Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, specifically to a stator shaping device for micro motors. Background Technology

[0002] The stator of a micro motor is the core component for electromagnetic energy conversion. The stator is mainly composed of an iron core and winding coils wound in the iron core slots. Its structural regularity directly affects the assembly accuracy, operational stability and energy efficiency of the motor. During the stator production process, after the coils are wound by automatic or semi-automatic equipment, problems such as loosening, dimensional deviation and messy coil arrangement are likely to occur at the winding ends, which cannot meet the accuracy requirements of subsequent housing pressing and rotor assembly. Therefore, it is necessary to shape the stator windings. Traditional manual shaping requires operators to hold simple tools such as pliers and arc-shaped pressure plates to apply pressure to the top, bottom and outer coils of the stator point by point, manually adjusting the coil arrangement and overall outline to make it fit the shape of the iron core and meet the dimensional standards.

[0003] However, the existing technology has the following problems: Manual shaping relies on the operator's experience and feel. Different operators have different pressure and operating techniques, which leads to inconsistent appearance quality of the stator after shaping. In addition, the process of manually adjusting each piece is cumbersome and takes a long time to shape a single stator, making it difficult to meet the needs of large-scale production. Summary of the Invention

[0004] The purpose of this invention is to provide a micro-motor stator shaping device to solve the above-mentioned problems, and to overcome the shortcomings of the existing manual shaping technology, such as the unstable appearance quality and poor work efficiency, as detailed below.

[0006] Preferably, the material platform assembly further includes a slide plate, the top of the operating table is provided with a slot, the slide plate is horizontally slidably connected in the slot, and the base is connected to the slide plate.

[0007] Preferably, the base is connected to a convex shaft, and the stator can be fitted outside the convex shaft for positioning. The bottom of the pressure block is provided with a round hole that matches the size of the convex shaft, and the convex shaft can be inserted into the round hole of the pressure block when the pressure block moves down.

[0008] Preferably, the ring pressing mechanism includes multiple slide seats, all of which are slidably connected to the bottom of the pressing block. Multiple clamping blocks are respectively installed on the multiple slide seats. A sliding shaft is connected to the top of each slide seat. A grooved plate is rotatably connected inside the pressing block. Multiple arc-shaped grooves are formed in a circumferential array on the grooved plate. The multiple sliding shafts are slidably connected to the arc-shaped grooves of the grooved plate. When the grooved plate rotates, it can drive the multiple sliding shafts to move synchronously to the center through the multiple arc-shaped grooves.

[0009] Preferably, a positioning disc is vertically slidably connected inside the pressure block, and a grooved shaft is connected to the bottom of the positioning disc. The bottom of the grooved shaft is located inside the circular hole of the pressure block, and a spiral groove is formed on the grooved shaft. The inner wall of the grooved disc is movably connected to the outer wall of the grooved shaft, and a sliding tongue is connected to the inner wall of the grooved disc. The sliding tongue is slidably connected to the spiral groove of the grooved shaft. When the grooved shaft moves vertically, the grooved disc can be rotated by the cooperation of the spiral groove and the sliding tongue.

[0010] Preferably, the clamping block is horizontally slidably connected to the slide block, and an adjusting screw is rotatably connected to the clamping block, with the adjusting screw being threadedly connected to the slide block.

[0011] Preferably, the material platform assembly further includes a lifting mechanism, which includes two top blocks, both of which are vertically slidably connected to the base. A light rod is connected between the bottoms of the two top blocks, and an inclined block is installed in the slot of the operating table, the inclined block being located on the movement trajectory of the light rod.

[0012] Preferably, the light rod has a gap with the bottom surface of the slide plate, and the light rod moves upward due to the counter-pushing force of the inclined block when it comes into contact with the inclined block.

[0013] Preferably, the operating table is provided with a protective component, which includes two side frames. Two limit rods are respectively connected between the two side frames and the operating table. The outer wall of the pressure block is provided with four limit holes, and the four limit rods are slidably connected to the four limit holes respectively.

