Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding tongs, in particular to a coaxial robot welding tongs. Background Art
[0002] With the continuous development of the automotive industry, the requirements for automotive production processes are increasing year by year. Welding accounts for the largest proportion of these production processes. Through welding, parts of different shapes and materials can be combined to meet the desired shape, performance, and other requirements of mechanical products. Compared to arc welding, spot welding technology offers advantages such as the absence of welding materials, the generation of no harmful fumes, a high welding cycle, low welding stress, and no damage to the workpiece's internal structure. This has led to its widespread use in the welding of body-in-white stamping panels. Depending on the tooling and panel, the welding tongs currently used in spot welding technology are generally categorized as C-type, X-type, and single-sided. The recent development of industrial robotics has significantly increased the level of automation in the welding field. Consequently, robot-driven automatic welding tongs are increasingly being used in production.
[0003] The electrode arms of existing coaxial robot welding tongs are mostly connected and fixed to the welding arms by screws, which makes it impossible to quickly replace the electrode arms, affecting the normal operation of the production line. Therefore, the applicant has made a beneficial design and found a solution to the above problem. The technical solution to be introduced below was produced in this context. Summary of the Invention
[0004] The purpose of the utility model is to overcome the shortcomings of the above-mentioned traditional coaxial robot welding clamp design and provide a product with quick replacement, simple operation and stable connection.
[0005] In order to solve the above problems, the present invention adopts the following technical solutions.
[0006] A coaxial robot welding clamp includes a mounting frame and a welding arm, wherein the mounting frame is provided with a movable electrode arm that can move forward and backward, and the welding arm is provided with a static electrode arm and is located on the movable track of the movable electrode arm, the mounting frame and the welding arm are provided with a support plate, and the support plate is provided with a liftable pressure plate, and the support plate and the pressure plate are provided with a contact surface that wraps the movable electrode arm and the static machine arm, and a fixing groove is provided on one side of the movable electrode arm and the static electrode arm, and the contact surface of the pressure plate is provided with a fixing block and is embedded in the fixing groove.
[0007] Preferably, guide rods are provided on both sides of the pressing plate and pass through the supporting plate.
[0008] Preferably, a pressure plate is provided between the guide rods, and the pressure plate is provided with a hollow column that wraps the guide rod. A spacing is left between the bottom of the hollow column and the support plate for separating the fixing blocks and the fixing grooves. A spring is provided on the outer wall of the hollow column, and the springs respectively abut the pressure plate and the support plate.
[0009] Preferably, the pressure plate is provided with a screw and is threadedly connected to the support plate. The outer wall of the screw is provided with a limiting portion, and the end face of the screw is provided with an operating portion.
[0010] Preferably, the fixing block is arranged at the entrance of the contact surface of the pressure plate.
[0011] Beneficial effects:
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] (1) The utility model has a fool-proof design during installation by setting fixing grooves on the moving electrode arm and the static electrode arm and cooperating with fixing blocks. After installation, the moving electrode arm and the static electrode arm are placed on the same axis, and no further debugging is required, which greatly reduces the time required for replacing the moving and static electrode arms. By rotating the operating part to raise the pressure plate, the fixing block is separated from the fixing groove, and the connection between the moving electrode arm, the static electrode arm and the mounting frame and the welding arm is released. No other disassembly tools are needed, and the moving and static electrode arms can be quickly replaced. The operation is simple, and the learning cost is reduced.
[0014] (2) The utility model applies the elastic force of the spring to the pressure plate, pressing the movable electrode arm and the static electrode arm tightly against the contact surface of the support plate. This is a one-time fixation. The fixing block is embedded in the fixing groove, which not only prevents the movable electrode arm and the static electrode arm from rotating during operation, but also prevents the movable electrode arm and the static electrode arm from being separated from the mounting frame and the welding arm, so that the product has the advantage of stable connection.

DETAILED DESCRIPTION
[0022] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships 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 direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0024] In the embodiments of the present invention, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0026] It is worth mentioning that guide rods 7 are provided on both sides of the pressing plate 4 and pass through the supporting plate 3. The guide rods 7 are used to guide the lifting of the pressing plate 4 so that the contact surface 5 of the pressing plate 4 and the contact surface 5 of the supporting plate 3 are on the same center line. The shape of the contact surface 5 is arc-shaped.
[0027] It is worth mentioning that a pressure plate 84 is provided between the guide rods 7, and the pressure plate 84 is provided with a hollow column 81 that wraps the guide rod 7. A spacing of a fixing block 51 separating the fixing groove 6 is left between the hollow column 81 and the bottom of the support plate 3. A spring 82 is provided on the outer wall of the hollow column 81, and the spring 82 abuts against the pressure plate 84 and the support plate 3 respectively. The elastic force of the spring 82 is applied to the pressure plate 4, pressing the movable electrode arm 11 and the static electrode arm 21 tightly against the contact surface 5 of the support plate 3. This is a one-time fixation. The fixing block 51 is embedded in the fixing groove 6, which not only prevents the movable electrode arm 11 and the static electrode arm 21 from rotating during operation, but also prevents the movable electrode arm 11 and the static electrode arm 21 from being disconnected from the mounting frame 1 and the welding arm 2.

The dynamic and static electrode arms 21 can be quickly replaced without borrowing other disassembly tools, and the operation is simple, which reduces the learning cost. The limiting portion 91 limits the range of motion of the screw 9;
[0029] It is worth mentioning that the fixing block 51 is arranged at the entrance of the contact surface 5 of the pressure plate 4 . This design is used to prevent the movable electrode arm 11 and the static electrode arm 21 from being disconnected from the contact surface 5 .
