[0031] This exemplary embodiment provides a detection device, which includes a detection component and a calibration component. As Figures 1-9 shown, Figure 1 is a schematic structural diagram of an exemplary embodiment of the detection device of the present disclosure, Figure 2 is Figure 1 a schematic structural diagram of the detection component in Figure 3 is Figure 2 a front view of the detection component in Figure 4 is Figure 2 a left view of the detection component in Figure 5 is Figure 2 a top view of the detection component in Figure 6 is Figure 1 a schematic structural diagram of the calibration component in Figure 7 is Figure 6 a front view of the calibration component in Figure 8 is Figure 6 a left view of the calibration component in Figure 9 is Figure 6Top view of the middle calibration component. The detection device may include: a detection component 1 and a calibration component 2. The detection component 1 includes: a vernier caliper 11, a fixing member 12, a support rod 13, and a positioning disk 14. The vernier caliper 11 includes a main scale 111 and a vernier scale 112, and the vernier scale 112 is slidably connected to the main scale 111; the fixing member 12 can operate in a first state and a second state. In the first state, the main scale 111 is slidably connected to the fixing member 12, and in the second state, the main scale 111 is fixedly connected to the fixing member 12; the first end of the support rod 13 is connected to the fixing member 12, and the extending direction of the support rod 13 intersects the extending direction of the main scale 111. For example, the extending direction of the support rod 13 is perpendicular to the extending direction of the main scale 111; the positioning disk 14 is connected to the second end of the support rod 13; the calibration component 2 includes: a support frame 21, a positioning ring 22, and a positioning block 23. The support frame 21 includes a base 211 and a support portion 212. The support portion 212 is fixedly connected to the base 211, and the extending direction of the support portion 212 intersects the plane where the base 211 is located. For example, the extending direction of the support portion 212 is perpendicular to the plane where the base 211 is located; the positioning ring 22 is connected to the base 211; the positioning block 23 is connected to the support portion 212. The positioning block 23 is connected to the side of the support portion 212 away from the base 211 and is connected to the side of the support portion 212 facing the positioning ring 22; wherein, the positioning disk 14 is detachably connected to the positioning ring 22, and when the positioning disk 14 is connected to the positioning ring 22, the positioning block 23 is located on the moving path of the vernier scale 112.

[0032] In this exemplary embodiment, as Figure 10As shown, it is a schematic structural diagram of the detection component for detecting the pull rod seat. When performing spatial detection on the pull rod seat 7, the spring seat 6 adjacent to the pull rod seat 7 can be used as a reference point, and whether the pull rod seat 7 meets the requirements after maintenance can be detected by measuring the distance between the surface 71 to be detected on the pull rod seat 7 and the spring seat 6. Among them, a circular groove is formed on the spring seat 6. In this exemplary embodiment, the circular groove formed by the positioning ring 22 is used to simulate the groove on the spring seat 6, and the plane on one side of the positioning block 23 facing the positioning ring 22 is used to simulate the surface 71 to be detected on the pull rod seat 7. The angle formed by the extending direction of the groove on the spring seat 6 and the plane where the surface to be detected is located is equal to the angle formed by the axial direction of the positioning ring 22 and the plane where the positioning block 23 is located. For example, the extending direction of the groove on the spring seat 6 is parallel to the plane where the surface to be detected is located, and the axial direction of the positioning ring 22 is parallel to the plane where the positioning block 23 is located. In this exemplary embodiment, the distance from the axis of the positioning ring 22 to the plane where the positioning block 23 is located can be set as the standard distance from the axis of the groove on the spring seat 6 to the plane where the surface 71 to be detected is located. Among them, the plane where the positioning block 23 is located is the plane on the side of the positioning block 23 facing away from the support portion 212. When the positioning disk 14 is connected to the positioning ring 22, the detection component 1 can be calibrated by the calibration component 2. For example, move the vernier 112 to make the vernier 112 fit with the positioning block 23, and move the main scale 111 to align the X scale of the main scale 111 with the zero scale of the vernier 112. Then, fix the main scale with the fixing member 12. Subsequently, detach the positioning disk 14 from the positioning ring 22, install the positioning disk 14 in the circular groove of the spring seat 6, move the vernier 112 to make the vernier 112 fit with the surface 71 to be detected of the pull rod seat 7, and read the reading Y of the vernier caliper. The length by which Y deviates from X is the length by which the surface 71 to be detected deviates from the standard position. Among them, X can be greater than 0.

