Abstract
Description
Technical Field
[0001] This utility model relates to the field of tool clamping technology, and in particular to a clamping set. Background Technology
[0002] With the continuous improvement of machining technology, the precision required for some products during machining also increases. Triangular cutting tools are commonly used for turning parts during this process. The cutting edge of a triangular cutting tool is typically an equilateral or isosceles triangle with three sharp angles. This unique cutting edge design gives triangular cutting tools not only excellent cutting performance but also high stability. However, during machining, a fixture matching the triangular cutting tool is needed to fix the tool in place, thereby ensuring stability and precision during the machining process. Most existing fixtures are quite complex, inconvenient to use, and unstable, leading to poor machining accuracy and reduced yield in turning operations.
[0003] Therefore, there is an urgent need for a fixture kit to solve the above-mentioned technical problems. Utility Model Content
[0004] The purpose of this utility model is to provide a clamping kit that is not only simple in structure but also has a good clamping effect on the cutting tool, which not only ensures the machining accuracy but also improves the convenience of operation.

[0008] The clamping member includes a first body and a second body coaxially connected. The first body can be installed into the mounting hole. The second body has a clamping groove at one end away from the first body. The clamping groove can clamp the non-cutting edge of the tool.
[0009] A locking sleeve is fitted onto the outer periphery of the second body and clamps the second body radially so that the clamping groove can clamp the cutting tool.
[0010] Preferably, the first body is provided with a limiting part, the diameter of which is larger than the diameter of the first body; one end of the triangular prism along the axial direction is provided with a groove communicating with the mounting hole, and the diameter of the groove is larger than the diameter of the mounting hole. When the first body is installed in the mounting hole, the limiting part can abut and limit itself in the groove.
[0011] Preferably, the groove is coaxially arranged with the mounting hole, and the limiting part is coaxially arranged with the first body.
[0012] Preferably, at least two locking holes are provided on one side of the triangular prism, and at least one of the locking holes is radially connected to the mounting hole and at least one of the locking holes is radially connected to the groove. The locking member can be installed in the locking hole so as to lock the first body in the mounting hole.
[0013] Preferably, at least one locking hole is provided on each of the remaining sides of the triangular prism, and at least one locking hole communicates with the mounting hole or the groove.
[0014] Preferably, the clamping groove is a cross groove, and the second body has two slots in the radial direction, the two slots intersecting in a cross shape and both connected to the cross groove.
[0015] Preferably, the end of the second body away from the first body is the clamping end, and the diameter of the clamping end gradually decreases in the direction away from the first body.
[0016] Preferably, the locking sleeve is threaded to the outer periphery of the second body, and one end of the locking sleeve is provided with a locking part. When the locking sleeve is screwed on, the locking part can press the clamping end radially inward so that the tool is clamped in the clamping groove.

The clamping element includes a first body and a second body that are coaxially connected. The first body can be installed into the mounting hole. The second body has a clamping groove at the end away from the first body. The clamping groove can clamp the non-cutting edge of the tool. The locking sleeve can be fitted onto the outer periphery of the second body and clamp the second body radially so that the clamping groove can clamp the tool.
[0021] In this structure, the triangular prism not only ensures the structural stability of the clamping component, but also allows the operator to easily confirm the cutting edge direction of the tool through the triangular face of the prism, further improving operational convenience. Furthermore, the non-cutting edge of the tool can be directly installed into the clamping slot, making operation simple and convenient.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0035] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0036] This embodiment provides a clamping kit, such as Figures 1-5 As shown, the clamping kit includes a triangular prism 10, a clamping member 20, and a locking sleeve 30. The triangular prism 10 has a mounting hole 11 along its own axial direction. The clamping member 20 includes a first body 21 and a second body 22 coaxially connected. The first body 21 can be installed into the mounting hole 11. The second body 22 has a clamping groove 221 at one end away from the first body 21. The clamping groove 221 can clamp the non-cutting edge of the tool. The locking sleeve 30 can be sleeved on the outer periphery of the second body 22 and clamp the second body 22 radially so that the clamping groove 221 can clamp the tool.
[0037] In this structure, the triangular prism 10 not only ensures the structural stability of the clamping member 20, but also allows the operator to easily confirm the cutting edge direction of the tool through the triangular face of the prism 10, further improving operational convenience. Furthermore, the non-cutting edge of the tool can be directly installed into the clamping groove 221, making operation simple and convenient. Finally, the locking sleeve 30 radially locks the second body 22 of the clamping member 20, causing the second body 22 to deform radially inward, thus allowing the clamping groove 221 to clamp the tool. The overall structure is simple, with high operability and flexibility.
[0038] Specifically, such as Figures 2-4As shown, a limiting part 211 is provided on the first main body 21, and the diameter of the limiting part 211 is larger than the diameter of the first main body 21. A groove communicating with the mounting hole 11 is provided at one end of the triangular prism 10 along the axial direction, and the diameter of the groove is larger than the diameter of the mounting hole 11. When the first main body 21 is installed in the mounting hole 11, the limiting part 211 can abut and limit its position within the groove. Through the interaction between the limiting part 211 and the groove, the clamping member 20 can be axially limited, preventing the clamping member 20 from moving axially into the mounting hole 11 during the turning process, thereby ensuring the stability of the structure.
