Description
Technical Field
[0001] This utility model belongs to the field of welding torch support technology, specifically a novel welding torch fixing support device. Background Technology
[0002] A welding torch is the part that performs the welding operation during the welding process; it is a tool used for gas welding. The welding torch is one of the main pieces of equipment for hot air welding, and it consists of a heating element, a nozzle, etc. According to its structure, it is divided into gas welding torches, electric welding torches, high-speed welding torches, and automatic welding torches.
[0003] A patent with publication number CN106736102A discloses a novel welding torch fixing support device, including a rear fixing clamp plate and a front fixing clamp plate for the welding torch. A clamping bolt is connected to the rear fixing clamp plate, and a fine-adjustment bolt is connected to the lower end of the front fixing clamp plate. A sliding plate is provided on the front fixing clamp plate, and a slide rail is provided on the sliding plate. A clamping slider is provided on the slide rail, and a shim is provided between the clamping slider and the slide rail. The beneficial effects of this invention are that the fixing support device can fix both the front and rear of the welding torch, ensuring that the welding torch does not deviate. When it is necessary to adjust the angle and position of the welding torch, the position of the welding torch is adjusted by the slide rail on the sliding plate. When the welding torch position is fixed, the angle is finely adjusted using the fine-adjustment bolt provided on the front fixing clamp plate. This fixing support device has good operability and high welding accuracy.
[0004] Currently, existing welding torches require employees to maintain a specific posture when welding steel, limiting the height and position of the torch and moving the torch and body slowly along the gaps in the steel to weld them. However, maintaining the same posture for a long time puts a significant strain on the body. Furthermore, to reduce light stimulation during welding, a light shield is used to block the eyes, making it difficult for employees to control the height, angle, and direction of the torch. Novice employees are prone to making welding errors.
[0005] Therefore, a novel welding torch fixing support device is proposed to address the above problems. Utility Model Content
[0006] To overcome the shortcomings of existing technologies and solve the above-mentioned problems, a novel welding torch fixing support device is proposed.
[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A novel welding torch fixing support device of this utility model includes a support frame and two sets of iron plates movably overlapping the outer surface of the bottom of the support frame. An arc-shaped limiting groove is formed on the top surface of the support frame and on the inner walls of both sides. A second motor is fixedly installed on one side surface of the support frame. A threaded rod is fixedly connected to the output end of the second motor and movably overlapping the top surface of the support frame. A threaded slider is threadedly movably sleeved on the outer surface of the threaded rod. An arc-shaped slider is fixedly connected to the outer surface of the threaded slider. The inner wall of the arc-shaped slider movably overlaps the outer surface of the support frame and the arc-shaped limiting groove. A snap-fit sleeve is provided on the outer surface of the arc-shaped slider. An arc welder is movably sleeved on the inner wall of the snap-fit sleeve. A limiting strip is provided on the inner wall of the snap-fit sleeve. A butt-fit limiting groove is formed on the outer surface of the arc welder. The output end of the butt-fit limiting groove movably overlaps the gap between the two sets of iron plates.
[0008] Preferably, an overlapping support frame is movably sleeved on the bottom surface of the support frame, and two sets of cylinders are movably overlapping on the top outer surface of the overlapping support frame.
[0009] Preferably, hydraulic rods are symmetrically fixedly installed on the inner walls of both sides of the overlapping support frame, and a movable bracket is fixedly connected to the output end of the hydraulic rod. An arc-shaped overlapping plate is fixedly installed on the outer surface of the movable bracket, and the outer surface of the arc-shaped overlapping plate is movably overlapped on the outer surface of the cylinder.
[0010] Preferably, a roller is provided on the inner wall of the arc-shaped overlapping plate, a motor is fixedly installed on one side surface of the arc-shaped overlapping plate, and a transmission roller that is movably sleeved on the outer surface of the arc-shaped overlapping plate is fixedly installed on the output end of the motor.
[0011] Preferably, the top surface of the overlapping support frame is provided with snap-fit grooves at both sides, and the outer surface of the snap-fit grooves is movably overlapped at the bottom sides of the support frame.

