Description

Technical Field

[0001] This utility model relates to the field of tool vibration damping technology, and in particular to a high-precision tool vibration damping mechanism. Background Technology

[0002] Cutting tools are the actuators used for cutting processes in mechanical manufacturing. They are a key component of the process system. Their core function is to remove material from the workpiece in a controlled manner through relative motion and interaction with the workpiece, so that the workpiece can obtain a predetermined geometric shape, dimensional accuracy, and surface quality.

[0003] During the machining process, if the distance between the tool extension and the clamping point is set too long when the tool is machining the workpiece, it will cause obvious vibration of the tool when it is running at high speed, which will affect the stability of the machining process and have an adverse effect on the surface quality and dimensional accuracy of the workpiece. Traditional tool anti-vibration mechanisms are limited by their structure and cannot adjust the distance between the tool and the clamping point, thus failing to effectively suppress the generation of vibration, exacerbating the instability of the tool during operation and reducing the positioning accuracy of the tool in subsequent machining. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that it is difficult to adjust the distance between the tool and the clamping point and that vibration cannot be effectively suppressed, and to propose a high-precision tool anti-vibration mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-precision tool vibration damping mechanism includes a base plate and a fixed seat. The fixed seat is installed at the end of the base plate, and multiple fixing bolts are inserted at the end of the base plate. A mounting seat is provided inside the fixed seat, and a tool is provided inside the mounting seat. A rotating disk is inserted into the side wall of the fixed seat. A second limiting rod is symmetrically provided inside the fixed seat to limit the position of the mounting seat. Rotating bolts are inserted into the side wall of the fixed seat.

[0006] Preferably, the bottom of the base plate is provided with a rubber shock-absorbing pad, and multiple fixing bolts pass through the base plate and the rubber shock-absorbing pad.

[0007] Preferably, a plurality of mounting bolts are inserted at the end of the mounting base, the mounting bolts pass through the mounting base and are threadedly connected to the tool, a limiting groove is formed in the fixed base, a sliding groove is symmetrically formed on the inner side wall of the limiting groove, and a slider is symmetrically formed on the side wall of the mounting base, and the slider and the sliding groove are mutually adapted.

[0008] Preferably, the fixed seat has a groove, the inner side wall of the groove is provided with a bidirectional lead screw, the end of the rotating disk and the end of the bidirectional lead screw are coaxially connected, the outer side wall of the bidirectional lead screw is symmetrically provided with a movable plate, and the side wall of the movable plate is connected to the end of the second limiting rod.

[0009] Preferably, the side wall of the rotating disk is provided with a plurality of limiting holes, and a first limiting rod is provided in the limiting hole. The first limiting rod passes through the limiting hole and is connected to the side wall of the fixed seat.

[0010] Preferably, the rotating bolt passes through the side wall of the fixed seat and the mounting seat, and multiple positioning rods are inserted into the end of the mounting seat.

[0011] Compared with the prior art, the present invention has the following advantages: 1. This utility model uses a rotating bolt, which the operator rotates to move the mounting base. The mounting base slides in the groove via a slider, adjusting its position within the fixed base. This, in turn, adjusts the distance between the tool and the clamping point. By inserting a positioning rod, the possibility of accidental movement of the mounting base is reduced. The mounting base moves the tool closer to the clamping point, reducing the distance between the tool extension length and the clamping point, effectively reducing vibration and improving the stability of the machining process.

[0012] 2. This utility model, by setting a second limiting rod, allows the operator to rotate the rotating disk, which in turn drives the bidirectional lead screw to rotate. The moving plate moves along the outer wall of the bidirectional lead screw through a threaded hole, and the moving plate drives the second limiting rod to move. The second limiting rod limits and fixes the mounting seat, reducing the shaking of the mounting seat after adjustment and enhancing the stability of the tool during processing. By inserting the first limiting rod, the rotating disk is prevented from rotating unexpectedly during tool processing, thus improving the accuracy of processing. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-5 A high-precision tool vibration damping mechanism includes a base plate 1 and a fixed seat 3. The fixed seat 3 is installed at the end of the base plate 1. Multiple fixing bolts 2 are inserted at the end of the base plate 1. A rubber damping pad 12 is fixedly installed at the bottom of the base plate 1. The multiple fixing bolts 2 pass through the base plate 1 and the rubber damping pad 12. The multiple fixing bolts 2 install the base plate 1 at the end of the equipment through the rubber damping pad 12. This arrangement forms a flexible connection between the base plate 1 and the equipment, buffering the vibration generated during the operation of the equipment and reducing the direct transmission of vibration to the tool 9.

