Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a pipe fitting assembly welding device. Background Technology

[0002] When welding pipe fittings, it is sometimes necessary to connect four square pipe fittings end to end to form a rectangular frame. However, the following problems exist when assembling the rectangular frame: (1) It is necessary to manually splice the square pipes and then weld them with a welding gun. The square pipes are prone to misalignment during welding, resulting in unstable welding; (2) Since the length and width of the rectangular frame to be assembled are different, the length of the square pipes to be welded is also different. The current welding equipment is difficult to connect square pipes of different lengths end to end, resulting in poor compatibility. Utility Model Content

[0003] In view of the shortcomings of the prior art, the present invention provides a pipe fitting assembly and welding device to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A pipe fitting assembly and welding device includes a chassis with a frame connected to it. A first slide is connected to the frame via a first screw drive mechanism. A second slide is connected to the bottom surface of the first slide via a second screw drive mechanism. A first cylinder is mounted on the bottom surface of the second slide, and a welding torch is connected to the telescopic end of the first cylinder. The first slide is driven to move left and right via the first screw drive mechanism, and the second slide is driven to move back and forth via the second screw drive mechanism. Third screw drive mechanisms are provided on both the left and right sides of the chassis, and third slides are connected to these third screw drive mechanisms, which can drive the third slides to move left and right. Fourth screw drive mechanisms are provided on both the front and rear sides of the chassis, and fourth slides are driven to these fourth screw drive mechanisms, which can drive the fourth slides to move back and forth. Positioning mechanisms are installed on both the third and fourth slides.

[0006] Preferably, a set of positioning mechanisms is installed on the third slide, and two sets of positioning mechanisms are installed on the fourth slide.

[0007] In the above technical solution, a set of positioning mechanisms on the third slide can clamp a shorter square tube, while two sets of positioning mechanisms on the fourth slide can clamp a longer square tube.

[0008] Preferably, the positioning mechanism includes a support platform, a bearing plate connected to the support platform, a baffle connected to one side of the bearing plate, a connecting plate installed on the side of the support platform away from the baffle, a second cylinder connected to the connecting plate, and a pressure plate connected to the telescopic end of the second cylinder. The pressure plate is located above the bearing plate, and a screw hole is provided at the lower end of the support platform.

[0009] The above technical solution involves placing the square tube on the support plate, then controlling the second cylinder to contract, causing the pressure plate to descend and press the tube tightly onto the support plate. A baffle can prevent the square tube from slipping off the support plate.

[0010] Preferably, the chassis has a discharge port at its center, located between the third and fourth slides. The chassis contains a drawer-type storage basin, and a discharge hopper is connected to the discharge port, with the discharge hopper communicating with the storage basin.

[0011] In the above technical solution, the debris generated during welding falls into the discharge port and then enters the storage basin through the discharge hopper, preventing debris from splashing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The shorter square tube is fixed by the positioning mechanism on the third slide, and the longer square tube is fixed by the positioning mechanism on the fourth slide. The two long square tubes and the two short square tubes are connected end to end. Then, through the action of the first screw drive mechanism and the second screw drive mechanism, the welding gun is driven to the top of the connection of the square tubes, and the connection of the square tubes is welded together by the welding gun, thereby completing the welding of the rectangular frame and greatly improving the welding efficiency.

[0014] The third slide is driven to move left and right by the third lead screw transmission mechanism, and the fourth slide is driven to move back and forth by the fourth lead screw transmission mechanism. This allows it to adapt to square tubes of different lengths, so as to weld rectangular frames of different lengths and widths, thus improving the adaptability of welding.

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] Example 1

[0022] Please see Figures 1-4 A pipe fitting assembly and welding device includes a housing 1, a frame 2 connected to the housing 1, a first slide 3 connected to the frame 2 via a first screw drive mechanism 17, a second slide 4 connected to the bottom surface of the first slide 3 via a second screw drive mechanism 18, a first cylinder 5 mounted on the bottom surface of the second slide 4, and a welding torch 6 connected to the telescopic end of the first cylinder 5. The first screw drive mechanism drives the first slide 3 to move left and right, and the second screw drive mechanism drives the second slide 4 to move back and forth. Third screw drive mechanisms 19 are provided on both the left and right sides of the housing 1, and third slides 7 are connected to them via these mechanisms. The third screw drive mechanisms can drive the third slides 7 to move left and right. Fourth screw drive mechanisms 20 are provided on both the front and rear sides of the housing 1, and fourth slides 8 are connected to them via these mechanisms. The fourth screw drive mechanisms can drive the fourth slides 8 to move back and forth. Positioning mechanisms for fixing square tubes are installed on both the third slides 7 and the fourth slides 8.

[0023] Specifically, the third slide 7 is equipped with a set of positioning mechanisms for fixing shorter square tubes, and the fourth slide 8 is equipped with two sets of positioning mechanisms for fixing longer square tubes.

[0024] In this embodiment, the positioning mechanism includes a support platform 9, a bearing plate 10 connected to the support platform, a baffle 11 connected to one side of the bearing plate, a connecting plate 12 installed on the support platform away from the baffle, a second cylinder 13 connected to the connecting plate, and a pressure plate 14 connected to the telescopic end of the second cylinder. The pressure plate 14 is located above the bearing plate 10, and a screw hole is provided at the lower end of the support platform 9. The square tube is placed on the bearing plate 10, and then the second cylinder 13 is controlled to retract, causing the pressure plate 14 to descend and press the tube tightly onto the bearing plate 10. The baffle 11 prevents the square tube from slipping off the bearing plate.

[0025] The first lead screw transmission mechanism 17, the second lead screw transmission mechanism 18, the third lead screw transmission mechanism 19, and the fourth lead screw transmission mechanism 20 described in this embodiment all use a motor to drive the lead screw to rotate. When the lead screw rotates, it drives the slide to make linear motion. This kind of transmission structure and method is existing technology. Therefore, this embodiment will not describe the specific structure and principle of each lead screw transmission mechanism in detail.

[0026] The working principle of this embodiment is as follows: the third slide 7 is driven to move left and right by the third lead screw transmission mechanism 19, and the fourth slide 8 is driven to move back and forth by the fourth lead screw transmission mechanism 20, thereby adapting to square tubes 21 of different lengths and positioning them. After the square tubes 21 are fixed, adjacent square tubes 21 are connected end to end. Then, through the action of the first lead screw transmission mechanism 17 and the second lead screw transmission mechanism 18, the welding torch 6 is driven to reach above the connection point of each square tube, and the connection point of each square tube is welded together by the welding torch, thereby completing the welding of the rectangular frame.
