Description

Technical Field

[0001] The utility model relates to the technical field of grinding processing, in particular to a grinding oscillator and grinding equipment. Background Art

[0002] Ultra-finishing is a high-precision processing technology that is widely used in various industrial fields, including precision machinery, optical instruments, semiconductor manufacturing, etc. Through the repeated movement of the grinding head acting on the workpiece to be processed, extremely high-precision grinding and polishing of the workpiece surface is achieved to achieve the finish and precision that meet the specific process requirements. Grinding equipment is usually equipped with an oscillator. The oscillator plays a key role in the grinding equipment and can generate vibrations of a certain frequency and amplitude, thereby driving the grinding head to act on the workpiece. In practice, especially when processing complex workpieces with high precision requirements, the oscillator is often adjusted to a certain angle during the processing process according to the process to be processed. Therefore, the oscillator often has a mechanism that can achieve angle adjustment. In the prior art, the adjustment of the oscillator angle is usually achieved through a mechanical structure, a hydraulic system or an electric adjustment mechanism. The core requirement is to ensure that the adjustment process is smooth and accurate; after adjustment, the most widely used fixing method in the prior art is to lock through a worm gear structure to prevent the angle from changing, and cooperate with regular inspection and calibration of the oscillator angle to ensure that it maintains a relatively accurate grinding effect. However, as the grinding industry's requirements for workpiece precision increase, the traditional oscillator angle fixing method has certain defects: as the oscillator is constantly oscillating during processing, the worm gear structure cannot be completely locked, and slight changes in the angle will still occur during the processing process. In the scenario of ultra-precision grinding, the final accuracy rate of the workpiece is affected. Utility Model Content

[0019] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0020] First, combine Figures 1-2 Description The grinding oscillator according to the embodiment of the utility model is widely used in various ultra-precision grinding processing scenarios such as precision parts manufacturing, optical element processing, etc. In this embodiment, an oscillator used to drive the grinding head 6 in an ultra-crystal grinding device is used as an example for description.

[0021] like Figures 1-2 As shown, the grinding oscillator of the embodiment of the utility model comprises a base 1 , an angle adjustment mechanism 3 , and a fastening mechanism 4 .

[0022] Specifically, Figures 1-2 As shown, an oscillating component 2 is provided on the base 1, and the oscillating component 2 includes a first driver 21, which provides the power required for the entire oscillating component 2 to generate reciprocating vibration. The first driver 21 can be a motor, which drives the oscillating component 2 to generate an oscillating motion and then drives the grinding head 6 to grind the workpiece to be processed; the angle adjustment mechanism 3 is arranged on the base 1. When it is necessary to adjust the relative position and angle of the grinding head 6 and the workpiece, by adjusting a certain inclination angle, after further fixing, the output end 31 of the angle adjustment mechanism 3 is connected to the external grinding head 6, so that the relative position of the grinding head 6 and the workpiece is determined at a preset angle, and then further processed; the fastening mechanism 4 locks the output end 31 to the base 1, and the fastening mechanism 4 locks the output end 31 of the oscillator through a mechanical clamping force, further reinforcing the position of the adjusted angle, and the prior art relies on the original meshing force of the angle adjustment mechanism 3. The locking and fixing method of this embodiment has a more uniform force distribution of the clamping force and a more stable effect, which can better resist the vibration and impact force during the grinding process, and avoid slight deviations caused by vibration in actual processing.

[0023] Preferably, if Figures 1-2 As shown, the angle adjustment mechanism 3 includes an engaging self-locking portion, which limits the displacement of the output end 31. The angle adjustment and locking mechanisms are integrated to reduce the overall volume of the oscillation mechanism, and the overall flexibility of the grinding head 6 is stronger during actual processing.

[0024] Preferably, if Figures 1-2As shown, the angle adjustment mechanism 3 includes a worm wheel 33 and a worm 34. A second driver 32 is provided at the end of the worm 34. The meshing self-locking portion includes a thread provided on the worm 34 and a gear tooth provided on the turbine. When the worm 34 stops rotating, due to the friction angle and the thread angle between the worm wheel 33 and the worm 34, the worm wheel 33 will automatically lock in the current position and will not rotate by itself due to external force. This self-locking performance makes the angle adjustment mechanism 3 have higher reliability when it is necessary to maintain a fixed angle. The structure can also withstand larger loads and torques.

[0025] Preferably, if Figures 1-2 As shown, the fastening mechanism 4 is ring-shaped and sleeved on the output end 31. The ring can evenly distribute the clamping force around the output end 31, avoiding the problem of local stress concentration, so that the output end 31 of the entire angle adjustment mechanism 3 and the clamping transmitted to the entire turbine mechanism are centrally symmetrical, and the stability is stronger in the subsequent grinding process; in addition, this uniform distribution helps to reduce deformation and damage of components and improve the durability of the system.

