Description

Technical Field

[0001] This application relates to the field of lathe machining technology, and in particular to a method, equipment and storage medium for machining a sealing groove. Background Technology

[0002] The main bearing is a key component of a tunneling machine, typically embedded within the main drive unit. Because it primarily bears the extremely large and complex alternating loads and overturning moments generated by varying geological conditions during tunneling, its operating condition and service life determine the overall performance and lifespan of the tunneling machine. Furthermore, its operating condition and service life are closely related to the bearing's sealing performance; the better the sealing, the better the operating condition and the longer the service life.

[0003] The sealing effect of the main bearing is mainly affected by the design of the sealing groove at the lubrication hole of the main bearing and the O-ring used. The existing sealing rings at the lubrication hole of the main bearing are usually finished O-rings that match the diameter of the lubrication hole. This requires the opening of a sealing groove around the lubrication hole to match the O-ring.

[0004] Because O-rings from different manufacturers or of different specifications vary in size and material, the corresponding sealing groove opening size for machining O-rings is often designed based on experience. However, experience-based design can easily lead to a mismatch between the sealing groove and the O-ring. When the two are not well matched, it will affect the sealing effect of the main bearing, thereby reducing the service life of the main bearing and the safety and reliability of the tunneling machine in engineering applications. Summary of the Invention

[0005] This application provides a method, equipment, and storage medium for processing sealing grooves, which addresses the issue that due to differences in the size and material of O-rings from different manufacturers or of different specifications, the opening size of the corresponding sealing groove is often designed based on experience. This experience-based design can easily lead to a mismatch between the sealing groove and the O-ring. When the mismatch is not high, it will affect the sealing effect of the main bearing, thereby reducing the service life of the main bearing and compromising the safety and reliability of the tunneling machine in engineering applications.

[0006] In a first aspect, this application provides a method for processing a sealing groove, including:

[0007] Obtain the specifications of the sealing ring, which include the inner diameter and the cross-sectional diameter of the sealing ring;

[0008] Based on the inner diameter of the sealing ring, the cross-sectional diameter of the sealing ring, and the preset inner diameter, preset width, and preset depth of the sealing groove, as well as the preset compression rate, preset elongation rate, and preset cross-sectional fill rate of the sealing ring, target parameters matching the sealing ring are determined; wherein, the target parameters include the inner diameter and depth of the sealing groove that simultaneously satisfy the preset compression rate, preset elongation rate, and preset cross-sectional fill rate ranges.

[0009] The target parameters are sent to the processing terminal so that the processing terminal can process the sealing groove according to the target parameters.

[0010] In one possible design, determining the target parameters matching the sealing ring based on the inner diameter of the sealing ring, the cross-sectional diameter of the sealing ring, and the preset inner diameter, preset width, and preset depth of the sealing groove, as well as the preset compression rate, preset elongation rate, and preset cross-sectional fill rate of the sealing ring, includes:

[0011] The initial compression ratio of the sealing ring is determined based on the diameter of the sealing ring section and the preset depth of the sealing groove.

[0012] If the initial compression ratio of the sealing ring is less than the preset compression ratio, the initial tensile ratio of the sealing ring is determined according to the inner diameter of the sealing ring and the preset inner diameter of the sealing groove.

[0013] If the initial elongation of the sealing ring is less than the preset elongation, the contact width of the sealing ring is determined according to the cross-sectional diameter of the sealing ring and the initial compression ratio.

[0014] If the contact width of the sealing ring is less than a preset ratio of the preset width of the sealing groove, the deformation width of the sealing ring is determined according to the initial compression ratio and the diameter of the sealing ring cross section.

[0015] If the deformation width of the sealing ring is less than the preset width of the sealing groove, the cross-sectional fill rate of the sealing ring is determined according to the preset depth of the sealing groove, the cross-sectional diameter of the sealing ring, and the preset width of the sealing groove.

[0016] If the cross-sectional fill rate of the sealing ring is not less than the preset fill rate threshold, then the preset depth of the sealing groove and the preset inner diameter of the sealing groove are used as target parameters that match the specifications of the sealing ring.

[0017] One possible design also includes:

[0018] If the initial compression ratio of the sealing ring is not less than the preset compression ratio, the preset depth of the sealing groove is increased by a preset unit amount until the compression ratio of the sealing ring is less than the preset compression ratio, thus obtaining the first depth of the sealing groove.

