A beam of a gantry-type stage structure includes an accommodating space defined by a lower plate, an upper plate, a front plate, a rear plate and two lateral plates. A truss unit is disposed in the accommodating space, and includes lower and upper joint members which are respectively disposed on the lower and upper plates, first and second vertical members which extend uprightly from the lower and upper joint members, respectively, and diagonal members each of which extends to interconnect one lower joint member and an adjacent upper joint member to provide the beam with a great structural strength and a lightweight structure.

A lifting mechanism with self-locking function, including an ascending/descending seat, a rocking member pivotally connected with the ascending/descending seat, a guide section and a prestressing section. The rocking member serves to convert a horizontal force provided by a power source into a vertical force to up and down reciprocally move the ascending/descending seat in the direction of Z-axis. The guide section includes guide members, which can be cross roller ways for guiding the ascending/descending seat to ascend/descend. The prestressing section can be adjusted to change the gaps between fixed guide rails and movable guide rails of the cross roller ways. Accordingly, the sliding friction between the fixed guide rails and the movable guide rails can be adjusted to provide auxiliary locking force for locating the ascending/descending seat.

A two-dimension linear platform comprises a first displacement module and a second displacement module. The first displacement module includes a carrying member, at least one active linear module and at least one passive linear module. The active linear module and the passive linear module of the first displacement are parallel and opposite each other and are both disposed on the carrying member of the first displacement module. The second displacement module includes a carrying member, at least one active linear module and at least one passive linear module. The carrying member of the second displacement module is disposed on the active linear module and the passive linear module of the first displacement module. The active linear module and the passive linear module of the second displacement module are parallel and opposite each other and are disposed on the carrying member of the second displacement module.

A preloading and flex resistant support board for a mechanical machine comprises a support board body and at least one preloading bar. The support board body is formed with at one preloading groove in the side subjected to the compressive stress. The preloading groove is provided with two resisting surfaces. The preloading bar is also provided with two resisting surfaces. The preloading bar is assembled in the preloading groove of the support board body by screw, so as to provide a balance between the preloading capacity produced by preloading bar to the support board body and the flexing stress produced by the support board body.

A positive load alignment mechanism comprises a platform device in which are disposed a plurality of driving devices, movable devices and movable bearing platforms. The driving device is connected to the movable device, and the movable bearing platform firmly supports a movable platform of the platform device. The driving devices are used to drive the movable devices to perform the back-and forth or left-and-right or rotating movement, and the movable bearing platforms firmly support the movable platform. By such arrangements, it can achieve the objectives of high pressure resistance, simplified structure, high security, high accuracy and all-direction displacement.

An origin microadjustment mechanism for a linear motor is assembled on a stator of the linear motor and comprises a load bearing member fixed to a sensing member and two positioning seats. The load bearing member is movably passed through the positioning seats, and the positioning seats are fixed to the stator, so as to adjust the position of the sensing member relative to the stator.
