is installed directly above the mounting holes 403. A protective cover 409 is installed on top of the annular fixing plate 406. Multiple slide rails 4061 are provided on the annular fixing plate 406, and slide rail holes 4062 are provided on each slide rail 4061. A bearing support 411 is installed at the bottom of the annular fixing plate 406. A bearing 410 is installed on the bearing support 411, and a rotating disk 404 is installed on the bearing 410. Multiple arc-shaped inclined grooves 405 are evenly provided on the rotating disk 404, and limit blocks 408 are installed at the bottom of the base plate 204. When multiple iron core assembly blocks are placed into the annular fixed disk 406, the side push component 6 drives the rotating disk 404 at the bottom of the annular fixed disk 406 to rotate. The rotation of the rotating disk 404 causes multiple clamping components 5 to move towards the rotation center on the annular fixed disk 406, so that the multiple clamping components 5 push the multiple iron core assembly blocks to retract inward to form a circle. By setting a protective cover 409 on the annular fixed disk 406, the contact between the stator bridge and the equipment is reduced, thereby reducing the risk of scratching the bridge line.

[0023] like Figure 7 As shown, the clamping assembly 5 includes a slider 501, a positioning block 502, a spring 503, a pressure block 504, and a sliding column 505; A slider 501 is slidably installed inside the slide rail 4061. A positioning block 502 is installed on the slider 501. Two square holes are symmetrically opened on the positioning block 502. A pressure block 504 is slidably installed inside the square holes. A spring 503 is installed at the bottom of the pressure block 504. A sliding post 505 is installed at the bottom of the slider 501. The other end of the sliding post 505 passes through the slide rail hole 4062 and is slidably installed in the arc-shaped inclined groove 405. When the iron core assembly is clamped onto the positioning block 502... Then, the spring 503 causes the pressure block 504 to press against the iron core assembly block. When the side-push cylinder 602 pushes the rotating disk 404 to rotate, the sliding column 505 in the arc-shaped inclined groove 405 and the slide hole 4062 drives the slider 501 to slide on the slide 4061, so that multiple iron core assembly blocks are spliced ​​into a circle. After the iron core assembly block is clamped in place, the spring 503 presses against the pressure block 504, so that the splicing and clamping method is simple and there is no risk of the iron core assembly block falling.

[0024] The positioning block 502 is divided into dovetail groove positioning block and straight groove positioning block. The dovetail groove structure is used for positioning in the circumferential direction of the iron core, while the straight groove structure only participates in guidance during operation, making clamping more convenient and faster.

[0025] like Figures 1-3 and Figure 6 As shown, the side thrust assembly 6 includes a fixed frame 601, a side thrust cylinder 602, a floating joint 603, and a rotating shaft 605; A fixed frame 601 is installed on the side of the base plate 204 near the slide rail 202. A side-push cylinder 602 is installed on the fixed frame 601. A floating joint 603 is installed at the output end of the side-push cylinder 602. A rotating shaft 605 is installed on the floating joint 603. The other end of the rotating shaft 605 is slidably installed in the arc-shaped inclined groove 405. When the iron core assembly block is clamped, the side-push cylinder 602 drives the rotating shaft 605 on the floating joint 603 to extend forward. Then, the rotating shaft 605 slides in the arc-shaped inclined groove 405 to drive the rotating disk 404 to rotate. The combined structure of the rotating shaft 605 and the arc-shaped inclined groove 405 is similar to a force-saving lever, which can effectively reduce the thrust required by the side-push cylinder 602.

[0026] like Figures 1-3 As shown, the press assembly 8 includes a guide post 801, a safety spring 802, a sliding plate 803, a press head fixing block 804, a stator press head 805, an anti-rotation block 8051, a loading plate 806, and a press cylinder 807. Four guide pillars 801 are installed on the platform 1. Each of the four guide pillars 801 is fitted with a safety spring 802. A sliding plate 803 is slidably installed on the four guide pillars 801. A pressure head fixing block 804 is installed at the bottom of the sliding plate 803. A stator pressure head 805 is installed on the pressure head fixing block 804. Multiple anti-rotation blocks 8051 are installed in a circular array on the side wall of the stator pressure head 805. A loading plate 806 is installed on the top of the four guide pillars 801. A pressing cylinder 807 is installed on the top of the loading plate 806. The output end of the pressing cylinder 807 passes through the loading plate. Plate 806 is fixedly connected to slide plate 803. After the iron core assembly blocks are assembled, pressing cylinder 807 drives slide plate 803 to move downward along guide post 801. Slide plate 803 drives stator pressing head 805 on pressing head fixing block 804 to move downward, so that multiple anti-rotation blocks 8051 correspond one-to-one with multiple iron core assembly blocks, thereby realizing the iron core assembly without rotation and pressing into squirrel cage 305. The four guide posts 801 plus safety spring 802 can protect the equipment from the safety risk caused by its own weight falling when pressing cylinder 807 is accidentally cut off.

