Description

Technical Field

[0001] This utility model relates to the field of ball screws, specifically a ball screw that is easy to install. Background Technology

[0002] Ball screws, due to their high positioning accuracy, long lifespan, low pollution, and ability to perform high-speed forward and reverse transmission and changeover transmission, have gradually become important components in positioning and measurement systems in precision technology and the machinery industry. Ball screws achieve high-precision linear transmission primarily through the cyclic rolling of numerous steel balls between the screw and nut. As precision transmission elements, ball screws are widely used in CNC machine tools, industrial robots, precision positioning equipment, and other fields. They achieve high-precision displacement control by converting rotary motion into linear motion.

[0003] Existing ball screws suffer from the following drawbacks: Firstly, they typically employ simple threaded or flanged connections, lacking diverse connection structures. In complex automated equipment, ball screws need to connect to various types of components, such as drive motors, support structures, and actuators. Traditional connection methods struggle to meet these diverse needs, leading to cumbersome installation processes, requiring additional adapters or complex assembly procedures, making ball screws inconvenient for connecting to external equipment. Secondly, the end structures of existing ball screws often use standardized flanges or threaded interfaces, requiring specific connectors for connection to external equipment, making it difficult to adapt to diverse installation requirements. For example, when the spacing of the pre-drilled holes in the equipment does not match the flange bolt holes, additional adapters are needed, significantly increasing installation complexity. Furthermore, some ball screws are only fixed via end flanges, lacking axial auxiliary positioning structures, making them prone to slight displacement under vibration or load conditions, affecting transmission accuracy. Finally, during installation, the lack of effective fixing and support structures makes existing ball screws susceptible to loosening or positional misalignment. During equipment operation, especially under high-speed or heavy-load conditions, ball screws may experience slight displacement due to vibration or impact, leading to a decrease in transmission accuracy and affecting the stability and reliability of the equipment. Furthermore, traditional installation methods have high requirements for the installation environment and processes; improper installation may shorten the service life of the ball screw or even cause equipment failure, resulting in poor installation stability of the ball screw.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] The following is combined Figures 1-3 A detailed description of an easy-to-install ball screw according to this utility model is provided:

[0018] A ball screw that is easy to install includes a screw 1, an outer cylinder 13, and a fixed base 2. A fixing ring is fitted onto the surface of the screw 1, and the fixed base 2 is fitted onto the surface of the fixing ring. The fixed base 2 is rotatably connected to the screw 1 through the fixing ring. The surface of the fixed base 2 is provided with a plurality of through-holes 4 for long bolts, which are symmetrically arranged between adjacent bolt holes 4. A connecting sleeve 7 is provided at one end of the screw 1, and a fixing block 9 is provided at one end of the connecting sleeve 7. The surface of the fixing block 9 is provided with a plurality of slots 11. The connecting sleeve 7 extends outward from one end to form several connecting blocks 8, which are all equidistantly distributed along the circumference of the connecting sleeve 7. The surface of the fixing block 9 extends outward to form several fixing parts 12, which are all equidistantly distributed along the circumference of the fixing block 9. The surface of the fixing block 9 is provided with a fixing groove 10. One end of the screw 1 is provided with a flange 17, and the surface of the flange 17 is provided with several screw holes 18, which are symmetrically arranged between adjacent screw holes 18.

[0019] The surface of the fixed base 2 is provided with a plurality of fixing holes 3, which are symmetrically arranged between adjacent fixing holes 3. The depth of the fixing holes 3 is less than the height of the fixed base 2. The symmetrical arrangement of the fixing holes 3 on the surface of the fixed base 2 and the fact that the depth is less than the height of the fixed base 2 can prevent the bolts from being installed too deep and affecting the contact between the base and other mounting surfaces, ensuring the installation stability of the fixed base 2, while providing multiple installation options and improving installation flexibility.

[0020] A fixing plate 5 is provided on the side of the fixing base 2. Several short bolts 6 are provided on the surface of the fixing plate 5. The fixing plate 5 is threadedly connected to the fixing base 2 through the short bolts 6. The fixing plate 5 on the side of the fixing base 2 is threadedly connected to the fixing base 2 through the short bolts 6, which facilitates the installation and removal of the fixing plate 5.

[0021] A connecting plate 15 is provided on the side of the outer cylinder 13. The surface of the connecting plate 15 is provided with a plurality of through connecting holes 16. The through connecting holes 16 on the surface of the connecting plate 15 on the side of the outer cylinder 13 facilitate connection with other components, improve the integration and stability of the ball screw assembly, and make installation and disassembly more convenient.

[0022] The screw 1 is fitted with an inner cylinder 19. The surface of the inner cylinder 19 is provided with ball grooves 20, and several rolling balls 22 are disposed inside the ball grooves 20. The surface of the inner cylinder 19 is also provided with a return groove 21 that communicates with the ball grooves 20. The balls 22 circulate within the ball grooves 20 via the return groove 21. The surface of the outer cylinder 13 is provided with an oil injection hole 14. The inner cylinder 19 fitted with the screw 1 has ball grooves 20 and return grooves 21 on its surface. The ball 22 circulates within the ball groove 20, reducing friction between the inner cylinder 19 and the outer cylinder 13, improving transmission efficiency and accuracy, and extending the service life of the ball screw. When the ball screw rotates, the screw 1 drives the inner cylinder 19 to rotate together, and the ball 22 is transmitted between the ball groove 20 and the return groove 21. The oil injection hole 14 on the surface of the outer cylinder 13 facilitates the addition of lubricating oil, ensuring lubrication of the ball screw during operation, reducing wear, and improving the smoothness and reliability of operation.

[0023] This embodiment provides an easy-to-install ball screw. The long bolt holes 4 on the surface of the fixed base 2 facilitate bolt connection to external equipment. A slot 11 is provided on the surface of the fixing block 9 at one end of the connecting sleeve 7, allowing for engagement with other components and ensuring reliable connection. The fixing part 12 and fixing groove 10 on the surface of the fixing block 9 facilitate connection with other components, ensuring the stability of the ball screw connection. The bolt holes 18 on the surface of the flange 17 are symmetrically arranged, facilitating bolt connection with other components. This design makes it easy to connect both ends of the ball screw to external equipment, greatly improving installation stability.

[0024] When installing the ball screw, align the end with the connecting sleeve 7 with the external equipment to be installed. Push the fixing block 9 so that the fixing groove 10 on the fixing block 9 engages with the corresponding position on the external rotating equipment. This allows the fixing block 9 to slide into place, and the locking groove 11 on the fixing block 9 to also engage with the corresponding position on the external rotating equipment. The fixing part 12 positions the connecting sleeve 7, connecting the entire connecting sleeve 7 and the fixing block 9 to the external rotating equipment. After installing one end of the screw 1, insert a long bolt into the long bolt hole 4 on the fixing base 2 to stably connect one end of the ball screw to the external rotating equipment. The fixed base 2 is aligned with other components, and bolts are screwed into the fixing holes 3 on the fixed base 2 to achieve stable installation of the fixed base 2. At this time, bolts are screwed into the connecting holes 16 on the connecting plate 15 to achieve stable installation of the external linear component. Bolts are screwed into the screw holes 18 on the flange 17 to fix the other end of the ball screw. The output end of the external rotating device drives the connecting sleeve 7 to rotate, so that the connecting sleeve 7 and the screw 1 rotate together. The ball 22 circulates back and forth in the ball groove 20 and the return groove 21, so that the rotational motion of the screw 1 is converted into linear motion.