[0014] Preferably, each of the two side frames is connected to a grating, which is connected to the control system of the hydraulic cylinder. When a human body or object is detected between the two gratings, the operation of the hydraulic cylinder can be paused.

[0015] The beneficial effects are: 1. This micro motor stator shaping device, through the cooperation of the pressing component and the material table component, enables the convex shaft to be embedded in the round hole of the pressing block when the pressing block is pressed down, forming an axial guide positioning, so that the pressing block and the base are precisely aligned, ensuring that the upper and lower ends of the stator are evenly pressed, the upper end of the stator contacts the bottom of the pressing block, and the lower end contacts the base. When the pressing block applies pressure to the stator, it achieves the leveling of the upper and lower ends of the stator.

[0016] 2. This micro-motor stator shaping device, through the setting of the ring pressing mechanism, enables multiple clamping blocks to move synchronously towards the center, thereby achieving uniform ring pressing on the outer coil of the stator and playing a shaping role on the outer coil of the stator. This allows the upper and lower ends of the stator and the outer coil to be simultaneously subjected to the surrounding pressure of the pressure block, the base and multiple clamping blocks, thus achieving a better shaping effect and high work efficiency.

[0017] 3. The stator shaping device for micro motors, through the setting of the lifting mechanism, enables the smooth rod to drive the two top blocks to move upward and protrude from the top surface of the base after the shaping operation is completed, thereby lifting the stator on the base, making it easier for the staff to remove the stator from the cam shaft, and avoiding the stator being pressed tightly on the cam shaft during the shaping process and making it difficult to remove.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0022] The first embodiment of the present invention is as follows: Please see Figure 1 - Figure 8 A micro motor stator shaping device includes an operating table 1, on which a pressing component 2 is provided. The pressing component 2 includes a mounting frame 21, which is mounted on the operating table 1. A hydraulic cylinder 22 is mounted on the mounting frame 21, and the output end of the hydraulic cylinder 22 is connected to a pressing block 23. When the hydraulic cylinder 22 is started, it drives the pressing block 23 to move down or up. When there is a stator below the pressing block 23, the pressing block 23 moves down to apply pressure to the stator, thereby completing the shaping of the top of the stator.

[0023] Furthermore, the operating table 1 is equipped with a material platform assembly 3, which includes a base 32. When the pressure block 23 is pressed down, it cooperates with the base 32 to apply pressure and level the upper and lower ends of the stator. The material platform assembly 3 also includes a sliding plate 31. The top of the operating table 1 is provided with a slot, and the sliding plate 31 is horizontally slidably connected to the slot. The base 32 is connected to the sliding plate 31, and a convex shaft 33 is connected to the base 32. The stator can be fitted onto the outside of the convex shaft 33 for positioning. The bottom of the pressure block 23 is provided with a round hole that matches the size of the convex shaft 33. When the pressure block 23 moves down, the convex shaft 33 can be inserted into the round hole of the pressure block 23. The sliding plate 31 can slide back and forth along the slot, and the sliding plate 31 is provided with a handle, which the operator can use to pull... The sliding plate 31, similar to a drawer, moves the upper base 32 and the cam shaft 33 synchronously when it slides back and forth. The outer diameter of the cam shaft 33 matches the inner hole of the stator. During operation, the sliding plate 31 is first pulled forward using the handle, and then the stator is fitted into the cam shaft 33 to achieve radial positioning. Then, the sliding plate 31 is pushed backward, causing the base 32 to move forward to directly below the pressure block 23. When the pressure block 23 is pressed down, the cam shaft 33 is embedded in the round hole of the pressure block 23 to form axial guiding positioning, so that the pressure block 23 and the base 32 are precisely aligned, ensuring that the upper and lower ends of the stator are evenly pressed. The upper end of the stator contacts the bottom of the pressure block 23, and the lower end contacts the base 32. When the pressure block 23 applies pressure to the stator, it achieves leveling of the upper and lower ends of the stator.

