The bidirectional pressure maintaining pre-pneumatic chuck disclosed by the invention has the advantages of simple, compact and reasonable structure, more flexible use and wider use range, is assorted with a numerically controlled lathe and is the best equipment for processing pipe-type parts, and the pressure maintaining direction can be determined at will.
Description
Technical field
The present invention relates to a kind of two-way pressurize front-mounted pneumatic chuck, specifically be used for matching with numerically controlled lathe, pressurize cylinder and chuck are linked to be an integral body, belong to the machine tool accessories technical field.
Background technology
In prior art, common front-mounted pneumatic chuck system that comparatively close with the present invention is.Common front-mounted pneumatic chuck is contained in spindle nose, can only realize one-way pressure maintaining, so can only clamp or the stretching part, has in the use certain limitation.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, can arbitrarily determine to clamp or stretching thereby provide a kind of, be used for clamping or stretching long tube, can greatly reduce labor intensity, shorten the clamping workpiece time, and the two-way pressurize front-mounted pneumatic chuck that can enhance productivity.
According to technical scheme provided by the invention, two-way pressurize front-mounted pneumatic chuck comprises chuck body, wedge-catch system, door, cylinder cap, piston, three slides, T-shaped, three claws and two groups of check valves; Described chuck body, cylinder cap and door connect and form chuck main body, be fixedly connected with joint bolt and cylinder cap by ring flange, in order to be contained in spindle head machine, offer three grooves at the chuck body front end, article three, three slides are installed in the groove, on three slides, fix by three T-shaped and three claws with mounting screw, at the chuck body front end two groups of check valves are installed respectively, described piston is installed in the chuck body, and connect with wedge-catch system, piston and wedge-catch system can horizontally slip in chuck body, form left and right sides cylinder chamber about piston, two groups of check valves pass through respectively tracheae, joint is connected with left and right sides cylinder chamber, can realize the respectively pressurize of chamber, cylinder front and back.
As a further improvement on the present invention, described wedge-catch system front end and three slide contact positions are provided with skewed slot, and sliding in the front and back of piston to convert moving radially of claw to.
As a further improvement on the present invention, distributing ring is equipped with at described chuck body rear portion, and the first pipe joint and the second pipe joint are installed on distributing ring top; The control gas of left and right sides cylinder chamber is to be controlled by two groups of check valves by the first pipe joint and the second pipe joint.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Former forward type chuck just must be determined pressure-maintaining direction before production, can only be used for single clamping or stretching workpiece; Two-way pressurize front-mounted pneumatic chuck can arbitrarily be determined pressure-maintaining direction, uses more flexibly, and range of application is more extensive, matches with numerically controlled lathe, is the best equipment of processing pipe part.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is structure cutaway view of the present invention.
The specific embodiment
Following the present invention is further described in connection with the embodiment in the accompanying drawing:
As shown in Figure 2, comprise chuck body 1, wedge-catch system 2, door 3, distributing ring 4, cylinder cap 5, piston 6, three slides 7, T-shaped 8, three claw 9, two groups of check valves 10, the first pipe joint 11 and second pipe joints 12 etc.
The present invention is with chuck body 1, cylinder cap 5, door 3 connects and forms chuck main body, be fixedly connected with joint bolt and cylinder cap 5 by ring flange, in order to be contained in spindle head machine, at chuck body 1 rear portion distributing ring 4 is housed, the first pipe joint 11 and the second pipe joint 12 are installed on distributing ring 4 tops, at chuck body 1 front end two groups of check valves 10 are installed, offer three grooves at chuck body 1 front end, article three, three slides 7 are installed in the groove, fixing by three T-shaped 8 and three claws 9 with mounting screw on three slides 7, piston 6 is installed in the chuck body 1, and connect with wedge-catch system 2, piston 6 and wedge-catch system 2 can horizontally slip in chuck body 1, wedge-catch system 2 is provided with skewed slot at front end and three slide 7 contact positions, and sliding in the front and back of piston 6 to convert moving radially of claw 9 to, forms left and right sides cylinder chamber about piston 6, two groups of check valves 10 pass through respectively tracheae, joint is connected with left and right sides cylinder chamber, realizes the respectively pressurize of chamber, cylinder front and back.The control gas of left and right sides air cavity is to be controlled by two groups of check valves 10 by the first pipe joint 11 and the second pipe joint 12.
Operation principle of the present invention:
This forward type chuck of the present invention is used for cylinder body and chuck 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 of the present invention enters first group of check valve from the first pipe joint 11 on the distributing ring, push spool open and enter the right chamber of cylinder, pushing piston and to drive wedge-catch system mobile backward, by the skewed slot on the wedge-catch system slide is produced together with claw again and clamp motion, the air in the left chamber of cylinder is then discharged from second group of check valve.When compressed air enters from the second pipe joint 12, enter the left chamber of cylinder by second group of check valve, the air in the right chamber of cylinder is then discharged from first group of check valve, and piston forward moves and claw is unclamped.
