Abstract
The utility model discloses an adjustable vernier leveling staff, which comprises a frame type level, a vernier caliper and an adjustable supporting rod. The adjustable vernier leveling staff is mainly characterized in that the adjustable supporting rod is installed on the lateral surface of the frame type level, and the vernier caliper is installed on the adjustable supporting through bolts on a fastening part. The adjustable vernier leveling staff matches with a level in use, can resolve the measuring problem of comparatively high precise flatness, is particularly adaptable to measuring flatness of a base with large body, complicated structure, unconnected measuring surfaces, large difference of level of height of each measuring point and high requirement on installation precision.
Description
Technical field the utility model relates to field of measuring technique, relates in particular to a kind of adjustable vernier levelling pole that is used with spirit-leveling instrument.
Before the big-and-middle-sized equipment of background technology is installed, must measure, adjust, find the reference field of each base accurately, to satisfy the installation accuracy requirement to its base plane degree (also being levelness).For the big-and-middle-sized equipment of a plurality of bases, then also to carry out the detection of flatness between each base, adopt spirit-leveling instrument to cooperate detection with levelling pole usually.In measurement, existing levelling pole such as ruler, folding chi, Sopwith staff etc., their scale is divided into two kinds of 1mm or 0.5mm, being that the direct-reading precision is the highest can only be 1mm or 0.5mm, measurement for the following precision of 0.5mm, can only estimate and read, out of true can not satisfy the following degree of precision equipment of 0.5mm installation requirement.
Summary of the invention is at the weak point of above-mentioned existence, and the purpose of this utility model provides a kind of measuring accuracy height, good stability, simple in structure, scalable, adjustable vernier levelling pole easy to use.
The utility model comprises frame level, vernier class chi, adjustable support bar and is connected and fixed part, it is characterized in that: at the side of the frame level adjustable support bar of bolt, vernier class chi inserts mounting hole on the adjustable support bar by the bolt on the Fastener, uses fixed by nut.
For compact conformation, firm, described frame level side has V-type or U type or semi-circular groove.
The beneficial effects of the utility model are:
1, precision height, versatility is good.As reading chi of the present utility model, make the reading scale division value bring up to 0.02mm vernier class chi (as vernier caliper, vernier depth gauge etc.), satisfied the accuracy of detection requirement of all big-and-middle-sized equipment by 0.5mm.
2, good stability.Adopt frame level as base of the present utility model, contact area is big, and is stable, must the people not hand steered, both can guarantee fully to contact with measured piece, and true reflection detects data, has avoided personal error again.
3, simple in structure, compact, scalable, easy to use.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is Figure 1A portion amplification plan view.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, at the side of the frame level 1 adjustable support bar 2 of bolt, adjustable support bar 2 the bests are hollow tubular such as steel pipe or copper pipe or stainless-steel tube, the mode of being connected and fixed adopts and adds two bolts of weldering in frame level 1 side and pass adjustable support bar 2 bottom corresponding aperture fixed by nut, but in order to make the utility model compactness, firm, offer V-type (seeing that A amplifies to the part) or U type or semi-circular groove in the side of frame level 1, in the groove internal tapping, internal thread is set, adjustable support bar 2 is bumped into uses bolt in the groove.
Be drilled with the mounting hole of equal five equilibrium on adjustable support bar 2, purpose is the placement location of coarse adjustment vernier class chi 3 easily, thereby guarantees that vernier class chi 3 has enough measurement ranges in the actual measurement process.Fastener 4 is used for locking vernier class chi 3, directly adopts movable part back on the vernier caliper to add the weldering bolt and is made, and the bolt on the Fastener 4 is inserted mounting hole on adjustable and the support bar 2, uses fixed by nut, can use.
When using the utility model, earlier with after the spirit-leveling instrument leveling, again adjustable vernier levelling pole is positioned on the measured piece base, by adjusting the secondary vernier in the vernier class chi, " 0 " line in the secondary vernier is overlapped with " one " line in spirit-leveling instrument telescope " ten " word line, tighten the lock screw in the secondary vernier then, at this moment, the numerical value of this measurement point just can directly be read from vernier class chi.
Claims (4)
1. adjustable vernier levelling pole, comprise frame level, vernier class chi, adjustable support bar and be connected and fixed part, it is characterized in that: at the side of the frame level adjustable support bar of bolt, vernier class chi inserts mounting hole on the adjustable support bar by the bolt on the Fastener, uses fixed by nut.
2. adjustable vernier levelling pole according to claim 1 is characterized in that frame level meter side has V-type or U type or semi-circular groove.
