Description

Technical Field

[0001] The invention relates to the field of ultra-precision machining of fused quartz glass spherical shell thin-wall parts, and in particular to a high-rigidity machining auxiliary support device for a hemispherical resonator. Background Art

[0002] Hemispherical resonators are made of high-purity fused quartz and have a hemispherical, thin-walled shell with a central support rod. The diameter is typically 15mm-50mm, the wall thickness is 0.3mm-1.1mm, the surface accuracy is less than 0.5μm, and the surface roughness Ra is less than 0.025μm. An ideal hemispherical resonator should have a high quality factor, isotropic elastic material, and isotropic dissipation. However, due to machining errors and surface defects during the manufacturing process, hemispherical resonators exhibit inconsistencies in density, Young's modulus, and shell thickness, leading to losses in quality factor and standing wave symmetry, affecting key gyroscope performance indicators such as stability, repeatability, noise, and calibration factor. The machining accuracy of a hemispherical resonator is crucial to its performance. High-precision machining surface shape, positional accuracy, and surface quality are key to ensuring the gyroscope's high precision and stability. Therefore, ultra-precision machining techniques are required during the manufacturing process to ensure the hemispherical resonator achieves ideal performance. The special-shaped thin shell structure of the hemispherical resonator is highly hard and brittle, and requires high shape and position accuracy (submicron level) for the inner and outer spherical surfaces and the central support rod, making it very difficult to manufacture.

In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and features of different embodiments or examples without contradiction.

[0031] The following combination Figures 1 to 8 The specific structure and installation method of the high-rigidity processing auxiliary support device of the hemispherical resonator of the present invention are described.

[0032] like Figures 1 to 5 As shown, the high-rigidity machining auxiliary support device for a hemispherical resonator includes a support component 100 and a fixing component 200. The support component 100 includes a support ring 110, multiple support assemblies 120, and multiple connecting assemblies 130. The multiple support assemblies 120 are sequentially arranged along the circumference of the support ring 110 to form a hemispherical support structure to support the inner spherical surface of the hemispherical resonator. The multiple support assemblies 120 are hingedly connected to the multiple connecting assemblies 130 in a one-to-one correspondence, and the multiple connecting assemblies 130 are all hingedly connected to the support ring 110. The fixing component 200 is detachably connected to the support ring 110 and is used to fix the support component 100 to the central support rod 300 of the hemispherical resonator.

[0033] The high-rigidity auxiliary support device for processing a hemispherical resonator provided by the present invention forms a hemispherical support structure to support the inner sphere of the hemispherical resonator by arranging multiple support components 120 in sequence along the circumferential direction on the outer periphery of a support ring 110, thereby effectively solving the problem of insufficient rigidity of the hemispherical thin-walled shell structure during processing. Since the fixing component 200 is detachably connected to the support ring 110, the auxiliary support component can be quickly disassembled and assembled as needed during the processing of the hemispherical resonator, thereby improving processing efficiency. Moreover, the auxiliary support component can be reused for hemispherical resonator products of the same specification, thereby effectively reducing the cost of use.

[0034] In one embodiment of the present invention, Figure 4 As shown, a first gap 121 is provided between two adjacent support assemblies 120, and the first gap 121 extends from the vertex of the hemispherical support structure to the end surface of the hemispherical support structure. Providing the first gap prevents interference between the two adjacent support assemblies 120, thereby reducing the assembly precision requirements for the auxiliary support components. Preferably, the dimensions of each support assembly 120 are equal, and the width of the first gap 121 between the two adjacent support assemblies 120 is equal. Using the same arrangement, each support assembly 120 can be interchanged during installation without having to consider the position of each support assembly 120, thereby simplifying the assembly method of the auxiliary support components and improving assembly efficiency.

[0035] In one embodiment of the present invention, Figure 5 As shown, support assembly 120 includes a first support block 122 and a second support block 123. The thickness of first support block 122 and second support block 123 can be the same or different, depending on actual needs. The width of first support block 122 and the width of second support block 123 both gradually decrease as they approach the apex of the hemispherical support structure. The minimum width of first support block 122 is equal to or greater than the maximum width of second support block 123.

[0036] The first support blocks 122 of two adjacent support assemblies 120 have the same size, and the second support blocks 123 of two adjacent support assemblies 120 also have the same size. The second support blocks 123 are spaced apart from the first support blocks 122, and a third gap is formed between the second support blocks 123 and the first support blocks 122. The third gaps of all support assemblies 120 are connected to form an annular gap. The second support blocks 123 and the first support blocks 122 are both hinged to the connecting assembly 130. The provision of the third gap ensures that the second support blocks 123 and the first support blocks 122 do not interfere with each other, and ensures that the sides of the first support blocks 122 and the second support blocks 123 facing away from the connecting assembly 130 can better contact the inner spherical surface of the hemispherical resonator, so that the sides of the first support blocks 122 and the second support blocks 123 facing away from the connecting assembly 130 can better support the inner spherical surface of the hemispherical resonator.

