Description
Technical field
The utility model belongs to field of machining, is specifically related to a kind of work holder.
Background technology
What on production line volume is adopted usually than the clamping of big article at present is the parallel clamping device of linear slide rail, this kind apparatus structure complexity then, and cost is higher, the topmost very flexible that is to use.
The utility model content
For overcoming deficiency of the prior art, it is a kind of simple in structure, compact that the purpose of this utility model is to provide, and uses flexibly, and cost is low, and the life-span is long, safeguards to be easy to work holder.
In order to solve the problems of the technologies described above, realize above-mentioned purpose, the utility model has adopted following technical scheme:
A kind of work holder, comprise a crossbeam, one drive rod frame is installed on the described crossbeam, the two ends of described crossbeam are separately installed with one and connect arm seat, in described each connection arm seat first linking arm and second linking arm are installed, described first linking arm and second linking arm are installed in the pawl holder together, on the described pawl holder gripper jaw are installed; On the described drive rod frame drive rod is installed, is connected with two connecting rods on the described drive rod, described each connecting rod connects a linking arm; Described linking arm is connected on described first linking arm.
Further, described gripper jaw becomes chela formula structure.
Further, holding angle is a zero degree under the described gripper jaw clamp position, has certain open-angle under the open configuration.
Further, described open-angle is determined by first linking arm between described pawl holder and the connection arm seat and the relative installation of second linking arm.
Further, the type of drive of described drive rod can be rotation and drives or linear drives, power source can be electronic, hydraulic pressure or pneumatic.
Further, the two ends of crossbeam can be provided with axle head, and use bearing fixing, and then this work holder can be done the workpiece rotation after with piece-holder and carries.
The utlity model has following advantage:
1, simple in structure, compact.
2, flexible and convenient to use.
3, widely applicable.
4, the life-span is long.
5, low cost of manufacture.
6, safeguard easily.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
