A welding rod clamping device for welding

Abstract

This utility model belongs to the field of welding rod clamping technology, specifically a welding rod clamping device for welding. It includes a support frame and a hollow shell movably fitted onto the outer surface of the support frame, swing arms movably fitted onto the two side surfaces of the support frame, and a welding rod movably overlapping the outer surfaces of the hollow shell and the swing arms. A support fixing arm is fixedly connected to the top surface of the hollow shell, and round rollers are provided on the two end surfaces of the support fixing arm. When the hollow shell moves, it drives the round rollers on the two end surfaces of the support fixing arm to slide on the outer surface of the swing arm, thereby closing and compressing the extended end of the swing arm. This causes the R-shaped rounded corner at one end of the swing arm to fit against the outer surface of the welding rod. Simultaneously, the anti-slip pad on the inner wall of the R-shaped rounded corner undergoes soft deformation under the compression of the R-shaped rounded corner, effectively limiting welding rods of different thicknesses and lengths.

Description

Technical Field

[0001] This utility model belongs to the field of welding rod clamping technology, specifically a welding rod clamping device for welding. Background Technology

[0002] Welding rods are required during the welding process of workpieces, and welding rod clamps are needed in actual use. Welding rod clamps are devices used to fix welding rods.

[0003] A patent with publication number CN216177403U discloses a welding rod clamping device, including a mounting plate, a hydraulic cylinder, a piston rod, a connecting block, two connecting rods, two first connecting plates, and two second connecting plates. The hydraulic cylinder is fixedly connected to one side of the mounting plate. One end of the piston rod is connected to the hydraulic cylinder, and the other end of the piston rod passes through the mounting plate and extends to the other side of the mounting plate. The connecting block is fixedly connected to the end of the piston rod away from the hydraulic cylinder. One end of each of the two connecting rods is hinged to both ends of the connecting block. One end of each of the two first connecting plates is fixedly connected to the side of the mounting plate away from the hydraulic cylinder. One end of each of the two second connecting plates is hinged to the other end of the two first connecting plates, and clamping components are fixedly connected to the other ends of each of the two second connecting plates. This welding rod clamping device can quickly and easily clamp and fix the welding rod, is simple to operate, convenient to use, and can effectively protect the welding rod.

[0004] In current technology, traditional welding rods need to be fixed with welding clamps, which require employees to hold them by hand. However, hand-holding cannot maintain the same force at all times. If the force is too loose, the welding rod will wobble or fall off. If the clamping force is too great, the end of the welding rod may deform and get stuck on the surface of the welding clamp. This also means that tools are needed to disassemble the welding rod later.

[0005] Therefore, a welding rod clamping device for welding 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 welding rod clamping device for welding is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The welding rod clamping device of this utility model includes a support frame and a hollow shell movably sleeved on the outer surface of the support frame, a swing arm movably sleeved on both sides of the support frame, and a welding rod movably overlapped on the outer surfaces of the hollow shell and the swing arm. A support fixing arm is fixedly connected to the top surface of the hollow shell, and round rollers are provided on both ends of the support fixing arm. A semi-circular arc plate is fixedly connected to one side surface of the hollow shell. An elastic wire is fixedly connected to the outer surface of the tail end of the swing arm. An R-shaped rounded corner is provided at one end of the swing arm. An anti-slip pad is fixedly connected to the inner wall of the R-shaped rounded corner. The outer surfaces of the R-shaped rounded corner and the semi-circular arc plate are movably sleeved on the outer surface of the welding rod.

[0008] Preferably, a slot is opened on the outer surface of the hollow shell, and a limit rod is fixedly connected to the inner wall of the slot.

[0009] Preferably, the outer surface of the hollow shell is movably fitted onto the inner wall of the slot, and the outer surface of the roller is movably overlapped onto the outer surface of the swing arm.

[0010] Preferably, a limiting groove is provided on the outer surface of one end of the support frame, the outer surface of the limiting groove is movably sleeved on the inner wall of the swing arm, and the position of the limiting groove is set at the middle position of the swing arm.

[0011] Preferably, an elastic wire is fixedly connected to one side surface of the support frame at the middle position of the limiting circular groove, and the other end of the elastic wire is fixedly connected to the inner wall of the empty groove.

