DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] This utility model provides two technical solutions:

[0023] Figure 1-Figure 4The first embodiment is shown: a DC motor rotor winding device, including a workbench 1 and a rotor body 5, the workbench 1 is provided with a winding mechanism for winding the rotor body 5, the winding mechanism comprising: a rotating assembly 2, arranged on the top of the workbench 1, the rotating assembly 2 including a movable plate 26, the top of the movable plate 26 near the edge is fixedly connected to two limit blocks 27; a pressing assembly 3, arranged on the top of the workbench 1; a reciprocating assembly 4, arranged on the top of the workbench 1, the reciprocating assembly 4 including two mounting brackets fixedly mounted on the top of the workbench 1 41. A reciprocating screw rod 42 is provided for rotation inside the mounting frame 41. The reciprocating screw rod 42 is driven by the second motor 410 and drives the lifting block 43 to make reciprocating motion up and down through the transmission of the synchronous wheel 47 and the synchronous belt 48, so that the lead cylinder 45 guides the winding to realize reciprocating winding on the rotor body 5 to ensure the uniformity of the winding. The outer wall of the reciprocating screw rod 42 is threadedly installed with the lifting block 43, and the outer surface of the lifting block 43 is slidably penetrated by the lead cylinder 45. The lead cylinder 45 can guide the winding to be accurately wound on the rotor body 5 to ensure the accuracy and quality of the winding.

[0024] The rotating assembly 2 also includes a first motor 21 fixedly mounted on the bottom of the workbench 1. The intermittent forward and reverse rotation of the first motor 21 provides power for the rotation of the rotor body 5, drives the support platform 22 to rotate, and then drives the entire rotating assembly and the rotor body 5 to rotate, realizing circumferential motion during the winding process. The output end of the first motor 21 movably passes through the bottom of the workbench 1 and extends upward. The output end of the first motor 21 is fixedly mounted with a support platform 22. A spring 23 is symmetrically mounted on the top of the support platform 22. The spring 23 can enable the support plate 24 to move upward and reset without force. A support plate 24 is fixedly connected between the top ends of the two springs 23. A sliding column is symmetrically mounted on the bottom of the support plate 24. The outer wall of the sliding column 25 slides through the top of the support platform 22 and extends downward. The bottom end of the sliding column 25 is fixedly connected to the top surface of the movable plate 26. The support plate 24 and the movable plate 26 are connected by the sliding column 25 to ensure stable movement of the support plate 24 in the vertical direction and transmit the pressure exerted on the support plate 24 to the movable plate 26.

[0025] The clamping assembly 3 includes a fixing frame 31 fixedly mounted on the top of the workbench 1 near the rear side, and a cylinder 32 is fixedly mounted on the top of the fixing frame 31. The telescopic end of the cylinder 32 slides through the top of the fixing frame 31 and extends downward. The telescopic end of the cylinder 32 is rotatably provided with a pressure plate 33, and a pressure column 34 is fixedly mounted on the bottom surface of the pressure plate 33. The bottom surface of the pressure column 34 contacts the bottom surface of the support plate 24.

[0026] Figure 1-Figure 4A second embodiment is shown, the main difference from the first embodiment is that a limiting column 44 that slides through the lifting block 43 is fixedly installed inside the mounting frame 41, and the movement direction of the lifting block 43 is limited by the limiting column 44 to ensure that it can only move up and down along the predetermined track. An electric push rod 46 is fixedly installed on the top of the lifting block 43, and the telescopic end of the electric push rod 46 is fixedly connected to the lead tube 45. The position of the lead tube 45 can be adjusted by the electric push rod 46 so that it can adapt to rotor bodies 5 of different sizes and winding requirements.

[0027] The bottom end of the reciprocating screw rod 42 moves through the bottom of the mounting frame 41 and the top of the workbench 1 in sequence and extends downward. A synchronous wheel 47 is fixedly installed on the bottom surface of the reciprocating screw rod 42, and a synchronous belt 48 is provided between the two synchronous wheels 47.

[0028] The reciprocating assembly 4 further includes a bracket 49 fixedly mounted on the bottom of the workbench 1 , a second motor 410 is fixedly mounted on the inner bottom of the bracket 49 , and an output end of the second motor 410 is fixedly connected to the bottom surface of one of the synchronous wheels 47 .

[0029] At the same time, the contents not described in detail in this specification belong to the existing technology well known to those skilled in the art.

[0030] During operation, the rotor body 5 is placed on the support platform 22, and the limit blocks 27 on both sides of the movable plate 26 are stuck in the corresponding protrusions on the winding groove of the rotor body 5, so that the direction of the rotor body 5 can be limited, thereby improving the positioning accuracy of the rotor body 5. Afterwards, the cylinder 32 is started, and its telescopic end pushes the pressure plate 33 and the pressure column 34 to move downward. The pressure plate 33 presses the rotor body 5. At the same time, the bottom surface of the pressure column 34 contacts the support plate 24 and squeezes the support plate 24 downward. The movable plate 26 is pushed downward by the sliding column 25 to move it away from the rotor body 5, preventing the movable plate 26 and the limit blocks 27 from interfering with the rotor body 5 during the subsequent winding process. Afterwards, the second motor 410 is started, and its output end drives one of The synchronous wheel 47 rotates, and through the transmission of the synchronous belt 48, the two synchronous wheels 47 rotate synchronously, thereby driving the reciprocating screw rods 42 on both sides to rotate. The lifting block 43 on the reciprocating screw rod 42 makes an up and down reciprocating motion along the limit column 44 under the action of the thread, so that the lead barrels 45 on both sides make an up and down reciprocating motion synchronously, and, in conjunction with the forward and reverse rotation of the first motor 21, the angle of the rotor body 5 is adjusted, so that the lead barrel 45 rotates accordingly around the protrusion of the winding groove of the rotor body 5. At the same time, the electric push rod 46 on the top of the lifting block 43 can adjust the position of the lead barrel 45, so that the lead barrel 45 guides the winding to accurately perform reciprocating winding on the rotor body 5, and the winding is performed simultaneously on both sides of the rotor body 5, thereby greatly improving the work efficiency.
