In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] Next, refer to Figures 1-7 to describe the specific structure of the motor coil winding machine according to the embodiment of the present utility model.

[0037] The present utility model discloses a motor coil winding machine. Refer to Figures 1-2As shown in the figure, the motor coil winding machine of this embodiment includes a rotary drive member 100 and a clamping mechanism 200. The rotary drive member 100 has a rotating shaft 110. A counter 300 is provided on the rotary drive member 100. The counter 300 is used to detect the number of rotations of the rotating shaft 110. The clamping mechanism 200 is connected to the rotating shaft 110 and can rotate under the drive of the rotary drive member 100. The clamping mechanism 200 is used to clamp the component 10 to be wound. The clamping mechanism 200 includes a clamping bracket 210, a lead screw 220, and two clamping members 230. The clamping bracket 210 is connected to the rotating shaft 110. The lead screw 220 is rotatably provided on the clamping bracket 210. The two clamping members 230 are threadedly connected to the lead screw 220. When the lead screw 220 rotates, it can drive the two clamping members 230 to move in a direction approaching or away from each other.

[0038] It can be understood that since the distance between the two clamping members 230 can be adjusted when the lead screw 220 rotates, during the actual working process, according to the size of the component 10 to be wound, the distance between the two clamping members 230 can be adjusted by rotating the lead screw 220, so that the clamping mechanism 200 can clamp components 10 to be wound with different specifications. After clamping, the wire is pre-wound around the component 10 to be wound, and starting the rotary drive member 100 can realize winding. Thus, the motor coil winding machine of this embodiment can be used for stator winding with different specifications, saving the mold cost, reducing the use cost, and expanding the applicable range. At the same time, since the counter 300 is provided on the rotary drive member 100 and the counter 300 is used to detect the number of rotations of the rotating shaft 110, during the actual working process, the number of turns of the coil can also be monitored in real time through the counter 300, so as to realize precise control of the number of winding turns.

[0039] Optionally, the rotary drive member 100 is a permanent magnet motor. Of course, in other embodiments of the present invention, the rotary drive member 100 can also be selected according to actual needs to be other drive structures that can realize the output of rotary motion.

[0040] Reference Figure 4 and Figure 5As shown, the clamping bracket 210 includes a base 211 and two baffles 212. The base 211 is connected to the rotating shaft 110. The two baffles 212 are installed at both ends of the base 211. Each baffle 212 is provided with a rotating hole. Both ends of the lead screw 220 respectively have rotating sections 221 that fit into the rotating holes, and bearings 400 are sleeved on the rotating sections 221. It can be understood that on the one hand, the two baffles 212 serve as the rotating support members of the lead screw 220, which can ensure the stable support of the lead screw 220. And because the bearings 400 are sleeved on the rotating sections 221, the friction between the rotating sections 221 and the baffles 212 can be reduced, ensuring that the wear of both the lead screw 220 and the baffles 212 is small when the lead screw 220 rotates, thereby extending the working life of the lead screw 220 and the baffles 212. On the other hand, the two baffles 212 can also serve as a blocking structure. During the actual working process, when the lead screw 220 rotates to drive the two clamping members 230 to move away from each other, when the clamping members 230 abut against the baffles 212, they will no longer continue to move, thus avoiding the phenomenon that the clamping members 230 come off the lead screw 220.

[0041] Reference Figure 4 and Figure 7 As shown, at least one end of the lead screw 220 extends out of the baffle 212, and the part of the lead screw 220 that extends out of the baffle 212 forms a square shaft section 222, and the square shaft section 222 is used to connect to an external driving structure. It can be understood that during the actual working process, since it is necessary to rotate the lead screw 220 to adjust the distance between the two clamping members 230, and the part of the lead screw 220 that extends out of the baffle 212 forms a square shaft section 222, and the square shaft section 222 is used to connect to an external driving structure, which can very conveniently drive the lead screw 220 to rotate, thereby facilitating the adjustment of the distance between the two clamping members 230.

