The riveting fixture body 100 is also provided with:

[0024] A convenient clamping mechanism is provided, and the convenient clamping mechanism includes a clamping component disposed inside the end frame 107. A screw-in adjustment component is provided at the connection between one side of the clamping component and the inner side of the end frame 107, and a guide component is provided on the side of the clamping component.

[0025] In order to facilitate the vertical clamping, installation, and riveting of the steel pipe body 102 by means of a clamping assembly, in this embodiment, preferably, the clamping assembly includes a second V-shaped clamping block 1072 fixed to one side of the inside of the end frame 107 by mounting bolts, and a first V-shaped clamping block 1071 provided on the other side of the inside of the end frame 107. The first V-shaped clamping block 1071 has the same structure as the second V-shaped clamping block 1072. When the steel pipe body 102 is closed, it can contact the inner surface of the second V-shaped clamping block 1072. The first V-shaped clamping block 1071 can be moved again to clamp the surface of the steel pipe body 102 for reinforcement and installation. It also facilitates the vertical clamping, installation, and precise riveting of the steel pipe body 102 by means of the first V-shaped clamping block 1071 and the second V-shaped clamping block 1072 during installation.

[0026] In order to facilitate the screwing adjustment and reinforcement installation of the V-shaped clamp 1071 by means of the screwing adjustment assembly, in this embodiment, preferably, the screwing adjustment assembly includes an adjusting threaded rod 1073 threadedly connected through an internal threaded hole. The end of the adjusting threaded rod 1073 is connected to the side of the V-shaped clamp 1071 by a bearing, which facilitates the squeezing, moving and clamping of the V-shaped clamp 1071 when the adjusting threaded rod 1073 is screwed in by hand, and facilitates vertical installation during fixed installation.

[0027] In order to facilitate the stable screwing and adjustment of the V-shaped clamp 1071 by means of the guide assembly, in this embodiment, preferably, the guide assembly includes guide rods 1074 fixedly installed on both sides of the V-shaped clamp 1071, and two guide sliding holes 1075 are opened on the inner side of the end frame 107, and the guide rods 1074 are slidably connected to the inside of the guide sliding holes 1075, so that the V-shaped clamp 1071 can drive the guide rods 1074 to slide inside the guide sliding holes 1075 during the screwing and adjustment, so as to stabilize the adjustment and use.

[0028] The reinforcement and stabilization mechanism includes two sets of fixed connection components located at the middle position of the lower surface of the main tooling frame 101. The inner surface of the fixed connection components is provided with reinforcement clamping components, which can reinforce and stabilize the end surfaces of the main tooling frame 101 and the valve 103 during the welding and fixing operation, thereby making the riveting and welding tooling body 100 more stable for riveting and welding operation.

[0029] To facilitate the installation and adjustment of the reinforcing clamp 1014 using a fixed connection assembly, in this embodiment, preferably, the fixed connection assembly includes two fixing plates 1011 welded and fixed to the middle position of the lower surface of the main tooling frame 101. The top of the inner end of the fixing plate 1011 is provided with a control groove 1012, and a control slider 1013 is provided inside the control groove 1012. The control slider 1013 can be slidably connected inside the control groove 1012 to slide and adjust the reinforcing clamp 1014, which facilitates the limited installation of the reinforcing clamp 1014 and the convenient adjustment operation.

[0030] To facilitate the reinforcement and welding of the tooling main frame 101 and valve 103 after surface reinforcement and installation, in this embodiment, preferably, the reinforcement and clamping assembly includes a reinforcement clamping plate 1014 welded and fixed to the end of the control slider 1013. A reinforcement threaded rod 1015 is threadedly connected to one bottom side of the fixing plate 1011 through an internal threaded hole. A handwheel 1016 is fixed to one end of the reinforcement threaded rod 1015, which is convenient for hand-held handwheel 1016 to drive the reinforcement threaded rod 1015 to rotate and adjust. The other end of the reinforcement threaded rod 1015 is connected to the side of the reinforcement clamping plate 1014 through a bearing. The inner surface of the reinforcement clamping plate 1014 matches the top surface structure of the valve 103 until the reinforcement threaded rod 1015 is rotated in to drive the reinforcement clamping plate 1014 to clamp and fix the end surface of the valve 103 for reinforcement and installation.

[0031] The working principle and usage process of this utility model are as follows: Before use, the steel pipe riveting and welding fixture is first fixedly installed. The main frame 101 of the fixture can be closed and placed on the top of the valve 103. After the main body 100 of the riveting and welding fixture is placed, the handwheel 1016 is used to drive the reinforcing threaded rod 1015 to be screwed in and adjusted at the bottom of the fixed plate 1011 through the threaded structure. When the reinforcing threaded rod 1015 is screwed in and adjusted, it squeezes and moves the reinforcing clamping plate 1014. When the reinforcing clamping plate 1014 moves, the top of the control slider 10 is moved. 13. The sliding control inside the control groove 1012 is used until the bottom end of the reinforcing clamp 1014 is squeezed and fixed on the top surface of the valve 103, so that the riveting and welding fixture body 100 is placed on the surface of the valve 103 for reinforcement during use. This makes the riveting and welding fixture body 100 more fixed and stable for welding operations on the steel pipe body 102 after installation, and less prone to errors. This improves the convenience of the riveting and welding fixture body 100 in reinforcing the valve 103 during the riveting and welding operation of the steel pipe body 102 and the stability of the welding use.

[0032] Then, after the main tooling frame 101 and valve 103 are fixedly placed, the end frame 107 is slidably adjusted to the riveting position by sliding the guide slider 106 and the guide rail 105, and then reinforced by the locking bolts. After fixing, the steel pipe body 102 extends from the inside of the end frame 107 to the end surface of the valve 103. When closing the installation, the inner surface of the V-shaped clamp 1072 contacts one side surface of the steel pipe body 102. Then, the adjusting thread rod 1073 is screwed in through the internal thread structure of the internal thread hole. When the adjusting thread rod 1073 is screwed in, it drives the V-shaped clamp 107. 1. The movement of V-shaped clamping block 1071 drives the guide rod 1074 to slide inside the guide sliding hole 1075 until the V-shaped clamping block 1071 is stably moved and clamped on the other side of the surface of the steel pipe body 102, which facilitates the clamping and fixing of the steel pipe body 102. In addition, the V-shaped clamping block 1071 and V-shaped clamping block 2 1072 make it easy to ensure that the steel pipe body 102 is vertically clamped and installed during clamping and installation, quickly aligning the riveting and welding without the need for manual operation. The welding is accurate and low-cost, improving the convenience of fixing and installing the main body 100 of the riveting and welding fixture on the steel pipe body 102 and the riveting and welding effect.
