Description

Technical Field

[0001] The utility model belongs to the technical field of magnetorheological polishing, and in particular relates to an improved plane magnetorheological polishing machine. Background Art

[0002] Magnetorheological Finishing (MRF) is an ultra-precision machining method that uses the rheological properties of magnetorheological polishing fluid in a magnetic field for polishing. Magnetorheological fluid is mainly composed of discrete micron-sized magnetic particles, carrier fluid and surfactant. It has the characteristics of magnetic properties, rheological properties and stability.

[0003] Polishing machine is also called grinding machine, which is often used for mechanical grinding, polishing and waxing. Its working principle is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed. Due to the joint action of the polishing disc and the polishing agent and the friction with the surface to be polished, the paint surface pollution, oxide layer and shallow marks can be removed. The speed of the polishing disc is generally 1500-3000r / min, mostly stepless speed change, which can be adjusted at any time according to needs during construction. With the improvement of polishing standards, magnetorheological polishing has gradually become popular. Magnetorheological polishing is an application branch derived from the rheological properties of magnetorheological fluid. Polishing abrasives are added to the magnetorheological fluid. Under the action of the magnetic field, the magnetic particles are mixed with abrasives and slide on the surface of the workpiece, thereby removing the surface material of the workpiece to achieve the polishing effect.

[0004] A Chinese patent application with application number CN202321673256.X discloses a magnetorheological polishing device, including a magnetorheological polishing body, the magnetorheological polishing body including a Y-direction guide rail, an X-direction guide rail and a Z-direction guide rail, a cradle turntable is provided on the X-direction guide rail, a magnetorheological equipment turntable is provided on the cradle turntable, and an optical element to be polished is installed on the magnetorheological equipment turntable; both a probe and a polishing wheel are connected to the Z-direction guide rail; a signal receiver is also installed on the magnetorheological polishing body; the magnetorheological polishing device adds a cradle turntable, and a liftable probe can be used to perform initial coordinate calibration on the optical workpiece. The magnetorheological polishing device can be used to directly polish the optical element to be processed after coordinate calibration, without the need to repeatedly clamp and calibrate the workpiece; the cradle turntable can provide a richer motion trajectory than the polishing equipment in the prior art, so that the polishing of the optical element has higher precision.

[0005] However, since some workpieces are relatively large, it is difficult to move them during processing, which increases the cost of transportation for users, reduces processing efficiency, is inconvenient for users to use, and thus reduces the practicality of the polishing machine. Therefore, we have made improvements to this and proposed an improved planar magnetorheological polishing machine. Utility Model Content

[0006] In view of the above deficiencies in the prior art, the present utility model provides an improved planar magnetorheological polishing machine to solve the problems in the above background art.

[0007] To solve the above technical problems, the present utility model adopts the following technical solutions:

[0008] An improved planar magnetorheological polishing machine includes a support chassis and a vertical frame slidably mounted on the support chassis. The vertical frame is used to install the magnetorheological polishing machine for deep processing of workpieces. The support chassis is of a frame structure, with first slide rail rods installed on both sides and a workbench fixedly installed on the top, and a first driving mechanism longitudinally installed at the bottom. The vertical frame is of a square frame structure, and the bottom plate at the bottom is connected to the first nut of the first driving mechanism. A first sliding sleeve connected to the first slide rail rod is provided inside the vertical frame.

[0009] During the polishing and manufacturing process of workpieces, since the workpieces are relatively large and difficult to move during processing, the handling cost of users is increased, the processing efficiency is reduced, it is inconvenient for users to use, and thus the practicality of the magnetorheological polishing machine tool is reduced. Therefore, we have made improvements and proposed an improved planar magnetorheological polishing machine. Specifically, the magnetorheological polishing machine tool includes a support chassis and a vertical frame. The vertical frame is of a square structure and is slidably mounted on the outside of the support chassis and driven by a first driving mechanism to move on the support chassis. When processing workpieces, they can be directly placed on the workbench of the support chassis. Through the driving of the first driving mechanism, the second driving mechanism, and the third driving mechanism, the magnetorheological polishing machine can automatically polish the workpieces, so that the position of the workpieces does not need to be adjusted manually, which saves manpower and improves the processing efficiency at the same time.

[0010] Further, a second slide rail rod is provided at the top of the vertical frame and a second driving mechanism is horizontally installed. A lifting mechanism is vertically installed on the second slide rail rod, and the magnetorheological polishing machine is connected to the lifting mechanism.

[0011] Further, the lifting mechanism includes a second sliding sleeve and two mounting plates. One of the mounting plates is connected to the second sliding sleeve and connected to the second nut of the second driving mechanism. The magnetorheological polishing machine is installed on the other mounting plate, and a third driving mechanism is connected between the two mounting plates.

[0012] Further, the first driving mechanism, the second driving mechanism, and the third driving mechanism are all screw drive structures.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] 1. By designing a support chassis and an upright frame, where the upright frame is in a rectangular structure with a mouth shape. The upright frame is slidably installed on the outside of the support chassis and is driven by a first driving mechanism to move on the support chassis. When processing a workpiece, it can be directly placed on the workbench of the support chassis. Through the driving of the first driving mechanism, the second driving mechanism, and the third driving mechanism, the magnetorheological polishing machine automatically polishes the workpiece, so that it is no longer necessary to manually adjust the position of the workpiece, which saves manpower and improves the processing efficiency at the same time.
