Indexing type drilling and chambering device

Abstract

The invention provides an indexing type drilling and chambering device which is composed of a working part, a positioning clamping part, an alignment and positioning indexing part and a clamp body. The working part is installed at the top end of the clamp body and is used for guiding a drill bit when a hole and a hole system are machined, the positioning clamping part is installed on a core shaftto be used for positioning and clamping workpieces, and the workpieces are positioned through the core shaft to serve as a first positioning standard to eliminate movement and rotation freedom in theY and Z directions. By means of the indexing type drilling and chambering device, drilling and chambering of the radial multi-station hole system of a rotation body type part with indexing requirements can be effectively achieved, the indexing machining accuracy is high, the structure is simple, manufacturing is convenient, the cost is low, maintenance is convenient, and components can be replacedconveniently under the condition that one drilling sleeve is damaged; and the production efficiency is high, the economical efficiency is high, two processes including drilling and chambering can becompleted through one-time clamping, the indexing type drilling and chambering device is particularly suitable for medium and small batch production, and a certain universality and continuity are achieved.

Description

technical field [0001] The invention relates to an indexing type drilling and reaming device. Background technique [0002] With the rapid development of manufacturing technology, various high-tech equipment and processing methods are increasingly used in mechanical processing, but the simplest, most economical and convenient processing method is still the first choice for mechanical processing. [0003] For the drilling and reaming of the radial multi-station hole system with indexing requirements for rotary parts, at present, the fitter scribing process, the indexing head for indexing processing and processing on the machining center are mainly used. After the drilling is completed Then transfer to the fitter for hole reaming. [0004] However, the method of scribing processing has poor precision, high labor intensity and low production efficiency; the use of dividing heads for processing, firstly, the number of dividing heads is limited, and the processing speed is also ...

Problems solved by technology

[0004] However, the method of scribing processing has poor precision, high labor intensity and low production efficiency; the use of dividing heads for processing, firstly, the number of dividing heads is limited, and the processing speed is also slow, and thirdly, clamping and positioning tools are required ;Machining with a machining center, although the precision is high, but the requirements for the machine tool are relatively high, a four-axis or five-axis machine tool is required, and the clamping and positioning tooling is still required, and the processing cost is high
