Abstract
The invention discloses an adjustable eccentric three-jaw chuck fixture. The adjustable eccentric three-jaw chuck fixture comprises a chuck body (1), a shim plate (2), clamping jaws (3) and an adjustable clamping jaw (4), wherein the shim plate (2) is installed on the chuck body (1), and the clamping jaws (3) and the adjustable clamping jaw (4) are installed on the shim plate (2). A clamping jaw slide base (5) is installed on the chuck body (1) and provided with a hole, a threaded rod (6) is installed in the hole formed in the clamping jaw slide base (5), and the clamping jaw slide base (5) is in clamping fit connection with the threaded rod (6). According to the adjustable eccentric three-jaw chuck fixture provided by the invention, the structural design is reasonable, operation is convenient, and clamping is stable and reliable; the eccentric magnitude is convenient to adjust, requirements for adjusting of different eccentric magnitudes can be met, and good flexibility and convenience are achieved; and an eccentric part obtained through machining is high in quality, precision and practicality.
Description
Technical field
The present invention relates to a kind of machinery, be specifically related to a kind of adjustable eccentric scroll chuck fixture.
Background technology
In machine driving, the general conversions using fast (connecting rod) mechanism of slide crank to realize forms of motion more, make gyration
Being changed into linear reciprocating motion or make linear reciprocating motion be changed into gyration, the part such as eccentric shaft, crank, bent axle is all normal
Eccentric work piece.When prior art clamping chuck assembly processes eccentric work piece on lathe, offset size tends not to adjust
Or adjusting inconvenience, the eccentric work package of engine lathe processing, on scroll chuck, shimming or rule with chuck is looked for partially always
The heart away from, can turning, the most both wasted a lot of man-hour, operation is inconvenient again, and the eccentric part processed is of low quality.
Therefore, necessary on the basis of existing technology, a kind of reasonable in design of research and development, easy to use, offset
Size is easy to adjust, clamps reliable and stable, and the eccentric part quality that processing obtains is high, and precision is high, practical adjustable eccentric three
Dog chuck fixture.
Summary of the invention
Goal of the invention: the invention aims to solve the deficiencies in the prior art, it is provided that a kind of reasonable in design, user
Just, offset size is easy to adjust, clamps reliable and stable, and the eccentric part quality that processing obtains is high, and precision is high, practical
Adjustable eccentric scroll chuck fixture.
Technical scheme: in order to realize the purpose of the present invention, the technical solution used in the present invention is:
A kind of adjustable eccentric scroll chuck fixture, it includes chuck body, the parallels being arranged on chuck body, is arranged on parallels
Claw and adjustable claw, described chuck body is provided with claw slide, claw slide is offered porose, and screw rod is arranged on claw
In the hole offered on slide, claw slide and screw rod snap-fit connection.
Preferably, above-described adjustable eccentric scroll chuck fixture, described chuck body is provided with and screws body.
Preferably, above-described adjustable eccentric scroll chuck fixture, described claw is stairstepping.
Preferably, above-described adjustable eccentric scroll chuck fixture, described parallels is fan-shaped, is fastened by screw
At chuck body.
The adjustable eccentric scroll chuck fixture that the present invention provides, being changed into by a wherein pawl can be radially on claw slide by screw rod
The structure of positioning is moved in direction, offset size the most according to actual needs can adjust position, such that it is able to meet difference
The processing request of offset, clamps after adjusting offset, then screws body by rotation, and three-jaw can complete eccentric clamping, side
Just process.
Beneficial effect: compared to the prior art the adjustable eccentric scroll chuck fixture that the present invention provides has the advantage that
The adjustable eccentric scroll chuck fixture that the present invention provides, reasonable in design, easy to operate, clamp reliable and stable, eccentric
Amount size is easy to adjust, can meet the adjustment of different offset, and the most flexibly and easily, the eccentric part quality that processing obtains is high, essence
Degree height, practical.
