Lathe contour spherical polishing device

Abstract

This utility model discloses a lathe-based contour spherical polishing device. The device includes a tool post mounting support, the lower part of which is mounted on the lathe tool post. A contour spherical base plate is mounted on the upper part of the tool post mounting support. Sanding belt clamping plates are located on both sides of the contour spherical base plate. Sanding belt is positioned between the sanding belt clamping plates and the contour spherical base plate. The top of the contour spherical base plate has a contour inner spherical surface. The sanding belt is tightly adhered to the contour inner spherical surface of the contour spherical base plate and pressed firmly by the sanding belt clamping plates. This lathe-based contour spherical polishing device utilizes bakelite material to create the contour spherical base plate. The sanding belt is then tightly adhered to the contour inner spherical surface of the contour spherical base plate and pressed firmly by the sanding belt clamping plates. This ensures that the sanding belt remains in close contact with the spherical workpiece during polishing, guaranteeing uniform force on the sanding belt and resulting in a consistent polishing effect.

Description

Technical Field

[0001] This utility model belongs to the technical field of polishing devices, specifically relating to a lathe-based contour spherical polishing device. Background Technology

[0002] Polishing is a machining method that uses polishing tools to reduce the surface roughness of a workpiece, thereby obtaining a bright and smooth surface. In machining, polishing tools are frequently used to polish workpieces to achieve the surface roughness required by the drawings.

[0003] Currently, the polishing tool used for spherical workpieces on lathes is an abrasive belt. Because the surface to be polished is spherical, the worker needs to continuously move the abrasive belt back and forth around the workpiece to ensure complete polishing. Furthermore, due to manual operation, the abrasive belt experiences uneven pressure during polishing, resulting in inconsistent polishing effects. This polishing technique is complex, time-consuming, labor-intensive, and makes spherical polishing very troublesome. Therefore, we have conducted research and improvements based on this, proposing a lathe-based contour spherical polishing device. Utility Model Content

[0004] The purpose of this invention is to provide a lathe-based spherical polishing device that solves the problem of uneven force on the abrasive belt during spherical polishing, which leads to inconsistent polishing results.

[0005] The technical solution adopted by this utility model is a lathe contour spherical polishing device, including a tool post mounting support. The lower part of the tool post mounting support is mounted on the lathe tool post, and the upper part of the tool post mounting support is mounted on a contour spherical substrate. There are sanding belt clamping plates on both sides of the thickness of the contour spherical substrate, and there is a sanding belt between the sanding belt clamping plates and the contour spherical substrate.

[0006] The feature of this utility model is that, Furthermore, the tool holder mounting support has a mounting boss at its lower part.

[0007] Furthermore, the upper part of the tool holder mounting support has a U-shaped groove and a connecting hole a.

[0008] Furthermore, the top of the tool holder mounting bracket has an arc, and the two sides have a first inclined plane and a second inclined plane that are tangent to the arc.

[0009] Furthermore, the material of the spherical substrate is bakelite.

[0010] Furthermore, the lower part of the contoured spherical substrate has a connection hole b.

[0011] Furthermore, the bottom of the contoured spherical substrate has an arc, and the two sides have inclined surfaces three and four that are tangent to the arc.

[0012] Furthermore, the contoured spherical substrate is installed in the U-shaped groove of the tool holder mounting bracket and connected by reamed bolts inserted into the connecting holes a and b.

[0013] Furthermore, the contoured spherical substrate can be rotated around the tool holder mounting bracket via the hinged hole bolts.

[0014] Furthermore, the arc at the top of the tool holder mounting support and the inclined surfaces on both sides tangent to the arc, as well as the arc at the bottom of the contoured spherical substrate and the inclined surfaces on both sides tangent to the arc, can prevent interference when the contoured spherical substrate rotates around the tool holder mounting support at a certain angle.

[0015] Furthermore, the upper part of the contoured spherical substrate has sand belt clamping plate engagement holes a, preferably 3 to 5, and they are evenly distributed along the pitch circle.

[0016] Furthermore, the top of the contoured spherical substrate has a contoured inner spherical surface, which is adapted to the surface of the spherical workpiece. The size of the contoured inner spherical surface can be adapted to the different diameters of the spherical workpieces that need to be polished.

[0017] Furthermore, the sanding belt is tightly attached to the inner spherical surface of the contoured spherical substrate and pressed together by the sanding belt clamping plates on both sides.

[0018] Furthermore, the sand belt clamping plate has concentric arc surfaces on its upper and lower sides.

[0019] Furthermore, the sanding belt clamping plate has a clamping hole b in the middle, preferably 3 to 5 clamping holes b, which are evenly distributed along the pitch circle. The number and position of the clamping holes b are the same as the clamping holes a on the contoured spherical substrate.

[0020] Furthermore, the concentric arc surfaces on the upper and lower sides of the sanding belt clamping plate ensure that the sanding belt clamping plate does not protrude beyond the inner spherical surface of the contoured spherical substrate when clamping the sanding belt, thus preventing the sanding belt clamping plate from scratching the spherical workpiece.

[0021] The beneficial effects of this utility model are: The present invention relates to a lathe with a contour spherical polishing device. By selecting bakelite material to process a contour spherical substrate, and then tightly attaching the sanding belt to the contour inner spherical surface of the contour spherical substrate and pressing it with a sanding belt clamping plate, the sanding belt can always be in close contact with the spherical workpiece during polishing, thereby ensuring that the sanding belt is subjected to uniform force during polishing and that the spherical polishing effect is consistent. The contoured spherical substrate is installed in the tool holder mounting bracket using reamed bolts. The tool holder mounting bracket is then clamped by the lathe tool holder, allowing the contoured spherical polishing device to move back and forth with the lathe tool holder. This enables repeated polishing of the spherical workpiece. The operation is simple and solves the problems of existing polishing technologies, which require workers to continuously move the abrasive belt around the workpiece to ensure complete polishing. Furthermore, the manual operation results in uneven force on the abrasive belt, leading to inconsistent polishing effects. Additionally, the operation is complex, time-consuming, labor-intensive, and cumbersome, making spherical polishing extremely difficult. This device is highly automated, requires no real-time worker control, saves time and effort, and reduces labor intensity.

[0022] This invention provides a lathe-based contour spherical polishing device that makes spherical polishing more convenient. Attached Figure Description
