Description

Technical Field

[0001] The utility model relates to the field of steel structures, in particular to a positioning device used for welding processing of steel structure columns and beams. Background Art

[0002] Steel structures are mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopt rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. During the production process of steel structures, welding operations need to be performed using welding devices. After the production of most steel structure columns and beams, end plates need to be welded at the ends of the columns and beams to facilitate the subsequent connection and fixation of the steel structure columns and beams. However, during the welding process, the staff usually welds the end plates to the ends of the columns and beams based on experience, which can easily cause large deviations and affect subsequent installation. Summary of the invention

[0003] The technical problem to be solved by the utility model is that during the welding process, workers usually weld and fix the end plate at the end position of the column beam based on their experience, which easily causes a large deviation and affects the subsequent installation.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a positioning device for welding processing of steel structure columns and beams, including a workbench, a steel body and an end plate, the steel body is placed horizontally on the workbench, the end plate is located at the end of the steel body, a limit assembly is slidably provided on the upper end of the workbench, and an adjustment assembly for adjusting the height of the end plate is provided at the end of the workbench.

[0005] The beneficial effect of the utility model is that the limit assembly is arranged slidably, so that the end of the steel body is inserted into the limit assembly to drive the limit assembly to move, automatically adjust the position of the limit assembly, and avoid the need for staff to align and adjust the steel body and the limit assembly.

[0006] As a further improvement of the utility model, the technical problem to be solved is: it is difficult to weld and fix ends of different sizes.

[0007] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the adjustment component includes a movable plate and a fixed plate fixed at the end of the workbench, an adjustment bolt is threaded through the middle of the fixed plate, the upper end of the adjustment bolt is rotatably connected to the lower end of the movable plate, and the side wall of the movable plate is in sliding contact with the end of the workbench.

[0008] The beneficial effect of the above improvement is as follows: through the mutual cooperation of the fixed plate, the movable plate and the adjusting bolts, the staff turns the adjusting bolts to drive the movable plate to move up and down, adjusts the height of the movable plate, and then when the end plate is placed on the movable plate, ensures that the upper and lower ends of the end plate are at the same distance from the surface of the steel body. By adjusting the height of the movable plate, end plates of different sizes can be placed conveniently.

[0009] As a further improvement of the utility model, the technical problem to be solved is: it is difficult to ensure that the distances between the left and right ends of the end plate and the surface of the column beam are the same.

[0010] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the limit assembly includes a shell and two mounting shells symmetrically and slidably arranged on the upper end of the workbench, and constraint blocks are respectively slidably provided on the opposite sides of the two mounting shells, and the two constraint blocks are connected to the mounting shells through connecting springs. The two constraint blocks are in an inclined shape away from the shell side, and a T-shaped slider is fixedly provided at the lower end of the two mounting shells. A sliding groove matching the T-shaped slider is provided on the upper end surface of the workbench, a bidirectional screw rod is rotatably provided in the shell, and a handwheel matching the bidirectional screw rod is rotatably provided on one side of the shell, and the bidirectional screw rod is symmetrically sleeved with two threaded seats, and the two mounting shells are respectively connected to the threaded seats through connecting parts.

[0011] The beneficial effect of the above improvement is as follows: by inserting one end of the steel body between the two constraint blocks, and then placing the end plate at the end position of the steel body, that is, between the shell and the constraint block, the two threaded seats are driven to move by rotating the bidirectional screw, and then the connecting parts are driven to move, and the two sides of the end plate are clamped by the relative movement of the two connecting parts, effectively ensuring that the end plate is in the center position of the end of the steel body.

[0012] The utility model further improves the technical solution adopted as follows: the connecting piece includes a connecting shell and a slide plate slidably arranged inside the connecting shell, the connecting shell is fixedly connected to the threaded seat, a compression spring and a connecting plate are respectively arranged on one side of the slide plate, the compression spring is fixedly connected to the inside of the connecting shell, and one end of the connecting plate movably passes through the outside of the connecting shell and is fixedly connected to the mounting shell.

[0013] The beneficial effect of the above improvement is as follows: by setting a connecting shell, a connecting plate, a sliding plate and a compression spring, the staff pulls the shell outward to increase the distance between the shell and the constraint block. At this time, the compression spring is in a compressed state, which is convenient for the staff to place the end plate between the shell and the constraint block. Then, under the resetting action of the compression spring, the shell moves to one side of the constraint block, thereby achieving the effect of limiting the end plate.

[0014] The utility model further improves the technical solution adopted as follows: a fixing block is fixedly arranged on one side opposite to the two connecting plates, and a ball is rotatably embedded in the two fixing blocks on one side away from the shell.

[0015] The beneficial effect of the above improvement is: by setting the fixed block and the ball, the ball can roll on the outer surface of the end plate, avoiding the relative movement of the two connecting shells to clamp and constrain the two sides of the end plate, which causes the end plate and the outer surface of the shell to have a large friction, making it more difficult for the staff to turn the handwheel.

