[0030] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. The drawings illustrate typical embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. It should be understood that the embodiments of this utility model and the specific features thereof are detailed descriptions of the technical solutions of this application, and not limitations thereof. Where there is no conflict, the embodiments of this utility model and the technical features thereof can be combined with each other.
[0031] Example 1
[0032] refer to Fig. 3-5 The curved glass grinding head 100 of this utility model is used to fix the glass when grinding the convex surface of the glass. The top of the glass is a concave surface, and the bottom of the glass is a convex spherical arc surface. The curved glass grinding head 100 includes a rigid rotating clamping member 110 made of rigid material and a soft conforming sleeve 120 made of flexible material.
[0033] The soft conforming sleeve 120 wraps around the rigid rotary clamping member 110 and conforms to its shape, and is bonded and fixed to the rigid rotary clamping member 110. After wrapping around the rigid rotary clamping member 110, the soft conforming sleeve 120 can be inserted into the concave surface of the glass and conformally fitted to it. Specifically, the soft conforming sleeve 120 completely conforms to the bottom surface and circumferential sidewalls of the rigid rotary clamping member 110. The shape of the bottom of the rigid rotary clamping member 110 conforms to the concave shape of the glass, only slightly smaller, and the soft conforming sleeve 120 fills the gap formed by the size difference between the two.
[0034] Preferably, the soft conforming sleeve 120 is an injection molded part obtained by coating the hard rotating clamping member 110 with glue, baking it, and then placing it in an injection mold. The inner cavity of the injection mold is consistent with the outer shape of the hard rotating clamping member 110 and is slightly larger in size.
[0035] Preferably, the soft contour sleeve 120 is made of silicone. It has a high temperature resistance of 150°C-180°C and a hardness of 50A-80A. Due to its inherent properties, silicone can be used to create contoured structures according to the product structure. The rigid rotary clamping component 110 is a hardware component. Hardware components can be divided into regular and irregular structures. Hardware components can be made of steel or aluminum. The silicone and hardware components are bonded together using hot-curing silicone rubber adhesive. This hot-curing silicone rubber adhesive is used for bonding uncured silicone rubber to rigid substrates such as metal, nylon, ABS, PC, and PVC, for example, 7708A / 7708B.
[0036] The process structure of the silicone and hardware combination in this embodiment can simultaneously meet the high-precision connection between the hardware and the equipment, and the silicone will not scratch or damage the glass products, thus improving the yield of glass polishing.
[0037] For specific structural features of the rigid rotary clamping component 110, please refer to Fig. 6 At the same time, combined Fig. 3-4 , Fig. 3-4 The middle view is from the bottom of the rigid rotary clamping component 110. Fig. 6 This is a top view of the rigid rotary clamping member 110. The rigid rotary clamping member 110 is generally cylindrical, with a shaft hole 114 at the center of its top surface for connection to a rotating shaft, allowing it to rotate under the shaft's influence. Multiple positioning claws 112 protrude downwards from the bottom surface of the rigid rotary clamping member 110 facing the glass. These positioning claws 112 are distributed in a ring along the edge of the bottom surface of the rigid rotary clamping member 110; in this embodiment, there are three positioning claws 112. The shape of each positioning claw 112 conforms to the concave contour of the glass, and when fitted with a soft conforming sleeve 120, it fits snugly against the concave surface of the glass. Alternating grooves are formed between adjacent positioning claws 112 to allow the polishing fluid to flow and prevent accumulation. In addition, the top surface of the rigid rotary clamping member 110 is offset from its center to form a positioning hole 115, which is used to position the rigid rotary clamping member 110 with the mold during injection molding of the soft mold sleeve 120, so as to ensure that the three positioning claws 112 of the three rigid rotary clamping members 110 are aligned vertically with the recesses at the bottom of the mold cavity corresponding to the three positioning claws 112.
[0038] Preferably, the circumferential sidewall of the rigid rotary clamping member 110 is recessed to form a glue-pulling groove 111, so that the soft conforming sleeve 120 and the rigid rotary clamping member 110 are more tightly fastened together and less likely to fall off. The shape and number of glue-pulling grooves 111 are not limited. Specifically, in this embodiment, the circumferential sidewall of the rigid rotary clamping member 110 is cylindrical, and the glue-pulling groove 111 is an annular groove located in the middle of the circumferential sidewall and surrounding the central axis of the rigid rotary clamping member 110.
[0039] The following describes a feasible manufacturing process for this embodiment: First, according to the product design drawings, manufacture the hardware parts. Then, through various machining processes, complete the vulcanization mold. Silicone raw materials are mixed, preferably with a vulcanizing agent added at a ratio of 0.4%. Next, apply glue to the hardware parts and bake at 100°C for 3-5 minutes. Then, place the hardware parts into the vulcanization mold, add an appropriate amount of silicone raw material, and perform high-temperature vulcanization to form the product. The mold temperature is set at 180°C, the vulcanization time is 300 seconds, the vulcanizing machine pressure is 120 MPa, and the venting is performed 3 times. After the product is formed, remove the waste material around the product and demold to obtain the press head.
[0040] The advantages of this embodiment are as follows: By using a specific adhesive for high-temperature vulcanization, the silicone and metal parts are combined. This results in a product that precisely matches the design and tools, and the silicone will not scratch the glass upon contact. The silicone encapsulates the metal parts, allowing them to conform to the concave surface of the glass, thus increasing the fit between the pressure head and the glass. Furthermore, the softness of the silicone acts as a buffer during rotary grinding, preventing glass breakage and increasing the friction between the pressure head and the smooth glass, allowing for optimal glass rotation and maximizing the grinding effect.
[0041] Example 2
[0042] Understandably, the number of positioning claws 112 can be adjusted, as can the size of the clearance slot. (Reference) Fig. 7 The main difference between this embodiment and Embodiment 1 is that the number of positioning claws 112 is simplified to two, and two clearance grooves 113 are formed between the two positioning claws 112. The shape and contour of the positioning claws 112 only need to conform to the concave surface of the glass.
[0043] Example 3
[0044] This embodiment discloses a curved glass fine grinding device, which can be combined with... Fig. 3-5 and Fig. 1 , 2 Understandably, the curved glass grinding apparatus of this embodiment includes... Fig. 1-2 The grinding base 3 shown is Fig. 3 The curved glass grinding head 100 is shown. The top of the grinding base 300 is a spherical arc surface, the radius of which is much larger than the radius of the convex surface of the bottom of the glass. The grinding head 100 fits perfectly into the concave surface of the glass 100. The shaft hole at the top of the grinding head 100 is also shown.
[0045] In summary, the curved glass fine grinding head and fine grinding device of this utility model have the following beneficial effects: The fine grinding head used in this utility model includes a hard rotating clamping component made of rigid material and a soft conforming sleeve made of flexible material; the soft conforming sleeve wraps around the hard rotating clamping component and conforms to it, and the soft conforming sleeve is bonded and fixed to the hard rotating clamping component; after the soft conforming sleeve wraps around the hard rotating clamping component, it can be inserted into the concave surface of the glass and conforms to it, thus increasing the fit between the head and the glass. In addition, the soft material provides a buffer during the rotating fine grinding, preventing the glass from breaking, and increasing the friction between the head and the smooth glass, so that the glass can be fully rotated, thereby maximizing the fine grinding effect.
