Description

Technical Field

[0001] The utility model relates to the technical field of motor connecting wires, in particular to a wear-resistant connecting wire for a servo motor. Background Art

[0002] Although traditional servo motor cables can meet basic electrical transmission needs, in certain specific industrial application scenarios, such as machine tools, woodworking grinders, CNC equipment, and robots, the cables are often subject to frequent bending and stretching. During this bending and stretching process, the cables come into contact with and rub against the machine tools, woodworking grinders, CNC equipment, etc., causing friction damage to the insulation layer on the outer surface of the cables, shortening the service life of the cables.

[0003] As in the prior art, the patent with authorization announcement number CN218975171U discloses a wear-resistant servo motor cable, which is provided with a card block, a card slot, an anti-slip layer, a wear-resistant sleeve and a wear-resistant net. The wear-resistant sleeve is moved and wrapped around the cable. Several card blocks are pressed and inserted into several card slots to install a wear-resistant assembly consisting of a wear-resistant sleeve and a wear-resistant net on the surface of the motor cable. When the wear-resistant assembly is damaged, the user only needs to remove the several card blocks from the several card slots to remove it from the motor cable, and then reinstall a new wear-resistant assembly on the surface of the motor cable. The detachable wear-resistant assembly provided on the motor cable enhances the wear-resistant effect of the motor cable, making the motor cable less likely to be damaged by friction.

[0004] Although the private service motor cable has good wear resistance, it is necessary to replace the wear-resistant components on the cable in time when the wear-resistant components are excessively worn. When the servo motor is installed, the replacement of the wear-resistant components on the cable is limited by the equipment space setting, which is inconvenient to replace and affects work efficiency. In addition, if the wear-resistant components are not replaced in time, the internal insulation layer will be damaged, resulting in the risk of electric shock. Therefore, a wear-resistant connecting cable for a servo motor is designed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology and to propose a wear-resistant connecting wire for a servo motor.

[0006] The technical problem to be solved by the utility model is to provide a wear-resistant connecting wire for a servo motor, in which the wear-resistant components need to be frequently replaced, thus affecting the working efficiency.

[0007] The utility model provides a wear-resistant connecting wire for a servo motor, comprising a connecting wire body and an anti-friction component, wherein a plurality of anti-friction components are installed at equal distances on the outer surface of the connecting wire body;

[0008] The anti-friction component includes a ground contact ring, a spherical groove and a rolling ball. The ground contact ring is fixedly arranged on the outer surface of the connecting line body. A plurality of spherical grooves are opened in the center of the outer surface of the ground contact ring. Rolling balls are rolled in the spherical grooves.

[0009] Preferably, the diameter of the spherical groove is the same as that of the rolling ball.

[0010] Preferably, an opening is provided at one end of the spherical groove facing the outer surface of the ground contact ring, and the diameter of the opening is smaller than the diameter of the rolling ball, and the end of the rolling ball away from the spherical groove extends out of the opening.

[0011] Preferably, the number of the spherical grooves and the rolling balls is 12-16, and the spherical grooves and the rolling balls are evenly distributed in the center of the outer surface of the contact ring.

[0012] Preferably, the connecting wire body includes a core wire, an insulation layer, a wear-resistant layer and a wear-resistant mesh. There are multiple core wires, and the outer surfaces of the multiple core wires are wrapped with an insulation layer. The outer sides of the multiple core wires are wrapped with a wear-resistant layer, and the outer surface of the wear-resistant layer is fixedly provided with a wear-resistant mesh.

[0013] Preferably, the insulating layer is made of rubber material, the wear-resistant layer is made of asbestos fiber material, and the wear-resistant mesh is made of nylon material.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] 1. The utility model is provided with an anti-friction component, and multiple anti-friction components are arranged at equal distances outside the cable. When the connecting line body of the servo motor contacts the equipment during bending and stretching, the anti-friction component first contacts the equipment to prevent the connecting line body from contacting the equipment and preventing the connecting line body from being damaged. The ball on the anti-friction component extends out of the opening of the spherical groove. When the anti-friction component contacts the equipment, the ball will first contact the surface of the equipment, and the ball rolls on the equipment, changing the sliding friction into rolling friction, reducing the wear of the anti-friction component, and increasing the service life of the anti-friction component and the connecting line body.