[0019] Based on the first depth of the sealing groove, the diameter of the sealing ring section, and the preset width of the sealing groove, the contact width, deformation width, and cross-sectional filling rate of the sealing ring corresponding to the first depth are determined. When the contact width, deformation width, and cross-sectional filling rate of the sealing ring all meet the preset compression rate, preset tensile rate, and preset cross-sectional filling rate, the first depth of the sealing groove and the preset inner diameter of the sealing groove are used as target parameters that match the specifications of the sealing ring.

[0020] One possible design also includes:

[0021] If the contact width of the sealing ring is not less than a preset proportion of the preset width of the sealing groove, then the first depth of the sealing groove is increased by a preset unit amount until the contact width of the sealing ring is less than a preset proportion of the preset width of the sealing groove, thus obtaining the second depth of the sealing groove.

[0022] Based on the second depth of the sealing groove, the diameter of the sealing ring section, and the preset width of the sealing groove, the contact width, deformation width, and cross-sectional filling rate of the sealing ring corresponding to the second depth are determined. When the contact width, deformation width, and cross-sectional filling rate of the sealing ring all meet the preset compression rate, preset tensile rate, and preset cross-sectional filling rate, the second depth of the sealing groove and the preset inner diameter of the sealing groove are taken as target parameters that match the specifications of the sealing ring.

[0023] One possible design also includes:

[0024] If the deformation width of the sealing ring is not less than the preset width of the sealing groove, the second depth is reduced by a preset unit amount until the deformation width of the sealing ring is less than the preset width of the sealing groove, thus obtaining the third depth of the sealing groove.

[0025] Based on the third depth of the sealing groove, the diameter of the sealing ring section, and the preset width of the sealing groove, the contact width, deformation width, and cross-sectional fill rate of the sealing ring corresponding to the third depth are determined. When the contact width, deformation width, and cross-sectional fill rate of the sealing ring all meet the preset compression rate, preset tensile rate, and preset cross-sectional fill rate, the third depth of the sealing groove and the preset inner diameter of the sealing groove are taken as target parameters that match the specifications of the sealing ring.

[0026] One possible design also includes:

[0027] If the initial stretching ratio of the sealing ring is not less than the preset stretching ratio, then the preset inner diameter of the sealing groove is reduced by a preset unit amount until the stretching ratio of the sealing ring is less than the preset stretching ratio, thus obtaining the first inner diameter of the sealing groove.

[0028] Replace the preset inner diameter of the sealing groove with the first inner diameter of the sealing groove as the target parameter that matches the specifications of the sealing ring.

[0029] Secondly, this application provides a sealing groove processing device, comprising:

[0030] The acquisition module is used to acquire the specifications of the sealing ring, which include the inner diameter and the cross-sectional diameter of the sealing ring.

[0031] The processing module is used to determine target parameters that match the sealing ring based on the inner diameter of the sealing ring, the cross-sectional diameter of the sealing ring, the preset inner diameter, preset width, preset depth of the sealing groove, the preset compression rate, preset elongation rate, and preset cross-sectional filling rate of the sealing ring; wherein, the target parameters include the inner diameter and depth of the sealing groove that simultaneously meet the preset compression rate, preset elongation rate, and preset cross-sectional filling rate ranges.

[0032] The sending module is used to send the target parameters to the processing terminal so that the processing terminal can process the sealing groove according to the target parameters.

[0033] Thirdly, this application provides an electronic device, including: a processor, and a memory communicatively connected to the processor;

[0034] The memory stores computer-executed instructions;

[0035] The processor executes computer execution instructions stored in the memory to implement the sealing groove processing method.

[0036] Fourthly, this application provides a computer-readable storage medium storing computer-executable instructions, which, when executed by a processor, are used to implement a sealing groove processing method.

[0037] Fifthly, this application provides a computer program product, including a computer program that, when executed by a processor, implements a sealing groove processing method.

