Description

Technical Field

[0001] This invention relates to the field of motor stator production equipment, and in particular to a winding drive device for a winding machine. Background Technology

[0002] A winding machine is a mechanical production equipment for embedding coils into the iron core of an electric motor. Automatic winding machines replace manual labor production, improving production efficiency and reducing production costs for motor stator manufacturers. The existing winding machine's drive mechanism is based on a motor driving a lead screw, which in turn drives a pusher to push the copper head or slotted paper into the stator. The drive method is relatively simple.

[0003] Currently, Chinese invention patent CN104201843B discloses a winding drive mechanism for a winding machine. This mechanism includes a main drive screw installed between a mounting base plate and an upper base plate. A main drive motor that drives the main drive screw is installed on the lower base plate. A push rod base plate is connected to the guide post, and the push rod base plate is also connected to the main drive screw. The push rod base plate is connected to a push rod seat base plate, and a push rod constellation is installed on the push rod seat base plate. Paper push rods are evenly distributed on the push rod constellation, and the ends of the paper push rods are connected to an intermediate sleeve. The intermediate sleeve is installed on the upper base plate. The mechanism also includes a guide bar ejection mechanism connected to the upper base plate. A push rod is installed on the push rod base plate, and the push rod passes through the hollow guide bar push rod.

[0004] Although existing winding drive mechanisms can push copper wire ends or copper wires together with slotted paper into the iron core, the existing winding drive structure does not have a well-connected fixing structure to restrict the position of the stator during the winding process. Therefore, the stator is prone to displacement during the winding process, which leads to malfunctions of the winding stator. Summary of the Invention

[0005] The purpose of this invention is to provide a winding drive device for a winding machine, which has the advantage of being able to firmly fix the stator during the winding process, preventing the stator position from shifting, thereby making the winding process smoother and more precise, and improving the production quality of the stator.

[0006] To achieve the above and other related objectives, the present invention provides the following technical solution:

[0007] A wire-inserting drive device for a wire-inserting machine includes an upper base plate and a lower base plate, a connecting screw is provided between the upper base plate and the lower base plate, and a first drive assembly for driving the connecting screw to rotate is provided on the lower base plate;

[0008] The connecting screw is provided with a first pushing component for pushing copper wire into the stator. The first pushing component includes a main board connected to the connecting screw and a copper wire push rod provided on the main board. The main board is provided with a rotating component that drives the copper wire push rod to rotate a certain angle and hooks the end of the copper wire.

[0009] The motherboard is provided with a second pushing assembly, which includes a first lead screw mounted on the motherboard, a mounting plate connected to the first lead screw, and a plurality of slotted paper push rods fixed on the mounting plate; the motherboard is provided with a second driving assembly for driving the first lead screw to rotate.

[0010] The upper base plate is provided with a third pushing assembly for fixing the stator. The third pushing assembly includes a second lead screw connected to the upper base plate, a fixed push plate connected to the second lead screw, and a fixed push rod fixed to the fixed push plate. The upper base plate is provided with a third driving assembly for driving the second lead screw to rotate. The fixed push rod is a hollow tubular structure, and the copper wire push rod is located inside the fixed push rod.

[0011] Several of the aforementioned slotted paper push rods are arranged in a circular pattern outside the fixed push rod.

[0012] Through the above technical solution, the first pushing component is used to simultaneously push the copper wire pusher and the slotted paper pusher, thereby embedding the copper wire or copper wire end and the slotted paper together into the stator, thus reducing the resistance during embedding and improving the smoothness of embedding; the main board is used to support the copper wire pusher, and the main board moves upward on the connecting screw to drive the copper wire pusher to push the copper wire end or copper wire into the stator; the rotating component is used to drive the copper wire pusher to rotate at a certain angle, thereby hooking the copper wire end on the workstation, and the main board continues to move upward to push the copper wire into the stator; the second pushing component is used to adjust the height difference between the copper wire pusher and the slotted paper pusher, exposing the copper wire pusher outside the slotted paper pusher, so that the copper wire pusher can smoothly hook the copper wire and then... During the process of pushing the copper wire into the stator, there is no interference with the slotted paper pusher. The mounting plate is used to fix the slotted paper pusher, which is used to push the slotted paper into the stator. The mounting plate moves up and down on the first screw, thereby exposing the copper wire pusher outside the slotted paper pusher, thus preventing the copper wire pusher from hooking the copper wire end and causing interference. The third pushing assembly is used to fix the stator to be wired. The fixing push plate is used to fix the fixing pusher. The fixing push plate moves up on the second screw, thereby pushing the fixing pusher to insert into the stator and fix the stator. Thus, when the copper wire pusher and the slotted paper pusher push the copper wire and the slotted paper into the stator, the stator position does not shift, thereby making the wire insertion smoother and more precise, and improving the production quality of the stator.

[0013] In one embodiment of the present invention, the rotating assembly includes a cylinder fixed on the motherboard, a rack fixed on the cylinder piston rod, and a gear meshing with the rack and fixed on a copper wire push rod.