[0039] In addition, such as Figures 2-4 As shown, the groove and the mounting hole 11 are coaxially arranged, and the limiting part 211 is coaxially arranged with the first body 21. This structure not only facilitates the installation and fixation of the clamping member 20, but also, through the coaxial arrangement, can further improve the stability of the clamping member 20, thereby improving the stability of tool clamping.
[0040] To further simplify the overall structure, such as Figures 1-2 As shown, at least two locking holes 12 are provided on one side of the triangular prism 10, and at least one locking hole 12 is radially connected to the mounting hole 11, and at least one locking hole 12 is radially connected to the groove. The locking member 40 can be installed in the locking hole 12 to lock the first body 21 in the mounting hole 11. This arrangement is not only simple but also convenient to operate. Simply installing the locking member 40 in the locking hole 12 is enough to achieve the limiting effect on the clamping member 20. In addition, multiple locking holes 12 can significantly increase the locking effect, and since both the mounting hole 11 and the groove are connected to the locking holes 12, at least one locking member 40 is pressed against the first body 21, and at least one locking member 40 is pressed against the limiting part 211, thereby significantly improving the uniformity of force on the clamping member 20 and ensuring the stability of the structure.
[0041] It should be noted that in this embodiment, two locking holes 12 are provided on one side of the triangular prism 10, and one locking hole 12 is connected to the mounting hole 11, and the other locking hole 12 is connected to the groove. The locking hole 12 is a threaded hole, and the locking part 40 used with it is an internal hexagonal round-end locking screw. When the screw is screwed into the threaded hole, its other end can press against the first body 21 or the limiting part 211, thereby preventing the clamping part 20 from shaking. In addition, the specific model of the screw is (M3X6, the male diameter is 3 mm, and the screw length is 6 mm). The threaded engagement has a good locking effect. At the same time, this kind of screw has the characteristics of easy assembly, anti-loosening, and high reliability.
[0042] In addition, such as Figure 1 and Figure 2As shown, at least one locking hole 12 is provided on each of the other sides of the triangular prism 10, and at least one locking hole 12 communicates with the mounting hole 11 or the groove. This arrangement allows the locking member 40 to be installed on each of the other sides, thereby further improving the fixing effect on the clamping member 20.
[0043] It should be noted that in this embodiment, each of the remaining sides is provided with a locking hole 12, and each locking hole 12 is located at the center of the side, which not only improves the symmetry of force distribution but also enhances the aesthetics of the overall structure. In other embodiments, the position of the locking holes 12 can be adjusted according to actual needs; this embodiment does not impose specific limitations.
[0044] In addition, such as Figures 1-4 As shown, the clamping groove 221 is a cross groove, and the second body 22 has two slots 222 radially intersecting and connecting to the cross groove. First, the cross groove facilitates the installation of tools, ensuring ease of operation. Second, the two slots 222 are connected to the other end of the clamping groove 221, so when the locking sleeve 30 is fitted around the outer periphery of the second body 22, the second body 22 can quickly deform radially inward, thereby improving the locking effect and enhancing the user experience.
[0045] It should be noted that the center of the cross groove is on the axis of the clamping member 20, and the intersection of the two slots 222 is also on the axis of the clamping member 20. This ensures that the force point is always on the axis of the clamping member 20 when clamping the tool, thus solving the problem of wobbling caused by the misalignment of the clamping member 20 and the tool, and thus greatly improving the stability of the structure.
[0046] Furthermore, such as Figures 1-4 As shown, the end of the second body 22 that is away from the first body 21 is the clamping end, and the diameter of the clamping end gradually decreases in the direction away from the first body 21. This arrangement ensures that the clamping end can quickly deform and move towards the center after being subjected to radial preload, thereby quickly clamping the tool and improving the user experience and operational flexibility.
[0047] Correspondingly, such as Figure 1 , Figure 2 and Figure 5As shown, the locking sleeve 30 is threadedly engaged with the outer circumference of the second body 22, and one end of the locking sleeve 30 is provided with a locking part 31. When the locking sleeve 30 is screwed, the locking part 31 can press the clamping end radially inward, so that the tool is clamped in the clamping groove 221. In this structure, the locking sleeve 30 is threadedly engaged with the second body 22, so the position of the locking sleeve 30 can be adjusted by screwing, thereby achieving a pre-tightening effect; when the locking sleeve 30 moves axially towards the first body 21, the locking part 31 can fully press the clamping end, thereby ensuring that the clamping end can clamp the tool in the clamping groove 221. The structure is simple and easy to operate, which greatly improves the clamping efficiency and clamping stability.
[0048] In addition, such as Figure 1 As shown, the radial cross-section of the triangular prism 10 is an equilateral triangle. This design makes the overall structure more stable, ensuring that the tool will not wobble during operation, thereby guaranteeing a high yield rate.
[0049] Correspondingly, such as Figure 1 As shown, the corners of the triangular prism 10 are provided with rounded chamfers 13. The rounded chamfers 13 not only reduce wear on parts, but also prevent scratches to operators, thus improving both the service life of the parts and the safety of operation.
[0050] Furthermore, it should be noted that in this embodiment, both the clamping member 20 and the locking sleeve 30 are made of 40Cr (alloy structural steel), with a carbon content of 0.40% and a chromium content between 0.80% and 1.10%. It features high strength, high hardness, good wear resistance, and high fatigue strength.
[0051] In summary, the fixture kit in this embodiment is not only simple in structure, but also has a good clamping effect on the cutting tool and high stability. It not only ensures machining accuracy, but also greatly improves the convenience of operation.
[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
