High-efficiency hydraulic clamp

Abstract

The invention discloses a high-efficiency hydraulic clamp. The high-efficiency hydraulic clamp comprises a clamp base and two clamp units which are arranged on the clamp base. Each clamp unit comprises a collet chuck and a piston sleeve, wherein the collet chuck is arranged in the clamp base in a penetrating mode, and the piston sleeve is arranged between the clamp base and the collet chuck in a sleeving mode; the front end of the piston sleeve stretches out of the clamp base; a plurality of contracting notches are formed in the front end of the collet chuck in the axial direction, and receding notches corresponding to the contracting notches are formed in the front end of the piston sleeve in the axial direction; and a first conical face is arranged on the outer wall of the front end of the collet chuck, and a second conical face attached to the first conical face is arranged on the inner wall of the front end of the piston sleeve. A first oil port and a second oil port which are matched with the piston sleeves correspondingly are formed in the clamp base. The high-efficiency hydraulic clamp is simple and reasonable in structure arrangement, convenient to use and high in stability; and two workpieces can be clamped at the same time, multiple procedures for machining the workpieces can be completed through one-time clamping of each clamp unit, the workload can be reduced easily, and the machining efficiency and machining precision are improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a high-efficiency hydraulic clamp. Background technique [0002] As we all know, a workpiece usually has multiple processing procedures according to the requirements of the processing technology. For example, in the production process of the gas valve, its spool 1' (see figure 1 ) requires multiple processes, including: (1), milling the radial groove 11' on the end face; (2), milling the first axial groove 12'; (3), milling the second axial groove 13'; (4), radially drilling 14' in the middle of the workpiece; (5), deburring the shaft hole 15' of the workpiece. During the processing, since the processing positions and processing angles of each process are different, if the existing fixtures are used, at least multiple clampings are required to complete the processing of the valve core 1'. Such multiple clamping and positioning not only increases the workload and ...

Problems solved by technology

Such multiple clamping and positioning not only increases the workload and reduces the processing efficiency, but also affects the machining accuracy because each clamping and positioning cannot be guaranteed to be exactly the same.
