The implication of Reference numeral among the figure: 1, slide block, 2, support, 3, balancing weight, 4, drive cylinder, 5, mounting bracket, 6, hanging wire, 7, detecting head, 8, the tensioning suspender, 9, web member, 10, the air supporting piece, 11, butt strip, 12, piston rod.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.
Referring to Fig. 1 and Fig. 2, the Z axle test structure of three-dimensional tester that is applicable to of the present invention comprises: be used for fixing Z axle test structure and the slide block that can slide in the horizontal direction, be fixed on slider top support, be installed on the slide block and at the transportable balancing weight of vertical direction, be used to drive the driving cylinder that balancing weight moves.Shape after balancing weight is blocked by horizontal plane is preferably rectangle.
Since be Z axle test structure, will guarantee that it is in accurate Z Spindle Status, and can not squint, could guarantee test accuracy like this.Balancing weight is exactly in order to realize this purpose; Guarantee that it keeps vertical under action of gravity; In order to reach better effect; Slide block is provided with two different mounting brackets of present position height, the mounting shaft (not shown, as promptly to be the zone that the middle confession balancing weight that forms of mounting bracket passes) that the mounting bracket stroke has the confession balancing weight of coincidence vertically to pass; Balancing weight is suspended in the mounting shaft through the hanging wire that the top is fixed on a top of the trellis, and is provided with detecting head in the bottom of balancing weight, is used to carry out the test of Z axle.
Drive the vertical both sides of cylinder and be provided with the tensioning suspender, drive cylinder and be suspended between two mounting brackets through the tensioning suspender, the piston rod that drives cylinder is fixedly connected with balancing weight.As a kind of preferred version, piston rod and balancing weight make together fixed to one another through a web member.So, be subjected to displacement in Z-direction through driving web member drive balancing weight, carry out the position adjustments of Z axle, to adapt to actual testing requirement thereby drive cylinder.
In order to guarantee that further balancing weight is in vertical direction and balancing weight and does not have frictionally and move up and down, the mounting shaft correspondence is provided with a plurality of air supporting pieces towards the position of the sidewall of balancing weight.When the air supporting piece is carried same air pressure, the air supporting piece applies same atmospheric pressure from each side of balancing weight to balancing weight, can not have frictionally and moves at vertical direction.
As further improvement, drive the butt strip that the tensioning suspension of cylinder top extends upward and formation can be blocked above-mentioned cantilever tip in the end.When cylinder was in relaxation state, butt strip was taken the top of support, made detecting head can not touch the test platform of tester, played the effect of protection detecting head.
More than show and described ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand, and the foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
