Description
Technical field
The utility model relates to a kind of metal-working plant, is specifically related to the safe lathe of a kind of metal cutting and control circuit thereof.
Background technology
When carrying out the turner operation, because new work is all to operate for the first time lathe, mood is more nervous, adds that engine lathe does not possess the automatic stopping protective device, in case by the operation of safe practice operational procedure, the security incident of the person and equipment just may occur.
Lathe incidental accident in new work mainly contains following a few place:
Chuck handle is hurted sb.'s feelings.New learn work with chuck handle clamping workpiece after on chuck; often such accident can occur: namely forget chuck handle is taken off with regard to the motor-car bed from chuck; chuck handle is along with the rotation of chuck lays to come and injure the hand of new work; in case such accident occurs; gently damage skin and flesh, heavy break finger.
Chuck in knife rest and rotation bumps against.In process, when slip crate during to left movement, learn newly that work is only noted the situation of processing sometimes and the accident that knife rest and chuck collide quite easily occurs for the position of having ignored knife rest.
And the reason that causes above-mentioned security incident to occur, be mainly because:
(1) the mood overstrain, attend to one thing and lose sight of another.New to learn work be all to touch for the first time lathe, and the lathe rotating speed is all higher, and some new trade union pretty nervous is worried to do bad, worries again own security incident is occuring, and just attends to one thing and lose sight of another when operating, and security incident easily occurs.
(2) operation is unskilled, and the master worker does half-hearted tin of when demonstration, there is no skillfully to grasp the hints on operation of lathe, add man-hour will be in a rush, security incident also easily occurs.
(3) by doing rules operations, before each workpiece processing, the master worker explains corresponding operational procedure, and demonstrates on lathe, but some new work always likes sticking to one's old way of doing things, and ignores operational procedure, thereby security incident occurs.
(4) absent-minded, energy disperses, and stand in for a long time lathe side processing work in addition, and thought can not concentrated, and energy disperses, and security incident also easily occurs.
The utility model content
The purpose of this utility model is to provide the safe lathe of a kind of metal cutting and control circuit thereof, solves the problem that now widely used lathe does not have to prevent that chuck handle from hurting sb.'s feelings and knife rest and chuck in rotating bump against.
For solving above-mentioned technical problem, the utility model is by the following technical solutions: the safe lathe of a kind of metal cutting, comprise the lathe main body and be arranged on the power switch box on the lathe main body, chuck and the knife rest of holding workpiece, and the chuck handle that is used for chuck installation or removal workpiece, be provided with the chuck handle controller in described power switch box, the middle part of power switch box is provided with the sleeve suitable with chuck handle, be provided with the normally opened contact of chuck handle controller in the bottom of sleeve, described normally opened contact is series in the lathe start-up circuit; Described knife rest is connected with synchronization-moving slip crate, there is a limit switch to be arranged on the track that knife rest advances, distance between described slip crate and limit switch is more than or equal to the distance between described chuck and knife rest, and the normally-closed contact of limit switch is series in the lathe start-up circuit.
Further technical scheme be above-mentioned sleeve opening direction vertically or obliquely.
The safe lathe control circuit of a kind of metal cutting, comprise hot relay safety control module and electric motor starting control module, wherein said electric motor starting control module comprises stop button normally-closed contact SB1, start button normally opened contact SB2, chuck handle controller normally opened contact SB3, limit switch normally-closed contact SQ and the contactor coil KA that mutually is connected in control circuit, and described start button normally opened contact SB2 and chuck handle controller normally opened contact SB3 are parallel with the normally opened contact KM of contactor coil KA.
Compared with prior art, the beneficial effects of the utility model are: utilize chuck handle to connect a normally opened contact in start-up circuit, prevented effectively that chuck handle from still staying and just started the danger that lathe brings on chuck; Utilize in addition slip crate can touch limit switch, knife rest touching chuck, prevented that effectively the chuck in knife rest and rotation from touching the danger that brings mutually one step ahead.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the safe lathe of the utility model metal cutting.
Fig. 2 is the enlarged diagram of power switch box in Fig. 1.
View when Fig. 3 is chuck handle insertion Fig. 2 middle sleeve.
Fig. 4 is the schematic diagram of an embodiment of the safe lathe control circuit of the utility model metal cutting.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Fig. 1, Fig. 2 and Fig. 3 show an embodiment of the safe lathe of the utility model metal cutting: the safe lathe of a kind of metal cutting, comprise lathe main body 1 and the power switch box 2 that is arranged on lathe main body 1, the chuck 4 of holding workpiece 3, knife rest 5, and the chuck handle 6 that is used for chuck 4 installation or removal workpiece 3, described power switch box 2 is provided with the chuck handle controller, the middle part of power switch box 2 is provided with the sleeve 8 suitable with chuck handle 6, be provided with the normally opened contact 9 of chuck handle controller in the bottom of sleeve 8, described normally opened contact 9 is series in the lathe start-up circuit, described knife rest 5 is connected with synchronization-moving slip crate 10, there is a limit switch 11 to be arranged on the track that knife rest 5 advances, distance between described slip crate 10 and limit switch 11 is more than or equal to the distance between described chuck 4 and knife rest 5, and the normally-closed contact of limit switch 11 is series in the lathe start-up circuit.
