DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 to Figure 3 In the embodiment of the utility model, an anchor chain welding device includes a workbench 1, and two slide grooves 3 are provided at the top of the workbench 1. The inner wall of the slide groove 3 is slidably connected with a slider 4. The top of the slider 4 is fixedly connected with a placement block 2 located at the top of the workbench 1. The top of the placement block 2 is formed with a quarter groove that matches the arc of the anchor chain; a power mechanism for driving the placement block 2 to slide is installed at the bottom end of the workbench 1, and a protective mechanism that penetrates the top of the workbench 1 is installed at the bottom end of the workbench 1. A clamping mechanism is installed at the top of the workbench 1, and the clamping mechanism cooperates with the placement block 2 to clamp the anchor chain; the power mechanism includes a gear 21 rotatably installed at the bottom end of the workbench 1, and two racks 20 are meshed on the outer side of the gear 21. The ends of the two racks 20 that are away from each other are fixedly connected to the bottom end of the slider 4, and a hydraulic push rod 22 is installed at the bottom end of the workbench 1. The output end of the hydraulic push rod 22 is fixedly connected to the end of a rack 20.

[0019] In this embodiment: First, the anchor chain is placed on the placement block 2. Since the top of the placement block 2 is formed with a quarter groove that matches the arc of the anchor chain, the stability of the anchor chain placement can be maintained. Then, the clamping mechanism is started to clamp the anchor chain. After the device is powered on, the disconnected position of the anchor chain is semi-melted due to the high temperature. The power mechanism is started synchronously, and the power mechanism clamps the anchor chain to achieve a fusion connection at the melted position. When the clamping mechanism is clamping, the clamping mechanism drives the protection mechanism to protect the welding position, limit the slag generated by welding from escaping, and improve the safety of welding.

[0020] Please refer to Figure 1 and Figure 2 The clamping mechanism includes a forward and reverse motor 15 installed on the top of the workbench 1, and the output end of the forward and reverse motor 15 is connected to a worm 16, and the outer periphery of the worm 16 is meshed with a worm wheel 17, and the worm wheel 17 is interference fitted on the outer periphery of the synchronous shaft 18. The clamping mechanism also includes two fixed ears 5 fixed to the top of the workbench 1, and a rotating ear 6 is rotatably installed on the inner side of the fixed ear 5. The two rotating ears 6 are fixedly connected to the two ends of the synchronous shaft 18, and the synchronous shaft 18 is rotatably connected to the fixed ear 5. One end of the rotating ear 6 is fixedly connected to a swing arm 7, and one end of the swing arm 7 is fixedly connected to a conductive voltage block 8.

[0021] In this embodiment: by starting the forward and reverse motor 15, the forward and reverse motor 15 drives the worm 16 to rotate, at which time the spiral part of the outer periphery of the worm 16 drives the worm wheel 17 to rotate, and the rotating worm wheel 17 drives the two rotating ears 6 to rotate through the synchronous shaft 18, and the rotating ears 6 drive the swing arm 7 to rotate downward, and the swing arm 7 can drive the conductive voltage block 8 to rotate downward to press the upper part of the anchor chain. The forward and reverse rotation of the forward and reverse motor 15 can control the swing arm 7 and the conductive voltage block 8 to rotate upward or downward, so as to press the anchor chain or cancel the pressing of the anchor chain.

[0022] Please refer to Figure 1 The protective mechanism includes a lower protective cover 14 detachably connected to the top of the workbench 1 and an upper protective cover 13 located above the lower protective cover 14, one end of the upper protective cover 13 is fixedly connected to a fixing plate 11, a lifting rod 10 slidably connected to the workbench 1 is fixedly installed at the bottom end of the fixing plate 11, a protrusion is provided at one end of the bottom of the lifting rod 10 passing through the workbench 1, a spring 19 is fixedly connected between the protrusion and the workbench 1, and compression rods 12 protruding outward are fixedly connected on both sides of the fixing plate 11.

[0023] The upper protective cover 13 and the lower protective cover 14 are respectively hollow box-shaped structures with open lower and upper ends. Openings matching the shape of the anchor chain are respectively provided at the bottom end of the upper protective cover 13 and the top of the lower protective cover 14.

[0024] In this embodiment: during the downward rotation of the swing arm 7, the swing arm 7 and the pressure rod 12 gradually approach and contact each other. At this time, the pressure rod 12 is squeezed by the extrusion force and drives the fixed plate 11 to move downward. The downward moving fixed plate 11 drives the lifting rod 10 to move downward. At this time, the spring 19 is stretched, and the downward moving fixed plate 11 drives the upper protective cover 13 to move downward. When the swing arm 7 rotates to a horizontal state, the bottom opening of the upper protective cover 13 and the top opening of the lower protective cover 14 are closed to each other, so that the welding gap of the anchor chain can be covered.

[0025] Please refer to Figure 1 The interior of the swing arm 7 is a hollow structure, and a circular hole is opened on the outer periphery of the swing arm 7. The wire 9 passes through the circular hole and extends to the inner cavity of the swing arm 7 and is electrically connected to the conductive voltage block 8.

[0026] In this embodiment, after the anchor chain is compressed, the two conductive blocks 8 are electrically connected to the positive and negative electrodes of the power supply through the wires 9. At this time, as the power mechanism is compressed, when the two ends of the notch of the anchor chain are butted, the current passes through the anchor chain to form a loop. Due to the conductivity and resistance of the metal, the current is hindered and heat is generated, so that the temperature of the workpiece increases and reaches a melting or plastic state, thereby realizing the welding operation.

[0027] Please refer to Figure 1 The cavity inside the upper protective cover 13 and the lower protective cover 14 is larger than the welding position size of the anchor chain.

[0028] In this embodiment: during the welding process, the welding slag generated by high temperature can be blocked by the upper protective cover 13 and the lower protective cover 14 when splashing, and contained in the protective cover. After the welding is completed, the lower protective cover 14 connected by threads can be removed and the residue therein can be dumped out.

[0029] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
