Description
Technical field
The utility model belongs to propeller inspection technology field, and in particular to a kind of propeller shaft hole taper and linearity inspection
Experiment device.
Background technology
In propeller manufacturing industry, axis hole taper and the linearity requirement of propeller are extremely strict but check system is very single
One.Generally tested now by way of axis hole model coordinates with clearance gauge come the linearity to axis hole, and axis hole size is then
Measured with inside micrometer, reference is used as with model line.Due to propeller shaft bore dia and different every kind of propeller of length
One piece of model will be processed, so in production not only waste of materials but also the inspection experience to reviewer have it is very high will
Ask, once occurring during operator's processing wrong and reviewer does not test out, it will produced to company in economic and fame
Raw immeasurable influence, also master blank is that the stress that exists in sheet material cut out by gas welding is easily deformed, due to
Above-mentioned reason causes the problem of model linearity is undesirable virtually to add risk to product quality.
For these reasons, the particularity that my company technique personnel produce product according to company devises a kind of propeller shaft
Hole taper and linearity verifying attachment, the apparatus structure are simple, and precision is high, easy to operate, and defective work has been reduced or avoided and has gone out
The risk of factory, is worth promoting the use of in the same industry.
The content of the invention
The purpose of this utility model is to provide a kind of propeller shaft hole taper and linearity verifying attachment, above-mentioned to solve
The problem of being proposed in background technology.
To achieve the above object, the utility model provides following technical scheme：A kind of propeller shaft hole taper and linearity
Verifying attachment, including upper arm, taper linearity on-gauge plate, adjusting rod, knurled nut and adjustable measurement bar, the upper arm passes through tight
Fixing bolt is fixedly connected with taper linearity on-gauge plate, and the taper linearity on-gauge plate is abutted against on propeller hub, described
One end of adjusting rod is arranged in the side countersunk head silk hole of taper linearity on-gauge plate, and the other end of adjusting rod is threaded with
Adjustable measurement bar and between the two by knurled nut's adjustable range, the knurled nut is threadedly coupled with adjustable measurement bar, institute
The end for stating adjustable measurement bar is provided with measurement head.
It is preferred that, the blade type that the taper linearity on-gauge plate is width 1mm with one side that propeller hub is abutted.
Technique effect of the present utility model and advantage：The propeller shaft hole taper and linearity verifying attachment, can be saved
Cost, is reduced or avoided defective work and dispatches from the factory.Because the device is generally applicable, greatly reduces a kind of propeller and make a model
Wasting phenomenon, it is ensured that product quality., can and the utility model is reasonable in design, simple in construction, precision is high, easy to operate
Promoted the use of in the same industry.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
The utility model provides a kind of propeller shaft hole taper and linearity verifying attachment as Figure 1-3, including
Upper arm 1, taper linearity on-gauge plate 3, adjusting rod 4, knurled nut 5 and adjustable measurement bar 6, the taper linearity on-gauge plate 3
The blade type for being width 1mm with one side that propeller hub 8 is abutted, the upper arm 1 passes through fastening bolt 2 and taper straight line scale
Quasi- plate 3 is fixedly connected, and the upper arm 1 is connected by parallels 9 with propeller hub 8, and the taper linearity on-gauge plate 3 is abutted
On propeller hub 8, one end of the adjusting rod 4 is arranged in the side countersunk head silk hole of taper linearity on-gauge plate 3, described
The other end of adjusting rod 4 is threaded with adjustable measurement bar 6 and uses knurled nut's adjustable range between the two, the knurled nut
5 are threadedly coupled with adjustable measurement bar 6, and the end of the adjustable measurement bar 6 is provided with measurement head 7.
Operation principle：Upper arm 1 is fixed together with taper and linearity on-gauge plate 3 with fastening bolt 2, according to spiral shell
The size and the suitable adjusting rod 4 of propeller hub length selection and adjustable measurement bar 6 of oar axis hole are revolved, the adjusting rod 4 of selection is screwed in into cone
In the side countersunk head silk hole of degree and linearity on-gauge plate 3, note：Have to tighten and lean on, examined after installation with square
Whether taper and linearity on-gauge plate 3 are vertical with adjusting rod 4, examine Vertical Square to be continuing with.
Through measure it is qualified after adjustable measurement bar 6 is screwed into adjusting rod 4 with knurled nut 5, taper and linearity on-gauge plate 3
