Description

Technical Field

[0001] This utility model relates to the field of monitoring and detection technology, and in particular to a torque value monitoring device for a preset torque wrench. Background Technology

[0002] Torque wrenches are widely used in various industries as tools for tightening bolt torque during processing, production, and assembly. The accuracy of torque wrenches ensures the quality of high-quality products. Therefore, torque wrenches need to be tested during the production process to ensure their accuracy.

[0003] Existing torque wrench torque value monitoring devices typically use a torque tester to detect the torque value of the torque wrench in order to ensure its subsequent use.

[0004] However, when using a torque tester to monitor the torque value of torque wrenches of different sizes, it can only detect the torque value of the torque wrench, but cannot simultaneously record the torque value generated when the torque wrench rotates at an angle. At the same time, the horizontal support frame cannot be adjusted according to the size of the torque wrench.

[0005] Furthermore, existing torque testers only monitor the vertical tilt angle on a single axis, ignoring the critical influence of the horizontal torque component on the second peak; the angle sensor is not linked to the support structure, and cannot dynamically capture the offset during free loading after leveling; resulting in systematic errors in the torque value of the second peak due to angle deviation. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a torque value monitoring device for a preset torque wrench, which solves the problems of poor installation adaptability, single data dimension and large human error in traditional torque wrench testing, and significantly improves testing efficiency, accuracy and engineering practical value.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: a torque value monitoring device for a preset torque wrench, comprising a worktable and a torque wrench body. A torque sensor for monitoring the torque of the torque wrench body is fixedly installed at the top of the worktable. A support device for supporting the torque wrench body is provided at the top of the worktable. An adjustment device for driving the support device to move left and right is provided inside the worktable. A monitoring fixing device for monitoring the torque of the torque wrench body is provided at the top of the worktable. The adjustment device includes a moving component for supporting the support device at the top of the worktable. A driving component for driving the moving component to move left and right is provided inside the worktable. The support device includes a support plate for supporting the torque wrench body above the moving component. A height adjustment component for adjusting the height of the support plate is fixedly installed at the top of the moving component. The monitoring fixing device includes a monitoring component for monitoring the torque of the torque wrench body at the top of the worktable. A fixing component for detecting the angle of the torque wrench body is provided on the torque wrench body, and the fixing component and the monitoring component are electrically connected.

[0008] In addition, the torque value monitoring device for a preset torque wrench proposed in this application may also have the following additional technical features:

[0009] Specifically, the top of the workbench has a long slot for placing the drive assembly, and the bottom of the workbench is fixedly equipped with four support legs for supporting the workbench.

[0010] Specifically, the drive assembly includes a threaded rod disposed in a long slot for driving the moving assembly to move left and right, and a handwheel for driving the threaded rod to rotate is fixedly installed at the right end of the threaded rod.

[0011] Specifically, the movable component includes a threaded sleeve plate disposed in a long slot for threaded connection with a threaded rod, and a fixing plate for supporting the support device is fixedly installed at the top of the threaded sleeve plate.

[0012] Specifically, the height adjustment assembly includes four support columns fixedly installed on the top of the fixed plate, and the column body of each support column has several locking holes.

[0013] Specifically, the support column is provided with a connecting column for vertical movement, and a limiting plate is fixedly installed at the bottom end of the connecting column to prevent the connecting column from moving out of the support column. A locking rod is provided in the cavity of the locking hole to fix the limiting plate in the support column.

[0014] Specifically, the monitoring component includes a torque meter fixedly mounted on the top of the workbench for connection with a torque sensor via a wire, and a display screen fixedly mounted on the top of the workbench for connection with the torque meter.

[0015] Specifically, the fixing component includes two fixing rings fitted onto the torque plate body. An angle sensor for monitoring the angle of the torque plate body is fixedly installed at the top of the upper fixing ring, and the angle sensor is connected to a torque meter. A bolt for fixing the two fixing rings to the torque plate body is provided between the two fixing rings.

