Abstract
The invention discloses a shaft key groove depth detection tool. A dial gauge is arranged at the upper opening part of a V-shaped positioning block through an opening sleeve, namely the dial gauge is fixed at the upper opening part of the V-shaped positioning block by a method of compacting the opening sleeve by using a fastening screw; an upper pressure spring is arranged at the upper part of the step shoulder of a sounding rod; the pressure spring and the sounding rod are arranged into holes at the bottom of the V-shaped positioning block from a V-shaped crotch below the V-shaped positioning block; the sounding rod is fixed in a hole in the middle of the V-shaped positioning block by using a screw plug through the step shoulder of the sounding rod; and meanwhile, the top of the sounding rod is in contact with a contact of the dial gauge all the time, and certain compression of the pressure spring is ensured.
Description
Technical field
The present invention relates to a kind of class testing tool, particularly a kind of generic key groove depth testing tool belongs to the survey instrument technical field.
Background technology
At present, the measurement axis class detects the degree of depth and mainly is to use the method for vernier caliper or pit gauge to measure, yet, because the degree of depth of keyway is as benchmark with the cylindrical bus of the farthest axle on keyway plane, 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 be subjected to 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 be subjected to 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 by the V-type locating piece, Sounding Rod, plug screw, stage clip, dial gauge, opening sleeve, trip bolt is formed, described dial gauge is installed in the position suitable for reading of V-type locating piece by opening sleeve, the side of the upper oral part of trip bolt V-type locating piece, trip bolt is by 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, top at Sounding Rod step shoulder is equipped with stage clip, 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 by the shoulder of the step above the Sounding Rod, Sounding Rod is fixed in the middle hole of V-type locating piece, 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.
Principle of work of the present invention is: in use the V-type of V-type locating piece need only be opened grade position ride over the axle cylindrical on, and make the same portion of Sounding Rod align keyway, 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 reads the reading value of dial gauge this moment, and this difference of twice is exactly the depth value of keyway.
Beneficial effect: the relative datum that need not of the present invention, more convenient in the existing use of use, be not vulnerable to the extraneous factor influence institute measuring workpieces that causes and produce an error.
Description of drawings
Fig. 1 is a structure principle chart of the present invention;
Shown in the figure: 1, V-type locating piece; 2, Sounding Rod; 3, plug screw; 4, stage clip; 5, dial gauge; 6, opening sleeve; 7, trip bolt; A, workpiece.
Embodiment
Dial gauge (5) is installed in the position suitable for reading of V-type locating piece (1) by opening sleeve (6), use trip bolt (7) by compressing (6) method of opening sleeve, dial gauge (5) is fixed on the upper oral part of V-type locating piece (1), stage clip (4) is installed on top at Sounding Rod (2) step shoulder, stage clip (4) and the V-type of Sounding Rod (2) below V-type locating piece (1) are left in the hole that is installed to V-type locating piece bottom the shelves, take on by the step above the Sounding Rod (2) with plug screw (3), Sounding Rod (2) is fixed in the middle hole of V-type locating piece (1), simultaneously, the top that guarantees Sounding Rod (2) remains with the contact of dial gauge (5) and contacts, simultaneously, guarantee that again stage clip (4) has certain compression.
Claims (2)
1. axle 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, it is characterized in that: trip bolt (7) is fixed on dial gauge (5) upper oral part of V-type locating piece (1) by compressing (6) method of opening sleeve;
2. according to claims 1 described a kind of generic key groove depth testing tool, it is characterized in that: Sounding Rod (2) is fixed in the middle hole of V-type locating piece (1), and the top of Sounding Rod (2) remains with the contact of dial gauge (5) and contacts.
