[0015] The specific embodiments of the present invention will be further described below in conjunction with the drawings and embodiments. The following embodiments are only used to explain the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0016] Such as figure 1 , figure 2 As shown, a valve pressure testing machine includes a frame 1, a workpiece base fixedly arranged on the frame 1, a sliding clamp base 3 slidably arranged above the workpiece base 2 in a vertical direction and matched with it , The first drive mechanism that drives the sliding clamp base 3 to slide, rotates the rotating sleeve 4 arranged on the frame 1, and only slides on the rotating sleeve 4 along the axis of the rotating sleeve 4 The inner top block 5, the positioning hole 6 opened on the top block 5, the reset cylinder 7 that drives the top block 5 to reset, the second driving mechanism that drives the rotation sleeve 4 to rotate, the rotation sleeve 4 The axis of rotation is perpendicular to the sliding direction of the sliding clamp base 3;

[0017] The workpiece base 2 is provided with a gas nozzle 8 and a connector 9 communicating with the gas nozzle 8. The connector 9 communicates with a gas pipe 10, and the gas pipe 10 is provided with a solenoid valve 11;

[0018] The second driving mechanism includes a swing rod 12 fixedly connected to the rotating sleeve 4 at one end, a second driving cylinder 14 for driving the swing rod 12 to rotate, and a piston rod of the second driving cylinder 14 is connected to the The middle part of the pendulum rod 12 is rotatably connected, and the other end of the pendulum rod 12 is a free end;

[0019] The frame 1 is also provided with a first limit sensor 15 and a second limit sensor 16 for detecting the position of the top block 5.

[0020] The first limit sensor 15, the second limit sensor 16 are connected to the controllers of the first drive cylinder 13, the second drive cylinder 14, the reset cylinder 7, and the solenoid valve 11 on the air pipe 10, and pass the first limit The sensor 15 and the second limit sensor 16 detect the position of the top block 5 so as to open or close accordingly.

[0021] Working process: Place the detected valve on the workpiece base 2 so that the gas nozzle 8 is aligned with the valve. The valve stem is inserted into the positioning hole 6 of the top block 5. When the valve stem is inserted, the top block 5 is pushed to move, and the limit sensor senses After that, the first drive mechanism drives the sliding clamp seat 3 to position the valve, the second drive mechanism drives the rotating sleeve 4 to rotate, and then drives the valve stem to turn to open the valve and start to inject gas. After completion, the second drive mechanism drives the valve stem to reset , The valve is closed, and the reset cylinder 7 pushes the top block 5 out, and the limit sensor senses to reset the first driving mechanism and the solenoid valve 11 on the gas pipe 10, and the valve can be removed with a high degree of automation.

[0022] The preferred implementation in this embodiment is that the first drive mechanism is a first drive cylinder 13, the cylinder of the first drive cylinder 13 is fixed on the frame 1, and the first drive cylinder 13 The piston rod is fixedly connected with the sliding clamp base 3.

[0023] The preferred implementation in this embodiment is that a push slider is slidably provided in the rotating sleeve 4, a spring is provided between the top block 5 and the push slider, and the piston rod of the reset cylinder 7 is connected to The top block 5 is fixedly connected, and the cylinder body of the reset cylinder 7 is fixed on the frame 1 through a first tie rod.

[0024] The preferred implementation in this embodiment is that the frame 1 is also provided with a limit cylinder, the cylinder of the limit cylinder is fixed to the frame 1 through a second tie rod, and the swing rod 12 is free The end conflicts with the piston rod of the limiting cylinder.

[0025] The basic principles, main features and advantages of the present invention are shown and described above. Those skilled in the industry should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements. These changes and improvements fall within the scope of the claimed invention. The scope of the claimed invention is determined by the appended claims. And its equivalent definition.
