Description

A stacked adjustable tire structure for stator cores Technical Field

[0001] This invention relates to the field of motor-related technologies, specifically to a stacked adjustable tire structure for stator cores. Background Technology

[0002] Motor stator cores are typically made of multiple sector-shaped laminations stacked together. They are mainly used in synchronous motors and large and medium-sized asynchronous motors. The sector-shaped laminations are usually positioned by a stacking fixture. Most stacking fixtures have a ring-shaped positioning rod or expansion structure in the center. The ring-shaped positioning rod forms a rigid support to ensure that the inner diameter of the laminations is aligned.

[0003] Currently, the existing stacking jig's inner diameter positioning structure is a welded structure, which is a fixed structure and therefore cannot be adjusted. This makes it inconvenient to disassemble the stacked laminations, greatly reducing the practicality of the adjustable jig. Moreover, the existing stacking jig's inner diameter positioning structure is not convenient for synchronous adjustment of the lamination thickness, resulting in low effectiveness of the stacking jig's inner diameter positioning structure in practical applications. Therefore, a stacking adjustable jig structure for stator cores is needed to realize the manufacturing of additive manufacturing devices. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a stacked adjustable stator core structure.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] Tire adjustment assembly, with a loading and unloading assembly on top;

[0008] The tire adjusting assembly includes a central positioning shaft. A tire lower pad is fixedly connected to the lower surface of the central positioning shaft. A fixing hole 1 is formed on the upper surface of the left end of the tire lower pad. A tire with a keyway is inserted into the inner cavity of the fixing hole 1.

A tire middle support plate is fixedly connected to the middle section of the central positioning shaft. Multiple support arc ribs are fixedly connected to the lower part of the tire middle support plate and to the surface of the central positioning shaft. Three tire adjusting inner columns are fixedly connected to the upper surface of the rear end of the tire middle support plate. A tire upper cover plate is sleeved on the upper surface of each of the three tire adjusting inner columns. A level bolt is threaded to the contact point between the tire upper cover plate and the tire with the keyway and each tire. A tire adjusting cylinder is fixedly installed on the upper surface of the front end of the tire middle support plate, and the upper end of the tire adjusting cylinder is fixedly installed on the lower surface of the front end of the tire upper cover plate.

[0009] As a preferred embodiment of the present invention, each of the tire outer surfaces is provided with a driven hexagonal groove.

[0010] As a preferred embodiment of the present invention, the lower surface of the lower pad of the tire is fixedly connected with a number of lower brackets equal to the number of outer tires of the tire, and each lower bracket is equipped with a bearing at its lower end.

[0011] As a preferred embodiment of the present invention, each of the lower brackets is rotatably connected to an internal hex wrench at its lower end via a bearing, and the upper end of each internal hex wrench is inserted into the interior of each driven hexagonal slot.

[0012] As a preferred embodiment of the present invention, a lower sprocket is fixedly sleeved on the lower end surface of each of the hex wrenches, and a lower chain is meshed in the groove of each lower sprocket. An adjustment motor is fixedly installed on the back of the lower end of the lower bracket directly in front, and the output shaft of the adjustment motor is fixedly connected to the lower end of the hex wrench directly in front.

[0013] As a preferred embodiment of the present invention, the loading and unloading assembly includes multiple upper brackets 1, the lower end of each upper bracket 1 being fixedly connected to the outer periphery of the upper surface of the tire cover plate, a shifting cylinder being fixedly installed on the upper surface of the left end of the tire cover plate, an upper bracket 2 being fixedly connected to the left end of the shifting cylinder, a limiting sleeve being rotatably connected to the upper end of each upper bracket 1 and upper bracket 2 via a bearing, and an internal hex wrench 2 being inserted into the inner cavity of the lower end of each limiting sleeve.

[0014] As a preferred embodiment of the present invention, a positioning arc plate is fixedly connected to the left side of the upper bracket two and to the upper surface of the tire cover plate.

[0015] As a preferred embodiment of the present invention, each of the limiting sleeves has a threaded hole on its upper end face, a pull rod is inserted into the inner cavity of each threaded hole, and the lower end of each pull rod is rotatably connected to the upper end face of the internal hex wrench via a bearing. A hand plate is fixedly connected to the upper end of each pull rod.

[0016] As a preferred embodiment of the present invention, each of the upper end of the limiting sleeve is fitted with a positioning spring, and the lower end of each positioning spring is fixedly connected to the upper end face of each hexagonal wrench II. The lower end of each pull rod is provided with an external thread.

