Description

Technical Field

[0001] The utility model belongs to the field of engraving machines, and particularly relates to a transmission device for an engraving cutter head and an engraving machine. Background Art

[0002] Sculpture is a plastic art, a visual art of three-dimensional images made of material materials and means. Sculpture was originally mainly created by carving (shaping by subtracting materials) and molding (shaping by stacking materials) on materials such as stone, metal, wood, and ceramics. However, modern sculptures have a high degree of freedom in materials and creation techniques, and can be created on various different materials by using carving, welding, molding or casting methods. With the development of technology, sculpture engraving can be completed by an engraving machine. At the same time, the engraving machine can engrave digital sculptures in large quantities and with high precision, which is suitable for application in the product production of enterprises.

[0003] An engraving machine usually includes a base, a transmission device and an engraving cutter head. The transmission device can be further divided into a left-right movement mechanism, an up-down movement mechanism and a rotation mechanism; the engraving cutter head is installed on the rotation mechanism, and the rotation mechanism is used to drive the engraving cutter head to rotate; the rotation mechanism is installed on the up-down movement mechanism, and the up-down movement mechanism is used to drive the engraving cutter head to move up and down relative to the base; the up-down movement mechanism is installed on the left-right movement mechanism, and the left-right movement mechanism is used to drive the engraving cutter head to move left and right relative to the base. The left-right movement mechanism is then installed on the base through two oppositely arranged columns. When the engraving machine is in use, it is necessary to ensure the engraving accuracy. Therefore, the left-right movement mechanism and the up-down movement mechanism usually adopt the transmission form of a lead screw and an optical axis. In addition, since the engraving cutter head, the rotation mechanism and the up-down movement mechanism have a certain weight, in the prior art, the two ends of the lead screw and the optical axis are usually fixed to the column by a plurality of bolts or screws. However, during the processing of the bolt holes or threaded holes, due to processing errors, the hole diameter becomes larger or the distance between adjacent holes has an error. After the lead screw and the optical axis are fixed to the column, their transmission accuracy does not meet the standard, resulting in a lower engraving accuracy when the subsequent engraving cutter head engraves the workpiece.

[0028] In one embodiment, the left - right moving mechanism 100 further includes a second mounting member 9, a third fixing member 11, and a fourth fixing member 12; a second T - shaped groove is further provided on the side surface of the second column 8; the side surface provided with the second T - shaped groove is adjacent to the side surface provided with the first T - shaped groove; the first optical axis 3 is connected to the second mounting member 9, and a second through - hole 91 is further provided on the second mounting member 9; the third fixing member 11 is disposed in the second T - shaped groove, and the fourth fixing member 12 passes through the second through - hole 91 and is connected to the third fixing member 11 for fixing the second mounting member 9 and the third fixing member 11 on the second column 8.

The third fixing member 11 may also be a block - shaped structure adapted to the shape of the T - shaped groove, and the fourth fixing member 12 may also be a fixing structure such as a screw.

[0029] Please refer to Figure 6 , in this embodiment, the second mounting member 9 is a T - shaped block structure.

In other implementation manners, the second mounting member 9 may also be an L - shaped structure or other structural forms. For example, when the second mounting member 9 is an L - shaped structure, a second through - hole 91 for the fourth fixing member 12 to pass through is provided on its short - side, and the long - side is used for connecting to the first optical axis 3. This embodiment does not limit this.

[0030] The second mounting member a92 is provided with a third through hole 921 for mounting the first optical axis 3 and a groove 922 for dividing one end of the second mounting member 9 away from the second mounting member b93 into a first cantilever beam structure 923 and a second cantilever beam structure 924.

Specifically, the groove 922 is a rectangular groove structure penetrating one end of the second mounting member a92 away from the second mounting member b93, and the groove 922 can divide one end of the second mounting member a92 away from the second mounting member a92 away from the second mounting member b93 into two parts to form a first cantilever beam structure 923 and a second cantilever beam structure 924. The fifth fixing member 13 can be a bolt structure.

It can be understood that the diameter of the third through hole 921 provided in the second mounting member a92 can be greater than or equal to the diameter of the first optical axis 3 to facilitate the smooth installation of the first optical axis 3 into the third through hole 921.