[0012] Preferably, a limiting groove is formed on the inner wall of the support frame at the two sides of the elastic wire, and the outer surface of the limiting rod is movably sleeved on the inner wall of the limiting groove.

[0013] Preferably, a rope coiling machine is fixedly installed on the bottom surface of the support frame, and a tension rope is fixedly connected to the output end of the rope coiling machine.

[0014] Preferably, the outer surface of the tension rope is movably sleeved on the outer surface of the support frame, and the tail end of the tension rope is fixedly connected to the outer surface of the hollow shell.

[0015] The beneficial effects of this utility model are:

[0016] This utility model provides a welding rod clamping device for welding. It works with a rope coiling machine to retract the tension rope and move the hollow shell on the outer surface of the support frame toward the tail end of the support frame. This causes the outer surface of the semi-circular plate to detach from the surface of the welding rod. When the roller on the top surface of the hollow shell passes the position of the limiting groove, the front half of the swing arm is unobstructed. Under the pull of the elastic wire, the swing arm swings around the limiting groove as the axis. At this time, the front half of the swing arm will unfold to both sides and detach the inner wall of the anti-slip pad from the surface of the welding rod. This achieves the effect of fixing the surface of the welding rod in multiple ways using the semi-circular plate and the anti-slip pad. During disassembly, it can also be peeled off layer by layer, making disassembly more convenient and quick. The welding rod can always maintain the same clamping force.

[0017] This utility model provides a welding rod clamping device. When the hollow sleeve moves, it drives the round rollers on both ends of the support and fixing arm to slide on the outer surface of the swing arm, thereby closing and compressing the unfolded end of the swing arm. This causes the R-shaped rounded corner on one end of the swing arm to fit against the outer surface of the welding rod. The R-shaped rounded corner and the semi-circular plate limit the position of the welding rod. At the same time, the anti-slip pad on the inner wall of the R-shaped rounded corner undergoes soft changes under the pressure of the R-shaped rounded corner, effectively compressing welding rods of different thicknesses and lengths and limiting the position of the welding rod.

Detailed Implementation

[0025] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figure 1 - Figure 5 This utility model provides a welding rod clamping device, including a support frame 11 and a hollow shell 12 movably sleeved on the outer surface of the support frame 11, a swing arm 13 movably sleeved on both sides of the support frame 11, and a welding rod 14 movably overlapped on the outer surfaces of the hollow shell 12 and the swing arm 13. A support fixing arm 123 is fixedly connected to the top surface of the hollow shell 12, and a round roller 124 is provided on both ends of the support fixing arm 123. A semi-circular arc plate 125 is fixedly connected to one side surface of the hollow shell 12. An elastic wire 133 is fixedly connected to the outer surface of the tail end of the swing arm 13. An R-shaped rounded corner 131 is provided at one end of the swing arm 13. An anti-slip pad 132 is fixedly connected to the inner wall of the R-shaped rounded corner 131. The outer surfaces of the R-shaped rounded corner 131 and the semi-circular arc plate 125 are movably sleeved on the outer surface of the welding rod 14.

[0028] During operation, after the welding rod 14 is welded, the tension rope 115 is retracted in conjunction with the rope coiling machine 114, and the hollow sleeve 12 on the outer surface of the support frame 11 moves towards the tail end of the support frame 11, causing the outer surface of the semi-circular plate 125 to detach from the surface of the welding rod 14. When the roller 124 on the top surface of the hollow sleeve 12 passes the position of the limiting groove 111, the front half of the swing arm 13 is unobstructed and, under the pull of the elastic wire 133, the swing arm 13 swings around the limiting groove 111 as the axis. At this time, the front half of the swing arm 13 will unfold to both sides and the anti-slip pad 132 will be extended. The inner wall surface is detached from the surface of the welding rod 14, achieving multi-faceted fixation of the surface of the welding rod 14 using the semi-circular arc plate 125 and anti-slip pad 132. It can also be peeled off layer by layer during disassembly, making disassembly more convenient and quick. The welding rod can maintain the same clamping force, avoiding the need for welding pliers to fix the traditional welding rod. The welding pliers require employees to hold them by hand, and hand fixation cannot maintain the same force. Loose force will cause the welding rod to shake or fall. Excessive clamping force can easily cause the tail end of the welding rod to deform and get stuck on the surface of the welding pliers. Tools are still needed to disassemble the welding rod later.

