Description

Technical Field

[0001] The utility model belongs to the technical field of welding equipment, in particular to a double-station arc welding workstation. Background Art

[0002] Welding robots are industrial robots that perform welding (including cutting and spraying). According to the definition of the International Organization for Standardization (ISO), industrial robots belong to standard welding robots. Industrial robots are multi-purpose, reprogrammable, automatically controlled manipulators with three or more programmable axes used in the field of industrial automation. In order to adapt to different uses, the mechanical interface of the last axis of the robot is usually a connecting flange that can be connected to different tools or end effectors. The welding robot is an industrial robot with a welding tongs or welding (cutting) gun installed on the end axis flange, so that it can perform welding, cutting or thermal spraying.

[0003] For example, a double-station arc welding workstation disclosed in announcement number CN221134438U includes a workstation platform, a support frame is fixedly installed on the upper surface of the workstation platform, a welding robot is installed on one side of the support frame, a rotating shaft is rotatably installed on the upper end of the support frame, a stepper motor is fixed at one end of the support frame, a first pillar and a second pillar are respectively fixed at both ends of the rotating shaft, and the first pillar and the second pillar are symmetrically arranged; the movable end of the first electric push rod is coaxially connected to the first driven disk, and the movable end of the second electric push rod is coaxially connected to the second driven disk. Through the above technical solution, a support frame is fixedly installed on the upper surface of the workstation platform to rotatably support the rotating shaft, and a stepper motor fixed at one end of the support frame controls the rotation of the rotating shaft. By setting two workstations, arc welding can be performed while loading and unloading, which shortens the loading and unloading cycle and improves work efficiency.

[0004] The above patent has two workstations. Although it can improve work efficiency, the existing workstations are limited in size. It is not convenient for welding robots to weld larger workpieces at one time. Moreover, welding work not only requires welding on the surface of the workpiece, but also on corners or other locations. The traditional welding method is that the welding robot does not change its position and loads and unloads the workpiece multiple times to ensure that all areas can be welded, which is inconvenient to operate. Utility Model Content

[0005] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a double-station arc welding workstation, which can increase the welding range of the welding robot, does not need to disassemble the workpiece, and has a large welding range.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is as follows: a double-station arc welding workstation, including an operating table mechanism and two welding robots arranged inside the operating table mechanism,

[0007] The operating table mechanism includes an operating table body;

[0008] A slide rail mechanism is fixedly installed on the operating table mechanism, and the slide rail mechanism includes a first slide rail fixedly installed on the upper end of the operating table body, and second slide rails are slidably installed on both sides of the first slide rail, the second slide rail is an arc structure, and third slide rails are arranged on both sides of the second slide rail;

[0009] An electric slider is fixedly installed at the lower end of the welding robot, and the electric slider is slidably installed in the first slide rail;

[0010] The lower end of the slide rail mechanism is provided with a sliding mechanism.

[0011] Preferably, a first slide groove is provided at the bottom of the operating table body, a second slide groove is provided at the lower end of the side wall of the operating table body, and a limit block is fixedly installed at one end of the operating table body.

[0012] Preferably, four groups of the third slide rails are provided, and the four groups of the third slide rails are fixedly installed in pairs on both sides of the second slide rail, and the third slide rail is slidably connected to one end of the first slide rail.

[0013] Preferably, the sliding mechanism comprises a cross bar fixedly mounted on the lower end of the second slide rail, first L-shaped plates are fixedly mounted on both sides of the cross bar, and the first L-shaped plate is also clamped and mounted on one side of the third slide rail.

[0014] Preferably, a push rod is fixedly mounted on one end of the cross bar, a limit sleeve is rotatably mounted on one end of the push rod, a rotation hole is formed on the limit sleeve, and the rotation hole is also slidably connected to the limit block.

[0015] Preferably, a second L-shaped plate is fixedly mounted on both ends of the cross bar, and the second L-shaped plate is slidably connected to the second sliding groove.

The welding robot of the device can electrically adjust the position, and a variety of slide rail forms can be switched arbitrarily, which increases the diversity of sliding, facilitates welding of welding positions of different sizes or angles, and improves work efficiency.

[0020] 2. The second slide rail and the third slide rail can be connected together through the cooperation of the cross bar and the first L-shaped plate. When the cross bar moves, the second slide rail and the third slide rail can be switched back and forth for easy adjustment.

[0021] 3. Through the second L-shaped plate and the second slide groove, the length of the second slide groove corresponds to the sliding distance of the second slide rail and the third slide rail, which is convenient for limiting the sliding of the cross bar and ensuring that the two are docked and will not be misaligned. At the same time, both ends of the cross bar are subjected to force at the same time, ensuring the stability of the sliding of the slide rail. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The utility model is further described below in conjunction with specific embodiments.

[0030] like Figure 1-Figure 4 As shown, a double-station arc welding workstation includes an operating table mechanism 1 and two welding robots 3 arranged inside the operating table mechanism 1. The two welding robots 3 are arranged to improve the welding efficiency.

[0031] The operating table mechanism 1 includes an operating table body 11 .

[0032] A slide rail mechanism 2 is fixedly installed on the operating table mechanism 1. The slide rail mechanism 2 includes a first slide rail 21 fixedly installed on the upper end of the operating table body 11. Second slide rails 22 are slidably installed on both sides of the first slide rail 21. The second slide rails 22 are arc-shaped structures.

