Multi-axis drilling machine with adjustable interval

Abstract

The invention relates to a multi-axis drilling machine with an adjustable interval, which comprises a machine body, a control box, a base, a workbench, a main motor and a spindle box, wherein a workbench lifting mechanism is arranged between the workbench and the base; the spindle box is arranged on the machine body and above the workbench; the spindle box is internally provided with a universal joint; the upper end of the universal joint is connected with the main motor through a gear or a belt wheel, and the lower end of the universal joint is connected with a drill bit spindle; the bottom of the spindle box is sequentially provided with a fixed regulating plate and a rotary regulating plate; a radial slotted hole is arranged on the fixed regulating plate, and an involute-shaped slotted hole corresponding to the radial regulating slotted hole is arranged on the rotary regulating plate; the periphery of the involute-shaped slotted hole is provided with positioning slotted holes; the drill bit spindle is arranged in the radial slotted hole and the involute-shaped slotted hole through a bearing; and fastening screws are arranged in the positioning slotted holes and connected with the fixed regulating plate. The machine has the characteristics of convenience of regulation and high precision.

Description

technical field [0001] The invention relates to mechanical processing equipment, in particular to a multi-axis drilling machine with adjustable spacing. Background technique [0002] At present, the common drilling machine is usually a single-axis drilling machine, which mainly includes the body, base, worktable, main motor, spindle box, etc. The main motor drives the spindle box, and the drilling operation is completed by moving the worktable up and down through the oil cylinder. Yes, the multi-axis drilling machine needs to move the parts multiple times to complete the work on the part. The operation is complicated, the precision is not high, and the efficiency is low. For this reason, there are also multi-axis drilling machines in the market. The structure of the multi-axis drilling machine is the biggest difference from the single-axis drilling machine. It is connected with the main motor and each spindle through gears and universal joints, so that multiple spindles can ...

[0002] At present, the common drilling machine is usually a single-axis drilling machine, which mainly includes the body, base, worktable, main motor, spindle box, etc. The main motor drives the spindle box, and the drilling operation is completed by moving the worktable up and down through the oil cylinder. Yes, the multi-axis drilling machine needs to move the parts multiple times to complete the work on the part. The operation is complicated, the precision is not high, and the efficiency is low. For this reason, there are also multi-axis drilling machines in the market. The structure of the multi-axis drilling machine is the biggest difference from the single-axis drilling machine. It is connected with the main motor and each spindle through gears and universal joints, so that multiple spindles can work synchronously, and each spindle is evenly distributed in a circular shape. The current multi-axis drilling machine, when the hole pitch of the machined parts changes, The adjustment of the spacing is very inconvenient. The adjustment of the spacing fixes each spindle in the adjustment hole of the adjustment platform of the spindle through the bearing. The defect of inconvenient adjustment. At present, this kind of multi-axis drilling machine is mainly used for processing special parts, and it cannot adjust the distance of each spindle well according to the change of the processed parts.
