[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention facilitates the staff to select a suitable clamping tooling according to the processing requirements of the workpiece; when the output shaft of the linear electric cylinder extends, the movable clamping seat drives the clamping tooling below to move upward, realizing the automatic clamping of the workpiece to be processed; when the output shaft of the linear electric cylinder contracts, the movable clamping seat drives the clamping tooling below to move downward, facilitating the removal of the subsequent workpiece to be processed.

[0020] In addition, when the output shaft of the linear electric cylinder extends, the movable clamping seat drives two circular linkage rods to move upward, causing the two movable shielding plates to automatically rotate under the action of the two spiral linkage grooves and the two circular linkage rods, playing a shielding role to prevent cutting fluid from splashing on the protective door of the lathe during workpiece processing, making the lathe cleaner during use and reducing the subsequent cleaning difficulty; at the same time, when the protective door on the lathe is forgotten to be closed, the two movable shielding plates can also shield the processing waste chips, preventing the processed waste chips from accidentally injuring the staff; when the output shaft of the linear electric cylinder contracts, the movable clamping seat drives the two circular linkage rods to move downward, causing the two movable shielding plates to automatically reset under the action of the two spiral linkage grooves and the two circular linkage rods, facilitating the staff to remove the processed workpiece and also facilitating the placement of the workpiece to be processed.

[0021] 2. When the output shaft of the linear electric cylinder extends, the movable clamping seat drives two movable push frames to move upward, causing the two movable push frames to squeeze the four T-shaped movable frames to move outward simultaneously, ensuring that the bottoms of the four limit balls are in contact with the tops of the four mounting threaded nails, playing a limiting role on the four mounting threaded nails to ensure that the four mounting threaded nails will not loosen under force during workpiece processing; when the output shaft of the linear electric cylinder contracts, the movable clamping seat drives the two movable push frames to move downward, causing the four T-shaped movable frames to automatically reset under the action of the four spiral springs A, ensuring that when the lathe is not working, the four mounting threaded nails are in an exposed state, enabling the lathe connection frame to have the effect of being convenient for installation and disassembly when the lathe is not working.

[0022] In addition, when one or more of the mounting threaded nails are not properly installed, the limit balls cannot move to the tops of the corresponding mounting threaded nails, causing one or two of the spiral springs B on the corresponding side to be compressed when the output shaft of the linear electric cylinder extends; when one or two of the switches are pressed, the waterproof buzzer works, automatically prompting the staff to know that one or more of the mounting threaded nails are not properly installed, and also realizing the automatic detection of the positions of the four mounting threaded nails multiple times. Even when the four mounting threaded nails are slightly loosened for other reasons, the staff can also be informed in time, facilitating the timely tightening of the corresponding mounting threaded nails, which is beneficial to improving the machining accuracy of the workpiece.

[0023] 3. The provision of two workpiece storage housings in the present invention serves to temporarily place the processed workpieces, facilitating the centralized turnover of the processed workpieces by the staff, enabling the processed workpieces to be placed without moving a certain distance, and improving the processing efficiency of the workpieces; the provision of the hanging slots and the L-shaped hanging brackets facilitates the installation and disassembly of the workpiece storage mechanism.

[0024] In addition, when the output shaft of the linear electric cylinder is in the retracted state, the two movable shutter plates can push the two movable protection plates and the two circular push rods outward, facilitating the staff to place the processed workpieces in the workpiece storage housing; when the output shaft of the linear electric cylinder is in the extended state, the two movable protection plates can automatically reset under the action of the two spiral springs C, sealing the two workpiece storage housings and preventing cutting fluid or debris from entering the workpiece storage housings.

[0048] Its specific functions are as follows: Since four tooling connection holes are respectively formed in the lathe connection frame 101 and the movable clamping seat 102, it is convenient for the staff to select appropriate clamping tooling according to the processing requirements of the workpiece; because the clamping tooling on the lathe connection frame 101 and the movable clamping seat 102 will be replaced multiple times according to production requirements, the clamping tooling on the lathe connection frame 101 and the movable clamping seat 102 basically will not become loose, and the clamping tooling is locked every time it is replaced; and because the movable clamping seat 102 is slidably mounted on the lathe connection frame 101, the linear electric cylinder 104 is fixedly mounted on the lathe connection frame 101, and the output shaft of the linear electric cylinder 104 is fixedly connected to the movable clamping seat 102, when the output shaft of the linear electric cylinder 104 extends, the movable clamping seat 102 drives the clamping tooling below to move upward, realizing the automatic clamping of the workpiece to be processed; when the output shaft of the linear electric cylinder 104 contracts, the movable clamping seat 102 drives the clamping tooling below to move downward, facilitating the removal of the subsequent workpiece to be processed;

