Description

Technical Field

[0001] This invention relates to the field of detector oil injection and pressurization technology, specifically to a detector oil injection and pressurization device. Background Technology

[0002] In marine seismic exploration, the geophone is one of the most critical components of the acquisition cable, used to receive reflected waves from the strata. Current geophones typically consist of a cylindrical protective shell and a transducer installed inside it. A protective sleeve is fitted over the outer shell, with the inner walls at both ends of the sleeve fixedly connected to the outer walls at both ends of the protective shell. The outer wall of the protective shell surrounding the mounting groove is fixedly connected to the inner wall of the protective sleeve, thus forming several independent sealed chambers between the protective shell and the protective sleeve. To ensure effective transmission of seismic waves and to buffer and protect the transducer, these chambers need to be filled with hydraulic oil and maintained at a certain pressure.

[0003] Currently, the oil filling and pressurization process of the detector is mainly carried out manually. Specifically, the operator uses a manual oil filling tool to fill each chamber one by one through the oil filling hole at the end of the protective shell. After the oil filling is completed, the chamber is pressurized by a manual pressurization tool, and finally the bolt is manually screwed in to seal the oil filling hole.

[0004] The above-mentioned manual operation method has the following technical problems: First, the amount of oil injected is difficult to control precisely: when injecting oil manually, operators rely on experience and visual judgment to determine the amount of oil to inject. There are significant differences in the amount of oil injected by different operators and different batches, which leads to inconsistent oil volume inside the same batch of detectors, affecting the stability of seismic wave transmission and the protective effect of the transducer.

[0005] Second, the pressurization pressure cannot be uniform: When pressurizing manually, the operator judges the pressure by touch, which makes it difficult to ensure that the pressurization pressure of each chamber is exactly the same. Some chambers may have insufficient pressure or excessive pressure. Insufficient pressure will affect the efficiency of seismic wave transmission, while excessive pressure may damage the sealing structure.

[0006] Third, low production efficiency: Each detector usually contains multiple independent chambers, which need to be filled with oil, pressurized and sealed one by one. The manual operation is cumbersome and time-consuming, making it difficult to meet the needs of large-scale production.

[0007] Fourth, poor sealing reliability: The bolts used for sealing the oil injection hole are tightened manually, and the tightening torque cannot be precisely controlled. This can easily lead to problems such as insufficient tightening causing leakage or over-tightening causing thread damage, affecting the long-term reliability of the detector.

[0008] Based on this, the present invention designs a detector oil injection and pressurization device to solve the above problems. Summary of the Invention

The transition surface gradually slopes upward from the bottom. A fixing component is elastically slidably connected to the contact component. The fixing component contacts the transition surface. A locking component is provided above the transition surface. The locking component has a groove. The contact component has a snap-fit ​​part corresponding to the groove. The triggering component includes a trigger rod that is elastically slidably connected to the connecting sleeve and a baffle that is elastically rotatably disposed on the connecting sleeve. The trigger rod is provided with an unlocking mechanism, which is used to force the baffle to rotate from vertical to tilt after the trigger rod is compressed upward to a specified degree, thereby causing the fixing component to be released elastically in an instant. The release component is used to unlock the fixing member from the locking member; The bottom end of the contact element is provided with several contact wheels that can rotate.

[0012] As a further embodiment of the present invention, the unlocking mechanism includes a limiting piece and an arc-shaped component. The limiting piece is elastically slidably connected to the connecting sleeve, and its bottom end is located between the limiting piece and the arc-shaped component. The arc-shaped component is fixed to the side wall of the baffle.

[0013] As a further embodiment of the present invention, the release component includes a lever that rotates elastically on the connecting sleeve. The locking member is elastically slidably connected to the connecting sleeve. The top end of the lever is located on one side of the locking member. During the process of the trigger rod resetting from the top downwards, it pushes the lever to rotate and pushes the locking member away from the fixing member through the top end of the lever.

[0014] As a further embodiment of the present invention, the base platform is provided with a plurality of first slide rails, the first mobile platform is slidably mounted on the first slide rails, and the two ends of the first slide rails are respectively provided with limiting anti-collision seats. The driving mechanism is a cylinder, which is mounted on the base platform and driven by the first mobile platform.

