Abstract
The utility model discloses a multi-function double-vernier caliber rule. The utility model is characterized in that two verniers (2) are symmetrically distributed on a main scale of the caliber rule, a measuring edge is a replaceable measuring jaw (7) which is arranged below the internal sides of the two verniers (2), a scale mark corresponding to zero position on the left end on the main scale is corresponding to the centerline of a vernier measuring jaw on the left side and can be adjusted, the left side of the scale mark correspomding to zero position on the left end of the main scale is also provided with a scale mark, the minimum range is generated when the right and the left verniers are contacted with each other, the replaceable measuring jaw (7) forms a truncated cone shape, the taper varies with the geometric shape of a measured part, one caliber rule can be used for replacing a corresponding measuring jaw to satisfy the measurement of various units under test, especially sealing grooves or sealing rings with various specifications on the petroleum machinery products. The utility model has the advantages of convenient use, visual reading, high durability, economical manufacture and convenient management and maintenance.
Description
The utility model discloses a kind of multi-functional double vernier slide calliper rule, belongs to a kind of measurement measurer in the physics.
Being used for the measurer in Measuring Object length or circle footpath in the commercial production often is common calliper, but in oil and chemical machinery product, seal groove and sealing steel loop that all size is arranged, common vernier caliper can't be measured, though seal groove or sealing steel loop specification are a lot, exist general character in shape.At present, producing this part both at home and abroad all is to adopt special for this reason special-purpose clamp measurement size, the seal groove of each specification is measured just needs the special-purpose clamp of second mate, therefore there is the seal groove of tens kinds of specifications to need tens secondary special-purpose clamps, the measuring method of sealing steel loop (wearing tapering) also is same, produce the seal groove or the sealing steel loop part of hundreds of specification, the special-purpose clamp quantity that is used to detect dimensional accuracy is very big, this is not only the manufacturing funds costliness that is used to make special-purpose clamp, and the management difficulty of the use of clamp is very big, it comprises the wearing and tearing maintenance in keeping and the use of depositing in the use, for the user of product, then can't the quality of this product be carried out an acceptance inspection especially.
The purpose of this utility model provides a kind of multi-functional double vernier slide calliper rule, is used for dimensional measurement to the seal groove of petroleum machinery product or sealing steel loop, can satisfy product measurement to tens kinds of specifications to slide calliper rule with one.
For achieving the above object, the utility model is to realize like this, as everyone knows, common vernier caliper all is by main scale, vernier and measurement sword are formed, feature of the present utility model is two verniers (2) that the main scale (1) of slide calliper rule is provided with symmetrical distribution, measure sword and be arranged on the interchangeable measuring claw (7) below the survey in two verniers (2), vernier (2) measuring claw center, left side is corresponding with main scale left end " 0 " position scale, and scalable, left and right sides vernier is a minimum range when contacting, left and right sides vernier has the scale mark that has cooperated the pin-point reading effect with main scale on (2), and zero-bit groove left side also has groove on the main scale, is worth the length greater than vernier (2) its quarter, main scale has multiple range specification, can be provided with the digital lcd display device on two verniers (2), liquid crystal indicator substitutes the groove reading.Its body of described interchangeable measuring claw (7) can be truncated cone or right cylinder, the tapering of cone changes with the geometric configuration of measured piece, the big end at last small end following, has the positioning cylinder that cooperates with vernier (2) high precision on measuring claw (7) upper surface, in vernier, be provided with the lock-screw (8) of vertical direction locking measuring claw on the survey face, described two verniers (2) outside is associated with vernier tuning device (4), connect with fine setting screw rod (6) between vernier tuning device and vernier, the fine setting screw rod is parallel with main scale, infiltrate in the vernier tuning device (4) and mesh with fine-tuning nut (5), side above two verniers (2) is provided with holding screw (3), two vernier tuning device tops are provided with holding screw (9), turn fine-tuning nut (5) like this, vernier (2) can obtain trace and move, then, holding screw (3) and (9), can read the size of measured piece, interchangeable measuring claw (7) changes with the tested part geometric configuration, specification can reach tens kinds even hundreds of, therefore with one the double vernier slide calliper rule are cooperated various interchangeable measuring claws, can finish the measurement of tens kinds of tested parts, in the use, when measuring seal groove internal diameter or outside dimension precision, according to above-mentioned design concept, the operative employee can give the size that deducts earlier or add measuring claw, promptly if with the vernier (2) in left side from the zero-bit groove free size that moves to left or move to right, if measuring claw uses wearing and tearing long afterwards, then Mo Sun free size is also handled with this way, make survey measurements consistent with measured piece pattern nominal size, measurement data is clear and intuitive.Tested part changes once, and measuring claw (7) is changed once, because measuring claw is a rotatable symmetric objects, any straight line on cone surface all might become the measurement sword, so the use of measuring claw wearing and tearing are minimum, and the life-span is very long.
With Figure of description the utility model is further set forth below.
Accompanying drawing is the utility model structural representation.
The label of each element title is respectively among the figure: (1) main scale, and (2) vernier, (3) holding screw, (4) vernier tuning device, (5) fine-tuning nut, (6) fine setting screw rod, (7) interchangeable measuring claw, (8) lock-screw, (9) holding screw,
Embodiment: with reference to the accompanying drawings, main scale (1) range is made as 300mm, minimum range is made as 30mm according to present manufacturing accuracy, interchangeable measuring claw (7) is according to various seal grooves on the measured piece petroleum machinery product or sealing steel loop physical dimension, make the truncated cone of various corresponding taperings, and put on the tapering mark and be convenient to deposit and use, measure the seal groove or the sealing steel loop of tens kinds of specifications like this, just only need multi-functional double vernier slide calliper rule with one, mix the measuring claw of all size, can finish measurement.This slide calliper rule are sometimes referred to as oil and the special-purpose slide calliper rule of chemical machinery, in case of necessity, can be provided with the digital lcd display device on two verniers (2), substitute the groove reading, and the digital lcd display device is a prior art, repeats no more.Seal groove that the utility model energy measurement is the most frequently used and sealing steel loop comprise and measure whole seal grooves of U.S. API standard and sealing steel loop.
The utlity model has easy to use, reading is directly perceived, durable in use, make economical, Be convenient to the advantages such as management and maintenance.
