Description

Technical Field

[0001] This utility model relates to the field of spiral tube processing, and in particular to a positioning fixture for spiral tube processing. Background Technology

[0002] Spiral pipe, also known as spiral steel pipe or spiral welded pipe, is made by rolling low-carbon structural steel or low-alloy structural steel strip into a pipe blank at a certain spiral angle (called the forming angle), and then welding the pipe seam together. It can produce large-diameter steel pipes from narrower steel strips.

[0003] A search revealed Chinese Patent Publication No. CN214869949U, which discloses a positioning fixture for threaded steel pipe processing. The fixture includes a functional box; a rotating disk rotatably mounted on the top of the functional box; a rotating shaft rotatably mounted on the top and bottom inner walls of the functional box, with its top end extending above the functional box and fixedly connected to the bottom of the rotating disk; a limiting disk fixedly mounted on the rotating shaft and located inside the functional box; limiting posts fixedly mounted on the top and bottom inner walls of the functional box; two clamping plates slidably mounted on the limiting posts; and two limiting rods fixedly mounted on one side inner wall of the functional box. This utility model provides a positioning fixture for threaded steel pipe processing with the advantages of convenient operation and effectively improving the processing efficiency of threaded steel pipes.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] Reference Figure 1-3This utility model provides an embodiment of a positioning fixture for processing spiral tubes, comprising a base 1, a rotating disk 2 rotatably connected to the surface of the base 1, a first support 3 mounted on one end of the rotating disk 2, a rotating shaft 6 rotatably connected to the inside of the top of the first support 3, a connecting rod 601 connected to one end of the rotating shaft 6 located inside the first support 3, and a positioning block 7 connected to the other end of the connecting rod 601. Four sets of bottom rods 702 are mounted on the circumferential surface of the positioning block 7, and lifting rods 701 are slidably connected inside the four sets of bottom rods 702. A rubber pad 703 is connected to the top of the lifting rod 701. Through the coordinated use of the positioning block 7, lifting rods 701, bottom rods 702, and rubber pad 703, the spiral tube can be fixed from the inside, preventing the spiral tube from shaking during processing and facilitating the processing of the spiral tube surface. The rotating shaft 6 can drive the connecting rod 601 and the positioning block 7 to rotate, thereby allowing the spiral tube to be fixed in place. The spiral tube can rotate, facilitating surface processing. A lead screw 602 is rotatably connected to the inner side of the positioning block 7, and a drive assembly is slidably connected to the surface of the lead screw 602. One end of the drive assembly is connected to the lifting rod 701. The combined use of the rotating shaft 6, connecting rod 601, lead screw 602, and drive assembly can drive the lifting rod 701 and rubber pad 703 to rise and fall, thereby fixing spiral tubes of different sizes, meeting the needs for fixing spiral tubes of different sizes, and improving the applicability of the equipment. A second support seat 4 is installed on the side of the rotating disk 2 away from the first support seat 3. A mounting seat 5 is installed on the top of the second support seat 4, and two sets of limiting clamps 8 are slidably connected to the surface of the mounting seat 5. The second support seat 4, mounting seat 5, and two sets of limiting clamps 8 can clamp and limit the other end of the spiral tube, preventing shaking during processing and improving the stability of spiral tube processing.

