[0026] The buffer assembly 40 includes a first plate body 41, a groove 411, a support plate 42, a roller 43, a connecting rod 44, a fixed column 45, a spring 46, a connecting plate 47, a sliding rod 48 and a second plate body 49. Equidistantly arranged grooves 411 are provided on both sides of the top of the first plate body 41. A connecting rod 44 is provided inside the groove 411. One end of the connecting rod 44 is rotatably connected to the roller 43. Two fixed columns 45 are welded to both ends of the connecting rod 44. Connecting plates 47 are welded to both ends of the spring 46. The two fixed columns 45 are welded to the upper surface of the connecting plate 47 at the top of the spring 46.

[0027] In this embodiment, specifically: the main body component 10 includes a main machine 11, a first base 12 and a clamping component 20, the main machine 11 is installed on one side of the first base 12, two transmission components 30 are provided, and the two transmission components 30 are respectively installed on both sides of the first base 12, and the two transmission components 30 can realize loading or unloading operations, which can greatly improve the processing efficiency of the machine tool.

[0028] In this embodiment, specifically: the clamping assembly 20 includes a second base 21, a first workbench 22, a fixture 23, a workpiece 24, a first cylinder 25 and a slot 26. The top of the first workbench 22 is screwed to the second base 21, and three fixtures 23 are fixedly connected to the top of the second base 21. The internal screws of the fixture 23 are connected to the first cylinder 25. The top of the first cylinder 25 is connected to the workpiece 24 through a locating pin. The bottom of the first workbench 22 is provided with a slot 26. The three locating pins are lifted onto the workpiece 24 respectively by the first cylinders 25 in the three fixtures 23 to calibrate and position the workpiece 24.

[0029] In this embodiment, specifically: a side of the fixed platform 34 away from the first base 12 is screwed to a motor 31, sprockets 371 are provided on both sides of the inside of the fixed platform 34, the two sprockets 371 are connected by a transmission chain 37, and the output end of the motor 31 is fixedly connected to the sprocket 371. Through the cooperation of the motor 31 and the sprocket 371, the transmission chain 37 is rotated to drive the mechanical arm 35 on the second cylinder 38 to operate in the linear guide 32.

[0030] In this embodiment, specifically: fixed plates 36 are welded on both sides of the top of the second workbench 39, support plates 42 are welded on both sides of the bottom of the first plate body 41, one side of the support plate 42 is welded to the top of the second workbench 39, and the opposite sides of the two fixed plates 36 are rotatably connected with equidistantly arranged transmission wheels 33, and the support plates 42 are used to support the first plate body 41. When the robotic arm 35 pulls the first workbench 22, the first workbench 22 slides on the transmission wheel 33 to facilitate dragging the first workbench 22.

[0031] In this embodiment, specifically: the inner bottom wall of the groove 411 is fixedly connected to the second plate body 49, and sliding rods 48 are welded to the top two sides of the second plate body 49. The ends of the two sliding rods 48 away from the second plate body 49 pass through the interior of the connecting plate 47, and the sliding rods 48 are slidably connected to the connecting plate 47. When the fixed column 45 squeezes the spring 46 through the upper connecting plate 47, the lower connecting plate 47 slides on the sliding rod 48, thereby improving the stability of the connecting plate 47 and the spring 46.

[0032] The working principle or structural principle is that when in use, the motor 31 rotates forward to make the sprocket 371 drive the transmission chain 37 to rotate, so that the mechanical arm 35 extends to the corresponding position on the lower side of the first workbench 22, and the second cylinder 38 rises after ventilation, and hooks the first workbench 22 through the hook of the mechanical arm 35. The motor 31 is reversed to make the sprocket 371 drive the transmission chain 37 to rotate, and the first workbench 22 hooked by the hook of the mechanical arm 35 is dragged to the unloaded workbench and the unloading area through the transmission wheel 33. After completion, the next first workbench 22 is placed in the working area of ​​the second workbench 39 to continue processing. When the arm 35 drags the first workbench 22 through the transmission wheel 33, the first workbench 22 slides on the roller 43 on the first plate 41, thereby improving the stability of the first workbench 22 during dragging. In the area where the first workbench 22 is subjected to greater force, the roller 43 presses the fixed column 45 downward through the two ends of the connecting rod 44, and the fixed column 45 squeezes the spring 46 through two connecting plates 47 for buffering, and makes the connecting plate 47 at the lower part of the spring 46 slide on the sliding rod 48 until the connecting plate 47 contacts the second plate 49, thereby fixing the roller 43 and further improving the stability of the first workbench 22.
