[0003] The types of disconnectors usually include knife switch, rotary disconnector, vacuum disconnector and gas insulated disconnector. During the production and assembly of disconnectors, bolts and nuts are usually used to fix the connection of disconnectors. During the tightening of the bolts and nuts on the disconnector, a mechanical arm is used to drive an electric wrench to be connected with the nut, and a nut sleeve is used to limit the end of the bolt, so as to avoid the rotation of the bolt, so that the electric wrench can drive the nut to rotate and be automatically tightened.
[0004] However, since the ends of the nut and bolt are hexagonal and the angles at which the nut and bolt are placed are different, the electric wrench and the nut sleeve cannot be connected with the nut and bolt, and when the electric wrench is directly rotated at high speed, the sleeve on the electric wrench is not connected with the nut, which can cause the sleeve and the nut to rotate at high speed and rub, resulting in damage to the sleeve and the nut, and thus having certain defects.
[0005] Therefore, an automatic assembly fastening device for disconnectors and a method for using the same are proposed to solve or alleviate the above problems. SUMMARY

A ring pressure sensor (538) is fixedly installed on the top of a fixing block (531) and is electrically connected to a control module. A support spring (533) is provided, the ends of which are pressed together with the annular pressure sensor (538) and the connector (52); A drive cylinder (534) is fixedly mounted on the top of the integrated frame (1); The extrusion plate (535) is connected to the output end of the drive cylinder (534) and is slidably sleeved inside the mounting housing (51). The specific steps include the following: Step 1: When using the automatic assembly and fastening device to tighten the bolts and nuts on the disconnect switch, the control module first controls the drive cylinder (534) to operate, so that the drive cylinder (534) drives the pressing plate (535) to move downward, so that the pressing plate (535) pushes the connecting piece (52) to move downward, so that the bolt sleeve (4) moves away from the nut sleeve (32), and then the integrated frame (1) drives the nut sleeve (32) and bolt sleeve (4) to move to the corresponding positions of the nut and bolt; Step 2: The control module controls the drive cylinder (534) to drive the extrusion plate (535) to reset, and causes the integrated frame (1) to drive the servo motor (2) and the connecting sleeve (31) to descend, so that the nut sleeve (32) is connected to the nut under the action of the limit spring (35), and the connecting piece (52) drives the bolt sleeve (4) to rise under the action of the support spring (533), so that the bolt sleeve (4) is flexibly connected to the bolt; Step 3: The ring pressure sensor (538) transmits the spring force value of the support spring (533) to the control module. The control module uses internal judgment logic to determine whether the nut sleeve (32) and bolt sleeve (4) are connected to the nut and bolt. When they are not connected, the control module controls the servo motor (2) to drive the connecting sleeve (31) to rotate at the first speed. The connecting sleeve (31) drives the nut sleeve (32) to rotate relative to the nut and bolt until the nut sleeve (32) and bolt sleeve (4) are connected to the nut and bolt. Then, the control module controls the servo motor (2) to drive the connecting sleeve (31) to rotate at the second speed, so that the connecting sleeve (31) drives the nut sleeve (32) to rotate, thus tightening the nut.
2. The method of using the automatic assembly and fastening device for disconnecting switches according to claim 1, characterized in that, The judgment logic inside the control module in step three is as follows: When the nut sleeve (32) is not mated with the nut, the nut will squeeze the nut sleeve (32) to slide toward the inside of the connecting sleeve (31), and then the limiting spring (35) can squeeze the bolt sleeve (4) and the connector (52) through the nut sleeve (32), the nut and the bolt, thereby increasing the value detected by the ring pressure sensor (538); When the bolt sleeve (4) is not connected to the bolt, the bolt will restrict the rising height of the bolt sleeve (4) and the connector (52). When the bolt sleeve (4) is connected to the bolt, the compression of the support spring (533) increases, thereby increasing the value detected by the annular pressure sensor (538). When the nut sleeve (32) and bolt sleeve (4) are connected to the nut and bolt, the nut sleeve (32) slides on the outside of the nut, and the bolt sleeve (4) is connected to the outside of the bolt. The connector (52) is only affected by the weight of the bolt and nut. The control module reads the value detected by the ring pressure sensor (538) at this time, which is the value when the nut sleeve (32) and bolt sleeve (4) are connected to the nut and bolt.
