Description

Technical Field

[0001] This utility model belongs to the technical field of turning devices, and in particular relates to a turning tool with multiple mounting angles. Background Technology

[0002] Turning is one of the most basic and widely used cutting processes in machining. It mainly achieves the machining of the workpiece's outer circle, end face, thread, groove, and other surfaces by rotating the workpiece and moving the turning tool in a direction parallel or perpendicular to the workpiece's rotation axis. The working angle of the turning tool's cutting edge directly determines the cutting force distribution, surface quality, and tool life, and is a key parameter affecting the machining effect.

[0003] Most existing turning tools have a fixed single-angle cutting edge design. If the angle needs to be adjusted to adapt to different machining requirements (such as a large principal cutting edge angle for roughing to resist impact and a small principal cutting edge angle for finishing to maintain surface finish), it usually relies on the rotation of the lathe tool holder. In non-high-end lathes (such as ordinary horizontal lathes), the tool holder angle adjustment lacks a precise positioning reference and mostly relies on manual rotation by the operator, resulting in poor accuracy. To improve the accuracy of the tool holder angle adjustment, it is necessary to add precision components such as a dial and a locking positioning mechanism, which increases the cost of lathe modification. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a multi-angle turning tool that can adapt to the turning angles of various turning tools, avoids reliance on the rotation adjustment of the lathe seat, and is cost-effective.

[0005] In view of this, the present invention provides a turning tool with multiple mounting angles, comprising: The cutting head has a turning edge at the end; The tool holder has a mounting slot for mounting the tool head; A locking element, mounted on the tool holder, is used to limit and lock the tool head in the vertical direction after installation; The mounting slot includes multiple slots, which are used to limit the horizontal position of the cutter head end when the cutter head is installed at different angles.

[0006] In the above technical solution, further: Turning cutting edges include roughing cutting edges located at both ends of the cutting head and used for rough turning, and finishing cutting edges used for finish turning.

[0007] In the above technical solution, further: A clearance groove is formed on the side of the slot away from the cutter head, which is used to prevent the cutting edge from making hard contact with the inner wall of the slot after the end of the cutter head is inserted into the slot.

[0008] In the above technical solution, further: The locking component includes a locking bolt, which passes through the cutter head and is threadedly connected to the cutter holder; The cutter head has a first through hole in the middle that is compatible with the locking bolt, and multiple slots are arranged circumferentially around the axis of the first through hole.

[0009] In the above technical solution, further: The locking component also includes a connecting plate, one end of which has a second through hole through which the locking bolt passes, and the other end is engaged with the tool holder.

[0010] In the above technical solution, further: The tool holder has a socket, and the connecting plate has a pin that matches the socket; There are two insertion holes and two insertion posts, which together form a triangular structure with the second through hole.

[0011] In the above technical solution, further: The end of the insert away from the connecting plate is hemispherical.

[0012] In the above technical solution, further: The tool holder has a countersunk hole on the bottom wall of the mounting slot, and the countersunk hole is coaxial with the first through hole. A spring is installed in the countersunk hole and is sleeved on the locking bolt.

[0013] The beneficial effects of this utility model are as follows: 1. By creating mounting slots on the tool post for installing the tool head, and these mounting slots include multiple slots, the tool head can be quickly installed at different working angles by switching slots, based on the angle requirements of roughing and finishing machining scenarios, through pre-testing and pre-setting precise positions. This eliminates the need for rotation adjustment of the lathe tool holder, avoiding the angle errors caused by manual adjustment based on experience, effectively ensuring the consistency of the working angle of the turning edge, thereby improving the dimensional accuracy and surface quality of the workpiece. Furthermore, multiple angle functions can be achieved simply by machining multiple pre-set slots on the tool post, without requiring complex modifications to the lathe's base, resulting in low modification costs.

