Abstract
Description
Technical Field
[0001] This utility model belongs to the field of watch manufacturing, and in particular relates to testing devices and watch manufacturing equipment. Background Technology
[0002] In the field of watch manufacturing and quality inspection, the assembly quality of the lugs is one of the key factors affecting the safety and user experience of wearing a watch. The lugs are protruding parts on both sides of the watch case used to connect the strap or bracelet. They typically have holes or grooves inside, with spring rods at both ends acting as connecting blocks. These springs must be precisely engaged into the lug holes to secure the strap or bracelet. The reliability of this connection directly determines whether the watch will accidentally fall off. The damping force of the lugs is a core indicator for evaluating this quality; therefore, it is necessary to test the torque of the lugs rotating relative to the watch case to obtain the damping force data.
[0003] However, the current testing of the lug torque mainly relies on manual testing, that is, the operator uses simple tools to manually rotate the lug and judges whether the damping force is "too loose", "appropriate" or "too tight" based on personal feel and experience. This testing method is highly subjective, lacks quantitative data, and the results vary from person to person, making it impossible to accurately measure the lug torque value. Utility Model Content
[0004] The purpose of this application is to provide a testing device and watch manufacturing equipment, aiming to solve the problem of how to improve the stability and accuracy of the testing device.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] In a first aspect, a testing device is provided for detecting the torque of a second component rotating relative to a first component, wherein the second component is rotatably connected to the first component. The testing device includes a fixing structure for fixing the first component, a frame spaced apart from the fixing structure, a coupling assembly rotatably connected to the frame, a clamping structure connected to one end of the coupling assembly facing the fixing structure and for clamping the second component, and a torque sensor disposed on the coupling assembly. The coupling assembly is used to rotate about a preset axis under the drive of an external force, so that the clamping structure drives the second component to rotate relative to the first component. The torque sensor detects the torque of the second component when the coupling assembly drives the clamping structure to rotate.
[0007] In some embodiments, the testing apparatus further includes a drive structure connected to the frame, the coupling assembly being connected to the rotational output end of the drive structure, and the drive structure being used to drive the coupling assembly to rotate around the preset axis.
[0008] In some embodiments, the coupling assembly includes a plurality of coupling members connected sequentially along a preset direction, the torque sensor is disposed between two adjacent coupling members, and the coupling member located at the end of the coupling assembly opposite to the clamping structure is connected to the rotational output end of the drive structure.
[0009] In some embodiments, the clamping structure includes a connecting block connected to one end of the coupling assembly facing the fixed structure and two clamping arms connected to the connecting block away from the coupling assembly. The two clamping arms are spaced apart, and a clamping space for clamping the second component is formed between the two clamping arms.
[0010] In some embodiments, the frame includes a base and a slide block slidably connected to the base, the coupling assembly is rotatably connected to the slide block, and the sliding direction of the slide block is parallel to a preset direction.
[0011] In some embodiments, the clamping arm is detachably connected to the connecting block.
[0012] In some embodiments, the fixing structure includes a placement seat for supporting the first component and a first clamping member and a second clamping member disposed on opposite sides of the placement seat along a preset direction. The first clamping member is slidably disposed along the preset direction, and the second clamping member is connected to the placement seat. The first clamping member and the second clamping member are used to jointly clamp the first component along the preset direction, and the preset direction is intersected with the preset axis.
[0013] In some embodiments, the fixing structure further includes a power member spaced apart from the placement seat along the preset direction, the first holding member being connected to the output end of the power member, and the power member being used to drive the first holding member to move along the preset direction so that the first holding member abuts against or separates from the first component.
[0014] In some embodiments, the fixing structure further includes a plurality of limiting blocks connected to the edge of the placement seat and spaced apart, the plurality of limiting blocks surrounding to form a limiting space for limiting the first component.
[0015] Secondly, a watch manufacturing apparatus is provided, which includes the testing device described above.
[0016] The beneficial effects of this application are as follows: When the testing device of this application is in use, the coupling assembly rotates around a preset axis under the drive of external force, the clamping structure clamps the second component and the clamping structure rotates with the coupling assembly, so that the clamping structure can drive the second component to rotate relative to the first component. At this time, the torque sensor detects the torque of the coupling assembly, thereby indirectly obtaining the torque data of the second component, realizing the torque detection of the second component. In particular, by measuring the torque value during the rotation of the second component by the torque sensor, the digital signal or quantized reading is output, which replaces the fuzzy evaluation relying on manual sense, which can improve the accuracy of detection. In addition, during the detection process, the fixing structure fixes the first component to ensure that the first component does not shake or shift during the detection process, thereby effectively reducing the measurement deviation caused by the instability of the first component's position, and further improving the stability and accuracy of detection.

