[0029] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0030] Please combine Figures 1 to 2 This utility model provides a chip-cutting fixture 100 and a chip-cutting device, which can be used to process threaded holes. It is applicable to processing holes of different diameters, making its use more flexible. It also allows for the installation and removal of the sleeve 150, offering a wide range of functions.
[0031] The chip-cutting fixture 100 includes a chip-cutting column 110, a sleeve 150, and a mounting end 151. One end of the chip-cutting column 110 has a first chip-cutting portion 120, and the other end has a second chip-cutting portion 130; the chip sizes of the first chip-cutting portion 120 and the second chip-cutting portion 130 are different. The sleeve 150 is detachably connected to the chip-cutting column 110 and is fitted onto either the first chip-cutting portion 120 or the second chip-cutting portion 130. The mounting end 151 is located on the sleeve 150 and is used to connect to the part to be disassembled or to a driving component. This chip-cutting fixture 100 can achieve chip cutting of different hole diameters and also has a sleeve 150 disassembly function, making it flexible in application scenarios and convenient to use.
[0032] The first cutting section 120 is provided with a first cutting edge 121 and a first chip removal groove 122, which are spaced apart in the circumferential direction. The first cutting edge 121 is used to cut the workpiece to cut out the required shape on the workpiece.
[0033] In this embodiment, multiple sets of first cutting edges 121 are provided, and these sets of first cutting edges 121 are spaced apart circumferentially. Each set of first cutting edges 121 includes multiple cutting portions spaced apart axially along the chip column 110, and the cutting portions are arc-shaped. In this way, when multiple sets of first cutting edges 121 work together to machine threads on the inner wall of the hole, thereby achieving the machining of threaded holes.
[0034] The second cutting section 130 is provided with a second cutting edge 131. The structure and shape of the second cutting edge 131 are similar to those of the first cutting edge 121. The chip sizes of the first cutting edge 121 and the second cutting edge 131 are different. It can be understood that the radius of the arc of the cutting portion in the first cutting edge 121 is different from the radius of the arc in the second cutting edge 131. Thus, the first cutting edge 121 and the second cutting edge 131 can process threaded holes of different diameters. For example, if you want to tap a hole with a smaller diameter to form a threaded hole, you can choose to process the hole with the first cutting edge 121. If you want to tap a hole with a larger diameter to form a threaded hole, you can choose to process the hole with the second cutting edge 131. This is convenient to operate, and the same fixture can be used to process different hole diameters, making it more adaptable and flexible in application scenarios.
[0035] The first chip-removing section 120 is provided with a plurality of first chip-removing grooves 122, each first chip-removing groove 122 being arranged along the axial direction of the chip column 110. The plurality of first chip-removing grooves 122 are spaced apart circumferentially along the chip column 110. In this embodiment, there are four sets of first cutting edges 121 and four first chip-removing grooves 122, meaning that one first chip-removing groove 122 is provided between two adjacent first cutting edges 121. The first chip-removing grooves 122 can promptly discharge chips falling during tapping, preventing chips from clogging the channel and improving cutting accuracy and efficiency. It is easy to understand that the first chip-removing grooves 122 can promptly discharge chips, reduce wear on the first cutting edges 121 and chips, reduce the cutting resistance of the first cutting edges 121, prevent the first cutting edges 121 from breaking, and help extend the service life of the first cutting edges 121.
[0036] Correspondingly, the second chip removal section 130 is provided with a second chip removal groove 132, and the second cutting edge 131 and the second chip removal groove 132 are arranged at intervals in the circumferential direction. There are four second chip removal grooves 132 and four sets of second cutting edges 131, with one second chip removal groove 132 between two adjacent second cutting edges 131. The second chip removal groove 132 can promptly remove chips that fall off during tapping, prevent chips from clogging the channel, and improve chip cutting accuracy and efficiency. It also reduces the wear of the second cutting edge 131 and chips, reduces the cutting resistance of the second cutting edge 131, prevents the second cutting edge 131 from breaking, and helps extend the service life of the second cutting edge 131.
[0037] Of course, in other embodiments, the number and shape of the first cutting edge 121, the number and shape of the second cutting edge 131, the number and shape of the first chip removal groove 122, the number and shape of the second chip removal groove 132, etc. can be flexibly set according to the actual situation, and no specific limitation is made here.
[0038] Optionally, the first chip removal groove 122 and the second chip removal groove 132 are correspondingly arranged. This arrangement facilitates the discharge of chips and results in more even force distribution. Of course, in some other embodiments, the first chip removal groove 122 and the second chip removal groove 132 can also be staggered, which is not specifically limited here.
