Linear type multiple row horizontal-type-like double-face machining multiple spindles drilling machine

Abstract

The invention belongs to the technical field of machining equipment, in particular relates a linear type multiple row horizontal-type-like double-face machining multiple spindles drilling machine. The drilling machine comprises a common-base, a machine body, workbenches, a clamp and a drilling hole unit, the drilling hole unit is longitudinally and centrally installed along the top surface of the common-base; two workbenches are respectively installed on the machine body of two longitudinal ends of the common-base, and a workbench longitudinal reciprocating movement mechanism, a workbench lateral reciprocating movement mechanism and a workbench lifting movement mechanism are arranged inside the machine body from top to bottom; the clamp comprises a support and a clamping element; multi-layer transverse shelves are arranged on the support from top to bottom, a plurality of clamping elements are arranged on each transverse shelf; the drilling hole unit comprises spindles, drills, a gear box and a driving mechanism, the spindles are evenly distributed and installed in the gear box from top to bottom in a multi-row manner, two adjacent rows of spindles are arranged from top to bottom in a staggering manner, and the extending directions of the drills are opposite, the driving mechanism comprises a plurality of gears which are engaged with one another to carry out transimission, a main drive mechanism and a power mechanism. The linear type multiple row horizontal-type-like double-face machining multiple spindle drilling machine can processes rows of holes which are fixed in intervals and hole diameter on multiple workpieces to be processed, the time and labor are saved, the processing efficiency is high and the machining is precise.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing equipment, and in particular relates to a linear multi-row horizontal double-sided processing multi-axis drilling machine, which is especially suitable for opening holes in rectangular air duct angle steel flange angle steel parts. Background technique [0002] Angle steel flange ventilation pipe is a traditional form of ventilation pipe production. The angle steel flange air duct has the characteristics of a wide range of applications, and has an irreplaceable position in the air duct with a side length longer than one meter (especially greater than two meters). Especially in dust removal system, pipeline transportation system, fire prevention and smoke prevention system and ventilation engineering system, the advantages of angle steel flange air duct are more prominent. In order to reduce the production cost of angle steel flanges and improve production efficiency, there are matur...

Problems solved by technology

At present, the existing ordinary desktop drilling machine for opening holes is composed of a motor, a speed change mechanism, a feed mechanism and a frame, and can only drill one hole at a time. When drilling a single-hole machine tool, it is necessary to open holes one by one and reposition multiple times. There are bound to be problems such as inaccurate spacing, low machining hole position accuracy, and large hole spacing error. Therefore, the processing efficiency is low and the pass rate of workpiece quality is low.
