Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure production equipment, and in particular relates to an assembly fixture for a steel structure production line. Background Art

[0002] Steel structure refers to a structural form that can bear and transfer loads and is made of steel plates and hot-rolled, cold-bent or welded profiles connected by connectors. The steel structure system has the comprehensive advantages of light weight, factory manufacturing, quick installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. Compared with reinforced concrete structures, it has unique advantages in the three aspects of "high and light". Globally, especially in developed countries and regions, steel structures are reasonably and widely used in the field of construction engineering. The steel structure industry is usually divided into five subcategories: light steel structure, high-rise steel structure, residential steel structure, space steel structure and bridge steel structure.

[0003] Welding is a very important step in the production process of a steel structure production line. Before welding two components, a special assembly fixture is used to fix and clamp the two steel structure components. In particular, after the tubular steel structure is assembled and clamped and welded at one point, the staff is required to manually rotate the tubular steel structure. At this time, it is very likely that the pipe mouth of the tubular steel structure will be offset and misaligned, and the alignment process is cumbersome, affecting the final welding quality. In addition, the assembly fixture in traditional technology has a single function and only has a clamping effect. In order to prevent cold cracks, hot cracks and hardened structures from appearing at the welding points of the tubular steel structure, the tubular steel structure is generally transferred to another heating device for preheating before and after welding, which is time-consuming and labor-intensive, and has low processing efficiency. Therefore, a steel structure production line assembly fixture that can solve the above-mentioned technical problems is provided. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a pairing fixture for a steel structure production line.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] A pair of fixtures for a steel structure production line, comprising a base plate, a first mounting plate fixedly connected to one side of the base plate, a motor connected to one side of the first mounting plate, an output rod of the motor connected to a left three-jaw chuck, a slide rail connected to one side of the base plate, a threaded rod connected to the slide rail, a manual turntable connected to the end of the threaded rod, a matching nut sleeve connected to the outer wall of the threaded rod shaft, a first slider connected to the nut sleeve, the first slider connected to an electric cylinder through a transfer plate, an end of the electric cylinder connected to a second mounting plate, the second mounting plate rotatably connected to a rotating rod, and the rotating rod connected to the right three-jaw chuck;

[0007] The slide rail is slidably connected to a second slide block on one side of the first slide block, the second slide block is slidably connected to the outer wall of the threaded rod shaft, the upper side of the second slide block is connected to a U-shaped mounting plate, the U-shaped mounting plate is connected to an electric telescopic rod, the end of the electric telescopic rod is connected to a mounting ring, and the mounting ring is provided with a mounting cavity evenly connected to multiple infrared heating tubes.

[0008] It is further defined that the first mounting plate and the second mounting plate are both fixedly connected with an arc-shaped anti-drop plate. Such a structural design can prevent the clamped tubular steel structure from falling directly, thereby improving safety.

[0009] It is further defined that L-shaped limit sliders are connected to both sides of the U-shaped mounting plate, the ends of the L-shaped limit sliders are chamfered, and the bottom plate is provided with limit slide grooves adapted to the sliding of the L-shaped limit sliders. Such a structural design can enhance the stability of the U-shaped mounting plate during movement.

[0010] It is further defined that the first slider and the second slider are both arranged in a dovetail shape, and the edge corners are arranged in a rounded shape. Such a structural design makes it less likely for the first slider and the second slider to get stuck and slide more smoothly.

[0011] It is further defined that one end of the rotating rod is connected to a limiting disc, the axis of the limiting disc is provided with a plurality of sockets, and a limiting rod is inserted between the second mounting plate and the single socket. Such a structural design enables the rotation angle of the rotating rod to be manually limited and fixed when there is no need to adjust the angle of the right three-jaw chuck, thereby enhancing the stability of the right three-jaw chuck.

[0012] The beneficial effects of the utility model are:

[0013] 1. The utility model can automatically move the tubular steel structure clamped by the three-jaw chuck on the right side to contact and connect to the tubular steel structure clamped by the three-jaw chuck on the left side, so as to facilitate and quickly automatically limit and fix the two sections of tubular steel structure and to butt joint them, which is convenient for subsequent welding. After welding one side, the tubular steel structure is driven by a motor to rotate and adjust the welding angle position, so that the tubular steel structure does not need to be clamped repeatedly, and the displacement and dislocation of the pipe mouth of the tubular steel structure are prevented, and the butt joint time is shortened;

[0014] 2. Multiple infrared heating tubes connected by mobile installation rings preheat and heat the welding surface before and after welding to prevent cold cracks, hot cracks and hardened structure problems at the welding points of tubular steel structures. It is convenient and quick, and there is no need to repeatedly clamp and transfer the tubular steel structure, which saves time and effort and improves processing efficiency.

