In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Some embodiments of the utility model provide a rubber grinding head for polishing the plane, the side surface and the concave surface of an optical fiber image transmission element, which comprises a grinding disc, wherein the lower end of the grinding disc is provided with a grinding surface; the lower end surface of the grinding surface is provided with a polishing contact area, and the shape of the polishing contact area corresponds to that of the polishing piece. The grinding surface is closely attached to the polishing contact area of the polishing piece to realize precise polishing.
In some embodiments, optionally, the grinding disc is a cylinder with a diameter of 45-50 mm and a height of 5 mm. The size of the grinding disc is limited by the sizes of the mechanical arm clamping groove and the annular thread clamp, so that the size of a grinding surface is influenced, the number of polishing working areas of the grinding surface is fixed, namely the utilization rate of the grinding head is fixed, the diameter of the grinding disc cannot be larger than the grinding disc clamping groove connected with the mechanical arm and smaller than the inner diameter of the grinding disc annular thread clamp, and the height of the grinding disc annular thread clamp is equal to the height of the grinding disc clamping groove; the diameter of the transition section is not more than the inner diameter of the grinding disc annular threaded clamp.

In some embodiments, optionally, the polishing contact area is a groove and a circular arc surface, and a plane, a fillet, a cylindrical surface or an inclined surface of the optical fiber image transmission element can be polished simultaneously, so that the polishing efficiency is improved, and the polishing time is reduced.
In some embodiments, optionally, the lower end of the ground surface has a groove, and the groove is shaped to match the stepped surface of the optical fiber image transmitting element. The structure can polish the plane of the optical fiber image transmission element and the side surface of the optical fiber image transmission element.
In some embodiments, optionally, the slope of the step surface is 30-90 °, the height is 2-5 mm, the facet diameter of the groove is 18-35 mm, and the intersection of the facet edge of the groove and the slope step surface has an arc angle of R0.5 ± 0.1, which can be matched with the shape height of the optical fiber image transmission element (the size of the image inverter and the optical fiber panel).
In some embodiments, optionally, the lower end surface of the grinding surface has an arc surface corresponding to the arc size of the polishing piece concave surface, so that the concave surface can be precisely polished, and if the arc surface is too large, the size of the polishing piece concave surface is increased, which results in that the customer requirements are not met; if the arc surface is too small, the concave surface of the polishing piece can have a phenomenon that part of the area is missed during polishing.
In some embodiments, the polishing member may optionally be a fiber optic image transfer element.
The rubber grinding head is formed by mixing special rubber and grinding materials. The abrasive is green silicon carbide, and the mixing weight ratio of the special rubber to the abrasive is 10. The silicon carbide rubber grinding head has good wear resistance, the service life of the rubber is prolonged, and the processing cost is reduced.
Compared with the polyurethane polishing sheet with micropore holes, the rubber grinding head of the utility model can not be quickly damaged due to the heat generated by the high-speed (1000-1400 r/min) rotation of the product, and the service life of the rubber grinding head is long. And when the polyurethane polishing sheet is used for polishing, polishing solution needs to be continuously sprayed, so that the production cost is high and the resource is wasted. And the rubber grinding head only needs to spray purified water when in work.
The polishing steps of the rubber grinding head are as follows:
the rubber grinding head is arranged on a mechanical arm of polishing equipment, a polishing piece is clamped by a pneumatic clamping jaw, the size of a clamp and the size of a product of the polishing piece need to be strictly matched, otherwise, collision or overload of the equipment can be caused, and the equipment is damaged. When the grinding surface of the rubber grinding head is close to the polishing piece, the motor is started, the polishing piece rotates around the central shaft of the pneumatic clamping jaw, the surface in contact with the grinding surface is polished, heat is generated when the grinding head rotates at a high speed (1400 revolutions per minute) to polish a circular bead, although the pure water spraying device is opened during polishing, the functions of washing and cooling can be achieved, the abrasion of the grinding head cannot be avoided, and therefore the grinding head needs to be slightly advanced towards the polishing piece at regular intervals. The pure water spray set is one part on the mechanical arm polishing machine, the front end of the pure water spray set is connected with a PVC hose (avoiding touching a polishing workpiece and causing scratch) through a stainless steel thin tube (playing a supporting role), the pure water spray set is polished and cleaned at the side of a polishing contact point, the pure water spray set has the functions of washing polished glass powder and reducing the temperature. The grinding head and the workpiece are regularly and continuously rubbed to obtain polishing, the abrasion of the grinding head cannot be avoided, but the abrasion resistance of the rubber grinding head is superior to that of the polyurethane polishing sheet. After long-time polishing, the contact point of the rubber grinding head is abraded, so that a gap is formed between the rubber grinding head and the polishing piece, and the rubber grinding head cannot abut against the polishing piece.
The present invention is further illustrated by the following specific examples.
