Abstract
Description
Technical Field
[0001] This utility model belongs to the field of watch quality testing technology, specifically relating to a torque testing device. Background Technology
[0002] A watch is assembled from components such as the case, strap, dial, hands, and movement. The accuracy and durability of a watch are key concerns for consumers. As a crucial part of a watch, the installation precision and torque control of the hand tubes are paramount, directly affecting the stability of the hands' rotation on the movement, their accuracy, and their lifespan. Hand tube torque refers to the torque between the hand tube and the hand face. Insufficient torque leads to a loose connection between the tube and face, making it prone to detachment under slight external force or prolonged vibration. Excessive torque can cause stress concentration in the tube or face, resulting in irreversible damage such as breakage or deformation. Both insufficient and excessive torque ultimately disrupt the smooth rotation of the hands on the movement's axis, causing inaccurate timekeeping and significantly shortening the watch's lifespan. Currently, the industry primarily relies on traditional manual force testing or simple fixed testing fixtures for tensile testing to assess the torque connection strength of the hand tubes. However, manual force testing relies on the tester's experience and feel, resulting in a slow testing process that is difficult to meet the requirements of rapid testing on mass production lines. Furthermore, it is difficult to precisely control the magnitude and direction of the applied torque, leading to large fluctuations and poor repeatability in test results. While fixed tensile testing fixtures can solve these problems, they still have issues with guaranteeing measurement accuracy. Uneven force application, overload, or improper clamping can easily cause bending, scratches, or even breakage of the pointer or insert, resulting in additional quality losses and costs. Moreover, they are difficult to adapt to different models and functions of pointer inserts, leading to poor versatility. Utility Model Content

[0029] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.
[0030] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.
[0031] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.
[0032] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.
[0033] It should be noted that, as Figure 1 and Figure 5 As shown, the torque testing device 100 is used to detect the torque value of the object under test, and is suitable for detecting the torque value of two connecting parts connected at a certain angle. Specifically, in this embodiment, the torque testing device 100 is mainly used to detect the torque value of the watch hand insert 200, specifically the torque value of the watch hand 201, such as the hour hand, minute hand, or second hand, relative to the insert 202. Of course, in other embodiments, the torque testing device 100 can also be used to detect the torque value of other objects under test, and no particular limitation is made here.
[0034] This utility model embodiment provides a torque testing device 100, such as Figures 1 to 6 As shown, the torque testing device 100 includes a rotating component 1, a torque actuating component 2, an adjusting clamp 3, a torque meter 4, and a fixed base 5.
[0035] Both the rotating component 1 and the torque meter 4 are rotatably mounted on the fixed base 5, and the torque actuating component 2 is mounted on the rotating component 1. Understandably, the torque actuating component 2 acts on the hands 201, such as the hour, minute, or second hands, and applies torque to the hands 201 to create torsional stress relative to the insert tube 202. Specifically, by applying an external force to the rotating component 1, the rotation of the rotating component 1 causes the torque actuating component 2 to rotate, thereby creating torque on the hands 201. The adjusting clamp 3 includes an adjusting member 31 and a clamping member 32. The clamping member 32 has a clamping groove, and the side of the clamping member 32 with the clamping groove is opposite to the torque actuating member 2. The clamping groove of the clamping member 32 is used to clamp the insert 202. By having the side of the clamping member 32 with the clamping groove opposite to the torque actuating member 2, when the clamping groove of the clamping member 32 clamps the insert 202, the torque actuating member 2 can act on the pointer 201, thereby applying torque to the pointer 201, so that the pointer 201 forms torsional stress relative to the insert 202. The clamping member 32 is connected to the torque meter 4 through the adjusting member 31, and the adjusting member 31 is movably disposed on the torque meter 4. The adjusting member 31 has a first position and a second position. When the adjusting member 31 is in the first position, the clamping groove of the clamping member 32 is in an open state. When the adjusting member 31 is in the second position, the clamping groove of the clamping member 32 is in a tightened state. Understandably, the torque meter 4 is connected to the clamping member 32 via the adjusting member 31. Therefore, when the torque actuating member 2 acts on the hand 201, the clamping groove of the clamping member 32 clamps the insert 202, and an external force is applied to the rotating member 1, the rotating member 1 rotates, causing the torque actuating member 2 to rotate, thereby generating torque on the hand 201. As the clamping member 32 rotates, the torque meter 4 rotates relative to the fixed seat 5. Therefore, the applied torque can be obtained in real time based on the rotation amplitude of the torque meter 4. Specifically, by controlling the position of the adjusting member 31, when the adjusting member 31 moves relative to the torque meter 4 towards the first position, the clamping groove of the clamping member 32 gradually opens; when the adjusting member 31 moves relative to the torque meter 4 towards the second position, the clamping groove of the clamping member 32 gradually tightens. Therefore, the size of the clamping groove of the clamping member 32 can be adjusted according to the model and specifications of the hand insert 200 to be tested, to adapt to different watch hand insert 200 models and improve versatility.
