Technical Field
[0001] This invention relates to the field of motor coil winding technology, and in particular to a lifting device and winding equipment. Background Technology

Therefore, it cannot adapt to the winding needs of various specifications of coils and is inconvenient to use. Summary of the Invention

The eccentricity adjustment body is connected to the eccentric body. The worm gear is fitted onto the eccentricity adjustment body.

[0013] More preferably, the eccentricity adjustment body has a constant velocity spiral groove around the third axis, and the eccentric body has multiple arc-shaped protrusions that cooperate with the constant velocity spiral groove; the Archimedean spiral, also known as the constant velocity spiral, is named after the Greek mathematician Archimedes of the third century BC; the Archimedean spiral is the trajectory produced by a point moving away from a fixed point at a constant velocity while rotating around that fixed point at a constant angular velocity. Archimedes described this in his book "The Spiral," and the shape of the constant velocity spiral groove of the present invention is an Archimedean spiral.
[0014] The second drive assembly drives the worm to rotate through the docking assembly, and the worm drives the eccentricity adjustment body to rotate around the third axis through the worm wheel, so that the eccentric body can move closer to or away from the first axis along the constant velocity helical groove through the arc-shaped protrusion.
[0015] More preferably, the rotating body includes a rotating shaft connected to the first driving component and a rotating shell coaxially connected to the rotating shaft;
[0016] The rotating shaft has a first through hole extending along the first axis;
[0017] The rotating shell has a cavity inside, and the rotating shell has a first end and a second end.

[0028] When the winding speed increases, the connecting rod will generate high-frequency vibration due to the change in the position of the center of inertia. By making the inertia of the rotating body greater than that of the connecting rod, the proportion of the connecting rod in the total moment of inertia can be reduced, thereby reducing high-frequency vibration.
[0029] The present invention also provides a winding device, which includes any of the above-mentioned lifting devices.
[0030] Compared with the prior art, the lifting device of this invention has the following advantages: the rotating body can drive the eccentric body to move along a circular trajectory around the first axis. The connecting rod and connecting shaft can convert the circular trajectory into the vertical stroke of the lifting component. Furthermore, the eccentricity adjustment mechanism can drive the eccentric body closer to or further away from the first axis, changing the diameter of the circular trajectory and thus altering the vertical stroke of the lifting component. Therefore, the lifting device of this invention, while converting the rotational motion of the motor into linear lifting motion, also has the function of adjustable vertical stroke. Winding equipment using the lifting device of this invention has the advantages of adapting to the winding needs of various coil specifications and ease of use. Attached Figure Description

