[0026] Existing forklift or excavator bucket 1 such as Figure 1 As shown, a lug plate 11 is fixed on the bucket 1, and an upper mounting hole 12 and a lower mounting hole 13 are provided on the lug plate 11. Bolts are installed in the upper mounting hole 12 and the lower mounting hole 13 for mounting the bucket 1 on an excavator or a forklift. In the process of producing the bucket 1, it is usually necessary to bore the upper mounting hole 12 and the lower mounting hole 13. When the existing boring machine tool is in use, it is necessary to process each upper mounting hole 12 and each lower mounting hole 13 separately in multiple times. When processing different mounting holes, the position of the bucket 1 needs to be adjusted. The bucket 1 is usually heavy and inconvenient to move, which brings many inconveniences to the processing of the bucket 1.

[0027] To solve the above problems, see Figure 2 and Figure 3 A bucket boring tool comprises a bracket 3, the bracket 3 is provided with two parallel rotating shafts 4, the rotating shafts 4 can slide along the axial direction and rotate around their own axis, and the rotating shafts 4 are fixedly connected with a boring tool 5.

[0028] The bucket 1 is usually provided with a plurality of coaxial upper mounting holes 12 and a plurality of coaxial lower mounting holes 13. When the boring tool is used, one of the rotating shafts 4 is passed through each of the upper mounting holes 12 in turn and kept coaxial with the upper mounting holes 12, and the other rotating shaft 4 is passed through each of the lower mounting holes 13 in turn and kept coaxial with the lower mounting holes 12; the bracket 3 supports and positions the rotating shaft 4, and a boring tool 5 is arranged at the position corresponding to the mounting hole on the rotating shaft 4. The rotating shaft 4 rotates, and the upper mounting holes 12 and the lower mounting holes 13 are bored by the boring tool 5.

[0029] Compared with the prior art of processing the bucket 1 by a boring machine, the rotating shaft 4 drives multiple boring tools 5 to rotate simultaneously, so that the upper mounting holes 12 and the lower mounting holes 13 can be bored at the same time, which greatly improves the processing efficiency; the coaxial multiple upper mounting holes 12 are processed by the multiple boring tools 5 on the same rotating shaft 4, and the coaxial multiple lower mounting holes 13 are also processed by the multiple boring tools 5 on the same rotating shaft 4, which can improve the coaxiality between the upper mounting holes 12 and the coaxiality between the lower mounting holes 13 after the processing is completed, thereby improving the processing quality; and the upper mounting holes 12 and the lower mounting holes 13 can be bored synchronously, and the processing can be completed at one time, without adjusting the position of the bucket 1 during the processing process, thereby improving the convenience of processing.

[0030] A further improvement is to see Figure 4 The bracket 3 includes a base 31 and a fixed beam 32 fixedly connected to the base 31, and the rotating shaft 4 is connected to the fixed beam 32 through a bearing 33. The base 31 is connected to the bearing 33 through the fixed beam 32, and the bearing 33 is connected to the rotating shaft 3, which plays a supporting and positioning role for the rotating shaft 3, so that the rotating shaft 3 can rotate flexibly; the same rotating shaft 4 can be fixed to the base 31 through multiple bearings 33 and fixed beams 32 to improve the stability of the rotating shaft 4.

[0031] When installing the rotating shaft 4, the rotating shaft 4 is axially passed through the bearing 33, and at the same time, passed through each upper mounting hole 12 or each lower mounting hole 13, and then the boring tool 5 is installed at the corresponding mounting hole position on the rotating shaft 4, and the boring tool 5 is driven to rotate and move to perform the boring operation; after the processing is completed, the boring tool 5 on the rotating shaft 4 needs to be removed first, and then the rotating shaft 4 is axially pulled out from the mounting hole and the inside of the bearing 33 to achieve the separation of the bucket 1 and the rotating shaft 4, and then the processed bucket can be taken away.

[0032] A further improvement is to see Figure 7 The outer ring 331 of the bearing 33 is fixedly connected to the fixed beam 32, and the inner ring 332 of the bearing 33 is sleeved on the outer periphery of the rotating shaft 4 and is slidably connected to the rotating shaft 4. The outer ring 331 and the inner ring 332 of the bearing 33 are rollingly connected through balls to reduce the friction between the two, thereby reducing the resistance of the rotating shaft 4 and improving the smoothness of the rotation of the rotating shaft 4; and the rotating shaft 4 is slidably connected to the inner ring 332, so that the rotating shaft 4 can slide along its own axial direction, so that the boring cutter 5 is driven to rotate through the rotating shaft 4 and move axially along the mounting hole, thereby realizing boring processing of the mounting hole.

[0033] A further improvement is to see Figure 7The side of the rotating shaft 4 is provided with a limiting groove 42 along the axial direction, and the inner wall of the inner ring 332 is provided with a limiting key 333 that slides with the limiting groove 42. The limiting groove 42 cooperates with the limiting key 333 to achieve the limiting between the rotating shaft 4 and the inner ring 332, so that the two can rotate synchronously, prevent the wear caused by relative sliding between the two, and extend the service life of the equipment.

[0034] A further improvement is to see Figure 6 The boring tool 5 is detachably connected to the rotating shaft 4, and the rotating shaft 4 is provided with a plug-in hole 41 in a radial direction, and the boring tool 5 is plugged and matched with the plug-in hole 41. In fact, the rotating shaft 4 is also provided with a threaded hole in a radial direction and connected with the plug-in hole 41, and a set screw is arranged in the threaded hole. When the boring tool 5 is inserted into the plug-in hole 41, the set screw is tightened to fix the boring tool 5; by controlling the depth of the boring tool 5 inserted into the plug-in hole 41, the boring tool 5 can perform boring operations on mounting holes with different inner diameters, thereby improving the application range of the equipment.

[0035] A further improvement is to see Figure 6 The number of the plug holes 41 is multiple, and the plug holes 41 are spaced apart along the axial direction of the rotating shaft 4. By providing multiple plug holes 41, the boring tool 5 can adjust its position according to the spacing between the upper mounting holes 12 or the spacing between the lower mounting holes 13, so that the boring tool can be suitable for processing buckets 1 of different models.

[0036] A further improvement is to see Figure 5 A power unit 2 is provided at the end of the rotating shaft 4, and the power unit 2 is transmission-connected to the rotating shaft 4. The power unit 2 includes a base 21, and a track 24 is provided on the base 21 along the axial direction of the rotating shaft 4. The track 24 is slidably matched with a sliding seat 22. A driving motor 23 transmission-connected to the rotating shaft 4 is fixedly connected to the sliding seat 22. The sliding seat 22 is also provided with a push-pull member for controlling the sliding seat 22 to slide along the track 24.

[0037] When in use, the base 21 is fixed to the ground or to the base 31, and the push-pull member includes a lead screw 26 arranged parallel to the extension direction of the track 24, and a power motor 25 for driving the lead screw 26 to rotate. The sliding seat 22 is driven to move along the track 24 by the rotation of the lead screw 26, so that the driving motor 23 moves along the track 24. The power shaft of the driving motor 23 is fixedly connected to the rotating shaft 4, and the rotating shaft 4 is driven to rotate by the driving motor 23. At the same time, the driving motor moves along the track 24 to pull the rotating shaft 4 to slide along its own axial direction. Through the rotation and sliding of the rotating shaft 4, the boring tool 5 performs boring processing on the bucket 1; and by extending the moving distance of the sliding seat 22, the rotating shaft 4 can be automatically inserted and extracted in the bearing 33 and the mounting hole, without manual operation, thereby improving the convenience of equipment use.
