Description

Technical Field

[0001] This utility model belongs to the field of ball screw technology, specifically relating to a ball screw drive platform. Background Technology

[0002] Ball screws are ideal products for converting rotary motion into linear motion, or vice versa. A ball screw consists of a screw, a screw nut, and balls. Its function is to convert rotary motion into linear motion. This is a further extension and development of ball screws. The important significance of this development is that it changes the bearing from rolling motion to sliding motion. Due to its very low frictional resistance, ball screws are widely used in various industrial equipment and precision instruments.

[0003] Currently, existing ball screw driven platforms still have some shortcomings. They often require manual adjustment during operation, which is time-consuming and labor-intensive. Moreover, the accuracy of manual adjustment is not high, which reduces their effectiveness. Therefore, we propose a ball screw driven platform. Utility Model Content

[0004] The purpose of this utility model is to provide a ball screw driven platform to solve the problems mentioned in the background art, which require manual adjustment during driving, which is time-consuming and laborious, and the manual adjustment is not accurate, thus reducing its effectiveness.

[0006] Preferably, the slide groove is provided with a threaded rod, the threaded rod is rotatably connected to the slide groove, the slider is rotatably connected to the slide groove, and a motor is provided at one end of the threaded rod.

[0007] Preferably, a limiting block is fixedly connected to the bottom of the lead screw nut, a limiting rod is provided inside the lower part of the fixing frame, the limiting rod is rotatably connected inside the fixing frame, and the limiting block is slidably connected to the outside of the limiting rod.

[0008] Preferably, the bottom of the device platform is provided with a slot, and a block is fixedly connected to the top of the slider. The block is adapted to the slot and is engaged inside the slot.

[0010] Preferably, the bottom of the fixing frame is fixedly connected with anti-slip protrusions, and the number of anti-slip protrusions is several.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By allowing the slider to move automatically inside the groove, the lead screw nut moves outside the lead screw body, allowing the equipment platform to follow the lead screw nut. This eliminates the need for manual adjustment, saving time and effort, improving adjustment accuracy, and enhancing the overall performance.

[0013] 2. By starting the motor, the threaded rod rotates, driving the slider to move inside the slide groove, which brings convenience to the automated operation. The limit blocks and limit rods improve the stability when the screw nut moves outside the screw body. The locking blocks and locking slots facilitate the installation and replacement of the equipment platform. Attached Figure Description