[0036] In this embodiment, the torque testing device 100 detects the following: the insert 202 of the needle insert 200 to be tested is placed on the clamping groove of the clamping member 32. According to the relative size of the insert 202 and the clamping groove, the adjusting member 31 is adjusted to move relative to the torque meter 4 towards the first position or the second position, so that the clamping groove of the clamping member 32 is adjusted to suit the size of the insert 202 and the insert 202 is clamped. Then, the torque actuating member 2 acts on the needle 201 of the needle insert 200 to be tested and applies torque to the rotating member 1, driving the torque meter 4 to rotate, thereby measuring the magnitude of the applied torque.
[0037] In summary, the torque testing device 100 applies torque to the pointer 201 via a torque actuating element 2, clamps the insert 202 via a clamping groove in clamping element 32, and applies external force to rotating element 1. The rotation of rotating element 1 causes torque actuating element 2 to rotate, thus generating torque on the pointer 201. This, in turn, causes torque meter 4 to rotate. The magnitude of the applied torque is obtained in real time through the rotation amplitude of torque meter 4. Therefore, the magnitude and direction of the applied torque can be precisely controlled by the real-time torque, resulting in high measurement accuracy and effectively avoiding large fluctuations in test results, poor repeatability, and issues with the pointer 201 or insert. This invention addresses issues such as damage to the 202 insert tube. It features a simple structure, convenient operation, and strong practicality. By controlling the position of the adjusting component 31, the adjusting component 31 can be adjusted relative to the torque meter 4 to move towards the first or second position according to the relative size of the insert tube 202 and the clamping groove. This allows the clamping groove of the clamping component 32 to be adjusted to fit the size of the insert tube 202 and clamp the insert tube 202. Therefore, the size of the clamping groove of the clamping component 32 can be adjusted according to the model and specifications of the watch hand insert tube 200 to be tested, so as to adapt to different watch hand insert tube models and improve versatility.
