Abstract
The utility model discloses a hydraulic automatic dynamic meter, which is characterized in that the hydraulic automatic dynamic meter is formed by that a pulling ring, a rear lid, an oil reservoir, a seal ring, an oil seal draw rod, a measuring force meter, etc. Are orderly connected, wherein, the oil reservoir is of a full seal cylindrical middle hollow vessel which is filled with a certain amount of hydraulic oil. The measured force compresses static hydraulic oil through the oil seal draw rod which is positioned in the oil reservoir, and the size of the measured force is directly displayed on the head of the hydraulic automatic dynamic meter. The hydraulic automatic dynamic meter has the advantages of simple product structure, easy use, low cost, long service life and good versatility, which can be used as a single device or the coordinative composition of a device. The utility model belongs to a measuring force or weighing device which is used for measuring various stretching forces or gravities.
Description
The utility model relates to a kind of device for measuring force, particularly is applicable to the device for measuring force of measuring various stretching forces and gravity.
At present, measure the device of stretching force or gravity both at home and abroad, the elastic deformation of employing principle is generally arranged, three kinds of forms of Fundamentals of Sensors and hydraulic jack method, the device of these several forms all has weak point.Adopt the device for measuring force of elastic deformation principle to be suitable for surveying less and power stably, not high to large-tonnage and impulsive force dynamometry precision, and, the camber of spring ability is changed with the increasing of cycle index, cause the dynamometry precision to reduce; The dynamometer that adopts Fundamentals of Sensors is the change in resistance generation potential difference (PD) by strain resistor, again by devices such as amplifiers, directly show its stressed size, this kind device is reliable, but structure more complicated, cost is higher, and electron device is subject to surrounding environment influence and cause the dynamometry precision to change; With hydraulic jack method dynamometry, numerical value is reliable, but device volume is big, heavy, also will join oil pump in addition, uses very inconvenient.
The purpose of this utility model is to provide a kind of simple in structure, easy to use, the life-span is long, cost is low, the dynamometry scope is wide, precision is high hydraulic pressure automatic force instrument.
Hydraulic pressure automatic force instrument of the present utility model, be to adopt hydraulic transfering principle, in hermetic oil accumulator, inject a certain amount of hydraulic oil, make by dynamometry by being positioned at the oil sealing pull bar of oil accumulator, hydraulic oil to static state compresses, and hydraulic oil bears certain pressure and is delivered to gauge outfit, and is bigger by dynamometry, the pressure that hydraulic oil bears is bigger, and the gauge outfit indication is bigger.If adopt the oil accumulator of different size, then can be made into the dynamometer that to survey different tonnages.
Below, in conjunction with the accompanying drawings, the structure of the hydraulic pressure automatic force instrument of the utility model is described further.
Accompanying drawing is the structural representation of hydraulic pressure automatic force instrument.
(1)-draw ring (2)-bonnet
(3)-oil accumulator (4), (12)-O-ring seal
(5)-oil sealing pull bar (6)-Connection Block
(7), (8)-copper backing (9)-attaching nut
(10)-dynamometer gauge outfit (11)-gauge outfit joint
(13)-hydraulic oil
As shown in the figure, the hydraulic pressure automatic force instrument of the utility model is made up of the draw ring (1), bonnet (2), oil accumulator (3), O-ring seal (4), (12), oil sealing pull bar (5) and the dynamometer gauge outfit (10) that link to each other in turn.The hollow cylinder that oil accumulator (3) is that stomidium footpath is less, other end aperture is big, has internal thread, and cooperates formation one hermetically sealed container with oil sealing pull bar (5), being full of a certain amount of hydraulic oil in the container, its outer garden and aperture can be decided with the dynamometry scope.Oil sealing pull bar (5) closely cooperates with the oil accumulator inwall for being similar to the piston rod of T font, and two O-ring seals (4), (12) are respectively arranged on mating surface, and its path one end stretches out outside the oil accumulator (3), links to each other with tensioning equipment or measured object by external thread.Oil accumulator (3) top is welded with the Connection Block (6) of band internal thread, oil circuit, and dynamometer gauge outfit (10) links to each other with Connection Block (6) with dynamometer gauge outfit joint (11) by attaching nut (9), and communicates with oil accumulator (3).Oil accumulator bonnet (2) is to be with externally threaded nut, goes up on oil accumulator (3), and draw ring (1) one end links to each other with bonnet (2) by external thread, and the other end is the ring of garden shape, for be connected usefulness with measured object.
As a kind of conversion of the present utility model, oil sealing pull bar (5) miner diameter end can change into internal thread or latch socket and linking to each other with measured object or tensioning equipment.
As another conversion of the present utility model, be that adjustable automatic control contact can be housed on dynamometer gauge outfit (10), when the dynamometer meter pointer is gone to setting pulling force position, dynamometer can send signal automatically, by control circuit stretching process or weighing action are stopped automatically, with control stretch-draw and weighing process.
The oil accumulator of the hydraulic pressure automatic force instrument of the utility model and oil sealing pull bar adopt the medium carbon steel manufacturing, and O-ring seal can be made with rubber or polyamine fat.
When using the hydraulic pressure automatic force instrument measurement stretching force of the utility model, only need oil sealing pull bar (5) one ends are linked to each other with tensioning equipment or a certain point of fixity, draw ring (1) links to each other with measured object and gets final product; When measuring gravity (weigh), oil sealing pull bar (5) one ends and weighing equipment are joined, weight or hopper hang on the draw ring; For making things convenient for reading, also can adopt the connection opposite with above-mentioned method of attachment, be about to draw ring and link to each other with tensioning equipment or weighing equipment, oil sealing pull bar one end connects measured object or hopper.
The hydraulic automatic dynamic meter of the utility model has the certainty of measurement height, the advantages such as test specification is wide, and product structure is simple, easy to use, cost is low, the life-span is long, versatility well not only can be used separately or supporting with tensioning equipment, as the device for measuring force of measuring reinforcing bar or wire tensioning force, also can be supporting with automatic Metage Eguipment, make the automatic weighing measurer.
