[0038] In existing engraving machine equipment, the connection between the main unit and the Z-axis motion mechanism generally adopts a traditional mechanical screw fixing structure. The main unit body and the Z-axis guide component are rigidly connected by screws or bolts, and the fastening is achieved by threaded engagement. However, with this fixing structure, when installing or disassembling the main unit, users need to use special tools (such as wrenches, screwdrivers, etc.) to tighten or loosen multiple screws one by one, which is a cumbersome and time-consuming operation.

[0039] This utility model proposes a laser engraving machine.

[0040] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the laser engraving machine 100 includes:

[0041] Base 1;

[0042] Column structure 2 is fixedly mounted on base 1;

[0043] Mounting box 3 is slidably disposed along the axial direction of column structure 2, and mounting box 3 is provided with clamping cavity and mounting port 30 communicating with clamping cavity; and

[0044] The engraving machine body 4 has a mounting handle 41 that is detachably inserted into the clamping cavity through the mounting port 30.

[0045] The technical solution of this utility model involves setting a liftable mounting box 3 on the column structure 2, and providing a mounting port 30 on the mounting box 3 for inserting and fixing the mounting handle 41 of the engraving machine body 4. When installing the engraving machine body 4, the user simply aligns the mounting handle 41 of the engraving machine body 4 with the mounting port 30 of the mounting box 3, and then inserts it into the clamping cavity along the mounting port 30. When disassembling the engraving machine body 4, the user simply pulls the engraving machine body 4 outwards gently to overcome the resistance of the elastic clamping device, thus pulling the mounting handle 41 out of the clamping cavity and completing the disassembly process. Furthermore, the sliding of the mounting box 3 along the axial direction of the column structure 2 allows the engraving machine body 4 to rise or fall, achieving adjustment of the engraving height of the engraving machine body 4. In this solution, the engraving machine body 4 and the mounting box 3 are connected by a plug-in method to achieve quick installation and disassembly, without the need for additional auxiliary tools, making the installation and disassembly of the engraving machine body 4 easy.

[0046] Specifically, the base 1 can adopt a prism or cylindrical structure. The size of the base 1 is not specifically limited and can be selected according to the actual application scenario. The base 1 can be made of high-strength materials such as stainless steel or aluminum alloy to stably support the engraving machine body 4. The base 1 may include a large base plate, a removable base plate, and foot pads. The removable base plate is located below the engraving machine body 4 and embedded above the large base plate. This facilitates the user's cleaning of engraving debris and dust. The user can remove the removable base plate to clean residue generated during the engraving process, maintaining cleanliness. Furthermore, the removable base plate can accommodate different processing needs. By removing the removable base plate and placing it directly under the material to be processed, free-plane processing is possible, allowing the user to engrave or cut within a wider range, overcoming the limitations of base plate size and improving processing flexibility and adaptability. The foot pads are located below the large base plate to prevent movement during use and also serve to absorb shock and prevent slippage. The column structure 2 is fixedly mounted on the base 1 and serves to connect the base 1 and the mounting box 3. It can be a cylindrical metal rod with a guide groove or track inside to ensure that the mounting box 3 can slide stably along its axis and ensure the stability of the mounting box 3 at different height positions, thereby indirectly affecting the accuracy of the working position of the laser engraving machine 100 body.

[0047] It should be noted that the clamping cavity can also be equipped with an elastic clamping device (such as a spring clip or rubber pad). After the mounting handle 41 is inserted, the elastic clamping device will be compressed and automatically clamp the mounting handle 41. When the mounting handle 41 is fully inserted, the elastic rubber pad will restore some of its deformation and tightly clamp the mounting handle 41, ensuring that the engraving machine body 4 will not loosen during operation. During disassembly, the mounting handle 41 is pulled outward, and the elastic rubber pad is compressed again, making it easy for the mounting handle 41 to be pulled out smoothly. In addition, a slot can be provided inside the mounting box 3, and a clip can be provided on the mounting handle 41. The clamping action of the mounting handle 41 is achieved by the engagement and fixation of the clip and the slot.

[0048] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 The mounting box 3 includes an upper cover 31 and a lower box 32. The lower box 32 has a mounting opening 30 on its side and a notch on its top surface. The upper cover 31 and the lower box 32 are rotatably connected to open or close the notch, allowing the upper cover 31 to release or clamp the mounting handle 41 of the engraving machine body 4. When the engraving machine body 4 needs to be installed, rotate the upper cover 31 to open the notch, insert the mounting handle 41 of the engraving machine body 4 into the lower box 32 through the mounting opening 30 on the side of the lower box 32, and then rotate the upper cover 31 to close the notch, thus clamping the mounting handle 41. The operation is simple and efficient. For disassembly, the operation is reversed: first rotate the upper cover 31 to open the notch, and then pull out the mounting handle 41 from the mounting opening 30. The entire disassembly and assembly process is convenient and quick.

