The elastic clamp for the lathe processing support has the advantages that the clamp position is in non-clearance fit, self-locking performance is good, and chattering caused by centrifugal force is reduced and size precision and coaxiality precision of processing part are improved by using an adjustable pressing plate to compress the clamp tightly.
Description
Technical field
The utility model relates to the anchor clamps that machining support is used on a kind of engine lathe, particularly a kind of Vehicle Processing support spring chuck.
Background technology
The tradition machining support uses the keeper of anchor clamps shown in figure four, adopt the cylindrical mandrel location, adopt matched in clearance between part to be processed and the locating shaft, when the main shaft High Rotation Speed, workpiece has formed the cantilever beam state, produces very large centrifugal force, makes workpiece produce very large chatter, can't guarantee dimensional accuracy and the coaxial accuracy of workpiece, sometimes even can't process.
Summary of the invention
Problem in view of the prior art existence, the utility model provides a kind of Vehicle Processing support spring chuck, these anchor clamps adopt the elastic expansion-sleeve location, part to be processed adopts gapless to cooperate with setting element, self-locking property is good, and the chatter that causes for reducing centrifugal force, anchor clamps adopt the capable of regulating pressing plate to compress, strengthen clamping force, thereby limited centrifugal motion and the radially wobbling of workpiece of part to be processed in process.
The utility model for achieving the above object, the technical scheme that adopts is: a kind of Vehicle Processing support spring chuck, it is characterized in that: comprise driver plate, elasticity location ringfeder, core rises, Compress Spring, flat key, adjusting rod, the nut I, spring washer, attachment screw, housing screw, supporting screw, the Anti-extrusion screw, pressure-adjustable plate, packing ring, the nut II, packing ring, the nut III, described flat key embeds in the keyway of adjusting rod, one end of described adjusting rod passes the location endoporus of elasticity location ringfeder, pass through spring washer, the nut I is fixed on the ringfeder of elasticity location, the other end that described Compress Spring is inserted in adjusting rod places in the groove of elasticity location ringfeder, be embedded with the core that rises of flat key, packing ring, the nut III is packed on the other end of adjusting rod successively, the core that rises is by conical tight-lipped cooperate of nut III with the little cylindrical of elasticity location ringfeder, an end and the Compress Spring compression fit of core rise, the large cylindrical of described elasticity location ringfeder places the round recessed of driver plate, fix by several screws and driver plate, connect respectively a supporting screw on two described pressing plates, one end of two described housing screws is respectively charged in the dovetail groove at driver plate two ends, the other end of two described housing screws passes respectively pressing plate and is connected with the nut II, the other end of the supporting screw that connects on the pressing plate contacts respectively cooperation with driver plate, two described Anti-extrusion screws are screwed into respectively in two screws that driver plate is provided with.
The beneficial effects of the utility model are: this anchor clamps location adopts gapless to cooperate, and self-locking property is good, the chatter that causes for reducing centrifugal force, anchor clamps adopt the capable of regulating pressing plate to compress, strengthen enough clamping forces, compact conformation, simple, anchor clamps are connected safe and reliable with main shaft; Dimensional accuracy and the coaxial accuracy of processing parts have been improved.
