Description
Technical field
The utility model relates to a kind of anchor clamps, specifically a kind of novel air heave type spring chuck.
Background technology
At present, existing frock spring chuck mostly is manual expansion sleeve type anchor clamps greatly, and its expansion set external diameter is to be the rigidity locating surface, because foozle, the expansion set external diameter often has only some points to contact with the clamping workpiece, easily causes the center line of positioning cylindrical surface and surface to be machined not parallel, and machining accuracy is lower.On the other hand, manually pine is pressed from both sides complex operation aborning, greatly influences production efficiency, and manually clamping force does not wait at every turn, makes the deflection difference of each workpiece before turning, can influence the machining accuracy of workpiece yet.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, a kind of novel structure, reasonable in design is provided, economical and practical, utilize cylinder and light-wall pipe structure on the anchor clamps, realization is carried out self-centering and clamping to workpiece, the conveniently assemble and disassemble workpiece need not manually pine folder operation, improves the novel air heave type spring chuck of clamping, positioning accuracy and workpiece working (machining) efficiency greatly.
In order to achieve the above object; The technical solution adopted in the utility model is: comprise cylinder casing; Light-wall pipe; Steam-cylinder piston; Sealing ring; Catch; Passage; The clamping axle; The top locating slot of first lathe; The top locating slot of second lathe; Seal groove; Screw assembly hole and boss; Have the Screw assembly hole on the left end sidewall of wherein said cylinder casing; The left end of light-wall pipe links to each other with the clamping axle; The left end center of clamping axle has the top locating slot of first lathe; The right-hand member of light-wall pipe has boss, has attacked screw thread on the external cylindrical surface of boss, and light-wall pipe is contained on the Screw assembly hole of cylinder casing left end by the screw thread on the boss; Have passage on the piston body of steam-cylinder piston; On the piston body of steam-cylinder piston, catch is equipped with at the place, aperture that is positioned at the passage left end, has seal groove on the piston body external cylindrical surface of steam-cylinder piston; Sealing ring is housed on the seal groove; Steam-cylinder piston is contained in the inside of cylinder casing, and back-moving spring is contained between the right side of steam-cylinder piston left side and cylinder casing left side cylinder wall, and the piston rod right-hand member center of steam-cylinder piston has the top locating slot of second lathe.
The utility model has the advantages that:
Because the utility model designs cylinder and light-wall pipe structure on anchor clamps, can directly utilize the pressure of top of lathe to make the light-wall pipe dilatancy, and when removing the pressure of top of lathe; light-wall pipe can shrink reduction again automatically; can realize self-centering and clamping to workpiece; and the conveniently assemble and disassemble workpiece, need not manually pine folder operation, thereby improved clamping, positioning accuracy and the workpiece working (machining) efficiency of workpiece greatly

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 4 as can be known; The utility model comprises cylinder casing 1; Light-wall pipe 2; Steam-cylinder piston 3; Sealing ring 4; Catch 5; Passage 6; Clamping axle 7; The top locating slot 8 of first lathe; The top locating slot 9 of second lathe; Seal groove 10; Screw assembly hole 11; Boss 12 and back-moving spring 13; Have Screw assembly hole 11 on the left end sidewall of described cylinder casing 1; The left end of light-wall pipe 2 links to each other with clamping axle 7, and the left end center of clamping axle 7 has the top locating slot 8 of first lathe, and the right-hand member of light-wall pipe 2 has boss 12; Attacked screw thread on the external cylindrical surface of boss 12; Light-wall pipe 2 is contained on the Screw assembly hole 11 of cylinder casing 1 left end by the screw thread on the boss 12, has passage 6 on the piston body of steam-cylinder piston 3, on the piston body of steam-cylinder piston 3; Catch 5 is equipped with at the place, aperture that is positioned at passage 6 left ends; Have seal groove 10 on the piston body external cylindrical surface of steam-cylinder piston 3, sealing ring 4 is housed on the seal groove 10, steam-cylinder piston 3 is contained in the inside of cylinder casing 1; Back-moving spring 13 is contained between the right side of steam-cylinder piston 3 left sides and cylinder casing 1 left side cylinder wall, and the piston rod right-hand member center of steam-cylinder piston 3 has the top locating slot 9 of second lathe.
During work, processing parts is contained on the light-wall pipe 2, and utilizes the left side of boss 12 to carry out the axial location of workpiece; Anchor clamps by top locating slot 8 of first lathe at its two ends, left and right sides and the top locating slot 9 of second lathe be contained in lathe two the location top between.Owing to have pressure between lathe two location are top, can promote steam-cylinder piston 3 to left movement, thereby the volume of cylinder casing 1 inner chamber is reduced, the pressure of cylinder interior is increased.The inside cavity air pressure that this moment, cylinder casing 1 and light-wall pipe 2 were formed is greater than external atmosphere pressure, and catch 5 compresses, and passage 6 is closed; Light-wall pipe is owing to the effect that is subjected to air pressure inside expands, and workpiece is located, clamping thereby make.When process finishing, remove the pressure of top of two lathes, steam-cylinder piston 3 is owing to the effect that is subjected to back-moving spring 13 moves right, this moment, catch 5 was opened, atmosphere is owing to the effect that is under pressure flows to pneumatic cylinder, and the inside cavity air pressure that this moment, cylinder casing 1 and light-wall pipe 2 were formed constantly reduces, and finally is reduced to initial level; light-wall pipe 2 shrinks and recovers, and workpiece can unload.Thereby realize self-centering and clamping to workpiece, and the conveniently assemble and disassemble workpiece, need not manually pine folder operation, improved clamping, positioning accuracy and the workpiece working (machining) efficiency of workpiece greatly.
