Detailed Description
The present invention will be described in detail with reference to the drawings, and reference is made to fig. 1 to 20, which illustrate some preferred embodiments of the present invention.
The fully automated welding system of the present invention is used to weld a pipe 800 to one end of a pipe 700, as shown in fig. 18, 19, and 20, wherein the pipe may be a large or small end 801, an extension pipe 802, an embedded pipe 803, or other type of component that needs to be welded to the end of the pipe 700 to accommodate a specific application, and is not specifically disclosed herein. In a specific welding process, the weld seam B is a generally annular seam, which may be a butt seam as shown in fig. 18, an external corner seam as shown in fig. 19, an internal corner seam as shown in fig. 20, or any other type of annular seam, and is not further developed herein.
As shown in fig. 1, the full-automatic welding system according to the present invention includes: work or material rest 100, transfer device 200, headstock 300, tailstock 400, and welding device 500.
As shown in fig. 3 and 4, the rack 100 has a bearing surface on which the pipe 700 rolls in the first direction. In this embodiment, the material rack 100 includes three material rack monomers arranged in parallel at intervals, namely a first material rack monomer 101, a second material rack monomer 102 and a third material rack monomer 103; the first material frame unit 101, the second material frame unit 102 and the third material frame unit 103 are respectively provided with a supporting beam 11 which is positioned at the top and extends towards the first direction, and the top surfaces of the supporting beams 11 jointly form a bearing surface for the pipeline 700 to roll towards the first direction. In other embodiments of the present invention, the cartridge 100 may be constructed from other numbers of cartridge cells.
In the present invention, the conduit 700, which is typically placed on the carrying surface of the rack 100, has a tendency to move spontaneously in a first direction, which tendency can be provided by external power. As a preferred embodiment of the present invention, the tendency of spontaneous movement is provided by the gravitational potential energy of the pipe 700, and in this embodiment, the bearing surface is in a downward slope shape in the first direction, that is, the top surface of the supporting beam 11 forms a slope for the pipe 700 to automatically roll.
As further shown in connection with fig. 4, 5 and 8, the carrying surface of the rack 100 has a working position 111, and the rack 100 further has a stop mechanism 12 for preventing the pipe 700 from rolling further to position the pipe 700 in the working position 111. I.e. when the pipe 700 is rolled over the bearing surface, it can be blocked by the stop mechanism 12 when it is rolled to the working position 111, thereby avoiding further rolling along the bearing surface.
As shown in fig. 1, 2, 11 and 12, the transfer device 200 of the present invention has a transfer wheel 21 for lifting up the pipe 700 at the working position 111 and transferring the pipe 700 in the second direction. The second direction is perpendicular to the first direction, and in this embodiment, the first direction is consistent with the length direction of the supporting beam 11, and the second direction is consistent with the distribution direction of the three material frame units.
Referring to fig. 1 and 15, the head 300 is disposed on one side of the material holder 100 in the second direction, the head 100 has a chuck 31 rotatably disposed, the chuck 31 is used for fixing the pipe 700 transferred to the head 100 by the transfer device 200, and the pipe 700 can be driven to rotate around the axis of the pipe 700 itself, and the chuck 31 has a through hole (not shown) through which the pipe 700 passes to expose an end portion thereof to a side of the head 300 away from the material holder 100. As shown in fig. 1 and 2, the pipe 700 rolled to the working position 111 may approach or separate from the headstock 100 in the second direction by the transfer of the transfer wheel 21 of the transfer device 200; since the end of the pipe 700 after passing through the chuck 31 may be exposed to the side of the head 300 remote from the work stack 100, a welding work between the pipe 700 and the pipe 800 may be performed at the side of the head 300 remote from the work stack 100, i.e., the side of the head 300 remote from the work stack 100 may constitute a welding station for performing the welding work.
As shown in connection with fig. 1 and 16, the tailstock 400 of the present invention is disposed on a side of the headstock 300 away from the work piece 100, and the side of the tailstock 400 facing the headstock 300 has a chuck 41 for carrying a pipe 800. With this arrangement, the tube 800 carried by the chuck 41 of the tailstock 400 can be assembled with one end of the pipe 700 secured by the headstock 300 prior to welding.
Referring to fig. 15 and 16, a welding apparatus 500 of the present invention includes a welding gun 52 for welding and fixing a pipe 800 to a pipe 700.
Based on the full-automatic welding system provided by the invention, in the process of welding the pipeline 700 and other pipe fittings 800, the full-automatic loading and unloading, clamping, welding and other working procedures of the pipeline 700 can be realized, excessive participation of manpower can be avoided, the efficiency of pipeline welding is effectively improved, the basic requirement of high-efficiency production of the current enterprise is met, and the standardized welding process can also ensure that the welding quality has higher reproducibility.
