Description

Technical Field

[0001] The utility model relates to the technical field of pipe beam assembly welding, and more specifically, to a horizontal screen pipe beam assembly welding fixture structure. Background Art

[0002] The horizontal screen is a vibrating screen with an elliptical motion trajectory. It is suitable for screening solvents and cold sintered ores in the metallurgical industry, ore grading in the mining industry, grading and dehydration and de-mediuming in the coal industry. It is widely used in quarries and screening of sand and gravel materials. It can also be used for grading products in coal preparation, ore dressing, building materials, construction, power and chemical industries. Due to the harsh operating environment of the horizontal screen, it is necessary to achieve high efficiency, high screening accuracy, large processing capacity, and a wide range of applications. This puts higher requirements on the strength and manufacturing accuracy of the horizontal screen. The pipe beam assembly weldment is the main component connecting the side plates on both sides of the horizontal screen. Its welding accuracy and quality directly affect the strength and accuracy of the entire horizontal screen after assembly.

[0003] At present, the welding process of pipe beam assembly weldments adopts cutting, welding (marking and assembly welding is adopted during welding), and then processing the flange mounting holes and the flange mounting surfaces on both sides, so as to ensure the coaxiality of the flange mounting holes at both ends and the consistency of the length size of multiple pipe beam assembly weldments. Although such processing can well ensure the coaxiality of the flange mounting holes at both ends and the consistency of the length size of multiple pipe beam assembly weldments, this processing is time-consuming and labor-intensive, the labor intensity of the processing personnel is high, the production cycle is long, the productivity is low, it is not suitable for mass production, and the product welding deformation is large. Therefore, it is necessary to provide a new welding fixture that can not only ensure the coaxiality of the flange mounting holes at both ends of the pipe beam and the consistency of the length size of multiple pipe beam assembly weldments, but also solve and avoid the above shortcomings.

[0027] Working principle: The utility model designs a horizontal screen pipe beam group welding fixture structure. The two rollers 2 in the base component 1 are equipped with rolling bearings. The two rollers 2 can rotate relative to the base component 1. The welding fixture main component (refer to the attached manual) Figure 3 ) The positioning plates 5 at both ends are respectively placed in the roller grooves of the two base components 1, and the welding tool main body component is rotated. The welding tool main body component can be flexibly rotated with the rollers 2 on the two rollers 2 of the base component 1, which is convenient for rotation during welding. The positioning plates 5 at both ends of the welding tool main body are connected and positioned by four positioning rods 6, and are locked by the locking nuts 3 at both ends;

[0028] Among them, the pipe beam assembly weldment (refer to the attached manual Figure 2) The two flanges 9 are respectively installed on the positioning plate 5 by the positioning bolts and nuts 4, so that the flange 9 is positioned and clamped on the positioning plate 5. The three positioning rods 6 connect the positioning plates 5 at both ends (the notches 501 of the positioning plates at both ends are in the same direction) and are locked by nuts. Steps are processed at both ends of the three positioning rods 6. The distances between the step ends at both ends of the three positioning rods 6 are equal, so that the positioning of the two positioning plates 5 on the three positioning rods 6 is achieved, and the coaxiality of the holes in the same direction on the flange plates at both ends is ensured, and the distance between the flanges 9 at both ends is also ensured. Then, the steel pipe cross beam 7 in the pipe beam assembly weldment is installed from the direction of the notch 501 of the positioning plate to the middle hole of the flanges 9 at both ends. Then, the fourth positioning rod 6 is installed in the notches 501 of the positioning plates at both ends, and it is locked from both ends with nuts. The two end surfaces of the steel pipe cross beam 7 are adjusted. To the distance of the outer end faces of the flanges 9 at both ends, when the distance is adjusted to be equal, spot-weld the flanges 9 at both ends and the steel pipe cross beam 7 to position them, and then place the outer circles of the positioning plates 5 at both ends of the above-mentioned assembly components in the roller grooves of the two base components 1, and two people at both ends weld the connections between the flanges 9 at both ends of the pipe beam weldment and the steel pipe cross beam 7 at the same time. When welding, it is necessary to rotate, and one person can rotate the above-mentioned assembly component. After the inner and outer welds at the connections between the flanges 9 at both ends of the pipe beam weldment and the steel pipe cross beam 7 are all welded in the circumferential direction, the circumferential ribs 8 of the pipe beam weldment are gradually welded in the middle of the two holes on the end faces of the flanges 9 and on the outer circle of the steel pipe cross beam 7. After the welds at the connections of all parts of the pipe beam assembly are welded, the positioning bolts and nuts 4 in the welding tool body and the locking nuts 3 at both ends of the positioning rod 6 are gradually removed to complete the welding of the pipe beam weldment.
