[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0017] Example: Figure 1 - Figure 6 As shown, this embodiment proposes a multi-station quick-assembly type small CNC drilling and milling machine worktable structure, including: a worktable base 1, a workpiece mounting seat 2 slidably connected to the top of the worktable base 1, the workpiece mounting seats 2 are arranged in several groups and distributed along the length direction of the worktable base 1, a positioning component 3 is provided on one side of the workpiece mounting seat 2 for positioning the workpiece mounting seat 2 in a suitable position on the worktable base 1, and a quick-assembly component 4 is provided on the workpiece mounting seat 2 for quickly locking and fixing the workpiece mounting seat 2 on the worktable base 1. like Figure 3 and Figure 5As shown, the positioning component 3 includes a positioning block 301 fixedly installed on the side wall of the workpiece mounting base 2. The positioning block 301 has a receiving groove 302 inside, and a positioning pin 303 is inserted into the receiving groove 302. The side wall of the worktable base 1 has a positioning groove 304. The end of the positioning pin 303 passes through the receiving groove 302 and is embedded in the positioning groove 304. A spring 305 is sleeved on the outer side wall of the positioning pin 303. In use, the worktable base 1 is mounted on the bed of a small CNC drilling and milling machine. A lead screw is fixedly mounted on the bed of the small CNC drilling and milling machine. The CNC system of the small CNC drilling and milling machine controls the worktable base 1 to move back and forth horizontally for successive drilling and milling of the workpiece placed on the worktable base 1. According to the processing requirements of the workpiece, the user pulls the positioning pin 303 outward and pushes the workpiece mounting seat 2 along the direction of the T-slot. At this time, the spring 305 is compressed, sliding the workpiece mounting seat 2 to the predetermined processing position on the worktable base 1. When the workpiece mounting seat 2 moves into place, the positioning pin 303 is released, and the spring 305 is compressed. 5. Quickly reset and extend, the spring 305 drives the positioning pin 303 to move towards the side wall of the worktable base 1, so that the end of the positioning pin 303 is embedded in the positioning groove 304 at the corresponding position, and the workpiece mounting seat 2 is positioned in a suitable position on the worktable base 1; positioning grooves 304 with different spacings can be opened on the side wall of the worktable base 1. When it is necessary to adjust the position of the workpiece mounting seat 2, simply align the positioning pin 303 with the positioning groove 304 of the required spacing and insert it. The operator can flexibly select positioning grooves 304 with different spacings for positioning according to actual processing needs, so as to adapt to the processing requirements of workpieces of different sizes.

[0018] like Figure 3 and Figure 6 As shown, the quick-assembly assembly 4 includes a T-shaped groove 401 opened on the top of the workbench base 1, and a connecting plate 402 symmetrically bolted to the side wall of the workpiece mounting seat 2. A limiting groove 403 is opened on the connecting plate 402, and a locking pin 404 is inserted into the limiting groove 403. A T-shaped block 405 is fixedly provided at the bottom of the locking pin 404. In use, after the workpiece mounting seat 2 is fixed in a suitable position on the worktable base 1, the locking pin 404 is passed through the limiting groove 403 on the connecting plate 402 from top to bottom. The T-block 405 is placed into the T-slot 401, so that the bottom surface of the T-block 405 abuts against the bottom of the T-slot 401. At the same time, the rod of the locking pin 404 passes through the limiting groove 403 and extends upward. Then, the locking pin 404 is rotated ninety degrees, so that the connecting plate 402 is pressed and fixed on the upper surface of the worktable base 1, thereby locking the workpiece mounting seat 2 as a whole onto the worktable base 1, which facilitates drilling and milling operations on the workpiece.

[0019] like Figure 5As shown, an anti-detachment piece 5 is fixedly installed on the outer wall of the positioning pin 303, and the anti-detachment piece 5 is located in the receiving groove 302. In use, the positioning pin 303 drives the anti-detachment piece 5 to move synchronously in the receiving groove 302. During the entire sliding process of the positioning pin 303, the anti-detachment piece 5 is always located in the receiving groove 302. When the positioning pin 303 moves outward to its maximum stroke, the anti-detachment piece 5 abuts against the outer wall of the receiving groove 302, restricting the positioning pin 303 from continuing to detach outward, thereby preventing the positioning pin 303 from being accidentally pulled completely out of the receiving groove 302 during operation.

