Description

Technical Field

[0001] This invention relates to the field of welding auxiliary equipment technology, and more specifically to a high-efficiency welding auxiliary device for steel pipes used in the maintenance of unmanned aerial vehicles. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and onboard program control devices. UAVs are actually a general term for unmanned aerial vehicles. From a technical point of view, they can be divided into several categories: unmanned helicopters, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airships, and unmanned paragliders. UAVs are generally composed of fuselage, wings, tail, landing gear, automatic flight control system, and power system. The fuselage is the most basic structural frame of the UAV, and most of the components are placed in the fuselage. The fuselage is generally made of titanium alloy steel pipes welded together to form a preliminary frame.

[0003] The shortcomings of existing technologies: In the process of butt welding of steel pipes, since the welding part of the two steel pipes is arc-shaped, the two steel pipes need to be connected, spliced ​​and fixed together during welding. Moreover, the splicing methods are diverse and complex, with various angles. It is difficult to position steel pipes with different angles. To address this, we propose an efficient steel pipe welding auxiliary device for unmanned aerial vehicle maintenance. Summary of the Invention

A second rotating seat is mounted on the upper end of the movable plate. A pair of driven shafts are rotatably connected within the second rotating seats. All driven wheels are mounted on the circumferential surfaces of the driven shafts.

[0007] Preferably, both the fixed plate and the movable plate are provided with a clamping mechanism. The clamping mechanism includes a clamping frame, a clamping wheel, a support plate and a first spring. Multiple sets of clamping frames are rotatably connected to both the fixed plate and the movable plate through a rotating rod. Each clamping frame is rotatably connected with a clamping wheel. Multiple sets of support plates are respectively installed at the lower ends of the fixed plate and the movable plate. The first spring is installed between the clamping frame and the support plate.

[0008] Preferably, a threaded rod is rotatably connected inside the translation frame, and the threaded rod is threadedly connected to the fixed plate.

[0009] Preferably, a drive motor is mounted on the surface of the support frame, a drive rod is mounted on the output end of the drive motor, the drive rod and the drive shaft are connected by a sprocket set, a connecting rod is slidably connected inside the drive shaft, the right end of the connecting rod is tapered, a connecting groove is opened on the left end face of the driven shaft, and the dimensions of the connecting rod and the connecting groove are matched.

[0010] Preferably, a worm gear is mounted on the circumferential surface of the rotating shaft, a rotating shaft is rotatably connected to the lower end of the connecting block via a rotating frame, a worm is mounted on the circumferential surface of the rotating shaft, the worm gear meshes with the worm, and a reset and correction column is mounted on the lower end of the movable plate, the reset and correction column being in contact with the connecting block.

[0011] Preferably, a gear is rotatably connected inside the reset and correction column, and the first rack and the second rack, which are slidably connected inside the reset and correction column, both mesh with the gear. A second spring is installed between the first rack and the reset and correction column. A mounting bracket installed at the upper end of the second rack is slidably connected to the movable plate and the reset and correction column. A limit tooth block is installed at the upper end of the mounting bracket, and a limit tooth groove is formed on the circumferential surface of the driven shaft.

[0012] Preferably, the connecting block has angle grooves on both its left and right end faces, and the connecting frame has an angle pointer installed on its surface, the angle pointer corresponding to the angle groove.

[0013] Preferably, an electric push rod is installed at the upper end of the adjusting frame, the output end of the electric push rod is fixedly connected to the connecting seat, and a rotary motor is installed at the rear end of the connecting seat, the output end of the rotary motor is fixedly connected to the rotating column.

