Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery manufacturing, in particular to a perpendicularity detection tool. BACKGROUND

[0002] With the development of new energy technology, batteries are increasingly widely used, such as in mobile phones, notebook computers, electric cars, electric vehicles, electric aircraft, electric ships, electric toy cars, electric toy ships, electric tools, etc. The core of battery performance lies in the manufacturing quality of battery monomers.

[0003] In the process of manufacturing battery monomers, stress and strain tests are generally performed on related materials by a tensile testing machine. The perpendicularity of the chuck of the tensile testing machine has a great influence on the material testing. Therefore, it is crucial to develop a tool for detecting the perpendicularity of the chuck of the tensile testing machine. CONTENT OF THE UTILITY MODEL

[0004] The main purpose of the present application is to provide a perpendicularity detection tool, which aims to inspect the perpendicularity of the chuck of the tensile testing machine through the detection tool.

[0005] To solve the above problems, the present application provides a perpendicularity detection tool, which comprises a fixing assembly and a positioning plate. The fixing assembly comprises a support part, a connecting part and a clamping part. The connecting part is arranged on the support part in a lifting manner. The support part is configured to support the connecting part. The clamping part is connected with the connecting part and is configured to clamp and fix the connecting part on the column of the tensile testing machine. The positioning plate is connected with the connecting part and is configured to be clamped in the chuck of the tensile testing machine for perpendicularity detection of the chuck. Thus, the positioning plate in the perpendicularity detection tool can be clamped in the chuck of the tensile testing machine as a high-precision "reference gauge" to detect the perpendicularity of the chuck of the tensile testing machine, which helps to improve the accuracy of adjustment. By adjusting the height of the connecting part, the detection tool can be flexibly adapted to the initial height of the chuck of different models of tensile testing machines, which can effectively improve the versatility of the detection tool. The clamping part can be mechanically locked through clamping action, so that the detection tool remains stable and positioned during the testing process, reducing the measurement deviation caused by loosening. Moreover, the clamping structure can adapt to different sizes of columns, improving the versatility of the detection tool.

[0006] In some embodiments, the support part comprises a support rod, and the support rod is threadedly connected with the connecting part. Thus, the screw transmission can convert the rotary motion into precise linear fine adjustment, thereby helping the operator to finely and controllably adjust the height of the connecting part and the positioning plate. At the same time, the self-locking property of the threaded connection helps to maintain the position stable after adjustment, reduces the possibility of introducing errors due to accidental displacement during detection, and enhances the operation stability and measurement reliability of the detection tool. In addition, this lifting structure is simple, easy to process and assemble, and also helps to control the manufacturing cost.

[0007] In some embodiments, the support rod comprises a first sub-support rod and a second sub-support rod arranged at intervals, the first sub-support rod is threadedly connected with one end of the connecting part, and the second sub-support rod is threadedly connected with the other end of the connecting part. In this way, the double-sub-support rod structure can significantly improve the stability of the entire detection tooling, and provide a stable reference for the positioning plate. In addition, the operator can independently fine-tune the screwing depth of any sub-support rod, so as to finely calibrate the levelness of the connecting part and the positioning plate.

[0008] In some embodiments, the clamping part comprises a first clamping plate and a second clamping plate arranged oppositely, one end of the first clamping plate is provided with a first sliding block, and one end of the second clamping plate is provided with a second sliding block; the connecting part is provided with a first sliding rail and a second sliding rail arranged at intervals, the first sliding block is slidably connected with the first sliding rail, and the second sliding block is slidably connected with the second sliding rail, and the extension directions of the first sliding rail and the second sliding rail are parallel to the interval directions of the first clamping plate and the second clamping plate. In this way, the first clamping plate and the second clamping plate can move towards or away from each other along the defined track under the driving of external force, so as to realize stepless and smooth adjustment of the opening size of the clamping part, and enhance the adaptability of the detection tooling to the columns of the pull tester with different diameters and the flexibility of clamping. Moreover, clamping from both sides of the column can reduce or avoid the deflection of the connecting part caused by unilateral force or asymmetric clamping, and improve the reliability of the detection tooling.

[0009] In some embodiments, the clamping part further comprises a threaded rod, the threaded rod comprises a first threaded segment and a second threaded segment with opposite rotation directions, the first clamping plate is threadedly connected with the first threaded segment, and the second clamping plate is threadedly connected with the second threaded segment. In this way, the two clamping plates on both sides can be driven to move towards or away from each other synchronously through the design of the threaded segments with opposite rotation directions. In this way, the efficiency and convenience of the clamping operation can be significantly improved, and the symmetry and uniformity of the clamping force can be improved. At the same time, the threaded transmission itself has self-locking characteristics, which helps to maintain the clamping state after adjustment is completed.

[0010] In some embodiments, the clamping part further comprises a handle, the handle is connected with one end of the threaded rod. In this way, the handle can provide an application point for the operator, so that the operation of rotating the threaded rod and driving the clamping plate to move becomes more labor-saving and convenient, and in this way, the clamping efficiency can be effectively improved.

[0011] In some embodiments, one end of the first sliding rail is provided with a first limiting piece, and the other end of the first sliding rail is provided with a second limiting piece; one end of the second sliding rail is provided with a third limiting piece, and the other end of the second sliding rail is provided with a fourth limiting piece. Thus, the limiting pieces can effectively limit the movement range of the sliding block on the sliding rail, thereby preventing the first clamping plate and the second clamping plate from accidentally slipping off the sliding rail during adjustment, and enhancing the safety and reliability during operation; at the same time, the limiting pieces define the physical movement limit of the sliding block, which helps the operator to more quickly and intuitively determine the adjustment range of the clamping part, thereby improving the convenience and efficiency of operation.

