Description

Technical Field

[0001] This application relates to the technical field of turning parts, and more particularly to a tool holder device. Background Technology

[0002] Lathe machining is a part of mechanical processing. Lathe machining primarily uses cutting tools to machine rotating workpieces. Turning is generally performed on a lathe and is used to machine internal and external cylindrical surfaces, end faces, conical surfaces, shaped surfaces, and threads. During lathe machining, various types of cutting tools are required, resulting in a diverse range of tool types. In practice, some parts cannot be machined using conventional tools, necessitating the development of non-standard tools. Due to the long development cycle of non-standard tools, it is necessary to develop additional tools and tool holders to replace them, reducing the number of non-standard tools required and shortening the development cycle.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0026] To further illustrate the technical means and effects adopted by this application in achieving its intended purpose, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments.

[0027] Please see Figure 1 and Figure 2 This application provides a tool holder device 100 for mounting a cutting tool 200. The tool holder device 100 includes a tool holder 10, a connecting block 60, a plurality of first rotating members 20, and a plurality of second rotating members 30. The connecting block 60 is connected to the end of the tool holder 10. The tool holder device 100 is mounted on the tool holder of a CNC lathe (not shown) turret via the connecting block 60, so that the workpiece 300 can be turned using the cutting tool 200 mounted on the tool holder 10. Figure 4 and Figure 5 .

[0028] The handle 10 has a first surface 11 and a second surface 12 disposed opposite to each other, and a third surface 13 and a fourth surface 14 disposed opposite to each other. The handle 10 has a through hole 15 passing through the first surface 11 and the second surface 12, the through hole 15 being used to accommodate the cutting tool 200. The third surface 13 has a plurality of first mounting holes 16 communicating with the through hole 15, and the fourth surface 14 has a plurality of second mounting holes 17 communicating with the through hole 15. A plurality of first rotating members 20 are used to abut against the surface of the cutting tool 200 through the first mounting holes 16, and a plurality of second rotating members 30 are used to abut against the other surface of the cutting tool 200 through the second mounting holes 17. The plurality of first rotating members 20 and the plurality of second rotating members 30 are used to lock the cutting tool 200 onto the handle 10.

[0029] In this application, the cutting tool 200 is housed within the through hole 15. Multiple first rotating members 20 and multiple second rotating members 30 abut against the opposing outer walls of the cutting tool 200 via first mounting holes 16 and second mounting holes 17, thereby securing the cutting tool 200 to the tool holder 10. Furthermore, the through hole 15 is suitable for various cutting tools 200, and the first rotating members 20 and second rotating members 30 can lock cutting tools 200 of different thicknesses onto the tool holder 10. The tool holder device 100 provided in this application is applicable to various cutting tools 200 (such as standard external turning tools, external grooving tools, or forming tools). The combination of the cutting tool 200 and the tool holder device 100 also helps to reduce the design requirements of the tool holder device 100, expand its applicability, meet the design and use of some non-standard cutting tools 200, and reduce production costs.

[0030] The tool holder device 100 provided in this application can be used to perform internal hole groove 310 turning on the workpiece 300 by mounting a matching standard external turning tool, external grooving tool or forming turning tool on the tool holder device 100. This provides a reliable alternative to the development of non-standard tools 200 that are affected by the cutting range of the standard internal hole groove 310 tool, effectively reducing the development cost of non-standard tools 200 and improving the application range and versatility of the tool holder device 100.

[0031] In some embodiments, the handle 10 has a generally square outline, and the connecting block 60 has an elliptical cross-section. The handle 10 has a first end face 18 and a second end face 19 disposed opposite to each other. The second end face 19 is located at the end of the handle 10 away from the through hole 15, and the end of the connecting block 60 is connected to the second end face 19. In some embodiments, the handle 10 and the connecting block 60 are integrally formed. The area of ​​the second end face 19 is larger than the area of ​​the cross-section of the connecting block 60.

[0032] See Figure 2In some embodiments, the through hole 15 extends through the first end face 18 along the direction from the second end face 19 to the first end face 18, making the through hole 15 open. The through hole 15 is located at the end of the handle 10 and has three openings. The tool 200 can be directly inserted into the through hole 15 through the openings on the first end face 18, facilitating the installation and removal of the tool 200 from the handle 10. This also facilitates the application of tools 200 whose thickness is closer to that of the through hole 15 in the direction perpendicular to the third surface 13 or the fourth surface 14. In some embodiments, the through hole 15 has a general rectangular outline.

