Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; This back distribution type front pneumatic chuck is linked to be an integral body with cylinder body and chuck, distributing valve is rearmounted separately, can on the narrow and small equipment of some lathe trailing space, install smoothly, can reduce labor intensity greatly, shorten clamping time, boost productivity, and clamping force can adjust, be fit to needs in the distribution of lathe afterbody, the limited numerical control device of trailing space is supporting simultaneously.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1, comprise chuck body 1, wedge-catch system 2, door 3, three claws 4, three slides 5, three T type pieces 6, push-and-pull cover 7, push-and-pull ring 8, cylinder block 9, piston 10, base 11, the axis of guide 12, valve rod 13, valve body 14, valve gap 15, bearing 16 ~ 17, first sealing ring 18, second sealing ring 19, the 3rd sealing ring 20, the 4th sealing ring 21, the 5th sealing ring 22.
The utility model connects chuck body 1, door 3 and forms chuck main body, offer three straight troughs at chuck body 1 front end, article three, three slides 5 are installed in the straight trough, three slides 5 connect with wedge-catch system 2 by skewed slot, three slides 5 are connected with three claws 4 by broach outside the disk body front end face, and fixing by six T type pieces 6 and three claws 4, and connect with wedge-catch system 2 with the claw mounting screw.Cylinder block 9, base 11 are formed the cylinder main body, and piston 10 is installed in the cylinder block 9, and slides in cylinder block 9 along the axis of guide 12 directions.Piston 10 links to each other by push-and-pull cover 7, push-and-pull ring 8 with wedge-catch system 2, and under the drive of piston 10, wedge-catch system 2 can slide up and down in chuck body 1.Wedge-catch system 2 is provided with skewed slot at front end and three slide 5 contact positions, and sliding in the front and back of wedge-catch system 2 to convert moving radially of claw 4 to.
Lower air chamber in the formation up and down of piston 10, the control gas of last lower air chamber is by the air inlet/outlet control that is provided with on the valve body 14 of postposition.Base 11 and lengthening valve rod 13 screw with screw thread and form a fixed connection, and link to each other by two bearings 16,17 between lengthening valve rod 13 and the valve body 14 and can realize rotation relatively at a high speed, and valve gap 15 is connected with valve body 14 by screw.
Described chuck body 1 is realized seamless being fixedly connected with cylinder block 9 usefulness joint bolts, is provided with 22 sealings of the 5th sealing ring between cylinder block 9 and the base 11; Be provided with the 3rd sealing ring 20,21 sealings of the 4th sealing ring between described cylinder block 9 and the piston 10; Be provided with first sealing ring 18,19 sealings of second sealing ring between described base 11 and the lengthening valve rod 13.
The utility model operation principle:
The utility model revolution cylinder is divided into two parts, and a part forms the bigger forward type cylinder of volume by parts such as cylinder block, base and pistons and chuck body is realized seamless being fixedly connected with joint bolt, is installed on spindle head machine; Another part becomes the less distributing valve system of volume by valve rod, valve body, valve gap and bearing group, realizes that by the shaft length lengthening distributing valve is in lathe afterbody postposition.
Clamping workpiece is convenient, revolution flexibly, be fit to needs in the distribution of lathe afterbody, the limited numerical control device of trailing space is supporting simultaneously.The utility model gas enters the air inlet pipeline of valve rod from the air admission hole on the valve body, thereby lead to the cylinder epicoele, promote piston and drive wedge-catch system to move down, by the skewed slot on the wedge-catch system slide is produced together with claw again and clamp motion, the gas of cylinder cavity of resorption is then discharged from venthole.On the contrary, when gas when venthole one tunnel enters the cylinder cavity of resorption, piston moves up and claw is unclamped.