[0016] The beneficial effect of this utility model is that it solves the defects existing in the background technology.

[0017] 1. Multi-dimensional adjustment enhances applicability and accuracy: The drive component (threaded rod + handwheel) moves the moving component left and right, combined with the height-adjustable support device (support column + locking hole + connecting column), to achieve flexible adaptation of the torque wrench body in horizontal position and support height, ensuring that wrenches of different specifications always remain horizontal during testing, eliminating measurement errors caused by installation misalignment.

[0018] 2.

[0019] 3. Intelligent identification of slippage characteristics and loading process: The monitoring method uses the angle sensor to zero and level calibration, and combines the algorithm to automatically calculate derived parameters such as slippage margin angle, total torque angle, and torque loading rate. It accurately identifies the wrench's disengagement mechanism, quantitatively evaluates its working stability and reliability, and breaks through the limitation of traditional methods that only monitor peak torque.

[0020] 4. Improved ease of operation and efficiency: The support plate can be retracted to a non-supported state to avoid interfering with the loading process; the handwheel-driven threaded rod enables quick positioning, and the locking hole structure simplifies the height adjustment process; measurement data is uploaded to the display screen in real time and automatically generates curve reports, significantly reducing manual recording and calculation time.

[0021] 5. High structural integration and strong stability: The workbench is equipped with an adjustment device, and the support legs provide a stable base; the moving components (threaded sleeve plate + fixed plate) are rigidly connected to the support device to ensure no displacement or shaking during loading and to guarantee high repeatability test accuracy.

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0032] like Figures 1-8As shown, an embodiment of the present invention discloses a torque value monitoring device and method for a preset torque wrench, which may include a workbench 100 and a torque wrench body 600. A torque sensor 200 for monitoring the torque of the torque wrench body 600 is fixedly installed at the top of the workbench 100. A support device 400 for supporting the torque wrench body 600 is provided at the top of the workbench 100. An adjustment device 300 for driving the support device 400 to move left and right is provided inside the workbench 100. A monitoring fixing device 500 for monitoring the torque of the torque wrench body 600 is provided at the top of the workbench 100. The adjustment device 300 includes a device disposed at the top of the workbench 100 for adjusting the torque of the support device 400. The moving component 320 provides support. The worktable 100 is equipped with a drive component 310 for driving the moving component 320 to move left and right. The support device 400 includes a support plate 410 disposed above the moving component 320 for supporting the torque plate body 600. A height adjustment component 420 for adjusting the height of the support plate 410 is fixedly installed at the top of the moving component 320. The monitoring and fixing device 500 includes a monitoring component 510 disposed at the top of the worktable 100 for monitoring the torque of the torque plate body 600. A fixing component 520 for monitoring the angle of the torque plate body 600 is disposed on the torque plate body 600, and the fixing component 520 and the monitoring component 510 are electrically connected.

[0033] In one embodiment of this utility model, such as Figure 2 As shown, the top of the worktable 100 has a long slot 101 for placing the drive assembly 310, and the bottom of the worktable 100 is fixedly equipped with four support legs 102 for supporting the worktable 100. The four support legs 102 are welded to the bottom of the worktable 100 in a rectangular array, so the worktable 100 can be easily supported by the four support legs 102. The torque sensor 200 is used to detect the torsional torque on various rotating or non-rotating mechanical parts. Therefore, the torque sensor 200 can be used to monitor the torque of the torque plate body 600 in real time.

[0034] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the drive assembly 310 includes a threaded rod 311 disposed in the elongated slot 101 for driving the moving assembly 320 to move left and right, and the left and right ends of the threaded rod 311 are connected by bearings, thus facilitating the rotation of the threaded rod 311; a handwheel 312 for driving the rotation of the threaded rod 311 is fixedly installed on the right end of the threaded rod 311.

