Abstract
The utility model relates to a symmetric linear cutting machining clamp for a cylindrical workpiece. The symmetric linear cutting machining clamp comprises a cushion block, a V-shaped groove is formed in the middle of the cushion block, a cylindrical sleeve barrel is arranged in the V-shaped groove of the cushion block, the front end of the sleeve barrel stretches out of the V-shaped groove, step holes coaxial with the sleeve barrel are formed in the sleeve barrel, the step holes comprise a large hole formed in the front portion of the sleeve barrel and a small hole formed in the rear portion of the sleeve barrel, the inner diameter of the small hole is matched with the outer diameter of the workpiece needing to be machined, and two penetrating holes allowing a molybdenum wire to penetrate are correspondingly formed in the upper hole wall and the lower hole wall of the large hole. A locating hole used for allowing a locating bolt to be mounted is formed in the hole wall of the small hole. The penetrating holes are square, and the two penetrating holes are formed symmetrically. The symmetric linear cutting machining clamp is simple in structure and firm in clamping, and the workpiece machining symmetry degree is high after the workpiece is clamped.
Description
Technical field
The utility model relates to linear cutting clamp field, specifically cylindrical workpiece line of symmetry cutting processing fixture.
Background technology
In production, often to carry out line of symmetry cutting processing to cylindrical workpiece, such as going out two symmetrical tangent planes or grooving etc. in the columned workpiece front cutting such as boring cutter bar, drift.In order to guarantee the symmetry of workpiece processing, utilize at present vee-block to carry out clamping location to workpiece, take drift as example, drift comprises that columniform plunger rod and drift cap and both fix as one, drift is placed in the V-shaped groove of vee-block, utilize pressing plate on wire cutting machine etc. that drift cap is compressed, again the front end of plunger rod is carried out to line of symmetry cutting processing afterwards.Although existing V-block clamping has self-centering function, but for example, for the too short clamping precision that makes of the fixed position due to workpiece (the drift cap of drift) inaccurate, also there will be the unstable phenomenon of clamping simultaneously, thereby can have influence on machining accuracy, be difficult to reach the requirement of symmetry.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, easy to use, clamping firmly and the cylindrical workpiece line of symmetry cutting processing fixture of registration.
For solving the problems of the technologies described above, in the middle of comprising, offers cylindrical workpiece line of symmetry cutting processing fixture of the present utility model the cushion block of V-shaped groove, its design feature is, in the V-shaped groove of described cushion block, cylindrical sleeve is installed, the front end of sleeve leans out and in V-shaped groove and sleeve, offers the shoulder hole coaxial with it, shoulder hole comprises the aperture that is positioned at anterior macropore and is positioned at rear portion, hole diameter coordinates with needing the external diameter of processing work, and on the top hole wall of macropore and bottom hole wall, correspondence offers two mounting holes that pass for molybdenum filament.
On the hole wall of described aperture, offer for the locating hole of bolt is installed.
Described mounting hole is that square opening and two mounting holes are symmetrical arranged.
Adopt said structure, the aperture of shoulder hole coordinates with needing the workpiece plug-in mounting of processing, the front end of workpiece extend in the macropore of shoulder hole, in locating hole, construction bolt positions workpiece, prevent the inaccurate situation in location that not tight causes, reserved mounting hole can be used to install molybdenum filament, and the front end of workpiece is processed.After clamping workpiece, its axis overlaps with sleeve axis, by the external cylindrical surface of sleeve, can determine the position, axis of workpiece, molybdenum filament can produce spark while contacting with sleeve external cylindrical surface, touch spark and can determine origin position, so just can determine the concrete coordinate of processing, after programming, process, the complete like this symmetry requirement that can guarantee Working position.Visible, the utility model is simple in structure, clamping is firm and the symmetry of processing is high.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation before and after the utility model and workpiece processing;
Fig. 2 is that the utility model is along the cutaway view along A-A direction in Fig. 1.
The specific embodiment
With reference to accompanying drawing, in the middle of comprising, offers cylindrical workpiece line of symmetry cutting processing fixture of the present utility model the cushion block 1 of V-shaped groove, cylindrical sleeve 2 is installed in the V-shaped groove of cushion block 1.Wherein, can be by installations such as pressing plates between sleeve 2 and cushion block 1, pressing plate is arranged on the board of wire cutting machine.The front end of sleeve 2 leans out in V-shaped groove and sleeve 2 and offers the shoulder hole coaxial with it 3, shoulder hole 3 comprises the aperture 32 that is positioned at anterior macropore 31 and is positioned at rear portion, aperture 32 internal diameters coordinate with needing the workpiece external diameter of processing, for fixation workpiece, on the hole wall of aperture 32, offer for the locating hole 5 of bolt is installed.On the top hole wall of macropore 31 and bottom hole wall, correspondence offers two mounting holes 4 that pass for molybdenum filament.Wherein, as a kind of preferred version, mounting hole 4 is symmetrical arranged for square opening and two mounting holes 4.
In said structure, need the workpiece of processing to be inserted to the aperture 32 in ladder 3 holes from rear portion, the front end of workpiece extend in the macropore 31 of shoulder hole, at the interior construction bolt of locating hole 5, workpiece is positioned, prevent the inaccurate situation in location that not tight causes, on macropore 31 hole walls, reserved mounting hole 4 is used for installing molybdenum filament.In the past when only using V-block, datum line can only be by calculating, thereby inaccurate, and the symmetry of processed part is undesirable.Used after the utility model, after clamping workpiece, its axis overlaps with sleeve axis, by the external cylindrical surface of sleeve 2, can determine the position, axis of workpiece, molybdenum filament can produce spark while contacting with sleeve 2 external cylindrical surfaces, touches spark and can determine origin position, so just can determine the concrete coordinate of processing, after programming, process the complete like this symmetry requirement that can guarantee Working position.
In sum, the utility model is not limited to the above-mentioned specific embodiment.Those skilled in the art, not departing under the prerequisite of spirit and scope of the present utility model, can do some changes and modification.Protection domain of the present utility model should be as the criterion with claim of the present utility model.