[0024] In addition, the pressing assembly 2 also includes a ring pressing mechanism 4, which includes multiple clamping blocks 42. These clamping blocks 42 can move from the outer ring of the stator towards the stator when the pressing block 23 is pressed down, thereby applying pressure to the outer wall coil of the stator for shaping. The ring pressing mechanism 4 includes multiple sliding blocks 41, all of which are slidably connected to the bottom of the pressing block 23. Multiple clamping blocks 42 are respectively mounted on the multiple sliding blocks 41. A sliding shaft 43 is connected to the top of each sliding block 41. A slotted plate 44 is rotatably connected inside the pressing block 23. Multiple arc-shaped grooves are formed in a circumferential array on the slotted plate 44. Multiple sliding shafts 43 are slidably connected to the arc-shaped grooves of the slotted plate 44. When the slotted plate 44 rotates, it can drive the multiple sliding shafts 43 to move synchronously in the center through the multiple arc-shaped grooves. Multiple long... The slide block 41 is slidably connected to the long slot. The slide block 41 can only slide within the long slot. Multiple long slots are radially distributed at the bottom of the pressure block 23. The clamping block 42 moves synchronously with the slide block 41. The top of the slide shaft 43 is embedded in the arc-shaped slot of the slot plate 44 to form a sliding fit. When the slot plate 44 rotates, the side wall of the arc-shaped slot generates a radial thrust on the slide shaft 43. The multiple arc-shaped slots drive multiple slide shafts 43 and corresponding slide blocks 41 and clamping blocks 42 to move synchronously towards the center, thereby achieving uniform ring pressure on the outer coil of the stator and playing a shaping role on the outer coil of the stator. This allows the upper and lower ends of the stator and the outer coil to be simultaneously subjected to the ring pressure of the pressure block 23, the base 32 and multiple clamping blocks 42, thus achieving a better shaping effect and higher work efficiency.

[0025] In addition, a positioning disc 46 is vertically slidably connected inside the pressure block 23. A spring is provided between the positioning disc 46 and the inner wall of the top of the pressure block 23. A grooved shaft 45 is connected to the bottom of the positioning disc 46. The bottom of the grooved shaft 45 is located in the circular hole of the pressure block 23. A spiral groove is provided on the grooved shaft 45. The inner wall of the grooved disc 44 is movably connected to the outer wall of the grooved shaft 45. A sliding tongue 441 is connected to the inner wall of the grooved disc 44. The sliding tongue 441 is slidably connected to the spiral groove of the grooved shaft 45. When the grooved shaft 45 moves vertically, it can drive the grooved disc 44 to rotate by the cooperation of the spiral groove and the sliding tongue 441. A limiting mechanism is provided inside the positioning disc 46 and the pressure block 23. The positioning disc 46 and the grooved shaft 45 connected to it can only slide up and down and cannot rotate. The spiral groove on the outer wall of the grooved shaft 45 and the sliding tongue 441 on the inner wall of the grooved disc 44 form a spiral transmission relationship. When the pressure block 23 presses down... During the process, when the convex shaft 33 is inserted into the round hole of the pressure block 23, the convex shaft 33 abuts against the groove shaft 45 and pushes the groove shaft 45 upward. The positioning plate 46 moves upward and compresses the spring. When the groove shaft 45 moves upward, the side wall of its spiral groove pushes the sliding tongue 441 to produce circumferential displacement, thereby driving the groove plate 44 to rotate around the axis, thus achieving the effect of synchronous centering of multiple clamping blocks 42. When the pressure block 23 moves upward and resets, after the convex shaft 33 disengages from the groove shaft 45, the positioning plate 46 moves downward and resets using the spring force. The groove shaft 45 moves downward and resets accordingly. At the same time, the groove plate 44 rotates and resets using the cooperation of the spiral groove and the sliding tongue 441. When the groove plate 44 rotates and resets, the cooperation of multiple arc grooves and the sliding shaft 43 drives multiple sliding blocks 41 and clamping blocks 42 to move outward and reset synchronously, so that the clamping blocks 42 disengage from the outer wall of the stator. At this time, the stator shaping operation is completed.