[0035] Furthermore, the movable component 320 includes a threaded sleeve 321 disposed within the elongated groove 101 for threaded connection with the threaded rod 311. The shape and size of the threaded sleeve 321 are the same as those of the elongated groove 101. Therefore, when the threaded rod 311 rotates, the threaded sleeve 321 can always move left and right along the threaded rod 311, thus allowing for rapid adjustment according to the length of the torque wrench body 600. A fixed plate 322 for supporting the support device 400 is fixedly mounted on the top of the threaded sleeve 321. Thus, when it is necessary to support the torque wrench body 600 according to its dimensions, the threaded rod 311 can be rotated by the handwheel 312, and the threaded sleeve 321 can move left and right along the threaded rod 311. Therefore, the support device 400 on the fixed plate 322 can adjust the distance between the torque wrench body 600 and the torque sensor 200.

[0036] In one embodiment of this utility model, such as Figure 3 , Figure 4 and Figure 5 As shown, the height adjustment assembly 420 includes four support columns 421 fixedly installed on the top of the fixed plate 322. The four support columns 421 are welded to the top of the fixed plate 322 in a rectangular array. The internal cavity of the support column 421 is stepped. Several locking holes 422 are provided on the column body of the support column 421. The locking holes 422 are distributed in a linear array on the column body of the support column 421.

[0037] Furthermore, a connecting column 423 for vertical movement is provided inside the support column 421. A limiting plate 424 for preventing the connecting column 423 from moving out of the support column 421 is fixedly installed at the bottom end of the connecting column 423. A locking rod 425 for fixing the limiting plate 424 inside the support column 421 is provided in the cavity of the locking hole 422. Thus, when it is necessary for the torque plate body 600 on the torque sensor 200 to remain horizontal, a tool can be used to embed the force-receiving head of the torque plate body 600 into the force-receiving square groove of the torque sensor 200; and then the limiting plate 424 is used to fix the connecting column 421. The support plate 410 on the connecting column 423 can be adjusted up and down by moving the plate 410 up and down within the column 421. The locking rod 425 passes through the locking hole 422, which can fix the limiting plate 424 in the support column 421. Therefore, the torque plate body 600 on the torque sensor 200 can be kept horizontal. The threaded rod 311 can be rotated by the handwheel 312, and the threaded sleeve 321 can move left and right along the threaded rod 311. Therefore, the support device 400 on the fixed plate 322 can adjust the distance between the torque plate body 600 and the torque sensor 200.

[0038] In one embodiment of this utility model, such as Figure 6 and Figure 7As shown, the monitoring component 510 includes a torque meter 511 fixedly installed on the top of the workbench 100 for connection with the torque sensor 200 via a wire. The torque meter 511 is model HBF2-200 and uses a high-precision AD converter. The torque meter 511, model HBF2-200, has a measurement range of 2-200 Nm and an accuracy of 0.3 grade. It has two ranges: 2Nm-20Nm and 20Nm-200Nm. A display screen 512 is fixedly installed on the top of the workbench 100 for connection with the torque meter 511. The display screen 512 is a large-size color display instrument with built-in touch function that collects real-time torque test signals, uploads the collected data to a computer for data processing, plots real-time loading curves, and analyzes loading characteristics. The display screen 512 has an expandable channel and an interface for connecting to a computer to upload data.

[0039] Furthermore, the fixing component 520 includes two fixing rings 522 fitted onto the torque plate body 600, which are symmetrically distributed vertically on the torque plate body 600. An angle sensor 521 for monitoring the angle of the torque plate body 600 is fixedly installed at the top of the upper fixing ring 522, and the angle sensor 521 is connected to the torque meter 511. The angle measurement range of the angle sensor 521 is 0-180 degrees, with an accuracy of 0.05 degrees. A bolt 523 is provided between the two fixing rings 522 to fix them onto the torque plate body 600. Therefore, the bolt 523 can be used to pass through the two fixing rings 522 to install the angle sensor 521 on the torque plate body 600, allowing for real-time angle monitoring as the torque plate body 600 rotates.

