Description

Technical Field

[0001] This utility model relates to a chamfering tool, specifically a chamfering tool for the shank of a vibration-damping tool, belonging to the field of milling cutter technology. Background Technology

[0002] A vibration-damping chamfering tool is a specialized tool that combines vibration damping technology with chamfering functionality. Primarily used in CNC machining, it enhances machining accuracy and tool life. Mounted on CNC machine tools such as milling machines, drilling machines, planers, and chamfering machines, it's used to create chamfers at specified angles on workpiece edges or openings. Through its vibration-damping design, this tool effectively reduces vibration and noise during machining, improving machining accuracy and surface quality. Simultaneously, chamfering removes sharp edges, enhancing workpiece safety and aesthetics, and facilitating subsequent assembly and processing.

[0003] In existing technologies, such as the thread shank chamfering cutter disclosed in CN215468360U, the insert-welded portion includes a cutting tip, a first chamfering edge, a second chamfering edge, a cutting head, a wrench flat, a cutting shank, and a third chamfering edge. The cutting shank is located at the rear of the cutting head, and the wrench flat is located at the tail of the cutting head. The first, second, and third chamfering edges are alternately arranged at the front of the cutting head, with the cutting tip forming the front portion of each edge. The high-speed steel used in the insert-welded portion of the cutting shank increases the tool's toughness, prevents thread shank breakage, and thus improves tool life. The insert-welded portion also reduces the tool's material cost.

[0004] Although the high-speed steel used in the welded part of the tool shank can increase the toughness of the tool and prevent the thread shank from breaking, thereby improving the tool life, and the welded part can also reduce the material cost of the tool, it cannot guide the chamfering tool when feeding it during use, which makes the chamfering tool prone to shaking during feeding, resulting in tool vibration, which is not conducive to chamfering of the workpiece. In view of this, a chamfering tool with an anti-vibration tool shank is provided to overcome the above defects. Utility Model Content

[0005] This invention provides a shank chamfering tool with anti-vibration properties to address the problem that, during use, the chamfering tool cannot be guided, causing it to wobble and vibrate, which is detrimental to the chamfering of the workpiece.

[0006] The present invention achieves the above objectives through the following technical solution: a chamfering tool for a shockproof tool, comprising a chamfering tool holder, a chamfering tool base fixed at one end of the chamfering tool holder, a guide mechanism for guiding the outer surface of the chamfering tool holder, and a chamfering mechanism for chamfering the workpiece on one side of the chamfering tool base;

[0007] The guiding mechanism includes a limiting ring, which is sleeved on the outer surface of the chamfering tool holder. A vibration-damping rubber ring is fixed to the inner wall of the limiting ring, and a limiting slider is fixed to the inner surface of the vibration-damping rubber ring. A limiting groove is slidably connected to one side of the limiting slider on the chamfering tool holder.

[0008] As a further improvement of this utility model: two fixing rods are fixed on one side of the limiting ring, and a fixing block is fixed to the end of each of the two fixing rods.

[0009] As a further embodiment of this utility model: the chamfering mechanism includes a chamfering cutter body, which is installed on one side of the chamfering cutter holder, and a fixing groove is provided inside the chamfering cutter body.

[0010] As a further improvement of this utility model: a fixing bolt is installed inside the fixing groove, and the end of the fixing bolt is threadedly connected to a threaded groove opened on the chamfering tool holder.

[0011] As a further improvement of this utility model: a connecting shaft is fixed to the inner wall of the chamfering cutter body, and a fixed bearing embedded in the chamfering cutter holder is sleeved at the lower end of the connecting shaft.

[0012] As a further improvement of this utility model: a limiting plate is connected to the upper surface of the connecting shaft, and a fixing screw that is threadedly connected to the connecting shaft is installed inside the limiting plate.

[0013] As a further improvement of this utility model: the outer surface of the chamfering tool body is provided with a plurality of scales, and one side of the scales is provided with a scale pointer that is fixedly connected to the chamfering tool holder.

[0014] The beneficial effects of this utility model are: by cooperating with the limiting slider and the limiting groove, the chamfering tool holder is limited and guided, reducing the possibility of the chamfering tool deviating; by using the vibration isolation rubber ring set on the limiting ring, when the chamfering tool shakes slightly, the vibration isolation rubber ring can absorb a certain amount of vibration force, thereby reducing the chamfering tool from vibrating too much and improving its practicality.

[0015] The chamfering tool body can be rotated to adjust its angle, making it convenient for chamfering different workpieces. The angle of adjustment can be observed by using the scale pointer on the chamfering tool body in conjunction with the scale. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] like Figures 1 to 4 As shown, a chamfering tool for a shockproof tool includes a chamfering tool holder 1, a chamfering tool holder 2 fixed to one end of the chamfering tool holder 1, a guide mechanism for guiding the tool on the outer surface of the chamfering tool holder 1, and a chamfering mechanism for chamfering the workpiece on one side of the chamfering tool holder 2.

