Specific embodiment
As shown in Figure 1, 2, a kind of pull force tester, including base 14, lever 10 and the workpiece being arranged on base 14
Bearing 1, work mounting s 3, cylinder 6, lever supporting 7 and lever support 8, workpiece support 1 are fixed on the left end middle part of base 14, work
The horizontally disposed hinged seat I15 of the right-hand member of part bearing 1, lever 10 is movably arranged on the right-hand member of base 14, the lever 10 and ground
Face be horizontally disposed with, the length direction of lever 10 is vertical with the length direction of base 14, on lever 10 with workpiece support 1 on be hinged
The relative positions of seat I15 set hinged seat II11, hinged seat I15 and hinged seat II11 in same level, the edge of work mounting s 3
The length direction of base 14 is uniformly arranged between workpiece support 1 and lever 10, and the thick stick of support lever 10 is provided under lever 10
Bar supporting 7, lever support 8 and cylinder 6 are separately positioned on the right-hand member of base 14 position corresponding with the rear and front end of lever 10, thick stick
The front end of bar 10 is hinged by centrepin I9 with lever support 8, and the rear end of lever 10 passes through the output of centrepin II12 and cylinder 6
End is hinged, and the input of cylinder 6 is provided with the pipeline 13 for being connected with ground wind regime, and the He of operation valve 4 is provided with pipeline 13
Pressure gauge 5.
Cylinder 6 in the utility model can be substituted by hydraulic cylinder, and pull test is carried out to workpiece 2 using the utility model
When, the two ends of workpiece 2 respectively with workpiece support 1 on hinged seat I15 and lever 10 on hinged seat II11 be hinged, to protect
Card workpiece 2 is not received additional bending moment by pulling force.Three pitch of holes ratios of the utility model lever 10（That is centrepin I9 and hinged seat
The ratio of the distance between the distance between II11 and hinged seat II11 and centrepin II12）, cylinder（Or hydraulic cylinder）6 internal diameter
The pulling force that can be needed according to workpiece 2 with in-cylinder pressure is pre-set, and the different ratios of lever 10 are to cylinder（Or hydraulic pressure
Cylinder）The enlargement ratio of thrust is different.
The utility model is by cylinder（Or hydraulic cylinder）Lever is promoted, indirect pull test is carried out to workpiece by lever.Tool
The job order of body is：Open and manipulate valve 4, with ground wind regime（Or hydraulic oil container）The input pressure air of pipeline 13 of connection（Or
Hydraulic oil）, into cylinder（Or hydraulic cylinder）6, promote lever to be turned out around centrepin I9, the lever 10 of rotation is to workpiece