[0040] In one embodiment of this utility model, such as Figure 8 As shown, a method for monitoring the torque value of a preset torque wrench is disclosed. This monitoring method is applicable to torque wrench torque value monitoring devices and is performed by the following method:

[0041] S1: The torque plate body 600 to be measured is placed on the output head of the torque sensor 200, and the force-receiving head of the tool is embedded in the force-receiving square groove of the torque sensor 200, so that the lever arm of the torque plate body 600 acts on the support plate 410 of the worktable 100, keeping the torque plate body 600 horizontal; then the limiting plate 424 moves up and down in the support column 421 to control the up and down adjustment of the support plate 410 on the connecting column 423; then the locking rod 425 passes through the locking hole 422 to fix the limiting plate 424 in the support column 421; thus, the torque plate body 600 on the torque sensor 200 can be kept horizontal; then the handwheel 312 drives the threaded rod 311 to rotate, and the threaded sleeve 321 can move left and right along the threaded rod 311, so that the support device 400 on the fixed plate 322 can adjust the distance between the torque plate body 600 and the torque sensor 200.

[0042] S2: Fit the two retaining rings 522 onto the torque plate body 600, and use bolts 523 to fix the two retaining rings 522 onto the torque plate body 600, so that the zeroing key of the torque instrument 511 is zeroed; the measurement mode of the torque instrument 511 is selected as needed to either the tracking mode or the holding mode; then the data recorded by the angle sensor 521 is displayed on the display screen 512 to keep the torque plate body 600 horizontal.

[0043] S3: Gradually increase the angle of the torque plate body 600, and the torque meter 511 will display the torque output value and angle of the torque plate body 600 in real time and upload the data to the display screen 512.

[0044] S4: When the applied torque reaches the preset value, the torque plate body 600 will jump off, stop loading, and record the test data through the display screen 512.

[0045] In summary, this utility model provides a torque value monitoring device for a preset torque wrench. When torque value monitoring of torque wrench bodies 600 of different sizes is required, the torque wrench body 600 to be measured is placed on the output head of the torque sensor 200, and the force-receiving head of the tool is embedded in the force-receiving square groove of the torque sensor 200, so that the lever arm of the torque wrench body 600 acts on the support plate 410 of the workbench 100, keeping the torque wrench body 600 horizontal; then, the limiting plate 424 moves up and down within the support column 421. The movement controls the up-and-down adjustment of the support plate 410 on the connecting column 423; then, by passing the locking rod 425 through the locking hole 422, the limiting plate 424 can be fixed in the support column 421; thus, the torque plate body 600 on the torque sensor 200 can be kept horizontal; then, by driving the threaded rod 311 to rotate through the handwheel 312, the threaded sleeve 321 can move left and right along the threaded rod 311, thus allowing the support device 400 on the fixed plate 322 to adjust the distance between the torque plate body 600 and the torque sensor 200; An angle sensor 521 is mounted on the torque plate body 600 using bolts 523 that pass through two fixing rings 522, allowing for real-time angle monitoring of the torque plate body 600. The torque plate body 600 is then gradually subjected to angular force, and the torque meter 511 displays the torque output value and angle of the torque plate body 600 in real time, uploading the data to the display screen 512. When the applied torque reaches a preset value, the torque plate body 600 detaches, stopping the loading, and the test data is recorded on the display screen 512. Therefore, the torque plate can be identified. The difference between the verified value and the actual usage value of the 600 rated torque of the sub-body determines the accuracy of the torque indication, which is suitable for providing user selection advice; through repeated training of different operators with different loading techniques and forces, the loading rate is controlled as much as possible to minimize the impact of the "second peak" on the torque value, ensuring accurate torque loading, which is suitable for pre-job training of enterprise operators; by measuring the slip margin angle, the cause and solution of the "second peak" are found, ensuring the consistency between the torque verification value and the actual usage value to the greatest extent possible, which is suitable for improving product design and enhancing product quality.
