A kind of opposite linkage self-adaptive fixture

Abstract

The invention discloses an opposite-linkage self-adapting fixture. The opposite-linkage self-adapting fixture comprises a bottom plate, and a screw rod, a guide rail, a first clamping block, a second clamping block, a first locating block, a second locating block and a driving system for driving the screw rod to rotate are arranged on the bottom plate; the bottom of the first clamping block, the bottom of the second clamping block, the bottom of the first locating block and the bottom of the second locating block are all provided with first grooves matched with the guide rail, and the first clamping block, the first locating block, the second locating block and the second clamping block are sequentially distributed from left to right; threaded holes matched with the screw rod are formed in the first clamping block and the second clamping block, and the screw rod penetrates the threaded hole in the first clamping block and threaded holes in the first locating block, the second locating block and the second clamping block sequentially; and the top of the first locating block and the top of the second locating block are each provided with a second groove which is used for locating a part to be clamped. The opposite-linkage self-adapting fixture can accurately clamp the part to be clamped.

Description

technical field [0001] The invention belongs to the field of fixture design, and designs a fixture, in particular to a counter-linkage self-adaptive fixture. Background technique [0002] People have a long history of research on the design of fixture systems. The former Soviet Union began the research on fixture CAD as early as the early 1970s. Due to the backward development of computer software and hardware, it was greatly restricted. In the 1980s, many scholars and companies in the United States and Europe devoted themselves to this work, and after the mid-1980s, a small number of scholars in mainland China and Taiwan also began to conduct research. A.Markus designed an expert system for machine tool fixtures in prolog language in 1984, which belongs to the earlier fixture automatic design system. The system cannot determine the positioning and clamping points, but focuses on the assembly of the combined fixture. When the shape of the workpiece, design parameters and po...
