Description
Technical Field
[0001] This utility model relates to the technical field of torque detection devices, and in particular to an automatic adjusting arm clamp torque detection device. Background Technology
[0002] In numerous fields such as machinery manufacturing, automotive industry, and aerospace, automatic adjusting arms are key components, and their performance directly affects the safety and reliability of the system. The clamping torque, as a core parameter for the assembly and performance of the automatic adjusting arm, is therefore crucial for accurate measurement.
[0003] Currently, traditional methods for detecting torque in automatic adjusting arm clamps largely rely on manual operation and simple tools. When using a torque wrench manually, factors such as the operator's application angle, force control, and fatigue level lead to significant data dispersion, making it difficult to guarantee the consistency and accuracy of the results. Furthermore, manual testing is extremely inefficient, failing to meet the demands of large-scale production and severely hindering production progress.
[0004] To address the aforementioned problems, we propose an automatic adjustment arm clamp torque detection device. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic adjustment arm clamp torque detection device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automatic adjustment arm clamp torque detection device includes a detection platform, on which a clamp placement mechanism and a testing mechanism are provided; the testing mechanism includes a slide, a fixed base is fixedly installed on the upper side of the slide, a servo motor is fixedly installed on the upper side of the fixed base, a drive shaft is fixedly installed on the output end of the servo motor, a first stabilizing bushing, a dynamic torque sensor and a second stabilizing bushing are sequentially screwed onto the upper side of the slide, the drive shaft rotates through the first stabilizing bushing, a test shaft is rotatably installed on the dynamic torque sensor, and an output shaft is rotatably installed inside the second stabilizing bushing.
[0008] Furthermore, a first coupling is fitted between the test shaft and the drive shaft, and a second coupling is fitted between the test shaft and the output shaft.
[0009] By adopting the above technical solution, the first coupling and the second coupling are set up to connect the two ends of the test shaft on the dynamic torque sensor to the transmission shaft and the output shaft respectively, which facilitates dynamic monitoring of torque.
[0010] Furthermore, a dovetail groove is fixedly installed on the upper side of the testing platform, and a dovetail block is fixedly connected to the bottom of the slide block, with the dovetail block slidably installed inside the dovetail groove.
[0011] Furthermore, a side plate is fixedly installed on the back of the testing platform, and an electric push rod is fixedly installed on the side plate. The output end of the electric push rod is fixedly connected to the slide.
[0012] By adopting the above technical solution, when the electric push rod is started, it can drive the entire testing mechanism to slide on the testing table. When testing, it can drive the output shaft at the front end of the testing mechanism to be inserted into the drive shaft hole of the adjusting arm fixture.
[0013] Furthermore, a support base is fixedly installed on the side of the testing platform, and a controller is fixedly installed on the support base.
[0014] Furthermore, columns are symmetrically fixedly installed on the upper side of the testing platform, and crossbeams are fixedly installed on the upper side of the columns.
[0015] By adopting the above technical solution, the controller is used to control the coordinated operation of various electrical components in the device, thereby improving detection efficiency.
[0016] Furthermore, a liquid crystal display is fixedly installed on the upper side of the crossbeam.
[0017] Furthermore, the fixture placement mechanism includes a base, which is fixedly installed on the upper side of the testing platform. A vertical rod is fixedly installed on the upper side of the base, and an adjusting arm fixture is slidably sleeved on the outer side of the vertical rod.
[0018] By adopting the above technical solution, when the adjustment arm clamp is installed at the test point, it only needs to be slidably sleeved on the vertical rod and its drive shaft hole aligned with the output shaft. Since the output shaft applies a torsional force to its drive shaft hole, it will not slip off the vertical rod, and its installation and fixing process is relatively convenient and quick.
[0019] Furthermore, the side of the adjusting arm clamp is provided with a drive shaft hole, which is adapted to the cross-sectional dimensions of the output shaft.
[0020] Furthermore, a pressing ring is pressed onto the upper side of the adjusting arm clamp, the pressing ring is slidably sleeved on the outside of the vertical rod, and several counterweight crossbars are fixedly connected at equal intervals around the outer circumference of the pressing ring.