[0030] Reference Figure 2The driving assembly includes a sliding seat 604, which is slidably connected to the surface of the lead screw 602. A connecting seat 608 is mounted on the surface of the sliding seat 604. A support rod 607 is rotatably connected inside the connecting seat 608. The other end of the support rod 607 is rotatably connected to one side of the lifting rod 701. The rotation of the lead screw 602 drives the sliding seat 604 to slide. After the sliding seat 604 slides, the connecting seat 608 causes both ends of the support rod 607 to move. The other end of the support rod 607 can then push the lifting rod 701 to rise or fall, causing the top of the rubber pad 703 to contact the inner wall of the spiral tube, thus fixing and limiting the spiral tube from the inside. A first groove 603 is formed on the surface of the lead screw 602, and a groove is formed on one side of the bottom rod 702. The second slide groove 704, the first slide groove 603, and the second slide groove 704 match the support rod 607 and the connecting seat 608. Through the action of the first slide groove 603 and the second slide groove 704, the movement of the support rod 607 and the connecting seat 608 can be guaranteed, thus achieving the effect of fixing the spiral tube. The other end of the lead screw 602 extends to the outside of the first support seat 3 and is connected to the second knob 605 and is rotatably connected to the inside of the rotating shaft 6. The end of the rotating shaft 6 located outside the first support seat 3 is connected to the third knob 606. By rotating the second knob 605, the lead screw 602 can be driven to rotate, which is convenient for the staff to fix the spiral tube. By rotating the third knob 606, the connecting rod 601 and the positioning block 7 can be driven to rotate, which is convenient for rotating the spiral tube.

[0031] Reference Figure 3 The mounting base 5 has a movable groove on its surface. A bidirectional screw 502 is rotatably connected inside the movable groove. Two sets of sliders 501 are slidably connected to the surface of the bidirectional screw 502. The tops of the two sets of sliders 501 are connected to two sets of limiting clamps 8. The rotation of the bidirectional screw 502 can drive the two sets of sliders 501 to move relative to each other. When the sliders 501 move, they can drive the two sets of limiting clamps 8 to move, so that the two sets of limiting clamps 8 clamp and limit the other end of the spiral tube, preventing the spiral tube from shaking during processing. One end of the bidirectional screw 502 extends to the outside of the mounting base 5 and is connected to a first knob 503. Multiple sets of rollers 801 are rotatably connected inside the two sets of limiting clamps 8. Rotating the first knob 503 can drive the bidirectional screw 502 to rotate, which is convenient for the operator to clamp the spiral tube. The multiple sets of rollers 801 can improve the clamping effect of the spiral tube and facilitate the rotation of the spiral tube.

[0032] Reference Figure 4The base 1 has a rotating seat 9 rotatably connected inside. The top of the rotating seat 9 is connected to the rotating disk 2. The rotating seat 9 has multiple sets of limiting holes 901 inside. Two sets of matching positioning rods 902 are slidably connected to both sides of the base 1. The base 1 has a telescopic groove 904 inside. A limiting plate 905 is installed on the surface of the positioning rod 902 inside the telescopic groove 904. A spring 903 is installed on one side of the limiting plate 905. Pull rings 906 are rotatably connected to the two sets of positioning rods 902 on the outer surface of the base 1. The rotating disk 2 can be rotated by the rotating seat 9, which makes it easy to adjust the angle of the spiral tube in the horizontal position. After the adjustment is completed, the positioning rod 902 is inserted into the limiting hole 901 to fix the position of the rotating seat 9. Pulling the pull ring 906 to remove the positioning rod 902 from the limiting hole 901 cancels the fixing effect on the rotating seat 9. The cooperation of the spring 903 and the limiting plate 905 can improve the fixing effect on the rotating seat 9, so that one end of the positioning rod 902 is always inserted into the limiting hole 901.

[0033] Working principle: In use, first place one end of the spiral tube into the surface of the mounting base 5, then slowly push the spiral tube to move it, so that the positioning block 7 is inserted into the interior of the spiral tube. Then, turn the second knob 605 to drive the lead screw 602 to rotate. After the lead screw 602 rotates, it drives the sliding seat 604, the support rod 607 and the connecting seat 608 to move. The support rod 607 can then push the lifting rod 701 to rise and fall, so that the rubber pad 703 is tightly attached to the inner wall of the spiral tube. After one end of the spiral tube is fixed, turn the first knob 503 to drive the two sets of limiting clamps 8 to move, so that the rollers 801 inside the two sets of limiting clamps 8 are tightly attached to the outer wall of the spiral tube, thereby completing the fixed clamping of the spiral tube and improving the stability of the spiral tube fixation.

[0034] 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.