[0026] It is worth noting that the clamping block 42 is horizontally slidably connected to the slide block 41, and an adjusting screw 421 is rotatably connected to the clamping block 42. The adjusting screw 421 is threadedly connected to the slide block 41. The clamping block 42 is slidably connected to the slide block 41 through multiple pins. The pins on the clamping block 42 can slide on the slide block 41, thereby adjusting the distance between the clamping block 42 and the slide block 41. The larger the distance between the clamping block 42 and the slide block 41, the shorter the distance between the clamping block 42 and the central axis of the pressure block 23, so that the clamping block 42 can be adapted to stators with smaller outer diameters. When the adjusting screw 421 is rotated, the principle of thread transmission can be used to drive the clamping block 42 away from or closer to the slide block 41, thereby accurately adjusting the initial position of the clamping block 42. This allows the operator to fine-tune the pressure position of the clamping block 42 according to the coil thickness and shaping requirements of stators of different specifications, further improving the accuracy of ring pressing and shaping. At the same time, it is convenient to deal with the change of stator model during the production process, improving the adaptability and operational flexibility of the device.

[0027] Based on the above embodiments, the second embodiment of the present invention is as follows: Please see Figure 1 , Figure 9The material platform assembly 3 also includes a lifting mechanism 5, which includes two top blocks 51. Both top blocks 51 are vertically and slidably connected to the base 32. A guide rod 52 is connected between the bottoms of the two top blocks 51. An inclined block 53 is installed in the slot of the operating table 1. The inclined block 53 is located on the movement trajectory of the guide rod 52. There is a gap between the guide rod 52 and the bottom surface of the slide plate 31. When the guide rod 52 contacts the inclined block 53, it is pushed upward by the counterforce of the inclined block 53. When the guide rod 52 does not contact the inclined block 53, the two top blocks 51 do not protrude from the top surface of the base 32 and are located below the stator. After the shaping is completed, the slide plate 31 is pulled forward, and the slide plate 31 drives the base. When base 32 moves forward, it drives the two top blocks 51 to move forward synchronously. During the forward movement of the two top blocks 51, the light rods 52 at the bottom of the two top blocks 51 come into contact with the inclined block 53, so that the light rods 52 slide upward along the inclined surface of the inclined block 53. The light rods 52 drive the two top blocks 51 to move upward and protrude from the top surface of base 32, thereby lifting the stator on base 32, making it easier for the staff to remove the stator from the cam shaft 33, and avoiding the stator being pressed on the cam shaft 33 during the shaping process and making it difficult to remove. After placing the next stator, push the slide plate 31 backward, and the light rods 52 gradually detach from the inclined block 53. The two top blocks 51 and the light rods 52 fall down by gravity, and the top blocks 51 retract into the top surface of base 32.

[0028] Based on the above embodiments, the third embodiment of the present invention is as follows: Please see Figure 1 , Figure 2 The operating table 1 is equipped with a protective component 6, which includes two side frames 61. Two limit rods 62 are connected between the two side frames 61 and the operating table 1, respectively. The outer wall of the pressure block 23 is provided with four limit holes, and the four limit rods 62 are slidably connected to the four limit holes. The four limit rods 62 are rectangularly distributed and form a sliding fit with the four limit holes on the outer wall of the pressure block 23, which plays a precise guiding and limiting role in the lifting and lowering movement of the pressure block 23, preventing the pressure block 23 from tilting or deviating during the lifting and lowering process, thereby ensuring the accuracy of stator shaping.

