Description

Technical Field

[0001] This utility model relates to the field of quartz processing and manufacturing technology, specifically to a quartz sheet chamfering device. Background Technology

[0002] Quartz has a very low coefficient of thermal expansion, resulting in minimal dimensional change with temperature variations. This gives it excellent resistance to thermal shock, allowing it to withstand rapid temperature changes without easily breaking. Its Mohs hardness is approximately 7, classifying it as a relatively hard material, making it scratch- and wear-resistant. Its high melting point allows it to maintain its physical properties and structural stability over a wide temperature range. Combined with its piezoelectric effect, it is widely used in hemispherical resonator gyroscopes, for example, in machining hemispherical resonators and creating spherical or planar electrodes to excite their vibration. To meet the clamping requirements before processing or the assembly requirements of the final product, chamfering is typically required on cylindrical quartz bodies or sheets. However, due to quartz's high hardness and brittleness, conventional cutting and grinding tools wear out quickly, leading to low processing efficiency. Furthermore, the quartz material itself is susceptible to impact or stress concentration during processing, resulting in defects such as cracks and chipping. Utility Model Content

It uses a grinding wheel to grind the quartz plate, resulting in a larger processing contact area compared to the grinding area of ​​a finished cutting tool, thus improving processing efficiency. Furthermore, a support feed mechanism is installed on the main frame, located below the mounting structure and close to the quartz plate. This support feed mechanism includes a feed drive cylinder and a limiting component. First, by tilting the mounting structure, before the quartz plate comes into contact with the grinding wheel, the piston rod of the drive cylinder extends to contact the mounting structure, supporting the tilted structure and preventing the risk of the hard, brittle quartz plate hitting the grinding wheel and damaging it due to free tilting of the mounting structure. When the piston rod of the drive cylinder slowly retracts, the mounting structure slowly tilts under gravity, allowing the quartz plate to... The edge of the quartz disc abuts against the grinding wheel. Due to the supporting force of the drive cylinder, the impact force is small when the edge of the quartz disc abuts against the grinding wheel, thus avoiding the risk of damage. As the piston rod continues to slowly retract, the edge of the quartz disc is ground by the grinding wheel to form a chamfer. During the chamfering process, the support force of the drive cylinder nozzle is controlled by adjusting the cylinder to counteract the impact force of the grinding wheel on the quartz disc, avoiding the risk of cracks, chipping, and other defects caused by impact or stress concentration during the chamfering process. The grinding wheel stops grinding the edge of the quartz disc when the mounting structure abuts against the limiting component. Thus, the chamfer size is controlled by the limiting component, and the drive cylinder, in conjunction with this, achieves a slow and uniform grinding feed during the chamfering process, thereby completing the chamfering of the quartz disc by the grinding wheel. This device has the advantages of compact structure and low cost, avoiding the problems associated with chamfering using conventional grinding tools and three-axis machining equipment. Furthermore, the feed speed and chamfer size are adjustable, and the processing contact area is large and the efficiency is high. Attached Figure Description

[0026] The embodiments of the present invention are described below with reference to the accompanying drawings, so that those skilled in the art can better understand and implement the present invention. However, the listed embodiments are not intended to limit the present invention. In the absence of conflict, the following embodiments and the technical features in the embodiments can be combined with each other, wherein the same components are indicated by the same reference numerals.

[0027] like Figures 1-8As shown, this embodiment provides a quartz wafer chamfering device, including: a main frame 5, a support and feed mechanism 6 disposed on the main frame 5, and a mounting structure 1 and a grinding wheel 8 rotatably mounted on the main frame 5. The grinding wheel 8 can rotate horizontally relative to the main frame 5, and the mounting structure 1 can rotate in a vertical plane relative to the main frame 5. Mounting structure 1 includes a mounting plate 12, a first motor 13 fixed to the mounting plate 12, and a mounting assembly. The mounting plate 12 is hinged to the main frame 5. The quartz plate 10 is fixed to the mounting assembly. The first motor 13 is connected to the mounting assembly for driving the quartz plate 10 to rotate axially via the mounting assembly. The support feed mechanism 6 is located below the mounting plate 12 and is located on the side of the mounting plate 12 near the hinge point of the quartz plate 10. The support feed mechanism 6 includes a feed drive cylinder 62 and a limiting member 61. The piston rod of the drive cylinder 62 extends to abut against the mounting plate 12 to support the inclined mounting structure 1. When the piston rod of the drive cylinder 62 retracts, the mounting structure 1 tilts under the action of gravity so that the edge of the quartz plate 10 abuts against the grinding wheel 8 and is ground by it to form a chamfer. When the mounting plate 12 abuts against the limiting member 61, the mounting structure 1 stops tilting so that the grinding wheel 8 stops grinding the edge of the quartz plate 10.

