Description

Technical Field

[0001] This application relates to the technical field of glass processing, and in particular to glass clamps. Background Technology

[0002] In the process of glass research and development or production, it is necessary to test the performance parameters of glass such as refractive index, light absorption rate and transmittance. Before testing, the surface of the glass sample needs to be ground and polished to ensure that the surface smoothness and quality of the glass sample meet the standards.

[0003] In the traditional glass sample grinding and polishing process, workers usually need to hold the glass sample and press it against the grinding and polishing disc of the ring polisher with considerable force. However, since the grinding and polishing of glass samples takes a long time, workers will experience arm discomfort from pressing the sample against the grinding and polishing disc for a long time, which increases the labor intensity of the workers. Utility Model Content

[0004] Therefore, it is necessary to provide a glass clamp to address the problem that traditional techniques require workers to exert force for a long time to press the sample onto the ring polisher, which causes arm discomfort and increases the labor intensity of workers.

[0005] The technical solution is as follows:

[0006] One embodiment provides a glass clamp, comprising:

[0007] The mounting base has a through mounting channel;

[0008] The loading component has a loading space for accommodating glass samples. The loading component is located in the mounting channel and can reciprocate along the axial direction of the mounting channel so that the loading component can drive the glass sample to contact or move away from the polishing disc.

[0009] And a counterweight mechanism, which is located on the side of the mounting base away from the polishing disc and presses against the loading member to give the loading member a tendency to move toward the polishing disc.

[0010] In use, the glass clamp described above involves placing the glass sample in the loading space of the loading component. Under the pressure of the counterweight mechanism, the loading component moves along the axis of the mounting channel of the mounting base and gradually approaches the polishing disc, thereby moving the glass sample and bringing it into contact with the polishing disc. During the grinding and polishing process, the glass sample adheres tightly to the polishing disc due to the pressure of the counterweight mechanism, ensuring the polishing disc achieves the desired grinding and polishing effect. Compared with traditional technologies, the glass clamp described above eliminates the need for workers to constantly press the glass sample against the polishing disc of the ring polisher, making the grinding and polishing process more labor-saving and effectively reducing the workload of workers.

[0011] In one embodiment, the loading member has a first end face and a second end face opposite each other along the axial direction of the mounting channel, the loading space is disposed through the first end face and the second end face, the loading space is used for the glass sample to pass through, and the counterweight mechanism presses against one of the first end face and the second end face.

[0012] In one embodiment, the first end face is provided with a first assembly part, the second end face is provided with a second assembly part, and the counterweight mechanism is provided with a mating part, which is assembled with one of the first assembly part and the second assembly part.

[0013] In one embodiment, the first assembly portion is provided with a first assembly groove, the second assembly portion is provided with a second assembly groove, and the mating portion is provided with a mating protrusion, the mating protrusion being engaged with one of the first assembly groove and the second assembly groove; or / and

[0014] The first assembly part is provided with a first assembly protrusion, the second assembly part is provided with a second assembly protrusion, and the mating part is provided with a mating groove, which is engaged with one of the first assembly protrusion and the second assembly protrusion.

[0016] In one embodiment, the first gasket is provided with at least two spaced circumferentially along the third end face; or / and,

[0017] The second gasket has at least two pieces and is spaced apart circumferentially along the fourth end face.

[0018] In one embodiment, the counterweight mechanism includes a counterweight base and counterweight members. The counterweight base has opposing fifth and sixth end faces. The fifth end face presses against the loading member. The counterweight members are provided in at least two and are stacked on the sixth end face.

[0019] In one embodiment, the counterweight mechanism further includes a pressing block disposed on the fifth end face, the pressing block pressing against the loading member.

[0020] In one embodiment, the counterweight mechanism further includes a mounting rod, one end of which is located on the sixth end face. The counterweight has a mounting through hole, and the mounting rod passes through the mounting through hole.

