Abstract
The utility model discloses a device enabling a machine tool chuck wrench to control the opening of a machine tool. The device is composed of the machine tool chuck wrench, connecting through holes, a base plate, a shaft sleeve, screws, a travel switch, an indicator light, an indicator light seat, wires and a main motor control box. After the machine tool chuck wrench clamps or loosens a workpiece, only when the machine tool chuck wrench is placed into the shaft sleeve of the device can the machine tool be opened, and therefore safety accidents caused by misuse of the chuck wrench are avoided.
Description
Technical field
The utility model relates to machine tool chuck wrench use secure context problem in mechanical processing process, can prevent the generation of machine operation security incident, has improved the security performance of lathe.
Background technology
Lathe is equipment the most frequently used in mechanical processing process, and security incident often occurs in the lathe start-up course.Modal security incident be on machine chuck with the chuck handle clamping, when unclamping workpiece, chuck handle is untimely takes off from chuck, if after starting lathe, chuck rotates, spanner throws away by tangential direction, easily hurts sb.'s feelings or hinders thing; Perhaps spanner can not in time throw away and block the damage lathe, and these situations often occur when machining training for beginner or student.Based on above-mentioned situation, design a kind of device, be arranged on lathe, can avoid the security incident that causes because of the chuck handle improper use.
Summary of the invention
The purpose of this utility model is to provide a kind of machine tool chuck wrench and controls the device that lathe is opened.When the machine tool chuck wrench clamping or after unclamping workpiece, machine tool chuck wrench is put into the axle sleeve of this device, could start lathe, avoid the security incident that causes because of the chuck handle improper use.
The technical solution adopted in the utility model is: it is comprised of chuck handle (1), connecting through hole (2), base plate (3), axle sleeve (4), screw (5), travel switch (6), indicator lamp (7), pilot bracket (8), electric wire (9) and main motor control box (10).The electric line of this device is connected with lathe master Electric Machine Control electric line, when chuck handle (1) is worked on chuck, travel switch (6) contact top does not have bearing pressure, contact stretches out, travel switch (6) is in off state, lathe master motor circuit is in off state, and lathe can not be worked, and chuck can not rotate; Take out from the chuck small square hole when chuck handle (1) be put in axle sleeve (4) after, the lower surface of chuck handle (1) and travel switch (6) contact top contacts, travel switch (6) contact bears the pressure of chuck handle (1) and presses down contraction, when closing the lathe power supply, the bright power on signal that sends of indicator lamp (7), lathe can start starts working.
The beneficial effects of the utility model are: put into axle sleeve (4) after using chuck handle (1), could start lathe, avoid the security incident that causes because of the chuck handle improper use.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model
In Fig. 1,1, chuck handle; 2, connecting through hole; 3, base plate; 4, axle sleeve; 5, screw; 6, travel switch; 7, indicator lamp; 8, pilot bracket; 9, electric wire; 10, main motor control box.
The specific embodiment
The utility model is comprised of chuck handle (1), connecting through hole (2), base plate (3), axle sleeve (4), screw (5), travel switch (6), indicator lamp (7), pilot bracket (8), electric wire (9) and main motor control box (10).be welded and fixed axle sleeve (4) on base plate (3), by 4 screws (5), travel switch (6) is fixed on base plate (3) below axle sleeve (4), the contact of travel switch (6) stretches in axle sleeve (4), fix indicator lamp holder (8) and indicator lamp (7) is installed on base plate (3), join according to the connecting through hole (2) on base plate (3) in the positive smooth position of lathe (lathe left side) and make 4 screwed holes of processing, again base plate (3) is installed to relevant position on lathe by 4 screws, be connected at last travel switch (6), indicator lamp (7), electric wire (9) between main motor control box (10), should note during work: 1, can not insert other thing except chuck handle (1) in axle sleeve (4) hole.2, chuck handle (1) should be inserted into axle sleeve (4) hole indicating lamp (7) and could start lathe after bright.
Claims (1)
1. a machine tool chuck wrench is controlled the device that lathe is opened, and it is comprised of chuck handle, connecting through hole, base plate, axle sleeve, screw, travel switch, indicator lamp, pilot bracket, electric wire and main motor control box; The electric line that it is characterized in that this device is connected with lathe master Electric Machine Control electric line, when chuck handle is worked on chuck, travel switch contact top does not have bearing pressure, contact stretches out, travel switch is in off state, lathe master motor circuit is in off state, and lathe can not be worked, and chuck can not rotate; Take out from the chuck small square hole when chuck handle be put in axle sleeve after, the lower surface of chuck handle and travel switch contact top contacts, the travel switch contact bears the pressure of chuck handle and presses down contraction, when closing the lathe power supply, the bright power on signal that sends of indicator lamp, lathe can start starts working.
