Description

Technical Field

[0001] The utility model relates to the technical field of transformer coil production equipment, in particular to a winding device for transformer coil production. Background Art

[0002] When producing transformer coils, it is usually necessary to use coil winding equipment to wind metal wires or metal foils onto a winding die. Traditional equipment requires the winding die to be installed on the winding shaft of the winding equipment during winding. In order to facilitate the installation of the winding die on the winding shaft, the winding die and the winding shaft are generally fitted with a gap. This connection method with a gap requires the winding shaft to drive the winding die to rotate at a high degree during winding. Under the weight of the winding die and the coil, there will be a large relative friction between the winding die and the winding shaft, resulting in more wear on the winding die and the winding shaft. At the same time, due to the gap, radial relative displacement occurs between the winding die and the winding shaft during the winding process, which also causes uneven coil winding. Summary of the invention

[0003] 1. Technical issues to be solved

[0004] The technical problem to be solved by the utility model is that the winding die and the winding shaft are both clearance-matched. When winding, because the winding shaft needs to drive the winding die to rotate at a high degree, a large relative friction will be generated between the winding die and the winding shaft under the weight of the winding die and the coil, resulting in more wear on the winding die and the winding shaft. At the same time, due to the gap, radial relative displacement occurs between the winding die and the winding shaft during the winding process, which will also lead to the problem of uneven coil winding.

[0030] It comprises a base 1, a transverse moving device 2 and a clamping device 3. Two clamping devices 3 are provided, one of which is arranged on the transverse moving device 2 and the other is fixedly arranged on the base 1. The transverse moving device 2 is arranged on the base 1. The transverse moving device 2 drives one of the clamping devices 3 to move, and the distance between the two clamping devices 3 can be adjusted, which is convenient for the installation of the winding die and the disassembly of the wound workpiece.

[0031] The clamping device 3 includes an equipment box 301, a winding reduction motor 302 and a clamping jaw assembly 303. The winding reduction motor 302 is arranged on the equipment box 301, and the output shaft of the winding reduction motor 302 is connected to the clamping jaw assembly 303 to provide rotational power for it. The clamping jaw assembly 303 includes a clamp seat 3031, a group of adjustment components 3032 and four claws 3033. The clamp seat 3031 is connected to the output shaft of the winding reduction motor 302, and a groove is provided on the clamp seat 3031 for facilitating the installation of the adjustment component 3032. 3034, two adjustment components 3032 are arranged on the clamp seat 3031 in a cross-shaped and vertically staggered arrangement, the adjustment component 3032 includes an adjustment screw 3032a, two left-right rotating nuts 3032b and a slide 3032c arranged on the left-right rotating nuts 3032b, four claws 3033 are respectively fixed on the slide 3032c, and the adjustment screw 3032a is connected to the clamp seat 3031 through a bearing, and a part of both ends of the screw extends to the outside of the clamp seat 3031.

[0032] Specifically, the transverse movement device 2 includes a group of linear guide pairs 2a, transmission screw pairs 2b and transverse movement motors 2c fixedly arranged on the base 1. The transmission screw pairs 2b and the transverse movement motors 2c are both fixedly arranged on the base 1, and the screw on the transmission screw pair 2b is connected to the rotating shaft of the transverse movement motor 2c through a coupling. The slider on the linear guide pair 2a and the screw nut seat on the transmission screw pair 2b are both fixedly connected to the bottom end surface of the equipment box 301 in the clamping device 3 arranged on the transverse movement device 2.

[0033] Specifically, a pad 3036 is also provided on the claw 3033 .

[0034] In this embodiment, the backing plate 3036 with appropriate hardness is used to reduce the possibility of damaging the winding die when clamping it.

[0035] Specifically, the clamp seat 3031 has a cross-shaped structure, and two grooves 3034 are provided and arranged in a cross shape. A slide 3035 that cooperates with the slide seat 3032c is provided on the inner side surface of the groove 3034. The slide 3035 and the clamp seat 3031 are an integrally formed structure, and a slide groove 3032d that cooperates with the slide 3035 is provided on the slide seat 3032c.

The accordion cover 5 and the dustproof plate 4 are both used for dust prevention, and the accordion cover 5 mainly prevents dust from falling onto the linear guide pair 2a.

[0039] Working principle: when installing the winding die, the worker uses the lifting tool to transfer the winding die to the position of the clamping device 3, and then initially places the two ends of the winding die on the two clamping components 303, and then adjusts the clamping claw component 303 set at one end of the transverse device 2 to clamp the winding die. Specifically, the worker uses a wrench or other tool to rotate the adjusting screw 3032a, and then the left-right nut 3032b rotates to drive the slide 3032c to move, and then drives the two claws 3033 on the same adjusting screw 3032 to make reverse linear motion, so as to achieve the purpose of clamping the winding die. Of course, the adjustment methods of the two adjusting screws 3032a here are the same, and then the winding die is moved to the clamping workspace of another clamping claw component 303 through the transverse device 2, and the two adjusting screws 3032a use the same adjustment method as above to clamp the other end of the winding die, and finally complete the clamping work of the winding die. The winding reduction motors 302 on the two clamping devices 3 work simultaneously during winding, and jointly provide rotational power for the winding work.