[0033] In this exemplary embodiment, the detection component 1 can be recalibrated multiple times by the calibration component 2. For example, after calibrating the detection component 1 once by the calibration component 2, the positioning disk 14 can be detached from the positioning ring 22, and then the positioning disk 14 can be re-fixed in the positioning ring 22 to recalibrate the detection component 1. The recalibration can include: moving the vernier 112 to make the vernier 112 fit with the positioning block 23, reading the reading of the vernier caliper, and detecting whether the read reading deviates from the X value. When the differences between the readings obtained from multiple recalibrations and the X value are all less than the threshold, the first calibration can be considered accurate. In this exemplary embodiment, the detection component 1 can be recalibrated 5 times by the calibration component 2.

[0034] In this exemplary embodiment, the fixing member 12 may be provided with an opening matching the support rod 13, and the positioning plate 14 may also be provided with an opening matching the support rod 13. The opening on the fixing member 12 may be interference-connected with the first end of the support rod 13, and the opening on the positioning plate 14 may be interference-connected with the second end of the support rod 13. For example, the fixing member 12 and the support rod 13, and the positioning plate 14 and the support rod 13 may be assembled by liquid nitrogen cold assembly.

[0035] In this exemplary embodiment, when forming the calibration component 2, the positioning ring 22 and the positioning block 23 can be first installed on the support frame 21, and then the positioning ring 22 and the positioning block 23 can be finely processed so that the distance from the axis of the positioning ring 22 to the plane where the positioning block 23 is located is equal to the above-mentioned standard distance. In this exemplary embodiment, the distance from the axis of the positioning ring 22 to the plane where the positioning block 23 is located can be detected by a three-dimensional coordinate measuring machine.

[0036] In this exemplary embodiment, Figures 1-9 As shown, the fixing member 12 may include: a fixing body 121, a pressure cover 122, and a first screw 31. A slide groove is formed on the fixing body 121, and the main scale 111 is slidably installed in the slide groove. When the main scale 111 is slidably installed in the slide groove, the size of the main scale 111 in the depth direction of the slide groove is greater than the depth of the slide groove. For example, the size of the main scale 111 in the depth direction of the slide groove is 0.5 mm greater than the depth of the slide groove. The pressure cover 122 is located on the side of the main scale 111 away from the slide groove; the first screw 31 is threadedly connected to the pressure cover 122 and the fixing body 121 along the depth direction of the slide groove. Among them, the first screws 31 can be four. In this exemplary embodiment, the fixing member 12 can be operated in the first state or the second state by loosening or tightening the first screw 31. For example, when the first screw 31 is tightened, the pressure cover 122 can fasten the main ruler 111 in the slide groove; when the first screw 31 is loosened, the main ruler 111 can slide along the slide groove in its extension direction.

[0037] In this exemplary embodiment, Figures 1-9 As shown, a threaded hole is formed on the side wall of the slide slot, and the fixing member 12 further includes a second screw 32, which can be threadedly connected to the threaded hole on the side wall of the slide slot. The second screw 32 can further tighten the main ruler 111 in the lateral direction.