[0023] The guiding mechanism includes a limiting ring 3, which is fitted onto the outer surface of the chamfering tool holder 1. A vibration-damping rubber ring 31 is fixed to the inner wall of the limiting ring 3, and a limiting slider 32 is fixed to the inner surface of the vibration-damping rubber ring 31. A limiting groove 33 formed on the chamfering tool holder 1 is slidably connected to one side of the limiting slider 32. Two fixing rods 34 are fixed to one side of the limiting ring 3, and fixing blocks 35 are fixed to the ends of both fixing rods 34. The chamfering tool holder 1 is fed by a driving device, thereby causing the chamfering tool holder 2 to... The chamfering cutter body 4 contacts the high-speed rotating workpiece, thereby performing a chamfering operation on the workpiece. Through the setting of the limiting ring 3, with the cooperation of the limiting slider 32 and the limiting groove 33, the chamfering cutter holder 1 can be limited and guided, effectively reducing the possibility of the chamfering cutter deviating. Through the vibration isolation rubber ring 31 set on the limiting ring 3, when the chamfering cutter shakes slightly, the vibration isolation rubber ring 31 can absorb a certain amount of vibration force, thereby reducing the chamfering cutter from vibrating too much and improving its practicality. Example 2

[0024] In addition to all the technical features included in Embodiment 1, this embodiment also includes: a chamfering mechanism comprising a chamfering cutter body 4, the chamfering cutter body 4 being mounted on one side of the chamfering cutter holder 2, a fixing groove 41 being provided inside the chamfering cutter body 4, a fixing bolt 42 being installed inside the fixing groove 41, the end of the fixing bolt 42 being threadedly connected to a threaded groove 43 provided on the chamfering cutter holder 2, a connecting shaft 44 being fixed to the inner wall of the chamfering cutter body 4, a fixing bearing 45 being sleeved on the lower end of the connecting shaft 44 and embedded in the chamfering cutter holder 2, a limiting plate 46 being connected to the upper surface of the connecting shaft 44, a fixing screw 47 being threadedly connected to the connecting shaft 44 being installed inside the limiting plate 46, and a plurality of scale gauges 6 being provided on the outer surface of the chamfering cutter body 4. The scale pointer 5 is fixedly connected to the chamfering tool holder 2 on one side of the scale 6. After loosening the fixing bolt 42 through the fixing groove 41 on the chamfering tool body 4, the fixing bolt 42 and the threaded groove 43 are separated, thereby releasing the fixation of the chamfering tool body 4. At this time, with the cooperation of the connecting shaft 44 and the fixed bearing 45, the chamfering tool body 4 can be rotated, thereby adjusting the angle of the chamfering tool body 4 to facilitate chamfering different workpieces. With the help of the scale pointer 5 on the chamfering tool body 4 and the scale 6, the adjusted angle of the chamfering tool body 4 can be observed. By unscrewing the fixing screw 47 on the limit plate 46, the chamfering tool body 4 can be disassembled for easy replacement.

[0025] Working Principle: Before using the anti-vibration chamfering tool, first connect and fix the chamfering tool holder 1 to the output shaft of the drive device, and connect the fixing rod 34 to the housing of the drive device. Fix the fixing block 35 to the drive device using screws, thereby limiting the chamfering tool's position. During use, the drive device feeds the chamfering tool holder 1, causing the chamfering tool body 4 on the chamfering tool holder 2 to contact the high-speed rotating workpiece, thus performing a chamfering operation. The limiting ring 3, in conjunction with the limiting slider 32 and the limiting groove 33, can limit and guide the chamfering tool holder 1, effectively reducing the possibility of the chamfering tool deviating. The vibration-damping rubber ring 31 on the limiting ring 3 further protects the chamfering tool from slight shaking. When in motion, the vibration isolation ring 31 can absorb a certain amount of vibration force, thereby reducing the large vibration of the chamfering cutter and improving its applicability. By loosening the fixing bolt 42 through the fixing groove 41 provided on the chamfering cutter body 4, the fixing bolt 42 and the threaded groove 43 are separated, thereby releasing the fixation of the chamfering cutter body 4. At this time, with the cooperation of the connecting shaft 44 and the fixing bearing 45, the chamfering cutter body 4 can be rotated, thereby adjusting the angle of the chamfering cutter body 4, which is convenient for chamfering different workpieces. Furthermore, with the help of the scale pointer 5 provided on the chamfering cutter body 4 and the scale 6, the adjusted angle of the chamfering cutter body 4 can be observed. By unscrewing the fixing screw 47 on the limit plate 46, the chamfering cutter body 4 can be disassembled, making it convenient for the chamfering cutter body 4 to be replaced.
