Abstract
The utility model relates to an improved three-jaw chuck and belongs to the technical field of machining fixtures. On the basis of cited reference, a three-jaw chuck is improved, mainly, an inner hole cutter and a power device for restoration of clamping jaws of the chuck are additionally arranged on the original basis, and the power device comprises an air cylinder, a retractable rod and a motor; the inner hole cutter is arranged on a center shaft of the chuck, and the power device is arranged on the back face of the chuck; the inner hole cutter is connected with the motor through a connector; the motor is supported by a supporting frame and connected with the retractable rod; the other side of the retractable rod is connected with the air cylinder; the whole power device is supported by a support. After the clamping jaws of the chuck are abraded, the power device is started to restore the clamping jaws of the chuck. The service life of the clamping jaws of the chuck is prolonged, and production cost is reduced.
Description
Technical field
The utility model relates to clamping tool for machine work technical field, particularly a kind of modified scroll chuck.
Background technology
Scroll chuck is a kind of application clamping device very widely, in process of production performer very important compared with look.Scroll chuck is made up of chuck body, movable jaw and claw driving mechanism.On scroll chuck below three claw targeting parts, there is screw thread to be meshed with the flat thread at the dish-shaped bevel gear back side, in the time rotating cone pinion with spanner by cubic hole, dish gear rotates, the flat thread at the back side drive simultaneously three claws to center near or exit, in order to clamp the workpiece of different-diameter.Be used on three claws and change three anti-pawls, be used for installing the workpiece that diameter is larger.The circumferential pressure producing at processing work can produce some microdefects at surface of the work, affects product quality and service life.Meanwhile, scroll chuck uses of a specified duration, and stepping up precision can decline, and chuck also there will be wearing and tearing in various degree.Utility model CN201310167622.9 once proposed a kind of turning attachment, the mechanical lock of scroll chuck was changed into the fluid-type locking of air pressure and oil pressure cooperation.Adopt the compressibility of air pressure, being bow and arrow carries out self-recision man-hour adding.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of modified scroll chuck.
Realize the technical solution of the utility model as follows: a kind of modified scroll chuck, comprise that the fluid-type locking that chuck, clamp and air pressure and oil pressure coordinate steps up pressing mechanism, separately add chuck jaws and repair power set and Boring cutter, power set include cylinder, expansion link, motor.At chuck hub axle, place arranges Boring cutter, at the chuck back side, power set is set; Boring cutter is connected with motor by connector; Motor is supported by bracing frame, and is connected with expansion link; The opposite side of expansion link is connected with cylinder; Whole power set are by stent support.
Described expansion link axially moves under the driving of cylinder.
Described motor, it drives Boring cutter to do High Rotation Speed grinding motion.
The beneficial effects of the utility model are: Boring cutter is set the service life of having improved chuck jaws.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the profile that the fluid-type locking of air pressure and oil pressure cooperation steps up the single clamp of pressing mechanism;
Fig. 3 is the structural representation after chuck is installed;
In accompanying drawing, 1 is chuck, and 2 is support, and 3 is Boring cutter, and 4 is connector, and 5 is motor, and 6 is bracing frame, and 7 is expansion link, and 8 is cylinder.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described;
Referring to shown in Fig. 1 to Fig. 3, a kind of modified scroll chuck is made some and is improved on the basis of citing document, adds chuck jaws and repairs power set and Boring cutter 3.In chuck 1 central axis, Boring cutter 3 is set, at chuck 1 back side, power set is set, power set include cylinder 8, expansion link 7, motor 5.Boring cutter 3 is connected with motor 5 by connector 4; Motor 5 is supported by bracing frame 6, and is connected with expansion link 7; The opposite side of expansion link 7 is connected with cylinder 8; Whole power set are supported by support 2.After claw wearing and tearing, the power set that start the chuck back side are repaired chuck jaws.After power set start, cylinder promotion expansion link 7 axially moves and Boring cutter is shifted onto to the position that needs reparation, and motor 5 drives Boring cutter 3 to do high-speed rotation the inner side fray of chuck jaws is rotated to grinding, thereby repairs chuck jaws.The utility model is improved the service life of chuck jaws.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model openly in scope; still can do some corrections or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
Claims (1)
