Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a tool for processing bolt holes of main link rails of lubricating crawler tracks, such as Figure 1 As shown, it includes: a base plate 1 and a sleeve end positioning structure 2 and a shaft end positioning structure 3 installed on the base plate 1;

[0027] Among them, an adjustable support mechanism 4 is provided near the sleeve end positioning structure 2 for supporting the workpiece. The sleeve end positioning structure 2 and the shaft end positioning structure 3 are detachably connected and installed on the base plate 1. The sleeve end of the chain track segment is fixed by the sleeve end positioning structure 2, and the shaft end positioning structure 3 fixes the shaft end of the chain track segment.

[0028] In specific implementation, Figure 3 As shown, the base plate 1 is provided with a fixing portion 101 for connection to a processing machine tool, a positioning pin hole 102, and a positioning block pin hole 103 for mounting the sleeve end positioning structure 2 and the shaft end positioning structure 3. The spacing between the positioning block pin hole 103 at the shaft end positioning pin 301 and the positioning block pin hole 103 at the sleeve end positioning pin 201 is consistent with the track segment pitch.

[0029] See also Figure 2-Figure 6 As shown, Figure 5As shown, the sleeve end positioning structure 2 wraps the sleeve end positioning pin shaft 201 embedded in the positioning block pin hole 103, and the sleeve end positioning pin shaft 201 is provided with a sleeve end flange 202 and a sleeve end pressure plate 203 for fixing on the base plate 1. The sleeve end flange 202 is installed on the base plate 1 by bolts. A diamond-shaped sleeve end positioning boss 204 is provided on the sleeve end flange 202, and the end of the sleeve end positioning boss 204 has a rounded transition, which is used to locate the chain track link sleeve end pin hole. The diamond-shaped setting can avoid installation difficulties caused by over-positioning, reduce auxiliary time and improve processing efficiency. The sleeve end positioning boss 204 is located at the axis center of the sleeve end flange 202 and a sleeve end mounting hole 205 is opened at the axis center. The sleeve end pressure plate 203 is installed on the sleeve end mounting hole 205. In this embodiment, the sleeve end mounting hole 205 is a threaded hole, and the sleeve end pressure plate 203 is installed and fixed by bolts.

[0030] like Figure 5 As shown, the sleeve end flange 202 corresponding to the adjustable support mechanism 4 is further provided with a slot 206 for matching the adjustable support mechanism 4. Figure 3 、 Figure 5 and Figure 6 As shown, the adjustable support mechanism 4 includes a slide groove 401 provided on the bottom plate 1 and a support block 402 sliding on the slide groove 401. Figure 2 As shown, support block 402 extends upward above slot 206 and has an inclined top surface, supporting the workpiece via support block 402. Bolts penetrate support block 402 and are threadedly connected to base plate 1. A tension spring 403 is installed between support block 402 and base plate 1. After the bolt is unthreaded, the tension spring 403 pushes support block 402 to the bolt cap.

[0031] Combine Figure 2 and Figure 4 As shown, the shaft end positioning structure 3 includes a shaft end positioning pin 301 installed in the positioning block pin hole 103, a shaft end flange 302 and a shaft end pressure plate 303 arranged on the shaft end positioning pin 301 for fixing on the base plate 1, the shaft end flange 302 is installed on the base plate 1 by bolts, and a support boss 304 extends upward from the axis center of the shaft end pressure plate 303. The diameter of the support boss 304 is smaller than the diameter of the workpiece countersink and is used to position the bottom surface of the chain track segment countersink. An axis end positioning boss 305 is provided on the axis center of the support boss 304, and the end face of the axis end positioning boss 305 is used as a guide structure by providing a rounded transition to facilitate loading and is used to position the axis end pin hole of the chain track section. An axis end mounting hole 306 is coaxially opened on the axis end positioning boss 305, and the axis end pressure plate 303 is installed on the axis end mounting hole 306. The axis end mounting hole 306 in this embodiment is a threaded hole, and the axis end pressure plate 303 is installed on the axis end mounting hole 306 by bolts.

[0032] It should be noted that when using the lubricating crawler main chain rail segment bolt hole processing tooling, the thread can be withdrawn by rotating the bolt on the support block 402 and the threaded connection with the base plate 1. During this period, the tensioning spring 403 releases elastic potential energy to drive the support block 402 to slide in the slide groove 401 to adjust the position. This method can prevent locking, reduce auxiliary time, and improve work efficiency.

[0033] During machining, the workpiece is positioned by mounting the axial end of the track link on the axial end positioning structure 3, while the sleeve end of the workpiece is mounted on the sleeve end positioning structure 2 to tighten the spring. After the workpiece is mounted, the axial end pressure plate 303 is first pressed against the workpiece axial end through the axial end mounting hole 306 and the required bolts. Then, the bolts of the support block 402 are threadedly connected to the base plate 1 to reduce the distance between the sleeve end positioning structure 2 and the support block 402, so that the upper inclined surface of the support block 402 supports the workpiece. Finally, the sleeve end pressure plate 203 is pressed against the workpiece sleeve end through the sleeve end mounting hole 205 and the required bolts. After the above process, the workpiece is compressed and subsequent machining operations are carried out.