[0027] Please see Figures 1 to 3This application provides a testing device for detecting the torque of a second component 220 rotating relative to a first component 210. The second component 220 is rotatably connected to the first component 210. The testing device includes a fixing structure 10 for fixing the first component 210, a frame 50 spaced apart from the fixing structure 10, a coupling assembly 20 rotatably connected to the frame 50, a clamping structure 30 connected to the end of the coupling assembly 20 facing the fixing structure 10 and used for clamping the second component 220, and a torque sensor 40 disposed on the coupling assembly 20. The coupling assembly 20 is used to rotate around a preset axis a under the drive of an external force, so that the clamping structure 30 drives the second component 220 to rotate relative to the first component 210. The torque sensor 40 detects the torque of the second component 220 when the coupling assembly 20 drives the clamping structure 30 to rotate.
[0028] In this embodiment, the first component 210 and the second component 220 are the watch case and lugs, respectively. The lugs are protruding parts on both sides of the watch case used to connect the watch strap or bracelet. They are usually designed with holes or grooves inside. The spring rod, as the connecting block 31, has compression springs at both ends and needs to be precisely inserted into the lug holes to fix the watch strap or bracelet. Therefore, the testing device in this embodiment can detect the torque of the lugs rotating relative to the watch case, thereby obtaining the damping force of the lugs. This damping force is a core indicator for evaluating the assembly quality of the watch. Of course, in other possible implementations, the first component 210 and the second component 220 can also be other structures that can rotate relative to each other. This embodiment does not limit the specific structure of the first component 210 and the second component 220.
[0029] Understandably, in this embodiment, the fixing structure 10, the clamping structure 30, and the coupling assembly 20 are sequentially arranged along a preset axis a, and the coupling assembly 20 extends along the preset axis a. In this embodiment, the coupling assembly 20 rotates around the preset axis a under the drive of an external force, and the clamping structure 30 rotates with the coupling assembly 20 and also rotates around the preset axis a, so that the clamping structure 30 can drive the second component 220 to rotate relative to the first component 210. That is, the coupling assembly 20, the clamping structure 30, and the second component 220 all rotate around the preset axis a. At this time, the torque sensor 40 detects the torque of the coupling assembly 20, thereby indirectly obtaining the torque data of the second component 220, thus making the torque measurement accurate.
[0030] When the testing device of this application is in use, the coupling assembly 20 rotates around a preset axis a under the drive of an external force. The clamping structure 30 clamps the second component 220 and rotates with the coupling assembly 20, so that the clamping structure 30 can drive the second component 220 to rotate relative to the first component 210. At this time, the torque sensor 40 indirectly obtains the torque data of the second component 220 by detecting the torque of the coupling assembly 20, thereby realizing the torque detection of the second component 220. In this way, the torque sensor 40 measures the torque value during the rotation of the second component 220 and outputs a digital signal or quantized reading, which replaces the fuzzy evaluation that relies on manual sense, thereby improving the accuracy of detection. In addition, during the detection process, the fixing structure 10 fixes the first component 210 to ensure that the first component 210 does not shake or shift during the detection process, thereby effectively reducing the measurement deviation caused by the unstable position of the first component 210, and further improving the stability and accuracy of detection.
[0031] Understandably, the contact surface between the clamping structure 30 and the second component 220 can be a soft contact surface, thereby enabling reliable, non-destructive, and positionally consistent clamping of the second component 220 by the clamping structure 30. This also eliminates the risk of measurement deviation and component damage caused by unstable clamping. Furthermore, embodiments of this application can perform multiple tests on the same first component 210 and second component 220 under the same conditions, thus achieving a repeatability error in torque measurement results that is far superior to the fluctuation range assessed manually.
[0032] In some embodiments, such as Figure 2 As shown, the testing device also includes a drive structure 60 connected to the frame 50. The coupling assembly 20 is connected to the rotational output end of the drive structure 60, and the drive structure 60 is used to drive the coupling assembly 20 to rotate around a preset axis. By driving the coupling assembly 20 to rotate through the drive structure 60, the clamping structure 30 and the second component 220 are driven to rotate. This accurately simulates the rotational motion mode of the second component 220, directly measures the torque required for this rotational action, eliminates errors introduced by indirect measurement methods such as axial pull-out, and ensures that the measurement results truly reflect the damping force data of the second component 220.