[0028] This utility model discloses a quartz plate chamfering device. It uses a grinding wheel to grind the quartz plate, resulting in a larger processing contact area compared to the grinding area of ​​a finished cutting tool, thus improving processing efficiency. Furthermore, a support feed mechanism is installed on the main frame, located below the mounting structure and close to the quartz plate. This support feed mechanism includes a feed drive cylinder and a limiting component. First, by tilting the mounting structure, before the quartz plate comes into contact with the grinding wheel, the piston rod of the drive cylinder extends to contact the mounting structure, supporting the tilted structure and preventing the risk of the hard, brittle quartz plate hitting the grinding wheel and damaging it due to free tilting of the mounting structure. When the piston rod of the drive cylinder slowly retracts, the mounting structure slowly tilts under gravity, allowing the quartz plate to... The edge of the quartz disc abuts against the grinding wheel. Due to the supporting force of the drive cylinder, the impact force is small when the edge of the quartz disc abuts against the grinding wheel, thus avoiding the risk of damage. As the piston rod continues to slowly retract, the edge of the quartz disc is ground by the grinding wheel to form a chamfer. During the chamfering process, the support force of the drive cylinder nozzle is controlled by adjusting the cylinder to counteract the impact force of the grinding wheel on the quartz disc, avoiding the risk of cracks, chipping, and other defects caused by impact or stress concentration during the chamfering process. The grinding wheel stops grinding the edge of the quartz disc when the mounting structure abuts against the limiting component. Thus, the chamfer size is controlled by the limiting component, and the drive cylinder, in conjunction with this, achieves a slow and uniform grinding feed during the chamfering process, thereby completing the chamfering of the quartz disc by the grinding wheel. This device has the advantages of compact structure and low cost, avoiding the problems associated with chamfering using conventional grinding tools and three-axis machining equipment. Furthermore, the feed speed and chamfer size are adjustable, and the processing contact area is large and the efficiency is high.

[0029] In this embodiment, the limiting member 61 is a stop screw or a micrometer.

[0030] In this embodiment, the mounting structure 1 also includes a slide table 11, which has a sliding groove. The mounting plate 12 is disposed in the sliding groove and can slide along the axial direction of the quartz plate. A detachable connection structure is provided between the slide table 11 and the mounting plate 12 to fix the two together.

[0031] By adjusting the relative position of the slide table 11 and the mounting plate, the distance between the mounting structure 1 and the grinding wheel disk 8 can be adjusted so that the quartz disc is positioned in a suitable position for the grinding wheel to be chamfered. After the position is adjusted, the two are fixed by fasteners.

[0032] In this embodiment, the mounting assembly includes a rotating shaft 23, a mounting sleeve 17, and a mounting base 18. The mounting sleeve 17 is fixed on the mounting plate 12. The rotating shaft 23 is sleeved on the mounting sleeve 17 and is rotatably connected to the mounting sleeve 17 in a sealed manner. Both ends of the rotating shaft 23 extend out of the mounting sleeve 17. One end is connected to the first motor 13 for transmission, and the other end is fixed to the mounting base 18. There is a vacuum channel between the rotating shaft 23, the mounting sleeve 17, and the mounting base 18. One end of the vacuum channel is connected to a vacuum pump. A quartz plate can seal the other end of the vacuum channel so that it can be adsorbed onto the mounting base 18 after the vacuum pump evacuates the vacuum channel.

