[0022] An embodiment of this application discloses an automatic loading and unloading mechanism for machining. Referring to Figures 1-5 , an automatic loading and unloading mechanism for machining includes a base 1. Two columns 3 are fixedly connected to the outer wall of the top of the base 1.

The feeding mechanism includes two synchronous pulleys 18 rotatably connected to the outer wall of the top of the base 1 through a mounting seat 17. A synchronous belt 19 is cooperatively installed on the outer walls of the two synchronous pulleys 18. The top outer wall of the synchronous belt 19 is fixedly connected to a processing table 16 through a connecting block 21. A stepping motor 20 is fixedly installed on the outer wall of one of the mounting seats 17. The end of the output shaft of the stepping motor 20 penetrates through the mounting seat 17 and is fixedly connected to the outer wall of the axis center of one of the synchronous pulleys 18.

[0023] Two guide rails 14 are fixedly connected to the outer wall of the top of the base 1. A slider 15 is slidably connected to the outer wall of the guide rail 14. Both sliders 15 are fixedly connected to the outer wall of the bottom of the processing table 16. The two synchronous pulleys 18 are located between the two guide rails 14, and the two synchronous pulleys 18 are distributed at both ends of the guide rail 14.

[0024] The lifting mechanism includes a worm gear 26 rotatably connected to the outer wall of the top of the fixing block 6 through a bearing. A worm 24 is rotatably connected to the outer wall of the top of the fixing block 6 through a shaft seat 23. The worm 24 meshes with the worm gear 26. A reduction motor 25 is fixedly installed on the outer wall of one of the shaft seats 23. The end of the output shaft of the reduction motor 25 penetrates through one of the shaft seats 23 and is fixedly connected to one end of the worm 24.

[0025] The outer wall of the lifting arm 7 is fixedly connected with a lead screw 22, and the lead screw 22 penetrates through the worm gear 26 and the fixed block 6, and the worm gear 26 is threadedly connected to the outer wall of the lead screw 22.

[0026] A blanking box 13 is arranged on the top outer wall of one side of the base 1 where the two guide rails 14 are located, and a material box 11 is fixedly connected to the top outer wall of the other side of the base 1 where the two guide rails 14 are located. Both the material box 11 and the blanking box 13 are parallel to the clamping jaw cylinder 10.

[0027] Avoidance grooves 12 are formed on the outer walls on both sides of the material box 11, and the clamping jaws of the clamping jaw cylinder 10 are adapted to the width of the avoidance grooves 12.

[0028] A plurality of through-type fixing holes 2 are formed on the top outer wall of the base 1, and the plurality of fixing holes 2 are uniformly distributed at the edge position of the base 1.

[0029] The implementation principle of an automatic loading and unloading mechanism for machining in an embodiment of the present application is as follows: During use, the base 1 can be fixed on the processing equipment through a plurality of fixing holes 2. Refer to Figure 1 , so that the left end of the base 1 corresponds to the processing area, and at this time, the loading operation can be carried out;

[0030] First, a plurality of materials are added into the material box 11, and then the linear motor 4 is started, so that the linear motor 4 drives the driving block 5 to slide, and the driving block 5 drives the fixed block 6 to move, so that the fixed block 6 moves close to the material box 11 until the fixed block 6 drives the lifting arm 7 and the clamping jaw cylinder 10 to be directly above the material box 11, and then the linear motor 4 stops;

[0031] Then, through the cooperation of the lifting mechanism, the reduction motor 25 is started, the output shaft of the reduction motor 25 drives the worm 24 to rotate, and the worm 24 drives the worm gear 26 meshed with it to rotate. The worm gear 26 rotates threadedly on the outer wall of the lead screw 22, and the worm gear 26 drives the lead screw 22 to move up and down, thereby driving the lifting arm 7 to move up and down inside the fixed block 6. When the lifting arm 7 descends, it drives the clamping jaw cylinder 10 to descend until the clamping jaw cylinder 10 contacts the topmost material in the material box 11, and then the clamping jaw cylinder 10 is started. The two clamping jaws of the clamping jaw cylinder 10 pass through the avoidance grooves 12 on both sides of the material box 11, which is convenient for clamping the material. It should be noted that the clamping jaw cylinder 10 is driven by the servo motor 8 to rotate, so that the clamping direction of the clamping jaw cylinder 10 can be adjusted, and the material can be adjusted in the horizontal direction by the clamping jaw cylinder 10;

[0032] After the material is clamped, the lifting mechanism drives the jaw cylinder 10 to rise, and the linear motor 4 drives the jaw cylinder 10 to move towards the processing table 16. When the material is above the processing table 16, the lifting mechanism drives the lifting arm 7 to descend, which drives the jaw cylinder 10 and the material to descend until the material is placed on the processing table 16. The jaw cylinder 10 releases the clamping of the material, and then the jaw cylinder 10 is driven by the lifting mechanism to rise and reset.

[0033] Then, through the feeding mechanism, the stepping motor 20 is started. The output shaft of the stepping motor 20 drives a synchronous pulley 18 to rotate, and the two synchronous pulleys 18 achieve synchronous rotation through the synchronous belt 19. During this process, the synchronous belt 19 drives the connecting block 21 to drive the processing table 16 to move, and the processing table 16 conveys the material to the processing area for processing, completing the feeding process.

[0034] When the material is processed on the processing table 16, the feeding mechanism drives the processing table 16 to reset. At this time, the lifting mechanism drives the lifting arm 7 to drive the jaw cylinder 10 to descend. The processed material is clamped by the jaw cylinder 10 and rises. Then, the linear motor 4 drives the jaw cylinder 10 and the material to move above the blanking box 13. The jaw cylinder 10 releases the clamping of the material, and the material falls into the blanking box 13 for collection, completing the blanking process.

[0035] By repeating this process, the automatic loading and unloading of materials can be realized, which can greatly reduce the manual operation links, reduce the risk of human error, improve the production efficiency and product quality, and is beneficial to the continuous and stable operation of the production line.
