Problems solved by technology

[0003] The above-mentioned polishing technology has outstanding effectiveness for polishing large-sized aspheric optical parts, but there are certain problems in polishing relatively small-sized high-steep conformal optical parts and free-form surface optical parts, especially for conformal The inner surface of optical parts, due to the size limitation of the polishing tool, cannot enter the cavity of the part, so it is difficult to achieve effective polishing of the inner surface
Liquid jet polishing (FJP) technology is suitable for internal polishing of the cavity, but this technology has the characteristics of low efficiency and difficult correction of intermediate frequency errors, so this technology is also difficult to achieve effective high-steep conformal optical parts and free-form surface optical parts. polishing

Embodiment 1

[0043] Such as figure 1As shown, an embodiment of a tire polishing device for inner and outer surfaces of high-steep parts and free-form surfaces of the present invention, the tire polishing device includes a mounting platen 1, a driving mechanism 2, a driving wheel 3, a contact wheel 4, and a polishing belt 5 and the long-armed support arm 6. The driving mechanism 2 is installed on the installation platform 1 . The driving wheel 3 is connected to the output end of the driving mechanism 2, and the polishing belt 5 is wound on the driving wheel 3 and the contact wheel 4. During processing, the polishing belt 5 wound on the contact wheel 4 acts on the workpiece with a certain pressure The surface is polished. The outer edge of driving wheel 3 and contact wheel 4 is all covered with the rubber material of certain thickness, plays the effect of cushioning and preventing polishing belt 5 from slipping. One end of the support arm 6 is fixed on the installation table 1, and the ot...

Embodiment 2

[0053] Such as figure 2 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that the trimming mechanism includes a second driving cylinder 91 and a trimming wheel 92 installed on the mounting platen 1, and the driving end of the second driving cylinder 91 The end is provided with a trimming block 93 with consolidated abrasives. During trimming, the polishing belt 5 is wound around the dressing wheel 92, and the second driving cylinder 91 pushes the trimming block 93 to be compressed on the polishing belt 5 to realize sharpening; the guide wheel 7 is 4, and the installation position of guide wheel 7 and the winding way of polishing belt 5 have done corresponding change. When the polishing belt 5 does not need to be sharpened, the winding method of the polishing belt 5 is as follows: image 3 shown.

Embodiment 3

[0055] Such as Figure 4 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that: the trimming mechanism and the in-position measuring part 10 are removed; the guide wheel 7 is one, and the driving wheel 3, the guide wheel 7 and the tension mechanism The installation position and the winding way of the polishing belt 5 have been changed accordingly.

Abstract

A wheel and belt polishing device for inner and outer surfaces and free-form surfaces of high-steepness parts comprises a mounting bedplate, a driving mechanism, a driving wheel, a contact wheel, a polishing belt and a long supporting arm. The driving mechanism is mounted on the mounting bedplate, the driving wheel is connected with an output end of the driving mechanism, the polishing belt is wound on the driving wheel and the contact wheel, one end of the supporting arm is fixed onto the mounting bedplate, the other end of the supporting arm extends out of the mounting bedplate and can extend into an inner cavity of a workpiece, and the contact wheel is mounted at the end of the supporting arm extending out of the mounting bedplate. The invention further discloses a machine tool which comprises a tool body. The wheel and belt polishing device for inner and outer surfaces and free-form surfaces of high-steepness parts is arranged on the tool body. By the wheel and belt polishing device and the machine tool, the inner cavity of the part can be polished conveniently, and polishing efficiency is high.

Description

technical field [0001] The invention mainly relates to the field of ultra-precision machining machinery and equipment, especially the field of polishing equipment, in particular to a wheel polishing device and machine tool suitable for the inner and outer surfaces and free-form surfaces of ultra-precision high-steep parts. Background technique [0002] With the rapid development of modern optical technology and computer technology, the application of complex optical components in optical system design is increasing. In the optical system, the application of complex optical components can significantly reduce the number of parts, reduce the weight of the system, reduce the overall size, and can significantly improve the technical performance of the optical system, so complex optical components have broad application prospects in the optical system. However, the processing and manufacturing of complex optical components is relatively difficult, which limits the wide applicatio...
