Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a safe welding robot that can improve the stability of the welding trajectory. Background Technology

[0002] Welding equipment is a processing platform used for welding operations. It is mainly used for welding and assembling various profiles. For profiles of different specifications, in order to ensure their stability during welding, it is usually necessary to use appropriate clamps for auxiliary clamping and limiting, so that the welding trajectory remains stable during welding.

[0003] According to a disclosed clamping device for welding machine tool housing (publication number: CN217618772U), the aforementioned patent includes a first clamping plate, a second clamping plate, an electric push rod, a first lead screw, a lead screw nut, a sliding sleeve, and a sliding rod. When the drive motor is operated by the controller, the two first clamping plates can be initially clamped and positioned for welding. The extension of the electric push rod can further position the second clamping plate for welding. The clamping position of the second clamping plate can be quickly and effectively adjusted left and right to prevent positional displacement during welding, further ensuring the clamping effect of the housing to be welded and facilitating the rapid and effective welding of the housing.

[0004] While the aforementioned equipment can perform quick and effective clamping and fixing in actual use, the rigid limiting of the object being welded at the clamp causes slight up-and-down sliding amplitude due to the force vibration of the welded object during welding, resulting in small deviations in the welding trajectory and instability. In view of this, we propose a safe welding robot that can improve the stability of the welding trajectory. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes a safe welding robot that can improve the stability of the welding trajectory.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0007] A safe welding robot with improved welding trajectory stability includes a worktable assembly, a welding assembly, a control assembly, and four sets of robotic arms, arranged in pairs (front and back) on the worktable assembly. The two outermost sets of robotic arms are equipped with detachable and installable limiting plates, and the remaining two sets of robotic arms have stabilizing components at their ends. The stabilizing components include:

[0008] A linear motion unit, which is fixed to the end of the robotic arm;

[0009] Mounting plate, which is driven to move by the linear motion unit;

[0010] A pressure head, which is fixedly connected to the side wall of the mounting plate near the object being welded;

[0011] The upper plate is fixedly connected to the top side wall of the mounting plate;

[0012] A flexible inclined plate, which is slidably mounted on the top sidewall of the mounting plate;

[0013] The pressure head is driven by the linear motion unit and moves to fit against the surface of the object being welded. During this movement, the object being welded will press against the flexible inclined plate in the opposite direction, so that the flexible inclined plate is pressed downward by the upper plate during the backward movement, thereby forming the effect of pressing and fixing the object being welded by the flexible inclined plate downward.

[0014] Preferably, the linear motion unit is a hydraulic telescopic rod, the mounting plate has an L-shaped structure, and the upper plate has an L-shaped structure.

[0015] Preferably, a sliding block is slidably connected to the top sidewall of the mounting plate, a spring is fixedly connected to the sliding block, and the bottom of the flexible inclined plate is fixedly connected to the sliding block.

[0016] Preferably, a mounting base is fixedly connected to the sliding block, and two fixing rubber plates are fixedly connected to the symmetrical sides of the mounting base. Two arc-shaped rubber blocks are fixedly connected to the outer walls of the two fixing rubber plates.

[0017] Preferably, the two fixing plates are distributed in a figure-eight shape on both sides of the center plane of the mounting base.

[0018] Preferably, two compression pins are fixedly connected to the mounting plate, and the two compression pins are located in the moving direction of the two arc-shaped rubber blocks.

[0019] Preferably, an arc-shaped adhesive strip is fixedly connected to the side wall of the flexible inclined plate near the welding object. Several arc-shaped adhesive strips are provided, and the several arc-shaped adhesive strips are arranged in a linear array on the outer wall of the flexible inclined plate.

[0020] Preferably, the mounting plate is provided with a clamping assembly, which includes a limiting groove on the top side wall of the mounting plate, a fixing sleeve fixedly connected to the outer inclined side wall of the flexible inclined plate, and a strike plate. A moving block is slidably connected to the fixing sleeve. A swing rod is fixedly connected to the top of the moving block and a sliding rod is fixedly connected to the bottom. A striking ball is fixedly connected to the end of the swing rod, and the sliding rod is slidably installed in the limiting groove.

[0021] Preferably, the limiting groove is arranged in a wave shape.

[0022] Preferably, the impact plate is located in the swing direction of the striking ball.

[0023] The beneficial effects of this utility model are:

[0024] This invention provides a safe welding robot that improves the stability of the welding trajectory. When the contact head moves, it causes the workpiece to press against the flexible inclined plate in the opposite direction. As the flexible inclined plate and the arc-shaped rubber strip move backward, they are pressed downward by the contact head, which in turn presses the workpiece downward and fixes it. When the arc-shaped rubber strip and the flexible inclined plate fix the workpiece on both sides at the same time, they can better center and limit the workpiece and press it downward, preventing the rigidly limited workpiece from floating slightly up and down due to vibration. This allows the fixing plate to limit the side wall of the workpiece in a figure-eight shape, ensuring that the workpiece is clamped and limited by multiple layers during welding, and further stabilizing the welding trajectory, thereby ensuring the safety of the welding operation.

