Abstract
The invention relates to a front-mounted pneumatic chuck which mainly comprises a chuck main body formed by connecting a chuck body, a cylinder cover, a block cover and a separation disc, wherein a flange is fixedly connected with the cylinder cover by flange connecting bolts, a one-way valve is arranged at the front end of the chuck body, a groove is disposed at the front end of the chuck body and is internally provided with a slide carriage, a T-shaped block and a jack catch are arranged on the slide carriage by jack catch mounting bolts, and a piston is arranged in the chuck body and is connected with a wedge sleeve. The front-mounted pneumatic chuck is characterized in that the rear part of the chuck body is provided with a distributing ring, the distributing ring and the chuck body are sealed by a seal ring, and the upper part of the distributing ring is provided with a first tube connector and a second tube connector; and the wedge sleeve is provided with a gravity plane. The front-mounted pneumatic chuck is used for connecting a cylinder body and the chuck into a whole, is arranged at the head part of a main shaft and is provided with a large through hole at the middle for long barstocks to pass through, therefore, the front-mounted pneumatic chuck is mainly used for clamping long tubes, can greatly reduce labor intensity, shortens long tube clamping time, improves production efficiency, has adjustable clamping force, is matched with a numerically-controlled lathe and is the most excellent equipment for processing long tubes.
Description
Technical field
The present invention relates to a kind of front-mounted pneumatic chuck, specifically be used for matching, cylinder body and chuck are linked to be an integral body, belong to the machine tool accessories technical field with numerically controlled lathe.
Background technology
In prior art, comparatively close with the present invention is power chuck and rotary cylinder system.Common pneumatic (or surging) chuck is contained in spindle nose, and cylinder (or oil cylinder) is contained in afterbody, and the two couples together with pull bar, by moving axially of piston chuck jaws is produced and moves radially, with pine folder workpiece.Because the existence of pull bar can not pass through bigger long tube, so can only clamping disk(-sc) class and stub class part.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, be used for clamping long tube by long bar, can reduce labor intensity greatly, shorten clamping time thereby provide a kind of, and the front-mounted pneumatic chuck that can enhance productivity.
According to technical scheme provided by the invention, front-mounted pneumatic chuck is by chuck body, cylinder cap, door reaches every dish and connects the composition chuck main body, ring flange is fixedly connected with ring flange joint bolt and cylinder cap, at the chuck body front end check valve is installed, offer three grooves at the chuck body front end, article three, three slides are installed respectively in the groove, on three slides, fix by three T type pieces and three claws with the claw mounting screw, feature is: piston is installed in the chuck body, and connect with wedge-catch system, distributing ring is equipped with at described chuck body rear portion, by seal ring seal, the first pipe joint A and the second pipe joint B is installed on distributing ring top between distributing ring and the chuck body.
The center of the piston in the described chuck body, wedge-catch system and cylinder cap is provided with larger-diameter through hole, can be by large diameter workpiece such as steel pipe etc. when making chucking work.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; This forward type chuck is used for cylinder body and chuck are linked to be an integral body, be contained in spindle nose, in the middle of large through-hole is arranged, can pass through long bar, so this chuck is mainly used in clamping long tube, can reduce labor intensity greatly, shorten clamping time, boost productivity, and clamping force can be adjusted, matching with numerically controlled lathe, is the best equipment of processing long tube.
Description of drawings
Fig. 1 is construction profile figure of the present invention.
Fig. 2 is a structural representation of the present invention.
The specific embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 2, comprise ring flange 1, cylinder cap 2, piston 3, distributing ring 4, every dish 5, chuck body 6, check valve 7, wedge-catch system 8, door 9, three claws 10, claw mounting screw 11, three T type pieces 12, three slides 13, sealing ring 14, ring flange joint bolt 15 etc.
With chuck body 6, cylinder cap 2, door 9 reaches every dish 5 and connects the composition chuck main bodies, ring flange 1 usefulness ring flange joint bolt 15 is fixedly connected with cylinder cap 2, in order to be contained in spindle head machine, at chuck body 6 rear portions distributing ring 4 is housed, seal by sealing ring 14 between distributing ring 4 and the chuck body 6, the first pipe joint A and the second pipe joint B are installed on distributing ring 4 tops, at chuck body 6 front ends check valve 7 is installed, offer three grooves at chuck body 6 front ends, article three, three slides 13 are installed in the groove, fixing with claw mounting screw 11 on three slides 13 by three T type pieces 12 and three claws 10, piston 3 is installed in the chuck body 6, and connect with wedge-catch system 8, piston 3 and wedge-catch system 8 can horizontally slip in chuck body 6, and wedge-catch system 8 is provided with skewed slot at front end and three slide 13 contact positions, and sliding in the front and back of piston 3 to convert moving radially of claw 10 to, form left and right sides air cavity about piston 3, the control gas of left and right sides air cavity is to be controlled by check valve 7 by the first pipe joint A and the second pipe joint B.
The center of the piston 3 in the described chuck body 6, wedge-catch system 8 and cylinder cap 2 is provided with larger-diameter through hole, can be by large diameter workpiece such as steel pipe etc. when making chucking work.
Operation principle of the present invention:
This forward type chuck is used for cylinder body and chuck body are linked to be an integral body, is contained in spindle nose, and large through-hole is arranged in the middle of the chuck, can pass through larger-diameter part, matches with numerically controlled lathe.Compressed air enters the check valve left side from the first pipe joint A on the distributing ring, push spool open and enter the right chamber of cylinder, promote piston and drive wedge-catch system to move backward, by the skewed slot on the wedge-catch system slide is produced together with claw again and clamp motion, the air in chamber, a cylinder left side is then discharged from the right side of check valve.When compressed air when the second pipe joint B enters, enter chamber, a cylinder left side by the check valve right side, piston forward moves and claw is unclamped.
