Abstract

A flexible fixture for batch machining of shaft workpieces comprises a fixture bottom plate, a rotation system, centering, positioning and clamping mechanisms, an auxiliary support mechanism and floating positioning devices; during using, five degrees of freedom of multiple machined workpieces can be limited simultaneously after matching of the centering, positioning and clamping mechanisms and the floating positioning devices, and the auxiliary support mechanism is used for performing auxiliary support on to-be-machined areas of the workpieces. The fixture is adopted for batch mounting of 10 long and thin shaft workpieces with the diameter of phi 10 mm-phi 30 mm and the length of 100-800 mm and realizes technological processes of milling, drilling, expanding, reaming, boring and the like on equipment of a vertical machining center. The flexible fixture has the advantages as follows: 1, increase and decrease of the number of the mounted workpieces, range extension of the diameter of the workpieces and range extension of the length of the workpieces can be realized through replacement of part of mechanical workpieces; 2, 2 servo motors are additionally arranged on the fixture on the vertical machining center with relatively lower cost, and batch machining of the long and thin shaft workpieces is realized.

Description

technical field [0001] The invention relates to the field of fixture design for slender shaft workpieces. Background technique [0002] Slender shaft workpieces are commonly used workpieces. After the outer circle is processed, there are planes, curved surfaces, straight holes, tapered holes, pin holes, etc. that need to be processed. There are two main process solutions: 1. The principle of dispersed processes is more adopted. Each process is designed with a special fixture and processed on general-purpose equipment. The overall cost is high and the efficiency is low. 2. Adopting the principle of process concentration and processing on the turning-milling compound machining center, the input cost is high, the quality is not guaranteed, and the overall efficiency is low. Contents of the invention [0003] The invention provides a flexible fixture for batch processing shaft workpieces, which comprehensively improves the processing efficiency and reduces the processing cost...