[0033] Furthermore, by setting up the drive structure 60, testing efficiency can be improved and testing consistency can be ensured. Operators only need to place the first component 210 and press the start button; the device automatically completes fixing, clamping, rotation, measurement, and result judgment, significantly reducing operational complexity and the skill requirements for personnel. Moreover, the testing device of this embodiment is easily integrated into automated production lines or online testing stations, meeting the requirements of high-efficiency production cycles. Optionally, the drive structure 60 can be a rotary motor, a rotary cylinder, or a precision rotary table, etc.
[0034] In some embodiments, the coupling assembly 20 and the drive structure 60 can also be connected to an electromagnetic clutch. When the electromagnetic clutch is in the closed state, the drive structure 60 is activated, and the electromagnetic clutch transmits the power of the drive structure 60 to the coupling assembly 20. When the clamping structure 30 or the coupling assembly 20 rotates under the action of an external force, the electromagnetic clutch can switch to the open state, and then the coupling assembly 20 drives the shaft to idle. In this way, the power on the coupling assembly 20 is prevented from being transmitted in reverse to the drive structure 60, thereby realizing the unidirectional output of the power of the drive structure 60 and improving the safety of the testing device.
[0035] In some embodiments, such as Figure 2 As shown, the coupling assembly 20 includes multiple connecting members 21 connected sequentially along a preset direction. The torque sensor 40 is disposed between two adjacent connecting members 21, and the connecting member 21 located at the end of the coupling assembly 20 opposite to the clamping structure 30 is connected to the rotation output end of the drive structure 60. By setting the connecting member 21, when the drive structure 60 is started, the connecting member 21 can rotate, thereby realizing the rotation of the clamping structure 30 to realize the rotation operation of the second component 220. At this time, the connecting member 21 can realize overload protection for the torque sensor 40, improving the protection of the entire testing device.
[0036] Understandably, the torque sensor 40 in this embodiment is mainly used to convert torque into a measurable electrical signal. Specifically, the torque sensor 40 can be measured using the principle of resistance strain. That is, when a metal shaft or elastic body is subjected to torque, it will undergo a small deformation, and the resistance value of the strain gauge attached to the surface will change accordingly. For example, strain gauges can be attached to the rotating shaft at a 45° angle (because the shear strain is most obvious in this direction). The strain gauges form a Wheatstone bridge to convert the resistance change into a voltage signal.
[0037] The torque sensor 40 features an extremely high sampling frequency and fast response capability, enabling it to capture minute changes in torque within a short time, thus achieving real-time monitoring of the equipment. Simultaneously, the sensor exhibits high stability, maintaining consistent performance even in harsh operating environments, ensuring the reliability of measurement data. The torque sensor 40 also possesses strong anti-interference and overload capabilities, effectively resisting the influence of external interference signals and maintaining normal operation even under overload torque, greatly improving the safety and reliability of the equipment and ensuring the accuracy of measurement data.
[0038] In some embodiments, the clamping structure 30 includes a connecting block 31 connected to one end of the coupling assembly 20 facing the fixing structure 10, and two clamping arms 32 connected to the end of the connecting block 31 facing away from the coupling assembly 20. The two clamping arms 32 are spaced apart, forming a clamping space between them for clamping the second component 220. Understandably, the rotational power of the coupling assembly 20 is first transmitted to the connecting block 31, and then through the connecting block 31 to the two clamping arms 32. The second component 220 is clamped between the two clamping arms 32. The clamping structure 30 is simple and can improve clamping efficiency.
[0039] In some embodiments, the frame 50 includes a base 51 and a slide 52 slidably connected to the base 51. The coupling assembly 20 is rotatably connected to the slide 52, and the sliding direction of the slide 52 is parallel to the preset axis a. Since the slide 52 is slidably connected to the base 51 and can slide in a direction parallel to the preset direction, the coupling assembly 20 and the clamping structure 30 can be moved toward the fixed structure 10, enabling the clamping structure 30 to clamp the second component 220. Furthermore, the clamping structure 30 can be retracted when the first component 210 is removed or placed, avoiding interference.
[0040] Optionally, an electric slide or a linear motor can be installed on the base 51, and the slide 52 can be slidably connected by mounting the slide block 52 on the electric slide or linear motor.
