Detailed ways

A wire reel angle detection device for high-voltage cable reel packaging, as shown in Figure 1 and Figure 2, includes a wire reel frame 1, and the wire reel frame 1 includes a base 11 and two oppositely arranged on the base 11 The first bracket 12 and the second bracket 13, wherein the side wall of the first bracket 12 is equipped with a first rotating shaft 14, the high-voltage cable reel is sleeved on the first rotating shaft 14, and the high-voltage cable reel 8 is driven to rotate by the first rotating shaft 14;

The second bracket 13 side wall tops are equipped with a fixed bracket 2 by a hinge, and the fixed bracket 2 includes two first fixed blocks 21 and the second fixed block 22 that are arranged oppositely, between the first fixed block 21 and the second fixed block 22 tops The connecting plate 23 is vertically connected and fixed, and the first fixed block 21 is mounted on the upper part of the side wall of the second support 13 by a hinge, and the side wall of the second fixed block 22 is equipped with a second rotating shaft, and one end of the second rotating shaft is equipped with a pinion 3. After the other end passes through the second fixed block 22, an optical encoder 4 is installed. The optical encoder 4 changes the output value and sends it to the control system in real time. At the same time, the side wall of the second fixed block 22 is installed with a connecting spring 5. The other end of the connection spring 5 is installed on the second support 13, and the soft connection of the fixed support 2 is realized through the action of the connection spring 5 and the hinge, and the adjustable fixing of the pinion 3 is realized simultaneously, so that the position of the pinion 3 can be adjusted;

The middle part of the side wall of the second bracket 13 is equipped with a top shaft 6, and a top 61 is installed on the top shaft 6. At the same time, a large gear 7 is installed on the top 61. The large gear 7 meshes with the pinion 3, and the end faces of the large gear 7 are evenly distributed. Some guide shafts 71 are arranged, and annular rubber block 72 is installed and fixed on one end of some guide shafts 71, and the other end of guide shaft 71 is all installed limit blocks simultaneously, and guide shaft 71 is sleeved with limit clip spring, and one end of limit clip spring and The end face of the annular rubber block 72 is pressed and connected, and the other end is pressed and connected with the end face of the large gear 7. During the detection process, the top 61 moves forward to drive the large gear 7 to move forward, and the large gear 7 drives the guide shaft 71 and the small gear. Gear 3 moves forward simultaneously, until the annular rubber block 72 is pressed into the cable reel central hole, then the side wall outer surface of the annular rubber block 72 is pressed against the side wall of the wire reel central hole, and the ring rubber block 72 drives the guide shaft 71 to move during the pressing process, and simultaneously presses the limit spring to compress and deform until the annular rubber block 72 is pressed into the center hole of the wire reel, and passes through the gap between the wire reel and the annular rubber block 72 during the rotation of the wire reel. The frictional force drives the ring-shaped rubber block 72 to rotate, and the ring-shaped rubber block 72 drives the large gear 7 to rotate. Since the pinion 3 is fixed on the second fixed block 22, the second fixed block 22 and the second bracket 13 are connected by the connecting spring 5. Furthermore, the pinion 3 is only pressed against the big gear 7 under the pull of the connection spring 5, eliminating the gear transmission gap and making the transmission more precise, so that the big gear 7 drives the pinion 3 to rotate, and the pinion 3 drives the optical encoder 4 When rotating, the transmission accuracy will not be affected by the intermittent change of the gear transmission, and then the accuracy of the output value of the optical encoder 4 will be affected;

The specific working process of the coil angle detection device is as follows:

During the positioning process of the high-voltage wire reel, the wire reel rotates under the action of the first rotating shaft 14. At this time, during the rotation of the wire reel, the friction force between the wire reel and the annular rubber block 72 drives the ring-shaped rubber block 72 to rotate, and the ring-shaped rubber block 72 Drive the bull gear 7 to rotate, because the pinion 3 is fixed on the second fixed block 22, the second fixed block 22 and the second bracket 13 are connected by the connecting spring 5, and then the pinion 3 is only pulled by the connecting spring 5 Pressing on the large gear 7 eliminates the gear transmission gap and makes the transmission more accurate, so that the large gear 7 drives the small gear 3 to rotate, and the small gear 3 drives the optical encoder 4 to rotate, and the optical encoder 4 changes the output value in real time. Send it to the control system, and then determine the change value of the hole position angle during the rotation of the reel to ensure that the error between the actual value and the detected value is ≤0.35mm, which fully meets the accuracy requirements of the system control.
