Rocker arm and clamping mechanism of digital display type radial drilling machine

Abstract

A rocker arm and clamping mechanism of a digital display type radial drilling machine comprises a rocker arm, a pushing shaft, a piston, a cam, a support, an oil cylinder, an oil cylinder head, a clamping pressing plate, a pull rod, a lever and a hinging shaft. The rocker arm is provided with the pull rod and connected with the clamping pressing plate, the lever is fixed to the rocker arm through the hinging shaft, and the rocker arm is provided with the pushing shaft and the support; the oil cylinder is mounted on the support, the piston and the cam are mounted in the oil cylinder, and the oil cylinder head is mounted on the oil cylinder. According to the working principle, the rocker arm is mounted on a guide rail type outer rectangular post A and moves up and down along the guide rail type outer rectangular post A, and the guiding precision of the rocker arm and the guide rail type outer rectangular post A is guaranteed. According to the rocker arm and clamping mechanism, stepless speed changing of a spindle can be achieved under the non-halt condition, and working positions can be displayed through figures and numbers; the guiding precision of a guide rail is high, the spindle has a limiting function and is flexible and reliable, and a control system is advanced; the rocker arm and clamping mechanism is simple and reasonable in structure, convenient and quick to operate and high in working efficiency and can be applied to the machining industry.

Description

technical field [0001] The invention relates to a rocker arm and a clamping mechanism of a digital display radial arm drilling machine in the machining 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 dr...

AI Technical Summary

Problems solved by technology

[0003] There are still many deficiencies in the rocker arm and clamping mechanism of the radial drilling machine. The guiding accuracy of the guide rail is poor, the spindle has no limit function, and the guide rail structure is still difficult to repair after wear and tear. Poor performance, low strength and rigidity, low transmission accuracy, short service life and high failure rate
