Description

Technical Field

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

[0002] In the field of steel structure manufacturing, the role of fixtures is crucial. The fixture is not only used to fix and support the workpiece to be processed, but also greatly affects the processing accuracy and efficiency. However, there are many problems in the use of existing steel structure fixtures, which limit their application effects, specifically in the following aspects:

[0003] First, the existing steel structure clamps are mostly designed for specific structures and have a narrow scope of application. The design of such special clamps failed to fully consider the diversity of steel structures, resulting in the inability of existing clamps to effectively fix steel structures of different specifications and shapes. This limitation requires factories to equip factories with multiple clamps for different types of steel structures, which not only increases equipment costs, but also increases operational complexity and maintenance difficulty.

[0004] Secondly, the fixing effect of traditional clamps is generally poor, and they can usually only be fixed from a single direction. Due to the changing shapes and processing requirements of steel structures, fixing from a single direction alone cannot provide sufficient support. During the processing, the steel structure is prone to loosening, resulting in reduced processing accuracy and even the risk of workpiece falling off. This not only affects product quality, but may also cause safety hazards.

[0005] In summary, the existing steel structure clamp devices have many deficiencies in terms of applicability and fixing effect, and there is an urgent need for a new clamp device that can be widely applied to different types of steel structures and has a stable fixing effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0037] Please refer to Figures 1-5A clamp device for steel structure manufacturing includes an assembly bracket and a longitudinal clamping component, a transverse clamping component, and a flipping component mounted on the assembly bracket. The longitudinal clamping component moves up and down in the vertical direction and is linked with the flipping component, and the transverse clamping component moves in the horizontal direction.

[0038] The longitudinal clamping assembly includes a lifting seat 21, a clamping plate 22, a guide rod 23 arranged in the vertical direction, and a longitudinal adjustment screw 24. The guide rod 23 is fixedly installed in the assembly bracket, and the longitudinal adjustment screw 24 is rotatably installed in the assembly bracket. The lifting seat 21 maintains a sliding connection with the guide rod 23 and a rotational connection with the longitudinal adjustment screw 24, and the clamping plate 22 maintains a rotational connection with the lifting seat 21.

[0039] The flip assembly includes a rotating seat 41 and a driving rod 42 which are fixedly connected. The rotating seat 41 is rotatably mounted on the assembly bracket and is arranged on the same vertical axis as the lifting seat 21. The guide rod 23 is slidably plugged with the clamping plate 22.

[0040] The transverse clamping assembly includes a transverse adjustment screw 31 and two groups of symmetrically arranged clamping brackets 32 . The clamping brackets 32 are slidably mounted on the assembly bracket and are rotationally connected to the transverse adjustment screw 31 .

[0041] The provision of the assembly bracket can ensure that the longitudinal clamping assembly, the transverse clamping assembly and the flip assembly are stably assembled and operated thereon, and can achieve effective fixation of the processed and manufactured steel structure.

[0042] The clamp device provided in the present application is mainly used to effectively fix structures such as H-shaped steel, I-shaped steel, channel steel, angle steel and steel plates.

[0043] In the longitudinal clamping assembly, the setting of the guide rod 23 can ensure that the lifting seat 21 and the clamping plate 22 can be stably lifted and lowered in the vertical direction. When the longitudinal adjustment screw 24 is driven to operate stably, the lifting seat 21 and the clamping plate 22 assembled on the lifting seat 21 can be driven to be stably lifted and lowered in the vertical direction, and cooperate with the bottom of the assembly bracket to apply longitudinal force to different steel structures, thereby realizing the longitudinal clamping and fixation of the steel structure.

[0044] In the transverse clamping assembly, the transverse adjusting screw 31 is provided with thread grooves with opposite spiral directions at both ends. The two sections of the thread grooves are respectively screwed to the two groups of clamping brackets 32. When the transverse adjusting screw 31 is driven to operate stably, the two groups of clamping brackets 32 can be driven to move relative to or opposite to each other in the horizontal direction. The two groups of clamping brackets 32 work together to apply a transverse force to the steel structure, thereby realizing the transverse clamping and fixation of the steel structure.

[0045] In the flipping assembly, when driving the rotation seat 41 to operate, it can drive the driving rod 42 to rotate within a range of 90° around the axis where the lifting seat 21 is located, and then drive the clamping plate 22 to rotate synchronously around the lifting seat 21, so as to adjust the inclination angle of the clamping plate 22 on the horizontal plane, which is convenient for effectively clamping and fixing the steel structure, or for loading the steel structure into the assembly bracket and clamping and fixing it.