[0037] In one embodiment of the present invention, Figure 5 As shown, the sides of the first and second support blocks 122, 123 facing away from the connection assembly 130 are both curved. Since the second support block 123 is closer to the apex of the hemispherical support structure, the curvature of the curved surface of the second support block 123 is greater than that of the curved surface of the first support block 122. The curved surfaces of the first and second support blocks 122 are both provided with grooves 124. The groove width and depth of two adjacent first support blocks 122 are the same, and the groove positions of two adjacent first support blocks 122 correspond one-to-one. Thus, the grooves 124 of multiple first support blocks 122 are connected to form a first annular groove. The groove width and depth of two adjacent second support blocks 123 are the same, and the groove positions of two adjacent second support blocks 123 correspond one-to-one. Thus, the grooves 124 of multiple second support blocks 123 are connected to form a second annular groove. The radius of the first annular groove 124 is greater than the radius of the second annular groove 124. The width of the first annular groove 124 can be the same as or different from the width of the second annular groove 124, depending on actual needs.

[0038] Since the first support block 122 and the second support block 123 are in contact with the inner sphere of the hemispherical resonator through their curved surfaces, in order to effectively support the inner sphere of the hemispherical resonator, it is necessary to ensure that the curved surfaces of the first support block 122 and the second support block 123 are completely in contact with the inner sphere of the hemispherical resonator. However, this also increases the machining accuracy requirements for the curved surfaces of the first support block 122 and the second support block 123, and also increases the production cost. By providing grooves 124 on the curved surfaces of the first support block 122 and the second support block 123, strip-shaped curved contact surfaces are formed on both sides of the grooves 124 to contact the inner sphere of the hemispherical resonator, thereby reducing the contact area between the first support block 122 and the second support block 123 and the inner sphere of the hemispherical resonator. Only the strip-shaped curved contact surfaces on both sides of the grooves 124 need to contact the inner sphere of the hemispherical resonator, which reduces the machining accuracy requirements to a certain extent.

[0039] At the same time, since the second support block 123 and the first support block 122 are both hinged to the connecting assembly 130, the second support block 123 and the first support block 122 can also rotate around the hinge point with the connecting assembly 130. When the strip-shaped arc contact surface on one side of the groove 124 contacts the inner spherical surface of the hemispherical resonator, under the pressure of the inner spherical surface of the hemispherical resonator, the second support block 123 and the first support block 122 can rotate around their respective hinge points, so that the strip-shaped arc contact surface on the other side of the groove 124 approaches the inner spherical surface of the hemispherical resonator and finally contacts the inner spherical surface of the hemispherical resonator. In this way, regardless of whether the second support block 123 and the first support block 122 are assembled in place, the arc surfaces of the second support block 123 and the first support block 122 can make good contact with the inner spherical surface of the hemispherical resonator, thereby reducing the assembly requirements for the second support block 123 and the first support block 122.

[0040] In one embodiment of the present invention, Figure 5 As shown, a first mounting groove is provided on the side of the first support block 122 facing the connecting assembly 130. The first mounting groove is located in the center area of ​​the side of the first support block 122 facing the connecting assembly 130. The first mounting groove is a square groove body, which can be easily processed. Of course, the shape of the first mounting groove is not limited to this and is determined according to actual needs. The provision of the first mounting groove has the following two advantages: on the one hand, it provides a mounting position for one end of the support push rod 131, and on the other hand, it allows one end of the support push rod 131 to enter the first mounting groove, reducing the total volume of the first support block 122 and the support push rod 131, improving the compactness of the auxiliary support component, and making the hemispherical surface of the support structure smaller, meeting the requirements of a smaller-sized hemispherical resonator.

[0041] A second mounting groove is provided on the side of the second support block 123 facing the connecting assembly 130. Similarly, the second mounting groove is located in the center area of ​​the side of the second support block 123 facing the connecting assembly 130. The second mounting groove is a square groove body, which is convenient for processing. Of course, the shape of the second mounting groove is not limited to this and is determined based on actual needs. The provision of the second mounting groove has the following two advantages: on the one hand, it provides a mounting position for the other end of the support push rod 131, and on the other hand, it allows the other end of the support push rod 131 to enter the second mounting groove, reducing the total volume of the second support block 123 and the support push rod 131, and improving the compactness of the auxiliary support component.

