Abstract
The invention provides a vernier caliper which comprises a main ruler which is provided with a left clamp and a right clamp. The end part of the left clamp is rotatingly connected to the main ruler through a pin shaft. The end part of the left clamp is provided with a pointer which is perpendicular to the end part of the left clamp. The end part of the left clamp is also provided with a first tightening screw. When the left clamp rotates around the pin shaft to an appropriate position, the position of the left clamp can be fixed through the first tightening screw. A curved scale is arranged above the pointer and is on the main ruler. The curved scale is marked with angle values, and a zero scale is in the middle. The right clamp is provided with a cursor, and the right clamp is fixed to the main ruler through a second tightening screw. According to the vernier caliper, a problem that an existing vernier caliper is inconvenient to measure a large shaft type component and taper of a cone can not be measured can be solved.
Description
Technical field
The invention belongs to survey tool field, and in particular to a kind of slide measure for dimensional measurement, more particularly to a kind of big profile shaft of cement industry, hole type parts and the part with taper measurement.
Background technology
Slide measure is a kind of measuring appliance, it is generally used to measure the external diameter of axle, internal diameter and the depth in hole, but the slide measure of current people, because measurement bar is shorter and can not elongate, therefore for thicker axle, the situation that slide measure range is enough but measurement bar is too short and cannot measure often occurs；In addition, traditional slide measure is only used for measuring the depth in internal-and external diameter and hole, acts on single.
The content of the invention
The technical problems to be solved by the invention are directed to above-mentioned the deficiencies in the prior art, and a kind of cable slide measure for providing, it can solve the problems, such as existing slide measure inconvenience measurement macrotype axes series parts and cannot measure cone taper.
The object of the present invention is achieved like this：
A kind of slide measure, it is provided with left card and right card including main scale main scale, the end of left card is connected with main scale by bearing pin rotary type, left card end is provided with pointer, pointer is mutually perpendicular to the end of left card, left card end is additionally provided with the first holding screw, when left card rotates to correct position around bearing pin, left card position can be fixed by the first holding screw, curved scale is provided with above pointer and on main scale, curved scale is marked with angle value, and center is zero groove, right card is provided with vernier, is fixed by the second holding screw and main scale.
The left card and right card are formed by connecting by fix bar, measurement bar and at least one expansion link respectively.
The expansion link nested type is connected and composed, and expansion link insertion fix bar is simultaneously fastened by the 3rd holding screw, and measurement bar insertion expansion link is simultaneously fastened by the 4th holding screw.
The measurement bar lower end is provided with measuring claw, and the section of measuring claw is isosceles triangle.
When the pointer points to zero groove on curved scale, left card is vertical with main scale, and now sliding vernier is adjacent to two measuring claws, and zero groove on vernier needs to align with zero groove on main scale.
The maximum length that the left card and right OK a karaoke club go out should be not less than the half of slide measure range.
By measuring claw Cross section Design into isosceles triangle so that for face is tangent with cylindrical during measurement external diameter or male cone (strobilus masculinus), for line is contacted with endoporus during measurement internal diameter or inner conical surface, so as to reduce measurement error.
Left card and right card are designed to Collapsible structure, so when external diameter is surveyed, according to the size of object under test diameter, the length of expansion link is adjusted, the usage range of the present apparatus has effectively been expanded；The maximum length that left card and right OK a karaoke club go out in addition should be not less than the half of slide measure range, be that, in order to ensure in range ability, measuring claw can be stretched at the maximum diameter of axle of surveyed axle.
Using said structure, when needing to survey the taper of outer cone or inner circle taper hole, rotate left card and slide right card, centrum side is allowed to be adjacent to right card measuring claw, opposite side is adjacent to left card measuring claw, the angle value on curved scale is read, so as to obtain the taper of centrum by the relevant knowledge of trigonometric function.
When the measurement diameter of axle or aperture is needed, rotating left card makes pointer point to the groove of curved scale zero, and tightens the first holding screw, it is ensured that left card is vertical with main scale, then left card is reached into appropriate length with right OK a karaoke club, then slides vernier and the diameter of axle or aperture are measured.

The invention will be further described with reference to the accompanying drawings and examples：
Fig. 1 is structural representation of the invention；
Fig. 2 is the design sketch that the present invention surveys taper；
Fig. 3 is the design sketch that the present invention surveys the diameter of axle；
Fig. 4 is the sectional view of measuring claw of the present invention.
Specific embodiment
A kind of slide measure, it includes main scale 1, and main scale 1 is provided with left card 2 and right card 3, it is characterised in that：The end of the left card 2 is connected with main scale 1 by the rotary type of bearing pin 14,2 ends of left card are provided with pointer 13, pointer 13 is mutually perpendicular to the end of left card 2,2 ends of left card are additionally provided with the first holding screw 15, when left card 2 rotates to correct position around bearing pin 14,2 positions of left card can be fixed by the first holding screw 15, curved scale 12 is provided with above pointer 13 and on main scale 1, curved scale is marked with angle value, and center is zero groove, right card 3 is provided with vernier 4, is fixed by the second holding screw 5 and main scale 1.
, respectively by fix bar 6, the expansion link 7 of measurement bar 8 and at least one is formed by connecting for the left card 2 and right card 3.
The expansion link nested type is connected and composed, and expansion link insertion fix bar is simultaneously fastened by the 3rd holding screw 10, and measurement bar insertion expansion link is simultaneously fastened by the 4th holding screw 11.
The measurement bar lower end is provided with measuring claw 9, and measuring claw need to be finished makes surface smooth, and section is isosceles triangle.
When the pointer 13 points to zero groove on curved scale 12, left card 2 is vertical with main scale 1, and now sliding vernier 4 is adjacent to two measuring claws 9, and zero groove on vernier needs to align with zero groove on main scale.
The maximum length that the left card 2 and right card 3 are pulled out should be not less than the half of slide measure range.
By measuring claw Cross section Design into isosceles triangle so that for face is tangent with cylindrical during measurement external diameter or male cone (strobilus masculinus), for line is contacted with endoporus during measurement internal diameter or inner conical surface, so as to reduce measurement error.
