Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a rigidity-enhanced turntable structure device and a processing machine tool. Background Art

[0002] The turntable structure of machining tools plays a vital role in modern manufacturing, primarily used to improve machining efficiency and ensure precision. By upgrading machine tool capabilities to four- or five-axis machining, the turntable structure addresses the common issues of three-axis machining, such as low efficiency, multiple clamping requirements, and inability to ensure machining precision. The turntable structure, with its rotatable table, effectively clamps the workpiece and enables rotation and indexing. This feature is particularly evident in CNC machine tools. As one of the core functional components of a machine tool, the CNC turntable, when added to a machine tool, can upgrade a three-axis CNC machine tool to a four- or five-axis one, significantly improving machining efficiency. Especially in complex part machining scenarios, the CNC turntable, acting as the fourth or fifth axis, provides the necessary interlocking machining capabilities. It is worth noting that the cost of the turntable typically accounts for one-quarter to one-third of the total machine tool cost, so its quality and performance directly impact the overall machining quality and economic benefits.

[0003] In many processing fields, especially in machining, welding, and assembly processes, turntables serve as crucial support and rotational devices. Their stability and load-bearing capacity directly impact machining accuracy and overall equipment performance. With the increasing demands for industrial automation and precision machining, the market is placing higher demands on turntable performance. In practical applications, the rigidity of the turntable structure directly impacts machining accuracy and operational stability. However, in the process of enhancing turntable rigidity, ensuring both safety and stability remains a pressing technical challenge.

[0004] Traditional turntable structures often increase rigidity by increasing the thickness of the supporting structure or using higher-strength materials. However, this approach can increase the turntable's weight, burdening the drive system and potentially affecting its dynamic performance. Furthermore, excessively increasing the rigidity of certain components can lead to structural imbalances and reduce overall stability.

[0005] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0006] In the prior art, traditional turntable structural devices tend to increase the burden on the drive system when improving rigidity, and may also affect its dynamic performance and reduce overall stability. Existing turntable structural devices seek new solutions in the technology of improving rigidity. Therefore, the utility model provides a turntable structural device and a processing machine tool with enhanced rigidity to solve the above problems.

[0007] In the first aspect, the utility model provides a rigidity-enhanced turntable structure device, which includes a center turntable, a center rotating shaft, a hydraulic clamping device, a left support structure of the turntable and a right support structure of the turntable.

The hydraulic clamping device is set on the center turntable, and the hydraulic clamping device includes respectively symmetrical clamp supports and respectively symmetrical clamping arms. The clamping arms are connected to the clamp supports, and a hydraulic cylinder is set in the clamp support. The hydraulic cylinder controls the clamping arm to clamp the top clamp chassis during processing.

[0008] In one implementation, the height at which the central rotating shaft extends from the central rotating disk is the same as the height of the clamp support.

[0009] In one implementation, the clamp arm includes a fixing clamp and a pressing member movably connected to the fixing clamp, the fixing clamp and the pressing member include a clamping surface in contact with the clamped object, and a gasket is provided on the clamping surface.

[0010] In one implementation, the hydraulic cylinder includes a cylinder body, a piston, and a piston rod, and the clamp arm is connected to the piston rod.

[0011] In one implementation, the central shaft is connected to the left support structure of the turntable and the right support structure of the turntable respectively in a rotational connection.

[0012] In a second aspect, the present invention further provides a processing machine tool, which includes the rigidity-enhanced turntable structure device described in any one of the above items.

[0013] Beneficial effect: The utility model sets the hydraulic clamp device, so that when processing is required, the hydraulic clamp device clamps and fits together to form a whole, thereby enhancing the rigidity of the hydraulic clamp device; at the same time, it can cooperate with the central rotating shaft to fix the top clamp chassis to achieve precise positioning and clamping of the workpiece, providing a turntable structure device and processing machine tool with strong stability, strong rigidity, simple structure, modular design, small size, easy installation and disassembly, and easy maintenance, which can meet various occasions with high requirements on the stability and rigidity of the turntable structure device.

[0024] The utility model provides a rigidity-enhanced turntable structure device, which includes a center turntable 1, a center rotating shaft 2, a hydraulic clamping device 3, a left support structure 4 of the turntable and a right support structure 5 of the turntable. The center rotating shaft 2 is arranged through the center turntable 1, and the left and right sides of the center turntable 1 are fixedly connected to the left support structure 4 of the turntable and the right support structure 5 of the turntable respectively. The hydraulic clamping device 3 is arranged on the center turntable 1, and the hydraulic clamping device 3 includes respectively symmetrical clamp supports 31 and respectively symmetrical clamping arms 32. The clamping arms 32 are connected to the clamp supports 31, and a hydraulic cylinder is arranged in the clamp support 31. The hydraulic cylinder controls the clamping arms 32 to clamp the top clamp chassis 6 during processing.

[0025] Specifically, the clamp arm 32 includes a fixed clamp 321 and a pressure member 322 movably connected to the fixed clamp 321. The fixed clamp 321 and the pressure member 322 include clamping surfaces that contact the clamped object. Gaskets (not shown) are provided on the clamping surfaces to protect the workpiece surface. Furthermore, the hydraulic cylinder (not shown) includes a cylinder body, a piston, and a piston rod, and the clamp arm 32 is connected to the piston rod. The operation of the clamp arm 32 is controlled by a control system. When the turntable structure rotates, the clamp arm 32 is in a loose state. When the turntable structure is processing, the hydraulic cylinder pushes the clamping member 322 to contact and clamp the top clamp chassis 6 near both ends of the center turntable 1, so that the clamping surfaces of the fixed clamp 321 and the clamping member 322 contact and clamp the protrusions of the top clamp chassis. Continuous hydraulic pressure ensures that the clamp arm 32 remains in a closed state. At this time, the clamp arm 32 and the top clamp chassis 6 are fitted together to form a whole for processing. In some embodiments, the hydraulic clamp device 3 may also include a position sensor (not shown) for monitoring the opening and closing state of the clamp arm 32.

[0026] Specifically, the height at which the center shaft 2 extends out of the center turntable 1 is the same as the height of the fixture support 31, which is conducive to maintaining the balance and stability of the structure. Furthermore, the center shaft 2 is connected to the support structure 4 on the left side of the turntable and the support structure 5 on the right side of the turntable in a rotational connection. The center shaft 2 adopts a rotational connection method, which can be rotated more flexibly, thereby improving the operability and applicability of the turntable. Among them, the A-axis is a rotation axis, which makes the workpiece rotate around an axis perpendicular to the processing plane, and is often used to realize the processing of complex curved surfaces, such as cylinders, cones, etc. The C-axis is a rotary axis, which makes the workpiece rotate around an axis parallel to the processing plane, and is often used to realize the rotation positioning of the workpiece, such as multi-faceted processing and multi-angle processing. That is, the rotation around the X-axis is the A-axis, and the rotation around the Z-axis is the C-axis.

[0027] The utility model provides a hydraulic clamp device, so that when processing is required, the hydraulic clamp device can clamp and fit together to form a whole, thereby enhancing the rigidity of the hydraulic clamp device; at the same time, it can cooperate with the central rotating shaft to fix the top clamp chassis to achieve precise positioning and clamping of the workpiece, and provide a turntable structure device and processing machine tool with strong stability, strong rigidity, simple structure, modular design, small size, easy installation and disassembly, and easy maintenance, which can meet various occasions with high requirements on the stability and rigidity of the turntable structure device.
