[0002] A tool magazine engraving machine refers to a CNC engraving machine equipped with an automatic tool changer (tool magazine) for precision machining of equipment or various parts.

[0003] Existing tool magazine engraving machines typically have very high spindle speeds (usually reaching thousands or even tens of thousands of revolutions per minute) to achieve fine surface finishes and process materials with high hardness. During machining, the CNC system can automatically select the required tool from the tool magazine according to pre-programmed instructions (NC code), and the robotic arm (tool changer) will install the tool onto the spindle or return the tool from the spindle to the tool magazine. The tool changing process usually only takes a few seconds. However, existing tool magazine engraving machines have the following problems: 1. Thermal deformation of the traditional metal frame leads to long-term drift in machining accuracy; 2. Manual intervention is required for tool setting after automatic tool changing; 3. Frequent replacement of cutting fluid / high cost of waste disposal affects machining accuracy during fine machining, and labor and maintenance costs are high; 4. The machining accuracy for small workpieces is not high. Therefore, a high-precision fully automatic tool magazine engraving machine is proposed to solve the problems existing in the current technology. Utility Model Content

[0025] See Figure 1As shown, the technical solution adopted in this specific embodiment is as follows: It includes a frame cover 1 and a marble base 2. The frame cover 1 is installed on the marble base 2. A left-right translation axis assembly 17 is provided at the rear end of the marble base 2. An up-down lifting axis assembly 13 is provided on the left-right translation axis assembly 17. A front-back translation axis assembly 15 is axially provided in the middle of the marble base 2, extending below the left-right translation axis assembly 17. An automatic tool magazine assembly 14 is provided on one side of the front-back translation axis assembly 15, adjacent to the left-right translation axis assembly 17. A cutting fluid filter circulation assembly 10 is provided on the rear side of the marble base 2 near the left-right translation axis assembly 17. An automatic tool setter 16 is provided on the side of the front-back translation axis assembly 15 away from the automatic tool magazine assembly 14. In this embodiment, in order to improve the overall continuous operation performance of the equipment and avoid long-term operation... The thermal deformation caused by the heating of the machine frame can lead to drift in machining accuracy. The use of a marble base prevents thermal deformation during long-term operation, thus ensuring machining accuracy in terms of overall equipment stability. This embodiment is particularly designed for machining smaller workpieces and employs a three-axis motion system, including a vertical lifting axis assembly, a horizontal translation axis assembly, and a front-back translation axis assembly. The front-back translation axis assembly serves as the fixing mechanism for the workpiece, and it is equipped with several fixing screw holes to fix the workpiece fixture. The front-back translation axis assembly drives the workpiece to move back and forth in a plane on the marble base. The horizontal translation axis assembly, in conjunction with the vertical lifting axis assembly, drives the tool to move horizontally in a plane and vertically in a vertical direction. The vertical lifting axis assembly, the horizontal translation axis assembly, and the front-back translation axis assembly are all made of high-rigidity materials, thereby improving machining accuracy.

[0026] The machine is equipped with an automatic tool magazine assembly and an automatic tool setter inside the frame cover. Since different shapes of workpieces need to be processed, different tools need to be switched. Therefore, an automatic tool magazine assembly is set up to automatically change different tools according to the set program during the processing. After the tool change is completed, the automatic tool setter calibrates the replaced tool to ensure accurate tool replacement and effectively improve processing accuracy.

[0027] During the machining process, cutting fluid is sprayed onto the cutting tool to cool it down. The waste fluid generated is treated through a circulating filtration system. The multi-stage filtration and circulation components can filter out coarse and fine debris generated during machining, so that the filtered cutting fluid can be recycled. In contrast, traditional single-stage circulating filtration systems have poor filtration effects and require replacement of the cutting fluid after a period of use. However, the filtration and circulation system in this embodiment adopts a multi-stage filtration structure, which enables long-term recycling of the cutting fluid, thereby reducing the frequency of maintenance and reducing maintenance costs.

[0028] In this embodiment, fully automated multi-axis high-precision machining, combined with a marble base, effectively achieves high-stability, high-precision machining operations. Meanwhile, the automated tool changing-tool setting-machining closed-loop operation effectively improves machining efficiency, and the multi-stage cutting fluid filtration and circulation components enhance the recycling rate of cutting fluid, thereby reducing maintenance frequency and costs. This makes it suitable for high-precision machining of batch workpieces.