[0014] The technical effects and advantages of this invention are as follows:

[0015] This invention involves bringing one steel pipe closer to another, bringing the two pipes together. Then, the drive shaft and driven shaft can be rotated, causing the drive wheel and driven wheel to rotate simultaneously, allowing the two pipes to rotate synchronously. At this point, the operator can use a welding torch to weld the two pipes together. Furthermore, the guide column can be used to control the upward movement of the connecting seat, adjusting the height of the rotating column to align it with the center of the steel pipe on the fixed plate. Then, the connecting frame is controlled to rotate on the connecting block, adjusting the angle of the steel pipe on the movable plate. Once the appropriate angle is reached, it is fixed. The position of the steel pipe on the movable plate is then adjusted, and finally, the fixed plate is moved on the translation frame, causing one end of the steel pipe on the fixed plate to adhere to the circumference of the steel pipe on the movable plate. The drive shaft is then controlled to rotate, driving the drive wheel to rotate, while the rotating column rotates at the same speed as the drive shaft. This allows the two steel pipes to rotate while adhering, and the operator can then use a welding torch to move along the joint of the two pipes, thus achieving the welding effect.

[0016] When the movable plate rotates at a controlled angle, the lower end of the first rack disengages from the connecting block. Then, through the action of the second spring, the first rack moves downward, causing the gear to rotate. The gear then moves the second rack upward, causing the mounting bracket and the limiting tooth block to move upward, making the limiting tooth block engage with the driven shaft. Simultaneously, through the cooperation of the limiting tooth groove, the driven shaft is locked, thus preventing the driven shaft and driven wheel from rotating. After adjusting the angle of the steel pipe on the movable plate, the rotation of the steel pipe can prevent the connection position from becoming difficult to locate, improving the stability of the steel pipe connection.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The efficient welding auxiliary device for steel pipes for unmanned aerial vehicle maintenance involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figure 1-5As shown, in one embodiment, a high-efficiency welding auxiliary device for steel pipes used in the maintenance of unmanned aerial vehicles is proposed, including a base 1. A support frame 101 and an adjustment frame 102 are installed on the upper end of the base 1. A fixed positioning component 2 is installed on the surface of the support frame 101. A movable positioning component 3 is provided inside the adjustment frame 102. The fixed positioning component 2 includes a translation frame 201, a fixed plate 202, a drive shaft 204, and drive wheels 205. The translation frame 201 is installed on the surface of the support frame 101. The fixed plate 202 is slidably connected inside the translation frame 201. A first rotating seat 203 is installed on the upper end of the translation frame 201. A pair of drive shafts 204 are rotatably connected inside the first rotating seat 203. The drive wheels 205 are all installed on the circumferential surface of the drive shafts 204.

[0031] The movable positioning component 3 includes guide posts 301, connecting seats 302, rotating posts 303, movable plates 307, driven shafts 309, and driven wheels 3010. Multiple guide posts 301 are slidably connected within the adjusting frame 102. The connecting seats 302 are installed on the circumferential surface of the guide posts 301. The rotating posts 303 are rotatably connected within the connecting seats 302. A connecting block 304 is installed on the end face of the rotating posts 303. The connecting block 304 is rotatably connected to the connecting frame 306 via a rotating shaft 305. The movable plate 307 is installed on the upper end of the connecting frame 306. A second rotating seat 308 is installed on the upper end of the movable plate 307. A pair of driven shafts 309 are rotatably connected within the second rotating seat 308. The driven wheels 3010 are all installed on the circumferential surface of the driven shafts 309.

[0032] In practical application, the two steel pipes that need to be welded together are fixed on the fixed plate 202 and the movable plate 307 respectively. Then, the fixed plate 202 is controlled to move on the translation frame 201, thereby driving one of the steel pipes to move closer to the other steel pipe, so that the two steel pipes are in contact. Then, the drive shaft 204 and the driven shaft 309 can be controlled to rotate, driving the drive wheel 205 and the driven wheel 3010 to rotate simultaneously, so that the two steel pipes can rotate synchronously. At this time, the operator can operate the welding gun to weld the two steel pipes together.