[0029] It is worth noting that each of the two side frames 61 is connected to a light grating 63. The light grating 63 is connected to the control system of the hydraulic cylinder 22. When a human body or object is detected between the two light gratings 63, the operation of the hydraulic cylinder 22 can be paused. The light grating 63 adopts an infrared through-beam structure. The two light gratings 63 are installed on the two side frames 61 respectively, forming an infrared protective light curtain that covers the front area of ​​the operating platform 1. The signal output terminal of the light grating 63 is electrically connected to the control system of the hydraulic cylinder 22. When the operator's limb or other object accidentally enters the protective area between the two light gratings 63, the light grating 63 will immediately detect the obstruction signal and transmit the signal to the control system. The control system will quickly issue a command to pause the operation of the hydraulic cylinder 22, so that the pressure block 23 stops lifting and lowering, effectively avoiding personnel injury or equipment collision accidents during the shaping process and improving the safety performance of the device.

[0030] In use, the operator first uses the handle on the slide plate 31 to pull the slide plate 31 forward along the slot at the top of the operating table 1, placing the stator to be shaped onto the outside of the convex shaft 33 on the base 32 for radial positioning. Then, the operator pushes the slide plate 31 backward, moving the base 32 and the stator directly below the pressure block 23. The hydraulic cylinder 22 is then activated, and its output end moves the pressure block 23 downward. At this time, the limiting rods 62 connected to the two side frames 61 of the protective component 6 on the operating table 1 slide and engage with the limiting holes on the outer wall of the pressure block 23, guiding and limiting the pressure block 23. Simultaneously, the gratings 63 on the two side frames 61... An infrared protective light curtain ensures operational safety. During the downward movement of the pressure block 23, the convex shaft 33 is embedded in the round hole at the bottom of the pressure block 23 to achieve axial guidance and positioning. The convex shaft 33 abuts against the bottom of the groove shaft 45 inside the pressure block 23 and pushes it upward. The positioning disk 46 connected to the groove shaft 45 moves upward synchronously and compresses the spring between it and the inner wall of the top of the pressure block 23. The spiral groove on the outer wall of the groove shaft 45 cooperates with the sliding tongue 441 on the inner wall of the groove disk 44 to drive the groove disk 44 to rotate inside the pressure block 23. The arc-shaped grooves in the circumferential array on the groove disk 44 drive multiple sliding shafts 43 to move synchronously in the center, thereby driving the sliding connection on the pressure block. Multiple slide blocks 41 at the bottom of the 23 and clamping blocks 42 mounted on the slide blocks 41 move closer to the outer ring of the stator. The operator can pre-adjust the initial position of the clamping blocks 42 to match the stator specifications by rotating the adjusting screw 421 threaded to the slide block 41 on the clamping blocks 42. At this time, the pressure block 23 and the base 32 cooperate to apply pressure to the upper and lower ends of the stator to flatten it. Multiple clamping blocks 42 apply pressure to the outer wall of the stator coil to shape it. After the shaping is completed, the hydraulic cylinder 22 drives the pressure block 23 to move up and reset. The positioning plate 46 moves down under the action of the spring force to drive the slotted shaft 45 to reset. The slotted plate 44 is driven by the spiral groove and the sliding tongue 441. The reverse rotation causes the sliding shaft 43, sliding base 41, and clamping block 42 to move outward and reset synchronously. The sliding plate 31 is pulled forward, causing the base 32 to move forward. The light rods 52 at the bottom of the two vertically sliding top blocks 51 on the base 32 contact the inclined block 53 in the slot of the operating table 1. The light rods 52 move upward under the counter-push force of the inclined block 53 and cause the two top blocks 51 to protrude from the top surface of the base 32, lifting the stator from the cam shaft 33. After the operator removes the stator, the sliding plate 31 is pushed backward, and the light rods 52 disengage from the inclined block 53. The top blocks 51 and the light rods 52 fall back to reset under the action of gravity, completing one shaping operation.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
