Description

Technical Field

[0001] The utility model relates to the technical field of positioning jigs, in particular to a steel beam welding positioning jig. Background Art

[0002] As the main structural type of modern buildings, steel structures are usually composed of components such as steel beams, steel columns and steel trusses. When welding mutually connected steel beams, positioning jigs are needed to assist in clamping the steel beams so as to enable stable welding of the steel beams.

The rotating mechanism includes a U-shaped bracket, a cylinder, a bearing, a first gear and a second gear. The bearing is sleeved on the outer wall of the cylinder, and the inner ring of the bearing is fixedly connected with the outer wall of the cylinder. Although the device can clamp the steel by the cooperation of a cylinder, an arc-shaped clamping plate, a cylinder and a U-shaped bracket, and drive the steel to rotate through the rotating mechanism, so as to achieve the purpose of not needing to adjust the welding angle of the steel, however, when only clamping the steel by a single cylinder and an arc-shaped clamping plate in cooperation with a cylinder, the steel is in an eccentric position on the cylinder. Therefore, when the cylinder drives the steel thereon to rotate, the rotation amplitude of the steel changes greatly, which is not convenient for the staff to carry out stable welding work on the steel; and the U-shaped bracket is a fixed installation structure, which is not convenient to adjust the height, and there are certain limitations; and the device does not have a structure for synchronously clamping and fixing two mutually butted steels. Therefore, there is room for further improvement in this device.

A rotatable cylinder 4 is sleeved between the two connecting sleeves 3. A driving mechanism 5 is arranged between the n-shaped frame 2 and the cylinder 4. Through the driving mechanism 5, the cylinder 4 can be driven to rotate smoothly. On the right part of the cylinder 4, two cylinders 40 are symmetrically penetrated. The ends of the telescopic rods of the two cylinders 40 are both connected with clamping blocks 41. Through the two symmetrically arranged clamping blocks 41, the steel beam can be clamped and fixed, and the steel beam can be kept at the central position of the cylinder 4. On the right side of the base 1, there are two sleeves 6. A connecting rod 7 is slidably sleeved in the two sleeves 6. A support seat 8 is connected between the upper ends of the two connecting rods 7. The support seat 8 is arranged in a U structure, which is convenient for the stable placement of the steel beam. An adjusting part is connected between the bottom of the support seat 8 and the base 1. By controlling the adjusting part, the height of the support seat 8 can be conveniently adjusted, which is easy to use. A positioning sleeve 9 is connected to the right side of the cylinder 4. A clamping mechanism is arranged at the rear side of the base 1. The clamping mechanism includes a bracket 10, a guide rod frame 11, a guide rail 12, an electric bidirectional lead screw 13, clamping blocks 14, a rotating screw 15 and a turntable 16. A bracket 10 is arranged in the middle at the rear side of the base 1. A guide rod frame 11 is slidably penetrated through the front side of the top of the bracket 10. The bottom of the guide rod frame 11 is connected with a guide rail 12. An electric bidirectional lead screw 13 is installed on the guide rail 12. Clamping blocks 14 that can be horizontally slid and adjusted in position are symmetrically sleeved on the guide rail 12, and the clamping blocks 14 are respectively threadedly connected with the electric bidirectional lead screw 13. By controlling the operation of the electric bidirectional lead screw 13, the two clamping blocks 14 thereon can be driven to close to each other, so as to clamp and fix the two butt-jointed steel beams, which is beneficial to the precise welding of the steel beam. The front side of the top of the bracket 10 is rotatably connected with a rotating screw 15, and the rotating screw 15 is threadedly connected with the guide rod frame 11. The upper end of the rotating screw 15 is connected with a turntable 16. By rotating the turntable 16, the height of the clamping block 14 can be correspondingly adjusted.

[0023] Further, as Figures 1-3 shown, the driving mechanism 5 includes a driving motor 50, a gear 51 and a gear ring 52. A driving motor 50 is installed on the top of the n-shaped frame 2. A gear 51 is connected to the output shaft of the driving motor 50 through a coupling. A gear ring 52 is sleeved in the middle of the outer wall of the cylinder 4, and the gear 51 meshes with the gear ring 52. By controlling the operation of the driving motor 50, under the transmission of the gear 51 and the gear ring 52, the cylinder 4 can be driven to rotate synchronously.

[0024] Further, as Figure 1 、 Figure 3 and Figure 6As shown in the figure, the adjusting member includes an adjusting tube 80 and a threaded rod 81. The right side of the base 1 is rotatably connected to the adjusting tube 80. The outer wall of the adjusting tube 80 is provided with an anti-slip rubber strip, which can play an anti-slip role. The middle position at the bottom of the support base 8 is connected to the threaded rod 81, and the threaded rod 81 is threadedly connected to the adjusting tube 80. By rotating the adjusting tube 80, the height of the support base 8 thereon can be adjusted, which is convenient to use.

[0025] Furthermore, as Figures 1-4 shown, the positioning sleeve 9 is arranged in a conical structure that is narrower on the left and wider on the right, which is beneficial for guiding the placed steel beam so that the steel beam can be conveniently placed at the center position of the cylinder 4.

[0026] In addition, as Figures 1-3 shown, it also includes a collection box 17. Two sliding grooves 18 are opened in the middle of the base 1.

[0027] During use, place one of the steel beams into the cylinder 4. Under the guiding action of the positioning sleeve 9, the steel beam can be conveniently placed at the center of the cylinder 4 and between the two clamping blocks 41. By controlling the cylinder 40 to extend its telescopic rod, the clamping blocks 41 thereon can be driven to move closer to each other, and then the steel beam can be clamped and fixed to ensure that the clamped steel beam is just located at the center of the cylinder 4. Then place the other steel beam on the support base 8, and the height can be adjusted by rotating the adjusting tube 80 so that the threaded rod 81 can drive the support base 8 thereon to move and adjust the height, so that the two steel beams to be welded can be accurately aligned. Furthermore, it is beneficial for clamping and aligning steel beams of different diameters, with a wide range of applications; and by rotating the turntable 16, the rotating screw 15 can drive the clamping block 14 to move and adjust the position, control the electric bidirectional lead screw 13 to operate, so that the two clamping blocks 14 can move closer to each other and close, and then the two accurately docked steel beams can be clamped and fixed axially. Furthermore, it is beneficial for the staff to accurately weld the clamped steel beam. When the steel beam needs to be rotated, control the electric bidirectional lead screw 13 to separate the clamping blocks 14 thereon, and rotate the turntable 16 to make the guide rod frame 11, the guide rail 12, the electric bidirectional lead screw 13 and the clamping block 14 move upward to reset. Control the driving motor 50 to operate. Through the transmission of the gear 51 and the gear ring 52, the cylinder 4 and the steel beam thereon can be driven to rotate smoothly. In this way, it is beneficial for the steel beam to maintain an even rotation amplitude, and further beneficial for the staff to weld the steel beam smoothly, which is convenient to use.