[0017] As a preferred embodiment of the present invention, an upper sprocket is fixedly sleeved on the outer surface of the middle section of each limiting sleeve, and an upper chain is meshed in the groove of each upper sprocket. An upper driven gear is fixedly connected to the outer surface of the lower end of the limiting sleeve directly in front. A loading and unloading motor is fixedly installed on the upper surface of the front end of the fixture cover plate. A main drive gear is fixedly sleeved on the output shaft surface of the upper end of the loading and unloading motor. A magnetic ring is fixedly connected to the upper surface of each upper sprocket.

[0018] The beneficial effects of this invention are:

[0019] 1. This type of stator core uses a stacked adjustable jig structure. Through the fixed hole and the keyway outer jig, the fixed hole first facilitates the positioning of the keyway outer jig after installation. Then, the keyway outer jig is a fixed structure, which can facilitate the verticality of the generatrix of the stacked laminations, thereby improving the positioning effect of the adjustable jig structure on the stacked laminations.

[0020] 2. This type of stator core uses a stacked adjustable tire structure. Through the setting of an adjusting motor and an Allen wrench, firstly, controlling the adjusting motor to rotate forward drives the lower sprocket and lower chain to rotate forward simultaneously. The forward rotation of the lower sprocket drives multiple Allen wrenches to rotate forward, and the forward rotation of the Allen wrenches drives multiple tire outer casings to rotate forward simultaneously. When the arc surface on the tire outer casing fully contacts the surface of the inner diameter of the stacked laminations, the inner diameter positioning of multiple sector laminations is quickly completed. Manual positioning saves time and effort. Then, controlling the adjusting motor to rotate in reverse drives multiple tire outer casings to rotate in reverse. When the flat part on the tire outer casing corresponds to the inner diameter surface of the stacked laminations, the inner diameter change of the adjustable tire structure is quickly completed, thus facilitating workers to quickly complete tire removal work and greatly improving the practicality of the adjustable tire structure.

[0021] 3. This type of stator core uses a stacked adjustable tire structure. Through the setting of support arc ribs and outer tire intermediate support plate, the support arc ribs can firstly provide convenient support for the outer tire intermediate support plate, thereby improving the service life of the outer tire intermediate support plate. Then, the outer tire intermediate support plate can conveniently support multiple tires, thus effectively preventing tire deformation.

[0022] 4. This type of stator core uses a stacked adjustable tire structure. Through the setting of the adjustable tire cylinder and the adjustable tire inner column, the adjustable tire inner column can first limit the movement direction of the upper cover plate of the fixture and improve the stability of the upper cover plate during movement. Then, by controlling the start of the adjustable tire cylinder, the upper cover plate of the fixture can be moved upward. The upward movement of the upper cover plate of the fixture can first facilitate the disassembly of multiple outer tires of the fixture, and then facilitate the installation of outer tires of fixtures of different heights. This enables the adjustable tire structure to support and position the inner diameter of stacked laminations of different thicknesses, improves the performance of the adjustable tire structure in practical applications, realizes the manufacturing of additive manufacturing equipment, and further improves the production efficiency of stacked products.

[0023] 5. This type of stator core uses a stacked adjustable tire structure. Through a loading / unloading motor and a shifting cylinder, firstly, controlling the loading / unloading motor to rotate forward drives the main drive gear to rotate forward. The main drive gear's forward rotation drives the upper driven gear to rotate in reverse. The upper driven gear's reverse rotation drives the upper sprocket and upper chain to rotate in reverse simultaneously. The upper sprocket's reverse rotation drives multiple limit sleeves and Allen wrenches to rotate in reverse simultaneously. The Allen wrenches' reverse rotation drives multiple equal-height bolts to rotate in reverse. When the lower ends of the multiple equal-height bolts disengage from the threaded grooves of each tire's outer casing, the upper casing cover plate and the tire can be quickly unlocked, facilitating the rapid disassembly and replacement of multiple tires. Then, controlling the loading / unloading motor to rotate in reverse drives multiple Allen wrenches to rotate forward simultaneously. Reversing the angle wrench two will cause the leveling bolt to rotate forward. The forward rotation of the leveling bolt will cause it to move downward again into the screw groove at the top of each tire. At this time, the locking between the tire cover plate and the tire is quickly completed, which effectively improves the reuse rate of the adjustable tire. Finally, starting the control cylinder will drive the upper support two to move to the right. The upper support two moving to the right will drive the limit sleeve and the internal hex wrench two to move to the right at the same time. The internal hex wrench two moving to the right will drive the leveling bolt away from the keyway on the tire cover plate. At this time, the stacked stamping embedded in the tire with the keyway can be easily disengaged from the adjustable tire structure. This makes it time-saving and labor-saving to pick up the stacked products, greatly improving the user experience of the adjustable tire structure.