[0033] The first motor 13 is fixed to the mounting plate 12 by the fixing bracket 14. The motor shaft of the first motor 13 is fixedly connected to one end of the rotating shaft 23 by a coupling 15. The side wall of the coupling 15 has an axial through groove and a circumferential 1 / 4 groove. The axial through groove communicates with its center hole, and the circumferential 1 / 4 groove communicates with the axial through groove. The purpose of the axial through groove is to increase the elasticity of the coupling and the magnitude of the tightening force. The circumferential 1 / 4 groove is to adjust the tightening effect when the two connecting shafts are not concentric. If the rotating shaft 23 is misaligned with the rotating shaft of the first motor 13, the tightening force of the screw can be increased or decreased by adjusting the part closer to the motor 13 (or the part closer to the rotating shaft 23).

[0034] In this embodiment, the rotating shaft 23 has an axially arranged central hole 232, the mounting sleeve 17 has a first air hole 171 on its side wall, the first air hole 171 is connected to the inner cavity 172 of the mounting sleeve 17, the rotating shaft 23 has a second air hole 231 on its side wall, the second air hole 231 is connected to the central hole 232 of the rotating shaft 23, and the mounting base 18 has an air passage connected to the central hole 232. The first air hole 171, the inner cavity 172 of the mounting sleeve 17, the second air hole 231, the central hole 232 of the rotating shaft 23 and the air passage of the mounting base 18 are connected to form an air extraction channel.

[0035] This device uses a vacuum channel designed into the mounting structure to connect with a vacuum pump, thereby employing negative pressure to adsorb quartz sheets or quartz pillars. This avoids the problems of scratches or roughness damage to the quartz surface caused by conventional clamps, and is especially suitable for quartz sheets with extremely high surface roughness, such as ultra-polished quartz sheets.

[0036] In this embodiment, the rotating shaft 23 and the mounting sleeve 17 are rotatably connected by a ball bearing 21. Oil seals are provided on both sides of the ball bearing 21 in the axial direction so that the rotating shaft 23 and the mounting sleeve 17 are rotatably connected in a sealed manner.

[0037] In this embodiment, the oil seal is located between the rotating shaft 23 and the mounting sleeve 17, and includes an outer oil seal 20 and an inner oil seal 22. The end of the rotating shaft 23 connected to the first motor 13 is also provided with an end cover 16, and the outer oil seal 20 at this end is located between the end cover 16 and the mounting sleeve 17.

[0038] In this embodiment, a slot is provided at one end of the mounting base 18 for fixing the rotating shaft 23. One end of the mounting base 18 is locked in the slot and fixed to the rotating shaft 23 by a locking screw 24. An adsorption groove 181 is provided at the other end of the mounting base facing the quartz plate. The quartz plate can close the adsorption groove 181. A first air distribution channel 241 is provided on the locking screw 24. One end of the first air distribution channel 241 is connected to the central hole 232, and the other end is connected to the adsorption groove 181 through a second air distribution channel 182 provided on the mounting base 18. The first air distribution channel 241 provided on the locking screw 24, the second air distribution channel 182 provided on the mounting base 18, and the adsorption groove 181 are connected to form the air passage of the mounting base 18.

[0039] In this embodiment, the grinding wheel 8 is connected to a rotary drive mechanism 9, which drives the grinding wheel 8 to rotate horizontally in the circumferential direction.

[0040] In this embodiment, the rotary drive mechanism 9 includes a second motor 91, a belt drive mechanism 92, and a main shaft 93. The main shaft 93 is rotatably mounted on the main frame 5 via a drive bearing. The grinding wheel 8 is fixed to the upper end of the main shaft 93. A secondary frame 7 is provided on one side of the main frame 5. The second motor 91 is fixed on the secondary frame 7. The main pulley of the belt drive mechanism 92 is connected to the second motor 91 for transmission. Its driven pulley is fixed on the main shaft 93, and its belt is tensioned between the main pulley and the driven pulley.

