Technical Field

[0001] The utility model relates to the technical field of power device processing, in particular to a wire-paying auxiliary wheel for a power device aluminum wire machine. Background Art

[0002] Power devices mainly refer to devices used to regulate current and voltage and directly control power conversion. The aluminum wire machine of power devices unwinds the aluminum wire and cooperates with auxiliary wire-unwinding equipment to improve the stability of the aluminum wire during transportation. At the same time, the existing aluminum wire auxiliary wire-unwinding equipment usually uses a rubber wheel body to contact the aluminum wire to reduce damage caused by friction of the aluminum wire.

[0003] The utility model with publication number CN203593475U discloses a pay-off wheel device, in which a cover groove is provided on the inner end face of the end cover, the end cover is coaxially arranged with the pay-off shaft, the end cover is sleeved on the small baffle from the outer side of the small baffle through the cover groove, and covers the side of the small baffle. The wire-passing part is smooth and wear-resistant, which reduces the friction resistance of the wire during pay-off and realizes reliable and stable pay-off.

[0004] However, the above-disclosed pay-off wheel device still has the following problems during actual use: although the end of the pay-off shaft is covered by a baffle, this type of mechanism is only suitable for winding and releasing wound cables, and when the metal cable passes through this pay-off wheel, the contact surface is in direct contact with the metal wire, which will cause wear to the metal wire and cause the metal wire to bend, and the contact surface of the flexible material will be cut by the metal wire, thereby affecting the service life and increasing the number of replacements.

[0005] Therefore, we propose a wire-paying auxiliary wheel for a power device aluminum wire machine to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of the utility model is to provide a wire-paying auxiliary wheel for a power device aluminum wire machine, in order to solve the problem that the existing method covers the end of the wire-paying shaft with a baffle, but such a mechanism is only suitable for winding and releasing the wound cable. When the metal cable passes through the wire-paying wheel, the contact surface is in direct contact with the metal wire, which will cause wear to the metal wire and cause the metal wire to bend. The contact surface of the flexible material will be cut by the metal wire, thereby affecting the service life and increasing the number of replacement times.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a power device aluminum wire machine pay-off auxiliary wheel, comprising a positioning shaft and extended mounting sections fixedly mounted on the left and right ends of the positioning shaft; and further comprising:

[0008] The positioning shaft is provided with a positioning rotating part on both the left and right sides, and the positioning rotating part includes a positioning liner, and the positioning liner is fixedly installed on the left and right outer walls of the positioning shaft in a group of two;

[0009] An aluminum wire contact portion is disposed on the exterior of the positioning shaft, and the aluminum wire contact portion includes a positioning sleeve.

[0010] Preferably, the positioning shaft rod and the extended installation sections at the left and right ends are arranged in a concentric structure, and the positioning shaft rod is detachably installed through the extended installation sections.

[0011] Preferably, the positioning rotating portion includes a rotating bearing, and the rotating bearing is rotatably arranged on the left and right sides of the outer wall of the positioning shaft, and the rotating bearing contacts the inner wall of the positioning sleeve included in the aluminum wire contact portion.

[0012] Preferably, the positioning liner included in the positioning rotating part is arranged outside the left and right rotating bearings, and the positioning liner is used to ensure the stability of the rotating bearing during operation.

[0013] Preferably, the outer diameter of the positioning liner included in the positioning rotating part is smaller than the outer diameter of the rotary bearing, and the positioning sleeve included in the aluminum wire contact part is ensured to rotate outside the positioning shaft by the positioning rotating part.

[0014] Preferably, the aluminum wire contact portion includes an anti-slip ring, and the anti-slip ring is fixedly installed on the outer end of the positioning sleeve, and a rubber bushing is fixedly provided on the outer wall of the positioning sleeve.

[0015] Preferably, the aluminum wire contact portion includes a polyurethane bushing, and the polyurethane bushing is fixedly arranged on the outer wall of the rubber bushing, and the positioning sleeve, the rubber bushing and the polyurethane bushing are distributed in a concentric structure.

[0016] Preferably, the outer diameter of the polyurethane bushing included in the aluminum wire contact portion is smaller than the outer diameter of the anti-slip ring, and the anti-slip ring prevents the aluminum wire from falling off during the retraction process, and the polyurethane bushing directly contacts the retracted aluminum wire.

[0017] Preferably, the polyurethane bushing contained in the aluminum wire contact part is more oil-resistant, wear-resistant, low-temperature-resistant and aging-resistant than the rubber bushing. At the same time, the polyurethane bushing has high hardness and elasticity, which can reduce wear during use and control the number of replacements during maintenance to reduce costs.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the auxiliary wheel for the pay-off of the power device aluminum wire machine is installed through the positioning rotating part and the positioning sleeve outside the positioning shaft, and the positioning liner is arranged outside the rotating bearing to improve the stability during the rotation process. At the same time, the polyurethane bushing outside the rubber bushing contacts the aluminum wire. Through its better oil resistance, wear resistance, low temperature resistance and aging resistance, it can reduce wear during use, control the number of replacements during maintenance and reduce costs. The specific contents are as follows:

[0019] 1. The positioning shaft is positioned by the extended mounting section at the outer end to prevent the positioning shaft from shifting during operation. The left and right outer walls of the positioning shaft are installed for the rotary bearing, and the positioning linings are distributed on the left and right sides of the rotary bearing to prevent the rotary bearing from falling off during operation.

[0020] The inner wall of the positioning sleeve contacts the rotary bearings distributed on the left and right sides, so that the rotary bearings are interposed between the positioning shaft and the positioning sleeve as rotating components, ensuring that the positioning sleeve can rotate during the subsequent pay-off process.

[0021] 2. A polyurethane bushing is set on the outside of the rubber bushing, so that the polyurethane bushing replaces the rubber bushing and contacts the aluminum wire during operation. At the same time, the rubber bushing and the polyurethane bushing are positioned by anti-slip rings set at the left and right ends of the positioning sleeve. The anti-slip rings with an outer diameter larger than the polyurethane bushing can prevent the aluminum wire from falling off during the pay-off process.

[0022] At the same time, polyurethane bushings are harder than rubber bushings, and are more oil-resistant, wear-resistant, low-temperature-resistant, and aging-resistant, so that they can reduce wear during use and control the number of replacements during maintenance to reduce costs.
