Description

Technical Field

[0001] This utility model relates to the field of tool docking and installation technology, specifically to an alloy tool that is easy to dock and install. Background Technology

[0002] Alloy cutting tools possess numerous superior properties, such as high hardness, high wear resistance, good heat resistance, and chemical stability. They are used in various CNC machine tools for metal cutting operations of various shapes, including turning, milling, drilling, and gear cutting, covering a wide range of metal material processing industries such as engineering machinery, machine tool manufacturing, general machinery, automotive parts, mold processing, rail transportation, high-end equipment manufacturing, military manufacturing, and aerospace.

[0003] Existing alloy cutting tool mounting systems generally employ simple clamping and limiting devices. These devices only limit the tool torque through basic mechanical clips or bolt fastening, and their anti-torque and anti-loosening designs have significant flaws. In actual machining processes, especially under harsh conditions such as high-speed cutting, intermittent cutting, or heavy-load machining, insufficient rigidity or gaps at the tool-holder interface can lead to "micro-rotation." This unstable connection can cause the tool to gradually loosen, exhibiting increased radial runout and axial movement, potentially resulting in complete tool displacement or even sudden detachment, posing serious safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide an alloy cutting tool that is easy to install, and to solve the following technical problems: the existing alloy cutting tool installation generally adopts a simple clamping and limiting device. This device only limits the torque of the tool through basic mechanical buckles or bolt fastening, and its anti-torque and anti-loosening design has obvious defects.

[0005] The objective of this utility model can be achieved through the following technical solution: an alloy cutting tool that is easy to install, comprising a tool body and a mounting block, wherein a connecting block is fixedly provided at one end of the tool body, and a docking block is fixedly provided at one end of the connecting block, wherein the mounting block has a groove at one end of the tool body that matches the connecting block, and a slot adapted to the docking block is provided inside the mounting block at the lower end of the groove, wherein sliding grooves are symmetrically provided on the inner wall of the mounting block, and a limiting mechanism is provided in the sliding groove, wherein the limiting mechanism is used to limit the displacement of the tool body.

[0006] As a further embodiment of this utility model: the limiting mechanism includes a limiting pin slidably disposed inside the sliding groove, a limiting plate fixedly sleeved on the outer side of the limiting pin, an mounting plate fixedly disposed on one end sidewall of the sliding groove, and limiting grooves symmetrically opened at the upper end of the docking block.

[0007] As a further embodiment of this utility model: a first spring is sleeved on the limiting pin and fixed between the limiting plate and the mounting plate.

[0008] As a further embodiment of this utility model: the docking block includes a cylinder fixedly disposed at one end of the connecting block, and a plurality of rectangular blocks are fixedly disposed in a ring array on the outer side of the cylinder.

[0009] As a further embodiment of this utility model: the mounting block has symmetrical arc-shaped grooves at one end near the tool body, and the mounting block has a snap-fit ​​mechanism at one end near the tool body. The snap-fit ​​mechanism includes a moving rod that is slidably connected inside the arc-shaped groove. One end of the moving rod is provided with a retaining ring, and the other end of the moving rod is movably sleeved with a pull rod. The outer side of the connecting block has symmetrical slots that match the retaining ring.

[0010] As a further embodiment of this utility model: the end of the pull rod is fitted with a return spring fixed on the inner wall of the moving rod and the side wall of the pull rod.

[0011] As a further embodiment of this utility model: the upper end of the retaining ring is designed with a wedge shape, and the opposing surfaces of the two retaining rings are inclined surfaces.

[0012] As a further embodiment of this utility model: a guide block is fixedly provided on the outer side surface of the connecting block, and a guide groove is longitudinally provided on the end side wall of the mounting block.

[0013] The beneficial effects of this utility model are:

[0014] (1) This utility model achieves quick insertion and precise positioning of the tool by setting a mating block and slot, a retaining ring and an arc groove on the alloy tool connection structure. The structure is simple, easy to operate and highly practical. By adding a limiting mechanism and a snap-fit ​​mechanism, the radial and axial displacement of the mating block and the connecting block relative to the mounting block can be effectively constrained, thereby automatically completing the axial locking of the tool body after insertion, greatly reducing the manual adjustment steps, significantly improving the assembly efficiency, and ensuring the installation accuracy and connection stability.

