Description

Technical Field

[0001] The present invention belongs to the technical field of welding processing, and in particular relates to a multi-axis linkage welding processing device. Background Art

[0002] During the tank body coil welding process, the steel plate needs to be coiled into a cylindrical component first and then welded. The current processing method is to use some simple coiling models and manually operate the coiling, which is labor-intensive, inefficient, and has poor coiling quality. In addition, there are many unsafe factors. Especially when the steel plate is thick, manual operation is very difficult and cannot meet the production needs at all.

[0003] The Chinese patent with authorization announcement number CN204108551U discloses a tank body plate rolling welding device, which includes a rolling frame, a welding assembly arranged above the rolling frame, and a rolling assembly arranged below the rolling frame; the rolling assembly includes: an upper roller; a middle roller, the middle roller is located directly below the upper roller, and the two ends of the middle roller are supported and fixed on the rolling frame by a middle hydraulic rod, and the middle roller is driven to rise and fall by the middle hydraulic rod; a lower front roller, the lower front roller is arranged at the front side of the middle roller, and the two ends of the lower front roller are also provided with a front hydraulic rod that drives the lower front roller to close or separate from the upper roller; a lower rear roller, the lower rear roller is arranged at the rear side of the middle roller, and the two ends of the lower rear roller are hinged to the rolling frame through a rear hinged rod, and the two ends of the lower rear roller are also provided with a rear hydraulic rod that drives the lower rear roller to close or separate from the upper roller; the welding assembly is used to weld the front and rear ends of the rolled steel plate to close into a steel ring.

[0004] However, this technical solution still has at least the following drawbacks: the positioning of the weld seam is not precise enough, and manual welding is still required during welding. This operation is time-consuming and labor-intensive for large tanks. Furthermore, the tank remains on the plate rolling machine during welding, preventing the plate rolling machine from continuing to roll the plate during welding. In view of these drawbacks, the present invention is proposed. Summary of the Invention

The following embodiments are used to illustrate the present invention.

[0051] Example 1:

[0065] The first pushing mechanism includes a first electric track 100 and a first electric slide 101. A lever 102 is fixedly mounted on the bottom of the first electric slide 101. The position of the first electric slide 101 corresponds to the position of the baffle 214. In this arrangement, when the plate rolling machine 103 is in operation, the working roller 104 always rotates at a constant speed.

[0066] Example 3:

[0067] A multi-axis linkage welding processing device further includes a processor, the processor is configured with a control system for controlling a welding machine 503 to weld a plate, the control system includes a collection unit, a moving unit, and a welding unit;

[0068] The moving unit controls the moving module to move, so as to drive the plate to move;

[0069] The acquisition unit is used to obtain the gap position information of the plate, and the gap represents the gap formed at the two ends of the plate after curling;

[0070] The welding unit is used to control the welding module to weld the plates.

[0071] The mobile unit includes a position control strategy, which includes obtaining the working status of the plate rolling machine 103, generating a removal instruction when the plate rolling machine 103 completes the plate rolling work, executing a position control program based on the removal instruction, and generating a welding instruction after executing the position control program. The position control strategy also includes setting a designated point, which represents the point at which the center of the plate is aligned with the rotation center of the rotating mechanism when the plate moves to the top of the rotating mechanism;

[0072] The position control program indicates that the first electric slide 101 moves to a designated position and resets after moving to the designated position. After the first electric slide 101 resets, it drives the rotating mechanism to rotate ninety degrees.

[0073] The acquisition unit includes a gap positioning strategy, which includes obtaining the length of the plate, and the gap positioning strategy also includes configuring an initial state and a final state for the position sensor 105. The initial state represents the state when the position sensor 105 does not detect the plate, and the final state represents the state when the position sensor 105 detects the plate. The gap positioning strategy also includes generating a turn instruction when the position sensor 105 is converted from a final state to an initial state, and controlling the plate rolling machine 103 to work in reverse based on the turn instruction. The gap positioning strategy also includes obtaining the interval time between the two turn instructions generated first, and the turn instruction generated by the plate rolling machine 103 when the plate rolling is completed, and controlling the plate rolling machine 103 to continue working based on the turn instruction, and the working time is equal to half of the interval time, and the working time of the working roller 104 is driven by controlling the plate rolling machine 103 to be half of the interval time, so that when the plate rolling machine 103 stops again, the center of the circumference of the plate is located below the working roller 104, and at this time, the two ends of the plate are located above the working roller 104 after curling;