[0027] The safety light curtain 101 is electrically connected to the slide rail 202, the ejector cylinder 207, the lifting and locking cylinder 301, the side push cylinder 602, and the pressing cylinder 807.

[0028] Working principle of the invention: When assembling the stator into a circle, multiple iron core assembly blocks are placed into the circle assembly 4 in its initial position. The sliding assembly 2 moves the circle assembly 4 directly above the receiving assembly 3. At this time, the side pushing assembly 6 drives multiple clamping assemblies 5 to retract inward through the circle assembly 4, making the multiple iron core assembly blocks cooperate to form a circle. Then, the pressing assembly 8 presses the multiple iron core assembly blocks that have cooperated to form a circle into the receiving assembly 3 for processing, thereby reducing equipment costs, improving operational stability and increasing work efficiency.

[0029] After multiple iron core assembly blocks are placed in the round assembly 4, the concave slider 203 on the slide rail 202 drives the base plate 204 to move closer to the receiving assembly 3. When the base plate 204 moves to the designated position, it stops moving. After processing is completed, the ejector cylinder 207 drives the base plate 204 back to the initial position, thereby realizing cyclic feeding.

[0030] After multiple iron core assembly blocks are assembled into a circle, the lifting and locking cylinder 301 pushes the top block 304 to move. The top block 304 causes the lower top column 303 to lift the squirrel cage 305. Then, the pressing assembly 8 presses the assembled iron core assembly blocks into the squirrel cage 305. The locking block 3021 is locked in the locking groove 3031 to prevent the lower top column 303 from deflecting due to pressure when the iron core assembly blocks enter the squirrel cage 305. This facilitates the positioning of the welding direction and the positioning of the stator exiting the squirrel cage 305.

[0031] After multiple iron core assembly blocks are placed into the annular fixing disk 406, the side push assembly 6 drives the rotating disk 404 at the bottom of the annular fixing disk 406 to rotate. The rotation of the rotating disk 404 causes multiple clamping assemblies 5 to move towards the rotation center on the annular fixing disk 406, and the multiple clamping assemblies 5 push the multiple iron core assembly blocks to retract inward to form a circle. By setting a protective cover 409 on the annular fixing disk 406, the contact between the stator bridge and the equipment is reduced, thereby reducing the risk of scratching the bridge line.

[0032] After the iron core assembly is clamped onto the positioning block 502, the spring 503 causes the pressure block 504 to press against the iron core assembly. When the side-push cylinder 602 pushes the rotating disk 404 to rotate, the sliding column 505 in the arc-shaped inclined groove 405 and the slide hole 4062 drives the slider 501 to slide on the slide 4061, thereby splicing multiple iron core assemblies into a circle. After the iron core assembly is clamped in place, the spring 503 presses against the pressure block 504, making the splicing and clamping method simple and eliminating the risk of the iron core assembly falling.

[0033] The dovetail groove structure is used for circumferential positioning of the iron core, while the straight groove structure only participates in guidance during operation, making clamping more convenient and faster.

[0034] After the iron core assembly block is clamped, the side-push cylinder 602 drives the rotating shaft 605 on the floating joint 603 to extend forward, and then drives the rotating disk 404 to rotate by the rotating shaft 605 sliding in the arc-shaped inclined groove 405. The combined structure of the rotating shaft 605 and the arc-shaped inclined groove 405 is similar to a force-saving lever, which can effectively reduce the required thrust of the side-push cylinder 602.

[0035] After the iron core assembly blocks are assembled, the pressing cylinder 807 drives the sliding plate 803 to move downward along the guide post 801. The sliding plate 803 drives the stator pressing head 805 on the pressing head fixing block 804 to move downward, so that multiple anti-rotation blocks 8051 correspond one-to-one with multiple iron core assembly blocks, thereby realizing the iron core assembly without rotation and pressing it into the squirrel cage 305. The four guide posts 801 plus the safety spring 802 can protect the equipment from the safety risk caused by its own weight falling when the pressing cylinder 807 is accidentally cut off.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