[0012] In some embodiments, the connecting part includes a limiting plate and a handle, the limiting plate is connected with the positioning plate, the first sliding rail and the second sliding rail are arranged at one end of the limiting plate, and the handle is arranged at the other end of the limiting plate. Thus, the limiting plate cooperates with the handle to finely adjust the left and right distance of the positioning plate and move it to the limiting position of the chuck of the tensile testing machine, so that the detection tool is compatible with different clamping surface locking positions.

[0013] In some embodiments, the first clamping plate is provided with a first pressing plate on the side close to the second clamping plate; and the second clamping plate is provided with a second pressing plate on the side close to the first clamping plate. Thus, the first pressing plate and the second pressing plate can effectively bear the concentrated stress and friction generated during clamping, thereby significantly reducing the wear of the clamping plate body, protecting the key structure and prolonging the overall service life of the detection tool.

[0014] In some embodiments, the first pressing plate is provided with a first contact pad on the side away from the first clamping plate, and the friction coefficient of the first contact pad is greater than that of the first pressing plate; and the second pressing plate is provided with a second contact pad on the side away from the second clamping plate, and the friction coefficient of the second contact pad is greater than that of the second pressing plate. Thus, the contact pad with high friction coefficient can greatly increase the static friction force between the clamping part and the surface of the column of the tensile testing machine, thereby effectively inhibiting the relative sliding or slight displacement of the tool during detection, and providing stronger clamping stability and reliability for the entire measurement system.

[0015] In some embodiments, the clamping part further includes a first elastic shaft and a second elastic shaft, one end of the first elastic shaft is connected with the first clamping plate, the other end of the first elastic shaft is connected with the first pressing plate, one end of the second elastic shaft is connected with the second clamping plate, and the other end of the second elastic shaft is connected with the second pressing plate. Thus, the elastic shaft can form a flexible buffer, which can be slightly elastically deformed under external force; this feature enables the first pressing plate and the second pressing plate to have a certain self-adaptive adjustment capability during clamping. Moreover, the flexible connection structure can also absorb and attenuate slight vibrations or impacts that may occur during operation, which helps to maintain the stability of the measurement state, thereby providing a reliable reference for the perpendicularity detection.

[0016] In some embodiments, the extension direction of the positioning plate is parallel to the spacing direction of the upper chuck and the lower chuck of the tensile testing machine, one end of the positioning plate extends towards one side of the connecting portion, the one end of the positioning plate is configured to perform perpendicularity detection on the upper chuck of the tensile testing machine, the other end of the positioning plate extends towards the other side of the connecting portion, and the other end of the positioning plate is configured to perform perpendicularity detection on the lower chuck of the tensile testing machine. Thus, this structure allows the operator to use the two ends of the positioning plate as a reference after fixing the detection tool once, and then sequentially detects the upper chuck and the lower chuck of the tensile testing machine, without repeatedly disassembling, adjusting and installing the detection tool, which can significantly improve the detection efficiency and reduce the reference error that may be introduced due to repeated disassembly. In addition, this design allows the perpendicularity detection of the upper and lower chucks to be based on the same positioning plate, thereby enhancing the reliability of the detection results and helping to more accurately judge the perpendicularity of the chucks.

[0036] From the current market development trend, the application range of the battery is continuously expanding, not only widely used in water, fire, wind and solar power station and other energy storage power supply systems, but also widely used in electric bicycles, electric motorcycles, electric vehicles and other transportation tools, as well as aerospace and other fields. With the continuous expansion of application scenarios, the market demand for batteries continues to grow, and higher requirements are put forward for the quality of batteries.

[0037] In battery manufacturing, the battery cell as a basic unit of the battery system directly affects the overall performance of the battery device. Even if there is a small defect in a single battery cell, it is often amplified in a series-parallel connection structure, thereby causing the output efficiency of the entire battery system device to decrease and the cycle life to shorten.

[0038] Therefore, in the process of battery cell production, monitoring of key process links is particularly important. For example, in material stress-strain testing, the perpendicularity of the clamping head of the commonly used tension testing machine has a significant impact on the accuracy of the test results. In order to improve the consistency and reliability of the test results of the tension testing machine, developing a special tool for detecting the perpendicularity of the clamping head of the tension testing machine has become one of the important links to improve production quality.

[0039] Based on this, the perpendicularity detection tool provided in the present application includes a fixing assembly and a positioning plate, the positioning plate is connected with the fixing assembly, the fixing assembly is configured to support the positioning plate, and the positioning plate is configured to be clamped in the clamping head of the tension testing machine to detect the perpendicularity of the clamping head. The detection tool can be used to detect the perpendicularity of the clamping head of the tension testing machine, the positioning plate of the detection tool can be clamped in the clamping head of the tension testing machine, so that the axis deflection of the clamping head can be converted into a measurable deviation on the side of the positioning plate, thereby providing a quantitative basis for the perpendicularity adjustment of the clamping head, which helps to improve the accuracy of the perpendicularity adjustment of the clamping head.

[0040] The battery device mentioned in the embodiments of the present application can include one or more battery cells, and the plurality of battery cells are connected in series, in parallel or in a hybrid connection through a bus member. The hybrid connection means that there are both series and parallel connections among the plurality of battery cells.

[0041] The battery cell described in the embodiments of the present application refers to a rechargeable battery or a disposable battery. Disposable batteries are also called "throwaway" batteries and primary batteries because they cannot be recharged for use after their power is depleted and can only be discarded. Rechargeable batteries are also called secondary batteries or secondary cells, storage batteries. The manufacturing materials and processes of rechargeable batteries are different from those of primary batteries, and the characteristic is that they can be used repeatedly after being charged. The output current load of the rechargeable battery is higher than that of most disposable batteries.