[0021] In one embodiment, at least two loading spaces are provided, and all the loading spaces are arranged at intervals in a horizontal plane intersecting the axial direction of the mounting channel. Attached Figure Description

[0036] Please see Figures 1 to 5 One embodiment of this application provides a glass clamp, including a mounting base 100, a loading member 200, and a counterweight mechanism 300. The mounting base 100 has a through mounting channel 110; the loading member 200 has a loading space 210 for accommodating a glass sample 400, the loading member 200 is located in the mounting channel 110 and can reciprocate along the axial direction of the mounting channel 110, so that the loading member 200 can drive the glass sample 400 to contact or move away from the polishing disc; the counterweight mechanism 300 is located on the side of the mounting base 100 away from the polishing disc and presses against the loading member 200, so that the loading member 200 has a tendency to move toward the polishing disc.

[0037] In use, the glass sample 400 is placed in the loading space 210 of the loading component 200. Under the pressure of the counterweight mechanism 300, the loading component 200 moves along the axis of the mounting channel 110 of the mounting base 100 and gradually approaches the polishing disc, thereby moving the glass sample 400 to contact the polishing disc. During the grinding and polishing process of the polishing disc, the glass sample 400 is tightly attached to the polishing disc due to the pressure of the counterweight mechanism 300, thus ensuring the grinding and polishing effect of the polishing disc on the glass sample 400. Compared with traditional technology, the glass clamp does not require the operator to press the glass sample 400 against the polishing disc of the ring polisher at all times, making the grinding and polishing process of the glass sample 400 more labor-saving and effectively reducing the labor intensity of the operator.

[0038] As an explanation, the counterweight mechanism 300 is located on the side of the mounting base 100 away from the ground. The glass sample 400 moves with the loading component 200 within the mounting channel 110 of the mounting base 100. Under the gravity of the counterweight mechanism 300, the loading component 200 drives the glass sample 400 to move toward the polishing disc, so that the glass sample 400 fits tightly against the polishing disc.

[0039] Optionally, the mounting base 100 can be set at the clamping station of the ring polisher, or it can be held by the operator; no specific limitation is made here. The polishing disc of the ring polisher can grind and polish the glass sample 400 to ensure the surface quality of the glass sample 400.

[0040] Furthermore, in one embodiment, the mounting base 100 is a cylindrical structure. As the main shaft of the ring polisher drives the disc to rotate, the rollers on the clamp of the ring polisher can rotate, thereby driving the glass sample 400 on the loading component 200 to rotate together, thereby grinding and polishing the glass sample 400.

[0041] In one embodiment, the loading component 200 is made of aluminum, which is strong and lightweight.

[0042] Please see Figure 4 and Figure 5 In one embodiment, the loading member 200 has a first end face 220 and a second end face 230 opposite each other along the axial direction of the mounting channel 110, and a loading space 210 is provided through the first end face 220 and the second end face 230. The loading space 210 is used for the glass sample 400 to pass through, and the counterweight mechanism 300 presses against one of the first end face 220 and the second end face 230.

[0043] The loading space 210 of the loading component 200 extends through the first end face 220 and the second end face 230. When the glass sample 400 is inserted into the loading space 210, the opposite ends of the glass sample 400 will protrude from the first end face 220 and the second end face 230, respectively. Thus, when grinding and polishing are required on the end of the glass sample 400 that protrudes from the first end face 220, the counterweight mechanism 300 is pressed against the second end face 230. The first end face 220 faces the polishing disc. Under the pressure of the counterweight mechanism 300, the first end face 220 tends to move towards the polishing disc, thereby causing the glass sample 400 to protrude from the first end face. One end of 220 can be tightly attached to the polishing disc; after the glass sample 400 protruding from the first end face 220 has been ground and polished, the loading component 200 is flipped so that the second end face 230 faces the polishing disc, and the counterweight mechanism 300 is pressed against the first end face 220. Under the pressure of the counterweight mechanism 300, the second end face 230 tends to move towards the polishing disc, so that the end of the glass sample 400 protruding from the second end face 230 can be tightly attached to the polishing disc to achieve grinding and polishing; with this setting, both ends of the glass sample 400 can be ground and polished, which is simple to operate and has low implementation cost.

