Abstract
The invention relates to a device for machining an inner hole, in particular to a device for finish machining of an inner hole by means of a steel ball. The device comprises a hydraulic machine 1, a hydraulic head 2, a fixture 5 and a hydraulic table 6, wherein the hydraulic head 2 is installed in the middle of the hydraulic machine 1; the fixture 5 is installed on a working surface of the hydraulic table 6 and corresponds to the hydraulic head 2; a stamping end of the hydraulic head 2 is an inward concave circular arc and is fit with the surface of the steel ball 3 in radian; the fixture 5 is of a shape like the Chinese character 'ao' hollow in the middle, and facilitates placement of a workpiece 4 and extrusion for the steel ball 3. The requirement of original fine boring for a cutter and a machine tool is replaced, the machining number in unit time is higher than that of fine boring by one time, quality, especially roughness, of a machined product is higher than that of fine boring, and the yield and production benefits are increased.
Description
Technical field
The present invention relates to a kind of inner bore machining device, more precisely a kind of steel ball that utilizes is to the accurately machined device of endoporus.
Background technology
Gear is in machine, to transmit the strength member of motion and power, therefore the precision of gear has determined accuracy and the stationarity of its transmission, because the fine finishining in gear later stage is greatly mainly with Internal hole positioning, the precision of bore processing plays vital effect to the precision of gear.Traditional bore processing all takes scroll chuck to clamp excircle orientation, processing technology by right boring hole guarantees its precision and roughness requirement, batch production should guarantee that by the mode of right boring endoporus precision guarantees roughness again completely, and the efficiency producing in the unit interval is very limited.
Summary of the invention
The object of the invention is to be to overcome above-mentioned weak point, provide a kind of steel ball that utilizes to the accurately machined device of endoporus.
The present invention adopts following technical measures to realize: a kind of steel ball that utilizes is to the accurately machined device of endoporus, and it comprises hydraulic press, fluid head, fixture and hydraulic pressure platform, and fluid head is equipped with in the centre position of described hydraulic press; On the working face of described hydraulic pressure platform, fixture is housed, corresponding with fluid head; The punching press end of described fluid head is the circular arc concaving, and matches with the radian of steel ball surface; Described fixture is hollow concave shape, is conducive to the extruding work with steel ball of putting of workpiece.
Hydralic pressure gauge and motor are equipped with in the inside of described hydraulic pressure platform, are the dynamic Control of fluid head.
The present invention can produce the feature of plastic deformation at normal temperatures under external force by metal, use simple hydraulic single column press that special steel ball is gone out from one end cold extrusion in gear aperture fast, make bore area produce the plastic deformation of moment, thereby reach the object that dilation dimension promotes roughness.
Remarkable result of the present invention: replaced the requirement of original right boring hole to cutter and lathe, processing quantity exceeds one times than right boring hole in the unit interval, and the quality of converted products especially roughness is higher than right boring hole, improved output and increased productivity effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further elaborated.
Accompanying drawing 1 is structural representation of the present invention.
In figure 1, hydraulic press 2, fluid head 3, steel ball 4, workpiece 5, fixture 6, hydraulic pressure platform.
Specific embodiments
As shown in Figure 1, the present invention be a kind of steel ball that utilizes to the accurately machined device of endoporus, it comprises hydraulic press 1, fluid head 2, fixture 5 and hydraulic pressure platform 6, fluid head 2 is equipped with in the centre position of described hydraulic press 1; Fixture 5 is housed on the working face of described hydraulic pressure platform 6, corresponding with fluid head 2; The punching press end of described fluid head 2 is the circular arc concaving, and matches with the radian on steel ball 3 surfaces; Described fixture 5 is hollow concave shape, is conducive to the extruding work with steel ball 3 of putting of workpiece 4.
Hydralic pressure gauge and motor are equipped with in the inside of described hydraulic pressure platform 6, are the dynamic Control of fluid head 2.
During work, by workpiece 4 is lain in special fixture 5, then steel ball 3 is put in the endoporus of workpiece 4, primer fluid press 1 makes fluid head 2 contact steel balls 3 and passes fast the endoporus of workpiece 4, make the endoporus of workpiece 4 produce plastic deformation in moment, thereby reach the requirement of size and the roughness of expection.The enforcement of technique of the present invention, has replaced the requirement of original right boring hole to cutter and lathe, and processing quantity exceeds one times than right boring hole in the unit interval, and the quality of converted products especially roughness is higher than right boring hole, improved output and increased productivity effect.
