[0026] In order to facilitate those skilled in the art to understand, the structure of the present application will be further described in detail in combination with the drawings:

[0027] Embodiment one

[0028] Referring to Figures 1-5 , a centering clamp for a frame box cover plate, comprising:

[0029] A lathe body 1;

[0030] A clamping mechanism 2, the number is two, respectively set in the left and right sides of the lathe body 1;

[0031] ​​​The jacking mechanism 3 is arranged in the middle of the lathe body 1, and comprises a jacking motor 301, the telescopic end of the jacking motor 301 is connected with a jacking seat 302, a bull's eye universal wheel 303 is arranged in the middle of the jacking seat 302, an open slot is formed on both sides of the bull's eye universal wheel 303, a spring 304 is arranged in the open slot, one end of the spring 304 is fixedly connected with one end of the open slot, the other end of the spring 304 is fixedly connected with the lathe body 1, the part of the spring 304 in the open slot is provided with a flexible sleeve 305, after the jacking motor 301 drives the jacking seat 302 to rise, the spring 304 is stretched to drive the flexible sleeve 305 to expand, so that the top surface of the flexible sleeve 305 is lower than the top surface of the bull's eye universal wheel 303, after the jacking motor drives the jacking seat 302 to descend, the spring 304 is stretched to drive the flexible sleeve 305 to compress, so that the top surface of the flexible sleeve 305 is higher than the top surface of the bull's eye universal wheel 303.

[0032] In the embodiment, part of the spring 304 and the flexible sleeve 305 are arranged in the open slot, so that the top of the flexible sleeve 305 is exposed above the open slot. Therefore, the diameter of the flexible sleeve 305 can be controlled, and the height of the flexible sleeve 305 protruding above the open slot can be controlled. When the height of the flexible sleeve 305 protruding above the open slot is higher than the top end of the bull's eye universal wheel 303, the bull's eye universal wheel 303 cannot contact the corresponding frame box cover plate, at this time the frame box cover plate is fixedly supported and difficult to rotate horizontally; when the height of the flexible sleeve 305 protruding above the open slot is lower than the top end of the bull's eye universal wheel 303, the bull's eye universal wheel 303 contacts the corresponding frame box cover plate, at this time the frame box cover plate is movably supported, and the frame box can be flexibly rotated horizontally. By controlling the lifting height of the jacking motor 301 driving the jacking seat 302, the supporting mode of the jacking seat 302 to the frame box cover plate can be conveniently controlled.

[0033] The principle of changing the diameter of the flexible sleeve 305 is that the flexible sleeve 305 is arranged in the spring 304, and the two ends of the spring 304 are arranged in the lathe body and the open slot respectively. When the jacking mechanism rises, the spring 304 is stretched. When the spring 304 is stretched, the pitch of the spring 304 becomes larger, so that the flexible sleeve 305 is also stretched and expanded. At this time, the diameters of the spring 304 and the flexible sleeve 305 are both smaller. When the spring 304 is relaxed, the pitch of the spring 304 becomes smaller, the adjacent coils of the spring 304 press the flexible sleeve 305, so that the flexible sleeve 305 presents a wavy shape and rises, thereby increasing the diameter of the flexible sleeve 305.

[0034] Further, the open slot is a cylindrical slot with a side opening.

[0035] Through the structure, one end of the flexible sleeve 305 can protrude above the jacking seat 302, and the spring 304 can be stretched conveniently.

[0036] Further, the diameter of the flexible sleeve 305 in the relaxed state is 3-5mm smaller than the radius of the opening groove.

[0037] Through the structure, the flexible sleeve 305 can have a certain activity space when changing from the relaxed state to the extruded state, so that the flexible sleeve 305 is prevented from being filled with the opening groove after being extruded a little and thus being difficult to be extruded continuously.

[0038] Further, the bull's eye universal wheel 303 is embedded in the jacking seat 302, and the top end of the bull's eye universal wheel 303 protrudes 2-3mm from the jacking seat 302.

[0039] Further, the clamping mechanism 2 comprises a set of bidirectional screw rod assemblies, and the bidirectional screw rod assemblies drive a pair of clamping plates.

[0040] Further, the part of the spring 304 located in the opening groove is embedded in the flexible sleeve 305.

[0041] In the embodiment, the spring 304 is placed in the mold for preparing the flexible sleeve 305 and is integrally formed, so that the side wall of the flexible sleeve 305 covers the spring 304, and the spring 304 changes together with the flexible sleeve 305 better.
