Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of linear motor modules, in particular to a linear motor module with a double support structure. BACKGROUND

[0002] The double support structure linear motor module is a device that uses two support points to fix and support the linear motor. This structure improves the stability and carrying capacity of the system by setting one support point at each end of the linear motor. Each support point is usually equipped with high-precision guide rails and bearings to ensure that the linear motor can maintain straight-line motion during operation, reducing friction and vibration. The double support structure also enhances the rigidity and anti-deformation ability of the motor, making it suitable for high-precision positioning and high-speed motion applications.

[0003] A linear motor module with a double support structure is disclosed in the utility model patent with publication number CN218648712U, which includes a protective box. The upper end of the protective box is provided with a transmission screw structure. The surface of the transmission screw structure is movably mounted with a bearing plate. The lower end of the protective box is arrayed with a storage plate. The lower end of the storage plate is arrayed with a damping assembly inside. The utility model cooperates the bearing plate, top plate, and damping assembly, and cooperates the rolling ball, guide rail, and bearing plate. When the bearing plate moves, it will press the corresponding top plate downward, causing the movable plate at the lower end to move along the inside of the storage plate, and then causing the damping assembly to be pressed downward, thereby facilitating the movement of the bearing plate. When vibration occurs, the damping assembly will alleviate the vibration generated during interaction, thereby increasing the stability of the bearing plate movement.

[0004] However, in actual use, it is found that the bearing plate of the device slides inside the protective box and is limited by the cooperation of the protrusion and the movable groove. At the same time, the damping assembly alleviates the vibration of the bearing plate during interaction.

[0005] However, since the bearing plate and the transmission screw structure are connected by threads, this connection limits the position of the bearing plate, making it difficult for the damping assembly inside the protective box to provide good cushioning and damping effect. In addition, the protective box of the device is an integrated structure, and is limited by the protrusion, making it difficult to conveniently disassemble the bearing plate from the inside of the protective box for maintenance or replacement. Therefore, a linear motor module with a double support structure is provided. Utility model content
