Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a welding device with a welding distance control structure. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials by heating, high temperature or high pressure. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasonic.

[0003] When welding different workpieces, in addition to the different welding forms, different devices are often used for welding when welding workpieces of different shapes.

[0004] In existing welding seam processing, the most common welding method is plane gap welding, in which the gap between two workpieces is welded after the two workpieces are joined together.

[0005] In the prior art, the welding methods for this type of welds are mostly manual welding, robotic arm welding, or welding using some special equipment. Among them, the quality of manual welding cannot be guaranteed, it is more dependent on the skills of the operator, and the efficiency is relatively low. Although robotic arm welding has a high degree of automation, it is expensive. Although the cost of special equipment is lower than that of robotic arms, when welding, corresponding fixtures or welding guns need to be assembled for workpieces of a certain size or model. This results in a relatively long time spent on replacing and debugging accessories each time different workpieces are processed, especially in adjusting the distance between the welding nozzle and the weld so that the welding nozzle can evenly weld the gap between the two workpieces during the welding process.

[0027] Embodiment 2:

[0028] Based on the above embodiments, Figure 2 As shown, the movable seat 8 includes a first servo motor 23, a sliding plate 24 and a fixed plate 25, a rack 26 is provided along the length direction of the cross beam 7, the sliding plate 24 is slidably provided on the cross beam 7, the fixed plate 25 is connected to the sliding plate 24, the lifting assembly is installed on the sliding plate 24, the first servo motor 23 is installed on the sliding plate 24, a gear 27 is sleeved on the output shaft of the first servo motor 23, and the gear 27 is meshed and connected with the rack 26. With the help of the sliding plate 24, the entire movable seat 8 can be installed on the cross beam 7, so that the movable seat 8 can move along the cross beam 7, and the first servo motor 23 is started during the movement, and the gear 27 is driven to rotate by the first servo motor 23, so that the sliding plate 24 is driven to move along the cross beam 7 by the cooperation of the gear 27 and the rack 26. By providing the fixed plate 25, it is convenient to install the welding gun 2 through the lifting assembly.

[0029] The upper and lower sides of the cross beam 7 are provided with slide rails 28 along the length direction thereof, and the upper and lower sides of the sliding plate 24 are respectively connected to the two slide rails 28 by sliding through two sets of sliding wheels 29. Through the cooperation of the slide rails 28 and the sliding wheels 29, the sliding plate 24 can be smoothly moved along the cross beam 7. At the same time, the two sets of sliding wheels 29 cooperate with the upper and lower slide rails 28, and can realize the sliding of the sliding plate 24 while fixing the entire sliding plate 24 on the cross beam 7, so that the sliding plate 24 can only move along the length direction of the cross beam 7 and will not fall off the cross beam 7.

[0030] Embodiment 3:

[0031] Based on the above embodiments, Figure 3 As shown, the lifting assembly includes an upper base plate 30, a lower base plate 31, a connecting plate 32, a sliding bar 33 and a sliding block 34. The upper and lower ends of the connecting plate 32 are respectively connected to the upper base plate 30 and the lower base plate 31, and the side is connected to the sliding plate 24. The upper and lower ends of the sliding bar 33 are respectively connected to the upper base plate 30 and the lower base plate 31. The sliding block 34 is slidably mounted on the sliding bar 33 through a sliding hole 35. The welding gun 2 is connected to the sliding block 34. A second servo motor 36 is installed on the upper side of the upper base plate 30. The output shaft of the second servo motor 36 is set downward and passes through the upper base plate 30. A first screw rod 37 is vertically connected below the upper base plate 30. The lower end of the first screw rod 37 is rotatably connected to the upper side of the lower base plate 31. A moving block 38 matching the first screw rod 37 is sleeved on the first screw rod 37, and the moving block 38 is connected to the sliding block 34. Before welding, since the two workpieces to be welded need to be fixed on the first clamping member 3 and the second clamping member 4 respectively, in order to avoid interference caused by the welding gun 2 being too close, the second servo motor 36 is rotated to drive the welding gun 2 to move upward to provide sufficient fixing space. After the fixing is completed, the second servo motor 36 is used to drive the welding gun 2 to move downward again, and it stops when the welding distance is reached, and then welding is performed. The moving block 38 is sleeved on the first screw rod 37, and a thread hole matching the first screw rod 37 is provided on the sleeve. When the second servo motor 36 rotates, it will drive the first screw rod 37 to rotate. When the first screw rod 37 rotates, since the sliding block 34 is connected to the moving block 38, the moving block 38 can only move up and down along the sliding bar 33 under the restriction of the sliding bar 33. In this way, when the first screw rod 37 rotates, the moving block 38 cannot rotate with the first screw rod 37, and can only drive the sliding block 34 to move up and down, thereby controlling the welding gun 2 to move up and down.

With this arrangement, when adjusting the position of the welding gun along the width direction of the processing table 1, the second screw rod 12 can be driven to rotate by rotating the rotating wheel 15, and the rotation of the second screw rod 12 can drive the adjustment block 4 to slide along the round rod 11, thereby driving the welding gun 2 to adjust its position.

[0034] The front baffle 9 is provided with a connecting rotating hole that runs through both sides. The end of the second screw rod 12 is rotatably set in the connecting rotating hole. A connecting rotating rod is provided in the middle of one side of the rotating wheel 15. The connecting rotating rod is coaxially connected to the second screw rod 12 in the connecting rotating hole.

[0035] Embodiment 5:

[0036] Based on the above embodiments, Figure 1 , 5 As shown, a fixed strip 16 is provided on the upper side of the processing table 1 along its length direction, an adjustment track 17 is provided in a recess on the upper side of the processing table 1 and is perpendicular to the fixed strip 16, and a locking block 18 is provided on the upper side of the processing table 1 and is slidably connected to the adjustment track 17. During welding, after the welds of the two workpieces are attached, one of the workpieces is attached to the fixed strip 16, and then the locking block 18 is slid along the adjustment track 17 to attach the locking block 18 to the other workpiece, thereby clamping the outer sides of the two workpieces, so that the weld position is tight.

[0037] The lower side of the locking block 18 is provided with an adjusting slider 19 that matches the adjusting track 17. The locking block 18 is provided with a locking threaded hole 21 that passes through the upper and lower sides. The inner thread of the locking threaded hole 21 is matched with a locking threaded rod 22, and the upper end of the locking threaded rod 22 is connected with a knob column 20. When the position of the locking block 18 needs to be adjusted, the locking threaded rod 22 is not in contact with the bottom of the adjusting track 17 by rotating the knob column 20, so that the locking block 18 can slide on the adjusting track 17. After the adjustment is completed, the locking block 18 can be fixed by rotating the knob column 20 so that the locking threaded rod 22 and the bottom of the adjusting track 17 are in contact with each other.
