Description

Technical Field

[0001] The utility model relates to the technical field of welding devices, and particularly relates to a multi-guardrail integral welding device. Background Art

[0002] A door and window frame is composed of multiple guardrail bars. The multiple guardrail bars are sequentially placed on an automatic positioner and clamped and fixed by a fixture on the automatic positioner. Then, a welding robot welds the connection positions of the multiple guardrail bars to form an integral whole, thereby forming a door and window frame. After one-side welding is completed, the automatic positioner flips the door and window frame, and then welds and connects the connection positions on the other side. After welding is completed, the automatic positioner resets, and then the welded door and window frame is removed from the automatic positioner. The welding torch of the welding robot is fed with wire by a wire spool. The wire spool is sleeved on a central shaft, and then a knob is tightened on the central shaft to achieve the positioning of the wire spool and prevent axial displacement of the wire spool on the central shaft.

[0003] When a common multi-guardrail integral welding device is in use, the wire spool is sleeved on the central shaft of the welding robot, and the wire spool is positioned by a knob. After the wire on the wire spool is used up, it needs to be replaced. When replacing, the knob needs to be unscrewed from the end of the central shaft first, and then the used-up wire spool is removed from the central shaft. Then, a new wire spool is sleeved on the central shaft, and then the knob is screwed on the end of the central shaft and tightened to achieve the positioning of the wire spool. However, in the actual use process, when the knob is tightened too tightly, it will hinder the normal rotation of the wire spool on the central shaft. When it is screwed too loosely, the wire spool will have axial displacement on the central shaft, thus affecting the stable wire feeding to the welding robot. Therefore, the present application provides a multi-guardrail integral welding device to meet the requirements. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a multi-guardrail integral welding device to solve the technical problem that it is difficult to accurately position the wire spool, thereby stably feeding wire to the welding robot.

[0015] In the above solution, through the arrangement of the clamping block, the pressing ring and the circular ring, the square bar is inserted into the lower groove and the clamping block is stuck in the clamping groove. At this time, the square bar is pressed by the pressing block to prevent the clamping block from separating from the clamping groove. Then, the square bar drives the pressing ring to press on the side of the wire reel through the circular ring, realizing the accurate positioning of the wire reel. There is no need to use a knob for positioning, so that the normal rotation of the wire reel will not be affected, and the rotation of the wire reel is smoother, thus realizing the stable wire feeding for the welding robot.

[0016] With the provision of the arc-shaped handle and the straight-shaped handle, when it is necessary to remove the wire spool, hold the arc-shaped handle and the straight-shaped handle simultaneously, and lift the square bar forcefully in the direction of the straight-shaped handle, so that the square bar drives the clamping block to separate from the clamping groove.

[0028] Such as Figures 1 - 4As shown in the figure, an embodiment of the utility model provides a multi-guardrail integral welding device, including an automatic positioner 1 and a welding robot 2. The automatic positioner 1 is used for positioning and flipping the door and window frame, and the welding robot 2 is used for welding the door and window frame. Place multiple guardrail rods on the automatic positioner 1 in sequence, realize the positioning of multiple guardrail rods through the automatic positioner 1, and then use the welding robot 2 to weld and connect the door and window frame composed of multiple guardrail rods. After one-side welding is completed, the automatic positioner 1 drives the door and window frame to flip, and then the connection parts of multiple guardrail rods on the other side can be welded. After welding is completed, the door and window frame can be removed from the automatic positioner 1 after releasing the positioning of the door and window frame. A shield 4 is fixed on the welding robot 2, a central shaft 5 is fixed on the side of the inner wall of the shield 4, a wire reel 3 is sleeved on the central shaft 5, and when the wire reel 3 rotates, it rotates around the surface of the central shaft 5. Upper grooves 17 and lower grooves 18 are respectively formed at the end parts of the central shaft 5, the upper grooves 17 and the lower grooves 18 are communicated with each other, and a square bar 7 is slidably connected in the lower groove 18. The width of the upper groove 17 is greater than the width of the lower groove 18. A clamping block 8 is fixed at the bottom of the square bar 7, and a clamping groove 19 is formed at the bottom of the inner wall of the lower groove 18. The clamping block 8 is stuck in the clamping groove 19. An elastic pressing member 6 is arranged on the square bar 7. A pressing ring 11 is attached to the side of the wire reel 3. A circular ring 9 is arranged on the side of the pressing ring 11. The pressing ring 11 is rotatably connected to one side of the circular ring 9 close to the wire reel 3. A plurality of vertical rods 16 are fixed on the inner wall of the circular ring 9, and the end parts of the vertical rods 16 are fixedly connected with the side of the square bar 7. After the clamping block 8 is stuck in the clamping groove 19, the square bar 7 can drive the pressing ring 11 to press on the side of the wire reel 3 through the cooperation of the vertical rods 16 and the circular ring 9, so as to realize the accurate positioning of the wire reel 3, make the rotation of the wire reel 3 smoother, and thus realize the stable wire feeding of the welding robot 2.

[0029] As Figure 3 shown, in this embodiment, the elastic pressing member 6 includes a spring 62 fixed to the top of the inner wall of the upper groove 17. The bottom of the spring 62 is fixed with a pressing block 61. The side of the pressing block 61 is slidably connected to the side of the inner wall of the upper groove 17. The pressing block 61 presses on the square bar 7. The pressing block 61 presses on the square bar 7 under the elastic force of the spring 62, so as to prevent the clamping block 8 from separating from the clamping groove 19.

[0030] As Figure 3 shown, in this embodiment, inclined surfaces are arranged at the bottom of the pressing block 61 and the bottom of the inner wall of the lower groove 18. When the square bar 7 is inserted into the central shaft 5, through the guidance of the inclined surfaces, it is convenient for the square bar 7 to be inserted into the central shaft 5.

