Description

Technical Field

[0002] As a high-precision transmission device, linear modules are currently widely used in measurement, laser welding, laser cutting, small CNC machine tools, testing machines, and education. They ensure the operating accuracy of these precision instruments and play an important role in scientific and technological progress and social development. Common screw-type linear modules include module profiles and pallets. The drive motor drives the pallet to move on the module profile through the screw nut mechanism. Since all components in the linear module are precisely matched, the straightness of the pallet movement needs to be tested after the linear module is assembled.

[0003] The utility model with publication number "CN213090704U" and name "A linear module support plate movement straightness detection device" discloses a detection device, which mainly uses the pointer deflection of the measuring meter to intuitively understand the movement of the linear module support plate, and the top plate and the movable plate remain parallel, which can ensure the verticality during the up and down movement.

[0004] In this device, the straightness of the linear template is mainly detected by a measuring table. The linear module is not fixed during the detection process. If the linear module shakes, the detection result is likely to be wrong, resulting in reduced inspection efficiency. Utility Model Content
