Description

Technical Field

[0001] The utility model relates to the technical field of H-beam assembly machines, in particular to a tightening and positioning structure of an H-beam assembly machine. Background Art

[0002] With the rapid development of my country's steel structure industry, H-shaped steel used in steel structure workshops is increasingly developing towards fine and efficient types. Generally, H-shaped steel is welded together by two cross plates and one web. Because of its H-shaped shape, it is called H-shaped steel. When processing H-shaped steel on the assembly machine, it is necessary to limit the splicing between the web and the cross plate to ensure the efficient welding process.

[0003] A Chinese patent with announcement number CN212371510U discloses a clamping and positioning device for an H-beam assembly machine, comprising a support base, wherein guide rails are vertically fixedly connected to the upper sides of the left and right ends of the support base, U-shaped cross frames are slidably connected to the upper and lower sides of the guide rails, and a linkage rod is horizontally fixedly connected between the U-shaped cross frames aligned on the left and right sides, and a clamping frame is fixedly connected to the midpoint of the line connecting the guide rails on the left and right sides.

[0004] Although the clamping and positioning device of the H-beam assembly machine described in the above patent can reliably clamp and fix the web and cross plate of the H-beam during welding, the welding position of the cross plate and the web is fixed during the entire clamping and positioning process, and the welding position of the web and cross plate of the H-beam cannot be flexibly adjusted according to actual welding needs. As a result, the H-beam is prone to mismatch between the welding position and the welding head of the welding equipment during the entire welding process, resulting in a relatively low efficiency in the welding and assembly of the H-beam. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The technical problem to be solved by the utility model is to provide a clamping positioning structure of an H-beam assembly machine which is capable of flexibly rotating and displacing the web and vertical plate of the H-beam in a clamping state, ensuring that the welding position and the welding head of the welding equipment can be conveniently matched, thereby accelerating the welding assembly efficiency of the H-beam.

[0007] (II) Technical solution

[0008] The utility model is achieved through the following technical scheme: the utility model proposes a clamping and positioning structure of an H-beam assembly machine, including a support, an adjusting mechanism is installed on the upper end of the support, and the adjusting mechanism includes a two-way electric slide rail four installed in the middle of the upper end of the support, a mounting plate installed on two sliding blocks provided on the two-way electric slide rail four, pulleys symmetrically installed on both sides of the bottom end of the mounting plate, and a slide groove symmetrically opened on the support and cooperating with the pulley, and each of the mounting plates is installed with a rotating clamping mechanism, and the rotating clamping mechanism includes a rotating motor installed in the middle of one side wall of the mounting plate, a rotating plate installed at the power output end of the rotating motor, two two-way electric slide rails three symmetrically installed on the rotating plate facing away from the side wall of the mounting plate, a two-way electric slide rail two installed on two sliding blocks on the same side of the two-way electric slide rail three, a clamping plate two installed on two sliding blocks provided on the two-way electric slide rail two, a two-way electric slide rail one installed in the middle of the rotating plate, a clamping plate one installed on two sliding blocks provided on the two-way electric slide rail one, and balls evenly distributed on the clamping wall of the clamping plate one.

[0009] Furthermore, the support is an inverted U-shaped structure, and an operation panel is also installed on the upper part of one side wall of the support.

[0010] By adopting the above technical solution, the support can ensure the stable placement of the entire positioning mechanism.

[0011] Furthermore, the bidirectional electric slide rail four is embedded in the support and connected with the support bolts, and the mounting plate is connected with two built-in sliding blocks on the bidirectional electric slide rail four by bolts.

[0012] By adopting the above technical solution, the two-way electric slide rail 4 drives the two mounting plates to approach each other, and the web and the cross plate can be initially clamped according to the length of the H-shaped steel.

[0013] Furthermore, the pulley is rotatably connected to the mounting plate, and the pulley contacts the bottom end of the slide groove.

[0014] By adopting the above technical solution, the cooperation between the pulley and the slide groove can ensure stable sliding adjustment of the mounting plate.

[0015] Furthermore, the bidirectional electric slide rail three is symmetrically distributed on the rotating plate in the upper and lower parts, and the bidirectional electric slide rail two is symmetrically distributed with respect to the bidirectional electric slide rail one in the left and right parts.

[0016] By adopting the above technical solution, the bidirectional electric slide rail three is mainly used to achieve the mutual approach of the two bidirectional electric slide rails two, so as to move the two cross plates after clamping closer to the edge of the web plate after clamping.

[0017] Furthermore, the bidirectional electric slide rail 1 is located at the center of the rotating plate, and the two clamping plates 1 are symmetrically distributed relative to the center of the rotating plate, and the ball bearings are rollingly connected to the clamping plates 1.

[0018] By adopting the above technical solution, the bidirectional electric slide rail drives the two clamps to approach each other to clamp the upper and lower surfaces of the web, so as to achieve the initial limiting of the floating plate. The design of the ball is to ensure that the web can slide flexibly relative to the clamp in the horizontal direction when the cross plate is docked after clamping, thereby ensuring that the web is in the center position after the web is aligned and tightly attached to the cross plate.

[0019] Furthermore, the operation panel is electrically connected to the bidirectional electric slide rail 1, the bidirectional electric slide rail 2, the bidirectional electric slide rail 3, the bidirectional electric slide rail 4 and the rotating motor.

[0020] By adopting the above technical solution, the operation panel mainly controls the orderly opening and closing of the two-way electric slide rail one, the two-way electric slide rail two, the three-way electric slide rail three, the four-way electric slide rail four and the rotating motor by controlling the on and off of the circuit.

[0021] (III) Beneficial effects

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] In order to solve the problem that the clamping and positioning device of the existing H-beam assembly machine can reliably clamp and fix the web and cross plate of the H-beam during welding, during the entire clamping and positioning process, due to the fixed position of the welding part of the cross plate and the web, the welding part of the web and the cross plate of the H-beam cannot be flexibly displaced and adjusted according to actual welding needs, resulting in the H-beam being easily mismatched with the welding head of the welding equipment during the entire welding process, resulting in the problem of low efficiency in H-beam welding and assembly. The utility model adopts the coordinated design of the adjustment mechanism and the rotating clamping mechanism, so that after the web and cross plate of the H-beam are clamped and fixed, the rotating plate can be rotated and displaced with the help of the rotating motor on the rotating clamping mechanism, thereby ensuring that the welding part of the web and the cross plate can always face the welding head of the welding equipment, ensuring the efficient progress of the H-beam welding process, and improving the welding and assembly efficiency of the H-beam.
