Abstract
The utility model relates to a safety protection device for a lathe chuck wrench. The safety protection device for the lathe chuck wrench is characterized by comprising a swinging block and a microswitch. The swinging block is axially positioned on a lathe body of the outer rotating edge of a chuck. A long rod is fixedly arranged on the swinging block and extends out towards the outer edge of the chuck. The long rod can be touched by the chuck wrench inserted on the chuck, but normal clamping of a workpiece is not affected. A reset spring is arranged between the swinging block and the lathe body. The microswitch is installed on the lathe body and located behind the position where the swinging block moves. The microswitch can be touched by the swinging block which anticlockwise moves to be turned on. Joint control over the microswitch and a lathe power source switch is achieved. The microswitch is touched, the joint control relation of turn-on and turn-off of a lathe power source is achieved, the lathe is forced to stop urgently within the short time period after the chuck just starts to rotate, protective actions are achieved, potential safety hazards are eliminated, and the safety protection device can be used as afterward protective measures.
Description
Technical field:
The utility model relates to a kind of lathe chuck spanner safety device, is particularly suited for engine lathe improvement, improves processing safety.
Background technology:
In the time carrying out the skills practice training of engine lathe, the workman who begins to learn or student, after clamping finished piece(s), often because anxiety has been forgotten to take off chuck handle and just directly started lathe, fly out and hurt sb.'s feelings or the accident of damage equipment thereby there is chuck handle.For avoiding this accident potential, there are at present many protectors to occur, although but these protectors have played protective effect in the time of real training, but because the engine lathe in enterprise may not be equipped with the protector of this class, thereby with this lathe real training that is equipped with special protector workman or student out, in the time that enterprise practical operates, easily accidents happened all the better, because they can not take the safety problem of chuck handle completely into account in the time of real training, practice training centre with these many universities and colleges of undergraduate course is produced reality in order to be more close to, abandon one after another this type of protector.For this reason, be necessary existing engine lathe to do suitable improvement, increase safety device, to be connected real training and actual working environment.
Summary of the invention:
The purpose of this utility model is on a kind of lathe bed that rotates outer at chuck of design, the microswitch that can be touched by chuck handle is set, the lathe chuck spanner safety device of Synchronization Control lathe power supply.
Technical solutions of the utility model are achieved in that a kind of lathe chuck spanner safety device, it is characterized in that this device comprises swinging block and microswitch; Described swinging block axle is positioned on the lathe bed of chuck rotation outer, on swinging block, be fixed with a stock, this stock extends to chuck outer, and the chuck handle that can be plugged on chuck touches, but do not affect normal clamping workpiece, between swinging block and lathe bed, be also provided with back-moving spring; Described microswitch is arranged on the rear in swinging block motion on lathe bed, and the swinging block that can be moved counterclockwise touches and connects, microswitch and lathe power switch joint control.Realize microswitch contact, and the joint control relation of lathe power remove forces lathe suddenly to stop.
Described stock is the flexible rod member of elasticity.
Described swinging block and microswitch are arranged on an installing plate, and installing plate utilizes screw directly to lock on lathe bed.
The protector of the utility model design; one safeguard procedures afterwards; that is to say at chuck handle and forgotten to take off; and a kind of scram protection device after startup lathe; by mechanical part start rotation at lathe main electric motor starting, chuck, chuck handle also fails just to touch microswitch in the very fast utmost point short time flying out, and cut off the electricity supply by electrical control lathe again, forces that lathe is anxious to stop; realize protection action, eliminate safe hidden trouble.
Accompanying drawing explanation:
Below in conjunction with concrete legend, the utility model is described further:
Fig. 1 lathe partial front elevation view
Fig. 2 lathe partial side view
Wherein
1-swinging block, 11-stock, 12-back-moving spring, 2-microswitch
3-installing plate, 4-screw, 5-lathe bed, 51-chuck
6-chuck handle
The specific embodiment:
See figures.1.and.2, lathe chuck spanner safety device, this device comprises swinging block 1 and microswitch 2, and both are arranged on an installing plate 3, and installing plate 3 utilizes screw 4 directly to lock on lathe bed 5, facilitates the safety of protector;
Described swinging block 1 axle is positioned on the lathe bed 5 that chuck 51 rotates outer, says that exactly swinging block 1 axle is positioned on installing plate 3, and recycling installing plate 3 is arranged on lathe bed 5, and its position rotates on outer in chuck 51; On swinging block 1, be fixed with a stock 11, this stock 11 extends to chuck 51 outers, and the chuck handle 6 that can be plugged on chuck 51 touches, and drives swinging block 1 rotation to touch microswitch 2; For this reason, need between swinging block 1 and lathe bed 5, be provided with back-moving spring 12, to pull away after chuck handle 6, swinging block 1 can reset; In fact one end of described back-moving spring 12 is to be also fixed on installing plate 3; In addition; stock 11 is the flexible rod member of elasticity; in the time that chuck handle 6 touches stock 11; when stock 11 drives swinging block 1 to turn to extreme position; by the bending of stock 11, allow chuck 51 under effect of inertia, continue unpowered rotation; thereby protective device is not damaged, and can trigger microswitch 2.The rear that microswitch 2 moves in swinging block 1, the swinging block 1 that can be moved counterclockwise touches and connects, microswitch 2 and lathe power switch joint control, once be also that microswitch 2 is connected, the joint control mode of cutting-off lathe power supply immediately.
