Description

Technical Field

[0001] The invention belongs to the technical field of turning-milling compound five-axis turntable, and in particular relates to a turning-milling compound five-axis turntable. Background Art

[0002] During the turning and milling composite processing, the workpiece is fixed on a five-axis turntable. When turning, the turntable can drive the workpiece to rotate around one or more axes according to the processing requirements, and cooperate with the linear motion of the turning tool to complete the processing of rotating surfaces such as cylindrical surfaces and conical surfaces. During milling, the turntable can also accurately rotate the workpiece to a suitable angle in three-dimensional space according to a pre-set program, so that the milling cutter can cut different sides and curved surfaces of the workpiece. Through the coordinated movement between the axes, one-time overall processing of complex-shaped workpieces can be achieved, greatly improving the processing efficiency and processing accuracy. For example, a high-precision five-axis turning and milling turntable with anti-bias clamping proposed in patent announcement number CN221270409U can fix the turntable and the clamping plate, and can drive two sets of sliding blocks to move in opposite directions along the guide groove through a bidirectional screw rod, clamping the workpiece in the middle position of the clamping plate, ensuring the accuracy of clamping and preventing offset.

[0003] Abnormal vibration of the five-axis turntable during operation is a common problem that will affect the processing quality and equipment life. If the workpiece installed on the turntable is irregular in shape, the center of gravity deviates from the center of the turntable, or the fixture is not balanced during design or installation, centrifugal force will be generated during the rotation of the turntable, causing vibration. For example, if a shaft workpiece with one end thick and the other end thin is processed without balancing, it is easy to have obvious vibration when rotating at high speed. In addition, the transmission mechanism of the turntable (such as belts, chains, couplings, etc.) is not firmly connected, and looseness and slippage will occur during operation, resulting in unstable power transmission, which in turn causes vibration. For example, if the belt is too loose, when the motor drives the turntable to rotate, the belt cannot effectively transmit power to the turntable, causing the turntable speed to be unstable and vibrate.

[0004] The five-axis rotary table vibrates abnormally during operation. The vibration will cause small and irregular changes in the relative position between the tool and the workpiece. In turning processing, it may cause deviations in the diameter, length and other dimensions of shaft workpieces. In milling processing, it will affect the diameter, depth and contour accuracy of the hole on the workpiece. For example, the original hole with a diameter of 50mm was to be processed. Due to vibration, the tool occasionally deviates from the predetermined position during the cutting process. The final processed hole diameter may fluctuate between 49.8mm and 50.2mm, and the precise design size requirements cannot be met. For workpieces with complex shapes, such as parts with curved surfaces or special-shaped structures, abnormal vibrations will destroy the stability of the tool in cutting along the predetermined trajectory, which may result in problems such as uneven curved surfaces and deformation of special-shaped structures. When the five-axis rotary table vibrates abnormally, the operator cannot level the center in the first time, which leads to a decrease in the processing accuracy of the workpiece.

[0005] Therefore, a turning-milling composite five-axis rotary table is proposed to solve the above problems. Summary of the invention

The side wall of the prompt tube 32 is fixedly connected to an air pressure tube 36 located between the sealing plate 34 and the blocking plate 35, and a fourth one-way valve 37 is provided in the air pressure tube 36.

After the five-axis turntable is installed, the height of the five-axis turntable can be adjusted according to the usage. By adjusting the height of the five-axis turntable, the center height can be matched with the center height of the workpiece. In this way, during processing, the tool can contact the workpiece at a more suitable angle and position, which is convenient for precise cutting. For example, when processing a higher shaft workpiece, raising the turntable height can ensure that the turning tool always accurately cuts along the generatrix of the workpiece during the turning process, avoiding the tool cutting position deviation due to height mismatch, which affects the processing accuracy.

[0038] A transverse plate 56 is fixedly connected to the inner wall of the cylinder 43, and a vertical groove matching the transverse plate 56 is formed on the rod wall of the second threaded rod 45. The cooperation between the transverse plate 56 and the vertical groove can prevent the second threaded rod 45 from rotating, so that the second threaded rod 45 can only rotate in the horizontal direction.

[0039] The operating principle of the present invention is now explained as follows: when the five-axis turntable vibrates abnormally during operation, the turntable frame 3 will drive the outer ball 7 and the inner ball 8 to vibrate together, while the vibrating ball 9 will not vibrate synchronously with the inner ball 8 due to inertia. Therefore, the vibrating ball 9 will squeeze the compressed airbag 11 during the vibration process, causing the gas pressure inside the compressed airbag 11 to increase. Under the action of air pressure, the gas inside the compressed airbag 11 will be transported to the space between the inner ball 8 and the outer ball 7 through the second one-way valve 14 and the air supply pipe 13, and will be transported to the detection box 15 through the curved pipe 16 and the third one-way valve 17. When the vibrating ball 9 drives the compressed airbag 11 to stretch, the air pressure inside the compressed airbag 11 will drop rapidly, thereby The external gas is transported to the compressed air bag 11 through the air intake pipe 10 and the first one-way valve 12 for storage. When the five-axis turntable continues to vibrate abnormally, more and more gas will be transported to the inside of the detection box 15. A part of the gas will be discharged through the microporous plate 23, and a large amount of gas will be squeezed to the piston plate 19, so that the piston plate 19 drives the conductive block 21 to move. The conductive block 21 will contact the resistor plate 22 during the movement. The conductive block 21 is electrically connected to the external power supply, and the end of the resistor plate 22 away from the conductive block 21 is electrically connected to the PLC controller 5. After the conductive block 21 contacts the resistor plate 22, an electrical signal will be transmitted to the PLC controller 5. After receiving the electrical signal, it is indicated that the five-axis turntable has abnormal vibration.

[0040] The PLC controller 5 will control the servo motor 27 to rotate in the forward direction, and the servo motor 27 will drive the first threaded rod 26 to rotate, and drive the first threaded cylinder 28 to move through the threaded fit, and the first threaded cylinder 28 drives the counterweight 30 to move through the guide plate 29, thereby changing the center position of the five-axis turntable. When the PLC controller 5 detects that the electrical signal from the resistor plate 22 becomes smaller, it means that the rotation direction of the servo motor 27 is correct. When the electrical signal becomes larger, it means that the rotation direction of the servo motor 27 is wrong. When the PLC controller 5 cannot detect the electrical signal from the resistor plate 22, it means that the five-axis turntable has been leveled.

[0041] When the PLC controller 5 detects the electrical signal from the resistor plate 22, it will control the electric push rod 33 to move back and forth. The electric push rod 33 will drive the sealing plate 34 to move up and down once. In the process of moving upward, the sealing plate 34 will compress the air above, so that the air above the sealing plate 34 will be transported to the top of the piston seat 38 through the single component on the surface of the blocking plate 35, so that the piston seat 38 moves upward to a certain position, and a small amount of air will be slowly discharged through the porous plate 39 (after one hour, the gas under the piston seat 38 will be completely discharged). When the sealing plate 34 moves downward, the external air will enter the prompt tube 32 through the air pressure tube 36 and the fourth one-way valve 37. When the PLC controller 5 detects the electrical signal from the resistor plate 22 many times, the piston seat 38 will move upward to squeeze the trigger switch 40, and the trigger switch 40 will control the buzzer 41 to work through the PLC controller 5, reminding the operator to inspect the five-axis turntable in time.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
