Abstract

The utility model relates to a bevel gear external diameter caliper which is a measuring tool used for measuring the bevel gear external diameter of the chamfer or non chamfer. The utility model has the structure that the left end of a straight ruler is provided with a standard ruler frame, the position of which can be adjusted; the right side of the straight ruler is provided with a number reading ruler frame which can move; the two ruler frames are both provided with fine-motion devices, and the lower part of each fine-motion device is fixed with a V-shaped measuring head. The accessory is a checking ruler and measuring gauge and is the size standard used for setting and checking the position of the standard ruler frame. When a couple of V-shaped measuring heads are tangential respectively with the face cone and back cone of the gear blank at the position of the external diameter, the external diameter value can be read out from the number reading ruler frame. The utility model has the advantages of strong versatility, convenient use, high precision, direct number reading, etc., and can organize socialized and commercialized production.

Description

Bevel gear external diameter caliper and corrective gauge thereof

The utility model bevel gear external diameter slide calliper rule belong to the physical quantity length measuring instrument.Be mainly used in the measurement of chamfering bevel gear external diameter, also can measure the not external diameter of chamfering bevel gear.Its annex " school dipstick metering rule " is the size datum of fixed position that is used for determining and proofreads the station meter frame of these slide calliper rule.

China Machine Press's version in 1992 " write among the mechanical processing technique handbook P20-240: " and the measurement of bevel gear external diameter limit deviation, if the tooth base does not remove wedge angle, available omnipotent measurer (slide calliper rule, milscale) or limitgage are measured; If removed wedge angle, the available dedicated calliper is measured." as seen the bevel gear external diameter of chamfering can not have been measured with general measurer.And general bevel gear is all to need chamfering, and when tooth base car became, chamfering process was finished.So before the intermediate survey of tooth base, cutting to the examination before the check of wheel blank size, bevel gear product inspection warehouse-in, user and the assembling, the mapping when accessory duplicates ... or the like work run into all is the bevel gear of chamfering.And because technical and economically, it is impossible that above-mentioned operation and department all will have special-purpose calliper.Especially when short run, all the more so.

Purpose of design of the present utility model just is: can measure the general measurer of chamfering bevel gear external diameter for departments such as the manufacturing of bevel gear, use, maintenance, mapping provide a kind of.

The purpose of this utility model is achieved in that two mutually chi frames of symmetry is housed on a ruler, its left side is the station meter frame, its right side be reading chi frame." floating type V-arrangement gauge head " is housed respectively on chi frame lower flange.Be somebody's turn to do parts among the patent ZL92231389X " tip distance slide calliper rule " that " gauge head " is me, it can accurately determine the position of bevel gear crown.Now use " the floating type V-arrangement gauge head " of two symmetries to place the two ends of crown garden diameter, again by vernier on the chi frame and the scale value on the ruler, directly read the size reading of this garden diameter, this numerical value promptly is footpath outside the bevel gear.Determining of these slide calliper rule station meter frame position is to adopt " the school dipstick metering rule " of a special use to set up and proofread as size datum.

The utlity model has following advantage:

1, highly versatile.Slide calliper rule can be used to measure the different size in the range ability, the various chamferings at cone bearings of various cone top angle or the bevel gear external diameter of chamfering not.

2, measuring accuracy height.Because: (1) " floating type V-arrangement gauge head " can accurately be determined the crown position, and the external diameter of surveying meets definition; (2) but measurer foozle and wear error are convenient to eliminate in station meter frame adjustable positions school.

3, digital direct-reading.

4, easy to use.

5, be convenient to organizational standardization, seriation, socialization, commercialization production.Can organize specialized production and supply market user directly to choose by measurer factory, exempt the tired brain that designs and make special-purpose gauge to market.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the front elevation of " bevel gear external diameter slide calliper rule ", has expressed the relation between each building block and the state in when work.Two symmetrical chi frames that have vernier are housed on the ruler of a square-section (1) among the figure, one of its left end is adjustable positions, set up fastening station meter frame (2) during use in advance, one of its right side is can go up at an arbitrary position to move and fastening reading chi frame (3).The bottom that " floating type V-type gauge head " (6) and (7) of two symmetries are contained in station meter frame and reading chi frame respectively has on the flange of fixed orifice, adopts releasable connection, so that change gauge head, changes and enlarge the usable range of slide calliper rule.Used " the floating type V-type gauge head " of these slide calliper rule by ZL92231389X " tip distance slide calliper rule " " floating type V-type gauge head " and " bow type main scale Xiao seat " two partly combine.Station meter frame and reading chi frame have inching gear (4) and (5) respectively.

Fig. 2 is the indispensable accessory of these slide calliper rule---" school dipstick metering rule ".It is in order to set up and to proofread the size datum of the restraint location of station meter frame.Its structure is: the middle part is a Cylinder, and two ends are the cone coaxial with Cylinder.The scope of its cone apex angle α is 85 °＜α＜90 °.The gauge both sides respectively process an axial plane, and they are not less than 1/2 of Cylinder radius to the distance of axial line.The distance that " school dipstick metering rule " two ends are top must be measured through accurate, and its measured value is indicated in significantly on the axial plane of school dipstick metering rule.After the pinnacle distance values of surveying and being indicated confirming was errorless, the pinnacle allowed abate.

Provide part name table of the present utility model below:

1, ruler;

2, station meter frame;

3, reading chi frame;

4,5, inching gear;

6,7, floating type V-type gauge head.
