Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, and in particular to a micro-vibration assisted cutting device for mechanical parts processing. Background Technology

[0002] Micro-vibration assisted cutting devices are commonly used in the field of precision machining of mechanical parts. During machining, they can generate high-frequency micro-vibrations in the tool or workpiece, improve chip formation, reduce cutting force, thereby improving surface quality, extending tool life, and also assisting in the cutting of difficult-to-machine materials, providing strong support for the manufacturing of high-precision parts.

[0003] In practical applications, existing micro-vibration-assisted cutting devices, used in conjunction with piezoelectric ceramic elements and control systems, can meet the basic requirements for machining mechanical parts. However, the following problems still exist:

[0004] When machining tubular components using a micro-vibration-assisted cutting device, certain deviations inevitably occur during positioning due to the relatively thin outer wall of the tubular parts. Furthermore, the use of micro-vibration for cutting assistance can cause resonance on the cutting surface of the tubular component, affecting the cutting effect and reducing work efficiency. Therefore, this application provides a micro-vibration-assisted cutting device for machining mechanical parts to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a micro-vibration-assisted cutting device for machining mechanical parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a micro-vibration assisted cutting device for machining mechanical parts, comprising a machining table and a micro-vibration cutting component disposed on the side of the machining table;

[0007] A positioning assembly is placed at the bottom of a micro-vibration cutting component. The positioning assembly includes a protective shell mounted on the top of a machining table. A mounting bracket is fixedly connected to the inner wall of the protective shell. A connecting plate is slidably connected to the side of the mounting bracket. A support plate is fixedly connected to the side of the connecting plate. A limiting plate is fixedly connected to the end of the connecting plate away from the support plate. A first sliding rod is slidably connected to the inner cavity of the limiting plate. A second sliding rod is provided on the side of the first sliding rod.

[0008] A clamping assembly is located at the end of the first slide rod away from the limiting plate, and the clamping assembly includes a support rod fixedly connected to one end of the first slide rod.

[0009] Furthermore, a sliding groove is provided on the side of the limiting plate, one end of the first sliding rod extends into the inner cavity of the sliding groove, one end of the first sliding rod is slidably connected to the inner cavity of the sliding groove, one end of the first sliding rod is fixedly connected to a sliding block, a fixing plate is fixedly connected to the side of the support plate near the limiting plate, and the side of the sliding block is slidably connected to the side of the fixing plate near the limiting plate.

[0010] The technical effect of adopting the above technical solution is that the movement trajectory of the first sliding rod can be limited by the cooperation of the sliding block and the fixed plate.

[0011] Furthermore, a second connecting rod is fixedly connected to one end of the second slide rod, and a first connecting rod is rotatably connected to the side of the second connecting rod away from the second slide rod.

[0012] The technical effect of adopting the above technical solution is that, through the cooperation of the first connecting rod and the second connecting rod, the second sliding rod can be made to move outward of the limiting plate.

[0013] Furthermore, a mounting base is fixedly connected to one end of the support rod, and a spring is fixedly connected to the outer surface of the mounting base.

[0014] The technical effect of adopting the above technical solution is that by setting up a spring sheet, the stress generated by clamping can be buffered. At the same time, during the micro-vibration cutting process, the frequency of vibration can be buffered to avoid resonance.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] The bottom of the positioning assembly is equipped with a driving component. In use, the tubular part to be processed is first fitted onto the outer surface of the second slide rod. Then, the motor located on the side of the connecting plate is started. The motor's output shaft rotates clockwise, thereby driving the limiting plate to move counterclockwise via the connecting plate. This, in turn, drives the first slide rod to move along the inner cavity of the slide groove towards the center of the limiting plate. Simultaneously, as the limiting plate moves counterclockwise, it drives the end of the second connecting rod away from the limiting plate to move counterclockwise. When the second connecting rod moves counterclockwise, it drives one end of the first connecting rod to move counterclockwise along the side of the support plate. The connecting rod and the second connecting rod cooperate to move the second sliding rod outward of the limiting plate. When the second sliding rod and the first sliding rod move to a certain position, the outer surface of the flexible clamping plate is in contact with the inner and outer walls of the tubular part, respectively, thereby achieving the positioning and clamping effect of the tubular part and avoiding positional deviation of the tubular part during processing, which could lead to damage. After positioning is completed, the micro-vibration cutting component is activated to perform micro-vibration cutting on the part. During the micro-vibration cutting process, the flexible clamping plate and the spring sheet cooperate to buffer the vibration to a certain extent and avoid resonance during the cutting process.

[0025] 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.

[0026] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a micro-vibration assisted cutting device for machining mechanical parts, a machining table 1, and a micro-vibration cutting component 11 disposed on the side of the machining table 1;

[0027] Positioning component 2 is placed at the bottom of micro-vibration cutting component 11. Positioning component 2 includes a protective shell 21 installed on the top of machining table 1. A mounting bracket 22 is fixedly connected to the inner wall of the protective shell 21. A connecting plate 23 is slidably connected to the side of the mounting bracket 22. A support plate 28 is fixedly connected to the side of the connecting plate 23. A limiting plate 24 is fixedly connected to the end of the connecting plate 23 away from the support plate 28. A first slide rod 25 is slidably connected to the inner cavity of the limiting plate 24. A second slide rod 212 is provided on the side of the first slide rod 25.

