Abstract
The utility model relates to a lathe chuck safety starting drive with protection casing belongs to the electromechanical control field. The utility model discloses can avoid the chuck wrench who loses on the lathe chuck to be thrown away and hurt lathe operator and the condition emergence of equipment on every side, have simple structure, characteristics with low costs. The utility model discloses by headstock, protection casing, normally closed switch, stop screw with take cap round pin axle to constitute, the protection casing cup joints is taking the cap to sell epaxial to but strip winding cap round pin axle rotates, takes cap pivort fixation on the headstock, the normally closed switch is fixed on the headstock among the control circuit of the drive lathe chuck motor and the normally closed switch puts in series, stop screw fixes on the headstock.
Description
Technical field
This utility model relates to a kind of lathe chuck safety starting device with protective cover, belongs to electromechanical control field.
Background technology
At present; from known engine lathe and lathe in machining operating process; latheman often occurs chuck handle is lost the situation falling within lathe chuck; if at this moment starting lathe chuck; chuck handle can be thrown out of under the influence of centrifugal force, and machine operation person and surrounding devices are damaged.
Summary of the invention
Injure the deficiency of machine operation person and surrounding devices to overcome the chuck handle that in existing lathe operation process, something lost falls within lathe chuck to be thrown out of, this utility model provides a kind of lathe chuck safety starting device with protective cover.This utility model solves its technical problem and be the technical scheme is that by headstock, protective cover, normally closed switch, stop screw and form a kind of lathe chuck safety starting device with protective cover with cap bearing pin.Shielding cover is connected on band cap bearing pin, and can rotate around band cap bearing pin, and band cap bearing pin is fixed on headstock.Normally closed switch is fixed on headstock and in the control circuit of normally closed switch series connection access lathe chuck motor, is to turn on state under normally closed switch normal condition.Stop screw is fixed on headstock, is used for limiting location when protective cover is opened.
The beneficial effects of the utility model are: when protective cover is closed, now protective cover contacts with stop screw, and normally closed switch is in normal condition, and normally closed switch is to turn on, and pressing lathe chuck when lathe chuck starts button can normally start；When falling within lathe chuck when there being chuck handle to lose, protective cover is opened, now protective cover contacts with the movable contact of normally closed switch, normally closed switch is made to disconnect, owing to normally closed switch is in the control circuit that series connection accesses lathe chuck motor, therefore lathe chuck electromotor control circuit is open circuit, start button lathe chuck still can not start even if now pressing lathe chuck, such that it is able to avoid losing the chuck handle falling within lathe chuck is thrown out of and the situation of machine operation person and surrounding devices of injuring occurs.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the outside drawing of a kind of lathe chuck safety starting device with protective cover；
Fig. 2 is the side view of a kind of lathe chuck safety starting device with protective cover.
1. headstock in figure, 2. protective cover, 3. normally closed switch, 4. stop screw, 5. band cap bearing pin, 6. chuck.
Detailed description of the invention
With reference to Fig. 1, by headstock 1, protective cover 2, normally closed switch 3, stop screw 4 with form a kind of lathe chuck safety starting device with protective cover with cap bearing pin 5.Protective cover 2 is socketed on band cap bearing pin 5, and can rotate around band cap bearing pin 5, and band cap bearing pin 5 is fixed on headstock 1.Normally closed switch 3 is fixed on headstock 1 and normally closed switch 3 is connected in the control circuit accessing the motor driving chuck 6.Stop screw 4 is fixed on headstock 1.With reference to Fig. 1, when protective cover 2 is closed, now protective cover 2 contacts with stop screw 4, and normally closed switch 3 is to turn on, and chuck 6 can normally start.With reference to Fig. 2, when falling within chuck 6 when there being chuck handle to lose, protective cover 2 is opened, now protective cover 2 contacts with the movable contact of normally closed switch 3, making normally closed switch 3 disconnect, owing to normally closed switch 3 is in the control circuit that series connection accesses the motor driving chuck 6, therefore the electromotor control circuit of driving chuck 6 is open circuit, now chuck 6 can not start, it is possible to avoids losing the chuck handle falling within lathe chuck and is thrown out of and injures machine operation person and surrounding devices.
