DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0023] In the description of the embodiments of the present invention, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. indicate an orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use, it is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0024] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0025] With the continuous improvement of the market's requirements for the quality of processed products and users' higher requirements for product quality, the automatic locking of disconnector equipment is particularly important, not only to reduce labor costs, but also to ensure the effect and quality of screw locking.

[0026] At present, when installing screws on disconnector equipment, operators tighten them with wrenches. During the installation process, the screw structure is too small and the wrench cannot tighten the screws into place at one time, making the installation process cumbersome. In order to improve the installation efficiency, through long-term observation and research, it is found that the use of sleeves to install screws can improve the work efficiency to a certain extent. In this case, the installation of screws is carried out with screw sleeves; however, after long-term installation operations, the screw sleeves will wear out, resulting in the inability to effectively cooperate with the screws. When replacing the screw sleeves, it is necessary to use multiple devices and multi-person collaboration to complete the replacement, which increases the replacement cost and fails to achieve the purpose of reducing costs and increasing efficiency.

[0027] In order to solve the above technical defects, the inventor provides a mechanism and method for replacing a locking device of a mechanical equipment.

[0029] When replacing the screw sleeve, the screw sleeve can be divided into an upper part 8 and a lower part 9. By placing the lower part 9 in the replacement library 7 on the base 1, the upper part 8 is placed in the clamping device 4 through an external handling device (handling equipment such as a manipulator). If the upper part 8 or the lower part 9 needs to be replaced, it is only necessary to connect the external driving device to the top of the upper part 8 through an external driving device, and drive the upper part 8 to rotate through the external driving device, so as to achieve the separation of the upper part 8 and the lower part 9. At this time, the corresponding parts can be replaced, such as replacing the upper part 8 or replacing the lower part 9; during the entire replacement process, the screw sleeve is clamped and replaced by using the replacement mechanism, which liberates manual labor, and at the same time, multiple devices are automated to improve the replacement efficiency. Secondly, the setting of the lateral adjustment device 2 and the longitudinal adjustment device 3 enables the clamping device 4 and the pressing device 5 to be flexibly moved and adjusted in three-dimensional space, thereby improving the level of automated replacement.

[0030] like Figure 1 and Figure 2 As shown, a mounting opening is provided in the middle of the base 1, and a longitudinal adjustment device 3 is vertically arranged in the mounting opening and connected to the clamping device 4 through a pressing device 5, wherein the longitudinal adjustment device 3 is fixedly connected to the pressing device 5, and its driving end is fixedly connected to the clamping device 4, and is used to drive the clamping device 4 to rise and fall; a pressing opening is provided at one end of the pressing device 5, and the pressing opening is a structure with one end open and the other end blocked, and the open end of the pressing opening faces the replacement storehouse 7, and the other end of the pressing device 5 is connected to the lateral adjustment device 2, and the front and rear displacement of the pressing device 5 is realized through the lateral adjustment device 2, and an elastic anti-rotation device 6 is provided in the pressing opening. The clamping device 4 is a plate-like structure, and a clamping opening is provided at one end of the clamping device 4 facing the replacement storehouse 7, and the clamping opening is located above the pressing opening and axially coincides with the pressing opening. It can be seen from the figure that the clamping opening has the same structure as the pressing opening, and both are structures with one end blocked and the other end open.

[0031] In this scheme, if Fig.10 As shown, the elastic anti-rotation device 6 includes a spring pressure plate 601 and a anti-rotation block 602, the spring pressure plate 601 cooperates with the anti-rotation block 602, and the cross-section of the end of the anti-rotation block 602 is arc-shaped; wherein, when the anti-rotation block 602 is not started, the anti-rotation block 602 is in a retracted state; when the upper part 8 and the lower part 9 are both placed on the replacement mechanism, the clamping device 4 clamps the upper part 8, the anti-rotation block 602 is started, the anti-rotation block 602 is in an extended state, and the extended part of the anti-rotation block 602 abuts against the outside of the lower part 9, limiting the rotation of the lower part 9, while the upper part 8 is rotated by the drive of an external driving device, the upper part 8 is in a rotating state, and the lower part 9 is in a stationary state; finally, affected by the rotational force, the upper part 8 is separated from the lower part 9, and the corresponding parts can be replaced according to the operating conditions.

[0032] In this solution, the lateral adjustment device 2 is preferably a linear motor, and the longitudinal adjustment device 3 is preferably a cylinder, but the specific product selection is not limited to this solution and can be selected based on cost adaptability.

[0033] In a second aspect, a method for replacing a locking device of a mechanical device is provided, wherein the method is performed using the above-mentioned mechanism for replacing a locking device of a mechanical device, such as Fig.19 As shown, including: S101, move the upper part and the lower part to be replaced to the top of the base; illustratively, Figure 3 As shown, the upper part 8 and the lower part 9 are clamped and moved to the top of the replacement mechanism by an external manipulator; wherein the axial direction of the upper part 8 coincides with the axial direction of the clamping device 4 and the pressing device 5, and the axial direction of the lower part 9 coincides with the axial direction of the replacement library 7. Since the axial direction of the replacement library 7 coincides with the axial direction of the clamping device 4, the upper part 8 and the lower part 9 can be assembled together.

