Description
Technical field
The utility model relates to a kind of placing device of lathe hand chuck spanner, particularly the safe homing device of a kind of lathe chuck spanner.
Background technology
Lathe chuck rotates for holding workpiece.Lathe chuck has the disk of axis on same straight line of axis and lathe power output shaft, a plurality of radially movable jaws are arranged on the card of disk, for hand chuck, the drive end that the claw activity is arranged on the circumference of disk, drive end has radially four directions to pull hole, and chuck handle is to pull with the drive end four directions manual drive matched in hole.Chuck handle has the straight rod-shaped wrench body, and the upper end of wrench body is connected with handle, and the lower end of wrench body is connected with above-mentioned four directions and pulls the cubic spanner matched in hole.The cubic spanner of chuck handle being inserted to the four directions of lathe chuck pulls in hole, use the manual rotation handle, a plurality of claw radial motions on can drive chuck, when holding workpiece, allow the centripetal motion of claw, workpiece is clamped in tightly in a plurality of claws of chuck, while taking off workpiece, allow the claw centrifugal motion, workpiece is taken out from a plurality of claws.After holding workpiece, take off chuck handle, start the lathe power output shaft and rotate, drive chuck rotary cutting workpiece with the lathe power output shaft.
In the actual production of turner, particularly begin to learn in the student of turner technology, the Chang Youyong chuck handle is after piece-holder is on chuck, forget chuck handle is taken off and just starts the rotation of lathe power output shaft from chuck, the lathe power output shaft drives when chuck rotates and can drive the chuck handle rotation or allow chuck handle pull hole and to fly out from four directions, the security incident that causes damage equipment or hurt sb.'s feelings.
In order to prevent with chuck handle after piece-holder is on chuck, because forget chuck handle is taken off from chuck, security incident occurs after causing the startup lathe.In prior art, in Chinese patent 2,008 2 0185320.9, disclose a kind of can be from pull hole the chuck handle of automatic spring, this chuck handle has the straight rod-shaped wrench body, the upper end of wrench body is connected with handle, the lower end of wrench body is connected with above-mentioned four directions and pulls the cubic spanner matched in hole, on wrench body, having can be chuck handle from pulling the elastic ejection mechanism ejected in hole, elastic ejection mechanism has axis in wrench body and the axis shoulder hole that Open Side Down on same straight line of wrench body, there is the ladder push rod matched in the ladder aperture, between upper end in shoulder hole and ladder push rod, spring is arranged.When holding workpiece, pull in hole in the four directions that hand-held chuck handle inserts lathe chuck to the cubic spanner of chuck handle downwards, overcoming spring force after the ladder push rod is under pressure makes progress in the indentation shoulder hole, rotary handle drives the centripetal motion of claw, after having clamped workpiece, when hand leaves chuck handle, removed the power downward to chuck handle, the ladder push rod stretches out shoulder hole because of spring force, and chuck handle is ejected from pulling in hole, and chuck handle is separated with chuck.This can be from pull hole the chuck handle of automatic spring, although, after having clamped workpiece, can allow chuck handle break away from chuck, the security incident that prevents damage equipment or hurt sb.'s feelings occurs, but chuck handle ejects naturally from pulling in hole, irregularly falls, and dangerous and uncultivated defect is also arranged.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, propose a kind of can prevent with chuck handle after piece-holder is on chuck, because forget, chuck handle is taken off and causes the safe homing device of lathe chuck spanner of security incident from chuck.
The utility model is realized with the following method.
The safe homing device of lathe chuck spanner has the hexahedron housing, the wrench body jack that chuck handle is arranged above housing, in housing, it is the wrench body pallet of the face of falling truncated rectangular pyramids shape that there is inner chamber wrench body jack below, the face of falling the truncated rectangular pyramids inner chamber of the wrench body pallet cubic hole of having gone to the bottom, in housing, the below of wrench body pallet has push type often to drive microswitch, in housing, the contact of often driving microswitch is hinged on the elastic rocking beam in housing to being connected with upper end, below the cubic hole of going to the bottom at the wrench body pallet in the lower end of elastic rocking beam, often opening the switching signal output of microswitch draws from housing.
The utility model should be designed to: the size of the wrench body jack size above housing and the wrench body pallet face of falling truncated rectangular pyramids shape inner chamber matches with the wrench body size of chuck handle; The cubic hole dimension that the wrench body pallet is gone to the bottom matches with the size of four directions, chuck handle wrench body lower end spanner; After the wrench body of chuck handle inserts wrench body jack of the present utility model, the cubic spanner of wrench body lower end falls in the cubic hole that the wrench body pallet goes to the bottom and stretches out cubic hole and promotes elastic rocking beam and trigger and often open the microswitch closure.
During installation, the utility model positioningly is connected in to the appropriate location on lathe, the switching signal output of often driving microswitch is connected on the circuit of lathe power output shaft drive motors.
During use, using chuck handle after piece-holder is on chuck, because car is of the present utility model, often open on the circuit that the microswitch bed is connected in lathe power output shaft drive motors, chuck handle is taken off when just starting the lathe power output shaft and rotating from chuck having forgotten, lathe can not start, only have chuck handle is taken off from chuck, again the wrench body of chuck handle is inserted in wrench body jack of the present utility model, allow the cubic hole that the cubic spanner of wrench body lower end is gone to the bottom from the wrench body pallet stretch out, promote the elastic rocking beam triggering and often open the microswitch closure, could start the lathe power output shaft rotates.
The utility model can be connected in the switching signal output of often driving microswitch on the circuit of lathe power output shaft drive motors, when the wrench body of chuck handle inserts after wrench body jack of the present utility model internal trigger often drives microswitch and export closed switching signal, could start the lathe power output shaft and rotate.Can prevent with chuck handle after piece-holder is on chuck because forget, chuck handle is taken off and causes security incident from chuck.It is the safe homing device of a kind of lathe chuck spanner.
Below in conjunction with accompanying drawing, the utility model is further described.
