Abstract
The utility model discloses a kind of new internal spline keyway detection means, it includes shank shaft member, detection shaft member, shank shaft member and detection shaft member coaxial line arrangement and integrated molding, the diameter of shank shaft member is less than the diameter of detection shaft member, the keyway to match with key is provided with detection shaft member, the positioning hole for being radially distributed and being located in keyway is additionally provided with detection shaft member, the hole slot to match with positioning hole is provided with key, key is installed in the keyway of detection shaft member using bolt；Inner spline groove progress can be rapidly performed by, only need reciprocal twitch shank shaft member and rotate shank shaft member, both it can quickly detect whether internal spline size meets the requirements, it is simple to operate, and the detection of more inner spline grooves can be both adapted to by changing the key to match with inner spline groove.
Description
Technical field
It the utility model is related to a kind of machining auxiliary equipment, more particularly to a kind of internal spline keyway detection means.
Background technology
In internal keyway processing and manufacturing field, the bad detection of width and symmetry of usual keyway, but due to flat key groove in itself
It is the wide positioning of key, symmetry requires very high, and because of the structural limitation of portioned product, some cubings commercially can't buy；If no
Good cubing uses, and because that can not know the accurate data of product, the probability for causing product qualified is relatively low, and my company is being passed through constantly
Grope and improve, manufacture and design a detection instrument simple to operate, precision is high that comes out, and can be with Reusability, comprehensive profit
With rate height.
The content of the invention
For solve the deficiencies in the prior art, the purpose of this utility model be to provide it is a kind of be suitable for internal spline keyway detection
Instrument, and can easily be changed with repeated multiple times use.
To realize above-mentioned technical purpose, technical scheme is as follows used by the utility model.
A kind of new internal spline keyway detection means, it includes shank shaft member, detection shaft member, shank shaft member and detection shaft member
Coaxial line is arranged and integrated molding, and the diameter of shank shaft member is less than the diameter of detection shaft member, detect be provided with shaft member with
The keyway that key matches, the positioning hole for being additionally provided with shaft member and being radially distributed and being located in keyway is detected, is set on key
There is the hole slot to match with positioning hole, key is installed in the keyway of detection shaft member using bolt.
The keyway that several are arranged along its circumferencial direction uniform intervals and size is different is offered in detection shaft member；
Matched using key is changed with corresponding keyway, so as to adapt to the detection of various sizes of inner spline groove.
The material that above-mentioned detection means uses improves the hardness of detection means, and improve wearability for 20CrMnTiH
Energy.
It is advantageous in that compared with prior art for utility model, inner spline groove progress can be rapidly performed by, it is only necessary to
Reciprocal twitch shank shaft member and rotation shank shaft member, both can quickly detect whether internal spline size meets the requirements, grasp
Make key that is simple, and can matching by replacing with inner spline groove, both be adapted to the detection of more inner spline grooves.
Brief description of the drawings
In order to illustrate the embodiments of the present invention more clearly, the required accompanying drawing used in embodiment will be done simply below
Introduce, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for ordinary skill people
For member, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation that the utility model matches with workpiece.
Fig. 2 is structural representation of the present utility model.
It is denoted as in figure：
10th, workpiece；20th, detection means；210th, shank shaft member；220th, shaft member is detected；230th, positioning hole；240th, key.
Embodiment
With reference to the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art are not under the premise of creative work is made, the every other reality that is obtained
Example is applied, belongs to the scope of the present invention.
Referring to accompanying drawing 1,2, a kind of new internal spline keyway detection means 20, it includes shank shaft member 210, detection shaft member
220, shank shaft member 210 and detection shaft member 220 coaxial line arrangement and integrated molding, the diameter of shank shaft member 210 are less than inspection
The diameter of shaft member 220 is surveyed, detects and the keyway to match with key 240 is provided with shaft member 220, detects and is additionally provided with shaft member 220
Radially it is distributed and the positioning hole 230 in the keyway, is provided with the hole slot to match with positioning hole 230 on key 240, profit
Key 240 is installed in the keyway of detection shaft member 220 with bolt.
Referring to accompanying drawing 1, when checking workpiece 10, using the key to match with workpiece internal keyway and push-to is crossed into bolt
It is installed at detection shaft member, worker holds shank shaft member 220 and inserted a key into the internal spline of workpiece 10, reciprocal twitch handle
Portion's shaft member, detect whether to stop or with the presence or absence of skew, and judged whether the internal spline of workpiece 10 meets requirement of dispatching from the factory.
For the further keyway scope for improving detection means 20, detect and offer several along its circumference in shaft member 220
The keyway that direction uniform intervals arrange and size is different；Matched using key is changed with corresponding keyway, so as to adapt to not
With the detection of the inner spline groove of size.
Detection means 20 provided by the utility model be adaptable to sizes inner spline groove detection, it is only necessary to change with
The key to match, it is simple to operate, and detection efficiency is high.
For the material that above-mentioned detection means uses for 20CrMnTiH, its processing technology includes blanking（Material 20CrMnTiH）
→ Vehicle Processing → drilling and tapping → cylindrical grinding → cuts keyway → cuts flat key → press-fitting edge flat key → hexagon socket head cap screw and fixes → tri- seats
Mark detection width of keyway and symmetry.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or using the present invention；
A variety of modifications to these embodiments will be apparent for those skilled in the art, defined in the present invention
General Principle can not depart from the present invention spirit or scope in the case of, realize in other embodiments.Therefore, originally