[0038] In some embodiments, such as Figure 2 and Figure 3As shown, the adjusting member 31 includes a connecting sleeve 311 and an adjusting sleeve 312 connected to the connecting sleeve 311; the torque meter 4 is provided with a connecting part 41, the connecting sleeve 311 is sleeved on the connecting part 41 and threadedly connected to the connecting part 41; the radial area of the adjusting sleeve 312 gradually decreases from one end near the connecting sleeve 311 to the other end, that is, the adjusting sleeve 312 has a conical sleeve structure; the clamping member 32 includes at least three elastically connected clamping blocks 321, each clamping block 321 cooperates to form a clamping groove, the clamping blocks 321 are supported on the connecting part 41, and the adjusting sleeve 312 is sleeved on the outside of the clamping blocks 321. The threaded connection between the connecting sleeve 311 and the connecting part 41 of the torque meter 4 allows for precise control of the insertion depth of the adjusting sleeve 312, thereby precisely controlling its axial displacement. This axial displacement of the adjusting sleeve 312 translates into precise control of the radial displacement of the clamping block 321, achieving stable clamping of the insert 202 and accommodating inserts 202 of different specifications. Therefore, when inserts 202 of different diameters are inserted into the clamping groove formed by the clamping block 321, rotating the adjusting sleeve 312 causes its conical inner wall to radially compress the clamping block 321. Because the clamping blocks 321 are elastic, they can contract synchronously and evenly toward the center, thus tightly and securely wrapping the outer wall of the inserts 202 of different diameters. Therefore, it is not necessary to replace the clamping parts 32 of different sizes to adapt to inserts 202 of different diameters, improving versatility. Moreover, the threaded connection adjustment method has the characteristics of a stable connection, which can provide sufficient and adjustable clamping force to ensure that the inserts 202 do not slip or rotate during the test, so as to ensure that the torque test results accurately reflect the bonding force between the inserts 202 and the pointer 201 rather than clamping failure.
[0039] In some embodiments, such as Figure 2 , Figure 3 and Figure 6As shown, each clamping block 321 has a connecting hole 322 on both sides along its circumferential direction. The clamping member 32 also includes a first elastic member 323. The two connecting holes 322 between two adjacent clamping blocks 321 are connected by a first elastic member 323. That is, the clamping blocks 321 are connected in the torsional direction by a first elastic member 323. The first elastic members 323 are connected end to end in sequence so that all clamping blocks 321 cooperate to form a closed ring elastic structure. The clamping blocks 321 are connected by a first elastic element 323, allowing multiple clamping blocks 321 to contract or release radially in a coordinated and uniform manner to accommodate inserts 202 of different sizes. During torque testing, when torque is applied to the clamping blocks 321 and the inserts 202, the inserts 202 generate a reaction force attempting to loosen the clamping blocks 321. The connection of the first elastic element 323 between adjacent clamping blocks 321 effectively enhances the structural rigidity and integrity of the entire clamping component 32 in the torsional direction, effectively preventing relative sliding, misalignment, or loosening of the clamping blocks 321 under torque, ensuring the accuracy of torque transmission and the stability of the testing process. Specifically, the first elastic element 323 can be a spring, and the spring and the connecting hole 322 can be connected by welding, snap-fit connection, pin connection, etc., without particular limitation. Specifically, in this embodiment, three clamping blocks 321 are provided, and each clamping block 321 has a connecting hole 322 on both sides of its circumferential direction; the clamping member 32 also includes three first elastic members 323, and the two connecting holes 322 between two adjacent clamping blocks 321 are connected by a first elastic member 323, and the three first elastic members 323 are connected end to end in sequence.
[0040] In some embodiments, such as Figure 3 As shown, three clamping blocks 321 cooperate to form a clamping member 32 with a radial area that gradually decreases from one end near the connecting sleeve 311 to the other. This results in the outer wall of the clamping member 32 forming a tapered structure that fits the adjusting sleeve 312. While precisely controlling the radial contraction or release of the clamping blocks 321 when the adjusting sleeve 312 moves axially, it also increases the contact area between the cavity wall of the adjusting sleeve 312 and the outer wall of the clamping blocks 321, thereby further effectively preventing the clamping blocks 321 from sliding, misaligning, or loosening under torque. It should be noted that in other embodiments, the number of clamping blocks 321 is not limited to three; other numbers such as two, four, or five are also applicable and can be specifically set according to actual needs. No particular limitation is made here.
