Description

Technical Field

[0001] This invention relates to the field of surface treatment technology for die-cast parts, specifically to a five-axis multi-station intelligent deburring machine. Background Technology

[0002] Die casting is a process in which molten metals such as copper, zinc, aluminum, or aluminum alloys are poured into a die casting machine equipped with a casting mold.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] like Figures 1 to 7As shown, this invention discloses a five-axis multi-station intelligent deburring machine, including a base 1, a workpiece seat 2 inside the base 1, a machining surface 21 on the workpiece seat 2, and a rotatable tooling fixture 3 on the machining surface 21. Multiple tooling fixtures 3 are spaced apart from each other. Below the workpiece seat 2 is a workpiece seat 2x-axis moving device for moving the workpiece seat 2 back and forth. Above the workpiece seat 2 is a rotatable tool holder 4, with a tool module 5 corresponding to the tooling fixture 3. The tool module 5 includes four different types of tools, each mounted on the four sides of the tool holder 4. Rotation of the tool holder 4 drives the tool module 5 to rotate around the y-axis, thus enabling switching between tools while simultaneously adjusting the tools in each tool module 5. The angle between the workpieces held by the tooling fixture 3 is such that the tool holder 4 is provided with a Z-axis moving device on one side to drive the tool holder 4 to move vertically, and a Y-axis moving device on the other side to drive the tool holder 4 to move left and right. When the workpiece is surface-machined, each workpiece can be clamped and fixed by its respective tooling fixture 3. The workpiece is moved back and forth by the X-axis moving device of the workpiece holder 2, and the tool module 5 is moved vertically and left and right by the Z-axis moving device and the Y-axis moving device of the tool holder 4, respectively. By rotating the tool holder 4 and the tooling fixture 3, five-axis machining can be performed on the workpiece, thereby realizing the synchronous machining of multiple surfaces of multiple workpieces and improving the overall machining efficiency.

[0027] In this embodiment, the workpiece seat 2 x-axis moving device includes two symmetrical first support platforms 61, and two opposing second support platforms 62 on both sides of the first support platforms 61. Both the first support platforms 61 and the second support platforms 62 are fixed to the bottom inner side of the machine base 1. The tops of both the first support platforms 61 and the second support platforms 62 are equipped with workpiece seat x-axis moving slide rails 63. The arrangement of multiple first support platforms 61 and second support platforms 62 provides multi-point support for the workpiece seat 2, improving the stability of the workpiece seat 2 during movement. A rotatable workpiece seat x-axis moving screw 64 is provided between the two first support platforms 61. The two ends of the workpiece seat x-axis moving screw 64 are rotatably connected by bearing seats. A workpiece seat x-axis moving guide block is provided at the bottom of the workpiece seat 2. 65. The workpiece seat x-axis moving guide block 65 is fitted onto the workpiece seat x-axis moving screw 64, forming a threaded engagement between the two. The bottom of the workpiece seat 2 is provided with a workpiece seat x-axis moving slider 66, which is coupled to the workpiece seat x-axis moving slide rail 63, forming a sliding engagement between the two. By driving the workpiece seat x-axis moving screw 64 to rotate through the corresponding motor, the workpiece seat 2, which is fitted onto the outer periphery of the workpiece seat x-axis moving screw 64 through the workpiece seat x-axis moving guide block 65, can move along the direction of the workpiece seat x-axis moving screw 64 under the guidance of the workpiece seat x-axis moving slider 66 and the workpiece seat x-axis moving slide rail 63. In this way, the workpiece held by the tooling fixture 3 can be moved back and forth.

[0028] In this embodiment, the tool holder 4y-axis moving device includes a beam frame 71 installed inside the machine base 1. The beam frame 71 is provided with two symmetrically arranged tool holder y-axis moving slide rails 72. A rotatable tool holder y-axis moving lead screw 73 is provided between the two tool holder y-axis moving slide rails 72. The two ends of the tool holder y-axis moving lead screw 73 are rotatably connected by bearing seats. A tool holder y-axis moving connecting seat 74 is provided on one side of the beam frame 71. A tool holder y-axis moving slider 75 and a tool holder 4y-axis moving guide block are provided on one side of the tool holder y-axis moving connecting seat 74. The tool holder y-axis moving slider 75 is fitted onto the tool holder y-axis moving guide block. The outer periphery of the movable lead screw 73 can form a threaded engagement between the two. The tool holder y-axis moving slider 75 is coupled to the tool holder y-axis moving slide rail 72 and can form a sliding engagement between the two. By driving the tool holder y-axis moving lead screw 73 to rotate through the corresponding motor, the tool holder 4, which is mounted on the outer periphery of the tool holder y-axis moving guide block through the tool holder 4 y-axis moving guide block, can move along the direction of the tool holder y-axis moving lead screw 73 under the guidance of the tool holder y-axis moving slider 75 and the tool holder y-axis moving slide rail 72. In this way, the tool module 5 can be moved left and right.

