Abstract
A pneumatic fixture comprises cylinders, which is characterized in that the cylinders consist of two symmetrical cylinders, cylinder connecting rods of the two cylinders are respectively connected with a chuck, and the chucks hinged with the cylinder connecting rods are driven by the cylinder connecting rods. The pneumatic fixture is reasonable in structural design, can be adaptable to automatic control of clamping fixation of test pieces in a locomotive brake test stand and increases working efficiency and safety.
Description
Technical field
The utility model belongs to the field of components that grips of pneumatic actuation, is specifically related to a kind of air-actuated jaw that is used for locomotive, car brakeing machine testing table.
Background technology
Air-actuated jaw generally adopts cylinder or electronic control, and to realize the clamping control function under its automatic control, existing anchor clamps are widely used in also being used for material test such as silk thread, aluminium foil in the macromolecular materials tests such as plastics, rubber, film.On for example small-sized tension tester, electronic tensile machine, the system controlled by computer electronics universal testing machine, it has advantages such as esy to use, safe and reliable, that clamping force is stable.
It is the important way of the locomotive air brake being carried out safety and postitallation evaluation that the test of locomotive air brake detects, and detects the running status of simulating brake machine on locomotive by test, can comprehensively understand every performance of brake and newly-increased valve member thereof.Existing brake experiment table all adopts artificial fixing and dismounting testpieces, and for example testpieces such as single valve, steam supply valve, vent valve, relay valve is fixing.It is fixing that existing air-actuated jaw can't be applicable to that this testpieces combines with clamping between testing table.And manual type can exist bigger potential safety hazard and operation careless omission, also can cause the situation generation that influences the experimental result authenticity because of the difference that connects parameter sometimes.
The utility model content
Of the present utility modelly provide a kind of reasonable in design, can be applicable to the automatic control that grips of testpieces in the locomotive brake gear testing table, realized the air-actuated jaw of good experiment effect.
The technical solution adopted in the utility model is as follows:
A kind of air-actuated jaw comprises cylinder, it is characterized in that described cylinder is symmetrically arranged two, and the air cylinder connecting rod of two cylinders is connected with chuck respectively, and the hinged setting of described chuck and air cylinder connecting rod is also driven by air cylinder connecting rod.
Described cylinder upper end fixedly installs the cylinder Connection Block respectively, and described cylinder Connection Block is the spacing setting of air cylinder connecting rod, the terminal hinged setting of the upper end of air cylinder connecting rod and chuck.
Described two cylinder Connection Blocks fixedly install a support respectively, and described two cylinders are fixed together by support.
Described two chucks are oppositely arranged the formation hold assembly, the hinged connecting link that is provided with on the described support, and the other end of connecting link and chuck leading section are hinged.
Hinged two connecting links that are provided with on the described support, the upper end of two connecting links respectively with the hinged setting in full end of two chucks.
This air-actuated jaw adopts cylinder as actuator, by inflation and the venting to cylinder, can realize the action that grips and the decontrol control to chuck.By two be set up in parallel below cylinder form actuator, the air cylinder connecting rod of two cylinders carries out hinged respectively at the end of two chucks, when the piston of cylinder moves, the drive air cylinder connecting rod moves up and down, air cylinder connecting rod drives chuck again and realizes moving up and down of chuck end, thereby the connecting link of chuck leading section can be realized the clamping and the loosening up of the swing realization chuck of chuck.Two chucks like this can cooperate realize testpieces and testing table corresponding port well with firmly dock, promptly can guarantee the butt joint parameter consistency of a plurality of testpieces, can save manually-operated loaded down with trivial details degree again, improve the science of experimental result, realize robotization control.
The beneficial effects of the utility model are, the reasonable in design of this air-actuated jaw can be applicable to the automatic control that grips of testpieces in the locomotive brake gear testing table, increases work efficiency and security.
Description of drawings
Fig. 1 is the cut-away section structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1, this air-actuated jaw is by two cylinders 10,20, cylinder Connection Block 12,23, fixing bracket body 50, connecting link 13,24,14,15,16,25,26,27 and two chucks that are oppositely arranged of hinged pin 30,40 are formed, and the cylinder piston rod 11,22 of two cylinders is hinged with chuck respectively, chuck and rod hinge connection setting.Cylinder is fixedly installed on the below of cylinder Connection Block, the terminal hinged setting of the upper end of air cylinder connecting rod and chuck.Moving anchor clamps comprise fixing bracket body, and support body is fixedlyed connected with the cylinder Connection Block, the leading section of Connection Block and rod hinge connection.Thereby the piston 21 of cylinder 20 is moved and drives cylinder piston rod 22 rectilinear motions, drives chuck, connecting link 13,24, the curvilinear motion of realization chuck 30,40 by hinged 14,15,16,25,26,27, thus the keying that realizes chuck is controlled.
Claims (5)