[0015] (2) The precise fit between the mating block and the slot, and the retaining ring and the arc groove in this utility model form an efficient anti-torsional rigid constraint system. The tenon joint system significantly enhances the anti-torsional and anti-shear performance of the alloy tool, effectively avoiding the "micro-rotation" caused by rigidity defects or assembly gaps in the alloy tool, thereby ensuring the stability and long-term reliability of the alloy tool under high-frequency vibration and complex cutting conditions.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0028] In the field of alloy cutting tool technology, insufficient rigidity or gaps at the interface between the alloy cutting tool and the tool holder significantly impact its operational stability and reliability. This invention addresses the problems of unstable connections and poor torsional resistance in traditional alloy cutting tools by providing an alloy cutting tool that facilitates docking and installation. Through a series of innovative designs, it achieves a reliable connection between the tool and the tool holder, improving the operational stability of the alloy cutting tool and ensuring its stability and long-term reliability under high-frequency vibration and complex cutting conditions. The specific implementation method is as follows:

[0029] like Figure 1 - Figure 3 An alloy cutting tool that is easy to install includes a tool body 1 and a mounting block 2. A connecting block 3 is fixedly provided at one end of the tool body 1, and a docking block 4 is fixedly provided at the end of the connecting block 3 away from the tool body 1. The mounting block 2 has a groove 21 that matches the connecting block 3 at one end of the tool body 1. The lower end of the groove 21 has a slot 22 that matches the docking block 4 inside the mounting block 2. The circular cross-section of the groove 21 is larger than the cross-section of the slot 22 and is tangent to the cross-section corresponding to the slot 22. The groove 21 and the slot 22 are connected. The inner wall of the mounting block 2 has symmetrical sliding grooves 23. A limiting mechanism 5 is provided in the sliding groove 23. The limiting mechanism 5 is used to limit the displacement of the tool body 1.

[0030] The carbide tool can be quickly installed by engaging and fixing the docking block 4 with the slot 22. The slot 22 can effectively constrain the rotation of the docking block 4, thereby preventing the tool from loosening or shifting during use and ensuring stability under load. The matching design of the slot 22 and the docking block 4 does not require complicated adjustments. Alignment can be completed by direct insertion, which greatly shortens the assembly time.

[0031] like Figure 4The limiting mechanism 5 includes a limiting pin 51 that is slidably disposed in a sliding groove 23 on the inner side wall of the mounting block 2. A limiting plate 52 is fixedly sleeved on the outer side of the limiting pin 51. The limiting plate 52 is slidably disposed in the sliding groove 23. An mounting plate 53 is fixedly disposed on one side wall of the sliding groove 23. The middle part of the mounting plate 53 is slidably connected to the limiting pin 51. A first spring 54 is sleeved on the outer surface of the limiting pin 51. One end of the first spring 54 is fixedly connected to the limiting plate 52, and the other end of the first spring 54 is fixedly connected to the mounting plate 53. Limiting grooves 43 are symmetrically opened on the docking block 4. The limiting grooves 43 match the limiting pins 51.

[0032] When limiting the tool body 1, during the locking phase, pulling the limiting pin 51 backward causes the limiting plate 52 to compress the first spring 54, causing the limiting pin 51 to retract into the sliding groove 23. At this time, the docking block 4 can freely insert into the slot 22. After docking is completed, the limiting pin 51 is released, the first spring 54 releases its elastic potential energy, and pushes the limiting pin 51 into the limiting groove 43, limiting the horizontal displacement of the docking block 4 and achieving stable fixation. During the disassembly phase, pulling the limiting pin 51 again to disengage from the limiting groove 43 allows for quick separation of the tool.

[0033] like Figures 5-7 The mounting block 2 has symmetrically formed arc-shaped grooves 24 at one end near the tool body 1. A locking mechanism 6 is provided inside the mounting block 2 at the end near the tool body 1 to restrict the rotation of the tool body 1. The locking mechanism 6 includes a moving rod 61 slidably connected inside the arc-shaped groove 24. One end of the moving rod 61 is provided with a retaining ring 62, and the other end of the moving rod 61 is movably sleeved with a pull rod 63. The pull rod 63 extends to the outer surface of the mounting block 2. A second spring 64 is sleeved on the outer surface of the moving rod 61, and one end of the second spring 64 is fixedly connected to the retaining ring 62. Then, the other end of the second spring 64 is connected to the side wall of the arc groove 24. The outer side of the connecting block 3 is symmetrically provided with slots 31. The retaining ring 62 matches the slot 31. The end of the pull rod 63 is provided with a return spring 65 inside the moving rod 61. One end of the return spring 65 is fixedly connected to the inner side wall of the moving rod 61, and the other end is sleeved on the pull rod 63 and connected to the side wall of the pull rod 63. The return spring 65 is used to ensure that the pull rod 63 is always in close contact with the side wall of the mounting block 2 during operation, thereby avoiding motion interference of the sliding pull rod 63 on the working process of the alloy tool.

