[0002] An unmanned aerial vehicle is an unpiloted aircraft controlled by radio remote control equipment and self-prepared program control devices. In fact, an unmanned aerial vehicle is a general term for unmanned flying vehicles. From a technical perspective, it can be divided into several categories: unmanned helicopters, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airships, and unmanned parafoil aircraft.

[0013] When the present invention controls the rotation angle of the movable plate, the lower end of the first rack will then disengage from the connecting block. Then, through the action of the second spring, the first rack is driven to move downward. The first rack drives the gear to rotate, and the gear drives the second rack to move upward. The second rack drives the mounting frame and the limiting tooth block to move upward, making the limiting tooth block fit with the driven shaft. At the same time, through the cooperation of the limiting tooth grooves, the driven shaft can be locked, thereby preventing the driven shaft and the driven wheel from rotating. After the angle of the steel pipe on the movable plate is adjusted, it can avoid the difficulty in positioning the connection position caused by the rotation of the steel pipe, improving the stability during the connection of the steel pipes.

Detailed implementation manners

[0016] The technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples, and a high-efficiency welding auxiliary device for steel pipes for unmanned aerial vehicle maintenance involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0017] As Figures 1-5 shown, in one embodiment, a high-efficiency welding auxiliary device for steel pipes for unmanned aerial vehicle maintenance is proposed, including a machine base 1. A support frame 101 and an adjustment frame 102 are installed at the upper end of the machine base 1. A fixed positioning assembly 2 is installed on the surface of the support frame 101. A movable positioning assembly 3 is arranged inside the adjustment frame 102. The fixed positioning assembly 2 includes a translation frame 201, a fixed plate 202, a drive shaft 204 and a drive wheel 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 at 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 shaft 204; The movable positioning component 3 includes guide columns 301, a connecting seat 302, a rotating column 303, a movable plate 307, a driven shaft 309, and a driven wheel 3010. A plurality of guide columns 301 are slidably connected in the adjusting frame 102. The connecting seat 302 is installed on the circumferential surface of the guide column 301. The rotating column 303 is rotatably connected in the connecting seat 302. A connecting block 304 is installed on the end face of the rotating column 303. The connecting block 304 is rotatably connected with a connecting frame 306 through a rotating shaft 305. The movable plate 307 is installed at the upper end of the connecting frame 306. A second rotating seat 308 is installed at the upper end of the movable plate 307. A pair of driven shafts 309 are rotatably connected in the second rotating seat 308. The driven wheels 3010 are all installed on the circumferential surface of the driven shaft 309.

[0018] In practical application of the embodiment of the present invention, two steel pipes to be welded together are respectively fixed on the fixed plate 202 and the movable plate 307. Subsequently, the fixed plate 202 is controlled to move on the translation frame 201, so as to drive one of the steel pipes to approach the other steel pipe, making the two steel pipes fit together. Subsequently, the driving shaft 204 and the driven shaft 309 can be controlled to rotate, driving the driving 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 torch to weld the two steel pipes together; When it is necessary to weld one steel pipe on the circumferential surface of another steel pipe, there will be an angle between the steel pipes at this time. After the two steel pipes are respectively placed on the fixed plate 202 and the movable plate 307, the connecting seat 302 is controlled to move upward through the action of the guide column 301 at this time, adjusting the height of the rotating column 303 to align the center of the steel pipe on the rotating column 303 with the center of the steel pipe on the fixed plate 202. Subsequently, the connecting frame 306 is controlled to rotate on the connecting block 304 to adjust the angle of the steel pipe on the movable plate 307. When the angle is adjusted to the appropriate angle, the current steel pipe angle is fixed. Subsequently, the position of the steel pipe on the movable plate 307 is adjusted. 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 fits on the circumferential surface of the steel pipe on the movable plate 307. Subsequently, the driving shaft 204 is controlled to rotate, driving the driving wheel 205 to rotate, and at the same time, the rotating column 303 is controlled to rotate at the same speed as the driving shaft 204. At this time, the two steel pipes can rotate when they are in contact, 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.

[0019] Such as Figure 1 、 2As shown in FIGS. 4 and 4, as a preferred embodiment of the present invention, a clamping mechanism 4 is provided in both the fixed plate 202 and the movable plate 307. The clamping mechanism 4 includes a clamping frame 401, a clamping wheel 402, a support plate 403, and a first spring 404. A plurality of groups of clamping frames 401 are rotatably connected in the fixed plate 202 and the movable plate 307 through rotating rods. A clamping wheel 402 is rotatably connected in each clamping frame 401. A plurality of groups 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.

[0020] In the actual application of the embodiment of the present invention, when the steel pipe is placed on the driving wheel 205 and the driven wheel 3010, at this time, the clamping frame 401 is pushed by the first spring 404, and the clamping frame 401 will push the clamping wheel 402 to move inward, so that the clamping wheel 402 presses the steel pipe below, thereby realizing the effect of fixing the positions of steel pipes with different diameters. At the same time, when the driving wheel 205 or the driven wheel 3010 rotates, the rotation of the steel pipe can be controlled, which is convenient for subsequent welding operations.

[0021] As Figure 2 and 3 shown, as another preferred embodiment of the present invention, a threaded rod 5 is rotatably connected in the translation frame 201, and the threaded rod 5 is threadedly connected to the fixed plate 202.