[0049] It is worth mentioning that the rotating connection structure between the upper cover 31 and the lower box 32 can be a hinge or a latch structure, and the inner surface of the upper cover 31 can be provided with protrusions or slots. During operation, when the upper cover 31 is rotated to close the notch, the protrusion on the upper cover 31 can cooperate with the corresponding structure inside the lower box 32, or the slot can lock a part of the structure of the mounting handle 41, thereby clamping the mounting handle 41 and ensuring the stability of the engraving machine body 4 during operation; when the upper cover 31 is rotated to open the notch, the protrusion separates from the structure inside the lower box 32, and the slot no longer locks the mounting handle 41, making it convenient to pull out or insert the mounting handle 41. Furthermore, the edge of the mounting opening 30 of the lower box 32 can be chamfered to facilitate the smooth insertion of the mounting handle 41.

[0050] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 The installation box 3 also includes a button lock assembly 33, which includes:

[0051] Locking groove 331 is located on the edge of the upper cover 31 and near the lower box 32; and

[0052] The button buckle 332 is rotated and located on the edge of the lower box 32 to separate from or engage with the locking groove 331.

[0053] Specifically, the push-button lock assembly 33 includes a lock groove 331 and a push-button buckle 332. The lock groove 331 can be a U-shaped recessed structure. The opening of the lock groove 331 can be provided with a limiting protrusion with a certain roughness. A tongue is provided on the push-button buckle 332 near the limiting protrusion. When the push-button buckle 332 rotates to the position where it engages with the lock groove 331, the tongue structure on the push-button buckle 332 will embed into the lock groove 331 and abut against the limiting protrusion. The limiting protrusion structure on the inner wall of the lock groove 331 can increase the friction and engagement strength between the push-button buckle 332, ensuring that the upper cover 31 is in a closed and locked state. The push-button buckle 332 is rotatably located at the edge of the lower box 32. For example, the push-button buckle 332 can be a metal piece with a tongue structure, one end of which is connected to the edge of the lower box 32 via a pivot pin, allowing it to rotate around the pivot pin. When the top cover 31 needs to be opened, the operator can manually press the button latch 332, causing the tongue part of the button latch 332 to rotate and disengage from the locking groove 331. The setting of the button lock assembly 33 increases the clamping force of the top cover 31 on the mounting handle 41, further improving the fixing strength of the engraving machine body 4 and ensuring that the engraving machine body 4 can remain stable during the engraving process.

[0054] In the embodiments of this utility model, please refer to Figure 3 and Figure 4The push-button lock assembly 33 also includes a first rotating shaft 333 and a first elastic reset member (not shown). The first rotating shaft 333 is fixedly disposed on the outside of the lower box 32, the first elastic reset member is sleeved on the outer periphery of the first rotating shaft 333, and the push-button buckle 332 is disposed on the outer periphery of the first elastic reset member, with both ends of the first elastic reset member connected to the push-button buckle 332 and the lower box 32 respectively. The first rotating shaft 333 can be a metal cylindrical shaft, and its two ends can be fixed to the outer wall of the lower box 32 by nuts or welding, serving to support and position the push-button buckle 332. During the opening or closing of the upper cover 31, the push-button buckle 332 rotates around the first rotating shaft 333. The first rotating shaft 333 provides a stable axis for the rotation of the push-button buckle 332, ensuring the smoothness of the push-button buckle 332 during rotation, so that the push-button buckle 332 can accurately engage or disengage from the lock groove 331. The first elastic reset element can be a coil spring, such as a torsion spring, or other elastic structure capable of generating torsional force. When the button 332 is pressed, the button 332 compresses the first elastic reset element, which stores elastic potential energy. When the button 332 is released, the first elastic reset element releases the elastic potential energy, causing the button 332 to spring back to its initial position, thereby achieving the automatic reset function of the button 332. This ensures that the button 332 is in the correct position after operation, guaranteeing the normal operation of the button lock assembly 33.

[0055] In the embodiments of this utility model, please refer to Figure 3 The mounting box 3 also includes a second rotating shaft 34 and a second elastic reset member 35. The upper cover 31 and the lower box 32 are rotatably connected by the second rotating shaft 34 so that the upper cover 31 can be flipped relative to the lower box 32. The second elastic reset member 35 is sleeved on the outer periphery of the rotating shaft, and the two ends of the second elastic reset member 35 are respectively connected to the upper cover 31 and the lower box 32. The button buckle 332 is pressed to separate it from the lock groove 331, and under the action of the second elastic reset member 35, the upper cover 31 can swing away from the button lock assembly 33 to open the clamping cavity.