[0044] It is understandable that when it is necessary to flip the loading component 200, the loading component 200 can be taken out from the installation channel 110, flipped, and then installed into the installation channel 110. Alternatively, the mounting base 100 and the loading component 200 can be flipped together as a whole. No specific limitation is made here.

[0045] Furthermore, before grinding and polishing the glass sample 400, it is necessary to cut and grind the glass sample 400 on all six sides to make the shape of the glass sample 400 more regular, so as to ensure that the glass sample 400 can be stably placed in the loading space 210.

[0046] Furthermore, in one embodiment, the glass sample 400 is columnar. The opposite ends of the columnar glass sample 400 can protrude from the first end face 220 and the second end face 230, respectively, to facilitate grinding and polishing of both sides of the glass sample 400.

[0047] In one embodiment, the loading space 210 is a channel-type structure, and the cross-sectional area of ​​the channel-type loading space 210 needs to be slightly larger than the cross-sectional area of ​​the sample glass to ensure that the sample glass can enter the loading space 210.

[0048] Please see Figures 2 to 5In one embodiment, the first end face 220 is provided with a first assembly part 221, the second end face 230 is provided with a second assembly part 231, and the counterweight mechanism 300 is provided with a mating part 310, which is assembled with one of the first assembly part 221 and the second assembly part 231.

[0049] The mating part 310 on the counterweight mechanism 300 can be assembled with one of the first assembly part 221 and the second assembly part 231 to press against the first end face 220 or the second end face 230, preventing the counterweight mechanism 300 and the loading part 200 from separating during the grinding and polishing of the glass sample 400.

[0050] Optionally, the assembly method between the mating part 310 and the first assembly part 221 can be snap-fit, adhesive, screw-fit, etc. Similarly, the assembly method between the mating part 310 and the second assembly part 231 can also be snap-fit, adhesive, screw-fit, etc., without specific limitations here.

[0051] Please see Figure 5 In one embodiment, at least two mating parts 310 are provided, and all mating parts 310 are arranged at intervals in a horizontal plane intersecting the axial direction of the mounting channel 110. At least two first assembly parts 221 are provided and correspond one-to-one with the mating parts 310, and at least two second assembly parts 231 are provided and correspond one-to-one with the mating parts 310.

[0052] Please see Figures 4 to 5 In one embodiment, the first assembly part 221 is provided with a first assembly groove 222, the second assembly part 231 is provided with a second assembly groove 232, and the mating part 310 is provided with a mating protrusion 311, which is engaged with one of the first assembly groove 222 and the second assembly groove 232.

[0053] When the counterweight mechanism 300 needs to be assembled with the first end face 220, the mating protrusion 311 will be embedded into the first assembly groove 222. When the counterweight mechanism 300 needs to be assembled with the second end face 230, the mating protrusion 311 will be embedded into the second assembly groove 232. This configuration results in low implementation cost and reliable assembly effect.

[0054] As an embodiment that can be replaced or implemented simultaneously with the above embodiments, the first assembly part 221 is provided with a first assembly protrusion, the second assembly part 231 is provided with a second assembly protrusion, and the mating part 310 is provided with a mating groove, which is engaged with one of the first assembly protrusion and the second assembly protrusion.

[0055] When the counterweight mechanism 300 needs to be assembled with the first end face 220, the first assembly protrusion is embedded in the mating groove; when the counterweight mechanism 300 needs to be assembled with the second end face 230, the second assembly protrusion is embedded in the mating groove. This configuration results in low implementation cost and reliable assembly effect.

[0056] Please see Figures 1 to 2 In one embodiment, the mounting base 100 has a third end face 120 and a fourth end face 130 opposite each other along the axial direction of the mounting channel 110. The third end face 120 is provided with a first gasket 121, and the fourth end face 130 is provided with a second gasket 131.

[0057] The first gasket 121 can prevent the third end face 120 from contacting the polishing disc and causing scratches to the polishing disc, and the second gasket 131 can prevent the fourth end face 130 from contacting the polishing disc and causing scratches to the polishing disc, so as to play a certain protective role for the polishing disc and ensure the grinding and polishing effect of the polishing disc on the glass sample 400.