[0041] In this embodiment, the main frame 5 is provided with a support plate 51, the support plate 51 is provided with a support seat 4, the support seat 4 is equipped with a hinge seat 2 and a fixed seat 3, the slide table 11 is hingedly connected to the hinge seat 2, and the support feeding mechanism 6 is installed on the fixed seat 3.

[0042] In this embodiment, the hinge seat 2 includes a spindle 29 and a hinge sleeve 25. The spindle 29 and the hinge sleeve 25 are rotatably connected by a hinge bearing 27. The two ends of the spindle 29 extend out of the hinge sleeve 25 and are fixedly connected to the support seat 4. The slide 11 is fixedly connected to the hinge sleeve 25.

[0043] Specifically, dust covers 26 are fixed at both ends of the spindle 29, and the lower end of the dust cover 26 is fixedly connected to a fixing plate 28. The fixing plate 28 is detachably installed on the support base 4.

[0044] The installation steps for the chamfering device in this embodiment are as follows: Step 1: Fix the grinding wheel 8 onto the spindle 93 of the rotary drive mechanism 9; Step 2: Install and fix the hinge seat 2 on the support seat 4 via the fixing plate 28; the hinge sleeve 25 of the hinge seat 2 has a fixed mounting plane for supporting the fixed mounting structure 1; Step 3: Connect the support feeding mechanism 6 to the support base 4 via the fixed base 3; adjust the height of the limiting member 61 to be lower than the height of the support head of the drive cylinder 62; Step 4: Connect the main part of the mounting structure 1 without the quartz disc to the first motor 13 fixed on the mounting plate 12 via the open coupling 15. When tightening the open coupling 15 with screws, the axial opening of the open coupling 15 is to increase the elasticity of the coupling and the magnitude of the tightening force, while the circumferential 1 / 4 opening is to adjust the tightening effect when the connecting shafts at both ends are not concentric. If the rotating shaft 23 is misaligned with the rotating shaft of the first motor 13, the tightening force of the screws can be increased or decreased by adjusting the part closer to the first motor 13 (or the part closer to the rotating shaft 23). Step 5: Tighten the vented locking screw 24 to the rotating shaft 23, and connect the mounting base 18 to the threaded head of the locking screw 24 with the screw; wherein the locking screw 24 has 4 vent holes for negative pressure to diffuse to the 4 vent holes of the mounting base 18, and finally when the quartz plate 10 is installed into the mounting base 18, the negative pressure of the 4 holes will attract the quartz plate 10 to the mounting base 18; Step 6: The mounting sleeve 17 of the mounting structure 1 is connected to the mounting plate 12 by screws. The mounting plate 12 contacts the support head of the drive cylinder 62, preventing it from swinging downwards. Observe whether the end of the mounting structure 1 that fixes the quartz plate falls in the grinding wheel area suitable for grinding. By adjusting the relative position of the slide table 11 and the mounting plate 12, the mounting structure 1 is finally fixed. The steps for using the chamfering device in this embodiment are as follows: Step 1: Adjust the position of the installation structure 1 using the slide table 11 and mounting plate 12 to position the quartz disc in a suitable position for the grinding wheel to chamfer, and then tighten the slide table 11 and mounting plate 12. Step 2: Adjust the head height of the limiting member 61 and the drive cylinder 62 so that the head of the drive cylinder 62 is higher than the height of the limiting member 61, that is, at this time the mounting structure 1 is in contact with the head of the drive cylinder 62. Step 3: Connect the first air hole 171 to the vacuum equipment, and place the quartz plate 10 on the mounting base 18 so that the quartz plate 10 can be adsorbed on the mounting base 18 under negative pressure; start the first motor 13 to make the quartz plate 10 rotate under the drive of the first motor 13; simultaneously start the grinding wheel mechanism to rotate. Step 4: Start the drive cylinder 62, and slowly move the head of the drive cylinder 62 downward. Under the drive of the hinge seat 2, the mounting structure 1 moves slowly with the head of the drive cylinder 62 until the quartz plate 10 contacts the grinding wheel and begins grinding; adjust the height of the limiting member 61 to obtain the required chamfer size; then slowly adjust the height of the limiting member 61 until the chamfer meets the final requirements.
