[0030] Specifically, the sleeve hole positioning mechanism 200 includes a sleeve hole positioning pin 201 and a sleeve hole positioning column 202; the pin hole positioning mechanism 300 includes a pin hole positioning pin 301 and a pin hole positioning column 302; the sleeve holes and pin holes at both ends of the rail chain link 400 are respectively sleeved on the sleeve hole positioning pin 201 and the pin hole positioning pin 301, and are respectively tightened and aligned by the sleeve hole positioning column 202 and the pin hole positioning column 302, which is simple and convenient to operate and can greatly reduce the time consumption of measurement and marking.

[0031] In some of the embodiments, Figure 1 , Figure 3 and Figure 5As shown, the support base 100 is mainly composed of a bottom plate 101, a sleeve hole side plate 102 and a pin hole side plate 103. The sleeve hole side plate 102 and the pin hole side plate 103 are respectively vertically arranged at both ends of the bottom plate 101, and their outer walls and both side end surfaces are flush with the bottom plate 101.

[0032] Specifically, the bottom plate 101, the sleeve hole side plate 102 and the pin hole side plate 103 are all made of steel plates, and the sleeve hole side plate 102 and the pin hole side plate 103 are respectively fixed to the two ends of the bottom plate 101 by welding, and the whole is connected into an integrated structure. Or, as needed, in order to facilitate disassembly and replacement, the sleeve hole side plate 102 and the pin hole side plate 103 are respectively detachably mounted on the two ends of the bottom plate 101 by bolts.

[0033] In some of the embodiments, Figure 5 As shown, based on the structural form of the sleeve holes and pin holes at the left and right ends of the rail link 400, in order to achieve the limit fixation of the sleeve holes and pin holes at the right ends, the height of the sleeve hole positioning pin 201 is lower than the height of the pin hole positioning pin 301, and the lower ends thereof are vertically fixed to the left and right ends of the support base 100 in an interference fit manner.

[0034] The diameter of the sleeve hole positioning pin 201 is larger than the diameter of the pin hole positioning pin 301, and the diameter of the sleeve hole positioning pin 201 is slightly smaller than the hole diameter of the sleeve hole, and the two are arranged coaxially with clearance fit during installation. Similarly, the diameter of the pin hole positioning pin 301 is slightly smaller than the hole diameter of the pin hole, and the two are arranged axially with clearance fit during installation.

[0035] To achieve locking and fixing between the hole positioning pin 201 and the hole positioning column 202, the left end of the rail chain link 400 is pressed, the hole positioning column 202 is loosely sleeved on the upper end of the hole positioning pin 201, and the hole bolt 204 is used to lock and connect.

[0036] Similarly, to lock and fix the real pin hole locating pin 301 and the pin hole locating column 302, the right end of the rail chain link 400 is pressed, the pin hole locating column 302 is loosely sleeved on the upper end of the pin hole locating pin 301, and the pin hole bolt 304 is used to lock and connect.

[0037] In addition, if Figure 5 As shown, the sleeve hole positioning column 202 and the pin hole positioning column 302 are both hollow cylindrical sleeve structures, and the outer peripheral edge positions of the bottom ends thereof are respectively provided with inclined surfaces matching with the sleeve hole and the pin hole.

Correspondingly, the upper end of the pin hole bolt 304 is pressed and connected with the top of the pin hole positioning column 302 through the pin hole pressing block 303, and the lower end is threadedly connected to the top of the pin hole positioning pin 301.

[0039] Specifically, in order to facilitate the disassembly of the sleeve hole positioning mechanism 200 and the pin hole positioning mechanism 300 so as to quickly replace the rail chain link 400, the sleeve hole pressure plate 203 and the pin hole pressure block 303 both adopt circular open washers for easy removal, and their diameters are slightly smaller than the diameters of the sleeve hole positioning column 202 and the pin hole positioning column 302, respectively, to achieve the purpose of tightening the sleeve hole positioning column 202 and the pin hole positioning column 302.

[0040] In some of the embodiments, Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the hole positioning mechanism 200 also includes a hole surface head 205 arranged on the outside of the hole positioning pin 201. The hole surface head 205 is one and adopts a hexagon socket screw.

The height of the hole face head 205 can be adjusted up and down by bolts and screw holes. The top end of the hole face head 205 is abutted against the machined positioning point at the bottom of the hole end of the rail chain link 400.

[0042] Correspondingly, the pin hole positioning mechanism 300 further includes a pin hole surface header 305 disposed at an outer position of the pin hole positioning pin 301 . There are two pin hole surface headers 305 , which are centrally symmetrical with respect to the pin hole positioning pin 301 .

[0043] The lower end of the pin hole face head 305 is a threaded structure, and is installed in the corresponding screw hole on the support base 100 in an adjustable threaded manner, and the height of the pin hole face head 305 can be adjusted up and down by the bolt and the screw hole. The top of the pin hole face head 305 is designed as an arc-shaped spherical structure, which is consistent with the shape of the machined positioning point position on the rail link 400, that is, the top of the pin hole face head 305 is abutted and connected with the positioning point at the bottom of the pin hole end on the rail link 400.

The sleeve hole surface heads 205 are connected to the bottom plate 101 through bolt holes, and the height of the sleeve hole surface heads 205 can be adjusted up and down through the screw holes. When in use, the heights of the two pin hole surface heads 305 are adjusted to be consistent, and the height difference of one pin hole positioning pin 301 is adjusted according to the requirements of the drawing;

[0046] The sleeve hole positioning column 202 and the sleeve hole positioning pin 201 are ensured to be concentric by a clearance fit, and the pin hole positioning column 302 and the pin hole positioning pin 301 are ensured to be concentric by a clearance fit, and the rail chain link 400 is placed on the sleeve hole surface head 205 and the pin hole surface head 305 through the sleeve hole positioning pin 201 and the pin hole positioning pin 301, and the positions of the sleeve hole surface head 205 and the pin hole surface head 305 are consistent with the subsequent machining positioning point;
