[0041] The threaded mounting hole of the main bearing of the tunnel boring machine is the key power transmission part of the main bearing of the tunnel boring machine. The power is transmitted to the cutterhead of the tunnel boring machine through the threaded mounting hole of the main bearing, studs and a series of flanges to achieve tunneling operations. Since there are a series of components between the threaded mounting hole and the cutterhead, the length of the studs used is generally more than 500mm, which places high requirements on the verticality of the thread of the threaded mounting hole of the main bearing.

[0042] If the verticality of the thread exceeds the specified value, it will cause uneven force on the stud. In severe cases, it will lead to problems such as the inability to install the stud, bolt breakage, and power transmission failure. During the main bearing processing, the verticality of the thread needs to be checked after the mounting hole thread is tapped to determine whether it meets the design requirements. In the related technology, after the mounting hole thread is tapped, a thread calibration rod, a square ruler, etc. are generally used to cooperate in the detection of the verticality of the thread. However, the detection accuracy of this detection method is affected by the accuracy of the thread calibration rod and the square ruler, there are many human factors, and the detection efficiency is low.

[0043] Based on the above-mentioned technical problems, the embodiments of the present application provide a thread verticality detection and analysis device and equipment, including a support component, which can play the role of a reference support during the detection process, thereby helping to ensure the stability of the device during the detection process and to maximize the detection accuracy of the detection component; including a detection component. Compared with the detection method of the prior art, the detection method of the present application has a high degree of automation and high detection accuracy, and the detection results are less affected by human factors, so that the verticality of the thread calibration rod can be detected quickly and accurately, and then the verticality of the threaded hole being detected can be reflected, thereby helping to analyze the deviation direction of the thread; including a drive component, which has a high degree of automation, helps to ensure that it is not interfered with by human factors and improves the user experience.

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Reference Figure 1 As shown, an embodiment of the present application provides a device 200 including a thread calibration rod 210 and a thread verticality detection and analysis device 100 . The thread calibration rod 210 is vertically screwed into a threaded hole 310 to be detected of a workpiece 300 .

[0046] The detection object is not limited. For example, the detection object of the thread verticality detection and analysis device 100 of this embodiment is mainly to detect the thread verticality of the main bearing mounting hole of the tunnel boring machine. It should be noted that the detection object includes but is not limited to the above detection objects, and can be used according to actual needs.

[0047] The specific structure of the workpiece 300 is not limited. For example, the workpiece 300 may be a general mechanical part; or, the workpiece 300 may be a component for transmitting power; or, the workpiece 300 may be a seal. This is not limited in this embodiment. It can be set according to actual needs. In addition, the processing method of the detected threaded hole 310 on the workpiece 300 is not limited.

[0048] It should be noted that the detection object of the thread verticality detection and analysis device 100 in this embodiment is mainly the thread verticality of the detected threaded hole 310 in the workpiece 300. Among them, since the verticality of the detected threaded hole 310 is detected by a square ruler or the like in the related art, the detection accuracy is low. Therefore, in this embodiment, in order to improve the thread verticality of the detected threaded hole 310, a thread calibration rod 210 matching the detected threaded hole 310 is used. By detecting the verticality of the thread calibration rod 210, the thread verticality of the detected threaded hole 310 can be reflected, and it is helpful to analyze the deviation direction of the verticality, and analyze the cause of the deviation according to the actual situation.

[0049] The threaded rod 210 is a tool for detecting the verticality of threaded holes. Figure 7 As shown, it generally includes a calibration rod body 211 and a detection screw 212. The detection screw 212 is a detection standard part that matches the detected threaded hole 310 and is usually a screw structure. The detection screw 212 is sleeved on the calibration rod body 211.

[0050] The detection principle of the threaded calibration rod 210 is: the detection screw 212 is vertically screwed into the detected threaded hole 310. Since the detection screw 212 and the detected threaded hole 310 match each other, after being screwed in, if the detected threaded hole 310 has a displacement deviation, it means that the detection screw 212 has a displacement deviation, and the displacement deviation values ​​of the two are the same. Therefore, in the implementation of this application, by detecting the verticality of the detection screw 212, the verticality of the detected threaded hole 310 is reflected.

