Description
Technical field
The present invention relates to mechanical fixture technology field, particularly relate to the scroll chuck of clamping automatically.
Background technology
Scroll chuck is clamping device general in machining; Current scroll chuck is by swinging handle, claw is moved thus holding workpiece; But this scroll chuck exists following point: 1) complex structure, after long-time use, after there is stuck phenomenon, dismounting difficulty; 2) automaticity is not high, and need clamping manually, production efficiency is low.
Summary of the invention
The object of this invention is to provide can automated exchanged cutter workpiece, and the scroll chuck of the automatic clamping of easy accessibility.
Technical scheme of the present invention is as follows:
The scroll chuck of automatic clamping, comprises discoid base; Described base is evenly equipped with three flutings, fluting medial surface is equipped with the first screw, is all provided with clamping device in this first screw; Described clamping device comprises screw rod, and screw rod is provided with moveable Mobile base, and the claw that Mobile base connects; Described screw rod one end extends outside the base and is connected with motor; Described claw is equipped with " V " shape fluting towards the one end at base center; Described " V " shape fluting both sides are equipped with pressure sensor, and the output of this pressure sensor is all electrically connected controller, and controller output end connects three control motor start and stop contactors respectively.
Described fluting both sides are relatively set with two slide rails; Described Mobile base both sides are provided with two chutes relatively; Described slide rail and chute with the use of.
Described base center is provided with the second screw, is provided with backstay in this second screw; Be provided with bottom described backstay with the second screw with the use of threaded portion; Backstay outer surface above described threaded portion is evenly equipped with some spring leafs.
Described slide rail is in " convex " font; Described chute is in " convex " font.
The invention has the beneficial effects as follows: drive the rotation of screw rod by the startup of motor and then drive the movement of Mobile base, the mobile claw be connected with Mobile base that drives of Mobile base moves forward and backward; When claw move to prop up cylindrical workpiece time, disable motor, makes three claws be clamped by cylindrical work; Because claw is provided with " V " shape fluting towards the one end at base center, adopt " V " shape fluting effectively can clamp cylindrical work; By arranging pressure sensor, when " V " shape fluting contacts with cylindrical workpiece, pressure sensor is by Signal transmissions to controller, and controller controls the out of service of motor by the second contactor; When needs holding workpiece, controller controls the startup of motor by the first contactor.
