Description

Technical Field

[0001] This utility model relates to the field of grinding and polishing machine production technology, and in particular to a swing mechanism for a single-axis grinding and polishing machine. Background Technology

[0002] With the continuous development of the manufacturing industry, the requirements for the surface processing quality of workpieces are becoming increasingly stringent. Single-axis grinding and polishing machines, as a common surface processing equipment, play a crucial role in the grinding and polishing of materials such as metals, ceramics, and glass. However, traditional single-axis grinding and polishing machines often suffer from limited processing range and uneven processing quality. To address these issues, the swing mechanism was developed. The swing mechanism allows the grinding and polishing head to oscillate within a certain range, thereby expanding the processing range of the workpiece surface. This flexibility enables single-axis grinding and polishing machines to adapt to workpieces of different shapes and sizes, improving the equipment's versatility and adaptability. Through the movement of the swing mechanism, the grinding and polishing head can perform more uniform grinding and polishing on the workpiece surface, reducing localized over-grinding or under-grinding during processing. This helps improve the surface finish and consistency of the workpiece, enhancing product quality. The oscillation of the swing mechanism helps disperse the cutting forces during grinding and polishing, reducing scratches and damage caused by concentrated cutting forces, protecting the workpiece surface from damage. Swing mechanisms typically have an adjustable design, allowing users to easily adjust parameters such as the oscillation amplitude and frequency according to the specific requirements of the workpiece and processing needs. This flexibility facilitates more precise and efficient processing. In modern single-spindle grinding and polishing machines, the swing mechanism is often combined with an advanced control system to achieve automated control and remote monitoring. This helps reduce the risk of human intervention and misoperation, improving production efficiency and safety.

[0003] The existing swing mechanism of single-axis grinding and polishing machines is not convenient for changing the contact point between the working surface of the grinding and polishing machine and the parts in actual use, and it is not convenient for realizing more complex grinding or polishing paths.

[0004] A search of existing patents reveals a single-axis polishing machine swing mechanism (Publication No.: CN210938763U) comprising a main swing rod, a cylinder, a ejector pin, a main swing shaft, a swing shaft seat, a universal joint, a secondary swing rod, a swing rod seat, a handwheel, a lead screw, and a stud. The main swing rod has an ejector pin at its end and is connected to the secondary swing rod via a universal joint. The main swing rod is connected to the main swing shaft, which is mounted on the swing shaft seat. A cylinder is mounted on the swing shaft seat, and the cylinder's output end is connected to the main swing rod. The secondary swing rod is mounted on the swing rod seat and contacts the stud. The stud is threadedly connected to the lead screw, and a handwheel is fitted at the end of the lead screw. Through the transmission between the main and secondary swing shafts, the position of the ejector pin can be easily and quickly changed, thereby altering the ejector pin's movement trajectory to meet design requirements and resulting in polished products with better aperture quality.

[0005] While the aforementioned patent achieves the advantages of conveniently and quickly changing the position of the ejector pin and improving product quality, it cannot reduce the temperature of the workpiece surface.

[0006] Therefore, it is necessary to invent a single-axis grinding and polishing machine swing mechanism that can realize complex grinding paths and reduce the surface temperature of workpieces to solve the above problems. Utility Model Content

[0018] (III) Beneficial Effects

[0019] This utility model provides a swing mechanism for a single-axis grinding and polishing machine, which has the following beneficial effects:

[0020] 1. The swing mechanism of this single-axis polishing machine, through the arrangement of the swing assembly and polishing head, allows the motor to drive the turntable to rotate on the surface of the positioning plate during workpiece polishing. The groove in the middle of the swing arm engages with the circular protrusion on the surface of the turntable, making horizontal movement, which in turn causes the polishing head to move back and forth, achieving fine polishing of the workpiece surface. The swing motion of the polishing head allows it to more comprehensively cover the workpiece surface, reducing the phenomenon of missed polishing and over-polishing, which helps to achieve more uniform material removal and finer surface treatment, thereby improving the processing quality and efficiency of the product.

[0021] 2. The swing mechanism of this single-axis grinding and polishing machine, through the setting of heat dissipation components and anti-splash rings, allows the water pump to draw water from the water tank to the grinding and polishing table before the workpiece is ground and polished. The anti-splash ring prevents coolant and debris generated during the grinding process from splashing, enabling operators to more accurately observe and control the grinding and polishing process. This helps improve operational safety and reduce the possibility of accidents. The cooling water acts directly on the grinding and polishing area, quickly absorbing and carrying away a large amount of heat, preventing the workpiece from deforming due to overheating and affecting the processing quality. The efficient heat dissipation function ensures the stability and continuity of the grinding and polishing process, helps to keep the workpiece temperature within a reasonable range, and extends the service life of the grinding and polishing head and other related equipment.
