Abstract
The utility model provides a poor and plane degree measuring apparatu of mold core of hub, belongs to measuring instrument technical field, includes the chuck and the worm wheel that set up with the axle center, the worm wheel sets firmly in the chuck bottom, the chuck bottom is rotated with the base through the bearing and is connected, the worm wheel has set the worm. In order to improve the numerical value accuracy, reduce to measure the degree of difficulty, this device specially improves the meter, changes the fixed meter of centre gripping into by manual location survey table. Change location benchmark of original measuring, this location benchmark and follow -up car processing location benchmark are unanimous.
Description
Technical field
The utility model belongs to surveying instrument technical field, is particularly related to a kind of core rod difference and flatness measuring instrument of wheel hub.
Background technology
Core rod difference and the traditional measurement mode of flatness are: rely on the inner bottom surface of product and location, side, measuring surface directly contacts with dial gauge, and employing is manually fixed, rotate to measure the poor and flange formation degree of core rod.Because the high inner bottom surface of product height is little, and during uneven measurement, product is unstable, causes measurement numerical value inaccurate, measures difficulty large.
Utility model content
The purpose of this utility model is to overcome the above-mentioned defect mentioned and deficiency, and provides a kind of core rod difference and flatness measuring instrument of wheel hub.
The technical scheme that the utility model realizes the employing of its object is as follows.
The core rod difference of wheel hub and a flatness measuring instrument, comprise chuck and the worm gear of concentric setting; Described worm gear is fixedly arranged on bottom chuck; Be connected with base rotation by bearing bottom described chuck; Described worm gear is equipped with worm screw.
Described worm screw is arranged in base; Described worm end is equipped with manual handle.
Described chuck top is provided with claw; Described claw has 3 at least, and circumference is uniform.
The core rod difference of wheel hub and a flatness measuring instrument, is characterized in that, also comprise locating piece; Described locating piece is fixed on chuck top by bolt.
Described locating piece is the right cylinder of hollow.
Described claw is located between locating piece and chuck.
Described chuck hollow is arranged.
The core rod difference of wheel hub and a flatness measuring instrument, also comprise two dial gauges.
This application of installation is measured in wheel hub product the core rod difference of long pole series of products and flange formation degree, high-temperature product can be measured, improve core rod difference and the flatness measurement accuracy of my company's long pole series of products, improve checkability, promote me and take charge of the market competitiveness in industry.
In order to improve Numerical accuracy, reduce to measure difficulty, this device spy improve meter, changed into grip meter by manual positioning meter.Change a positioning datum of original measurement, this positioning datum is consistent with follow-up Vehicle Processing positioning datum.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment one.
The present embodiment is in order to measure core rod difference and the flatness of outer ring product.
The core rod difference of wheel hub and a flatness measuring instrument, comprise chuck 5 and the worm gear 7 of concentric setting; Described worm gear 7 is fixedly arranged on bottom chuck 5.Be rotationally connected by bearing 6 and base 8 bottom described chuck 5.Described worm gear 7 is equipped with worm screw 9.
Rotary worm 9, thus drive worm gear 7 to rotate, chuck 5 synchronous axial system.
Described worm screw 9 is arranged in base 8; Described worm screw 9 end is equipped with manual handle 10.
Described chuck 5 top is provided with claw 4; Described claw 4 has 3 at least, and circumference is uniform.Described claw 4 the inner is provided with boss.Boss contacts the inwall of outer ring product, thus outer ring, location product.Claw 4 is in order to fixing outer ring product.Described chuck 5 hollow is arranged.
The core rod difference of wheel hub and a flatness measuring instrument, also comprise two dial gauges.
The present embodiment, by the fixing outer ring product of claw 4, then shakes manual handle 10, makes outer ring product smooth rotation, adjusts to finally by two positions the relevant data that suitable dial gauge 1 highly records core rod difference and flatness.
Embodiment two.
The present embodiment is in order to measure core rod difference and the flatness of inner ring product.
The core rod difference of wheel hub and a flatness measuring instrument, also comprise locating piece 2; Described locating piece 2 is fixed on chuck 5 top by bolt 3.
Described locating piece 2 is the right cylinder of hollow.Described claw 4 is located between locating piece 2 and chuck 5.
The support of inner ring product is by the acting in conjunction of claw 4 and locating piece 2.Claw 4 boss contacts the outer wall of inner ring product long-neck, the flange face of the top braces inner ring product of locating piece 2, thus fixing inner ring product.
All the other are identical with embodiment one for the present embodiment, repeat no more.
The utility model is illustrated according to embodiment, and under the prerequisite not departing from present principles, this device can also make some distortion and improvement.It should be pointed out that and all drop on the technical scheme that all employings are equal to replacement or the mode such as equivalent transformation and obtain in protection domain of the present utility model.