[0042] Optionally, in a specific embodiment of the present invention, the external driving structure is a driving motor; in an alternative embodiment, the square shaft section 222 can be connected to a sleeve, and the lead screw 220 can also be driven to rotate by manually rotating the sleeve. Of course, in other embodiments of the present invention, the external driving structure can also be selected according to actual needs to be other structures, not limited to the above description.

[0043] Reference Figure 3As shown, a first mounting hole 2111 is provided on the base 211, and a second mounting hole 111 corresponding to the first mounting hole 2111 is provided on the rotating shaft 110; a connecting member 500 passes through the first mounting hole 2111 and is connected to the second mounting hole 111 to mount the base 211 on the rotating shaft 110. It can be understood that during the actual assembly process, the base 211 is fitted to the end face of the rotating shaft 110, and the first mounting hole 2111 and the second mounting hole 111 are arranged correspondingly. Then, the connecting member 500 passes through the first mounting hole 2111 and is connected to the second mounting hole 111 to complete the connection between the clamping mechanism 200 and the rotary drive member 100, and the operation is very convenient.

[0044] Optionally, the first mounting hole 2111 is a clearance hole, the second mounting hole 111 is a threaded hole, and the connecting member 500 is a screw. Thus, the connection stability between the clamping mechanism 200 and the rotating shaft 110 can be improved. Of course, the connecting member 500 can also be a fixed pin, both the first mounting hole 2111 and the second mounting hole 111 are clearance holes, and the fixed pin is in interference fit with the second mounting hole 111. In addition, in other embodiments of the present invention, the base 211 and the rotating shaft 110 can also be connected by other means such as connection keys, welding or couplings, and are not limited to the above limitations.

[0045] Reference Figure 5 And Figure 6 As shown, the clamping mechanism 200 further includes a slide rail 240. The slide rail 240 extends along the axial direction of the lead screw 220 and is mounted on the clamping bracket 210. A tenon head 241 is provided on the slide rail 240, and a mortise groove 231 mating with the tenon head 241 is provided on the clamping member 230. It can be understood that according to the foregoing, the distance between the two clamping members 230 is adjusted by rotating the lead screw 220. If the movement of the clamping member 230 is skewed during the working process, it will cause the clamping member 230 to be stuck relative to the rotating lead screw 220. In this embodiment, a slide rail 240 is added, and a tenon head 241 is provided on the slide rail 240, and a mortise groove 231 mating with the tenon head 241 is provided on the clamping member 230. The cooperation between the mortise groove 231 and the tenon head 241 can limit the sliding direction of the clamping member 230, avoid the phenomenon of skewing of the clamping member 230 during the adjustment process, reduce the occurrence of the phenomenon that the clamping member 230 is stuck relative to the lead screw 220, and thus improve the reliability of the clamping mechanism 200.

[0046] Optionally, the mortise groove 231 is a dovetail groove, and the tenon head 241 is a dovetail head. The cooperation between the dovetail groove and the dovetail head provides high-precision guidance, thereby further avoiding the phenomenon of skewing of the clamping member 230 during the adjustment process. Of course, in other embodiments of the present invention, the structures of the mortise groove 231 and the tenon head 241 can be selected according to actual needs.

[0047] Optionally, the slide rail 240 is made of high-strength material, has excellent wear resistance and long service life, and is suitable for long-term use.

[0048] In another alternative embodiment, a mortise 231 is provided on the slide rail 240, and a tenon 241 that cooperates with the mortise 231 is provided on the clamping member 230.

[0049] Reference Figure 6 As shown, a mating groove 242 is further provided on the slide rail 240, a mating protrusion 232 that fits into the mating groove 242 is provided on the clamping member 230, and the lead screw 220 is threadedly connected to the mating protrusion 232. It can be understood that the cooperation between the mating groove 242 and the mating protrusion 232 can also limit the movement of the clamping member 230 to a certain extent, thereby avoiding the phenomenon that the clamping member 230 is skewed during the adjustment process. Passing the lead screw 220 through the mating protrusion 232 can reduce the thickness of the clamping member 230, which is beneficial to the miniaturized design of the clamping member 230, and thus beneficial to reducing the manufacturing cost of the entire clamping mechanism 200.