[0014] 2. By forming a roughing edge and a finishing edge at both ends of a cutting head, a single cutting head can perform both roughing and finishing functions, further reducing the cost of using turning tools. Furthermore, by creating a clearance groove, after the groove is embedded at the end of the cutting head, the clearance groove provides an independent space for the turning edge at the end of the cutting head, which can prevent hard friction or impact between the turning edge and the inner wall of the groove due to vibration during the cutting process, significantly extending the service life of the turning edge. 3. The connecting plate effectively improves the structural stability of the tool head installation. The three-point support formed by the triangular structure on the connecting plate further enhances the structural strength, preventing the locking bolts from tilting during use and improving the turning accuracy and stability.

[0016] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0017] Example 1: This embodiment provides a turning tool with multiple mounting angles, including: Cutting head 1, with a turning edge 2 formed at the end; The tool holder 3 has a mounting slot 4 for mounting the tool head 1; Locking element 5 is installed on the tool holder 3 and is used to limit and lock the tool head 1 in the vertical direction after installation; The mounting groove 4 includes multiple slots 40, and the slots 40 are used to limit the end of the cutter head 1 in the horizontal direction when the cutter head 1 is installed at different angles.

[0018] As can be seen from this embodiment, by opening a mounting slot 4 for mounting the tool head 1 on the tool holder 3, and the mounting slot 4 includes multiple slots 40, the tool head 1 can be quickly installed at different working angles by switching slots 40 according to the angle requirements of roughing and finishing machining scenarios and by pre-setting precise positions through trial testing; it does not rely on the rotation adjustment of the lathe tool holder, avoids the angle error of manual adjustment based on experience, effectively ensures the consistency of the working angle of the turning edge 2, and thus improves the dimensional accuracy and surface quality of the workpiece; Multi-angle functions can be achieved simply by machining multiple preset slots 40 on the tool holder 3, without the need for complex modifications to the lathe seat, resulting in low modification costs. Furthermore, by limiting and locking the cutter head 1 in the vertical direction with the locking member 5 and limiting the slot 40 in the horizontal direction, the installation stability of the cutter head 1 on the tool holder 3 can be effectively improved, ensuring turning accuracy.

[0019] Example 2: This embodiment provides a turning tool with multiple mounting angles, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The turning cutting edge 2 includes a roughing cutting edge located at both ends of the cutting head 1 and a finishing cutting edge used for rough turning, respectively.

[0020] As can be seen from this embodiment, by forming a roughing edge and a finishing edge at both ends of a cutting head 1, a single cutting head 1 can perform both roughing and finishing functions. Compared with using two cutting heads 1 (such as a cutting head 1 for roughing and a cutting head 1 for finishing), this further reduces the cost of using the turning tool. Moreover, it is only necessary to remove the locking member 5, reverse the direction of the cutting head 1, and install it in the corresponding slot 40, which is highly convenient.

[0021] Example 3: This embodiment provides a turning tool with multiple mounting angles, which, in addition to the technical solutions of the above embodiments, also has the following technical features: A clearance groove 41 is formed on the side of the slot 40 away from the cutter head 1, which is used to prevent the turning edge 2 from making hard contact with the inner wall of the slot 40 after the end of the cutter head 1 is inserted into the slot 40.

[0022] As can be seen from this embodiment, by opening the relief groove 41, after the slot 40 is embedded in the end of the cutter head 1, the relief groove 41 reserves an independent space for the turning edge 2 at the end of the cutter head 1, which can avoid hard friction or impact between the turning edge 2 and the inner wall of the slot 40 due to vibration during the cutting process, and significantly extend the service life of the turning edge 2. Furthermore, the clearance groove 41 can be formed simultaneously with the slot 40 during machining, without the need for additional complex tooling, resulting in high machining efficiency and low manufacturing cost; and the drilling depth and diameter can be flexibly adjusted according to the size of the turning blade 2 to adapt to different types of turning blade 2 designs.

[0023] Example 4: This embodiment provides a turning tool with multiple mounting angles, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The locking component 5 includes a locking bolt 50, and the locking bolt 50 passes through the cutter head 1 and is threadedly connected to the cutter holder 3; The cutter head 1 has a first through hole 10 in the middle that is adapted to the locking bolt 50, and multiple slots 40 are arranged at intervals in the circumferential direction around the axis of the first through hole 10.

