Abstract

The utility model relates to a device that is used for installing a boring hole on a horizontal lathe. The device aims at solving the problem that a boring bar is difficult to lift and drop when the boring hole is installed on the horizontal lathe and the like. The device consists of three parts: a telescoping and swinging arm, a boring head and boring bar lifting mechanism and a workpiece transverse moving mechanism. The device is characterized in that the telescoping and swinging arm is formed by the sequential installation and connection of a coupling (2), a spline sleeve (3), a spline shaft (4) and a coupling (5). One end of the spline sleeve (3) is arranged on the coupling (2), one end of the spline shaft (4) is arranged on the coupling (5), and the other end of the spline shaft (4) is assembled with the other end of the spline sleeve (3) by the spline shaft. Because the coupling (2) and the coupling (5) can swing and the spline shaft (4) can slide in the spline sleeve (3), the mechanism can be telescoped and swung both. The telescoping and swinging arm mechanism can solve the power transmission problem when the boring rod lifts and drops during the boring hole installation process. The boring hole device can be used for installing the boring hole on the horizontal lathe and also used for processing a horizontal milling.

Description

The device that is used for bore hole on horizontal lathe

Technical field

The utility model is the device that is used for bore hole on horizontal lathe, and it can be implemented in bore hole on the horizontal lathe.

Background technology

Known lathe bore hole technology is the main spindle box by the lifting lathe, and axle supporting on the lifting tailstock accordingly, makes boring bar obtain lifting.Though this technical scheme can be carried out bore hole on lathe,, therefore be difficult on the horizontal lathe of typing, implement because the lifting of main spindle box must make the centre-to-centre spacing of belt pulley and the centre-to-centre spacing of change gear change thereupon.

Summary of the invention

In order to overcome the deficiency of known technology, the utility model provides a kind of new boring device.It can carry out bore hole to workpiece on horizontal lathe, do not change any structure of lathe again.

At first, the main motion during bore hole is from lathe spindle.It is characterized in that: lathe spindle finally drives the boring bar rotation by telescopic oscillating arm, boring head main shaft, and the principal cutting movement during bore hole realizes.The telescopic oscillating arm is made of a key cover, a key axle and two shaft couplings, and an end of key cover is installed on the shaft coupling, and an end of key axle is installed on another shaft coupling, and the other end of key axle is by the other end of its key axle load key cover.Because two shaft couplings can be swung, the key axle can slide in the key cover again, so this mechanism not only can stretch but also can swing.

In addition, want bore hole, boring bar can be moved on short transverse, to seek by the height and position of bore hole.The utility model utilizes guide pillar, lifting platform, screw rod and nut to make boring head and boring bar lifting.Guide pillar is installed in by saddle plate on the lathe bed of lathe, and lifting platform is enclosed within on the guide pillar by the face of cylinder, the guide effect when so just having played lifting.And relatively rotating between screw rod and the nut can make boring head, boring bar together with lifting platform one lifting.Guide pillar, saddle plate, lifting platform and upper beam have formed a tower structure, have increased the stability of this device.

Equally, want bore hole, workpiece must laterally can move, to seek by bore hole in horizontal position.The utility model is to realize by the horizontal mobile leading screw that rotates lathe.Before the bore hole, shake the horizontal mobile handgrip of lathe earlier, the horizontal mobile pallet of lathe (middle supporting plate) is shaken out and unloads, install the workbench that has T type groove then.Just be installed on this workbench by borer spare, and seek by the lateral attitude of bore hole by shaking horizontal mobile handgrip.

Length feed is to rely on vertically moving of lathe big palette to realize during bore hole.

The beneficial effects of the utility model are: it can not only carry out bore hole to workpiece on horizontal lathe, but also can carry out Milling Process.Can carry out end mill, also can crouch and mill,, can also be used to the mill teeth wheel if be equipped with dividing head.

Description of drawings

Fig. 1 is the general assembly drawing of this lathe boring device;

Fig. 2 is that K among Fig. 1 is to view.

Code name implication among the figure: 1 is mounted in the three-jaw on the lathe spindle, and the 2nd, shaft coupling, the 3rd, key cover, the 4th, key axle, the 5th, shaft coupling, the 6th, lifting platform, the 7th, guide pillar, the 8th, handwheel, the 9th, the nut that is connected with handwheel 8, the 10th, screw rod, the 11st, boring head, the 12nd, boring head main shaft, the 13rd, straight end-face key, the 14th, boring bar, the 15th, cutter head, the 16th, bearing, the 17th, put the beams in place, the 18th, saddle plate, the 19th, lathe bed, the 20th, workbench, the 21st, the handgrip that workbench is laterally moved, the 22nd, the big palette of lathe.

The specific embodiment

---key cover 3 rotations---key axle 4 rotations---shaft coupling 5 rotations---boring head main shaft 12 rotations that in Fig. 1, the lathe spindle rotation drives three-jaw 1 rotation, and the rotation of three-jaw 1 drives shaft coupling 2 rotations successively.And boring head main shaft 12 drives boring bar 14 rotations by straight end-face key 13, and the other end of boring bar 14 is contained in the bearing 16.Cutter head 15 has just formed the principal cutting movement to workpiece bore under the drive of boring bar 14 like this.As can be seen from the figure, an end of key cover 3 is installed on the shaft coupling 2, and an end of key axle 4 is installed on the shaft coupling 5.It can also be seen that from figure the other end of key axle 4 is assembled together by the other end of its key axle with key cover 3.Because shaft coupling 2 and shaft coupling 5 can be swung, and key axle 4 can overlap slip in 3 at key, so these elements have just been formed the telescopic oscillating arm.

The lifting of boring bar 14 is achieved in that referring to accompanying drawing 2, rotates handwheel 8, makes nut 9 rotations.Nut 9 is by 17 rests of putting the beams in place.Because screw rod 10 can not rotate, thus axially lifting of screw rod 10, and drive boring head 11 together with lifting platform 6 one liftings, the lifting of boring bar 14 is achieved.

The level of workpiece is traversing during bore hole laterally moves workbench 20 to realize by shaking the horizontal mobile handgrip 21 of lathe.

Long feed during bore hole is that the big palette 22 by lathe moves realization, can be motor-driven, and also can be manual.

Claims

1, a kind of device that is used for bore hole on horizontal lathe, by boring head, boring bar, guide pillar, lifting platform, saddle plate, upper beam and workbench connection being installed forms, it is characterized in that: it has the telescopic oscillating arm, the telescopic oscillating arm is made of shaft coupling (2), key cover (3), key axle (4) and shaft coupling (5), one end of key cover (3) is installed on the shaft coupling (2), one end of key axle (4) is installed on the shaft coupling (5), and the other end of key axle (4) is assembled together by the other end of its key axle with key cover (3).
