Description

Technical Field

[0001] This utility model relates to the field of lead screw module technology, and in particular to an ultra-long lead screw module with a support device. Background Technology

[0002] In the field of industrial automation, ultra-long lead screw modules are widely used in various equipment requiring precise linear motion, such as CNC machine tools, automated production lines, and robots. Traditional ultra-long lead screw modules mainly achieve linear motion through the cooperation of the lead screw and nut, attempting to meet the basic requirements of equipment for precise movement of components and provide necessary motion control support for various industrial production processes.

[0003] Traditional ultra-long lead screw modules are prone to bending and deformation during long-distance movement due to the length of the lead screw. This causes the moving sleeve to wobble during movement, affecting motion accuracy. Furthermore, this wobble becomes more pronounced when the moving sleeve bears a heavy load, potentially causing the equipment mounted on it to malfunction. This is because traditional designs do not adequately consider the deformation of ultra-long lead screws under long-distance and heavy-load conditions and lack effective support structures to stabilize the movement of the moving sleeve. During equipment operation, the moving sleeve is subjected to impacts and vibrations from various factors such as motor drive and external vibrations. Traditional modules often lack reasonable buffering and shock absorption devices, and these impacts and vibrations are transmitted to the moving sleeve and the equipment mounted on it. Over time, this accumulation can damage equipment components, affecting the equipment's lifespan and working accuracy.

[0004] Therefore, those skilled in the art have provided an ultra-long lead screw module with a support device to solve the problems mentioned in the background art. Utility Model Content

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] Example 1:

[0026] Please refer to Figure 1-5An ultra-long lead screw module with a support device includes a base 1. Support plates 2 are fixedly connected to both sides of the top of the base 1. A lead screw body 3 is movably connected to the opposite side of the support plates 2 via bearings. A motor 4 is fixedly connected to one side of the support plates 2. The output end of the motor 4 is fixedly connected to one end of the lead screw body 3. A movable sleeve 5 is threadedly connected to the surface of the lead screw body 3. A movable support mechanism 6 is provided between the base 1 and the movable sleeve 5. The movable support mechanism 6 includes a connecting plate 61, which is fixed to the surface of the movable sleeve 5. A fixed frame 62 is fixedly connected to the bottom of the connecting plate 61. A movable plate 63 is provided in the inner cavity of the fixed frame 62. A spring 64 is fixedly connected to the top of the movable plate 63. The top of the spring 64 is fixedly connected to the top of the inner cavity of the fixed frame 62. A vertical rod 65 is fixedly connected to the bottom of the movable plate 63. A fixed frame 66 is fixedly connected to the bottom of the vertical rod 65. A roller 67 is rotatably connected to the inner wall of the fixed frame 66. Movable grooves 68 that move with the rollers 67 are fixedly connected to both sides of the base 1.

[0027] In this embodiment, the design of the movable support mechanism 6 effectively solves the problem of poor movement stability of traditional ultra-long lead screw modules. The cooperation of spring 64 and roller 67 provides buffering and stable support for the movable sleeve 5, ensuring that the movable sleeve 5 moves smoothly on the ultra-long lead screw, improving motion accuracy, meeting the usage requirements under long distance and heavy load conditions, and the overall design improves the performance and reliability of the lead screw module.

[0028] Example 2:

[0029] Reference Figure 1-5 The movable sleeve 5 has evenly distributed guide support rods 7 running through its surface. The guide support rods 7 are slidably connected to the movable sleeve 5. The two ends of the guide support rods 7 are fixedly connected to two support plates 2 respectively. A support plate is fixedly connected to the top of the movable sleeve 5. A fixing plate is fixedly connected to the top of the support plate. The fixing plate has symmetrically distributed fixing holes on its top. A threaded hole 8 for use with the lead screw body 3 is opened on one side of the movable sleeve 5. Sliding through holes 9 for use with the guide support rods 7 are opened at the four corners of one side of the movable sleeve 5. Mounting plates are fixedly connected to both sides of the base 1. Mounting plates have symmetrically distributed mounting holes on their tops. Mounting positioning grooves are opened on both sides of the top of the base 1. An evenly distributed anti-slip pad is fixedly connected to the bottom of the base 1. The anti-slip pad has anti-slip texture on its bottom. A first permanent magnet plate 10 is fixedly connected to the bottom of the movable sleeve 5. A second permanent magnet plate 11 is fixedly connected to the top of the base 1. The magnetic poles of the first permanent magnet plate 10 and the second permanent magnet plate 11 are the same on opposite sides.

