Abstract
The invention discloses a caliber rule for measuring pitch diameter of threads. The caliber rule comprises a rule body with scales, a vernier moving on the rule body and a fixed claw connected with the vernier, wherein one end part of the rule body is provided with a square hole; an adjustable telescopic claw is inserted into the square hole and is adjusted through a locking bolt on the rule body; and one end part of the adjustable telescopic claw is connected with a semispherical gage head corresponding to a semispherical gage head of the vernier fixed claw. The caliber rule adopts the adjustable telescopic claw to overcome the disadvantage that two measuring points are not in the same plane, and can exactly measure the pitch diameter of the threads when combined with the characteristics of the semispherical gage heads. Moreover, the caliber rule has the advantages of simple and light structure, high measuring accuracy and low production cost.
Description
Technical field
The present invention relates to a kind of survey instrument of measuring the pitch diameter of thread.
Background technology
When machining cylinder or taper pipe thread, what adopted in the footpath in measuring in the past is internal and external threads tooth rule and screw-thread micrometer, and operation is heavy, complexity, and measurer price comparison costliness.
Summary of the invention
The object of the present invention is to provide a kind of survey instrument of measuring convenience, accuracy height, the measurement pitch diameter of thread that cost is low.
The present invention takes following technical scheme to realize: the slide calliper rule of this measurement pitch diameter of thread comprise a blade that has scale, a vernier that is displaced on the blade, the fixed claw that links to each other with vernier, blade one end has square opening, adjustable extendible and retractable dog inserts in the square opening, tighten the regulation and control of lock screw by blade, it is corresponding with the semisphere gauge head of vernier fixed claw that adjustable extendible and retractable dog one end is associated with the semisphere gauge head, on the vernier digital display screen can be set, the semisphere gauge head is by a cylinder, cone links to each other with cylinder, the semi-round ball that is provided with in a hole and the patchhole from the centrum tip constitutes.
The present invention mainly adjustable extendible and retractable dog of employing activity overcomes because two measurement points defective on same surface level not in conjunction with semisphere gauge head characteristics, can be measured the pitch diameter of thread accurately; The present invention is simple in structure, light, accuracy of measurement is high, and it is low to produce the cost of this product.

Embodiment
The present invention is described in further detail in conjunction with the accompanying drawings.
From Fig. 1, Fig. 2, Fig. 3 as can be seen, the slide calliper rule of this measurement pitch diameter of thread comprise that a blade that has a scale 1, one are displaced into the vernier 2 on the blade, the fixed claw 3 that links to each other with vernier, blade one end has square opening 4, adjustable extendible and retractable dog 5 inserts in the square opening, tighten the regulation and control of lock screw 6 by blade, it is corresponding with the semisphere gauge head 8 of vernier fixed claw that adjustable extendible and retractable dog 5 one ends are associated with semisphere gauge head 7.On the vernier 2 the digital display screen can be set, semisphere gauge head 7,8 by a cylinder, link to each other cone with cylinder, the semi-round ball that is provided with in a hole and the patchhole from the centrum tip constitutes.
During measurement, at first the fixed claw on the vernier 23 is inserted in the screw thread of being surveyed, regulate adjustable extendible and retractable dog 5 then, make the semisphere gauge head 8 on the fixed claw 3 corresponding with the semisphere gauge head 7 on the adjustable extendible and retractable dog 5, tight lock screw 6 stationary adjustable extendible and retractable dog 5, making adjustable extendible and retractable dog 5 is one with blade, regulates vernier 2, can accurately measure the middle footpath of screw thread like this.
Claims (3)
1, a kind of slide calliper rule of measuring the pitch diameter of thread comprise that a blade (1) that has a scale, one are displaced into the vernier (2) on the blade, the fixed claw (3) that links to each other with vernier, is characterized in that:
Blade one end has square opening (4), and adjustable extendible and retractable dog (5) inserts in the square opening, tightens lock screw (6) regulation and control by blade, and it is corresponding with the semisphere gauge head (8) of vernier fixed claw that adjustable extendible and retractable dog (5) one ends are associated with semisphere gauge head (7).
2, a kind of slide calliper rule of measuring the pitch diameter of thread according to claim 1 is characterized in that:
Vernier can be provided with the digital display screen on (2).
3, a kind of slide calliper rule of measuring the pitch diameter of thread according to claim 1 is characterized in that:
Semisphere gauge head (7,8) by a cylinder, link to each other cone with cylinder, the semi-round ball that is provided with in a hole and the patchhole from the centrum tip constitutes.