[0068] like Figure 1-5 As shown, a preferred embodiment of the present invention provides a lifting device comprising a crank-connecting rod mechanism 1, a lifting mechanism 2, a first drive assembly 3, and an eccentricity adjustment mechanism 4.
[0069] See Figure 6 and Figure 7 The crank-connecting rod mechanism 1 includes a rotating body 11, an eccentric body 12, and a connecting rod 13. The central axis of the rotating body 11 is a first axis. The eccentric body 12 is connected to the rotating body 11 and can move around the first axis along a circular trajectory. One end of the connecting rod 13 has a first connecting hole 131 and the other end has a second connecting hole 132. The first connecting hole 131 is rotatably connected to the eccentric body 12.
[0070] See Figure 15 and Figure 16 The lifting mechanism 2 includes a connecting shaft 21 and a lifting assembly 22. One end of the connecting shaft 21 is rotatably connected to the second connecting hole 132, and the other end is rotatably connected to the lifting assembly 22. The lifting assembly 22 includes a lifting body 221 and a plurality of guide rods 222. The lifting body 221 is rotatably connected to the connecting shaft 21. The lifting body 221 has guide holes 2211 that correspond one-to-one with the guide rods 222. The guide rods 222 pass through the guide holes 2211 from top to bottom.
[0071] See Figure 3The first driving component 3 is connected to the rotating body 11 and can drive the rotating body 11 to rotate around the first axis.
[0072] See Figure 5 , Figure 18 and Figure 23 The eccentricity adjustment mechanism 4 is connected to the eccentric body 12 and can drive the eccentric body 12 to move closer to or away from the first axis.
[0073] Based on this technical solution, the rotating body 11 can drive the eccentric body 12 to move along a circular trajectory around the first axis. Then, through the connecting rod 13 and the connecting shaft 21, the circular trajectory can be converted into the vertical stroke of the lifting component 22. Furthermore, through the eccentricity adjustment mechanism 4, the eccentric body 12 can be driven to move closer to or further away from the first axis, thereby changing the diameter of the circular trajectory and thus changing the vertical stroke of the lifting component 22. Therefore, the lifting device of the present invention, based on the ability to convert the rotational motion of the motor into linear lifting motion, has the function of adjustable vertical stroke.
[0074] See Figure 1-4 The lifting device further includes a housing 10, the outer wall of which is connected to a mounting plate 20, and the bottom of the mounting plate 20 has a damping spring shock absorber 30. The first drive assembly 3 includes a drive motor 31 and a drive pulley 32 coaxially connected to the output shaft of the drive motor 31. The drive pulley 32 is connected to the driven pulley 117 via a belt. The first drive assembly 3 is used to drive the rotating body 11 to rotate around the first axis.
[0075] See Figure 7 The eccentric body 12 is rotatably connected to the first connecting hole 131 via a bearing 1000, and the connecting shaft 21 is rotatably connected to the lifting assembly 22 via a bearing 1000.
[0076] See Figures 6-14 The rotating body 11 provided in this embodiment of the invention includes a rotating shaft 111 connected to the first driving component 3 and a rotating shell 112 coaxially connected to the rotating shaft 111.
[0077] The rotating body 11 further includes an outer bearing 113, an outer spacer 114, a bearing cover 115, a worm gear seat 116, and a driven pulley 117. The outer bearing 113, the outer spacer 114, and the bearing cover 115 are all fitted onto the outer wall of the rotating shaft 111. The worm gear seat 116 is coaxially connected to the rotating shaft 111. The worm gear seat 116 has a bearing cover 115 for mounting the worm 413. The driven pulley 117 is coaxially connected to the worm gear seat 116.
[0078] The sum of the inertia of the rotating shaft 111 and the rotating shell 112 is greater than the inertia of the connecting rod 13, which can reduce the proportion of the connecting rod 13 in the total motion inertia and reduce high-frequency vibration.
[0079] Specifically, the moment of inertia of the rotating shaft 111 is greater than that of the connecting rod 13, and the moment of inertia of the rotating shell 112 is greater than that of the connecting rod 13.
[0080] The rotating shaft 111 has a first through hole 1111 extending along the first axis.
[0081] The rotating shell 112 has a cavity 1121 inside. The rotating shell 112 has a first end and a second end. The first end has a second through hole 1122 extending along the first axis, and the second end has a third through hole 1123 extending along the first axis. The first through hole 1111, the second through hole 1122, the cavity 1121 and the third through hole 1123 are connected in sequence. The second end has a strip-shaped hole 1124 extending radially along the rotating shell 112. One end of the strip-shaped hole 1124 extends to the third through hole 1123 and the other end extends to the edge of the rotating shell 112 and is open. Both sides of the strip-shaped hole 1124 have guide grooves 1125.
[0082] Specifically, the rotating shell 112 includes a front cover and a rear cover detachably connected to the front cover; a cavity 1121 is formed between the front cover and the rear cover, the front cover has a second through hole 1122, and the rear cover has the third through hole 1123 and the strip hole 1124.
[0083] The eccentric body 12 has a plurality of arc-shaped protrusions 121 that cooperate with the constant velocity spiral groove 4113, and the two sides of the eccentric body 12 have guide strips 122 that cooperate with the guide groove 1125.
[0084] Preferably, the eccentric body 12 includes an eccentric body and an eccentric shaft connected to the eccentric body. The end of the eccentric body facing the rotating body 11 has the arc-shaped protrusion 121, and the two sides of the eccentric body have the guide rails 122. The eccentric shaft is rotatably connected to the connecting rod 13.
[0085] See Figures 15-17 The lifting assembly 22 provided in this embodiment of the invention includes a lifting body 221 and a plurality of guide rods 222. The lifting body 221 is rotatably connected to the connecting shaft 21. The lifting body 221 has guide holes 2211 that correspond one-to-one with the guide rods 222.

