Horizontal four-head drilling and tapping machine

Abstract

The invention discloses a horizontal four-head drilling and tapping machine which comprises a machine tool. The machine tool is provided with a template fixing mechanism and cutter devices. The template fixing mechanism comprises a base arranged on the machine tool in a sliding mode, a fixed plate is arranged above the base, a movable plate is arranged on the other side of the base, and a template groove used for fixing a template is formed between the fixed plate and the movable plate. One side of the base is used for being connected with an oil hydraulic cylinder of the movable plate. The number of the cutter devices is two. Each cutter device comprises a cutter base and a lifting table, wherein the lifting table is a worm and gear lifting machine, the upper end of the lifting table is connected with the cutter base, a plurality of linear sliding table mechanisms are arranged on the cutter base, a drilling main shaft and a tapping main shaft are rotationally arranged on the linear sliding table mechanisms located on the two sides, and a centering rod is arranged on the linear sliding table mechanism located in the middle. Compared with the prior art, the whole device has the advantages of being compact in structure, high in automation degree, accurate in machining, high in working efficiency and suitable for application and popularization.

Description

technical field [0001] The invention relates to the field of drilling and tapping machines, in particular to a horizontal four-head drilling and tapping machine. Background technique [0002] Nowadays, with the rapid development of industry, drilling and tapping have become common production processes and production steps in industry, and with the progress of society, the requirements for processing equipment are getting higher and higher. [0003] Generally, drilling and tapping are required for the processing of the ring holes of the formwork. The formwork is composed of multiple templates, and each template needs to be placed on the machine tool for processing. Due to the weight of the template, it is generally necessary to place it on the machine tool by a crane. However, the existing drilling and tapping machines are all vertical radial drilling machines, which require manual operation. There are multiple lifting rings on each template. When machining with a type radia...

[0003] Generally, drilling and tapping are required for the processing of the ring holes of the formwork. The formwork is composed of multiple templates, and each template needs to be placed on the machine tool for processing. Due to the weight of the template, it is generally necessary to place it on the machine tool by a crane. However, the existing drilling and tapping machines are all vertical radial drilling machines, which require manual operation. There are multiple lifting rings on each template. When processing with radial arm drilling machine, iron chips are easy to splash and get stuck on the drill shaft or tapping shaft or in the gap of the machine tool, which is inconvenient to clean
