Axiality is that guarantee equipment is long-term, an important parameter of stable operation, and existing workpiece coaxiality adjusting method is: the axis of axiality positioning tool is decided to be datum axis, will wait to adjust workpiece to put into axiality tool, and utilize image measurer to position, adjusts.Problems such as adjustment, needing turning of work piece in position fixing process, contrast adjustment is carried out to workpiece different angles, coordinate, have that positioning tool is easy to wear, workpiece is easily stuck in frock.
Summary of the invention
The present invention proposes to overcome the shortcoming existed in prior art, its objective is and provides a kind of axiality to adjust positioner.
Technical scheme of the present invention is:
A kind of axiality adjustment positioner, comprise base plate and bearing block, through hole is formed in the middle of base plate, shoulder hole is formed in the middle of described bearing block, upper flange is formed at bearing block top, bearing block is sticked in the through hole of base plate by upper flange, and truncated cone-shaped base through screws is fixedly connected with the bottom surface of bearing block; The boss portion of base engages with the shoulder hole hypomere of bearing block, and form different diameter hole in the middle of base, cylinder is fixedly connected with the bottom surface of base by stud; Column type jack-up block is installed in the different diameter hole of base, and with base matched in clearance, jack-up block bottom surface forms lower flange, middle Formation cross-section is the I-shaped hole of I shape, and the piston rod of cylinder stretches in I-shaped hole, and is fixed by nut and jack-up block, cylindrical shape positioning seat is installed in the shoulder hole of bearing block, form the reducing through hole matched with workpiece in the middle of positioning seat, upper end forms flange part, and two bearings are installed in the gap, left and right of positioning seat and bearing block.
The bottom surface of described flange part is higher than the upper end face of upper flange.
The invention has the beneficial effects as follows:
The present invention adopts duplex bearing, by rolling bearing, workpiece is rotated together with positioning tool, without relative motion between workpiece and positioning tool, avoids friction, thus avoids the wearing and tearing of locating tool; Reduce the gap between positioning tool and workpiece, improve Adjustment precision, promote an assembly qualified rate; Adopt pneumatic uplifting device, solve because frock precision is high, little with work pieces mate gap, cause the stuck problem in positioning tool of workpiece, be convenient to workpiece to lift.
