Description
Technical field
The utility model belongs to Mechanics Performance Testing equipment, is specifically related to a kind of clamping centralising device of electric dielectric test machine.
Background technology
Under hydrogen gas environment, material mechanical performance testing apparatus mainly adopts the form of docking high pressure hydrogen environment case on existing electric dielectric test machine host, sample is arranged on inside hyperbaric environment case, is then loaded the Mechanics Performance Testing carried out under hydrogen medium by testing machine main frame.For reducing hydrogen use amount, the design space of high pressure hydrogen environment case is less, is difficult to adopt hydraulically operated fixture clamping sample.If directly adopt the plain clamp that screw thread or boss connect, easily produce and misalign phenomenon, additional bending moment suffered by sample is large, has a strong impact on the validity of test findings.
Misalign and be mainly divided three classes: 1. Parallel misalignment, namely the center line of upper and lower fixture is parallel to each other but does not overlap, and there is radial displacement; 2. drift angle misaligns, i.e. there is drift angle between the center line of upper and lower fixture; 3. mixing misaligns, and namely there is Parallel misalignment and drift angle misaligns simultaneously.
Utility model content
The technical problems to be solved in the utility model is, overcomes the deficiencies in the prior art, proposes a kind of clamping centralising device of electric dielectric test machine.
For technical solution problem, solution of the present utility model is:
A kind of clamping centralising device of electric dielectric test machine is provided, comprise the nested ring seat of centering fixed frame, rocker bar bearing and support, the vertical bar of bracing frame and bracing frame cross bar, described centering fixed frame bottom offers cavity, this cavity inner wall bottom is provided with and supports nested ring seat, and support the worn-out mouth edge, bottom that nested ring seat extends to cavity, the nested ring seat of described support has been nested with rocker bar bearing, this rocker bar bearing can along central shaft to sliding up and down, and the xsect of described cavity, rocker bar bearing is all rounded; It is hinged with two vertical bars of bracing frame of the left and right sides respectively that support frame as described above cross bar is horizontally through the intercommunicating pore established in centering fixed frame; Described rocker bar bearing outer end is provided with bar threaded hole, and for clamping the bar of centering nested encryptions testing machine, the axial length of the nested ring seat of described support, the degree of depth of cavity are all less than the axial length of rocker bar bearing.
In the utility model, by circular abutment ring nested encryptions between support frame as described above cross bar and the vertical bar of bracing frame, to realize being free to slide up and down of bracing frame cross bar on the vertical bar of bracing frame.
Compared with prior art, the beneficial effects of the utility model are:
Utilize this utility model device, apply two clamping centralising devices accordingly, the bar of testing machine is threaded by bar threaded hole, then bracing frame cross bar, the vertical bar of bracing frame is free to slide, make upper and lower two clamping centralising devices carry out accurate centering, its bar installation process is fast and convenient, no matter is Parallel misalignment, drift angle misaligns or mix the situation of misaligning, the equal automatic centering that can realize sample, improves test figure accuracy.
