Abstract

The utility model discloses a frame welding mould, which comprises a base. Two supports which are arranged in parallel are fixedly connected onto the base, at least two supporting blocks are arranged on each support at intervals, supports are rotationally mounted above the supporting blocks, a carrier roller shaft is connected between each two opposite supports, each support is provided with a step surface extending to the end surface of the support, the ends of the supports are connected with compression devices which are compression bolts screwed on the end surfaces of the supports, and a pressing handle is disposed at an outward extending end of each compression bolt. Two opposite borders of a rolling machine frame after being cut are placed on the step surfaces, and two other opposite borders are placed on the supports, thereby completing welding of the borders. Accordingly, the frame welding mould can realize correct and fast positioning, guarantees uniformity of sizes of a plurality of frames, reduces or eliminates welding deformation, leads welding joints to be located at fine operation positions, increases welding precision and interchangeability of the rolling machine frame, improves production efficiency, and is convenient for fast assembly and correction.

Description

The framework welding positioner

Technical field

The utility model relates to a kind of processing tool that rolls, and specifically is a kind of framework welding positioner that rolls bed frame that is used to process.

Background technology

Existingly roll framework, roller group, drive disk assembly, motor reducer, the supporting leg that bed is made up of U type or Z-shape steel and form.The critical piece that rolls bed is a framework, for guaranteeing the stability of roller group and drive disk assembly, the depth of parallelism of framework and perpendicularity need higher required precision, when making framework now, U type or Z-shape steel be tiled in carry out assembly welding on the flat board, because the restriction of dull and stereotyped flatness is grown and be subjected to the length of U type or Z-shape steel, thereby can not guarantee the required precision of weldment and high interchangeability, bring certain difficulty and uncertainty to the later stage assembling, and carry out sizing by manually-operated entirely, be difficult to guarantee the uniformity of a plurality of frame sizes.

The utility model content

The technical problems to be solved in the utility model provides a kind of framework welding positioner that rolls bed frame that is used to make.

For solving the problems of the technologies described above, the framework welding positioner that is provided comprises base, its design feature is: be connected with two supports that be arranged in parallel on the base, be interval with at least two trays on each support, the top of tray is rotatablely equipped with bearing, be connected with roller carrier shaft between the two relative bearings, bearing is provided with the step surface that extends its end face.

After adopting said structure, the two relative edge's frames that roll in the bed frame after the cutting are placed on the step surface, two relative edge's frames are placed on the support in addition, thereby finish welding to frame, thereby this welding positioner can be correctly, location apace, guaranteed the uniformity of a plurality of frame sizes, reduce or eliminate welding deformation, make weld seam be in good operating position (being generally downhand welding), improved operator's labour intensity, be more conducive to obtain good welding quality, improved the welding precision and the interchangeability of rolling bed frame, improved production efficiency, be convenient to assembling fast and proofread and correct.

As improvement of the present utility model, the end of described bearing is connected with hold down gag, after frame is placed on the step surface, can frame be compressed by hold down gag, thereby make its not redeformation.

Described hold down gag is the hold-down bolt that is screwed onto on the bearing end face, and the overhanging end of hold-down bolt is provided with and compresses handle.

Described support is provided with the arrangement for adjusting height of regulating the tray height, can adjust the height of tray, thereby adjusts the height of step surface, makes each step surface on same horizontal plane, so that guarantee the horizontal size of framework.

Described arrangement for adjusting height is the adjustment bolt that is screwed onto on the support, and described tray is overlapped on the top of adjusting bolt.

As further improvement of the utility model, be arranged with stopper slot on the described roller carrier shaft, also the frame of framework can be placed in the stopper slot, thereby the framework that the utility model can carry out a plurality of sizes welds.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a structural representation of the present utility model;

The schematic diagram of Fig. 2 for analysing and observe along the A-A line among Fig. 1.

The specific embodiment

Framework welding positioner as depicted in figs. 1 and 2, it comprises the base of being made by flat board 1, be connected with two supports that be arranged in parallel 2 on the base 1, support 2 can by stability preferably I-steel make, be interval with at least two trays 5 on each support 2, tray 5 is V-shape, the top of tray 5 is rotatablely equipped with bearing 6, be connected with roller carrier shaft 3 between the two relative bearings 6, be arranged with stopper slot 8 on the roller carrier shaft 3, frame can be placed in the stopper slot 8 and weld.Bearing 6 is provided with the step surface 7 that extends its end face, step surface 7 be machined on the bearing 6 in the disc that contracts, the end of bearing 6 is connected with hold down gag, this hold down gag is the hold-down bolt 4 that is screwed onto on bearing 6 end faces, after frame is placed on the step surface 7, the overhanging end of hold-down bolt 4 is provided with and compresses handle 10, compresses handle 10 and cooperates with step surface 7 end faces on the bearing 6 frame is compressed.Above-mentioned support 2 is provided with the arrangement for adjusting height of regulating tray 5 height, and this arrangement for adjusting height is the adjustment bolt 9 that is screwed onto on the support 2, and tray 5 is overlapped on the top of adjusting bolt 9.

The utility model not only can be used for rolling the welding fabrication of bed frame, can also carry out welding fabrication to the framework of other plane conveying equipments.