[0016] 2. The utility model is provided with an insulating layer, a wear-resistant layer and a wear-resistant mesh. The insulating layer can isolate the power transmission on the core wire to prevent electric shock. The wear-resistant layer is made of asbestos fiber. Asbestos fiber not only has good wear resistance, but also has good fire resistance, heat insulation and electrical insulation. Due to its compact and soft fiber structure, asbestos can withstand greater stress when bent and is not easy to break, thereby increasing the service life of the connecting wire body. The wear-resistant mesh is made of nylon material, which has good wear resistance and tear resistance, further increasing the service life of the connecting wire body.

[0024] Example:

[0025] like Figure 1-Figure 4 As shown, an embodiment of the present invention provides a wear-resistant connecting wire for a servo motor, comprising a connecting wire body 1 and an anti-friction component, wherein a plurality of anti-friction components are installed at equal distances on the outer surface of the connecting wire body 1;

[0026] The anti-friction component includes a grounding ring 2, a spherical groove 201 and a rolling ball 202. The grounding ring 2 is fixedly arranged on the outer surface of the connecting line body 1. A plurality of spherical grooves 201 are opened in the center of the outer surface of the grounding ring 2, and a rolling ball 202 is rolled in the spherical groove 201.

[0027] In this embodiment, the diameter of the spherical groove 201 is the same as that of the ball 202 .

[0028] In this embodiment, an opening is provided at one end of the spherical groove 201 facing the outer surface of the contact ring 2, and the diameter of the opening is smaller than the diameter of the ball 202. The end of the ball 202 away from the spherical groove 201 extends out of the opening, making it convenient for the ball 202 to contact the friction area.

[0029] In this embodiment, 12 to 16 spherical grooves 201 and 16 rolling balls 202 are provided, and the spherical grooves 201 and the rolling balls 202 are evenly distributed in the center of the outer surface of the contact ring 2 to ensure the uniform distribution of the rolling balls 202.

[0030] By providing an anti-friction component, multiple anti-friction components are provided at equal distances outside the cable. When the connecting cable body 1 of the servo motor contacts the device during bending and stretching, the anti-friction component first contacts the device to prevent the connecting cable body 1 from contacting the device and preventing the connecting cable body 1 from being damaged. The ball 202 on the anti-friction component extends out of the opening of the spherical groove 201. When the anti-friction component contacts the device, the ball 202 will first contact the surface of the device. The ball 202 rolls on the device, changing the sliding friction into rolling friction, reducing the wear of the anti-friction component, and increasing the service life of the anti-friction component and the connecting cable body 1.

[0031] In this embodiment, the connecting wire body 1 includes a core wire 101, an insulating layer 102, a wear-resistant layer 103 and a wear-resistant mesh 104. There are multiple core wires 101, and the outer surfaces of the multiple core wires 101 are wrapped with the insulating layer 102. The outer sides of the multiple core wires 101 are wrapped with the wear-resistant layer 103, and the outer surface of the wear-resistant layer 103 is fixedly provided with a wear-resistant mesh 104.

[0032] In this embodiment, the insulating layer 102 is made of rubber material and has good insulation properties. The wear-resistant layer 103 is made of asbestos fiber material. Asbestos is a natural mineral fiber with good fire resistance, heat insulation and electrical insulation. Due to its tight and soft fiber structure, asbestos can withstand greater stress when bent and is not easy to break. In addition, asbestos fiber has good wear resistance and can increase the wear resistance of the connecting wire body 1. The wear-resistant mesh 104 is made of nylon material. The strength of nylon is several times that of natural fibers and is the strongest among synthetic fibers. Therefore, it has good wear resistance, tear resistance and fatigue resistance.

[0033] By providing an insulating layer 102, a wear-resistant layer 103 and a wear-resistant mesh 104, the insulating layer 102 can isolate the power transmission on the core wire to prevent electric shock. The wear-resistant layer 103 is made of asbestos fiber. Asbestos fiber not only has good wear resistance, but also has good fire resistance, heat insulation and electrical insulation. Due to its compact and soft fiber structure, asbestos can withstand greater stress when bent and is not easy to break, thereby increasing the service life of the connecting wire body 1. The wear-resistant mesh 104 is made of nylon material, which has good wear resistance and tear resistance, further increasing the service life of the connecting wire body 1.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