[0016] The utility model further improves the technical solution adopted as follows: a handle is fixedly provided on the outer side of the shell.

[0017] The beneficial effect of the above improvement is that by providing a handle, it is easier for the staff to pull the shell outwards. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0024] like Figure 1-4 As shown, a positioning device for welding steel structure columns and beams includes a workbench 1, a steel body 2 and an end plate 8. The steel body 2 is horizontally placed on the workbench 1, and the end plate 8 is located at the end of the steel body 2. A limit assembly for constraining the end plate 8 is slidably provided on the upper end of the workbench 1, and an adjustment assembly for adjusting the height of the end plate 8 is provided at the end of the workbench 1. The limit assembly is slidably provided, so that the end of the steel body 2 is inserted into the limit assembly to drive the limit assembly to move, and the position of the limit assembly is automatically adjusted, so that the staff does not need to align and adjust the steel body 2 with the limit assembly.

[0025] The adjustment assembly includes a movable plate 4 and a fixed plate 3 fixed at the end of the workbench 1. An adjustment bolt 5 is threaded through the middle of the fixed plate 3. The upper end of the adjustment bolt 5 is rotatably connected to the lower end of the movable plate 4, and the side wall of the movable plate 4 is in sliding contact with the end of the workbench 1. Through the cooperation of the fixed plate 3, the movable plate 4 and the adjustment bolt 5, the staff rotates the adjustment bolt 5 to drive the movable plate 4 to move up and down, adjust the height of the movable plate 4, and then when the end plate 8 is placed on the movable plate 4, it is ensured that the upper and lower ends of the end plate 8 are at the same distance from the surface of the steel body 2. By adjusting the height of the movable plate 4, it is convenient to place end plates 8 of different sizes.

[0026] The limit assembly includes a housing 9 and two mounting shells 7 symmetrically slidably arranged on the upper end of the workbench 1. The two mounting shells 7 are respectively provided with a constraint block 11 slidingly penetrated on the opposite side. The two constraint blocks 11 are connected to the mounting shell 7 through a connecting spring 12. The two constraint blocks 11 are inclined on the side away from the housing 9. The lower ends of the two mounting shells 7 are fixed with a T-shaped slider. The upper end surface of the workbench 1 is provided with a slide groove 6 that matches the T-shaped slider. A bidirectional screw rod 15 is rotatably arranged in the housing 9. A hand wheel that matches the bidirectional screw rod 15 is rotatably arranged on one side of the housing 9. The bidirectional screw rod 15 is symmetrically sleeved with two threaded seats 18. The two mounting shells 7 are respectively connected to the threaded seats 18 through connecting pieces. By inserting one end of the steel body 2 between the two constraint blocks 11, and then placing the end plate 8 at the end position of the steel body 2, that is, between the housing 9 and the constraint block 11, the two threaded seats 18 are driven to move by rotating the bidirectional screw rod 15, and then the connecting piece is driven to move. The two sides of the end plate 8 are clamped by the relative movement of the two connecting pieces, effectively ensuring that the end plate 8 is at the center position of the end of the steel body 2.

[0027] The connecting member includes a connecting shell 16 and a slide plate 19 slidably arranged inside the connecting shell 16. The connecting shell 16 is fixedly connected to the threaded seat 18. A compression spring 20 and a connecting plate 17 are respectively arranged on one side of the slide plate 19. The compression spring 20 is fixedly connected to the inside of the connecting shell 16. One end of the connecting plate 17 movably passes through the outside of the connecting shell 16 and is fixedly connected to the mounting shell 7. By providing the connecting shell 16, the connecting plate 17, the slide plate 19 and the compression spring 20, the staff pulls the shell 9 outward to increase the distance between the shell 9 and the constraint block 11. At this time, the compression spring 20 is in a compressed state, which is convenient for the staff to place the end plate 8 between the shell 9 and the constraint block 11. Then, under the resetting action of the compression spring 20, the shell 9 moves toward the side of the constraint block 11 to achieve the effect of limiting the end plate 8.

[0028] The two connecting plates 17 are fixed with fixed blocks 13 on opposite sides, and the two fixing blocks 13 are rotatably embedded with balls 14 on the sides away from the housing 9. By providing the fixed blocks 13 and the balls 14, the balls 14 can roll on the outer surface of the end plate 8, so as to avoid the large friction between the end plate 8 and the outer surface of the housing 9 when the two connecting shells 16 move relative to each other to clamp and constrain the two sides of the end plate 8, and it is more difficult for the staff to turn the hand wheel.

[0029] A handle 10 is fixedly provided on the outside of the housing 9. By providing the handle 10, it is convenient for the staff to pull the housing 9 outwards better.
