Problems solved by technology

[0002] Drilling and tapping combination machine tool is a device used for tapping and expanding the inside of the workpiece. The workpiece processing position is drilled through the male drilling machine, and then the drilling position is tapped by the tapping machine. The size of the drilling hole is the same as the tapping tap. The inner diameter is the same, and the tap will discharge the tapping chips through the outer thread groove during the tapping process. When tapping the cast workpiece, the tapping chips will become powder and be discharged from the thread groove smoothly, but when tapping the steel workpiece Tapping chips will form a continuous strip of steel wire, and the steel wire will be wound into a circle inside the thread, resulting in unsmooth chip removal, causing wear on the surface of the tap and increasing the friction of the tap, resulting in increased torque on the tap, and finally the tap is stuck The torque rises in a straight line and the overall fracture

Embodiment 1

[0024] as attached figure 1 to attach image 3 Shown:

[0025] The invention provides a combined drilling and tapping machine tool, the structure of which includes a base 1, a processing table 2, a protective cover 3, a driving machine 4, a drilling machine 5, and a tapping machine 6, and the upper side of the base 1 is connected with the lower side of the processing table 2 by bolts , the protective cover 3 is welded and connected to the upper side of the processing table 2, the driving machine 4 is embedded and connected to the upper side of the protective cover 3, the drilling machine 5 is embedded and connected to the upper side of the protective cover 3, and the tapping machine 6 It is embedded and connected with the upper right end of the protective cover 3. The tapping machine 6 includes a liquid tank 61, a transmission column 62, a liquid supply pipe 63, a liquid supply head 64, and a tapping head 65. The liquid tank 61 and the protective cover 3 The inner side of th...

Embodiment 2

[0030] as attached Figure 4 to attach Figure 7 Shown:

[0031] Wherein, the tapping head 65 includes a main block 651, a sliding sleeve 652, a tap 653, and a liquid injection port 654. The main block 651 is welded to the lower end of the liquid supply head 64, and the sliding sleeve 652 is arranged on the liquid supply head 64. On the outer side of the lower end, the tap 653 is embedded and connected to the lower end of the liquid supply head 64, and the liquid injection port 654 is embedded and connected to the lower end of the tap 653. The liquid injection port 654 is located at the lower end of the tap 653, and the number is three. The center of the cone 653 is distributed in a ring shape, so that the liquid ejected from the liquid injection port 654 can rise evenly and impact the iron filings.

[0032] Wherein, the tap 653 includes a chip removal groove 53a, a cutting cone 53b, and a main rod 53c, the chip removal groove 53a is embedded and connected to the outside of ...

Abstract

The invention discloses a drilling and tapping combined machine tool. The drilling and tapping combined machine tool structurally comprises a base, a machining table, a protective cover, a driving machine, a drilling machine and a tapping machine, the upper side of the base is in bolted connection with the lower side of the machining table, the protective cover is in welded connection with the upper side of the machining table, the driving machine is fixedly connected with the upper side of the protective cover in an embedded mode, and the drilling machine is fixedly connected with the upper side of the protective cover in an embedded mode. The tapping machine is fixedly connected with the right end of the upper side of the protective cover in an embedded mode, the tapping machine comprises a liquid tank, a transmission column, a liquid supply pipe, a liquid supply head and a tapping head, the liquid supply pipe conveys cutting liquid to flush the tapping head through the liquid supplyhead, when the cutting liquid is conveyed, the cutting liquid of a liquid guide channel on the inner side of an outer cover can stretch a spring to enable a movable block to move downwards, the friction force of iron chips to the outer side of the tapping head is reduced, and the chip removal capacity of the tapping head is improved; and long-strip-shaped iron chips on the outer side of a screw tap can be cleaned away by outer blades, a steel wire smoothly flows out in a chip removal groove, the chip removal smoothness is improved, and the friction force caused by the surface of the screw tapis reduced.