[0046] To ensure that the longitudinal clamping assembly, the transverse clamping assembly, and the flipping assembly can be stably assembled and operated on the assembly bracket, and to ensure the stable operation of each component, the following technical solutions are provided.

[0047] The assembly bracket includes a bottom plate 11, side plates 12 fixedly connected to both sides of the bottom plate 11, and wing plates 13 fixedly connected to the tops of the side plates 12. The wing plates 13 are arranged on both sides of the tops of the side plates 12. Guide through grooves 111 are opened on both sides of the bottom plate 11, and assembly plates 112 arranged outside the guide through grooves 111 are fixedly connected to both sides of the bottom plate 11.

[0048] There are four groups of longitudinal clamping assemblies, which are respectively assembled on each group of wing plates 13. A set of flipping assemblies are provided for each group of longitudinal clamping assemblies. Guide rods 23 and longitudinal adjustment lead screws 24 are arranged between the wing plates 13 and the bottom plate 11.

[0049] The clamping bracket 32 is slidably installed in the guide through groove 111, and the transverse adjustment lead screw 31 is rotatably installed between the two assembly plates 112.

[0050] The bottom plate 11, side plates 12, wing plates 13, assembly plates 112 in the assembly bracket, and the opened guide through grooves 111 are processed from a whole piece of steel plate by cutting and bending. It has strong integrity, good structural strength and stability, and thus ensures the stable assembly of the longitudinal clamping assembly, the transverse clamping assembly, and the flipping assembly on it.

[0051] Among the four groups of longitudinal clamping assemblies, the longitudinal clamping assemblies on the two wing plates 13 arranged in the same straight line direction are symmetrically arranged, while the transverse clamping assembly is arranged in the middle of the assembly bracket, that is, at the position between the two longitudinal clamping assemblies on both sides, which can effectively avoid spatial movement interference when the transverse clamping assembly and the longitudinal clamping assembly are operating, and can also ensure the effective clamping and fixing of the steel structure.

[0052] When the clamping plate 22 in the longitudinal clamping assembly is driven by the flipping assembly and flips from the direction along the length direction of the wing plate 13 to the direction perpendicular to the length direction of the wing plate 13, the top of the assembly bracket can be opened, which is convenient for loading the processed steel structure into the assembly bracket from the top.

[0053] To ensure that the clamping plate 22 cooperates with the bottom plate 11 of the assembly bracket to longitudinally fix the steel structure therein, and to ensure that the two groups of clamping brackets 32 cooperate to transversely fix the steel structure, the following technical solutions are provided.

[0054] The lower surfaces of the clamping plates 22 of each group are fixedly assembled with upper clamping seats 221, the upper surfaces of the bottom plates 11 are fixedly assembled with lower clamping seats 113, and the lower clamping seats 113 are arranged directly below the upper clamping seats 221; the inner sides of the two groups of clamping brackets 32 are fixedly assembled with lateral clamping seats 321, and the two groups of lateral clamping seats 321 are arranged horizontally opposite to each other; the upper clamping seats 221, the lower clamping seats 113, and the lateral clamping seats 321 are all fixedly installed in a detachable manner.

[0055] The upper clamping seats 221 are driven by the longitudinal clamping components to move up and down, and cooperate with the lower clamping seats 113 fixed to the bottom plates 11 to longitudinally fix the steel structure. The two groups of lateral clamping seats 321 are driven by the transverse clamping components to move towards each other to transversely fix the steel structure. Under the combined action of the longitudinal clamping components and the transverse clamping components, H-shaped steel, I-beam, channel steel, angle steel, steel plates, etc. loaded into the assembly bracket can be effectively fixed.

[0056] Taking H-shaped steel as an example, the upper clamping seats 221 are acted on by the longitudinal clamping components to fit with the upper flange of the H-shaped steel, and the lower clamping seats 113 support its lower flange to achieve longitudinal fixation of the H-shaped steel. The two groups of lateral clamping seats 321 transversely fix the web of the H-shaped steel.

[0057] Taking a steel plate as an example, the upper clamping seats 221 and the lower clamping seats 113 respectively clamp the upper and lower surfaces of the steel plate, and the transverse clamping components are in an open position and do not act.

