[0032] When testing the thread transmission efficiency (i.e., the relationship between input torque and output force after thread engagement) of a non-standard bolt assembly, the part to be clamped is the bolt assembly, including a screwed bolt and a nut, and the outer edge surface of the nut has at least one first clamping portion. When testing the thread transmission efficiency (i.e., the relationship between input torque and output force after thread engagement), it is necessary to clamp bolt assemblies of different sizes, and secondly, during the test, it is necessary to prevent the nut from rotating with the bolt so that the nut slides along the length direction with the rotation of the bolt.

[0033] Based on the above problems, an embodiment of the present disclosure provides a clamping assembly that can clamp bolt assemblies of different sizes, while also being able to avoid the occurrence of inaccurate detection results caused by the nut rotating with the bolt.

[0034] Figure 1 The figure shows the overall structure of the clamping assembly in the embodiment of the present disclosure. Figure 1 In the example, the clamping assembly includes: a first fixing member 10 , a second fixing member 20 and a third fixing member 30 .

[0035] The first fixing member 10 and the second fixing member 20 are spaced apart in the length direction of the bolt 100, and the bolt 100 is rotatably arranged on the first fixing member 10 around its length direction. Exemplarily, the first fixing member 10 has a first abutting portion 11 abutting against the head of the bolt 100. The first abutting portion 11 is detachably arranged on the first fixing member 10 to adapt to the bolts 100 of different sizes.

[0036] The third fixing member 30 is slidably arranged along the length direction of the bolt 100, and is combined with the second fixing member 20 with a limited rotation range. The wall surface of the third fixing member 30 facing the first fixing member 10 is provided with at least one second clamping portion 31 for matching with at least one first clamping portion 201, so as to limit the rotation of the nut 200 when the clamping is formed, so that the nut 200 slides along the length direction with the rotation of the bolt 100. Exemplarily, the first clamping portion 201 is implemented as a clamping groove, and the second clamping portion 31 is implemented as a clamping block inserted into the clamping groove. Through the above arrangement, it is possible to clamp bolt 100 assemblies of different sizes for subsequent detection, and at the same time, the second clamping portion 31 arranged on the third fixing member 30 can abut against the nut 200 to prevent the rotation of the nut 200 from being restricted, so that the nut 200 slides along the length direction with the rotation of the bolt 100.

[0037] exist Figure 1 In the example, the first fixing member 10 and the second fixing member 20 are connected by at least one adjusting unit 40. The adjusting unit 40 includes a plurality of adjusting portions 41 and a fixing portion 42 engaged with the adjusting portions 41. The plurality of adjusting portions 41 are formed on the second fixing member 20 at intervals along the length direction, and the fixing portion 42 is slidably connected to the first fixing member 10 along a direction perpendicular to the length direction to be engaged with the adjusting portion 41.

[0038] The second fixing member 20 includes a second fixing seat 21 and at least one guide column 22. The guide column 22 extends from the second fixing seat 21 toward the wall of the first fixing member 10 along the length direction. The multiple adjustment parts 41 are formed on the guide column 22 at intervals along the length direction. The first fixing member 10 includes a first fixing seat 12 and at least one guide cylinder 13. Exemplarily, the guide cylinder 13 has a guide cavity (not shown in the figure), and the guide column 22 is adapted to be slidably combined in the guide cavity of the guide cylinder 13 along the length direction. Exemplarily, the guide column 22 is implemented as four, and correspondingly, the guide cylinder 13 is also implemented as four. The four guide columns 22 are distributed in a rectangular shape on the wall of the second fixing seat 21 toward the first fixing member 10, and extend from the second fixing seat 21 toward the wall of the first fixing member 10 along the length direction.

[0039] At this time, each guide column 22 is formed with a plurality of adjustment portions 41 spaced apart along the length direction, and the fixing portion 42 is implemented as two, each fixing portion 42 penetrates the two guide cylinders 13 arranged up and down, and is respectively engaged with the adjustment portion 41 of the guide column 22 in the two guide cylinders 13 arranged up and down, so as to save the steps of operating the fixing portion 42 and improve the efficiency. In another embodiment, the upper ends of the two fixing portions 42 can be connected by a connecting rod, which can further reduce the steps of operating the fixing portion 42.

