Description

A Vertical Small CNC Drilling Machine

technical field

The utility model relates to a numerical control drilling machine, in particular to a vertical small numerical control drilling machine.

Background technique

Drilling machine refers to a machine tool that mainly uses a drill bit to process holes in a workpiece. Generally, the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. The drilling machine has a simple structure and relatively low machining accuracy. It can drill through holes and blind holes, replace special tools, expand, countersink, ream or tap. During the machining process, the workpiece does not move, let the tool move, align the center of the tool with the center of the hole, and make the tool rotate (main movement). The characteristic of the drilling machine is that the workpiece is fixed and the tool rotates. At present, when there are many end faces of the workpiece, the iron filings generated during the machining process are splashed everywhere, making it difficult to collect, and the safety problem cannot be effectively guaranteed.

Utility model content

In order to achieve the above object, the utility model provides the following technical solutions:

A vertical small CNC drilling machine, comprising a platform, a machine head, a spindle structure and a workbench, a base is arranged above the platform, a column is vertically fixed at the rear of the base, a machine head is installed on the upper end of the column, and a machine head is installed inside the machine head. There is a main shaft structure; the main shaft structure includes a sleeve and a main shaft, and the middle hollow ball screw for controlling feed is arranged in the sleeve, and a synchronous pulley is arranged on the middle hollow ball screw; a drill bit is connected under the main shaft structure; the base There is a horizontal guide rail on the top, and a worktable for clamping workpieces is slid on the horizontal guide rail. A moving servo motor is installed on the right side of the base. The power output end of the moving servo motor is connected with a drive screw through a coupling and coaxial transmission. , the driving screw is parallel to the horizontal guide rail, the driving screw passes through the workbench and is threadedly connected with the workbench.

Further, the main shaft is provided with bearings and nuts for positioning.

Further, a chip receiving hopper with an open top is provided under the left side of the workbench, one side of the chip receiving hopper is connected to a chip removal machine, and the inlet of the chip removal machine communicates with the bottom of the chip receiving hopper.

Compared with the prior art, when the utility model works, the rotation of the synchronous pulley drives the middle hollow ball screw to feed, thereby driving the main shaft and the sleeve to move up and down in the guide sleeve; the sleeve is provided with a guide sleeve, which adopts The guide sleeve with high strength and toughness solves the problem of wear resistance of the sleeve and the spindle box, and solves the problem of the parallelism of the vertical movement of the spindle sleeve to the spindle axis; the spindle is equipped with a positioning bearing And the nut, the spindle is equipped with a radially positioned bearing, which is tightened by a nut, which solves the problem of the radial runout of the distal end of the spindle taper hole axis; The chips are collected by the chip receiving hopper to the chip conveyor, and then transported by the chip conveyor to the chip collector; this not only improves the work efficiency, but also makes the working environment cleaner and the safety issues are effectively guaranteed.
