Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a fixed workbench for perforated plug welding. Background Technology

[0002] Plug welding, a mature welding technology, is widely used in various fields such as machinery manufacturing, construction engineering, and bridge construction. Its basic principle involves pre-drilling holes in the workpiece, inserting the reinforcing steel bar or similar structural component to be welded into the holes, and then using welding equipment (such as arc welding or gas shielded welding) to achieve a firm connection between the reinforcing steel bar and the workpiece within the holes. This welding method not only enhances the connection strength between structural components but also effectively disperses stress, improving the stability and durability of the overall structure.

[0003] With the rapid development of industrial automation technology, traditional manual or semi-automatic piercing and plug welding processes can no longer meet the demands of modern high-efficiency and precise production. Firstly, in actual production, the diameter and length of reinforcing bars vary widely, and different specifications of reinforcing bars require different welding parameters, positioning accuracy, and clamping methods during piercing and plug welding. Traditional workbenches often struggle to adapt to this diversity, leading to low welding efficiency and inconsistent quality. Secondly, automated production lines pursue efficient and continuous production processes, which requires the piercing and plug welding process to be fast and accurate, minimizing manual intervention and reducing error rates. Traditional workbenches often require significant manual operation in areas such as reinforcing bar positioning, clamping, and welding parameter adjustment, making it difficult to meet the efficiency and precision requirements of automated production lines.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see the appendix Figure 1-6This embodiment of the perforated plug welding fixing workbench includes a frame 1, a longitudinal gripping component 2 inside the frame 1, a three-axis motion platform 3 connected below the longitudinal gripping component 2, a platform 4 above the longitudinal gripping component 2, the platform 4 being fixedly connected to the frame 1, a feeding groove 5 on the platform 4 for the gripping mechanism to feed material, pressure rods 6 and upper push rods 7 symmetrically arranged on both sides of the feeding groove 5, a driving component installed between the pressure rods 6 and the platform 4, the driving component driving the pressure rods 6 to apply a clamping force to the anchor plate, a sliding table 8 between the upper push rod 7 and the platform 4, the upper push rod 7 and the sliding table 8 cooperating to limit the vertical displacement of the longitudinal gripping component 2.

[0025] The frame 1 is an outer frame structure located below the platform 4, used to support the platform 4 and internal components. The sides of the frame 1 are equipped with a material handling robot, a material unloading robot, and a welding robot. The longitudinal gripping component 2 is located inside the frame 1. The longitudinal gripping component 2 is used to grip the reinforcing bars, which are placed vertically on it. The three-coordinate motion platform 3 has three degrees of freedom of sliding. Through the cooperation of the three-coordinate motion platform 3 and the longitudinal gripping component 2, the reinforcing bars can be moved to any position in space, thus ensuring that the reinforcing bars are located at their designated points during perforation and plug welding. The longitudinal gripping component 2 is located below the platform 4. To prevent the platform 4 from interfering with the movement of the reinforcing bars, a feeding groove 5 is provided on the platform 4. Anchor plates for welding with the reinforcing bars span across the feeding groove 5. Furthermore, to allow the feeding groove 5 to cooperate with anchor plates of different widths, the width of the front and rear sides of the feeding groove 5 differs in a stepped manner. The anchor plate above 5 is pressed by the pressure rod 6. There are two sets of pressure rods 6 and upper push rods 7. The positions of the pressure rods 6 and upper push rods 7 on the left and right sides are exactly opposite. A drive assembly is installed between the pressure rod 6 and the platform 4. The drive assembly drives the pressure rod 6 to apply downward pressure to the anchor plate, thereby increasing the force between the anchor plate and the platform 4 and fixing the anchor plate on the platform 4. The upper push rod 7 is located on one side of the pressure rod 6. Under the action of the slide table 8, the upper push rod 7 will move to the top of the through hole of the anchor plate. The central axis of the upper push rod 7 is on the same vertical line as the hole axis of the through hole of the anchor plate. After the steel bar passes through the through hole, it will contact the upper push rod 7. The upper push rod 7 restricts the upward movement of the steel bar. A positioning sensor is installed on the upper push rod 7. After receiving the feedback signal from the positioning sensor, the longitudinal gripping assembly 2 moves upward. Then, after the steel bar contacts the upper push rod 7, the longitudinal gripping assembly 2 stops. At the same time, the welding robot senses the position of the upper push rod 7 and performs welding.

