Description

Technical Field

[0001] The utility model relates to the field of loading mechanisms, and particularly to a loading mechanism for a five-axis grinding machine. Background Art

[0002] A five-axis grinding machine is a high-precision machining device that uses five coordinate axes (including three linear axes X, Y, Z and two rotational axes, usually axis A and axis C or axis B and axis C) to control the movement directions of the workbench and the tool, so as to achieve extremely complex and precise machining tasks. This grinding machine is widely used in industries such as aviation, aerospace, automotive, and medical, and can machine high-precision spherical surfaces, helical surfaces, complex curved surfaces, etc., as well as high-precision workpieces such as gears and threads. The five-axis grinding machine adopts an advanced numerical control system and controls the movement and working process of the grinding machine through programming instructions, and has the advantages of high efficiency, high precision, and fast machining speed, and can meet the increasingly complex and changeable machining requirements.

[0021] As Figure 2 shown in the figure, a set of front and rear symmetric support plates 5 are respectively fixedly installed on the top surfaces of the first conveyor belt 1 and the second conveyor belt 2, and a top plate 6 is jointly fixedly installed on the top surfaces of the front and rear symmetric support plates 5. A rotating hole 7 is opened on the side wall of the top plate 6. Through the rotating hole 7 opened on the side wall of the top plate 6 installed on the top surface of the support plate 5, the rotating rod 9 can rotate in the rotating hole 7;

[0022] As Figure 3 shown in the figure, rotating rods 9 are respectively fixedly installed at the left and right ends of the lead screw 8, and the rotating rods 9 are movably installed in the rotating holes 7. The driving motor 10 is fixedly installed on the outer side wall of the right top plate 6, and the output end of the driving motor 10 is fixedly installed together with the rotating rod 9 at the right end. A sliding rod 11 is also fixedly installed between the left and right symmetric top plates 6 and in front of the lead screw 8. When the driving motor 10 is started, the driving output end will drive the rotating rod 9 to rotate in the rotating hole 7, and the rotating rod 9 will drive the lead screw 8 to rotate. The provided sliding rod 11 is used to cooperate with the sliding table 12 and plays a role of moving limit and guiding for the sliding table 12;

[0023] As Figure 3As shown in the figure, a screw hole 13 is provided at the rear of the side wall of the sliding table 12 and is threadedly connected to the lead screw 8 through the screw hole 13. A sliding hole 14 is provided in front of the side wall of the sliding table 12 and is movably installed with the slide bar 11 through the sliding hole 14. A left side plate 15 is fixedly installed on the left side wall of the sliding table 12, and a right side plate 16 is also fixedly installed on the right side wall of the sliding table 12.

In this way, the workpiece to be processed can be moved above the processing table of the five-axis grinding machine, and the processed workpiece can be moved above the second conveyor belt 2. The provided left side plate 15 and right side plate 16 are respectively used to cooperate with the installation and use of the first cylinder 17 and the second cylinder 18;

First pneumatic grippers 20 are respectively fixedly installed on the front and rear side walls in the notch of the first concave seat 19. After the first cylinder 17 drives the output end to push the first concave seat 19 downward, the first pneumatic grippers 20 can clamp the workpiece to be processed on the blanking table 3, and after moving, the workpiece to be processed can be placed on the processing table in the five-axis grinding machine for processing to achieve the purpose of automatic feeding. Among them, the first pneumatic gripper 20 is a parallel pneumatic gripper;

[0025] As Figure 3 shown in the figure, an inverted second concave seat 21 is fixedly installed on the output end of the second cylinder 18, and second pneumatic grippers 22 are respectively fixedly installed on the front and rear sides of the inner wall of the notch of the second concave seat 21. After the second cylinder 18 drives the output end to push the second concave seat 21 downward, the processed workpiece on the processing table in the five-axis grinding machine will be clamped by the second pneumatic grippers 22, and after moving, the processed workpiece can be placed on the second conveyor belt 2 to achieve the purpose of automatic blanking. Among them, the second pneumatic gripper 22 is a parallel pneumatic gripper.

[0026] It should be noted that the present utility model is a loading mechanism for a five-axis grinding machine. When the first cylinder 17 and the second cylinder 18 installed on the top surfaces of the left side plate 15 and the right side plate 16 on the left and right sides of the slide table 12 are simultaneously opened, the second cylinder 18 will drive the output end to push the first concave seat 19 downward, and the first pneumatic gripper 20 installed on the front and rear sides of the inner wall of the notch of the first concave seat 19 will complete the clamping of the workpiece to be processed conveyed to the blanking table 3 through the first conveyor belt 1. After clamping, the output end of the first cylinder 17 will drive the first concave seat 19 to move upward. In this way, the workpiece to be processed clamped by the first pneumatic gripper 20 is removed from the blanking table 3, and the first conveyor belt 1 will run to convey the next workpiece to be processed back to the blanking table 3 to prepare for the next loading. At the same time, the second cylinder 18 will drive the output end to push the second concave seat 21 downward, and the second pneumatic gripper 22 installed on the front and rear side walls of the notch of the second concave seat 21 will complete the clamping of the workpiece after processing on the processing table in the five-axis grinding machine. After clamping, the output end of the second cylinder 18 will drive the second concave seat 21 to move upward. In this way, the workpiece after processing clamped by the second pneumatic gripper 22 is removed from the processing table. At this time, the drive motor 10 installed on the outer side wall of the right top plate 6 is turned on. The drive motor 10 will drive the output end to drive the rotating rods 9 at both ends of the lead screw 8 to rotate in the rotating holes 7 opened on the side wall of the top plate 6 on the top surfaces of the symmetric support plates 5. The rotating rod 9 will drive the lead screw 8 to rotate. The slide table 12 will move horizontally to the right along the lead screw 8 through the screw hole 13, and the slide table 12 will also slide along the slide rod 11 installed between the left and right symmetric top plates 6 through the slide hole 14 until the workpiece to be processed moves above the processing table and the workpiece after processing moves above the second conveyor belt 2. Then, the output ends of the first cylinder 17 and the second cylinder 18 respectively drive to push the first concave seat 19 and the second concave seat 21 downward, and after the first pneumatic gripper 20 and the second pneumatic gripper 22 stop clamping the workpieces, the workpiece to be processed can be placed on the processing table in the five-axis grinding machine, and the workpiece after processing can be placed on the second conveyor belt 2 and conveyed away. Finally, the slide table 12 is moved to the left to make the first pneumatic gripper 20 and the second pneumatic gripper 22 respectively move above the blanking table 3 and the processing table in the five-axis grinding machine, so as to prepare for the next loading and unloading of the workpiece, enabling the five-axis grinding machine to have the function of automatic loading and unloading, replacing the manual method for loading and unloading, and enabling the loading and unloading operations to be carried out simultaneously. This not only reduces the labor intensity, saves time and effort, but also improves the processing efficiency.