[0038] The sealing groove processing method, equipment, and storage medium provided in this application obtain the specifications of the sealing ring, including its inner diameter and cross-sectional diameter. Based on the inner diameter and cross-sectional diameter of the sealing ring, as well as the preset inner diameter, preset width, preset depth, preset compression rate, preset tensile rate, and preset cross-sectional filling rate of the sealing groove, target parameters matching the sealing ring are determined. These target parameters are then sent to the processing terminal, enabling the processing terminal to process the sealing groove according to these parameters. Compared to the prior art where the opening size of the sealing groove corresponding to O-ring processing is often designed empirically, which can easily lead to a low matching degree between the sealing groove and the O-ring, a low matching degree can affect the sealing effect of the main bearing, thereby reducing the service life of the main bearing and compromising the safety and reliability of the tunneling machine in engineering applications, this application achieves an automated calculation function for the size of the sealing groove to be processed, improving the accuracy of the fit between the sealing groove and the sealing ring, thereby improving the sealing performance of the main bearing and extending the service life of both the main bearing and the sealing ring.

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0047] Different geological environments determine the complex stress and contaminant conditions faced by tunneling machines during tunneling operations. Improper design of the oil hole sealing groove and seal size in the main bearing can affect the structural strength of the main bearing, allow contaminants to enter the main bearing or main drive, and impair the lubrication and sealing performance of the main bearing or main drive. Therefore, the design of the oil hole sealing groove and seal size in the main bearing directly affects the lubrication and sealing performance of the main bearing, thus directly influencing its operating condition and determining the overall lifespan of the tunneling machine.

[0048] Currently, there is no established design methodology for the sealing groove and O-ring used in the lubrication oil hole of tunneling machine main bearings. This is a critical weakness easily overlooked in main bearing design. The design of the sealing groove and O-ring often relies on experience, lacking methodological guidance and theoretical support. Such experience-based design carries significant design risks. Therefore, there is an urgent need for a design methodology suitable for matching the sealing groove and seal size to the lubrication oil hole of tunneling machine main bearings. This methodology would provide guidance and theoretical support for the design of the sealing groove and seal size selection at the lubrication oil hole of tunneling machine main bearings, thereby ensuring the lubrication and sealing function of the main bearing, improving its service life, and enhancing the safety and reliability of the tunneling machine in engineering applications.

[0049] The sealing groove processing method provided in this application is based on the following technical concept: for different specifications of existing standard sealing rings, the dimensions of the sealing groove to be processed that meet the preset compression rate, preset elongation rate and preset cross-sectional filling rate of the sealing ring are calculated respectively. Without affecting the area occupied by the sealing groove by the equipment itself, the inner diameter and depth of the sealing groove are finely adjusted to meet the specifications of existing sealing rings, aiming to solve the above-mentioned technical problems of the prior art.

[0050] The specific application scenarios for this application are as follows:

[0051] Figure 1 This is a schematic diagram illustrating an application scenario of the sealing groove processing method provided in the embodiments of this application. For example... Figure 1As shown, a sealing groove is provided around the lubrication hole 102 of the main bearing 101. To avoid affecting the dimensions of other components or the main bearing itself, the outer diameter 103 of the sealing groove is usually fixed. That is, within the outer diameter 103, the sealing groove can be adapted to different sizes of sealing rings by adjusting its depth and width. During the adjustment process, due to the presence of the lubrication hole 102, the width has an adjustable range, meaning the inner diameter 104 of the sealing groove has a minimum value. Therefore, the width can only be reduced by increasing the inner diameter 104, thus finding the sealing groove size suitable for the sealing ring. If the sealing ring's requirements cannot be met by adjusting the depth and width, a sealing ring of another size needs to be replaced, and the above adjustment steps repeated to obtain a suitable size.

[0052] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0053] Figure 2 A schematic flowchart of the sealing groove processing method provided in the embodiments of this application. Figure 1 .like Figure 2 As shown, the method includes:

[0054] S201. Obtain the specifications of the sealing ring, which include the inner diameter and cross-sectional diameter of the sealing ring.

[0055] Specifically, the sealing ring is an existing standard part, and its size, material and other parameters are fixed. Therefore, when processing the sealing groove, it is necessary to take into account the specific specifications of the sealing ring and adjust the size of the sealing groove according to the standard that the specifications of the sealing ring can be used.

[0056] Since the sealing ring needs to undergo a certain amount of tension and compression, that is, to make a certain contact with the sealing groove in order to achieve a sealing effect, the inner diameter of the sealing ring and the cross-sectional diameter of the sealing ring are two key parameters used in the machining of the sealing groove.

[0057] S202. Based on the inner diameter of the sealing ring, the cross-sectional diameter of the sealing ring, the preset inner diameter, preset width, preset depth of the sealing groove, the preset compression rate, preset elongation rate, and preset cross-sectional filling rate of the sealing ring, determine the target parameters that match the sealing ring.

