Radial drilling machine

Abstract

A radial drilling machine comprises a cross arm lifting mechanism, a cross arm clamping mechanism and an upright column clamping mechanism. The cross arm lifting mechanism comprises a three-phase alternating-current motor, a coupler, a worm gear elevator and a lifting lead screw. The three-phase alternating-current motor is connected with the worm gear elevator through the coupler, and the worm gear elevator is connected with the lifting lead screw through a key and is locked through two round nuts and check washers for the round nuts. The cross arm clamping mechanism comprises a torque motor, a passing speed reducer, an upper microswitch, a push block, a lower microswitch, a clamping and pressing rod, a flat key and a motor shaft. The upright clamping mechanism comprises a speed reducer, a torque motor, a pin roller, a gear, a clamping belt, a gear box, a stop block and a pin roller guide plate. The radial drilling machine has the advantages that electric clamping time is short, and responses are quick; mechanical mechanisms are matched with electric appliance elements, responses are quick, and sensitivity is high; the fault rate of products caused by hydraulic problems is lowered; the production period is shortened and the production rate is increased; controllability of product quality is improved.

Description

Technical field [0001] The invention relates to the field of machine tools, in particular to a radial drilling machine. Background technique [0002] Radial drilling machines are commonly used equipment for hole processing. The existing radial drilling machines are divided into mechanical radial drilling machines and hydraulic radial drilling machines. Mechanical radial drilling machine, all parts of the clamping are clamped manually, which prolongs the processing time and increases the labor intensity of the workers. Now it is relatively less used. Hydraulic rocker drilling machine is the main structural form of rocker drilling machine at present. The hydraulic cylinder is driven by an oil pump to achieve clamping, including headstock clamping, cross arm clamping, and column clamping. This clamping method is convenient and reliable, but hydraulic clamps Tight response time is long, hydraulic components have high environmental requirements, short service life, frequent replaceme...

Problems solved by technology

The hydraulic radial drilling machine is currently the main structural form of the radial drilling machine. The hydraulic cylinder is driven by the oil pump to achieve clamping, including spindle box clamping, cross arm clamping, and column clamping. This clamping method is convenient and reliable, but hydraulic clamping The tight response time is long, the hydraulic components have high requirements on the environment, the service life is short, the replacement is frequent, and the failure rate is high during processing
