The invention discloses a hydraulic pressure generator for an automatic pressure calibration stand. A servo motor (2) is fixed in a calibration stand shell by a motor bracket (3). The spindle of the motor (2) is connected with a screw mandrel (10) by a belt wheel (5) and a conveyer belt (6). The screw mandrel (10) is arranged in a screw mandrel bracket (8) by a bearing (4) and a gland (7). The both ends of the screw mandrel (10) are respectively connected with the belt wheel (5) and an I-shaped slider (11) connected with one end of a piston rod (12). The piston rod (12) is connected with the piston of an oil pressure cylinder (15) by a piston bracket (14). The oil pressure cylinder (15) is provided with a pressure output interface (16). On the basis of improving the pressure generating efficiency and shortening the pressure generating time, the invention can generate pressure stably, avoiding the impact and the damage on the calibration control instrument when the pressure changes suddenly and protecting the instrument effectively. With automatic and stable detection, the invention can also improve the detection accuracy and reduce the noise.
Description
technical field [0001] The invention relates to a hydraulic pressure generating device of an automatic pressure calibration table, which is especially suitable for being matched with a pressure measuring instrument such as a pressure calibration controller in a high-pressure state to realize automatic measurement and control of pressure. Background technique [0002] Under high pressure conditions, the pressure source required for precise pressure measurement and control is mainly hydraulic pressure generation, so as to ensure that the set pressure value is reached in a short period of time. At present, the manual hydraulic pressure generation method is widely used. The manual hydraulic pressure generation method: first, the pressure is artificially controlled, which is easy to cause pressure overshoot, which will cause impact damage to the calibration control instrument, which is required to avoid by the national metrology verification regulations; second, the work intensity...