[0024] As can be seen in this embodiment, the locking bolt 50 applies a vertical preload to the cutter head 1 through the first through hole 10, pressing the cutter head 1 tightly onto the tool holder 3; at the same time, the slot 40 restricts the rotational freedom of the cutter head 1 around the bolt axis through a rigid limit in the horizontal direction; the two work together to form a three-dimensional constraint of vertical locking and horizontal limiting, which, compared with multiple bolt fixation, can reduce the slight tilting of the cutter head 1 caused by uneven bolt force, ensure the stability of the working angle of the turning edge 2, and guarantee the turning machining accuracy; Multiple slots 40 are arranged circumferentially around the axis of the first through hole 10, which can quickly align different slots 40 without repeated disassembly and calibration, thus improving convenience; and the spacing between multiple slots 40 can be flexibly designed according to processing requirements, which can adapt to the angle parameters of different scenarios such as rough turning and finish turning.

[0025] Example 5: This embodiment provides a turning tool with multiple mounting angles, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The locking component 5 also includes a connecting plate 51, and one end of the connecting plate 51 has a second through hole 52 through which the locking bolt 50 passes, and the other end is engaged with the tool holder 3.

[0026] As can be seen from this embodiment, during turning, the cutting head 1 bears the cutting force in the horizontal direction (feed direction) as it moves with the feed motion; the connecting plate 51 directly bears part of the horizontal force through the snap-fit ​​structure with the tool holder 3 and transmits it to the tool holder 3 body, so that the locking bolt 50 mainly bears the vertical preload force, rather than the bending moment; compared with the structure that is fixed by a single bolt, it can effectively avoid bolt bending and the tilting of the cutting head 1 caused by bolt bending, and ensure the stability of the working position of the turning edge 2.

[0027] Example 6: This embodiment provides a turning tool with multiple mounting angles, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The tool holder 3 has a socket 30, and the connecting plate 51 has a plug 53 that is compatible with the socket 30; There are two insertion holes 30 and two insertion posts 53, which together form a triangular structure with the second through hole 52. Meanwhile, the insert 53 and the connecting plate 51 can be integrated into one structure.

[0028] As can be seen from this embodiment, the typical arrangement of the insertion hole 30 and the insertion post 53 improves the ease of installation and forms a three-point support with a triangular structure on the connecting plate 51, further improving the structural strength and preventing the locking bolt 50 from tilting during use of the turning tool, thereby improving the turning accuracy and stability.

[0029] Example 7: This embodiment provides a turning tool with multiple mounting angles, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The end of the insert 53 away from the connecting plate 51 is hemispherical.

[0030] As can be seen from this embodiment, by setting the end of the insertion post 53 away from the connecting plate 51 to a hemispherical shape, a guide taper is naturally formed by the arc surface. When there is a slight misalignment between the insertion post 53 and the socket 30, the hemispherical surface can automatically correct the position by sliding the contact point, guiding the insertion post 53 to accurately embed into the socket 30 without the need for repeated manual calibration, which can further improve the convenience of the insertion post 53 and the socket 30.

[0031] Example 8: This embodiment provides a turning tool with multiple mounting angles, which, in addition to the technical solutions of the above embodiments, also has the following technical features: The tool holder 3 has a countersunk hole 31 on the bottom wall of the mounting groove 4, and the countersunk hole 31 is coaxially opened with the first through hole 10. A spring 6 is installed in the countersunk hole 31, and the spring 6 is sleeved on the locking bolt 50.

[0032] As can be seen from this embodiment, by opening the countersunk hole 31 on the tool holder 3 and installing the spring 6 in the countersunk hole 31, when disassembling the tool head 1, after the locking bolt 50 is removed, the spring 6 pushes the tool head 1 to move up appropriately, thereby facilitating the removal of the tool head 1 and improving the convenience of replacing the tool head 1.