[0042] In one embodiment of the present invention, Figure 5 As shown, the connecting assembly 130 is used to connect the support ring 110 and multiple support assemblies 120. The number of connecting assemblies 130 is the same as the number of support assemblies 120. Multiple connecting assemblies 130 are arranged at intervals along the circumference of the support ring 110. The distance between two adjacent connecting assemblies 130 can be the same or different, which is specifically determined according to the size of the two adjacent support blocks.

[0043] The connecting assembly 130 includes a support push rod 131 and a support connecting rod 132. In this embodiment, the support push rod 131 is U-shaped. However, the shape of the support rod is not limited to this and may also be C-shaped, V-shaped, or other shapes. In this embodiment, the support push rod 131 has two connecting ends, each connected to a corresponding support block. Of course, the number of connecting ends of the support push rod 131 is not limited to this and is determined by the number of support blocks in the same group.

[0044] One end of the support push rod 131 is inserted into the first mounting slot and hingedly connected to the first support block 122 via a pin. The other end of the support push rod 131 is inserted into the second mounting slot and hingedly connected to the second support block 123 via a pin. Specifically, the first mounting slot has two opposing sidewalls each provided with a positioning hole. One end of the support push rod 131 has a through hole, through which the pin extends, with its ends correspondingly inserted into the two positioning holes. The second mounting slot has two opposing sidewalls each provided with a positioning hole. The other end of the support push rod 131 has a through hole, through which the pin extends, with its ends correspondingly inserted into the two positioning holes.

[0045] The support link 132 is used to connect the support push rod 131 and the support ring 110. One end of the support link 132 is connected to the support push rod 131, and the other end of the support link 132 is hinged to the support ring 110. Specifically, a connecting groove is provided in the middle of the support push rod 131. One end of the support link 132 is inserted into the connecting groove and is hinged to the support link 132 via a pin. The provision of the connecting groove can achieve a limited fit between the support link 132 and the support push rod 131 in the thickness direction of the support link 132.

[0046] In one embodiment of the present invention, Figure 5 As shown, the outer circumferential surface of the support ring 110 is provided with multiple groups of connecting ears, which are spaced apart along the circumference, and the distance between two adjacent groups of connecting ears 111 is equal. Each group of connecting ears includes two connecting ears, and the two connecting ears 111 are spaced apart. The connecting ears 111 are welded to the support ring 110 or integrally formed. The distance between the two connecting ears 111 is slightly greater than the thickness of the other end of the support link 132. The other ends of the multiple support links 132 are inserted between the two connecting ears 111 of the corresponding group and are hinged to the two connecting ears 111 via a pin. By providing two connecting ears 111 to fix the support link 132, the support link 132 can be limited in the thickness direction of the support link 132, preventing the support link 132 and the support block from swinging in the thickness direction of the support link 132.

[0047] In one embodiment of the present invention, Figures 6 to 8 As shown, the fixing component 200 includes a clamping sleeve 210, a clamping nut 220 and an auxiliary support sleeve 230. The clamping sleeve 210 includes a clamping sleeve body 211 and a clamping portion 212 connected to one end of the clamping sleeve body 211. The clamping sleeve body 211 and the clamping portion 212 are integrally formed. The thickness of the clamping sleeve body 211 is greater than the maximum thickness of the clamping portion 212 to form a step at the connection between the clamping sleeve body 211 and the clamping portion 212. The outer peripheral surface of the clamping sleeve body 211 is provided with a first external thread.

[0048] The clamping portion 212 is in the form of a truncated cone, and the clamping portion 212 is provided with a plurality of second slits 213 spaced apart along the circumferential direction. The distances between adjacent second slits 213 may be the same or different. The second slits 213 extend along the axial direction of the clamping portion 212 to divide the clamping portion 212 into a plurality of clamping pieces 214. The outer diameter of the clamping portion 212 gradually decreases in the direction away from the clamping sleeve body 211, so that the thickness of the clamping piece 214 gradually decreases in the direction away from the clamping sleeve body 211. When squeezed by the clamping nut 220, the end of the clamping piece 214 away from the clamping sleeve body 211 is more likely to be deformed.

[0049] The clamping nut 220 has a mounting hole inside. The clamping nut 220 is mounted on the outside of the clamping sleeve 210 through the mounting hole. One end of the mounting hole is provided with a first internal thread that mates with the first external thread. The inner diameter of one end of the mounting hole is fixed. The clamping nut 220 is mounted on the clamping sleeve 210, and the clamping sleeve 210 and the clamping nut 220 are threadedly engaged. The inner diameter of the other end of the mounting hole gradually decreases as it moves away from the first internal thread. Preferably, the maximum inner diameter of the other end of the mounting hole is smaller than the inner diameter of the one end of the mounting hole. Because the inner diameter of the other end of the mounting hole gradually decreases as it moves away from the first internal thread, when the clamping nut 220 is rotated, the deeper the clamping portion 212 enters the other end of the mounting hole, the greater the extent to which the clamping portion 212 is squeezed, and the smaller the width of the second gap 213 between two adjacent clamping pieces 214, thereby clamping the central support rod 300.

