Detailed Description

The present invention is further illustrated by the following examples, but is not limited thereby in the scope of the examples described below.

Referring to fig. 2, an embodiment of the present invention provides a boring tool holder for use in an apparatus for boring a marine sea water pipe. The boring holder includes a mounting assembly 10, a first adjustment assembly 20, a second adjustment assembly, and a tool mount 40.

Specifically, the boring tool rest is connected to the boring bar through a mounting assembly 10; the two ends of the first adjusting component are detachably connected with the mounting component 10 and the second adjusting component respectively, so that water pipes with different processing pipe diameters can be adapted by replacing the first adjusting component or/and the second adjusting component 30 with different lengths, and the first adjusting component is preferably replaced to adapt to the water pipes with different processing pipe diameters in consideration of the fact that the mounting requirement between the tool fixing component 40 and the second adjusting component is better than that of the second adjusting component 30 and the first adjusting component, and correspondingly, the tool fixing component 40 is more time-consuming and labor-consuming to mount on the second adjusting component.

The mounting assembly 10 comprises a first mounting part 11 and a second mounting part 12 which are fixedly connected into a whole, and the first mounting part 11 is detachably connected with the boring bar. The first adjustment assembly comprises a third mount 22, a first tube section 21 and a fourth mount 23; the third installation part 22 is fixedly connected to one end of the first pipe section 21 and detachably connected with the second installation part 12; the fourth mounting member 23 is fixedly connected to the other end of the first pipe section 21. The second adjustment assembly comprises a fifth mounting member 32 and a second pipe section 31, wherein the fifth mounting member 32 is fixedly connected to one end of the second pipe section 31 and detachably connected to the fourth mounting member 23. A cutter holder 40 is attached to the other end of the second tube section 31.

Specifically, the first and

second mounting members

11 and 12 may be integrally provided through a process such as welding. The first mounting member 11 is used as a separate component and mounted on the boring bar, so that the range of the load actually borne by the first mounting member 11 can be determined in conjunction with the parameters of the pipe diameter to be machined of the water pipe, the self weight of the boring cutter holder, and the like, thereby enhancing the rigidity, strength, and stability of the boring cutter holder in view of the design parameters of the first mounting member 11 itself without thickening the entire mounting plate 6050 as in the prior art.

The two ends of the first pipe section 21 can also be respectively connected with the third installation part 22 and the fourth installation part 23 through a welding process, and the first pipe sections 21 with different lengths can adapt to water pipes with different processing pipe diameters.

The two ends of the second pipe section 31 can also be respectively connected with the fifth mounting part 32 and the cutter fixing part 40 through a welding process, and the second pipe sections 31 with different lengths can adapt to water pipes with different processing pipe diameters.

With continued reference to fig. 2, in one embodiment, the second mounting element 12 and the third mounting element 22, and the fourth mounting element 23 and the fifth mounting element 32 are connected by fasteners 70 to facilitate assembly and disassembly.

With continued reference to fig. 2, in one embodiment, the second mounting element 12, the third mounting element 22, the fourth mounting element 23, and the fifth mounting element 32 are flanges, which are illustrated simply as square flanges in fig. 2, but in other embodiments, the shape of the flanges is not limited.

With continued reference to fig. 2, in one embodiment, tool holder 40 includes a tool holding portion 41, wherein tool holding portion 41 is a three-sided slot-shaped body and opens to the side. In other words, the tool fixing portion 41 is a through groove having three side walls, wherein the opening of the tool fixing portion 41 faces one side; further, one end of the tool fixing portion 41 is connected to the second pipe section 31, and the other end is connected to the outside.

Further, the cutter holder 40 further includes a sixth mounting member 42, and the cutter-fixing portion 41 is fixed to the second pipe section 31 by the sixth mounting member 42. In detail, the sixth mounting member 42 may have a plate-like structure, and the tool fixing portion 41 and the second pipe section 31 are respectively fixed to both sides of the sixth mounting member 42, which makes the installation area between the tool fixing portion 41 and the second pipe section 31 larger, thereby making the connection more stable. Of course, in other embodiments, it is within the scope of the present invention to directly fasten the tool-securing portion 41 to the second tube section 31.

With reference to fig. 2, in any of the above embodiments, the first mounting member 11 is an arc-shaped plate, and the curved surface of the first mounting member 11 contacts the boring bar surface. Specifically, the curved surface of the outer ring of the first mounting member 11 may be partially flattened and then fixed to the second mounting member 12, or may be welded directly to the second mounting member 12 without flattening, and the two members may be partially filled with a solder to reinforce the connection between the two members. In addition, the surface contact here can be understood as the direct contact between the first mounting part 11 and the boring bar; it is also understood that the two are in indirect contact, for example, a mounting structure is also provided on the boring bar for connecting the boring holder, with which mounting structure the curved surface of the inner ring of the first mounting part 11 is in direct contact.

With continued reference to fig. 2, in accordance with any of the above embodiments, the first mounting member 11 is connected to the boring bar by a fastener 70. In detail, the first mounting member 11 has mounting holes on both sides thereof, and boring bars are connected to the mounting holes.
