[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses a precision engraving machine capable of rapid positioning, referring to... Figure 1-4 The system includes a worktable 1, with a rotating groove on the upper side of the worktable 1. A fixed frame 4 is rotatably mounted inside the rotating groove via a rotating shaft 3. Electric push rods 5 are symmetrically mounted at both ends of the fixed frame 4. A clamping seat 6 is fixedly mounted at the output end of the two electric push rods 5 on the same side. A threaded rod 61 is threadedly connected to the clamping seat 6. The end of the threaded rod 61 extends into the interior of the clamping seat 6 and is rotatably connected to a clamping plate 62. A drive assembly 2 for driving the rotating shaft 3 is mounted on the side wall of the worktable 1. The drive assembly 2 includes a drive motor 21 fixedly mounted on the side wall of the worktable 1. A worm gear 22 is fixedly connected to the output shaft of the drive motor 21. A worm wheel 23 is meshed on the upper side of the worm gear 22. The worm wheel 23 is fixedly sleeved on the outer side of the rotating shaft 3. A support frame 8 is slidably mounted on the top of the worktable 1, and an engraving head 9 is slidably mounted on the bottom of the support frame 8.

[0023] Here, the workpiece to be engraved is placed inside the clamping seat 6, and then the electric push rod 5 is activated according to the size of the workpiece. The electric push rod 5 can push the clamping seat 6 closer to the workpiece. In conjunction with the rotation of the threaded rod 61, the threaded rod 61 can push the clamping plate 62 downward to achieve fixed clamping of the workpiece. Then, the engraving head 9 is activated to perform the engraving operation on the workpiece. Secondly, the device can activate the drive motor 21, which can drive the worm gear 22 to rotate. The worm gear 22 meshes with the worm wheel 23 to drive the rotating shaft 3 and the fixed frame 4 to rotate, so that the workpiece can be rotated to adjust the engraving angle of the workpiece. When the fixed frame 4 rotates 180 degrees, the workpiece can be flipped over for engraving, which improves the practicality of the device.

[0024] Reference Figure 1 Two electric slide rails 7 are symmetrically installed on the top of the workbench 1. Each of the two electric slide rails 7 has a slide rail seat 71 that is slidably mounted on it. The support frame 8 is fixedly installed on the top of the two slide rail seats 71.

[0025] Here, by activating the electric slide rail 7, the electric slide rail 7 can push the support frame 8 to move laterally, and the support frame 8 drives the engraving head 9 to move synchronously, thereby realizing the lateral position adjustment of the engraving head 9.

[0026] Reference Figure 4 The support frame 8 has a movable groove 81 on its top inner wall. A movable screw 82 is rotatably installed inside the movable groove 81. A movable seat 83 is threadedly connected to the outer side of the movable screw 82. The engraving head 9 is fixedly installed at the bottom of the movable seat 83. A movable motor 84 for driving the movable screw 82 to rotate is fixedly installed on the side wall of the support frame 8.

[0027] Here, by starting the moving motor 84, the moving motor 84 can drive the moving lead screw 82 to rotate, and the moving lead screw 82 can push the moving seat 83 and the engraving head 9 to move longitudinally, thereby adjusting the longitudinal position of the engraving head 9.

[0028] Reference Figure 3 The inner wall of the fixed frame 4 is symmetrically provided with guide grooves 41, and a guide block 63 is slidably arranged inside the guide groove 41. The guide block 63 is fixedly connected to the clamping seat 6.

[0029] Here, by providing a guide groove 41 on the inner wall of the fixed frame 4 and a guide block 63, the stability of the movement of the clamping seat 6 can be improved.

[0030] Reference Figure 2 A collection box 11 is inserted into the bottom of the workbench 1, and a handle 111 is fixedly installed on the side wall of the collection box 11.

[0031] The collection box 11 and handle 111 are provided here to facilitate the collection of debris generated during workpiece engraving.

[0032] The implementation principle of a precision engraving machine with rapid positioning according to an embodiment of this application is as follows: During use, the device is placed in a designated position and the power is turned on. The workpiece is then placed inside the clamping seat 6. The electric push rod 5 is activated according to the size of the workpiece, pushing the clamping seat 6 closer to the workpiece. In conjunction with rotating the threaded rod 61, the threaded rod 61 pushes the clamping plate 62 downwards, thus fixing and clamping the workpiece. The engraving head 9 is then activated to perform the engraving operation on the workpiece. Secondly, the device can activate the drive motor 21, which drives the worm gear 22 to rotate. The worm gear 22 meshes with the worm wheel 23, driving the rotating shaft 3 and the fixed frame 4 to rotate, allowing the workpiece to rotate and the engraving angle to be adjusted. Furthermore, when the fixed frame 4 rotates 180 degrees, the workpiece can be flipped for engraving, improving the practicality of the device.
