The central screw and the positioning guide rod are fixedly arranged on the fixed bottom plate and are vertical to the fixed bottom plate; the center of the upper movable plate is provided with a central screw rod through hole, the position corresponding to the positioning guide rod is provided with a through hole, and the central screw rod and the positioning guide rod penetrate through the corresponding through holes; the upper movable plate can move up and down along the central screw rod and the positioning guide rod and is kept parallel to the fixed bottom plate; two nuts are arranged on the central screw rod and are respectively positioned above and below the upper movable plate block for clamping and fixing the upper movable plate block. Because the small-size stand truss structure fixes a position the difficulty when the welding, so design this device assistance-localization real-time, make each pole setting keep vertical and along horizontal ring evenly distributed in welding process, realize welded accurate shaping.
Description
Technical Field
The utility model relates to the field of welding tool fixtures, in particular to a welding and positioning device for a vertical rod of a small-sized upright truss.
Background
In the process of welding the small-sized upright column truss structure, the vertical state of the upright rods and the uniform distribution among the rod pieces are difficult to ensure. Currently, common positioning technologies such as gluing, wire binding and the like are known, but the conventional measures are inconvenient to operate and are not beneficial to the implementation of the welding process, the welding effect can be adversely affected by adopting a bonding method, and a simple, portable and reusable auxiliary welding positioning device is absent at present.
Disclosure of Invention
Aiming at the problems, the utility model designs a welding and positioning device for upright rods of a small-sized upright truss.
The utility model designs a welding and positioning device for upright rods of a small upright truss, which comprises a fixed bottom plate 1, an upper movable plate 2, a central screw rod 3, a positioning guide rod 4 and a nut 5. The central screw rod 3 and the positioning guide rods 4 are fixedly arranged on the fixed base plate 1 and are perpendicular to the fixed base plate 1, the two positioning guide rods 4 are respectively distributed on two sides of the central screw rod 3, and the distance between the central screw rod 3 and the positioning guide rods 4 is smaller than the radius of the circumference where the truss upright post is located. Through holes matched with the number of the upright rods and the diameters of the upright rods are uniformly distributed on the circumference of the fixed bottom plate 1, which is centered on the central screw rod 3, and the center of the truss upright column; the upper movable plate 2 is a circular plate or a regular polygon plate with the diameter equal to the diameter of the circumference of the center of the truss upright post, the number of edges is equal to the number of truss upright posts, the center is provided with a through hole corresponding to the central screw rod 3, the position of the positioning guide rod 4 is also provided with a through hole corresponding to the positioning guide rod, and the position corresponding to the round hole of the fixed bottom plate is provided with a semicircular hole; the central screw 3 and the positioning guide rods 4 penetrate through corresponding through holes, the upper movable plate 2 can move up and down along the central screw 3 and the positioning guide rods 4, and the upper movable plate 2 and the fixed bottom plate 1 can be kept parallel through the two positioning guide rods 4; the upper part and the lower part of the upper movable plate on the central screw rod are respectively provided with a nut which is used for fixing the position of the upper movable plate 2. The truss vertical rods are assembled in the through holes of the fixed bottom plate 1 and the semicircular holes of the upper movable plate 2, so that the vertical rods can be fixed.
The utility model has the beneficial effects that: the difficult problem of pole setting location among the small-size stand truss structure welding process is solved, for the welding of small-size stand truss provide simple and convenient, quick detachable pole setting assistance-localization real-time device, ensure going on smoothly of welding process.

Detailed Description
In order to explain the technical features of the present solution, the present solution is described below by a specific embodiment and with reference to the accompanying drawings.
Each part of the device is assembled according to a drawing 1, and assuming that 6 vertical rods need to be welded on a truss, a fixed bottom plate 1 and an upper movable plate 2 are punched, 6 through holes are processed on the circumference of the center of a truss upright column on the fixed bottom plate 1 by taking a central screw rod 3 as a center, the diameter of each through hole is equal to that of each vertical rod, and 6 semicircular holes are processed on the circumference of the upper movable plate 2 corresponding to the through holes of the fixed bottom plate 1. During assembly, the central screw 3 and the positioning guide rod 4 are fixedly arranged on the fixed bottom plate 1 and are vertical to the fixed bottom plate 1, the upper movable plate 2 is connected with the central screw 3 and the positioning guide rod 4 through corresponding through holes, and nuts 5 are respectively arranged on the central screw 3 and above and below the upper movable plate 2 and used for fixing the position of the upper movable plate 2. After the assembly is finished, the vertical rods are placed in the through holes of the fixed bottom plate 1 and the semicircular holes of the upper movable plate 2, so that the rod pieces can be vertically and uniformly distributed; and sleeving the upper ring and the lower ring into the vertical rod, firstly welding the top ring, fixing the vertical rod after welding, taking out the positioning device from the lower end, and then welding the bottom ring.