[0024] 6. This type of stator core uses a stacked adjustable tire structure. Through a hand lever, pull rod, threaded hole, external thread, and magnetic ring, the hand lever is first pulled upwards, causing the external thread to contact the inner wall of the threaded hole. Then, rotating the hand lever forward drives the pull rod forward, which in turn engages the external thread with the inner wall of the threaded hole, quickly positioning the pull rod. The magnetic ring then transmits magnetism to the internal hex wrench two via a suitable spring. As the pull rod moves upwards, it attracts and moves the leveling bolt upwards, facilitating automatic disengagement of the leveling bolt from the tire cover plate. This improves the efficiency of leveling bolt replacement and effectively extends the service life of the loading and unloading components. Finally, the magnetic ring also attracts the upper chain when the internal hex wrench two is moved by the shifting cylinder, effectively preventing the upper chain from disengaging from the upper sprocket. This significantly reduces manual operation steps, further improving the automation level of the adjustable tire structure and enhancing the user experience of loading and unloading components.

[0025] 7. This type of stator core uses a stacked adjustable tire structure. Through the setting of the positioning arc plate, the positioning arc plate can quickly position the upper support two at the work position during tire unloading, thereby effectively improving the efficiency of loading and unloading components for reuse.

[0026] 8. This type of stator core uses a stacked adjustable jig structure. Through the set central positioning shaft, the entire adjustable jig structure can be easily installed in the center position of the stacking jig, thereby ensuring the stability of the adjustable jig structure during use.

[0050] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0051] Example: As shown in Figures 1-21, the present invention provides a stacking adjustable jig structure for stator cores, comprising: a jig adjustment assembly 1, with a loading / unloading assembly 2 on the top of the jig adjustment assembly 1; the jig adjustment assembly 1 includes a central positioning shaft 101, which is used to be installed at the center of the stacking jig, thereby facilitating the positioning of the stacked laminations by the entire jig adjustment assembly 1; a jig lower pad 102 is fixedly connected to the lower end surface of the central positioning shaft 101; a first fixing hole 103 is provided on the upper surface of the left end of the jig lower pad 102; an outer jig 104 with a keyway is inserted into the inner cavity of the first fixing hole 103; multiple second fixing holes 105 are provided outside the position of the first fixing hole 103 and located on the outer periphery of the upper surface of the jig lower pad 102; and each second fixing hole 105 is inserted into the inner cavity of the second fixing hole 105. There is a tire 106. A middle support plate 107 is fixedly connected to the surface of the middle section of the central positioning shaft 101. Multiple support ribs 108 are fixedly connected to the lower part of the middle support plate 107 and the surface of the central positioning shaft 101. Three tire adjusting inner posts 109 are fixedly connected to the upper surface of the rear end of the middle support plate 107. A tire cover plate 110 is sleeved on the upper surface of each of the three tire adjusting inner posts 109. A height equalizing bolt 111 is threadedly connected to the contact position between the tire cover plate 110 and the tire 104 with keyway and each tire 106. A tire adjusting cylinder 112 is fixedly installed on the upper surface of the front end of the middle support plate 107. The upper end of the tire adjusting cylinder 112 is fixedly installed on the lower surface of the front end of the tire cover plate 110.

[0052] As shown in Figures 16 and 17, the outer tire 106 and the upper cover plate 110 of the tire are designed such that the diameter of the outer tire 106 extending from the arc surface is larger than the diameter of the upper cover plate 110. After the outer tire 106 is rotated, the diameter of the outer tire 106 is the same as the diameter of the upper cover plate 110. This allows for easy tire removal when the outer tire 106 extends from the plane. This structural design is not obstructed by the loading and unloading components 2, thus ensuring the smoothness of tire removal.

[0053] Among them, the supporting arc rib 108 and the tire intermediate support plate 107 are provided. First, the supporting arc rib 108 can easily support the tire intermediate support plate 107, which improves the service life of the tire intermediate support plate 107. Then, the tire intermediate support plate 107 can easily support multiple tires 106, so as to effectively prevent tire deformation.