For a better understanding of the present invention, the following will describe the present invention in more detail:
as shown in fig. 1 and 13, the full-automatic welding system according to the present invention further includes an auxiliary rotating device 600, where the auxiliary rotating device 600 includes at least one auxiliary rotating support frame. In this embodiment, the auxiliary rotating device 600 includes three auxiliary rotating support frames, namely a first auxiliary rotating support frame 601, a second auxiliary rotating support frame 602 and a third auxiliary rotating support frame 603, which are distributed at intervals in the second direction.
As shown in fig. 14, each auxiliary rotating support frame has a roller set 61 that is disposed on the top to rotate the support pipe 700 when the chuck 31 drives the pipe 700 to rotate, and the roller set 61 has a supporting state in which the rollers of the roller set 61 are raised beyond the bearing surface to abut against the outer wall of the pipe 700, and a non-supporting state in which the top of the roller set 61 is lowered below the bearing surface.
Specifically, the roller set 61 includes a first roller 611 and a second roller 612 that are disposed in parallel in a first direction, and rotation axes of the first roller 611 and the second roller 612 extend along a second direction; as the pipe 700 rotates, the first roller 611 and the second roller 612 together form a support for the pipe and can rotate synchronously with the pipe 700.
In addition, it is easy to understand that, in the first direction, the position of the auxiliary rotating support frame is consistent with the working position 111, so that after the conveying device 200 conveys the pipe 700 to the headstock 300 and is fixed by the chuck 31, the roller sets 61 of the first auxiliary rotating support frame 601, the second auxiliary rotating support frame 602 and the third auxiliary rotating support frame 603 can jointly support the pipe 700 in the rotating process with the chuck 31 through ascending.
Considering the stability of the first auxiliary rotating support frame 601, the second auxiliary rotating support frame 602 and the third auxiliary rotating support frame 603 in supporting the pipe, the three auxiliary rotating support frames are distributed at intervals in the second direction, and in this embodiment, the three auxiliary rotating support frames and the three material frame monomers are distributed in a staggered manner.
In more detail, as shown in reference 14, the auxiliary rotating support frame according to the present embodiment further includes an auxiliary rotating base 62, a first lifting table 610 lifting and lowering the top of the auxiliary rotating base 62, and a first motor 63 driving the first lifting table 610 to perform lifting and lowering operations, and the roller set 61 is rotatably disposed on the first lifting table 610.
As further shown in fig. 1 and 11, in the present invention, in the second direction, the conveying device 200 includes at least two conveying support frames that are spaced apart. In the embodiment, the conveying device 200 includes three conveying support frames, i.e. a first conveying support frame 201, a second conveying support frame 202 and a third conveying support frame 203, which are distributed at intervals in the second direction.
As shown in fig. 14, each of the transfer frames has a transfer wheel 21 disposed on the top in a lifting manner, and the transfer wheel 21 has a transfer state of lifting up the pipe 700 located on the working position 111 beyond the carrying surface and a non-transfer state of lowering to a position where the top of the transfer wheel 21 is lower than the carrying surface.
The conveying support frame according to the present embodiment further includes a conveying support base 22, a second lifting platform 210 disposed on the top of the conveying support base 22, and a second motor 23 for driving the second lifting platform 210 to lift, wherein the conveying wheel 21 is rotatably disposed on the second lifting platform 210, and at least one conveying wheel 21 of the plurality of conveying support frames is further connected with a third motor 24 for driving the conveying wheel to rotate.
As will be readily appreciated, in order to enable stable transfer of the conduit 700 by the plurality of transfer shelves, the three transfer shelves are spaced apart in the second direction. In this embodiment, referring to fig. 10, three conveying support frames and three auxiliary rotating support frames are staggered. Further referring to fig. 4, in this embodiment, a conveying support frame is disposed on one of two sides of each material frame, and an auxiliary rotating support frame is disposed on the other side. Preferably, referring to fig. 12, the transfer wheel 21 according to the present invention has a dumbbell shape with a thin middle and thick ends.
