Description

Technical Field

[0001] This invention relates to the field of polishing equipment accessories, specifically to an intelligent magnetic grinding and polishing machine. Background Technology

[0002] Magnetic polishing is a relatively new finishing technology that has emerged in recent years. Traditional magnetic polishing devices use a lower-end electric motor to drive a permanent magnet to rotate and generate a magnetic field. While this method is widely used, traditional magnetic polishing devices have significant drawbacks, primarily: uneven magnetic field distribution, overall weak magnetic field strength affecting polishing efficiency, non-adjustable permanent magnet magnetic field strength, and easy wear of rotating mechanical parts, all of which negatively impact polishing results. Furthermore, the single rotation method of the overall magnet limits its adaptability and hinders widespread adoption.

[0003] Variable magnetorheological fluid polishing utilizes electric current to alter the viscosity of magnetorheological fluids to achieve precision and ultra-precision machining of optical component surfaces. Magnetic finishing, on the other hand, uses the magnetic force exerted by a magnetic field on a strongly magnetic medium to form a magnetic brush, which performs micro-pressure cutting on the inner and outer surfaces of parts. It has better adaptability to complex surfaces, but its grinding efficiency is relatively low. Simply relying on a magnetic field to drive magnetic abrasive grains for polishing results in a relatively soft magnetic brush formed by the magnetic force attracting the abrasive grains, generating less grinding pressure and directly affecting the grinding efficiency of the magnetic abrasive grains.

[0004] The most commonly used equipment in variable magnetofluidity polishing technology is the magnetic field-assisted polishing machine, which includes an abrasive cylinder for mounting the abrasive particles, and the abrasive cylinder is driven to rotate by a motor. Traditional polishing machines use magnetic abrasive grains and magnetic needles as cutting tools to cut the workpiece during operation, and are also called magnetic rotary polishing machines. This type of polishing machine has the following drawbacks: 1) The abrasive cylinder uses a permanent magnet to provide the magnetic field, and the magnetic field strength is not adjustable. If the magnetic field strength needs to be adjusted, permanent magnets of different strengths must be replaced, resulting in high costs; 2) The magnetic field of the permanent magnet is unstable and difficult to control, leading to uneven grinding results; 3) The generated grinding pressure is relatively low, directly affecting the grinding efficiency of the magnetic abrasive grains. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned defects and provide an intelligent magnetic grinding and polishing machine that can change the grinding intensity and improve its flexibility to adapt to different workpieces and processing requirements.

[0006] The objective of this invention is achieved through the following means:

[0007] The intelligent magnetic abrasive polishing machine includes a frame unit and a polishing unit located inside the frame unit. The polishing unit includes a product hanging mechanism and an abrasive cylinder mechanism. The abrasive cylinder mechanism is located directly below the product hanging mechanism and includes a cylinder body, a bearing seat at the bottom of the cylinder body, and a cylinder motor for rotating the cylinder body. The cylinder body has an upward-facing opening and a central tube penetrating the cylinder body at its center. A lower base plate is located at the bottom of the cylinder body, and two or more sets of evenly distributed electromagnet assemblies are arranged between the cylinder body and the lower base plate.

When the revolution motor is working and rotating, it drives the revolution turntable and the revolution gear set to rotate synchronously.

[0013] In the above description, as a preferred embodiment, the rotating assembly includes a rotating shaft passing through the workpiece holder, a rotating disk installed at the bottom of the workpiece holder, and a rotating gear set disposed at the top of the rotating disk.

When the revolving gear set rotates, it drives each workpiece holder to revolve, and simultaneously the revolving gear set drives the rotating gear set and the workpiece holder to rotate synchronously.

[0014] In the above description, as a preferred embodiment, the bottom of the workpiece positioning plate is equipped with two or more downwardly extending adjustment mechanisms. These adjustment mechanisms extend to the edge of the rotating disk, and each mechanism includes two rollers that respectively adhere to the upper and lower edges of the rotating disk. Since the height and position of the two rollers are fixed, when the two rollers clamp the rotating disk, the stability of the rotating disk's rotation is ensured, preventing any deviation and improving the smoothness of the rotating disk's rotation.

[0015] In the above description, as a preferred embodiment, the frame unit is surrounded by a chassis panel unit and a lifting door unit.

It can complete the polishing required for complex curved surfaces that cannot be done by ordinary technology, ensure the grinding quality, enable the magnetic abrasive to move faster, enhance the grinding force, and thus significantly improve the polishing efficiency.

[0019] 2) During the polishing process, the workpiece itself can rotate on its own axis and also revolve around the sun, and their rotation speeds are equal. Multiple workpieces can be polished at the same time, and the polishing effect is uniform and consistent.

[0020] 3) By using variable current technology, the excitation current is changed in real time, thereby forming several alternating magnetic fields in the inner cavity of the cylinder. The grinding process is carried out by alternating rotating magnetic field. The magnetic field strength can be adjusted by the excitation current, thereby changing the grinding intensity and improving the flexibility to adapt to different workpieces and processing requirements.

[0021] 4) The magnetic field is uniformly distributed and the magnetic field strength is easily controlled by adjusting the current. Different magnetic field strengths can be set for different workpiece requirements, which can reduce costs, has strong applicability, and is easy to promote widely. Attached Figure Description
