[0027] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments:

[0028] Embodiment 1

[0029] Since the length and diameter of the winding will affect the resistance value of the winding resistance, different diameters of windings are required to generate winding resistors with different resistance values. During the winding process, a clamping assembly is generally required to clamp the winding to control the tension of the winding to generate the required winding resistance. Currently, there is no device that can select and install a suitable clamping assembly for windings of different diameters.

[0030] Therefore, the present utility model provides a resistor winding device for facilitating winding replacement, which adopts a clamping assembly that is easy to disassemble and assemble, so that it can replace a more suitable clamping part 5 according to the different diameters of the windings, ensuring the clamping effect of the clamping assembly on the winding and avoiding affecting the tension of the winding.

[0031] Specifically, the resistor winding device for facilitating winding replacement includes a workbench. A wire feeding assembly, a winding assembly, and a clamping assembly located between the wire feeding assembly and the winding assembly are arranged on the workbench. The winding passes through the wire feeding assembly, the clamping assembly, and the winding assembly in sequence. The clamping assembly includes a base 2. A sliding assembly 3 is connected below the base 2. A clamping part 5 is arranged above the base 2 in a detachable and installable manner. A circular hole 51 for the winding to pass through is provided on the side surface of the clamping part 5, and the winding is clamped through the circular hole 51.

[0032] Preferably, the base 2 is of a groove structure. An opening 21 connected to the inner wall of the base 2 is vertically arranged at the top of the base 2. An embedding part 6 adapted to the opening 21 is arranged below the clamping part 5. A chute extending in the horizontal direction is further arranged on the inner wall of the base 2, and the chute is communicated with the opening 21. When the embedding part 6 moves vertically into the opening 21 and then moves horizontally into the chute, the clamping part 5 is embedded in the base 2.

[0033] Preferably, the sliding component 3 includes a slider 31 sleeved on a threaded rod 32. The threaded rod 32 is horizontally located inside the workbench, and one end of the threaded rod 32 is connected to a driving motor. The top end of the slider 31 is fixedly connected to the base 2 to drive the base 2 to move along the extension direction of the threaded rod 32.

[0034] Preferably, a fixing part 7 is arranged above the clamping part 5, and a fixing component is arranged above the fixing part 7. The fixing component includes a sleeve rod 8 arranged parallel to the threaded rod 32, and a through hole parallel to the threaded rod 32 is formed in the sleeve rod 8. When the clamping part 5 is fixedly embedded in the base 2, the inner wall of the through hole is connected to the fixing part 7.

[0035] Preferably, support rods 9 are symmetrically arranged at both ends of the sleeve rod 8, and the support rods 9 are fixedly arranged on the workbench. Moreover, grooves with openings 21 facing the support rods 9 are arranged on the support rods 9, so that the support rods 9 are movably connected in the grooves. The grooves extend vertically, enabling the staff to push the support rods 9 up or down, facilitating the fixing effect of the sleeve rod 8 on the fixing part 7.

[0036] In this embodiment, to facilitate the operation of the staff, the disassembly and assembly method is rotary clamping. A wire paying-off roller 1 and a wire winding roller 4 are fixedly arranged on the workbench, and a threaded rod 32 is arranged inside the workbench. The wire paying-off roller 1 and the wire winding roller 4 are both arranged parallel to the threaded rod 32. A base 2 is connected to the threaded rod 32 through a slider 31. The base 2 is of a groove structure and its cross-sectional shape in the horizontal direction is circular, as Figure 1 shown. Moreover, two openings 21 are symmetrically arranged at the top of the base 2, and the two openings 21 are symmetrically arranged with respect to the threaded rod 32. The clamping part 5 is a cylinder, and the diameter of the cylinder is the same as the diameter of the circle. Embedding parts 6 extending outward in the circumferential direction are symmetrically arranged at the bottom of the cylinder. The embedding parts 6 can be embedded in the openings 21, enabling the clamping part 5 to be embedded in the base 2.

[0037] Specifically, a fixing part 7 extending in the extending direction of the embedding part 6 is arranged at the top of the cylinder. A round hole 51 is formed in the side surface of the cylinder, and the extending direction of the round hole 51 is perpendicular to the extending direction of the embedding part 6, as Figure 2 shown. Then, when the fixing part 7 is fixed in the sleeve rod 8, the extending direction of the round hole 51 is perpendicular to the central axes of the wire paying-off roller 1 and the wire winding roller 4 respectively, enabling the wire wound on the wire paying-off roller 1 to vertically pass through the round hole 51 and be connected to the wire winding roller 4 for winding, facilitating the control of the winding tension and avoiding the winding from being too loose or inclined.

[0038] When the staff wants to install the clamping part 5, first, the cylindrical embedding part 6 needs to be aligned with the opening 21, and then the cylinder is pushed downward into the base 2. At this time, the fixing part 7 is not arranged parallel to the sleeve rod 8, as Figure 3 shown. Then, for the parallel position of the sleeve rod 8, the cylinder is rotated so that the fixing part 7 rotates to be arranged parallel to the sleeve rod 8. At this time, the embedding part 6 will slide in the chute and slide to be arranged parallel to the sleeve rod 8, as Figure 4 shown, so that the embedding part 6 is embedded in the chute, and the clamping part 5 can be limited in the vertical direction to prevent the clamping part 5 from moving in the vertical direction. Then, the sleeve rod 8 is moved downward, and the sleeve rod 8 is clamped with the fixing part 7 through the through hole on the sleeve rod 8, so that the sleeve rod 8 is located on the clamping part 5, and the clamping part 5 can be limited in the horizontal direction to prevent the clamping part 5 from moving in the horizontal direction.

[0039] Moreover, the through hole in the sleeve rod 8 is parallel to the threaded rod 32, and the length of the through hole is greater than or equal to the length of the threaded rod 32. When the driving motor drives the threaded rod 32 to rotate, the slider 31 can be driven to move left and right along the extension direction of the threaded rod 32. At the same time, the slider 31 drives the clamping part 5 to move left and right along the extension direction of the threaded rod 32 through the base 2, and the through hole in the sleeve rod 8 can guide the movement of the clamping part 5 to prevent the clamping part 5 from shaking during the left and right movement, thereby avoiding the angular deviation of the winding during the winding process.

[0040] Preferably, a bottom plate 22 is arranged on the bottom surface of the base 2. When the clamping part 5 is embedded in the base 2, the lower surface of the clamping part 5 is connected to the bottom plate 22. A spring is vertically arranged below the bottom plate 22 for shock absorption, as Figure 5 shown.

[0041] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention. However, the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