[0029] More specifically, the upper and lower lifting shaft assembly 13 includes a sliding plate 37, a lifting base plate 38, and a lifting guide rail 40. The bottom of the sliding plate 37 is slidably connected to the lifting guide rail 40 by clamping blocks.

A machining spindle 33 is provided at the lower front end of the sliding plate 37, and a milling cutter 3 is provided at the front end of the machining spindle 33. 5. An air blowing universal pipe 34 is also provided on the front side of the front end of the machining spindle 33, and a cutting fluid universal pipe 36 is provided on the outer side of the front end of the machining spindle 33. A cooling circulation pipe structure is also provided inside the machining spindle 33.

At the same time, a drag chain fixing plate is provided on the lifting base plate, and a drag chain is provided on the drag chain fixing plate to connect with the sliding plate, thereby constraining and protecting the lifting and lowering movement of the sliding plate.

[0030] The machining spindle generates a large amount of heat during operation, so a cooling circulation system is installed inside to inject coolant for cooling. At the same time, an air blowing universal pipe is installed to connect to an external air pump to blow air onto the machining area, removing the generated debris from the workpiece surface and ensuring machining accuracy. A cutting fluid universal pipe is also installed to spray cutting fluid onto the milling cutter and machining area to cool the workpiece and milling cutter, achieving the functions of cleaning and cooling the milling cutter, preventing damage to the milling cutter due to excessive temperature, and ensuring the machining accuracy of the machined parts.

[0031] More specifically, there are two lifting guide rails 40, and a lifting screw 39 is provided between the two lifting guide rails 40. One end of the lifting screw 39 is connected to the output shaft of the lifting motor 41, and the other end is connected to the front bearing of the lifting base plate 38. The lifting screw 39 also engages with the sliding block threaded on the back of the slide plate 37. In this embodiment, the drive motor is a high-precision servo motor, the lifting screw is a high-precision screw, and the screw and the slider are connected by threaded transmission. Under the drive of the drive motor, the precise linear motion of the machining spindle is achieved to perform precision machining in the depth direction.

[0032] More specifically, the left and right translation axis assembly 17 includes a left and right translation axis accordion cover 18, marble columns 19, and a base plate 191.

Two left and right translation guide rails 21 are symmetrically arranged on the base plate 191. Left and right translation slide plates 20 are slidably connected to the left and right translation guide rails 21. The left and right translation slide plates 20 are connected to the left and right translation axis accordion cover 18 on both sides. In this embodiment, by setting a retractable left and right translation axis accordion cover in conjunction with the left and right translation slide plates to cover the left and right translation guide rails, dust can be effectively prevented, preventing the entry of processing debris and dust, ensuring the stability of translation, and guaranteeing the processing effect.

[0033] A left-right translation screw 22 is provided between the two left-right translation guide rails 21 and is threadedly engaged with the left-right translation slide plate 20. One end of the left-right translation screw 22 is rotatably connected to the base plate 191, and the other end of the left-right translation screw 22 is provided with a left-right translation motor 23. The output shaft end of the left-right translation motor 23 is connected to the left-right translation screw 22. The left-right translation motor is also a high-precision servo motor, and the left-right translation screw is also a high-precision screw to ensure machining accuracy. Under the drive of the left-right translation motor, the left-right translation screw drives the left-right translation slide plate to move smoothly left and right, thereby driving the machining spindle to perform machining in the left-right plane direction.

[0034] The bottom of the base plate 191 is also provided with a left and right translation drag chain 24 connected to the left and right translation slide plate 20. The other end of the left and right translation drag chain 24 is connected to the upper cover 1 of the frame. The left and right translation drag chain restrains and protects the left and right translation slide plate.

[0035] More specifically, the front and rear translation axis assembly 15 includes a front and rear translation slide plate 25, a front and rear translation guide rail 26, and a front and rear translation base plate 27. Two front and rear translation guide rails 26 are symmetrically arranged on the front and rear translation base plate 27. The front and rear translation slide plate 25 is slidably connected to the front and rear translation guide rails 26. A front and rear translation motor 28 is provided at one end of the front and rear translation base plate 27 near the upper and lower lifting axis assembly 13.