[0074] The acquisition unit also includes a path planning strategy, which includes obtaining the position corresponding to the central axis of the working roller 104 of the plate rolling machine 103 and establishing a plane rectangular coordinate system based on the center position of the central axis. The path planning strategy also includes obtaining the initial coordinates of the two endpoints of the central axis based on the plane rectangular coordinate system, and obtaining the displacement distance of the first electric slide 101 and the rotation angle of the rotating mechanism, and obtaining the corresponding final coordinates based on the two initial coordinates, and generating a straight line equation based on the two final coordinates.

[0075] The plane rectangular coordinate system takes the center point of the central axis as the origin and the direction of the center position of the rotating mechanism as the x direction.

[0076] The welding unit includes a path execution strategy, which includes obtaining a straight line equation generated by a path planning strategy and causing the welding machine 503 to control the movement of the main robot arm 504 and the auxiliary robot arm 505 based on the straight line equation so that the movement path of the welding gun 506 coincides with the straight line corresponding to the straight line equation;

[0077] The welding unit also includes a gap alignment strategy, which includes executing an alignment program when a welding instruction is obtained, and generating a start instruction after the alignment program is executed. The alignment program indicates that the second electric slide 208 moves and operates the cylinder 303 after the movement is completed.

[0078] The gap alignment strategy also includes obtaining the position of the gap through a visual sensor and causing the welding machine 503 to adjust the position of the welding gun 506 based on the position of the gap;

[0079] The welding unit also includes a spot welding execution strategy, which includes setting symmetrically distributed welding points on the movement path of the welding gun 506, and the positions of the welding points are located between the alignment mechanisms on both sides. The spot welding execution strategy also includes controlling the welding gun 506 to spot weld the welding points when a start instruction is obtained, and generating a full weld instruction when the spot welding is completed;

[0080] The welding unit also includes a full welding execution strategy, which includes controlling the second electric slide 208 to move and reset when a full welding instruction is obtained, and controlling the welding gun 506 to fully weld the gap along the moving path after the second electric slide 208 is reset.

[0081] The implementation principle of the multi-axis linkage welding processing device of this embodiment is as follows: during operation, the plate is rolled by the plate rolling machine 103. When the plate rolling machine 103 completes the rolling work, the first electric slide 101 moves and drives the shifting rod 102 to move. The shifting rod 102 drives the plate to move during the movement. At this time, the plate is formed into a cylindrical shape under the action of the plate rolling machine 103. The shifting rod 102 pushes the plate to move onto the support seat 301.

[0082] When the lever 102 is moved, the second electric slide 208 drives the clamping rod 209 and the clamping block 210 to move. During the movement of the clamping rod 209, it abuts against the guide plate 207 and, under the action of the guide plate 207, drives the clamping block 210 to clamp the gap of the plate. At this time, the oil cylinder 303 works and drives the limit rod 302 to rotate and clamp the plate, thereby closing the gap of the plate.

[0083] After the plates are combined, the welding machine 503 drives the welding gun 506 to move through the main robot arm 504 and the auxiliary robot arm 505. The movement path of the welding gun 506 is controlled by detecting the gap, so that the welding gun 506 performs a spot welding operation on the plates. After spot welding, the gaps of the plates remain connected. At this time, the second electric slide 208 is reset to disengage the clamping block 210 from the plates, and the welding gun 506 can then perform a full welding operation on the plates.

[0084] When the first electric slide 101 moves, it resists the baffle 214 and drives the second moving mechanism to move through the baffle 214, thereby preventing the second moving mechanism from hindering the movement of the first electric slide 101. At the same time, the second moving mechanism drives the connecting plate 400 to move, and the connecting plate 400 drives the slider 403 to move through the push rod 402. The slider 403 drives the baffle 511 to move through the limit plate 404, and then drives the cam 508 to rotate through the rocker rod 509. The rotation of the cam 508 causes the mounting plate 502 to descend, and then causes the welding machine 503 to descend as a whole, preventing the second moving mechanism from colliding with the welding machine 503 while being pushed by the first electric slide 101.

[0085] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
