[0032] See also Figure 1-Figure 8 The present invention provides two technical solutions, which specifically include the following embodiments:

[0033] Example 1: Reference Figure 1-Figure 8 A sprocket inspection gauge comprises a gauge body 1, a positioning frame 4 is installed inside the gauge body 1, and a telescopic slide rod 5 is slidably installed inside the positioning frame 4, a detection frame 10 is rotatably sleeved on the outer side of the telescopic slide rod 5, and a detection rod 11 is rotatably connected to the end of the detection frame 10, and a driving cylinder 6 is fixed inside the gauge body 1, and the driving cylinder 6 is an existing hydraulic cylinder, and its piston end is fixedly connected to the telescopic slide rod 5, which is used to drive the telescopic slide rod 5 to slide up and down inside the gauge body 1;

[0034] Furthermore, a detection end 16 is fixed to the end of the detection rod 11, and the detection end 16 is used to move downward with the detection frame 10 and the telescopic slide rod 5 and contact the sprocket body 2. When the detection end 16 rotates with the detection frame 10, the detection rod 11 can be forced to rotate by contacting the tooth groove of the sprocket body 2, as shown in FIG. Figure 3 The detection rod 11 and the sprocket body 2 are in the detection state. At this time, the end of the detection rod 11 is located in the tooth groove of the sprocket body 2. When the detection rod 11 rotates with the detection frame 10, the detection rod 11 can be forced to rotate along the contact position with the detection frame 10. At this time, the detection end 16 can run with the detection rod 11 and always contact the tooth edge of the sprocket body 2 to realize the detection process;

[0035] Specifically, a plurality of assembly sleeves 17 are fixed inside the detection end 16, and a plurality of inner slide bars 18 are installed inside the assembly sleeve 17. The ends of the inner slide bars 18 are rotatably connected with spherical bodies 1801 for contacting the tooth grooves of the sprocket body 2. When the detection end 16 moves with the detection rod 11, it will drive the plurality of assembly sleeves 17 and the inner slide bars 18 to move at the same time, so that the plurality of spherical bodies 1801 can move along the tooth edge of the sprocket body 2 to perform the detection operation;

[0036] Specifically, a feedback module is provided inside the detection frame 10 for monitoring the rotation frequency and rotation angle of the detection rod 11, and the feedback module includes a limit sleeve 13, and mounting frames 1301 are fixed on both sides of the limit sleeve 13, the mounting frame 1301 is slidably installed inside the detection frame 10, and the end of the mounting frame 1301 is rotatably connected to the detection rod 11, a transmission end 12 is fixed to the end of the detection rod 11, and the end of the transmission end 12 is slidably connected to the inside of the limit sleeve 13, and an adjustment end 14 is slidably assembled inside the limit sleeve 13, and a locking nut 1302 is provided on the outside of the limit sleeve 13 for locking the position of the adjustment end 14; a control panel 3 is installed on the outside of the measuring tool body 1, a feedback circuit is provided between the multiple spherical bodies 1801 and the control panel 3, and a feedback circuit is provided between the transmission end 12 and the adjustment end 14 and the control panel 3;

When the spherical body 1801 contacts the sprocket body 2, the corresponding series circuit can be connected. Therefore, when the telescopic slide bar 5 rotates at a constant speed, it is only necessary to record the number of times and the connection frequency of the corresponding series circuit to determine whether the spherical body 1801 contacts the tooth groove of the sprocket body 2 during operation, which is used to determine whether the tooth groove size meets the production requirements;

[0038] Specifically, when there is a missing or oversized tooth groove inside the sprocket body 2, the series circuit is disconnected when the spherical body 1801 moves to a specific position. Therefore, the number of times the series circuit is connected and the connection frequency are made into a curve statistical graph, which can better determine the qualified rate of the sprocket body 2.

[0039] Specifically, there is also a series circuit between the adjustment end 14 and the transmission end 12 inside the limit sleeve 13. When the detection end 16 at the end of the detection rod 11 runs along the tooth edge of the sprocket body 2, as the sprocket body 2 passes over the teeth, the detection rod 11 is forced to drive the transmission end 12 to rotate until the transmission end 12 contacts the adjustment end 14. At this time, the series circuit is connected. Therefore, when the telescopic slide bar 5 rotates at a constant speed, it is only necessary to record the number of times and the connection frequency of the corresponding series circuit to determine whether the teeth of the sprocket body 2 are too large or too small.

[0044] Similarly, the position of the adjustment end 14 can be adjusted by the cooperation of the locking nut 1302, so that it can be suitable for testing teeth of different sizes;

[0045] Similarly, through the cooperation of the limiting shaft 1101, the position of the detection rod 11 can be adjusted so that it can be suitable for detecting sprocket bodies 2 of different diameters;

[0048] Furthermore, a detection end 16 is fixed to the end of the detection rod 11, and the detection end 16 is used to move downward with the detection frame 10 and the telescopic slide rod 5 and contact the sprocket body 2. When the detection end 16 rotates with the detection frame 10, the detection rod 11 can be forced to rotate by contacting the tooth groove of the sprocket body 2, as shown in FIG. Figure 3 The detection rod 11 and the sprocket body 2 are in the detection state. At this time, the end of the detection rod 11 is located in the tooth groove of the sprocket body 2. When the detection rod 11 rotates with the detection frame 10, the detection rod 11 can be forced to rotate along the contact position with the detection frame 10. At this time, the detection end 16 can run with the detection rod 11 and always contact the tooth edge of the sprocket body 2 to realize the detection process;

[0049] Specifically, a plurality of assembly sleeves 17 are fixed inside the detection end 16, and a plurality of inner slide bars 18 are installed inside the assembly sleeve 17. The ends of the inner slide bars 18 are rotatably connected with spherical bodies 1801 for contacting the tooth grooves of the sprocket body 2. When the detection end 16 moves with the detection rod 11, it will drive the plurality of assembly sleeves 17 and the inner slide bars 18 to move at the same time, so that the plurality of spherical bodies 1801 can move along the tooth edge of the sprocket body 2 to perform the detection operation;

[0051] Specifically, the feedback circuit mentioned above is a series circuit, that is, a series circuit is provided between the plurality of inner slide bars 18 and the spherical body 1801 and the sprocket body 2, and monitoring is realized based on the existing PLC control module. When the spherical body 1801 contacts the sprocket body 2, the corresponding series circuit can be connected. Therefore, when the telescopic slide bar 5 rotates at a constant speed, it is only necessary to record the number of times and the connection frequency of the corresponding series circuit to determine whether the spherical body 1801 contacts the tooth groove of the sprocket body 2 during operation, which is used to determine whether the tooth groove size meets the production requirements;

[0052] Specifically, when there is a missing or oversized tooth groove inside the sprocket body 2, the series circuit is disconnected when the spherical body 1801 moves to a specific position. Therefore, the number of times the series circuit is connected and the connection frequency are made into a curve statistical graph, which can better determine the qualified rate of the sprocket body 2.

[0053] Specifically, there is also a series circuit between the adjustment end 14 and the transmission end 12 inside the limit sleeve 13.