[0014] Through the above technical solution, the cylinder drives the rack to reciprocate, thereby driving the gear to rotate and causing the copper wire to rotate and hook the copper wire end.

[0015] In one embodiment of the present invention, a fixed circular plate is fixed on the fixed push plate, and a circular hole for the copper wire push rod to pass through is opened in the middle of the fixed circular plate. A connecting part is coaxially arranged with the circular hole, the connecting part is integrally formed on the fixed circular plate, and the fixed push rod is fixed on the connecting part.

[0016] A number of slots are provided on the fixed circular plate located on the outer side of the connecting part for the passage of the paper push rod.

[0017] Through the above technical solution, the round hole is used to allow the copper wire push rod to pass through, the connecting part is used to connect the fixed push rod to fix the fixed push rod on the connecting push plate, and the slot hole is used to allow the slot paper push rod to pass through; thus, when the fixed push plate moves upward on the second lead screw, it can only push the fixed push rod to fix the stator; thus, when the copper wire push rod and the slot paper push rod push the copper wire and the slot paper into the stator, the stator position does not shift, thereby making the wire insertion smoother and more precise, and improving the production quality of the stator.

[0018] In one embodiment of the present invention, a guide block is fixed on the upper base plate, and a through hole coaxial with the circular hole is provided in the middle of the guide block for the passage of the copper wire push rod and the fixed push rod;

[0019] The guide block is provided with guide holes corresponding to the slot holes.

[0020] Through the above technical solution, the guide block is used to limit the pushing direction of the copper wire push rod, the slot paper push rod and the fixed push rod, so that the slot paper and copper wire can be smoothly embedded into the stator.

[0021] In one embodiment of the present invention, a fixing frame is fixed on the lower side of the upper base plate, one end of the second lead screw is connected to the fixing frame, and the third drive assembly is disposed on the fixing frame.

[0022] Through the above technical solution, the fixing frame is used to support the second lead screw and the second drive assembly.

[0023] In one embodiment of the present invention, a guide post is provided between the upper base plate and the lower base plate, and a guide sleeve that cooperates with the guide post is provided on the main plate and the fixed push plate.

[0024] Through the above technical solution, the guide post and guide sleeve cooperate to make the main board and the fixed push plate move more smoothly and steadily on the connecting screw.

[0025] In one embodiment of the present invention, the first drive component, the second drive component, and the third drive component each include a drive motor, a synchronous pulley, and a synchronous belt.

[0026] As described above, the winding drive device for a winding machine according to the present invention has the following beneficial effects:

[0027] 1. The first pushing component is used to simultaneously push the copper wire pusher and the slot paper pusher, thereby embedding the copper wire or copper wire end and the slot paper together into the stator, thereby reducing the resistance during wire embedding and improving the smoothness of wire embedding; the second pushing component set on the main board is used to adjust the height difference between the top of the copper wire pusher and the slot paper pusher. The mounting plate drives the slot paper pusher to move downward on the first lead screw, exposing the copper wire pusher to the outside of the slot paper pusher, so that the copper wire pusher can smoothly hook the copper wire and push the copper wire into the stator without interfering with the slot paper pusher;

[0028] 2. The third pushing component is used to fix the stator to be embedded. The fixed push plate moves up on the second lead screw and pushes the fixed push rod to be inserted into the stator, thus fixing the stator. As a result, when the copper wire push rod and the slot paper push rod push the copper wire and slot paper into the stator, the stator position does not shift, thereby making the embedding more fluid and precise and improving the production quality of the stator.

[0044] Brief description of the working process: After the first drive assembly 5 drives the main board 81 to push the slotted paper pusher 153 and the copper wire pusher 82 upward by a certain distance, the second drive assembly 6 drives the mounting plate 152 to move the slotted paper pusher 153 downward, exposing the copper wire pusher 82 outside the slotted paper pusher 153. Then, after the main board 81 drives the slotted paper pusher 153 and the copper wire pusher 82 to continue to move upward, the piston rod of the cylinder 111 is released, driving the copper wire pusher 82 to rotate, thereby hooking the copper wire end on the work station. When the main board 81 continues to move upward to the critical stator edge of the copper wire pusher 82, the third drive assembly 7 drives the fixed push plate 192. The main board 81 and the fixed push plate 192 move upward together, thereby causing the fixed pusher 193, the copper wire pusher 82 and the slotted paper pusher 153 to move upward together. Then, while the fixed pusher 193 fixes the stator, the copper wire pusher 82 and the slotted paper pusher 153 simultaneously push the copper wire and the slotted paper into the stator.

[0045] In summary, the third pushing component 19 in this invention is used to fix the stator to be wired. The fixed push plate 192 moves upward on the second lead screw 191, pushing the fixed push rod 193 to insert into the stator, thus fixing the stator. Therefore, when the copper wire push rod 82 and the slotted paper push rod 153 push the copper wire and slotted paper into the stator, the stator position does not shift, resulting in smoother and more precise wire insertion and improved stator production quality. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