[0042] The battery cell can include but is not limited to a lithium ion battery cell, a sodium ion battery cell, a sodium-lithium ion battery cell, a lithium metal battery cell, a sodium metal battery cell, a lithium-sulfur battery cell, a magnesium ion battery cell, a nickel-hydrogen battery cell, a nickel-cadmium battery cell, a lead-acid battery cell, etc.

[0043] Optionally, the battery cell can be a cylindrical battery cell, a prismatic battery cell, or a battery cell of other shapes. Prismatic battery cells include prismatic battery cells, blade-shaped battery cells, and multi-prismatic batteries, such as hexagonal prismatic batteries.

[0045] For ease of explanation, the following embodiments use a vehicle as an example of electrical equipment.

[0046] like Figure 1 As shown, Figure 1 These are schematic diagrams of the vehicle structure provided in some embodiments of this application.

[0047] Vehicle 1 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. A battery device 2 is installed inside vehicle 1, and the battery device 2 can be located at the bottom, front, or rear of vehicle 1. The battery device 2 can be used to power vehicle 1; for example, it can serve as the operating power source for vehicle 1. Vehicle 1 may also include a controller 3 and a motor 4. The controller 3 controls the battery device 2 to supply power to the motor 4, for example, to meet the power needs of vehicle 1 during starting, navigation, and driving.

[0048] In some embodiments of this application, the battery device 2 can not only serve as the operating power source for the vehicle 1, but also as the driving power source for the vehicle 1, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1.

[0049] like Figure 2 As shown, Figure 2 This is an exploded structural diagram of a battery device provided in some embodiments of this application.

[0050] The box 5 is used to accommodate the battery cell 6, and the box 5 can be of various structures. In some embodiments, the box 5 can include a first box part 51 and a second box part 52, the first box part 51 and the second box part 52 are mutually covered, and the first box part 51 and the second box part 52 jointly define an accommodation space for accommodating the battery cell 6. The first box part 51 can be a hollow structure with one end open, and the second box part 52 is a plate-shaped structure, which is covered on the open side of the first box part 51 to form the box 5 with the accommodation space; the first box part 51 and the second box part 52 can also be hollow structures with one side open, and the open side of the first box part 51 is covered on the open side of the second box part 52 to form the box 5 with the accommodation space. Of course, the first box part 51 and the second box part 52 can be of various shapes, such as a cylinder, a cuboid, etc.

[0051] In the battery device 2, the battery cell 6 can be one or multiple. If the battery cell 6 is multiple, the multiple battery cells 6 can be connected in series, in parallel or in a mixed manner, and the mixed manner means that the multiple battery cells 6 are connected in series and in parallel. The multiple battery cells 6 can be directly connected in series, in parallel or in a mixed manner, and then the whole of the multiple battery cells 6 is accommodated in the box 5; of course, the multiple battery cells 6 can be first connected in series, in parallel or in a mixed manner to form a battery module, and then the multiple battery modules are connected in series, in parallel or in a mixed manner to form a whole, which is accommodated in the box 5.

[0052] The battery cell 6 can be the smallest unit constituting the battery device 2. As shown in Figure 3 Figure 3 is a schematic diagram of the exploded structure of the battery cell provided in some embodiments of the present application.

[0053] As shown in Figure 3 , the battery cell 6 includes a housing 40 and an electrode assembly 61 accommodated in the housing 40.

[0054] The housing 40 is used to package the electrode assembly 61 and other components such as electrolyte. The housing 40 can be a steel shell, an aluminum shell, a plastic shell (such as polypropylene), a composite metal shell (such as a copper-aluminum composite shell) or an aluminum-plastic film, etc. The electrolyte plays a role of conducting ions between the positive and negative electrodes. The electrolyte can be liquid, gel or solid.

[0055] ​In some embodiments, the housing 40 includes a shell 20 and an end cover 30, the shell 20 having an opening. The shell 20 is a component for fitting the end cover 30 to form an internal environment of the battery cell 6, wherein the formed internal environment can be used to accommodate the electrode assembly 61, the electrolyte, and other components. The end cover 30 refers to a component that is capped at the opening of the shell 20 to insulate the internal environment of the battery cell 6 from the external environment. Without limitation, the shape of the end cover 30 can be adapted to the shape of the shell 20 to fit the shell 20. Alternatively, the end cover 30 can be made of a material with certain hardness and strength (such as aluminum alloy), so that the end cover 30 is less likely to deform when subjected to extrusion collision, allowing the battery cell 6 to have higher structural strength. The end cover 30 can be provided with functional components such as the electrode terminal 25. The electrode terminal 25 can be used to electrically connect with the electrode assembly 61 for outputting or inputting the electrical energy of the battery cell 6.

[0056] The electrode assembly 61 is a component in which electrochemical reactions occur in the battery cell 6. One or more electrode assemblies 61 can be contained in the shell 20. The electrode assembly 61 is mainly formed by winding or stacking a positive electrode sheet and a negative electrode sheet, and generally has a separator provided between the positive electrode sheet and the negative electrode sheet. The positive electrode sheet and the negative electrode sheet have portions with active materials constituting a main body of the electrode assembly 61, and portions without active materials each constituting a tab. The positive electrode tab and the negative electrode tab can be located together at one end of the main body or at two ends of the main body, respectively.

[0057] In some embodiments, the positive electrode sheet, the negative electrode sheet, and the separator arranged in a stack can be wound to form a cylindrical body, and the cylindrical body can be rolled to form the electrode assembly 61 with the intermediate flat sides bent.