[0041] In some embodiments, such as Figure 1 and Figure 2As shown, the torque meter 4 includes a torque base 42 and a scale base 43; the adjusting member 31 is movably disposed on the torque base 42; the outer peripheral wall of the torque base 42 is provided with a first scale 421, and the outer peripheral wall of the scale base 43 is provided with a second scale 431; the scale base 43 is disposed on the fixed base 5, and the torque base 42 is rotatably disposed on the scale base 43 and coaxially disposed with the scale base 43. Understandably, since the torque seat 42 rotates with the clamping member 32 and the scale seat 43 is fixed on the fixed seat 5 to be fixed relative to the torque seat 42, when the torque actuating member 2 acts on the pointer 201, the clamping groove of the clamping member 32 clamps the insert 202, and an external force is applied to the rotating member 1, the rotating member 1 rotates and drives the torque actuating member 2 to rotate to form torque on the pointer 201, thereby driving the clamping member 32 to rotate, which in turn drives the torque seat 42 to rotate relative to the scale seat 43. Therefore, according to the rotation amplitude of the torque seat 42, that is, according to the value of the first scale 421 rotating relative to the second scale 431, the applied torque value can be obtained in real time and accurately. Thus, the torque value can be converted into an intuitive physical scale position, reducing errors and providing accurate and stable torque output to accurately measure the torque bearing capacity of the pointer insert 200.
[0042] In some embodiments, such as Figure 2 As shown, a groove 432 is recessed at the center of the scale seat 43, and a bearing 433 is disposed within the groove 432. A fixed shaft 434 is connected to the inner ring of the bearing 433, and a first step 435 is provided at the end of the fixed shaft 434 away from the bearing 433. A fixing hole 422 is formed at the center of the torque seat 42 along its axial direction, and a second step is provided on the wall of the fixing hole 422. The torque seat 42 is coaxially mounted with the scale seat 43 through the insertion and engagement of the fixing hole 422 and the fixed shaft 434, with the second step resting on the first step 435. Understandably, by setting this mating structure of the bearing 433 and the fixed shaft 434, the coaxiality of the torque seat 42 and the scale seat 43 can be ensured, improving the accuracy of torque value detection. Furthermore, it provides support for the torque seat 42, effectively preventing wear caused by contact friction during rotation relative to the scale seat 43. The bearing 433 also improves the smoothness of rotation. It should be noted that both the scale seat 43 and the torque seat 42 are annular sleeve structures, and the bottom end face of the torque seat 42 rests on the top end face of the scale seat 43, with their scale surfaces flush. The bottom of the scale seat 43 is sealed to facilitate the placement of the bearing 433. The connecting part 41 is provided on the torque seat 42. The two can be integrally formed or separately connected. The radial length of the torque seat 42 is greater than the radial length of the connecting part 41, so that the upper end face of the torque seat 42 can restrict the connecting sleeve 311, effectively preventing the connecting sleeve 311 from unscrewing out of the connecting part 41.
[0043] In some embodiments, such as Figure 2As shown, the fixed base 5 is provided with a stepped groove 51, and the scale seat 43 is engaged in the stepped groove 51 and detachably pressed onto the fixed base 5 by multiple clamping members 52. Specifically, the stepped groove 51 may be provided with an elastic layer, specifically an elastic adhesive layer, which can fill the gap between the scale seat 43 and the stepped groove 51 of the fixed base 5 to improve the contact stability between the two. In addition, the multiple clamping members 52 press the scale seat 43 onto the fixed base 5 in the circumferential direction, which can make the fixed base 5 and the scale seat 43 firmly connected, effectively preventing the scale seat 43 from rotating under the action of torque, thus affecting the accuracy of torque measurement.
[0044] Specifically in this embodiment, such as Figure 2 As shown, the peripheral wall of the scale seat 43 near the fixed seat 5 is provided with a groove 436; the clamping member 52 includes a first clamping block 521 and a second clamping block 522 connected to the first clamping block 521. The first clamping block 521 is connected to the fixed seat 5 via a locking member, and the second clamping block 522 extends radially into the scale seat 43 and is clamped in the groove 436. Specifically, the first clamping block 521 and the second clamping block 522 are vertically connected to form a T-shaped clamping member 52. The first clamping block 521 of the T-shaped clamping member 52 is locked to the fixed seat 5, and the second clamping block 522 is clamped in the groove 436 of the scale seat 43, which can firmly fix the scale seat 43 to the fixed seat 5 and has the feature of easy disassembly. Of course, in other embodiments, the fixed seat 5 and the scale seat 43 can also be connected by welding, pinning, etc., and no particular limitation is made here. In this embodiment, two clamping members 52 are provided, symmetrically arranged on opposite sides of the scale base 43, which can provide a stable locking force and facilitate quick disassembly or fine-tuning of position. Of course, in other embodiments, the clamping members 52 can also be adapted to other numbers and shapes, without particular limitation.
