Description

Numerically controlled lathe special-shaped workpiece aids in clamping device
Technical field
The utility model belongs to numerical controlled machinery instrument, more particularly to a kind of numerically controlled lathe special-shaped workpiece auxiliary clamping device.
Background technology
Numerically controlled lathe is at present using one of relatively broad numerically-controlled machine tool, it is mainly used for axial workpiece or disk-like accessory Inside and outside cylindrical surface, the inside and outside circular conical surface of arbitrary cone angle, the machinings such as positive camber and cylinder, tapered tread in complicated revolution, And grooving, drilling, reaming, fraising and bore hole etc. can be carried out.When processing the workpiece, clamping workpiece often uses three-jaw to numerically controlled lathe Chuck etc., scroll chuck is moving radially using three movable jaws being distributed on chuck body, Workpiece clamping and positioning. For the part of mass production, the automation of production process can have been realized using automated and semi-automatic lathe, still, It is existing especially in the part that machining shape is complicated, requirement on machining accuracy is high for the part of single-piece, small lot production Chuck is difficult to accomplish quick and precisely centering.Existing scroll chuck is in processing profiled workpiece, it is necessary to especially be surveyed using dial gauge It measures and increases auxiliary spacer to carry out centering, it is exactly that can use floral disc to also have a kind of mode, but since floral disc workpiece is more multiple It is miscellaneous, it is loaded more difficult, so the time of centering also can be long, again such that the efficiency of chuck positioning processing is equally very low.
Utility model content
The utility model overcomes chuck clamping in the prior art for problem present in digital control lathe chuck clamping workpiece The problem of special-shaped workpiece is more difficult, and the time of centering can be long provides a kind of rational in infrastructure, convenient disassembly, precision machining Spend high numerically controlled lathe special-shaped workpiece auxiliary clamping device.
The utility model is by solving the problems, such as above-mentioned adopt the technical scheme that:Numerically controlled lathe special-shaped workpiece aids in Clamping device including chuck and the retaining sleeve being arranged on chuck and clamping core, is provided with several on the claw of the chuck The step that reduces successively of height from outside to inside is both provided with the encapsulation of fixed clamp set on the step of the claw and on retaining sleeve Hole, is provided with the mounting surface less than retaining sleeve height on the inside of the retaining sleeve, symmetrical on the end face of mounting surface and on clamping core The cored hole of fixed clamp core is provided with, the inner surface of the clamping core forms piece-holder chamber.
Further, the piece-holder chamber is ellipse or polygon.
The beneficial effects of the utility model are:Compared with prior art, 1, by setting retaining sleeve and clamping core this reality It need not repeat centering when processing the workpiece with new, can centering be automatically positioned according to the shape of special-shaped workpiece, significantly Positioning auxiliary time during processing is shortened, reduces error during clamping, improves machining accuracy and the work of special-shaped workpiece Efficiency is the processing that more than three times of existing processing and positioning device can be widely used for large batch of special-shaped workpiece;2nd, retaining sleeve and Core quick release is clamped, it can be according to the replaceable different clamping core of needs of product.

Fig. 2 is the dimensional structure diagram of the utility model,
Fig. 3 is the fractionation structural representation of the utility model,
Fig. 4 is another main structure diagram of the utility model.
In the figure 1, retaining sleeve 2, claw 3, clamping core 4, chuck 5, piece-holder chamber 6, step 7, mounting surface 8th, cored hole 9, encapsulation hole.
Specific embodiment
In order to enable those skilled in the art to better understand the technical solutions of the present invention, below in conjunction with the accompanying drawings to this reality With new further explanation.
As shown in Figure 1, 2, 3, the numerically controlled lathe special-shaped workpiece auxiliary clamping device, including chuck and is arranged on chuck Retaining sleeve 1 and clamping core 3 on 4(Claw, retaining sleeve, clamping core in figure are divided into three pieces), set on the claw 2 of the chuck It is equipped with several steps 6 for reducing successively of height from outside to inside, geometrical clamp is both provided on the step of the claw and on retaining sleeve It holds the encapsulation hole 9 of set, is provided with the mounting surface 7 less than retaining sleeve height on the inside of the retaining sleeve, on the end face of mounting surface and press from both sides The cored hole 8 that fixed clamp core is symmetrically arranged on core is held, the inner surface of the clamping core forms piece-holder chamber 5(In Fig. 1 For ellipse), it is above-mentioned in each piece clamping core not necessarily same shape, it is necessary to according to the shape of workpiece in advance carry out in The various forms of processing in surface, are then combined into piece-holder chamber, and the encapsulation hole and cored hole are connected by screw bolts.
Therefore, the shape of the piece-holder chamber is except ellipse, can also as described in Figure 4 or pentagon or The other arbitrary shapes of person are, it is necessary to process the shape of clamping core according to the shape of special-shaped workpiece.
During processing, after auxiliary clamping tool combinations, the shape of piece-holder chamber is exactly the shape of special-shaped workpiece, processing clamping To ensure that the centre of gyration of special-shaped workpiece is overlapped with clamping the center of circle of core during core, it is different when claw, retaining sleeve, clamping core are closed The holding chamber of shape workpiece auxiliary clamping device is adapted with the clamping face for the special-shaped workpiece that needs are processed.Special-shaped workpiece auxiliary clamping The retaining sleeve of instrument, three claws clamped on core, holding chamber and chuck are connected to become an entirety respectively, when claw moves It can be synchronized with the movement with claw, reach self centering effect.When processing the workpiece, special-shaped workpiece retaining sleeve is installed to three-jaw certainly On the claw of centering chuck, clamping core is fixed by bolts on retaining sleeve, then clamping workpiece into holding chamber, is then used Chuck clamps, and such workpiece is with regard to that can be automatically positioned centering.
Embodiment of above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although with reference to specific embodiment The utility model is described in detail, it will be understood by those of ordinary skill in the art that, it can be to the skill of the utility model Art scheme is modified or replaced equivalently, and without departing from the spirit and scope of technical solutions of the utility model, should all be covered In the protective scope of the claims of the utility model.