[0025] When the sliding block and the flexible inclined plate move backward, the fixed sleeve will move synchronously, which will allow the sliding rod to move smoothly in the limiting groove. Through the transmission of the moving block and the swing rod, the striking ball can periodically strike the impact plate. In turn, the vibration will cause the arc-shaped rubber strip on the flexible inclined plate to rub against the welded material, which will further improve the bonding effect and ultimately increase the overall stability and safety.

[0036] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] like Figures 1 to 8 As shown, a safe welding robot that can improve the stability of the welding trajectory includes a robotic arm 1, a worktable assembly 2, a welding assembly 3, a limiting plate 4, a control assembly 5, and a stabilizing assembly 6.

[0038] In this embodiment, there are eight robotic arms 1, which are symmetrically arranged on the workbench assembly 2 in a row of four. The welding assembly 3 is located above the four middle robotic arms 1, and the control assembly 5 is located on the front side of the workbench assembly 2. There are two limiting plates 4, which are detachably installed on the four outermost robotic arms 1 and are arranged symmetrically from left to right.

[0039] The stabilizing components 6 are provided in four sets, corresponding to the ends of the four robotic arms 1 located in the middle. Each set of stabilizing components 6 includes a hydraulic telescopic rod 601, which is fixedly connected to the outer wall of the robotic arm 1. A mounting plate 602 is fixedly connected to the end of the hydraulic telescopic rod 601. The mounting plate 602 has an L-shaped structure. A pressing head 603 is fixedly connected to the outer wall of the mounting plate 602. An upper plate 604 and a pressing pile 612 are fixedly connected to the top outer wall of the mounting plate 602. The upper plate 604 has an L-shaped structure. A sliding groove is formed on the top outer wall of the mounting plate 602. A spring 605 is provided in the sliding groove, and a sliding block 606 is slidably installed therein. The spring 605 is connected to the sliding block 606. A flexible inclined plate 607 and a mounting base 609 are fixedly connected to the sliding block 606. An arc-shaped rubber strip 608 is fixedly connected to the inner inclined side wall of the flexible inclined plate 607. A fixing rubber plate 610 is fixedly connected to the mounting base 609. An arc-shaped rubber block 611 is fixedly connected to the outer wall of the fixing rubber plate 610. The extrusion pile 612 is located in the moving direction of the arc-shaped rubber block 611.

[0040] In an embodiment of this utility model, four arc-shaped adhesive strips 608 are provided. The four arc-shaped adhesive strips 608 are arranged in a linear array on the outer wall of the flexible inclined plate 607, so that they can better fit the welded body to be fixed.

[0041] In this embodiment of the utility model, the center line of the sliding block 606 and the center line of the flexible inclined plate 607 are on the same straight line, so that the sliding block 606 can smoothly drive the flexible inclined plate 607 to move; the number of fixed rubber plates 610 is two sets, and the two sets of fixed rubber plates 610 are distributed on both sides in a figure-eight shape with the center surface of the mounting base 609.

[0042] Furthermore, the mounting plate 602 is provided with a clamping assembly 7, which includes a limiting groove 701 opened on the top side wall of the mounting plate 602, a fixing sleeve 702 fixedly connected to the outer inclined side wall of the flexible inclined plate 607, and an impact plate 707. The limiting groove 701 is wavy. A moving block 703 is slidably connected to the fixing sleeve 702. A swing rod 704 is fixedly connected to the top of the moving block 703, and a sliding rod 706 is fixedly connected to the bottom. A striking ball 705 is fixedly connected to the end of the swing rod 704. The sliding rod 706 is slidably installed in the limiting groove 701. The impact plate 707 is located in the swing direction of the striking ball 705.

[0043] Working principle and usage process of this utility model:

[0044] In daily use, the control component 5 is used to control the movement of the robotic arm 1 and the limiting plate 4 to initially limit the welding object. Then, the robotic arm 1 and the stabilizing component 6 are moved to position the pressure head 603 on the side wall of the welding object. When the pressure head 603 is moved, the welding object will press against the flexible inclined plate 607 in the opposite direction. The flexible inclined plate 607 and the arc-shaped rubber strip 608 are pressed downward by the upper plate 604 during the backward movement. Then, the arc-shaped rubber strip 608 and the flexible inclined plate 607 press and fix the welding object diagonally downward, which can better center the limit and prevent the rigidly limited welding object from floating slightly up and down due to vibration.

[0045] Furthermore, during the backward movement of the flexible inclined plate 607, the sliding block 606 drives the fixed rubber plate 610 on the mounting base 609 to move synchronously, so that the arc-shaped rubber block 611 is further squeezed when it passes through the extrusion pile 612, making the fixed rubber plate 610 limit the side wall of the welded object in a "V" shape. At the same time, the fixed sleeve 702 moves synchronously, driving the sliding rod 706 to move smoothly in the limiting groove 701. Since the limiting groove 701 has a wave structure, the swing rod 704 performs a reciprocating swing action during the movement, causing the striking ball 705 to periodically strike the impact plate 707. In turn, the vibration causes the arc-shaped rubber strip 608 on the flexible inclined plate 607 to rub against the welded object, further improving the bonding effect, and ultimately increasing the overall stability and safety.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