[0030] In this embodiment: the guide support rod 7 provides precise guidance for the movement of the movable sleeve 5, further enhancing the stability of the movable sleeve 5's movement, preventing it from deviating during movement, ensuring the straightness of the screw module's movement, and improving the accuracy of equipment operation. The design of the support plate, fixing plate, and fixing holes facilitates the installation of other equipment or components on the movable sleeve 5, expanding the application range of the screw module and enabling it to better cooperate with other devices to meet the needs of different industrial production scenarios. The threaded hole 8 cooperates with the screw body 3 to realize the movement of the movable sleeve 5, and the sliding through hole 9 cooperates with the guide support rod 7. This design clarifies the connection method between the movable sleeve 5, the screw body 3, and the guide support rod 7, ensuring the coordinated work between the components, making the structure of the screw module more reasonable and stable. The mounting plate, mounting plate, and fixing hole are all included. The mounting holes and positioning slots facilitate the installation and precise positioning of the base 1, reducing adjustment time during installation, improving installation efficiency, and ensuring that the lead screw module can be accurately installed on other equipment or workbenches, guaranteeing the overall performance of the equipment. The anti-slip pads and anti-slip textures increase the friction between the base 1 and the placement surface, preventing the base 1 from shifting due to vibration or external forces during operation, improving the stability of the lead screw module during operation, and ensuring the safety of equipment operation. The repulsive force generated by the first permanent magnet plate 10 and the second permanent magnet plate 11 provides additional support for the moving sleeve 5, further reducing the burden on the roller 67 and spring 64, improving the smoothness of the moving sleeve 5, especially when bearing a large weight, effectively reducing the wear of the lead screw and support components, and extending the service life of the lead screw module.

[0031] The implementation principle of this utility model is as follows: In use, the support plates 2 on both sides of the top of the base 1 are connected to the lead screw body 3 through bearings. The motor 4 fixed on one side of the support plate 2 drives the lead screw body 3 to rotate. The movable sleeve 5 on the surface of the lead screw body 3 moves along the lead screw direction when the lead screw body 3 rotates through threaded engagement. The connecting plate 61 fixed on the surface of the movable sleeve 5 is connected to the bottom of the fixed frame 62. The movable plate 63 inside the fixed frame 62 is connected to the top of the inner cavity of the fixed frame 62 through the top spring 64, and can move up and down within the fixed frame 62. The vertical rod 65 at the bottom of the movable plate 63 is connected to the fixed frame 66. The roller 67 rotatably connected inside the fixed frame 66 engages with the movable grooves 68 on both sides of the base 1. When the movable sleeve 5 moves along the lead screw, the roller 67 moves in the movable groove 68. The inner rolling spring 64 can buffer the vibration and impact of the moving sleeve 5 according to the actual situation, providing stable moving support for the moving sleeve 5 and ensuring the stability of the moving sleeve 5 when moving on the ultra-long lead screw. It is especially suitable for long-distance movement. The guide support rod 7 penetrating the surface of the moving sleeve 5 is fixed to the support plate 2 at both ends, providing guidance for the movement of the moving sleeve 5 and ensuring that it moves in a straight line along the direction of the lead screw, thus enhancing the stability of movement. The first permanent magnet plate 10 at the bottom of the moving sleeve 5 and the second permanent magnet plate 11 at the top of the base 1 generate a repulsive force because their magnetic poles are the same on opposite sides, providing additional upward support for the moving sleeve 5, further reducing the burden on the roller 67 and spring 64, and improving the smoothness of the movement of the moving sleeve 5, especially when bearing a large weight.

[0032] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