[0058] The target parameters include the inner diameter and depth of the sealing groove that simultaneously meet the preset compression rate, preset elongation rate, and preset cross-sectional fill rate ranges.

[0059] Specifically, the preset inner diameter, preset width, and preset depth of the sealing groove are parameters that are predetermined based on experience, and can also be set arbitrarily. Experience can only reduce the amount of calculation required for adjustment, but cannot guarantee the matching degree between the sealing ring and the sealing groove.

[0060] Based on the cross-sectional diameter of the sealing ring and the preset depth of the sealing groove, the compression ratio of the sealing ring can be calculated. Based on the inner diameter of the sealing ring and the preset inner diameter of the sealing groove, the elongation ratio of the sealing ring can be calculated. By comparing the compression ratio and elongation ratio with the preset compression ratio and preset elongation ratio, it can be determined whether the preset depth and preset inner diameter meet the usage requirements of the sealing ring. If they do not meet the requirements, the preset depth and preset inner diameter need to be adjusted. If no adjustment is needed, the cross-sectional fill rate is calculated based on the preset depth and preset width of the sealing groove and the cross-sectional diameter of the sealing ring, and compared with the preset cross-sectional fill rate. If the requirements are met, the preset inner diameter, preset width, and preset depth of the sealing groove can be used directly as the target parameters for the sealing ring. If the requirements are not met, the specifications of the sealing ring need to be changed.

[0061] During adjustment, the compression ratio can be reduced by increasing the depth, the elongation ratio can be reduced by decreasing the preset inner diameter, and the compression ratio can be adjusted by increasing the depth, thereby adjusting the contact width between the sealing ring and the sealing groove before and after deformation. Then, based on the adjusted depth, preset width, and sealing ring cross-sectional diameter, a suitable cross-sectional filling rate can be obtained to ensure the sealing degree.

[0062] S203. Send the target parameters to the processing terminal so that the processing terminal can process the sealing groove according to the target parameters.

[0063] Specifically, the processing terminal can receive target parameters corresponding to one sealing ring or multiple sealing rings respectively. The processing terminal can determine the target parameters based on the secondary confirmed sealing ring specifications, and then perform fine processing on the sealing groove according to the target parameters, thereby improving the sealing performance of the main bearing.

[0064] The method provided in this embodiment obtains the specifications of the sealing ring, including its inner diameter and cross-sectional diameter. Based on the inner diameter and cross-sectional diameter of the sealing ring, as well as the preset inner diameter, preset width, preset depth, preset compression rate, preset elongation rate, and preset cross-sectional filling rate of the sealing groove, target parameters matching the sealing ring are determined. These target parameters are then sent to a processing terminal, enabling the processing terminal to process the sealing groove according to these target parameters. This method automates the calculation of the dimensions of the sealing groove to be processed, improves the accuracy of the fit between the sealing groove and the sealing ring, thereby enhancing the sealing performance of the main bearing and extending the service life of both the main bearing and the sealing ring.

[0065] The sealing groove processing method of this application will be described in detail below with reference to a specific embodiment.

[0066] Figure 3 A schematic flowchart of the sealing groove processing method provided in the embodiments of this application. Figure 2 ; Figure 6 This is a schematic diagram illustrating the contact state between the sealing groove and the sealing ring provided in an embodiment of this application. Figure 3 As shown, the method includes:

[0067] S301. Obtain the specifications of the sealing ring, which include the inner diameter and cross-sectional diameter of the sealing ring.

[0068] The specific implementation of S301 is similar to that of S201, and will not be described again in this embodiment.

[0069] S302. Determine the initial compression ratio of the sealing ring based on the cross-sectional diameter of the sealing ring and the preset depth of the sealing groove.

[0070] like Figure 1 As shown, m1 is the minimum distance from the sealing groove on one side to the edge of the collar, m2 is the minimum distance from the sealing groove on the other side to the edge of the collar, n1 is the minimum distance from the sealing groove on one side to the lubricating oil hole, m2 is the minimum distance from the sealing groove on the other side to the lubricating oil hole, b is the width of the sealing groove cross section, and h is the depth between the bottom of the sealing groove and the sealed surface.

