Irregular blank workpiece clamping table for vertical milling machine

Abstract

The invention discloses an irregular blank workpiece clamping table for a vertical milling machine, and belongs to the field of machining. The irregular blank workpiece clamping table comprises a workpiece groove, fixing rods are arranged on the side walls of the workpiece groove, and fasteners are arranged at the ends, placed in the workpiece groove, of the fixing rods. Each fastener comprises a casing structure, and a clamping piece is arranged at one end of each casing structure. The clamping pieces and the casing structures are hinged to each other, and bore spines are arranged on the clamping pieces. A telescopic supporting rod is arranged at the bottom in the workpiece groove, and a pressure-bearing mechanism is arranged at one end of the telescopic supporting rod. A clamping layer is arranged on the upper portion of the workpiece groove, and a pair of opposite edges of the clamping layer are each provided with a movable vice jaw. Compared with the prior art, through the horizontal clamping of multiple supporting points and the multi-point fixing to workpieces of the clamping layer, blank pieces in various shapes can be clamped; the phenomenon that the blank pieces need to be subjected to rough machining first to be in regular shape so as to be clamped conveniently is needless, and large cutting allowance is reserved for subsequent machining; and moreover the labor intensity is lowered, and manpower and material resources are saved.

Description

technical field [0001] The invention relates to a clamping tool for mechanical processing, in particular to a clamping table for irregular blank workpieces for vertical milling machines. Background technique [0002] The rough parts of general machining are usually manufactured by steel foundries. The surface is rough and the various parts of the surface are uneven. This kind of rough machining usually has a large amount of cutting, leaving only a little allowance for finishing, which virtually increases the workload and prolongs the working time. However, when encountering some single-sided machining parts, follow the previous processing steps , it is necessary to cut the outer circle into a regular shape on the other side, which is convenient for clamping and wastes manpower and material resources, or for some special-shaped workpieces, it is not easy to clamp, and the clamping force is not enough to cause accidents, which will bring harm to the operator. security threa...

Problems solved by technology

The fixture uses variable clamping components for clamping. Although it meets the clamping requirements of workpieces of various shapes and sizes, its clamping force is small and the degree of grip on the workpiece is low. It can only be used for some small and light. The workpiece is clamped, and it cannot be used for large-volume and heavy-weight workpieces
