Description

Technical Field

[0001] The present invention relates to the technical field of transformer processing, and specifically to a braking winding machine for transformer coils. Background Art

[0002] The transformer workshop of power enterprises usually includes a winding group, an insulation group, an iron cutting group, an assembly group, and an experimental station, etc. The frequent replacement of transformers poses a great challenge to the winding work. The winding work is to wind copper wires into coils according to a specified form, and the coils are divided into high voltage and low voltage. The winding work process is that one person uses a winding machine to wind a low-voltage coil, and then another person uses another winding machine to wind a high-voltage coil on the low-voltage coil.

[0003] In existing transformers, the copper wire winding mechanism for copper wires generally uses fixed clamps at both ends of the copper wire, cooperating with a rotating clamp for loading the transformer iron core, so that the copper wire is wound around the middle of the transformer iron core. In the transformer coil winding machine with this structure, miswinding is likely to occur in the part of the fixed clamp for the copper wire, resulting in copper wire breakage. Summary of the Invention

[0004] The object of the present invention is to solve the above defects and provide a braking winding machine for transformer coils.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A braking winding machine for transformer coils includes a frame and a height adjustment mechanism, a height driving mechanism, and a copper wire winding mechanism provided on the frame. The frame is composed of brackets and a frame plate. The brackets are respectively fixedly connected to both sides of the frame plate. The frame plate is in a vertical structure and is parallel to the brackets. The height adjustment mechanism is provided on the brackets on both sides of the frame plate and is located on the front end face of the frame plate. The copper wire winding mechanism is fixedly connected to the bottom of the height adjustment mechanism. The copper wire winding mechanism can move up and down along the front end face of the frame plate through the height adjustment mechanism. The height driving mechanism is provided on the top of the frame plate. The bottom of the height driving mechanism is movably connected to the height adjustment mechanism. By pushing the height adjustment mechanism through the height driving mechanism, the height adjustment mechanism can move up and down along the brackets.

[0007] In the above description, as a further solution, the copper wire winding mechanism includes a guiding lead wire cylinder, a winding servo motor, and a winding clamp for clamping one end of the copper wire. The winding clamp is rotatably connected to the center of the bottom of the winding servo motor. The guiding lead wire cylinder is in a cylindrical hollow structure. The guiding lead wire cylinder is sleeved on the bottom of the winding servo motor, and the winding clamp is located below the guiding lead wire cylinder. By sleeving the guiding lead wire cylinder on the top of the winding servo motor, the winding clamp rotates one end of the copper wire along the center of the guiding lead wire cylinder, so that the copper wire can rotate and wind at the bottom of the guiding lead wire cylinder following the winding clamp.

[0008] In the above description, as a further solution, the bottom of the guiding lead cylinder is provided with an outwardly protruding guiding bracket. The guiding bracket is in an inverted "L" shape structure. A guiding hole is opened at the end of the guiding bracket. One side of the winding jig is a connecting and fixing part. An installation keyway is opened at the center of the connecting and fixing part. The bottom of the winding servo motor is a rotatable installation rotating shaft. Through the insertion between the installation rotating shaft and the installation keyway, the winding jig is rotatably connected to the winding servo motor. One end of the copper wire is passed through the guiding hole and fixedly connected to the winding jig at the same time. When the copper wire is wound around the transformer core, the copper wire can be guided by the guiding bracket.

[0009] In the above description, as a further solution, one side of the connecting and fixing part is provided with a lead bracket extending outward. The lead bracket is in an inverted "L" shape structure. The end of the lead bracket away from the connecting and fixing part is a winding chuck for clamping one end of the copper wire. The winding chuck is rotatably connected to the end of the lead bracket. By rotatably connecting the winding chuck inside the lead bracket, the copper wire rotates following the winding chuck, so that the copper wire and the winding chuck can rotate synchronously, preventing the middle part of the copper wire from being wound around the middle part of the lead bracket.

[0010] In the above description, as a further solution, a wiring component is provided inside the guiding lead cylinder. The wiring component includes a wiring servo motor and a telescopic mounting frame. The bottom of the telescopic mounting frame is fixedly connected to the top of the winding servo motor. The top of the telescopic mounting frame is movably connected to the wiring servo motor. The winding servo motor can move up and down inside the guiding lead cylinder through the telescopic mounting frame.

[0011] In the above description, as a further solution, the bottom of the wiring servo motor is a rotatable transmission lead screw. The transmission lead screw penetrates through the top of the telescopic mounting frame and is screwed to the top end surface of the telescopic mounting frame. Guide rods extending downward are provided at the four corners of the bottom of the wiring servo motor. One end of the guide rod penetrates through the top end surface of the telescopic mounting frame. The telescopic mounting frame can move below the wiring servo motor along the transmission lead screw. By screwing the transmission lead screw at the bottom of the winding servo motor to the telescopic mounting frame, the telescopic mounting frame drives the winding servo motor to move inside the guiding lead cylinder, so that when the winding chuck rotates and winds following the moving winding servo motor, the winding height can be adjusted at the same time, enabling the copper wire to be evenly wound on the side wall of the transformer.

[0012] In the above description, as a further solution, the height adjustment mechanism includes an adjustment guide rail and a fixed mounting plate. The adjustment guide rails are respectively fixedly connected to the front end surface of the bracket. The adjustment guide rails are in a vertical state on the front end surface of the bracket. Both ends of the fixed mounting plate are movably connected to the adjustment guide rails through slide bases. The copper wire winding mechanism is fixedly connected to the bottom of the fixed mounting plate.

[0013] In the above description, as a further solution, the bottom of the sliding table base is fixedly connected to the end of the fixed mounting plate, and there is a clearance fit between one side wall of the sliding table base and the sliding table base, so that the fixed mounting plate can slide up and down along the adjustment guide rail through the sliding table base.

[0014] In the above description, as a further solution, the height driving mechanism includes a telescopic cylinder and a push block. The telescopic cylinder is fixedly connected to the top of the frame plate. One end of the telescopic cylinder is a push rod, and the push block is fixedly connected to the end of the push rod. The push block can be moved to the top surface of the fixed mounting plate through the telescopic cylinder and abuts against the fixed mounting plate.

[0015] The beneficial effects produced by the present invention are as follows:

[0016] In the transformer coil braking winding machine of the present application, a guiding lead cylinder is sleeved on the top of the winding servo motor at the copper wire connection part, so that the winding fixture rotates one end of the copper wire along the center of the guiding lead cylinder, so that the copper wire can follow the winding fixture and rotate and wind at the bottom of the guiding lead cylinder. The structure makes the concentric circle structure between the fixed end of the copper wire, that is, the winding fixture, and the guiding end of the copper wire, that is, the guiding lead cylinder. When the copper wire is wound, only the fixed end of the copper wire, that is, the winding fixture, rotates and winds, and is located inside the guiding end of the copper wire, that is, the guiding lead cylinder, avoiding miswinding and copper wire breakage during winding, and improving the production yield of the transformer.
