Abstract
The utility model is an air brake valve performance test bench. The test bench comprises a fixed installation pedestal; an electric servo-cylinder is fixedly installed on the installation pedestal and has a push rod penetrating through the pedestal and a hole arranged in a workpiece installation disk; the workpiece installation disk is fixed through a connecting rod fixed on the installation pedestal; and the push rod is also provided with a force transducer thereon. The beneficial effects of the test bench are that: by arranging the electric servo-cylinder, the loading precision is high, the loading range is large, the loading requirements for various parts during a test are met, the generality of the test bench is raised, and the test precision, the flexibility and the degree of automation are improved obviously.
Description
Technical field
The utility model belongs to a kind of checkout equipment, is a kind of performance testing equipment that relates to gas brake valve class concretely.
Background technology
The existing field of valve class of using is very extensive, yet the performance detection apparatus of valve class is had their own characteristics each.At home, many colleges and universities, scientific research institution, vehicle equipment manufacturing enterprises have all developed the air brake valve detection testing table of oneself, and what have sells in market.These equipment promote that to improving the air brake valve product quality technical progress of industry has played positive impetus, but also Shortcomings part, be mainly manifested in: (1) is difficult to satisfy the testing requirement of new standard according to old standard design.New standard has all been made some and has been revised at aspects such as measuring accuracy, test condition, test requests, and has increased some new test events, and the test macro of the old standard development of foundation is difficult to satisfy the new standard requirement; (2) tested object and test function are failed all over products and the project of coverage criteria requirement.Because the diversity of tested object and test event need to be carried out holistic approach to each test products and test event, under the succinct prerequisite of assurance system, extract the gas circuit design that to satisfy all testing requirements; (3) loading characteristic of charger can not satisfy the multiple parts loading such as hand brake valve, foot brake valves, spring cylinder requirement fully, needs to adopt electrical servo to load to satisfy the demands comprehensively.(4) system complex is not easy to Installation and Debugging, and expensive.Existing testing table volume is larger on the market, and system architecture is complicated, and price is in hundreds thousand of units.Need system's gas circuit is carried out Optimal Structure Designing, the reusability of gas circuit when improving the various products of test and project reduces the system complex degree, with Cost reduction.
Therefore, be necessary existing checkout equipment is improved for above problem, a kind of equipment of suitable gas valve performance test is provided.
The utility model content
The purpose of this utility model just provides a kind of air brake valve performance test stand, and it is large that this testing table has a loading range, and the loading demand in the time of can satisfying multiple parts test improves the versatility of testing table.A kind of air brake valve performance test stand of the present utility model, it is characterized in that: described testing table comprises a fixing mounting base, be installed with electric servo cylinder on the described mounting base, described electric servo cylinder has a push rod to pass pedestal, and pass the hole that arranges in the workpiece mounting disc, described workpiece mounting disc fixes by the connecting link that is fixed on the mounting base, and strong sensor also is installed on push rod.By this device is set, can carry out the straight line imposed load by push rod to workpiece by electric servo cylinder, make a service test, and because strong sensor, can detect accurately the size of imposed load, so that loading accuracy is high, loading range is large, loading demand in the time of can satisfying multiple parts test, the versatility of raising testing table.
Further, also be furnished with rail plate between described workpiece mounting disc and pedestal, described push rod and power sensor are fixed on a connection piece, and web member is installed on the rail plate, can endwisely slip at rail plate.By rail plate, can play the guiding role and the steady load increment.
Further, described connecting link is by arranging moving axially of boss restriction workpiece mounting disc.By boss is set, make the workpiece mounting disc be fixed on certain position, be unlikely to generation and move axially.
Further, described rail plate be distributed in two ends, the push rod left and right sides and arrange each one.The present invention's point more is conducive to guide effect
Further, described connecting link passes workpiece mounting disc one end and is provided with screw thread.Point of the present invention is convenient to the installation of fixation workpiece with fixing.
Beneficial effect
The beneficial effects of the utility model are by the testing table of electric servo cylinder is set, so that loading accuracy is high, loading range is large, the loading demand in the time of can satisfying multiple parts test, improve the versatility of testing table, measuring accuracy, dirigibility, automaticity be improved significantly.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
Embodiment
A kind of air brake valve performance test stand of the present utility model as shown in the figure, described testing table comprises a fixing mounting base 2, be installed with electric servo cylinder 1 at mounting base 2, described electric servo cylinder 1 has a push rod 4 to pass mounting base, push rod 4 also passes the hole that arranges in the workpiece mounting disc 6, described workpiece mounting disc 6 fixes by the connecting link 5 that is fixed on the mounting base 2, and strong sensor 3 also is installed on push rod 4.
In the present embodiment, also be furnished with rail plate 7 between workpiece mounting disc 6 and mounting base 2, described push rod 4 is fixed on a connection piece 8 with power sensor 3, and web member is installed on the rail plate, can endwisely slip at rail plate 7.
In the present embodiment, connecting link 5 is by arranging moving axially of boss restriction workpiece mounting disc 6.
In the present embodiment, described rail plate 7 for be distributed in two ends, push rod 4 left and right sides and arrange each one.
In the present embodiment, connecting link 5 passes workpiece mounting disc 6 one ends and is provided with screw thread.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
