Description

Technical Field

[0001] This utility model relates to the field of woodworking equipment, and in particular to a high-efficiency cutting structure for a CNC woodworking engraving machine. Background Technology

[0002] Wood carving machines are specialized tools used for carving wood crafts and producing furniture. They are highly automated, efficient, and versatile, capable of grooving, carving, and hollowing out. The gantry is moved to the desired carving position by the drive device, and then the cutting tool performs the operation under the drive of the CNC motor.

[0003] When the carving spindle of the existing wood carving machine needs to be changed, the gantry is controlled to move the carving spindle to the tool magazine. The tool change is then performed with the assistance of the operator. However, due to the relatively complex carving process, multiple tools need to be used alternately. Therefore, the operator needs to stop the machine during operation to change the tools, which results in long tool change time and inconvenience, thus reducing work efficiency. To address this issue, a high-efficiency cutting structure for CNC wood carving machines is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-efficiency cutting structure for a CNC wood carving machine, aiming to solve the problems of "long tool changing time and inconvenient tool changing reducing work efficiency" in the prior art.

[0013] The sleeve has an internal receiving cavity and a locking groove.

[0014] As a further description of the above technical solution:

[0015] The number of bumps is set to multiple, and the farthest distance between the surfaces of the multiple bumps is less than the inner diameter of the receiving cavity.

[0016] As a further description of the above technical solution:

[0017] The driving mechanism includes a bracket, which is fixedly connected to the top of the base. A hydraulic cylinder is fixedly connected to the inner wall of the bracket. A cylinder rod is provided at the bottom of the hydraulic cylinder, and the bottom of the cylinder rod is fixedly connected to the top of the wedge.

[0018] As a further description of the above technical solution:

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 2 The present invention provides an embodiment of a high-efficiency cutting structure for a CNC woodworking engraving machine, comprising a base 1, mounting plates 2 fixedly connected to the left and right sides of the base 1, mounting plates 2 having mounting holes 20 on their surfaces, and mounting plates 2 being fixed to the frame of the CNC woodworking engraving machine by bolts passing through the mounting holes 20 for easy installation; a fixing seat 3 fixedly connected to the bottom of the base 1, and a sleeve 8 provided at the bottom of the fixing seat 3, the central axis of the sleeve 8 coinciding with the central axis of the fixing seat 3, and a connecting mechanism 11 provided inside the sleeve 8.

[0031] Reference Figure 2 - Figure 4 The connecting mechanism 11 includes a wedge 4, the surface of which is provided with an inclined surface 5. The wedge 4 is slidably connected to the inner wall of the fixed base 3. The sliding direction of the wedge 4 is up and down. An elastic element 6 is fixedly connected to the bottom of the fixed base 3. When the elastic element 6 is not subjected to external force, it is naturally extended in a vertical strip shape. When the elastic element 6 is subjected to external force, it will undergo elastic deformation and bend. A protrusion 7 is fixedly connected to the side of the elastic element 6 away from the wedge 4. The cross section of the protrusion 7 is set as a semi-circle.

[0032] Reference Figure 2 - Figure 4The sleeve 8 has an internal cavity 9 for accommodating the wedge 4, the elastic element 6, and the protrusion 7. The sleeve 8 also has a locking groove 10. The number of protrusions 7 is set to multiple, and the farthest distance between the surfaces of the multiple protrusions 7 is less than the inner diameter of the cavity 9. When the inclined surface 5 of the wedge 4 presses the elastic element 6, the elastic element 6 deforms and bends outward, thereby allowing the protrusion 7 to enter the locking groove 10. The bottom of the sleeve 8 is fixedly connected to an installation rod 18, and the bottom of the installation rod 18 is provided with a threaded hole 19. Different types of tools can be installed in the threaded hole 19 at the bottom of the installation rod 18. When changing tools, different types of tools prepared in advance can be quickly changed by quickly replacing the sleeve 8.

[0033] Reference Figure 2 , Figure 3 A vertically positioned positioning rod 12 is fixedly connected to the center of the bottom of the inner wall of the sleeve 8. A positioning groove 13 that cooperates with the positioning rod 12 is provided at the bottom of the wedge block 4. The positioning rod 12 is inserted into the inside of the positioning groove 13. A drive mechanism 17 is provided at the top of the base 1.

[0034] Reference Figure 2 , Figure 4 The drive mechanism 17 includes a bracket 14 that supports the hydraulic cylinder 15. The bracket 14 is fixedly connected to the top of the base 1. The hydraulic cylinder 15 is fixedly connected to the inner wall of the bracket 14. A cylinder rod 16 is vertically arranged at the bottom of the hydraulic cylinder 15. The bottom of the cylinder rod 16 is fixedly connected to the top of the wedge block 4.

[0035] Working principle: In use, the base 1 is first fixed to the worktable of the CNC wood carving machine through the mounting holes 20 on the mounting plates 2 on both sides to ensure the stability and accuracy of the entire CNC wood carving machine. Then, the cutting head is installed on the sleeve 8 through the cooperation of the mounting rod 18 and the threaded hole 19. When the sleeve 8 needs to be installed, the sleeve 8 is first manually pushed to align with the wedge 4 and move upward, so that the positioning rod 12 enters the positioning groove 13, improving the installation accuracy. Since the farthest distance between the surfaces of the multiple protrusions 7 is less than the inner diameter of the receiving cavity 9, it is easy for the sleeve 8 to fit on the outside of the wedge 4. When the top of the sleeve 8 contacts the bottom of the fixed seat 3, the hydraulic cylinder 15 is activated. The cylinder rod 16 drives the wedge 4 to slide upward. The inclined surface 5 of the wedge 4 squeezes the elastic element 6, causing the elastic element 6 to deform, thereby driving the multiple protrusions 7 to move away from each other, and then the multiple protrusions 7 enter the clamping groove 10, thereby realizing the quick installation of the sleeve 8.

[0036] When the cutting head needs to be disassembled, the hydraulic cylinder 15 drives the wedge block 4 to move downward and reset, so that the elastic element 6 disengages from the inclined surface 5, and then the elastic element 6 returns to its initial vertical rod shape, thereby causing the protrusion 7 to disengage from the inside of the clamping groove 10. Then the entire sleeve 8 is removed, realizing the quick installation, disassembly and fixation of the cutting head, improving the working efficiency and operation convenience of the engraving machine.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
