The drawback of one is that my company is to process axis hole with cone hole machine special equipment, and equipment is feed in axis hole, when needs are surveyed
It is accomplished by when taking measurements being unloaded by the boring cutter bar of cone hole machine special purpose machine tool and hanging axis hole, which not only adds the labor of workman
Fatigue resistance, also add the process time of product, and the precision simultaneously for product also produces impact, wants to produce high accuracy and produces
Product are necessary for improving traditional axis hole metering system, and inside micrometer is improved by my company on this basis, makes knife bar exist
Time in axis hole can also measurement axis hole dimension accurately, to this end, it is proposed that a kind of axis hole measurement apparatus.
Summary of the invention
The purpose of this utility model is to provide a kind of axis hole measurement apparatus, with asking of solving to propose in above-mentioned background technology
Topic.
For achieving the above object, this utility model following technical scheme of offer: a kind of axis hole measurement apparatus, including propeller hub,
The middle part of described propeller hub is machined with axis hole, and described axis hole is internally installed boring cutter bar, and the outside of described boring cutter bar is provided with axis hole
Measurement apparatus, described axis hole measurement apparatus measurement position is at axis hole full-size, and described axis hole measurement apparatus includes U-shaped chi
Frame, the left side beam arm of described U-shaped chi frame is provided with fixing scale bar, and the left end of described fixing scale bar is provided with microdrum, institute
The two ends stating U-shaped chi frame are provided with extension bar, and the outer end of described extension bar is respectively connected with measurement head.
Preferably, the inner chamber of described extension bar is provided with blind hole, and the inwall of blind hole is provided with female thread, connecing of described measurement head
The external screw thread matched with female thread it is provided with at Tou.
Preferably, on the left of described U-shaped chi frame, beam arm is provided with fixing scale bar and the scale groove of microdrum the most bonding
There is luminescent powder.
Compared with prior art, the beneficial effects of the utility model are: this axis hole measurement apparatus, need first will before measurement data
Measure the two ends wiped clean of head, it is to avoid having dirty affects certainty of measurement, will be corresponding further according to propeller shaft hole process
Extension bar is received on U-shaped chi frame, and attention is accomplished symmetrical when installing extension bar as far as possible, makes the U-shaped portion of U-shaped chi frame as far as possible
Position is in centre, and receives the other end of extension bar by measuring head, finally by fixing scale bar and microdrum subsidiary, this
Device can on the premise of not removal knife bar measurement axis hole dimension, decrease the labor intensity of workman, reduce workman loader
The time of dress, improve the precision of product, this measurement apparatus is promoted the use of after being worth simultaneously.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is this utility model partial top structural representation；
Fig. 3 is this utility model part-structure schematic diagram.
In figure: 1 U-shaped chi frame, 2 fix scale bar, 3 microdrums, 4 extension bars, 5 measure head, 6 axis hole measurement apparatus, 7 borings

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1-3, a kind of technical scheme of this utility model offer: a kind of axis hole measurement apparatus, including propeller hub 8, institute
The middle part stating propeller hub 8 is machined with axis hole 9, and described axis hole 9 is internally installed boring cutter bar 7, and the outside of described boring cutter bar 7 is provided with axle
Hole measurement device 6, described axis hole measurement apparatus 6 measures position at axis hole full-size, and described axis hole measurement apparatus 6 includes
U-shaped chi frame 1, the left side beam arm of described U-shaped chi frame 1 is provided with fixing scale bar 2, and the left end of described fixing scale bar 2 is provided with
Microdrum 3, the two ends of described U-shaped chi frame 1 are provided with extension bar 4, and the outer end of described extension bar 4 is respectively connected with measurement 5.
Further, the inner chamber of described extension bar 4 is provided with blind hole, and the inwall of blind hole is provided with female thread, described measurement 5
Joint be provided with the external screw thread matched with female thread, by the blind hole matched and joint, recycle threaded, more
