Summary of the invention
Technical problem to be solved by this invention is: provide a kind of scroll chuck that firmly can clamp workpiece.
Technical scheme of the present invention is: a kind of scroll chuck, it comprise chuck body, driver card disk body rotate device, claw driving mechanism and driven the multiple claws clamping or open by claw driving mechanism; Described chuck body and to drive with clamping or multiple claws of opening by claw driving mechanism be two covers, and two cover chuck body coaxial lines are installed, described claw driving mechanism is a set of, and overlaps claw connect synchronously drive with two; Two described cover chuck bodies are arranged in frame through bearing, and are connected with the device that driver card disk body rotates.
After adopting above structure, tool of the present invention has the following advantages: because chuck body has two covers, workpiece is placed on chuck body, claw can be made to clamp two diverse locations on axis of workpiece, clamping work pieces that can be more stable by claw driving mechanism.
As improvement, described claw driving mechanism comprises the power cylinder be vertically arranged on bracing frame, the free end of power cylinder piston rod is connected with vertical bar shaped gear, described chuck body is coaxially set and the gear of bar shaped gears meshing; Described gear is arranged on the radial annulus on chuck body in the middle part of cylindrical drum; Described cylindrical drum two ends are fixed with the contrary helicla flute of direction of rotation; Described helicla flute engages with the latch on respective a set of claw.
As improvement, the radial convex loop in described cylindrical drum is provided with circular arc through hole; Two described cover chuck body edges are provided with multiple through hole of locating for alignment pin with circular arc through hole coaxial line, can well realize positioning chuck body by alignment pin.
As improvement, the device that described driver card disk body rotates comprises rack-mounted motor, be arranged on synchronous pulley on motor reel and overlap with described two the synchronous pulley that chuck body coaxial line is fixedly connected with; Two described synchronous pulleys are connected by Timing Belt, can well be rotated by driver card disk body by belt pulley.

Detailed description of the invention
Below in conjunction with accompanying drawing, enforcement of the present invention is further described.
A kind of scroll chuck, it comprises chuck body 1, driver card disk body rotates device, claw driving mechanism and driven the multiple claws 2 clamping or open by claw driving mechanism; It is characterized in that: described chuck body 1 and to drive with clamping or multiple claws 2 of opening by claw driving mechanism be two covers, and two cover chuck body 1 coaxial lines are installed, described claw driving mechanism is a set of, and overlaps claw 2 connect synchronously to drive with two; Two described cover chuck bodies 1 are arranged in frame 4 through bearing 3, and are connected with the device that driver card disk body rotates.
Described claw driving mechanism comprises the power cylinder 5 be vertically arranged on bracing frame 13, the free end of power cylinder 5 piston rod is connected with vertical bar shaped gear 6, described chuck body 1 has been coaxially set and bar shaped gear 6 meshed gears 7; Described gear 7 is arranged on the radial annulus on chuck body 1 in the middle part of cylindrical drum 8; Described cylindrical drum 8 two ends are fixed with the contrary helicla flute of direction of rotation 8.1; Described helicla flute 8.1 engages with the latch on respective a set of claw 2.
Radial convex loop in described cylindrical drum 8 is provided with circular arc through hole 8.2; Two described cover chuck body 1 edges are provided with multiple through hole 12 of locating for alignment pin 11 with circular arc through hole 8.2 coaxial line.
The device that described driver card disk body rotates comprises rack-mounted motor 9, be arranged on synchronous pulley on motor reel and overlap with described two the synchronous pulley that chuck body 1 coaxial line is fixedly connected with; Two described synchronous pulleys are connected by Timing Belt 10; Described motor 9 is servomotor, because servomotor has auto-lock function can realize the clamping of workpiece well or unclamp.
The present invention in specific implementation process is: workpiece is placed on chuck body, bar shaped gear and gears meshing, start power cylinder, the Sports band moving gear of bar shaped gear rotates, drive spiral fluted to rotate again, due to the latch on claw and helicla flute engagement, claw can along the claw orbital motion on chuck body, thus Automatic-clamping can be realized or unclamp workpiece, time saving and energy saving; For being slidably matched between power cylinder and bracing frame, when claw clamping or when unclamping workpiece, sliding power cylinder left, makes bar shaped gear and gear disengage, can convenient card disk body work.And have two covers due to chuck body, and two diverse locations of workpiece can be clamped, can more firmly clamping work pieces.
