Abstract
The invention relates to a hydraulic machine, in particular to a hydraulic machine provided with a device for carrying out precision machining on a hole through a steel ball. The hydraulic machine comprises an inner hole precision machining device and a hydraulic platform 6. The inner hole precision machining device comprises a hydraulic head 2, a clamp 5 and the steel ball 3. The working surface of the hydraulic platform 6 is provided with the inner hole precision machining device. The clamp 5 is in a hollow U shape so that a workpiece 4 can be placed and the steel ball 3 can be extruded conveniently. The steel ball 3 is placed in an inner hole of the workpiece 4, and is stamped by the hydraulic head 2. The requirement for a cutter and a machine tool of original fine bored holes is replaced, the machining number is two times that of the fine bored holes in unit time, the quality, especially roughness, of machined products is higher than the quality of the fine bored holes, the yield is increased, and production efficiency is improved.
Description
Technical field
The present invention relates to a kind of hydraulic press, more precisely a kind of being equipped with utilized the hydraulic press of steel ball to hole precise machining device.
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 being equipped with to utilize the hydraulic press of steel ball to hole precise machining device.
The present invention adopts following technical measures to realize: a kind of being equipped with utilized the hydraulic press of steel ball to hole precise machining device, and it comprises bore finish machining device and hydraulic pressure platform, and described bore finish machining device comprises fluid head, fixture and steel ball; On the working face of described hydraulic pressure platform, bore finish machining device is housed; Described fixture is hollow concave shape, is conducive to the extruding work with steel ball of putting of workpiece; Described steel ball is placed on the endoporus of workpiece, by fluid head punching press.
Described fluid head is contained in the centre position of hydraulic press, corresponding with bore finish machining device, and punching press end is the circular arc concaving, and matches with the radian of steel ball surface.
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 is that a kind of being equipped with utilized the hydraulic press of steel ball to hole precise machining device, and it comprises bore finish machining device and hydraulic pressure platform 6, and described bore finish machining device comprises fluid head 2, fixture 5 and steel ball 3; On the working face of described hydraulic pressure platform 6, bore finish machining device is housed; Described fixture 5 is hollow concave shape, is conducive to the extruding work with steel ball 3 of putting of workpiece 4; Described steel ball 3 is placed on the endoporus of workpiece 4, by fluid head 2 punching presses.
Described fluid head 2 is contained in the centre position of hydraulic press 1, corresponding with bore finish machining device, and punching press end is the circular arc concaving, and matches with the radian on steel ball 3 surfaces.
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.