When the workpiece is being machined, cutting fluid splashing on the protective door of the lathe is avoided, making the lathe cleaner during use and reducing the subsequent cleaning difficulty. At the same time, when the protective door on the lathe is forgotten to be closed, the two movable shutter plates 403 can also shield the machining waste chips, preventing the waste chips after machining from accidentally injuring the staff. When the output shaft of the linear electric cylinder 104 contracts, the movable clamping seat 102 drives the two circular linkage rods 103 to move downward, causing the two movable shutter plates 403 to automatically reset under the action of the two spiral linkage grooves 4031 and the two circular linkage rods 103, facilitating the staff to remove the machined workpiece and also facilitating the placement of the workpiece to be machined.

After that, according to the processing requirements of the workpiece, a suitable clamping tooling is selected and installed on the lathe connection frame 101 and the movable clamping seat 102 by screws; when the output shaft of the linear electric cylinder 104 extends, the movable clamping seat 102 drives the clamping tooling below to move upward, realizing the automatic clamping of the workpiece to be processed; when the output shaft of the linear electric cylinder 104 contracts, the movable clamping seat 102 drives the clamping tooling below to move downward, facilitating the removal of the subsequent workpiece to be processed; when the output shaft of the linear electric cylinder 104 extends, the movable clamping seat 102 drives the two circular linkage rods 103 to move upward, causing the two movable shielding plates 403 to automatically rotate under the action of the two spiral linkage grooves 4031 and the two circular linkage rods 103, playing a shielding role to prevent cutting fluid from splashing on the protective door of the lathe during workpiece processing, making the lathe cleaner during use and reducing the subsequent cleaning difficulty; at the same time, when the protective door on the lathe is forgotten to be closed, the two movable shielding plates 403 can also shield the processing waste chips to prevent the processed waste chips from accidentally injuring the operator; when the output shaft of the linear electric cylinder 104 contracts, the movable clamping seat 102 drives the two circular linkage rods 103 to move downward, causing the two movable shielding plates 403 to automatically reset under the action of the two spiral linkage grooves 4031 and the two circular linkage rods 103, facilitating the operator to remove the processed workpiece and also facilitating the placement of the workpiece to be processed; when the output shaft of the linear electric cylinder 104 extends, the movable clamping seat 102 drives the two movable push frames 303 to move upward, causing the two movable push frames 303 to squeeze the four T-shaped movable frames 202 to move outward simultaneously, ensuring that the bottoms of the four limit balls 203 contact the tops of the four mounting threaded nails 105, playing a limiting role on the four mounting threaded nails 105 to ensure that the four mounting threaded nails 105 will not loosen under force during workpiece processing; when the output shaft of the linear electric cylinder 104 contracts, the movable clamping seat 102 drives the two movable push frames 303 to move downward, causing the four T-shaped movable frames 202 to automatically reset under the action of the four spiral springs A204, ensuring that when the lathe is not working, the four mounting threaded nails 105 are exposed, enabling the lathe connection frame 101 to have the effect of being convenient for installation and disassembly when the lathe is not working; when one or more of the mounting threaded nails 105 are not properly installed, the limit ball 203 cannot move to the top of the corresponding mounting threaded nail 105, causing one or two of the spiral springs B306 on the corresponding side to be compressed when the output shaft of the linear electric cylinder 104 extends;When one or both of the switches 307 are pressed, the waterproof buzzer 302 works, which can automatically prompt the staff to know that one or more of the installation threaded nails 105 are not properly installed. It also realizes the automatic detection of the positions of the four installation threaded nails 105 multiple times. Even when the four installation threaded nails 105 are slightly loosened for other reasons, the staff can also know in time, which is convenient for tightening the corresponding installation threaded nails 105 in time, and is beneficial to improving the processing precision of the workpiece. The setting of the two workpiece storage shells 502 plays a role in temporarily placing the processed workpieces, which is convenient for the staff to centrally transfer the processed workpieces, so that the processed workpieces do not need to be placed after moving a certain distance, improving the processing efficiency of the workpieces. The setting of the hanging slot holes 5011 and the L-shaped hanging brackets 106 facilitates the installation and disassembly of the workpiece storage mechanism 500. When the output shaft of the linear electric cylinder 104 is in the retracted state, the two movable shutter plates 403 can push the two movable protection plates 504 and the two circular push rods 505 to move outward, facilitating the staff to place the processed workpiece in the workpiece storage shell 502. When the output shaft of the linear electric cylinder 104 is in the extended state, the two movable protection plates 504 can automatically reset under the action of the two spiral springs C507, playing a sealing role for the two workpiece storage shells 502 and preventing cutting fluid or debris from entering the workpiece storage shells 502.;
