Abstract
The invention relates to the field of measuring instruments, in particular to a flatness measuring instrument which comprises a lintel. A through hole is formed in the middle of the lintel, a measuring meter is slidably arranged in the through hole, the lower end of the measuring meter is provided with a measuring pin contacting with a measured plane, screw holes corresponding to two sides of the through hole are formed in the lintel, one screw hole is formed in a small end of the lintel, two screw holes are formed in a large end of the lintel, the connecting line of the two screw holes in the large end is parallel to the side line of the large end of the lintel, an adjusting screw is arranged in each screw hole, and a ceramic ball is arranged at the lower end of each adjusting screw. The flatness measuring instrument is simple, reasonable and ingenious in structure and low in manufacturing cost, and is simple to operate when the flatness of a panel is measured. A standard panel is firstly used for performing zero setting on the flatness measuring instrument, and then the flatness measuring instrument is placed on the panel to be measured, so that the flatness of the panel to be measured can be rapidly and conveniently read.
Description
Technical field
The present invention relates to the surveying instrument field, specifically a kind of flatness measuring instrument.
Background technology
Between bearing face mill manufacturing procedure, for bearing ring, the plane of lasso is as the reference field of later process, and its flatness is extremely important, if face is not whole for the flatness of bearing ring, the precision of later process mill ditch, grinding out, superfinishing can't guarantee.The precondition of milled bearing ring flatness is exactly that the flatness of the emery wheel on equipment and the flatness on chassis will be got well.At present plane of grinding wheel and plane, chassis repair by truing device, if during the rotation center out of plumb of the movement locus of truing device and chassis axle or grinding wheel spindle, repair the plane come with regard to injustice.The measurer of the measurement plane degree that production scene is often used is edge of a knife chi, by edge of a knife chi and plane contact, checks the light leak rate of edge of a knife chi and tested part.If can see that obvious light leak position is exactly sunk position, plane.Whether qualified the method that checks like this flatness is can only qualitative illustrated planar degree, and quantitatively the illustrated planar degree is how many.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of flatness measuring instrument is provided, adopt this measuring instrument can measure the emery wheel of bearing ring process use and the flatness on chassis accurate quantification.
According to technical scheme of the present invention: a kind of flatness measuring instrument, comprise lintel, it is characterized in that: described lintel middle part offers through hole, in through hole, slides and is provided with meter, and the lower end of meter has and the contacted survey pin in tested plane; Offer respectively screw hole corresponding to described through hole both sides on lintel, wherein the small end at lintel offers a screw hole, large end offers two screw holes, and the line of two screw holes of large end is parallel to the large end of lintel sideline, be provided with adjusting screw in each described screw hole, place, lower surface corresponding to lintel on adjusting screw is provided with setting nut, and described adjusting screw bottom is provided with Ceramic Balls.
As a further improvement on the present invention, described lintel is T-shaped shape.
As a further improvement on the present invention, on described adjusting screw, the top corresponding to Ceramic Balls also is provided with a nut.
Technique effect of the present invention is: the present invention is simple and reasonable for structure, ingenious, and manufacturing cost is cheap; Simultaneously the present invention is simple to operate when measuring the flatness of panel, only need be first with the standard panel by the present invention's operation of returning to zero, and then the present invention is positioned on plane to be measured, can read quickly and easily the flatness on this plane to be measured.
The accompanying drawing explanation
Fig. 1 is use view of the present invention.
Fig. 2 is plan structure schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1, Fig. 2, comprise tested plane 1, Ceramic Balls 2, survey pin 3, adjusting screw 4, setting nut 5, lintel 6, meter 7 etc.
As shown in Figure 1, the present invention is a kind of flatness measuring instrument, comprises lintel 6, and described lintel 6 middle parts offer through hole, in through hole, slides and is provided with meter 7, and the lower end of meter 7 has and the contacted survey pin 3 in tested plane 1; Offer respectively screw hole corresponding to described through hole both sides on lintel 6, wherein the small end at lintel 6 offers a screw hole, large end offers two screw holes, and the line of two screw holes of large end is parallel to the large end of lintel 6 sideline, be provided with adjusting screw 4 in each described screw hole, place, lower surface corresponding to lintel 6 on adjusting screw 4 is provided with setting nut 5, and described adjusting screw 4 bottoms are provided with Ceramic Balls 2.
Described lintel 6 is T-shaped shape.
Top corresponding to Ceramic Balls 2 on described adjusting screw 4 also is provided with a nut.
The course of work of the present invention is as follows: at first the present invention is positioned on a standard flat plate, adjust the position of each setting nut 5, meter 7 lower ends are surveyed pin 3 and are placed on the standard flat plate, then the operation of meter 7 being returned to zero, after preliminary work before completing above-mentioned measurement, can be by the present invention for measuring operation, specifically by this practical 1 upper end, tested plane that is placed in, the Ceramic Balls 2 of adjusting screw 4 lower ends is supported on tested plane 1, the survey pin 3 of meter 7 lower ends is placed on tested plane 1, can read the flatness on tested plane 1 by the dial plate on meter 7 tops.
