Perforating device for small object machining

Abstract

The invention discloses a perforating device for small object machining in the technical field of machining. The perforating device comprises a base and a support, clamping grooves are symmetrically formed in the upper portions of the left side face and the right side face of the base correspondingly, bottom protruding blocks on the left side and the right side of the support are clamped in the clamping grooves correspondingly, a first lead screw is arranged inside the clamping groove in the left side, the middle of the first lead screw penetrates through the bottom protruding block on the left side of the support in a threaded connection mode, and two ends of the first lead screw penetrate through the base through bearing connection, a sliding rod is arranged in the clamping groove in theright side. According to the perforating device, lifting of a perforating machine is achieved through a connecting rod mechanism, by adoption of a scale column with scales, the perforating machine isdriven to drill holes and reset, the perforating precision can be accurately controlled, the problems that in prior art, the perforating progress is inconvenient to observe, and the perforating precision is difficult to control are solved, movement of the perforating machine in multiple directions is achieved through the arranged lead screws, the perforating device can be fixed to a table top forperforating through the matched structure of a jacking lead screw and a pressing plate, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a punching device for processing small objects. Background technique [0002] There are many kinds of mechanical equipment. When the mechanical equipment is running, some of its parts and even itself can perform different forms of mechanical movement. Mechanical equipment is composed of driving device, transmission device, transmission device, working device, braking device, protective device, lubrication system, cooling system and other parts. Drilling machine is a kind of mechanical equipment. Drilling machine refers to the use of Harder, sharper tools A general term for machines and devices that leave cylindrical holes or holes in a target by means of rotary cutting or rotary extrusion. Also known as drilling rigs, punching machines, drilling machines, through-hole machines, etc. To achieve the expected effect by processing precision parts, general mechanical d...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of punching device that is used for small object processing, in order to solve above-mentioned background technology through the mechanical mechanism such as screw mandrel rotation to realize the lift of the drill bit, the structure is still comparatively complicated, the punching speed is relatively slow, can not Flexible and fast replacement of the punching parts, and the punching position is single, and the position of the punching parts must be disassembled and adjusted continuously. The operation is cumbersome and a lot of time is wasted. The bottom cavity formed by the L-shaped bracket is used to place the punching parts. It is inconvenient to install the punching parts, and the progress of the punching is inconvenient to observe, and the punching accuracy cannot be controlled
