Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a CNC five-axis linkage grinding machine. Background Technology

[0002] A CNC grinding machine is a modern industrial device that uses computer numerical control technology to automate and precisely grind, polish, and deburr workpiece surfaces. It represents an upgrade from traditional grinding processes, aiming to improve efficiency, stabilize quality, and reduce labor costs. A CNC grinding machine typically includes a three-axis (X, Y, Z) linear motion module (usually using high-precision lead screws or linear motors) to control the precise movement of the grinding tool in three-dimensional space.

[0003] Existing CNC grinding machines have low mobility and can only grind three sides of a workpiece in a single clamping. When grinding complex spatial curved surfaces and irregularly shaped parts, the grinding efficiency of the device is extremely low, which is difficult to meet the needs of industrial production. Utility Model Content

[0004] The purpose of this utility model is to propose a CNC five-axis linkage grinding machine to solve the problem of low mobility in CNC grinding machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A CNC five-axis linkage grinding machine includes a base and a gantry frame. A support frame is slidably mounted on the base. A moving component for driving the support frame to move back and forth is provided on the base. A fixed plate is fixedly mounted on the support frame. A support plate is provided on the gantry frame. A fixed seat is slidably mounted on the support plate. A flexible grinding head is mounted on the lower end of the fixed seat. A moving component for driving the flexible grinding head to perform multi-dimensional movements is provided on the gantry frame.

[0006] As a further description of the above technical solution: the moving component includes a lead screw fixedly mounted on the output shaft of a first motor, the first motor being fixedly mounted on a base, the lead screw being rotatably connected to the base, and the lead screw being threadedly connected to a support frame.

[0007] As a further description of the above technical solution: a guide rail is fixedly installed on the base, and the support frame is slidably connected to the guide rail.

[0008] As a further description of the above technical solution: the movable component includes a first gear fixedly mounted on the output shaft of the second motor, a second gear fixedly mounted on the output shaft of the third motor, an AC swing head rotatably mounted on the lower end of the fixed seat, and a first rack and a second rack respectively fixedly mounted on one side of the gantry and the fixed seat. The second motor and the third motor are both fixedly mounted on the support plate. The flexible grinding head is rotatably mounted on the movable shaft of the AC swing head, wherein the first gear meshes with the first rack, and the second gear meshes with the second rack.

[0009] As a further description of the above technical solution: a first slide rail is fixedly installed on the gantry frame, and a second slide rail is fixedly installed on one side of the fixed seat. Both the first slide rail and the second slide rail are slidably connected to the bearing plate.

[0010] As a further description of the above technical solution: a chip removal funnel is fixedly installed inside the base, and a dust collection basin is slidably installed at the lower end of the base, with the dust collection basin located directly below the chip removal funnel.

[0011] As a further description of the above technical solution: a fixed frame is fixedly installed on the gantry frame, and an operating platform is fixedly installed on the fixed frame.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: The moving component drives the support frame and the fixed plate to move back and forth, adjusting the position of the workpiece. The movable component can drive the flexible grinding head to move left and right, up and down, and can also drive the flexible grinding head to rotate 360° axially in two directions. Combined with the back and forth movement of the support frame, five-axis linkage is achieved. The workpiece can be clamped and processed on five sides at once. When grinding complex spatial curved surfaces and irregularly shaped parts, the number of times the device needs to change the clamping of the workpiece can be greatly reduced. The device has high grinding efficiency and meets the needs of industrial production. During the workpiece grinding process, a large amount of debris is generated. Some of the debris falls directly into the chip removal funnel and then slides down into the dust collection basin. Some debris stays on the fixed plate. After the workpiece is processed, the operator uses a cleaning tool to sweep this debris into the chip removal funnel and then into the dust collection basin to collect the debris, ensuring the cleanliness of the surrounding environment of the device and preventing dust from affecting the health of the operators. When a large amount of debris accumulates in the dust collection basin, the dust collection basin is directly pulled out for centralized collection and treatment. Attached Figure Description

A moving component for driving the flexible grinding head 16 to perform multi-dimensional movements is provided on the gantry frame 13. The workpiece to be polished is fixed on the fixed plate 12. The moving component drives the support frame 11 and the fixed plate 12 to move back and forth to adjust the position of the workpiece. The movable component can drive the flexible polishing head 16 to move left and right and up and down. It can also drive the flexible polishing head 16 to rotate 360° axially in two directions. With the back and forth movement of the support frame 11, five-axis linkage is realized. The workpiece can be clamped and processed on five sides at once. When polishing complex spatial curved surfaces and irregular parts, the number of times the device needs to change the clamping of the workpiece can be greatly reduced. The device has high polishing efficiency and meets the needs of industrial production. The moving component includes a lead screw 21 fixedly mounted on the output shaft of the first motor 2. The first motor 2 is fixedly mounted on the base 1. The lead screw 21 is rotatably connected to the base 1. The lead screw 21 is threadedly connected to the support frame 11. A guide rail 3 is fixedly mounted on the base 1. The support frame 11 is slidably connected to the guide rail 3. The first motor 2 drives the lead screw 21 to rotate, and the lead screw 21 slides along the guide rail 3, allowing the support frame 11 and the fixed plate 12 to move back and forth, adjust the position of the workpiece, and cooperate with the flexible grinding head 16 to perform grinding work.

A first slide rail 5 is fixedly mounted on the gantry frame 13, and a second slide rail 51 is fixedly mounted on one side of the fixed base 15. Both the first slide rail 5 and the second slide rail 51 are slidably connected to the support plate 14. The second motor 4 drives the first gear 41 to rotate.

The third motor 43 drives the second gear 44 to rotate. The first gear 41 meshes with the second rack 45 to move, thereby causing the support plate 14 to slide relative to the second slide rail 51, that is, the fixed seat 15 to slide relative to the support plate 14, allowing the flexible grinding head 16 to move up and down. The AC swing head 46 can rotate 360° axially at the lower end of the fixed seat 15. The flexible grinding head 16 can rotate 360° axially relative to the AC swing head 46.

During the workpiece grinding process, a large amount of debris is generated. Some of the debris will fall directly into the chip discharge funnel 6 and then slide down into the dust collection basin 61. Some debris will stay on the fixed plate 12. After the workpiece is processed, the operator uses a cleaning tool to sweep this debris into the chip discharge funnel 6 and then into the dust collection basin 61 to collect the debris, ensuring the cleanliness of the surrounding environment of the device and preventing dust from affecting the health of the operators. When a large amount of debris accumulates in the dust collection basin 61, the dust collection basin 61 is directly pulled out for centralized collection and treatment.