[0041] In some embodiments, the clamping arm 32 is detachably connected to the connecting block 31. Because the clamping arm 32 is detachably connected to the connecting block 31, it is convenient to disassemble the clamping arm 32, thereby improving maintenance convenience. Furthermore, different sizes and shapes of clamping arms 32 can be selected according to the different sizes and shapes of the first component 210 and the second component 220, thereby improving the adaptability and flexibility of the testing device. Multiple sets of clamping structures 30 are not required; only the clamping arm 32 needs to be replaced, thus saving costs. Specifically, both the clamping arm 32 and the connecting block 31 can be provided with connecting holes. Fasteners can be passed through the connecting holes on the clamping arm 32 and the connecting block 31 respectively, thereby achieving a detachable connection between the clamping arm 32 and the connecting block 31.
[0042] Optionally, the clamping arm 32 is made of aluminum alloy. In addition, a buffer layer can be provided on the contact surface between the clamping arm 32 and the second component 220. The buffer layer is made of soft or flexible materials, such as Teflon, engineering plastics or soft alloys, to avoid hard contact between the clamping arm 32 and the second component 220, thereby avoiding damage to the second component 220.
[0043] In some embodiments, such as Figure 3As shown, the fixing structure 10 includes a placement base 13 for supporting the first component 210, and a first clamping member 11 and a second clamping member 12 disposed on opposite sides of the placement base 13 along a preset direction b. The first clamping member 11 is slidably disposed along the preset direction b, and the second clamping member 12 is connected to the placement base 13. The first clamping member 11 and the second clamping member 12 are used to jointly clamp the first component 210 along the preset direction b, which intersects with a preset axis. By setting the first clamping member 11 and the second clamping member 12, the distance between the first clamping member 11 and the second clamping member 12 can be adjusted. Therefore, after the first component 210 is placed on the placement base 13, the first clamping member 11 slides toward the second clamping member 12 to clamp the first component 210. When it is necessary to remove the first component 210, the first clamping member 11 slides away from the second clamping member 12 to release the first component 210. Optionally, the preset direction b is perpendicular to the preset axis a.
[0044] In some embodiments, the fixing structure 10 further includes a power member 14 spaced apart from the placement seat 13 along a preset direction b. The first clamping member 11 is connected to the output end of the power member 14. The power member 14 is used to drive the first clamping member 11 to move along the preset direction b, so that the first clamping member 11 abuts against or separates from the first component 210. By setting the power member 14, manual intervention can be reduced, clamping efficiency can be improved, and clamping consistency can be guaranteed.
[0045] In addition, a buffer pad can be provided on the contact surface between the first holding member 11 and the first component 210. The buffer pad is made of soft or flexible material, such as Teflon, engineering plastic or soft alloy, to avoid hard contact between the first holding member 11 and the first component 210, thereby avoiding damage to the second component 220.
[0046] In some embodiments, the fixing structure 10 further includes a plurality of limiting blocks 15 connected to the edge of the placement seat 13 and spaced apart. The plurality of limiting blocks 15 surround to form a limiting space for limiting the first component 210. Therefore, the plurality of limiting blocks 15 limit the first component 210 from multiple directions, thereby improving the limiting effect on the first component 210, making the position of the first component 210 stable during the test, and thus improving the stability and accuracy of the test.
[0047] This utility model also proposes a watch production equipment, which includes a testing device. The specific structure of the testing device is as described in the above embodiments. Since this watch production equipment adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0048] In addition, since there may be multiple second components 220, for example, when the first component 210 and the second component 220 are the watch case and the lugs of the watch respectively, there are two lugs, which are located on opposite sides of the watch case. In this case, the watch production equipment may include two testing devices, which are used to test the two second components 220 connected to the same first component 210.
[0049] In summary, when the testing device of this application is in use, the coupling assembly 20 rotates around a preset axis under the drive of external force, and the clamping structure 30 clamps the second component 220 and rotates with the coupling assembly 20, so that the clamping structure 30 can drive the second component 220 to rotate relative to the first component 210. At this time, the torque sensor 40 detects the torque of the coupling assembly 20, thereby indirectly obtaining the torque data of the second component 220, realizing the torque detection of the second component 220. In particular, by measuring the torque value during the rotation of the second component 220 by the torque sensor 40 and outputting a digital signal or quantized reading, the fuzzy evaluation relying on manual sense is replaced, which can improve the accuracy of detection. In addition, during the detection process, the fixing structure 10 fixes the first component 210 to ensure that the first component 210 does not shake or shift during the detection process, thereby effectively reducing the measurement deviation caused by the unstable position of the first component 210, and further improving the stability and accuracy of detection.
