Abstract
The utility model discloses a micrometer for measuring a ball span of an external gear and an external spline, which comprises a micrometer, two measuring heads and a clamping spring ring. Each measuring heads comprises a spherical measuring head, an intermediate transitional shaft and a pin shaft, pin shaft sections are inserted in small holes of measuring anvils at the two ends of the micrometer, and the measuring ends of the measuring heads respectively adopt a sphere with a standard diameter phi of 2-50mm. The measuring heads are used in pairs, the spherical measuring heads have the same diameter and the same tolerance zone, and the distances from the centers of the spherical measuring heads to the end faces of the measuring anvils are identical. When the measuring heads are arranged in place, zero debugging is carried out and then the micrometer can be directly used for measuring the ball span. The micrometer fully utilizes a precision length measurement mechanism of the commodity micrometer for measurement. Moreover, the micrometer has a simple combined structure, is easy to operate for measurement, achieves accurate measurement, and is particularly suitable for use as an online testing tool for production posts.
Description
Technical field
The utility model relates to a kind of length measuring device, and specifically, the utility model relates to the milscale of a kind of accurate measurement involute urve outer rotor, involute outer spline, triangle male splines sphere distance.
Background technology
Involute urve outer rotor, involute outer spline and triangle male splines all belong to a class external tooth part in the mechanical component, and a common important structure size---actual transverse tooth thickness is arranged in its structure.The precision measuringtoll that does not have directly to measure actual transverse tooth thickness in the existing measurer has only the common normal of employing or sphere distance to measure and reflects actual transverse tooth thickness value indirectly.The common normal measurement is known mature technology, and the commodity milscale of measuring common normal is arranged on the market, can accurately measure the length of common normal.But still there is limitation in actual use in existing common normal micrometer.For example, when the big or facewidth of the helix angle of measured workpiece was narrower, common normal micrometer just can't be measured.It also is ripe measuring technique in the gear manufacturing industry that sphere distance is measured, and the testing tool that this technology is used adds the steel ball or the length bar of two equal diameters as outside micrometer, and this kind measuring technique measurement result accurately, reliably., existing sphere distance measuring appliance is scattered structure, and the multiple measurement operation not only bothers but also operating personnel are measured technical ability certain requirement.Otherwise, the accuracy affected of measurement result, and efficiency of measurement is very poor.Existing sphere distance measuring technique only is fit to the professional to be measured, and is not suitable for shop floor worker self check usefulness aborning.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, proposes a kind of measurement outer rotor of unitized construction and the sphere distance milscale of male splines, this is simple in structure, combination is easy, easy and simple to handle, measure accurately.
The utility model is achieved through the following technical solutions technical goal.
Measure the sphere distance milscale of outer rotor and male splines, it is made of jointly milscale, gauge head and jump ring circle.Its improvements are: described gauge head is made up of spherical measuring head, middle transition axle and bearing pin, the bearing pin section is inserted the interior formation of the aperture follower structure of milscale two ends gage button, the spherical measuring head of gauge head is the spheroid of Φ 2mm～Φ 50mm, the bearing pin section that cooperates with gage button is a right cylinder, and the right cylinder stage casing is provided with the spill annular groove jump ring is installed.
In the said structure, according to the modulus of measured workpiece, select the gauge head of corresponding size to be inserted in the gage button of milscale two ends, its spherical measuring head diameter of gauge head that pairing is used and tolerance range equate that the centre of sphere of spherical measuring head to gage button end face distance equates.
The utility model compared with prior art has following good effect:
1, gauge head and gage button unitized construction are simple, installation is easy, low cost of manufacture;
2, gauge head moves with gage button, and measuring operation is convenient, and is low to operating personnel's measurement technical ability requirement, is fit to do online quality testing apparatus;
3, disposable detection in place, detection is accurate, efficient is high.
Description of drawings
Accompanying drawing 1 is that the utility model structure master looks synoptic diagram.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings below.
Measure the sphere distance milscale of outer rotor and male splines shown in the accompanying drawing, it is made of jointly milscale 1, gauge head 2 and jump ring circle 3.Described gauge head 2 is made up of spherical measuring head, middle transition axle and bearing pin, the bearing pin section is inserted in the aperture of milscale 1 two ends gage button 1.1, spherical measuring head directly contacts measured workpiece, its spherical measuring head is the spheroid of Φ 2mm～Φ 50mm, the bearing pin section that cooperates with gage button 1.1 is a right cylinder, and the right cylinder stage casing is provided with the spill annular groove jump ring 3 is installed.Gauge head 2 pairings are used in the utility model, and the spherical measuring head diameter of two gauge heads and tolerance range equate that the centre of sphere of spherical measuring head to gage button 1.1 end face distances equate.A pair of gauge head 2 axially inserts in the milscale 1 two ends gage button 1.1 respectively, and the related equipped gauge head 2 of gage button moves and measures during turn milscale 1.Before installing, gauge head 2 selects the gauge head 2 of suitable diameter earlier according to the modulus of workpiece.The present embodiment modulus is 3.5mm, selects for use the gauge head 2 of Φ 6mm to be installed on the gage button.Select the principle of gauge head 2 to contact to suitable with workpiece flank middle part with gauge head 2 middle parts.After gauge head 2 is in place, do the school zero adjustment earlier, directly measure then, more measured sphere distance is converted into corresponding actual transverse tooth thickness value with sphere distance.
The length delicate metering mechanism that the utility model makes full use of the commodity milscale measures, and its unitized construction is simple, and measuring operation is convenient, measure accurately, is particularly suitable for doing the online detection apparatus on the production station.
