Embodiment 1

[0057] A fulcrum dynamic combined parallel mechanism for realizing high-precision positioning of a circular track platform, such as figure 1 shown, including figure 2 The horizontal position and posture adjustment device 3 and the coaxiality flexible clamping adjustment device are shown;

[0058] The horizontal position and attitude adjusting device 3 includes two SPS adjusting branches 32 and one PRR adjusting branch 31 located below the circular track 1 and distributed around the circumference of the circular track 1, and the above three adjusting branches form a set of 1T2R parallel mechanism, By adjusting the length of the branch chain, the level of the circular track can be positioned with high precision;

[0059] SPS modulates branch 32 as Figure 4 As shown, including the fast hand clamp (SPS, including the fast hand clamp handle (SPS) 321 and the fast hand clamp base (SPS) 322), the upper ball hinge 323, the upper spin rod ( SPS) 324, Intermediate Spinning Rod (SPS...

Embodiment 2

[0073] A fulcrum dynamic combination parallel mechanism for realizing high-precision positioning of a circular orbit platform, its structure is basically the same as that of Embodiment 1, the difference is that its horizontality posture adjustment device is three SPS adjustment branch chains.

Abstract

The invention discloses a fulcrum dynamic combined parallel mechanism for realizing high-precision positioning of a circular track platform, which comprises a coaxiality flexible clamping adjustment device constituting a plane parallel adjustment mechanism and a horizontality posture adjustment device constituting a 1T2R parallel mechanism; The coaxiality flexible clamping adjustment device is in flexible contact with the cylinder wall, and the flexible top plate presses the cylinder wall to form a multi-contact fulcrum. The gap of the tooth segment is fine-tuned to realize the adjustment of the coaxiality and roundness of the track. By adjusting the length of the adjustment branch of the levelness posture adjustment device, the levelness of the ring track can be positioned with high precision. The fixed fulcrum of the track level adjustment can be arbitrarily adjusted. The invention has the advantages of high adjustment precision for the levelness / coaxiality of the circular track, high speed, convenient and quick operation, time saving and labor saving, and good application prospect.

Description

technical field [0001] The invention belongs to the technical field of equipment platform adjustment, and relates to a fulcrum dynamic combination parallel mechanism for realizing high-precision positioning of a circular track platform, in particular to an adjustment mechanism for realizing high-precision positioning of a large-scale circular track platform based on the parallel mechanism. Background technique [0002] Mechanical equipment, especially container equipment, is widely used in petroleum, chemical, steel, pharmaceutical, food and other industries. In the above application scenarios, because it needs to withstand high pressure of high temperature, low temperature, flammable, explosive, highly toxic or corrosive media, once an explosion or leakage occurs, catastrophic accidents such as fire and poisoning often occur, which will cause social economic and loss and harm to people's lives. [0003] In view of this, there are strict regulations and requirements for the...