[0054] The adjustable tire cylinder 112 and the adjustable inner column 109 allow the inner column 109 to limit the movement direction of the upper cover plate 110 and improve its stability during movement. The adjustable cylinder 112 then moves the upper cover plate 110 upwards. This upward movement facilitates the removal of multiple outer tires 106 and allows for the installation of outer tires 106 of different heights. This enables the adjustable tire structure to support and position the inner diameter of stacked laminations of varying thicknesses, further enhancing its practicality.

[0055] Each tire 106 has a driven hexagonal groove 113 on its lower end face; the same number of lower brackets 114 as the tire 106 are fixedly connected to the outer periphery of the lower surface of the tire lower pad 102, and each lower bracket 114 has a bearing installed at its lower end; each lower bracket 114 has an internal hexagonal wrench 115 rotatably connected to its lower end via the bearing, and the upper end of each internal hexagonal wrench 115 is inserted into the interior of each driven hexagonal groove 113; each internal hexagonal wrench 115 has a lower sprocket 116 fixedly fitted onto its lower surface, and each lower sprocket 116 has a lower chain 117 meshing in its groove; a positioning motor 118 is fixedly installed on the back of the lower end of the lower bracket 114 at the front, and the output shaft of the positioning motor 118 is fixedly connected to the lower end of the internal hexagonal wrench 115 at the front.

[0056] The system utilizes a positioning motor 118 and hex wrenches 115. First, controlling the positioning motor 118 to rotate forward drives the lower sprocket 116 and lower chain 117 to rotate simultaneously. The rotation of the lower sprocket 116 then drives multiple hex wrenches 115 to rotate forward, which in turn drives multiple tires 106 to rotate simultaneously. When the arc surface of the tire 106 fully contacts the surface of the inner diameter of the stacked stampings, the inner diameter positioning of multiple sector stampings is quickly completed. This manual positioning saves time and effort. Then, controlling the loading / unloading motor 215 to rotate forward drives the main drive gear 216 to rotate forward. The rotation of the main drive gear 216 then drives the upper driven gear 214 to rotate in reverse. The reverse rotation of the upper driven gear 214 then drives the upper sprocket 212 and... The upper chain 213 reverses simultaneously, and the upper sprocket 212 reverses, which in turn drives multiple limit sleeves 204 and hex wrench 205 to reverse simultaneously. The reverse rotation of hex wrench 205 drives multiple equal-height bolts 111 to reverse. When the lower ends of multiple equal-height bolts 111 disengage from the threaded grooves of each tire outer tire 106, the unlocking between the tire upper cover plate 110 and the tire outer tire 106 can be quickly completed. Then, controlling the adjustment motor 118 to reverse will drive multiple tire outer tires 106 to reverse. When the flat part on the tire outer tire 106 corresponds to the inner diameter of the stacked stamping, the inner diameter change of the adjustable tire structure is quickly completed, which facilitates the workers to complete the initial tire removal work, thus greatly improving the practicality of the adjustable tire structure.

[0057] The loading and unloading assembly 2 includes multiple upper support brackets 201. The lower end of each upper support bracket 201 is fixedly connected to the outer periphery of the upper surface of the fixture cover plate 110. A shifting cylinder 202 is fixedly installed on the upper surface of the left end of the fixture cover plate 110. An upper support bracket 203 is fixedly connected to the left end of the shifting cylinder 202. Each upper support bracket 201 and the upper end of the upper support bracket 203 are rotatably connected to a limiting sleeve 204 via a bearing. An internal hex wrench 205 is inserted into the inner cavity of the lower end of each limiting sleeve 204. A positioning arc plate 206 is fixedly connected to the left side of the upper support bracket 203 and located on the upper surface of the fixture cover plate 110. Each limiting sleeve 204 has a threaded hole 207 on its upper end face. A pull rod 208 is inserted into the inner cavity of each threaded hole 207, and the lower end of each pull rod 208 is connected to the internal hex wrench 205 via a bearing. 5. The upper end face is rotatably connected, and a hand plate 209 is fixedly connected to the upper end of each pull rod 208; a positioning spring 210 is respectively fitted into the inner cavity of the upper end of each limiting sleeve 204, and the lower end of each positioning spring 210 is fixedly connected to the upper end face of each internal hex wrench 205. The lower end surface of each pull rod 208 is provided with external thread 211; an upper sprocket 212 is fixedly fitted onto the outer surface of the middle section of each limiting sleeve 204, and an upper chain 213 is meshed in the groove of each upper sprocket 212. An upper driven gear 214 is fixedly connected to the outer surface of the lower end of the limiting sleeve 204 directly in front. A loading and unloading motor 215 is fixedly installed on the upper surface of the front end of the fixture cover plate 110. A main drive gear 216 is fixedly fitted onto the output shaft surface of the upper end of the loading and unloading motor 215. A magnetic ring 217 is fixedly connected to the upper surface of each upper sprocket 212.