The front and rear translation lead screw 30 is drively connected to the front and rear translation slide plate 25, and the front and rear translation slide plate 25... The front end of the lead screw 30 is rotatably connected to the front and rear translation base plate 27. The front and rear translation base plate 27 is also provided with a front and rear translation drag chain 29. The other end of the front and rear translation drag chain 29 is connected to the marble base 2. In this embodiment, the front and rear translation motor is also a high-precision servo motor, and the front and rear translation lead screw is also a high-precision lead screw. The workpiece is set on the front and rear translation slide plate. The front and rear translation motor drives the front and rear translation lead screw to rotate and drive the front and rear translation slide plate to move linearly back and forth along the front and rear translation guide rail. This, combined with the up and down and left and right movements of the machining spindle, achieves three-axis precision machining.

[0036] More specifically, the automatic tool magazine assembly 14 includes a tool magazine cover 43, an automatic tool magazine motor 42 is mounted on the top of the cover 43, a tool magazine cover plate 44 is vertically mounted on one side inside the cover 43, a tool magazine turntable 45 is mounted on one side of the cover 44 and connected to the rotating shaft of the automatic tool magazine motor 42, and tool holder grippers 46 are evenly arranged around the turntable 45, with tool holders 47 engaged on the grippers 46. In this embodiment, under the program control of the automatic tool magazine motor to complete the automatic rotation, the turntable is driven to rotate automatically to the position where the corresponding tool holder needs to be replaced. The up and down lifting shaft assembly is controlled by the program to move left and right to the corresponding tool changing position, and drives the spindle to descend to the appropriate tool holder position to realize automatic tool changing. After the tool changing is completed, the automatic tool magazine motor rotates and drives the tool magazine cover plate to rotate, sealing the entire tool magazine to prevent dust. When needed, it can be opened again for tool changing.

[0039] The working principle of this utility model is as follows: Using marble as the base and column effectively avoids the long-term machining accuracy drift caused by thermal deformation of traditional metal frames during processing, enabling long-term machining operation. Combined with a three-axis motion system consisting of an upper and lower lifting axis assembly 13, a front and rear translation axis assembly 15, and a left and right translation axis assembly 17, it can meet the machining requirements of micron-level precision parts. Specifically, the workpiece is fixed on the front and rear translation axis assembly 15. The system control panel 4 is electrically connected to the lifting motor 41, machining spindle 33, left and right translation motor 23, front and rear translation motor 28, automatic tool magazine motor 42, cutting fluid circulation pump 48, and chiller 9. By setting the machining parameters through the system control panel 4, the system can start automatic operation. The front and rear translation motor 28 drives the front and rear translation slide plate 25 to move on the front and rear translation guide rail 26. The lifting motor 41 and left and right translation motor 23 drive the machining spindle 33 to move up and down and left and right, thereby performing fine machining on the workpiece in three-axis motion directions. During the machining process, under the blowing action of the air universal tube 34 and the cutting fluid universal tube... The spraying of cutting fluid onto pipe 36 cleans and cools the milling cutter 35, preventing damage from overheating and ensuring machining accuracy. During different machining operations, the program automatically controls the automatic tool magazine motor 42 to rotate the tool magazine turntable 45, causing the required tool holder 47 to rotate to the changing position. The lifting shaft assembly 13 moves above the tool holder 47, and the machining spindle 33 descends for automatic tool changing. After tool changing, the system automatically calibrates at the automatic tool setter 16 to ensure machining accuracy. As the operation proceeds smoothly, the cutting fluid sprayed during the machining process flows back to the cutting fluid tank 51. After passing through multiple layers of filtration, including the first filter plate 49 and the second filter plate 50, the machining residue and cutting fluid are automatically separated. The separated cutting fluid automatically flows back to the corresponding cutting fluid circulation pump 48 in the cutting fluid tank 51. Under the automatic extraction of the cutting fluid circulation pump 48, the cutting fluid is reciprocated and recycled. The multi-layer filtration improves the recycling rate of the cutting fluid, thereby reducing the replacement frequency and lowering the operation and maintenance costs.
