Sealed linear module and manufacturing method thereof

Abstract

The invention discloses a high-precision transmission device and provides a sealed linear module. The sealed linear module comprises a module profile, and the section of the module profile is in a U shape. The module profile comprises a profile bottom plate and profile side walls on the two sides of the profile bottom plate. A sealing strip assembly for sealing is arranged on the profile side walls in a matched mode, end covers are arranged at the two ends of the profile side walls in a matched mode, and a sealed space where a module sliding component is mounted and moved is defined. The sealing strip assembly comprises a sealing strip made of a plastic material. The module sliding component comprises a sliding block assembly and a sliding block connection box. The sliding block connection box is provided with a strip penetrating structure allowing the sealing strip to penetrate through. The sealing strip is provided with a contraction section matched with the strip penetrating structure, so that when the sliding block connection box runs along with the sliding block assembly, the sealing strip and the profile side walls are kept in the sealed state. By means of the linear module, an operation device can be installed conveniently or modules can be spliced conveniently. The sealing strip is provided with the contraction section correspondingly, the sealed state of the module is not affected when the sliding block connection box moves, and it is ensured that the screw type linear module keeps running with high precision for a long time.

Description

technical field [0001] The invention relates to a high-precision transmission device, in particular to a closed linear module and a manufacturing method thereof. Background technique [0002] As a high-precision transmission device, the linear module has been widely used in measurement, laser welding, laser cutting, small CNC machine tools, testing machines and applicable education and other places. It ensures the operation accuracy of these precision instruments and contributes to technological progress and society development plays an important role. Among the currently widely used linear modules, the screw-type linear module has become the focus of research and development because it meets higher precision requirements and can guarantee the accuracy of instrument operation to a greater extent. [0003] All parts in the screw-type linear module are precisely matched, especially the matching accuracy between the screw and the slider assembly, the slider assembly and the li...

Problems solved by technology

[0006] The object of the present invention is to overcome the problem that the closed screw type linear module needs to be provided with a connecting module structure for connecting the operating device or the modules to assemble each other on the slider assembly, and the connecting module structure will move with the slider assembly. As a result, the linear module cannot be completely sealed, and the linear module cannot be guaranteed to maintain high-precision operation for a long time. A closed linear module and its manufacturing method are provided. The structure allows the connection end of the slider connection box to be set outside the sealing tape assembly, which is convenient for the installation of the operating device or the assembly between the modules; and the corresponding loosening section is set on the sealing tape, and the sealing tape is made of plastic material, so that the driving The movement of the slider connection box does not affect the closure of the module, ensuring long-term high-precision operation of the screw-type linear module
