Abstract

The invention relates to a multi-functional caliper which comprises a main graduated ruler with a fixed measuring claw and a sliding measuring claw, an auxiliary graduated ruler arranged vertically on the main graduated ruler and sliding thereon in the axial direction, an auxiliary sliding measuring claw arranged on an auxiliary vernier of the auxiliary graduated ruler relative to the fixed measuring claw on the main graduated ruler, and a chord height-measuring claw axially arranged on the auxiliary graduated ruler. The caliper is used to measure the chord height of a minor arc and also to measure the depth of a work piece. The caliper has multiple measuring functions with less increase in fabrication cost.

Description

A kind of multifuctional calliper
Affiliated field:
The present invention relates to a kind of internal diameter or external diameter that is used to measure objects such as right cylinder and/or pipe, and the multifuctional calliper of action.
Background technology:
Vernier caliper is the measurer that is used to measure the interior external diameter of machine parts or workpiece or thickness etc., is to have the long chi of scale and be installed in the fixation measuring pawl of this long chi one end by one, and is arranged on the slip measuring claw formation on the vernier.With this kind gage measuring machine parts or workpiece the time, its maximum range depends on the length of slide calliper rule, and only limits to measure the interior external diameter or the thickness of machine parts or workpiece, and not the energy measurement minor arc the diameter of corresponding object.
The technology that a kind of name is called " slide calliper rule " is disclosed for No. 155478 at the problems referred to above Chinese patent.These slide calliper rule comprise a fixed proportion chi or rule and slide block, and electronic component, and rule comprises the internal cavities of a longitudinal extension; Measuring sensor comprises that one is extended and two ends are fixed on lead on the rule in cavity; The part that slide block is positioned at rule comprises a permanent magnet; Each end of lead and piezoelectric crystal acting in conjunction lead is connected electrically on the pulse producer, produce the electric pulse of the weak point of predetermined period, pick-up unit in the slide calliper rule and piezoelectric crystal acting in conjunction, measure with this tree diameters that will be clipped between rule pillar and the slider post, though this slide calliper rule energy measurement is than major diameter trees external diameter, but the parts of these slide calliper rule are more, and measuring process is more loaded down with trivial details, and the internal diameter of energy measurement larger object not.
In addition, to be called " slide calliper rule that can be used for radius measurement " also be the solution that proposes at measurement range to a kind of name of No. 2509555, Chinese patent bulletin.These slide calliper rule are three sounding rods to be set having on the common slide calliper rule of main scale and secondary chi, wherein decide bar and be contained on the main scale for two, another moving bar is contained on the secondary chi and moves relative to deciding bar with secondary chi, decide bar and contact with measured circular arc simultaneously for two during measurement with a moving bar, by identical with the electronic type quantity slide calliper rule again electronic circuit one capacitance type sensor logotype of three contact point coordinates, calculate the pairing radius of this arc, these slide calliper rule finally can be measured the testee radius corresponding by minor arc, but these slide calliper rule must combine with its corresponding electron device, its process of measurement is comparatively loaded down with trivial details, and cost of manufacture is higher.
Summary of the invention:
The purpose of this invention is to provide a kind of interior external diameter or thickness that is used to measure part or workpiece, and the multifuctional calliper of the chord length and the degree of depth.
Multifuctional calliper proposed by the invention comprises the master calibration chi, and an end of this master calibration chi is provided with the opposite fixation measuring pawl of both direction and a slip measuring claw that limits by main cursor; Vertically being installed in also can be along its secondary in axial sliding rule on the master calibration chi, the secondary vernier of secondary rule be provided with the master calibration chi on the corresponding secondary slip measuring claw of a fixation measuring pawl, and be axially installed with the action measuring claw at secondary rule.
Being provided with in one end of described master calibration chi can be along its axially movable depth survey pawl.
Described secondary vernier comprises and can and be installed in upright guide groove on the sliding sleeve along the axially movable sliding sleeve of master calibration chi, and is used for sliding sleeve is fixed on fastening bolt on the secondary rule.
Multifuctional calliper proposed by the invention adopts a secondary rule that is installed on the master calibration chi, and the action measuring claw is installed on secondary rule, can be used to measure the action of minor arc, can extrapolate the radius or the diameter of testee by the action value, simultaneously, in the master calibration chi, also be provided with the depth survey pawl, the degree of depth that can measuring workpieces, so this kind slide calliper rule have multiple measurement function, and can't increase how many costs of manufacture.
Description of drawings:
Accompanying drawing 1 is the surface structure synoptic diagram of an embodiment of multifuctional calliper proposed by the invention.
Embodiment:
Referring to Fig. 1, this figure provides the overall appearance structure of an embodiment of multifuctional calliper proposed by the invention.This kind slide calliper rule comprise master calibration chi 1 and secondary rule 2, and depth survey pawl 3.
One end of master calibration chi 1 is provided with the opposite and fixation measuring pawl 11 and 12 in same plane of both direction, being equipped with one on master calibration chi 1 can be along its axially movable main cursor 13, and be equipped with on main cursor 13 and fixation measuring pawl 11 corresponding slip measuring claws 14, fixation measuring pawl 11 and slip measuring claw 14 are used to measure the diameter of part or workpiece.Master calibration chi 1 is away from a side hollow of fixation measuring pawl 11, and depth survey pawl 3 can extend in the hollow part of master calibration chi 1 and can move axially along it, in order to the degree of depth of measuring workpieces.
Secondary rule 2 comprises secondary vernier 21 chord high measurement pawls 22.Secondary vernier 21 has and can and be installed in upright guide groove 24 on the sliding sleeve 23 along the axially movable sliding sleeve 23 of master calibration chi 1, and is used for sliding sleeve 23 is fixed on fastening bolt 25 on the secondary rule 2; Secondary rule 2 vertically is installed on the master calibration chi 1 and by secondary vernier 21 and can endwisely slips along it, secondary vernier 21 be provided with master calibration chi 1 on a fixation measuring pawl 12 corresponding secondary slip measuring claws 26, fixation measuring pawl 12 and slip measuring claw 26 are used to measure part or inner diameter of workpiece.When measuring the special minor arc of circular arc, at first with fixation measuring pawl 12 and slip measuring claw 26 or measure the chord length of minor arc with fixation measuring pawl 11 and slip measuring claw 14, and then measure the action of this minor arc with action measuring claw 22, theorem according to " in the plane not three of conllinear can determine a circle " calculates this minor arc place diameter of a circle easily.
