Background technology:
At present, design foraminate shaft-like workpiece in radial direction, for the little axle of aperture assembling the time, employing be the location and press-fited for two steps and finish.At first, by positioning core axle with workpiece with press-fit tool and be seated, take off positioning core axle, the assembling mandrel that little axle is housed is packed into to press-fit in the tool, forcing press is gone into little axial compression in the aperture by the assembling mandrel is applied pressure at right angle, takes off the assembling mandrel, finishes assembling.This assembling mode is higher with the required precision of assembling mandrel to positioning core axle, and because frequency of utilization is higher, and mandrel easily weares and teares, and this assembling mode is not easy to monitor the abrasion condition of mandrel, causes press-fiting in batch the appearance of disalignment situation; Simultaneously, finish, press-fit efficient and be difficult to improve, when production in enormous quantities is assembled, have limitation owing to locating and press-fiting in two steps.
Summary of the invention:
The utility model is that the shortcoming that overcomes the prior art existence proposes, and purpose is to provide a kind of mechanical industry minor diameter class axle, the accurate interference assembling device in hole.
The technical solution of the utility model is: a kind of small diameter shaft class interference assembling device, comprise that the axial location seat is connected with the axial limiting seat and be fixed on the pedestal platform by screw as the location benchmark, the guiding drill bushing is installed on the leading truck, and the fixed guide frame is fixed on the pedestal platform.
The radial location lever dolly is connected with the pedestal platform, the radial location pin is installed in the axial limiting seat along little axle location drill bushing, the radial location lever in axial direction inserts in the axial limiting seat, radial location lever one end blocks the radial location pin, and lever pin inserts radial location lever dolly and radial location lever successively.
Both ends of the spring is hung on spring set bolt and the radial location lever, press-fiting bar and pressure connecting rod penetrates the flexible connection piece respectively and flexibly connects piece down, press-fiting little axle is installed in the drill bushing of little axle location, press-fit bar and insert in the guiding drill bushing of leading truck, the pressure pitman is connected with pneumatic press.
Described going up flexibly connects piece and flexibly connect piece down, and be fastening with trip bolt.
Described radial location pin exposes the axial limiting seat under the effect of the spring force of spring.
The utility model has the advantages that: once be installed and realize accurate location to workpiece, by using the calibration rod to press-fiting body with detent mechanism is calibrated before press-fiting, aperture and little have good axiality when having guaranteed to press-fit; Simultaneously, the effect of universal joint has been played by active link mechanism, can avoid in order to guarantee to press-fit coaxial precision carrying out complicated work with axial adjustment to press-fiting body and forcing press, makes device have more versatility, it is also more convenient to use, and is convenient to use under batch working condition.In addition, this device press-fits operation to be simplified, and labour intensity reduces, and press-fits precision and efficient and improves.
