Self-positioning precision air-oil pressure clamp jig

Abstract

The invention relates to a self-positioning precision air-oil pressure clamp jig which is applied to a machining device. The jig comprises a fixed bed table and a locking device, wherein the fixed bed table is used for being connected with the machining device, the fixed bed table provides assembly for the locking device, a clamping module of the locking device is used for fixing a machined object and clamping the machined object, the machined object is machined by the machining device, a positioning module and a piston are arranged in the locking device, the piston can drive the positioning module and the clamping module, the positioning module provides assembly for the machined object, and meanwhile, the positioning module can be hidden in the locking device during machining without affecting machining, so that the purposes of improving the machining precision and the machining position accuracy can be achieved.

Description

technical field [0001] The present invention relates to a clamping tool used in a processing machine, in particular to an automatic positioning clamping tool. Background technique [0002] In the field of automatic processing operations, what troubles the operator is the convenience, stability and safety of the processed product. Although manual loading and unloading is very convenient, there will be uneven locking force when positioning the processed product manually. When the locking force is insufficient or too large, it will have an impact. For example, insufficient locking force sometimes causes the phenomenon that the workpiece is separated from the clamping fixture, or the problem of deformation of the processed object occurs when the locking force is too large. Therefore, At present, most of the fixtures have been developed towards the fixtures using stable media such as air pressure and oil pressure. [0003] In addition, some processed objects require high process...

[0002] In the field of automatic processing operations, what troubles the operator is the convenience, stability and safety of the processed product. Although manual loading and unloading is very convenient, there will be uneven locking force when positioning the processed product manually. When the locking force is insufficient or too large, it will have an impact. For example, insufficient locking force sometimes causes the phenomenon that the workpiece is separated from the clamping fixture, or the problem of deformation of the processed object occurs when the locking force is too large. Therefore, At present, most of the fixtures have been developed towards the fixtures using stable media such as air pressure and oil pressure.

[0003] In addition, some processed objects require high processing precision in addition to the accurate processing position; the current common practice is to set at least one movable positioning unit on the jig so that the processed object can be assembled on the jig for processing, but the movable Before cutting the positioning unit, the positioning unit must be removed. If the positioning unit is not removed, it may cause processing interference or mechanical confusion.

[0004] Moreover, it takes a considerable amount of time to correct the positions of the jig and the positioning unit through the above-mentioned structure, which greatly increases the manufacturing cost of the processor
