Description
Technical field
The oil hydraulic cylinder test that the present invention relates to the type approval test being applicable to various oil hydraulic cylinder connects dolly.
Background technique
It is relative with tested cylinder connecting tooling structure simple that existing cylinder bench loads cylinder, is usually all to form four-bar linkage structure or linear structure, such as vertical test stand stand by connecting tooling and oil cylinder and stand, and straight line type is to pushing up mechanism.Vertical test stand stand requires that its structure is quite firm, otherwise cannot bear the thrust of tested cylinder, and there is certain potential safety hazard.And straight line type only plays to top mechanism connection set the effect of being connected and fixed here, do not give play to the function that it is larger.
Summary of the invention
Object of the present invention is just to provide one and replaces original lining by joint shaft bearing, increase return pulley bearing, return pulley installation shaft, side wheel bearing, side wheel installation shaft etc. simultaneously, while ensureing that dolly realizes cylinder connecting device, joint shaft bearing can ensure that oil cylinder has certain degrees of freedom in running; The part of tested cylinder and loading cylinder can make a concerted effort to be delivered on test stand pedestal by return pulley bearing, improves the stability of test stand; The side wheel bearing of dolly limits the offset distance of tested cylinder, is measured the oil hydraulic cylinder test connection dolly of lateral load by foil gauge simultaneously.
Solution of the present invention is such:
A kind of oil hydraulic cylinder test connects dolly, and vehicle frame is provided with the sliding pair be slidably connected that to be in line with stand mesa-shaped, and described vehicle frame is provided with joint shaft bearing for connecting tested cylinder and for being connected the oil hydraulic cylinder fitting seat loading cylinder.
Technological scheme also comprises more specifically: described sliding pair refers to: described vehicle frame both sides are provided with return pulley installation shaft and are installed on the return pulley bearing of return pulley installation shaft, and described return pulley bearing connects with the linear ramp bottom surface of stand platform and the part of making a concerted effort loading cylinder and tested cylinder is delivered to the sliding pair of stand platform base.
Further: described sliding pair refers to: to be provided with side wheel installation shaft at described bottom of frame and to be installed on the side wheel bearing of side wheel installation shaft, described side wheel bearing connects with the linear ramp side of stand platform and is construed as limiting because axis misaligns the sliding pair of produced skew.
Further: described side wheel bearing and stand platform linear ramp contacts side surfaces face are provided with foil gauge for measuring lateral load.
Advantage of the present invention replaces original lining by joint shaft bearing, increase return pulley bearing, return pulley installation shaft, side wheel bearing, side wheel installation shaft etc. simultaneously, while ensureing that dolly realizes cylinder connecting device, the part of tested cylinder and loading cylinder can make a concerted effort to be delivered on test stand pedestal by return pulley bearing, improves the stability of test stand; The side wheel of dolly limits the left and right skew of tested cylinder; Joint shaft bearing can ensure that oil cylinder has certain degrees of freedom in running.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the structural representation of the present invention when side wheel bearing 4 is positioned at limit on the right-right-hand limit when being connected with stand platform.
Fig. 4 is the structural representation of the present invention when side wheel bearing 4 is positioned at limit on the left when being connected with stand platform.
Fig. 5 is that the present invention and stand platform use schematic diagram for connection during test fluid cylinder pressure.
In figure, each parts detail is: joint shaft bearing 1, side wheel bearing 2, side wheel installation shaft 3, return pulley bearing 4, return pulley installation shaft 5, vehicle frame 6, oil hydraulic cylinder fitting seat 7, stand platform 8, tested cylinder 9, loading cylinder 10,11 fitting seat.
Embodiment
As shown in Figure 1, vehicle frame 6 is provided with the sliding pair forming linear slide with stand platform 8 and be connected, and described vehicle frame is provided with joint shaft bearing 1 for connecting tested cylinder 9 and for being connected the oil hydraulic cylinder fitting seat 7 loading cylinder 10.
In structure shown in Fig. 1, two sliding pair are provided with between vehicle frame and stand platform, a sliding pair described vehicle frame both sides is provided with return pulley installation shaft 5 and is installed on the return pulley bearing 2 of return pulley installation shaft, and described return pulley bearing 2 connects with the linear ramp bottom surface of stand platform and the part of making a concerted effort loading cylinder and tested cylinder is delivered to the sliding pair of stand platform base; Another sliding pair is that described sliding pair refers to: be provided with side wheel installation shaft 3 at described bottom of frame and be installed on the side wheel bearing 4 of side wheel installation shaft, and described side wheel bearing 4 connects with the linear ramp side of stand platform and is construed as limiting because axis misaligns the sliding pair of produced skew.
Described side wheel bearing 4 is provided with foil gauge for measuring lateral load with stand platform linear ramp contacts side surfaces face.
When the present invention uses, joint shaft bearing 1 is arranged in oil hydraulic cylinder fitting seat 7 earrings of left end, and the oil hydraulic cylinder fitting seat 7 of right-hand member is fixed on vehicle frame 6, tested cylinder 9, loading cylinder 10 is installed by shown in Fig. 5.
When oil hydraulic cylinder is tested, load cylinder as load, tested cylinder back and forth runs under working pressure.Tested cylinder is connected with joint shaft bearing 1 by bearing pin, and tested cylinder has certain degrees of freedom in running, can change for different oil hydraulic cylinders to oil hydraulic cylinder fitting seat 7.The part of making a concerted effort loading cylinder and tested cylinder is delivered to stand pedestal by return pulley bearing 2, improves the global stability of bed stand, the sliding friction of linarity to top is become rolling friction simultaneously, reduces system energy loss and is connected dolly wearing and tearing.Side wheel bearing 4 can limit because axis misaligns produced skew, and if Fig. 3 is the state being displaced to limit on the right-right-hand limit, Fig. 4 is the state being displaced to limit on the left; Can stick on foil gauge to baffle plate measures lateral load simultaneously.
Above-mentioned explanation is not to reality of the present invention, and the present invention is also not limited to above-mentioned citing, those skilled in the art, the change made within the scope of the invention, changes and adds or replace, and all should belong to protection scope of the present invention.