[0051] It should be noted that the threaded rod 210 is vertically screwed into the detected threaded hole 310. This helps to ensure that the threaded rod 210 and the horizontal plane of the workpiece 300 are in a completely vertical state, thereby helping to improve the detection accuracy of the verticality of the detected threaded hole 310 relative to the surface of the workpiece 300.

[0052] In order to further improve the detection accuracy of the threaded calibration rod 210, in the embodiment of the present application, a plurality of grooves 213 may be provided on the outer surface of the calibration rod body 211 along the outer circumference of the threaded calibration rod 210, and the detection probe 132 of the thread verticality detection and analysis device 100 is attached to the grooves 213.

[0053] In this way, the detection probe 132 can be limited by the design of the groove 213, and the detection probe 132 slides in the groove 213 to detect the verticality of the threaded calibration rod 210, thereby improving the detection accuracy. Therefore, the present application can analyze the deviation direction of the thread by detecting the verticality of each groove 213 on the threaded calibration rod 210.

[0054] In the embodiment of the present application, the shape of the groove 213 is not limited. For example, the bottom of the groove 213 can be a plane; or, the bottom of the groove 213 can be a curved surface; or, the bottom of the groove 213 can be a surface of other shapes. In this embodiment, the bottom of the groove 213 is mainly described as a plane, which helps to improve the fit between the detection probe 132 and the groove 213, thereby maximizing the detection accuracy of the verticality of the threaded calibration rod 210.

[0055] In the embodiment of the present application, there is no limitation on the number of grooves 213. For example, the number of grooves 213 can be two, three, five or more. The more the number, the more conducive it is to analyze the direction of thread deviation. In the present embodiment, eight grooves 213 are mainly used as an example for explanation.

[0056] In the embodiment of the present application, the arrangement of the plurality of grooves 213 is not limited. Figure 1 As shown, a plurality of grooves 213 are arranged around the circumference of the threaded calibration rod 210. In this way, the verticality of the threaded calibration rod 210 in multiple directions can be detected, thereby reflecting the verticality of the detected threaded hole 310 in multiple directions, and maximizing the detection accuracy. At the same time, it is helpful to analyze the deviation direction of the verticality and analyze the cause of the deviation.

[0057] In the embodiment of the present application, there is no limitation on the size of the groove 213. For example, the length of the groove 213 may extend from the bottom to the top of the threaded calibration rod 210; in addition, there is no limitation on the groove depth and groove diameter of the groove 213, and this embodiment does not limit this.

[0058] The structure of the thread verticality detection and analysis device of the present application is described in detail below.

[0059] Reference Figure 2 and Figure 3 As shown, an embodiment of the present application provides a thread verticality detection and analysis device 100, including a support component 110 and a detection component 130.

[0060] In the embodiment of the present application, the support assembly 110 is connected to the workpiece 300, and the threaded calibration rod 210 is passed through the support assembly 110, so that the threaded calibration rod 210 is vertically screwed into the threaded hole 310 to be detected. In this way, the support assembly 110 can play the role of reference support during the detection process, which is beneficial to ensure the stability of the device during the detection process and maximize the detection accuracy of the detection assembly 130.

[0061] In the embodiment of the present application, there is no limitation on the shape, size, etc. of the support assembly 110. For example, the support assembly 110 in the present embodiment may be a frame structure, and the threaded calibration rod 210 may be directly inserted therethrough; or, the support assembly 110 may be a columnar structure, and a through hole is provided on the support assembly 110 for the threaded calibration rod 210 to be inserted therethrough.

[0062] In this embodiment, the support assembly 110 is mainly described as a frame structure. Figure 2 and Figure 3 As shown, the support assembly 110 may have a connected top opening 111 and a bottom opening, and the threaded calibration rod 210 is sequentially passed through the top opening 111 and the bottom opening 112, and is screwed into the detected threaded hole 310. The size, shape, etc. of the top opening 111 and the bottom opening 112 are not limited and can be specifically set according to actual needs.