[0020] like Figure 5 As shown, one end of the spring 305 is fixedly connected to the side wall of the anti-detachment piece 5, and the other end of the spring 305 is fixedly connected to the inner side wall of the receiving groove 302. In use, both ends of the spring 305 are fixedly connected to the anti-detachment piece 5 and the inner side wall of the receiving groove 302, respectively. The movement trajectory of the spring 305 in the receiving groove 302 is constrained by the anti-detachment piece 5 and the inner wall of the receiving groove 302, preventing radial deviation or twisting and ensuring the smoothness of the extension and retraction process of the spring 305.

[0021] like Figure 2 and Figure 5 As shown, an anti-slip handle 6 is fixedly installed at the end of the positioning pin 303, and the anti-slip handle 6 is located on the outside of the positioning block 301. In use, the user holds the anti-slip handle 6 and pulls it outward according to the processing requirements of the workpiece. The anti-slip handle 6 drives the positioning pin 303 to move outward synchronously, releasing the axial limit on the workpiece mounting seat 2. Then, the user pushes the workpiece mounting seat 2 along the direction of the T-slot 401, so that the workpiece mounting seat 2 slides to the predetermined processing position on the worktable base 1 for easy use.

[0022] like Figure 6 As shown, a locking nut 7 is rotatably connected to the top of the locking pin 404, and the locking nut 7 is located on one side of the connecting plate 402. In use, hold the locking nut 7 and rotate it so that the bottom surface of the locking nut 7 tightly abuts against the upper surface of the connecting plate 402. The locking nut 7 applies a downward clamping force to the connecting plate 402, pressing and fixing the connecting plate 402 to the upper surface of the workbench base 1, thereby locking and fixing the workpiece mounting seat 2 as a whole onto the workbench base 1.

[0023] like Figure 2 and Figure 4 As shown, a slider 8 is fixedly connected to the bottom of the workpiece mounting base 2, and the slider 8 is embedded in the T-groove 401. In use, the workpiece mounting base 2 can slide within the T-groove 401 by means of the slider 8, and the slider 8 can only slide freely along the length direction of the T-groove 401, so the position of the workpiece mounting base 2 can be adjusted.

[0024] Working Principle: This utility model provides a multi-station quick-assembly small CNC drilling and milling machine worktable structure. In use: the worktable base 1 is mounted on the bed of the small CNC drilling and milling machine. The CNC system of the small CNC drilling and milling machine controls the worktable base 1 to move horizontally back and forth. For successive drilling and milling of the workpiece placed on the worktable base 1, the user pulls the positioning pin 303 outward and pushes the workpiece mounting seat 2 along the T-slot direction. At this time, the spring 305 is compressed, sliding the workpiece mounting seat 2 to the predetermined machining position on the worktable base 1. When the workpiece mounting seat 2 moves into place, the positioning pin 303 is released, and the spring 305 quickly returns to its original position and extends. The spring 305 drives the positioning pin 303 to move towards the worktable base 1. The side wall of the worktable base 1 moves in a certain direction, so that the end of the positioning pin 303 is embedded in the positioning groove 304 at the corresponding position, and the workpiece mounting seat 2 is positioned in a suitable position on the worktable base 1. The locking pin 404 passes through the limiting groove 403 on the connecting plate 402 from top to bottom, and the T-block 405 is placed in the T-groove 401 so that the bottom surface of the T-block 405 abuts against the bottom of the T-groove 401. At the same time, the rod of the locking pin 404 passes through the limiting groove 403 and extends upward. Then, the locking pin 404 is rotated ninety degrees so that the connecting plate 402 is pressed and fixed on the upper surface of the worktable base 1, thereby locking and fixing the workpiece mounting seat 2 as a whole on the worktable base 1, which facilitates drilling and milling operations on the workpiece.

[0025] All technical features in this embodiment can be freely combined according to actual needs.

[0026] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
