Abstract
A vernier caliper for measuring a groove in a deep hole comprises a blade outer measuring jaw (1), a caliper frame (2), a tightening bolt (3), a caliper body (4), a main scale (5), a lower measuring jaw (6), a vernier scale (7) and a vernier device (8). An elongation section (11) is arranged at the lower end of the lower measuring jaw (6), bolt holes (12) are coaxially symmetrically formed on the two sides of the bottom of the elongation section, bolt measuring heads (9) are respectively screwed on the two sides of the bottom of the elongation section, and tightening bolt caps (10) are screwed on the bolt measuring heads (9). The vernier caliper provided by the utility model has compact structure, is simple and practical, and can conveniently measure the diameter of the part inner groove with high requirement for tolerance, small caliber and large inner depth.
Description
Technical field
The utility model relates to a kind of vernier caliper of measuring the deep hole internal channel.
Background technology
In modern equipment manufacture process, tolerance dimension for part is had relatively high expectations, adopt general general vernier caliper measurer to be difficult to the deep hole internal diameter of workpiece is accurately detected, the operator is difficult to guarantee the accurate to dimension of workpiece usually in the process of this type of part of processing, especially in measuring the big deep hole internal channel process of little, the interior dark abdomen of bore, the efficient that adopts existing vernier caliper measurer to measure is extremely low, has both influenced the quality of product, incurs loss through delay processing progress again.Though, the measurer of special measurement deep hole internal channel is also arranged, price is too high, quick abrasion, serviceable life is also low.
Summary of the invention
In order to overcome the existing big deep hole internal channel above shortcomings part of little, the interior dark abdomen of bore of measuring, the utility model provide a kind of simple in structure, easy to operate, measure accurately, the vernier caliper of the measurement deep hole internal channel of long service life.
The purpose of this utility model is to adopt following technical scheme to realize.
A kind of vernier caliper of measuring the deep hole internal channel comprises the outer measuring jaw of the edge of a knife, chi frame, trip bolt, blade, main scale, following measuring jaw, vernier scale, inching gear; Be provided with an extension in following measuring jaw lower end, offer screw in extension two bottom sides concentric symmetry, and be rotary with the bolt measuring head respectively, on the bolt measuring head, be rotary with fastening nut.
The beneficial effects of the utility model are: owing to adopt technique scheme, make certain improvements on the basis of original traditional vernier caliper, make whole apparatus structure simple, easy to operate; Can adjust needed size according to the requirement of hole size in the tested part, not only prolong the serviceable life of slide calliper rule but also guaranteed the accuracy of measuring; Make it can guarantee that vernier caliper measurement deep hole internal channel meets the requirement of national verification rules, these slide calliper rule are examined and determine after using one-period once more, slide calliper rule stability of display is better, can guarantee that measuring accuracy is accurate, reliable and can satisfy parts measurement requirement in the production and processing preferably, can satisfy production requirement again.
Further set forth the utility model content below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, the outer measuring jaw of the 1-edge of a knife; 2-chi frame; The 3-trip bolt; The 4-blade; The 5-main scale; Measuring jaw under the 6-; The 7-vernier scale; The 8-inching gear; 9-bolt measuring head; The 10-fastening nut; The 11-extension; The 12-screw.
Embodiment
See Fig. 1, a kind of vernier caliper of measuring the deep hole internal channel of the utility model comprises the outer measuring jaw 1 of the edge of a knife, chi frame 2, trip bolt 3, blade 4, main scale 5, following measuring jaw 6, vernier scale 7, inching gear 8.Be provided with an extension 11 in following measuring jaw 6 lower ends, offer screw 12 in extension two bottom sides concentric symmetry, and be rotary with bolt measuring head 9 respectively; On bolt measuring head 9, be rotary with fastening nut 10.
The utility model embodiment transforms existing vernier caliper, and extension 11 is selected for use tool steel material of the same race to weld with following measuring jaw 6 to be connected, and can adopting between the two when weldering connects, the concaveconvex structure piece is formed by connecting.At the screw 12 that extension 11 two bottom sides symmetries are offered, both can offer and be open-work, also can offer and be closed pore, aperture, two holes is identical.Adopt two bolt measuring heads 9 that match to screw in screw 12 respectively, reserve one section separately as measuring head; With fastening nut 10 bolt measuring head 9 is tightened then; External part in extension 11 two bottom sides is the measuring head that is used for measuring deep hole.These bolt measuring head 9 left side sections are connected with the side of fixing of following measuring jaw 6, and right section is connected with activity one side of following measuring jaw 6.When measuring workpieces deep hole internal diameter, moving cursor chi 7, right section bolt measuring head 9 moves with vernier scale 7, makes left and right bolt measuring head 9 form certain distance, when two bolt measuring heads 9 lean the measured hole inwall separately, this distance is to need the hole internal diameter measured.The length of extension 11 is looked the specification size of vernier main scale 5, also considers the influence of the issuable dynamometry distortion of extension to measuring accuracy, and for common hand-held vernier caliper, generally can prolong distance is 30～60mm.And the length of bolt measuring head 9 is corresponding definite according to the degree of depth of tested measuring tank, and for common hand-held vernier caliper, the scope that generally can be chosen in 4mm～60mm all can.It is identical usually that the bolt measuring head 9 that is positioned at both sides stretches out segment length, and this stretches out the bolt measuring head that segment length can be changed another group length as required simultaneously.In case extension elongation is determined, adopts fastening nut 10 to screw in bolt measuring head 9 to the extension sidewall, and bolt measuring head 9 is fixing.
When using the utility model vernier caliper measurement, at first slide calliper rule are carried out 0 bit correction, according to the measured workpiece requirement, gauge head is of a size of integer in adjusting, move vernier scale 7 during measurement, the bolt measuring head 9 at extension two ends is leaned the measured hole inwall, and the actual read number that will measure slide calliper rule then adds measuring jaw up and down to 0 o'clock physical size, is the size of measured object.