[0063] In the embodiment of the present application, there is no limitation on the connection method between the support assembly 110 and the workpiece 300. For example, the support assembly 110 and the workpiece 300 may be connected by bonding; or the support assembly 110 and the workpiece 300 may be connected by screwing; or the support assembly 110 and the workpiece 300 may be connected by clamping or welding. This embodiment does not limit this, and it can be specifically set according to actual needs.

[0064] In the embodiment of the present application, the structure of the detection component 130 is not limited. Exemplarily, the detection component 130 can be a laser detector. The principle of laser detection is to use the laser beam emitted by the laser to illuminate the object to be measured, and calculate the verticality error value by measuring the position change of the laser beam after it is reflected or passes through the object to be measured. Alternatively, the detection component 130 can be a light detector. The principle of light detection is to use the refraction angle of light when it is reflected to determine the verticality of the plane; or, the detection component 130 can be a scale measuring device. The principle of scale measurement is to calculate the deviation value by measuring the distance between the upper and lower positions of the object and the vertical reference; or, the detection component 130 can be a bubble detector. The bubble detector uses the floating of bubbles in the liquid to determine the position of the horizontal plane, thereby determining the verticality. This embodiment does not limit this.

[0065] In this way, compared with the detection method of the prior art, the detection method of the present application has the advantages of high degree of automation and high detection accuracy, and the detection results are less affected by human factors, so that the verticality of the threaded calibration rod 210 can be quickly and accurately detected, and then the verticality of the threaded hole 310 being detected can be reflected.

[0066] In order to further improve the detection accuracy of the threaded calibration rod 210, in the embodiment of the present application, referring to Figure 3 and Figure 4 As shown, it can also include a driving component 120, which is movably connected to the supporting component 110, and the detection component 130 is connected to the driving component 120, and the driving component 120 is configured to drive the detection component 130 to move so that at least part of the detection component 130 abuts against the outer surface of the threaded calibration rod 210.

[0067] In the embodiment of the present application, there is no limitation on the connection method between the drive assembly 120 and the support assembly 110. For example, the drive assembly 120 and the support assembly 110 may be movably connected via a movable member; or the drive assembly 120 and the support assembly 110 may be movably connected via a rotating member. This embodiment does not limit this.

[0068] In the embodiment of the present application, there is no limitation on the moving direction of the drive component 120 driving the detection component 130. Exemplarily, the drive component 120 can drive the detection component 130 to rotate circumferentially around the threaded calibration rod 210, so that 360° detection of the threaded calibration rod 210 can be achieved, which helps to improve the detection accuracy; or, the drive component 120 can drive the detection component 130 to move vertically around the axial direction of the threaded calibration rod 210. In this way, multi-position detection can be performed on the same direction of the threaded calibration rod 210, which helps to improve the detection accuracy. This embodiment does not limit this.

[0069] Therefore, the thread verticality detection and analysis device 100 provided in this embodiment has a high degree of automation in the detection method, high detection accuracy, and the detection results are less affected by human factors. It is thus possible to quickly and accurately detect the verticality of the thread calibration rod 210, and then reflect the verticality of the detected threaded hole 310, thereby improving the user experience.

[0070] In one possible implementation, referring to Figure 1 , Figure 2 and Figure 5 As shown, the detection assembly 130 may include a detection body 131 and a detection probe 132 connected to the detection body 131 , and the detection body 131 is connected to the driving assembly 120 .

[0071] In the embodiment of the present application, the structure of the detection body 131 is not further limited. For example, the detection body 131 can be a detection rod; the detection probe 132 can be a high-sensitivity sensor, and for example, the detection probe 132 can be a verticality measurement sensor. This embodiment does not limit this.

