Abstract
Bearing ditch heart is apart from measuring master tool based on slide caliper, main scale (6) one end of slide caliper has constant amount claw (2), and slide kit vernier (5) are gone up in slide caliper main scale (6), install slip masuring jaw (3) on vernier (5), install the same ditch bulbus cordis piece (1) respectively at the lower extreme of constant amount claw (2) and slip masuring jaw (3), and wherein, ditch bulbus cordis piece (1) bottom is the sphere. On slide caliper's infrastructure basis, carry out the transformation of adaptability to convenient accurate measurement, the appearance volume is less, light in weight, practice thrift the cost, measurement accuracy is good efficient, can measure the raceway ditch heart distance of different specifications, if change preceding master ball piece just can, measuring range is wide, the measurement convenience.
Description
Technical field
The utility model relates to the technology of the measurement of field of machining centre bearer ditch heart distance, belongs to a kind of bearing groove heart distance and the depth of parallelism holds surveying instrument, especially based on the bearing groove heart of vernier caliper apart from sample plate instrument.
Background technology
In prior art, axle ditch heart distance and the depth of parallelism hold measurement three-coordinate instrument, measure cost higher, measure major diameter circle inconvenient, at bearing industry, large-scale pair of ditch bearing groove heart distance and two ditch depth of parallelism are measured, there is no desirable cubing, when detecting apart from model with the common ditch heart, because large style ferrules is not easily moved, measuring inconvenient key is that measuring accuracy is low; Also be difficult to judge that whether the ditch heart apart from qualified, has a strong impact on the trap rate of bearing finished products with light gap method, production efficiency and product quality lower.
On the other hand, at the vernier caliper that machine work field is generally applied, it is a kind of measurer measuring length, internal-and external diameter, the degree of depth.Vernier caliper is by main scale and be attached to slidable vernier two parts on main scale and form.Main scale is generally in units of millimeter, vernier then there are 10,20 or 50 lattices, according to the difference of lattice, vernier caliper can be divided into extremely spends vernier caliper, 20 points of degree vernier calipers, 50 points of degree lattice vernier calipers etc., vernier be 10 calibration have 9mm, 20 calibration have 19mm, 50 calibration have 49mm.The main scale of vernier caliper and vernier have two secondary movable measuring jaws, are internal measure-hand and external pelivimetry pawl respectively, and internal measure-hand is commonly used to measure internal diameter, and external pelivimetry pawl is commonly used to measure length and external diameter.
According to the difference of lattice, vernier caliper can be divided into extremely spends vernier caliper, 20 points of degree vernier calipers, 50 points of degree lattice vernier calipers etc.The main scale of vernier caliper and vernier have two secondary movable measuring jaws, are internal measure-hand and external pelivimetry pawl respectively, and internal measure-hand is commonly used to measure internal diameter, and external pelivimetry pawl is commonly used to measure length and external diameter.Pit gauge and vernier scale connect together, and can survey the degree of depth of groove and cylinder.
Hold among measurement in bearing groove heart distance and the depth of parallelism, also not having can as vernier caliper, easy to use, measure precisely, and be simple and easy to instrument.
Utility model content
The purpose of this utility model is to provide the bearing groove heart distance sample plate instrument based on vernier caliper, to solve the Measurement accuracy problem of large-scale bearing ring ditch heart distance and the depth of parallelism.
The purpose of this utility model will be realized by following technical measures: comprise ditch bulbus cordis sheet, fixing measuring jaw, slip measuring jaw, vernier and main scale; There is fixing measuring jaw main scale one end of vernier caliper, and the main scale of vernier caliper slides suit vernier, and vernier being installed slip measuring jaw, install identical ditch bulbus cordis sheet respectively in the lower end of fixing measuring jaw and slip measuring jaw, wherein, is sphere bottom ditch bulbus cordis sheet.
Especially, register pin installed by vernier.
Especially, ditch bulbus cordis sheet is that semicircle is spherical.
Especially, ditch bulbus cordis sheet top is connected to the lower end of fixing measuring jaw and slip measuring jaw by connecting link spiral.
Especially, ditch bulbus cordis sheet external diameter is identical with raceway trench cross section diameter to be measured.
Advantage of the present utility model and effect: on the basic structure basis of vernier caliper, carry out adaptive transformation, measure accurately to facilitate, overall volume is less, lightweight; Cost-saving, good measuring accuracy efficiency is high, can measure the raceway ditch heart distance of different size, as long as it is just passable to change standard ball sheet above, measurement range is wide, and it is convenient to measure.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 structural representation.
Reference numeral comprises: ditch bulbus cordis sheet 1, fixing measuring jaw 2, slip measuring jaw 3, register pin 4, vernier 5, main scale 6.
Embodiment
The utility model principle is, principle standard steel ball is cut into hemisphere sheet by bolt the measurement carrying out ditch heart distance on vernier caliper after calibration.
The utility model comprises: ditch bulbus cordis sheet 1, fixing measuring jaw 2, slip measuring jaw 3, vernier 5 and main scale 6.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, there is fixing measuring jaw 2 main scale 6 one end of vernier caliper, the main scale 6 of vernier caliper slides suit vernier 5, vernier 5 is installed slip measuring jaw 3, in the lower end of fixing measuring jaw 2 and slip measuring jaw 3, identical ditch bulbus cordis sheet 1 is installed respectively, wherein, bottom ditch bulbus cordis sheet 1 be sphere.
In aforementioned, vernier 5 is installed register pin 4.
In aforementioned, ditch bulbus cordis sheet 1 is that semicircle is spherical.
In aforementioned, ditch bulbus cordis sheet 1 top is connected to the lower end of fixing measuring jaw 2 and slip measuring jaw 3 by connecting link spiral.Namely ditch bulbus cordis sheet 1 can be changed.
In the present embodiment, ditch bulbus cordis sheet 1 external diameter is identical with raceway trench cross section diameter to be measured.
In the utility model, the most major groove heart apart from the most ditch heart apart from difference be the double channel depth of parallelism.
The utility model is when applying, turn register pin 4, making vernier 5 be in slidably state, the ditch bulbus cordis sheet 1 of the lower end of fixing measuring jaw 2 and slip measuring jaw 3 is inserted respectively the raceway bottom of trench of bearing to be measured, regulating vernier 5 to correct position and reading numerical values to realize the ditch heart apart from measuring; In known ditch heart distance, need to the manufactured raceway ditch heart apart from when detecting whether up to standard, can securing dowel 4, vernier 5 is located.