[0031] Please refer to Figures 1-5, in one embodiment, the vertical movement mechanism 200 includes a second drive motor 14, a second lead screw 15, a second optical axis 16 and a second mounting seat 17; the first mounting seat 4 is of a U-shaped structure; the bottom of the first mounting seat 4 is connected to the first optical axis 3 and the first lead screw 2; both ends of the second optical axis 16 are respectively connected to one of the inner side walls of the first mounting seat 4; a fifth through hole is provided on one of the inner side walls of the first mounting seat 4, one end of the second lead screw 15 is rotatably connected to the inner side wall of the first mounting seat 4 without the fifth through hole, and the other end passes through the fifth through hole and is connected to the second drive motor; the second mounting seat 17 is connected to the second optical axis 16 and the second lead screw 15, and the rotation mechanism 300 is arranged on the second mounting seat 17. Specifically, the bottom of the first mounting seat 4 is connected to the first lead screw 2 through a lead screw nut. The fifth through hole can be provided on the inner side wall above the first mounting seat 4, and the second drive motor 14 is arranged on the outer side wall above the first mounting seat 4. In this embodiment, the first mounting seat 4 is provided with a U-shaped structure. On the one hand, it provides an installation place for the second lead screw 15 and the second optical axis 16. On the other hand, the two inner side walls of the first mounting seat 4 also play a role in mechanically limiting the second mounting seat 17, restricting the maximum distance of the upward or downward movement of the second mounting seat 17, preventing the engraving cutter head 500 from colliding with the workbench 600 of the engraving machine or preventing the rotation mechanism 300 from colliding with the outer shell at the top of the engraving machine.

[0032] The vertical movement mechanism 200 further includes a plurality of support columns 18, and the plurality of support columns 18 are spaced apart on the outer side wall of the first mounting seat 4 provided with the fifth through hole, and the ends of the plurality of support columns 18 away from the first mounting seat 4 are connected to the second drive motor 14. The plurality of support columns 18 are spaced apart on the outer side wall of the first mounting seat 4 with the fifth through hole as the center point. In this embodiment, the support columns 18 are arranged in 4 numbers, and the 4 support columns 18 form a rectangular structure with the point on the central axis of the fifth through hole as the center to install the drive motor. Through the arrangement of the support columns 18 in this embodiment, there is a certain gap between the second drive motor 14 and the outer side wall of the second mounting seat 17, and this gap can be used to provide an installation place for structures such as couplings for installing the first lead screw 2 on the drive shaft of the second drive motor 14, avoiding the structures such as couplings occupying the space inside the U-shaped structure of the second mounting seat 17, resulting in a reduction in the distance of the up and down movement of the engraving cutter head 500.

[0033] On the other hand, the present utility model also provides a carving machine, which includes a transmission device of a carving tool head 500 as described above, and further includes a base 400 and a carving tool head 500. The carving tool head 500 is arranged on a rotating mechanism 300, and a first column and a second column 8 are arranged on the base 400 at intervals. At the connection between the base 400 and the first column and the second base 400, a plurality of rib plates can be arranged to support the first column and the second column 8, ensuring that the first column and the second column 8 can be stably installed on the base 400. Further, two rib plates can be arranged, one rib plate corresponding to the first column and the other rib plate corresponding to the second column 8, and the installation positions of the rib plates are on the front side walls of the first column and the second column 8, so as to balance the weights of the up-and-down moving mechanism 200, the rotating mechanism 300 and the carving tool head 500, and ensure the smooth movement of the transmission mechanism.

[0034] A workbench 600 is further arranged on the base 400, and a plurality of third T-shaped grooves are arranged on the workbench 600, and the plurality of third T-shaped grooves penetrate through the workbench 600 in the left-right direction. The arrangement of the third T-shaped grooves facilitates the quick and accurate fixation of the workpiece on the workbench 600.

The front-and-back moving mechanism 700 includes: a third driving motor 20, a third lead screw 21 and a third optical axis 22. One end of the third lead screw 21 is connected to the third driving motor 20, and the other end is rotatably arranged on the base 400; both ends of the third optical axis 22 are respectively connected to the base 400; the workbench 600 is connected to the third lead screw 21 and the third optical axis 22, and the driving motor is used to drive the workbench 600 to move back and forth. Two third optical axes 22 can be arranged, which are respectively arranged on the opposite sides of the third lead screw 21, so as to ensure the smooth operation of the workbench 600. By arranging the front-and-back moving mechanism 700 on the base 400 to move the workbench 600, the load borne by the column is reduced, and the operation accuracy and smoothness of the carving tool head 500 are ensured.

[0036] In an embodiment, there are two up-and-down moving mechanisms 200, rotating mechanisms 300 and carving tool heads 500, and the up-and-down moving mechanisms 200, rotating mechanisms 300 and carving tool heads 500 are arranged in one-to-one correspondence, that is, the carving machine in this embodiment is a double-head carving machine, and the double-head carving machine can process different workpieces simultaneously, improving its production efficiency.
