The traditional tightening torque generally adopts the test method and the experience method. The test method determines the tightening torque of the threaded connection according to the test results and considers a certain safety margin. The experience method calibrates the tightening torque according to the tightening experience of the operator. These two methods superficially determine the tightening torque, seemingly meet the requirement of fixed torque, and improve the consistency of threaded connection assembly, but ignore the characteristics of threaded connection, that is, the tightening torque and the pre-tightening force are not a one-to-one correspondence. The pre-tightening force deviation is large with the same tightening torque, because the torque tightened by the operator cannot be guaranteed to be consistent every time, so high-precision equipment is needed to control the installation quality of each pipeline and pipe joint.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] like Figures 1 to 5 As shown, the detection device for detecting the installation quality of pipe fittings in this embodiment includes a first clamping and positioning mechanism 1, a second clamping and positioning mechanism 2, and a detection mechanism 3. The first clamping and positioning mechanism 1 is used to clamp the first pipe fitting 91, and the second clamping and positioning mechanism 2 is used to clamp the second pipe fitting 92.

[0034] The detection mechanism 3 includes a transmitting optical fiber 31 and a receiving optical fiber 32, which are located above and below the connection between the first pipe fitting 91 and the second pipe fitting 92, respectively. The transmitting optical fiber 31 is used to transmit a light beam to the receiving optical fiber 32. The detection mechanism 3 is used to determine whether the first pipe fitting 91 and the second pipe fitting 92 are installed in place based on whether the receiving optical fiber 32 receives the light beam.

[0035] The detection device for detecting the installation quality of the pipe fittings in the embodiment is used in work. The external conveying equipment conveys the connected first pipe fitting 91 and the second pipe fitting 92 to the detection device. The first clamping positioning mechanism 1 and the second clamping positioning mechanism 2 clamp the first pipe fitting 91 and the second pipe fitting 92 respectively. The emitting optical fiber 31 emits the light beam to the receiving optical fiber 32. When the first pipe fitting 91 and the second pipe fitting 92 are installed in place, there is no gap between the first pipe fitting 91 and the second pipe fitting 92. The light beam emitted by the emitting optical fiber 31 is blocked by the first pipe fitting 91 and the second pipe fitting 92. The receiving optical fiber 32 cannot receive the light beam emitted by the emitting optical fiber 31. It is judged that the first pipe fitting 91 and the second pipe fitting 92 are installed in place. When the first pipe fitting 91 and the second pipe fitting 92 are not installed in place, a gap is formed between the first pipe fitting 91 and the second pipe fitting 92. The light beam emitted by the emitting optical fiber 31 passes through the gap and reaches the receiving optical fiber 32. The receiving optical fiber 32 can smoothly receive the light beam emitted by the emitting optical fiber 31. It is judged that the first pipe fitting 91 and the second pipe fitting 92 are not installed in place. The detection device for detecting the installation quality of the pipe fittings in the embodiment detects the installation quality of the pipe fittings by using the opposite emitting optical fiber. Compared with the visual detection method, the anti-interference ability is strong, the environmental dependence is low, the adaptability is strong, and the cost is low.

[0036] Further, as shown in Figure 1 and Figure 2 In the embodiment, the first clamping positioning mechanism 1 includes the first clamping jaw 11 for clamping the first pipe fitting 91. The second clamping positioning mechanism 2 includes the second clamping jaw 21 for clamping the second pipe fitting 92. The first clamping jaw 11 is located on one side of the second clamping jaw 21. The bayonet of the first clamping jaw 11 and the second clamping jaw 21 is perpendicular to the vertical direction. The bayonet of the first clamping jaw 11 and the second clamping jaw 21 is arranged vertically. The first pipe fitting 91 and the second pipe fitting 92 can be constrained in multiple degrees of freedom. The structure is simple and the positioning is reliable.

[0037] Further, as shown in Figures 1 to 4 In the embodiment, the bottom of the first clamping jaw 11 is connected with the longitudinal movement assembly 12. The longitudinal movement assembly 12 drives the first clamping jaw 11 to move longitudinally. The longitudinal direction is the connection direction of the first pipe fitting 91 and the second pipe fitting 92. After the detection mechanism 3 completes the detection, the longitudinal movement assembly 12 drives the first clamping jaw 11 to move in the direction away from the connection direction of the first pipe fitting 91 and the second pipe fitting 92 (upward in Figure 3 The longitudinal movement assembly 12 verifies whether the first pipe fitting 91 and the second pipe fitting 92 are installed in place. The detection mechanism 3 can prevent the missed detection of the pipe fittings not installed in place. The reliability is better.