[0058] In the process of producing the battery cell 6, tests on the elongation, adhesion, and the like of materials can be involved. The test materials can include sheet coating, separators, and current collectors (aluminum foil / copper foil), and the like. In the related art, the stress-strain behavior of the test materials is generally tested by a tensile testing machine, and the perpendicularity of the clamping head of the tensile testing machine has a great influence on the test of the materials. In order to reduce the test error of the tensile testing machine and improve the displacement measurement accuracy of the equipment, embodiments of the present application provide a perpendicularity detection tool.

[0059] Please refer to Figure 4 shown in the drawings, Figure 4 is a structural schematic diagram of a perpendicularity detection tool and a tensile testing machine provided by some embodiments of the present application.

[0060] The tensile testing machine 70 includes a clamping head 71 and a column 72 for fixing the clamping head 71, and the column 72 is generally a single column structure.

[0061] The perpendicularity detection tool 100 (hereinafter referred to as "detection tool 100") includes a fixing assembly 10 and a positioning plate 13, the positioning plate 13 is connected with the fixing assembly 10, the fixing assembly 10 is configured to support the positioning plate 13, and the positioning plate 13 is configured to be clamped in the chuck 71 of the tensile testing machine 70 to detect the perpendicularity of the chuck 71.

[0062] The positioning plate 13 is designed to be clamped in the chuck 71 of the tensile testing machine 70. When the detection tool 100 measures the perpendicularity of the chuck 71 of the tensile testing machine 70, the height of the positioning plate 13 is adjusted to match the height of the chuck 71, and the positioning plate 13 is placed in the chuck 71, so that the chuck 71 clamps the two ends of the positioning plate 13, thereby detecting and adjusting the perpendicularity of the chuck 71.

[0063] In the above embodiment, the positioning plate 13 can be used as a high-precision "reference gauge", which is clamped in the chuck 71 of the tensile testing machine 70 to detect the perpendicularity of the chuck 71 of the tensile testing machine 70. In this way, the abstract axis deflection of the chuck 71 can be converted into a measurable deviation on the side of the positioning plate 13, thereby providing a quantitative basis for the perpendicularity adjustment of the chuck 71, which helps to improve the accuracy of the adjustment of the chuck 71.

[0064] In some embodiments, as shown in Figure 1 The fixing assembly 10 can include a support part 11 and a connecting part 12. The connecting part 12 is connected with the support part 11, and the support part 11 is configured to support the connecting part 12. The connecting part 12 is arranged on the support part 11 in a lifting manner, and the positioning plate 13 is connected with the connecting part 12.

[0065] The connecting part 12 and the support part 11 can form a stable frame, which helps to reduce the influence of external interference and thus reduce the introduction of secondary errors. The support part 11 is used to provide stable support for the connecting part 12. The connecting part 12 and the support part 11 can have adjustable vertical displacement capability. The connecting part 12 can be lifted relative to the support part 11. The lifting connection structure of the connecting part 12 and the support part 11 can be set in multiple ways. For example, the lifting structure can adopt the way of rotating the support part 11 and adjusting the screw. Alternatively, the lifting structure can be realized by a sliding rail guide structure.

[0066] By setting the liftable connecting part 12, the height of the connecting part 12 can be flexibly adjusted, thereby adjusting the height of the positioning plate 13, so that the detection tool 100 can match the initial height of the chuck 71 of the pull tester 70 of different specifications and models, and the calibration reference surface can be kept flush with the working surface of the chuck 71, thereby effectively improving the universality of the detection tool 100 and reducing the number of special detection tools 100. Moreover, the lifting function of the connecting part 12 allows the operator to quickly adjust the positioning plate 13 to the optimal detection starting position, without the need to repeatedly move the support part 11, thereby significantly simplifying the operation process and improving the detection efficiency.

[0067] In some embodiments, the support part 11 comprises a support rod 101, which is threadedly connected with the connecting part 12.

[0068] The threaded connection of the support rod 101 and the connecting part 12 can realize the height adjustment function. The support rod 101 can be made of metal materials such as stainless steel or aluminum alloy, etc. The thread structure can be a standard metric thread or a self-tapping thread. The connecting part 12 can comprise a threaded hole or a nut structure matched with the support rod 101. By rotating the support rod 101, the extension length thereof can be changed, thereby adjusting the relative height of the positioning plate 13 and the chuck 71. The threaded connection of the support rod 101 and the connecting part 12 can adopt a stop washer to enhance the stability and prevent loosening during use.

[0069] The support rod 101 connected by threads can accurately control the vertical distance between the positioning plate 13 and the clamping surface of the chuck 71. This adjustable structure can adapt to the height difference of the chucks 71 of different models of pull testers 70, and reduce the occurrence of measurement deviation caused by height mismatch. The rigid support of the threaded connection can effectively reduce the vibration transmission during detection, and improve the detection stability of the perpendicularity of the chuck 71. At the same time, this structure is convenient to disassemble and reuse, reduces the maintenance cost of the detection tool 100, and prolongs the service life of the detection tool 100. The threaded transmission can convert the rotary motion into precise linear fine adjustment, thereby helping the operator to finely and controllably lift the height of the connecting part 12 and the positioning plate 13, improving the adjustment accuracy and convenience. At the same time, the self-locking property of the threaded connection helps to maintain the position stable after adjustment. In addition, the threaded connection structure is simple, easy to process and assemble, and also helps to control the manufacturing cost of the detection tool 100.

[0070] In other embodiments, the support rod 101 can also be in the structure of a telescopic rod, which can comprise two sub-telescopic rods connected in a nested manner, and the height of the connecting part 12 is adjusted by the telescopic movement of one of the sub-telescopic rods. In this way, the height of the positioning plate 13 can also be adjusted.