[0072] The driving assembly 120 is configured to drive the detection body 131 to move, and the detection probe 132 is configured to detect the verticality of the threaded calibration rod 210. In this way, during the detection process, not only the stability of the detection can be guaranteed, but also the detection accuracy can be improved to the greatest extent.

[0073] In one possible implementation, referring to Figure 5 As shown, the support assembly 110 may be connected to an engagement member 140, and the drive assembly 120 may include a circumferential drive member 121, at least part of which is engaged with the engagement member 140. The circumferential drive member 121 is configured to rotate around the circumference of the engagement member 140 to drive the detection assembly 130 to rotate around the circumference of the threaded calibration rod 210.

[0074] In the embodiment of the present application, there is no limitation on the structure of the engagement member 140. For example, the engagement member 140 in the present embodiment can be a gear ring, which is engaged with at least a portion of the circumferential driving member 121, so that power transmission during the rotation process can be achieved, thereby maximally achieving the rotation of the circumferential driving member 121, and further achieving the rotation of the detection assembly 130.

[0075] In one possible implementation, referring to Figure 5 As shown, the detection body 131 may be provided with a circumferential driving rack 133, and the circumferential driving member 121 may include a circumferential driving unit 1211 and a circumferential rotating gear 1212. The circumferential driving unit 1211 is configured to drive the circumferential rotating gear 1212 to rotate, and the circumferential rotating gear 1212 and the circumferential driving rack 133 are meshed.

[0076] Exemplarily, the circular driving unit 1211 in this embodiment may be a motor.

[0077] In the embodiment of the present application, the circumferential driving unit 1211 is used to provide power to the circumferential rotating gear 1212. In this way, the circumferential rotation of the detection component 130 is realized through the cooperation of the circumferential rotating gear 1212 and the circumferential driving rack 133, and the circumferential verticality of the threaded calibration rod 210 is detected, thereby reflecting the circumferential verticality of the detected threaded hole 310, thereby improving the detection accuracy.

[0078] In one possible implementation, referring to Figure 5 As shown, the driving assembly 120 may further include a vertical driving member 122 , which is configured to drive the detection assembly 130 to translate along the axial direction of the threaded calibration rod 210 , so as to drive the detection assembly 130 to move along the axial direction of the threaded calibration rod 210 .

[0079] The translation along the axial direction of the threaded calibration rod 210 may include: the vertical drive member 122 is configured to drive the detection assembly 130 to move upward in the vertical direction; or the vertical drive member 122 is configured to drive the detection assembly 130 to move downward in the vertical direction. This embodiment does not limit this. In this way, the threaded calibration rod 210 can be detected in multiple positions in the same direction, which helps to improve the detection accuracy.

[0080] In one possible implementation, referring to Figure 5 As shown, a vertical driving rack 134 may be provided on the detection body 131, and the vertical driving member 122 may include a vertical driving unit 1221 and a vertical rotating gear 1222; the vertical driving unit 1221 is configured to drive the vertical rotating gear 1222 to move in translation, and the vertical rotating gear 1222 and the vertical driving rack 134 are meshed.

[0081] Exemplarily, the vertical driving unit 1221 in this embodiment may be a motor.

[0082] In an embodiment of the present application, the vertical driving unit 1221 is used to provide power to the vertical rotating gear 1222, so that the detection component 130 can be moved in the vertical direction through the engagement of the vertical rotating gear 1222 and the vertical driving rack 134, thereby realizing the verticality detection of the threaded calibration rod 210 in the vertical direction, and then reflecting the verticality of the detected threaded hole 310 in the vertical direction, thereby improving the detection accuracy.

[0083] In one possible implementation, referring to Figures 1 to 4As shown, a slewing bearing 150 may be connected between the support assembly 110 and the driving assembly 120, and the driving assembly 120 includes a connecting plate 123. The circumferential driving member 121 rotates around the circumferential direction of the engagement member 140 through the connecting plate 123 and the slewing bearing 150.