[0033] When welding one steel pipe to the circumference of another, an angle will exist between the pipes. Once the two pipes are at the same heights on the fixed plate 202 and the movable plate 307 respectively, the guide column 301 controls the upward movement of the connecting seat 302, adjusting the height of the rotating column 303 to align it with the center of the steel pipe on the fixed plate 202. Then, the connecting frame 306 rotates on the connecting block 304, adjusting the angle of the steel pipe on the movable plate 307. Once the appropriate angle is reached, the current steel pipe... The angle is fixed, then the position of the steel pipe on the movable plate 307 is adjusted, and finally the fixed plate 202 is pushed to move on the translation frame 201 so that one end of the steel pipe on the fixed plate 202 is attached to the circumferential surface of the steel pipe on the movable plate 307. Then the drive shaft 204 is controlled to rotate, driving the drive wheel 205 to rotate. At the same time, the rotating column 303 is controlled to rotate at the same speed as the drive shaft 204. At this time, the two steel pipes can rotate when they are attached, and the operator can operate the welding torch to move along the joint of the two steel pipes, thereby achieving the effect of welding the steel pipes.

[0034] like Figure 1 , 2 As shown in Figure 4, in a preferred embodiment of the present invention, both the fixed plate 202 and the movable plate 307 are provided with a clamping mechanism 4. The clamping mechanism 4 includes a clamping frame 401, a clamping wheel 402, a support plate 403 and a first spring 404. Both the fixed plate 202 and the movable plate 307 are rotatably connected to multiple sets of clamping frames 401 via rotating rods. Each clamping frame 401 is rotatably connected to a clamping wheel 402. Multiple sets of support plates 403 are respectively installed at the lower ends of the fixed plate 202 and the movable plate 307. The first spring 404 is installed between the clamping frame 401 and the support plate 403.

[0035] In practical application, when the steel pipe is placed on the drive wheel 205 and the driven wheel 3010, the clamping frame 401 is pushed by the first spring 404. The clamping frame 401 then pushes the clamping wheel 402 to move inward, so that the clamping wheel 402 squeezes the steel pipe below, thereby achieving the effect of fixing the position of steel pipes of different diameters. At the same time, when the drive wheel 205 or the driven wheel 3010 rotates, the rotation of the steel pipe can be controlled, which facilitates subsequent welding operations.

[0036] like Figure 2 and 3 As shown, in another preferred embodiment of the present invention, a threaded rod 5 is rotatably connected inside the translation frame 201, and the threaded rod 5 is threadedly connected to the fixing plate 202.

[0037] In practical applications, rotating the threaded rod 5 can control the lateral position of the fixed plate 202 on the translation frame 201, thereby adjusting the position of one of the steel pipes so that one of the steel pipes is tightly pressed together with the other steel pipe, improving the subsequent welding effect.

[0038] like Figure 1 , 8 As shown in Figure 9, in another preferred embodiment of the present invention, a drive motor 6 is mounted on the surface of the support frame 101, and a drive rod 601 is mounted on the output end of the drive motor 6. The drive rod 601 and the drive shaft 204 are connected by a sprocket set 602. A connecting rod 603 is slidably connected inside the drive shaft 204. The right end of the connecting rod 603 is tapered, and a connecting groove 604 is provided on the left end face of the driven shaft 309. The dimensions of the connecting rod 603 and the connecting groove 604 are matched.

[0039] In practical application, the embodiments of the present invention control the operation of the drive motor 6, which drives the drive rod 601 to rotate. The drive rod 601, through the sprocket set 602, can drive the drive shaft 204 to rotate, thereby achieving the effect of controlling the rotation of the drive wheel 205. When the connecting rod 603 is inserted into the connecting groove 604 opened in the driven shaft 309, since the connecting rod 603 is polygonal, when the drive shaft 204 rotates, it can synchronously drive the driven shaft 309 to rotate, thereby achieving the effect of synchronous rotation of the driven shaft 309 and the drive shaft 204 at the same speed. At the same time, it drives the two steel pipes that are in contact with it to rotate, which facilitates the completion of subsequent welding operations.

[0040] like Figure 4 , 5 As shown in Figures 10 and 11, in another preferred embodiment of the present invention, a worm gear 7 is mounted on the circumferential surface of the rotating shaft 305, and a rotating shaft 701 is rotatably connected to the lower end of the connecting block 304 via a rotating frame. A worm 702 is mounted on the circumferential surface of the rotating shaft 701, and the worm gear 7 meshes with the worm 702. A reset and correction column 703 is mounted on the lower end of the movable plate 307, and the reset and correction column 703 is in contact with the connecting block 304.