[0071] In some embodiments, as shown in FIG. 6, the support part 11 can comprise a support rod 101, which is connected with the connecting part 12 by a threaded connection. Figure 1As shown, the support rod 101 can include a first sub-support rod 111 and a second sub-support rod 112 arranged at intervals, the first sub-support rod 111 being threadedly connected to one end of the connecting portion 12, and the second sub-support rod 112 being threadedly connected to the other end of the connecting portion 12.

[0072] The first sub-support rod 111 and the second sub-support rod 112 are respectively connected to the two ends of the connecting portion 12 by threadedly connecting. This structural design enables the two sub-support rods to adjust the height of the positioning plate 13 by rotation, thereby adapting to the needs of the collet 71 of different heights.

[0073] The above structural design enables accurate adjustment of the height of the positioning plate 13 by rotating the first sub-support rod 111 and the second sub-support rod 112 at both ends. The interval arrangement of the first sub-support rod 111 and the second sub-support rod 112 makes the support points more reasonable, so as to improve the stability of the detection tool 100, and provide a stable reference for the positioning plate 13. In addition, the operator can independently fine-tune the rotation depth of any sub-support rod, so as to accurately calibrate the levelness of the connecting portion 12 and the positioning plate 13.

[0074] It can be understood that in other embodiments, the support rod 101 can also include three sub-support rods arranged at intervals, and the three sub-support rods are respectively connected to the two ends and the middle position of the connecting portion 12 to support the connecting portion 12 at three points. In other embodiments, the support rod 101 can also be provided with more than 3 sub-support rods.

[0075] As shown, Figure 5 As shown, Figure 5 is a structural schematic diagram of a verticality detection tool and a tension machine provided by some embodiments of the present application. The support portion 11 can further include a clamping portion 102, and the connecting portion 12 is connected to the clamping portion 102, and the clamping portion 102 is configured to clamp and fix the connecting portion 12 on the column 72 of the tension machine 70.

[0076] The support portion 11 includes the clamping portion 102, which is designed to fix the connecting portion 12 on the column 72 of the tension machine 70, and is realized by mechanical locking through clamping action. Optionally, various ways such as clamping plate, buckle type structure or elastic clamping can be used to realize the clamping function.

[0077] Through the reliable fixation of the clamping portion 102 and the column 72 of the tension machine 70, the detection tool 100 can be stably positioned during the test. By connecting the clamping structure with the column 72 of the tension machine 70, the detection tool 100 can be adapted to columns 72 of different sizes, thereby improving the versatility of the detection tool 100. Further, the cooperation with the buffer material during clamping can reduce the wear on the surface of the column 72.

[0078] AsFigure 6 、 Figure 7 and Figure 8 as shown in Figure 6 is a structural schematic diagram of a verticality detection tool provided by some embodiments of the present application; Figure 7 is a side structural schematic diagram of the verticality detection tool shown in Figure 6 ; Figure 8 is a top structural schematic diagram of the verticality detection tool shown in Figure 6 .

[0079] The clamping portion 102 can include a first clamping plate 113 and a second clamping plate 114 arranged opposite to each other. As shown in Figure 7 , one end of the first clamping plate 113 is provided with a first sliding block 115, and one end of the second clamping plate 114 is provided with a second sliding block 116; the connecting portion 12 is provided with a first sliding rail 117 and a second sliding rail 118 arranged at intervals, and the first sliding block 115 is in sliding connection with the first sliding rail 117, and the second sliding block 116 is in sliding connection with the second sliding rail 118. The extension direction of the first sliding rail 117 and the second sliding rail 118 is parallel to the interval direction of the first clamping plate 113 and the second clamping plate 114.

[0080] In the above embodiments, the clamping portion 102 includes the first clamping plate 113 and the second clamping plate 114 arranged opposite to each other, and the first clamping plate 113 and the second clamping plate 114 are moved towards or away from each other through the sliding rail and the sliding block. Through the sliding cooperation structure of the sliding block and the sliding rail, the interval between the first clamping plate 113 and the second clamping plate 114 can be accurately adjusted. In this way, the clamping portion 102 can adapt to column bodies 72 of different sizes. That is, the first clamping plate 113 and the second clamping plate 114 can be driven by external force to move towards or away from each other along the defined sliding rail synchronously, so that stepless and smooth adjustment of the opening size of the clamping portion 102 can be realized, and the adaptability and flexibility of the detection tool 100 to column bodies 72 of different diameter tension machines 70 can be enhanced. The sliding block slides to clamp the column body 72 by the first clamping plate 113 and the second clamping plate 114, and then the position of the sliding block is locked, so that the clamping force of the clamping portion 102 can be maintained.

[0081] The parallel sliding rails can increase the straightness of the movement track of the first clamping plate 113 and the second clamping plate 114, and reduce the positioning deviation caused by inclination. Moreover, the guiding effect of the sliding rails can reduce the shaking of the first clamping plate 113 and the second clamping plate 114 during movement, enhance the clamping stability, and thus improve the accuracy of verticality calibration. In addition, by clamping the column body 72 of the tension machine 70 from both sides by the first clamping plate 113 and the second clamping plate 114, the deflection of the connecting portion 12 caused by unilateral force or asymmetric clamping can be reduced or avoided, and the reliability of the detection tool 100 can be improved.

[0082] In some embodiments, as Figure 7As shown, the clamping portion 102 further comprises a threaded rod 119, which comprises a first threaded segment 1191 and a second threaded segment 1192 with opposite rotation directions. The first clamping plate 113 is threadedly connected with the first threaded segment 1191, and the second clamping plate 114 is threadedly connected with the second threaded segment 1192.

