Description

Technical Field

[0001] This utility model relates to the field of angle iron flange welding technology, specifically a quick positioning device for a four-gun automatic angle iron flange welding equipment. Background Technology

[0002] Angle iron flanges are a common pipe connection component, mainly used for duct connections in ventilation, air conditioning, dust removal and other systems. They are especially widely used in rectangular ducts. Their core structure is a flange frame made of angle steel (equal or unequal sides), which is fixed to the end of the duct by welding, riveting or bolting to achieve a quick and stable connection between ducts.

[0003] During welding of angle iron flanges, local thermal expansion and cooling contraction will generate stress. When welding on one side, the angle iron may bend towards the weld. When welding multiple angle irons, uneven stress will cause the overall frame to deform. The heat-affected zone of welding may cause the position of the machined bolt holes to shift. The components are tightly fixed by positioning fixtures to limit displacement during the welding process.

[0004] In conventional welding, the positioning devices for fixing angle iron flanges typically control the positioning components on all four sides of the flange independently. This makes the connection process with the flange complex, and the distance between some positioning components cannot be adjusted, reducing the applicability of the positioning structure. Therefore, a quick positioning device for a four-gun automatic angle iron flange welding equipment is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a quick positioning device for an automatic welding equipment for four-gun angle iron flanges. It has the advantages of quickly limiting the angle iron flange and solves the problem that in conventional welding positioning devices, when fixing the angle iron flange, most of the positioning components on the four sides of the angle iron flange are controlled separately, making the operation when connecting with the angle iron flange more complicated. In addition, the distance of some positioning components cannot be adjusted, resulting in a decrease in the applicability of the positioning structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick positioning device for an automatic welding equipment for four-gun angle iron flanges, comprising a base, a sliding groove on the top of the base, and a positioning structure fixedly installed on the top of the base;

[0007] The positioning structure includes a fixed box, which is fixedly installed on the top of the base. A bidirectional threaded rod is rotatably installed inside the fixed box. A threaded block is threadedly connected to the outside of the bidirectional threaded rod. The top of the threaded block passes through the fixed box and extends to the outside of the fixed box. An adjusting frame is fixedly installed on the top of the threaded block. A lead screw is rotatably installed inside the adjusting frame. A threaded cross plate is threadedly connected to the outside of the lead screw. A hinge rod is hinged to the outside of the threaded cross plate. Telescopic rods are fixedly installed on both the front and rear sides of the fixed box. A first fixed plate is fixedly installed on the outside of the telescopic rod. A connecting shaft is fixedly installed on the outside of the first fixed plate. A slider is fixedly installed on the bottom of the first fixed plate.

[0008] Furthermore, a second fixing plate is fixedly installed on the top of the adjustment frame, and limit clamps are fixedly installed on the outside of both the second fixing plate and the first fixing plate, with rubber pads fixedly installed inside the limit clamps.

[0009] Furthermore, there are two adjustment frames, which are located on the left and right sides of the top of the fixed box, respectively.

[0010] Furthermore, both ends of the threaded cross plate are hinged with hinge rods, and each pair of hinge rods passes through the front and rear sides of the adjustment frame and extends to the outside of the adjustment frame.

[0011] Furthermore, the other end of the hinge rod is rotatably connected to the connecting shaft, and the slider and the slide groove are slidably connected.

[0012] Furthermore, the two second fixing plates are distributed in a relative state, and the two first fixing plates are distributed in a relative state.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The quick positioning device of this four-gun angle iron flange automatic welding equipment can quickly position the angle iron flange through a second fixed plate, a two-way threaded rod, a threaded block, an adjusting frame, a limit clamp, a lead screw, a threaded cross plate, a hinge rod, a first fixed plate, and a telescopic rod, which facilitates subsequent angle iron flange welding processing. At the same time, the positioning device can also adjust the position of the positioning clamp according to different sizes of angle iron flanges, increasing the applicability of the positioning device.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 The quick positioning device of the automatic welding equipment for four-gun angle iron flange in this embodiment includes a base 1, a sliding groove 2 on the top of the base 1, a positioning structure 3 fixedly installed on the top of the base 1, a second fixing plate 4 on the top of the positioning structure 3, a limit clamp 5 fixedly installed on the outside of the second fixing plate 4 and the first fixing plate 309, and a rubber pad 6 fixedly installed inside the limit clamp 5.

