The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Example 1:
as shown in fig. 1, the boring tool of the present embodiment includes a tool body connecting member 3, a rough boring cutter head 1, a fine boring cutter head 2, and a slide bar 6. The bottom end of the cutter body connecting piece 3 is connected with a machine tool (not shown in the figure); the top end of the cutter body connecting piece 3 is detachably connected with the rough boring cutter head 1; the cutter head connecting piece 3 is provided with a through hole along the radial direction; the sliding rod 6 is in sliding fit with the through hole, and the sliding rod 6 is connected with a screw adjusting mechanism for driving the sliding rod to slide.
The spiral adjusting mechanism comprises a copper sleeve 4 and a screw rod 5; the copper bush 4 is fixedly connected with one end of the sliding rod 6, the copper bush 4 can be welded to one end of the sliding rod 6, and the copper bush can also be fixed at one end of the sliding rod 6 by screws; in this embodiment, as shown in fig. 1, a screw hole is formed at one end of the sliding rod 6 along the radial direction of the tool bit connecting member 3, an external thread connected to the screw hole of the sliding rod 6 is formed on the outer circumferential surface of the copper bush 4, the copper bush 4 is completely fixed to the sliding rod 6 by screwing the copper bush 4 into the screw hole of the sliding rod 6, and the copper bush 4 and the sliding rod 6 are completely fixed by using a bolt or a set screw or by destroying part of the external thread of the copper bush 4. The copper bush 4 is provided with an internal thread which is in threaded fit with the screw 5 along the sliding direction of the sliding rod 6; the screw rod 5 is rotationally connected with the cutter body connecting piece 3, and the rotating axis of the screw rod 5 is parallel to the sliding direction of the sliding rod 6. The rotary connection of the screw rod 5 and the cutter body connecting piece 3 can be realized through the prior art such as a bearing, specifically, the bearing is arranged at one end of the radial hole, the outer ring of the bearing is in interference fit with the hole wall of the radial hole, and the outer circular surface of the screw rod 5 is in interference fit with the inner ring of the bearing, so that the rotary connection of the screw rod 3 and the cutter body connecting piece 3 can be realized. In this embodiment, as shown in fig. 1, the radial hole is in a two-step shape, and one end of the screw rod 5 is provided with a nut which is located outside the cutter body connecting piece 3; a locking nut 7 in threaded connection with the screw rod 5 is arranged in the large hole of the radial hole, one end of the locking nut 7 abuts against the nut, the other end of the locking nut 7 is provided with a flange with the diameter larger than that of the small hole of the radial hole, and the gap between the flange and the nut is slightly larger than the depth of the small hole of the radial hole, so that the rotary connection between the screw rod 5 and the cutter body connecting piece 3 is realized. It should be noted that, because one end of the lock nut 7 abuts against the nut, and the diameter of the outer circular surface of the lock nut 7 between the flange and the nut is slightly smaller than the diameter of the small hole of the radial hole, when the screw rod 5 rotates, the lock nut 7 does not rotate relative to the screw rod 5. The cutter body connecting piece 3, the copper bush 4, the screw 5 and the sliding rod 6 constitute the adjusting structure of the embodiment.
It should be noted that, when the cross section of the sliding rod 6 and the cross section of the radial hole are both non-circular cross sections, no anti-rotation structure may be provided between the sliding rod 6 and the radial hole. When one of the cross section of the slide rod 6 and the cross section of the radial hole is a circular section, an anti-rotation structure needs to be provided. The rotation-preventing structure can be realized by using the prior art such as a plug pin, taking the cross section of the sliding rod 6 and the cross section of the radial hole as circular cross sections as an example, as shown in fig. 1 and 3, the outer circular surface of the sliding rod 6 is provided with a long groove 62 along the sliding direction of the sliding rod 6, the cutter body connecting part 3 is provided with a screw hole 31, the screw hole 31 is internally threaded with a set screw (not shown in the figure), and one end of the set screw extends into the long groove 62, so that rotation prevention can be realized. In this embodiment, as shown in fig. 3, the bottom of the long groove 62 is gradually inclined toward the center of the sliding rod 6 from the end of the copper bush 4 pointing to the fine boring tool bit 2, so as to avoid the tool back-off phenomenon of the fine boring tool bit 2 during machining, i.e. the fine boring tool bit 2 backs away from the machined hole.
The copper bush 4 is made of copper alloy, so that the thread matched with the screw rod 5 by the copper bush 4 has certain elasticity, and the thread matching between the screw rod 5 and the copper bush 4 is smoother and cannot be blocked.
Example 2:
the present embodiment differs from embodiment 1 in that a sliding guide structure is provided between the cutter body connecting member 3 and the rough boring cutter head 1, and the sliding direction of the rough boring cutter head 1 is parallel to the sliding direction of the sliding rod 6. In this way, the position of the rough boring cutter head 1 can be adjusted to increase the range of the machining bore diameter.
As shown in fig. 2 and 4, the sliding guide structure includes a first tooth structure 11 provided at the bottom of the rough boring head 1 and a second tooth structure 33 provided at the top of the cutter body connecting member 3 and positioned to cooperate with the first tooth structure.
Example 3:
as shown in fig. 2, the present embodiment is different from embodiment 1 in that the slide rod 6 is provided with a through positioning hole 61 along the radial direction thereof, and a cutter bar 8 is positioned and fitted in the positioning hole 61; a fixed connecting structure is arranged between the cutter bar 8 and the sliding rod 6, and one end of the cutter bar 8, which is far away from the sliding rod 6, is detachably connected with a boring blade 9; the top of the cutter body connecting piece 3 is provided with an avoiding groove 32 for avoiding the cutter bar. Therefore, the boring cutter can be used for processing small holes, so that the processing range of the boring cutter is enlarged.
As shown in fig. 2, the fixing and connecting structure includes a threaded hole 62 formed in the wall of the positioning hole 61 and a set screw (not shown) screwed into the threaded hole 62; one end of the threaded hole 62 penetrates the slide bar 6.
The present invention is not limited to the above-mentioned optional embodiments, and any other products in various forms can be obtained by anyone under the teaching of the present invention, and any changes in the shape or structure thereof, all the technical solutions falling within the scope of the present invention, are within the protection scope of the present invention.
