Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a lifting type hollow rotating platform. Background Art

[0002] The hollow rotating platform is used in a variety of rotating motion occasions. It can replace the direct drive motor and cam divider. It combines high work efficiency, high precision, high rigidity, and high cost performance, and can strike a balance between the two. The repeated positioning accuracy is ≤ 5 seconds. The motor is easy to configure and the load is stable. It can be matched with AC servo motors or stepper motors to perform arbitrary angle division. It can meet the digital control that the divider cannot achieve, and the positioning accuracy is comparable to that of the direct drive motor, which can greatly reduce costs.

[0003] The existing hollow rotating platforms have certain defects when used. For example, a hollow rotating platform disclosed in the utility model patent with authorization announcement number CN 218452959 U is a prior art device. Although it can ensure that the rotating platform is evenly stressed and has high stability during lifting and processing, if the bottom plate of the device is not raised to the highest point, that is, the bottom plate is at a certain point in the middle of the lifting screw rods, then the top ends of multiple lifting screw rods are all located above the bottom plate. The part located above the bottom plate will bring inconvenience to the processing operation on the surface of the rotating platform. In addition, with the development of technology and the increase in demand, some processing techniques require the rotating platform to be tilted at a certain angle to facilitate the corresponding processing process, but the device can only maintain a horizontal position and cannot be tilted. To this end, we design a lifting hollow rotating platform to solve the above technical problems. Utility Model Content

In addition, the fastening bolts can be screwed to make the fastening bolts and the corresponding fixing holes cooperate and connect to fix the position of the lifting block, further improving the stability and facilitating the workpiece processing operation in this state. There will be no extra long installation columns above the lifting plate, that is, the top space of the hollow rotating platform is spacious and free of obstacles, which improves the convenience of processing; according to the process requirements, when the hollow rotating platform needs to be tilted at a certain angle, the first electric push rod and the second electric push rod can be started at the same time, and the second electric push rod drives the first electric push rod to move to the left through the connecting rod, the connecting plate and the slider. At the same time, the first electric push rod drives the right side of the lifting plate to tilt downward, so that the lifting plate can be tilted at a certain angle, even if the hollow rotating platform is tilted at a certain angle, so as to meet specific processing technology requirements and improve the applicability of the device. It is simple and convenient to operate and is worthy of promotion. BRIEF DESCRIPTION OF THE DRAWINGS
