[0039] The shaft column grinding mechanism 2 includes a shaft column mounting base 21, three layered grinding discs 28, a grinding column 29, and a column adjustment assembly;

[0040] The shaft column mounting base 21 is located below the shaft column pressure plate 12, and three layered grinding discs 28 and pressure plate 23 are stacked from bottom to top inside the shaft column pressure plate 12.

[0041] The upper wall of the pressure plate 23 has several circular outward radiating shaft column placement slots 24;

[0042] Two grinding columns 29 are movably set at the positions of the three layered grinding discs 28 and the corresponding shaft column placement slots 24;

[0043] The grinding columns 29 of the three layered grinding discs 28 corresponding to the same shaft column placement slot 24 are distributed on both sides of the shaft column to be ground, and each group of grinding columns 29 is controlled by the column adjustment assembly.

[0044] The three layered grinding discs 28 have different grinding posts 29 with different grit sizes;

[0045] In use, multiple shafts to be polished are placed in multiple shaft placement slots 24, and the polishing pillars 29 in the three layered polishing discs 28 are pushed up by the pillar adjustment assembly to a V-shaped distribution state that does not contact the shafts to be polished.

[0046] The shaft column pressure plate 12 presses on the pressure plate 23 and rotates at high speed, driving all the shaft columns to be ground to rotate at high speed in the shaft column placement groove 24.

[0047] According to the requirements, the corresponding grit grinding column 29 is pulled to contact the shaft column to be ground by adjusting the column assembly. Grinding is carried out by using different grit grinding columns 29 in sequence, and different grit grinding is completed in sequence without changing or disassembling the parts.

[0048] By integrating the shaft column pressure plate 12 and the shaft column grinding mechanism 2 into the working area of ​​the grinding machine tool 11, the centralized operation of shaft column grinding is realized, improving the space utilization and ease of operation of the equipment;

[0049] The combined design of the layered grinding disc 28 and the adjusting column assembly supports multi-stage, adjustable grinding processes to adapt to different grit requirements and avoid efficiency loss caused by frequent parts replacement.

[0050] The vertical arrangement of the shaft mounting base 21 and the shaft pressure plate 12, combined with the stacking structure of the pressure plate 23, ensures that the shaft maintains stable rotation during the grinding process and reduces the risk of displacement.

[0051] The layout of the radiating shaft column placement slots 24 can accommodate multiple shaft columns at the same time, enabling batch grinding operations and improving production efficiency;

[0052] The symmetrical design of two grinding pillars 29 in each group allows for uniform grinding on both sides of the shaft pillar, ensuring consistent surface treatment.

[0053] The grinding machine tool 11 is also equipped with a multi-axis adjustment component 14. The assembly end of the multi-axis adjustment component 14 is fixedly installed with a drive plate component 13. The shaft column pressure plate 12 is fixed on the rotating shaft end of the drive plate component 13. The diameter of the shaft column pressure plate 12 is larger than the diameter of the ring formed by all the shaft column placement slots 24, and smaller than the diameter of the shaft column mounting base 21. The shaft column pressure plate 12 and the shaft column mounting base 21 are parallel to each other.

[0054] The shaft grinding mechanism 2 also includes an assembly base plate 22, which is fixed to the bottom of the shaft mounting base 21. The diameter of the assembly base plate 22 is larger than that of the shaft mounting base 21. Multiple bolts pass through the assembly base plate 22 to fix the shaft mounting base 21 in the working area of ​​the grinding machine tool 11 at a position that matches the shaft pressure plate 12.

[0055] The three layered polishing discs 28 include a polishing top disc 281, a polishing middle disc 282, and a polishing bottom disc 283, which are arranged from bottom to top, and each corresponding polishing column 29 in the three layered polishing discs 28 is movably connected thereto, and the polishing column 29 is in tangential contact with the outer wall of the shaft column to be polished in the running state.

[0056] The polishing columns 29 with different mesh numbers are combined to support the continuous process from rough polishing to fine polishing, and the multi-stage polishing can be completed without disassembling parts, thereby improving the processing efficiency and surface quality.

[0057] The V-shaped distribution state avoids initial contact damage to the shaft column and reserves space for the gradual advancement of the subsequent polishing columns 29, thereby ensuring the stability of the polishing process.

[0058] The polishing columns 29 in the polishing bottom disc 283 are located at the bottom of the two sides of the shaft column to be polished, the polishing columns 29 in the polishing top disc 281 are located at the lower two sides of the middle of the shaft column to be polished, and the polishing columns 29 in the polishing middle disc 282 are located between the polishing bottom disc 283 and the polishing top disc 281.

[0059] The adjusting column assembly includes a control box 36, and the adjusting column assembly is provided with a plurality of groups, each group of polishing columns 29 corresponding to two groups of adjusting column assemblies for simultaneously controlling the same group of polishing columns 29 from both ends, and all adjusting column assemblies in the three layered polishing discs 28 are in communication with each other and controlled by the same pressure supply end.

[0060] The control box 36 is internally fixedly provided with two stamping boxes 42, the two ends of the stamping box 42 are provided with adjusting column arms 37, and the two adjusting column arms 37 face opposite directions, the control box 36 is connected with a pressure supply pipe 31, one end of the pressure supply pipe 31 inside the control box 36 is connected with two distribution pipes 41, and the two distribution pipes 41 are connected with the stamping boxes 42, respectively.

[0061] Through the dynamic adjustment of the adjusting column assembly, the process flow of “one-time clamping and multi-stage polishing” is realized, the part replacement and equipment downtime are reduced, and the production efficiency and processing precision are significantly improved.