[0017] The fixed base 3 is provided with a mounting base 7, and the mounting base 7 is provided with a cutting tool 9. Multiple mounting bolts 8 are inserted into the end of the mounting base 7. The mounting bolts 8 pass through the mounting base 7 and are threadedly connected to the cutting tool 9. Through the mutual cooperation of the mounting bolts 8 and the mounting base 7, the cutting tool 9 is fixed to the inner side wall of the mounting base 7, reducing the possibility of the cutting tool 9 loosening or shifting during the processing.

[0018] A limiting groove is provided in the fixed seat 3, and a sliding groove 5 is symmetrically provided on the inner side wall of the limiting groove. The slider 15 is symmetrically fixed on the side wall of the mounting seat 7, and the slider 15 and the sliding groove 5 are mutually compatible. Through the mutual cooperation of the slider 15 and the sliding groove 5, the mounting seat 7 slides in the sliding groove 5 via the slider 15, reducing the possibility of the mounting seat 7 shifting during movement.

[0019] The rotating disk 10 is inserted into the side wall of the fixed base 3. The fixed base 3 is symmetrically provided with second limiting rods 14 to limit the position of the mounting seat 7. The fixed base 3 has a groove. The bidirectional lead screw 16 is rotatably disposed on the inner side wall of the groove. The end of the rotating disk 10 and the end of the bidirectional lead screw 16 are coaxially and fixedly connected. The outer side wall of the bidirectional lead screw 16 is symmetrically provided with a moving plate 13. The moving plate 13 has a threaded hole that matches the bidirectional lead screw 16. The moving plate 13 moves on the outer side wall of the bidirectional lead screw 16 through the threaded hole. The side wall of the moving plate 13 and the end of the second limiting rod 14 are fixedly connected. Through the cooperation of the moving plate 13 and the second limiting rod 14, the moving plate 13 drives the second limiting rod 14 to move, limiting the position of the mounting seat 7 and ensuring the stability of the tool 9 during the machining process.

[0020] The rotating disk 10 has multiple limiting holes on its side wall, and a first limiting rod 11 is provided in the limiting hole. The first limiting rod 11 passes through the limiting hole and is connected to the side wall of the fixed seat 3. Through the cooperation between the rotating disk 10 and the first limiting rod 11, the first limiting rod 11 limits the rotating disk 10, reducing the possibility of the bidirectional lead screw 16 rotating unexpectedly during the machining process, which would affect the stability of the tool 9.

[0021] Rotating bolt 4 is inserted into the side wall of fixed seat 3. Rotating bolt 4 passes through the side wall of fixed seat 3 and is rotatably connected to the side wall of mounting seat 7. Multiple positioning rods 6 are inserted into the end of mounting seat 7. Through the cooperation of rotating bolt 4 and positioning rods 6, the machining accuracy and stability of tool 9 are ensured. Rotating bolt 4 adjusts the distance between mounting seat 7 and clamping point by rotating, adapting to the fixing requirements of mounting seat 7 under different machining needs, and enhancing the stability of mounting seat 7.

[0022] The functional principle of this utility model can be explained through the following operation methods: The operator installs the tool 9 in the mounting base 7. The operator connects the tool 9 to the mounting base 7 by threading the mounting bolt 8 through the mounting bolt 8, reducing the possibility of the tool 9 loosening during operation. When it is necessary to adjust the distance between the tool 9 and the clamping point, the operator rotates the rotating disk 10. The rotating disk 10 drives the double-acting screw 16 to rotate. The moving plate 13 moves on the outer wall of the double-acting screw 16 through the threaded hole. The moving plate 13 drives the second limit rod 14 to move, so that the second limit rod 14 limits and fixes the mounting base 7, realizing the adjustment of the distance between the tool 9 and the clamping point. This effectively reduces the vibration phenomenon generated by the tool 9 when it is running at high speed and improves the stability of the machining process. The setting of the first limit rod 11 effectively limits the rotating disk 10, preventing the mechanism from being damaged or the adjustment from failing due to excessive rotation of the rotating disk 10. Multiple fixing bolts 2 pass through the base plate 1 and the rubber damping pad 12, ensuring the stability and reliability of the entire anti-vibration mechanism. The rubber damping pad 12 set at the bottom of the base plate 1 can further absorb and reduce vibration energy, reducing the impact of vibration on the tool 9 and the workpiece. During the installation and adjustment of the tool 9, the mounting base 7 is moved by rotating the bolt 4. The mounting base 7 moves on the inner wall of the slide groove 5 via the slider 15, which reduces the offset when the mounting base 7 moves. By inserting the positioning rod 6, the positioning rod 6 fixes the mounting base 7 a second time, which enhances the positioning accuracy of the tool 9 and enables the tool 9 to maintain a stable posture during the machining process.

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.
