[0025] The following is combined with Figure 1-4 This application is described in further detail.
[0026] The embodiment of the present application discloses a limit adjustment mechanism for a large-size precision motion platform.
[0027] Reference Figure 1 and Figure 2 A limit adjustment mechanism for a large-size precision motion platform includes a steel frame 1, a vibration isolator 2 and a marble table 3. The steel frame 1 is horizontally arranged, the vibration isolator 2 is fixedly installed on the upper surface of the steel frame 1, the number of the vibration isolators 2 is six, and the six vibration isolators 2 are spaced and relatively arranged on the upper surface of the steel frame 1. The marble table 3 is horizontally arranged above the vibration isolator 2. The upper surface of the steel frame 1 is also spaced with a first limit mechanism 4, a second limit mechanism 5, a third limit mechanism 6 and a fourth limit mechanism 7. The steel frame 1 is fixedly connected to the marble table 3 through the first limit mechanism 4, the second limit mechanism 5, the third limit mechanism 6 and the fourth limit mechanism 7, so that the interval between the steel frame 1 and the marble table 3 is not less than the height of the vibration isolator 2, thereby protecting the vibration isolator 2 and reducing the vibration isolator 2 from being squeezed by the steel frame 1 and the marble during transportation.
[0028] Reference Figure 2 and Figure 3The first limiting mechanism 4, the second limiting mechanism 5, the third limiting mechanism 6 and the fourth limiting mechanism 7 have the same structure and are arranged at intervals between the vibration isolators 2. The first limiting mechanism 4, the second limiting mechanism 5, the third limiting mechanism 6 and the fourth limiting mechanism 7 all include a lower seat 8 and an upper seat 10. The upper seat 10 is located on the upper side of the lower seat 8. The lower seat 8 is threadedly connected with four lower seat locking screws 9. The four lower seat locking screws 9 are located at the four end corners of the lower seat 8, and the lower seat 8 is fixed to the steel frame 1 by the lower seat locking screws 9.
[0029] Reference Figure 1 and Figure 3 Four upper seat locking screws 11 are vertically installed on the upper seat 10, and the four upper seat locking screws 11 are located at the four end corners of the upper seat 10. The upper seat 10 is locked and fixed to the side of the marble table 3 close to the steel frame 1 by the upper seat locking screws 11. The side of the lower seat 8 close to the upper seat 10 is also threadedly connected with a fixing bolt 12. The axis of the fixing bolt 12 is perpendicular to the lower seat 8. The fixing bolt 12 fixes the upper seat 10 and the lower seat 8, so that the distance between the upper seat 10 and the steel frame 1 is greater than the height of the vibration isolator 2, thereby protecting the vibration isolator 2.
[0030] Reference Figure 4 In order to reduce the situation where the marble table 3 deviates in a certain direction during use, the lower seat 8 is also threadedly connected with a first left-right adjusting bolt 13 and a second adjusting bolt. The first left-right adjusting bolt 13 and the second adjusting bolt are horizontally and relatively arranged, and the axes of the two are located in the same straight line. When the marble table 3 is adjusted in the left and right directions, the vibration isolator 2 is in a ventilated state, and the left-right adjusting bolts on the first limit mechanism 4 and the second limit mechanism 5 are adjusted at the same time, or the left-right adjusting bolts on the third limit mechanism 6 and the fourth limit mechanism 7 are adjusted at the same time. During the adjustment process, a ruler is used to lean against the side of the marble table 3 and the side of the steel frame 1 to make the two flush.
[0031] The lower seat 8 is also threadedly connected with a front and rear adjusting bolt 14, which is horizontally arranged, and the axis of the front and rear adjusting bolt 14 is perpendicular to the axis of the left and right adjusting bolts. When the marble table 3 is adjusted in the front and rear directions, the vibration isolator 2 is in a ventilated state, and the front and rear adjusting bolts 14 on the first limiting mechanism 4 and the fourth limiting mechanism 7 are adjusted at the same time, or the front and rear adjusting bolts 14 on the second limiting mechanism 5 and the third limiting mechanism 6 are adjusted at the same time. During the adjustment process, a ruler is used to lean against the side of the marble table 3 and the side of the steel frame 1 to make the two flush.
[0032] The implementation principle of a large-size precision motion platform limit adjustment mechanism in the embodiment of the present application is:
[0033] Before transportation, the upper seat 10 needs to be fixed on the marble table 3, and the lower seat 8 needs to be fixed on the steel frame 1. Then the air source of the vibration isolator 2 is turned off, and the marble table 3 slowly falls until the upper seat 10 and the lower seat 8 are completely fitted together. Then, the upper seat 10 and the lower seat 8 are locked by the fixing bolts 12. During transportation, the vibration isolator 2 will not be subjected to the interaction force between the steel frame 1 and the marble table 3, which plays a role in protecting the vibration isolator 2 and facilitates transportation.
[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
