Abstract
The invention discloses a clamping ring lathe clamp, and relates to the technical field of tool clamp manufacturing. The clamping ring lathe clamp comprises a taper shank with an expansion sleeve part. A plurality of expansion grooves with forward openings are evenly distributed in the outer edge of the expansion sleeve part. An expansion part taper hole communicated with an inner cavity of the expansion sleeve part is formed in the front end of the expansion sleeve part, wherein the front portion of the expansion part taper hole is larger than the rear portion of the expansion part taper hole. The expansion sleeve part is sleeved with a positioning sleeve in a threaded manner. A pressing ring installation part is arranged on the front portion of the positioning sleeve. A central hole communicated with the inner cavity of the expansion sleeve part is formed in the taper shank. A pull rod is arranged in the central hole in a penetrating manner. A taper sleeve with the outer edge matched with the expansion taper hole is arranged on the front portion of the pull rod through threads. Compared with the prior art, the clamping ring lathe clamp can solve the problem that ellipses are prone to appearing when the outer circle of an existing clamping ring is lathed.
Description
Technical field
The present invention relates to frock clamp manufacturing technology field, especially a kind of vehicle clamper of the trim ring on microscope converter.
Background technology
Converter is one of microscopical important parts, and microscopical object lens are then contained on lens barrel by converter; And trim ring is a part on converter, have a kind of trim ring of converter, this trim ring is the thin-wall part of tubular.One of operation of trim ring processing is turning and cut-out; Current trim ring cylindrical turning method is: be enclosed within by the trim ring after interior hole machined and be provided with on the ringfeder of taper shank, re-uses a screw being provided with cone spreading portion by ringfeder spreading by after trim ring tensioner, can carry out turnery processing to trim ring cylindrical.There are the following problems in process of production for this processing method: trim ring is tightening process by screw, its cone spreading portion is directly by the trim ring tensioner on ringfeder, suffered by trim ring, spreading dynamics is uneven, has caused the trim ring cylindrical of processing easily to occur oval phenomenon.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of trim ring vehicle clamper, easily occurs oval problem during to solve existing trim ring turning.
The technical scheme that technical solution problem of the present invention adopts is: this trim ring vehicle clamper comprises the taper shank being provided with ringfeder portion, described ringfeder portion is all be distributed with many openings spreading groove forward in outer rim, the spreading portion taper hole of pre-large post-small connection described ringfeder portion inner chamber is provided with in front end, positioning sleeve is equipped with by thread bush in described ringfeder portion, is provided with trim ring installation portion in described positioning sleeve front portion; Described taper shank is provided with the centre bore being communicated with described ringfeder portion inner chamber, in this centre bore, be coated with pull bar, and described pull bar is equipped with by screw thread the tapered sleeve that outer rim matches with described spreading portion taper hole in front portion.
In above-mentioned trim ring vehicle clamper technical scheme, technical scheme can also be more specifically: described pull bar is provided with thread segment in two ends, and the described thread segment of described back end of tie rod stretches out the rear end of described taper shank.
Further: described taper shank is provided with the dog screw stretching into described pull bar through described ringfeder portion sidewall in described ringfeder portion, described pull bar is provided with the axial location groove clamping described dog screw front portion.
Refer to before indication of the present invention taper shank be provided with side, ringfeder portion towards.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: owing to being set with the positioning sleeve with trim ring installation portion outside the ringfeder portion of taper shank, and tapered sleeve is pulled back by pull bar and opened in ringfeder portion, tension force is passed on trim ring and by trim ring by the ringfeder portion of taper shank, the trim ring installation portion of positioning sleeve again and overlaps base tensioner; Therefore, the radial tension of trim ring cover suffered by base is even, and the phenomenon of ovalizing deflection does not appear in trim ring cylindrical on inspection that complete processing.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is trim ring 7-1, need cut off to obtain trim ring 7-1 after carrying out turnery processing to the cylindrical of trim ring cover base 7 as shown in Figure 2.
Trim ring vehicle clamper as shown in Figure 2 comprises the taper shank 1 being provided with ringfeder portion 1-3, the ringfeder portion 1-3 of the present embodiment is all be distributed with four openings spreading groove 1-2 forward in outer rim, ringfeder portion 1-3 is provided with the spreading portion taper hole 1-1 of pre-large post-small connection ringfeder portion inner chamber in front end, as shown in Figure 3 and Figure 4; Outside the ringfeder portion 1-3 of taper shank 1, by thread bush, positioning sleeve 2 is housed, is provided with trim ring installation portion 2-1 in positioning sleeve 2 front portion; Taper shank 1 is provided with the centre bore being communicated with ringfeder portion inner chamber, and in this centre bore, be coated with pull bar 5, pull bar 5 is provided with thread segment in two ends, and the thread segment of pull bar 5 rear end stretches out the rear end of taper shank 1, and pull bar 5 is provided with location shell of column between two thread segments; The thread segment of pull bar 5 in front end is equipped with by screw thread the tapered sleeve 4 that outer rim matches with spreading portion taper hole 1-1, and tapered sleeve 4 is contained on the thread segment of pull bar 5 front end by nut 3; The ringfeder portion of taper shank 1 is equipped with the dog screw 6 stretching into pull bar 5 through ringfeder portion sidewall, pull bar 5 has the axial location groove clamping dog screw 6 front portion, the front portion of dog screw 6 is stretched in axial location groove, when pull bar 5 is stressed tapered sleeve 4 pulled back tensioner trim ring cover base 7 time, pull bar 5 is subject to the spacing of dog screw 6.
During work, first this trim ring vehicle clamper is contained in the cone hole part of the centre bore of lathe by taper shank 1, the centre bore making pull bar 5 pass lathe stretches out the tail end of lathe, and installs top board and nut successively on the thread segment of pull bar 5 rear end; Trim ring cover base 7 is enclosed within the trim ring installation portion 2-1 of positioning sleeve 2, the tail end of pressing plate and lathe is abutted against and tightens the nut on the thread segment of pull bar 5 rear end, trim ring being overlapped base 7 tensioner on the trim ring installation portion 2-1 of positioning sleeve 2; Start lathe, after adopting lathe tool to carry out turnery processing to trim ring cover base 7 cylindrical, cut off to obtain trim ring 7-1.