[0015] As a further embodiment of the present invention, the top of the first mobile platform is provided with a plurality of clamping components, the clamping components are opened or closed by clamping cylinders, and the bottom of the clamping components is provided with a positioning base for positioning the detector.

[0016] As a further aspect of the present invention, the pressurization component includes: The main frame is fixedly installed inside the box. The second platform is slidably mounted on the main frame and is connected to the first motor drive. The third platform is slidably mounted on the second platform and is connected to the second motor drive; A lifting platform is slidably mounted on the third platform and is connected to a third motor drive. The mounting base includes a fixed base and a lifting base.

[0018] Compared with the prior art, the beneficial effects of the present invention are: This invention, by setting up a first moving platform and a cylinder, enables the automatic switching of the detector between the oiling station and the pressurization station, eliminating the need for manual handling and oiling / pressurization operations. It ensures that the oil volume and pressure of each chamber of the same batch of detectors are consistent. Furthermore, with the multi-station collaborative operation of the clamping components, the entire operation process does not require manual positioning assistance, enabling continuous operation of multiple chambers and multiple detectors, significantly improving production efficiency, while avoiding human operation errors and ensuring smooth process connections. This invention utilizes an instantaneous disengagement structure between the fastener and the bolt. Once the bolt is screwed into the oil injection hole to a preset depth, the fastener automatically disengages from the bolt. On one hand, it eliminates the need for electronic control and time-sharing of the fourth motor's speed and torque; the "clamping-feeding-automatic disengagement" can be achieved through pure mechanical linkage, reducing control complexity and improving equipment stability. On the other hand, it reduces continuous friction, compression, and collision between the fastener's sidewall and the bolt, slowing down wear and maintaining a clean and regular fastener surface. During the next bolt clamping, wear, debris, and deformation will prevent clamping eccentricity, ensuring higher alignment accuracy between the bolt and the oil injection hole each time, and avoiding hard contact, impacts, and misalignment.

Detailed Implementation

[0021] Please see Figures 1-18This invention provides a technical solution: a detector oil injection and pressurization device, including a base platform 1, a housing 2 on the base platform 1, a lifting door 3 on the housing 2, the lifting door 3 being driven to open or close by a lifting cylinder 30 installed on the housing 2, and also including an oil injection assembly 4, a first moving platform 5, a pressurization assembly 6, a bolt fastener 9, and a bolt supply assembly 10. The specific structure and connection relationship of each component are as follows: Oil injection component 4 (such as...) Figures 1-3 (as shown) The oil injection assembly 4 is fixedly installed on the base platform 1, located in front of the lifting door 3. It is used to inject oil into the oil injection chamber of the detector 100. The oil injection nozzle of the oil injection assembly 4 can be accurately aligned with the oil injection hole of the detector 100 to achieve complete filling of the chamber. After the oil injection is completed, it can be automatically removed to avoid interfering with the subsequent pressurization and sealing processes. The oil injection assembly 4 can adjust the oil injection flow rate and oil injection pressure according to the specifications of the detector 100 to ensure the oil injection effect.

[0022] First mobile platform 5 and drive mechanism (such as Figures 1-4 (as shown) The base platform 1 is provided with several parallel first slide rails 11. The first moving platform 5 is slidably mounted on the first slide rail 11 by a slider and can slide back and forth along the first slide rail 11 to realize the automatic switching of the detector 100 between the oil injection station and the pressurization station. The two ends of the first slide rail 11 are respectively provided with limit anti-collision seats 12 to limit the movement stroke of the first moving platform 5, avoid rigid collision with the base platform 1 or the housing 2, and protect the equipment components.

[0023] The driving mechanism is cylinder 13, which is horizontally installed on the base platform 1 between the base platform 1 and the side wall of the first moving platform 5. The first moving platform 5 is driven to move smoothly along the first slide rail 11 by the extension and retraction of cylinder 13.

[0024] The top of the first mobile platform 5 is provided with several clamping components 14. Each clamping component 14 consists of symmetrically arranged fixed plates 1401 and movable plates 1402. The fixed plates 1401 are fixedly connected to the first mobile platform 5, and the movable plates 1402 are fixedly connected to the clamping cylinder 15 and are driven to open or close by the clamping cylinder 15. When the clamping cylinder 15 extends or retracts, it drives the movable plates 1402 to move closer to or away from the detector 100, thereby realizing the rapid fixing and release of the detector 100. The bottom of the clamping component 14 is provided with a positioning base 16 for positioning the detector 100, and the top of the positioning base 16 is provided with a positioning groove that is adapted to the bottom of the detector 100.

