Detailed description of the invention
Below in conjunction with accompanying drawing 1-3, a kind of embodiment of the present invention is described.
For the accurately machined follow-rest of slender axles, comprise support 1 that knife rest 9 attached with lathe be connected and adjust stud 2, described support 1 is provided with locating hole 11, described support 1 can manufacture shape as shown in Figure 1, also the shape of support 1 specifically can be determined according to the position of the position on the attached knife rest 9 of lathe and part 7, described adjustment stud 2 is formed primarily of threaded rod 21 and polished rod 22, polished rod 22 one end of described adjustment stud 2 is passed locating hole 11 and is reached outside, support 1 side, concrete, described locating hole 11 is the stepped bores coaxially connected into by screwed hole 111 and unthreaded hole 112, described screwed hole 111 screws with the threaded rod 21 of adjustment stud 2, described unthreaded hole 112 is adaptive with polished rod 22, described adjustment stud 2 adjusts the position of contact 4 by threaded rod 21 and the relative rotation of screwed hole 111, the threaded rod 21 of described adjustment stud 2 is provided with locking nut 3, adjustment stud 2 is locked on support 1 by screwing with threaded rod 21 by described locking nut 3, one end of described polished rod 22 is provided with contact 4, described contact 4 is contacted with the outer cylinder surface of the part 7 be fixed on lathe by lathe spindle 8 and tailstock centre 5, concrete, one end of described polished rod 22 is provided with endoporus 23, the described outer cylinder surface of contact 4 one end and the inner periphery of endoporus 23 fit tightly, the other end of described contact 4 contacts with the outer cylinder surface of part 7, preferably, contact 4 is the cylindrical structurals be made up of carbide alloy, there is very high hardness, intensity, wearability and corrosion resistance, can the quality of strong guarantee processing parts, reduce the distortion of part.
During use, by two ends with the part 7 of the slender axles of centre bore by top and tailstock centre 5 clamping of lathe spindle 8 on lathe, adjust pressure, start the cylindrical of Lathe turning tool turning near the part 7 of tailstock end, the outside diameter size of institute's car is identical with requiring the diameter dimension processed, the cylindrical length of institute's car is a bit larger tham the diameter of this follow-rest upper contact head 4, keeps Lathe turning tool Working position constant.Start this follow-rest is installed, in one end gluing of contact 4 and endoporus 23 tight fit of polished rod 22 one end of adjustment stud 2, the end face of adjustment contact 4 makes itself and the axes normal adjusting stud 2 polished rod 22 part, the adjustment stud 2 having installed contact 4 is screwed with locking nut 3 mutually by the threaded rod 21 of self, turn locking nut 3 is to nut one end of adjustment stud 2, then the adjustment stud 2 with contact 4 and locking nut 3 is combined with support 1, polished rod 22 on adjustment stud 2 coordinates with unthreaded hole 112 small―gap suture on support 1, threaded rod 21 on adjustment stud 2 spins together with the screwed hole 111 on support 1, support 1 is arranged on the attached knife rest 9 of lathe, the center that is basic and lathe spindle 8, Shi Qi center adjusting the contact 4 of this follow-rest front end is contour, adjustment contact 4 end face with along lathe spindle to vertical plane parallel, then by screw, support 1 is pressed on the attached knife rest 9 of lathe, at this moment this follow-rest has just combined.Then this follow-rest is moved to the finished cylindrical position of part 7, contact 4 end face is coated with a little lubricating oil, by rotate adjustment stud 2 with moving contact 4 retreat control contact 4 end face with by the size of part 7 surface contact force of fine finishining, it is made to be applied to the radial cutting force size balance of part 7 with the Lathe turning tool for fine finishining cylindrical, by locking nut 3, adjustment stud 2 is locked on support 1 again, processing parts 7 can be started, simultaneously because follow-rest is on the attached knife rest 9 of the lathe be contained on lathe, so this follow-rest will along with moving together while Lathe turning tool movement, thus ensure that the fine finishining quality of slender axles part.
The present invention efficiently solves existing follow-rest can not the problem that configures without follow-rest of fine finishining slender axles part and some lathes, structure is simple, easy manufacture, adjustment center and quick and easy for installation, the processing circularity of slender axles part is made to reach 0.001mm, cylindricity can reach 0.003mm, and accurately machined slender axles part good rigidly, part deformation is little.
