Description

Technical Field

[0001] This invention belongs to the technical field of automotive generator manufacturing equipment, and particularly relates to an automotive generator claw pole shaping device. Background Technology

[0002] Claw pole generators are commonly used in automobiles. Claw pole generators can increase the power generation of automobiles. During the manufacturing process of automobile generator claw poles, forward forming and lateral forming are used to improve the quality of the claw poles. Lateral forming can reduce the adverse effects of friction on the forming process during forward extrusion forming.

[0003] Existing lateral forming devices typically use lateral pressure plates to compress the claws when shaping the claw poles, thus preventing the free ends of the claws from deviating away from the claw pole's axis. However, in actual production, the claws may not only deviate away from the claw pole's axis, but adjacent claws may also deviate towards or away from each other. This results in existing lateral forming devices being unable to effectively perform the lateral forming operation on the claw poles, affecting the production quality of the claw poles.

[0004] Therefore, it is necessary to invent a claw pole shaping device for automobile generators to solve the above problems. Summary of the Invention

[0009] Furthermore, the pushing device includes a mounting ring, a pressure block, and a second electric push rod; The mounting ring is horizontally positioned at the top of the enclosure, and the mounting ring is coaxial with the conical support platform. The number of pressure blocks corresponds one-to-one with the number of push blocks. Multiple pressure blocks are evenly and fixedly connected to the bottom of the mounting ring, and the bottom of multiple pressure blocks can maintain contact with the top of multiple push blocks in the vertical direction. There are two second electric push rods, which are symmetrically and vertically fixedly connected to the top of the mounting ring, and the top of the second electric push rods is fixedly connected to the inner side wall of the U-shaped frame.

[0010] Furthermore, the clamping device includes an arc-shaped panel, a limiting block, a connecting rod, and a connecting sleeve; The arc panel slides against the side of the conical support platform, and the width of the arc panel gradually increases from top to bottom. The limiting block is fixedly connected to the side of the arc panel near the conical support platform, and the side of the conical support platform is provided with a limiting groove matching the limiting block along the inclined direction of its conical surface. The limiting block is slidably installed in the limiting groove. A connecting hole is provided through the limiting groove and the cavity of the conical support platform.

[0012] Furthermore, a lifting rod is slidably inserted through the top center of the claw pole, and the diameter of the lifting rod is smaller than the inner diameter of the pressure ring.

