Abstract
The utility model relates to a machine tool appliance, and particularly to a numerically-controlled machine tool fixture. The numerically-controlled machine tool fixture comprises a connection shaft, wherein a sleeve is arranged at the tail end of the connection shaft. The numerically-controlled machine tool fixture is characterized in that an expanded head with an outward opening is fixed in the sleeve, the expanded head, the sleeve and the axis of the connection shaft are superposed, an inclined plane corresponding to the expanded head is arranged in the sleeve, and a plurality of expansion grooves are uniformly arranged outside the sleeve. The numerically-controlled machine tool fixture disclosed by the utility model has the following advantages that: a workpiece is fixed by the sleeve under the expansion force of the expanded head, unable to loosen and displace due to the loosening of clamping, and firmly fixed, and a cutter can freely move outside the workpiece, thus realizing machining on a plurality of end surfaces of a component by one location; and therefore, the high coaxiality of the workpiece during machining is ensured, and the machining quality of the workpiece is guaranteed.
Description
Technical field
The utility model relates to a kind of lathe apparatus, relates in particular to a kind of Digit Control Machine Tool anchor clamps.
Background technology
Digit Control Machine Tool often has part to need two ends turning in processing parts, perhaps on same end and trapezoidal faces, also will carry out repeatedly concentrically ringed turning, and its common point all has higher axiality requirement when being exactly turning.It is fixing that anchor clamps in the time of traditional turning processing generally adopt the mode of three-point fix to be clipped on the part shell part to be advanced, because anchor clamps are to the effects such as obstruction of the cutter of numerically controlled lathe, cutter moves freely at periphery of part; Therefore can not process the part inner side end, must adopt the mode of processing step by step, be i.e. end face of fixing earlier processing; Need part be reorientated fixing then; Reprocess another end face, and adopt the mode of bikini location to be clamped on the shell of part part to be carried out fixing, part also can be owing to reason displacements such as vibrations, anchor clamps are loosening; Thereby no matter be to the turning of part two ends or in the concentric circles turning of same end face both sides; All the coaxial accuracy to part processing produces considerable influence, influences the machining accuracy of part, even part is scrapped.
Therefore, invent a kind of anchor clamps that are not shifted,, do not influence the machining accuracies such as axiality of part, become a kind of problem demanding prompt solution because of vibrations, the loosening perhaps influence of other factors of anchor clamps because of external force.
The utility model content
The utility model proposes a kind of Digit Control Machine Tool anchor clamps, and these Digit Control Machine Tool anchor clamps fix workpiece through outside expansion, can be because of the machining accuracy of vibrations, cause influence workpiece such as loosening, thus axiality is exerted an influence.
The utility model solves the problems of the technologies described above the technical scheme that adopted like following description:
A kind of Digit Control Machine Tool anchor clamps; Comprise connecting axle; The connecting axle end is provided with sleeve, it is characterized in that: be fixed with the outside expansion head of opening in the described sleeve, expand head, sleeve and connecting axle axis coinciding; Sleeve inner is provided with the inclined-plane corresponding with expanding head, and the sleeve outside evenly is provided with some expansion grooves.
Further, preferred scheme is: pass through bolt between described sleeve and the expansion head.
The beneficial effect of the utility model is: sleeve is fixed workpiece under the expansionary force that expands head, can not become flexible; Can be because of the clamping loose shift yet; Fixation, cutter can be in the outer workpiece freely-movables, thereby realize that one-time positioning can process at a plurality of end faces of part; Thereby guaranteed that workpiece adds and has higher axiality man-hour, guarantees the workpiece processing quality.
Description of drawings
Through the description of its exemplary embodiment being carried out below in conjunction with accompanying drawing, the above-mentioned feature and advantage of the present invention will become apparent and understand easily.
Fig. 1 is the structural representation of the utility model Digit Control Machine Tool anchor clamps;
Among the figure, 1 connecting axle, 2 sleeves, 3 expand head, 4 workpiece.
Specific embodiment
Below in conjunction with accompanying drawing the utility model is carried out detailed description.
Fig. 1 is the structural representation of the utility model Digit Control Machine Tool anchor clamps;
As shown in the figure, this device comprises wherein, connecting axle 1, and sleeve 2 expands 3, workpiece 4.
In the utility model, connecting axle 1 end is provided with sleeve 2, is fixed with the outside expansion of opening 3 in the sleeve 2, expands 3, sleeve 2 and connecting axle 1 axis coinciding, and sleeve 2 set inside have and expand a corresponding inclined-plane, and sleeve 2 outsides evenly are provided with some expansion grooves.Sleeve 2 and expand 3 between pass through bolt.
Sleeve 2 expands in truncated cone-shaped under 3 the expansionary force, and workpiece 4 is fixing, can not become flexible; Can be because of the clamping loose shift yet; Fixation, cutter can move at workpiece 4 external freedoms, thus the realization one-time positioning can be processed at a plurality of end faces of part; Thereby guaranteed that workpiece 4 adds and has higher axiality man-hour, guarantees the workpiece processing quality.
It should be noted that; Above-mentioned specific embodiment is exemplary; Under the above-mentioned instruction of the utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improve or distortion drops in the protection domain of the utility model.
It will be understood by those skilled in the art that top specific descriptions just in order to explain the purpose of the utility model, are not to be used to limit the utility model.The protection domain of the utility model is limited claim and equivalent thereof.
