Description

Technical Field

[0001] This utility model relates to the field of CNC machining, and in particular to a frame structure for an engraving machine and an engraving machine. Background Technology

[0002] Traditional CNC engraving machines often use segmented manufacturing and bolted connections for their gantry frames. This results in problems such as insufficient rigidity at the joints, inconsistent thermal deformation, and significant vibration transmission, affecting machining accuracy. Existing technologies typically address these issues by employing complex compensation algorithms or increasing material thickness, leading to increased costs. Utility Model Content

[0003] This utility model provides a frame structure for a carving machine and a carving machine, which solves at least one of the above-mentioned technical problems.

[0004] This utility model embodiment provides a frame structure for a carving machine. The frame structure is integrally formed and includes a base part, a crossbeam part, and two support parts symmetrically arranged between the base part and the crossbeam part. A crossbeam groove is provided on the crossbeam part along the length direction of the crossbeam part for accommodating a transverse lead screw. One end of the crossbeam part is provided with a motor mounting position for installing a motor, and the motor is used to drive the transverse lead screw to rotate.

[0005] In some embodiments, a transverse track mounting portion is further provided on the crossbeam portion along its length for mounting a transverse track. The transverse track is used to mount an engraving actuator, enabling its transverse movement. This engraving actuator includes, but is not limited to, a cooling fan, a motor, a tool-changing spindle, and a tool head. Furthermore, the engraving actuator can also be equipped with a vertically moving motor, track, and longitudinal lead screw to enable its vertical movement.

[0006] In some embodiments, the transverse rail mounting portion includes a first transverse rail mounting portion and a second transverse rail mounting portion; wherein the first transverse rail mounting portion is disposed on the top of the crossbeam portion, and the second transverse rail mounting portion is disposed on the front side of the crossbeam portion.

[0007] In this embodiment, two transverse rails are installed at two locations on the crossbeam, one for the first transverse rail mounting part and the other for the second transverse rail mounting part, which are used together to mount the engraving execution mechanism, thereby improving the stability of the engraving execution mechanism.

[0008] In some embodiments, the base portion is provided with a depth track mounting portion for mounting a depth track, wherein the depth track is perpendicular to the transverse track.

[0009] In some embodiments, the depth rail mounting portion includes a first depth rail mounting portion and a second depth rail mounting portion, and a recess is provided between the first depth rail mounting portion and the second depth rail mounting portion for accommodating a depth direction lead screw.

[0010] In this embodiment, by setting two parallel first depth track mounting parts and a second depth track mounting part, the stability of the track installed on the track mounting part and the engraving platform supported by the track is ensured. Furthermore, a recessed part is set between the two depth track mounting parts to accommodate the depth direction lead screw, which not only further reduces the weight of the frame structure but also provides installation space for the depth direction lead screw. The engraving machine using the frame structure of this application is also equipped with a motor to drive the depth direction lead screw, which is movably mounted to the engraving platform to drive the engraving platform to move in the depth direction.

[0011] In some embodiments, the rear part of the frame structure is configured as a hollow structure, and the hollow structure is provided with reinforcing ribs.

[0012] In this embodiment, by setting the frame structure to a hollow structure, the weight of the frame structure is reduced. Furthermore, to ensure the structural strength of the frame structure, reinforcing ribs are added to the hollow structure. Thus, the frame structure in this application reduces weight while ensuring high structural strength.

[0013] In some embodiments, the frame structure is mounted inside the engraving machine housing via the base portion, where the thickness of the base portion along the depth direction is greater than the thickness of the two support portions along the depth direction. In this embodiment, by making the thickness of the base portion along the depth direction greater than the thickness of the support portions along the depth direction, the overall thickness of the base is greater than that of the support portions located above it, thus improving the stability of the frame structure when installed in the engraving machine. Furthermore, it facilitates the installation of depth tracks along the depth direction.

[0014] In some embodiments, the length of the base portion along the length direction of the crossbeam portion is less than the length of the crossbeam portion.

[0015] In some embodiments, the support portion includes a vertical support portion and an inclined connecting portion, the upper end of the vertical support portion is connected to one end of the crossbeam portion, the lower end of the vertical support portion is connected to the upper end of the inclined connecting portion, and the lower end of the inclined connecting portion is connected to one side of the base portion.

[0016] In this embodiment, the frame structure is designed with a small thickness in the depth direction of the base and a small length in the length direction of the beam. This ensures the stability of the frame installation structure when it is installed in the engraving machine housing, and also reduces the lateral space occupied by the base when it is installed in the engraving machine housing. This allows the spaces on the front and rear sides of the frame structure inside the engraving machine housing to be better connected, facilitating the smooth discharge of processing debris from the front space of the frame structure to the rear space.

[0017] This utility model embodiment also provides an engraving machine, which includes a housing and a frame structure installed within the housing. An engraving platform and an engraving execution mechanism are mounted on the frame structure. The frame structure adopts the frame structure described in any embodiment of this application. The engraving platform can be mounted on a depth track mounting part of the base via a depth track, and the engraving execution mechanism can be mounted on a transverse track of the crossbeam via a transverse track.

[0018] The beneficial effects of this utility model embodiment are as follows: the base part, support part and crossbeam part are set as an integral frame structure, and a motor mounting position for installing the motor and a crossbeam groove for accommodating the transverse lead screw are provided on the integrally formed crossbeam part, which improves the stability of the entire frame structure, and there are no problems such as vibration transmission between the parts that affect the processing accuracy of the engraving machine.

A slide rail structure (or slide path structure) is provided on the side of the transverse movable component 420 opposite to the longitudinal movable component 410. These components cooperate with the longitudinal movable component 410 to achieve the vertical movement of the engraving actuator 400. The transverse movable component 420 includes a first extension 421 and a second extension 422 that are perpendicular to each other. The first extension 421 extends along the depth direction of the engraving machine (i.e., from the front to the rear of the engraving machine), and the second extension 422 extends along the longitudinal direction of the engraving machine. The lower surface of the first extension 421 is provided with a slide structure for mounting with the first transverse guide rail installed on the crossbeam 320; the inner surface of the second extension 422 is provided with a slide structure for mounting with the second transverse guide rail installed on the crossbeam 320.
