Abstract

The invention discloses an expanding gear hobbing mould which comprises a base. A support table which is used for supporting and positioning a to-be-processed gear ring is arranged on the base; the support table is provided with an inner chamber; ring-shaped tensioning arms which can laterally expand outwards from the center of the inner chamber are arranged in the inner chamber; the external side faces of the ring-shaped tensioning arms are in expanding connection with the inner side face of the to-be-processed gear ring; a hydraulic system which is used for driving the ring-shaped tensioning arms to move is arranged in the inner chamber; and the hydraulic system comprises a hydrocylinder which is fixed at the bottom of the support table and a piston rod which is respectively connected with the external side faces of the ring-shaped tensioning arms at two sides of the hydrocylinder. The expanding gear hobbing mould effectively solves the problem that as fixing nuts need to be unscrewed every time gear rings of a gear hobbing machine are assembled and disassembled in the current processing of gear rings, the time and the labor are wasted and the processing quality of the gear rings is affected because of the inconsistency in the tightness degree of fixing nuts due to the adoption of manual operation. The expanding gear hobbing mould has the advantages of simplicity in structure and high efficiency in gear hobbing.

In today that the Automation in Mechanical Working degree improves day by day, carry out in the Gear Production process in enormous quantities, how when improving machining accuracy, to reduce the clamping workpiece time, be the problem that presses for solution.Flywheel ring gear is anchored on the flywheel outer rim after the cooling through being set on the flywheel outer rim after the heating, is used for and the starter gear engagement, drives crankshaft rotating, pilots engine.---the detection of blank---modifier treatment---machined into---gear hobbing---boring---Quenching Treatment---flaw detection---high tempering---detection---packing that the processing technology of gear ring generally comprises following steps: blank forging.
CN202367295U discloses a kind of centering gear hobbing anchor clamps for inside spline wheel gear.A kind of centering gear hobbing anchor clamps, the clamping element that comprises base, mandrel and be located at the cushion cover on the mandrel, elastic corrugated cover, compressing member, gland and be used for adjusting gland and cushion cover spacing; The mandrel bottom is installed on the base, cushion cover is installed on the base by mandrel and is set in the bottom of mandrel, elastic corrugated cover is fixed on the mandrel middle part, the position is between cushion cover and the gland, and the diameter of elastic corrugated cover is less than the cushion cover of its below and the gland of top, gland is set in mandrel top, and gland is corresponding with the cushion cover of its below, and the clamping element that is used for adjustment gland and cushion cover spacing is in the gland top; Compressing member is located on the mandrel between elastic corrugated cover and the gland.
Above-mentioned gear ring stationary fixture adopts gear ring is enclosed within on the mandrel then with the fixing mode of hold-down nut, though can guarantee that follow-up gear hobbing is more stable, makes gear hobbing precision height, and gear hobbing is effective.All must turn on hold-down nut but this frame mode loads and unloads gear ring at every turn, not only waste time and energy, and owing to be manually-operated, the elasticity of each hold-down nut is inconsistent, has influenced the quality of gear ring.
CN201089048Y discloses a kind of gear-hobbing machine hydraulically operated fixture, the gear-hobbing machine hydraulically operated fixture comprises base, bearing, piston, mandrel and hydraulic circuit, be provided with bearing above the base, the centre is provided with oil cylinder, the bottom of base is provided with and connects dish, and piston is arranged in the oil cylinder, connects mandrel on the piston, mandrel is upward through bearing, and the top of mandrel is provided with fixture.It has solved present gear-hobbing machine effectively and has loaded and unloaded gear at every turn and all must turn on hold-down nut, not only waste time and energy, and the elasticity of each hold-down nut is inconsistent under the manually-operated, influences the problem of the quality of gear.
Though it is simple in structure that above-mentioned utility model has, gear is easy to loading and unloading, and crudy is good, the advantage that gear hobbing efficient is high.But the hydraulic drive mechanism of this hydraulic pressure gear hobbing frock is located at frock inside, offers the endoporus as oil cylinder in binding site inside such as the base of frock and bearings.
Summary of the invention
At the deficiency that prior art exists, technical problem to be solved by this invention is, provide a kind of accurate positioning, dismounting easy, effectively guarantee gear hobbing precision and working (machining) efficiency and improve the expanding-contracting type gear hobbing mold in service life.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of expanding-contracting type gear hobbing mold, comprise base, be provided with one at base and be used for supporting the brace table of locating gear ring to be processed, described brace table has an inner chamber, being provided with in this inner chamber can be from the annular means for belt tension of the outside lateral magnification of described lumen centers, annular means for belt tension lateral surface is connected with the medial surface tensioner of described gear ring to be processed, be provided with the hydraulic system that drives annular means for belt tension motion in inner chamber, described hydraulic system is formed by being fixed on the hydraulic jack of supporting the platform bottom and the piston rod that links to each other with the annular means for belt tension medial surface of hydraulic jack both sides respectively.
Above-mentioned expanding-contracting type gear hobbing mold, described annular means for belt tension top are provided with the detent mechanism for vertically fixing gear ring to be processed.
Above-mentioned expanding-contracting type gear hobbing mold, described detent mechanism by self-supporting platform bottom extend upward setting backstay, pass that backstay acts on the location gland on the gear ring to be processed and the clamp nut that is connected with the backstay screw top be located on the gland of location is formed.
Above-mentioned expanding-contracting type gear hobbing mold, the bottom of described annular means for belt tension and brace table bottom are connected by track-type facilities.
Above-mentioned expanding-contracting type gear hobbing mold, described location gland is provided with easy-to-dismount suspension ring.
The advantage of expanding-contracting type gear hobbing mold of the present invention is: be used for the gear ring gear hobbing and add man-hour, clamping for gear ring in enormous quantities, do not need to use the spanner tighten the screws in the clamping process, time saving and energy saving, efficiently solving in the processing of present gear ring gear-hobbing machine loads and unloads gear ring at every turn and all must turn on hold-down nut, not only waste time and energy, and the elasticity of each hold-down nut is inconsistent under the manually-operated, influence the problem of gear ring crudy, and hydraulic power is arranged on outside the mold, avoided traditional tensioner frock to leak because of flexible wearing and tearing build-up of pressure repeatedly, influence expanding force, cause the generation of problem such as machining accuracy reduction, and the workpiece that processes can take out directly, realized the location, no gap of anchor clamps and workpiece endoporus, positioning accuracy is good, the location is rapid, and the present invention is simple in structure, gear hobbing efficient height.
