M-type drilling tool for pipes with multiple rows of holes

Abstract

The invention discloses an M-type drilling tooling for multi-row hole pipe fittings. The workpiece radial positioning device is fixedly installed on the base, and includes a workpiece support surface and a workpiece pressing mechanism. The workpiece support surface has an M-shaped structure in section; the workpiece shaft The orientation positioning device includes an end face positioning mechanism and a center angle positioning mechanism; the end face positioning mechanism is set at one end of the workpiece supporting surface; the circle center angle positioning mechanism is set at the other end of the workpiece supporting surface, including indexing plates, front and rear telescopic parts and positioning locking parts The front and rear telescopic parts are set in the cavity formed between the M-shaped structure of the workpiece support surface and the base, and the front and rear telescopic parts are slidingly connected with the workpiece support surface; the indexing plate is fixedly installed at one end of the front and rear telescopic parts; the positioning locking mechanism corresponds to The front and rear telescopic parts are arranged on the base or the workpiece radial positioning device. The M-type drilling processing tool for the multi-row hole pipe fitting can realize rapid positioning drilling processing and improve drilling work efficiency under the premise of ensuring the drilling processing quality.

Description

technical field [0001] The invention relates to a drilling tool, in particular to an M-shaped drilling tool for drilling a pipe fitting with multiple rows of holes, and belongs to the technical field of mechanical processing. Background technique [0002] The full name of tooling is process equipment, which is a device used to fix the parts to be processed for accurate processing. It is not only the production equipment and tools in the production enterprise, but also the equipment to cooperate with the production equipment and personnel to complete the process production requirements. Most of the tooling is specially made according to the characteristics of their respective products. [0003] Pipe fittings with multiple rows of holes in the axial or radial direction, such as water pipes with multiple drip nozzles for drip irrigation and water pipes with multiple nozzles for wet dust removal, are usually passed directly on the vertical drill such as angle irons.

Problems solved by technology

[0003] Pipe fittings with multiple rows of holes in the axial or radial direction, such as water pipes with multiple drip nozzles for drip irrigation and water pipes with multiple nozzles for wet dust removal, are usually passed directly on the vertical drill such as angle irons. The drilling tooling with V-shaped positioning surface is used for drilling and processing. The existing multi-hole pipe fitting drilling processing tool usually has an end face positioning mechanism. After being fixed on the V-shaped positioning surface of the drilling tool, it is drilled according to the drilling line. Although this traditional drilling tool can improve productivity and is suitable for mass production, it still has the following defects: multi-row hole pipe fittings need Drilling and scribing in advance, the scribing process is not only time-consuming, resulting in low processing efficiency, but also there are human errors in the scribing, and the processing quality is not easy to guarantee; for pipe fittings with multiple rows of holes in the radial direction, the workpiece needs to be rotated circumferentially, drilled The hole is more troublesome, and the quality of drilling depends entirely on the marking of the drilling, and the processing quality is even more difficult to guarantee
