Description

Technical Field

[0001] This utility model belongs to the field of robotic welding technology, specifically relating to a follow-up robot welding torch cable support device. Background Technology

[0002] When a robot is welding, the welding cable is an important component and is installed on the robot arm. In order to ensure that the welding cable has a good working posture, some robot arms are equipped with brackets to support the welding cable.

[0003] The commonly used cable brackets on the market all install the welding gun cable on one end of the bracket in a completely secure manner. Although this method solves the problem of welding cable support, it can only ensure that the robot welding gun cable is in a relatively smooth state under certain specific postures. When the robot performs different postures, especially when the robot posture is more difficult, the welding gun cable is affected, and the overall smoothness is greatly reduced, which in turn affects the stability of the welding wire feeding. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a follow-up robot welding gun cable support device. The bushing follows the welding gun cable to rotate and adjust the angle, so that the welding gun cable is always in a smooth state and the stability of wire feeding is guaranteed.

[0005] This utility model provides the following technical solution:

[0006] A follow-up robot welding torch cable support device is provided. The cable support device is installed on the robot and includes a bushing, a support member, and a bracket. The support member is located on the top of the bracket. The bushing is movably connected inside the support member and is sleeved on the welding torch cable for adjusting the angle following the welding torch cable.

[0007] As an optional technical solution of this utility model, the bottom of the bracket is fixedly installed on the robot's arm.

[0008] As an optional technical solution of this utility model, the bushing includes an outer ring and an inner ring; the outer ring is fixedly installed inside the support member, and the inner ring is movably connected to the outer ring.

[0009] As an optional technical solution of this utility model, the mating surfaces of the outer ring and the inner ring are arc surfaces.

[0010] As an optional technical solution of this utility model, the inner ring is fixedly sleeved on the welding gun cable.

[0011] As an optional technical solution of this utility model, one end of the welding gun cable is fixedly connected to the welding gun of the robot, and the other end is fixedly connected to the inner ring.

[0012] As an optional technical solution of this utility model, the support member is fixedly installed on the top of the bracket.

[0013] As an optional technical solution of this utility model, the support member adopts a support flange.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The follow-up robot welding torch cable bracket device provided by this utility model is a support component that is movably connected by a bushing. The bushing is fitted with the welding torch cable and rotates and adjusts its angle in a following manner with the welding torch cable, so that the welding torch cable is always in a smooth state, ensuring the stability of wire feeding and improving welding quality.

[0020] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0021] Example 1

[0022] This embodiment provides a follow-up robot welding torch cable support device, such as... Figure 1 As shown, the cable bracket device 2 is mounted on the robot 1.

[0023] like Figure 2As shown, the cable support device 2 includes a bushing 4, a support member 5, and a bracket 6. The support member 5 is located on the top of the bracket 6; the bushing 4 is movably connected inside the support member 5 and is sleeved on the welding torch cable 3 to adjust its angle according to the welding torch cable 3, so that the welding torch cable is always in a smooth state and the stability of wire feeding is guaranteed.

[0024] Example 2

[0025] This embodiment provides one implementation method for each structure based on embodiment 1.

[0026] like Figure 1 As shown, the bottom of the bracket 6 is fixedly installed on the arm of the robot 1.

[0027] like Figure 2 As shown, the support member 5 is fixedly installed on the top of the bracket 6 by fixing bolts. In this embodiment, the support member 5 is a support flange.

[0028] like Figure 3 As shown, the bushing 4 includes an outer ring 4.1 and an inner ring 4.2; the outer ring 4.1 is fixedly installed inside the support member 5, and the inner ring 4.2 is movably connected to the outer ring 4.1. In this embodiment, the bushing 4 is a spherical bearing.

[0029] Furthermore, the mating surfaces of the outer ring 4.1 and the inner ring 4.2 are arc surfaces, allowing for free rotation and tilting at a certain angle between the inner and outer rings through various methods such as sliding or rolling. The inner ring 4.2 tilts along the axis, with a tilt range of 360°, not limited to a single direction.

[0030] Furthermore, the inner ring 4.2 is fixedly sleeved on the welding torch cable 3. One end of the welding torch cable 3 is fixedly connected to the welding torch of the robot 1, and the other end is fixedly connected to the inner ring 4.2.

[0031] When robot 1 moves, the welding torch fixed to the front end of the main body also moves and rotates, which in turn drives the welding torch cable 3 installed at the rear end to move. Due to the action of the bushing 4, the welding torch cable 3 automatically rotates and changes its tilt angle, thereby making the posture of the welding torch cable 3 more relaxed and smooth, improving the stability of the welding wire feeding, and thus improving the welding effect.

[0032] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.
