DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0044] Therefore, the following detailed description of embodiments of the application provided in the accompanying drawings is not intended to limit the scope of the application claimed, but merely represents selected embodiments of the application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the application without creative labor fall within the scope of protection of the application.

[0045] It should be noted that similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0046] In the description of embodiments of the application, it should be noted that if the terms "upper", "lower", "horizontal", "inner" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when the product of the application is normally placed, only for the convenience of describing the application and simplifying the description, and it is not intended to indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the application.

[0057] In a second aspect, a mechanical equipment locking device replacement method is provided, and the method is performed by using the mechanical equipment locking device replacement mechanism as described above, as shown in the figure, Figure 19 The method comprises the following steps.

[0059] S102, using the external handling equipment, placing the lower part in the base replacement library while clamping the upper part with the clamping device; for example, as shown in Figures 4-10 , the upper part 8 is placed in the replacement library 7, as shown in Figure 5 , the upper part 8 includes an upper part body 801, a spring 802 and a sliding sleeve 803 are installed on the outer side of the upper part body 801, the spring 802 is connected with the sliding sleeve 803, so that the sliding sleeve 803 can be displaced up and down on the outer side of the upper part body 801, and the end of the sliding sleeve 803 close to the inside of the upper part 8 extends into the inside of the upper part 8; an elastic block 805 is installed in the inside of the upper part 8, the elastic block 805 is located in the upper middle part of the upper part 8, and opposite sides in the upper part 8 are provided with positioning columns 806 for abutting at the positioning column matching portion 9011 of the lower part 9, and a locking portion 804 is located below the positioning column 806, so that the upper middle part of the lower part 9 is located in the upper part body bottom 807 area of the upper part 8; at the same time, a square inner hole 808 is opened in the inside of the upper part 8, which is matched with the outer side of the lower part 9. As shown in Figure 8 , the lower part 9 includes a lower part body 901, which is a rectangular structure, the top of the lower part body 901 is provided with a convex head 902, the outer side of the convex head 902 has a chamfer 9021, the lower part body 901 and the convex head 902 have a groove 903 therebetween, and the bottom of the lower part body 901 is provided with a circular table 904. As shown in Figure 9 , the lower part body 901 is clamped by the external mechanical hand, so that the lower part body 901 is placed in the replacement library 7; as shown in Figure 10 , the lower part body 901 is in contact with the rotation stopping block 602, before the replacement operation starts, the rotation stopping block 602 is in the rotation stopping block retracted state 6021, and during the replacement operation, the rotation stopping block 602 is in the rotation stopping block extended state 6022.

[0060] When the lower part 9 is placed in the replacement library 7, as shown in Figure 11 and Figure 12 , the clamping device 4 first adjusts the working height by the longitudinal adjusting device 3, so that the clamping mouth of the clamping device 4 is at the same height as the outer side of the sliding sleeve 803, and then drives the clamping device 4 to displace forward by the transverse adjusting device 2, so that the clamping mouth is attached to the outer side of the sliding sleeve 803, and the sliding sleeve 803 is clamped.

After the replacement is completed, the replacement mechanism resets, thus completing the replacement work. Figures 16-18 As shown, when replacing one of the upper part 8 or the lower part 9, the steps are the same as described above. First, the lower part 9 is placed in the replacement compartment 7, and then the anti-rotation block 602 is used to hold the lower part body 901. Next, while the sliding sleeve 803 is held by the clamping device 4, the external drive device drives the upper part body 801 to rotate, thereby realizing the separation between the upper part 8 and the lower part 9.

The lower part 9 is placed in the replacement chamber 7 on the base 1, and the upper part 8 is placed in the clamping device 4 by an external handling device (such as a robotic arm). If it is necessary to replace the upper part 8 or the lower part 9, simply connect the external drive device to the top of the upper part 8 and drive the upper part 8 to rotate, thereby separating the upper part 8 from the lower part 9. At this point, the corresponding part can be replaced, such as replacing the upper part 8 or the lower part 9. During the entire replacement process, by using this replacement mechanism to clamp and replace the screw sleeve, manual labor is freed up, and the automated operation between multiple devices improves the replacement efficiency. Secondly, the lateral adjustment device 2 and the longitudinal adjustment device 3 enable the clamping device 4 and the pressing device 5 to move and adjust flexibly in three-dimensional space, improving the level of automated replacement. Furthermore, the replacement structure in this solution can be used not only for replacing screw sleeves, but also for replacing other parts with screw connections, snap-fit ​​connections, and plug-in assembly.
