Description
Technical Field
[0001] This utility model relates to the field of seamless steel pipe technology, specifically to a fixture for testing seamless steel pipes. Background Technology
[0002] Seamless steel pipes are made by piercing a whole round steel bar. They are steel pipes without weld seams on the surface. Before use, seamless steel pipes need to be tested using testing equipment. Clamps are needed to fix the seamless steel pipes for testing.
[0003] Existing testing fixtures are mostly fixed, and cannot be adjusted according to the length of seamless steel pipes when clamping them. This leads to loosening of the clamping during testing, reducing clamping stability. Existing testing methods mostly use single-point, single-sided testing, which cannot test other sides of the seamless steel pipe, resulting in inaccurate test data and reduced testing accuracy. To address this, we propose a new fixture for testing seamless steel pipes. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This seamless steel pipe inspection fixture uses a controller to start a rotating motor, which drives a bidirectional threaded rod to rotate and generate force with the threaded groove. This causes the slider to move within the movable groove, allowing the slider to move the moving plate horizontally. The fixture can be adjusted according to the length of the seamless steel pipe. The seamless steel pipe is placed on the fixed limit block, and the electric rod is started to move the movable limit block to clamp the seamless steel pipe. This prevents the steel pipe from shifting during inspection and improves clamping stability.
[0013] 2. This seamless steel pipe testing fixture places the seamless steel pipe on a fixed limiting block. Activating the electric lever moves the movable limiting block to clamp the seamless steel pipe. The controller starts the motor, which drives the gears to rotate, creating a force between the gears and the gear block, thus rotating the turntable and adjusting the angle of the seamless steel pipe. Activating the cylinder moves the pneumatic lifting rod, which in turn moves the pressure test block to press different surfaces of the seamless steel pipe for testing, improving testing accuracy.

[0023] Please refer to it again. Figure 1-2A bracket 110 is fixedly connected to the top of the base 100. The bracket 110 is used to install a rotary motor 111. The rotary motor 111 is fixedly connected to the upper right side wall of the bracket 110. The rotary motor 111 is used to drive a bidirectional threaded rod 112 to rotate. The end of the power output shaft of the rotary motor 111 is fixedly connected to the bidirectional threaded rod 112. The bidirectional threaded rod 112 passes through the bracket 110. A cylinder 120 is fixedly connected to the top of the bracket 110. The cylinder 120 is used to drive a pneumatic lifting rod 121 to move. The power output shaft of the cylinder 120 passes through the bracket 110. The end of the power output shaft of the cylinder 120 is fixedly connected to the pneumatic lifting rod 121. A movable groove 130 is opened on the top of the base 100. The movable groove 130 is used to install a slider 131. Slider 131 is movably connected to both the left and right sides of the inner cavity of the movable groove 130. The slider 131 is fixedly connected to the moving plate 200. The slider 131 is used to drive the moving plate 200 to move.
[0024] Please refer to it again. Figure 1-4 The movable plate 200 is located on the upper left and right sides of the base 100. Specifically, the movable plate 200 is movably connected to the base 100 via a slider 131. A turntable 210 is rotatably connected to the inner cavity of the movable plate 200. The turntable 210 is used to drive the fixed limiting block 211 to rotate. The fixed limiting block 211 is fixedly connected to the bottom of the inner cavity of the turntable 210. An mounting plate 212 is fixedly connected between the upper sides of the front and rear side walls of the inner cavity of the turntable 210. An electric rod 213 is fixedly connected to the top of the mounting plate 212. The electric rod 213 is used to drive the movable limiting block 214 to move. The power output shaft of the electric rod 213 passes through the mounting plate 212. The movable limiting block 214 is fixedly connected to the end of the power output shaft of the electric rod 213. A groove 220 is opened on the outer wall of the turntable 210. The inner cavity of the groove 220... A toothed block 221 is fixedly connected to the bottom and arranged sequentially from top to bottom. The toothed block 221 is used to generate force with the gear 232. The bottom of the inner cavity of the movable plate 200 has an installation groove 230. The lower side of the left and right side walls of the movable plate 200 are respectively fixedly connected to a motor 231. The power output shaft of the motor 231 passes through the movable plate 200 and extends into the inner cavity of the installation groove 230. The end of the power output shaft of the motor 231 is fixedly connected to a gear 232. The gear 232 is rotatably connected to the toothed block 221. The gear 232 is used to generate force with the toothed block 221. The upper rear side of the left side wall of the movable plate 200 has a threaded through groove 240. A bidirectional threaded rod 112 passes through the threaded through groove 240. The threaded through groove 240 is used to generate force with the bidirectional threaded rod 112, thereby driving the movable plate 200 to move.
