[0002] Bare copper flat wire is a conductor made of oxygen-free copper rods extruded or drawn by dies of certain specifications. Electrical copper flat wire can be used as a finished product or an intermediate product. It is widely used in the windings of motors, transformers, reactors and other similar electrical equipment. In the production process of bare copper flat wire, it is necessary to use a clamp to limit it and facilitate the winding.

[0003] The existing method uses fixed rollers to guide and control the wire tension. However, in actual operation, most of them are large-scale operating equipment in production workshops, which are relatively bulky and inconvenient to carry, and have poor effect on the collection of bare copper flat wires of different sizes. Summary of the invention

[0006] It is further characterized in that the facing sides of the clamping block are provided with limiting grooves;

[0007] A positioning groove is provided on the top of the housing, and two moving blocks connected to the second double-headed screw are arranged in the positioning groove. A scale line is marked above the positioning groove. An upper gear is installed at the right end of the second double-headed screw, and a lower gear meshing with the upper gear is installed on the second double-headed screw;

[0008] A vertical slot is provided on the left side of the housing, a third screw rod arranged vertically is installed in the vertical slot, the bracket is connected to the third screw rod, and the top of the third screw rod passes through the housing and is installed with a second knob;

[0009] The bracket includes a lifting frame and a rotating frame, one end of the lifting frame is connected to the third screw rod, and the other end is connected to the rotating frame through a pin shaft, the pulleys are respectively installed on the lifting frame and the rotating frame, and the cylinder body of the adjusting cylinder is hingedly installed on the lifting frame, and the piston rod end of the adjusting cylinder is hingedly connected to the rotating frame.

[0010] After adopting the utility model, by passing the bare copper flat wire through two clamping blocks and turning the first knob, the knob drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the rotating shaft to rotate, the rotating shaft drives the first bevel gear to rotate, and the first bidirectional screw rotates with the cooperation of the second bevel gear, and finally the clamping block moves to limit the bare copper flat wire, so that it is convenient to position the bare copper flat wires of different sizes and to facilitate the winding; its further feature is that the bracket is composed of a lifting frame and a rotating frame, which can realize the lifting and lowering of the pulley and the change of the angle between the two pulleys, thereby achieving the adjustment of the incoming wire angle.

[0015] See Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a clamp for taking up bare copper flat wires comprises a housing 1, a wire passing area 2 is provided in the middle of the housing 1, two symmetrically arranged clamping blocks 3 are arranged in the wire passing area 2, the lower part of the clamping block 3 is embedded in the guide groove 4, and the upper part is connected to the first double-headed screw 6 through the slider 5, and the first bevel gear 7 is installed on the right side of the first double-headed screw 6, a driving cavity is provided inside the right side of the housing 1, a worm gear mechanism is installed in the driving cavity, a worm gear 8 is connected to the rotating shaft 9, and a second bevel gear 10 meshing with the first bevel gear 7 is provided on the rotating shaft 9, and the right side of the worm 25 passes through the side wall of the driving cavity and extends out of the housing and is installed with a first knob 11, by rotating the first knob 11, the worm gear and the bevel gear mesh, and the double-headed screw rotates, and finally the synchronous movement of the two clamping blocks 3 is realized, and the positioning of bare copper flat wires of different sizes is realized by adjusting the spacing. Limiting grooves are provided on the opposite sides of the clamping blocks 3.

[0016] A positioning groove 12 is provided on the top of the shell 1, and two moving blocks 14 connected to the second double-headed screw 13 are arranged in the positioning groove 12. The thickness of the moving block 14 is consistent with the height of the positioning groove 12, and scale lines are marked above the positioning groove 12. An upper gear 15 is installed on the right end of the second double-headed screw 13, and a lower gear 16 meshing with the upper gear 15 is installed on the second double-headed screw 13. When the first double-headed screw 5 rotates, the second double-headed screw 13 rotates with the cooperation of the upper gear 15 and the lower gear 16, and the moving block 14 moves and cooperates with the scale lines, so that the spacing of the clamping block 3 can be quickly and intuitively understood to adapt to bare copper flat wires of different sizes.

[0017] A vertical slot 17 is provided on the left side of the shell 1, and a vertically arranged third screw 18 is installed in the vertical slot 17. The bracket is connected to the third screw 18, and the thickness of the bracket 18 is consistent with the width of the vertical slot 17. The top of the third screw 18 passes through the shell 1 and is installed with a second knob 19; the bracket includes a lifting frame 20 and a rotating frame 21, one end of the lifting frame 20 is connected to the third screw 18, and the other end is connected to the rotating frame 21 through a pin 22. Pulleys 23 are installed on the lifting frame 20 and the rotating frame 21 respectively. The cylinder body of the adjusting cylinder 24 is hingedly installed on the lifting frame 20, and the piston rod end of the adjusting cylinder 24 is hinged to the rotating frame 21. By extending the piston rod of the adjusting cylinder 24, the swing of the rotating frame 21 can be achieved. The incoming line direction is from bottom to top, so the rotating frame 21 rotates downward. The position shown in the figure is the highest point position, and at this time there is still a small angle between the rotating frame 21 and the lifting frame 20, ensuring that the rotating frame 21 can rotate downward to complete the adjustment of the incoming line angle.
