Abstract
The utility model relates to a front-located air chuck, which is characterized in that a chuck main body is formed by connecting a chuck body, a cylinder cover, a retaining cover and a spacing disc, wherein a flange is fixedly connected with the cylinder cover through a flange connection bolt, the front end of the chuck body is provided with a retaining valve, the front end of the chuck body is provided with a groove, a slide seat is installed inside the groove, a T-shaped block and a jaw are installed on the slide seat through a jaw mounting bolt, and a piston is installed inside the chuck body and is connected with a wedge catch system. The front-located air chuck is characterized in that a distributing ring is arranged on the rear part of the chuck body, a sealing ring is arranged between the distributing ring and the chuck body to seal, and the upper part of the distributing ring is provided with a first pipe joint and a second pipe joint. The wedge catch system is provided with achute. The front-located air chuck is used for joining the cylinder body and the chuck into a whole body to be installed on the head part of a main shaft, and the front-located air chuck is provided with a large through hole which can be used for a long rod material to pass, so the chuck is mainly used for clamping a long pipe, and can greatly reduce the labor intensity, shorten the clamping timeand can improve the productivity; moreover, the clamping force is adjustable, and the front-located air chuck is matched with numerically-controlled lathe and is an excellent device for processing thelong pipes.
Description
Technical field
The utility model relates to a kind of front-mounted pneumatic chuck, specifically is used for matching with numerically controlled lathe, and cylinder body and chuck are linked to be an integral body, belongs to the machine tool accessories technical field.
Background technology
In prior art, comparatively close with the utility model 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 purpose of this utility model is to overcome above-mentioned weak point, is used for clamping long tube thereby provide a kind of by long bar, can reduce labor intensity greatly, shortens clamping time, and the front-mounted pneumatic chuck that can enhance productivity.
The technical scheme that provides according to the utility model, 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 utility model has the following advantages:
The utility model 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 the utility model construction profile figure.
Fig. 2 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 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.
The utility model operation principle:
This forward type chuck of the utility model 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.The utility model 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.