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-3 As shown, a pair of fixtures for a steel structure production line of the utility model comprises a base plate 1, a first mounting plate 101 is fixedly connected to one side of the base plate 1, a motor 102 is connected to one side of the first mounting plate 101, an output rod of the motor 102 is connected to a left three-jaw chuck 103, a slide rail 2 is connected to one side of the base plate 1, a threaded rod 201 is connected to the slide rail 2, a manual turntable 2011 is connected to the end of the threaded rod 201, a matching nut sleeve 202 is connected to the outer wall of the threaded rod 201 shaft body, the nut sleeve 202 is connected to a first slider 203, the first slider 203 is connected to an electric cylinder 2032 through a transfer plate 2031, the end of the electric cylinder 2032 is connected to a second mounting plate 204, the second mounting plate 204 is rotatably connected to a rotating rod 205, and the rotating rod 205 is connected to a right three-jaw chuck 206;

[0026] The slide rail 2 is slidably connected to the second slider 3 on one side of the first slider 203, the second slider 3 is slidably connected to the outer wall of the threaded rod 201, the upper side of the second slider 3 is connected to a U-shaped mounting plate 301, the U-shaped mounting plate 301 is connected to an electric telescopic rod 302, the end of the electric telescopic rod 302 is connected to a mounting ring 303, the mounting ring 303 is provided with a mounting cavity 3031 evenly connected to a plurality of infrared heating tubes 304.

[0027] In the embodiment of the present case, the staff clamps the two sections of tubular steel structure to be welded to the left three-jaw chuck 103 and the right three-jaw chuck 206 respectively, and then rotates the manual turntable 2011, the manual turntable 2011 drives the threaded rod 201 to rotate, and the threaded rod 201 drives the nut sleeve 202 and the first slider 203 to move along the slide rail 2 when rotating, until the end of the tubular steel structure clamped by the right three-jaw chuck 206 contacts and connects to the end of the tubular steel structure clamped by the left three-jaw chuck 103, and then manually moves the U-shaped mounting plate 301 according to the contact welding surface of the two sections of tubular steel structure, the U-shaped mounting plate 301 drives the second slider 3 and each connecting component to move toward the welding surface until the mounting ring 303 surrounds the outside of the welding surface, and then turns on each infrared heating tube 304 through the central controller, and each infrared heating tube 304 is turned on to locally preheat the welding surface;

[0028] After preheating for a period of time, the installation ring 303 and its connecting components are moved away from the welding surface, and the welding surface is welded by an external welding device. When one side of the welding surface is welded, the motor 102 is turned on, and the output rod of the motor 102 drives the left three-jaw chuck 103 to rotate. At this time, since one side of the two sections of the tubular steel structure has been welded, the left three-jaw chuck 103 drives the two sections of the tubular steel structure to rotate around the rotating rod 205 as the axis when rotating, so as to flexibly adjust the upward welding surface and welding angle. After welding is completed, the position of the installation ring 303 is moved to the outside of the welding point, and each infrared heating tube 304 is turned on to locally heat the welding surface.

It is convenient and quick, and there is no need to repeatedly clamp and transfer the tubular steel structure, which saves time and effort, improves processing efficiency, makes the overall function of the device more diverse, and achieves the purpose of improving production efficiency;

[0030] Among them, the electric telescopic rod 302 and the electric cylinder 2032 can conveniently adjust the height position of the installation ring 303 and the single-sided tubular steel structure according to needs, so as to adapt to the processing of tubular steel structures of different sizes.

[0031] Preferably, the first mounting plate 101 and the second mounting plate 204 are both fixedly connected with an arc-shaped anti-drop plate 4. Such a structural design can prevent the clamped tubular steel structure from falling directly, thereby improving safety.

Such a structural design can enhance the stability of the U-shaped mounting plate 301 during movement. In fact, other structural shapes that can enhance the stability of the movement of the U-shaped mounting plate 301 can also be considered according to specific circumstances.

[0033] Preferably, the first slider 203 and the second slider 3 are both dovetail shaped, and the edges and corners are rounded. This structural design makes it easier for the first slider 203 and the second slider 3 to slide smoothly without getting stuck. In fact, other structural shapes that can prevent sliding jams can also be considered according to specific circumstances.

[0034] Preferably, one end of the rotating rod 205 is connected to the limiting disc 207, the limiting disc 207 is provided with a plurality of plug holes 2071, and the limiting plug rod 208 is inserted between the second mounting plate 204 and the single plug hole 2071.
