Abstract
The invention discloses a regulable eccentric chuck. The regulable eccentric chuck comprises a fixing chuck, a clamping chuck and a positioning flange plate, wherein the positioning flange plate is fixedly clamped on the fixing chuck, and a plurality of mounting holes are formed in the positioning flange plate; the clamping chuck is fixedly mounted on the positioning flange plate through the mounting holes, the mounting holes adopt a bar-shaped groove structure, the mounting holes are mutually in parallel in the lengthwise direction, a threaded hole is formed in one jack catch on the clamping chuck, and a positioning bolt is mounted in the threaded hole. The regulable eccentric chuck disclosed by the invention is reformed from a general three-jaw chuck, can be used for production of eccentric parts in batches, and has high production efficiency; the processing accuracy can be effectively controlled through rough regulation and fine regulation in the process of using the regulable eccentric chuck, and the regulable eccentric chuck has the characteristics of high efficiency, high accuracy and low cost.
Description
Technical field
The present invention relates to a kind of chucks, particularly a kind of eccentric chuck of adjustable eccentric distance.
Background technology
Eccentric work piece is exactly cylindrical and the cylindrical of part, or the axis being parallel of cylindrical and endoporus and the workpiece of the certain distance that do not coincide, departs from.When processing this kind of eccentric element, normally taking measures in clamping, namely the axis centering of the eccentric part needing processing being coincided to lathe spindle rotation.The method of general car eccentric work piece has two kinds: (1) carrys out eccentric clamp workpiece by cushion block on three-jaw or chuck, and this method working (machining) efficiency is low and precision is poor; (2) to get on the bus eccentric work piece at special fixture, although adopt special fixture to carry out processing and can ensure machining accuracy well, cost is higher, and versatility is poor.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above, provide one to ensure clamping precision, and can carry out according to the eccentric throw of workpiece the adjustable eccentric chuck that adjusts.
For solving the problems of the technologies described above, present invention employs following technical scheme:
Adjustable eccentric chuck, comprise fixing chuck, chucks and locating flange dish, described locating flange dish fixes clamping on fixing chuck, described locating flange dish is provided with multiple installing hole, described chucks is fixedly mounted on locating flange dish by installing hole, and described installing hole is bar-shaped trough structure, and described installing hole is parallel to each other along its length, a claw on described chucks is provided with screwed hole, in described screwed hole, bolt is installed.
Further, in the present invention, described fixing chuck and chucks all adopt scroll chuck.
The beneficial effect that the present invention has:
1) this adjustable eccentric chuck adopts the transformation of Universal three-jaw chuck, with low cost;
2) eccentric throw of this chuck can need to adjust according to the processing of workpiece, and versatility is better;
3) eccentric throw of this chuck is fixedly mounted on the position of installing hole and bolt by chuck for installing and carries out combination and regulate, and wherein the adjustment position of installing hole is comparatively large, for the coarse adjustment of eccentric throw; The adjustment distance of bolt is less, and for the accurate adjustment of eccentric throw, regulated by combination, machining accuracy easily ensures, easy to operate.

Fig. 2 is locating flange dish A-A direction view of the present invention.
In figure, 1, fixing chuck; 2, locating flange dish; 3, chucks; 4, installing hole; 5, claw; 6, bolt; 7, screwed hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
With reference to Fig. 1, for a kind of adjustable eccentric chuck, comprise fixing chuck 1, chucks 3 and locating flange dish 2, described locating flange dish 2 fixes clamping on fixing chuck 1, described locating flange dish 2 is provided with multiple installing hole 4, described chucks 3 is fixedly mounted on locating flange dish 2 by installing hole 4, described installing hole 4 is bar-shaped trough structure, described installing hole 4 is parallel to each other along its length, a claw 5 on described chucks 3 is provided with screwed hole 7, in described screwed hole 7, bolt 6 is installed.
In the present invention, described fixing chuck 1 and chucks 3 all adopt scroll chuck.
Fixing chuck 1 is arranged on the main shaft of lathe, then by locating flange dish 2 clamping on fixing chuck 1, chucks 3 is connected with locating flange dish 2 by bolt.During use, by chucks 3 directly holding workpiece, first use the dial gauge of magnetic force dial framework, correct the external diameter jerk value of chucks 3; Before correction, the bolt that chucks 3 connects with locating flange dish 2 is not twisted too tight, when the radial beat eccentricity of dial gauge instruction after chucks 3 rotates a circle is close to eccentric throw, bolt tightening, chucks 3 is made to be connected on locating flange dish 2 securely, adjust the bolt 6 on the claw 5 of chucks 3 again, workpiece eccentric throw is finely tuned, with the dial gauge of magnetic force dial framework, the external diameter jerk value of measuring workpieces, after workpiece is rotated a circle, when the radial beat eccentricity of dial gauge instruction equals eccentric throw, just can process.
