Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1

[0032] Please refer to Figures 1-7, the present invention provides a technical solution: a butt welding device for a frame assembly, including a support frame 1, on which a guide rail assembly 2 is provided. The guide rail assembly 2 includes a first guide rail 21 and a second guide rail 22 provided on the support frame 1. A first slider seat 3 is cooperatively provided on the first guide rail 21, and a second slider seat 4 is cooperatively provided on the second guide rail 22; relying on the action of gravity, the first slider seat 3 can slide down along the first guide rail 21, and the second slider seat 4 can slide down along the second guide rail 22; specifically, the first guide rail 21 is composed of a first straight section 211, a second straight section 213, and a third straight section 215. The second straight section 213 is provided between the first straight section 211 and the third straight section 215. An arc transition section one 212 is provided between the second straight section 213 and the first straight section 211, and an arc transition section two 214 is provided between the second straight section 213 and the third straight section 215; the first straight section 211 and the third straight section 215 are both arranged parallel to the second guide rail 22, and the first straight section 211, the third straight section 215, and the second guide rail 22 are all inclined; at the same time, the first slider seat 3 and the second slider seat 4 respectively fix two workpieces to be butt welded (the workpieces are pipe fittings). Specifically, one of the workpieces is detachably provided on the first slider seat 3, and the other workpiece is detachably provided on the second slider seat 4.

[0033] A first fixing component 11 is provided on the support frame 1. The first fixing component 11 is close to the top end of the first straight section 211, and the first fixing component 11 is used to fix the first slider seat 3; specifically, the first fixing component 11 includes a first electromagnetic chuck 111 installed on the support frame 1. The first fixing component 11 further includes a first iron block 112 embedded in the first slider seat 3. The positions of the first electromagnetic chuck 111 and the first iron block 112 correspond. When the first electromagnetic chuck 111 is energized and the first iron block 112 approaches the first electromagnetic chuck 111, the first electromagnetic chuck 111 can adsorb the first magnetic block, thereby realizing the fixation of the first slider seat 3; when the first electromagnetic chuck 111 attracts the first iron block 112, it is used to install and fix the workpiece on the first slider seat 3; when the first electromagnetic chuck 111 is powered off, the first slider seat 3 carries the workpiece and slides down along the length direction of the first guide rail 21; at the same time, an elastic blocking component 5 is provided on the support frame 1. The elastic blocking component 5 is used to block the first slider seat 3 when the first slider seat 3 slides down and approaches the lower end of the third straight section 215, and the elastic blocking component 5 buffers the first slider seat 3.

[0034] A second fixing component 12 is also provided on the support frame 1, and the first fixing component 11 is close to the top end of the second guide rail 22; specifically, the second fixing component 12 includes a second electromagnetic chuck 121 and a second iron block 122. The second electromagnetic chuck 121 is installed on the support frame 1, and the second iron block 122 is embedded in the second slider seat 4; the second electromagnetic chuck 121 and the second iron block 122 are in corresponding positions. By attracting the second iron block 122 with the second electromagnetic chuck 121, the second slider seat 4 can be fixed. At this time, the workpiece is installed and fixed on the second slider seat 4; when the second electromagnetic chuck 121 is powered off, the second slider seat 4 can carry the workpiece and slide down along the length direction of the second guide rail 22; similarly, when the second slider seat 4 slides down close to the lower end of the second guide rail 22, the elastic blocking component 5 is also used to block the second slider seat 4, and the elastic blocking component 5 also buffers the second slider seat 4.

[0035] A grinding component 6 is provided on the support frame 1. During the downward sliding of the first slider seat 3 and the second slider seat 4, the grinding component 6 grinds the welding positions of the two workpieces to be welded respectively, which is used to improve the subsequent welding quality; specifically, the grinding component 6 includes a support 61 installed on the support frame 1. A grinding roller 63 is installed on the support 61, and the grinding roller 63 is movably connected to the support 61 through a bearing; a driving motor 62 is installed on the support 61, and the output shaft of the driving motor 62 is fixedly connected to one end of the grinding roller 63, and the output shaft of the driving motor 62 and the grinding roller 63 are coaxial. By the driving motor 62, the grinding roller 63 can be driven to rotate; the outer wall of the grinding roller 63 is adapted to the welding part of the workpiece fixed by the first slider seat 3, and the axis direction of the grinding roller 63 is parallel to the length direction of the first straight section 211. During the downward sliding of the first slider seat 3, the welding part of the workpiece fixed by the first slider seat 3 contacts the outer wall of the grinding roller 63, and the rotating grinding roller 63 performs good grinding on the welding part of the workpiece; due to the use of the rotary grinding method, on the one hand, the influence of the downward sliding of the first slider seat 3 is reduced, and on the other hand, it helps the debris after grinding to be thrown out following the rotation of the grinding roller 63.