[0084] The slewing bearing 150 is a large bearing capable of bearing a comprehensive load, and is mainly composed of an inner ring, an outer ring, rolling elements, and seals. The slewing bearing 150 moves objects by sliding or rolling to reduce frictional resistance. Its working principle is mainly to achieve rotation by the rolling motion of the rolling elements between the inner and outer rings.

[0085] The outer ring of the slewing bearing 150 is fixedly connected to the support assembly 110, and the inner ring of the slewing bearing 150 is movably connected to the connecting plate 123. It should be noted that the inner ring and the outer ring are the basic structure of the slewing bearing 150, mainly providing the basis for the rotation of the slewing bearing 150.

[0086] In this way, by including the slewing bearing 150, the circumferential driving member 121 rotates around the circumferential direction of the engaging member 140 through the connecting plate 123 and the slewing bearing 150, thereby realizing load transfer and being beneficial to improving stability during rotation, thereby ensuring the detection effect of the device of the present application.

[0087] In one possible implementation, referring to Figures 1 to 3 As shown, the support assembly 110 may include an upper support plate 113 , a lower support plate 114 , and a plurality of support rods 115 connected between the upper support plate 113 and the lower support plate 114 ; the slewing bearing 150 is connected between the upper support plate 113 and the connecting plate 123 .

[0088] In this embodiment, there is no limitation on the size, shape, material, etc. of the upper support plate 113 and the lower support plate 114. For example, the upper support plate 113 and the lower support plate 114 can both be annular structures, with the top opening 111 opened on the upper support plate 113 and the bottom opening 112 opened on the lower support plate 114.

[0089] In this embodiment, there is no limitation on the number of support rods 115. For example, the number of support rods 115 can be two, three, six or more. This embodiment does not limit this and can be set according to actual needs.

[0090] In addition, there is no limitation on the connection method between the support rod 115 and the upper support plate 113 and the lower support plate 114. For example, the support rod 115 and the upper support plate 113 and the lower support plate 114 can be connected by screws, respectively; or the support rod 115 and the upper support plate 113 and the lower support plate 114 can be connected by bonding or welding.

[0093] In this embodiment, the thread verticality detection and analysis device 100 may further include a flatness detection member. The flatness detection member is connected to the support assembly 110 and is configured to detect the flatness of the thread verticality detection and analysis device 100 .

[0094] Exemplarily, the flatness detection part can be a flatness detector. A flatness detector is an instrument designed according to the principle of optical autocollimation, which can accurately measure the straightness error of a machine tool or instrument guide rail, the flatness error of a flat plate, etc., the straightness error of a vertical guide rail, and the verticality error between a vertical guide rail and a horizontal guide rail. In this embodiment, the specific structure of the flatness detection part is not limited, and as long as the flatness of the thread verticality detection and analysis device 100 can be detected, it belongs to the protection scope of this application.

[0095] In this embodiment, refer to Figure 8 As shown, a plane adjusting member 170 may be further included. The plane adjusting member 170 is connected between the suction member 160 and the support assembly 110 . The plane adjusting member 170 is configured to adjust the parallelism between the support assembly 110 and the workpiece 300 .

[0096] Specifically, the plane adjustment member 170 is connected between the suction member 160 and the lower support plate 114, and can adjust the parallelism between the lower support plate 114 and the workpiece 300 to ensure that the detection component 130 is completely perpendicular to the workpiece 300, thereby maximizing the detection accuracy of the detection component 130, and can quickly and accurately detect the verticality of the threaded calibration rod 210, thereby reflecting the verticality of the threaded hole 310 being detected.

[0097] Exemplarily, the plane adjustment member 170 may be a level meter. The level meter can be used to determine whether the surface of the device is flat. During use, the level meter is placed on the surface of the device, and the bubbles in the level meter are observed to determine whether the device is level.

[0098] The thread verticality detection and analysis device and equipment provided in the embodiments of the present application include a support component, which can serve as a reference support during the detection process, thereby helping to ensure the stability of the device during the detection process and maximally ensure the detection accuracy of the detection component; including a detection component.
