A Digital Radial Drilling Machine

Abstract

The invention provides a numerical display type radial drilling machine, comprising a spindle speed regulating and spindle feeding speed regulating system, a spindle feeding mechanism, a spindle and balance mechanism, a spindle positive / negative rotation and variable-speed control mechanism, a rocker arm and clamping mechanism, an upright and rocker arm lifting mechanism, a hydraulic and cooling system, a testing system, a numerical display control system and the like; the upright and rocker arm lifting mechanism is mounted on a base; the rocker arm and clamping mechanism is mounted on the upright and rocker arm lifting mechanism; the numerical display control system is mounted on the upright and rocker arm lifting mechanism; the spindle speed regulating and spindle feeding speed regulating system is mounted on the rocker arm and clamping mechanism; the spindle feeding mechanism, the spindle and balance mechanism, the spindle positive / negative rotation and variable-speed control mechanism, and the hydraulic and cooling system are mounted on the spindle speed regulating and spindle feeding speed regulating system. According to the numerical display type radial drilling machine, stepless speed changing of a spindle can be realized without shutdown; graphic and numerical display can be realized at working positions; a die wall clamping device of a guide rail and a spindle limiting structure are sensitive and reliable; in short, the numerical display type radial drilling machine is applicable to machining industries.

Description

technical field [0001] The invention relates to a digital display radial drilling machine in the mechanical processing industry. Background technique [0002] At present, in the mechanical processing industry, the radial drilling machine is a kind of machine tool used for single-piece or batch production of hole processing for large parts with holes. Generally, the spindle box can move on the rocker arm and rotate around the column with the rocker arm. The rocker arm moves up and down along the column to adapt to processing workpieces of different heights. Smaller workpieces are mounted on the table, and larger workpieces are placed directly on the machine base or the ground. Radial drilling machines are widely used in single-piece and small and medium-sized batch production to process holes in workpieces with large volume and weight. The main variants of radial drilling machines are slide type and universal type. The slide type radial drilling machine is made by changin...

AI Technical Summary

Problems solved by technology

[0006] Although the radial drilling machine has a history of more than 100 years, there are still many shortcomings. The spindle cannot change speed without stopping, and it cannot realize infinitely variable speed. The working position cannot be displayed in graphics and numbers, and the guide rail structure is still worn. Difficult post-repair, poor guiding accuracy of the guide rail, unlimited spindle function, relatively backward control system, some operations are difficult to realize, cooling water is easy to spray into the digital display control system, complex structure, high cost, poor function, low strength and rigidity, transmission Low precision, short service life, time-consuming and laborious, many parts, high failure rate
