Automatic pressure measuring machine of jack

Abstract

The invention relates to an automatic pressure measuring machine of a jack. The automatic pressure measuring machine consists of a work bench, a motor, a gear box, a crankshaft, a push and pull rod, a pressure adjusting rod, a control panel and a pressure probe. The control panel is installed above the work bench; the pressure probe is arranged under the control panel; a fixed plate is arranged below the work bench; and the motor is fixed at the fixed plate and is connected with the gear box. The output end of the gear box is connected with the crankshaft that is connected with the push and pull rod; the push and pull rod is connected with the pressure adjusting rod by a universal joint. The requirement that the crankshaft push and pull rod and the pressure adjusting rod need to be at the same plane can be reduced; and the jack is protected. The pressure probe and the control panel are connected by threads, so that testing of jacks with different heights and specifications can be realized and thus the machine has high practicability.

Description

technical field [0001] The invention relates to the field of pressure detection, in particular to a jack automatic pressure measuring machine. Background technique [0002] The degree of automation of the jack pressure measuring machine is poor, and the staff needs to continuously press the pressure regulating rod and lift the thrust rod to achieve the purpose of pressure measurement, but the continuous pressing of the pressure regulating rod up and down will cause certain fatigue to the testing personnel, resulting in low detection efficiency. In the utility model of application number 201320407319.7, the inventor drives the reciprocating motion of the push-pull rod through the motor-driven eccentric wheel, so that the pressure regulating rod can pressurize the jack, which reduces the labor intensity of the staff, but due to the reciprocating motion of the push-pull rod , The jack will have a certain position deviation, and the crankshaft, push-pull rod, and pressure regula...

[0002] The automation degree of the jack pressure measuring machine is poor, and the staff need to continuously press the pressure regulating rod and lift the thrust rod to achieve the purpose of pressure measurement, but the continuous pressing of the pressure regulating rod up and down will cause certain fatigue to the testing personnel, resulting in low detection efficiency

In the utility model of application number 201320407319.7, the inventor drives the reciprocating motion of the push-pull rod through the motor-driven eccentric wheel, so that the pressure regulating rod can pressurize the jack, which reduces the labor intensity of the staff, but due to the reciprocating motion of the push-pull rod , the jack will have a certain position deviation, and the crankshaft, push-pull rod, and pressure regulating rod will deviate from the same plane, which may cause damage to the jack during the test

Secondly, in this utility model, the pressure probe and the control panel are fixedly installed. Since the jacks have various specifications and different heights, the height requirements of the jacks to be tested are relatively high, which cannot meet the requirements of jacks that are too low or too high.
