Abstract
A positioning fixture for measuring roundness of cylinders comprises an L-shaped base. The inner side of a vertical arm of the base is provided with a vertical slide and a transverse slide. The transverse slide is made right above the vertical slide. The vertical slide and the transverse slide are slidably connected with a first slider and two second sliders respectively. Each slider is provided with a cambered surface. The cambered surfaces of the two second sliders face to each other. The cambered surface of the first slider faces up. Each slider is provided with a first longitudinal fastening screw. A roundness measuring instrument is fixedly connected to a horizontal arm of the base. A probe of the roundness measuring instrument extends down out of the horizontal arm. The positioning fixture is simple in structure and applicable to positioning and roundness measurement for cylinders different in outside diameter.
Description
Technical field
The present invention relates to technical field of tooling clamps, relate in particular to a kind of positioning tool while measuring for cylinder roundness of external circle.
Background technology
Cylinder circularity, refers to that the xsect of cylinder approaches the degree of theoretical circle, and the difference of maximum radius and least radius, is used roundness measuring equipment to measure conventionally.Though general positioning tool can position it, same secondary positioning tool can only be applicable to location and the roundness measurement of same external diameter cylinder, makes the scope of application of frock limited.
Summary of the invention
The present invention is directed to above-mentioned shortcoming of the prior art, a kind of cylinder roundness measurement positioning tool is provided, it is simple in structure, can be applicable to the roundness measurement of various outer diameter cylinder, and location is reliable, and flexible and convenient to use.
The technical solution adopted in the present invention is as follows:
Cylinder roundness measurement positioning tool, comprise pedestal, pedestal is inverted L-shaped structure, and the inner side of the vertical arm of pedestal has vertical chute and horizontal concrete chute, horizontal concrete chute be positioned at vertical chute directly over, vertical chute slidably connects slide block one, horizontal concrete chute slidably connects two slide blocks two, and slide block one and slide block two are all with an arcwall face, and the described arcwall face of two slide blocks two is relative, the arcwall face of slide block one, is equipped with a longitudinal holding screw one upward on slide block one and slide block two; On the horizontal arm of pedestal, be connected with roundness measuring equipment, and the probe of roundness measuring equipment stretches out horizontal arm downwards.
The invention has the advantages that: by horizontal concrete chute, vertical chute and three structures with the slide block of arcwall face, arrange, by three arcwall faces of three slide blocks, formed the space, location of cylinder to be measured, can by three slide blocks that slide, regulate according to the external diameter size of cylinder to be measured the size in the space, location of accommodating cylinder to be measured, the scope of application that has expanded thus positioning tool of the present invention and used the roundness measuring device of this positioning tool, and accurate positioning is reliable, has guaranteed positioning precision; By motionless, the to be measured cylinder workpiece of roundness measuring equipment, rotate, can realize the measurement of the roundness of external circle of cylinder workpiece to be measured, measure quick, simple.Tool structure of the present invention is simple, flexible and convenient to use.
Accompanying drawing explanation
Fig. 1 is stereographic map of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the present invention includes pedestal 1, pedestal 1 is inverted L-shaped structure, the inner side of the vertical arm 101 of pedestal 1 have vertical chute 102 and with horizontal concrete chute 103, horizontal concrete chute 103 be positioned at vertical chute 102 directly over, vertical chute 102 slidably connects slide block 1, horizontal concrete chute 103 slidably connects two slide blocks 2 105, slide block 1 and slide block 2 105 are all with an arcwall face, the described arcwall face of two slide blocks 2 105 is relative, the arcwall face of slide block 1 upward, sliding slider 1 and slide block 2 105, make described three arcwall faces surround the space, location of cylinder to be measured, on slide block 1 and slide block 2 105, be equipped with a longitudinal holding screw 2, on the horizontal arm 106 of pedestal 1, be connected with roundness measuring equipment 3, and the probe of roundness measuring equipment 3 stretches out horizontal arm 106 downwards.
Using method of the present invention is as follows:
Location: sliding slider 1 and slide block 2 105, make described three arcwall faces surround the space, location of cylinder to be measured, by cylinder workseat to be measured on the described arcwall face of slide block 1, by sliding slider 1, make cylinder workpiece to be measured be positioned at the sensing range of roundness measuring equipment 4 probes, and by longitudinal holding screw 2, slide block 1 is held out against on the surface of vertical chute 102, again by sliding slider 2 105, adjusting makes the described arcwall face of two slide blocks 2 105 be pressed on the periphery of cylinder workpiece to be measured, and with longitudinal holding screw 2, two slide blocks 2 105 are held out against on the surface of horizontal concrete chute 103, thus cylinder workpiece to be measured is positioned in the space, location that described three arcwall faces surround,
Measure: after cylinder workpiece to be measured location puts in place, by cylinder workpiece to be measured is rotated a circle, the demonstration of observing roundness measuring equipment 3 changes, and record data, thus, can measure the circularity of tested periphery, repeated measurement, can draw circularity mean value, thus, complete the measurement of circularity.
Because positioning tool of the present invention can regulate according to the external diameter size of cylinder the size in the space, location of accommodating cylinder to be measured thereby the scope of application that has expanded positioning tool of the present invention and used the roundness measuring device of this positioning tool.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
