Description

Technical Field

[0001] The present invention relates to the technical field of rotating shafts, and more specifically, to a five-axis turntable with an angle limiter. Background Art

[0002] As a very important carrier of machine tools, the five-axis rotary table has played a very great role; especially the five-axis rotary table, which can use the two control coordinates of the original machine tool to control the rotation and tilt of the five-axis rotary table, or directly use the CNC device of the five-axis rotary table to connect with the machine tool to complete the required work cycle; it can complete the processing of holes, slots, planes at any angle, as well as the processing of curves, cam impellers, and can achieve high precision. In addition, it can also be used for non-CNC drilling, boring, and milling machine tools, and can independently complete equal-angle and unequal-angle indexing processing.

[0003] The advantages of using five-axis rotary table processing are:

[0004] 1. Small size and high stability. Because the overall structure of the five-axis turntable is small, it can be assembled on CNC lathes of various specifications and models. The special shockproof design makes the operation more stable.

[0005] 2. It has good practicality. No matter what type and specification of the commonly used CNC lathe, it can be assembled and used at will. The five-axis turntable does not need other external points for assembly, nor does it need to pay too much attention to the assembly positioning points, etc. The processing accuracy can be improved according to the needs of users;

[0006] 3. The torque is large, and it can maintain accurate positioning and tightening. The five-axis turntable itself does not take up a lot of space, so if you need to change the position or replace the product during operation, there will be no inconvenience. Of course, its adaptability is also relatively good, and it can adapt to many different harsh environments.

[0007] The existing five-axis turntable, especially the cradle-type five-axis turntable, adopts two rotating feed axes, both of which can be continuously indexed, continuously fed and linked controlled; among them, the feed axis that can rotate arbitrarily within 360° is called the rotating axis, and the axis that can only rotate forward and backward within a certain angle is called the swing axis, which is generally ±120°; both the swing axis and the rotating axis need to be driven by a motor-driven worm gear transmission or a motor direct drive, and the rotation angle and stop position of the five-axis turntable are controlled by the signal of the encoder at the tail of the driving motor, including the angle soft limit in the system, which are all set in the machine control parameters. For example, patent CN17961581A discloses a five-axis turntable, which discloses that the A-axis spindle and the A positioning axis are rotatably connected through a fourth bearing, and a first grating encoder is provided on the A fixed cover plate. The first grating encoder can detect the actual rotation speed of the A-axis spindle and the position of the workbench, and feedback the numerical value. The grating encoder can determine the position and movement of the object.

[0008] However, once the encoder is damaged or the communication fails, the five-axis turntable will rotate uncontrollably. In particular, the axis responsible for driving the swing arm will cause a serious collision between the five-axis turntable and the main shaft of the machine tool once it rotates uncontrollably during the operation of the machine, which will not only damage the parts being processed, but may also cause the machine tool to collide with the machine. The cables inside the five-axis turntable are all twisted into a knot, causing them to break, causing leakage and serious damage to the machine tool, and splashing objects will also cause casualties. When the machine is not in the process of processing and operation, if the machine assembly or maintenance personnel only stop the swing arm rotation at this time, and then enter the working chamber to work, if the system control fails at this time, or the emergency stop switch is accidentally turned on, the five-axis turntable will rotate uncontrollably, which will cause very serious casualties. Based on the unreliable situation of electrical control, it is very necessary to design a mechanical forced stop limit switch for the drive shaft responsible for driving the swing arm. Whenever the limit is exceeded, the drive motor will be forcibly powered off. Summary of the invention