[0050] Preferably, the length of the second slit 213 is greater than the length of the clamping portion 212 , that is, the second slit 213 extends to the clamping sleeve body 211 .

[0051] The auxiliary support sleeve 230 has an annular structure and is sleeved over the outer circumference of the clamping nut 220. The auxiliary support sleeve 230 cooperates with the support ring 110 in an axially limited position, thereby securing the support ring 110 to the clamping nut 220 and preventing the support ring 110 from moving axially relative to the clamping nut 220. Preferably, the outer circumference of the other end of the clamping nut 220 is provided with a second external thread, and the inner wall of the auxiliary support sleeve 230 is provided with a second internal thread, and the second external thread is threadably engaged with the second internal thread.

[0052] In one embodiment of the present invention, a guide groove 231 is provided between the outer circumferential surface of one end of the clamping nut 220 and the inner wall of the support ring 110. A guide portion 221 is provided between the outer circumferential surface of the clamping nut 220 and the inner wall of the support ring 110. The guide portion 221 and the guide groove 231 provide axial guidance. Specifically, the guide portion 221 is a guide block that extends axially along the clamping nut 220 and is integrally formed with the clamping nut 220. Two guide blocks are provided, symmetrically disposed on the outer circumferential surface of the clamping nut 220. Two guide grooves 231 are provided on the inner wall of the support ring 110, and the width of the guide grooves 231 is slightly greater than the width of the guide blocks, so that the guide blocks can be slidably retained within the guide grooves 231, thereby achieving circumferentially limited engagement between the clamping nut 220 and the support ring 110.

[0053] Assembly method of high-rigidity machining auxiliary support device for hemispherical resonator: First, assemble the fixing component 200 , sleeve the clamping nut 220 onto the outside of the clamping sleeve 210 , and rotate the clamping nut 220 to ensure that the conical surface inside the clamping nut 220 fits with the conical surface outside the clamping sleeve 210 .

[0054] To assemble the support component 100, first install the first support block 122 and the second support block 123 at both ends of the support push rod 131. The support push rod 131 is connected to the first support block 122 and the second support block 123 via a pin. Then, connect one end of the support connecting rod 132 to the hole in the middle of the support push rod 131 via a pin. The support connecting rod 132 is also connected to the two connecting ears 111 on the outside of the support ring 110 via a pin. Then, install the remaining seven sets of support assemblies 120 and connecting assemblies 130 in the same manner along the circumference of the support ring 110, completing the assembly of the support component 100.

[0055] First, install the support component 100 on the outside of the fixing component 200 to ensure that the guide block of the clamping nut 220 is inserted into the corresponding guide groove 231 , and then install the auxiliary support sleeve 230 on the outside of the clamping nut 220 .

[0056] During the process of processing the outer sphere of the hemispherical resonator, the entire auxiliary support component is put on the central support rod 300 on the inner sphere side of the hemispherical resonator to initially ensure that the outer sphere of the auxiliary support component is in contact with the inner sphere of the hemispherical resonator, and then the clamping nut 220 of the auxiliary support component is tightened. Through the conical structure between the clamping nut 220 and the clamping sleeve 210, it is ensured that the fixing component 200 in the auxiliary support component can clamp the central support rod 300, thereby ensuring that the entire auxiliary support component can be fixed on the hemispherical resonator.

[0057] Then, the auxiliary support sleeve 230 in the auxiliary support component is rotated, and the auxiliary support sleeve 230 will squeeze the support ring 110 toward the inner spherical surface of the hemispherical resonator. Since a guide device is provided on the outer side of the clamping nut 220 and the inner side of the support ring 110, the clamping nut 220 can be prevented from causing the support component 100 to rotate when squeezing the support ring 110. The support ring 110 is connected to one end of 8 support links 132, and then the other end of each support link 132 is connected to the support push rod 131, and each support push rod 131 is connected to the first support block 122 and the second support block 123. Therefore, a support link 132, a support push rod 131, a first support block 122 and a second support block 123 form a unit. There are 8 identical support units evenly distributed on the circumference of the support ring 110, ensuring that when the support ring 110 is squeezed inward, each support unit can expand outward synchronously, ensuring that the outer sphere of the auxiliary support component is in close contact with the inner sphere of the hemispherical resonator, thereby increasing the rigidity of the hemispherical resonator during processing.
