Prior art: existing a kind of stereo-profile-tracing turning apparatus that engine piston skirt profile profile is shaped and processes that is used for, pendular body is fixed on two ends respectively to be had on the swinging axle of a centre bore, pendular body and swinging axle and along the T type groove on the pendular body (with the lathe parallel longitudinal) the adjustable tool rest in position, profiling refers to seat, push type broach (comprising that profiling refers to) screw, T type groove nut and joint bolt thereof constitute the moving tilting member of tail spindle string pendulum that withstands in the centre bore of swinging axle two ends on base, between the fork of a side on the pendular body and base, supporting garden column type spiral compression spring, imitative type refers under the spring force effect, be pressed on the pattern working surface, whole device is installed in the horizontal slide carriage of horizontal precise hydraulic semi-automatic lathe top by its base, regulate horizontal slide carriage position and tool rest, profiling refers to seat relative position in T type groove, and it is horizontal to finish engine piston in the certain specification size range, the engine piston skirt profile profile contour turning that longitudinal type line is combined into.But because tilting member is big around top axis rotary inertia, causes cutting linear velocity lower, and, obtains higher relatively cutting linear velocity, lathe tool is not set, the type of imitating refers to the lateral attitude governor motion in order not increase tilting member around top axis rotary inertia.

The purpose of this utility model: the purpose of this utility model is to provide a kind of being used for to have the high performance of cutting linear velocity and lathe tool, profiling and refer to the function that the lateral attitude is adjustable along the stereo-profile-tracing turning apparatus of the rotation positive camber shaping processing of circumferential and axial radius trace variation.

Technology contents of the present utility model: the utility model is a kind of being used for along the stereo-profile-tracing turning apparatus of the rotation positive camber shaping processing of circumferential and axial radius trace variation, be installed on horizontal precise hydraulic semi-automatic lathe or the horizontal slide carriage of precision geared head lathe, two top withstanding in the centre bore of T type groove seat two ends on the base, T type groove seat and fork tighten together with screw and constitute aforesaid pendular body (both can make an integral body), pendular body and be connected in the adjustable lathe tool of T type groove seat upper edge lathe lengthwise position, profiling refers to, the push type broach screw, T type groove nut and joint bolt thereof, constitute tilting member, profiling in the tilting member refers under the spring assembly effect that is bearing between base and the fork, be pressed on the pattern working surface, unload the detachable lathe tool, profiling refers to the lateral attitude governor motion, after starting lathe, along with pattern, workpiece to be machined and lathe spindle, the coaxial synchronous rotation of tailstock center and vertically moving of lathe saddle, lathe tool in the tilting member, its point of a knife are promptly done along lathe vertical, the contour turning of horizontal combinations of directions

Below in conjunction with accompanying drawing the utility model is described in further detail.

Accompanying drawing 1, a kind of concrete structure schematic front view of the present utility model.

The concrete structure vertical view of accompanying drawing 2, accompanying drawing 1 expression.Wherein removed the detachable lathe tool, profiling refers to the lateral attitude governor motion.

Accompanying drawing 3, along the partial sectional view of I in the accompanying drawing 2-I line, show detachable lathe tool, profiling and refer to that the lateral attitude governor motion constitutes.

With reference to accompanying drawing, base 1 is screwed on the horizontal slide carriage of horizontal lathe, top 4 screw in the nut 6 that is screwed on the supporting base of base 1, locking nut 5 is used for fixing top 4 position, on top 7 other end supporting bases (two supports seat and base can respectively make separating member) that are screwed at base.

Tool rest, profiling refer to that seat respectively is connected on the T type groove seat 3 by T type groove nut and screw (not drawing among the figure), and tool rest, profiling refer to that feather key (not drawing among the figure) is all arranged at the seat bottom.

Fork 2 one ends are fixed on the T type groove seat with screw 10, and in the keyway on anti-rotation flat key (not drawing among the figure) the embedding T type groove seat on the fork, they constitute pendular body (also can make integral body) together, make to have mounting hole on the fork.

Spiral supporting

plug

12,13 screws in spring 11 two ends respectively, spring adjustment plug 16 screws in guard shield 17, these constitute spring assembly with nut 18, the turn guard shield, locking nut 18 promptly changes the setting height(from bottom) of spring assembly on base, the spiral supporting plug respectively with fork and spring adjustment plug opposite face on centre bore float by

garden ball

14,15 and connect, the garden ball material is that coefficient of friction is little, the plastics of good rigidly or steel.Under spring action, imitative type finger pressure is on pattern 37 surfaces.

Have wear-resistant; impact-resistant titanium carbide coating carbide-tipped lathe tool 20 is stuck in the spring leaf cutter holder 21, and pressure knife block 22 tool settings of cutter holder top pick up protective effect, select the knife pading block 23 of different-thickness; pressure knife block changes height along screw 36 thereupon, thereby satisfies different heighknife holder height requirements.

One end of regulating shaft 26 screws in the spring leaf cutter holder afterbody screw, adjustment seat 24 usefulness screws 25 are clamped on the tool rest, garden column type spiral compression spring 27, collar 32 is between adjustment seat and cutter holder, the rotation regulating shaft is promptly realized not having gap adjusting graduated ring 28 and is indicated regulated quantity, the graduated ring that cushion (as spring leaf, rubber blanket) 29 and housing screw 30 can make sky be enclosed within on the regulating shaft pins at any circumferential position, screw 31 can screw out regulating shaft after compressing lathe tool from cutter holder, unclamp screw 25 and can unload the detachable adjusting device.

The profiling of being made by phenolic aldehyde (lamination fabric swatch) plastics or soluble polyimide plastics refers to also have above-mentioned adjusting device.

After unloading the detachable adjusting device, start lathe, pattern 37, workpiece to be machined 33 and lathe spindle 34, tailstock center 35 coaxial, synchronous rotations, truning fixture vertically moves with the lathe saddle simultaneously, and lathe tool promptly carries out contour turning to workpiece to be machined.
