It can be understood that when in processing, the steel plates 7 of the two pin joint joints need to be clamped and fixed according to the specified distance and then processed in the next step, so that the defect rate of the pin joint caused by the movement of the steel plates in the processing process is avoided. In this example, two steel plates 7 of the pin joint are respectively clamped between the vertical plate 2 and one group of positioning assemblies 3, and the vertical plate 2 and the positioning assemblies 3 are used for clamping the steel plates 7 more tightly through the adjusting mechanism 4.
It should be noted that the spacing distance between the two sets of positioning assemblies 3 is the spacing distance between the two steel plates 7 of the pin joint to be processed.
In some alternative embodiments, each set of the positioning assemblies 3 includes two stiffening plates 31, and planes formed by the two stiffening plates 31 of each set of the positioning assemblies 3 near one side of the vertical plate 2 are parallel to each other.
It can be understood that the two stiffening plates 31 and the vertical plate 2 of each set of positioning assembly 3 clamp the steel plate 7, and therefore the planes formed by the two stiffening plates 31 of each set of positioning assembly 3 near one side of the vertical plate 2 need to be parallel to each other, so as to ensure that the two clamped steel plates 7 are kept in a parallel state when clamped.
In this example, the two stiffening plates 31 of each set of positioning elements 3 are parallel to each other and perpendicular to the base plate 1.
In some alternative embodiments, as shown in fig. 3, two of the stiffening plates 31 of each set of the positioning assembly 3 are provided with a top plate 5 near one end of the vertical plate 2, and the two top plates 5 are parallel to each other.

Further, the adjusting mechanism 4 is a telescopic member, and is disposed between the two vertical plates 2, and two ends of the telescopic member are respectively connected to the two vertical plates 2.
It can be understood that guiding mechanism 4 can be telescopic link etc. and when the extensible member extended to both ends, two risers 2 were held by the extensible member top, moved to the direction of keeping away from each other along the spout, until with locating component 3 with steel sheet 7 centre gripping.
In some optional embodiments, the adjusting mechanism 4 is a bolt, which is screwed to any one of the vertical plates 2, and the bolt is rotated to push one end of the bolt toward the other vertical plate 2.
During specific operation, place two steel sheets 7 of treating processing respectively between locating component 3 and riser 2, then the rotating bolt, make the one end of connecting the bolt on a riser 2 push up to another riser 2, until with another riser 2 contact, continue the rotating bolt, start being held the removal by the top with the less one of bottom plate 1 frictional force in two risers 2 this moment, until with locating component 3 together with steel sheet 7 centre gripping, then continue the rotating bolt until another riser 2 also remove towards the direction of locating component 3 of its one side, with another steel sheet 7 also centre gripping, the fixing of two steel sheets has been accomplished promptly, and guaranteed that the distance between two steel sheets is the distance that processing required.
In this example, an M20 bolt is used, and the length of the bolt should be greater than the separation distance between the two sets of positioning assemblies 3.
Furthermore, the number of the bolts is two, and the two bolts are respectively in threaded connection with positions close to the two ends of the vertical plate 2.
It should be noted that the position of the bolt should be specifically set according to the shape of the pin joint steel plate to be processed, provided that the interference influence on the steel plate is not caused in the process of rotating the bolt; in this example, two bolts are arranged and respectively connected to two ends of the vertical plate 2, so that when the bolts are used for supporting the steel plate 7, two ends of the steel plate 7 are supported together, and the stress is more balanced.
In some optional embodiments, one of the vertical plates 2 is fixedly connected to one of the positioning plates 6 near the side wall of the other vertical plate 2, and the positioning plate 6 is near the end of the vertical plate 2 connected to the positioning plate.
Further, the positioning plate 6 is perpendicular to the vertical plate 2 and parallel to the bottom plate 1, so as to better position the vertical plate 8 to be welded.
According to the processing requirement, as shown in fig. 5, a vertical plate 8 needs to be welded on the opposite side walls of the two steel plates 7 of the pin joint, one end of the vertical plate 8 is connected with one of the steel plates 7, and the other end of the vertical plate extends to the other steel plate 7 at a certain distance, so that a positioning plate 6 is fixedly connected to the side wall of one of the vertical plates 2 close to the other vertical plate 2, and the positioning plate 6 is close to the end of the vertical plate 2 connected with the positioning plate 6.
When the steel plate welding fixture is used for machining, a vertical plate 8 to be welded is placed on the positioning plate 6, one end of the vertical plate 8 extends out of the positioning plate 6, the extending portion of the vertical plate 8 is welded with the steel plate 7 in advance, and the vertical plate 8 continues to be welded after the steel plate 7 is taken out of the fixture, so that the steel plate 7 is completely connected with the steel plate 8.
It can be understood that in the welding process, because the spacing distance between the positioning plate 6 and the vertical plate 2 which is not connected with the positioning plate is the spacing distance between the vertical plate 8 and the steel plate 7 which is not connected with the vertical plate, the positioning plate 6 can position the welding position of the vertical plate 8; and meanwhile, the vertical plate 8 to be welded is placed on the positioning plate 6, and the positioning plate also plays a role in supporting the vertical plate 8, so that the welding stability and accuracy are improved.
It will be appreciated that for ease of manufacture, the vertical height of the riser 2 should be less than the vertical height of the steel plate 7 and the lateral length of the riser 2 should be less than the lateral length of the steel plate 7.