[0040] When the guide post 22 and the guide cylinder 13 are implemented as four, the adjusting unit 40 is implemented as one, two or four. When the adjusting unit 40 is implemented as one, it is formed on the guide post 22 and the guide cylinder 13 of one sliding fit, and the guide posts 22 and the guide cylinder 13 of the other three sliding fits only play a supporting role. When the adjusting unit 40 is implemented as two or three, refer to the above embodiment. In another embodiment, the guide post 22 and the guide cylinder 13 can also be implemented as a pair, and at this time, the adjusting unit 40 is implemented as one or a pair.

[0041] Exemplarily, the adjusting portion 41 is implemented as an adjusting hole, and the fixing portion 42 is implemented as a fixing pin adapted to the adjusting hole. For example, the adjusting hole is implemented as a circular hole or a rectangular hole, and the fixing pin is implemented as a circular or rectangular shape adapted thereto. When the adjusting portion 41 is implemented as a circular hole, the fixing pin can be threadedly connected to the first fixing member 10 in a direction perpendicular to the length direction to engage with the adjusting portion 41. In another embodiment, the adjusting portion 41 can also be implemented as a ratchet bar, and the fixing portion 42 is implemented as a ratchet pawl between two adjacent ratchets on the ratchet bar.

[0042] In another embodiment, the guide post 22 and the guide cavity are implemented in a circular shape. When the guide post 22 and the guide cavity are implemented in a circular shape, the guide post 22 and the guide cylinder 13 can also be implemented as a pair, and the pair of guide posts 22 or the guide cylinder 13 are symmetrically distributed along the length direction to prevent the first fixing member 10 and the second fixing member 20 from rotating, thereby preventing the first fixing member 10 and the second fixing member 20 from being unable to effectively clamp the bolt 100 assembly. In another embodiment, the guide post 22 and the guide cavity are implemented in a rectangular shape. When the guide post 22 and the guide hole are implemented in a rectangular shape, the guide post 22 and the guide cylinder 13 can be implemented as one.

[0043] In another embodiment, the first fixing member 10 may also only include a first fixing seat 12, the first fixing seat 12 forms a matching number of guide holes for the four guide columns 22 to slide along the length direction, and the fixing portion 42 is slidably connected to the first fixing member 10 along a direction perpendicular to the length direction to engage with the adjustment portion 41.

[0044] In another embodiment, the plurality of adjusting portions 41 may also be formed on the first fixing member 10 , and the fixing portion 42 is slidably connected to the second fixing member 20 .

[0045] Figure 2 The figure shows a schematic cross-sectional view of an embodiment of the present disclosure. Figure 1 and Figure 2 In the example, the wall surface of the second fixing member 20 facing away from the first fixing member 10 is provided with a connecting column 23 extending along the length direction, and the third fixing member 30 is slidably connected to the connecting column 23. For example, the connecting column 23 is implemented as a cylinder, and a circular hole (not shown in the figure) is formed on the third fixing member 30 for slidingly engaging with the rectangular connecting column 23. In another embodiment, the connecting column 23 is implemented as a rectangular column, and a rectangular hole is formed on the second fixing member 20 for sliding the rectangular connecting column 23. In this way, the rotation range of the second fixing member 20 can be limited, and the third fixing member 30 can be slidably connected to the connecting column 23.

[0046] The third fixing member 30 includes a pressure plate 32 and a connecting member 33. The pressure plate 32 is relatively slidably arranged on the connecting column 23 along the length direction. The connecting member 33 includes at least one force column 331 and a connecting plate 332, the force column 331 extends along the length direction and connects the pressure plate 32 and the connecting plate 332, and the second clamping portion 31 is detachably arranged on the wall surface of the connecting plate 332 facing the first fixing member 10. Exemplarily, the force column 331 is implemented as a pair, and the pair of force columns 331 are symmetrically distributed along the length direction and connect the pressure plate 32 and the connecting plate 332, so as to improve the uniformity of the pressure applied by the connecting plate 332 to the pressure plate 32.

[0047] Figure 3 FIG. 1 is a schematic diagram showing another perspective of the overall cross-section of the embodiment of the present disclosure. Figure 1 , Figure 2 and Figure 3 For example, a clamping seat 34 is further provided between the second clamping portion 31 and the connecting plate 332, and the clamping seat 34 is detachably connected to the wall surface of the connecting plate 332 facing the first fixing member 10. For example, it is threadedly connected. In this way, by replacing the second clamping portion 31 on a different clamping seat 34, the replaced second clamping portion 31 can be clamped to the first clamping portion 201 on the nut 200 with different outer diameters.

