[0020] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0021] like Figure 1-Figure 4 As shown, a loading and unloading device of a double-station CNC machine tool comprises a processing table 1, a machine tool side plate 2, a first grabbing member and a second grabbing member, two processing positions 3 are arranged on the processing table 1, a through groove 4 is opened on the side wall of the machine tool side plate 2, a hydraulic cylinder 5 is fixedly installed at the center of the bottom surface of the through groove 4, a rotating cylinder 28 is fixedly installed on the output end of the hydraulic cylinder 5, a connecting plate 6 is fixedly connected to the top of the rotating cylinder 28, two multi-stage push rods 7 are fixedly connected to the side wall of the connecting plate 6 symmetrically, an adjusting plate 8 is fixed on the output end of the multi-stage push rod 7, an electric push rod 9 is installed on the top surface of the adjusting plate 8, the output end of the electric push rod 9 passes through the adjusting plate 8 and is fixedly connected to a sleeve 10, two arc grooves 12 are opened on the side wall of the sleeve 10, the first grabbing member and the second grabbing member are both adapted to the sleeve 10, and a finished product station 22 and a blank station 23 are arranged on the outer side of the machine tool side plate 2.

[0022] The adjusting plate 8 is L-shaped, and two reinforcing ribs 29 are fixedly connected to the transition part of the adjusting plate 8. The reinforcing ribs 29 can enhance the supporting strength of the adjusting plate 8 to avoid deformation caused by the gravity of the workpiece.

[0023] Secondly, an adjustment groove is opened on the top surface of the adjustment plate 8, and the electric push rod 9 is located in the adjustment groove. The electric push rod 9 can be adjusted in other forms such as nuts and locks to make it suitable for workpieces of different sizes and spacings.

[0024] like Figure 1 and Figure 2 As shown, the first grasping member includes a first round rod 11, which is adapted to the sleeve 10, and two support rods 13 are symmetrically fixedly connected to the side wall of the first round rod 11, and the support rods 13 correspond to the arc groove 12, and a mounting plate 14 is fixedly connected to the bottom end of the first round rod 11, and suction cups 16 are installed on the bottom surface of the mounting plate 14 near the four corners.

[0025] The model and specification of the suction cup 16 are not specifically limited here. Due to the different workpieces to be processed, different suction cups 16 can be adjusted according to the specifications of the workpieces.

[0026] Long holes 15 are provided near the corners of the top surface of the mounting plate 14 , and suction cups 16 are located in the long holes 15 . The side walls of the suction cups 16 are located at the upper and lower sides of the mounting plate 14 and are threadedly connected with nuts 17 .

[0027] Specifically, the long holes 15 can be used to adjust the distance between the suction cups 16 according to the size of the workpiece, so as to provide a stronger adsorption force; and the suction cups 16 can only absorb workpieces with a flat surface and light weight.

[0028] like Figure 3 As shown, the second gripping member includes a second round rod 18, which is adapted to the sleeve 10, and two cross bars 19 are symmetrically fixedly connected to the side wall of the second round rod 18, and an adapter plate 20 is installed at the bottom end of the second round rod 18, and a pneumatic clamp 21 is installed on the bottom surface of the adapter plate 20.

[0029] Specifically, the pneumatic clamp 21 is mainly used for cylinders, rectangles, irregular bodies and smaller workpieces; the pneumatic clamp 21 is not installed under the adapter plate 20 in this solution, but the installation structure is not strictly limited to the first gripping member and the second gripping member in this solution, and can be selected according to actual needs.

[0031] Specifically, the bottom of the folding curtain 26 can be designed to be downwardly folded, so that the bottom length thereof hangs below the through groove 4, so that after being closed, the cutting fluid splashed during processing will not leak out through the through groove 4, thereby ensuring a dry and clean processing environment.

[0032] The working principle of the utility model is as follows: when the machine tool has finished processing the workpiece on the processing position 3, the sliders 25 on both sides drive the folding curtains 26 to open. At this time, the operating rotary cylinder 28 first drives the outer clamp to move to the blank station 23, and drives the clamp to clamp the two blanks through the electric push rod 9, then the rotary cylinder 28 is reset, and at the same time the hydraulic cylinder 5 drives the whole to rise, the multi-stage push rod 7 inside the machine tool drives the clamp to extend above the finished workpiece, and then the electric push rod 9 is started to drive the clamp to move downward to clamp the finished workpiece, and then the multi-stage push rod 7 is reset, the rotary cylinder 28 rotates 150-180°, and after the finished workpiece is placed on the finished workpiece station 22, the blank is placed on the processing position 3, and then the rotary cylinder 28 and the multi-stage push rod 7 are reset, and the slider 25 drives the folding curtain 26 to close the through slot 4, and a new round of processing begins.

[0033] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
