Description

Technical Field

[0001] The present application relates to the technical field of workpiece polishing equipment, and in particular to a polishing device and method for thin valve plates. Background Art

[0002] In the machinery manufacturing, automobile parts processing, hardware products and other industries, the surface quality of thin plate valve workpieces is crucial to the overall performance of the product. In these industries, thin plate valves are usually used in key components such as valves and pump bodies. Their surface roughness, burrs and scratches not only affect the appearance, but may also cause product failure or shorten the life. In order to ensure product quality, companies need efficient and stable polishing processes to deal with these surface defects.

[0003] The relevant thin plate valve disc polishing methods mainly include manual grinding and mechanical equipment polishing. Although manual grinding is flexible, it is inefficient and difficult to ensure quality, which easily leads to large differences in products between batches. Mechanical equipment polishing mostly uses a vibration polishing machine, which mixes the thin plate valve disc with abrasives and achieves polishing under the action of vibration. However, this traditional method has some obvious shortcomings. First, thin plate valve discs are prone to collision with each other during the vibration process, resulting in new defects such as deformation and pits, which seriously affect the polishing quality and consistency. Secondly, when processing a large number of workpieces, traditional vibration polishing machines cannot effectively control the stress conditions of each workpiece, further exacerbating the frequency of quality problems.

[0004] Therefore, the main problem in the related art is: how to improve the polishing efficiency of the thin plate valve plate while avoiding the quality degradation caused by mutual collision, so as to achieve a more stable and efficient polishing effect. Summary of the invention

At the same time, the design of the spring enables the vibration box to vibrate freely within a predetermined range, improving the polishing uniformity and work efficiency of the thin-plate valve plate. Specifically: the elastic component is composed of multiple springs, ensuring multi-point support and enhancing the stability of the system; the design of the lower spring seat and the upper spring seat facilitates the installation and replacement of the spring, while also ensuring the effective fixation of the spring to prevent loosening; one end of the spring is fixed in the lower spring seat, and the other end is fixed in the upper spring seat, forming a stable elastic support system, which effectively isolates the influence of the external structure on the vibration box and improves the polishing quality and production efficiency.

Specifically: the horizontal cylinder drives the horizontal sliding sliding frame, so that the rolling and throwing frame can be accurately positioned at the loading position and the unloading position, ensuring the consistency and accuracy of each loading and unloading process; the lifting cylinder drives the vertical sliding lifting frame to lift and lower, ensuring that the rolling and throwing frame can smoothly enter the vibration chamber for loading or rise from the vibration chamber for unloading, improving the work efficiency of loading and unloading; the clamping assembly is arranged on the lifting frame, and the rolling and throwing frame is fixed by clamping for loading and unloading, preventing shaking or falling off during transportation, and improving the safety and reliability of loading and unloading operations.

When the piston rod of the clamping cylinder retracts the clamping piece to clamp the rolling frame, the inner hole composed of the fixed ring and the movable ring on the rolling frame is supported on the support surface, which increases the contact area with the rolling frame support, further enhances the stability of the clamping, and ensures the safety and reliability of the loading and unloading process.

[0023] In a second aspect, the present application provides a polishing method for a thin valve plate, which adopts the following technical solution: A method for polishing a thin plate valve sheet, based on the above-mentioned polishing device for a thin plate valve sheet, comprises the following steps: S1.

Since the vibration motor 22 is symmetrically arranged on the box body At both ends of 21, the rotation directions of the vibration motors 22 are opposite. When adjusting the angle of the eccentric blocks, the eccentric blocks of the two vibration motors 22 should be 180° reversely configured to maximize the synthetic vibration, thereby increasing the force of the abrasive on the workpiece polishing and significantly improving the polishing efficiency. At the same time, the elastic component 5 between the support plate 213 and the mounting seat 1 is designed to reduce the exciting force transmitted to the mounting seat 1 through the vibration box 2, thereby preventing the attenuation of the exciting force, improving the vibration effect on the vibration box 2, and further improving the production efficiency of workpiece polishing and the consistency of workpiece surface treatment.
