[0016] As Figures 1-6 shown: a flange joint welding tool, including workbench 1, workbench 1 is a three-dimensional frame, the upper portion of workbench 1 is flat plate 11; the top of flat plate 11 is fixedly connected with a plurality of fixed bases 2, the plurality of fixed bases 2 are equidistantly distributed left and right, and each fixed base 2 is provided with a fixed cylinder 3 on the front and back sides, the fixed cylinder 3 is fixedly connected to the top of flat plate 11, the fixed base 2 and the fixed cylinder 3 are matched with the structure of flange joint 4, the flange joint 4 is sleeved between the top of fixed base 2 and fixed cylinder 3, the rear side wall of workbench 1 is fixedly connected with support frame 5, the top of support frame 5 extends forward, the top of support frame 5 is fixedly installed with air cylinder 6 on the front side of the middle portion, the cylinder column of air cylinder 6 penetrates through the top of support frame 5 downward, the piston rod of air cylinder 6 is in sliding fit with support frame 5, air cylinder 6 is provided with sleeve 7 on the left and right sides, the sleeve 7 is fixedly connected to the top of support frame 5, the bottom of sleeve 7 penetrates through the top of support frame 5, the bottom end of piston rod of air cylinder 6 is fixedly connected with linkage plate 8 perpendicularly, the top of linkage plate 8 is fixedly connected with guide rod 9 perpendicularly on the left and right ends, the two guide rods 9 are respectively inside two sleeves 7, the two guide rods 9 are in sliding fit with two sleeves 7 respectively, the bottom of linkage plate 8 is fixedly connected with a plurality of pressure heads 10, the number of pressure heads 10 is same as that of fixed bases 2, and the plurality of pressure heads 10 are respectively located directly above the plurality of fixed bases 2.
[0017] Firstly, the flange joints 4 to be welded are placed between the top of fixed base 2 and fixed cylinder 3 one by one, the fixed bases 2 are equidistantly distributed left and right, so that each flange joint 4 can be stably placed in the specified position, and the design of fixed cylinder 3 further enhances the stability of flange joint 4, preventing displacement of flange joint 4 during welding.
[0018] After confirming that all the flange joints 4 have been placed correctly, the tool is ready to be started, at this time, the air cylinder 6 is in the initial state, its cylinder column is not extended, and the linkage plate 8 and the pressure head 10 thereon are also in the higher position.
[0019] The air cylinder 6 is started, and the cylinder column starts to move downward. Since the bottom end of the cylinder column is fixedly connected with the linkage plate 8, the linkage plate 8 also moves downward. At the same time, the left and right ends on the top of the linkage plate 8 slide with the sleeve 7 through the guide rod 9, ensuring that the linkage plate 8 remains stable and horizontal during the descending process.
[0020] With the continuous descent of the linkage plate 8, the pressure head 10 gradually approaches and finally presses the flange joint 4. Since the number of the pressure head 10 is the same as that of the fixed base 2, each flange joint 4 can be effectively pressed, ensuring that no movement occurs during the welding process.
[0021] After the pressure head 10 presses the flange joint 4 tightly, the welding operation can be started. After the welding is completed, the cylinder column rises, driving the linkage plate 8 and the pressure head 10 back to the initial position, so as to take out the welded flange joint 4. The utility model only protects the mechanical part, and the functions related thereto realized through the software control part are not within the protection range of the utility model.
