Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The present invention will be described in detail with reference to fig. 1.
Referring to fig. 1, the present invention includes a guiding extension rod 1, a round nut 2, an adjusting nut 3, a blocking cover 4, a thrust ball bearing 5, and a positioning sleeve 6. The cutter connecting section 1d is provided with a Morse taper hole 8, the Morse taper hole 8 can be matched with and provided with a plurality of cutters with Morse tapers, and the connection between the cutter connecting section 1d and the cutters can be in other forms, for example, the cutter connecting section 1d and the cutters are manufactured into a whole. The bearing mounting section 1c is in interference fit with the shaft ring 5a, the inner wall of the adjusting nut 3 is in clearance fit with the bearing mounting section 1c, one end of the adjusting nut 3 is pressed on the shaft ring 5a, and the other end of the adjusting nut is in threaded connection with the threaded connection section 1 b. The machining depth of the hole is adjusted by rotating the adjusting nut 3. The round nut 2 is screwed on the threaded connection section 1b for locking the position of the adjusting nut 3. One end of the locating sleeve 6 is in clearance fit with the bearing mounting section 1c and is used as a bearing seat of the thrust ball bearing 5 and is in interference fit with the seat ring 5b, the inner wall of the locating sleeve 6 is in clearance fit with the shaft ring 5a and the adjusting nut 3, the other end of the locating sleeve 6 is in threaded connection with the blocking cover 4, a blocking cover through hole is arranged in the middle of the blocking cover 4, the inner wall of the blocking cover through hole is in clearance fit with the adjusting nut 3, and the clearance between the end face of one end of the blocking cover 4 and the adjusting nut 3 is 0.1-0.2 mm. The tool needs to be matched with a drill clamp 7 for use, when a guide connecting rod 1 with a cutter drills to a preset depth of a machining hole, a positioning sleeve 6 just jacks against the shaft shoulder end face of a guide sleeve 7a of the drill clamp 7 to prevent the positioning sleeve 6 and a blanking cover 4 from axially moving and rotating, the positioning sleeve 6 transmits resistance to the guide connecting rod 1 through a thrust ball bearing 5, an adjusting nut 3 and a round nut 2, so that the guide connecting rod 1 and the cutter cannot axially feed, but the positioning sleeve 6, the blanking cover 4, the adjusting nut 3 and the guide connecting rod 1 have gaps, so that the rotation of the guide connecting rod 1 and the cutter is not influenced.
When the tool is used, the connecting section 1a of the machine tool is fixed on a rotating shaft of the machine tool, the round nut 2 and the adjusting nut 3 are rotated during drilling, a hole which is relatively shallow compared with the required size is pre-drilled, then the size of the pre-drilled hole is measured by a measuring tool, the number of turns to be screwed of the adjusting nut 3 is determined according to the difference between the size of the pre-drilled hole and the required size and the thread pitch of the threaded connecting section 1b, and after the adjusting nut 3 is adjusted, the round nut 2 is used for locking the position of the adjusting nut 3. When the drill jig is machined again, when the required size is achieved, the positioning sleeve 6 just touches the guide sleeve 7a of the drill jig 7, and the guide sleeve 7a prevents the guide connecting rod 1 and the cutter from axially feeding but does not influence the rotation of the guide connecting rod 1 and the cutter. The adjusting nut 3 does not need to be screwed when the holes with the same size are machined for the second time, and the depth of the holes with higher precision can be machined once after the workpiece is placed at the fixed position.
