Abstract
The utility model discloses a high-precision measuring tool for measuring the depth of an annular groove of an inner hole, which comprises a standard vernier caliper (without a depth rod), a base, a depth claw and a rivet. The high-precision measuring tool can measure the depth of the annular groove of the inner hole with the groove depth less than or equal to 300mm and the groove width more than or equal to 1.2mm, and overcomes the defects of the ordinary measuring tool that the measurement precision is low and the measurement can not be carried out easily. Moreover, the high-precision measuring tool is convenient to use and has high measurement precision, simple structure and low cost.
Description
Technical field
The utility model relates to a kind of measurer of measuring endoporus ring groove depth dimensions, particularly a kind of high precision measurer of measuring endoporus ring groove depth dimensions.
Background technology
Detection technique is the important means that guarantees mechanical product quality, and the dimensional accuracy of part is the important symbol of mechanical product quality.On some parts, the degree of depth is comparatively difficult always less than the ring groove depth dimensions detection of 3mm greater than 100mm, groove width, and particularly the ring groove that some position accuracy demand are very high more is difficult to guarantee to detect quality.Ordinary measring tool is difficult to measure the degree of depth of small size endoporus ring groove, and its testing process is comparatively cumbersome, and it is big to detect error.For the endoporus ring groove of groove width less than 3mm, ordinary measring tool can not detect it substantially.
Summary of the invention
The purpose of this utility model is: the measurer that a kind of high-precision measurement endoporus ring groove depth dimensions is provided, can realize detection, to overcome the defective of existing ordinary measring tool accuracy of detection difference and detection difficult to the endoporus ring groove depth dimensions of groove depth≤300mm, groove width 〉=1.2mm.
The utility model is to constitute like this, and it comprises standard vernier caliper (not containing degree of depth bar), base, rivet, degree of depth pawl.Standard vernier caliper scale 1 is connected by three rivets 4 with the base 2 of high rigidity, hard high-wearing feature degree of depth pawl 3 is packed in the vernier caliper degree of depth bar groove, itself and base 2 are made up processing, guarantee the consistance of size, machining back degree of depth pawl 3 can move in standard vernier caliper degree of depth bar groove.According to concrete operating position, this measurer can realize that its accuracy of detection can reach 0.02mm to the detection of the endoporus ring groove depth dimensions of groove depth≤300mm, groove width 〉=1.2mm.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model measurer.
Embodiment
With three rivets 4 standard vernier caliper scale 1 is connected with the base 2 of high rigidity, hard high-wearing feature degree of depth pawl 3 is packed in the vernier caliper degree of depth bar groove, degree of depth pawl 3 and base 2 are made up processing, guarantee the consistance of size.Machining back degree of depth pawl 3 can move in standard vernier caliper degree of depth bar groove.This measurer can realize that accuracy of detection can reach 0.02mm to the detection of the endoporus ring groove depth dimensions of groove depth≤300mm, groove width 〉=1.2mm.
Claims (1)
1. high precision measurer of measuring endoporus ring groove depth dimensions, comprise standard vernier caliper, base, degree of depth pawl and rivet, it is characterized in that: standard vernier caliper scale (1) is connected by three rivets (4) with the base (2) of high rigidity, the degree of depth pawl (3) of hard high-wearing feature is positioned in the degree of depth bar groove of standard vernier caliper, can move in the degree of depth bar groove of standard vernier caliper.