[0071] The shortest distance between the sealing groove and the lubricating oil hole and the edge of the ring should be greater than 4mm to ensure the structural strength of the ring. That is, n1, m1, n2, and m2 are all ≥4mm. Preferably, the inner diameter of the sealing groove can be set according to the minimum distance n1 or n2 between the lubricating oil hole and the inner diameter of the sealing groove. The value of n1 or n2 is in the range of 5mm to 8mm.

[0072] Specifically, based on the diameter d2 of the sealing ring section and the preset depth h0 of the sealing groove, the following formula is used:

[0073]

[0074] Determine the initial compression ratio A0 of the sealing ring.

[0075] Preferably, the initial compression ratio A0 should be less than 30%, and the preferred value range is 15% to 25%. The higher the compression ratio, the better the sealing effect.

[0076] Based on the conventional dimensions and specifications of the sealing ring for the lubrication oil hole of the main bearing of the tunneling machine, the preset depth h0 of the sealing groove ranges from 1.92mm to 4.34mm; preferably, it is 2.75mm.

[0077] S303. Determine whether the initial compression ratio of the sealing ring is less than the preset compression ratio. If yes, proceed to S304; otherwise, proceed to S310.

[0078] S304. Determine the contact width of the sealing ring based on its cross-sectional diameter and initial compression ratio.

[0079] like Figure 6 As shown, b1 is the contact width of the sealing ring.

[0080] Specifically, based on the sealing ring cross-sectional diameter d2 and the initial compression ratio A0, the following formula is used:

[0081]

[0082] Determine the contact width b1 of the sealing ring.

[0083] S305. Determine whether the contact width of the sealing ring is less than the preset ratio of the preset width of the sealing groove. If yes, proceed to S306; otherwise, proceed to S311.

[0084] Specifically, based on the diameter d2 of the sealing ring section and the depth h between the bottom of the sealing groove and the sealed surface, the following formula is used:

[0085]

[0086] Determine the preset width b of the sealing groove.

[0087] The preset ratio is generally set to 1 / 2 to 3 / 4; based on the commonly used size specifications of the sealing ring for the lubrication oil hole of the main bearing of the tunneling machine, the width of the sealing groove is 5.00mm.

[0088] Furthermore, different fillet radii at the bottom of the groove affect the contact pressure and stress of the sealing ring. If the fillet is too sharp, it may cause damage to the sealing ring under pressure. At the same time, fillet radii at the bottom of the groove can also prevent stress concentration. Therefore, the fillet radius at the bottom of the sealing groove should be rationally designed while comprehensively considering ease of processing. The fillet radius at the bottom of the sealing groove should be designed according to the depth and width of the sealing groove, with a range of 0.3mm to 0.8mm, preferably 0.5mm. Chamfering the groove edges can prevent cuts and scratches during sealing ring assembly. If the chamfer is too large, the sealing ring will be squeezed out; if the chamfer is too small, the sealing ring will be cut. Therefore, the chamfering of the sealing groove edges should be rationally designed while comprehensively considering ease of processing. The chamfering of the sealing groove edges should be designed according to the depth and width of the sealing groove, with a range of 0.1mm to 0.3mm, preferably 0.2mm.

[0089] S306. Determine the deformation width of the sealing ring based on the initial compression ratio and the diameter of the sealing ring cross section.

[0090] like Figure 6 As shown, b2 is the width of the sealing ring after deformation.

[0091] Specifically, based on the initial compression ratio A0 and the diameter d2 of the sealing ring section, the following formula is used:

[0092] b2=(4A0 2 +0.34A0+0.31)×d2

[0093] Determine the deformation width b2 of the sealing ring.

[0094] Preferably, the width b2 of the sealing ring after deformation should be approximately equal to the width b of the sealing groove.

[0095] S307. Determine whether the deformation width of the sealing ring is less than the preset width of the sealing groove. If yes, proceed to S308; otherwise, proceed to S312.

[0096] S308. Determine the cross-sectional fill rate of the sealing ring based on the preset depth of the sealing groove, the cross-sectional diameter of the sealing ring, and the preset width of the sealing groove.

[0097] Specifically, based on the preset depth h0 of the sealing groove, the diameter d2 of the sealing ring cross-section, and the preset width b0 of the sealing groove, the following formula is used:

[0098]

[0099] Determine the cross-sectional fill rate E of the sealing ring.

[0100] The cross-sectional fill rate E ranges from 70% to 90%, preferably from 75% to 85%.

