Abstract

The invention discloses a gear ring inner tooth inter-bar spacing measuring gauge, which consists of an inner support, length bars and a length measure. The length bars are cylindrical bars. The two length bars are respectively put in opposite tooth grooves of the inner hole of a workpiece in a contact way. The inner support is a straight bar with adjustable length. The inner support which is transversely placed in the inner hole of the workpiece is perpendicular to the length bars. The two ends of the inner support straightly press the outer walls of the length bars to form a positioning structure. The length measure is an outside micrometer. The two ends of the outside micrometer are jointly in contact with the positioned length bars during inner tooth inter-bar spacing measurement. The gear ring inner tooth inter-bar spacing measuring gauge has the advantages that since the length bars are rigidly supported by the inner support, the position is stable and the measurement accuracy is high; since the structure is simple, the gauge is easy to install, the detection is facilitated and the gauge is very suitable for detection in a production field; since the gauge is provided in the production field, conditions are provided for timely detection and batch out-of-tolerance quality accidents are prevented from occurring; the gear ring inner tooth inter-bar spacing measuring gauge is suitable for inner tooth inter-bar spacing measurement of gear rings with different specifications.

Description

Gear ring internal tooth interrod spacing is measured cubing
Technical field
The present invention relates to a kind of cubing of measuring for length dimension, specifically, the present invention relates to a kind of cubing that gear ring internal tooth interrod spacing is measured of measuring.
Background technology
Gear ring is the critical piece in automobile differential, and its quality directly affects transmission quality.In batch production process, to inspect at random gear ring crudy by random samples, to avoid and scrap in batches quality accident.Gear ring internal tooth interrod spacing is one of important quality index, belongs to essential items for inspection.Gear ring interrod spacing is measured as position measurement, and conventional length measuring device can not be directly used in measurement, and the industry can both realize accurate measurement with three-coordinates measuring machine or gear measuring apparatus.But these equipments belong to exact instrument, testing conditions requirement is high, the time is long, cost is large, can only detect for pattern, is not suitable for production scene and detects.In order to prevent, in production line, overproof problem in batches occurs, the industry generally adopts two length bars to be placed in respectively relative teeth groove, and a people pins two rods, and another people measures two length bars and draws internal tooth interrod spacing value with vernier scale.The method cubing used is very simple, installation is easy, less demanding to testing conditions, is particularly suitable for detecting in production scene.The problem that prior art exists is to detect operation to need two people to coordinate, and efficiency is poor, and measuring accuracy be affected by human factors larger, so prior art can only be measured for the not high gear ring internal tooth interrod spacing of accuracy requirement.
Summary of the invention
The present invention locates inaccurate problem by two length bars mainly for prior art by artificial hand, and proposing a kind of simple in structure, easy and simple to handle, location reliably, does not need artificial hand by the gear ring internal tooth interrod spacing detection tool of two length bars.This cubing one man operation, detection efficiency is high, and accuracy of detection is high.
The present invention is achieved through the following technical solutions technical goal.
Gear ring internal tooth interrod spacing is measured cubing, and it consists of jointly inner support, length bar and length measurer.Described length bar is cylindrical rod, and by the length bar of tooth module choice criteria diameter in workpiece, two length bars are respectively by being put in the teeth groove that inner hole of workpiece is relative.Its improvements are: the straight rod member that described inner support is adjustable in length, and the inner support and the length bar that are disposed across in inner hole of workpiece are perpendicular, and straight top, two ends length bar outer wall forms positioning expander locking structure; The oriented length bar of the common contact of described length measurer two ends gauge head is made internal tooth interrod spacing and is measured.
In said structure, inner support stage casing is provided with adjustable diameter and screw adjusting structure, and length measurer is outside micrometer.
The present invention compared with prior art, has following good effect:
1, simple in structure, install easily, detect convenient, be adapted at production scene for detection of;
2, length bar is by inner support rigid support, and position stability, measures accurately.
Accompanying drawing explanation
Fig. 1 be the present invention for detection of example structure diagrammatic cross-section.
Fig. 2 is the structural representation that inner support is arranged on gear ring inner support length bar.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the invention will be further described.
Gear ring internal tooth interrod spacing shown in Fig. 1 is measured cubing, and it consists of jointly inner support 1, length bar 2 and length measurer 3.Described length bar 2 is cylindrical rod, by the length bar 2 of the interior tooth module choice criteria of workpiece 4 diameter.The interior tooth module of the present embodiment workpiece 4 to be checked is 5mm, chooses the length bar 2 of two Φ 8mm normal diameters for measuring.During measurement by two length bars 2 respectively by being put in the teeth groove that workpiece 4 endoporus are relative, then with being disposed across inner support in workpiece 4 endoporus 1, support length bar 2, inner support 1 is perpendicular with length bar 2.The straight rod member that is adjustable in length because of inner support 1 in the present invention, inner support 1 stage casing is provided with adjustable diameter and screw adjusting structure, regulates inner support 1 to make straight top, two ends length bar 2 outer walls, directly forms length bar 2 with the measurement structure of internal tooth location swelling.Described length measurer 3 is outside micrometer, during measurement, the oriented length bar 2 of the common contact of outside micrometer two ends gauge head being made to internal tooth interrod spacing measures, the value measuring is added to the diameter value of two length bars 2, just obtain the interrod spacing physical size of workpiece 4 measured internal tooths.In the present invention, length bar 2 is by inner support 1 rigid support, and position stability, measures accurately.On the other hand because of simple in structure, install easily, it is convenient to detect, be highly suitable for production scene for detection of.Due to the supporting cubing in production scene, have ready conditions and accomplish timely detection, avoid occurring overproof in batches quality accident.
