Abstract
The invention provides a vernier caliper and micrometer combined measuring instrument comprising a main ruler. The front end of the main ruler is provided with a lengthened and thickened fixed measuring claw. The main ruler is sleeved by a vernier. A lengthened flexible measuring claw is arranged below the vernier. A micrometer is fixedly connected below the flexible measuring claw. The front end of the micrometer is provided with a flat measuring head. A stop block used for limiting the stroke of the vernier is arranged on the 0 scale of the main ruler. Distance between the 0 scale of the main ruler and the fixed measuring claw is equal to measuring range of the micrometer. Advantages of the vernier caliper and the micrometer are drawn so that measuring scope is wide, measuring precision is high, and the vernier caliper and micrometer combined measuring instrument is convenient and rapid.
Description
Technical field
The present invention relates to a kind of survey instrument, specifically a kind of vernier caliper milscale multiple measurement utensil.
Background technology
When the object using the miking diameter of axle larger, because the range of milscale is limited, just more difficult when the measurement thing larger to the diameter of axle is measured, simultaneously, if use vernier caliper to measure large-diameter measurement thing, the measuring accuracy of vernier caliper is lower, does not reach the requirement of accurately measuring, for this reason, in conjunction with milscale and vernier caliper advantage, design a kind of utensil, when the measurement thing larger to the diameter of axle is measured, the measured value that precision is higher can be reached.
Summary of the invention
Problem to be solved by this invention is the deficiency overcoming above-mentioned prior art, provides a kind of structure simple, measures vernier caliper milscale multiple measurement utensil accurately.
The present invention realizes as follows: a kind of vernier caliper milscale multiple measurement utensil, comprise main scale, the front end of described main scale is provided with the fixing measuring jaw lengthening and thicken, on described main scale, cover has vernier, the below of described vernier is provided with the movable measuring jaw of lengthening, the below of described movable measuring jaw is fixedly connected with milscale, described milscale is provided with flat measuring head near the side of fixing measuring jaw, the end face of described measuring head is parallel with the end face of fixing measuring jaw, the end face of described measuring head and the axes normal of main scale; 0 scale of described main scale is provided with the block for limiting vernier stroke, and the distance between 0 scale of described main scale and fixing measuring jaw equals the range of milscale.
It is further: described measuring head is conical measuring head, and the large end of described measuring head is positioned near fixing measuring jaw side.
The range of described milscale is 10mm.
Described main scale is provided with fine setting in the rear end of vernier.
Described vernier is provided with trip bolt.
The length of described fixing measuring jaw is not less than the distance of lower end to main scale of milscale.
The present invention has the following advantages: the present invention with the addition of milscale on the basis of original vernier caliper, and by the adjustment large number of vernier caliper main scale and integer during measurement, and go out decimal by miking, the two sum is exactly the numerical value of measurement size.By lengthening vernier caliper two measuring claw, adjustment vernier caliper main scale size, all can measure any size axis size and outside dimension.This measuring appliance draws the advantage of vernier caliper, both milscales, and measurement range is wide, and measuring accuracy is high, can reach 0.01, and convenient, fast.

Fig. 1 is structural representation of the present invention;
In figure: 1, main scale, 2, fixing measuring jaw, 3, vernier, 4, block, 5, milscale, 6, measuring head, 7, fine setting, 8, trip bolt, 9, movable measuring jaw.
Embodiment
Vernier caliper milscale multiple measurement utensil as shown in Figure 1, comprise main scale 1, the front end of described main scale 1 is provided with the fixing measuring jaw 2 lengthening and thicken, on described main scale 1, cover has vernier 3, the below of described vernier 3 is provided with the movable measuring jaw 9 of lengthening, the below of described movable measuring jaw 9 is fixedly connected with milscale 5, described milscale 5 is provided with flat measuring head 6 near the side of fixing measuring jaw 2, the end face of described measuring head 6 is parallel with the end face of fixing measuring jaw 2, the end face of described measuring head 6 and the axes normal of main scale 1; 0 scale of described main scale 1 is provided with the block 4 for limiting vernier 3 stroke, and the distance between 0 scale of described main scale 1 and fixing measuring jaw 2 equals the range of milscale 5.The range of described milscale 5 is 10mm.The present invention is a kind of vernier caliper milscale multiple measurement utensil, mainly include a main scale, and be fixed with fixing measuring jaw in the front end of main scale, for convenience of measuring large-diameter measurement thing, therefore fixing measuring jaw is herein lengthen the fixing measuring jaw thickeied, and increases the contact area measured; Main scale is also provided with vernier, the below of vernier is fixed with the movable measuring jaw of lengthening, the lower end of movable measuring jaw is fixedly connected with milscale, milscale is provided with measuring head near one end of fixing measuring jaw, also for ease of the contact area increasing and measure, measuring head is flat measuring head herein, simultaneously, the end face of the measuring head of milscale is parallel with the end face of fixing measuring jaw, and with the axes normal of main scale; And use the movable measuring jaw lengthened, be convenient to when measuring large-diameter measurement thing, the measuring head of milscale can touch the maximum outside diameter place measuring thing; When measuring with device of the present invention, the conveniently school zero of vernier, 0 scale of main scale is provided with the block for limiting vernier, distance simultaneously between 0 scale and fixing measuring jaw is the range of milscale, like this when measuring end and carrying out reading, the reading of milscale is added with the reading of vernier, just can obtains desired measurement result.During concrete measurement, vernier slide carries out school zero to the position of block, and simultaneously the measuring head of milscale and fixing measuring jaw Contact milscale carry out school zero; Measurement thing is placed between fixing measuring jaw and measuring head by next step, and fully contact, the adjustment position of vernier on main scale, the pointer of vernier is made to refer on the integer scale of main scale, then the fractional value by regulating miking to obtain measurement size, is added the accurate measurements reaching the diameter of axle by two parts numerical value.This structure is simple, and measurement result is accurate, improves the degree of accuracy of measured value.
Vernier caliper milscale multiple measurement utensil as shown in Figure 1, described measuring head 6 is conical measuring head, and the large end of described measuring head 6 is positioned near fixing measuring jaw 2 side.The shape of the measuring head of milscale used in the present invention is conical, increases measuring head and the contact area measuring thing, improve the accuracy of measuring when being convenient to measure.
