[0002] As an important polishing equipment, the hem machine is widely used in polishing various spherical surfaces. However, the traditional hem machine is designed to polish spherical surfaces with a curvature radius between 0-50. For surfaces outside this range, especially convex spherical surfaces with a curvature radius between 50-60, it is impossible to polish.

[0003] The existence of this problem undoubtedly limits the application scope of the hem machine and also affects its use effect in some industries. Therefore, improving the versatility of the hem machine so that it can adapt to spherical polishing operations with a wider range of curvature radii has become an urgent problem to be solved.

[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0017] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be used as limitations on the present invention. As used in the specification and appended claims of the present invention, the singular expressions "a", "an", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context.

[0018] References to "one embodiment" or "some embodiments" etc. described in this specification mean that one or more embodiments of the utility model include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0019] Example 1: See Figure 1-3 A polishing ornament for optical lens processing includes a connecting handle 100 connected to the main shaft of the polishing equipment, a support platform 200 is arranged at the upper end of the connecting handle 100, and an inner concave surface is arranged on the top surface of the support platform 200, and the inner concave surface is covered with an abrasive layer 201; the connecting handle 100 is detachably connected to the main shaft of the polishing equipment, and the curvature radius of the inner concave surface is within 50-60mm.

[0020] In a possible implementation, Figure 3 As shown, the main shaft connecting end 300 of the polishing device is a tubular structure, and the connecting end 300 is detachably connected to the connecting handle 100 through a thread; the outer end of the connecting end 300 has a threaded structure, and a nut 202 is rotatably provided on the connecting handle 100, which can be tightened to the main shaft of the polishing device. When connecting, the connecting handle 100 is inserted into the connecting end 300, and the nut 202 is tightened to fix it.

[0021] In this embodiment, a support platform 200 is fixed to the upper end of the connecting handle 100. The top of the support platform 200 is not completely flat, but is designed with an inner concave surface, and the inner concave surface is evenly covered with an abrasive layer 201. When the polishing device is running, the main shaft drives the connecting handle 100 to rotate, and then the abrasive layer 201 on the support platform 200 polishes the lens. The design of the inner concave surface allows the abrasive layer 201 to better fit the surface of the lens during polishing, thereby improving the polishing effect.

[0022] Example 2: See Figure 3-4 On the basis of Example 1, a plurality of positioning ridges 101 are arranged at the bottom end of the connecting handle 100 along its axial direction, and a slot 301 for slidingly inserting and cooperating with each positioning ridge 101 is arranged in the connecting end 300. When the connecting end 300 is connected and cooperated with the connecting handle 100, the positioning ridge 101 is located in the slot 301.

[0023] In a possible implementation, three positioning ridges 101 are added to the bottom end of the connecting handle 100 along its axial direction. These positioning ridges are evenly spaced and have a certain elasticity. Three slots 301 are correspondingly opened inside the connecting end 300 of the main shaft of the polishing device. The width of the slot is slightly larger than the width of the positioning ridges, so that the positioning ridges can be smoothly inserted into the slots. When the connecting handle 100 is connected to the connecting end 300, the positioning ridges 101 will slide into the corresponding slots 301, playing a role in positioning and anti-rotation.

[0024] The connection stability between the connecting handle and the spindle connection end is enhanced by adding positioning convex strips and slots, which prevents the connection from loosening or falling off due to vibration or excessive torque during polishing.

[0025] In a specific solution, the protruding thickness of the positioning convex strip 101 is gradually reduced from top to bottom, so as to form a positioning inclined surface 111 at the bottom end of the positioning convex strip 101, and a guiding inclined surface 311 is provided in the slot 301 corresponding to the positioning inclined surface 111 and in sliding contact with it. That is, the bottom end of the positioning convex strip 101 is designed as an inclined surface, and the corresponding slot 301 is also provided with a guiding inclined surface, so that the two inclined surfaces can be pressed together to reduce the radial displacement of the connecting handle 100 during connection.

[0026] Example 3: Figure 2 As shown, the surface of the abrasive layer 201 is provided with a plurality of cutouts 211, which are arranged in a ring shape along the center of the abrasive layer 201, and a complete grinding area is left at the center of the abrasive layer 201. The cutouts 211 are mainly used for chip removal to avoid the accumulation of debris during the grinding process. This chip removal mechanism not only improves the efficiency of polishing, but also reduces quality problems such as uneven polishing or scratches caused by the accumulation of debris.

[0027] In a possible implementation manner, the opening size of the cutout 211 is gradually increased from the inside to the outside, and the outer end of the cutout 211 passes through the outer edge of the abrasive layer 201 .

[0028] The outer end of the cutout 211 completely penetrates the outer edge of the abrasive layer 201 to form an open structure.

[0029] The opening design of the cutout 211 gradually increases from the inside to the outside, and its penetrating structure at the outer edge of the abrasive layer, is mainly intended to reduce the accumulation of debris generated during the grinding process inside the cutout. As the cutout opening gradually increases, they can more effectively accommodate and guide the gradually increasing debris particles, preventing the debris from clogging and accumulating inside the cutout. When the debris reaches the outer end of the cutout, since the cutout penetrates the outer edge of the abrasive layer, the debris can be smoothly discharged from the cutout, further reducing the debris residue on the polishing ornament.

[0030] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
