The invention discloses a control system for a machine tool rolling functional component precision retaining ability measurement device. An industrial control computer is arranged on a force application component servo motor (701), and an eight-axis PMAC card is installed inside the industrial control computer. The control system is used for accomplishing machining path input, setting of tool parameters and cutting parameters, total cutting force calculation, total cutting force time curve drawing, total torque calculation and total torque time curve drawing; cutting component force in the X-axis direction, cutting component force in the Y-axis direction and cutting component force in the Z-axis direction are calculated, a time curve of the cutting component force is drawn, the cutting component force in the X-axis direction, the cutting component force in the Y-axis direction, the cutting component force in the Z-axis direction and the total toque are combined to be decomposed to all servo shafts, the component force time curve of each servo shaft is calculated, and the time curve is divided by the spring coefficient K on a force application mechanism to obtain the time displacement curve of each servo shaft. During operation of a control program, the displacement value of each servo shaft is output to a control PMAC axis control card through a lock widget, the PMAC card calls a corresponding motion control program, the servo motor is controlled to move to the corresponding displacement point, and needed force is applied.

The invention relates to an air pressure stabilization system and method for controlling pore water pressure in coal and rock mass creep tests, belonging to the technical field of coal seam tests. Composed of pneumatic valve, exhaust port and reactor; the system uses the idea of ​​feedback adjustment to transmit the air pressure signal in the reactor through the sensor, and at the same time, the signal processor converts the air pressure signal into a control command to control the switch of the automatic adjustment solenoid valve , and at the same time automatically adjust the solenoid valve to control the switch of the pneumatic valve, and then control the pressure in the reactor; the system is reliable in operation, simple in structure and easy to operate, and can provide a stable environment for creep experiments of coal and rock mass under the action of water as the medium pressure.

The invention provides a brake caliper self-adjusting screw sleeve high pressure air tight detection clamp, which comprises a clamp base plate. The clamp base plate is provided with a bearing support and a lower sealing seat. The bearing support is provided with a vertical guide post and a horizontal guide post. The upper end of the vertical guide post and the back end of the horizontal guide post are equipped with a vertical cylinder mounting plate and a horizontal cylinder mounting plate to have a cylinder installed. The vertical guide post is also equipped with a moveable sliding plate with an upper sealing head. The horizontal guide post is also provided with a horizontally locking slide plate, a horizontally locking baffle plate, a spring positioning sleeve return spring and a limit lever. The horizontally locking slide plate and the horizontally locking baffle plate are provided with a clamp locking sleeve. The lower sealing seat is provided with a test component fixing sleeve. In the invention, a float locking mechanism is adopted to not only avoid the mechanism requiring the hydraulic pressure in the up-pressure process but also to make convenient clamping and save space. The combination of the test component fixing sleeve and material unloading cylinder realizes the function of easy clamping of the test component and convenient unloading of materials. In the testing process, high pressure gas replaces hydraulic pressure, which not only improves the experimental environment but also eliminates the cleaning of the test component after the test.
