Abstract
The utility model discloses an automatic clamping hydraulic chuck, which comprises a chuck body, a cylinder and a draw bar. The automatic clamping hydraulic chuck is characterized in that one end surface of the chuck body is provided with a groove, a through hole is arranged at the bottom of the groove, a spring chuck is disposed in the groove, a clamping port of the spring chuck faces to the outer side of the groove, the inner end of the draw bar is inserted in the through hole and fixed onto the spring chuck, and the outer end of the draw bar is fixedly connected with a piston rod of the cylinder.
Description
Technical field:
The utility model relates generally to a kind of self-holding oild chuck.
Background technology:
Now some common and numerically controlled lathe scroll chuck clamping work pieces all are manual, and labor intensive has increased working time, and work efficiency is low when producing in a large number in batch, and dangerous.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, to provide a kind of energy simple in structure self-holding oild chuck.
The utility model is achieved through the following technical solutions:
A kind of self-holding oild chuck, include chuck body, oil cylinder, it is characterized in that: have the groove that inside dimension is shunk gradually on the end face of described chuck body one side, described bottom portion of groove has through hole, be equipped with collet in the described groove, the clamping mouthful of described collet towards the groove outside; Include pull bar, pull bar the inner is inserted in the through hole outside chuck body and is fixed on the collet, fixedlys connected with the piston rod of oil cylinder in the pull bar outer end.
Described pull bar is by being bolted on the collet, and during work, what workpiece clamp was contained in collet clamps the oral area position.
When the piston rod of oil cylinder pulling pull bar when moving to left, collet constantly moves in groove, because inside grooves shrinks gradually, so will be clamped gradually along with collet constantly moves it in groove, and then plays the purpose of clamping work pieces; When the piston rod pushing drawing rod of oil cylinder moves right,, collet constantly moves outside groove, will be loosened gradually along with collet constantly moves it outside groove, and then plays the purpose of unclamping workpiece.
The utility model has the advantages that:
The utility model is simple in structure, clamps conveniently, has improved work efficiency of workers.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
A kind of self-holding oild chuck, include chuck body 1, oil cylinder 6, have the groove that inside dimension is shunk gradually on the end face of described chuck body 1 one sides, described bottom portion of groove has through hole, be equipped with collet 2 in the described groove, the clamping mouthful of described collet 2 towards the groove outside; Include pull bar 3, pull bar 3 the inners are inserted in the through hole and by bolt 4 outside chuck body 1 and are fixed on the collet 2, fixedly connected with the piston rod 7 of oil cylinder 6 in pull bar 3 outer ends.During operation, workpiece 5 is installed in collet 2 clamps the oral area position.
