[0031] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0032] According to one embodiment of the present invention, in conjunction with Figures 1-4 As shown. A square hole drill bushing grinding structure includes a mounting base 1, a lifting device body 2 fixed to the top of the mounting base 1, a grinding device body 3 fitted to the outside of the lifting device body 2, a grinding blade 4 fitted to the outside of the grinding device body 3, a metal seat 5 fixed to the top of the mounting base 1, a collecting housing 6 fixed to the top of the metal seat 5, a moving mechanism 7 fixed to the outside of the collecting housing 6, and a locking mechanism 8 provided on the top of the moving mechanism 7;

[0033] The moving mechanism 7 includes a fixed base 71, a servo motor 72 fixed to the outside of the fixed base 71, a gear 73 fixed to the outside of the output shaft of the servo motor 72, a rack 74 meshing with the top of the gear 73, a guide seat 75 fixed to the top of the rack 74, two fixed plates 76 fixed to the outside of the collecting housing 6, a guide rail 77 fixed between the corresponding surfaces of the two fixed plates 76, a connecting seat 78 mounted on the top of the guide seat 75, the fixed base 71 and the collecting housing 6 fixedly connected, the guide seat 75 movably sleeved on the outside of the guide rail 77, a locking mechanism 8 fixed to the top of the connecting seat 78, and the connecting seat 78 and the guide seat 75 bonded together, the guide seat 75 has a groove inside, the size of which matches the size of the rack 74, and a through groove inside, the size of which matches the size of the guide rail 77.

[0034] The locking mechanism 8 includes a fixing block 81, a motor fixing sleeve 82 fixed to the top of the fixing block 81, a motor mounting sleeve 83 rotatably connected to the top of the motor fixing sleeve 82 via a rotating shaft, and a stabilizing anti-slip sleeve 84 fixed to the inner walls of both the motor mounting sleeve 83 and the motor fixing sleeve 82. A lower cast iron block 85 is fixed to the outer side of the motor fixing sleeve 82, and a fixed semi-threaded column 87 is fixed to the outer side of the lower cast iron block 85. An upper cast iron block 86 is fixed to the outer side of the motor mounting sleeve 83, and a movable semi-threaded column 88 is fixed to the outer side of the upper cast iron block 86. A cast iron nut 89 is threadedly connected to the outer sides of the movable semi-threaded column 88 and the fixed semi-threaded column 87. The fixing block 81 and the connecting seat 78 are fixedly connected. A motor is clamped and fixed between the corresponding surfaces of the two stabilizing anti-slip sleeves 84. A square hole drill sleeve is installed on the outer side of the output shaft of the motor.

[0035] In this embodiment, by setting up a moving mechanism 7, after the servo motor 72 is started, the gear 73 drives the rack 74 to move back and forth. At this time, the rack 74 drives the guide seat 75 and the connecting seat 78 to move, allowing the guide seat 75 to move outside the guide rail 77. The guide rail 77 plays a guiding role for the guide seat 75, causing the locking mechanism 8 at the top of the connecting seat 78 to drive the motor and the square hole drill bushing to move linearly back and forth. Subsequently, the rotary motor fixed inside the locking mechanism 8 is started to drive the drill bushing to rotate, which can form a compound motion trajectory during the grinding process. This dynamic adjustment capability makes the grinding path more uniform and avoids the localization caused by traditional unidirectional feed. Excessive wear significantly shortens processing time. With the locking mechanism 8, when grinding the corresponding square hole drill sleeve, the square hole drill sleeve is installed on the outside of the corresponding motor, and the motor is placed on top of the motor fixing sleeve 82. Then, the motor mounting sleeve 83 is rotated so that the corresponding surface of the movable half-threaded column 88 fits against the fixed half-threaded column 87, and the stabilizing anti-slip sleeve 84 is tightly attached to the motor with the square hole drill sleeve fixed. Then, the cast iron nut 89 is threaded to the movable half-threaded column 88 and the fixed half-threaded column 87. The physical locking enhances the connection reliability after the motor is installed, ensuring the stability of the installation and the square hole drill sleeve grinding process. Moreover, the assembly process is simple.

[0036] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
