The working process is as follows: the worker clamps the gearbox shell by the three-jaw chuck 4, then transversely pushes the inner environment of the lathe cabin door 5 to seal the working environment and simultaneously lights the inner lamp tube 3, then programs and controls the mechanical transmission case 6 by the man-machine interface screen 1 to call the double-column end tool apron 2 to perform coordinate cutting processing on the base bottom plate 7, so that the side thin blade 2A1 of the claw-knife rotating cylinder 2A is unfolded in the rotation of the clamping cylinder 2A2 and the inclined knife-line cylinder 2A3 engaged threaded rod 2A4, the side knife-board 2A11 and the knife-edge hard piece 2A13 form a fifteen-degree inner-angle rotating deep-drilling planing cutting inner diameter groove, then pulls the conveyor belt 2H to rub the spherical shaft ring 2F in the rotating bottom plate groove block 2G, the spherical shaft ring 2F is pulled to clasp the side rotating board 2E in the convex-column end groove cylinder 2D to rotate, so that the sleeve clasp the inserting side rotating board 2E1 and the torque of the fine wire rod 2E3 synchronously screw thread 2A to push the threaded rod 829, the linear velocity and the angular velocity are enabled to work synchronously in a double-hole mode all the time, then the solid balancing weight 2E24 is lifted in the side frame plate groove 2E21 through the clamping collar 2E22 and the ear plate seat 2E23 to rotate eccentrically around the thin screw rod 2E3, the pressure-isolating stable knife edge surface of the amplitude is conveniently pushed to the cutting chamfer by matching the inclined plane knife plate 2C, the careful operation of cylinder opening processing is guaranteed, then the pin rotating wheel plate 2B1 of the vibration pad overturning rod 2B is matched with the traction friction of the conveyor belt 2H, the fin column block 2B11 and the pressing convex angle pipe 2B13 in the hook cover plate 2B12 push the transverse pipe spherical shell 2B14 to rotate up and down, the friction speed reduction and vibration isolation effect is guaranteed, the swinging of the bottom plate groove block 2G against the gearbox shell is facilitated to form a shearing force matching effect, the rubber piston rod 2B3 spirally pushes the spring wire groove barrel 2B2 to reciprocate, the spring wire valve core 2B44 of the vibration pad valve ball 2B4 is driven to pull the tightening and overturning cloth groove, the spring wire valve core 2B44 is enabled to form a traction corrugated valve belt 2B42 in the ellipsoidal shell 2B43 and the colloid arc pad 2B45 to indicate the load degree, the vibration isolation bearing capacity of the shell and the critical value regulation and control effect of cutter maintenance are guaranteed, the cutter is guaranteed to be resistant to breakage, the cylinder groove and the cylinder opening of the cylinder cover of the gearbox are accurately and quickly processed, and the assembly work of the high-quality embedded vehicle body piston is achieved.

The invention achieves the purposes that the double-column-end tool apron 2 is matched with the three-jaw chuck 4, the gearbox shell and the cylinder cover are clamped by the three-jaw chuck 4, the claw-knife rotary drum 2A in the convex-column-end grooved drum 2D and the inclined-plane knife plate 2C are used for deeply planing the cylinder grooved drum in steps and different positions in sequence to form the double-drilling processing effect of the side thin blade 2A1 and the inclined-plane knife plate 2C, the cylinder mouth chamfer threads are sequentially trimmed in the first step of deep-grooving of the gearbox cylinder cover and the second step of deep-grooving, the embedding degree of the cylinder cover is high, the bottom plate grooved block 2G is abutted against the three-jaw chuck 4 and is positioned on the gearbox shell, the same frequency effects of measuring distance and drawing amplitude are formed by the shock pad overturning rod 2B, the rotation deviation amplitude is consistent, the large-amplitude deviation of the width is directly reduced, the synchronous deviation directly eliminates interference factors, and the angular speed and the processing and the propulsion effect of the same-amplitude, the stability of guarantee frame and the internal heat value coefficient of gearbox cylinder cap butt joint automobile body motor piston reach standard to this solves gearbox numerical control lathe processing and is the deep-cut laminating cylinder cap screw thread butt joint that needs the jar mouth of having more, this makes the knife rest offset on the lathe can not shake too big, but the gearbox casing self weight height of three-jaw chuck clip, gyration centrifugation range of rocking is big, the horizontal feed gyration volume of knife rest is bigger than conventional cutting gyration circle footpath when making the cutting feed, lead to the wide grow in the jar mouth degree of depth, influence the friction coefficient and the internal heat value of piston rod butt joint in the piston cylinder, when causing the gearbox after the processing to install at the automobile body, the condition of skidding of piston motion increases, reciprocal driving force reduces, lubricating oil consumption is too big, cause serious size deviation's problem for the cylinder cap deep troughhole.
