In order to prevent the cables and optical cables in the equipment from being twisted, it is necessary to set a limit protection mechanism. The limit protection mechanism currently used is a photoelectric rotary mechanism close to ±360°, which can only realize limit protection at a position close to ±360°, but there are still some turntables whose working range does not need to reach ±360° For an angle of 360°, another limit mechanism can achieve a working range greater than 360° and less than 540°, but it cannot meet the limit protection of 540°~720°. It can be seen that the existing limit mechanism has limitations in use.

因此,研发一种新的限位机构,以解除以往限位机构的局限性,成为人们亟待解决的问题。 Therefore, research and develop a kind of new limit mechanism, to remove the limitation of previous limit mechanism, become the problem that people demand to be solved urgently.

At this time, the stopper 5 stops in front of the counterclockwise reading sensor 7, and the counterclockwise limit reading sensor 7 generates a high-level signal to inform the host computer to stop the stopper 5 will act on the counterclockwise limit, the rotary body 2 rotates counterclockwise, the counterclockwise electric limit 43 in the counterclockwise limit mechanism 4 first passes the stop block 5, and when it is located above the stop block 5, it will generate High-level in-position signal. At this time, the rotary body 2 reaches the counterclockwise electric limit position. When the host computer receives the high-level in-position signal, it will control the rotary body 2 to stop rotating. However, if the electric limit position fails, the device will The second heavy mechanical limit protection is also provided, and the rotary body 2 will continue to rotate counterclockwise until the counterclockwise mechanical limit 41 in the counterclockwise limit mechanism 4 is connected to the stop block 5, and the stop block 5 blocks The rotation of the rotary body 2 is stopped. At this time, the rotary body 2 reaches the counterclockwise mechanical limit position, and the rotary body 2 is rotated clockwise. In the clockwise limit mechanism 3, the clockwise electric limit position 33, the clockwise mechanical limit position 31 and the counter The clockwise shifting block 32 passes through the outside of the stop block 5 successively without contact with the stop block 5, the rotary body 2 continues to rotate clockwise, and the clockwise shift block 42 in the counterclockwise limit mechanism 4 touches the inner side of the stop block 5, And the stop block 5 is moved outward along the chute 11, so that the stop block 5 stops in front of the clockwise interpretation sensor 6, and the clockwise interpretation sensor 6 generates a high-level signal to inform the upper computer that the stop block 5 will be clockwise. The clockwise limit works, the rotary body 2 continues to rotate clockwise, the counterclockwise mechanical limit 41 and the counterclockwise electric limit 43 in the counterclockwise limit mechanism 4 pass through the inside of the stop block 5 in turn, and do not contact the stop block 5 Contact, the rotary body 2 continues to rotate clockwise until the clockwise electric limiter 33 in the clockwise limit mechanism 3 passes above the stop block 5, generating a high-level in-position signal, at this time the rotary body 2 reaches the clockwise electric limiter position, when the upper computer receives a high-level in-position signal, the upper computer will control the rotary body 2 to stop rotating, but if the electric limit fails, the device is also equipped with a second mechanical limit protection, and the rotary body 2 will continue to rotate. Carry out clockwise rotation until the clockwise mechanical limit 31 in the clockwise limit mechanism 3 is connected to the stop block 5, and the stop block 5 hinders the rotation of the rotary body 2, and now the rotary body 2 reaches the clockwise mechanical limit bit position. The rotary limit device has double limit protection, which effectively reduces the failure rate of the device.

在本实施方案中,将第一旋转线和第二旋转线均设计为圆周线,且第二旋转线与第一旋转线的径向差值为回转体2半径的1/5-1/10,所述的径向差是指第一旋转线半径与第二旋转线半径之差。 In this embodiment, both the first rotation line and the second rotation line are designed as circular lines, and the radial difference between the second rotation line and the first rotation line is 1/5-1/10 of the radius of the rotating body 2 , the radial difference refers to the difference between the radius of the first line of rotation and the radius of the second line of rotation.

在本实施方案中,顺时针机械限位31和逆时针机械限位41均选用液压缓冲器,使用液压缓冲器具有一定的缓冲效果,降低对于停挡块对于装置的冲击。 In this embodiment, both the clockwise mechanical limiter 31 and the counterclockwise mechanical limiter 41 use hydraulic buffers, and the use of hydraulic buffers has a certain buffering effect and reduces the impact on the stop block on the device.

本实施方案提供的回转限位装置,可实现回转装置在360°+Φ的范围内转动,由于在实际使用时回转装置所需的转动范围为大于360°小于720°,因此将顺时针限位机构3与逆时针限位机构4之间夹角Φ设计为0°<Φ<360°。 The rotation limiting device provided by this embodiment can realize the rotation of the rotation device within the range of 360°+Φ. Since the rotation range required by the rotation device is greater than 360° and less than 720° in actual use, the clockwise limit The angle Φ between the mechanism 3 and the counterclockwise limiting mechanism 4 is designed to be 0°<Φ<360°.
