[0002] A CNC engraving machine is a device used for engraving. From a processing principle perspective, it is a combination of drilling and milling machining. CNC engraving machines have multiple data input modes, enabling flexible processing operations as needed. They are widely used in various fields, such as fine signage, text engraving, and precision machining of small soft metal products and miniature molds. However, current CNC engraving machines still have the following shortcomings:

[0003] For example, patent document CN222290434U discloses an engraving machine. This engraving machine can rigidly clamp the plate through two relatively distributed limiters. Compared with the existing elastic clamping, the plate will not loosen during engraving, and the clamping effect is significantly improved. However, its clamping of the tool is not stable enough, and it is easy to loosen during the engraving process, thus affecting the engraving quality.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a carving machine with stable tool clamping. Utility Model Content

The clamping assembly is located at the output end of the motor and includes a connecting plate, a sliding groove, a limiting sliding piece, a movable strip, a clamping piece, a fixing strip, a bidirectional screw, a handwheel, and a carving tool.

[0007] Furthermore, the connecting plate is connected to the motor output end via a coupling, and a sliding groove is provided on the lower side of the connecting plate, with a limiting sliding member slidably connected inside the sliding groove.

[0008] Furthermore, a movable strip is installed at the bottom of the limiting sliding member, and a clamping member is provided at the bottom of the movable strip.

[0009] Furthermore, fixing strips are installed on both sides of the lower surface of the connecting plate, and a bidirectional lead screw is rotatably connected to the inner side of the fixing strip. A handwheel is installed at the left end of the bidirectional lead screw, and the outer side of the bidirectional lead screw is threadedly connected to the inner surface of the movable strip.

[0014] This utility model provides a carving machine with stable tool clamping, which has the following beneficial effects:

[0015] 1. This utility model features a clamping assembly comprising a connecting plate, a sliding groove, a limiting sliding member, movable bars, clamping members, a fixing bar, a bidirectional lead screw, a handwheel, and an engraving tool. In use, the upper end of the engraving tool is placed between the inner sides of the clamping members. Rotating the handwheel causes the bidirectional lead screw to rotate along the inner side of the fixing bar, which in turn causes two sets of movable bars to move towards each other along the surface of the bidirectional lead screw. The movement of the movable bars is limited by the sliding connection between the limiting sliding member and the inner side of the sliding groove. The movable bars drive the two sets of clamping members to move towards each other, and the clamping members stably clamp and fix the clamping members. This allows for quick assembly and disassembly of the tool, and the clamping of the tool is very stable and not easily loosened during installation.

In use, the exhaust fan is activated, drawing out the waste chips generated inside the protective shell through the chip-collecting hood and transporting them to the chip-collecting box via the chip-collecting pipe. The chip-collecting mesh frame intercepts and collects the waste chips. The auxiliary handle moves the sealing plate backward, causing the chip-collecting mesh frame to move outward. The limiting strip, slidingly connected to the inner side of the limiting groove, limits the movement of the chip-collecting mesh frame, facilitating regular cleaning. This allows the device to collect waste chips generated during the engraving process, preventing chip accumulation from affecting the engraving process. Attached Figure Description