[0041] In one embodiment of the present invention, when it is necessary to control the movable plate 307 to reset, the reset correction column 703 provides a support point, which can ensure the stability of the movable plate 307 after reset.

[0042] In practical application, the rotating shaft 701 drives the worm gear 702 to rotate, the worm gear 702 drives the worm wheel 7 to rotate, the worm wheel 7 drives the rotating shaft 305 to rotate, the rotating shaft 305 drives the connecting frame 306 to rotate, and the connecting frame 306 drives the movable plate 307 to rotate by an angle, thereby achieving the effect of controlling the angle adjustment of the steel pipe on the movable plate 307, which facilitates the splicing and welding of steel pipes at different angles.

[0043] like Figure 5-7As shown, in another preferred embodiment of the present invention, a gear 704 is rotatably connected inside the reset and correction column 703. The first rack 705 and the second rack 706, which are slidably connected inside the reset and correction column 703, both mesh with the gear 704. A second spring 707 is installed between the first rack 705 and the reset and correction column 703. The mounting bracket 708 installed on the upper end of the second rack 706 is slidably connected to the movable plate 307 and the reset and correction column 703. A limiting tooth block 709 is installed on the upper end of the mounting bracket 708. A limiting tooth groove 7010 is formed on the circumferential surface of the driven shaft 309.

[0044] In practical application, when the movable plate 307 rotates, the lower end of the first rack 705 disengages from the connecting block 304. Then, through the action of the second spring 707, the first rack 705 moves downward, driving the gear 704 to rotate. The gear 704 drives the second rack 706 to move upward, and the second rack 706 drives the mounting bracket 708 and the limiting tooth block 709 to move upward, so that the limiting tooth block 709 engages with the driven shaft 309. At the same time, through the cooperation of the limiting tooth groove 7010, the driven shaft 309 can be locked, thereby preventing the driven shaft 309 and the driven wheel 3010 from rotating. After the angle of the steel pipe on the movable plate 307 is adjusted, the rotation of the steel pipe can prevent the connection position from being difficult to locate, thus improving the stability of the steel pipe connection.

[0045] like Figure 5 As shown, in another preferred embodiment of the present invention, angle grooves 8 are provided on both the left and right end faces of the connecting block 304, and an angle pointer 801 is installed on the surface of the connecting frame 306, the angle pointer 801 corresponding to the angle groove 8.

[0046] In practical applications, when the connecting frame 306 rotates, it will drive the angle pointer 801 to rotate. With the cooperation of the angle groove 8, the angle of the movable plate 307 can be precisely adjusted, and the steel pipes can be spliced ​​and fixed at different angles.

[0047] like Figure 1 , 4 As shown in Figures 10 and 11, in another preferred embodiment of the present invention, an electric push rod 9 is installed on the upper end of the adjusting frame 102, the output end of the electric push rod 9 is fixedly connected to the connecting seat 302, and a rotary motor 901 is installed at the rear end of the connecting seat 302, the output end of the rotary motor 901 is fixedly connected to the rotating column 303.

[0048] In practical application, by controlling the operation of the electric push rod 9, the height of the movable plate 307 and the rotating column 303 can be adjusted so that the center of the rotating column 303 is aligned with the center of the steel pipe on the fixed plate 202. Adjustments can be made for steel pipes of different diameters. After the angle of the steel pipe on the movable plate 307 is adjusted, the steel pipe on the height plate and the steel pipe on the movable plate 307 are spliced ​​at a predetermined angle. At this time, the rotary motor 901 and the drive motor 6 can be controlled to rotate synchronously, driving the rotating column 303 and the drive wheel 205 to rotate synchronously. This allows the two steel pipes to achieve a rotation effect while remaining relatively stationary, which facilitates welding between the steel pipes.

[0049] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