[0025] Pressurization component 6 (such as Figures 2-6 (as shown) The pressurization assembly 6 is located inside the housing 2 and is used to pressurize the oil filling chamber of the detector 100. It includes a main frame 17, a second platform 18, a third platform 20, a lifting platform 22, a fixed base 24, and a lifting base 25. The specific structure is as follows: The main frame 17 is fixedly installed on the inner wall of the housing 2, serving as the installation base for the pressurization component 6. The second platform 18 is slidably installed on the main frame 17 via a slide rail slider. The main frame 17 is equipped with a first motor 19, whose output shaft is connected to the second platform 18 via a screw and nut mechanism (a common knowledge in the prior art, not specifically shown or described in the figure), for driving the second platform 18 to move horizontally (X-axis). The third platform 20 is slidably installed on the top of the second platform 18 via a slide rail slider. The second platform 18 is equipped with a second motor 21, whose output shaft is connected to the third platform 20 via a screw and nut mechanism, for driving the third platform 20 to move horizontally (Y-axis). The lifting platform 22 is slidably installed on one side of the third platform 20 via a slide rail slider. The third platform 20 is equipped with a third motor 23, whose output shaft is connected to the lifting platform 22 via a gear and rack mechanism, for driving the lifting platform 22 to move vertically (Z-axis).

[0026] The mounting base includes a fixed base 24 and a lifting base 25. The fixed base 24 is fixedly installed on one side of the bottom of the lifting platform 22, and the lifting base 25 is slidably installed on the fixed base 24. A cylinder 26 is provided between the lifting base 25 and the fixed base 24. The lifting base 25 is driven to rise and fall vertically along the fixed base 24 by the extension and retraction of the cylinder 26, so as to realize the height adjustment of the bolt fastener 9 and the cover plate 7.

[0027] A centralizer 28 is installed above the bolt retainer 9. The centralizer 28 is fixedly installed at the bottom of the fixed base 24 by bolts. It is used to center and straighten the bolt retainer 9 to prevent it from becoming eccentric when rotating or moving, and to ensure that the bolt is accurately aligned with the oil injection hole. A cover plate 7 is fixedly installed at the bottom of the centralizer 28. The bottom of the cover plate 7 is provided with a sealing layer 29. The sealing layer 29 is made of elastic silicone material. The cover plate 7 is a rigid planar structure to ensure that when the cover plate 7 is lowered, the sealing layer 29 can fully fit with the end of the detector 100 to form a sealed space and prevent pressure leakage during pressurization. Several pressure pipes 8 are provided on the cover plate 7 for pressurizing the oil injection chamber. A fourth motor 27 is installed on the lifting base 25. The fourth motor 27 is used to rotate the bolt retainer 9.

[0028] The work process is as follows: Equipment startup: Lifting cylinder 30 drives lifting door 3 to open, and the detector 100 is placed on positioning base 16 manually. Clamping cylinder 15 drives movable plate 1402 to close, clamping and fixing detector 100 between fixed plate 1401 and movable plate 1402. Oil filling operation: Cylinder 13 drives the first moving platform 5 to move along the first slide rail 11 (moving direction is below the oil filling component 4) to the oil filling station. The oil filling nozzle of the oil filling component 4 is aligned with the oil filling hole of the detector 100, and oil is injected into the chamber until it is completely filled. Workstation switching: After the oil injection is completed, cylinder 13 drives the first moving platform 5 to move in the opposite direction from the oil injection station to the pressurization station, and lifting cylinder 30 drives the lifting door 3 to close. Bolt removal: The first motor 19, the second motor 21, and the third motor 23 work together to drive the second platform 18, the third platform 20, and the lifting platform 22 to move, which in turn moves the bolt retainer 9 to the output port of the bolt supply assembly 10. The bolt retainer 9 then fixes the bolt and moves it thereafter. Pressurization and sealing: The first motor 19, the second motor 21, and the third motor 23 work together to drive the second platform 18, the third platform 20, and the lifting platform 22 to move, driving the fixed seat 24 and the lifting seat 25 to move directly above the detector 100. Then the lifting platform 22 descends inside the third platform 20, thereby causing the cover plate 7 to descend. The sealing layer 29 fits with the end of the detector 100 to form a sealed space. The pressurization pipe 8 is aligned with the oil injection hole of the first chamber to be pressurized, and a medium with a preset pressure is injected into the chamber. Bolt sealing: After pressurization, cylinder 26 drives the lifting seat 25 and bolt retainer 9 to descend. At the same time, the fourth motor 27 drives the bolt retainer 9 to rotate, screwing the bolt into the oil injection hole to achieve chamber sealing and pressure maintenance. During the tightening process, the bolt retainer 9 ensures accurate bolt positioning under the action of the straightener 28 to avoid misalignment. Cyclic operation: After the bolt sealing is completed, the pressurizing component 6 moves to the bolt supply component 10 to retrieve a new bolt, and repeats the steps of "pressurizing and sealing" - "bolt sealing" to complete the pressurization and sealing of all oil injection chambers of the detector 100 in sequence; Operation completed: After all chambers have been processed, lift door 3 is opened, clamping assembly 14 is released, and detector 100 is manually removed, completing a single operation.

