[0002] Embedded parts are components pre-installed in concealed projects. They are components placed during the pouring of the structure and are used for overlapping when building the upper structure to facilitate the installation and fixation of the foundation of external engineering equipment. Embedded parts are mostly made of metal, welded by plates and steel bars, and the plates are usually cast iron.

[0003] Before welding, it is necessary to open a plug hole on the plate. During welding, the steel bar is usually inserted into the plug hole manually, and then the welding gun is held around the steel bar to fully weld the connection between the steel bar and the plate. The welding efficiency of manual handheld welding gun is low, and during welding, in order to facilitate the insertion of the steel bar into the plug hole, the hole diameter of the plug hole will be designed to be slightly larger than the diameter of the steel bar, resulting in a slight tilt when the steel bar is inserted into the plug hole. The verticality of the steel bar and the plate cannot be guaranteed during manual welding, which makes it easy for the steel bar to be welded crooked, affecting its use. Utility Model Content

[0017] See also Figures 1 to 3The embodiment of the present application provides an automatic welding device for embedded plate, including a conveyor 1 and a welding gun 2. The conveyor 1 is a mesh chain conveyor 1 or a chain plate conveyor 1 or a belt conveyor 1 in the prior art. The conveyor 1 includes a frame 11 and a conveyor belt 12. The welding gun 2 is located above the conveyor belt 12 and is used to weld the embedded plate 3 conveyed by the conveyor belt 12. The embedded plate 3 includes a plate 31 and a steel bar 32. A cross linear slide 4 is installed on the top of the frame 11. The output of the cross linear slide 4 A mounting seat 5 is installed at the end, and a hollow rotating table 6 and a parallel clamp 71 are installed on the lower end surface of the mounting seat 5. The hollow rotating table 6 is driven by a stepper motor, and the parallel clamp 71 is a pneumatic clamp or an electric clamp. The welding gun 2 is fixedly connected to the output end of the hollow rotating table 6; the clamping mechanism 7 includes a parallel clamp 71, an extension plate 72 and a clamping plate 73. The parallel clamp 71 is located at the inner center of the hollow rotating table 6, and the clamping end of the parallel clamp 71 is installed with an extension plate 72, and the lower end of the extension plate 72 is installed with a clamping plate 73.

[0018] In this embodiment, four evenly distributed steel bars 32 are inserted on the design plate 31. The plate 31 with the steel bars 32 is placed on the conveyor belt 12 with the steel bars 32 facing upward, and the embedded plate 3 is conveyed to the preset position by the conveyor belt 12; then the cross linear slide 4 drives the mounting seat 5 to move so that one of the steel bars 32 is located in the middle of the two clamps 73, and then the parallel clamps 71 drive the two clamps 73 to move together, thereby clamping the steel bar 32 and correcting the slightly tilted steel bar 32. At this time, the axis of the steel bar 32 is aligned with the hollow The rotation center lines of the rotating table 6 coincide with each other; then the hollow rotating table 6 works, and the hollow rotating table 6 drives the welding gun 2 to rotate one circle, and the welding gun 2 fully welds the connection between the steel bar 32 and the plate 31; after welding one steel bar 32, the parallel clamp 71 drives the two clamps 73 to move away, and the cross linear slide 4 drives the mounting seat 5 to move horizontally and vertically, so that the clamps 73 move to both sides of the next steel bar 32, and the steel bar 32 is located in the middle of the two clamps 73, and the welding of the next steel bar 32 begins, and the cycle is repeated until the welding of four steel bars 32 is completed. Finally, the conveyor belt 12 transports the plate 31 after welding, and then transports the next plate 31 to be welded.

[0019] The steel bar 32 is clamped by the clamping plate 73 and corrected to ensure the verticality of the steel bar 32 and the plate 31. The welding gun 2 is driven to rotate around the steel bar 32 by the hollow rotating table 6, which can improve the welding efficiency and the welding quality of the embedded plate 3.

[0020] In a preferred embodiment, in order to facilitate the conveyor 1 to transport the embedded plate 3 to the preset position, please refer to Figures 1 to 3In this embodiment, a positioning mechanism 8 is also provided, and the positioning mechanism 8 includes a first hinge seat 81, a first cylinder 82, a second hinge seat 83, a baffle 84, a fixed seat 85, a second cylinder 86, and a positioning plate 87. The first hinge seat 81, the second hinge seat 83 and the fixed seat 85 are all fixedly mounted on the frame 11. One end of the first cylinder 82 is hinged to the first hinge seat 81, and the other end is hinged to the baffle 84. The baffle 84 is hinged to the second hinge seat 83. Two symmetrically arranged fixed seats 85 are fixed on the frame 11, and the second cylinder 86 is installed on the fixed seats 85. The output end of the second cylinder 86 is installed with a positioning plate 87. The baffle 84 has a release state and a restricted state. When the baffle 84 is in the release state, the baffle 84 is located on one side of the conveyor belt 12; when the baffle 84 is in the restricted state, the baffle 84 is located above the conveyor belt 12, and the length direction of the baffle 84 is perpendicular to the conveying direction of the conveyor belt 12.

[0021] In order to detect whether the plate 31 is in contact with the baffle 84, a contact switch 88 is fixedly mounted on the baffle 84. After the plate 31 contacts the contact switch 88, it will contact the baffle 84. Through the feedback signal of the contact switch 88, it can be known that the plate 31 is in contact with the baffle 84.

[0022] For the convenience of baffle plate 84 rotating to the conveyor belt 12, a notch 111 for the movement of baffle plate 84 is provided on the frame 11. By providing the notch 111 on the frame 11, the frame 11 can be prevented from interfering with the rotation of baffle plate 84.

[0023] When the conveyor belt 12 conveys the plate 31 to the preset position, the first cylinder 82 drives the baffle 84 to rotate. When the baffle 84 is in the restricted state, the baffle 84 is located above the conveyor belt 12, and the length direction of the baffle 84 is perpendicular to the conveying direction of the conveyor belt 12; when the conveyor belt 12 conveys the plate 31 to the baffle 84, it contacts the contact switch 88, compresses the contact of the contact switch 88, and then contacts the baffle 84. Through the feedback signal of the contact switch 88, it can be known that the plate 31 is in contact with the baffle 84, and then the conveyor belt 12 stops conveying; the second cylinder 86 drives the positioning plate 87 to extend, and the two positioning plates 87 clamp the plate 31, and at the same time align the plate 31, so that the position of the plate 31 is in the preset position, and the insertion point of the steel bar 32 on the plate 31 is fixed, so the steel plate is also in the preset position, which is convenient for the clamping plate 73 to accurately clamp the steel bar 32; even if the steel bar 32 is slightly tilted, the steel bar 32 will be corrected in the process of the clamping plate 73 clamping the steel bar 32, so that the steel bar 32 remains vertical.

[0024] In a preferred embodiment, in order to facilitate the clamping plate 73 to clamp the steel bar 32, the steel bar 32 can be corrected so that the steel bar 32 can be vertical. Figure 2 and Figure 3The clamping plates 73 are arranged in a V-shaped structure. The V-shaped clamping plates 73 have a limiting function, and the steel bars 32 are limited in the V-shaped grooves of the two clamping plates 73, so that the angle can be corrected.