[0028] A clamping assembly 3 is positioned at the end of the first slide rod 25 away from the limiting plate 24. The clamping assembly 3 includes a support rod 32 fixedly connected to one end of the first slide rod 25. A groove 29 is formed on the side of the limiting plate 24. One end of the first slide rod 25 extends into the inner cavity of the groove 29 and is slidably connected to the inner cavity of the groove 29. A sliding block 26 is fixedly connected to one end of the first slide rod 25. A fixing plate 27 is fixedly connected to the side of the support plate 28 near the limiting plate 24. The side of the sliding block 26 is slidably connected to the side of the fixing plate 27 near the limiting plate 24. A second connecting rod 211 is fixedly connected to one end of the second slide rod 212. The second connecting rod 211 is located away from the second... A first connecting rod 210 is rotatably connected to one side of the slide rod 212. The end of the second connecting rod 211 away from the second slide rod 212 is rotatably connected to the side of the limiting plate 24 near the connecting plate 23. The end of the first connecting rod 210 away from the second connecting rod 211 is rotatably connected to the side of the support plate 28 near the limiting plate 24. A driving component is provided at the bottom of the positioning assembly 2. In use, the tubular part to be processed is first placed on the outer surface of the second slide rod 212. Then, the motor located on the side of the connecting plate 23 is started. The motor's output shaft rotates clockwise, thereby driving the limiting plate 24 to move counterclockwise through the connecting plate 23. This, in turn, drives the first slide rod 25 along the inner groove 29. The effect of the cavity moving towards the center of the limiting plate 24 is that when the first slide rod 25 moves, the sliding block 26 and the fixed plate 27 cooperate to limit the movement trajectory of the first slide rod 25, preventing the position of the first slide rod 25 from deviating. At the same time, when the limiting plate 24 moves counterclockwise, it can drive the end of the second connecting rod 211 away from the limiting plate 24 to move counterclockwise. When the second connecting rod 211 moves counterclockwise, it can drive the end of the first connecting rod 210 to move counterclockwise along the side of the support plate 28. Through the cooperation of the first connecting rod 210 and the second connecting rod 211, the second slide rod 212 can be moved towards the outside of the limiting plate 24. When the second slide bar 212 and the first slide bar 25 move to a certain position, the outer surface of the flexible clamping plate 31 is respectively attached to the inner and outer walls of the column part, thereby achieving the positioning and clamping effect of the column part and avoiding positional deviation of the column part during processing, which could lead to damage. After positioning is completed, the micro-vibration cutting component 11 is activated to perform micro-vibration cutting on the part. During the micro-vibration cutting process, the flexible clamping plate 31 and the spring piece 33 cooperate to buffer the vibration to a certain extent and avoid resonance during the cutting process. The position of the connecting plate 23 can be fixed by setting the mounting bracket 22.

[0029] Furthermore, such as Figure 2 - Figure 4As shown: One end of the support rod 32 is fixedly connected to the mounting base 34, and the outer surface of the mounting base 34 is fixedly connected to the spring piece 33. When the flexible clamping plate 31 contacts the inner and outer walls of the column part, the spring piece 33 contracts, thereby absorbing the stress generated by the contact, avoiding damage to the thin-walled column during the clamping process, and ensuring the stability of the initial clamping. During micro-vibration cutting, the stress generated by the vibration is transmitted to the spring piece 33 through the flexible clamping plate 31, thereby causing the spring piece 33 to deform further, thus achieving the effect of canceling the vibration frequency and avoiding resonance of the column part during the cutting process.

[0030] During clamping, due to the relatively thin inner and outer walls of the tubular component, over-clamping is unavoidable during the clamping process of the flexible clamping plate 31. Figure 4 As shown: In this solution, a flexible clamping plate 31 is fixedly connected to the top of the spring piece 33. The outer surface of the flexible clamping plate 31 is provided with a certain curvature and is made of flexible material. When clamping, the flexible clamping plate 31 and the spring piece 33 cooperate to further improve the uniform distribution of stress and avoid damage to the inner and outer walls of the column parts due to excessive clamping force during the clamping process.

[0031] Working principle:

[0032] like Figure 1-4 As shown:

[0033] In use: First, the tubular part to be processed is fitted onto the outer surface of the second slide rod 212. Then, the motor located on the side of the connecting plate 23 is started. The output shaft of the motor rotates clockwise, thereby driving the limiting plate 24 to move counterclockwise through the connecting plate 23. This enables the first slide rod 25 to move along the inner cavity of the slide groove 29 towards the center of the limiting plate 24. At the same time, when the limiting plate 24 moves counterclockwise, it drives the end of the second connecting rod 211 away from the limiting plate 24 to move counterclockwise. When the second connecting rod 211 moves counterclockwise, it drives the end of the first connecting rod 210 to move counterclockwise along the side of the support plate 28. Through the first connecting rod 210 and the second connecting rod... The flexible clamp 31 and the first sliding rod 25 work together to move the second sliding rod 212 outward from the limiting plate 24. When the second sliding rod 212 and the first sliding rod 25 move to a certain position, the flexible clamp 31 contacts the inner and outer walls of the column part. At this time, the spring 33 contracts, which can absorb the stress generated by the contact and effectively improve the stability of the clamping. After the positioning is completed, the column part is adjusted to a suitable position by the driving component set at the bottom of the positioning component 2. Then the micro-vibration cutting component 11 is started, so that the part can be micro-vibration cutting. During the micro-vibration cutting process, the flexible clamp 31 and the spring 33 work together to buffer the vibration to a certain extent and avoid resonance during the cutting process.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
