Abstract
The utility model provides a manual connecting rod chuck, which comprises a shell and a hand wheel arranged on the shell, wherein one end of the shell is movably connected with a turntable, the turntable is movably connected with a plurality of connecting rods with evenly distributed circumferences, and one end of the shell is provided with a first guide groove for guiding the connecting rods; the end part of the connecting rod is connected with a clamping jaw positioned at the other end of the shell, and the other end of the shell is provided with a second guide groove which corresponds to the first guide groove and guides the clamping jaw; the hand wheel drives the turntable through a power transmission structure. The rotary table is driven to rotate through the hand wheel, the rotary table rotates to drive the connecting rod to slide in the first guide groove, so that the clamping jaws are driven to slide in the second guide groove, and the clamping or loosening of the workpiece by the clamping jaws is realized; compared with a pneumatic device or an electric device, the hand wheel is low in price, and the cost of the chuck is reduced.
Description
Technical Field
The utility model relates to a chuck technical field specifically is a manual connecting rod chuck.
Background
The chuck is a mechanical device used for clamping a workpiece on a machine tool, and is a machine tool accessory for clamping and positioning the workpiece by utilizing the radial movement of movable clamping jaws uniformly distributed on a chuck body; the chuck generally comprises a chuck body, a movable jaw and a jaw driving mechanism. The driving mechanism is generally pneumatic or electric, but for some fields with low precision requirements, the pneumatic or electric claw is higher in cost.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the technical problem that the traditional pneumatic or electric chuck is high in cost is solved.
The utility model provides a manual connecting rod chuck, which comprises a shell and a hand wheel arranged on the shell, wherein one end of the shell is movably connected with a turntable, the turntable is movably connected with a plurality of connecting rods with evenly distributed circumferences, and one end of the shell is provided with a first guide groove for guiding the connecting rods;
the end part of the connecting rod is connected with a clamping jaw positioned at the other end of the shell, and the other end of the shell is provided with a second guide groove which corresponds to the first guide groove and guides the clamping jaw;
the hand wheel drives the turntable through a power transmission structure.
The rotary table is driven to rotate through the hand wheel, the rotary table rotates to drive the connecting rod to slide in the first guide groove, so that the clamping jaws are driven to slide in the second guide groove, and the clamping or loosening of the workpiece by the clamping jaws is realized; compared with a pneumatic device or an electric device, the hand wheel is low in price, and the cost of the chuck is reduced.
Furthermore, the power transmission structure comprises a worm wheel and a worm which are meshed with each other, the worm wheel is fixedly connected with the turntable, and one end of the worm is fixedly connected with the hand wheel. The worm wheel and the worm have a self-locking function when meshed, and the clamping jaw cannot automatically loosen when clamping a workpiece.

Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1 and 2, the utility model relates to a manual connecting rod chuck, which comprises a shell 1 and a hand wheel 3 arranged on the shell 1, wherein one end of the shell 1 is movably connected with a turntable 2, the turntable 2 is movably connected with four connecting rods 4 with evenly distributed circumference, and one end of the shell 1 is provided with a first guide groove 11 for guiding the connecting rods 4;
the end of the connecting rod 4 is connected with a jaw 6 positioned at the other end of the shell 1, and as shown in fig. 3, the other end of the shell 1 is provided with a second guide groove 12 which corresponds to the first guide groove 11 and guides the jaw 6;
the rotary table 2 is fixedly connected with a worm wheel 51, the worm wheel 51 is meshed with a worm 52, and one end of the worm 52 is fixedly connected with the hand wheel 3;
the hand wheel 3 is meshed with a worm gear 51 through a worm 52 to serve as a power transmission structure 5 to drive the rotary table 2 to rotate, the rotary table 2 rotates to drive the connecting rod 4 to slide in the first guide groove 11, so that the clamping jaw 6 is driven to slide in the second guide groove 12, and the clamping jaw 6 clamps or loosens a workpiece; compared with a pneumatic device or an electric device, the hand wheel 3 is low in price, the cost of the chuck is reduced, the worm wheel 51 and the worm 52 have a self-locking function when being meshed, and the phenomenon that the clamping jaw 6 cannot automatically loosen when clamping a workpiece is avoided.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
