Welding fixture with adjustable welding angle

Technical Field

The utility model belongs to the technical field of welding fixtures, and in particular relates to a welding fixture capable of adjusting the welding angle.

Background technique

In daily welding processing, it is difficult to achieve consistent accuracy for traditional welding processing of pipes and rods.

After the initial spot welding is completed, multiple corrections are required before reinforcement can be carried out. The welding process is cumbersome, labor-intensive, time-consuming and labor-intensive, which seriously delays work efficiency. In the field of welding technology, many welding workpieces have angle requirements. During welding, the angles of different welding workpieces are inconsistent, and are limited by space and welding methods. The angle adjustment range is small and difficult to control, the welding accuracy cannot be guaranteed, and the work intensity is high. Therefore, it is necessary to make improvements to the above problems.

The angle adjustment range is large and manual adjustment and fixing by the staff is not required, thereby greatly reducing the labor intensity, improving the welding accuracy and consistency, meeting the welding locking requirements of two weldings with different cross-sectional sizes, and having high use value.

The technical solution adopted by the utility model is as follows: a welding fixture with adjustable welding angle, comprising a fixed seat, two concentrically arranged circular rings I and II fixedly connected to the fixed seat, and a movable seat fixedly connected to the circular rings I and II in an adjustably positionable manner, the supporting surfaces of the fixed seat and the movable seat are tangent to the circular rings I and II, and two welding parts are respectively placed on the supporting surfaces of the fixed seat and the movable seat, and locking and fixing devices for respectively locking and fixing the two welding parts are provided on the supporting surfaces of the fixed seat and the movable seat, and the adjustment of the welding angle of the two welding parts is achieved by adjusting the angle between the supporting surface of the movable seat and the supporting surface of the fixed seat.

Among them, the locking and fixing device includes an L-shaped plate and a handwheel bolt, the vertical plate of the L-shaped plate is perpendicular to and fixedly connected to the supporting surface, and the handwheel bolt is threadedly connected to the horizontal plate of the L-shaped plate, and the weldment is pressed and fixed by the pressure plate fixed to the end of the handwheel bolt by rotating the handwheel bolt.

A welding fixture with adjustable welding angle, as shown in Fig. 1-3, comprises a fixed seat 3, two circular rings Ⅰ1 and Ⅱ2 which are concentrically arranged and fixedly connected to the fixed seat 3, and a movable seat 4 which is position-adjustably fixedly connected to the circular rings Ⅰ1 and Ⅱ2, the support surfaces of the fixed seat 3 and the movable seat 4 are tangent to the circular rings Ⅰ1 and Ⅱ2, and two welding parts 5 are respectively placed on the support surfaces of the fixed seat 3 and the movable seat 4, the support surfaces of the fixed seat 3 and the movable seat 4 are provided with locking and fixing devices 8 for locking and fixing the two welding parts 5 respectively, and the welding angle of the two welding parts 5 is adjusted by adjusting the angle between the support surface of the movable seat 4 and the support surface of the fixed seat 3; in the above structure, the locking and fixing device 8 is provided on the fixed seat 3 which is fixedly connected to the two circular rings Ⅰ1 and Ⅱ2 which are concentrically arranged at intervals, and the movable seat 4 which is position-adjustably fixedly connected, so as to lock and fix the welding parts 5 located on the support surfaces of the fixed seat 3 and the movable seat 4, thereby solving the defects of the traditional welding method, such as high labor intensity, low welding efficiency, small angle adjustment range and inconvenient control;

The specific structure of the locking and fixing device 8 is as follows: the locking and fixing device 8 includes an L-shaped plate 8-1 and a handwheel bolt 8-2, the vertical plate of the L-shaped plate 8-1 is perpendicular to and fixed to the supporting surface, and the handwheel bolt 8-2 is threadedly connected to the horizontal plate of the L-shaped plate 8-1, and the welding piece 5 is pressed and fixed by the pressing plate 8-3 fixed to the end of the handwheel bolt 8-2 by rotating the handwheel bolt 8-2; in the above structure, by arranging the locking and fixing device 8 on the supporting surfaces of the movable seat 4 and the fixed seat 3, the welding piece 5 placed on the supporting surface is quickly clamped and fixed, without manual clamping and fixing, freeing the hands of the staff and simplifying the angle adjustment process;

Among them, the movable seat 4 and the ring Ⅰ1 and the ring Ⅱ2 have an adjustable fixed connection structure as follows: a screw 6 extending into the gap between the ring Ⅰ1 and the ring Ⅱ2 is welded and fixed at the inner corner of the movable seat 4, and the inner sides of the rings Ⅰ1 and Ⅱ2 are provided with a locking nut 7 which is threadedly fixed to the screw 6 and has an outer contour size larger than the distance between the rings Ⅰ1 and Ⅱ2. The welding angle of the two welded parts 5 is adjusted by loosening the locking nut 7 and moving the movable seat 4; specifically, the movable seat 4 and the fixed seat 3 are both made of angle iron ; Specifically, the circular rings Ⅰ1 and Ⅱ2 are provided with angle engraved lines for displaying the spatial angle between the movable seat 4 and the support surface of the fixed seat 3; in the above structure, a bolt 6 fixed to the inner corner position of the movable seat 4 and a locking nut 7 having an outer contour size larger than the spacing distance between the circular rings Ⅰ1 and Ⅱ2 are used. By moving the movable seat 4 to a suitable position along the distance between the circular rings Ⅰ1 and Ⅱ2 and tightening the locking nut 7, the spatial angle between the movable seat 4 and the support surface of the fixed seat 3 can be quickly adjusted, which is convenient and fast, saving time and effort;

At this time, the bolt 6 slides in the gap between the ring Ⅰ1 and the ring Ⅱ2. After the movable seat 4 moves to the space angle between the supporting surface of the fixed seat 3 and the welding angle of the two welding parts 5, tighten the locking nut 7, and then rotate the handwheel bolt 8-2 on the movable seat 4 to move the pressure plate 8-3 upward, place another welding part 5 on the supporting surface of the movable seat 4, and adjust the other welding part 5, so that the joint ends of the two welding parts 5 are at the welding position, tighten the handwheel bolt 8-2 to press and fix the other welding part 5, and re-check and determine the angle between the two welding parts 5. When the re-checked angle is the same as the welding angle, welding can be performed. Otherwise, the movable seat 4 is adjusted to the welding angle by the locking nut 7, and then welding is completed.

When the present technical solution is in use, the movable seat 4 can also be moved to a symmetrical position with the fixed seat 3, that is, the supporting surfaces of the movable seat 4 and the fixed seat 3 are located on the same plane. In this way, when the ends of the two welding parts 5 are butt-welded, they can be automatically aligned to achieve the two welding parts 5 being fixedly connected into a straight line.
