Abstract
The utility model belongs to a measuring device, and relates to a step deep hole coaxiality measuring device which is used for detecting an inner ring groove with a large depth from an end surface of a part. The measuring device comprises a measuring rod [1], a base sleeve [2], a measuring claw [3], and an indicating dial gauge; internal threads of the base sleeve [2] are in precise cooperation with external threads of the measuring rod [1]; double cones coaxial with the measuring rod [1] are cooperated with two angles on the measuring claw [3]; and a dial gauge connector [6] penetrates through a dial gauge fixed sleeve and contacts the tip of the measuring rod. The measuring cone rod is a double-cone structure; the double cones respectively work on two angle surfaces of the measuring claw; and no deformation and no error in an indicating value are generated when the measuring claw is quite long. The gauge is suitable when the ratio of the inner diameter to the inner ring groove is large, and is suitable for measuring the diameter of the inner ring groove which is provided with the 176 mm depth from the end surface of the ring groove. The measuring device is convenient in operation and high in measuring reliability, and improves the efficiency by 5 times compared with the caliper. The measuring device can be used for the absolute measurement and comparison measurement.
Description
Technical field
The utility model belongs to measurement mechanism, relates to a kind ofly for detection of apart from the darker size inner groove of part end face, and has the measurer of brand new.
Background technology
Measure at present inner groove size and adopt calliper.Because calliper belongs to two point measurements, when measurement, be not easy to measure diameter of a circle.Need to repeatedly find diameter, useless power when useless, accuracy of measurement is low.
Summary of the invention
The purpose of this utility model is: adopt the measurer of a kind of three-jaw location to make to measure more fast, stablize.
The technical solution of the utility model is: a kind of step deep hole coaxiality check fixture, it comprises measuring staff 1, base cover 2, measuring jaw 3, instruction clock gauge, base overlaps the external thread precision-fit on 2 internal threads and measuring staff 1, the coaxial double cone of measuring staff 1 matches with two angle faces on measuring jaw 3, and clock gauge joint 6 contacts with measuring staff top through clock gauge fixed cover.
Pilot hole on guidepost on measuring jaw 3 and base cover 2 is circular.
On base cover 2, be provided with diclinic pin ratchet 12.
The utility model has the advantages that: the simple operation of the utility model measurement mechanism, measure reliability high, efficiency is compared caliper measurements can improve 5 times, utilizes this measurement mechanism to carry out absolute measurement and to compare and measure, and makes to measure more fast, stablizes.
Brief description of the drawings
Fig. 1 is the front elevation of the utility model step deep hole coaxiality check fixture;
Wherein, 1-measuring staff, 2-base cover, 3-clock gauge fixed cover, 6-clock gauge gauge head, 7-main body bar R type groove, 8-guider screw, 9-round head screw, 10-ratchet bonnet, 11-ratchet chi dish, 12-ratchet pin, 13-spring, 14-trip bolt.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Refer to Fig. 1, the utility model step deep hole coaxiality check fixture comprises measuring staff 1, base cover 2, measuring jaw 3, instruction clock gauge, base overlaps the external thread precision-fit on 2 internal threads and measuring staff 1, the coaxial double cone of measuring staff 1 matches with two angle faces on measuring jaw 3, and clock gauge joint 6 contacts with measuring staff top through clock gauge fixed cover.Base cover 2 is socketed on measuring staff 1, and clock gauge fixed cover is arranged on main body rod end head, and clock gauge joint is through clock gauge fixed cover and main body masthead end in contact.Guidepost on measuring jaw 3 and base cover 2] pilot hole be circle.On base cover 2, be provided with diclinic pin ratchet 12.
Adopt the coaxial double cone of measuring staff 1 to match with two angle faces on measuring jaw 3, when Anti-clockwise rotational deformation ratchet 8, external thread on measuring staff 1 overlaps 2 internal threads with base and acts on and moving forward mutually, and three measuring jaws 3 stretch out and enter on annular groove internal diameter to external diameter direction under the reach effect of measuring staff 2 simultaneously.Clock gauge gauge head 6 contacts on measuring staff breech face, and instruction clock gauge shows the size that measuring staff moves.Measuring staff 1 circular cone design machining angle is 53 ° 7 ' 48 ", the angle faces on measuring jaw 3 is corresponding with measuring staff 1, moves radially size so the size that measuring staff moves is exactly measuring jaw 3.Diclinic pin ratchet makes dynamometry more stable.Cone bar moves forward and backward by instruction clock gauge and shows survey measurements precision is improved.
Anti-clockwise rotational deformation ratchet 8, two angle faces when the external thread on measuring staff 1 acts on precession forward mutually with the internal thread on base cover 2 on two circular cone promotion measuring jaws 3 are released measuring jaw 3 outward radials, and reading on instruction clock gauge 6, completes measurement; Turn-knob ratchet 8 clockwise, measuring staff 2 retreats, and shrinks spring 13 measuring jaw 3 is inwardly recovered to reference position.
This measurement mechanism can solve degree of depth large scale, the measurement of the inner groove that annular groove and footpath, end ratio are large.Before measurement, first proofread the numerical value of initial size and the relative ring gauge of instruction clock gauge with ring standard gauge.
Three measuring jaws 3 are put in master ring, will be indicated clock gauge to zero.Knob ratchet 8, overlaps under 2 internal thread effects at measuring staff 1 external thread and base counterclockwise, and when measuring staff 1 moves forward, two circular cones promotion measuring jaw 3 radial levels move to outward on inner ring groove of part diameter, then under turn-knob ratchet 3-5, observe instruction clock gauge data.Data when initial by check gauge and the difference that measures the size after annular groove are the size of inner groove.This measurement mechanism structure is rationally unique, and quick and precisely, it is more accurate to compare and measure in operation.