[0039] Optionally, the chip cylinder 110 is provided with a mounting portion, which is connected to the sleeve 150 and located between the first chip portion 120 and the second chip portion 130. The sleeve 150 and the chip cylinder 110 are detachably connected via the mounting portion. When connected, the sleeve 150 and the chip cylinder 110 can protect either the first chip portion 120 or the second chip portion 130. When detached, the sleeve 150 can be used as a separate assembly / disassembly tool.
[0040] Optionally, the chip fixture 100 also includes a fastener 140. The fastener 140 includes, but is not limited to, bolts. The mounting portion uses a first threaded hole 111. The sleeve 150 is provided with a second threaded hole 152 corresponding to the first threaded hole 111. The fastener 140 passes through the second threaded hole 152 and the first threaded hole 111 in sequence to connect the sleeve 150 and the chip cylinder 110.
[0041] It should be noted that the length of the sleeve 150 is less than the length of the chip column 110. The sleeve 150 can be fitted onto one end of the first chip portion 120 or one end of the second chip portion 130. Since the mounting portion on the chip column 110 is located in the middle, that is, between the first chip portion 120 and the second chip portion 130, the sleeve 150 can be connected to the chip column 110 through the mounting portion regardless of which end of the chip column 110 it is fitted onto.
[0042] It is understood that when the sleeve 150 is fitted onto the first cutting section 120, it can protect the first cutting edge 121 of the first cutting section 120. In this state, the second cutting section 130 can be used for tapping operations, and the sleeve 150 will not affect or interfere with the operation of the second cutting section 130. When the sleeve 150 is fitted onto the second cutting section 130, it can protect the second cutting edge 131 of the second cutting section 130. In this state, the first cutting section 120 can be used for tapping operations, and the sleeve 150 will not affect or interfere with the operation of the first cutting section 120.
[0043] In other embodiments, the sleeve 150 and the chip cylinder 110 may also be connected by other methods, such as threaded connection, snap-fit or magnetic bonding, etc., which are not specifically limited here.
[0044] Optionally, the mounting end 151 is a hollow structure, and its cross-section is triangular, quadrilateral, pentagonal, hexagonal, or octagonal. When the chip cylinder 110 needs to be tapped, the mounting end 151 is used to connect with the driving component, transmitting power from the driving component to the chip cylinder 110 to complete the tapping operation. After the sleeve 150 and the chip cylinder 110 are disassembled, the sleeve 150 serves as a separate assembly / disassembly tool, and the mounting end 151 is used to connect with the part to be assembled / disassembled, such as a nut. By fitting the mounting end 151 onto the nut and rotating the sleeve 150 with a wrench or other disassembly tool, the nut can be tightened or loosened, thus achieving the assembly / disassembly function. Optionally, the mounting end 151 has a square or hexagonal cross-section, which can be used as an internal square or internal hex wrench to achieve the assembly / disassembly function.
[0045] This chip-cutting fixture 100, with its first chip-cutting section 120 and second chip-cutting section 130 of different sizes, can meet tapping requirements of different diameters, is easy to use, and has flexible application scenarios. Furthermore, its compact structure reduces the number of parts required for tapping operations, making it easy to carry and pick up. In addition, the included sleeve 150 not only protects the chip-cutting section but can also be used independently as a disassembly tool, offering multiple functions.
[0046] This utility model embodiment also provides a chip cutting device, including a drive component and a chip cutting fixture 100 as described in any of the foregoing embodiments. The drive component is connected to a mounting end 151. The drive component includes, but is not limited to, a motor, which can electrically drive the first chip cutting section 120 or the second chip cutting section 130 to perform tapping operations, resulting in high operating efficiency and convenient operation.
[0047] In summary, the chip-cutting fixture 100 and chip-cutting device provided by this utility model embodiment have the following beneficial effects:
[0048] The chip-cutting fixture 100 provided in this embodiment of the invention, due to having a first chip-cutting section 120 and a second chip-cutting section 130 of different sizes, can meet the tapping requirements of different diameter sizes, is easy to use, and has flexible application scenarios. Its compact structure reduces the number of parts required for tapping operations. Furthermore, since the chip column 110 is equipped with a sleeve 150, the sleeve 150 can not only protect the first chip-cutting section 120 or the second chip-cutting section 130, but also be used independently as a disassembly tool, offering rich functionality and ease of use.
[0049] The chip-cutting device provided in this embodiment includes the aforementioned chip-cutting fixture 100, which has a compact structure and rich functions. It can be used as a chip-cutting fixture 100, suitable for tapping operations of different hole diameters, and can also be used as an assembly / disassembly tool to realize the assembly / disassembly function of the sleeve 150.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
