Description

Technical Field

[0001] The utility model relates to the field of metal processing, in particular to an anti-static tower foot welding robot fixing device. Background Art

[0002] As an important load-bearing component of the iron tower, the tower foot has high requirements for welding processing quality and stability. At present, some factories use special tower foot welding robots to automatically weld the tower feet, such as a tower foot robot automatic welding device disclosed in application number CN202221056508.X, which fixes the tower foot that has been initially spot-welded with a cross, and then welds and fixes the tower foot through the robot body. During the welding process of the robot body, the cross is rotated by the rotating motor and the rotary reduction motor to adjust the position of the tower foot.

[0003] During the welding process of the robot body to the tower foot, the static electricity generated by the tower foot can easily affect the welding position quality of the weld. Therefore, the tower foot needs to be grounded before welding. The current common method is to use a separate grounding electrode clamp to fix it on the base plate of the tower foot. The grounding electrode clamp is grounded through a wire. In this way, the grounding electrode clamp and the wire are easily driven to move disorderly during the rotation of the tower foot base plate, which interferes with the welding operation of the robot body.

[0022] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0023] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] In this utility model, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integration; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or an interaction between two components. However, the phrase "direct connection" indicates that the two connected entities are not connected through an intermediate structure, but are connected to form a whole through a connecting structure. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0025] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0026] In this utility model, if Figure 1-3 As shown, an anti-static tower foot welding robot fixing device is provided, including a first bracket 1 that can rotate around a horizontal axis, a second bracket 2 that can be rotatably mounted on the first bracket 1, the second bracket 2 is perpendicular to the horizontal axis around the rotation axis of the first bracket 1, the second bracket 2 is provided with a fixing mechanism capable of fixing the tower foot base plate, and the second bracket 2 is configured as a metal bracket. The fixing device includes: a conductive disk 3, which is mounted on the side of the second bracket 2 facing the first bracket 1, and is configured to be conductive between the conductive disk and the second bracket 2; a lead electrode, which is arranged between the conductive disk 3 and the first bracket 1, including a sleeve 4 connected to the first bracket 1, a conductive rod 5 slidably arranged on the sleeve 4, an elastic member arranged between the conductive rod 5 and the sleeve 4, and a wire electrically connected to the conductive rod 5, the conductive rod 5 having an abutting end 501 extending outward from the sleeve 4, and the elastic member provides a force for the conductive rod 5 to extend outward so that the abutting end 501 can abut against the conductive disk 3.

[0027] When the fixing device of the present invention is used, the tower foot is initially spot-welded and then fixed to the fixing mechanism of the second bracket 2. During the welding process, the position and angle of the tower foot fixed to the second bracket 2 can be adjusted by rotating the second bracket 2 relative to the first bracket 1 and the first bracket 1 around the horizontal axis. The present invention forms an electrostatic conduction circuit between the tower foot, the second bracket 2, the conductive disc 3, and the conductive rod 5 by contacting the conductive rod 5 with the conductive disc 3 and setting electrical conductivity between the conductive disc 3 and the second bracket 2. This can timely conduct static electricity from the tower foot, thereby further ensuring the quality of welding.

[0028] Among them, the utility model sets a conductive disk 3, so that when the second bracket 2 rotates relative to the first bracket 1, the conductive disk rotates to maintain contact with the conductive rod 5, and the lead electrode is fixed at the position of the first bracket 1. Compared with the existing technology, the disordered movement of the wires caused by the linkage wires when the second bracket 2 rotates can be reduced, thereby reducing the interference with welding caused by the disordered movement of the wires.

[0029] It should be noted that the improvement of the present invention lies in the structure for extracting static electricity in the fixing device of the tower foot welding robot. There is no restriction on the improvement of other structures of the tower foot welding robot. An example of these other components is provided in the illustrated embodiment. It is further explained here that it should be understood that the present invention is not limited to the form shown in the drawings for the other structures described.

[0030] Specifically, support columns are provided at both ends of the first bracket 1, and support columns are provided at both ends of the first bracket 1. A motor for driving the first bracket 1 to rotate is provided in one of the support columns, and the first bracket 1 is a frame structure; the main structure of the second bracket 2 is cross-shaped, and the second bracket 2 is configured as a steel frame. The fixing mechanism of the second bracket 2 includes two groups of intersecting screw slider assemblies, and a single screw slider assembly includes screw segments with opposite rotation directions at both ends, and each screw segment is respectively provided with a slider, and the slider is provided with a threaded hole, so that the base plate of the tower foot can be fixed through the threaded hole; a base is provided at the bottom of the support column, and the base is also fixed with a mounting column of the welding robot body.

By adjusting the depth of screwing the adjusting bolt 7, the contact force between the conductive rod 5 and the conductive disk 3 can be adjusted.

[0037] As shown in the figure, by extending the lower end of the conductive rod 5 to the outside of the sleeve 4, the connection between the wire and the conductive rod 5 can be easily observed and adjusted. By setting the limit nut 8, not only can the limit nut 8 be used to assist the connection between the wire and the conductive rod 5, but also when the sleeve 4 is separated from the second bracket 2, the conductive rod 5 can be prevented from falling out from the upper side of the sleeve 4.

[0041] As shown in the figure, by such an arrangement, the wires and the lines of the drive motor can be led out after coordinated wire bundle management in the drive cabinet 9, thereby facilitating the management of the lines of the entire device.

[0042] In a specific embodiment, the various lines and wires can be bundled together in the drive cabinet 9 and led out, and the bundle can be led out along the frame 101 of the first bracket 1 to the support column position on one side and connected to the outside world (preferably, it can be led out from the support column on the side where the motor is not set and the rotation connection position of the first bracket 1, so that the first bracket 1 can rotate at least one circle around the horizontal axis).