[0031] As Figure 3As shown in the figure, in this embodiment, a positioning disk 14 is fixedly sleeved on the surface of the square bar 7. The positioning disk 14 fits against the end of the central shaft 5. After the positioning disk 14 fits against the end of the central shaft 5, the clamping block 8 is aligned with the position of the clamping groove 19. At this time, the square bar 7 can be moved downward to make the clamping block 8 stuck in the clamping groove 19. After the clamping block 8 is stuck in the clamping groove 19, the pressing ring 11 can be made to fit against the side surface of the wire spool 3, thereby achieving accurate positioning of the wire spool 3.

[0032] As Figure 3 shown in the figure, in this embodiment, a T-shaped ring 12 is fixed on the side surface of the pressing ring 11. An annular groove is formed on the side surface of the circular ring 9. The surface of the T-shaped ring 12 is rotatably connected to the inner wall of the annular groove. When the wire spool 3 drives the pressing ring 11 to rotate, the pressing ring 11 drives the T-shaped ring 12 to rotate along the inner wall of the annular groove. The rotation connection between the circular ring 9 and the pressing ring 11 is realized through the T-shaped ring, and the separation between the circular ring 9 and the pressing ring 11 is prevented.

[0033] As Figure 2 shown in the figure, in this embodiment, a plurality of pressing plates 13 are fixed on the circumferential surface of the pressing ring 11. The pressing plates 13 fit against the side surface of the wire spool 3. By means of the pressing plates 13, the contact area between the pressing ring 11 and the side surface of the wire spool 3 is increased, thereby achieving stable and reliable positioning of the wire spool 3.

[0034] As Figure 3 shown in the figure, in this embodiment, an arc-shaped handle 15 and a straight handle 20 are respectively fixed on the side surfaces of two relatively arranged vertical rods 16. While holding the arc-shaped handle 15 and the straight handle 20 at the same time and applying force to lift the square bar 7 in the direction of the straight handle 20, the clamping block 8 can be moved upward and separated from the clamping groove 19, thereby achieving convenient disassembly of the wire spool 3.

[0035] As Figure 3 shown in the figure, in this embodiment, a round rod 10 is fixed between the arc-shaped handle 15 and the straight handle 20. The round rod 10 connects the arc-shaped handle 15 and the straight handle 20 into a whole, thereby improving the structural strength at the arc-shaped handle 15 and the straight handle 20.

[0036] Working principle: A plurality of guardrails are sequentially placed on the automatic positioner 1. The automatic positioner 1 is used to position the plurality of guardrails. Then, a welding robot 2 is used to weld and connect the window and door frames composed of the plurality of guardrails. After the single-side welding is completed, the automatic positioner 1 drives the window and door frame to flip, and then the joints of the plurality of guardrails on the other side can be welded. During the welding process, the wire spool 3 supplies wire to the welding robot 2. When the wire on the wire spool 3 is used up, it needs to be replaced. When replacing, the wire spool 3 needs to be removed from the central shaft 5 first;

[0037] When removing the wire spool 3, hold the arc-shaped handle 15 and the straight handle 20 simultaneously, and lift the square bar 7 forcefully in the direction of the straight handle 20. When the square bar 7 moves upward, it drives the clamping block 8 to move upward and separate from the clamping groove 19. At the same time, the square bar 7 moves upward and squeezes the pressing block 61, causing the pressing block 61 to move upward along the inner wall of the upper groove 17 and compress the spring 62. When the spring 62 is in a compressed state and the clamping block 8 is separated from the clamping groove 19, the square bar 7 and the clamping block 8 can be pulled out from the central shaft 5. After pulling out, the ring 9 can drive the pressing ring 11 to separate from the wire spool 3 through the T-shaped ring 12, thus releasing the positioning of the wire spool 3. Then, the wire spool 3 can be removed from the central shaft 5, realizing the disassembly of the wire spool 3. The operation is simple, which is convenient for the disassembly of the wire spool 3;

[0038] When installing a new wire spool 3, put the wire spool 3 on the central shaft 5, then align the square bar 7 and the clamping block 8 with the position between the pressing block 61 and the lower groove 18. Hold the positions of the arc-shaped handle 15 and the straight handle 20, insert the square bar 7 into the lower groove 18. The square bar 7 squeezes the inclined surface at the bottom of the pressing block 61, causing the pressing block 61 to move upward along the inner wall of the upper groove 17 and compress the spring 62. When the spring 62 is in a compressed state, after inserting the square bar 7 into the lower groove 18 and making the end of the square bar 7 fit against the side surface of the inner wall of the lower groove 18, move the square bar 7 downward to make the clamping block 8 stuck in the clamping groove 19, and then release the arc-shaped handle 15 and the straight handle 20. At this time, the pressing block 61 presses on the square bar 7 under the elastic force of the spring 62, thus preventing the clamping block 8 from separating from the clamping groove 19. Then, the square bar 7 drives the pressing ring 11 to press on the side of the wire spool 3 through the cooperation of the vertical rod 16 and the ring 9, realizing the accurate positioning of the wire spool 3. When the wire spool 3 rotates on the central shaft 5, it drives the pressing ring 11 to rotate, and the pressing ring 11 drives the T-shaped ring 12 to rotate along the inner wall of the annular groove on the side of the ring 9, thus realizing the wire feeding to the welding robot 2. The above installation method is simple and convenient, which is convenient for the installation of the wire spool 3, and both the installation and disassembly of the wire spool 3 are convenient, so that while realizing the accurate positioning of the wire spool 3, it is also convenient for the replacement of the wire spool 3.

In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without the description of these details.

[0040] The above description is only the preferred embodiment of the present utility model.