[0029] In addition, the tool holder 4 Z-axis moving device includes a tool holder Z-axis moving connecting seat 81, a tool holder Y-axis moving connecting seat 74 located on the side opposite to the beam frame 71 with symmetrically arranged tool holder Z-axis moving slide rails 82, a rotatable tool holder Z-axis moving lead screw 83 between the two tool holder Z-axis moving slide rails 82, the two ends of the tool holder Z-axis moving lead screw 83 being rotatably connected to the tool holder Y-axis moving connecting seat 74 through bearing seats, and a tool holder Z-axis moving slider 84 and a tool holder 4 Z-axis moving guide block located on the side of the tool holder Z-axis moving connecting seat 81 facing the tool holder Y-axis moving connecting seat 74. Coupled with the tool holder z-axis moving slide rail 82, and forming a sliding fit between the two, the tool holder 4 z-axis moving guide block is fitted around the tool holder z-axis moving screw 83, and forming a threaded fit between the two. By driving the tool holder z-axis moving screw 83 to rotate through the corresponding motor, the tool holder 4, which is fitted around the tool holder z-axis moving screw 83 through the tool holder 4 z-axis moving guide block, can move along the direction of the tool holder z-axis moving screw 83 under the guidance of the tool holder z-axis moving slider 84 and the tool holder z-axis moving slide rail 82, thus driving the tool module 5 to move up and down.

[0030] In this embodiment, a connecting arm 811 is provided on the side of the tool holder z-axis moving connecting seat 81 facing away from the tool holder y-axis moving connecting seat 74. One end of the connecting arm 811 extends outward to facilitate connection with the tool holder 4. Both ends of the tool holder 4 are rotatably connected to the connecting arms 811 on both sides through bearings. Each tool module 5 is spaced apart from each other along the length direction of the tool holder 4. The surface of the tool holder 4 is provided with a mounting port 41 for mounting tools. The tool body is fixed to the tool holder 4 by inserting the tool into the mounting port 41 and then connecting it with a thread. The tool holder 4 is provided with clearance ports 42 spaced apart from each other along the length direction. The clearance ports 42 make it easy to reach into the tool holder 4, thereby improving the convenience of tool assembly. In addition, one side of the connecting arm 811 is provided with a motor connected to one side end of the tool holder 4. The tool holder 4 can be driven to rotate by the corresponding motor.

[0031] In this embodiment, an inclined chip removal sidewall 101 is provided on the inner bottom of the machine base 1. The height of the chip removal sidewall 101 decreases sequentially from front to back to form an inclined surface. The machine base 1 is provided with a chip removal port 102 communicating with one side of the inclined surface. The bottoms of the first support platform 61 and the second support platform 62 are both in contact with the inclined surface. The second support platform 62 is provided with a material passage port 621. When the workpiece is surface-processed, the generated chips can fall into the bottom of the machine base 1. Under the action of the inclined surface, the chips can slide towards the chip removal port 102 by gravity, so as to facilitate the discharge of chips in the machine base 1. Furthermore, the material passage port 621 on the second support platform 62 can facilitate the sweeping of chips close to the second support platform 62 into the direction close to the first support platform 61 through the material passage port 621, so that the chips can slide towards the chip removal port 102 by gravity, thereby improving the convenience of chip discharge from various parts of the bottom of the machine base 1.

[0032] In this embodiment, there is an inclination angle between the machining surface 21 and the horizontal plane, so that the chips generated during machining will automatically slide off under the action of gravity, avoiding accumulation on the workpiece or the machining surface 21. This not only improves the surface machining quality but also reduces subsequent cleaning work. Furthermore, since die castings often have complex structures such as curved surfaces and grooves, by setting the machining surface 21 at an inclination angle, the surface to be machined 21 can be adjusted to the most advantageous position, so that multiple surfaces can be machined in one clamping, thereby improving machining efficiency.

[0033] In addition, a turntable 9 is provided on the machining surface 21. The top of the turntable 9 is used to connect the tooling fixture 3. The bottom of the turntable 9 is provided with a reducer 10 and a drive motor 11. The bottom of the turntable 9 is connected to the output end of the reducer 10 through a flange. The drive motor 11 is connected to the input end of the reducer 10. All drive motors 11 are connected in series, so that each turntable 9 can be driven to rotate synchronously. Furthermore, an assembly port 22 is provided on the opposite side of the workpiece seat 2 located on the machining surface 21. The assembly port 22 is provided to facilitate the insertion of a hand into the workpiece seat 2, thereby facilitating the assembly between the turntable 9, the reducer 10 and the drive motor 11.

[0034] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
