Description

Technical Field

[0001] The utility model relates to the technical field of composite cutting tools, in particular to a composite cutting tool with a replaceable cutting head. Background Art

[0002] A tool is a tool used for cutting processing in mechanical manufacturing, also known as a cutting tool; a compound tool is a special tool that combines two or more similar or different hole processing tools into one. It can complete multiple processes such as drilling, reaming, reaming, countersinking and boring in one processing process, and has the characteristics of high efficiency, high precision and high reliability in forming processing.

[0003] Please refer to patent announcement number CN215145337U for a composite tool that is easy to replace. The patent states that "composite tools in the prior art require that two tools be replaced simultaneously after being worn out, and cannot be replaced separately. When only one tool is worn out, replacing the two tools wastes materials." This patent further facilitates the disassembly of the disc tool and the spherical tool by providing a connecting block on the mounting handle, connecting the disc tool and the connecting block through a first disassembly component, and connecting the disc tool and the spherical tool through a second disassembly component, thereby facilitating the separate replacement of the disc tool and the spherical tool, saving materials, and improving the utilization rate of the tools.

[0004] However, although the above patent can replace the disc cutter and the spherical cutter separately, when replacing the disc cutter, it is necessary to remove the spherical cutter before removing the disc cutter. Similarly, when installing the cutter, the spherical cutter must be installed after the disc cutter is installed. The operation process of replacing the disc cutter separately is relatively cumbersome, not convenient to use, and the use effect is poor. In view of this, the present application proposes a composite cutter with a replaceable cutter head. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a composite tool with replaceable tool heads, which is capable of independently replacing a disc tool and a spherical tool, and allows the disassembly and assembly of the two different tools without interference, so that the disassembly and assembly and replacement of a single tool is more convenient, and the practicality of the device is effectively improved. It solves the problem in the prior art that the two tools need to be replaced simultaneously after being worn out during use, and cannot be replaced individually. When only one of the tools is worn out, replacing the two tools results in a waste of materials.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a composite tool with a replaceable cutter head, comprising a mounting handle, a spherical tool, a disc tool, a spherical tool mounting structure installed inside the mounting handle and used to install and fix the spherical tool, and a disc tool mounting structure installed inside the mounting handle and used to install and fix the disc tool;

[0010] By adopting the above technical solution, it is convenient to extend the lower half of the mounting handle into the spherical tool by means of the positioning groove, so as to keep the spherical tool accurately positioned on the mounting handle.

[0011] Optionally, an insertion opening corresponding to the position of the limiting block is provided on the top of the insert block, a limiting rotation groove slidably matched with the limiting block is provided inside the insert block, and the limiting rotation groove is communicated with the insertion opening.

[0012] By adopting the above technical solution, it is convenient to extend the limit block into the insert block by using the insertion opening, and to rotate the limit block in the insert block by using the limit rotation groove, so as to utilize the mutual interference between the limit block and the insert block to maintain the installation stability of the limit block and the insert block.

[0013] Optionally, a movable slider hinged to a connecting rod is fixedly connected to a side of the threaded block away from the axis of the mounting handle, and a displacement groove slidably matched with the movable slider is provided on the outer side of the mounting handle.

[0014] By adopting the above technical solution, the movable slider can be easily moved in the mounting handle by utilizing the shifting groove, so as to maintain the stability of the movable slider, thereby limiting the rotation of the threaded block.

[0015] Optionally, the transmission adjustment assembly includes a transmission gear fixedly connected to the top of the threaded rod, a rotating gear ring slidably connected to the inside of the mounting handle and meshing with the transmission gear, an operating rod fixedly connected to the top of the rotating gear ring and slidably adapted to the mounting handle, and a limiting structure installed on the top of the mounting handle and used to limit the movement of the operating rod and the rotating wheel.

[0016] By adopting the above technical solution, it is convenient for the rotating gear ring to drive the threaded rod to rotate by utilizing the transmission effect with the transmission gear, thereby realizing synchronous rotation of the threaded rod in three directions.

