Adjustable pitch multi-head drill

Abstract

The invention aims to provide a multi-head drill with adjustable hole pitch, which is structurally characterized in that an input shaft is connected with an input supporting bearing, a main transmission bearing I, a driving gear, an input shaft key, a spacer bush and a snap spring, and is fixed on a box body through a box cover; an output shaft is fixed on a rocker arm through a rocker arm bearing II, a baffle ring, a spacer bush, a rocker arm spacer bush, a driven gear, a rocker arm bearing I and an output shaft snap spring to form a rocker arm assembly; an intermediate drive gear is supported on a middle supporting shaft through an intermediate drive gear spacer bush, a rolling needle, a middle supporting shaft spacer bush I and a middle supporting shaft spacer bush II; the rocker arm assembly is fastened on a main shaft box through the middle supporting shaft and screw nuts; and a main transmission gear and the intermediate drive gear are mutually engaged and the intermediate drive gear and the driven gear are mutually engaged.

Description

technical field [0001] The invention relates to a multi-head drill with adjustable hole distance, which belongs to the field of machinery. Background technique [0002] At present, in the field of multi-head drilling rigs in my country, the main traditional models are fixed-hole-pitch drilling, and are mainly used for large-size hole-pitch drilling. However, with the rapid development of the machinery industry, the original multi-head drilling Functions are far from meeting the actual needs of users for diversified and flexible processing. It is necessary to invent a multi-head drill with adjustable hole spacing. For this reason, we have invented a multi-head drill device with adjustable hole spacing to solve the problem of The problems of high production cost and production flexibility of multi-head drilling machine can not be solved. Contents of the invention [0003] The object of the present invention is to provide a multi-head drilling device with adjustable hole dista...