[0083] The threaded rod 119 comprises two threaded segments with opposite rotation directions, and the first clamping plate 113 and the second clamping plate 114 can be synchronously driven to move in opposite directions by rotating the threaded rod 119, so as to adjust the clamping force. The threaded rod can be made of metal, and the rotation directions of the first threaded segment 1191 and the second threaded segment 1192 are right-handed and left-handed respectively. When the column 72 with different widths needs to be clamped, the number of rotation of the threaded rod 119 can be adjusted to match the size of the column 72.

[0084] In the above embodiment, the synchronous reverse movement of the first clamping plate 113 and the second clamping plate 114 can be realized by the threaded segments with opposite rotation directions, so that the clamping process is more stable and reliable. This structure can accurately control the clamping distance and adapt to the structure of the column 72 of the tension machine 70 with different sizes. The rotation adjustment mode of the threaded rod 119 makes the detection operation more convenient and reduces the manual adjustment time. At the same time, this transmission structure also has a self-locking feature, which can maintain a stable state after adjustment to fix the positions of the first clamping plate 113 and the second clamping plate 114 and maintain the clamping force of the first clamping plate 113 and the second clamping plate 114.

[0085] In some embodiments, as shown in Figs. 1A and 1B, the clamping portion 102 further comprises a handle 1193 connected with one end of the threaded rod 119. Figure 7 and Figure 8 As shown, the clamping portion 102 further comprises a handle 1193 connected with one end of the threaded rod 119.

[0086] The handle 1193 is provided on the clamping portion 102 for the operator to hold, and is connected with one end of the threaded rod 119 to transmit the rotation force. The handle 1193 can be made of metal or engineering plastic, and its shape can be L-shaped or straight rod-shaped, etc. The threaded rod 119 drives the first clamping plate 113 and the second clamping plate 114 to move by rotation, and the handle 1193 is provided to facilitate manual adjustment of the clamping force.

[0087] The connection between the handle 1193 and the threaded rod 119 can be threaded connection, clamping or integrally formed, etc. When the clamping distance between the first clamping plate 113 and the second clamping plate 114 needs to be adjusted, the operator rotates the handle 1193 to rotate the threaded rod 119, thereby driving the first clamping plate 113 and the second clamping plate 114 to move towards or away from each other, so as to realize clamping or loosening of the column 72 of the tension machine 70. The handle 1193 is also provided to amplify the operating force through the lever principle, thereby reducing the manual strength required for adjustment.

[0088] By setting the linkage structure of the handle 1193 and the threaded rod 119, the convenience of adjusting the clamping part 102 can be significantly improved. The operator can complete the adjustment of the clamping force without the aid of additional tools, reducing the manual operation time and effectively improving the clamping efficiency.

[0089] In some embodiments, as shown in Figure 7 , one end of the first sliding rail 117 is provided with a first limiting piece 103, and the other end of the first sliding rail 117 is provided with a second limiting piece 104; one end of the second sliding rail 118 is provided with a third limiting piece 105, and the other end of the second sliding rail 118 is provided with a fourth limiting piece 106.

[0090] The first sliding rail 117 is provided with a first limiting piece 103 and a second limiting piece 104 at both ends respectively for limiting the movement range of the first sliding block 115, and the second sliding rail 118 is provided with a third limiting piece 105 and a fourth limiting piece 106 at both ends respectively for limiting the movement range of the second sliding block 116. Figure 7 In the embodiment shown in , the limiting pieces are in the form of mechanical stoppers, which limit the movement stroke of the sliding block through physical contact. When the sliding block moves on the sliding rail, the limiting piece prevents the sliding block from leaving the track or exceeding the predetermined working range.

[0091] In other embodiments, the limiting piece can also be in the form of a photoelectric sensor to limit the movement stroke of the sliding block through signal feedback.

[0092] By setting the multi-point limiting structure, the movement range of the sliding block on the sliding rail can be effectively limited, thereby preventing the first clamping plate 113 and the second clamping plate 114 from accidentally slipping off the sliding rail during adjustment, enhancing the safety and reliability during operation. At the same time, the limiting piece defines the physical movement limit of the sliding block, which helps the operator to quickly and intuitively determine the adjustment range of the clamping part 102, thereby improving the convenience and efficiency of operation.

[0093] Figure 6 and Figure 7As shown, the connecting portion 12 can include a limiting plate 121 and a handle 122. The first slide rail 117 and the second slide rail 118 are arranged at one end of the limiting plate 121, and the handle 122 is arranged at the other end of the limiting plate 121.

[0094] The limiting plate 121 is used to support the first slide rail 117 and the second slide rail 118. The handle 122 is arranged at the end of the limiting plate 121, which is convenient for the operator to hold and apply force. The first slide rail 117 and the second slide rail 118 are arranged along the length direction of the limiting plate 121. When the first clamping plate 113 and the second clamping plate 114 clamp and fix the column 72, the limiting plate 121 can be moved along the slide rail by operating the handle 122, so as to drive the positioning plate 13 to slide in the horizontal direction for adjustment.

[0095] In the above embodiment, by integrating the slide rail structure in the limiting plate 121 and cooperating with the handle 122 design, flexible adjustment of the positioning plate 13 in the horizontal direction can be realized, so as to adapt to the perpendicularity detection of the chuck 71 at different positions. That is, the limiting plate 121 cooperates with the handle design, which can fine-tune the left and right distance of the positioning plate 13 to the limiting position of the chuck 71 of the tensile testing machine 70, so that the detection tool 100 is compatible with different chuck locking positions.

[0096] In some embodiments, as shown, Figure 7 The first clamping plate 113 is provided with a first pressing plate 1131 on the side close to the second clamping plate 114, and the second clamping plate 114 is provided with a second pressing plate 1141 on the side close to the first clamping plate 113.