During operation of the full automatic welding system, the transmission device 200 and the auxiliary rotating device 600 are matched in the following manner: the pipe 700 to be welded at the working position 111 of the material frame 100 is jacked up by the conveying device 200 and conveyed to the through hole of which one end is inserted into the chuck 31; after the chuck 31 fixes the pipe 700, the roller set 61 on the auxiliary rotating device 600 is lifted; after the roller group 61 of the auxiliary rotating device 600 supports the pipe 700, the transfer wheel 21 on the transfer device 200 descends. Thus, when the chuck 31 fixes the pipe 700 and drives the pipe 700 to rotate, the transfer wheel 21 does not affect the rotation of the pipe 700, and the roller set 61 can form a rotation support for the pipe 700, so as to complete the rotation action when welding between the pipe 700 and the pipe 800. In the present invention, after the welding between the pipe 700 and the pipe 800 is completed, the pipe 700 welded with the pipe 800 can be transferred to the bearing surface of the material rack 100 again by the cooperation of the transmission device 200 and the auxiliary rotation device 600, so as to perform the next step.
As shown in fig. 8 and 9, the stop mechanism 12 of the present embodiment includes a stop plate 121 rotatably provided and a first cylinder 122 for driving the stop plate 121 to rotate; in this embodiment, each material rack unit may be provided with a stop mechanism 12, and the telescopic rod 1220 of the first cylinder 122 is connected to the baffle 121, so that the rotation control of the baffle 121 can be achieved through the telescopic control of the telescopic rod 1220.
As shown in fig. 8, the baffle 121 has a stop state that rotates to a position where a part protrudes upward beyond the bearing surface to stop the pipe 700 from rolling, and when the baffle 121 is in the stop state, the pipe 700 can be positioned at the working position 111, so that the lifting of the pipe at the working position 111 and the conveying in the second direction can be smoothly realized by the conveying device 200. As shown in fig. 9, the damper 121 according to the present embodiment further has a non-stop state rotated to be located entirely below the bearing surface, and when the damper 121 is in the non-stop state, the pipe 700 located at the working position 111 can continue to roll in the first direction on the bearing surface.
The carrying surface in this embodiment also has a loading area (not identified in the figure) for providing the pipeline 700 to the working station 111. Referring to fig. 5 and 6, a stop 13 for blocking the pipe 700 in the feeding area from rolling along the bearing surface toward the working position 111 is fixed on one side of the feeding area near the working position 111 in this embodiment, that is, the pipe 700 in the feeding area cannot roll from the bearing surface to the working position directly under the blocking action of the stop 13. To achieve transfer of the in-loading-area pipe 700 to the working site 111, the rack 100 according to the present invention further has a loading mechanism 14 for lifting up the in-loading-area pipe 700 to transfer the pipe 700 to the working site 111. In this embodiment, each material rack unit is provided with a feeding mechanism 14 and a stop 13.
The feeding mechanism 14 in this embodiment includes a feeding rod 141 rotatably disposed and a second cylinder 142 for driving the feeding rod 141 to rotate, where a telescopic rod 1420 of the second cylinder 142 is connected to the feeding rod 141, so that rotation control of the feeding rod 141 can be achieved through telescopic control of the telescopic rod 1420.
Further, as shown in fig. 6 and 7, the feeding rod 141 in this embodiment has a feeding state rotated to a position where a part protrudes upwards beyond the bearing surface to jack up the pipe 700 near the position where the stop block 13 is located in the feeding area, when the feeding rod 141 is in the feeding state, the bottom of the pipe 700 jacked by the feeding rod 141 is not lower than the top height of the stop block 13, and a slope 1410 for the pipe 700 to roll toward the working position 111 is formed on one side of the feeding rod 141 for jacking up the pipe 700; that is, the pipe 700 can spontaneously roll to the working position 111 through the slope on the feeding rod 141 after being jacked up by the feeding rod 141. The feeding rod 141 in this embodiment also has a non-feeding state in which it is rotated to be completely below the carrying surface, and when the feeding rod is in the non-feeding state, the pipe 700 in the feeding area is restricted by the stopper 13 and cannot enter the working position.
It can be understood that a plurality of pipes 700 can be accommodated in the feeding area in this embodiment, and the feeding rod 141 can jack up only one pipe 700 at a time, so that only one pipe 700 can enter the working position at a time, and smooth operation of the full-automatic welding system can be ensured.

In particular, in the present embodiment, the chuck 41 clamps the pipe 800 by using a plurality of jaws 410 to carry the pipe 800, and the distance between each jaw 410 and the rotation axis of the chuck 41 is adjustable.
In order to provide a proper welding position of the pipe 800 clamped by the chuck 41 with respect to the end of the pipe 700, the tailstock 400 in this embodiment further has an X-axis adjusting mechanism that adjusts the position of the chuck 41 in the second direction, a Y-axis adjusting mechanism that adjusts the position of the chuck in the first direction, and a Z-axis adjusting mechanism that adjusts the position of the chuck in the up-down direction.