[0033] In some embodiments, the number of first mounting holes 16 is the same as the number of second mounting holes 17, and the first mounting holes 16 and second mounting holes 17 correspond one-to-one, with the center lines of a first mounting hole 16 and a second mounting hole 17 collinear. This helps reduce wear on the tool 200 when it is in operation in the tool holder device 100. In some embodiments, along the second end face 19 to the first end face 18, a plurality of first mounting holes 16 are located at the center of the inner wall where the through hole 15 is located, and a plurality of second mounting holes 17 are located at the center of the inner wall where the through hole 15 is located. Thus, in the direction from the second end face 19 to the first end face 18, the first rotating member 20 and the second rotating member 30 can abut against the center of the tool 200, improving the stability of the first rotating member 20 and the second rotating member 30 abutting against the tool 200. The number of first mounting holes 16 and second mounting holes 17 is three each.

[0034] See Figure 2 In some embodiments, multiple first mounting holes 16 are equally spaced, and multiple second mounting holes 17 are equally spaced, so that when the tool 200 is mounted on the tool handle 10, the force exerted on the tool 200 by the first rotating member 20 is more uniform, and the force exerted on the tool 200 by the second rotating member 30 is more uniform, which helps to improve the tightness of the tool 200 mounted on the tool handle 10 and reduce the probability of loosening or displacement during the use of the tool 200.

[0035] In some embodiments, when viewed from a direction perpendicular to the third surface 13 or the fourth surface 14, the centers of the plurality of first mounting holes 16 and the centers of the plurality of second mounting holes 17 are located on the same straight line, with a first mounting hole 16 provided between two second mounting holes 17, and the plurality of first mounting holes 16 and the plurality of second mounting holes 17 are staggered. Thus, the first rotating member 20 and the second rotating member 30 are used to lock the tool 200, further improving the connection force between the tool handle 10 and the tool 200.

[0036] In some embodiments, both the first rotating member 20 and the second rotating member 30 include screws, and the plurality of first mounting holes 16 and the plurality of second mounting holes 17 are threaded holes. The screws and threaded holes cooperate to allow the tool 200 to be detachably locked onto the tool handle 10.

[0037] In some embodiments, both the first mounting hole 16 and the second mounting hole 17 are provided with rounded corners. When the first rotating member 20 and the second rotating member 30 are assembled on the tool holder 10, there is space at the rounded corners of the first rotating member 20 and the second rotating member 30, so that the chips generated between the first rotating member 20 and the second rotating member 30 and the tool 200 are placed in the space, reducing secondary scratches on the tool 200 by the chips.

[0038] See Figure 3 In some embodiments, the handle device 100 further includes an elastic washer 50, which is disposed between the blade 200 and the inner wall of the through hole 15. An elastic washer 50 is also disposed on the side wall of the blade 200 and the through hole 15 to further accommodate blades 200 of different sizes, thus improving the applicability of the handle device 100. The elastic washer 50 has a through hole 51 corresponding to the position of the first mounting hole 16. The first rotating member 20 passes through the through hole 51 and abuts against the blade 200, and the blade 200 is locked to the handle 10 by the second rotating member 30. Furthermore, the elastic washer 50 is disposed on the side of the blade 200 that is farther apart from the blade 200.

[0039] In some embodiments, a friction portion 40 is provided on the inner wall of the through hole 15. The friction portion 40 is located on two opposing inner walls of the through hole 15 to increase the friction force of the tool 200 mounted in the tool holder 10, thereby improving the stability of the tool 200 mounted in the tool holder 10 and reducing the probability of the tool holder 10 falling off the tool 200. In some embodiments, the friction portion 40 may be located on any one or both of the inner walls of the through hole 15. Specifically, the friction portion 40 may be a groove or texture provided on the inner wall, and the groove is arranged along the direction from the first end face 18 to the second end face 19.

[0040] See Figure 4 and Figure 5 The tool holder device 100 is installed on the tool holder of a CNC lathe, which can meet the turning of the inner groove 310 of a ring-shaped workpiece 300 with a diameter >200mm.

[0041] In this application, the cutting tool 200 is housed within the through hole 15. Multiple first rotating members 20 and multiple second rotating members 30 abut against the outer wall of the cutting tool 200 through the first mounting hole 16 and the second mounting hole 17, respectively, thereby securing the cutting tool 200 to the tool holder 10. Furthermore, the through hole 15 is suitable for various cutting tools 200, and the first rotating members 20 and the second rotating members 30 can lock cutting tools 200 of different thicknesses onto the tool holder 10. The tool holder device 100 provided in this application is applicable to various cutting tools 200 (such as standard external turning tools, external grooving tools, or forming tools). The combination of the cutting tool 200 and the tool holder device 100 also helps to reduce the design of the tool holder 10, expand the applicability of the tool holder device 100, meet the design and use of some non-standard cutting tools 200, and reduce production costs.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
