Circumferential drilling device for machining agricultural machinery

Abstract

The invention discloses a circumferential drilling device for machining agricultural machinery. The circumferential drilling device includes a driving mechanism, a clamping mechanism, drilling mechanisms, and a cooling mechanism, the circumferential drilling device slides in a sliding groove through a sliding block so that two arc-shaped carrier blocks move in opposite directions, when the arc-shaped carrier blocks clamp a structural part, a bolt corresponds to a threaded hole, the arc-shaped carrier blocks are fixed through rotating the bolt, mounting and fixation of the structural part are facilitated, the arc-shaped carrier blocks support the structural part, a certain distance is between the structural part and a disk, the lengths of drill bits on the drilling mechanisms are arranged not to be in contact with the disk, the disk can be effectively protected from being damaged, the two drilling mechanisms are parallelly arranged, a hydraulic oil cylinder drives an ejector rod to move, the drill bit is driven by the motor to rotate, the ejector rod drives the drill bit to move downward, the drill bit is pressed down by the ejector rod, each time the disk rotates by a set angle, the structural part can be punched with two holes, time is saved, and the efficiency of drilling is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery processing, in particular to a circular drilling device for agricultural machinery processing. Background technique [0002] Agricultural machinery refers to various machinery used in the process of crop planting and animal husbandry production, as well as the primary processing and handling of agricultural and animal products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland drainage and irrigation machinery, crop harvesting machinery, agricultural product processing machinery, animal husbandry machinery and agricultural transportation machinery, etc. [0003] Parts of agricultural implements need to be drilled before being assembled. [0004] However, the existing peripheral drilling devices for processing agricultural machinery mainly h...

AI Technical Summary

Problems solved by technology

[0007] The object of the present invention is to provide a kind of circular drilling device for processing agricultural machinery, to solve the problem that the existing circular drilling device for processing agricultural machinery in the above-mentioned background technology is not only inconvenient when punching the circular structural parts of agricultural machinery. The structural parts are installed and fixed, and the drill bit is easy to damage the parts carrying the structural parts; the existing circular drilling device for agricultural machinery processing is not efficient in drilling circular structural parts of agricultural machinery.