[0036] The grinding component 6 further includes a fixing seat 64 fixed on the support frame 1. An arc-shaped grinding plate 65 is provided at the bottom of the fixing seat 64. The arc-shaped grinding plate 65 is adapted to the pipe fitting corresponding to the welding part of the workpiece fixed by the second slider seat 4. Specifically, when the workpiece is fixed on the second slider seat 4, the pipe fitting corresponding to the welding part of the workpiece is coaxial with the arc-shaped grinding plate 65, and during the downward sliding of the second slider seat 4, the outer wall of the pipe fitting corresponding to the welding part of the workpiece is ground by the arc-shaped grinding plate 65.

[0037] To facilitate the cleaning of the debris generated after two workpieces are polished by the polishing assembly 6, a chip blowing assembly 7 is provided on the support frame 1. The chip blowing assembly 7 includes a first air duct 71 and a second air duct 73, and both the first air duct 71 and the second air duct 73 are provided on the support frame 1. One ends of the first air duct 71 and the second air duct 73 are respectively provided with a first nozzle 72 and a second nozzle 74. The first nozzle 72 is inclined upward and is used to blow away the debris generated after the workpiece fixed by the first slider seat 3 is polished. The second nozzle 74 is used to blow away the debris generated after the workpiece fixed by the second slider seat 4 is polished. In addition, the ends of the first air duct 71 away from the first nozzle 72 and the second air duct 73 away from the second nozzle 74 are both connected to an external pressure air source (such as a device like an air pump), so as to realize the air flow ejected from the first nozzle 72 and the second nozzle 74.

[0038] Meanwhile, a detection assembly 8 is also provided on the support frame 1. The detection assembly 8 is used to detect the parts of the workpieces to be welded after the chip blowing assembly 7 cleans the debris. Specifically, the detection assembly 8 can be used to detect the debris on the parts of the workpieces to be welded. If a certain amount of debris is detected on any part of the workpieces to be welded (a small amount of debris hardly affects the subsequent welding quality), the debris can be blown away again manually or by an external manipulator, so as to avoid affecting the subsequent welding quality. And when the first slider seat 3 and the second slider seat 4 slide down and are supported by the elastic blocking assembly 5, at this time, the parts of the two workpieces to be welded just correspond to the detection assembly 8, which helps the detection of the detection assembly 8.

[0039] In this embodiment, when the first slider base 3 is located on the first straight segment 211, the second straight segment 213, the first arc transition segment 212 or the second arc transition segment 214, the workpiece part on the first slider base 3 contacts the workpiece on the second slider base 4; when the first slider base 3 moves to the third straight segment 215, the second slider base 4 is located on the second guide rail 22, and when the welding positions of the two workpieces correspond to each other, there is a small gap between the welding positions of the two workpieces, which can be set to 1-3 mm, and it will not affect the welding between the two workpieces. The set spacing is used to prevent friction between the two workpieces; for the convenience of alignment during welding, an adsorption assembly 9 is also provided. After the elastic blocking assembly 5 blocks the first slider base 3 and the second slider base 4, the positions of the first slider base 3 and the second slider base 4 are fixed by the adsorption assembly 9. At this time, the welding parts of the two workpieces just correspond to each other, so as to facilitate the welding of the workpieces by an external welding manipulator or manual means; at the same time, the adsorption assembly 9 can release the fixation of the first slider base 3 and the second slider base 4. After the butt welding of the two workpieces is completed, the adsorption assembly 9 releases the fixation of the first slider base 3 and the second slider base 4. At this time, the elastic blocking assembly 5 drives the first slider base 3 and the second slider base 4 to move upward, and makes the welding position correspond to the detection assembly 8 again. At this time, it is convenient for the detection assembly 8 to detect the welding quality, specifically, whether the dimensions, surface defects, etc. meet the requirements. For the detected surface defects, subsequent repair or other processing can be facilitated.

