The main ruler 100 is a straight ruler.

[0023] Please refer to Figure 1 The first measuring jaw 200, the second measuring jaw 300 and the third measuring jaw 400 are sequentially arranged along the length direction of the main ruler 100. The first measuring jaw 200, the second measuring jaw 300 and the third measuring jaw 400 are sequentially arranged on the main ruler 100. The fourth measuring jaw 500 is mounted on the third measuring jaw 400. Figure 1 and Figure 2 The device is specifically defined as follows: the first measuring claw 200 is spaced apart from the third measuring claw 400 by a first distance a; the second measuring claw 300 is spaced apart from the third measuring claw 400 by a second distance b; and the side of the fourth measuring claw 500 away from the main scale 100 is spaced apart from the main scale 100 by a third distance c.

[0024] Take the furnace roller coupling 30 as an example, please refer to Figure 1 The left side of the coupling 30 is the motor side handle 20, and the right side of the coupling 30 is the furnace roller side handle 40. The coupling 30 has two ends, the left and right ends, and the motor side handle 20 and the furnace roller side handle 40 are respectively provided with ends that cooperate with the coupling 30. Figure 1 As shown in the figure, end face one 41, end face two 31, end face three 32 and end face four 21 are distributed from right to left in sequence. End face one 41 is a side of the end of the furnace roller side adapter 40 away from the coupling 30, end face two 31 is a side of the end of the coupling 30 that is opposite to the furnace roller side adapter 40 and away from the furnace roller side adapter 40, end face three 32 is a side of the end of the coupling 30 that is opposite to the motor side adapter 20 and away from the motor side adapter 20, and end face four 21 is a side of the end of the motor side adapter 20 and away from the coupling 30.

[0025] In specific use, take the end face 41 as the reference surface and move the third measuring claw 400 as shown in FIG. Figure 1As shown, it leans against end face one 41, the second measuring claw 300 is located on the right side of end face three 32, end face three 32 is located between the first measuring claw 200 and the second measuring claw 300, the first measuring claw 200 is located on the left side of end face four 21, and end face four 21 is located between the first measuring claw 200 and the second measuring claw 300; at the same time, the fourth measuring claw 500 is in contact with the outer peripheral surface of the end of the furnace roller side handle 40.

[0026] Taking the end face 41 as the reference plane, under the conditions of specific first distance a, second distance b and third distance c, the first distance a represents the maximum limit size of the end face four 21 and the end face one 41, the second distance b represents the minimum limit size of the end face three 32 and the end face one 41, and the third distance c represents the coaxiality error range of the joint.

[0027] During the above-mentioned specific use, it is determined whether the first measuring jaw 200 is not in contact with the end face four 21, the second measuring jaw 300 is not in contact with the end face three 32, and the main scale 100 is not in contact with the motor side; the position of the device on the circumferential direction of the coupling 30 is adjusted, and the above-mentioned determinations are performed respectively by using the device at different circumferential positions of the coupling 30. For example, detection is performed at four points, namely, the upper, lower, left, and right points of the coupling 30. When the first measuring jaw 200 is not in contact with the end face four 21, the second measuring jaw 300 is not in contact with the end face three 32, and the main scale 100 is not in contact with the motor side, it is determined that the coupling accuracy and the coupling coaxiality meet the requirements.

[0028] This device can be used to quickly detect the accuracy of the corresponding furnace roller coupling and the coaxiality of the joint, and can be used for rapid troubleshooting, which greatly shortens the measurement time, eliminates the time-consuming defect in the original detection, greatly improves work efficiency, and reduces labor intensity.

[0029] It should be noted that, when the application scenario of the furnace roller coupling 30 has been determined, the coupling accuracy and the coaxiality of the coupling are clear. Correspondingly, the first distance a, the second distance b, and the third distance c in this device are also specific values. In this case, the main scale 100 is simply understood as a straight rod.

[0030] In order to improve the applicability of the device for the structurally similar couplings 30 and the handover accuracy of different production lines, the first distance a, the second distance b and the third distance c in the device are set to be adjustable. In this case, the main ruler 100 provides a scale to assist in the active adjustment of the first distance a and the second distance b.

[0031] In some embodiments, see Figure 1 , the first measuring claw 200 is perpendicular to the main scale 100. During the specific detection, the first measuring claw 200 is parallel to the end of the motor-side handle 20.

[0032] In some embodiments, the first measuring claw 200 is fixedly connected to the main scale 100 , and the first distance a is adjusted by adjusting the position of the third measuring claw 400 on the main scale 100 .

[0033] In some embodiments, see Figure 1 The first measuring claw 200 is fixedly connected to the main ruler 100 , and the first measuring claw 200 is located at one end of the length of the main ruler 100 .

[0034] In some embodiments, see Figure 1 , the second measuring claw 300 is perpendicular to the main scale 100. During the specific detection, the second measuring claw 300 is parallel to the end of the coupling 30.

[0035] In some embodiments, see Figure 1 The second measuring jaw 300 is movably mounted on the main ruler 100. A second locking screw 320 is mounted on the second measuring jaw 300, which adjustably secures the second measuring jaw 300 to the main ruler 100. After the second measuring jaw 300 is adjusted to its proper position, the second locking screw 320 is tightened to secure the second measuring jaw 300 to a specific position on the main ruler 100.

[0036] In some embodiments, see Figure 1 The third measuring claw 400 is perpendicular to the main scale 100. During the specific detection, the third measuring claw 400 is in close contact with the end surface 141.

[0037] In some embodiments, see Figure 1 The third measuring jaw 400 is movably mounted on the main ruler 100. A third locking screw 410 is mounted on the third measuring jaw 400, which adjustably secures the third measuring jaw 400 to the main ruler 100. After the third measuring jaw 400 is adjusted to its proper position, the third locking screw 410 is tightened to secure the third measuring jaw 400 to a specific position on the main ruler 100.

[0038] In some embodiments, see Figure 1 The fourth measuring jaw 500 is movably mounted on the third measuring jaw 400. A fourth locking screw 520 is mounted on the fourth measuring jaw 500, which adjustably secures the fourth measuring jaw 500 to the third measuring jaw 400. After the distance between the fourth measuring jaw 500 and the main scale 100 is adjusted to the desired distance (i.e., the third distance c), the fourth measuring jaw 500 is secured to the specified position on the third measuring jaw 400 by tightening the fourth locking screw 520.

[0039] The device for testing the accuracy of furnace roller couplings and joint coaxiality of this embodiment is used to measure coupling accuracy and joint coaxiality. The three adjustable measuring jaws are adjusted according to the coupling accuracy and joint coaxiality requirements and secured with locking screws. The device then measures coupling accuracy and joint coaxiality using a simple measurement method. Using this device to inspect each of the furnace roller couplings 30 along the entire production line saves 5 minutes of measurement time per roller, significantly reducing the time required to measure each coupling 30. This significantly improves work efficiency.

[0040] This device adopts three adjustable measuring claws, which is suitable for measuring the accuracy of couplings 30 and joints with different accuracy requirements of different production lines; when used in the detection of furnace roller couplings 30, the reliability of furnace roller installation accuracy is improved.