[0056] Specifically, the second rotating shaft 34 can be a metal cylindrical shaft, with both ends precisely installed in the corresponding shaft holes of the lower box 32 and the upper cover 31. Smooth rotation is ensured through interference fits or the use of bushings. During the closing and opening of the upper cover 31, the upper cover 31 rotates relative to the lower box 32 around the second rotating shaft 34. The second elastic reset member 35 is sleeved on the outer periphery of the second rotating shaft 34, with its two ends connected to the upper cover 31 and the lower box 32, respectively. For example, the second elastic reset member 35 can be a torsion spring structure. When the button buckle 332 engages with the lock groove 331, the second elastic reset member 35 is in a pre-tightened state, storing a certain amount of elastic potential energy. When the button buckle 332 is pressed, separating it from the lock groove 331, the second elastic reset member 35 releases its elastic potential energy, generating torque that causes the upper cover 31 to automatically swing open in a direction away from the button lock assembly 33. When closing the top cover 31, it is necessary to overcome the elastic force of the second elastic reset member 35, flip the top cover 31 back to its original position, and fix the position of the top cover 31 by the engagement of the button buckle 332 with the locking groove 331.

[0057] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 The mounting box 3 also includes a buffer pad 36, which is located on the side of the upper cover 31 facing the lower box 32. When the upper cover 31 is closed, the buffer pad 36 presses against the mounting handle 41 of the engraving machine body 4. The buffer pad 36 can be a rectangular or circular silicone pad with a thickness of 1-3cm. When the upper cover 31 is closed, the buffer pad 36 will contact the mounting handle 41 and be compressed, and will deform accordingly according to the shape of the mounting handle 41, thereby achieving the functions of protection, stability and shock absorption of the mounting handle 41.

[0058] In the embodiments of this utility model, please refer to Figure 3 The mounting box 3 also includes a clamping member 37, which is movably mounted on the lower box 32 and tends to move closer to or further away from the center of the clamping cavity to press against or release the mounting handle 41 of the engraving machine body 4 within the clamping cavity. When the mounting handle 41 is inserted into the clamping cavity, a movable clamping member 37 is provided to reduce the excess material between the outer wall of the mounting handle 41 and the cavity wall. The clamping member 37 may include an elastic post and a cap nut. The elastic post may be a columnar body with an internal spring structure. For example, the main body of the elastic post is made of metal, with a helical spring nested inside. A plunger head is located at one end of the elastic post, and the cap nut is fitted onto the other end of the elastic post, engaging with a threaded hole on the lower box 32 via threads. Before the mounting handle 41 is inserted into the clamping cavity, the elastic post extends outwards from the clamping cavity. After the mounting handle 41 is inserted into the clamping cavity, the elastic post extends inwards from the clamping cavity to press against the mounting handle 41 and is locked in place by the cap nut.

[0059] In the embodiments of this utility model, please refer to Figure 5 and Figure 6 The laser engraving machine 100 also includes a lifting structure 5, which is mounted on the column structure 2 and fixedly connected to the mounting box 3 to drive the mounting box 3 to rise or fall along the axial direction of the column structure 2. The lifting structure 5 can be a screw and nut mechanism or a hydraulic lifting mechanism, etc. When a hydraulic lifting mechanism is used, the cylinder body of the hydraulic cylinder is fixed inside the column housing 21, and the piston is fixedly connected to the mounting box 3. When hydraulic oil is input into the rodless chamber of the hydraulic cylinder, the piston moves upward under the action of oil pressure, driving the mounting box 3 to rise; when hydraulic oil is withdrawn from the rodless chamber, the mounting box 3 falls under its own weight and the action of the piston, thereby realizing the driving of the lifting and lowering of the mounting box 3.

[0060] In the embodiments of this utility model, please refer to Figure 5 and Figure 6 The column structure 2 includes a column housing 21, and the lifting structure 5 includes:

[0061] The lead screw 51 is rotatably disposed inside the column housing 21; and

[0062] The slider 52 is fixedly connected to the mounting box 3, and the slider 52 is connected to the lead screw 51 by a nut.

[0063] Specifically, in this embodiment, the lifting structure 5 is a lead screw and nut mechanism. The lead screw is a slender rod with trapezoidal threads, and its material can be high-strength alloy steel. It is mounted on the column housing 21 via bearings and can rotate freely around its own axis. The nut is used to connect the lead screw 51 and the mounting box 3 and matches the threads of the lead screw. When the mounting box 3 needs to be raised, the lead screw rotates in the forward direction, and the nut moves upward along the lead screw under the action of the lead screw threads, thereby driving the mounting box 3 to rise along the axial direction of the column structure 2; when it needs to be lowered, the lead screw rotates in the reverse direction, and the nut drives the mounting box 3 to move downward along the lead screw. In other embodiments, the lifting structure 5 may also include components such as a circuit board, a connector 6, a guide shaft, two limit switches, and a drive motor 53. The drive motor 53 drives the rotation of the lead screw 51. The connector 6 can be an L-shaped bracket, with one end of the bracket connected to the mounting box 3 and the other end connected to the nut. The guide shaft is arranged side by side on both sides of the lead screw to provide direction for the sliding of the slider 52. Two limit switches can be respectively installed at both ends of the lead screw 51 to limit the upper and lower displacements of the slider 52. The circuit board is located on the top of the column housing 21 and has three connection terminals for connecting the drive motor 53 and the two limit switches respectively.

[0064] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