[0034] During docking, align docking block 4 with the inside of slot 22 and press docking block 4 firmly. During the pressing process, connecting block 3 moves two retaining rings 62 outward. The retaining rings 62 slide backward inside the arc groove 24, and the second spring 64 is compressed, storing elastic potential energy. Pull rod 63 slides inside moving rod 61. When docking block 4 is tightly fitted with slot 22 and can no longer move, retaining ring 62 is engaged inside the arc groove 24, thereby restricting the displacement and rotation of tool body 1. During disassembly, pull rod 63 on the outer wall of mounting block 2 is pulled outward. Pull rod 63 compresses return spring 65, thereby moving retaining ring 62 out of the arc groove 24, releasing the restriction of arc groove 24 on retaining ring 62, thus completing the disassembly and assembly of tool body 1 and mounting block 2.

[0035] like Figure 7 The upper end of the retaining ring 62 is designed with a wedge shape, and the inclination angle of the wedge shape is 15°±0.5°. The two retaining rings 62 are arranged in a mirror symmetrical manner to form a self-centering system. The retaining ring 62 is an arc-shaped structure, and the size of the arc is just right to fit the arc groove 24. Through the guidance of the wedge-shaped structure, the insertion resistance is reduced by more than 40%.

[0036] The arc-shaped surface of the inner wall of the arc-shaped groove 24 and the arc-shaped structure of the outer contour of the retaining ring 62 form a precise fit, enabling quick snap-fit ​​fixing of the connecting block 3 and the mounting block 2. The wedge-shaped structure at the upper end of the retaining ring 62, with its 15° inclined guide surface, effectively decomposes vertical pressure during assembly, guiding the mating block 4 to smoothly move downwards along a preset trajectory, reducing insertion resistance by more than 40%. Simultaneously, this structure employs a self-locking design, relying on the geometric constraints and elastic deformation between components to achieve quick insertion and locking. Compared to traditional installation methods, the assembly efficiency of a single component is improved by nearly 60%.

[0037] like Figure 2 The docking block 4 includes a cylinder 41 fixedly disposed at one end of the connecting block 3. Multiple rectangular blocks 42 are fixedly disposed in a ring array on the outer side of the cylinder 41. The extending direction of the rectangular blocks 42 is the same as the axial direction of the cylinder 41.

[0038] like Figure 2The cylinder 41 and rectangular block 42 cooperate with the slot 22 to form a tenon system. The planar contact forms a torsional rigid constraint, which directly prevents the axial rotation of the tool under the action of cutting torque. This effectively avoids the phenomenon of "micro-rotation" caused by insufficient rigidity or gaps in the traditional method of relying solely on limit block clamping. This ensures that the tool will not deviate under the action of cutting force. During use, the alloy tool mainly bears the main cutting force (accounting for 60% to 80% of the total cutting force). The main cutting force directly determines the cutting power consumption and the mechanical stress of the tool edge. The cylinder 41 mainly bears the radial force (such as centrifugal force and back force), and the rectangular block 42 mainly bears the main cutting force and circumferential torque. The high compressive strength of the planar contact resists the shear stress, improves the installation accuracy, and ensures the normal use of the alloy tool.

[0039] like Figure 1 , Figure 2 A guide block 32 is fixedly provided on the outer side surface of the connecting block 3, and a guide groove 25 is longitudinally provided on the end side wall of the mounting block 2;

[0040] During docking, guided by the guide block 32 and the guide groove 25, the tool body 1 is rotated so that the guide block 32 and the guide groove 25 are on the same straight line, which can quickly complete the snap-fit ​​and fixation of the docking block 4 and the slot 22, significantly improving the installation efficiency and making it highly practical.

[0041] In summary, an alloy cutting tool that facilitates docking and installation involves aligning the docking block 4 with the groove 21 at the end of the mounting block 2 during docking. The rotation angle of the tool body 1 is adjusted by the guide block 32 on the outer side of the connecting block 3 and the guide groove 25 on the side wall of the mounting block 2. The docking block 4 moves into the groove 21, and the end of the docking block 4 presses against the wedge-shaped inclined surface at the upper end of the retaining ring 62, causing the retaining ring 62 to move backward and compress the return spring 65. When the docking block 4 enters the retaining groove 22, the pull-back limiting pin 51 causes the limiting plate 52 to compress the first spring 54, causing the limiting pin 51 to retract into the sliding groove 23, thus completing the docking of the docking block 4 with the retaining ring 65. When the slot 22 is engaged, the retaining ring 62 and the arc-shaped slot 24 are also engaged and fixed. During disassembly, it is only necessary to release the restrictions of the limiting mechanism 5 and the engaging mechanism 6 to complete the disassembly of the alloy tool. When the alloy tool is in use, the precise cooperation between the mating block 4 and the slot 22, and the retaining ring 62 and the arc-shaped slot 24, constructs an efficient anti-torsional rigid constraint system. The tenon joint system significantly enhances the anti-torsional and anti-shear performance of the alloy tool, effectively avoiding the "micro-rotation" caused by rigidity defects or assembly gaps in the alloy tool, thereby ensuring the stability and long-term reliability of the alloy tool under high-frequency vibration and complex cutting conditions.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