[0022] The positioning structure 3 includes a fixed box 301. The fixed box 301 is fixedly installed on the top of the base 1. A bidirectional threaded rod 302 is rotatably installed inside the fixed box 301. A threaded block 303 is threadedly connected to the outside of the bidirectional threaded rod 302. The top of the threaded block 303 passes through the fixed box 301 and extends to the outside of the fixed box 301. An adjusting frame 304 is fixedly installed on the top of the threaded block 303. A lead screw 305 is rotatably installed inside the adjusting frame 304. A threaded cross plate 306 is threadedly connected to the outside of the lead screw 305. A hinge rod 307 is hinged to the outside of the threaded cross plate 306. Telescopic rods 308 are fixedly installed on both the front and rear sides of the fixed box 301. A first fixing plate 309 is fixedly installed on the outside of the telescopic rod 308. A connecting shaft 310 is fixedly installed on the outside of the first fixing plate 309. A slider 311 is fixedly installed on the bottom of the first fixing plate 309.

[0023] exist Figure 1 In the process, when the bidirectional threaded rod 302 drives the threaded block 303 to move, the hinge rod 307 inside the two adjusting frames 304 will drive the first fixed plate 309 to move synchronously, so that the two first fixed plates 309 and the two second fixed plates 4 always maintain a four-sided state.

[0024] exist Figure 1 In the middle, two connecting shafts 310 are installed on the outside of the two first fixing plates 309, and each pair of connecting shafts 310 is rotatably connected to the hinge rods 307 on the same side inside the two adjusting frames 304.

[0025] exist Figure 1 In the middle, when the telescopic rod 308, the slider 311, and the slide groove 2 move the first fixed plate 309, the movement of the first fixed plate 309 can always be kept horizontal and linear, and the limiting clamps 5 outside the two first fixed plates 309 and the two second fixed plates 4 are also in the same horizontal state.

[0026] During implementation, follow these steps: When in use, first bring the vertical sides of the angle iron flange close to the two second fixing plates 4, then rotate the double-threaded rod 302 so that the limiting clamps 5 on the outside of the two second fixing plates 4 are connected to the vertical sides of the angle iron flange. Then, rotate the screw 305 until the limiting clamps 5 on the outside of the two first fixing plates 309 are connected to the horizontal sides of the angle iron flange, which can quickly position the angle iron flange.

[0027] In summary, the quick positioning device of this four-gun angle iron flange automatic welding equipment first brings the vertical sides of the angle iron flange closer to the two second fixing plates 4. Then, by rotating the bidirectional threaded rod 302, the two threaded blocks 303 drive the two adjusting frames 304 to move, thereby connecting the limiting clamps 5 on the outside of the two second fixing plates 4 with the vertical sides of the angle iron flange. Then, by rotating the screw 305, the position of the threaded horizontal plate 306 is adjusted, which drives the hinge rod 307 to move. This causes the position of the first fixing plate 309 to change through the hinge rod 307, while the telescopic rod 308 extends and retracts. The positioning device can quickly position the angle iron flange by connecting the limiting clamps 5 on the outside of the two first fixing plates 309 to the lateral sides of the angle iron flange. This facilitates subsequent welding and processing of the angle iron flange. At the same time, the positioning device can also adjust the position of the positioning clamps according to different sizes of angle iron flanges, increasing the applicability of the positioning device. This solves the problem that when fixing the angle iron flange in a conventional welding positioning device, most of the positioning parts on the four sides of the angle iron flange are controlled separately, making the operation more complicated when connecting with the angle iron flange. In addition, the distance of some positioning parts cannot be adjusted, which reduces the applicability of the positioning device.