[0101] S309. Determine whether the cross-sectional fill rate of the sealing ring is greater than the preset fill rate threshold. If yes, execute S313. If no, delete the sealing ring of that specification and execute S301 to obtain the specification of the next sealing ring.

[0102] S310. Increase the preset depth of the sealing groove by a preset unit amount until the compression ratio of the sealing ring is less than the preset compression ratio, thus obtaining the first depth of the sealing groove.

[0103] S311. Increase the first depth of the sealing groove by a preset unit amount until the contact width of the sealing ring is less than a preset ratio of the preset width of the sealing groove, thus obtaining the second depth of the sealing groove.

[0104] S312. Reduce the second depth by a preset unit amount until the deformation width of the sealing ring is less than the preset width of the sealing groove, thus obtaining the third depth of the sealing groove.

[0105] Specifically, the depth of the sealing groove is related to the cross-sectional compression ratio of the sealing ring. When the sealing groove is too deep, the interference of the sealing ring is insufficient, and the sealing effect cannot be achieved. When the sealing groove is too shallow, the sealing ring may be squeezed and burst when the upper and lower end faces are assembled. Therefore, the depth of the sealing groove should be reasonably designed according to the specifications of the sealing ring in order to increase the required contact pressure and achieve a better sealing effect.

[0106] S313. Determine the initial elongation rate of the sealing ring based on the inner diameter of the sealing ring and the preset inner diameter of the sealing groove.

[0107] Specifically, the inner diameter of the sealing groove determines its approximate position. If the distance between the sealing groove and the lubricating oil hole or the edge of the ring is too small, structural damage may occur during use or installation, resulting in poor lubrication and sealing. This allows contaminants to enter the main bearing and main drive, causing damage to the entire machine. It also increases the machining difficulty of the main bearing. The inner diameter of the sealing groove should be designed reasonably according to the specifications of the lubricating oil hole and the layout space of the oil groove. The inner diameter of the sealing ring should also be designed reasonably according to the inner diameter of the sealing groove. That is, the inner diameter of the sealing ring in its free state should be slightly smaller than the inner diameter of the sealing groove to generate elastic deformation and form a pre-tightening force, thereby preventing the sealing ring from falling off. If the inner diameter of the sealing ring is too small, it cannot be assembled onto the inner diameter of the sealing groove. Forced assembly will cause damage to the sealing ring and loss of sealing effect. If the inner diameter of the sealing ring is too large, it cannot fit with the inner diameter of the sealing groove, causing the sealing ring to fall off and failing to achieve the sealing function.

[0108] Based on the inner diameter d1 of the sealing ring and the stretching amount α, the following formula is used:

[0109] a0=αd1

[0110] Determine the preset inner diameter a0 of the sealing groove.

[0111] Among them, the inner diameter d1 of the sealing ring is the inner diameter of the sealing ring in the free state; the tensile amount α ranges from 1.01 to 1.06, and considering the sealing conditions required by the tunneling machine, α is preferably 1.05; the minimum value of the preset inner diameter a0 of the sealing groove is n1+n2+d3, where d3 is the diameter of the lubricating oil hole. Based on the common specifications of the lubricating oil hole d3 of existing tunneling machines, the cross-sectional diameter of the sealing ring is pre-selected as 3.55mm.

[0112] Based on the inner diameter d1 of the sealing ring and the preset inner diameter a0 of the sealing groove, the following formula is used:

[0113]

[0114] Determine the initial tensile strength B0 of the sealing ring.

[0115] S314. Determine whether the initial stretch rate of the sealing ring is less than the preset stretch rate. If yes, execute S317; otherwise, execute S315.

[0116] Specifically, the preset elongation rate should be less than 10%, and the preferred range is 3% to 9%.

[0117] S315. Reduce the preset inner diameter of the sealing groove by a preset unit amount until the elongation of the sealing ring is less than the preset elongation, and obtain the first inner diameter of the sealing groove.

[0118] S316. Based on the first depth, second depth, or third depth of the sealing groove, the diameter of the sealing ring section, and the preset width of the sealing groove, determine the contact width, deformation width, and cross-sectional filling rate of the sealing ring corresponding to the first depth, second depth, or third depth.

[0119] Specifically, the calculation methods for the contact width, deformation width, and cross-sectional fill rate of the sealing ring corresponding to the second or third depth are similar to those for the sealing ring corresponding to the first depth, except that the first depth is replaced by the second or third depth. This embodiment will not be elaborated further here.

