Abstract
The utility model discloses a kind of lathe finger protective door, comprise move to left door and the door that moves to right, the described door that moves to left is arranged on left protective cover actively, the described door that moves to right is arranged on right protective cover actively, the described door and move to right door by air cylinder driven of moving to left, the described door that moves to left is provided with infrared transmitting tube, the described door that moves to right is provided with infrared receiving tube, described infrared receiving tube is electrically connected with PLC master chip, described PLC master chip electrical connection magnetic valve, described magnetic valve is for controlling to the break-make of the gas circuit of cylinder air feed.The utility model is by being provided with infrared transmitting tube and infrared receiving tube, when having any part of human body to be in move to left door and moving to right between door, the infrared ray that infrared transmitting tube is launched is stopped, the signal of infrared receiving tube changes, therefore PLC sends signal disconnects gas circuit to magnetic valve, when infrared ray is unobstructed, just recover gas circuit.
Description
Technical field
The utility model relates to a kind of lathe, particularly relates to a kind of lathe finger protective door.
Background technology
Vertical machining centre is the intelligent lathe of numerically controlled mechanical-electrical-hydraulic integration.Its structure is made up of parts such as main frame, control system, outer protective cover, tool magazine, water tanks.In process, usually pre-configured cooling fluid is needed to carry out strengthening spraying cooling to workpiece man-hour adding, in process, cutting fluid is easily splashed simultaneously, have man-hour operator to be strayed into will to cause great security incident if rotate lathe adding simultaneously, therefore existing lathe or machining center are mostly provided with protective door.
Such as CN 101837556 A discloses a kind of Pneumatic control double door protective device, comprises and moves left door and move right door and the door glass on door; Also comprise: the left cover of full protection and the right cover of full protection; Move left door and an inner side being placed in the left cover of full protection and the right cover of full protection respectively that moves right; Moving left door is placed on lower door track and upper guided way with the upper and lower both sides of the door that moves right respectively; One end of left and right pull bar respectively with move left the upper end of door with the door that moves right and be connected; The other end of left and right pull bar and rod-pulling type cylinders; Rod-pulling type cylinder is connected with a controller controlling this rod-pulling type cylinder.Although this device can play protective action, if having the arm of operator at closing time also in the scope of closing the door, then easily crush the arm of human body by mistake, improve above-mentioned protective door so need badly.
Utility model content
The purpose of this utility model is to solve technical problem involved in background technology, providing a kind of lathe finger protective door.
The technical solution of the utility model is: a kind of lathe finger protective door, comprise move to left door and the door that moves to right, the described door that moves to left is arranged on left protective cover actively, the described door that moves to right is arranged on right protective cover actively, the described door and move to right door by air cylinder driven of moving to left, the described door that moves to left is provided with infrared transmitting tube, the described door that moves to right is provided with infrared receiving tube, described infrared receiving tube is electrically connected with PLC master chip, described PLC master chip electrical connection magnetic valve, described magnetic valve is for controlling to the break-make of the gas circuit of cylinder air feed.
Preferred as one, described in move to left on door and the door that moves to right and be provided with pulley, described pulley moves on left protective cover and right protective cover.
Preferred as one, described cylinder is provided with cylinder body and piston rod, and described cylinder body static connection is on left protective cover or right protective cover, and described piston rod is used for promotion and moves to left door and the door that moves to right.
In sum, the utility model has following advantage:
The utility model is by being provided with infrared transmitting tube and infrared receiving tube, when having any part of human body to be in move to left door and moving to right between door, the infrared ray that infrared transmitting tube is launched is stopped, the signal of infrared receiving tube changes, therefore PLC sends signal disconnects gas circuit to magnetic valve, when infrared ray is unobstructed, just recover gas circuit.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present utility model.
Detailed description of the invention
As shown in Figure 1,1, a kind of lathe finger protective door, comprise move to left door 1 and the door 2 that moves to right, the described door 1 that moves to left is arranged on left protective cover 3 actively, the described door 2 that moves to right is arranged on right protective cover 4 actively, the described door 1 that moves to left is driven by cylinder 7 with the door 2 that moves to right, the described door 1 that moves to left is provided with infrared transmitting tube 5, the described door 2 that moves to right is provided with infrared receiving tube 6, described infrared receiving tube 6 is electrically connected with PLC master chip, described PLC master chip electrical connection magnetic valve, described magnetic valve is for controlling to the break-make of the gas circuit of cylinder 7 air feed.Described move to left door 1 and the door 2 that moves to right are provided with pulley 8, and described pulley 8 moves on left protective cover 3 and right protective cover 4.Described cylinder 7 is provided with cylinder body 71 and piston rod 72, and the static connection of described cylinder body 71 is on left protective cover 3 or right protective cover 4, and described piston rod 72 is for promoting move to left door 1 and the door 2 that moves to right.Described infrared transmitting tube 5 is LED transmitting tube, and emission angle is 90-160 °.
More than illustrate it is only to explanation of the present utility model, those of ordinary skill in the art's can completely is made to implement this programme, but be not to restriction of the present utility model, those skilled in the art can make to the present embodiment the amendment not having creative contribution as required after reading this description, and these are all not creative amendments.As long as but be all subject to the protection of Patent Law in right of the present utility model.
