Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding auxiliary equipment technology, and in particular to a right-angle welding positioning device. Background Technology
[0002] In the welding field, welding operations where pipes and frames meet at 90 degrees are quite common. Currently, several problems arise when performing such welding operations. Firstly, manual support and positioning are extremely difficult. During welding, human factors can easily cause angle deviations or workpiece movement, directly affecting welding accuracy and making it difficult to guarantee welding quality. Secondly, when materials are not securely fixed, repeated adjustments are required, resulting in low work efficiency and unstable welding quality, failing to meet actual production needs. Furthermore, existing tooling equipment has poor adaptability to small-sized materials (diameter / width less than 100mm), lacking versatility. When welding small-sized materials of different specifications, different tooling is often required, increasing production costs and work difficulty. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings:
[0026] Example 1
[0027] like Figures 1-4 As shown, a right-angle welding positioning device includes a base plate 1. A first fixed frame 2 and a second fixed frame 10 perpendicular to each other are fixedly installed on the base plate 1. A limiting slide 3 that can slide along the direction of the first fixed frame 2 is provided at the end of the first fixed frame 2 near the second fixed frame 10. A retaining edge 16 is provided on the side of the first fixed frame 2 and the second fixed frame 10 that are close to each other. A clamping mechanism is provided on the side of the first fixed frame 2 and the second fixed frame 10 that are far away from each other. Guide wheels that facilitate workpiece installation are provided on the clamping mechanism and the retaining edge 16. The guide wheel includes a fixed shaft for connection and installation and a roller sleeved on the fixed shaft. The fixed shaft and the roller are connected by a one-way bearing.
[0028] The clamping mechanism includes a guide plate 5 fixedly mounted on the base plate 1. One end of the guide plate 5 is threadedly connected to a screw 6, and the upper surface of the other end of the guide plate 5 has a groove 14. A sliding block 15 is provided in the groove 14, and a slider 7 is fixedly mounted on the upper end of the slider 15. The end of the screw 6 near the slider 7 is connected to the slider 7 via a bearing. A fixing box 8 is fixedly mounted on the side of the slider 7 away from the screw 6. A knob is fixedly mounted on the end of the screw 6 away from the slider 7. The guide wheel on the flange 16 of the first fixing frame 2 is a straight guide wheel 9, and the guide wheel on the flange 16 of the second fixing frame 10 is a V-shaped guide wheel. V-shaped guide wheels 11; the fixing box 8 of the clamping mechanism corresponding to the first fixing frame 2 is located on the side of the first fixing frame 2 away from the side flange 16, and a straight guide wheel 9 is installed on the side of the fixing box 8 close to the side flange 16; the fixing box 8 of the clamping mechanism corresponding to the second fixing frame 10 is located on the side of the second fixing frame 10 away from the side flange 16, and a V-shaped guide wheel 11 is installed on the side of the fixing box 8 close to the side flange 16; the unidirectional rolling of the guide wheels ensures that the frame and the pipe can be quickly installed and fixed in place, and the V-shaped guide wheel 11 makes it easy to clamp the pipe in the middle position, which is convenient for positioning and meets the welding position requirements.
[0029] The upper surfaces of the guide plate 5, the first fixed frame 2, the second fixed frame 10 and the limiting slide 3 are all on the same plane, which ensures that the limiting slide 3 moves more smoothly and that pipes and frames are placed, and avoids the problem of sliding jamming caused by inconsistent heights.
[0030] A limiting baffle 17 for blocking the workpiece is fixedly installed on the upper surface of the limiting slide 3 away from the first fixed frame 2; a guide groove 12 is opened in the middle of the end of the first fixed frame 2 near the limiting slide 3; the end of the limiting slide 3 away from the limiting baffle 17 is locked in the guide groove 12 by the guide strips 13 on both sides of the limiting slide 3 and slides. A fixing screw 4 is provided on the side of the first fixed frame 2. The fixing screw 4 is connected to the first fixed frame 2 by threads, and one end of the fixing screw 4 extends into the guide groove 12 and presses against the guide strip 13.
[0031] Working principle: During use, according to the distance between the pipe to be welded on the frame and the end of the frame, slide the limiting slide 3 to the set position and tighten the fixing screw 4. The fixing screw 4 presses against the guide bar 13 to fix the limiting slide 3. Place the frame and the pipe to be welded against the first fixed frame 2 and the second fixed frame 10 respectively on the side rail 16. Turn the knob on the screw 6 to drive the slider 7 so that the guide wheel on the fixed box 8 and the guide wheel on the side rail 16 cooperate to clamp the workpiece. First push the frame, and the straight guide wheel 9 provides rolling support. The frame hits the limiting baffle 17. Since the straight guide wheel 9 rolls in one direction, the frame is fixed in the final position after sliding into place. Then push the pipe closer to the frame, and the V-shaped guide wheel 11 provides rolling support in one direction. Finally, the end of the pipe hits the frame and is fixed by the V-shaped guide wheel 11. The worker or welding robot can then perform the corresponding welding, replacing manual assistance and reducing the risk factor. After welding is completed, turn the screw 6 in the opposite direction to release the welded workpiece, and the workpiece can be removed.
[0032] Example 2
[0033] The difference between this embodiment and embodiment 1 is that: the upper surface of the first fixed frame 2 is provided with a scale line corresponding to the position of the limiting slide 3 to facilitate observation of the sliding distance of the limiting slide 3; the driving mechanism is an external motor that drives the screw 6 to rotate.
[0034] Working principle: When in use, the sliding distance of the limit slide 3 can be precisely adjusted by the scale line on the first fixed frame 2, and the screw 6 is driven by an external motor to rotate so that the clamping mechanism automatically clamps the workpiece, improving the positioning accuracy and work efficiency. After welding is completed, the workpiece is disassembled by reversing the operation.
[0035] Both the one-way bearing and the external motor are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.

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 only illustrative of the principles of this utility model.