[0120] S317. The preset depth, first depth, second depth or third depth, and preset inner diameter or first inner diameter corresponding to the preset compression rate, preset elongation rate, preset cross-sectional filling rate and preset elongation rate are sent to the processing terminal as target parameters that match the specifications of the sealing ring, so that the processing terminal can process the sealing groove according to the target parameters.

[0121] The method provided in this embodiment obtains the specifications of the sealing ring, including the inner diameter and cross-sectional diameter of the sealing ring; determines the initial compression ratio of the sealing ring based on the cross-sectional diameter of the sealing ring and the preset depth of the sealing groove; determines whether the initial compression ratio of the sealing ring is less than the preset compression ratio; if so, determines the contact width of the sealing ring based on the cross-sectional diameter of the sealing ring and the initial compression ratio; if not, increases the preset depth of the sealing groove by a preset unit amount until the compression ratio of the sealing ring is less than the preset compression ratio, thus obtaining the first depth of the sealing groove. By adjusting the depth, the compression ratio of the sealing ring is adjusted, thereby adjusting the tightness of the sealing ring in the sealing groove by changing the compression ratio, thereby improving the sealing effect.

[0122] By determining whether the contact width of the sealing ring is less than a preset proportion of the preset width of the sealing groove, if so, the deformation width of the sealing ring is determined based on the initial compression ratio and the diameter of the sealing ring cross-section; if not, the first depth of the sealing groove is increased by a preset unit amount until the contact width of the sealing ring is less than a preset proportion of the preset width of the sealing groove, thus obtaining the second depth of the sealing groove. The matching degree between the sealing ring and the sealing groove is improved by utilizing the width of the sealing ring before and after deformation.

[0123] By determining whether the deformation width of the sealing ring is less than the preset width of the sealing groove, if so, the cross-sectional filling rate of the sealing ring is determined based on the preset depth of the sealing groove, the cross-sectional diameter of the sealing ring, and the preset width of the sealing groove; if not, the second depth is reduced by a preset unit amount until the deformation width of the sealing ring is less than the preset width of the sealing groove, thus obtaining the third depth of the sealing groove. The cross-sectional filling rate is used to further determine the matching degree between the sealing ring and the sealing groove, so as to further improve the sealing effect.

[0124] By determining whether the cross-sectional fill rate of the sealing ring is greater than a preset fill rate threshold, if so, the initial stretch rate of the sealing ring is determined based on the inner diameter of the sealing ring and the preset inner diameter of the sealing groove. If the initial stretch rate of the sealing ring is not less than the preset stretch rate, the preset inner diameter of the sealing groove is reduced by a preset unit amount until the stretch rate of the sealing ring is less than the preset stretch rate, thus obtaining the first inner diameter of the sealing groove. If not, the sealing ring of that specification is deleted, and the specification of the next sealing ring is obtained. The stretch rate is used to adjust the inner diameter of the sealing groove, thereby adjusting the width of the sealing groove to improve the sealing effect of the sealing ring and the sealing groove.

[0125] Based on the first, second, or third depth of the sealing groove, the diameter of the sealing ring cross-section, and the preset width of the sealing groove, the contact width, deformation width, and cross-sectional fill rate of the sealing ring corresponding to the first, second, or third depth are determined respectively. The depth and inner diameter that meet the preset compression rate, preset elongation rate, preset cross-sectional fill rate, and preset elongation rate are sent to the processing terminal as target parameters that match the specifications of the sealing ring. This allows the processing terminal to process the sealing groove according to the target parameters. The preset compression rate, preset elongation rate, preset cross-sectional fill rate, and preset elongation rate guide the adjustment of the depth and inner diameter of the sealing groove, thereby making the sealing groove and the sealing ring fit more tightly and improving the sealing effect.

[0127] The acquisition module 401 is used to acquire the specifications of the sealing ring, which include the inner diameter and the cross-sectional diameter of the sealing ring.

[0128] The processing module 402 is used to determine target parameters that match the sealing ring based on the inner diameter of the sealing ring, the cross-sectional diameter of the sealing ring, the preset inner diameter, preset width, preset depth of the sealing groove, the preset compression rate, preset elongation rate, and preset cross-sectional filling rate of the sealing ring; wherein, the target parameters include the inner diameter and depth of the sealing groove that simultaneously meet the preset compression rate, preset elongation rate, and preset cross-sectional filling rate range.

