Abstract
A low-cost and simple assembly process pneumatic clamp device contains a machine tool spindle and a collet . A fixed seat is fixed by bolts on the spindle of the machine tool. The chuck body is fitted on the fixed seat. The collet chuck fixed is fixed on the chuck body. A gland is fixed on the front end of the chuck body. The chuck body, collet chuck and the gland together form a sealed cylinder with a piston in it. The invention has advantages of simple technology and low cost.
Description
Technical field
The present invention relates to a kind of machine tools, relate in particular to a kind of in machining employed a kind of air clamper during metal cutting.
Background technology
At present, employed lathe clamping device mainly comprises when machining workpiece: rotary main shaft, rotary cylinder; : the front end of rotary main shaft has air spider, rotary cylinder is installed in the afterbody of the rotary main shaft of lathe, have pull bar to be connected with the air spider of main rotating shaft front end on the rotary cylinder, the piston by rotary cylinder moves the pull bar that makes on the rotary cylinder and moves, and opens, contracts thereby drive air spider; Make workpiece on the chuck clamped or unclamp, though this kind clamping device also can be realized the automation that workpiece clamps, it needs a huge pneumatic rotary cylinder, thereby makes the production cost height, organizes the production cycle long, the assembly technology complexity.
Summary of the invention
It is low to the purpose of this invention is to provide a kind of production cost, the simple a kind of air clamper of assembly technology.
For achieving the above object, the technical solution adopted in the present invention is: a kind of air clamper, comprising: machine tool chief axis, chuck; Its characteristics are: described chuck is a collet, described machine tool chief axis Front-end Design has holder, holder is fixed on the machine tool chief axis by screw, the holder Front-end Design has collet body, collet body is installed on the holder by screw, and collet is fixedly mounted on the collet body by screw; The Front-end Design of collet body has gland, and gland is fixedly mounted on the collet body by screw, and collet body, collet, gland surround the cylinder of a sealing jointly, and piston is installed in the cylinder.
Advantage of the present invention is: because the cylinder among the present invention is to be surrounded jointly by collet body, collet, gland, so assembly technology of the present invention is simple, production cost is low.

Fig. 2 looks schematic diagram for Fig. 1 right side;
Fig. 3 is a medi-spring chuck structure schematic diagram of the present invention;
Fig. 4 looks schematic diagram for Fig. 3 right side;
Fig. 5 is gland structure schematic diagram among the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is further described;
A kind of air clamper, shown in Fig. 1,2,3,4,5, comprising: common machine tool chief axis, chuck; Chuck is a collet 4, the machine tool chief axis Front-end Design has holder 1, and holder 1 is fixed on the machine tool chief axis by screw, and holder 1 Front-end Design has collet body 2, collet body 2 is installed on the holder 1 by screw, and collet 4 is fixedly mounted on the collet body 2 by screw; The Front-end Design of collet body 2 has presses 5, and gland 5 is fixedly mounted on the collet body 2 by screw; Collet body 2,4 of spring clips, gland 5 surround the cylinder of a sealing jointly, and piston 3 is installed in the cylinder.
Operation principle of the present invention is: gas enters in the holder 1 by the gas passage of machine tool chief axis, enter in the cylinder then, promote piston 3 outer moving, make collet 4 stressed back spreadings or be in physical slot, when collet was in spreading, workpiece just was in released state, when collet is in physical slot, workpiece just is in clamped state, thereby workpiece is exactly to be pushed by collet to make it to clamp or unclamp the clamping that has realized workpiece or unclamp.