[0015] The beneficial effects of this utility model are:
[0016] This utility model provides a novel welding torch fixing support device. The swing-locking sleeve allows the output end of the arc welder on the inner wall to overlap the gap between two iron plates. The self-weight of one end of the arc welder ensures that the output end of the arc welder can always overlap the gap between the two iron plates. At this time, the arc welder is started to weld the gap between the iron plates. Then, the motor is pressed to rotate the threaded rod, and the threaded slider on the outer surface of the threaded rod drives the arc-shaped slider to move at a constant speed on the top surface of the support frame for welding. The self-weight of the arc welder ensures that the output end always overlaps the surface of the gap, so that the height, speed, welding efficiency and welding depth of the arc welder will not change too much when the iron plates are welded, and the gap can be precisely welded.
[0017] This utility model provides a novel welding torch fixing support device. The support frame is adjusted so that the contact point between the two iron plates is in the middle position of the support frame. The arc welder is snapped onto the inner wall of the snap-fit sleeve and snapped onto the outer surface of the mating limiting groove by a limiting strip. The limiting strip compresses the surface of the arc welder, increasing the friction between the arc welder and the snap-fit sleeve, thereby limiting the position of the arc welder and making it firmly positioned on the inner wall of the snap-fit sleeve.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0027] Specific implementation examples are given below.
[0028] Please see Figure 1 - Figure 6 This utility model provides a novel welding torch fixing support device, including a support frame 13 and two sets of iron plates 14 movably overlapping the outer surface of the bottom of the support frame 13. An arc-shaped limiting groove 131 is formed on the top surface of the support frame 13 and on the inner walls of both sides. A second motor 132 is fixedly installed on one side surface of the support frame 13. A threaded rod 133 movably overlaps the top surface of the support frame 13 and is fixedly connected to the output end of the second motor 132. A threaded slider 134 is threadedly and movably sleeved on the outer surface of the threaded rod 133. An arc-shaped slider 135 is fixedly connected to the outer surface of the threaded slider 134. The inner wall surface is movably connected to the outer surface of the support frame 13 and the arc-shaped limiting groove 131. A snap-fit sleeve 137 is provided on the outer surface of the arc-shaped slider 135. An arc welder 139 is movably fitted on the inner wall surface of the snap-fit sleeve 137. A limiting strip 138 is provided on the inner wall surface of the snap-fit sleeve 137. A butt-fit limiting groove 1310 is opened on the outer surface of the arc welder 139. The output end of the butt-fit limiting groove 1310 is movably connected to the gap between the two sets of iron plates 14. A rotating shaft 136 is movably fitted on the outer surface of the arc-shaped slider 135. The outer surface of the rotating shaft 136 is provided on the outer surface of the snap-fit sleeve 137.
[0029] During operation, the swing-locking housing 137 allows the output end of the arc welder 139 on the inner wall to overlap the gap between the two iron plates 14. Utilizing the self-weight of one end of the arc welder 139, the output end of the arc welder 139 can always overlap the gap between the two iron plates 14. At this time, the arc welder 139 is started to weld the gap between the iron plates 14. Then, the motor 132 is pressed to rotate the threaded rod 133, causing the threaded slider 134 on the outer surface of the threaded rod 133 to drive the arc-shaped slider 135 to move at a uniform speed on the top surface of the support frame 13 for welding. Utilizing the self-weight of the arc welder 139, the output end can always overlap the surface of the gap, so that when the iron plates 14 are being welded, the height, speed, welding efficiency, and welding depth of the arc welder 139 will not change too much, achieving a precise welding effect on the gap.
[0030] The support frame 13 is adjusted so that the contact point between the two iron plates 14 is in the middle position of the support frame 13. The arc welder 139 is snapped onto the inner wall of the snap-fit sleeve 137 and snapped onto the outer surface of the butt-fitting limiting groove 1310 by the limiting strip 138. The limiting strip 138 is used to squeeze the surface of the arc welder 139, increasing the friction between the arc welder 139 and the snap-fit sleeve 137, thereby limiting the position of the arc welder 139, so that the arc welder 139 can be firmly positioned on the inner wall of the snap-fit sleeve 137.
[0031] Furthermore, such as Figure 1 - Figure 2 and Figures 4 to 6 As shown, a limiting sleeve 1311 is fixedly installed on both sides of the support frame 13. A suction cup a2 is provided on the bottom surface of the limiting sleeve 1311. A cavity is opened on the inner wall of the limiting sleeve 1311 and the suction cup a2. A pull-out plate a1 is movably sleeved on the inner wall of the cavity. A soft strip a3 is provided on the bottom surface of the suction cup a2.
