Abstract
The utility model provides a complex caliber rule for measuring bore diameter and bore distance, which is a measuring tool which integrates a gauge used for a circular hole and a vernier caliper into a whole and improves respective structure. When the utility model is used for measuring for one time, the purpose of testing whether the bore diameter satisfies the requirement of the prescribed deviation or not and the purpose that the bore distance is precisely measured are achieved. The measuring caliber rule is composed of a main rule, a vernier, two measuring head tools assembled by stopping ends, clamping ends and passing ends, a fixing bolt and a pushing and pulling head. The measuring caliber rule has the advantages of simple operation, convenient use, high work efficiency and high precision of the measured bore distance, and the complex caliber rule for measuring bore diameter and bore distance is suitable for testing the bore diameter and measuring the bore distance.
Description
The utility model relates to a kind of aperture and pitch of holes survey instrument, particularly combines the gauge that the check circular hole uses and the survey instrument of vernier caliper, and improved structure separately, it is to check the whether slide calliper rule of qualified and accurate measured hole spacing of aperture that circular hole has a predetermined tolerance requirement simultaneously.
When existing circular hole is tested in the aperture that circular hole is had the regulation deviation require with gauge, although have the measuring head tool of the control upper deviation and lower deviation dimension limit---be cylindrical plag, to judge that this aperture is whether in the margin tolerance of stipulating.But can not determine the home position in this aperture, the home position in this hole also just can not be provided for the pitch of holes of measuring this hole and other circular holes.Centre distance between measured hole and the hole, promptly pitch of holes also needs to adopt in addition survey instrument---vernier caliper.
Its organigram of existing vernier caliper is with reference to Fig. 1, and it is linked as a whole internal diameter dop (1) and an external diameter dop (8), vernier scale (4) and is linked as whole an internal diameter dop (2) and an external diameter dop (7), set bolt (3), push-and-pull head (6) with vernier scale by main scale (5) and with main scale is formed.When pitch of holes being measured with vernier caliper, vernier caliper uses earlier a pair of internal diameter dop (1,2) to measure two circular holes at the maximum tangent distance between circumference each other respectively, use a pair of external diameter dop (7,8) to measure the minimum tangent distance of two circular holes on circumference each other again, perhaps order of operation is opposite.Resulting maximum tangent distance value and the addition of minimum tangent distance value, again divided by 2, institute's value is pitch of holes then.Like this, the numerical value of pitch of holes is measured and is once calculated and obtain through secondary, thereby time-consuming bothersome.In addition, be the edge of a knife because two couple of vernier caliper measures dop with certain width, thereby in the pitch of holes of measuring circular hole, during especially than the pitch of holes of small sircle hole, measuring dop is not that a line contacts with hole wall, but the two-lines contact, so influence measuring accuracy.Moreover whether the check aperture satisfies the tolerance of regulation and the numerical value of measured hole spacing divided for two steps finished, and therefore, certainly will reduce work efficiency.
The purpose of this utility model is that a kind of collection circular hole will be provided is one with gauge and vernier caliper, and has improved the measurement slide calliper rule of gauge and vernier caliper structure.It can disposablely easily reach tolerance and accurate these two purposes of measured hole spacing whether the check aperture satisfies regulation, thereby has improved work efficiency.
The utility model is finished as follows: measure slide calliper rule and comprise the main scale that indicates scale, indicate scale and be enclosed within vernier scale and two measuring head tools that can slide arbitrarily on the slide rail of main scale.
Measuring head tool of the present utility model is formed by three sections.Epimere is the not-go-end of columniform circular hole with gauge, and hypomere is the go side of columniform circular hole with gauge, and the stage casing is the card end of truncated cone-shaped, the same size with the go side diameter of its minimum diameter, the same size with the not-go-end diameter of its maximum gauge.
Measuring head tool of the present utility model be by three sections straight lines along longitudinal axis Rotate 180 ° two right cylinders and a Rotary-table of being constituted, and they are concentric.
Advantage of the present utility model is simple to operate, easy to use.When tested two circular holes have passed through two go sides of measuring head tool respectively, think that then these two circular holes have satisfied the lower deviation requirement of regulation.When tested two circular holes two not-go-end by the measuring head tool not all, think that then these two circular holes have satisfied the upper deviation requirement of regulation.This just can confirm the tolerance that this circular hole is up to specification.At this moment, the card end must snap in the tested circular hole respectively; Thereby can be used by the scale mark that is labeled in respectively on main scale and the vernier scale, obtain the accurate numerical value of pitch of holes.Can check the aperture whether to satisfy size tolerance requirements and mensuration pitch of holes so simultaneously, and the pitch of holes precision height that records, the workload of detection is little, high efficiency.
Below with reference to accompanying drawing utility model is described in further detail:
Fig. 1 is the structural representation of vernier caliper.
Fig. 2 is a structural representation of the present utility model.
With reference to Fig. 2, mark and be with mark graduated vernier scale (2) on the slide rail of graduated main scale (1), in the vernier scale upper end set bolt (3) is arranged, at vernier scale lower end afterbody a push-and-pull head (4) is arranged, two measuring head tools are made up of not-go-end (5), card end (6), go side (7) respectively.
During operation, hold main scale (1) with the right hand, thumb makes it to go up slip at main scale (1) firmly in push-and-pull head (4), regulates the distance of two measuring head tools, makes their go side (7) aim at two tested circular holes just.Whether passed through the lower deviation requirement that circular hole judges that this two circular hole is whether up to specification according to go side (7) then.If the go side has been passed through circular hole and has been clamped in card and holds in (6), both can be used scale on the main scale (1) and the scale on the vernier scale (2), directly read the accurate numerical value of two circular hole pitchs of holes.Also available set bolt this moment (3) is fixed in vernier scale (2) on the main scale (1), after slide calliper rule to be measured take out from circular hole, carries out reading again.If all not by not-go-end (5), then this two circular hole of decidable satisfies the upper deviation requirement of regulation to these two tested circular holes.This shows that the aperture is qualified in the margin tolerance of regulation.