[0058] As an explanation, since the mounting base 100 is usually made of a metal material with high hardness (such as aluminum), if the first end face 220 or the second end face 230 of the mounting base 100 comes into contact with the grinding and polishing disc during the grinding and polishing process of the glass sample 400, the surface accuracy of the grinding and polishing disc will decrease. By setting the first shim 121 and the second shim 131, the first end face 220 or the second end face 230 of the mounting base 100 can be prevented from directly contacting the grinding and polishing disc, thus preventing scratches on the grinding and polishing disc.

[0059] As further explained, one of the third end face 120 and the fourth end face 130 is positioned towards the counterweight mechanism 300, and the other is positioned towards the polishing disc. The positions of the third end face 120 and the fourth end face 130 can be changed by flipping the mounting base 100, thereby changing the end face to be processed of the glass sample 400. This will not be elaborated further here.

[0060] Furthermore, both the first gasket 121 and the second gasket 131 are made of glass. In this way, the hardness of the first gasket 121 and the second gasket 131 is similar to that of the glass sample 400, so they will not scratch the polishing disc.

[0061] Please see Figure 1 In one embodiment, the first gasket 121 is provided with at least two gaskets that are circumferentially spaced along the third end face 120.

[0062] At least two first gaskets 121 can provide further protection for the third end face 120.

[0063] Please see Figure 2 As an embodiment that can be replaced or implemented simultaneously with the above embodiments, the second gasket 131 is provided with at least two gaskets spaced circumferentially along the fourth end face 130. Similar to the above embodiments, it will not be described again here.

[0064] Please see Figures 3 to 5In one embodiment, the counterweight mechanism 300 includes a counterweight base 330 and a counterweight member 340. The counterweight base 330 has a fifth end face 331 and a sixth end face 332 opposite to each other. The fifth end face 331 presses against the loading member 200. The counterweight member 340 is provided with at least two and is stacked on the sixth end face 332.

[0065] The weight of the counterweight 340 stacked on the sixth end face 332 can be transmitted to the loading member 200 through the fifth end face 331 to press against the loading member 200, ensuring that the glass sample 400 on the loading member 200 can be tightly attached to the grinding and polishing disc, thus ensuring the grinding and polishing effect of the glass sample 400.

[0066] Furthermore, the staff can adjust the pressure of the counterweight mechanism 300 on the loading component 200 by adjusting the number of counterweights 340 located on the sixth end face 332, thereby adjusting the pressure of the glass sample 400 on the grinding and polishing disc and improving the grinding and polishing effect of the glass sample 400.

[0067] In one embodiment, the counterweight 330 is made of 45 steel.

[0068] In one embodiment, the counterweight 340 includes a counterweight disk, with at least two counterweight disks stacked on the sixth end face 332.

[0069] Please see Figure 5 In one embodiment, the counterweight mechanism 300 further includes a pressing block 320, which is disposed on the fifth end face 331 and presses against the loading member 200.

[0070] The pressure block 320 can effectively transfer the gravity of the counterweight mechanism 300 to the loading component 200, ensuring the grinding and polishing effect of the grinding and polishing disc on the glass sample 400.

[0071] Furthermore, at least two pressing blocks 320 are provided, and all pressing blocks 320 are arranged at intervals in a horizontal plane intersecting the axial direction of the mounting channel 110.

[0072] Please see Figures 3 to 5 In one embodiment, the counterweight mechanism 300 further includes a mounting rod 350, one end of which is located on the sixth end face 332. The counterweight 340 has a mounting through hole 341, through which the mounting rod 350 passes.

[0073] The mounting rod 350 located on the sixth end face 332 can pass through the mounting through hole 341 on the counterweight 340 to place the counterweight 340 on the sixth end face 332, which is low in cost and simple in operation.

[0074] Please see Figures 4 to 5In one embodiment, at least two loading spaces 210 are provided, and all loading spaces 210 are arranged at intervals in a horizontal plane intersecting the axial direction of the mounting channel 110.