[0040] Specifically, the elastic blocking assembly 5 includes a fixed frame 51 arranged on the support frame 1. Two guide sliders 52 are embedded in the fixed frame 51, and the two guide sliders 52 are arranged in parallel; the axial directions of the two guide sliders 52 are parallel to the length direction of the second guide rail 22; the elastic blocking assembly 5 further includes two slide rods 53. The two slide rods 53 respectively pass through the two guide sliders 52, and the slide rods 53 are adapted to the guide sliders 52, that is, the length direction of the slide rods 53 is parallel to the length direction of the second guide rail 22; support blocks 54 are arranged at the upper ends of the slide rods 53, and the two support blocks 54 are respectively used to support and block the first slider base 3 and the second slider base 4; retaining rings 56 are respectively fixedly sleeved on the outer parts of each slide rod 53, and a spring 55 is arranged between each retaining ring 56 and the fixed frame 51, and the two springs 55 are respectively sleeved on the outer parts of the two slide rods 53; through the cooperation of the slide rods 53 and the guide sliders 52, the slide rods 53 can move along their length directions. By arranging the springs 55, when the first slider base 3 or the second slider base 4 touches the corresponding support block 54, it is convenient to cause the compression deformation of the springs 55, so as to realize the buffering effect on the first slider base 3 and the second slider base 4. And after the first slider base 3 and the second slider base 4 are stable, through the action of the springs 55, the support for the first slider base 3 and the second slider base 4 is realized. At this time, the welding parts of the two workpieces correspond to the detection assembly 8.

[0041] The adsorption assembly 9 includes a third iron block 92 embedded in the first slider seat 3 and a fourth iron block 94 embedded in the second slider seat 4; it also includes a third electromagnetic chuck 91 and a fourth electromagnetic chuck 93 installed on the fixed frame 51. The third electromagnetic chuck 91 is used to adsorb the third iron block 92, and the fourth electromagnetic chuck 93 is used to adsorb the fourth iron block 94; when the first slider seat 3 and the second slider seat 4 are supported and blocked by the two support blocks 54, the third electromagnetic chuck 91 and the fourth electromagnetic chuck 93 are energized, and the third iron block 92 can be adsorbed on the third electromagnetic chuck 91, and the fourth iron block 94 can be adsorbed on the fourth electromagnetic chuck 93. At this time, the spring 55 is compressed; at this time, the welding positions of the two workpieces deviate from the detection assembly 8, and the welding positions of the two workpieces just correspond, which helps to perform welding processing by means of an external manipulator or manual work, etc., and reduces or avoids the influence on the welding operation; after the welding is completed, the third electromagnetic chuck 91 and the fourth electromagnetic chuck 93 are powered off, and under the action of the spring 55, the first slider seat 3 and the second slider seat 4 are pushed upward, and the welding positions of the workpieces are made to correspond to the detection assembly 8 again; of course, after the welding is processed well, the deviation between the overall after welding and the gravity of the two workpieces before welding is not large, and at this time, the detection angle of the detection assembly 8 can still detect the welding position; after the welding is completed, the entire welded workpiece can be disassembled from the first slider seat 3 and the second slider seat 4, and the first slider seat 3 and the second slider seat 4 are pushed upward, and by energizing the first electromagnetic chuck 111 and the second electromagnetic chuck 121, the first iron block 112 and the second iron block 122 are re-adsorbed, and the installation and fixation of the next group of workpieces can be carried out.

[0042] In this embodiment, the first slider seat 3 and the second slider seat 4 are used to drive the workpiece to slide down, and the welding position of the workpiece is polished during the sliding process of the workpiece, which helps to improve the welding quality; at the same time, by setting the elastic blocking assembly 5, it can not only support and buffer the first slider seat 3 and the second slider seat 4, but also drive the welding position of the workpiece to correspond to the detection assembly 8 again after the welding is completed; in addition, the detection assembly 8 is used for detection before and after welding, which helps to ensure the welding quality, and can detect the welding quality in time after the welding is completed without taking out the workpiece, which helps to improve the detection efficiency.

The two industrial cameras 81 are respectively used to detect and identify both sides of the welding position of the workpiece; of course, the detection assembly 8 can also adopt other existing technologies, which will not be elaborated here.

[0046] Please refer to Figure 9 and Figure 10 , based on the first embodiment, both the first slider seat 3 and the second slider seat 4 include sliders. The cross-sectional structures of the first guide rail 21 and the second guide rail 22 are the same, and the sliders are adapted to the first guide rail 21 and the second guide rail 22.
