Description

Technical Field

[0001] The utility model relates to the technical field of machining, and particularly relates to a turntable structure device with enhanced supporting force and a machining machine tool. Background Art

[0002] The turntable structure device of a machining machine tool plays an important role in modern manufacturing, mainly used to improve machining efficiency and ensure machining accuracy. By upgrading the machine tool function to four-axis or five-axis machining, the turntable structure solves the problems commonly existing in three-axis machining, such as low efficiency, the need for multiple clamping, and the inability to ensure machining accuracy. Through its rotatable tabletop, the turntable device can effectively clamp workpieces and achieve rotation and indexing positioning. This feature is particularly obvious in CNC machine tools. As one of the core functional components of the machine tool, the CNC turntable can upgrade a three-axis CNC machine tool to a four-axis or five-axis machine tool by being added to the machine tool, thus significantly improving machining efficiency. Especially in the scenario of machining complex parts, the CNC turntable, as the fourth axis or the fifth axis, provides the necessary simultaneous machining ability. It should be noted that the cost of the turntable usually accounts for 1 / 4 to 1 / 3 of the total cost of the whole machine tool, so its quality and performance directly affect the overall machining quality and economic benefits.

[0003] In many machining fields, especially in processes such as machining, welding, and assembly, the turntable, as an important supporting and rotating device, its stability and load-bearing capacity directly affect machining accuracy and the overall performance of the equipment.

[0022] Those skilled in the art of the present technology can understand that unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as the general understanding of those of ordinary skill in the art to which the present utility model belongs. It should also be understood that terms such as those defined in a general dictionary should be understood to have a meaning consistent with the meaning in the context of the prior art, and will not be interpreted with an idealized or overly formal meaning unless specifically defined as here.

[0023] Referring to Figures 1-3 , Figure 1 is the overall structural schematic diagram of the turntable structure device with enhanced supporting force provided by the present utility model, Figure 2 is Figure 1Front structural schematic diagram of the turntable structure device with enhanced supporting force shown Figure 3 is Figure 1 Exploded structural schematic diagram of the turntable structure device with enhanced supporting force shown. The present utility model provides a turntable structure device with enhanced supporting force, which includes a central turntable 1, a central rotating shaft 2, a hydraulic bottom supporting device 3, a left supporting structure 4 of the turntable, and a right supporting structure 5 of the turntable. The central rotating shaft 2 is arranged through the central turntable 1. The left and right sides of the central turntable 1 are respectively fixedly connected to the left supporting structure 4 and the right supporting structure 5 of the turntable. The hydraulic bottom supporting device 3 includes at least two hydraulic cylinders 6 symmetrically arranged along the central rotating shaft. The hydraulic cylinders 6 are used for locking when encountering resistance. The bottom supporting device 3 and the central rotating shaft 2 are used for jointly fixedly connecting to the top fixture chassis 7. Through the arrangement of the hydraulic bottom supporting device 3 of the present utility model, additional supporting force can be provided, enhancing the stability and load-bearing capacity of the turntable, and ensuring that the turntable will not tilt or shake due to force during the working process.

[0024] Specifically, the number of the hydraulic cylinders 6 is four, and the four hydraulic cylinders 6 are arranged in central symmetry along the central rotating shaft 2. The hydraulic cylinders 6 arranged in a central symmetry manner can provide supporting force evenly, so that the turntable structure device will not generate offset or imbalance when stressed. During use, the hydraulic cylinders 6 contract by 1 mm when the central rotating shaft 2 rotates, and the hydraulic cylinders 6 pop out and lock when encountering resistance. The hydraulic cylinders 6 can be locked when encountering resistance, maintaining the fixed position of the turntable and avoiding accidental movement or out-of-control during work. Specifically, when machining is required, such as drilling, the hydraulic cylinders 6 automatically jack up to provide strong support to support the central rotating shaft 2 for machining larger holes. The hydraulic cylinders 6 have a simple structure and reliable operation, and are widely used in the hydraulic system of machine tools.

[0025] Furthermore, the connection modes of the central rotating shaft 2 with the left supporting structure 4 and the right supporting structure 5 of the turntable are rotational connections. The central rotating shaft 2 adopts a rotational connection mode, which can rotate more flexibly, improving the operability and application range of the turntable. Furthermore, the range of the A axis of the central rotating shaft 2 is less than 60 degrees, and the range of the C axis is less than 80 degrees. Among them, the A axis is the rotation axis, which enables the workpiece to rotate around the axis perpendicular to the machining plane, and is commonly used to realize the machining of complex curved surfaces, such as cylinders and cones. The C axis is the rotation axis, which enables the workpiece to rotate around the axis of the machining plane, and is commonly used to realize the rotational positioning of the workpiece, such as multi-sided machining and multi-angle machining. That is, the rotation around the X axis is the A axis, and the rotation around the Z axis is the C axis.

[0026] In addition, in this embodiment, the central rotating shaft 2 is a micro bearing, and the inner diameter of the micro bearing is 1 mm. The setting of the small-diameter bearing of the central rotating shaft 2 makes the entire turntable structure device more compact and suitable for use in an environment with limited space.

[0027] By providing the hydraulic bottom support device, the present utility model can provide additional support force, which is used in cooperation with the central rotating shaft to jointly fixedly connect the top fixture chassis, enhancing the stability and support force of the turntable, ensuring that the turntable will not tilt or shake due to the applied force during operation, enabling a small central rotating shaft to withstand a large cutting force, and providing a turntable structure device and a processing machine tool with strong stability, large support force, simple structure, modular design, small volume, convenient installation and disassembly, and convenient maintenance, which can meet various occasions with high requirements for the stability and support force of the turntable structure device.

[0028] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
