Description

Technical Field

[0001] The utility model belongs to the technical field of CNC machining equipment, and particularly relates to CNC machining equipment with convenient tool replacement. Background Art

[0002] CNC machining equipment refers to mechanical machining equipment that operates and is controlled by computer numerical control technology. These equipment automatically perform machining through pre-set programs and can achieve high-precision and high-efficiency machining processes. The publication number CN217966075U discloses an automatic loading and unloading device for CNC machining, including a workbench and a machining device. One side of the lower surface of the workbench is fixedly connected with a first motor, the output end of the first motor is fixedly connected with a rotating shaft, and the bottom end of the rotating shaft is fixedly connected with a first gear. The side wall of the first gear is meshed with a second gear, the middle of the second gear is fixedly connected with a rotating rod, the upper end of the rotating rod penetrates to the upper end of the workbench and is fixedly connected with a fixed rod, one end of the fixed rod away from the rotating rod is fixedly connected with a fixed frame, the side of the fixed frame is fixedly connected with a second motor, the output end of the second motor extends into the fixed frame and is fixedly connected with a bidirectional threaded rod, the outer wall of the bidirectional threaded rod is threadedly connected with a threaded block, and the outer surface of the threaded block is fixedly connected with a clamping plate. Through the above structure, the material can be loaded and unloaded manually and automatically, and the material can be positioned. Although this kind of machining equipment has the effect of facilitating the loading and unloading of materials and positioning the materials, it is lacking in the disassembly and replacement of the tools of the machining equipment. Since this kind of machining equipment does not have a structure for quickly disassembling the tools, when the tool wears seriously and needs to be replaced, it will lead to the situation that the staff needs to use disassembly tools to disassemble the machining tool, resulting in a reduction in the tool replacement efficiency, and further leading to a reduction in the material processing efficiency.

Therefore, it should not be construed as a limitation to the present utility model.

[0028] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0029] In the embodiments of the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0030] In one embodiment of the present utility model, as Figures 1-4 shown, there is provided a CNC machining device for facilitating the replacement of a tool, including a base 1. A placement plate 2 is fixedly installed on the surface of the base 1. A motor A 3 is fixedly installed on the surface of the placement plate 2. A lead screw A 4 is installed at the output end of the motor A 3. A bracket 5 is slidably connected inside the placement plate 2. A cylinder 6 is fixedly installed inside the bracket 5. A cross plate 7 is installed at the output end of the cylinder 6. A motor B 8 is fixedly installed inside the cross plate 7. A lead screw B 9 is installed at the output end of the motor B 8. A connection block 10 is slidably connected inside the cross plate 7. A fixing frame 11 is fixedly installed on the surface of the connection block 10. A motor C 12 is fixedly installed on the surface of the fixing frame 11. A rotating plate 13 is installed at the output end of the motor C 12. An insertion block 15 is inserted inside the rotating plate 13. A tool bit 16 is fixedly installed on the surface of the insertion block 15. An insertion bar 14 is inserted inside the rotating plate 13. A rotating block 17 is rotatably connected to the surface of the rotating plate 13.

[0031] The CNC machining equipment with convenient tool replacement according to the embodiment of the present utility model only needs to turn on the motor A3 when machining a workpiece. The motor A3 drives the lead screw A4 to rotate. When the lead screw A4 rotates, it drives the bracket 5 to move in the placement plate 2, thereby driving the cross plate 7 to move horizontally. Then turn on the motor B8, and the motor B8 drives the lead screw B9 to rotate. When the lead screw B9 rotates, it drives the motor C12 and the tool bit 16 to move longitudinally through the connecting block 10 and the fixing bracket 11. When disassembling, installing and replacing the tool bit 16, only need to rotate the rotating block 17. After the rotating block 17 is turned away from the inserting strip 14, the inserting strip 14 can be pulled out from the rotating plate 13. At this time, the tool bit 16 can be pulled out from the rotating plate 13 through the inserting block 15. Then insert the new tool bit 16 into the rotating plate 13 through the inserting block 15, insert the inserting strip 14 into the rotating plate 13, and finally connect the rotating block 17 to the inserting strip 14 by threading. At this time, the replacement of the tool bit 16 is completed. When clamping and fixing workpieces of different sizes, only need to turn on the electric push rod 18. The electric push rod 18 drives the L-shaped plate 20 to slide in the limiting groove 19 until the workpiece is clamped in the L-shaped plate 20. At this time, the soft pad 21 protects the surface of the workpiece, thereby avoiding wear on the surface of the workpiece.

[0032] In another embodiment, as Figures 1-4 shown, the lead screw A4 is rotatably connected to the placement plate 2, and the bracket 5 is threadedly connected to the lead screw A4. Specifically, the threaded connection design between the lead screw A4 and the bracket 5 has the effect of driving the bracket 5 to move in the placement plate 2 when the lead screw A4 rotates.

[0033] In another embodiment, as Figures 1-4 shown, the lead screw B9 is rotatably connected to the bracket 5, and the connecting block 10 is threadedly connected to the lead screw B9. Specifically, the threaded connection design between the lead screw B9 and the connecting block 10 has the effect of driving the fixing bracket 11 to move through the connecting block 10 when the lead screw B9 rotates.

[0034] In another embodiment, as Figures 1-4 shown, the inserting strip 14 is slidably connected to the inserting block 15, and the rotating block 17 is threadedly connected to the inserting strip 14. Specifically, the sliding design between the inserting strip 14 and the inserting block 15 has the effect of facilitating the fixing of the tool bit 16 in the rotating plate 13 through the inserting block 15, and the threaded connection design between the rotating block 17 and the inserting strip 14 has the effect of facilitating the fixing of the inserting strip 14.

[0035] In another embodiment, as Figures 1-4 shown, the L-shaped plate 20 is slidably connected to the limiting groove 19, and the material of the soft pad 21 is natural rubber. Specifically, the sliding design between the L-shaped plate 20 and the limiting groove 19 has the effect of limiting the L-shaped plate 20 when the L-shaped plate 20 moves.

[0036] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