[0015] The technical effects and advantages of this invention are as follows: 1. The present invention has a clamping device. When the claw of the claw pole deviates, the squeezing action of the two arc plates along the conical surface of the conical support platform can make the claw of the claw pole more regular. In the end, the distance between two adjacent claws of the claw pole can be kept the same. In addition, with the squeezing action of the extrusion plate on the claw, the entire claw pole can be better shaped, thus improving the finished product quality of the claw pole. 2. This invention incorporates an adjustment component. When the extrusion plates experience varying degrees of wear due to uneven stress over a long period, the adjustment ring can be rotated after the claw pole shaping operation is completed. This allows the extrusion plates that are not in close contact with the claw pole to come into contact with the claw pole through the combined action of the adjustment ring, safety clutch gear, and adjustment rod. This adjusts the position of the more severely worn extrusion plates, ensuring that all extrusion plates can exert sufficient extrusion force on the claw pole under the action of the corresponding push block during subsequent shaping operations, thereby improving the shaping effect of the claw pole.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0019] This invention provides, for example Figures 1 to 7The illustrated automotive generator claw pole shaping device includes a base 1, a mounting plate 2 connected to the top of the base 1, a conical support platform 3 mounted at the center of the top of the mounting plate 2, a claw pole 4 to be shaped placed on the conical support platform 3, a coaxial surrounding plate 5 arranged around the conical support platform 3, a plurality of vertical mounting grooves 6 evenly opened on the inner wall of the surrounding plate 5, the top of the mounting grooves 6 being open, and the plurality of mounting grooves 6 being respectively aligned with the plurality of claws of the claw pole 4, a pressing device for pressing the claws of the claw pole 4 being installed in the mounting grooves 6, a common pushing device being provided on the top of the plurality of pressing devices for simultaneously pushing the plurality of pressing devices to press the plurality of claws of the claw pole 4, a clamping device being provided between each pair of adjacent claws of the claw pole 4, the clamping device being installed on the side of the conical support platform 3 for keeping the distance between the two adjacent claws the same, a cavity being provided at the center of the conical support platform 3, and a drive assembly for driving the plurality of clamping devices to move synchronously being installed in the cavity; The automotive generator claw pole shaping device also includes a U-shaped frame 7, a first electric push rod 8, and a pressure ring 9; the U-shaped frame 7 is fixedly connected to the top of the base 1, and the surrounding plate 5 is located in the inner area of ​​the U-shaped frame 7; there are two first electric push rods 8, which are symmetrically and vertically fixedly connected to the inner wall of the top of the U-shaped frame 7; the pressure ring 9 is horizontally fixedly connected between the bottom ends of the two first electric push rods 8, and the pressure ring 9 is coaxial with the conical support platform 3; the bottom of the pressure ring 9 can maintain contact with the top of the claw pole 4. During the shaping operation of the claw pole 4, the claw pole 4 to be shaped is placed on the conical support platform 3. Then, the direction of the claw pole 4 is adjusted so that the multiple claws of the claw pole 4 are aligned with the multiple extrusion devices. After the adjustment is completed, as the first electric push rod 8 extends downward, the pressure ring 9 can first press the claw pole 4 from the top. After the claw pole 4 is pressed, as the push device presses down on the multiple extrusion devices, the multiple extrusion devices can simultaneously press the multiple claws of the claw pole 4, thereby completing the side shaping operation of the claw pole 4. Subsequently, as the drive component operates, the two adjacent clamping devices can cooperate with each other to press the claws of the claw pole 4 along the conical surface of the conical support platform 3. Thus, when the claws of the claw pole 4 are deviated, the pressing action of the two clamping devices can make the claws of the claw pole 4 more regular, and finally, the distance between the two adjacent claws of the claw pole 4 can be kept the same. In conjunction with the pressing action of the extrusion device on the claws, the entire claw pole 4 can be better shaped, improving the finished product quality of the claw pole 4.

[0020] like Figures 2 to 6As shown, the extrusion device includes a push block 10, an extrusion plate 11, a slider 12, a support block 13, and a return spring 14. The push block 10 is slidably installed in the mounting groove 6 in the vertical direction. The side of the push block 10 near the conical support platform 3 is inclined from top to bottom away from the conical support platform 3. The extrusion plate 11 is vertically arranged on the side of the push block 10 near the conical support platform 3, and the side of the extrusion plate 11 near the claw pole 4 can be completely fitted with the claw of the claw pole 4. The slider 12 is fixedly connected to the extrusion plate 11 and is slidably installed on the inclined surface of the push block 10. The sliding direction of the slider 12 is parallel to the inclined surface direction of the push block 10. The support block 13 is fixedly connected to the top of the mounting plate 2, and the top of the support block 13 is slidably connected to the bottom of the extrusion plate 11 and the bottom of the slider 12. The return spring 14 is connected between the bottom of the push block 10 and the inner wall of the bottom of the mounting groove 6. The pushing device includes a mounting ring 15, a pressure block 16, and a second electric push rod 17. The mounting ring 15 is horizontally set on the top of the enclosure 5 and is coaxial with the conical support platform 3. The number of pressure blocks 16 corresponds one-to-one with the number of push blocks 10. Multiple pressure blocks 16 are evenly fixedly connected to the bottom of the mounting ring 15, and the bottom of multiple pressure blocks 16 can keep in contact with the top of multiple push blocks 10 in the vertical direction. There are two second electric push rods 17. The two second electric push rods 17 are symmetrically and vertically fixedly connected to the top of the mounting ring 15, and the top of the second electric push rod 17 is fixedly connected to the inner side wall of the U-shaped frame 7. After the claw pole 4 is placed on the conical support platform 3, it is rotated for adjustment so that the multiple claws of the claw pole 4 are aligned with the multiple extrusion plates 11 one by one. After adjustment, as the first electric push rod 8 extends downward, the pressure ring 9 can first press the claw pole 4 from the top. Then, as the second electric push rod 17 extends, the mounting ring 15 can drive the pressure block 16 to move downward. When the bottom of the pressure block 16 contacts the top of the push block 10, as the second electric push rod 17 continues to extend, the push block 10 can extrude the pressure block 16. Under pressure, it moves downward, and as the push block 10 moves downward, the return spring 14 can be compressed, and the pressing plate 11 can move along the top of the support block 13 towards the claw pole 4 under the pressing action of the push block 10 on the slider 12. When the pressing plate 11 contacts the claw of the claw pole 4, as the pressing block 16 continues to press the push block 10 downward, the multiple claws of the claw pole 4 can be completely pressed together with the conical surface of the conical support platform 3 under the joint pressing action of the multiple pressing plates 11, thereby completing the side shaping operation of the claw pole 4. After the shaping is completed, as the first electric push rod 8 and the second electric push rod 17 are reset in succession, the push block 10 can move upward under the push of the reset spring 14. As the push block 10 moves upward, the pressing plate 11 can separate from the side of the claw pole 4 under the action of the push block 10 on the slider 12. Then the shaped claw pole 4 can be removed from the conical support platform 3.