[0087] Specifically, the lifting body 221 has a guide hole 2212 through which the guide rod 100 of the winding device passes from top to bottom and is rotatably connected to the guide rod 100. In the winding device, the rotational motion of the rotating body 11 is converted into the linear lifting motion of the lifting body 221 by the crank-connecting rod mechanism 1 and the lifting mechanism 2. The lifting body 221 then drives the guide rod 100 to rise or fall, completing the up and down stroke of the winding device regarding the coil winding.
[0088] The lifting assembly 22 also includes a guide rod seat 23, which is fixed inside the housing 10 and is fixedly connected to the upper and lower ends of the guide rod 222.
[0089] See Figures 18-22 ,and Figure 24 The eccentricity adjustment mechanism 4 provided in this embodiment of the invention includes an eccentricity adjustment component 41, a connecting component 42, and a second driving component 43; the eccentricity adjustment component 41 is connected to the eccentric body 12, and the connecting component 42 is connected to the eccentricity adjustment component 41 and the second driving component 43 respectively.
[0090] The connecting component 42 includes a first docking member 421 and a second docking member 422. The first docking member 421 is fixedly connected to the eccentricity adjustment component 41. The central axis of the first docking member 421 is the second axis. The second docking member 422 is fixedly connected to the second driving component 43. The second driving component 43 can drive the second docking member 422 to dock and fix with the first docking member 421 and drive the first docking member 421 to rotate around the second axis.
[0091] By employing the first docking member 421 and the second docking member 422, the second driving component 43 can drive the second docking member 422 to dock and fix with the first docking member 421 or to detach from it, thereby determining whether to use the eccentricity adjustment mechanism 4 to adjust the coil specifications according to actual needs; when the winding device is in the winding stroke, the first docking member 421 and the second docking member 422 are in a detached state; when the winding stroke ends and the coil specifications need to be changed, the second driving component 43 drives the second docking member 422 to approach the first docking member 421 and dock and fix it with the first docking member 421, so that the second driving component 43 can drive the first docking member 421 to dock and fix it through the second docking member 422;
[0092] More specifically, the first docking member 421 has a rectangular protrusion, the second docking member 422 has a rectangular groove that mates with the rectangular protrusion, and the second driving component 43 drives the second docking member 422 to approach the first docking member 421 and causes the rectangular protrusion to engage in the rectangular groove, so that the second driving component 43 can drive the first docking member 421 to rotate about the third axis.
[0093] Specifically, the eccentricity adjustment assembly 41 includes an eccentricity adjustment body 411, a worm gear 412, and a worm 413. The central axis of the eccentricity adjustment body 411 is a third axis. The eccentricity adjustment body 411 is connected to the eccentric body 12.

The eccentricity adjustment body 411 has a constant velocity helical groove 4113 around the third axis, and the constant velocity helical groove 4113 cooperates with the arc-shaped protrusion 121.
[0094] More specifically, the eccentricity adjustment body 411 includes an adjustment shaft 4111 and an adjustment disc 4112 coaxially connected to the adjustment shaft 4111; the adjustment shaft 4111 is fitted and fixed to the worm gear 412, and the adjustment disc 4112 has the constant velocity helical groove 4113.
[0095] The second drive assembly 43 drives the worm 413 to rotate through the docking assembly 42. The worm 413 drives the eccentricity adjustment body 411 to rotate around the third axis through the worm wheel 412, so that the eccentric body 12 can move closer to or away from the first axis through the arc-shaped protrusion 121 along the constant velocity helical groove 4113.
[0096] The second drive assembly 43 includes a rotary motor 431 and a telescopic member 432. The second docking member 422 is coaxially connected to the output shaft of the rotary motor 431. The telescopic member 432 is connected to the rotary motor 431 and can drive the rotary motor 431 to move closer to or away from the first docking member 421.
[0097] Specifically, the rotary motor 431 is a servo motor, and the telescopic device 432 is a cylinder.
[0098] Specifically, the second drive assembly 43 further includes a fixed base 433, a linear guide rail 434, and a mounting base 435.