[0029] This invention, by setting up a first moving platform 5 and a cylinder 13, enables the detector 100 to automatically switch between the oiling station and the pressurizing station, eliminating the need for manual handling and oiling / pressurizing operations. This ensures that the oil volume and pressure of each chamber of the same batch of detectors are consistent. Furthermore, with the multi-station collaborative operation of the clamping assembly 14, the entire operation process does not require manual positioning assistance, enabling continuous operation of multiple chambers and multiple detectors 100, significantly improving production efficiency, while avoiding human operation errors and ensuring smooth process connections.

[0030] The pressurization assembly 6 is driven by the first motor 19, the second motor 21, and the third motor 23 to achieve precise three-dimensional movement of the mounting base, ensuring accurate alignment of the cover plate 7 and the pressurization pipe 8. The cover plate 7 adopts a structure of rigid plane and elastic sealing layer 29, which, together with the centering and straightening effect of the centralizer 28, makes the sealing layer 29 fully and tightly fit with the end of the detector 100, forming a reliable sealed space, optimizing the pressurization and sealing effect, and ensuring stable pressure. The pressurization pipe 8 corresponds one-to-one with the oil injection chamber, realizing independent pressurization of a single chamber, ensuring uniform and stable pressurization, and improving the seismic wave transmission accuracy of the detector.

[0031] Bolt retainer 9 (e.g.) Figures 6-18 (as shown) The bolt fastener 9 includes a connecting sleeve 901, a rotating rod 9011, a contact element 902, and multiple positioning components.

[0032] The rotating rod 9011 is fixedly installed at the top of the connecting sleeve 901. The upper end of the rotating rod 9011 is fixedly connected to the output shaft of the fourth motor 27, which is used to drive the bolt retainer 9 to rotate, thereby tightening and loosening the bolt. The rotating rod 9011 is rotatably and slidably connected to the straightener 28. The contact member 902 is slidably connected to the bottom of the connecting sleeve 901. A spring 9014 is fixed between the contact member 902 and the connecting sleeve 901. Several positioning components are provided between the contact member 902 and the connecting sleeve 901. These positioning components are distributed in a ring at equal distances with the center point of the contact member 902 as the center.

[0033] Each positioning component includes a transition surface 903, a trigger component, and a release component, all formed on the connecting sleeve 901. The transition surface 903 gradually slopes upward from the bottom. A fixing component 904 is slidably connected to the contact component 902. A spring 9015 is fixed between the fixing component 904 and the contact component 902. The fixing component 904 contacts the transition surface 903. A locking component 905 is provided above the transition surface 903. A groove is formed on the locking component 905. A snap-fit ​​portion 9013 corresponding to the groove is provided on the contact component 902.

[0034] The trigger assembly includes a trigger rod 906 and a baffle 907; the trigger rod 906 is slidably connected to the connecting sleeve 901, and a spring 9016 is fixed between the trigger rod 906 and the connecting sleeve 901; the baffle 907 is rotatably mounted on the connecting sleeve 901, and a torsion spring 9017 is sleeved on the rotating shaft of the baffle 907; the trigger rod 906 is provided with an unlocking mechanism, which includes a limiting piece 908 and an arc-shaped piece 909; the limiting piece 908 is slidably connected to the connecting sleeve 901, and a spring 9018 is fixed between the limiting piece 908 and the connecting sleeve 901; the arc-shaped piece 909 is fixed to the side wall of the baffle 907; the unlocking mechanism is used to force the baffle 907 to rotate from vertical to tilt after the trigger rod 906 is compressed upward to a specified degree, thereby causing the fixing piece 904 to release instantaneously and elastically.

