Description
Technical field
The invention belongs to bar cylindrical parts manufacture field, particularly a kind of with this removable milling attachment with self-centering clamping function as positioning datum of bar cylindrical parts.
Background technology
Carrying out processing to the outer surface of bar cylindrical parts is one of modal processing tasks in industrial circle, is all in most cases to use lathe to carry out turning to complete this processing tasks.Along with the development of industrial technology, equipment and the kind of part become complicated various, and wherein also have a large amount of special equipments and part, this it is also proposed higher requirement to the diversity of process technology.Under the impact of above-mentioned background, lathe turning cannot meet the task of all cylindrical outer surface processing.
Such as: be fixed irremovable bar cylindrical parts, because lathe can not move, so lathe cannot process this kind of bar cylindrical parts; Barrel portion on the parts of complex contour, because lathe is difficult to carry out clamping to this kind of part, so lathe cannot process this kind of part; The bar cylindrical parts that volume is larger, general lathe cannot be processed, if customize special large-scale lathe, then uneconomical.
Comprise the multiple special circumstances of the above three kinds of situation, lathe cannot complete, a kind of device that can meet all kinds of roofbolt shape piece surface processing tasks of present needs, this device also will have higher economy and meet certain requirement on machining accuracy simultaneously.
Summary of the invention
In view of this, for the deficiencies in the prior art and blank, technical problem to be solved by this invention is to provide a kind of milling attachment of self-centering clamping, with processed bar cylindrical parts originally as positioning datum, is realized the surperficial Milling Process of bar cylindrical parts by the rotation of device self structure part.
The present invention to achieve these goals, structure is composed as follows: have hollow channel in the middle of stationary magazine creel (1), described stationary magazine creel (1) is provided with actuating unit (3), clamp system (5), rotating cylinder (2) is provided with delivering gear (7), delivering gear (7) is provided with cutter (8), stationary magazine creel (1) is connected by bearing (6) with rotating cylinder (2), and rotating cylinder (2) is connected by transmission mechanism (4) with actuating unit (3).Centered by the hollow channel of above-mentioned all parts in the middle of stationary magazine creel (1), overall in ring type layout.The axis collinear of stationary magazine creel (1), rotating cylinder (2), bearing (6), described axis is parallel with Y-axis.Delivering gear (7) can control cutter (8), perpendicular to Y-axis, the disc of the center of circle on stationary magazine creel (1) axis diametrically do feed campaign, or delivering gear (7) can control cutter (8) and does feed campaign along Y-axis.
Advantage of the present invention is as follows: delicate structure of the present invention is flexible, there is no pedestal, can move, be applicable to the Milling Process operation of roofbolt shape piece surface, be specially adapted to the bar cylindrical parts that cannot use machine tooling because of not moving, bar cylindrical parts maintains static, and only this device need be enclosed within location clamping on described bar cylindrical parts and just can implement processing operation.The present invention with processed bar cylindrical parts this as positioning datum, self-centering clamping is realized by clamp system (5), make the dead in line of the rotation of principal cutting movement of the present invention and processed bar cylindrical parts, machining accuracy is high, and the dimensional accuracy on the surface (91) of processed mistake is high.

In figure, 1-stationary magazine creel, 2-rotating cylinder, 3-actuating unit, 4-transmission mechanism, 5-clamp system, 6-bearing, 7-delivering gear, 8-cutter, 9-work piece, the surface of 91-processed mistake.
Detailed description of the invention
Exemplary embodiment is as follows: shown in Fig. 3, and work piece (9) maintains static, and the present invention is enclosed within described work piece (9).Start clamp system (5), stationary magazine creel (1) and work piece (9) are fixed together by described clamp system (5).Actuating unit (3) starts, the transmission of torque provided by actuating unit (3) by transmission mechanism (4), to rotating cylinder (2), makes rotating cylinder (2) drive the delivering gear (7) be arranged on rotating cylinder (2) to rotate around work piece (9).In the rotation process of rotating cylinder (2), delivering gear (7) controls cutter (8) and does feed campaign, completes the Milling Process of work piece (9).After processing operation completes, delivering gear (7) withdrawing, actuating unit (3) stops operating, and clamp system (5) stops clamping, finally the present invention is taken off from work piece (9).
Operation principle labor of the present invention is as follows: the present invention's entirety is in ring type layout, and centre has hollow channel that work piece (9) can be made to pass.Clamp system (5) force direction points to the central axis of stationary magazine creel (1), therefore clamp system (5) has the function of self-centering clamping, in the clamp state, the axis of stationary magazine creel (1), rotating cylinder (2), bearing (6) and the dead in line of work piece (9).For above-mentioned reasons, the axis that rotating cylinder (2) is equal to around work piece (9) around own axis rotates, and this ensure that the high accuracy of whole process.Delivering gear (7), cutter (8) are followed rotating cylinder (2) around the axis of work piece (9) and are rotated, the rotary motion of rotating cylinder (2) is the main motion of cutting, delivering gear (7) provides the feed campaign of cutting, cutter (8) perpendicular to Y-axis the disc of the center of circle on stationary magazine creel (1) axis is diametrically moving, cutting depth can be changed, cutter (8) can change length of cut along the movement of Y-axis, and whole working angles is similar to the milling process that workpiece is fixed and cutter rotates.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, obviously, those skilled in the art can carry out various change and distortion to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and distortion belong within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also comprises these changes and distortion.