[0097] When the first clamping plate 113 and the second clamping plate 114 are arranged oppositely, the first pressing plate 1131 and the second pressing plate 1141 are arranged on the clamping surfaces respectively. Thus, the first pressing plate 1131 and the second pressing plate 1141 can act as force receiving components that act on the column 72 of the tensile testing machine 70, and can effectively bear the concentrated stress and friction generated during clamping, thereby significantly reducing the wear on the clamping plate body, protecting the key structure and prolonging the overall service life of the detection tool 100.

[0098] In some embodiments, the first pressing plate 1131 is provided with a first contact pad 1132 on the side away from the first clamping plate 113, and the friction coefficient of the first contact pad 1132 is greater than that of the first pressing plate 1131. The second pressing plate 1141 is provided with a second contact pad 1142 on the side away from the second clamping plate 114, and the friction coefficient of the second contact pad 1142 is greater than that of the second pressing plate 1141.

[0099] Both the clamping surfaces of the first pressure plate 1131 and the second pressure plate 1141 are provided with contact pads, the material of which is chosen to have a higher coefficient of friction than the pressure plate body. This design increases the friction of the clamping surfaces and improves the stability of the inspection fixture 100. The contact pads can be made of high-friction materials such as silicone, rubber, or engineering plastics. Optionally, the contact pads can be fixed to the pressure plate surface by adhesive, embedding, or snap-fit. For example, double-sided tape can be used to adhere a silicone pad to the clamping surface of the pressure plate. The first contact pad 1132 and the second contact pad 1142 can have the same shape and material to improve the uniformity of force on both sides.

[0100] Optionally, raised textures or grooves may be provided on the surfaces of the first contact pad 1132 and the second contact pad 1142 to further enhance friction.

[0101] In the above embodiments, by providing a contact pad with a high coefficient of friction on the surface of the pressure plate, the static friction between the clamping part 102 and the column 72 of the tensile testing machine 70 can be significantly improved. This design achieves stable positioning under relatively small clamping forces, thereby effectively suppressing relative sliding or slight displacement that may occur in the testing fixture 100 during the testing process, providing stronger clamping stability and reliability for the entire measurement system. Simultaneously, this structure reduces dependence on clamping forces, reduces component wear caused by uneven pressure during long-term use, and extends the service life of the testing fixture 100. The elastic properties of the contact pad can also compensate for minor deformations of the clamping surface, improving the adaptability and reliability of the testing process.

[0102] In some embodiments, such as Figure 7 As shown, the clamping part 102 may further include a first elastic shaft 1133 and a second elastic shaft 1143. One end of the first elastic shaft 1133 is connected to the first clamping plate 113, and the other end of the first elastic shaft 1133 is connected to the first pressure plate 1131. One end of the second elastic shaft 1143 is connected to the second clamping plate 114, and the other end of the second elastic shaft 1143 is connected to the second pressure plate 1141.

[0103] The first elastic shaft 1133 and the second elastic shaft 1143 can be made of elastic materials such as helical springs or rubber. The structure of the elastic shafts allows for elastic deformation between the clamping plate and the pressure plate. When the pressure plate contacts the column 72 of the tensioning machine 70, the elastic shafts will undergo compression or bending deformation. This deformation can absorb and offset part of the clamping force, or absorb and offset the impact caused by slight vibration of the column 72. This provides cushioning for the rigid contact of "hard against hard".

[0104] Therefore, through the setting of the elastic shaft, it can be elastically deformed slightly under external force, so as to form a flexible buffer between the first pressing plate 1131, the second pressing plate 1141 and the corresponding clamping plate. This feature enables the first pressing plate 1131 and the second pressing plate 1141 to have a certain self-adaptive adjustment capability during clamping. Moreover, the flexible connection structure can also absorb or attenuate slight vibration or impact that may occur during operation, which helps to maintain the stability of the measurement state, thereby providing a reliable reference for the perpendicularity detection.

[0105] In some embodiments, referring to FIGS. 1 and 2, the extension direction of the positioning plate 13 is parallel to the spacing direction of the upper chuck 711 and the lower chuck 712 of the tensile testing machine 70. One end of the positioning plate 13 extends towards one side of the connecting portion 12, and is configured to detect the perpendicularity of the upper chuck 711 of the tensile testing machine 70. The other end of the positioning plate 13 extends towards the other side of the connecting portion 12, and is configured to detect the perpendicularity of the lower chuck 712 of the tensile testing machine 70. Figure 5 Figure 8 In some embodiments, referring to FIGS. 1 and 2, the extension direction of the positioning plate 13 is parallel to the spacing direction of the upper chuck 711 and the lower chuck 712 of the tensile testing machine 70. One end of the positioning plate 13 extends towards one side of the connecting portion 12, and is configured to detect the perpendicularity of the upper chuck 711 of the tensile testing machine 70. The other end of the positioning plate 13 extends towards the other side of the connecting portion 12, and is configured to detect the perpendicularity of the lower chuck 712 of the tensile testing machine 70.

[0106] In some embodiments, referring to FIGS. 1 and 2, the extension direction of the positioning plate 13 is parallel to the spacing direction of the upper chuck 711 and the lower chuck 712 of the tensile testing machine 70. One end of the positioning plate 13 extends towards one side of the connecting portion 12, and is configured to detect the perpendicularity of the upper chuck 711 of the tensile testing machine 70. The other end of the positioning plate 13 extends towards the other side of the connecting portion 12, and is configured to detect the perpendicularity of the lower chuck 712 of the tensile testing machine 70.