[0026] The longitudinal gripping assembly 2 contains two clamping claws 201. These claws are positioned close to or far apart from each other. The claws are driven by a clamping cylinder 203. A guide rod between the clamping cylinder 203 and the claws guides the movement of the two claws, ensuring that their clamping centers are on the same horizontal line. To improve the stability of the longitudinal gripping assembly 2 in clamping the reinforcing bar, three sets of claws 201 are used. These three sets clamp the lower, middle, and upper parts of the reinforcing bar respectively, preventing it from swaying.

[0027] The main body of the three-coordinate motion platform 3 consists of three mutually perpendicular X-axis guide rails 301, Y-axis guide rails 302, and Z-axis guide rails 303. Each of the three guide rails has a power device that drives its movement. The first base 304 is slidably connected to the Y-axis guide rail 302 and moves back and forth along the Y-axis. The back and forth sliding of the first base 304 drives the X-axis guide rail to move back and forth. Similarly, the second base 305 can move left and right on the X-axis guide rail. The left and right movement of the second base 305 drives the Z-axis guide rail to move left and right. The third base 306 can move vertically on the Z-axis guide rail. The vertical movement of the third base 306 can drive the vertical movement of the longitudinal gripping component 2, thereby giving the longitudinal gripping component 2 flexible movement capability under the platform 4, ensuring that the steel bars are transferred to the designated location.

[0028] The telescopic rod 11 is pneumatically or hydraulically driven. The middle part of the telescopic rod 11 is hinged to the fixed plate 10, and the telescopic end of the telescopic rod 11 is hinged to the linkage rod assembly. The telescopic rod 11 is the power source, and the linkage rod assembly restricts the movement trajectory of the pressure rod 6. Through the telescopic rod 11 and the linkage rod assembly, the pressure rod 6 is vertically applied to the anchor plate. The linkage rod assembly includes a first connecting rod 12, a second connecting rod 13, and an adjusting connecting rod 9. Figure 6 As shown, the first link 12 is located inside the second link 13. When the telescopic rod 11 extends, the first link 12 and the second link 13 swing to the right. The rightward swing of the hinge point at the upper end of the first link 12 will cause the first link 12 to press down on the middle of the adjusting link 9. The adjusting link 9 will drive the pressure rod 6 to press down. Conversely, when the telescopic rod 11 retracts, the adjusting link 9 will drive the pressure rod 6 to release the pressure on the anchor plate.

[0029] The pressure rod 6 consists of four parts: an adjustable pressure head 601, an adjusting screw 602, a locking block 603, and a locking nut 604. The locking block 603 has a slot and a through hole. The slot is locked onto the end of the adjusting connecting rod 9. The adjusting screw 602 passes through the through hole and penetrates the locking block 603. The locking nuts 604 at both ends of the locking block 603 fix the locking block 603 to the adjusting screw 602. By adjusting the length of the adjusting screw 602 through the through hole, the distance between the adjustable pressure head 601 and the adjusting connecting rod 9 can be adjusted. This ensures that after the adjusting connecting rod 9 rotates, the bottom surface of the adjustable pressure head 601 can be pressed horizontally under the anchor plate, increasing the contact area between the two.

[0030] The slide table 8 that fixes the upper push rod 7 has a Z-shaped structure. The slide table 8 can move laterally on the slide rail 15 via the second cylinder 16 below it, so that the upper push rod 7 can correspond to different anchor plate through holes. The first cylinder 14 on the slide table 8 can drive the upper push rod 7 to move vertically, so as to adjust the distance of the steel bar passing through the through hole and improve the flexibility of the device.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