[0058] The system comprises a handplate 209, a pull rod 208, a threaded hole 207, an external thread 211, and a magnetic ring 217. First, pulling the handplate 209 upwards causes the external thread 211 to contact the inner wall of the threaded hole 207. Then, rotating the handplate 209 forward causes the pull rod 208 to rotate forward, which in turn engages the external thread 211 with the inner wall of the threaded hole 207, quickly positioning the pull rod 208. Next, the magnetic ring 217 transmits magnetism to the hex wrench 205 via the appropriate spring 210. As the pull rod 208 moves upwards, it attracts the leveling bolt 111, allowing it to move upwards and facilitating automatic disengagement of the leveling bolt 111 from the fixture cover plate 110, thus improving the user's efficiency in replacing the leveling bolt 111.

[0059] Among them, the positioning arc plate 206 can quickly position the upper support 203 at the work position during tire unloading, thereby effectively improving the efficiency of reusing the loading and unloading component 2.

[0060] During operation, firstly, controlling the positioning motor 118 to rotate forward will drive the lower sprocket 116 and lower chain 117 to rotate forward simultaneously. The forward rotation of the lower sprocket 116 will drive multiple Allen wrenches 115 to rotate forward, and the forward rotation of the Allen wrenches 115 will drive multiple jig outer tires 106 to rotate forward simultaneously. When the arc surface on the jig outer tire 106 is in full contact with the surface of the inner diameter of the stacked stampings, the inner diameter positioning of multiple sector stampings is quickly completed. Manual positioning saves time and effort. At this point, controlling the loading / unloading motor 215 to rotate forward will drive the main drive gear 216 to rotate forward. The main drive gear 216 rotating forward will drive the upper driven gear 214 to rotate in reverse. The upper driven gear 214 rotating in reverse will drive the upper sprocket 212 and the upper chain 213 to rotate in reverse simultaneously. The upper sprocket 212 rotating in reverse will drive multiple limit sleeves 204 and hex wrench 205 to rotate in reverse simultaneously. The hex wrench 205 rotating in reverse will drive multiple equal-height bolts 111 to rotate in reverse. When multiple When the lower end of the equalizing bolt 111 disengages from the threaded groove of each tire outer 106, the unlocking between the tire upper cover plate 110 and the tire outer 106 can be quickly completed. Then, controlling the reversing motor 118 can drive multiple tire outer 106 to reverse. When the flat part on the tire outer 106 corresponds to the inner diameter of the stacked punch, the inner diameter change of the adjustable tire structure is quickly completed, which facilitates the workers to complete the initial tire removal work. Finally, controlling the starting of the shifting cylinder 202 can drive the upper support 203 to move to the right. The upper support 203 moving to the right can drive the limit sleeve 204 and the internal hex wrench 205 to move to the right at the same time. The internal hex wrench 205 moving to the right can drive the equalizing bolt 111 away from the keyway on the tire upper cover plate 110. At this time, the stacked punch embedded in the tire with the keyway can easily detach upward from the entire adjustable tire structure, so as to fully complete the tire removal work.

[0061] Replacement of the equal-height bolt 111: First, pull the lever 209 upwards to make the external thread 211 contact the inner wall of the threaded hole 207. Then, rotating the lever 209 forward will drive the pull rod 208 to rotate forward. The rotation of the pull rod 208 will make the external thread 211 engage with the inner wall of the threaded hole 207, thus quickly completing the positioning of the pull rod 208. Then, the magnetic ring 217 can transmit the magnetism to the internal hex wrench 205 through the appropriate spring 210. When the pull rod 208 moves upwards, it can attract the equal-height bolt 111 to move upwards, thereby facilitating the automatic disengagement of the equal-height bolt 111 from the upper cover plate 110 of the fixture, thus improving the user's efficiency in replacing the equal-height bolt 111.

[0062] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
