Description

Technical Field

[0001] This application relates to the field of dual-station rotary tables, and more specifically, to a support structure for dual-station machining on machine tools. Background Technology

[0002] Dual-station machining is designed to increase processing speed by setting up two stations for placing workpieces to be processed. While the workpiece is being processed at one station, the workpiece is replaced at the other station.

[0003] A related technical solution can be found in patent application number 202410263924.4, which discloses a method of setting two workstations on a carrier and placing a partition between the two workstations to prevent parts from splashing. However, with two workstations on a fixed carrier and the workpiece processing at one workstation and the workpiece replacement at the other workstation occurring simultaneously, the vibration generated during workpiece processing at one workstation is easily transmitted to the other workstation. Therefore, when workers change workpieces, the vibrating workstation is not conducive to the accurate installation of the workpiece onto the fixture. Utility Model Content

[0029] Reference Figure 1-4 ,

[0030] A support structure for dual-station machining on a machine tool includes a rotary table 1 and a rotary drive component. The rotary table 1 is used to mount a fixture for holding the workpiece to be machined. The rotary drive component has a rotating end connected to the rotary table 1. The drive component is a drive motor, and the rotating end is the output shaft of the drive motor, which directly drives the rotary table 1 to rotate. Two sets of fixtures are mounted on the rotary table 1. After the workpiece to be machined in one fixture is completed, the drive component drives the rotary table 1 to rotate, moving the other fixture to a machining position for further machining. The machined workpiece is then rotated to a position where it can be replaced. This significantly improves the machining speed. The rotary table 1 includes a connecting part 11 and a rotating support part 12. The connecting part 11 is connected to the rotating end, and both the connecting part 11 and the rotating support part 12 are block structures constituting the rotary table 1. A vibration damping gap is provided between the rotating support part 12 and the connecting part 11, and a vibration damping element is installed in the vibration damping gap.

[0031] One solution for the shock absorber is to use a pad with shock absorption function, such as a rubber pad. The shock absorption gap is a gap formed when the connecting part 11 and the rotating support part 12 are integrally formed. Therefore, embedding the pad with shock absorption function into the shock absorption gap can play a role in shock absorption.

[0032] Another embodiment of the shock absorber includes: multiple rigid rods 2 for connecting the connecting portion 11 and the rotating support portion 12, and a damping pad 3. The rigid rods 2 are used to maintain the connection portion 11 and the rotating support portion 12 in place, allowing the drive member to rotate the rotating support portion 12 via the connecting portion 11. The damping pad 3 is filled between the connecting portion 11 and the rotating support portion 12 to absorb vibrations between them. In this case, the damping gap is the gap formed due to the separation of the connecting portion 11 and the rotating support portion 12.

[0033] Specifically, a liquid storage chamber is formed in the shock-absorbing pad 3; the liquid storage chamber stores liquid. The liquid is preferably water. The presence of water in the shock-absorbing pad 3 allows for shock absorption, thereby improving the shock absorption effect between the connecting part 11 and the rotating support part 12, and better preventing vibration of the rotating support part 12 located at the material picking position. Therefore, it helps to improve the safety when changing workpieces.

[0034] Specifically, the shock absorber further includes a limiting ring disposed between the connecting portion 11 and the rotating support portion 12; the limiting ring wraps around the shock-absorbing pad 3. A portion of the limiting ring is connected to the connecting portion 11, and the other portion is connected to the rotating support portion 12. The purpose of the limiting ring wrapping around the shock-absorbing pad 3 is to prevent the shock-absorbing pad 3 from deforming towards the outside of the connecting portion 11 and the rotating support portion 12, thus better ensuring that the liquid storage chamber in the shock-absorbing pad 3 has sufficient pressure to fill and press firmly between the connecting portion 11 and the rotating support portion 12, thereby better ensuring the shock absorption effect.

[0035] In some embodiments, the supporting structure further includes a support platform 4; a universal ball 5 is provided below the rotating support 12, and the universal ball 5 abuts against the surface of the support platform 4. The universal ball 5 and the support platform 4 are provided to provide upward support for the rotating support 12, so that the rigid rod 2 provides external force for the rotating support 12 to rotate only between the rotating support 12 and the connecting part 11, preventing the rigid rod 2 from bending and deforming downwards after long-term use, and better ensuring the accuracy and stability of the overall machine tool in processing workpieces.

[0036] Specifically, a guide groove 41 is formed on the support platform 4, and the universal ball 5 is at least partially fitted into the guide groove 41. The guide groove 41 is designed to guide the universal ball 5. In subsequent processing, only the precision machining of the guide groove 41 needs to be ensured, without the need to perform precision machining on the entire platform surface of the support platform 4, which helps to reduce costs.

[0037] In some embodiments, a first connecting plate 6 and a second connecting plate 7 are respectively provided at both ends of the shock-absorbing pad 3. The first connecting plate 6 is connected to the connecting portion 11, and the second connecting plate 7 is connected to the rotating support portion 12. The first connecting plate 6 and the second connecting plate 7 are provided to facilitate the installation of the shock-absorbing pad 3 between the connecting portion 11 and the rotating support portion 12.

[0038] Specifically, the first connecting plate 6 has a plurality of first protrusions 61 on its end face near the connecting portion 11; the second connecting plate 7 has a plurality of second protrusions 71 on its end face near the rotating support portion 12. By using the first protrusions 61 to abut against the end face of the connecting portion 11 and the second protrusions 71 to abut against the end face of the rotating support portion 12, only certain portions of the first connecting plate 6 and the second connecting plate 7 need to be precision-machined, which helps to reduce costs.

[0039] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
