This process is equivalent to mounting the guiding device on the bar, i.e. aligning the central axes of the cutter body 4 and the bar, and then turning the first connecting piece 2 into the clamping groove of the lathe tool rest 1 for fastening. Compared with the method that the first connecting piece 2 is installed on the lathe tool rest 1, the subsequent work of adjusting the coaxiality of the cutter body 4 and the bar by adjusting the lathe tool rest 1 is avoided, and the installation mode is simplified.
Bar limiting plate 5 is the strip shaped plate that the through-hole was seted up at both ends, bar limiting plate 5 is on a parallel with first connecting piece 2, also be on a parallel with the rotation face of first connecting piece 2 and second connecting piece 3, all set up the screw on first connecting piece 2 and the second connecting piece 3, when the contained angle of first connecting piece 2 and second connecting piece 3 is 180, the position of screw and through-hole corresponds, bar limiting plate 5 passes the through-hole screw thread through the bolt and installs in the screw, thereby connect first connecting piece 2 and second connecting piece 3, the limiting displacement is played. When the first connecting piece 2 needs to be rotated, any bolt is disassembled, so that the aim of rotating the first connecting piece 2 can be fulfilled.
The blind hole center pin also sets up along the radial of ring 6, and universal ball 9 includes the shaft and inlays the ball at the shaft internal rotation, and the shaft external diameter is less than the blind hole internal diameter, and the hole bottom of spring one end rigid coupling blind hole, the one end that the other end rigid coupling shaft stretched into the blind hole. When the universal ball 9 withstands the bar, elastic deformation can take place for the spring, makes the universal ball 9 take place elastic displacement in the small-scale within range, can prevent the position of the dead bar of universal ball 9 lock to make the bar normally rotate in ring 6 under the support of universal ball 9.
Through installing simultaneously on lathe tool rest 1 the utility model discloses a cover sword with cut off lathe tool 10, utilize the cover sword to bore the hole back on the bar, withdraw from cover sword and rotate lathe tool rest 1 again and carry out the tool changing operation, then can utilize and cut off lathe tool 10 and cut off the gasket from the bar, need not the position of change bar, improved the work efficiency of car gasket.
As an optimized scheme, one end of the screw rod 8, which is positioned outside the circular ring 6, is fixedly connected with a handle. The screw rod 8 can be directly rotated through the handle without the help of tools, so that the operation of a worker is more convenient.
Preferably, the inner wall of the sleeve 42 is provided with a spiral groove. After the cutter body 4 drills into the bar core, the generated metal chips are discharged outwards along the gap between the inner side and the outer side of the sleeve 42 and the bar, and the metal chips can be discharged outwards along the spiral groove by arranging the spiral groove, so that the chip removal of the cutter body 4 is smoother.
When using, will thick bar clamping earlier on turning attachment, then overlap the tip at the bar with ring 6, the length of bracing piece 7 is greater than sleeve 42's length, consequently when ring 6 overlaps at the bar tip, can push up tool bit 43 on the bar terminal surface, adjust sleeve 42 to coaxial with the bar, screw up lead screw 8 in proper order, lead screw 8 drives universal ball 9 and pushes up on the bar to can install ring 6 on the bar. Because the circular ring 6 is fixedly connected with the second connecting piece 3 through the support rod 7, and the cutter body 4 is also arranged on the second connecting piece 3, the cutter body 4 and the bar stock can be coaxial by fastening the circular ring 6 and the bar stock coaxially. When the ring 6 is installed, the first connecting piece 2 and the second connecting piece 3 are in a vertical state, and a screw is not installed on the strip-shaped limiting plate 5. Therefore, when the ring 6 is installed, the connection between the first connecting piece 2 and the lathe tool rest 1 does not need to be considered temporarily, after the ring 6 is installed, namely after the center shafts of the bar and the cutter body 4 are aligned, the lathe tool rest 1 is moved to a proper position close to the first connecting piece 2, the first connecting piece 2 is turned over again to form an included angle of 180 degrees with the second connecting piece 3, and then the bolt lacking in the strip-shaped limiting plate 5 is installed, so that the first connecting piece 2 and the second connecting piece 3 can be locked. When the first connecting piece 2 is turned over, the first connecting piece 2 can be directly turned into the clamping groove of the lathe tool rest 1, and then the first connecting piece 2 is locked on the lathe tool rest 1 according to a method for installing a traditional lathe tool.
Start the lathe, turning attachment drives the bar and rotates, the utility model discloses a box knife is motionless, therefore the bar can be at 6 internal rotations of ring under universal ball 9's support. Because the bar is in unsettled state at the one end of keeping away from the turning attachment when rotating, the position of bar is injectd through lead screw 8 and corresponding universal ball 9 to ring 6 to can prevent that the bar from taking place the skew at the rotation in-process. Then, by controlling the tool rest 1 to feed only along the axial direction of the bar, the tool bit 43 can cut at the core of the bar, so that the sleeve 42 can be drilled into the core of the bar, the drilled metal chips can be discharged outwards along the gap between the inner side and the outer side of the sleeve 42 and the bar, and then the metal chips are discharged out of the sleeve 42 through the chip removal hole.
When the depth is reached, the cutter body 4 is withdrawn, the circular ring 6 is withdrawn from the bar stock, and then the lathe tool rest 1 is rotated to change the tool into a cutting lathe tool 10 to cut off the gasket from the hollow bar stock according to the traditional cutting mode.
The utility model discloses mainly used copper or other precious metals can take out a thinner bar core at thick bar core cover, has reduced the waste of resource, utilizes the bar core that the cover was taken out to can be used for the manufacturing of other suitable parts, can produce the product except that the gasket through utilizing a bar promptly, consequently can improve the utilization ratio of bar, is favorable to reduction in production cost. And the utility model discloses a set sword can the direct mount on the knife rest of traditional lathe, and the knife rest of traditional lathe is the rectangle, can be in four lathe tools of direction installation, consequently through the handle the utility model discloses a set sword with cut off the lathe tool and install simultaneously on the knife rest, can utilize same equipment just can realize drilling and cutting function, only need through the swivel tool rest tool changing can, need not to take off the bar that has bored the hole and change equipment, simplified the manufacture process of gasket, improved the work efficiency of car gasket, reduced staff's intensity of labour.