[0021] like Figure 4 and Figure 5 As shown, the clamping device includes an arc panel 18, a limiting block 19, a connecting rod 20, and a connecting sleeve 21. The arc panel 18 is slidably attached to the side of the conical support platform 3, and the width of the arc panel 18 gradually increases from top to bottom. The limiting block 19 is fixedly connected to the side of the arc panel 18 near the conical support platform 3, and the side of the conical support platform 3 is provided with a limiting groove matching the limiting block 19 along the inclined direction of its conical surface. The limiting block 19 is slidably installed in the limiting groove. A connecting hole 22 is provided through the limiting groove and the cavity of the conical support platform 3. The connecting rod 20 is fixedly connected to the limiting block 19, and the connecting rod 20 is horizontally inserted into the connecting hole 22. The connecting sleeve 21 is slidably sleeved on the end of the connecting rod 20 away from the limiting block 19, and the connecting sleeve 21 is inserted into the connecting hole 22. The width of the connecting sleeve 21 matches the width of the connecting hole 22. The drive assembly includes a drive rod 23, a motor 24, and a bushing 25. The drive rod 23 is vertically rotatably inserted into the bottom center of the conical support platform 3 and the mounting plate 2. The top end of the drive rod 23 is rotatably connected to the top inner wall of the cavity. The motor 24 is drivenly connected to the bottom end of the drive rod 23. The bushing 25 is threaded onto the drive rod 23, and the side of the bushing 25 is fixedly connected to multiple connecting sleeves 21. With the clamping device in place, the claw pole 4 is placed on the conical support platform 3 and its position is adjusted so that each claw corresponds to one of the multiple extrusion plates 11. Then, as the first electric push rod 8 drives the pressure ring 9 to move downward, the pressure ring 9 can press the claw pole 4 onto the conical support platform 3. Next, the second electric push rod 17 can extend, thereby driving the mounting ring 15 to move downward. When the pressure block 16 at the bottom of the mounting ring 15 presses the extrusion plate 11 and the claw pole 4 completely by squeezing the push block 10, the motor 24 can be started to drive the drive rod 23 to rotate. As the drive rod 23 rotates, the bushing 25 can pass through multiple connecting sleeves 21 and connecting rods under the action of the drive rod 23. The connecting rod 20 drives multiple arc panels 18 to move upward along the side of the conical support platform 3. During this process, the connecting rod 20 can adaptively move into the connecting sleeve 21 in the horizontal direction. As the multiple arc panels 18 move upward synchronously, two adjacent arc panels 18 can simultaneously squeeze the claws of the claw pole 4 from the side. Thus, when the claws of the claw pole 4 are deviated, the squeezing action of the two arc panels 18 along the conical surface of the conical support platform 3 can make the claws of the claw pole 4 more regular. Finally, the distance between two adjacent claws of the claw pole 4 can be kept the same. In addition, with the squeezing action of the squeezing plate 11 on the claws, the entire claw pole 4 can be better shaped, improving the finished product quality of the claw pole 4.

