For example, in the stage of milling the end plate of the wing finish machining No. 2 rib, multiple apertures such as phi 18, phi 20, phi 22, phi 24 and the like are required to be countersunk, and then the countersunk bolts are used for pre-tightening to mill the No. 2 rib. The following problems exist in this process:
1) The cutting amount is large, the deflection of the pneumatic drill is serious, and the countersink quality is poor;
2) The guide rod is large in size, and clamping on the pneumatic drill is not firm;
3) The torque force is large, the operation skill requirement is high, and the labor intensity is high;
the countersink drill with multiple apertures needs to be repeatedly replaced, and is time-consuming, labor-consuming and low in efficiency.

The utility model aims to: aiming at the characteristics of countersink of a large-size hole, the utility model provides a machine countersink tool with a detachable large-size hole guide head, which adopts a two-section structure of a quick-change guide head and a cutting tool, and only needs to change the quick-change guide head when countersink is carried out on holes with different specifications, and a clamping handle can be clamped on a tool handle of a machine tool, so that the machine tool countersink tool has the capability of being used. Solves the problems of unsmooth clamping, serious deflection, poor dimple quality, high operation strength, low efficiency and the like of the pneumatic drill when aiming at the large-aperture dimple.
The technical scheme is as follows:
the large-aperture hole countersinking tool for the machine with the replaceable guide head comprises a cutting tool and a quick-change guide head, wherein the head of the cutting tool is provided with a bolt hole, the quick-change guide head is provided with external threads, and the quick-change guide head is connected with the head of the cutting tool through threads.
Further, the quick-change guide head comprises a screw rod and a guide rod, the screw rod is in threaded fit with the bolt hole, and the guide rod is provided with various specifications according to the aperture of the hole to be processed.
Further, a clearance of 0.5mm is formed between the rear end face of the guide rod and the cutting tool.
Further, the lower end face of the guide rod is rounded, the side wall is polished, and lubricating oil is coated.
Further, the guide rod is provided with an inner hexagonal hole.
Further, the surface of the cutting part of the cutting tool is coated with lubricating oil.
Further, the handle end of the cutting tool is connected to a numerically controlled machine tool handle.
The beneficial effects are that:
the utility model provides a countersink tool for a large-aperture guide head detachable machine, which has the characteristics of replaceable guide head and capability of being matched with a machine tool. The guide heads with different specifications are only required to be replaced when the large aperture Kong Huowo with different specifications is formed. The portable electric heating device has the advantages of convenience, rapidness, small volume, exquisite structure, simple use method and wide applicability. Solves the problems of poor quality, high operation strength, low efficiency and the like of the large aperture Kong Huowo.

Wherein: 1. cutting tool, 2, quick change guide head.
The specific embodiment is as follows:
as shown in fig. 1, 2, 3 and 4, a countersink tool for a large-aperture guide head detachable machine is provided, and comprises an assembly 1, a cutting tool 2 and a quick-change guide head.
As shown in fig. 4, the cutting tool 1 includes a tapered clamping handle and a countersunk cutting portion. The clamping handle can be provided with corresponding length and taper according to the clamping requirement of the tool handle of the machine tool. And a standard threaded interface connected with the quick-change guide head is arranged below the countersink cutting part, and the rotation direction of the threads is consistent with the rotation direction of the machine tool.
As shown in fig. 3, the quick-change guide head 2 is composed of two parts, namely a guide rod and a screw. The guide rod main body is cylindrical, the diameter can adopt a plurality of different specifications according to the difference of bolt hole diameters, the lower end face of the cylinder is rounded, the side wall adopts polishing treatment, lubricating oil is coated, the surface is smooth, and the hole wall is not scratched during use. The lower end face of the quick-change guide head 2 is provided with an internal hexagonal structure, the internal hexagonal structure can be matched with an internal hexagonal wrench, the upper part of the quick-change guide head 2 is provided with a screw structure, a screw can be screwed into a threaded hole below a cutting tool, the screw is of standard design, guide heads of different specifications all adopt the same screw diameter, screw thread type and screw screwing direction, and the screw specification above the quick-change guide head 2 is matched with the screw hole specification below the cutting tool 1.
As shown in fig. 1 and 2, the quick-change guide head 2 and the cutting tool 1 are in quick connection in a threaded manner. A gap of 0.5mm is formed between the joint surface of the quick-change guide head 2 and the cutting tool 1, so that the cutting edge abrasion caused by too tight fit of the quick-change guide head 2 and the cutting tool 1 can be prevented. The spiral direction is consistent with the rotating direction of the main shaft of the bed when the countersink is carried out, so that the quick-change guide head is ensured not to loose when being stressed. The inner hexagonal hole at the lower end of the quick-change guide head 2 can be matched with an inner hexagonal wrench to realize reliable connection and quick decomposition of the quick-change guide head 2 and the cutting tool 1. The quick-change guide head 2 of the large-aperture hole countersinking tool for the guide head replaceable machine is in standard threaded connection with the cutting tool 1, and when the large apertures Kong Huowo with different specifications are formed, only the quick-change guide head with different diameters is needed to be replaced by using an internal hexagonal wrench, and the whole cutting tool is not needed to be replaced.
When the tool is used, the cutting tool 1 is clamped on the tool handle of the machine tool, then the quick-change guide head 2 with corresponding specification is selected according to the aperture size, the screw rod of the quick-change guide head 2 is screwed into the threaded hole below the cutting tool 1 under the assistance of the internal hexagonal wrench, and the cutting part of the cutting tool 1 and the surface of the quick-change guide head 2 are coated with lubricating oil. Selecting proper machining parameters, finishing tool setting operation through a machine tool handle, finishing the socket setting operation by using a large-aperture hole socket setting tool for a machine tool with a replaceable guide head by using a machine tool, repeating the process until the socket setting operation of large-size holes with the same specification is finished, shutting down the machine tool, dismantling the quick-change guide head by using an internal hexagonal wrench, replacing the quick-change guide heads with other sizes according to the aperture size, and repeating the process, and finishing the socket setting of holes with different diameters by using the same cutter.