[0129] The sending module 403 is used to send the target parameters to the processing terminal so that the processing terminal can process the sealing groove according to the target parameters.

[0130] Optionally, the processing module 402 is specifically used to: determine target parameters matching the sealing ring based on the inner diameter of the sealing ring, the cross-sectional diameter of the sealing ring, and the preset inner diameter, preset width, and preset depth of the sealing groove, as well as the preset compression rate, preset elongation rate, and preset cross-sectional filling rate of the sealing ring, including:

[0131] The initial compression ratio of the sealing ring is determined based on the cross-sectional diameter of the sealing ring and the preset depth of the sealing groove.

[0133] If the initial elongation of the sealing ring is less than the preset elongation, the contact width of the sealing ring is determined based on the cross-sectional diameter and initial compression ratio of the sealing ring.

[0134] If the contact width of the sealing ring is less than a preset ratio of the preset width of the sealing groove, the deformation width of the sealing ring is determined according to the initial compression ratio and the diameter of the sealing ring cross section.

[0135] If the deformation width of the sealing ring is less than the preset width of the sealing groove, the cross-sectional fill rate of the sealing ring is determined according to the preset depth of the sealing groove, the cross-sectional diameter of the sealing ring, and the preset width of the sealing groove.

[0136] If the cross-sectional fill rate of the sealing ring is not less than the preset fill rate threshold, then the preset depth of the sealing groove and the preset inner diameter of the sealing groove are used as target parameters that match the specifications of the sealing ring.

[0137] Furthermore, based on the above embodiments, the processing module 402 can also be used to: if the initial compression ratio of the sealing ring is not less than the preset compression ratio, increase the preset depth of the sealing groove by a preset unit amount until the compression ratio of the sealing ring is less than the preset compression ratio, and obtain the first depth of the sealing groove.

[0138] Based on the first depth of the sealing groove, the diameter of the sealing ring section, and the preset width of the sealing groove, the contact width, deformation width, and cross-sectional filling rate of the sealing ring corresponding to the first depth are determined. When the contact width, deformation width, and cross-sectional filling rate of the sealing ring all meet the preset compression rate, preset tensile rate, and preset cross-sectional filling rate, the first depth of the sealing groove and the preset inner diameter of the sealing groove are taken as target parameters that match the specifications of the sealing ring.

[0139] Furthermore, based on the above embodiments, the processing module 402 can also be used to: if the contact width of the sealing ring is not less than a preset proportion of the preset width of the sealing groove, then increase the preset depth of the sealing groove by a preset unit amount until the contact width of the sealing ring is less than a preset proportion of the preset width of the sealing groove, thereby obtaining a second depth of the sealing groove.

[0140] Based on the second depth of the sealing groove, the diameter of the sealing ring section, and the preset width of the sealing groove, the contact width, deformation width, and cross-sectional filling rate of the sealing ring corresponding to the second depth are determined. When the contact width, deformation width, and cross-sectional filling rate of the sealing ring all meet the preset compression rate, preset tensile rate, and preset cross-sectional filling rate, the second depth of the sealing groove and the preset inner diameter of the sealing groove are taken as target parameters that match the specifications of the sealing ring.

[0141] Furthermore, based on the above embodiments, the processing module 402 can also be used to: if the deformation width of the sealing ring is not less than the preset width of the sealing groove, reduce the second depth by a preset unit amount until the deformation width of the sealing ring is less than the preset width of the sealing groove, and obtain the third depth of the sealing groove.

[0142] Based on the third depth of the sealing groove, the diameter of the sealing ring section, and the preset width of the sealing groove, the contact width, deformation width, and cross-sectional filling rate of the sealing ring corresponding to the third depth are determined. When the contact width, deformation width, and cross-sectional filling rate of the sealing ring all meet the preset compression rate, preset tensile rate, and preset cross-sectional filling rate, the third depth of the sealing groove and the preset inner diameter of the sealing groove are taken as target parameters that match the specifications of the sealing ring.

[0143] Furthermore, based on the above embodiments, the processing module 402 can also be used to: if the initial stretch rate of the sealing ring is not less than the preset stretch rate, reduce the preset inner diameter of the sealing groove by a preset unit amount until the stretch rate of the sealing ring is less than the preset stretch rate, and obtain the first inner diameter of the sealing groove.
