[0027] A first mounting plate 50 is disposed above the machine platform 10 and is perpendicular thereto. A straight through slot 51 is formed on the first mounting plate 50 and is perpendicular to the machine platform 10.

[0028] The top mechanism 20 includes a first top seat 22, a second top seat 23 and a bidirectional driving assembly 20. The bidirectional driving assembly 20 is arranged on the machine 10 corresponding to the front side of the first mounting plate 50.

The second mounting plate 32 is connected to the driving portion of the first lifting drive assembly 31 and extends through the linear through slot 51 to above the first top seat 22 and the second top seat 23. The apron assembly 34 is arranged on one side of the second mounting plate 32. The rotation drive assembly 33 is arranged on the other side of the second mounting plate 32 and is transmission-connected to the apron assembly 34.

[0030] The detection mechanism 40 includes two lateral drive components 41, two second lifting drive components 42 and two detection components 43. The two lateral drive components 41 are arranged on the front side of the first mounting plate 50 on both sides of the linear through groove 51, the two second lifting drive components 42 are respectively installed on the driving parts of the two lateral drive components 41, and the two detection components 43 are respectively installed on the driving parts of the two lifting drive components.

[0031] Preferably, the bidirectional drive assembly 20 of the present application is a bidirectional screw module.

The first top seat 22 and the second top seat 23 in the present application are respectively connected to the two threaded structures in opposite directions, so that movement towards or away from each other can be achieved. In specific implementation, if there are other types of bidirectional drive structures that can also meet the use requirements of the present application, personnel in this technical field can also make adaptive choices.

[0032] It is also preferred that the first lifting drive assembly 31, the two second lifting drive assemblies 42 and the two lateral drive assemblies 41 of the present application are all servo screw modules.
