Abstract
The utility model relates to measuring equipment. The diameter straight rule mainly comprises two measuring balls, two measuring pins, two screws, a rule holder, copper sheets and a rule body, wherein the two measuring pins are installed on the rule holder; the other ends of the two measuring pins are connected with the two measuring balls; the rule body is installed in the rule holder; and the two screws tighten the rule body through the copper sheets. The two measuring balls are exactly symmetrical with the side surfaces of one side, with scales, of the rule body. When the diameter straight rule in use, the two measuring balls of the diameter straight rule are simultaneously and closely leaned to an inner hole surface of a sleeve part, the two screws are firstly loosened, the rule body moves longitudinally, the lower surface at the lower end of the rule is contacted with the end surface of the sleeve part, and then the two screws are screwed up, so that a marking awl can be used for marking a line on the end surface of the sleeve part along the side, with the scales, of the rule body. The diameter straight rule has a reasonable structure, and is convenient to operate and high in marking precision.
Description
Technical field
The utility model relates to the measurement equipment, and particularly a kind of end face at the major diameter cover parts is enterprising to make things convenient for the accurately diameter marking-out rule of line when passing through the setting-out of Circularhole diameter direction.
Background technology
In production practices, often need line, when needing large-sized measurer during the setting-out of Circularhole diameter direction enterprising the passing through of the end face of major diameter cover parts, neither handled easily line precision is not high yet, goes back the more satisfactory product of neither one and can satisfy this demand on the engineering.
Summary of the invention
In order to address this problem, the utility model provides a kind of diameter marking-out rule, can allow the user make things convenient for, accurately rule.
The technical scheme that the utility model adopted is:
Described diameter marking-out rule mainly constitutes by measuring ball, measurement pin, screw, chi frame, copper sheet and ruler, two described measurement pin are housed on the described chi frame, the other end of two described measurement pin respectively connects a described measurement ball respectively, described ruler is packed in the described chi frame, and two described screws hold out against described ruler by described copper sheet.Two described measurement balls are just about the side symmetry of the graduated side of described ruler.During use two described measurement balls of described diameter marking-out rule are abutted against simultaneously the bore area of cover parts, unclamp two described screws earlier, move up and down described ruler, the lower surface of the lower end of described ruler is contacted with the end face of cover parts, tighten two described screws then, just can rule on the end face of cover parts along the side of the graduated side of described ruler with scriber.
The beneficial effects of the utility model are:
Described diameter marking-out rule is rational in infrastructure, easy to operate, line precision height.
Description of drawings
Further specify below in conjunction with figure of the present utility model:
Fig. 1 is the structural representation of described diameter marking-out rule.
Fig. 2 is the structural representation of the amplification of described chi frame.
Among the figure, 1. measure ball, 2. measure pin, 3. screw, 4. chi frame, 5. copper sheet, 6. ruler.
Embodiment
Described diameter marking-out rule mainly constitutes by measuring ball (1), measurement pin (2), screw (3), chi frame (4), copper sheet (5) and ruler (6), two described measurement pin (2) are housed on the described chi frame (4), the other end of two described measurement pin (2) respectively connects a described measurement ball (1) respectively, described ruler (6) is packed in the described chi frame (4), and two described screws (3) hold out against described ruler (6) by described copper sheet (5).Two described measurement balls (1) are just about the side symmetry of the graduated side of described ruler (6).During use two described measurement balls (1) of described diameter marking-out rule are abutted against simultaneously the bore area of cover parts, unclamp two described screws (3) earlier, move up and down described ruler (6), the lower surface of the lower end of described ruler (6) is contacted with the end face of cover parts, tighten two described screws (3) then, just can rule on the end face of cover parts along the side of the graduated side of described ruler (6) with scriber.
Claims (1)
1. diameter marking-out rule, mainly constitute by measuring ball, measurement pin, screw, chi frame, copper sheet and ruler, it is characterized in that: two described measurement pin are housed on the described chi frame, the other end of two described measurement pin respectively connects a described measurement ball respectively, described ruler is packed in the described chi frame, two described screws hold out against described ruler by described copper sheet, and two described measurement balls are just about the side symmetry of the graduated side of described ruler.