The longitudinal movement driving member 121 drives the mounting plate 122 to move longitudinally, and drives the first clamping jaw 11 on the mounting plate 122 to move, which is simple and reliable in structure. The longitudinal movement driving member 121 is a linear motor, an oil cylinder or a gas cylinder, etc.

[0039] Preferably, in the embodiment, a plurality of first clamping jaws 11 and a plurality of second clamping jaws 21 are arranged, the plurality of first clamping jaws 11 can move synchronously with the mounting plate 122, and can simultaneously detect a plurality of groups of first pipes 91 and second pipes 92, which is high in detection efficiency.

[0040] Further, as shown in Figures 1 to 3 and Figure 5 As shown, in the embodiment, the bottom of the mounting plate 122 is connected with a transverse movement assembly 14, and the transverse movement assembly 14 is used to drive the mounting plate 122 to move transversely. The transverse movement assembly 14 is used to drive the mounting plate 122 to move transversely (left and right directions) in the longitudinal direction of the mounting plate 122, which can adjust the transverse position of the first clamping jaw 11 to align with the first pipe 91, and is high in adaptability. The transverse movement assembly 14 is a linear motor module. Figure 3

[0041] Further, as shown in Figures 1 to 4 As shown, in the embodiment, the upper and lower parts of the first clamping jaw 11 are respectively connected with optical fiber seats 33, and the emitting optical fiber 31 and the receiving optical fiber 32 are arranged on the two optical fiber seats 33. The emitting optical fiber 31 and the receiving optical fiber 32 are connected with the first clamping jaw 11 through the optical fiber seats 33, so that the emitting optical fiber 31 and the receiving optical fiber 32 can also move with the mounting plate 122, the position of the light beam emitted by the emitting optical fiber 31 is relatively fixed, the position of the light beam is avoided from being deviated due to different pipes or multiple detections, and the accuracy of the detection result is improved.

[0042] Further, as shown in Figures 1 to 4 As shown, in the embodiment, the first clamping jaw 11 is arranged on the mounting plate 122 through an elastic assembly 13. The elastic assembly 13 is arranged, so that the first clamping jaw 11 can be corrected in position when clamping and positioning the first pipe 91, and the clamping and positioning effect is better.

[0043] Further, as shown in Figure 4 ​As shown, in the embodiment, the elastic assembly 13 comprises a sliding rail 131, a spring 132, an elastic plunger 133 and a jaw seat 134 arranged on the mounting plate 122, the first jaw 11 is arranged on the jaw seat 134, the jaw seat 134 is slidably arranged on the sliding rail 131, one end of the jaw seat 134 is connected with the spring 132, and the other end is abutted with the elastic plunger 133. By arranging the spring 132 and the elastic plunger 133, the first jaw 11 can be elastically moved to correct the positioning of the clamping of the first pipe 91. By arranging the spring 132 at one end and the elastic plunger 133 at the other end, the spring 132 can reset the position of the first jaw 11, the elastic plunger 133 is convenient to maintain, has strong adjustability, can cooperate with the spring 132 to correct the positioning, and the correction effect is better.

Since the diameter of the outer thread is smaller than the diameter of the inner thread, when detecting, the light beam emitted by the emitting optical fiber 31 is between the outer threaded end of the first pipe 91 and the inner threaded end of the second pipe 92. When the first pipe 91 and the second pipe 92 are installed in place, the light beam emitted by the emitting optical fiber 31 is blocked by the outer threaded end of the first pipe 91, and the receiving optical fiber 32 cannot receive the light beam emitted by the emitting optical fiber 31, indicating that the first pipe 91 and the second pipe 92 are installed in place. When the first pipe 91 and the second pipe 92 are not installed in place, the light beam emitted by the emitting optical fiber 31 passes through the gap between the end face of the outer threaded end of the first pipe 91 and the end face of the inner threaded end of the second pipe 92 and reaches the receiving optical fiber 32, and the receiving optical fiber 32 can smoothly receive the light beam emitted by the emitting optical fiber 31, indicating that the first pipe 91 and the second pipe 92 are not installed in place. Of course, in other embodiments, the first pipe 91 and the second pipe 92 can also be connected in a plug-in or clamped manner, and the diameter of the connecting end of the first pipe 91 is smaller than the diameter of the connecting end of the second pipe 92, which can meet the operating conditions of the emitting optical fiber.

When detecting, the first jaw 11 is clamped at one end of the first pipe 91 in the longitudinal direction, the other end of the first pipe 91 is connected with the second pipe 92, and the second jaw 21 is clamped at the connection between the second pipe 92 and the first pipe 91 in the vertical direction (perpendicular to the plane of the paper) Figure 3 to realize the multi-degree-of-freedom constraint of the first pipe 91 and the second pipe 92, and the positioning is reliable.