[0038] In this exemplary embodiment, Figures 1-9As shown, the wear resistance of the positioning ring 22 can be stronger than that of the support frame 21, and the wear resistance of the positioning block 23 can be stronger than that of the support frame 21. In this exemplary embodiment, the positioning ring 22 and the positioning block 23 are formed of materials with relatively high wear resistance, so as to improve the calibration accuracy of the calibration assembly 2 and extend the service life of the calibration assembly 2 at the same time. For example, the positioning ring 22 and the positioning block 23 can be formed of high-strength steel. After rough machining, the positioning ring 22 and the positioning block 23 can be quenched to make them wear-resistant. In this exemplary embodiment, the wear resistance of the positioning disk 14 and the vernier 112 in the detection assembly 1 can be stronger than that of other components in the detection assembly 1. Similarly, the positioning disk 14 and the vernier 112 can be formed of high-strength steel, and other structures such as the support rod 13 in the detection assembly 1 can be formed of stainless steel.

[0039] In this exemplary embodiment, as Figures 1-9 shown, the positioning disk 14 may include: a first disk body 141 and a second disk body 142. The first disk body 141 is connected to the second end of the support rod 13, and the radius of the first disk body 141 may be greater than the radius of the inner ring of the positioning ring 22; the second disk body 142 is connected to one end of the first disk body 141 away from the support rod 13, and the second disk body 142 can be matingly sleeved inside the positioning ring 22. When the second disk body 142 is sleeved inside the positioning ring 22, the first disk body 141 may abut against the upper end of the positioning ring 22.

[0040] In this exemplary embodiment, as Figures 1-9 shown, the support frame 21 may further include: a support ring 213, a third screw 33, and a positioning pin 4. The support ring 213 is fixed to the base 211, and the positioning ring 22 is located on the side of the support ring 213 away from the base 211; the third screw 33 is threadedly connected to the positioning ring 22 and the support ring 213 along the distribution direction of the positioning ring 22 and the support ring 213; the positioning pin 4 is pin-connected to the positioning ring 22 and the support ring 213 along the distribution direction of the positioning ring 22 and the support ring 213. The third screw 33 and the positioning pin 4 can fixedly connect the positioning ring 22 and the support ring 213. The support ring 213 can adjust the height of the positioning ring 22.

[0041] In this exemplary embodiment, as Figures 1-9 shown, the support portion 212 and the positioning block 23 are formed with a slot 5 at one end away from the base 211. When the positioning disk 14 is connected to the positioning ring 22, the slot 5 is located on the sliding path of the main scale 111, so that when the main scale 111 slides relative to the fixing member 12, it can be partially located inside the slot 5.

[0042] In this exemplary embodiment, as Figures 1-9As shown, the vernier 112 may include: a sliding sleeve 1121 and a blocking portion 1122. The sliding sleeve 1121 is sleeved on the main scale 111; the blocking portion 1122 is connected to the sliding sleeve. When the positioning disk 14 is connected to the positioning ring 22, the positioning block 23 is located on the sliding path of the blocking portion.

[0043] In this exemplary embodiment, as Figures 1-9 shown, the support portion 212 may include: a first support plate 2121 and a second support plate 2122. The first support plate 2121 is fixedly connected to the base 211. When the positioning disk 14 is connected to the positioning ring 22, the plane where the first support plate 2121 is located may intersect with the extending direction of the main scale 111. For example, the plane where the first support plate 2121 is located may be perpendicular to the extending direction of the main scale 111. The positioning block 23 may be connected to one side of the first support plate 2121 facing the positioning ring 22; the second support plate 2122 may be fixedly connected to the base 211 and the first support plate 2121. The plane where the second support plate 2122 is located may intersect with the plane where the first support plate 2121 is located. For example, the plane where the second support plate 2122 is located may be perpendicular to the plane where the first support plate 2121 is located. The second support plate 2122 may be a right trapezoid. The long bottom of the second support plate 2122 may be fixedly connected to the base 211, and the right-angled side of the second support plate 2122 may be fixedly connected to the first support plate 2121. This setting can improve the overall strength of the support portion 212.
