Description

Technical Field

[0001] This utility model relates to the field of machining center technology, specifically to a machining center cutting mechanism and a machining center thereof. Background Technology

[0002] CNC milling machines are automated machining equipment developed from general milling machines. The machining processes are basically the same, and their structures are also somewhat similar. CNC milling machines are divided into two main categories: those without a tool magazine and those with a tool magazine. CNC milling machines with a tool magazine are also known as machining centers.

[0003] When cutting, cutting fluid needs to be injected into the cutting area. Existing devices have a fixed injection angle for the cutting fluid injection device. When facing different cutting requirements of parts, it is difficult to accurately inject the cutting fluid into the cutting area. It is inconvenient to disassemble and reassemble the injection device. Therefore, we propose a cutting mechanism for machining center and its machining center. Utility Model Content

[0023] 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.

[0024] Example

[0025] Please see Figures 1-5 The figure shows a machining center cutting mechanism, including an adjuster 2, an injection cylinder 6, and a drive assembly 14. A mounting base 3 is fixedly mounted on the bottom of the adjuster 2. A cutting head 4 is fixedly mounted on the bottom of the mounting base 3. A mounting plate 7 is fixedly mounted on the outer side of the mounting base 3. A base 8 is located at the bottom of the mounting plate 7. A first electric push rod 9 is fixedly mounted on the bottom of the base 8. A mounting bracket 10 is fixedly mounted on the output end of the first electric push rod 9. A second electric push rod 11 is fixedly mounted inside the mounting bracket 10. A fixing rod 12 is fixedly mounted inside the mounting bracket 10. The injection cylinder 6 contains a component for fixing the rod 12. The sliding hole 13, the output end of the second electric push rod 11 is rotatably connected to the injection cylinder 6, the second electric push rod 11 and the fixed rod 12 are respectively provided at both ends of the mounting frame 10, and the second electric push rod 11 is located at the end of the mounting frame 10 near the cutting head 4. Furthermore, the output direction of the second electric push rod 11 has an angle with the vertical direction, and the angle is 20°. By pushing the injection cylinder 6 through the second electric push rod 11, the injection end of the injection cylinder 6 is moved downward or upward, thereby adjusting the injection angle of the injection cylinder 6 in the vertical direction.

[0026] The drive assembly 14 is located on the outside of the mounting plate 7 and is used to assist in adjusting the injection position of the injection cylinder 6. By rotating the toothed ring 17, the injection cylinder 6 is driven to move in a circular motion around the cutting head 4, which can adjust the injection position of the injection cylinder 6 in the horizontal direction.

[0027] The following describes some embodiments of this application in detail with reference to the accompanying drawings:

[0028] Please see Figures 1-5 The driving component 14 drives the injection cylinder 6 to rotate around the cutting head 4. In addition, the second electric push rod 11 pushes the injection cylinder 6 downward to adjust the tilt angle of the injection cylinder 6 in the vertical direction, thereby completing the adjustment of the cutting fluid injection angle.

[0029] There are two injection cylinders 6, which are symmetrically arranged on both sides of the cutting head 4. By setting two symmetrically distributed injection cylinders 6, each injection cylinder 6 can rotate 180° under the drive of the toothed ring 17. This ensures that the cutting fluid can be injected into the designated position in the circumferential area of ​​the part, while preventing the pipes connected to the outside of the injection cylinder 6 from getting tangled.

[0030] In addition, the drive assembly 14 includes a drive motor 15, which is fixedly mounted on the top of the mounting plate 7. A drive gear 16 is fixedly mounted on the output end of the drive motor 15. The drive gear 16 is located at the bottom of the mounting plate 7. A gear ring 17 is rotatably mounted on the bottom of the mounting plate 7. The gear ring 17 meshes with the drive gear 16. The base 8 is fixedly mounted on the bottom of the gear ring 17. The drive motor 15 drives the drive gear 16 to rotate, which in turn drives the gear ring 17 to rotate, thereby driving the injection cylinder 6 to rotate horizontally outside the cutting head 4.

[0031] It is worth noting that an insert 18 is fixedly provided on the side of the top of the base 8 away from the toothed ring 17, and an annular groove 19 is provided at the bottom of the mounting plate 7. The insert 18 is slidably disposed in the annular groove 19, thereby improving the connection strength between the base 8 and the mounting plate 7.

[0032] At the same time, the width of the sliding hole 13 is equal to the outer diameter of the fixed rod 12, which can prevent the syringe 6 from moving up and down freely within the mounting bracket 10;

[0033] In addition, a telescopic rod 20 is provided on the outside of the first electric push rod 9. The two ends of the telescopic rod 20 are fixed to the base 8 and the mounting frame 10 respectively. The setting of the telescopic rod 20 can restrict the movement direction of the mounting frame 10, ensuring that the mounting frame 10 can move up and down in the vertical plane with the syringe 6.

[0034] In this technical solution, a machining center includes a body 1, a movable worktable, and the aforementioned machining center cutting mechanism. An adjuster 2 is fixedly connected to the movable worktable, which is located and moves within the body 1. A control console 5 is fixedly provided on the outside of the body 1.

[0035] The principle behind this technical solution for adjusting the injection angle of the cutting fluid is as follows:

[0036] First, the drive motor 15 drives the drive gear 16 to rotate. The drive gear 16 drives the gear ring 17 to rotate at the bottom of the mounting plate 7 through meshing. This causes the two bases 8 fixed on the gear ring 17 to rotate synchronously, thereby causing the mounting bracket 10 and the injection cylinder 6 to make a circular motion around the cutting head 4, thereby adjusting the horizontal position of the injection cylinder 6, that is, adjusting the horizontal injection position of the cutting fluid.

[0037] Then, the first electric push rod 9 drives the mounting bracket 10 and the injection cylinder 6 to move up and down together. At the same time, the second electric push rod 11 pushes the injection cylinder 6 downward, causing the injection cylinder 6 to adjust the injection angle under the limit of the fixed rod 12, thereby realizing the adjustment of the vertical injection angle of the injection cylinder 6, that is, completing the adjustment of the vertical injection angle of the cutting fluid.

[0038] This allows for the adjustment of the injection angle of the cutting fluid in the syringe 6.

[0039] In this technical solution, the controller 5 controls the operation of the regulator 2 and the cutting head 4 to cut the parts fixed inside the machine body 1. During the cutting process, the cutting fluid is injected into the cutting area in real time through the above steps to ensure the normal cutting of the parts.