[0058] The upper clamping seats 221 are fixed to the clamping plates 22 through bolt assemblies, the lower clamping seats 113 are fixed to the bottom plates 11 through bolt assemblies, and the lateral clamping seats 321 are fixed to the corresponding clamping brackets 32 through bolt assemblies. It has the advantages of being convenient for disassembling, replacing, and maintaining each clamping seat.

[0059] To facilitate the control of the lifting movement of the clamping plates 22 in each group of longitudinal clamping components, the following technical solutions are provided.

[0060] The bottoms of the longitudinal adjusting lead screws 24 of each group are fixedly connected with transmission bevel gears 241. The bottom of the bottom plate 11 is fixedly connected with a mounting plate 114. A horizontally arranged driving shaft 25 is rotatably installed on the mounting plate 114. Two driving bevel gears 251 are fixedly connected to the driving shaft 25, and the two driving bevel gears 251 are respectively engaged with the two transmission bevel gears 241.

[0061] The mounting plate 114 is fixed to the lower surface of the base plate 11 by welding. Two sets of driving bevel gears 251 on a set of driving shafts 25 can cooperate with the transmission bevel gears 241 on the longitudinal adjustment screws 24 in the two sets of longitudinal clamping assemblies. Therefore, two sets of driving shafts 25 are installed under the base plate 11. Each set of driving shafts 25 can drive the two sets of longitudinal clamping assemblies arranged in the same straight line direction to operate.

[0062] A hand wheel A252 is fixedly connected to the end of the driving shaft 25, and the driving hand wheel A252 drives the driving shaft 25 and the driving bevel gear 251 to operate, thereby driving the two sets of transmission bevel gears 241 and the longitudinal adjustment screw 24 to operate, so as to drive the two sets of corresponding lifting seats 21 and clamping plates 22 to realize lifting movement.

[0063] According to the assembly direction (symmetrical or in the same direction) of the two sets of driving bevel gears 251 on the driving shaft 25, the spiral direction of the threaded grooves on the two associated sets of longitudinal adjustment screws 24 is designed to ensure that when the driving shaft 25 synchronously drives the two sets of adjustment screws to operate, it can drive the associated lifting seat 21 and the clamping plate 22 to rise and fall synchronously.

[0064] A hand wheel B311 is fixedly connected to the end of the lateral adjustment screw 31 , and the lateral adjustment screw 31 can be driven to operate stably by driving the hand wheel B311 .

[0065] In order to ensure that the flip assembly can be stably assembled on the assembly bracket and conveniently drive the flip assembly to operate, the following technical solution is provided.

[0066] The wing plate 13 and the base plate 11 are provided with arc guide grooves 14 which are arranged vertically opposite to each other. The driving rod 42 is assembled into the arc guide groove 14 in a relatively sliding manner. The flip assembly also includes an assembly shell 43 and a matching combination of a worm wheel 44 and a worm 45. The worm wheel 44 is coaxially fixedly connected with the rotating seat 41. The assembly shell 43 is fixedly installed on the wing plate 13 and arranged on the periphery of the rotating seat 41 and the worm wheel 44. The worm 45 is rotatably installed on the assembly shell 43.

[0067] The setting of the arc guide groove 14 can ensure that the driving rod 42 can stably operate along its own operating trajectory, thereby driving the clamping plate 22 to maintain synchronous operation. The assembly shell 43 can play a protective role and stably install the worm 45.

[0068] A knob 451 disposed outside the assembly housing 43 is fixedly connected to the end of the worm 45 . The worm 45 is driven to rotate by turning the knob 451 , thereby driving the worm wheel 44 , the rotating seat 41 , and the driving rod 42 to operate stably.

[0069] The combination of the worm gear 44 and the worm 45 has the functions of speed reduction, torque increase and self-locking, which facilitates the stable operation of driving the worm gear 44, the rotating seat 41 and the driving rod 42 through the worm 45. After the attitude adjustment of the clamping plate 22 is completed, the power at the worm gear 44 end cannot be transmitted to the worm 45, so that the clamping plate 22 is in a locked state, ensuring the attitude stability of the clamping plate 22.

[0070] To ensure the stable support of the assembly bracket, a support frame 15 is fixedly connected to the bottom of the assembly bracket, and a relief notch 151 is provided on the support frame 15.

[0071] The setting of the support frame 15 can ensure the stable erection of the fixture device to effectively clamp and fix the steel structure to be processed. The relief notch 151 provided thereon can prevent spatial movement interference between the support frame 15 and components such as the drive shaft 25 and the lateral adjustment lead screw 31.