[0062] One end of the two adjusting column arms 37 inside the control box 36 is provided with a limiting plate 43 and a pull column spring 44, one end of the two adjusting column arms 37 away from the stamping box 42 is fixedly provided with a stress block 35, the inside of the stress block 35 is provided with a bearing 34, the inside of the bearing 34 is provided with a rotating column 33 fixedly connected with both ends of the polishing column 29, and the bearing 34 has a certain resistance to the rotation of the polishing column 29.

[0063] The outer wall of the shaft column placement base 21 is fixedly provided with three liquid injection heads 26 and one suction head 25. The three liquid injection heads 26 respectively correspond to the pressure supply pipes 31 in the three layered polishing discs 28. The suction head 25 is connected with a plurality of slag suction pipes 27. The ends of the slag suction pipes 27 away from the suction head 25 extend to the lowermost position of the shaft column placement grooves 24.

[0064] The layout of the liquid injection heads 26 and the suction head 25, combined with the design that the slag suction pipes 27 extend to the bottom of the shaft column placement grooves 24, realizes timely suction and cleaning of the polishing residues, reduces dust pollution, and guarantees the cleanliness and operation safety of the working area.

[0065] The outer wall of the polishing column 29 is fixedly sleeved with a polishing rubber sleeve 32. The space between the polishing rubber sleeve 32 and the polishing column 29 is filled with liquid. The outer wall of the polishing rubber sleeve 32 is a polishing layer.

[0066] The liquid filling design of the polishing rubber sleeve 32 provides a flexible contact effect, protects the surface of the shaft column and improves the polishing uniformity. The setting of the polishing layer ensures efficient polishing performance. At the same time, the flexible characteristics of the liquid filling can adapt to the polishing requirements of the shaft column edge, improving the overall polishing quality.

[0067] In use, the staff needs to place the shaft column placement base 21 in the working area of the polishing machine bed 11, use a plurality of bolts to pass through the assembly plate 22 and tighten in the working area of the polishing machine bed 11 to fix it, and connect the pressure supply pump with the three liquid injection heads 26 and connect the dust suction pump with the suction head 25.

[0068] Then, a plurality of shaft columns to be polished are placed in the plurality of shaft column placement grooves 24 at one time. At this time, the shaft columns to be polished protrude from the opening position of the shaft column placement grooves 24. Then, the shaft column pressure plate 12 is adjusted to be opposite to the upper side of the shaft column placement base 21 by the automatic control of the multi-shaft positioning member 14. Then, the shaft column pressure plate 12 is pushed to be above the plurality of shaft columns to be polished by the driving disc member 13, and is rotated at high speed, so as to drive all the shaft columns to be polished to rotate in the shaft column placement grooves 24.

[0069] When the shaft column pressure plate 12 is lowered, the system first controls the polishing columns 29 in the polishing bottom disc 283 to approach the shaft columns to be polished, and makes the polishing rubber sleeves 32 tightly press against the outer walls of the shaft columns to be polished. At the same time, the polishing columns 29 in the polishing top disc 281 and the polishing middle disc 282 are controlled to move away from the outer walls of the shaft columns to be polished. At this time, the shaft columns to be polished rotate at high speed, and the polishing layers on the polishing rubber sleeves 32 polish the shaft columns to be polished.

[0070] When the polishing columns 29 in the polishing bottom disc 283 complete polishing of the shaft columns to be polished, the polishing columns 29 are controlled to move away from the shaft columns to be polished, and the polishing columns 29 in the polishing middle disc 282 are controlled to approach the shaft columns to be polished, so as to polish the shaft columns to be polished again.

[0071] When the polishing column 29 in the middle polishing disc 282 finishes polishing the shaft column to be polished, the polishing column 29 is controlled to move away from the shaft column to be polished, and the polishing column 29 in the top polishing disc 281 is controlled to move close to the shaft column to be polished, so as to polish three times;

[0072] The polishing sequence of the polishing columns 29 in the top polishing disc 281, the middle polishing disc 282 and the bottom polishing disc 283 is not fixed, and can be changed at will according to actual needs;

[0073] The polishing columns 29 in the top polishing disc 281, the middle polishing disc 282 and the bottom polishing disc 283 are all located in the middle and lower part of the shaft column to be polished, so that the displacement of the shaft column to be polished will not be caused when the polishing columns 29 in the three discs press the shaft column to be polished.

[0074] The liquid is stored between the polishing sleeve 32 and the polishing column 29, so as to achieve the flexibility of the polishing sleeve 32. When the polishing sleeve 32 presses the shaft column to be polished, the part not pressed will be bulged, so as to wrap the shaft column to be polished and polish the top edge of the shaft column to be polished.

[0075] When the shaft column to be polished is polished, the dust suction pump works at the same time, and the polishing residues are sucked away through the suction head 25 and the plurality of slag suction pipes 27;

[0076] When the system controls the polishing column 29 in the corresponding layered polishing disc 28, the liquid injection and pressure increase are performed in the corresponding liquid injection head 26 through the pressure supply pump, so that the hydraulic pressure in the stamping box 42 is increased, the adjusting column arm 37 is extended outward, the same group of polishing columns 29 is pushed away from the shaft column to be polished. When the liquid supply is stopped, the adjusting column arm 37 is retracted through the pull column spring 44, and the polishing column 29 is pulled close to the shaft column to be polished.

[0077] The above describes the embodiments of the present application, but the present application is not limited to the above specific embodiments. The above specific embodiments are only illustrative, but not limited. Those skilled in the art can make many forms under the inspiration of the embodiments, which are all within the protection scope of the embodiments.
