Description

Technical Field

[0001] This utility model belongs to the field of metal structure welding technology, specifically referring to a metal structure welding fixture. Background Technology

[0002] Metal frame refers to a frame system made of metal materials that has a certain structure and support function. The steel structure commonly used in buildings is composed of various steel sections (such as I-beams, channel steel, angle steel, etc.) and steel plates connected by welding, bolting and other methods.

[0003] When welding structural steel, it is necessary to fix the structural steel on both sides to be welded. The common method is for workers to use clamps to hold and fix the structural steel on both sides before welding. However, there are some shortcomings in the welding process: although the existing clamps can meet the clamping effect when holding the structural steel, sometimes the structural steel needs to be adjusted up, down, left, and right to weld. The structural steel is relatively heavy, and the existing clamps are not convenient for adjusting the structural steel up, down, left, and right. Therefore, improvements are needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that, in the prior art, it is inconvenient to adjust the horizontal position and height of the weld when welding steel metal structures.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: A metal frame welding fixture includes a base plate, two sets of slide blocks are symmetrically slidably arranged inside the base plate, side grooves are symmetrically arranged in the side walls of the base plate, and a slider is slidably arranged in each side groove. A lateral adjustment device is provided in the base plate and is poweredly connected to the slider. A longitudinal pushing device capable of driving the slide blocks longitudinally is provided on the slider. Two sets of hydraulic cylinders are vertically arranged at the upper end of each set of slide blocks. The output end of the hydraulic cylinder is connected to a V-shaped support groove. A clamping device is fixedly connected to the side wall of the support groove to fix the steel section placed in the support groove.

[0006] Furthermore, the lateral adjustment device includes a motor, which is fixed to the side wall of the substrate. The output end of the motor is connected to a lead screw and threadedly connected to the slider. A slide rod is fixed in the side groove on the other side and passes through the slider. The motor and the lead screw are arranged symmetrically on the left and right.

[0007] Furthermore, the longitudinal sliding device includes a hydraulic cylinder three, which is fixedly connected to a set of sliders. Two sets of limiting rods are symmetrically arranged between the left and right sliders of the hydraulic cylinder three, and the limiting rods pass through the slider.

[0008] Furthermore, the clamping device includes a bracket, which is fixed to the outer wall of the support groove. A second hydraulic cylinder is fixed vertically downward to the top wall of the bracket. The output end of the second hydraulic cylinder is connected to a pressure plate by bolts. The pressure plate is located directly above the support groove.

[0009] Furthermore, a pump station is provided at the upper end of the slide block, and the pump station is connected to the hydraulic pipelines of hydraulic cylinder one, hydraulic cylinder two, and hydraulic cylinder three.

[0010] Furthermore, a guide post is fixedly connected to the lower end face of the support groove, and the guide post is vertically inserted into the slide block.

[0011] The beneficial effects achieved by adopting the above-described structure are as follows:

[0012] 1. This utility model, by setting a horizontal adjustment device, uses a motor to drive the lead screw to rotate, and the lead screw to drive the corresponding slider to slide in the side groove. The limit rod can drive the slide block to slide synchronously, thereby realizing the horizontal left and right sliding adjustment and docking of the steel in the support groove.

[0013] 2. This utility model, by setting a longitudinal pushing device, allows the hydraulic cylinder three to push the slide block to slide back and forth on the limit rod, thereby realizing the adjustment of the front and back position of the steel section. The hydraulic cylinder one can realize the adjustment of the height of the support groove, thereby adjusting the height of the steel section. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] like Figure 1-4 This utility model discloses a metal structure welding fixture, including a base plate 1. Two sets of slide blocks 4 are symmetrically slidably arranged inside the base plate 1. Side grooves 2 are symmetrically arranged in the two side walls of the base plate 1. A slider 3 is slidably arranged in each side groove 2. A lateral adjustment device 5 is provided in the base plate 1 and is poweredly connected to the slider 3. A longitudinal pushing device 6 is provided on the slider 3 to drive the slide block 4 longitudinally. Two sets of hydraulic cylinders 7 are vertically arranged at the upper end of each set of slide blocks 4. The output end of the hydraulic cylinders 7 is connected to a V-shaped support groove 8. A guide post 19 is fixedly connected to the lower end face of the support groove 8. The guide post 19 is vertically inserted into the slide block 4. A clamping device 9 is fixedly connected to the side wall of the support groove 8 to fix the steel section placed in the support groove 8.

[0022] like Figure 1-3 The lateral adjustment device 5 includes a motor 10, which is fixed to the side wall of the base plate 1. The output end of the motor 10 is connected to a lead screw 11 and threadedly connected to the slider 3. A slide rod 12 is fixed in the side groove 2 on the other side and passes through the slider 3. The motor 10 and the lead screw 11 are arranged symmetrically on the left and right. Driven by the lead screw 11, the slider 3 can be driven to slide in the side groove 2. Driven by the longitudinal pushing device 6, the slide block 4 and the slider 3 can slide synchronously, thereby realizing the left and right position adjustment of the steel section.

[0023] like Figure 3-4 The longitudinal sliding device includes a hydraulic cylinder 13, which is fixed to a set of sliders 3. Two sets of limiting rods 14 are symmetrically arranged between the left and right sliders 3. The limiting rods 14 pass through the slide block 4. By pushing the slide block 4 on the limiting rods 14 through the hydraulic cylinder 13, the slide block 4 can be moved longitudinally, thereby realizing the longitudinal position adjustment of the rod.

[0024] like Figure 1-3 The clamping device 9 includes a bracket 15, which is fixed to the outer wall of the support groove 8. A hydraulic cylinder 16 is vertically fixed to the top wall of the bracket 15. A pump station 18 is provided at the upper end of the slide 4. The pump station 18 is connected to the hydraulic pipelines of hydraulic cylinder 7, hydraulic cylinder 16 and hydraulic cylinder 13. The output end of hydraulic cylinder 16 is connected to a pressure plate 17 by bolts. The pressure plate 17 is located directly above the support groove 8. When the steel section is placed in the support groove 8, the pressure plate 17 can be used to clamp the steel section. The pressure plate 17 can be disassembled and replaced. The type of pressure plate 17 can be freely changed according to the shape of the steel section.

[0025] In practical use, the metal structural steel to be welded is placed in the support groove 8. According to the shape of the steel, a matching pressure plate 17 is selected and fixed to the lower end of the hydraulic cylinder 16. The steel is placed in the two sets of support grooves 8 on the upper end of the same side slide 4. Then, by starting the hydraulic cylinder 16, the steel is fixed by the pressure plate 17.

[0026] Before welding, the steel profile needs to be adjusted. By starting the motor 10, the lead screw 11 can drive the slider 3 to slide in the side groove 2, which in turn drives the slide block 4 to slide in the base plate 1 until the steel profiles on the left and right sides are close to be joined. If the front and back positions of the steel profile are not accurate, the hydraulic cylinder 13 can be started to push the slide block 4 to slide on the limit rod 14 to adjust the front and back positions. If the joining height of the steel profile is not accurate, the hydraulic cylinder 7 can be used to push the steel profile upward to finally complete the precise joining of the steel profile. This makes the welding more accurate and also solves the problem of the inconvenience of adjustment in traditional steel profile welding.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
