Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a clamp for processing steel structure beams. Background Art

[0002] Before assembling the steel structure, it is often necessary to spray paint on its surface to prevent structural damage caused by surface corrosion during use. When spraying paint on the surface of the steel structure, it is often necessary to fix the steel structure on a fixture and then spray paint it through a spray paint device.

[0003] According to a publicly disclosed fixture for painting the surface of a steel structure (publication number: CN112138903A), it includes a base, a slider, a clamping mechanism and a limiting mechanism; sliders are provided at both ends of the base, and a rotating shaft is rotatably provided in the slider; the inner end of the rotating shaft is provided with a clamping mechanism for clamping the steel structure, and the outer end is provided with a limiting mechanism for limiting the rotating shaft. The above application document provides a limiting mechanism to facilitate positioning of the steel structure after flipping it, so that the steel structure can be painted in all directions, but the device sprays paint while clamping, making it difficult for the clamped area to be covered by paint, resulting in incomplete painting.

[0005] The clamping assembly includes a sliding groove, a sliding block is slidably connected to the outer side of the sliding groove, a hydraulic chamber is fixedly connected to the inside of the sliding block, a joystick is slidably connected to the piston at one end of the hydraulic chamber, a gear rod is slidably connected to the piston at the other end of the hydraulic chamber, the side of the sliding block is rotatably connected to a rotating shaft, a gear is fixedly connected to the top of the rotating shaft, and a splint is fixedly connected to the side of the rotating shaft.

[0006] Preferably, the gear is located on a side of the gear rod away from the central axis of the base, and the gear is in meshing state with the gear rod, so that when the gear rod moves, the gear can rotate accordingly.

[0007] Preferably, two clamping plates are provided, and the two clamping plates are symmetrically distributed about the central axis of the base, and the two clamping plates can be rotated to clamp the steel structure.

[0008] Preferably, a clamping assembly is provided on the side of the sliding block;

[0010] Preferably, the fixing groove is located at a side position of the sliding block, and the limiting groove is located at a front end position of the joystick.

[0011] Preferably, two limiting grooves are provided, and the cross-section shapes of the two limiting grooves are the same as the cross-section shape of the clamping rod, so that the operating rod can be restricted in different states.

[0012] The utility model provides a fixture for processing steel structure beams, which has the following beneficial effects:

[0013] (1) The fixture for processing steel structure beams places the steel structure on a base. By moving the operating lever, in conjunction with the hydraulic bin, gear rod, gear, shaft, splint, operating table, paint port, sliding groove, and sliding block, the steel structure can be painted without dead angles, so that it can be completely painted, further improving the painting effect.

[0014] (2) Before moving the operating lever, the fixture for processing the steel structure beam rotates the torsion spring rod with the torsion spring rod as the axis, thereby driving the clamping rod fixedly connected to the torsion spring rod to move, so that the clamping rod moves out of the restriction groove. At this time, the operating lever is no longer restricted, thereby reducing the possibility of accidentally touching the operating lever without moving the operating lever.

[0022] The clamping assembly includes a sliding groove 4, a sliding block 5 is slidably connected to the outer side of the sliding groove 4, a hydraulic chamber 6 is fixedly connected to the inside of the sliding block 5, a piston at one end of the hydraulic chamber 6 is slidably connected to a joystick 7, and a piston at the other end of the hydraulic chamber 6 is slidably connected to a gear rod 8, a rotating shaft 9 is rotatably connected to the side of the sliding block 5, a gear 10 is fixedly connected to the top of the rotating shaft 9, the gear 10 is located on the side of the gear rod 8 away from the central axis of the base 1, and the gear 10 is in a meshing state with the gear rod 8. The steel structure is placed on the base 1, and the hydraulic chamber 6 slidably connected to the joystick 7 piston is cooperated by moving the joystick 7, so that the pressure in the hydraulic chamber 6 is increased, driving the gear rod 8 slidably connected to the piston of the hydraulic chamber 6 to move The rotating shaft 9 is movable, and a clamping plate 11 is fixedly connected to the side of the clamping plate 11. Two clamping plates 11 are provided, and the two clamping plates 11 are symmetrically distributed about the central axis of the base 1. When the gear rod 8 moves, the gear rod 8 drives the gear 10 meshing therewith to rotate, and the gear 10 drives the rotating shaft 9 fixedly connected thereto to rotate, so that the rotating shaft 9 drives the clamping plate 11 fixedly connected thereto to rotate, and clamps the steel structure. At this time, the operating table 2 is operated to make the paint spraying port 3 to spray paint, and then the clamping plate 11 is released, and the sliding block 5 is moved along the sliding groove 4. Similarly, the operating lever 7 is moved again to clamp the steel structure from another angle for secondary painting. The steel structure can be painted without dead angles, so that it can be completely painted, which further improves the painting effect.

[0023] When in use, place the steel structure on the base 1, and increase the pressure in the hydraulic chamber 6 by moving the joystick 7 and cooperating with the hydraulic chamber 6 slidably connected to the piston of the joystick 7, thereby driving the gear rod 8 slidably connected to the piston of the hydraulic chamber 6 to move, so that the gear rod 8 drives the gear 10 meshing with it to rotate, and the gear 10 drives the rotating shaft 9 fixedly connected to it to rotate, so that the rotating shaft 9 drives the clamping plate 11 fixedly connected to it to rotate, thereby clamping the steel structure.