[0045] In some embodiments, such as Figure 2As shown, the rotating component 1 includes an adjusting screw 11, an adjusting nut 12, and a rotating handle 13; the adjusting screw 11 is movably mounted on the fixed seat 5, and the adjusting screw 11 is locked by the adjusting nut 12; the adjusting screw 11 has a movable cavity 111 inside, the rotating handle 13 extends movably into the movable cavity 111 and is connected to the torque-acting component 2; and a second elastic component is provided between the rotating handle 13 and the cavity wall of the movable cavity 111. Specifically, the torque actuator 2 acts on the pointer 201 of the pointer insert 200 to be tested. Therefore, when a torque test is required, the torque actuator 2 needs to be moved towards the clamping member 32 so that the torque actuator 2 can contact the pointer 201. By adjusting the threaded engagement of the adjusting nut 12 and the adjusting screw 11, the torque actuator 2 can be adjusted to a suitable height, that is, the working part of the torque actuator 2 is adjusted to have a slight height difference with the pointer 201. With the rotation handle 13 and the internal movable cavity 111 of the adjusting screw 11 being elastically connected through the second elastic member, the height of the torque actuator 2 can be further precisely adjusted, so that the torque actuator 2 abuts against the side of the pointer 201 to push the pointer 201 to rotate and generate torque. Therefore, the rotating member 1 can form coarse and fine adjustment of the height of the torque actuator 2, so that the torque actuator 2 can accurately act on the pointer 201 to generate torque. The specific adjustment operation is as follows: First, adjust the torque-acting component 2 to a slight height difference with the pointer 201 by adjusting the threaded engagement of the adjusting nut 12 and the adjusting screw 11. Then, rotate the handle 13 to press down and rotate at the same time, so that the torque-acting component 2 abuts against the side of the pointer 201 and pushes the pointer 201 to rotate to form torque.
[0046] In some embodiments, such as Figure 4 As shown, the torque-acting component 2 is provided with two actuating posts 21, which are spaced apart. Understandably, by providing these two actuating posts 21, regardless of whether the handle 13 is rotated clockwise or counterclockwise, the actuating posts 21 can abut against the side of the hands 201 and push the hands 201 to rotate, generating torque. Specifically, the actuating post 21 is a cylinder, and its smooth outer surface effectively prevents damage to the hands 201. Furthermore, the diameter of the actuating post 21 is 1mm to 3mm, and its height is 2mm to 5mm.
[0047] In some embodiments, such as Figure 1As shown, the fixed base 5 includes a base 53, a column 54, and a support column 55. The support column 55 is connected to the base 53 via the column 54 and suspended on the base 53. The torque meter 4 is mounted on the base 53, and the rotating component 1 is mounted on the support column 55. Thus, through the cooperation of the base 53, column 54, and support column 55, the rotating component 1, the torque actuator 2, the torque meter 4, and the adjusting clamp 3 are adapted to specific positions, and the rotating component 1 and the torque actuator 2 are suspended above the adjusting clamp 3, facilitating torque testing. Specifically, the base 53 has a ring-shaped structure, and the radial length of the base 53 is greater than the radial length of the scale seat 43 and the torque seat 42, so that the base 53 forms a stable foundation support, thereby securely installing each component in its corresponding position.
[0048] The above embodiments are not an exhaustive list based on the present invention, and there may be other embodiments not listed. Any substitutions and improvements made without departing from the concept of the present invention are within the protection scope of the present invention.