[0035] The release assembly is used to unlock the fixing member 904 from the locking member 905. It includes a lever 9010, which rotates on the connecting sleeve 901. A torsion spring 9019 is sleeved on the rotating shaft of the lever 9010. The locking member 905 is slidably connected to the connecting sleeve 901. A spring 9020 is fixed between the locking member 905 and the connecting sleeve 901. The top of the lever 9010 is located on one side of the locking member 905. During the process of the trigger rod 906 resetting from the top downward, it pushes the lever 9010 to rotate and pushes the locking member 905 away from the fixing member 904 through the top of the lever 9010, thereby unlocking the fixing member 904 from the locking member 905.

[0036] The bottom end of the contact element 902 is provided with several contact wheels 9012 for contacting the bolt head to reduce friction.

[0037] The working principle of bolt fastener 9 is as follows: Material extraction stage (e.g.) Figures 9-10 (as shown) When the bolt retainer 9 descends to the feeding position of the bolt supply assembly 10, the contact element 902 contacts the bolt and is then... Figure 9 As shown, it was pushed upwards to Figure 10 As shown, spring 9014 is compressed during this process.

[0038] The positioning and locking of contact 902 and connecting sleeve 901 during material handling (e.g.) Figures 9-10 (as shown) While maintaining contact with the transition surface 903, the fixing member 904 rises along with the contact member 902 and is guided by the transition surface 903, forcing the fixing member 904 to slide inward into the contact member 902 and compressing the spring 9015. During this process, the fixing member 904 moves closer to the bolt and clamps the bolt (e.g., ...). Figure 10 As shown, when the contact member 902 is about to slide to its limit, the locking part 9013 contacts the inclined surface at the bottom of the locking member 905, pushing the locking member 905 to slide away from the locking part 9013 along the connecting sleeve 901 and compressing the spring 9020; after the locking part 9013 at the end of the fixing member 904 aligns with the groove, the spring 9020 drives the locking member 905 to reset and engage with the locking part 9013, thus achieving locking; After the fixing member 904 and the contact member 9002 rise to their limit, the fixing member 904 contacts the side wall of the baffle 907, but the limiting piece 908 is sleeved on the baffle 907 and blocks it, so the baffle 907 cannot rotate.

[0039] Bolt transfer: The second platform 18, the third platform 20, and the lifting platform 22 work together to move the fixed base 24 directly above the detector 100, causing the cover plate 7 to descend until it contacts the top of the detector 100 to achieve a seal, facilitating subsequent pressurization; at this time, the bottom end of the trigger rod 906 descends to... Figure 11 The image shows the initial contact state with the inner top surface of the detector 100.

[0040] Bolt tightening: Cylinder 26 extends, causing the lifting seat 26 to descend along the fixed seat 24. During this process, the fourth motor 27 synchronously drives the rotating rod 9011 to rotate, causing the bolt to move into the bolt hole inside the detector 100 and be inserted, thus achieving tightening. Figure 13 As shown, a portion of the bolt (the dotted line portion) enters the bolt hole, and the trigger rod 906 is lifted from the initial horizontal dotted line P to the horizontal dotted line P2, which is higher than the horizontal dotted line P1 at the bottom of the limit piece 908; Unlock mechanism triggered: like Figure 14 As shown, when the trigger rod 906 moves from P to P2, its top end contacts the bottom of the limiting plate 908 and lifts it from P2 to the horizontal dotted line P3. After the limiting plate 908 disengages from the top end of the stop plate 907, the force exerted by the torsion spring 9017 on the stop plate 907 to keep it vertical is instantly broken by the spring 9015. At this time, the fixing member 904 will instantly push the stop plate 907 from the horizontal state to the horizontal position. Figure 14 When the device is tilted, the fastener 904 will disengage from the bolt, thereby releasing the fixation. Furthermore, the insertion end at the bottom of the limiting piece 908 (marked as A1 in the figure) will disengage from the insertion part between the limiting piece 908 and the arc-shaped piece 909 (marked as A2 in the figure).

