Abstract

Provided is an air injection device for an air pressure chuck. A transverse spindle is arranged in a head seat body, and an air pressure chuck is combined at an end where the spindle extends out of the head seat body. Two abreast air injection ports are arranged on the outer periphery of the air pressure chuck, and a pressure cylinder is combined on a lateral face of the head seat body. The pressure cylinder combines with two abreast air blowing connectors through a support, and inner ends of the two air blowing connectors rightly face the two air injection ports. When the air pressure chuck is needed to be driven to perform loosing or clamping actions, rotating of the spindle is stopped and the two air injection ports are rotated to a position matched with the air blowing connectors firstly, then the pressing cylinder drives the two air blowing connectors to be connected with the two air injection ports so that operation of air injection is realized and accordingly the air pressure chuck is loosen or clamped, and finally the pressing cylinder drives the two air blowing connectors to retract and the operation is finished. The integral structure of the air injection device for the air pressure chuck is simple so that manufacture cost and installation time are saved.

One gas injection structure, lateral junction unification cylinder pressure at described headstock body, described cylinder pressure be positioned at described compressed air chuck around, the end of described cylinder pressure is towards described compressed air chuck and be provided with a body of rod, with the described body of rod in conjunction with a support, in conjunction with the two air blowing joints that are set up in parallel, the inner of two air blowing joints is over against two gas injection ports of described compressed air chuck at described support.
Further, the compressed air chuck surface of the utility model around on described each gas injection port top is arranged with a valve butting section, and each valve butting section is recessed arc surface; The bottom of the described joint of respectively blowing forms one respectively and connects mouth, and the bottom surface that respectively connects mouth is for cooperating the arc surface of each valve butting section.
Preferably, the mouth that connects of the described joint of respectively blowing of the present utility model is that the soft mouth that connects is constructed.
The utility model is that two air blowing joints are connected pneumatic supply with pipeline when using, when needs driving compressed air chuck is done to unclamp or is clamped action, earlier stop main axis rotation and two gas injection ports of compressed air chuck are rotated to the position that can cooperate two air blowing joints with the internal processes of board, then the cylinder pressure driving arm of gas injection structure moves towards the air pressure chuck, drive two gas injection ports that two air blowing joints connect compressed air chuck with support, the operation that can carry out gas injection this moment is unclamped compressed air chuck or is clamped, the gas injection back cylinder pressure that finishes drives two air blowing joints again and backs out, and can finish the operation that compressed air chuck is adjusted in the utility model gas injection.
The beneficial effects of the utility model are, owing to only utilize cylinder pressure can drive two gas injection ports that two air blowing joints connect compressed air chuck, therefore textural need not the domain the aluminium alloy distributing ring and the operation that the anti-rotation support can carry out gas injection, therefore can significantly save the time of production cost and installation, have economic benefit in the use and can reduce the cost that utilizes.

The specific embodiment
Following conjunction with figs. and preferred embodiment of the present utility model, further setting forth the utility model is to reach the technological means that predetermined utility model purpose is taked.
The utility model provides a kind of compressed air chuck gas injection device, as shown in Figure 1 and Figure 2, comprising:
One headstock 10, be provided with a headstock body 11, in headstock body 11, place a main shaft 12 with rotating form, be axis body along left and right direction horizontal expansion, the right flank of the right-hand member stretched head seat body 11 of main shaft 12, in the right part of main shaft 12 in conjunction with a compressed air chuck 13, be provided with two gas injection ports 131 at the top of compressed air chuck 13 outer peripheral faces, two gas injection ports 131 are provided with in forward and backward mode arranged side by side, compressed air chuck 13 surfaces around on each gas injection port 131 top are arranged with a valve butting section 132, and each valve butting section 132 is recessed arc surface.
One gas injection structure 20, at the right flank of headstock body 11 in conjunction with a cylinder pressure 21, can be pneumatic cylinder or oil hydraulic cylinder, cylinder pressure 21 is positioned at the top of compressed air chuck 13, be provided with the body of rod 211 that extends under one day in the bottom of cylinder pressure 21, with the body of rod 211 in conjunction with a support 22, support 22 forms an edge directly over two gas injection ports 131 before, the rear is to the flat part 221 that extends, at the flat part 221 of support 22 in conjunction with two air blowing joints 23, two air blowing joints 23 are the vertical blow head that is provided with and former, back mode at interval is set up in parallel, form one respectively in the bottom of each air blowing joint 23 and connect mouth 231, respectively connect mouth 231 for soft mouth structure and the bottom surface of connecing for cooperating the arc surface of each valve butting section 132, two air blowing joints 23 connect mouth 231 down over against two gas injection ports 131 of two compressed air chucks 13.
The utility model is that the top with two air blowing joints 23 of gas injection structure 20 connects pneumatic supply with pipeline when using, when needs driving compressed air chuck 13 is done to unclamp or is clamped action, as Fig. 3, shown in Figure 4, stop main shaft 12 rotation earlier and two gas injection ports 131 of compressed air chuck 13 are rotated to the top position that can cooperate two air blowing joints 23, then the cylinder pressure 21 of gas injection structure 20 extends the body of rod 211 down, driving two air blowing joints 23 with support 22 descends, this moment, two air blowing joints 23 were resisted against valve butting section 132 with the bottom surface that connects mouth 231, reach airtight effect and connect two gas injection ports, the operation that can carry out gas injection this moment is unclamped compressed air chuck 13 or is clamped, and the back cylinder pressure 21 that finishes drives two air blowing joints 23 and backs out the operation of promptly finishing gas injection adjustment compressed air chuck 13 up.
Because two gas injection ports 131 that the utility model utilizes cylinder pressure 21 can drive two air blowing joints, 23 connection compressed air chucks 13 carry out the operation of gas injection, the structure of gas injection structure 20 only has the combination of cylinder pressure 21, support 22 and two air blowing joints 23, need not to be provided with the aluminium alloy distributing ring and the anti-rotation support of the domain, therefore can save the time of production cost and installation exercise, have economic benefit in the use and can reduce the cost that utilizes.
The above only is a preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in the scope that does not break away from technical solutions of the utility model, should utilize the technology contents of above-mentioned announcement to make a little change or be modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
