[0020] Furthermore, the lifting cylinder 1 13, the lifting cylinder 2 17, the lifting cylinder 3 21, and the lifting cylinder 4 25 all include an inner cylinder and an outer cylinder.

[0021] Further, the lifting seat 11 is threadedly connected to the threaded shaft 6, the lifting seat 2 15 is threadedly connected to the inner tube of the lifting cylinder 13, the lifting seat 3 19 is threadedly connected to the inner tube of the lifting cylinder 2 17, the lifting seat 4 23 is threadedly connected to the inner tube of the lifting cylinder 3 21, and the lifting seat 5 26 is threadedly connected to the inner tube of the lifting cylinder 4 25.

[0022] Furthermore, a positioning seat 10 and a push plate 1 are arranged between the lifting seat 1 and the column, a positioning seat 2 14 and a push plate 2 16 are arranged between the lifting seat 2 and the outer tube of the lifting cylinder 1; a positioning seat 3 18 and a push plate 3 20 are arranged between the lifting seat 3 and the outer tube of the lifting cylinder 2; a positioning seat 4 22 and a push plate 4 24 are arranged between the lifting seat 4 and the outer tube of the lifting cylinder 3; a push plate 5 27 is arranged between the lifting seat 5 and the outer tube of the lifting cylinder 4, the bottom of the lifting seat 5 is connected with the push plate 4, and the lifting cylinder 5 is arranged at the upper end of the push plate 5.

[0023] Furthermore, positioning pins 29 are provided on the push plate 1 12 , the push plate 2 16 , the push plate 3 20 , the push plate 4 24 , and the push plate 5 27 .

[0024] Furthermore, the positioning pins 29 of the push plate 1 12, the push plate 2 16, the push plate 3 20, the push plate 4 24 and the push plate 5 27 are respectively connected to the columns and the outer tubes of the lifting cylinder 1, the lifting cylinder 2, the lifting cylinder 3 and the lifting cylinder 4.

[0027] Furthermore, the measuring instrument base 3 is installed on the upper end of the lifting cylinder 5.

[0028] When the utility model is used, the installation of the lifting mechanism on the robot is first completed through the action of the base, and then the measuring instrument is installed on the measuring instrument base. When the height of the measuring instrument needs to be adjusted, when it rises at high speed, the threaded shaft is driven to rotate through the action of the motor, the synchronous belt, and the synchronous wheel, and the threaded shaft drives the lifting seat 1 to rotate. At the same time, the push plate 1 and the lifting seat 1 push the upper end part to move upward. When the lifting seat 1 moves to the top of the threaded shaft, it stops rotating, and the lifting cylinder 1 is relatively fixed with the threaded shaft; when the threaded shaft continues to rotate, the inner cylinder of the lifting cylinder 1 keeps rotating synchronously, which also drives the lifting seat 2 to move upward (at this time, the lifting seat 2 The distance between the first seat and the lifting seat gradually increases. ), when the lifting seat 2 rises to the top, the inner cylinder of the lifting cylinder 2 forms an integral relationship with the inner cylinder of the lifting cylinder 1 and the threaded shaft. Under the continuous operation of the threaded shaft, the inner cylinder of the lifting cylinder 2 drives the lifting seat 3 to rotate. After the lifting seat 3 rotates to the top, the inner cylinder of the lifting cylinder 3 drives the lifting seat 4 to rotate. After the lifting seat 4 rotates to the top, the inner cylinder of the lifting cylinder 4 drives the lifting seat 5 to rotate. The lifting cylinder 5 is pushed up by the action of the lifting seat 5, thereby realizing the adjustment of the height of the measuring instrument; in the actual process, the lifting height can be accurately controlled by controlling the number of motor turns.

[0029] When it is necessary to reduce the high speed, the steps to be implemented are that the lifting cylinder one, the lifting cylinder two, the lifting cylinder three, the lifting cylinder four and the lifting cylinder five are moved downward in sequence.

[0030] The lifting cylinder 5 of the utility model realizes up and down movement, and the lifting cylinders 1, 2, 3 and 4 realize rotational movement or up and down movement.

[0031] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