[0075] By providing at least two loading spaces 210 on the loading member 200, the glass jig can simultaneously load at least two glass samples 400, enabling the glass jig to simultaneously grind and polish at least two glass samples 400, thereby improving the grinding and polishing efficiency of the glass samples 400.

[0076] Optionally, please refer to Figure 4 The loading space 210 on the loading component 200 can be a loading channel 211 that passes through the first end face 220 and the second end face 230, or it can be a loading groove 212 opened on the outer wall of the loading component 200. No specific limitation is made here.

[0077] Further, please refer to Figure 4 When the loading component 200 is placed in the mounting channel 110 of the mounting base 100, the groove wall of the loading groove 212 and the inner wall of the mounting channel 110 form a channel surrounding the outer periphery of the glass sample 400 to ensure the reliability of the loading of the glass sample 400 on the loading component 200.

[0078] Please see Figure 4 In one embodiment, the loading space 210 is shaped like a polygon, and correspondingly, the glass sample 400 is also shaped like a polygon that matches the loading space 210; this arrangement can prevent the glass sample 400 from rotating within the loading space 210, ensuring the reliability of the loading of the glass sample 400 by the loading member 200.

[0079] Specifically Figure 4 In the embodiment shown, the loading space 210 is cuboid in shape, and correspondingly, the glass sample 400 is also cuboid in shape that matches the loading space 210, which will not be described in detail here.

[0080] The following describes how to use the glass clamps in the above embodiments:

[0081] The first gasket 121 and the second gasket 131 are respectively bonded to the third end face 120 and the fourth end face 130 of the mounting base 100. The glass clamp is placed in hot water at 70°C to 80°C for preheating. After preheating, the moisture in the mounting channel 110 and the loading space 210 is dried. The cut glass sample 400 is shaped on all six sides and preheated to about 50°C. Then, adhesive is applied to the side of the glass sample 400. The glass sample 400 with adhesive is placed in the loading space 210 and the glass sample 400 with adhesive is pressed firmly against the inner wall of the loading space 210, so that the two ends of the glass sample 400 protrude from the first end face 220 and the second end face 230 by approximately the same length.

[0082] After the glass sample 400 and the loading component 200 are firmly bonded together, the mounting base 100 is installed in the clamping position of the ring polisher, and the loading component 200 is then inserted into the mounting channel 110. The counterweight base 330 is placed on the side of the loading component 200 away from the polishing disc of the ring polisher. According to the size, quantity and grinding amount of the glass sample 400, the counterweight 340 is set on the mounting rod 350. Then, the two ends of the glass sample 400 are coarsely ground and finely ground with diamond abrasive of different grits (during the grinding process, the height of the glass sample 400 needs to be measured at regular intervals to ensure that the dimensional accuracy of the final glass sample 400 meets the test requirements) until the surface roughness of the two ends of the glass sample 400 meets the requirements before polishing.

[0083] After fine grinding, the mounting base 100 and the loading component 200 with the glass sample 400 bonded to it are cleaned to remove the diamond grit from their surfaces. Then, the loading component 200 with the glass sample 400 and the mounting base 100 are placed on the polishing disc (polyurethane polishing mold) of the ring polisher, and the surfaces of both ends of the glass sample 400 are polished in turn (a certain number of counterweights 340 are set on the mounting rod 350 according to the size of the glass sample 400 and the amount of polishing removal).

[0084] After polishing, the loading part 200 with the glass sample 400 is cleaned to remove residual polishing powder. The inspectors test the smoothness and defects of the polished surface of the glass sample 400. After the test accuracy is reached, the loading part 200 with the glass sample 400 is placed in hot water at 70℃ to 80℃ to remove the adhesive and lower the plate. Finally, the glass is wiped clean and sent for testing.

[0085] Using the fixture in this application, the original manual rough grinding, fine grinding, and polishing processes can all be processed by equipment. The staff only needs to clamp, start the equipment, and add auxiliary materials for some processes. There is no need for the staff to press the sample on the grinding and polishing plate for a long time, which greatly reduces the labor intensity of the staff. At the same time, the processing time can be shortened from the original 4 hours to within 3 hours, which improves the processing efficiency by about 25%.

[0086] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0087] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
