Description

Technical field:

[0001] The utility model relates to a tool for winding a transformer coil, in particular to a tool for clamping the winding coil and capable of restraining a transposed conductor, which is used in the transformer coil winding process. Background technology:

[0002] During the transformer coil winding process, the raw material spool is first placed on the pay-off stand, and then the wire passes through the coil winding machine equipment, and then the coil is wound manually.

[0003] Currently, large transformer coils are mostly wound using both vertical and horizontal methods. Horizontal winding offers significant advantages, including mechanical stability, effective reduction of wire stretching and insulation damage during the winding process, improved production efficiency, and ease of maintenance. Therefore, horizontally wound transformer coils are irreplaceable.

[0004] Although horizontal winding has many advantages, there are still some shortcomings in the current coil horizontal winding process. For example, it is found that large-sized transposed wires are very easy to twist, deform or tilt during winding. Operators need to manually correct and support the wires to make them square and regular. This method is time-consuming and labor-intensive, seriously affecting the coil forming quality. In addition, some existing winding equipment does not have enough restraint force for large-sized wires. Summary of the invention:

[0005] The technical problem to be solved by the utility model is to provide a tool for clamping a coil of a restrained transposed conductor, which can fix and restrain large-sized conductors and is not easily twisted or tilted during winding.

[0006] The purpose of this utility model is achieved in this way:

[0007] The two roller brackets are fixed on the top of the base and have the same structure. The rear end surfaces of the two support plates are provided with axial rear slide grooves. The front end surfaces of the two roller brackets are fixed with sliders. The two roller brackets are respectively installed in cooperation with the rear slide grooves of the two support plates through the sliders. The roller brackets can slide up and down in the rear slide grooves of the support plates. Nylon rollers are provided between the two roller brackets, that is, the roller shafts at the left and right ends of the nylon rollers are respectively connected to the two roller brackets. Square nuts are provided in the rear slide grooves of the two support plates. There are screw holes on the two roller brackets. Hexagon socket screws are used to pass through the screw holes of the roller brackets and connect with the square nuts in the rear slide grooves of the support plates. The outer end of the hexagon socket screw is exposed from the rear end surface of the roller bracket. When the position of the roller bracket is adjusted, tightening the hexagon socket screw can achieve the positioning of the roller bracket.

[0008] The front ends of the two support plates are each provided with an axial front slot, each housing an upper and lower transverse nylon roller bracket. A slider is secured to the rear end of each transverse nylon roller bracket, and each transverse nylon roller bracket is mounted to the front slot of the support plate via the slider. The front slots of the two support plates are each provided with an upper and lower square nut. Each transverse nylon roller bracket has a screw hole, which is connected to the corresponding square nut in the front slot of the support plate using a hexagon socket screw through the screw hole in the transverse nylon roller bracket. The outer end of the hexagon socket screw protrudes from the front end of the transverse nylon roller bracket. Once the transverse nylon roller bracket is positioned, tightening the hexagon socket screw achieves positioning. The left and right shafts of the lower transverse nylon roller are respectively mounted on the two lower transverse nylon roller brackets. The upper surfaces of the two upper transverse nylon roller brackets are each provided with a groove, and the left and right shafts of the upper transverse nylon roller are respectively placed in the grooves on the upper surfaces of the two upper transverse roller brackets.

[0009] Each of the square nuts can slide up and down in its own slide groove.

[0010] It also includes an upper limit plate and a lower limit plate, the upper limit plate is located directly above the lower limit plate, and the upper limit plate and the lower limit plate are located between the two support plates, and the left and right ends of the upper limit plate and the lower limit plate are respectively fixed to the two support plates; the upper limit plate and the lower limit plate are provided with corresponding long holes, and a plurality of vertical nylon rollers are provided between the upper limit plate and the lower limit plate, and the shafts at the upper and lower ends of each vertical nylon roller are respectively located in the long holes of the upper limit plate and the lower limit plate, and the shafts of the vertical nylon rollers exposed from the upper limit plate and the lower limit plate are threaded, and the vertical nylon rollers can be limited by screwing nuts and spring washers onto the threads at both ends of the shaft and fastening them to the upper and lower limit plates.

[0011] The utility model has the advantages that during operation, the distance between the vertical nylon rollers is adjusted according to the thickness of the transposed conductor, the distance between the upper and lower horizontal rollers is adjusted according to the height of the transposed conductor, and the position of the nylon roller is adjusted according to the height of the outlet wire between the spool and the winding die.

[0012] When large-sized wires pass through this clamping tool, the vertical nylon rollers constrain the transposed wires to the left and right to keep them upright, and the horizontal nylon rollers constrain the transposed wires to the top and bottom to keep the wires stable, ensuring that the transposed wires do not bulge, twist, or fall over when they are wound.