[0041] It is important to note that: Figure 13 In the diagram, after the bolt is inserted into the bolt hole, there is a length L between the nut and the detector 100. However, in use, this L is an adjustable length. Although it is shown as slightly larger in the diagram, the length L can be shortened by moving the trigger rod 906 upward to the maximum distance.

[0042] Release component work (such as) Figures 16-18 (as shown) After the bolts are tightened, the lifting seat 25 rises, and the connecting sleeve 901 rises. During this process, the trigger rod 906 will descend from position P2 to position P under the action of the spring 9016. During the descent, it will descend to the middle position of the two arc-shaped parts 909. When the side wall of the trigger rod 906 descends to contact the lever 9010, it will press down on the bottom end of the lever 9010 and force it to rotate around the axis of rotation. Figure 18The state shown by the dotted line is rotated (during the upward movement of the trigger rod 906, the side wall will push the top of the lever 9010 to rotate to the right, but the lever 9019 will not be interfered with during the rotation, so the lever 9010 will automatically reset after the side wall of the trigger rod 906 disengages from the lever 9010). The torsion spring 9019 will also be compressed. When lever 9010 is rotated, its top end rotates to the left and pushes locking member 905 to slide along connecting sleeve 901 away from contact member 902 and compress spring five 9020. At this time, the groove will disengage from the locking part 9013 after moving away from the locking part 9013, and then contact member 902 will automatically reset under the action of spring one 9014.

[0043] However, the fixing member 904 pushes the baffle 907 into an inclined state, so the fixing member 904 is stuck in the notch inside the connecting sleeve 901. The contact member 902 will not slide immediately during the downward reset process, but the trigger rod 906 will descend. When the trigger rod 906 descends to contact the inclined baffle 907, it will force the baffle 907 to rotate vertically. At this time, the baffle 907 will force the fixing member 904 to slide inward along the contact member 902. When the baffle 907 rotates to vertical, it will push the fixing member 904 out completely. At this time, the contact member 902 can slide down smoothly. Then the arc-shaped member 909 also rotates to the initial state. Then the insertion part A2 follows the baffle 907 to rotate to the position directly below the insertion end A1. At this time, the limiting piece 908 is reset by the elastic tension of the spring 9018.

[0044] This invention utilizes a structure that allows the fixing member 904 to instantly disengage from the bolt. Once the bolt is screwed into the oil injection hole to a preset depth, the fixing member 904 automatically disengages from the bolt. On one hand, it eliminates the need for electronic control and time-sharing of the speed and torque of the fourth motor 27; the "clamping-feeding-automatic disengagement" can be achieved through pure mechanical linkage, reducing control difficulty and improving equipment stability. On the other hand, it reduces continuous friction, compression, and collision between the sidewall of the fixing member 904 and the bolt, slowing down the wear of the fixing member 904 and maintaining its surface neatness and cleanliness. During the next bolt clamping, wear, debris accumulation, and deformation will prevent clamping eccentricity, ensuring higher alignment accuracy between the bolt and the oil injection hole each time, and avoiding hard contact, impacts, and misalignment.

[0045] Meanwhile, after the fastener 904 is disengaged, the fourth motor 27 can continue to rotate. It relies solely on the contact wheel 9012 at the bottom of the contact element 902 to maintain rolling contact with the top of the bolt and follow the rotation. Rolling friction replaces sliding friction, significantly reducing wear at the contact position, protecting the flatness of the top of the bolt and the bottom of the contact element 902, and preventing the bolt from deviating due to unevenness or tilting of the contact surface after long-term use. This further improves the coaxiality and sealing reliability of repeated alignment and tightening, and extends the service life of the entire machine.

[0046] The bolt supply assembly 10 is fixedly installed inside the housing 2, located on one side of the pressure assembly 6, and is used to supply bolts to be installed to the bolt fastener 9. The bolt supply assembly 10 has bolt straightening, defect rejection and bolt supply functions (common knowledge in the prior art, which will not be described in detail here), and is used for the orderly delivery of bolts. At the same time, it is equipped with a vision capture system to detect the posture and appearance of the bolts, realize the straightening of bolts and the rejection of defective bolts (such as thread damage, head chipping) to ensure that all supplied bolts are qualified products.
