Abstract

The invention discloses an adjustable travel detection device. The device comprises a base, a stand column, a lead screw, a hand wheel, a feeding nut, a sliding seat, locking mechanisms, a support, aguide screw rod, a first adjusting nut, a to-be-tested oil cylinder, a connecting assembly, a pressure detection mechanism, a limiting mechanism, a calibration sleeve, a counterweight seat, locking mechanisms, an ejection and lifting screw rod, a second adjusting nut, a marking block and a ruler, wherein the to-be-tested oil cylinder moves downwards, due to the fact that a pulling pressure sensoris in a floating state, the pulling pressure sensor can accurately detect pressure when the pressure detection mechanism is in contact with the ejection and lifting screw rod; and when a pressure value reaches a set value, the locking mechanisms are driven to be acted, so that an electromagnet is electrified, the calibration sleeve is locked by a profiling chuck, and then the travel under calibration thrust can be obtained. The device is simple in structure and can carry out band-load stroke detection on oil cylinders with different travel, not only high in inspection precision, but also rapidin and convenient to adjust, so that the error part in the idle-load travel can be effectively eliminated, installation of the to-be-tested oil cylinder is convenient and rapid, and the precision ishigh.

Description

technical field [0001] The invention relates to a detection device, in particular to an adjustable stroke detection device. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. The stroke of the hydraulic cylinder is generally determined at the time of design, but due to manufacturing and assembly errors, the actual stroke does not conform to the theoretical stroke, and the current detection method is mostly to measure the stroke without load. Deformation will also cause the actual stroke to be inconsistent with the theoretical stroke, resulting in the user being unable to grasp the...
