There is a cylinder connected with a pneumatic device on top of the lifting body, which is the horizontal driving device mentioned, and the outer end of the piston rod matched with the cylinder is connected with the linear guide mentioned. The cylinder is installed vertically above the bed and the hydraulic control device is connected to each other, this cylinder is the lifting and lowering drive mechanism, and the cylinder is matched with the piston rod outside the end of the lifting and lifting body is connected to each other.

There are two linear guides as described, and the two are set in a parallel state. At one end of the linear guide, there is a connecting plate. The end of the piston rod, which is to be connected to the cylinder, is connected to the linear guide with the help of this connecting plate.

The invention has automatic loading and unloading mechanism for bar material, when the workpiece on the processing position is processed, the bar material on the position to be processed is in the waiting condition, the first bracket is in the position below the bar material to be processed, and the second bracket is in the position below the processing position, after the processing is completed, the oil cylinder generates the action and drives the lifting body to rise, at the same time, the air cylinder, the slider, the linear guideway, the first bracket and the second bracket rise together, at this time, the vertical rod moves upward relative to the guiding sleeve and plays the role of guiding. At the same time, the cylinder, slider, linear guide, first block and second block go upward, at this time, the vertical bar moves upward with respect to the guiding sleeve and plays the role of guiding. The processed bar is detached from the processing position and placed on the second pallet, at the same time, the bar to be processed is placed on the first pallet, and then, the action of the cylinder drives the linear guide to the right relative to the slider in the horizontal direction, so that the first pallet to be processed bar into the processing position, the second pallet to be processed bar into the lower material workstation to achieve the next material, and then the cylinder returns to the original position, and then the cylinder also returns to the original position. The cylinder then returns to its original position, followed by the air cylinder, arriving at the initial position to carry out the next cycle. This automatic loading and unloading mechanism is simple in structure, convenient in operation, easy in control, safe in loading and unloading, which saves time and effort and improves the working efficiency.

[Specific implementation modalities]

As shown in Figure 1, I is a bed of a machine tool, on which a guiding sleeve 3 is fixed vertically, in which a rod 5 is provided by means of linear bearings 4, and which is capable of axial movement. The lower part of the guiding sleeve 3 is fixed by means of fixing bolts 2, which are six in number and evenly distributed along the circumference. The lower part of the guide sleeve is connected to the lower cover 15 by means of screws, and the upper part of the guide sleeve 3 is bolted to the upper cover 12 of the guide sleeve. 6 is fixedly connected to the upper part of the riser 5, and the lower part of the riser 6 is bolted to the bottom cover 11, which is also shown in FIG. 2. Above the lifting body 6, two rows of sliders 17 are fixed, two in each row, with which two linear guide rails 9 are set up in parallel, the linear guide rails 9 are connected to a horizontal driving device, the horizontal driving device is installed on the lifting body 6 with a pneumatic device connected to the cylinder 13, and the piston rod 7 matched to the cylinder 13 is connected to the connecting plate 8 at its outer end, and each of the linear guide rails 9 is connected to the connecting plate 8, and the connecting plate 8 moves with the piston rod 7 as the connecting plate 8 moves with the connecting plate 8. When the connecting plate 8 moves with the piston rod 7, it can drive each linear guide 9 to move. Above the linear guide rails 9, parallel first and second brackets 10 and 14 are fixed for supporting the bar material.