[0022] like Figures 1 to 7As shown, a lifting rod 26 is slidably inserted through the top center of the claw pole 4, and the diameter of the lifting rod 26 is smaller than the inner diameter of the pressure ring 9. A circular support block 27 is fixedly connected to the bottom end of the lifting rod 26 to support the claw pole 4. A groove 28 matching the support block 27 is opened at the top center of the conical support platform 3, and when the support block 27 is inserted into the groove 28, the top of the support block 27 is flush with the top of the conical support platform 3. When shaping the claw electrode 4, due to the depth of the surrounding plate 5 and the small size of the claw electrode 4, it is inconvenient to place the claw electrode 4 on the conical support platform 3 or remove the claw electrode 4 from the conical support platform 3. At this time, by providing a lifting rod 26, when the claw electrode 4 is placed on the conical support platform 3, the claw electrode 4 can be sleeved on the lifting rod 26, thereby lifting the claw electrode 4 through the support block 27. Then, the claw electrode 4 can be placed on the conical support platform 3 through the lifting rod 26, and it is also more convenient to adjust the claw electrode 4 so that its claw is better aligned with the extrusion plate 11. After shaping, the claw electrode 4 can also be easily removed from the conical support platform 3 through the lifting rod 26, improving the convenience of removing the claw electrode 4.

[0023] like Figures 1 to 3 As shown, an adjustment assembly for adjusting the position of the push block 10 is sleeved on the outer side of the enclosure 5. The adjustment assembly includes a fixing ring 29, an adjustment rod 30, a safety clutch gear 31, and an adjustment ring 32. The fixed ring 29 is slidably sleeved on the surrounding plate 5. The number of adjusting rods 30 corresponds one-to-one with the number of multiple push blocks 10. Multiple adjusting rods 30 are horizontally and vertically rotatably inserted into the fixed ring 29. A strip hole 33 communicating with the mounting groove 6 is opened through the side of the surrounding plate 5 opposite to the adjusting rods 30, and the adjusting rods 30 are inserted through the strip hole 33. The end of the adjusting rod 30 near the push block 10 is horizontally threaded into the push block 10. The safety clutch gear 31 is sleeved on the end of the adjusting rod 30 away from the push block 10. The adjusting ring 32 is rotatably sleeved on the fixed ring 29, and the bottom of the adjusting ring 32 is evenly provided with teeth. The teeth mesh with the safety clutch gear 31. Several levers 34 are evenly fixedly connected to the outside of the fixed ring 29, which are used to drive the adjusting ring 32 to rotate through the levers 34. During the pressing process of the extrusion plate 11 on the claw pole 4, due to the difference in thickness between the claws of the claw pole 4, the extrusion plates 11 may experience varying degrees of wear due to uneven force during long-term use. Consequently, during the subsequent pressing and shaping operation of the claw pole 4, the extrusion plates 11 cannot apply pressure evenly to the claws of the claw pole 4. At this time, by setting an adjustment component, after the claw pole 4 to be shaped is placed on the conical support platform 3, as the extrusion plate 11 is pressed against the side of the claw pole 4 under the action of the push block 10, the second electric push rod 17 stops extending. Then, the adjusting ring 32 is actuated by the toggle block 34. As the adjusting ring 32 rotates, it can drive multiple adjusting rods 30 to rotate synchronously through the transmission action of multiple safety clutch gears 31. During this process, if the extrusion plate 11 is already pressed against the claw pole 4, At this point, as the adjusting ring 32 rotates, the safety clutch gear 31 corresponding to the pressing plate 11 can idle, thus no longer driving the adjusting rod 30 to rotate. If the pressing plate 11 is not tightly attached to the claw pole 4, as the adjusting ring 32 rotates, the adjusting rod 30 can push the push block 10 and the pressing plate 11 together towards the claw pole 4 under the drive of the corresponding safety clutch gear 31 until the pressing plate 11 is attached to the claw pole 4. Then, the corresponding safety clutch gear 31 also starts to idle. When all the pressing plates 11 are attached to the claw pole 4 under the action of the adjusting rod 30, the position adjustment of all the pressing plates 11 can be completed. This ensures that in the subsequent shaping operation, all the pressing plates 11 can generate sufficient pressing force on the claw of the claw pole 4 under the action of the corresponding push block 10, thereby improving the shaping effect of the claw pole 4.

[0024] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
