Positioning control structure of module working platform in precise positioning platform

The utility model discloses a positioning control structure of a module working platform in a precise positioning platform. The precise positioning platform comprises a base and the module working platform. A linear slide rail is arranged on the base, and the module working platform is arranged on the linear slide rail. The positioning control structure comprises a switch induction sheet and at least two limiting switches, wherein the limiting switches are arranged at intervals, and the switch induction sheet is fixed on the module working platform. The base comprises a side plate on one side of the base, a T-shaped sliding groove is formed in the side plate in the advancing direction of the module working platform, the limiting switches are connected with the sliding groove through a detachable connecting piece in a positioning mode, and the limiting switches can induct the switch induction sheet entering an induction area of the limiting switches and controls the closing and opening of a circuit of a drive motor. The positioning control structure is simple, the limiting switches can be fixed on the base very conveniently, the positioning control of the module working platform is achieved, the positions of the limiting switches can be flexibly moved, the dismounting process is very convenient, and the positioning control structure has the advantage of saving production cost.