[0021] By adopting the above technical solution, the counterweight bar increases the weight pressed against the upper side of the adjusting arm clamp, making the fixing of the adjusting arm clamp more stable. At the same time, the counterweight bar can be used as a handle to facilitate pulling out the pressing ring upwards.
[0022] Compared with related technologies, the automatic adjustment arm clamp torque detection device proposed in this utility model has the following beneficial effects:
[0023] In this invention, an automatic adjustment arm clamp torque detection device is described. Through a testing mechanism, the two ends of the test shaft on the dynamic torque sensor are connected to the transmission shaft and output shaft respectively via a first coupling and a second coupling. This places the dynamic torque sensor within the entire output force transmission system. The dynamic torque sensor can monitor the output torque in real time. Compared to traditional static torque sensors, it offers real-time monitoring and fast data response. Furthermore, under the control of the controller, it can directly transmit the dynamic torque data graph to an LCD screen for display. Testing personnel can monitor the testing process in real time by observing the data curve. After testing, the data curve can be analyzed to assess the torque transmission response of the adjustment arm clamp. The testing process is fast, highly automated, and the test results are clear and reliable, thus improving testing efficiency. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0031] Reference Figures 1-5 An automatic adjustment arm clamp torque detection device includes a detection platform 1, on which a clamp placement mechanism 7 and a testing mechanism 9 are provided. The testing mechanism 9 includes a slide 91, a fixed seat 93 fixedly installed on the upper side of the slide 91, a servo motor 94 fixedly installed on the upper side of the fixed seat 93, a drive shaft 95 fixedly installed on the output end of the servo motor 94, a first stabilizing bushing 96, a dynamic torque sensor 97 and a second stabilizing bushing 910 sequentially screwed onto the upper side of the slide 91, the drive shaft 95 rotatably passing through the first stabilizing bushing 96, a test shaft 98 rotatably installed on the dynamic torque sensor 97, an output shaft 911 rotatably installed inside the second stabilizing bushing 910, a first coupling 99 sleeved between the test shaft 98 and the drive shaft 95, and a second coupling 912 sleeved between the test shaft 98 and the output shaft 911.
[0032] In this embodiment, the fixture placement mechanism 7 includes a base 71, which is fixedly installed on the upper side of the testing table 1. A vertical rod 72 is fixedly installed on the upper side of the base 71. An adjusting arm fixture 73 is slidably sleeved on the outer side of the vertical rod 72. A drive shaft hole 74 is provided on the side of the adjusting arm fixture 73. The drive shaft hole 74 is adapted to the cross-sectional dimensions of the output shaft 911. A pressing ring 75 is pressed onto the upper side of the adjusting arm fixture 73. The pressing ring 75 is slidably sleeved on the outer side of the vertical rod 72. Several counterweight crossbars 76 are fixedly connected at equal intervals around the outer circumference of the pressing ring 75.
[0033] With the above structure, the output shaft 911 is inserted into the inner side of the drive shaft hole 74. When it rotates, it can apply output torque to the adjusting arm clamp 73. According to the action and reaction of force, the reaction force of the torque borne by the adjusting arm clamp 7 is equal to the output torque of the output shaft 911. Then, the torque information obtained by the dynamic torque sensor 97 is equal to the torque reaction force inside the adjusting arm clamp 73. Observe the dynamic curve of the torque. If the dynamic curve fluctuates greatly, it indicates that the reaction force inside the adjusting arm clamp 73 is unstable and fluctuates greatly. Therefore, the torque transmission of the adjusting arm clamp 73 is not stable enough in actual use, and the test result of the adjusting arm clamp 73 is unqualified.
[0034] In this embodiment, a dovetail groove 8 is fixedly installed on the upper side of the testing platform 1, and a dovetail block 92 is fixedly connected to the bottom of the slide 91. The dovetail block 92 is slidably installed inside the dovetail groove 8. A side plate 10 is fixedly installed on the back of the testing platform 1, and an electric push rod 11 is fixedly installed on the side plate 10. The output end of the electric push rod 11 is fixedly connected to the slide 91.
