Yet, because part to be processed belongs to thin and long shafts part, it is completely in vacant state to add man-hour, its discontinuity, adds the poor rigidity of part own, when carrying out the machinings such as turning, grinding, milling, gear hobbing, easily there is the problems such as bending, tapering, dolioform and vibration, the element precision processing does not reach the requirement of regulation, and flank of tooth surface roughness is poor, has the spot of shaking phenomenon; And adopt this fixture, clamping parts be inconvenient, debug time is long, working (machining) efficiency is low.
Summary of the invention
In order to overcome the defect existing in prior art, the utility model object is to provide a kind of convenient mounting and clamping, working (machining) efficiency is high, stressed evenly, precision is high, without the slender axles termination gear-hobbing clamp of the spot phenomenon of shaking.
To achieve these goals, the utility model is by the following technical solutions:
The utility model provides a kind of slender axles termination gear-hobbing clamp, comprise lathe base, also comprise that its centre is provided with top adpting flange and base, described base, adpting flange tightens together with hexagon nut with flange, taper copper collet is installed in the taper hole of described base upper end, copper collet is outside equipped with clamp nut, both sides, adpting flange center, with bolt, base and adpting flange are fastenedly connected, the two ends of adpting flange are provided with T-shaped groove, by T-shaped groove, with nut and T-shaped groove, with bolt, adpting flange is fastened on platen.
The top axiality ψ of top and lathe on described adpting flange is: ψ≤0.01mm.
Top axiality ψ on the described base upper end tapered hole conical surface and adpting flange is: ψ≤0.01mm.
Described base upper end bellmouth length L is: 80mm≤L≤130mm.
Described hexagon nut with flange inner side is provided with packing ring.
The inner side of described bolt is provided with plain washer.
The inner side of described nut is provided with plain washer.
Compared with prior art, the utlity model has following advantage:
Handling part very convenient, when processing parts, stressed section copper collet and lathe top between, shortened so the stressed distance of part, strengthened the rigidity of part in process, it is stressed evenly, the element precision that processes is high, without shaking spot phenomenon, thereby improved working (machining) efficiency.
2. according to the clamping diameter of part, can realize by changing the copper collet of corresponding internal diameter the processing of part, according to the size of the length of part and gear hobbing helical angle, can realize by changing the height of base the processing of part, thereby realize the versatility of fixture, reduced the input of production cost.
3. this fixture is highly suitable for processing slim axle gear hobbing gear.