The rotary motor 431 is connected to the linear guide rail 434 and can move along the linear guide rail 434. The output end of the telescopic device 432 is fixedly connected to the rotary motor 431 through the mounting base 435. The second drive assembly 43 is fixedly mounted to the housing 10 through the fixed base 433.
[0099] See Figure 23 After the eccentricity adjustment body 411 is assembled with the rotating body 11, the adjustment shaft 4111 is rotatably connected to the inner wall of the first through hole 1111. One end of the adjustment shaft 4111 extends outside the first through hole 1111 and is fixedly fitted with the worm gear 412, while the other end extends into the cavity 1121 and is connected to the adjustment disc 4112.
[0100] See Figure 25 The present invention also provides a winding device, which includes a guide rod 100, a swing device 200, a wire pulling device 300, a clamping device 400, a frame 500, and a lifting device 600.

[0102] In summary, the lifting device provided in this embodiment of the invention has the following beneficial effects:
[0103] 1. By using the eccentric body 12, connecting rod 13, connecting shaft 21 and guide rod 222, the rotational motion of the rotating body 11 can be converted into the linear lifting motion of the lifting body 221.
[0104] 2. By employing the eccentricity adjustment mechanism 4, which is connected to the eccentric body 12 and can drive the eccentric body 12 closer to or further away from the first axis, the diameter of the circular trajectory of the eccentric body 12 can be changed, thereby changing the up-and-down stroke of the lifting body 221.
[0105] 3. By using the first docking part 421 and the second docking part 422, it can be decided whether to use the eccentricity adjustment mechanism 4 to adjust the coil specifications according to actual needs.
[0106] 4. By using the eccentricity adjustment body 411, worm gear 412 and worm 413, the rotation of the first docking member 421 around the third axis can be converted into the rotation of the eccentricity adjustment body 411 around the first axis.
[0107] 5. By using the constant velocity spiral groove 4113 and the arc-shaped protrusion 121, the arc-shaped protrusion 121 can be moved along the constant velocity spiral groove 4113 by rotating the eccentricity adjustment body 411, thereby allowing the eccentric body 12 to move closer to or further away from the first axis along the trajectory of the constant velocity spiral groove 4113 via the arc-shaped protrusion 121.
[0108] 6. By sequentially connecting the first through hole 1111, the second through hole 1122, the cavity 1121, and the third through hole 1123, and employing a strip hole 1124, a guide groove 1125, a guide strip 122, an adjusting shaft 4111, and an adjusting disc 4112, the guide groove 1125 and the guide strip 122 can guide the eccentric body 12 as it approaches or moves away from the first axis along the constant velocity spiral groove 4113 via the arc-shaped protrusion 121, thereby enabling the eccentric body 12 to approach or move away from the first axis in the radial direction of the rotating shell 112.
[0109] 7. By using the rotary motor 431 and the telescoping device 432, the eccentric body 12 can automatically move closer to or further away from the first axis.
[0110] 8. The front and rear covers are removable, which facilitates the installation and removal of the rotating body 11 and the eccentricity adjustment body 411.
[0111] 9. By adopting a method in which the sum of the inertia of the rotating shaft 111 and the rotating shell 112 is greater than the inertia of the connecting rod 13, high-frequency vibration can be reduced, which is beneficial to improving the winding speed of the winding equipment.