[0107] In some embodiments, referring to FIGS. 1 and 2, the extension direction of the positioning plate 13 is parallel to the spacing direction of the upper chuck 711 and the lower chuck 712 of the tensile testing machine 70. One end of the positioning plate 13 extends towards one side of the connecting portion 12, and is configured to detect the perpendicularity of the upper chuck 711 of the tensile testing machine 70. The other end of the positioning plate 13 extends towards the other side of the connecting portion 12, and is configured to detect the perpendicularity of the lower chuck 712 of the tensile testing machine 70.

[0108] ​In some embodiments, the positioning plate 13 can be arranged to extend towards one side of the connecting portion 12. In this way, the positioning plate 13 is protruded from one side of the connecting portion 12. In this way, the positioning plate 13 can be used to detect the verticality of the upper clamp head 711 and the lower clamp head 712 of the tensile testing machine 70 respectively. In this way, the detection tool 100 has a simple structure and a small size, and can be used to detect the verticality of a single clamp head 71.

[0109] Please refer to Figure 6 、 Figure 7 and Figure 8 In some embodiments, one end of the limiting plate 121 of the detection tool 100 is threadedly connected with the first sub-supporting rod 111, and the other end of the limiting plate 121 is threadedly connected with the second sub-supporting rod 112. The first sub-supporting rod 111 and the second sub-supporting rod 112 are used to support the connecting portion 12 on the table plane. Rotating the first sub-supporting rod 111 and the second sub-supporting rod 112 can adjust the height of the connecting portion 12, so that the height of the positioning plate 13 matches the height of the clamp head 71 of the tensile testing machine 70. The number of rotations of the first sub-supporting rod 111 and the second sub-supporting rod 112 can be consistent to ensure that the elongation is consistent. In this way, the detection tool 100 can be compatible with clamp heads 71 of different heights, and the versatility of the detection tool 100 is improved.

[0110] The detection tool 100 further comprises a clamping portion 102, which is used to be clamped on the column 72 of the tensile testing machine 70 to fix the detection tool 100 from the side. The clamping portion 102 comprises a first clamping plate 113 and a second clamping plate 114 arranged oppositely. One end of the first clamping plate 113 is provided with a first sliding block 115, and one end of the second clamping plate 114 is provided with a second sliding block 116. The limiting plate 121 is provided with a first sliding rail 117 and a second sliding rail 118 arranged at intervals. The first sliding block 115 is slidably connected with the first sliding rail 117, and the second sliding block 116 is slidably connected with the second sliding rail 118. The first clamping plate 113 and the second clamping plate 114 can move relatively under the drive of the first sliding block 115 and the second sliding block 116. The positioning plate 13 can be fine-tuned to the limiting position of the clamp head 71 of the tensile testing machine 70 through the sliding block structure.

[0111] Further, the clamping part 102 further comprises a threaded rod 119, the threaded rod 119 is provided with a first threaded section 1191 and a second threaded section 1192 in opposite rotation. The first clamping plate 113 is threadedly connected with the first threaded section 1191, and the second clamping plate 114 is threadedly connected with the second threaded section 1192. One end of the threaded rod 119 is provided with a handle 1193, and the clamping distance between the first clamping plate 113 and the second clamping plate 114 can be adjusted by operating the handle 1193. In this way, the clamping part 102 can be compatible with different widths of the column 72. By using a bidirectional adjusting threaded rod 119, when the rotation is locked to the width consistent with the column 72, at most one more rotation can be avoided or reduced to avoid or reduce damage to the column 72 of the tensile testing machine 70 due to excessive clamping.

[0112] The side of the first clamping plate 113 close to the second clamping plate 114 is provided with a first elastic shaft 1133, a first pressing plate 1131 and a first contact pad 1132 in sequence, one end of the first elastic shaft 1133 is connected with the first clamping plate 113, the other end of the first elastic shaft 1133 is connected with the first pressing plate 1131, and the side of the first pressing plate 1131 away from the first elastic shaft 1133 is provided with the first contact pad 1132. One end of the second elastic shaft 1143 is connected with the second clamping plate 114, the other end of the second elastic shaft 1143 is connected with the second pressing plate 1141, and the side of the second pressing plate 1141 away from the second elastic shaft 1143 is provided with the second contact pad 1142. The first contact pad 1132 and the second contact pad 1142 can be rubber pads, and by designing rubber pads on the surface of the pressing plate, the friction coefficient of the clamping surface can be increased, so that the pressing plate can limit the relative position of the clamping part 102 and the column 72 of the tensile testing machine 70 under a smaller normal pressure.

[0113] When the detection tool 100 of the above embodiment detects the perpendicularity of the chuck 71 of the tensile testing machine 70, the positioning plate 13 is supported on the table plane by the first sub-supporting rod 111 and the second sub-supporting rod 112. The height of the positioning plate 13 can be adjusted by rotating the first sub-supporting rod 111 and the second sub-supporting rod 112, so that the height of the positioning plate 13 matches the height of the chuck 71. Then, the handle 1193 is operated, and the clamping part 102 is clamped on the column 72 of the tensile testing machine 70, so as to fix the detection tool 100. The positioning plate 13 is fine-tuned in the horizontal direction by moving the connecting part 12, so that the positioning plate 13 can be located in the chuck 71. Then, the perpendicularity of the chuck 71 is detected by the positioning plate 13.

[0114] In summary, the detection tool 100 of the above embodiment can detect the perpendicularity of the chuck 71 of the puller 70. The positioning plate 13 in the detection tool 100 can be clamped in the chuck 71 of the puller 70 as a high-precision "reference gauge" to detect the perpendicularity of the chuck 71 of the puller 70. In this way, the abstract axis deflection of the chuck 71 can be converted into measurable deflection on the side of the positioning plate 13, thereby providing a quantitative basis for the perpendicularity adjustment of the chuck 71.