[0032] When welding iron plates 14 is required during operation, the support frame 13 is placed on the top surface of the two iron plates 14, and the pull plate a1 is pulled upward. At this time, the air inside the suction cup a2 will be drawn out as the pull plate a1 moves. The air density inside the suction cup a2 will decrease, and the pressure inside the suction cup a2 will decrease. Then, the soft strip a3 deforms after the pressure decreases, so that the suction cup a2 can be firmly attached to the top surface of the iron plate 14.
[0033] Furthermore, such as Figures 1 to 3As shown, an overlapping support frame 11 is movably sleeved on the bottom surface of the support frame 13. Two sets of cylinders 12 are movably overlapped on the top outer surface of the overlapping support frame 11. Hydraulic rods 112 are symmetrically fixedly installed on the inner walls of both sides of the overlapping support frame 11. A movable bracket 113 is fixedly connected to the output end of the hydraulic rods 112. An arc-shaped overlapping plate 114 is fixedly installed on the outer surface of the movable bracket 113. The outer surface of the arc-shaped overlapping plate 114 movably overlaps the outer surface of the cylinders 12. Rollers are provided on the inner wall of the arc-shaped overlapping plate 114. A motor 115 is fixedly installed on one side surface of the arc-shaped overlapping plate 114. A transmission roller 116 is fixedly installed on the output end of the motor 115 and movably sleeved on the outer surface of the arc-shaped overlapping plate 114. A snap-fit groove 111 is provided on the top surface of the overlapping support frame 11 and at the two side edges. The outer surface of the snap-fit groove 111 movably overlaps the two bottom edges of the support frame 13.
[0034] During operation, when the arc welder 139 needs to weld the cylinder 12, the two cylinders 12 are overlapped on the top surface of the overlap support frame 11. The moving bracket 113 is moved in conjunction with the hydraulic rod 112, so that the outer surface of the arc-shaped overlap plate 114 is attached to the bottom outer surface of the cylinder 12. The output end can be continuously overlapped at the gap between the two cylinders 12 by the self-weight of the arc welder 139. At this time, the transmission roller 116 on the outer surface of the moving bracket 113 rotates, so that the cylinder 12 will rotate on the inner wall of the two sets of arc-shaped overlap plates 114. During the rotation of the cylinder 12, the joint of the two sets of cylinders 12 is welded.
[0035] Working principle: When welding is required on the iron plate 14, the support frame 13 is attached to the top surface of the two iron plates 14, and the pull plate a1 is pulled upward. At this time, the air inside the suction cup a2 will be extracted as the pull plate a1 moves. At this time, the air density inside the suction cup a2 will decrease, and the pressure inside the suction cup a2 will decrease. Then, the soft strip a3 deforms after the pressure decreases, so that the suction cup a2 can be firmly attached to the top surface of the iron plate 14.
[0036] The support frame 13 is adjusted so that the contact point between the two iron plates 14 is in the middle position of the support frame 13. The arc welder 139 is snapped onto the inner wall of the snap-fit sleeve 137 and snapped onto the outer surface of the butt-fitting limiting groove 1310 by the limiting strip 138. The limiting strip 138 is used to squeeze the surface of the arc welder 139, increasing the friction between the arc welder 139 and the snap-fit sleeve 137, thereby limiting the position of the arc welder 139, so that the arc welder 139 can be firmly positioned on the inner wall of the snap-fit sleeve 137.
[0037] At this time, the swinging locking sleeve 137 allows the output end of the arc welder 139 on the inner wall to overlap the gap between the two iron plates 14. Utilizing the self-weight of one end of the arc welder 139, the output end of the arc welder 139 can always overlap the gap between the two iron plates 14. At this time, the arc welder 139 is started to weld the gap between the iron plates 14. Then, the motor 132 is pressed to rotate the threaded rod 133, causing the threaded slider 134 on the outer surface of the threaded rod 133 to drive the arc-shaped slider 135 to move at a uniform speed on the top surface of the support frame 13 for welding. Utilizing the self-weight of the arc welder 139, the output end can always overlap the surface of the gap, so that when the iron plates 14 are being welded, the height, speed, welding efficiency, and welding depth of the arc welder 139 will not change too much. This allows for precise welding of the gap, enabling a single set of arc welders 139 to perform all-round welding of different steel materials.
[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