[0034] S102, using external handling equipment, placing the lower part in the base replacement warehouse, so that the clamping device clamps the upper part; illustratively, Figure 4-10 As shown, the upper part 8 is placed in the replacement library 7, as shown in FIG. Figure 5As shown, the upper part 8 includes an upper part body 801, on the outer side of which a spring 802 and a sleeve 803 are installed, the spring 802 is connected to the sleeve 803 so that the sleeve 803 can move up and down on the outer side of the upper part body 801, and the end of the sleeve 803 close to the interior of the upper part 8 extends toward the interior of the upper part 8; an elastic block 805 is installed inside the upper part 8, and the elastic block 805 is located in the middle and upper part of the upper part 8, and positioning columns 806 are provided on opposite sides of the upper part 8, and the positioning columns 806 are used to abut against the positioning column matching part 9011 of the lower part 9, and the locking part 804 is located below the positioning columns 806, so that the middle and upper part of the lower part 9 is located in the bottom 807 area of ​​the upper part body of the lower part 8; at the same time, a square inner hole 808 is opened inside the upper part 8, and the square inner hole 808 is adapted to the outer side of the lower part 9. As shown Figure 8 As shown, the lower part 9 includes a lower part body 901, which is a rectangular structure. A convex head 902 is installed on the top of the lower part body 901. The outer side of the convex head 902 has a chamfer 9021. There is a groove 903 between the lower part body 901 and the convex head 902. A round table 904 is installed at the bottom of the lower part body 901. Fig. 9 As shown, an external manipulator is used to clamp the lower part body 901, so that the lower part body 901 is placed in the replacement library 7; Fig.10 As shown, the lower part body 901 is in contact with the stop block 602. Before the replacement operation is started, the stop block 602 is in the stop block retracted state 6021. During the replacement operation, the stop block 602 is in the stop block extended state 6022.

[0035] When the lower part 9 is placed in the replacement library 7, as shown in FIG. Fig.11 and Fig.12 As shown, the clamping device 4 is first adjusted to a working height through the longitudinal adjustment device 3 so that the clamping opening of the clamping device 4 can be at the same height as the outer side of the sliding sleeve 803, and then the clamping device 4 is driven to move forward through the transverse adjustment device 2 so that the clamping opening and the outer side of the sliding sleeve 803 are fitted together to clamp the sliding sleeve 803.

[0036] S103, operate the longitudinal adjustment device to adjust the positional relationship between the upper part and the lower part, so that the upper part and the lower part are in an unlocked or locked state. Figure 13-Figure 18 As shown, after the sliding sleeve 803 is clamped, if the upper part 8 and the lower part 9 are replaced, as shown in FIG. Figure 13-Figure 15As shown, at this time, the replaced upper part 8 is pressed downwards, so that the replaced upper part 8 and the replaced lower part 9 are installed together; during the installation process, the lower part body 901 is located in the square inner hole 808, and the protrusion 902 cooperates with the elastic block 805, and the two positioning columns 806 are against the groove 903, so that the upper part 8 and the lower part 9 are in a locked state. After the replacement is completed, the replacement mechanism is reset, thereby completing the replacement work. Figure 16-18 As shown, when replacing one part of the upper part 8 or the lower part 9, the lower part 9 is first placed in the replacement library 7, and then the lower part body 901 is clamped by the stop block 602; next, while the sliding sleeve 803 is clamped by the clamping device 4, an external driving device drives the upper part body 801 to rotate, thereby realizing the separation between the upper part 8 or the lower part 9.

[0037] To sum up, when replacing the screw sleeve, the screw sleeve can be divided into an upper part 8 and a lower part 9. The lower part 9 is placed in the replacement library 7 on the base 1, and the upper part 8 is placed in the clamping device 4 through an external handling device (such as a manipulator or other handling device). If the upper part 8 or the lower part 9 needs to be replaced, it is only necessary to connect the external driving device to the top of the upper part 8 through an external driving device, and drive the upper part 8 to rotate through the external driving device, so as to realize the separation of the upper part 8 and the lower part 9. At this time, the corresponding parts can be replaced, such as replacing the upper part 8 or replacing the lower part 9. During the entire replacement process, the screw sleeve is clamped and replaced by utilizing the replacement mechanism, thereby freeing up manual labor, and at the same time, the automation operation between multiple devices improves the replacement efficiency. Secondly, the setting of the lateral adjustment device 2 and the longitudinal adjustment device 3 allows the clamping device 4 and the pressing device 5 to be flexibly moved and adjusted in three-dimensional space, thereby improving the level of automated replacement; and the replacement structure in this scheme can not only be used to replace the screw sleeve, but also can be used to replace other parts with threaded, clamped and plug-in assembly.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit its protection scope. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that after reading the present invention, those skilled in the art can still make various changes, modifications or equivalent substitutions to the specific implementation methods of the invention, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the invention.
