Abstract
The invention relates to a depth detection tool of a shaft key groove, belonging to the technical field of measurement tools, in particular to the depth detection tool of the shaft key groove, wherein a fastening screw (7) is used for fixing a dial indicator (5) at the upper opening part of a V-shaped locating block (1) with a method for tightly pressing an opening sleeve (6); a depth measurement rod (2) is fixed in a hole in the middle of the V-shaped locating block (1); and the top of the depth measurement rod (2) is always in contact with a contact of the dial indicator (5). According to the depth detection tool of the shaft key groove, disclosed by the invention, relative reference is not required; and the depth detection tool is more convenient to use and is hardly influenced by external factors to result in errors in measuring a work-piece.
Description
Technical field
The present invention relates to a kind of generic key groove depth testing tool, belong to the survey instrument technical field.
Background technology
At present, measurement axis generic key groove depth mainly is to use the method for vernier caliper or pit gauge to measure, yet; Since the degree of depth of keyway be with the cylindrical bus of the farthest axle on keyway plane as benchmark, add to be cut man-hour at keyway and remove and be in bus above the keyway, so; When measuring often with the benchmark the most of the bus on the axle of keyway bottom, so, when measuring; Sometimes must repeated multiple times measure, guaranteeing to measure the actual grade of keyway, so; Not only cumbersome, owing to receive the influence of extraneous factor, there is bigger measuring error sometimes simultaneously.
Summary of the invention
The objective of the invention is to: a kind of generic key groove depth testing tool is provided, overcomes existing keyway depth survey instrument, using the defective that existing use is cumbersome and be easy to receive the extraneous factor influence survey instrument error that causes.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of generic key groove depth testing tool; It is made up of V-type locating piece, Sounding Rod, plug screw, stage clip, dial gauge, opening sleeve, trip bolt, auxiliary arm, sliding bar, guide finger, pinion stand, gear, location foot rest, institute; It is characterized in that: said dial gauge is installed in the position suitable for reading of V-type locating piece through opening sleeve, and trip bolt is installed in the side of the upper oral part of V-type locating piece, and trip bolt is through compressing the method for opening sleeve; Dial gauge is fixed on the upper oral part of V-type locating piece; Described Sounding Rod has the axle that step is takeed in the middle of being, on the top of Sounding Rod step shoulder stage clip is installed, and stage clip and the Sounding Rod V-type below the V-type locating piece is left in the hole that is installed to V-type locating piece bottom the shelves; Plug screw is through the shoulder of the step above the Sounding Rod; Sounding Rod is fixed in the middle hole of V-type locating piece, and simultaneously, the top of assurance Sounding Rod remains with the contact of dial gauge and contacts; Simultaneously, guarantee that again stage clip has certain compression; In the bar portion of V-type locating piece an auxiliary arm is installed behind; Described sliding bar is shaped on gathering sill along its cylindrical generatrix direction; Sliding bar is installed in the end of auxiliary arm through gathering sill and guide finger; And the angular bisector at the V-arrangement angle of the center line of sliding bar and V-type locating piece is parallel to each other, and installs and fixes pinion stand in the bottom of sliding bar, and a kind of pitch wheel is installed on pinion stand symmetrically; Each gear is connected fixing with a location foot rest, and two location foot rests are all the time about the guide pole symmetry.
Principle of work of the present invention is: in use need only the V-type of V-type locating piece be opened on the cylindrical that grade position rides over axle, and make on the guide pole two location foot rests be fastened on the both sides of keyway, Sounding Rod just aligns keyway simultaneously; Read the numerical value of dial gauge at this moment; Then the V-type locating piece is ridden over any part of a cylindrical, simultaneously, the head of Sounding Rod contacts with the cylindrical any part of axle; And read the reading value of dial gauge at this moment, this difference of twice is exactly the depth value of keyway.
Beneficial effect: the present invention need not relative datum, uses more conveniently, is not vulnerable to the extraneous factor influence institute measuring workpieces that causes and produces an error.