[0033] An electric slider 31 is fixedly mounted on the lower end of the welding robot 3 , and the electric slider 31 is slidably mounted in the first slide rail 21 .

[0034] A sliding mechanism 5 is provided at the lower end of the slide rail mechanism 2 .

[0035] In the initial state, the second slide rails 22 are installed on both sides of the first slide rail 21. The welding robot 3 can be slidably installed in the first slide rail 21 and the second slide rail 22 through the electric slider 31, which increases the welding range of the welding robot 3. Since the second slide rail 22 is an arc structure, when the welding robot 3 slides to this point, the motion trajectory is an upward arc, which can further increase the welding height and length of the welding robot 3, thereby increasing the sliding diversity of the welding robot 3, which is convenient for welding larger workpieces.

[0036] A third slide rail 23 is provided on both sides of the second slide rail 22. Both the second slide rail 22 and the third slide rail 23 can slide to dock with the first slide rail 21. When the first slide rail 21 is docked with the second slide rail 22, the welding robot 3 slides to both sides in an arc structure. When the first slide rail 21 is docked with the third slide rail 23, the welding robot 3 slides to both sides in a straight structure. The length of the third slide rail 23 can be set arbitrarily, thereby further increasing the welding range of the device.

[0037] The welding robot 3 of the device can electrically adjust its position, and a variety of slide rail forms can be switched arbitrarily, which increases the diversity of sliding and facilitates welding at welding positions of different sizes or different angles.

[0038] like Figure 1-Figure 5 As shown, a first slide groove 12 is provided at the bottom of the operating table body 11 , a second slide groove 13 is provided at the lower end of the side wall of the operating table body 11 , and a limit block 14 is fixedly installed at one end of the operating table body 11 .

[0039] There are four groups of third slide rails 23, and the four groups of third slide rails 23 are fixedly installed on both sides of the second slide rail 22 in pairs. The third slide rail 23 is slidably connected to one end of the first slide rail 21, ensuring that the first slide rail 21 can be directly connected with the second slide rail 22 and the third slide rail 23 without affecting the sliding of the welding robot 3.

[0040] The sliding mechanism 5 includes a cross bar 51 fixedly mounted on the lower end of the second slide rail 22 , and first L-shaped plates 52 are fixedly mounted on both sides of the cross bar 51 . The first L-shaped plates 52 are also clamped and mounted on one side of the third slide rail 23 .

[0041] The second slide rail 22 and the third slide rail 23 can be connected together by the cooperation of the cross bar 51 and the first L-shaped plate 52. When the cross bar 51 moves, the second slide rail 22 and the third slide rail 23 can be switched back and forth for easy adjustment.

[0042] like Figure 2-Figure 5 As shown, a push rod 53 is fixedly mounted on one end of the cross bar 51 , and a limit sleeve 54 is rotatably mounted on one end of the push rod 53 . A rotation hole 55 is formed on the limit sleeve 54 , and the rotation hole 55 is also slidably connected to the limit block 14 .

[0043] Second L-shaped plates 56 are fixedly mounted on both ends of the crossbar 51 , and the second L-shaped plates 56 are slidably connected to the second sliding groove 13 .

[0044] In the initial state, the first slide rail 21 is docked with the second slide rail 22. When the tracks need to be switched, the cross bar 51 is pulled outward, the limit block 14 is disengaged from the rotating hole 55, and the second L-shaped plate 56 abuts against the groove wall of the second slide groove 13, so that one of the third slide rails 23 and the first slide rail 21 can be docked together for easy adjustment.

[0045] When it is necessary to dock the other third slide rail 23 with the first slide rail 21, rotate the limit sleeve 54 to make it misaligned with the limit block 14, and push the cross bar 51 forward so that the second L-shaped plate 56 contacts the other side wall of the second slide groove 13. At this time, the first slide rail 21 can be docked with the other third slide rail 23, which is easy to operate.

[0046] When the second slide rail 22 needs to be re-joined with the first slide rail 21 , the limiting sleeve 54 is rotated to allow the limiting block 14 to be re-inserted into the rotating hole 55 and slid until it contacts the operating table body 11 .

[0047] Through the second L-shaped plate 56 and the second slide groove 13, the length of the second slide groove 13 corresponds to the sliding distance of the second slide rail 22 and the third slide rail 23, which is convenient for limiting the sliding of the cross bar 51 and ensuring that the two are docked and will not be misaligned. At the same time, both ends of the cross bar 51 are subjected to force at the same time, ensuring the stability of the sliding of the slide rail.

[0048] like Figure 1and Figure 6 As shown, two fixing mechanisms 4 are further installed at the upper end of the operating table mechanism 1 . The fixing mechanisms 4 include two supporting plates 41 fixedly installed on the operating table body 11 , and a placement plate 42 is installed between the two supporting plates 41 .

[0049] A filter plate 43 is inlaid on the placement plate 42 , and a plurality of sets of fixing blocks 44 are fixedly mounted on both sides of the placement plate 42 .

[0050] The table top of the placement plate 42 is relatively large, which is convenient for placing relatively large workpieces. At the same time, the device is provided with a plurality of fixing blocks 44 for facilitating positioning.
