Description

Multipurpose Horizontal Deep Hole Drilling Machine

Technical field

The utility model relates to mechanical processing equipment, in particular to a multipurpose horizontal deep hole drilling machine, which is suitable for mold processing enterprises.

Background technique

In the prior art, a traditional horizontal deep hole drilling machine is mainly composed of a large column, a headstock bed and a base, a headstock, a guide seat, a support frame, a headstock bed lifting mechanism and a workbench. The headstock bed and the bed base are placed on the vertical guide rails of the large column, and are lifted by the headstock bed lifting mechanism placed on the large column. The workbench and the headstock bed form a T shape and are placed on the headstock bed the front of the body. The guide seat is fixed on the end of the headstock bed, facing the workbench. Several brackets are placed on the headstock bed, and the headstock is set on the guide rail of the headstock bed at the rear end of the support frame, and the headstock is driven to move left and right by the motor, the screw and the screw nut connected to it, so that it is installed on the headstock The gun drill on the top is supported by the support frame and guided by the guide seat to perform deep processing on the workpiece on the workbench. It has been proved by practice that the drilling machine has always had the following shortcomings: one is that it has a single function, and it can only perform deep hole processing and cannot do other processing work; the other is that because the headstock bed is fixed, the workpiece must be installed The position of the guide seat, when one surface is processed, the rotary workpiece table rotates 180°, the gun drill of the spindle box cannot directly process the other side, and the workpiece must be reinstalled to make it close to the guide seat, thus increasing the auxiliary time, that is, the Drilling machines are not suitable for using rotary tables; the third is that when the workpiece rotates at a certain angle and needs to process inclined holes, the drilling of inclined holes is limited because the guide seat cannot be close to the workpiece.

Contents of the invention

In order to solve the problems existing in the existing deep hole drilling machine, the utility model provides a multipurpose horizontal deep hole drilling machine. The drilling machine can not only drill straight holes, but also can drill inclined holes, and can easily mill the workpiece surface.

The above tasks are achieved in this way: the horizontal deep hole drilling machine includes a large column, a headstock bed, a bed base, a headstock, a feed mechanism consisting of a motor, a reducer, a screw, and a nut, and a guide seat , support frame, bed lifting mechanism and workbench, the headstock bed of this technical scheme is supported on the bed base by its guide rail and the guide groove of the bed base, and the headstock bed is provided with motor, deceleration There is a nut on the base of the machine bed to match the screw mandrel, and the guide seat is placed on the front end of the headstock bed with screws, and a taper hole for installing a milling cutter is provided at the front end of the headstock main shaft, and A transition sleeve that can be installed with a gun drill is provided on the taper hole.

The technical solution can also be further improved by taking the following measures:

A guide seat hanger is also provided on the front side of the large column, so that the removed guide seat can be hung on the guide seat hanger.

The support frame is changed to a movable type, which is characterized in that the fastening device on one side of the bottom end of the support frame is composed of an inlay, a base with a long hole and fastening screws, and the inlay is pressed laterally on the headstock through the screws On the side edge of the bed, the base is pressed upwards on the side edge of the headstock bed through its oblong hole through the screw. When the support frame needs to be removed, just loosen the two fastening screws, remove the inlay, and pull the base out along the oblong hole, then the support frame can be quickly taken out to match the use function of this drilling machine, reduce auxiliary time and improve efficiency.

Compared with the existing horizontal deep hole drill, the utility model has the following advantages:

1. Retain the functions of the existing horizontal deep hole drilling machine, and can drill deep holes with relatively large length and diameter;

2. The end face of the workpiece can be milled: remove the guide seat and support frame, install a milling cutter on the taper hole at the front end of the spindle box, and move the spindle box to the front end.

3. It can drill oblique holes on the workpiece: place the workpiece on the rotary table, rotate it to a certain angle, and then move the headstock bed so that the guide seat is close to the workpiece to drill.

4. When processing all sides of the workpiece, there is no need to reinstall the workpiece, which greatly saves auxiliary man-hours. When one surface of the workpiece is processed, turn the rotary table to the required processing surface, and then move the headstock bed so that the guide seat or the front end of the headstock is close to the surface of the workpiece.

In addition, the utility model also has the advantages that it can be implemented on the existing deep hole drilling machine, and the operation is simple.
