Description
Technical field
The present invention relates to a kind of linear rolling guide test platform, particularly a kind of linear rolling guide heavy duty life test machine.
Background technology
Linear rolling guide is as a kind of novel rolling function parts, and it has been widely used in aspects such as numerically-controlled machine, exact instrument.For the most important performance of linear rolling guide is its load capacity, and life-span and the reliability under load environment, moved.
With reference to Fig. 4, at present, general linear rolling guide load test equipment; Guideway 11 to be tested is installed on the lathe base 12; Slide block on the test guideway 11 is through portal frame 13 vertical loading, and portal frame is installed two cover auxiliary guide rails pairs 14 for 13 times, carries out reciprocal running-in.Take this sample loading mode, auxiliary guide rail secondary 14 will bear half the loading force, often will change auxiliary guide rail pair 14, the trouble that changes the outfit, consumes resources after the test once or twice; In addition, this structure is tested guideway running-in simultaneously if realize many covers, and the portal frame span will increase, and pedestal more will be done wide, and it is huge that one-piece construction seems, is unfavorable for realizing.
Summary of the invention
In order to overcome the deficiency of prior art; The present invention provides a kind of guideway of simulating receiving serviceable life and reliability actual under the different loads, and is rational in infrastructure, practical; Easy to operate, once can carry out the straight-line rolling guide set heavy duty life test machine that many cover guideways are tested simultaneously.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of linear rolling guide heavy duty life test machine; Comprise pedestal; On the said pedestal motor is installed, motor is connected with slide unit through screw mandrel, and the left and right sides of said slide unit bottom is equipped with the auxiliary guide rail pair and is connected with pedestal top; Said slide unit top is provided with left and right hydraulic cylinder, and the push rod on the left and right hydraulic cylinder is connected with the test guideway that is arranged on pedestal left and right sides sidepiece through pressing plate; Adopt the life test machine of this structure; Guideway to be tested adopts two sides symmetry mounting means, once carries out two groups of guideway life-span running-in tests simultaneously, in addition; The force transfering device that parts such as hydraulic cylinder and pressing plate are formed is the left-right symmetric structure and arranges; The power of two hydraulic cylinders output is cancelled each other in pedestal, and test load is not born or born less to the auxiliary guide rail pair, prolongs the serviceable life of auxiliary guide rail.
Improvement as linear rolling guide heavy duty life test machine of the present invention; Said push rod and pressing plate top are hinged; Flexibly connect through connecting rod between the middle part of pressing plate and the slide unit, the bottom cross-under of said pressing plate has interior last item, and interior last item is hinged with the briquetting that is installed on the test guideway; Adopt the force transfering device of this structure, guarantee that effectively pressing plate and test guideway are on the same plane of constraint.
As the further improvement of linear rolling guide of the present invention heavy duty life test machine, said in last item pass the bottom of pressing plate and through hold-down nut pressure transducer be fixed on the outside of pressing plate.The use of pressure transducer can detect the load data of actual loaded on the test guideway.
Further, said pressure transducer is regulated the load of left and right hydraulic cylinder input through hydraulic servo control system.Hydraulic servo control system can be realized feedback regulation through detecting the load data that loads on the guideway, guarantees the stability of loaded load.
Further, said pedestal left and right sides sidepiece is symmetrically arranged with the datum clamp face of many group different in width test guideways and screws is installed.Thereby the test guideway that adapts to different in width is installed.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
With reference to Fig. 1～Fig. 3; A kind of linear rolling guide heavy duty life test machine; Comprise pedestal 1; On the said pedestal 1 motor 2 is installed, motor 2 is connected with slide unit 4 through screw mandrel 3, and the left and right sides of said slide unit 4 bottoms is equipped with auxiliary guide rail pair 5,5 ' and is connected with pedestal 1 top; Said slide unit 4 tops are provided with left and right hydraulic cylinder 6,6 ', and push rod on the left and right hydraulic cylinder 6,6 ' 61,61 ' is connected with the test guideway 8,8 ' that is arranged on pedestal 1 left and right sides sidepiece through pressing plate 7,7 '.
The pressing plate 7 of this testing machine, 7 ' is with test guideway 8, can directly be connected between 8 ' as required; Also can connect indirectly through force transfering device; Its syndeton is: said push rod 61,61 ' and pressing plate 7,7 ' top be hinged; Flexibly connect through connecting rod 9,9 ' between pressing plate 7,7 ' middle part and the slide unit 4, said pressing plate 7,7 ' bottom cross-under have interior last item 71,71 ', interior last item 71,71 ' and be installed in the briquetting of testing on the guideway 8,8 ' 72,72 ' and be hinged.This design adopts connecting rod as fulcrum, and when top rod driving pressing plate upper end moves forward, exert pressure to the test guideway through interior last item and briquetting in the lower end of pressing plate; And when move backward top rod driving pressing plate upper end; The lower end of pressing plate applies pulling force through interior last item and briquetting to the test guideway; This structure is not only simple in structure; And guarantee that effectively pressing plate and test guideway are on the same plane of constraint, thereby guarantee that load vertically is applied on the test guideway.
Said pressure transducer 10,10 ' is regulated control through hydraulic servo control system to the load of left and right hydraulic cylinder 6,6 ' input.Hydraulic servo control system can be realized feedback regulation through detecting the load data that loads on the guideway, guarantees the stability of loaded load.Certainly according to actual needs, pressure transducer can also be installed in other positions, as long as guarantee to detect the load data that loads on the guideway.
Said pedestal 1 left and right sides sidepiece is symmetrically arranged with many group different in width test guideway 8,8 ' datum clamp face and screw is installed, thereby the test guideway that adapts to different in width is installed.
This testing machine once carries out two groups of guideway life-span running-in tests, in addition simultaneously because guideway to be tested adopts two sides symmetry mounting means; The force transfering device that parts such as hydraulic cylinder and pressing plate are formed is the left-right symmetric structure and arranges; The power of two hydraulic cylinders output is cancelled each other in pedestal, and test load is not born or born less to the auxiliary guide rail pair, prolongs the serviceable life of auxiliary guide rail; And; Because test force is born by pedestal, the one-piece construction of dwindling proving installation is simplified in the output that therefore can improve test force.Thereby can be widely used in simulating linear rolling guide and receive its actual serviceable life and reliability of test under the different loads.
