Description

Technical Field

[0001] The utility model belongs to the technical field of welding, in particular to a welding robot workstation with an adjustment component. Background Art

[0002] An industrial robot is a multi-purpose, reprogrammable automatic control manipulator with three or more programmable axes, used in the field of industrial automation. In order to adapt to different uses, the mechanical interface of the robot's last axis is usually a connecting flange, which can be connected to different tools or end effectors. A welding robot is an industrial robot that is equipped with a welding clamp or welding gun on the end axis flange, enabling it to perform welding, cutting or thermal spraying. Since welding robots can avoid burns, electric shocks, vision damage, inhalation of toxic gases, excessive ultraviolet radiation and other dangers to operators during welding operations, welding robot workstations are widely used in different fields.

[0003] At present, most of the existing welding robot workstations are fixed and lack corresponding adjustment mechanisms to adjust the position of the welding robot workstations. When the welding robot workstation is welding the workpiece, the workpiece needs to be moved to the position of the workstation and then transported out after welding. The operation is relatively cumbersome. For the welding of some steel structures, welding needs to be carried out near the construction site for the construction use of the steel structure. However, the fixed welding robot workstation cannot meet the use needs of on-site welding and the use effect is not good.

[0004] To address the above problems, we propose a welding robot workstation with an adjustment component. Utility Model Content

DETAILED DESCRIPTION

[0025] This embodiment is a welding robot workstation with an adjustment component, such as Figure 1-Figure 7 As shown, the welding robot workstation with an adjustment component includes a processing table 1 and a mobile base 2. Several support rods 3 are fixed between the bottom of the processing table 1 and the mobile base 2. A mounting plate is fixed to the rear end of the processing table 1, and a mechanical arm 4 is mounted on the mounting plate. A welding gun 5 is mounted on the movable end of the mechanical arm 4. A positioning component is provided on the processing table 1, and an adjustment component is provided at the bottom of the mobile base 2. The adjustment component includes:

[0026] Axle 6, a plurality of vertical plates are fixed to the bottom of the mobile base 2, and the axle 6 rotates with two adjacent vertical plates;

[0027] The roller 7 and the limiting member are installed at the end of the wheel shaft 6, and the limiting member is arranged at the bottom of the mobile base 2 and cooperates with the wheel shaft 6 and the roller 7.

[0028] In the above structure, the positioning assembly is used to facilitate the positioning and clamping of the workpiece to be welded, thereby ensuring the stability of the workpiece during the welding process. The welding operation is facilitated by the combination of the robotic arm 4 and the welding gun 5. The roller 7 and the axle 6 cooperate with each other, and are combined with the mobile base 2 to facilitate the movement of the processing table 1, thereby achieving the purpose of adjusting the position of the processing table 1 and adapting to the welding use at the steel structure construction site. At the same time, under the action of the limiting member, the axle 6 and the roller 7 are conveniently limited and fixed, thereby ensuring the stability of the bottom of the mobile base 2, thereby ensuring the overall stability of the workstation during the welding process.

[0029] The limiting parts include a cylinder 8, a fixed block 9, a slider 11, a connecting arm 12, a strip plate 13, a first clamping block 14, a fixed rod 15, a second clamping block 16 and a return spring 17. A mounting groove is provided at the bottom of the mobile base 2, the cylinder 8 is installed inside the mounting groove, the fixed block 9 is connected to the telescopic end of the cylinder 8, and T-shaped sliding grooves 10 are provided on both sides of the mounting groove. The slider 11 is slidably arranged inside the sliding groove 10, and the two ends of the connecting arm 12 are respectively hingedly connected to the bottom of the slider 11 and the fixed block 9.

[0030] The strip plate 13 is fixed to the bottom of the slider 11, and the side of the strip plate 13 close to the wheel axle 6 is fixedly connected to the first clamping block 14 through a connecting rod. The first clamping block 14 is an arc-shaped structure and cooperates with the wheel axle 6. The two fixing rods 15 are relatively fixed on the two side surfaces of the strip plate 13, and the second clamping block 16 is fixed to the end of the fixing rod 15 away from the strip plate 13. The second clamping block 16 cooperates with the roller 7. The return spring 17 is arranged on the side of the slider 11 close to the cylinder 8, and the two ends of the return spring 17 are respectively fixed to the slider 11 and the inner wall of the slide groove 10.

