Abstract

The utility model is a multi-purpose horizontal deep-hole drilling machine, which is the improvement of the current horizontal deep-hole drilling machine. The utility model is characterized in that the headstock bed utilizes the lead rail and the guide slot positioned at the bed base to support the bed base; the headstock bed is provided with an electrical motor, a decelerator and a screw mandrel; a nut working in with the screw at the bed base and a guide holder are arranged at front end of the bed base through a bold. A taper hole is positioned at the front end of the headstock principal axis and the taper hole can be installed with a milling cutter. A taper reduction sleeve that can install a gun drill is positioned at the taper hole. Compared with the current deep-hole drilling machine, the utility model can not only gun drill but also run milling and angled holes. The utility model saves reduces the man hours and improves the efficiency greatly for processing a plurality of sides, which does not require reinstalling the work-pieces. The utility model is particularly applied to die processing units.

Description

The multipurpose horizontal deephole drilling machine

Affiliated technical field

The utility model relates to machining equipment, and particularly a kind of multipurpose horizontal deephole drilling machine is fit to Mould Machining enterprise and uses.

Background technology

In the prior art, the horizontal deephole drilling machine of traditional type mainly is made up of big column, headstock bed and base, main spindle box, guide holder, bearing support, headstock bed elevating mechanism and workbench.Headstock bed and lathe bed base is placed on the vertical guide of big column, and by placing the headstock bed elevating mechanism on the big column to come lifting, workbench is placed in headstock bed front end with the headstock bed T of one-tenth shape.Guide holder is fixed in headstock bed termination, over against workbench.Several supports be placed in headstock bed on, main spindle box is arranged on the headstock bed guide rail in bearing support rear end, and by motor, screw mandrel and the feed screw nut's drive shaft case move left and right that is attached thereto make the drill gun that is installed on the main spindle box carry out deep processing in the supporting of bearing support and the guiding of guide holder to the workpiece on the workbench.Through facts have proved, there is following weak point in this drilling machine always: first function singleness, carry out deep hole machining only, and can not do other processing work; Its two since headstock bed be to fix, so workpiece must be in the guide holder position when installing, when processing a face, rotary work piece platform Rotate 180 °, the drill gun of main spindle box can't directly be processed another side, workpiece must be reinstalled, and makes it near guide holder, therefore increased non-cutting time, that is this drilling machine is not suitable for using panoramic table; It three is that workpiece rotates to an angle when needing the processing inclined hole, because of guide holder can't be restricted rat holing near workpiece.

Summary of the invention

In order to solve the problem that existing deep hole drilling machine exists, the utility model provides a kind of multipurpose horizontal deephole drilling machine.This drilling machine not only can bore straight hole, but and rat holing, and can carry out Milling Process to surface of the work very easily.

Above-mentioned task realizes by this way: this horizontal deephole drilling machine comprises big column, headstock bed, lathe bed base, main spindle box, by motor, decelerator and screw mandrel, the delivering gear that nut is formed, guide holder, bearing support, lathe bed elevating mechanism and workbench, the headstock bed of the technical program is to cooperate with the guide groove of lathe bed base with its guide rail to be supported on the lathe bed base, and on headstock bed, be provided with motor, decelerator and screw mandrel, on lathe bed base, be provided with and the screw mandrel nut engaged, guide holder is placed in headstock bed front end with screw, front end at headstock spindle is provided with a taper hole that milling cutter can be installed, and is provided with a spacer shell that drill gun can be installed on taper hole.

The technical program also can take following measure further perfect:

The guide holder of unloading down also is provided with a guide holder hanger at big column leading flank, so that can be suspended on the guide holder hanger.

Bearing support changes packaged type into, it is characterized in that fastener in a side of bearing support bottom is by a panel, a base and a trip bolt that has slotted hole is formed, panel laterally presses on headstock bed lateral edges by screw, and base through screws is passed its slotted hole and upwards pressed on the headstock bed incline.In the time of need unloading lower supporting frame,, take off panel, and base is pulled out along slotted hole, can take out bearing support fast,, reduce non-cutting time, raise the efficiency to cooperate the function of use of this drilling machine as long as unclamp two trip bolts.

The utility model is compared with existing horizontal depth drill, has following advantage:

1. keep the function of existing horizontal deephole drilling machine, can bore the bigger deep hole of draw ratio;

2. can carry out Milling Process to workpiece end face: guide holder and bearing support are unloaded, on the taper hole of headstock spindle front end, load onto milling cutter, and main spindle box is moved to front end just can.

3. can be to the workpiece rat holing: workpiece is positioned on the panoramic table, rotates to certain angle, move headstock bedly then, guide holder just can be holed near workpiece.

4. can add man-hour to each face of workpiece, not need to reinstall workpiece, save unproductive time greatly.After a face completion of processing of workpiece, rotate panoramic table to required machined surface, mobile headstock bed again, guide holder or main spindle box front end just can near surface of the work.

In addition, the utility model also has and can implement advantage simple to operate at existing deep hole drilling machine.
