Description

Technical Field

[0001] The utility model relates to the field of linear modules, in particular to a linear module with a limiting structure. Background Art

[0002] Ball screws are ideal products for converting rotary motion into linear motion, or vice versa. Ball screws are the most commonly used transmission components in tool machinery and precision machinery. Their main function is to convert rotary motion into linear motion, or torque into axial repetitive force, while also featuring high precision, reversibility, and high efficiency.

[0003] When installing the existing ball screw, it is extremely inconvenient to position the bearing seat for installing the screw, and the positioning cannot be adjusted quickly. The adjustment flexibility is poor. In the process of adjustment, due to the limitation of the size of the mounting plate at the lower end of the bearing seat, the adjustment range is small and the adjustment effect is average. In the positioning devices of some ball screws, slide rails are used for adjustment and positioning. Although the adjustment can be performed quickly, a single screw is used to fix it after adjustment, and the fixing effect is poor. In order to ensure that the corresponding structure does not fall off the slide rail, a limit block is set at the end of the slide rail, but the position of the limit block cannot be adjusted, and the use effect is average.

Through the provided guide rail 2, slider 6, adjustment plate 7 and fastening assembly 8, the position of the bearing seat 3 can be effectively adjusted and positioned to ensure the use accuracy of the ball screw. The fastening assembly 8 is symmetrically provided on the adjustment plate 7 to improve the stability of the adjustment plate 7 when in use. The lower end of the tightening screw 802 is connected to the tightening block 804 through the tightening head 803, which expands the contact area with the guide rail 2. While ensuring fastening, it will not cause damage to the guide rail 2.

[0018] When installing and positioning the ball screw, a nut seat 5 is set on the screw rod 4, and the shaft at the end of the screw rod 4 is connected to the bearing seat 3, and the bearing seat 3 is installed on the guide rail 2 through the adjusting plate 7 and the slider 6. When the position of the screw rod 4 is adjusted, the adjusting plate 7 moves along the guide rail 2 through the slider 6, thereby moving the screw rod 4 and the nut seat 5 through the bearing seat 3.