[0031] The cylinder 8 extends outward, driving the fixed block 9 away from the mobile base 2. Under the hinged action at both ends of the connecting arm 12 and the elastic action of the return spring 17, the slider 11 is pulled toward the cylinder 8, and combined with the strip plate 13, the first clamping block 14 is driven to approach the wheel axle 6 until the first clamping block 14 is in contact with the outer wall of the wheel axle 6, thereby limiting and fixing the wheel axle 6. At the same time, under the action of the fixing rod 15, the second clamping block 16 is driven to be in contact with the outer wall of the roller 7, thereby limiting and fixing the roller 7, thereby ensuring the stability of the bottom of the mobile base 2 and the overall stability of the welding robot workstation when the welding operation is carried out.

[0032] The positioning assembly includes a placement table 18, a screw rod 19, a clamping plate 20, and a handwheel 21. The two placement tables 18 are arranged on the top of the processing table 1 relative to each other. The screw rod 19 rotates with the placement table 18. There are two through slots on the placement table 18. Two movable plates are threaded on the screw rod 19. The thread directions of the threaded holes in the center of the two movable plates are opposite. The upper end of the movable plate passes through the through slot and is fixedly connected to the clamping plate 20. The handwheel 21 is connected to the front end of the screw rod 19. Two T-shaped limit slots are relatively opened on the top of the placement table 18. Two T-shaped limit blocks are fixed to the bottom of the clamping plate 20, which are respectively movably matched with the two limit slots, effectively limiting and guiding the clamping plate 20. The stability of the clamping plate 20 during movement is ensured.

[0033] Movable pull rods 22 are fixed on both sides of the processing table 1 to facilitate pulling the processing table 1 to move. A guide rod is fixed inside the slide groove 10. The guide rod passes through the slider 11. The slider 11 slides with the guide rod to effectively limit and guide the slider 11. The reset spring 17 is mounted on the outside of the guide rod.

[0034] Example:

[0035] In the initial state, the cylinder 8 is in a retracted state, the first clamping block 14 and the second clamping block 16 are both located away from the axle 6 and the roller 7, and the return spring 17 is in a stretched state;

[0036] During use, when the position of the welding robot workstation needs to be adjusted, the processing table 1 is pulled to a suitable position by the movable pull rods 22 on both sides, in combination with the axle 6 and the roller 7, so as to achieve the purpose of adjusting the position of the welding robot workstation and adapt to different use environments;

[0037] Then the cylinder 8 is started, and the cylinder 8 extends outward, driving the fixed block 9 away from the movable base 2. Under the hinged action of the two ends of the connecting arm 12 and the elastic action of the return spring 17, combined with the sliding cooperation between the slider 11 and the guide rod, the slider 11 is pulled steadily toward the direction of the cylinder 8, and cooperates with the strip plate 13, thereby driving the first clamping block 14 to approach the wheel axle 6 until the first clamping block 14 is in contact with the outer wall of the wheel axle 6, thereby limiting and fixing the wheel axle 6.

[0038] At the same time, under the action of the fixing rod 15, the second clamping blocks 16 on both sides are respectively attached to the outer walls of the corresponding rollers 7, which limits and fixes the rollers 7, ensuring the stability of the bottom of the mobile base 2, and further ensuring the stability of the entire welding robot workstation during the welding operation;

[0039] When welding, first place the two workpieces to be welded on the placement tables 18 on both sides, and make the ends of the workpieces close to each other butt together. Then, turn the hand wheel 21 to drive the screw rod 19 to rotate. Under the mutual cooperation between the movable plate and the through slot, and the mutual cooperation between the limit block and the limit slot, the clamping plates 20 on both sides are driven to approach each other stably until they are clamped on both sides of the workpiece, so that the workpiece is limited and fixed at the center position of the placement table 18.

[0040] Finally, under the cooperation of the robot arm 4 and the welding gun 5, welding operation is performed on the butt joint of the two workpieces.

[0041] Compared with the existing fixed welding robot workstation, the utility model moves the entire workstation through the adjustment component to achieve the purpose of adjusting the position of the workstation, which solves the problem that most existing welding robot workstations are fixed and lack corresponding adjustment mechanisms. The position of the welding robot workstation is adjusted so that the welding robot workstation needs to move the workpiece to the position of the workstation when welding the workpiece, and then transport it out after welding is completed, which is a relatively cumbersome operation. It is suitable for the use needs of nearby welding of steel structures at the construction site and is convenient for the construction and use of welded steel structures.

[0042] It should be further explained that the installation structure, connection method or setting method of each component in the present invention are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented. At the same time, the cylinder 8 in the present invention is purchased on the market, and those skilled in the art can install and use it according to the requirements;

[0043] Meanwhile, the robotic arm 4 and the welding gun 5 in the present invention are both commonly used mechanical components in the field of automated welding technology, and their specific structures, working principles and usage methods are not described in detail here.

[0044] All technical features in this embodiment can be freely combined according to actual needs.