[0026] Preferably, if Figures 1-2 As shown, the fastening mechanism 4 increases the pressure of the base 1 and the output end 31 by 5 to 10 bar. Within the pressure range of 5 to 10 bar, the fastening mechanism 4 can apply sufficient clamping force to ensure that the connection between the base 1 and the output end 31 is stable and reliable, meeting the working scene requirements of various workpieces to be processed and effectively reducing the precision loss caused by loose or moving parts.

[0027] Preferably, if Figures 1-2 As shown, the fastening mechanism 4 is a clamp. The design of the clamp enables the clamping and releasing operations to be completed quickly. This ability to respond quickly is particularly important for occasions that require frequent adjustments or quick replacement of parts, and can effectively improve work efficiency. The clamp usually has a compact structure and can provide a strong clamping force without taking up too much space. The additional arrangement at the output end 31 only occupies a small space and does not affect the original layout of the entire mechanical equipment, and has strong flexibility. In addition, the structure of the clamp fixing mechanism is relatively simple, so it is more convenient to maintain and replace parts, and the loss of the original worm wheel 33 and worm 34 is reduced to a certain extent. Since the replacement and maintenance costs of the internal worm wheel 33 and worm 34 are relatively high, the addition of the clamp to a certain extent reduces the overall maintenance cost of the entire oscillator.

[0028] Preferably, if Figures 1-2 As shown, the fastening mechanism 4 is an annular clamp, and the pressure increase of the clamp is 6 bar. Whether it is necessary to clamp small precision parts or large heavy objects, the pressure increase of 6 bar can provide sufficient clamping force to meet different work requirements. It is a cost-effective selection solution that meets the demand conditions.

[0029] Preferably, if Figures 1-2As shown, an encoder 5 is provided on one side of the angle adjustment mechanism 3. The encoder 5 records the rotation angle of the output end 31 of the adjustment mechanism, and can more accurately record the angle adjustment state of the entire processing process.

[0030] When in use, the base 1 serves as a stable foundation for the entire system, carrying and supporting other components. The angle adjustment mechanism 3 is arranged on the base 1. When necessary, the relative position and angle between the grinding head 6 and the workpiece are adjusted. By adjusting a certain inclination angle and fixing it automatically after the adjustment is completed, the output end 31 of the angle adjustment mechanism 3 is connected to the external grinding head 6, thereby ensuring that the relative position between the grinding head 6 and the workpiece is at a preset angle, which is convenient for subsequent processing operations. The fastening mechanism 4 is responsible for locking the output end 31 to the base 1, ensuring that the relative position is locked after the angle adjustment, and maintaining the stability of the subsequent processing process. It locks the output end 31 of the oscillator through mechanical clamping force, which is more reliable than relying solely on the original meshing force of the angle adjustment mechanism 3.

[0031] Above, refer to Figures 1-2 The grinding vibrator according to the embodiment of the utility model is described. The clamp fixing method is intuitive and simple. The operator can quickly and accurately adjust the angle and fix the vibrator without affecting the processing efficiency. The position of the oscillator is locked by mechanical clamping force, replacing the original meshing force. This force distribution is more even and can better resist the vibration and impact force during the grinding process. In addition, the structure of the clamp fixing mechanism is relatively simple, so it is more convenient to maintain and replace parts, and the loss of the original worm wheel 33 and worm 34 is reduced to a certain extent. Since the internal worm wheel 33 and worm 34 themselves have high replacement and maintenance costs, the addition of a clamp to a certain extent reduces the overall maintenance cost of the entire oscillator.

[0032] Secondly, combined Figure 3 Describe another embodiment according to the utility model, as Figure 3 As shown, a grinding device is provided, including a grinding oscillator, a grinding head 6, and the grinding head 6 is connected to the output terminal 31. Due to the stability of the clamp and the precise control of the oscillator, the grinding process using the device has higher consistency, which is particularly important for application scenarios requiring high-precision grinding.

[0033] Preferably, the grinding device further comprises a frame, and the base 1 comprises a bottom plate 11, the bottom plate 11 is connected to the frame, and the frame provides relative position constraint and control for the oscillator, as well as reliable force support.

[0034] Above, refer to Figure 3As shown, according to another embodiment of the grinding equipment of the utility model, the clamping force ensures that the grinding head 6 continues to accurately position and stably clamp the workpiece during the grinding process, and the clamping force distribution of the fastening mechanism 4 is more uniform, the effect is more stable, and it can more effectively resist the vibration and impact force generated during the grinding process. In actual processing, this locking method can significantly reduce the slight deviation caused by vibration, thereby improving the accuracy and stability of grinding, providing a guarantee for the improvement of the grinding accuracy of the grinding equipment as a whole, and can effectively improve the overall pass rate of the workpiece in the super-finishing process.
