Description

Technical Field

[0001] This utility model relates to the field of pipe welding technology, specifically a quick assembly fixture for pipe welding. Background Technology

[0002] Pipe fittings are a general term for components in a piping system that serve functions such as connection, control, direction change, flow diversion, sealing, and support. Pipe materials are the materials used to make pipe fittings.

[0003] Existing pipe welding fixtures only support a single pipe type and cannot clamp and fix round or square pipes. Changing fixture modules will increase downtime and is not conducive to rapid welding between pipes. Therefore, in order to reduce unnecessary fixture changes and increase the clamping of round and square pipes, we designed a quick assembly fixture for pipe welding. Through rapid operation, it can achieve precise positioning and fixing of pipes, thereby improving the welding efficiency of pipes. Utility Model Content

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.

[0026] Please see Figure 1-6 This utility model provides a technical solution: a quick assembly fixture for pipe welding, including a working platform 1, on which a sliding groove 2 is provided. The working platform 1 has four sliding grooves 2. The first and second sliding grooves are horizontally placed. The second and third sliding grooves are connected and are arc-shaped.

By setting multiple sliding grooves, it is convenient for the mechanism inside the groove to move within the groove and adjust the orientation of the mechanism.

A positioning spring pin 23 is provided on the side of the cylinder 21. The positioning spring pin 23 is composed of a spring, a pin, and a positioning sleeve. One end of the spring and the pin are located in the positioning sleeve. Eight semi-circular grooves adapted to the end face of the pin are equally spaced on the inner circumference of the convex groove. One end of the pin passes through the cylinder 21 and extends into the semi-circular groove. By setting the cylinder 21 and the limiting disk 22, it is easy to prevent the turntable 4 from falling off the slider 3 without affecting the rotation of the turntable 4. By setting the positioning mechanism in the slider 3, it is easy to make the top mechanism of the turntable 4 have the effect of rotation angle and fixation.

[0030] A concave plate 5 is fixedly connected to the turntable 4. There are two sliders 3 and two concave plates 5. Two right-angle plates 6 are provided in each of the two concave plates 5. Several right-angle grooves are opened horizontally on the upper and lower edges of the two right-angle plates 6. By setting two right-angle plates 6 that move relative to or towards each other in the concave plate 5, it is easy to hold the round tube. At the same time, by setting right-angle grooves in the right-angle plates 6, it is also easy to fix the square tube, so as to facilitate subsequent welding of the pipe.

[0031] Furthermore, a right-angled plate 6 is provided inside the concave plate 5. Multiple slots 7 are provided on both right-angled sides of the right-angled plate 6. The multiple slots 7 are equidistantly distributed on the two right-angled sides of the right-angled plate 6. A support plate 8 is fixedly connected to the outer right angle of the right-angled plate 6. A movable sleeve 9 is fixedly connected to the bottom of the support plate 8. A bidirectional screw 10 is threadedly connected to the movable sleeve 9. Both ends of the bidirectional screw 10 are threadedly connected to the movable sleeve 9, and a support plate 8 is fixed on both movable sleeves 9. Movable grooves that move relative to the support plate 8 and movable sleeve 9 are respectively provided inside the concave plate 5. By providing two movable sleeves 9 at both ends of the bidirectional screw 10, it is convenient for the bidirectional screw 10 to drive the two movable sleeves 9 to move relative to each other when rotating, so as to provide power to the support plate 8 at the top of the movable sleeve 9.

[0032] A vertical bevel gear 11 is fixedly connected to the end face of the bidirectional screw 10, and a horizontal bevel gear 12 meshes with the vertical bevel gear 11. A forward and reverse motor 13 is fixedly connected to the horizontal bevel gear 12. A protective cover 24 is provided on the surface of the vertical bevel gear 11 and the horizontal bevel gear 12, and the protective cover 24 is fixedly connected to the concave plate 5. The protective cover 24 has a hole that matches the output shaft of the forward and reverse motor 13, and the forward and reverse motor 13 is fixedly connected to the concave plate 5. By providing the protective cover 24, it is convenient to protect the horizontal bevel gear 12 and the vertical bevel gear 11.

[0033] Furthermore, a positioning ring 25 is fixedly connected to the surface of the bidirectional screw 10, and a circular hole adapted to the end face of the bidirectional screw 10 is opened at the bottom of the concave plate 5, and a positioning groove adapted to the positioning ring 25 is opened on the inner wall of the circular hole. By setting the positioning ring 25 on the surface of the bidirectional screw 10, it is convenient to limit the bidirectional screw 10, while not affecting the rotation of the bidirectional screw 10.

[0034] In this embodiment, the working platform 1, concave plate 5, and right-angle plate 6 facilitate the positioning of the pipe. Simultaneously, the bidirectional screw 10, movable sleeve 9, and support plate 8 inside the concave plate 5 facilitate the relative or opposite movement of the two right-angle plates 6, allowing them to interlock and fix the pipe, thus facilitating subsequent welding of its ends. The slider 3 and positioning mechanism at the bottom of the concave plate 5 allow it to move on the working platform 1, while also providing rotation and positioning. The locking mechanism at the bottom of the slider 3 allows it to be lifted and fixed after movement, enabling the fixture to quickly fix the pipe and facilitate welding.

[0035] Working principle: In use, first determine whether the two pipes are to be welded horizontally (port to port) or vertically (port to pipe wall). When the two pipes are to be welded horizontally, simply move the two concave plates 5 relative to each other. When the two concave plates 5 are moved to the closest relative position, rotate the threaded rod 19 in the locking mechanism to rotate and push the right-angle trapezoidal plate 17, and lift the top plate 14 so that the top plate 14 presses against the slider 3 and fixes the slider 3. Then place the two pipes in the concave plates 5 on both sides so that the ports of the two pipes are close together. Then start the forward and reverse motor 13 so that it drives the bidirectional screw 19 to rotate through the bevel gear. In turn, the bidirectional screw 19 drives the support plate 8 and the right-angle plate 6 to move relative to each other through the movable sleeve 9. The relative movement of the two right-angle plates 6 in the concave plates 5 limits and fixes the pipes, which is convenient for subsequent welding.

[0036] When two pipes need to be welded vertically, simply move the slider 3 on the other side so that it passes through the arc-shaped groove 2 and is perpendicular to the horizontal slider 3, and then weld the pipes according to the steps for horizontal welding. In this way, the fixture can not only weld horizontally but also vertically. At the same time, by rotating the positioning mechanism at the bottom of the concave plate 5, the angle between the two pipes can be adjusted to form multi-angle welding and increase the effect of multi-angle welding of pipes.

[0037] The mechanisms, components, and parts in this utility model that are not specifically described are all existing structures that already exist in the prior art and can be purchased directly from the market.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