[0017] Optionally, a plurality of limiting sliding blocks are fixedly connected to the outer side of the rotating gear ring, and a limiting sliding groove slidably matched with the limiting sliding block is provided inside the mounting handle.

[0018] By adopting the above technical solution, it is convenient to make the limiting slide block move in the installation handle by using the limiting slide groove, so as to realize the positioning installation of the rotating gear ring and maintain the stable movement of the rotating gear ring.

[0019] Optionally, the limiting structure includes a limiting cover movably connected to the top of the mounting handle, a limiting wheel groove opened at the bottom of the limiting cover and slidably matched with the rotating wheel, and a limiting rod groove opened at the bottom of the limiting cover and slidably matched with the operating rod.

[0022] By adopting the above technical solution, it is convenient to use the positioning rod inserted into the installation handle to limit the rotation of the limiting cover itself, so as to maintain the limiting effect on the operating rod and the rotating wheel.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The composite tool with replaceable cutter head realizes the installation of spherical tools and disc tools through two different installation methods, so that after the tools are worn, the disc tools and spherical tools can be replaced separately to avoid material waste caused by replacing the two tools; because the two installation methods are independently designed, there is no mutual interference in the disassembly and assembly process of the disc tools and the spherical tools, which can facilitate the staff to disassemble and assemble a certain tool separately, so as to make the disassembly, assembly and replacement operation of a single tool more convenient and make it more convenient to use, thereby effectively enhancing the practicality of the composite tool and improving the utilization rate of the tool.

[0031] See also Figure 1-4 In this embodiment, a composite tool with a replaceable cutter head includes a mounting handle 1, a spherical tool 5, a disc tool 7, a ball tool mounting structure installed inside the mounting handle 1 and used to install and fix the spherical tool 5, and a disc tool mounting structure installed inside the mounting handle 1 and used to install and fix the disc tool 7.

[0032] In this embodiment, the ball cutter mounting structure includes an insert block 6 fixedly connected to the top of the spherical cutter 5 and extending to the inside of the mounting handle 1, a rotating shaft 2 rotatably connected to the inside of the mounting handle 1, a limit block 3 fixedly connected to the bottom of the rotating shaft 2 and slidably adapted to the insert block 6, and a rotating wheel 4 fixedly connected to the top of the rotating shaft 2; the movement of the insert block 6 is conveniently restricted by the limit block 3, so that the spherical cutter 5 can be installed on the mounting handle 1.

[0033] Among them, the mounting handle 1 is a T-shaped structure, and the top of the spherical tool 5 is provided with a positioning groove 501 that is slidably adapted to the lower half of the mounting handle 1, so that the mounting handle 1 can extend into the spherical tool 5 using the positioning groove 501, so as to ensure the accurate positioning of the spherical tool 5 on the mounting handle 1.

[0034] Among them, an insertion port 601 corresponding to the position of the limit block 3 is opened on the top of the insertion block 6, and a limit rotation groove 602 slidably adapted to the limit block 3 is opened inside the insertion block 6, and the limit rotation groove 602 is connected with the insertion port 601, so that the limit block 3 can be placed in the insertion block 6 through the insertion port 601, and the limit block 3 can be rotated in the limit rotation groove 602 in the insertion block 6, so as to make the limit block 3 staggered from the insertion port 601, and then utilize the resistance of the insertion block 6 to the limit block 3 to limit the movement of the insertion block 6 and the spherical tool 5.

[0035] In this embodiment, the disc cutter mounting structure includes a limit block 103 fixedly connected to the outside of the mounting handle 1 and clamping the disc cutter 7, three rotating stops 12 rotatably connected to the inside of the mounting handle 1, a threaded rod 8 rotatably connected to the inside of the mounting handle 1 and corresponding to the position of the rotating stops 12, a threaded block 9 threadedly connected to the outside of the threaded rod 8, a connecting rod 11 rotatably connected to the end of the rotating stop 12 and hinged to the threaded block 9, and a transmission adjustment component installed inside the mounting handle 1 and used to link each threaded rod 8.