[0050] Optionally, the mating groove 242 is provided on the top wall of the tenon 241, and the mating protrusion 232 is provided on the groove wall of the mortise 231. Thus, after the clamping member 230 is installed on the slide rail 240, the movement direction of the clamping member 230 can be limited to the greatest extent, thereby avoiding the phenomenon that the clamping member 230 is skewed during the adjustment process. At the same time, in the thickness direction of the slide rail 240, the lead screw 220 and the tenon 241 have a coincident thickness, thereby reducing the total thickness of the slide rail 240 and the clamping member 230 after the cooperation, which is beneficial to the small-size design of the clamping mechanism 200, and thus beneficial to reducing the manufacturing cost of the entire clamping mechanism 200.

[0051] Reference Figure 7 As shown, the lead screw 220 includes a first threaded section 223, a smooth shaft section 224, and a second threaded section 225 that are sequentially arranged along its axial direction. The first threaded section 223 and the second threaded section 225 have opposite helix directions and are respectively matched with two clamping members 230. It can be understood that by separating the first threaded section 223 and the second threaded section 225 through the smooth shaft section 224, the phenomenon that the two clamping members 230 collide during the adjustment process can be avoided. The opposite helix directions of the first threaded section 223 and the second threaded section 225 can ensure that the two clamping members 230 can move in opposite directions during the rotation of the lead screw 220, thereby realizing the function of adjusting the distance between the two clamping members 230.

[0052] Optionally, the threads on the first threaded section 223 and the second threaded section 225 are both trapezoidal threads with a self-locking function. It can be understood that the self-locking of trapezoidal threads is achieved through the special shape of the threads. In trapezoidal threads, the thread profile is symmetrical, and the upper and lower sides of the thread profile engage with each other to form a structure similar to a lock. When an external force acts on the threaded connection part, due to the engagement of the thread profile, friction will be generated, fastening the threads and preventing the threads from loosening or automatically coming off. Thus, when the lead screw 220 stops rotating, due to the self-locking function of the trapezoidal threads, the clamping member 230 can be ensured to be held in the specified position, thereby realizing the stable clamping of the component to be wound 10 and ensuring the stable progress of the winding process. In addition, the trapezoidal thread has a large contact area and good wear resistance. The threads on the first threaded section 223 and the second threaded section 225 are both trapezoidal threads, which is beneficial to extending the service life of the lead screw 220.

[0053] Reference Figure 1 As shown, the motor coil winding machine further includes a support frame 600. The support frame 600 is used to mount the rotary driving member 100. The rotating shaft 110 passes through the support frame 600. The main body structure of the rotary driving member 100 and the clamping mechanism 200 are respectively located on both sides of the support frame 600. It can be understood that since the motor coil winding machine further includes the support frame 600, during the actual working process, there is no need to mount the rotary driving member 100 on an external support. The support frame 600 can be directly moved to the vicinity of the wire outlet device, the wire is pre-wound onto the component to be wound 10, and then the rotary driving member 100 is started. Thus, the use of the motor coil winding machine is facilitated.

[0054] Optionally, the support frame 600 includes a bottom plate 610, a vertical plate 620 and a reinforcing plate 630. The vertical plate 620 is perpendicular to the bottom plate 610. One end of the vertical plate 620 is connected to the bottom plate 610. The vertical plate 620 is used to mount the rotary driving member 100. The two adjacent side walls of the reinforcing plate 630 are respectively connected to the bottom plate 610 and the vertical plate 620. It can be understood that the bottom plate 610 can ensure the stability of the entire support frame 600, thereby ensuring the stability of the rotary driving member 100 and the clamping mechanism 200. The vertical plate 620 can make the clamping mechanism 200 and the rotary driving member 100 at a specified height, facilitating winding. The reinforcing plate 630 can enhance the strength of the entire support frame 600, reduce the deformation amount of the support frame 600, and extend its service life.

[0055] Optionally, the rotary driving member 100 is fixed to the vertical plate 620 through a fixing member 700. The fixing member 700 includes a bolt and a nut. The bolt passes through the vertical plate 620 and the housing of the rotary driving member 100, and the nut is installed on the bolt. Thus, it is both convenient to install the rotary driving member 100 and can improve the installation stability of the rotary driving member 100.