[0022] In the actual application of the embodiment of the present invention, when the threaded rod 5 is rotated, the horizontal position of the fixed plate 202 on the translation frame 201 can be controlled, and thus the position of one of the steel pipes can be adjusted, so that one of the steel pipes is closely attached to the other steel pipe by extrusion, improving the subsequent welding effect.

[0023] As Figure 1 、 8 and 9 shown, as another preferred embodiment of the present invention, a driving motor 6 is installed on the surface of the support frame 101. A driving rod 601 is installed at the output end of the driving motor 6. The driving rod 601 and the driving shaft 204 are connected through a sprocket set 602. A connecting rod 603 is slidably connected in the driving shaft 204. The right end of the connecting rod 603 is conical. A connecting groove 604 is opened on the left end face of the driven shaft 309. The connecting rod 603 and the connecting groove 604 are matched in size.

[0024] In practical application of the embodiment of the present invention, the driving motor 6 is controlled to operate. The driving motor 6 drives the driving rod 601 to rotate. The driving rod 601 can drive the driving shaft 204 to rotate through the sprocket group 602, achieving the effect of controlling the rotation of the driving 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 driving shaft 204 rotates, it can synchronously drive the driven shaft 309 to rotate, thereby achieving the effect that the driven shaft 309 rotates synchronously and at the same speed as the driving shaft 204, and at the same time driving the two mutually attached steel pipes to rotate, facilitating the subsequent welding operation.

[0025] As Figure 4 , 5 , 10 and 11 show that, as another preferred embodiment of the present invention, a worm gear 7 is installed on the circumferential surface of the rotating shaft 305. The lower end of the connecting block 304 is rotatably connected to a rotating shaft 701 through a rotating frame. A worm 702 is installed on the circumferential surface of the rotating shaft 701. The worm gear 7 meshes with the worm 702. A reset and correction column 703 is installed at the lower end of the movable plate 307. The reset and correction column 703 is in contact with the connecting block 304.

[0026] In one case of the embodiment of the present invention, when it is necessary to control the reset of the movable plate 307, through the action of the reset and correction column 703, a support point is provided, which can ensure the stability of the movable plate 307 after reset.

[0027] In practical application of the embodiment of the present invention, the rotating shaft 701 is rotated to drive the worm 702 to rotate. The worm 702 drives the worm gear 7 to rotate. The worm gear 7 can drive the rotating shaft 305 to rotate. The rotating shaft 305 can drive the connecting frame 306 to rotate. The connecting frame 306 drives the movable plate 307 to rotate an angle, thereby achieving the effect of controlling the angle adjustment of the steel pipe on the movable plate 307, facilitating the effect of splicing and welding the steel pipes at different angles.

[0028] As Figures 5-7 shown, as another preferred embodiment of the present invention, a gear 704 is rotatably connected in the reset and correction column 703. The first rack 705 and the second rack 706 slidably connected in the reset and correction column 703 are both meshed with the gear 704. A second spring 707 is installed between the first rack 705 and the reset and correction column 703. The mounting frame 708 installed at the upper end of the second rack 706 is slidably connected to the movable plate 307 and the reset and correction column 703. A limit tooth block 709 is installed at the upper end of the mounting frame 708. A limit tooth groove 7010 is opened on the circumferential surface of the driven shaft 309.

[0029] In the actual application of the embodiment of the present invention, when the movable plate 307 rotates, the lower end of the first rack 705 will disengage from the connecting block 304 at this time. Then, under the action of the second spring 707, the first rack 705 is driven to move downward. The first rack 705 drives 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 limit tooth block 709 to move upward, so that the limit tooth block 709 fits with the driven shaft 309. At the same time, through the cooperation of the limit tooth groove 7010, the driven shaft 309 can be locked, thereby avoiding the rotation of the driven shaft 309 and the driven wheel 3010. After the angle of the steel pipe on the movable plate 307 is adjusted, it can be avoided that the rotation of the steel pipe makes it difficult to position the connection position, and the stability during the connection of the steel pipes is improved.

[0030] As Figure 5 shown, as 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, and the angle pointer 801 corresponds to the angle groove 8.

[0031] In the actual application of the embodiment of the present invention, when the connecting frame 306 rotates, it will drive the angle pointer 801 to rotate. Then, through the cooperation of the angle groove 8, the angle of the movable plate 307 can be accurately adjusted, and the steel pipes can be spliced and fixed at different angles.

[0032] As Figure 1 、 4 、10 and 11 shown, as another preferred embodiment of the present invention, an electric push rod 9 is installed at 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, and the output end of the rotary motor 901 is fixedly connected to the rotating column 303.

[0033] In the actual application of the embodiment of the present invention, by controlling the operation of the electric push rod 9, the height positions 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 fixing plate 202. At the same time, when facing steel pipes of different diameters, adjustments can be made. Subsequently, after the angle of the steel pipe on the movable plate 307 is adjusted, when the steel pipe on the height plate is spliced with the steel pipe on the movable plate 307 at a predetermined angle, at this time, the rotary motor 901 can be controlled to rotate synchronously with the drive motor 6, driving the rotating column 303 to rotate synchronously with the drive wheel 205, so as to realize the rotation effect when the two steel pipes are relatively stationary, which is convenient for the staff to weld the steel pipes.