[0036] Among them, a movable slider 10 hinged to a connecting rod 11 is fixedly connected to one side of the threaded block 9 away from the axis of the mounting handle 1, and a shifting groove 101 slidably adapted to the movable slider 10 is provided on the outer side of the mounting handle 1, so as to conveniently utilize the movement of the movable slider 10 in the shifting groove 101 to limit the rotation of the threaded block 9, so as to maintain the activity stability of the threaded block 9.

[0037] In this embodiment, the transmission adjustment assembly includes a transmission gear 13 fixedly connected to the top of the threaded rod 8, a rotating gear ring 14 slidably connected to the inside of the mounting handle 1 and meshing with the transmission gear 13, an operating rod 15 fixedly connected to the top of the rotating gear ring 14 and slidably adapted to the mounting handle 1, and a limiting structure installed on the top of the mounting handle 1 and used to limit the movement of the operating rod 15 and the rotating wheel 4. It is convenient to make the transmission gear 13 rotate with the rotation of the rotating gear ring 14, so as to drive the threaded rod 8 to rotate.

[0038] Among them, a plurality of limiting sliders 1401 are fixedly connected to the outer side of the rotating gear ring 14, and a limiting groove 102 slidably adapted to the limiting slider 1401 is opened inside the mounting handle 1, so as to conveniently utilize the movement of the limiting slider 1401 in the limiting groove 102 to maintain the stability of the movement of the rotating gear ring 14.

[0039] In this embodiment, the limiting structure includes a limiting cover 16 movably connected to the top of the mounting handle 1, a limiting wheel groove 1603 opened at the bottom of the limiting cover 16 and slidably matched with the rotating wheel 4, and a limiting rod groove 1602 opened at the bottom of the limiting cover 16 and slidably matched with the operating rod 15; it is convenient for the limiting cover 16 to clamp the rotating wheel 4 using the limiting wheel groove 1603, and to clamp the operating rod 15 using the limiting rod groove 1602, so as to limit the movement of the rotating wheel 4 and the operating rod 15 when the limiting cover 16 does not rotate.

[0040] Among them, the bottom of the limit cover 16 is fixedly connected with a positioning rod 1601 extending into the inside of the installation handle 1. There are multiple positioning rods 1601, and the positioning rods 1601 are evenly arranged in a circular shape, which makes it convenient to use the positioning rods 1601 inserted into the installation handle 1 to limit the rotation of the limit cover 16.

[0041] The working principle of the above embodiment is:

[0042] When installing the spherical cutter 5, the lower half of the installation handle 1 needs to be extended into the spherical cutter 5 by using the positioning groove 501, and the limit block 3 needs to be extended into the insert block 6 through the insertion opening 601. Then, the limit block 3 is rotated in the limit rotation groove 602 by rotating the rotating wheel 4, so that the limit block 3 is staggered from the insertion opening 601, so that the insertion block 6 can resist the limit block 3, thereby limiting the movement of the insert block 6 and the spherical cutter 5, so that the spherical cutter 5 can be installed on the installation handle 1.

[0043] When installing the disc cutter 7, it is first necessary to sleeve the disc cutter 7 on the installation handle 1, and make the limit clamping block 103 clamp the disc cutter 7 to limit its rotation, and then drive the rotating gear ring 14 to rotate through the operating rod 15, and make the rotating gear ring 14 drive the threaded rod 8 to rotate by the transmission effect with the transmission gear 13, so that the threaded block 9 can drive the top of the connecting rod 11 to move with the rotation of the threaded rod 8 by the moving slider 10, so as to achieve the effect of adjusting the rotation angle of the rotating block 12. When the rotating block 12 tends to be horizontal, the rotating block 12 can fit the top surface of the disc cutter 7, so as to limit the movement of the disc cutter 7, thereby realizing the installation and fixation of the disc cutter 7;

[0044] This makes it easy to replace the disc cutter 7 and the spherical cutter 5 separately after the cutter is worn, and allows the staff to disassemble and assemble a certain cutter separately, making it more convenient to use, effectively enhancing the practicality of the composite cutter and improving the utilization rate of the cutter.
