The lifting mechanism 7 and the four sides of the rectangular frame 6 are equipped with clamping components 5. The workpiece to be processed is placed on the placement table 8, and the workpiece is positioned and fixed by the clamping components 5 in four directions. After completion, it can be processed. Since there are two rectangular frames 6, one can be processed while the other is unloading or loading, ensuring continuous processing. The reciprocating translation mechanism can push the first slider 10 to move, and the first slider 10 drives the moving table 9 to move synchronously, so that one rectangular frame 6 can be placed at the processing position and the other rectangular frame 6 can be placed at the loading and unloading position. After processing is completed, the clamping components 5 are removed, and the placement table 8 can be lifted by the lifting mechanism 7 for easy handling.

[0019] Reference Figure 1 The reciprocating translation mechanism includes a first motor 11 and a first lead screw 12. The first motor 11 is mounted on the support base 2. The output shaft of the first motor 11 is connected to the first lead screw 12. The first lead screw 12 is threadedly sleeved inside the first slider 10. The first motor 11 drives the first lead screw 11 to rotate. The first lead screw 11 can push the first slider 10 to translate through the threaded transmission between it and the first slider 10. The reciprocating movement of the first slider 10 is realized by the forward and reverse rotation of the first motor 11.

[0020] Reference Figure 2 The bottom of the moving table 9 is fixed with several second mounting seats 16. The second mounting seats 16 are located in the first strip hole 4. Rollers 17 are installed on the side of the second mounting seats 16. A rolling groove 3 is opened on the inner wall of the worktable 1. The rollers 17 are rolled in the rolling groove 3. By the rollers 17 rolling in the rolling groove 3, the stability of the moving table 9 can be improved.

[0021] Reference Figure 2The lifting mechanism 7 comprises a second motor 71, a second screw rod 72, a second sliding block 73 and a support rod 74. The second motor 71 is installed at one end of the moving table 9. The output shaft of the second motor 71 is inserted into the interior of the moving table 9 and is connected with the second screw rod 72. The second screw rod 72 is sleeved with two second sliding blocks 73 through threads with opposite rotation directions. The support rod 74 is hingedly connected between the second sliding blocks 73 and the placing table 8. The interior of the moving table 9 is provided with a cavity. The lifting mechanism 7 is located in the cavity. The top of the moving table 9 is provided with a third slot. The support rod 74 is located in the third slot. The second motor 71 drives the second screw rod 72 to rotate. The second screw rod 72 drives the two second sliding blocks 73 to move towards or away from each other through the threaded transmission between the second sliding blocks 73. Therefore, the moving table 9 can be lifted or lowered through the two support rods 74.

[0022] With reference to Figure 2 The clamping assembly 5 comprises a hydraulic cylinder 51 and a pressing plate 52. The hydraulic cylinder 51 is installed on the rectangular frame 6. The piston rod of the hydraulic cylinder 51 penetrates through the rectangular frame 6 and is fixed with the pressing plate 52. The hydraulic cylinder 51 drives the pressing plate 52 to move. The pressing plate 52 abuts against the side edge of the workpiece. The workpiece can be positioned and fixed through the four pressing plates 52.

[0023] With reference to Figure 1 The bottom of the workbench 1 is fixed with two first mounting seats 14. The first mounting seat 14 is installed with a travel switch 15.

[0024] Working principle: when in use, the workpiece to be machined is placed on the placing table 8. The workpiece is positioned and fixed through the four clamping assemblies 5. After completion, the workpiece can be machined. Since the rectangular frame 6 is provided with two, one can be machined while the other is unloaded or loaded, so as to ensure the continuous machining. The first sliding block 10 can be driven to move through the reciprocating translation mechanism. The moving table 9 is synchronously moved through the first sliding block 10, so that one of the rectangular frames 6 is located at the machining position, and the other rectangular frame 6 is located at the loading and unloading position. After the machining is completed, the clamping assembly 5 is removed. The placing table 8 can be lifted through the lifting mechanism 7, so as to facilitate taking and placing. The moving stability of the moving table 9 can be improved through the rolling of the rollers 17 in the rolling grooves 3.

[0025] The action principle of the reciprocating translation mechanism is that the first motor 11 drives the first screw rod 11 to rotate. The first screw rod 11 drives the first sliding block 10 to translate through the threaded transmission between the first sliding block 10. The first motor 11 is reversely rotated, so as to realize the reciprocating movement of the first sliding block 10.

[0026] The action principle of the lifting mechanism 7 is that the second motor 71 drives the second screw rod 72 to rotate, the second screw rod 72 drives the two second sliding blocks 73 to move towards or away from each other through the threaded transmission between the second sliding blocks 73, and then the moving table 9 is driven to ascend or descend through the two supporting rods 74.

[0027] The action principle of the clamping assembly 5 is that the hydraulic cylinder 51 drives the pressing plate 52 to move, the pressing plate 52 abuts against the side edge of the workpiece, and the workpiece is positioned and fixed through the four pressing plates 52.