[0025] In summary, by starting the rotating motor 111 through the controller 150, the bidirectional threaded rod 112 is driven to rotate and generate force with the threaded groove 240, thereby driving the slider 131 to move within the movable groove 130. The slider 131 then drives the movable plate 200 to move horizontally, which can be adjusted according to the length of the seamless steel pipe. The seamless steel pipe is placed on the fixed limit block 211, and the electric rod 213 is started to drive the movable limit block 214 to move and clamp the seamless steel pipe. This prevents the steel pipe from shifting during testing and improves the clamping stability.
[0026] Please refer to it again. Figure 2 A protective pad 113 is embedded in the upper right side wall of the bracket 110. The protective pad 113 is used to prevent friction from damaging the parts.
[0027] Please refer to it again. Figure 2 The threads in the threaded through groove 240 mesh with the threads of the bidirectional threaded rod 112, which causes the bidirectional threaded rod 112 to exert force on the threaded through groove 240, thereby driving the moving plate 200 to move.
[0028] Please refer to it again. Figure 1-2 The base 100 has four fixed support legs 140 at its bottom corners, which are used to support the base 100.
[0029] Please refer to it again. Figure 1-2 The end of the pneumatic lifting rod 121 is fixedly connected to a pressure test block 122. The pressure test block 122 is used to pressurize the seamless steel pipe and perform a pressure test on the seamless steel pipe.
[0030] Please refer to it again. Figure 1 The front side wall of the base 100 is embedded with a controller 150, and the controller 150 is electrically connected to the rotating motor 111, the cylinder 120 and the motor 231 via wires. The controller 150 is used to control the rotating motor 111, the cylinder 120 and the motor 231.
[0031] In summary, by placing the seamless steel pipe on the fixed limiting block 211, activating the electric rod 213 to move the movable limiting block 214 to clamp the seamless steel pipe, and activating the motor 231 via the controller 150 to rotate the gear 232, causing the gear 232 to interact with the toothed block 221, thereby rotating the turntable 210 and adjusting the angle of the seamless steel pipe, and activating the cylinder 120 to move the pneumatic lifting rod 121, which in turn moves the pressure test block 122 to press different surfaces of the seamless steel pipe for testing, thus improving the accuracy of the test.
[0032] In practical applications, when faced with seamless steel pipes of different lengths, the controller 150 starts the rotating motor 111, which drives the bidirectional threaded rod 112 to rotate and generate force against the threaded groove 240. This causes the slider 131 to move within the movable groove 130, allowing the slider 131 to move the moving plate 200 horizontally. This movement can be adjusted according to the length of the seamless steel pipe. The seamless steel pipe is then placed on the fixed limit block 211, and the electric rod 213 is activated to move the movable limit block 214 to clamp the seamless steel pipe, preventing it from shifting during testing. To prevent deviation, during the compression test of the seamless steel pipe, the seamless steel pipe is placed on the fixed limiting block 211. The electric rod 213 is activated to move the movable limiting block 214 to clamp the seamless steel pipe. The motor 231 is activated by the controller 150, which drives the gear 232 to rotate, so that the gear 232 and the tooth block 221 exert force, thereby driving the turntable 210 to rotate, and driving the seamless steel pipe to rotate and adjust the angle. The cylinder 120 is activated to drive the pneumatic lifting rod 121 to move, and drive the compression test block 122 to move and squeeze different surfaces of the seamless steel pipe for testing.
