Description

Technical Field

[0001] The utility model relates to the field of ball screws, and specifically relates to a supporting device for a ball screw. Background Art

[0002] A ball screw is a transmission device that converts rotational motion into linear motion, mainly composed of components such as a screw rod, a nut, and steel balls. When the screw rod rotates, the pressure applied by a preloading piece causes the steel balls to roll between the spiral grooves of the screw rod and the nut. Since the rolling friction coefficient of the steel balls is much smaller than the sliding friction coefficient, the ball screw can achieve high-efficiency and high-precision linear motion and is widely used in various precision machinery and industrial equipment. The supporting mechanism of the ball screw is an important mechanism for installing and supporting the ball screw. However, in the traditional supporting mechanism, since the two side support plates are fixed and the distance between the two side support plates cannot be adjusted, this results in that the supporting mechanism can only install ball screws of a certain length and cannot install ball screws of different lengths. In addition, the traditional supporting mechanism is rather troublesome when installing and disassembling the ball screw, wasting time. Therefore, a supporting device for a ball screw is proposed.

By setting the drive motor 4, the threaded rod 5, and the support plates 8, starting the drive motor 4 drives the threaded rod 5 to rotate, causing the right support plate 8 to move, changing the distance between the two support plates 8, and realizing the installation of ball screw mechanisms 201 of different lengths, which is practical.

[0024] Inside the support plate 8, a second bearing 9 is fixedly connected. The inner ring of the second bearing 9 is fixedly connected with a connecting rod 10. The other end of the connecting rod 10 is fixedly connected with an installation housing 11. The installation housing 11 includes a housing base 111 and a semi-circular housing 112.

The rotating device 12 includes a fixed block 121, a first fixing plate 122, a stator 123, a rotor 124, and a second fixing plate 125. By setting the stator 123 and the rotor 124, the semi-circular housing 112 rotates around the stator 123 as the rotor 124 rotates around the stator 123, realizing the opening and closing of the installation housing 11. The card slots 1111 inside the installation housing 11 clamp the clamping blocks 202, enabling the ball screw mechanism 201 to be installed between the two support plates 8. This mechanism is more convenient for installation and disassembly compared to traditional installation methods, saving a large amount of time and improving the installation and disassembly efficiency.

Then open the installation housing 11, place the clamping blocks 202 into the card slots 1111 provided inside the housing base 111. Then the rotor 124 rotates around the stator 123, causing the semi-circular housing 112 to close with the housing base 111, closing the installation housing 11, and realizing the installation of ball screws of different lengths.
