An elastic clamping positioning device

Abstract

The invention provides an elastic clamping and positioning device and belongs to the technical field of manufacture of aero-engine components and parts. A plurality of clamping and positioning portions are arranged on a base of the elastic clamping and positioning device and distributed evenly. Elastic clamping blocks of the clamping and positioning portions are fixedly installed on the base, and elastic chucks are arranged at the top end of the elastic clamping blocks. Forward and reverse threads are respectively arranged at two ends of each lead screw, the middles of the lead screw are located in through holes of the elastic clamping blocks, and the forward and reverse thread ends of the lead screws are respectively sleeved by the first rigid clamping blocks and the second rigid clamping blocks are respectively through forward and reverse thread holes in the clamping blocks. The clamping directions of the elastic chucks are perpendicular to the clamping directions of the first rigid clamping blocks and the second rigid clamping blocks. The first rigid clamping blocks and the second rigid clamping blocks are symmetrically arranged along a horizontal clamping central line. Guiding blocks are respectively arranged on two sides of each rigid clamping block, and the rigid clamping blocks are matched with the guiding blocks in a sliding contact mode.

Description

technical field [0001] The invention belongs to the technical field of manufacturing aero-engine components, in particular to an elastic clamping and positioning device. Background technique [0002] In the manufacturing process of aero-engine parts, the workpieces that need to be clamped and positioned before processing account for the vast majority. However, due to the different fixtures used for the same workpiece, even if the same processing equipment and processing method are used, the final processing of the workpiece The quality will also vary, as will the processing efficiency. For the processing of small and medium-sized workpieces, it is not only required to ensure the processing quality, but also to ensure the processing efficiency and processing cost. However, the fixtures used in the traditional processing of small and medium-sized workpieces are special tooling fixtures, which can only be used alone. Only a single workpiece can be clamped inside, and the clamp...

Problems solved by technology

For the processing of small and medium-sized workpieces, it is not only required to ensure the processing quality, but also to ensure the processing efficiency and processing cost. However, the fixtures used in the traditional processing of small and medium-sized workpieces are special tooling fixtures, which can only be used alone. Only a single workpiece can be clamped inside, and the clamped workpiece can only be processed separately, which leads to low processing efficiency, high processing cost, and difficult control of processing quality

Because the volume of small and medium-sized workpieces is generally relatively small, and the processing time of a single workpiece is not long, this leads to frequent clamping and dismantling of the workpiece by the operator, and the labor intensity of the operator is very high.
