Abstract
A servo-swaying actuator comprises a cylinder jacket and a piston matching with the cylinder liner, and is characterized in that the gap between the cylinder liner and the piston is provided with a nonmetal support and gland strip. The utility model is mainly used in a tester.
Description
Technical field
The utility model relates to the dynamic torsion testing machine of electro-hydraulic servo, relates in particular to the servo oscillating actuator on the dynamic torsion testing machine of electro-hydraulic servo.
Background technique
The servo oscillating actuator is the executive component of the dynamic torsion testing machine of electro-hydraulic servo.The shortcoming that common servo oscillating actuator exists is, the gap is very little between the oil cylinder piston, and the maximal clearance seals by one deck oil film between piston and the oil cylinder about 0.005-0.01mm.This structure manufacture difficulty is quite big, requires the geometric accuracy and the form and position tolerance of processing very high, and yield rate is very low.And adopt metallic sheath guiding and support, piston and cylinder body sintering phenomenon can occur after the long-time continuously test, thereby influence the life-span of actuator greatly.In the actual tests process, because fully impossible and servo oscillating actuator dead in line by the axis of test specimen, may produce side loading thus, carry out to cause in the alternation cyclic loading process oil film breakage between servo oscillating actuator piston and the cylinder body in the servo oscillating actuator, thereby make piston and cylinder sleeve sintering, cause the servo oscillating actuator to lose efficacy.
Summary of the invention
The utility model for overcome between the oil cylinder piston very little owing to the gap and the long-time continuously test of adopting metallic support to bring after sintering phenomenon may appear, thereby influence the problem in the life-span of actuator greatly.Developed servo oscillating actuator of new generation, it has low resistance, high response, long-life, the characteristics in big gap.
This programme is realized by following technical measures: it comprise cylinder sleeve and with the piston that cylinder sleeve matches, it is characterized in that being provided with in the gap between piston and the cylinder sleeve nonmetal support and Stamping Steel Ribbon.
The beneficial effect of this programme can be learnt according to the narration to such scheme, servo oscillating actuator of the present utility model is with the different of original technology maximum: the mode that adopts nonmetal support and Stamping Steel Ribbon sealing between cylinder sleeve and the piston, rather than employing clearance seal, avoid directly contacting between cylinder sleeve and the piston, thereby make the servo oscillating actuator can long-term operation.Because to the support of the servo oscillating actuator piston rod design that breaks traditions, adopt nonmetal support and Stamping Steel Ribbon sealing between piston and the cylinder body, lateral load from test specimen can directly not affact on piston and the cylinder sleeve, but affact on the nonmetal support ring, sintering phenomenon may appear after the long-time continuously test that can effectively avoid very little owing to the gap and adopt metallic supports to bring, gap increase simultaneously can make lubricant oil arrive nonmetal wear ring lubricate, thereby it is simple to have fabrication and processing, be easy to assembling, the characteristics of sintering and selflubricating not at a high speed, thereby the life-span of improving the servo oscillating actuator greatly.Therefore the utility model has compared with prior art been realized technical purpose.
The concrete characteristics of this programme also have, and making the gap between described piston and the cylinder sleeve is 0.4-0.5mm, greatly reduces difficulty of processing.The cylinder sleeve of described servo oscillating actuator is connected with bearing by 4 flat spring sheets; The cylinder sleeve of described servo oscillating actuator also can be connected with bearing by the spring sheet by 4 groups of stacked settings, avoids in process of the test from the axial deformation of the sample damage to the servo oscillating actuator.Described elastic steel sheet is 0.5 millimeter a spring steel plate.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 the utility model plan view;
Fig. 2 left view of the present utility model;
A-A sectional view among Fig. 3 Fig. 2;
Among the figure: 1, elastic steel sheet, 2, the servo oscillating actuator, 3, worktable, 4, nonmetal support, 5, Stamping Steel Ribbon, 6, cylinder sleeve, 7, piston.
Embodiment
Shown in Fig. 1～3, it comprises cylinder sleeve 6 and slides the pistons 7 of joining with cylinder sleeve 6 that piston rotates the alternation swing that realizes the servo oscillating actuator in cylinder sleeve.Nonmetal wear ring 4 and Stamping Steel Ribbon 5 are installed in the gap between piston 7 and the cylinder sleeve 6.Owing between piston and the cylinder sleeve nonmetal support ring has been installed, thereby make matching gap between the two can increase to 0.4-0.5mm, avoided directly contacting between piston and the cylinder sleeve, thus reach the servo oscillating actuator high speed alternation running piston with just overlap between sintering., avoid in process of the test to being vertically installed with the elastic support that the elastic steel sheet by stacked setting that worktable 3 and servo oscillating actuator are linked together is formed in the two end axles of the cylinder sleeve of servo oscillating actuator from the axial deformation of sample damage to the servo oscillating actuator.Described elastic steel sheet is 0.5 millimeter a spring steel plate.