[0048] In some embodiments, the second clamping portion 31 is arranged on the clamping seat 34 in an adjustable position. For example, the clamping seat 34 is provided with a plurality of slots at intervals along the radial direction on the wall surface facing the first fixing member 10, and one end of the second clamping portion 31 can be plugged in and out of the slot, for example, the second clamping portion 31 is interference fit with the slot to prevent the second clamping portion 31 from falling out of the slot. In this way, by inserting the second clamping portion 31 into the slot at different positions, the distance between the second clamping portion 31 and the center of the circle can be adjusted to clamp the nut 200 of different outer diameters without disassembling the clamping seat 34, which is easy to operate and improves the replacement efficiency. Alternatively, the clamping seat 34 is provided with a slide groove along the radial direction on the wall surface facing the first fixing member 10, and the second clamping portion 31 is slidably combined with the slide groove. For example, the second clamping portion 31 matches the size of the slide groove, so that the second clamping portion 31 on the wall surface cannot effectively clamp the nut 200 due to loosening in the slide groove.

[0049] In another embodiment, the second clamping portion is implemented as a pair, and the distance between the pair of second clamping portions is adjustable and arranged on the third fixing member 30. The manner in which the distance between the pair of second clamping portions is adjustable can be implemented in the above manner.

[0050] exist Figure 2 In the example, a first avoidance hole 3401 for inserting the bolt 100 is formed inside the clamping seat 34 along the length direction.

[0051] Back to Figure 1 In the example, another embodiment of the present disclosure discloses a detection device, including a main body, the clamping assembly, a driving member 60 and a detection member 70 .

[0052] The driving member 60 is arranged on the main body to drive the bolt 100 to rotate. The detection member 70 is arranged on the main body in an adjustable position relative to the driving member 60 along the length direction; the detection member 70 is located in the direction of the third fixing member 30 facing away from the first fixing member 10, and a pressure sensor 71 is arranged on the wall of the detection member 70 facing the third fixing member 30, and the pressure sensor 71 obtains the pressure detection result after abutting against the third fixing member 30. Exemplarily, the detection member 70 is arranged between the main tightening member 51 and the pressure plate 32.

[0053] Back to Figure 1 In the example, the connecting column 23 can also be slidably connected to the detection member 70, and the clamping assembly further includes a main tightening member 51 and a secondary tightening member 52. Exemplarily, the detection member 70 has an escape cavity. The main tightening member 51 is sleeved on one end of the connecting column 23 that passes through the escape cavity, and the secondary tightening member 52 is screwed on one end of the connecting column 23 that passes through the escape cavity to press against the main tightening member 51.

[0054] The first fixing seat 12 is formed with a second avoidance hole 1201 along the length direction for connecting the driving member with the bolt 100 .

[0055] In summary, the present disclosure provides a clamping assembly and a detection device in an embodiment for clamping bolt assemblies of different sizes, including a screwed bolt and a nut, and the outer edge surface of the nut has at least one first clamping portion. It includes a first fixing member and a second fixing member with adjustable spacing in the length direction of the bolt, and the bolt can be rotatably arranged on the first fixing member around its length direction; a third fixing member is slidably arranged along the length direction of the bolt and is combined with the second fixing member with a limited rotation range, and the wall surface of the third fixing member facing the first fixing member is provided with at least one second clamping portion for matching with at least one first clamping portion to limit the rotation of the nut when the clamping is formed, so that the nut slides along the length direction with the rotation of the bolt. The detection device includes a main body, a clamping assembly, a driving member and a detection member, wherein the driving member is arranged on the main body to drive the bolt to rotate; the detection member is arranged on the main body in an adjustable position relative to the driving member along the length direction; the detection member is located in the direction of the third fixing member facing away from the first fixing member, and a pressure sensor is arranged on the wall of the detection member facing the third fixing member, and the pressure sensor obtains the pressure detection result after abutting against the third fixing member. Through the above arrangement, it is possible to clamp bolt assemblies of different sizes for subsequent detection, and at the same time, the second clamping portion arranged on the third fixing member can abut against the nut to prevent the rotation of the nut from being restricted, so that the nut slides along the length direction with the rotation of the bolt. At the same time, it is avoided that the detection result is inaccurate due to the rotation of the nut.

[0056] The above embodiments are merely illustrative of the principles and effects of the present disclosure, and are not intended to limit the present disclosure. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present disclosure. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in the present disclosure shall still be covered by the protection scope of the present disclosure.
