Description
Technical field
The present invention relates to a kind of fixture, and in particular to a kind of chuck.
Background technology
The existing chuck for being used to process brake disc, including support base, cylinder, clamping device, clamping device include connection
Part, connecting rod, fixture block, cylinder rod drive fixture block to move by connector, connecting rod, due to cylinder moving direction and fixture block motion
Direction is vertical, connecting rod close to it is vertical when, horizontal direction component very little, clamping effect is poor.
The content of the invention
The purpose of the present invention is that there is provided a kind of chuck for existing deficiency.
The purpose of the present invention is realized by following technological means：
Including support base, workseat, telescoping cylinder, clamping device, telescoping cylinder is arranged on below support base, and workseat is arranged on folder
Hold above mechanism, clamping device includes connector, three gripping mechanisms, gripping mechanism is circumferentially uniformly arranged on above support base,
Connector lower end connects telescoping cylinder, and three gripping mechanisms are hinged above, and gripping mechanism includes connecting rod, the first rack, the second tooth
Bar, gear and fixture block, connecting rod one end articulated joints, the other end are hinged the first rack, and the first rack, the second rack are relative to be set
Put in gear both sides and engaged with gear, the second rack connection fixture block.
It is preferred that scheme, the first rack back side is provided with guide pad, and there is extension on guide pad top, and extension extends to first
The top of rack；The second rack back side is provided with guide pad, and there is extension on guide pad top, and extension extends to the upper of the second rack
Side..
The present invention has following clear advantage compared with prior art：When telescoping cylinder extends, pass through connector, connecting rod
Drive the first rack to move out, the second rack is inwardly moved using gear, fixture block is inwardly moved therewith, realize clamping work(
Can, connecting rod is close to horizontal movement, and horizontal direction component is big, good clamping effect.
Brief description of the drawings
Fig. 1 is three-dimensional structure diagram of the invention；Fig. 2 is the top view that Fig. 2 is gripping mechanism.
Embodiment
Below in conjunction with brief description of the drawings, the present invention is described in further detail with embodiment：In figure, 1 support
Seat, 2 cylinders, 3 workseats, 4 connectors, 5 connecting rods, 6 first racks, 7 guide pads, 8 fixture blocks, 9 second racks, 10 gears.
Chuck as depicted, including support base 1, workseat 3, cylinder 2, clamping device, cylinder 2 are arranged on support base 1
Below, workseat 3 is arranged on above clamping device, and clamping device includes connector 4, three gripping mechanisms, gripping mechanism week
To being uniformly arranged on above support base 1, connection cylinder rod in the lower end of connector 4 is hinged three gripping mechanisms, gripping mechanism bag above
Include connecting rod 5, the first rack 6, the second rack 9, gear 10 and fixture block 8, one end articulated joints 4 of connecting rod 5, the other end is hinged
First rack 6, the first rack 6, the second rack 9 are oppositely arranged on the both sides of gear 10 and engaged with gear 10, and the second rack 9 is connected
Fixture block 8.
First rack 6, the back side of the second rack 9 are provided with guide pad 7, and there is an extension on the top of guide pad 7, and extension extends to the
The top of one rack 6, the second rack 9, prevents from changing the direction of motion during two rack stress.