[0035] With the above structure, after the electric push rod 11 is started, it can drive the test mechanism 9 to slide on the test table 1 to change the relative position of the output shaft 911 and the drive shaft hole 74 on the side of the adjusting arm fixture 73. During the test, the output shaft 911 is inserted into the inside of the drive shaft hole 74. After the test is completed, the output shaft 911 is pulled out of the drive shaft hole 74 to facilitate the replacement of the next adjusting arm fixture 73 to be tested.
[0036] In this embodiment, a support base 2 is fixedly installed on the side of the detection table 1, and a controller 3 is fixedly installed on the support base 2.
[0037] Through the above structure, controller 3 controls the electrical components to work together, thereby improving detection efficiency.
[0038] In this embodiment, columns 4 are symmetrically fixedly installed on the upper side of the testing platform 1, crossbeams 5 are fixedly installed on the upper side of the columns 4, and liquid crystal displays 6 are fixedly installed on the upper side of the crossbeams 5.
[0039] With the above structure, the liquid crystal display 6 is used to display a real-time dynamic graph of torque during the detection process.
[0040] In this utility model, during use:
[0041] Fixture Placement: The operator places the automatic adjusting arm fixture 73 to be tested on the fixture placement mechanism 7. Specifically, the adjusting arm fixture 73 is slidably sleeved on the outside of the vertical rod 72. Since the drive shaft hole 74 is compatible with the cross-sectional dimensions of the output shaft 911, the initial positioning can be completed simply by aligning the drive shaft hole 74 with the output shaft 911. After that, the crimping ring 75 is slidably sleeved on the vertical rod 72 and crimped onto the upper side of the adjusting arm fixture 73.
[0042] Test mechanism movement: Before the test begins, the controller 3 controls the electric push rod 11 to start. The output end of the electric push rod 11 pushes the slide 91. Because the dovetail block 92 at the bottom of the slide 91 is slidably installed inside the dovetail groove 8 on the test table 1, the entire test mechanism 9 can slide smoothly on the test table 1 until the output shaft 911 at the front end of the test mechanism 9 is accurately inserted into the drive shaft hole 74 of the adjusting arm clamp 73.
[0043] Torque detection: After the output shaft 911 is connected to the drive shaft hole 74, the servo motor 94 starts under the command of the controller 3. The drive shaft 95 at the output end of the servo motor 94 is connected to the test shaft 98 on the dynamic torque sensor 97 through the first coupling 99. The test shaft 98 is then connected to the output shaft 911 through the second coupling 912. This connection method places the dynamic torque sensor 97 in the entire output force transmission system. The servo motor 94 drives the drive shaft 95 to rotate, and the torque is transmitted to the test shaft 98 and the output shaft 911 in sequence through the coupling. The output shaft 911 then applies torque to the adjusting arm clamp 73. According to the principle of action and reaction, the reaction force of the torque borne by the adjusting arm clamp 73 is equal to the output torque of the output shaft 911. The dynamic torque sensor 97 can monitor this torque information in real time and obtain the dynamic data of the adjusting arm clamp 73 during the torsion process.
[0044] Data Processing and Display: The dynamic torque data acquired by the dynamic torque sensor 97 is transmitted to the controller 3 in real time. After processing the data, the controller 3 directly transmits the dynamic torque data graph to the LCD display 6 for display. By observing the data curve on the LCD display 6, the testing personnel can monitor the entire testing process in real time. After the test is completed, the testing personnel can also analyze the data curve to determine the stability of the torque transmission of the adjusting arm clamp 73. If the dynamic curve fluctuates greatly, it indicates that the internal reaction force of the adjusting arm clamp 73 is unstable, and its torque transmission is not stable enough in actual use. The test result of the adjusting arm clamp 73 is unqualified. If the curve is stable, it indicates that the torque transmission performance of the adjusting arm clamp 73 is good, and the test result is qualified.
[0045] Fixture Replacement: After the test is completed, the controller 3 controls the electric push rod 11 to start again, causing the test mechanism 9 to move away from the fixture placement mechanism 7, and the output shaft 911 is pulled out from the drive shaft hole 74 of the adjusting arm fixture 73. The operator removes the crimping ring 75, removes the tested adjusting arm fixture 73 from the vertical rod 72, and then places a new adjusting arm fixture 73 to be tested. The above test steps are repeated to achieve continuous testing of the torque of the automatic adjusting arm fixture 73.
