Abstract
The invention discloses a fast clamp and fast demounting device for a machine tool center. The fast clamp and fast demounting device comprises a support. A first mounting hole and a second mounting hole which are in the same horizontal plane, vertical to each other and communicated are formed in the support. A slide rod is mounted in the first mounting hole. A pressure spring is disposed between the inner end of the slide rod and the bottom of the first mounting hole. The lateral side, located at the second mounting hole, of the slide rod is a slope. A movable center is disposed in the second mounting hole, the outer tip of the movable center extends out of the second mounting hole and is used for positioning a stepped mandrel, and the inner end of the movable center is abutted against the slope of the slide rod. A V-shaped block is disposed on the lateral side of the support, the V-shaped corner of the V-shaped block is hinged to the support, one support leg of the V-shaped block is abutted against the outer end face of the slide rod, the other support leg of the V-shaped block is hinged to a connecting rod which can force the support leg to swing horizontally, and the connecting rod is driven by a drive structure.
Description
Technical field
The present invention relates to machine tool accessories, be specifically related to the top fast folder Quick-disassembling device of a kind of lathe.
Background technology
Gear is automotive transmission, the isostructural basic part of synchronized.The processing of gear comprises crowded teeth, shaving, cylindrical grinding etc.Location is realized by lathe is top during usual Gear Processing, specifically geared sleeve being connected on two ends has on the ladder mandrel of tapering blind hole, side is spacing by the shaft shoulder, opposite side is locked by cushion cover, is then placed in by ladder mandrel between the stationary center of lathe and rolling center and realizes location.At present, normally adopt lever operated worm gear structure to control rolling center handling ladder mandrel, Problems existing is that manual operation is slow, continuity is strong, affects the working (machining) efficiency of gear.
Summary of the invention
The invention provides a kind of top fast folder Quick-disassembling device of lathe improving Gear Processing efficiency.
This programme is as follows: the top fast folder Quick-disassembling device of lathe, comprise bearing, bearing is provided with two mutually vertical and the first installing hole communicated and the second installing holes in same level, slide bar is provided with in first installing hole, stage clip is provided with between at the bottom of the inner of slide bar and hole, the side that slide bar is positioned at the second installing hole place is inclined-plane, rolling center is provided with in second installing hole, the second installing hole is stretched out for locating ladder mandrel in the outer tip of rolling center, the inner of rolling center is held by the inclined-plane of slide bar, the side of bearing is provided with vee-block, the V-arrangement turning of vee-block is hinged on bearing, a leg of vee-block and slide bar outer face offset, another leg and one can force this leg horizontal hunting rod hinge connection, described connecting rod is driven by drives structure.
This programme operation principle is as follows: when rolling center needs to hold out against ladder mandrel, under the drive of drives structure, connecting rod travels forward, make one end forward swing that vee-block is connected with connecting rod, and one end that vee-block and slide bar offset will force slide bar to slide at the bottom of hole along the first installing hole, the inclined-plane on slide bar will hold out against the tapering blind hole of ladder mandrel by forcing rolling center along the second installing hole advance; Otherwise connecting rod retreats under the drive of drives structure, then put behind the one end driving vee-block to be connected with connecting rod, the other end and the slide bar outer end of vee-block depart from, and under the effect of stage clip, slide bar outwards moves along the first installing hole, under the effect on inclined-plane, top retrogressing, unclamps ladder mandrel.
To sum up, the present invention can realize the fast folder quick-release action of machine tool live center, can improve the handling speed of ladder mandrel, improves the working (machining) efficiency of gear.
Further, drives structure comprises horizontally disposed cylinder, cylinder is divided into the first chamber and the second chamber by the piston being arranged on cylinder interior, the wall of the first chamber has port, the middle part of piston is connected with vertical piston rod, the lower end of piston rod and one end of fork hinged, the middle part of fork is articulated with on the back shaft that is arranged on the second chamber wall, vertical fairlead is provided with in the side direction of cylinder, slide block is provided with in fairlead, the bottom of slide block is supported by the other end of fork, and the top of slide block and the lower end of connecting rod are fixed.Fairlead, when slide block movement, has guide effect to slide block.Pneumatic drivening rod action, structure is simple, easy to operate.
Further, the V-arrangement turning of vee-block is hinged on a pedestal, and pedestal is detachably connected on bearing by screw.When needing to shift whole device, pedestal can be dismantled, taking up room of less whole device, be convenient to transfer and safeguard.
