Description

[0002] Steel structure processing fixtures are an auxiliary tool that must be used in the processing of steel structures. They are mainly used to fix steel structures to ensure their position accuracy during operations such as cutting, welding or drilling, and to avoid movement or deformation of the steel structure, thereby improving processing accuracy and efficiency.

[0003] During the use of the existing steel structure processing tooling fixture, Shana placed the steel structure on the L-shaped plate, and then drove the electric cylinder to drive the L-shaped plate close to the U-shaped fixture. At this time, the steel structure can be clamped between the L-shaped plate and the U-shaped fixture to fix the steel structure.

[0004] However, since the sides of the U-shaped clamp and the L-shaped plate that are in contact with the steel structure are both flat, they are in surface contact when clamping the plate-like steel structure, which can prevent the plate-like steel structure from moving. However, when clamping the steel structure with a circular arc surface, the surface contact between the U-shaped clamp and the L-shaped plate and the steel structure with the circular arc surface will change to line contact, thereby reducing the clamping effect. Therefore, an adjustable steel structure processing tooling clamp is proposed to solve the above problem. Utility Model Content

[0032] When clamping a plate-like steel structure, first remove the nut 5 and the pressure frame 6, then move the steel structure and place it on the support frame 3, at this time the support frame 3 can support the steel structure, then install the pressure frame 6 and the nut 5 in sequence, at this time the support frame 3 and the pressure frame 6 can clamp the plate-like steel structure, when clamping a steel structure with a circular arc surface, the clamping process is the same as that of the plate-like steel structure, but when placing the steel structure with a circular arc surface, use the lower top plate 8 to support it, and after installing the pressure frame 6, use the upper top plate 7 and the lower top plate 8 to clamp it, so using the semi-circular upper top plate 7 and the lower top plate 8, it can achieve the purpose of surface contact when clamping the steel structure with a circular arc surface, thereby achieving the effect that the device can clamp both the plate-like steel structure and the steel structure with a circular arc surface.

[0033] Reference Figure 1 and Figure 3 The support frame 3 and the pressing frame 6 are both set to be L-shaped, and the support frame 3 and the driving pressing frame 6 are combined to form a transverse concave shape. A through hole is opened on the top of the pressing frame 6, and the threaded rod 4 is inside the through hole, and the bottom surface of the nut 5 is in contact with the top surface of the pressing frame 6.

[0034] By setting the support frame 3 and the pressure frame 6 to be L-shaped, the support frame 3 and the pressure frame 6 can be installed together to form a concave shape, so that the steel structure can be clamped, and the threaded rod 4 passes through the pressure frame 6, so when the nut 5 is rotated, the bottom surface of the nut 5 will exert pressure on the pressure frame 6, thereby making it close to the support frame 3, thereby achieving the purpose of clamping the steel structure.

[0035] Reference Figure 1 , Figure 3 and Figure 4A first clamping rod 9 is fixedly connected to the outer middle part of one side of the support frame 3 close to the pressing frame 6, and the first clamping rod 9 is slidably connected to the outer middle part of the one side of the pressing frame 6 close to the support frame 3, and a second clamping rod 12 is fixedly connected to the middle part of one side of the pressing frame 6 close to the support frame 3, and the second clamping rod 12 is slidably connected to the middle part of one side of the support frame 3 close to the pressing frame 6.

[0037] Reference Figure 1 and Figure 2 The driving assembly includes a bidirectional screw 13 and a motor 14. The bidirectional screw 13 is threadedly connected to the support plate 2. The bottom surface of the support plate 2 is slidably connected to the top surface of the workbench 1. One end of the bidirectional screw 13 is rotatably connected to the mounting plate 20. The mounting plate 20 is fixedly connected to the top surface of the workbench 1. The front side of the top surface of the workbench 1 is fixedly connected to a cover shell 15. The other end of the bidirectional screw 13 is inside the cover shell 15. The other end of the bidirectional screw 13 is fixedly connected to a first bevel gear. The motor 14 is installed on the outer side of the cover shell 15. The output end of the motor 14 is fixedly connected to a rotating shaft 16. The rotating shaft 16 is rotatably connected to the inside of the cover shell 15. The outer side of the rotating shaft 16 is fixedly connected to a second bevel gear, and the first bevel gear and the second bevel gear are meshingly connected.

[0038] The driving motor 14 can drive the rotating shaft 16 to rotate, and the rotating shaft 16 can drive the second bevel gear to rotate, and the second bevel gear can drive the first bevel gear to rotate. At this time, the first bevel gear will drive the bidirectional screw 13 to rotate, so that the two adjacent support plates 2 can be moved closer to or farther away from each other, and steel structures of different sizes can be supported and clamped, thereby improving the applicability of the device.

[0039] Reference Figure 1 , Figure 2 and Figure 3The bottom of the outer wall of the support plate 2 is fixedly connected with a limit plate 17, and the outer side of the limit plate 17 is slidably connected with a guide plate 18, and the guide plate 18 is fixedly connected to the top surface of the workbench 1. The limit plate 17 is set in a T shape, and a through hole is opened in the middle of the guide plate 18. The limit plate 17 is slidably connected to the inside of the guide plate 18. The top of one side of the support plate 2 is fixedly connected with a reinforcing plate 19, and the top surface of the reinforcing plate 19 is fixedly connected to the bottom surface of the support frame 3.

[0040] When two adjacent plates are brought closer to or farther away from each other, the limit plate 17 will be driven to slide inside the guide plate 18. At this time, the through hole inside the guide plate 18 can provide space for the sliding of the limit plate 17, and by setting the limit plate 17 to a T shape, the limit plate 17 and the guide plate 18 can be engaged with each other, thereby improving the stability of the connection between the two, and utilizing the reinforcement plate 19 and improving the structural strength between the support frame 3 and the support plate 2, thereby improving the bearing capacity of the device.

[0041] Working principle: When in use, first remove the nut 5, then remove the pressing frame 6 from the top of the supporting frame 3, then the steel structure can be placed on the supporting frame 3, and the driving motor 14 drives the rotating shaft 16 and the second bevel gear to rotate, and the second bevel gear will drive the first bevel gear and the bidirectional screw 13 to rotate, so as to adjust the distance between the two adjacent supporting plates 2 and the supporting frame 3, so as to adapt to the width of different steel structures. At this time, the supporting frame 3 is used to support the steel structure to complete the placement of the steel structure, and then the pressing frame 6 is installed on the top of the supporting frame 3, and finally the nut 5 is installed and rotated. When the pressure frame 6 is installed, the upper top plate 7 and the lower top plate 8 will contact the outer wall of the steel structure with the circular arc surface. At this time, the surface contact between the device and the steel structure with the circular arc surface can be achieved, thereby improving the clamping effect of the steel structure with the circular arc surface.
