Embodiment Construction

[0015] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing, see Figure 1-7 As shown, the wire electric discharge cutting fixture includes a base 10 and a pressing plate 9 arranged on the base. The pressing plate 9 is locked on the base 10 through the pressing bolt 1. The pressing bolt 1 is used to compress the workpiece to be processed. The base The upper side of the front end surface of 10 and the lower side of the front end surface of the pressing plate 9 are respectively provided with corresponding elongated strips, and one end has a curved groove structure. The base 10 of the wire cutting fixture and the pressing plate 9 are closely connected together to form a The workpiece clamping groove 11 for clamping the workpiece; the upper side of the front end of the pressing plate 9 in the height direction also has a fine-tuning seam 8 whose gap width can be fine-tuned. Fine-tuning block placement groove 12 co...

Abstract

The invention provides a fixture for wire-cut electrical discharge machining of workpieces with the different lengths and different shapes and particularly relates to the field of fixtures. The fixture comprises a base and a pressing plate arranged on the upper portion of the base; a sliding groove matched with a T-shaped block on the base is formed in the pressing plate and can be used for adjusting the height of a workpiece clamping groove; four positioning screws on the pressing plate are used for guaranteeing positioning of the workpiece, and two compressing bolts on the pressing plate areused for compressing the workpiece so as to facilitate mounting and demounting of the to-be-machined workpiece; two eye bolts are additionally arranged on the pressing plate; and in addition, aimingat the detect that numerous fixtures fail in precise fine adjustment of the levelness, according to the fixture, fine adjustment block storing grooves are excavated in the upper side of the front endface of the pressing plate, and the workpiece clamping precision can be guaranteed through bolts on fine adjustment blocks. The fixture has the beneficial effects that the fixture can mount, positionand clamp the workpiece on a wire-cut machine tool flexibly and rapidly even if the workpiece is long or is in an irregular shape, and the working efficiency is improved greatly.

Description

technical field [0001] The invention relates to the field of electric sparks, in particular to a clamp for a wire cutting machine tool.
