Description
Technical field
The invention belongs to field of machining, are related to a kind of both ends independence ringfeder regulating mechanism of near closed hollow ring.
Background technique
Expansion set is commonly used a kind of expanding structure in a kind of lathe equipment, and general expansion set structure is mostly one end swelling, or
The structure type of both ends swelling simultaneously, single pair is that there are walls due to part both ends in the both ends swelling of a Chang Yuanzhu class an actor's rendering of an operatic tune
Thick inconsistent, internal control not coaxially Eng problem in both ends causes the deflection of part during expansion set swelling different and causes part
Phenomena such as deformation or insufficient swelling amount before processing, the problems such as seriously affecting the machining accuracy of part, even result in part rejection.
Summary of the invention
The purpose of the present invention is: it can be realized mechanism both ends and independently compress expansion set part.
The technical scheme is that
In a first aspect, providing a kind of both ends independence ringfeder regulating mechanism of near closed hollow ring, comprising: the positioning spiral shell of both ends positioning
Bar, two be provided with the expansion set part of location hole, two press part；The end of positioning screw is provided with limiting slot；
Wherein, the both ends of positioning screw are each passed through the location hole of left expansion set part；The left end of positioning screw is stretched out left swollen
The right end of external member, positioning screw stretches out right expansion set part；When locating part presses the right end that part gos deep into positioning screw by the right side
Limiting slot, positioning screw limit in a circumferential direction, and part cooperation is pressed on left expansion set part and a left side, by left expansion set part towards in positioning screw
Between direction clamp, realize left expansion set part swelling；After left expansion set part swelling, locating part presses part by a left side and gos deep into positioning screw
Left end limiting slot, positioning screw limits again in a circumferential direction, and part cooperation is pressed on right expansion set part and the right side, by right expansion set
Part is clamped towards the direction among positioning screw, realizes right expansion set part swelling.
Further, location hole and there are gaps across the screw rod of location hole.
Further, expansion set part further include: washer, conical surface briquetting, expansion set, pressing plate；
Washer is fixedly connected with expansion set；Conical surface briquetting is in stress, along the axial movement of positioning screw, the cone of conical surface briquetting
Face pushes expansion set distending until expansion set is pressed on pressing plate.
Further, two expansion set parts are symmetrically installed.
Further, the compactness of expansion set and the conical surface is greater than or equal to 80%.
Further, the diameter of washer is greater than the maximum gauge of expansion set under free state, and it is straight to be less than the minimum after distending
Diameter.
Further, pressing part is hexagonal socket nut, and locating part is allen wrench.
Further, hexagonal socket nut includes: pressing sleeve, nut, straight pin；
Wherein, pressing sleeve and nut are entirely through cylinder pin connection, to realize that hexagonal socket nut presses conical surface briquetting.
Further, washer is polyurethane washer.
The invention has the advantages that before solving the deflection difference of part during expansion set swelling and part being caused to process
The problems such as deformation or swelling amount are insufficient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of present clip and pinion cutter.Chain-dotted line in Fig. 1 is blocked with processed
The design of part schematic diagram of incomplete circumference gear.
Specific embodiment
The present invention is described in further details below.
As shown in Figure 1, the present invention provides a kind of both ends independence ringfeder regulating mechanism of near closed hollow ring.The mechanism includes: interior
Hex nut 01, positioning screw 02, polyurethane washer 03, conical surface briquetting 04, expansion set 05, pressing plate 06, pressing plate 07, expansion set 08, cone
Face pressure block 09, pressing sleeve 01-1, straight pin 01-2, nut 01-3.
Wherein, it is connect with nut 01-3 entirely through straight pin 01-2 by pressing sleeve 01-1, constitutes the interior hexagonal an of entirety
Nut 01.By 01~09 separately adjustable expansion set part in the integral both ends of group.
(1) sequence expansion set all parts are assembled in place by shown in figure；
(2) (expansion set at this time in the cylinder an actor's rendering of an operatic tune for such as needing swelling is placed by the separately adjustable expansion set mechanism in assembled both ends
It in free state, does not compress)；
(3) 02 left end of positioning screw is fixed with using die nut, is then turned six in right end using die nut again
Angle screw 01, with the rundown process of soket head cap screw 01, conical surface briquetting 09 is constantly to central pressing, 08 distending of expansion set at this time,
Swelling part, under this state, since left end conical surface briquetting 04, expansion set 05 do not stress, still in free state, when right end is swollen
Set 08, distending in place when；
(4) hexagonal socket nut 01 is similarly adjusted, 05 distending of expansion set is made, to realize swollen to the independence at two pieces cylinder both ends
Tightly.
Note: adjusting sequence in left and right ends can choose at random existing that one end of adjusting, can also adjust simultaneously.
