[0029] Please refer to Figures 1 - 5 , the automatic loading and unloading mechanism of a six-axis grinding machine, including a six-axis grinding machine body 1. Grinding vertical plates 11 for accommodating tool processing operations are symmetrically installed on the top surface of the six-axis grinding machine body 1. Above the six-axis grinding machine body 1, a driving and adjusting structure 3, a lifting structure 4, and a driving and clamping structure 5 are successively arranged from top to bottom. The driving and adjusting structure 3 includes a mounting plate 31. A longitudinal threaded rod 33 and a sliding rod 34 are rotatably connected to the bottom of the mounting plate 31. Sliding blocks 35 are slidably connected to the outer walls of the longitudinal threaded rod 33 and the sliding rod 34.

Rotating rods 52 are symmetrically installed on the side wall of the L-shaped plate 51. A forward and reverse motor 55 is coaxially connected to the outer wall of one of the rotating rods 52. A number of clamping assemblies 54 arranged at equal intervals are installed on the outer walls of the two rotating rods 52. A control panel is installed on the top surface of the mounting plate 31. A PLC controller is arranged inside the control panel. The PLC controller is electrically connected to the first servo motor 32, the second servo motor 38, the electric telescopic rod 43, and the forward and reverse motor 53 through wires. By driving the longitudinal threaded rod 33 and the transverse threaded rod 37 to rotate respectively through the first servo motor 32 and the second servo motor 38, the positions of the sliding blocks 35 and the threaded sleeve 41 are adjusted, and the driving and clamping structure 5 is driven to lift through the electric telescopic rod 43, so that the clamping block 544 can calibrate its own position and clamp the tool on the grinding vertical plate 11, which not only avoids the phenomenon of the clamping block 544 offsetting, but also can improve the loading and unloading rate and save labor.

[0030] In this embodiment, the clamping assembly 54 includes a rotating block 541 rotatably connected to the rotating rod 52. A half gear 542 is fixedly connected to the outer wall of the rotating block 541, and the two half gears 542 are meshed with each other, facilitating the adjustment of the distance between the two oppositely arranged clamping blocks 544.

[0031] Then, both outer walls on both sides of the bottom end of the rotating block 541 are hinged with adjusting blocks 543, and the same clamping block 544 is hinged to one end of the two adjusting blocks 543 away from the rotating block 541, facilitating the normal use of the structure.

[0033] It is worth noting that mounting grooves 310 for accommodating the sliding of the sliding block 35 are symmetrically formed on the bottom surface of the mounting plate 31. One end of the longitudinal threaded rod 33 penetrates through the outer wall of the mounting plate 31 and is coaxially key-connected to a first servo motor 32, facilitating the driving of the longitudinal threaded rod 33 to rotate.

[0034] Next, the lower end of the sliding block 35 is threadedly connected to the longitudinal threaded rod 33, and the first servo motor 32 is fixed to the outer wall of the mounting plate 31 by bolts, facilitating the normal use of the structure.

[0036] Furthermore, a mounting block 42 is welded and fixed to the bottom end of the threaded sleeve 41, and the top end of the electric telescopic rod 43 is fixed to the bottom surface of the mounting block 42 by screws, facilitating the normal use of the structure.

[0037] Finally, it should be noted that components such as the first servo motor 32, the second servo motor 38, the electric telescopic rod 43, the forward and reverse motor 53, and the PLC controller in the present utility model are all general standard components or components known to those skilled in the art.

The specific connection means should refer to the working principle in the present utility model, and the electrical components are electrically connected in accordance with the sequential working order. Their detailed connection means are all well-known technologies in the art.

[0038] Working principle: When using the automatic loading and unloading structure of this six-axis grinding machine, the user first turns on the first servo motor 32, the second servo motor 38, and the electric telescopic rod 43 through the PLC controller in the control panel on the top surface of the mounting plate 31, so that several groups of symmetrically arranged clamping blocks 544 calibrate their positions above the processing tools on the two grinding vertical plates 11. Then, turn on the forward and reverse motor 53, adjust the distance between several groups of symmetrically arranged clamping blocks 544 in pairs and clamp the processing tools, and then pick up and place the processing tools.