[0029] Furthermore, such as Figures 1 to 5 As shown, a slot 121 is opened on the outer surface of the hollow sleeve 12. A limiting rod 122 is fixedly connected to the inner wall of the slot 121. The outer surface of the hollow sleeve 12 is movably sleeved on the inner wall of the slot 121. The outer surface of the roller 124 is movably overlapped on the outer surface of the swing arm 13. A limiting groove 111 is provided on the outer surface of one end of the support frame 11. The outer surface of the limiting groove 111 is movably sleeved on the inner wall of the swing arm 13. The limiting groove 111 is positioned at the middle of the swing arm 13. One side surface of the support frame 11 is fixed at the middle position of the limiting groove 111. An elastic wire 113 is connected to the inner wall of the hollow groove 121. A limiting groove 112 is opened on the inner wall of the support frame 11 at the two sides of the elastic wire 113. The outer surface of the limiting rod 122 is movably sleeved on the inner wall of the limiting groove 112. A rope coiling machine 114 is fixedly installed on the bottom surface of the support frame 11. A tension rope 115 is fixedly connected to the output end of the rope coiling machine 114. The outer surface of the tension rope 115 is movably sleeved on the outer surface of the support frame 11. The tail end of the tension rope 115 is fixedly connected to the outer surface of the hollow shell 12.

[0030] During operation, when replacing the welding rod 14, the tail end of the welding rod 14 is overlapped on the inner wall of the semi-circular plate 125, and the tension rope 115 is loosened by the rope coiling machine 114. At this time, the elastic wire 113 on one side surface of the support frame 11 pushes the hollow shell 12, causing the semi-circular plate 125 on one end of the hollow shell 12 to push the welding rod 14 in the same direction. As the hollow shell 12 moves, it drives the rollers 124 on both ends of the support fixing arm 123 to move on the outer surface of the swing arm 13. The surface is slid, and then the unfolded end of the swing arm 13 is closed and compressed, so that the R-shaped fillet 131 on one end of the swing arm 13 is attached to the outer surface of the welding rod 14. The position of the welding rod 14 is defined by the R-shaped fillet 131 and the semi-circular plate 125. At the same time, the anti-slip pad 132 on the inner wall of the R-shaped fillet 131 is softly changed under the compression of the R-shaped fillet 131, so as to effectively compress welding rods 14 of different thicknesses and lengths and define the position of the welding rod 14.

[0031] Working principle: After the welding rod 14 is welded, the tension rope 115 is retracted in conjunction with the rope coiling machine 114, and the hollow shell 12 on the outer surface of the support frame 11 moves to the tail end of the support frame 11, so that the outer surface of the semi-circular plate 125 is detached from the surface of the welding rod 14. When the roller 124 on the top surface of the hollow shell 12 passes the position of the limiting groove 111, the front half of the swing arm 13 is unobstructed, and under the pull of the elastic wire 133, the swing arm 13 swings around the limiting groove 111 as the axis. At this time, the front half of the swing arm 13 will unfold to both sides and detach the inner wall of the anti-slip pad 132 from the surface of the welding rod 14. This achieves the effect of fixing the surface of the welding rod 14 in multiple ways using the semi-circular plate 125 and the anti-slip pad 132. During disassembly, it can also be peeled off layer by layer, making disassembly more convenient and quick. The welding rod can always maintain the same clamping force.

[0032] As the hollow housing 12 moves, it causes the rollers 124 on both ends of the supporting fixed arm 123 to slide on the outer surface of the swing arm 13, thereby closing and compressing the extended end of the swing arm 13. This causes the R-shaped fillet 131 on one end of the swing arm 13 to align and adhere to the outer surface of the welding rod 14. The R-shaped fillet 131 and the semi-circular plate 125 are used to limit the position of the welding rod 14. At the same time, the anti-slip pad 132 on the inner wall of the R-shaped fillet 131 undergoes soft changes under the pressure of the R-shaped fillet 131, effectively compressing welding rods 14 of different thicknesses and lengths and limiting the position of the welding rods 14.

[0033] 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.
