Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a keyway-guided linear adjustment support frame. Background Technology

[0002] A linear adjustment support frame is a mechanical device used to achieve precise linear position adjustment and provide stable support. Its core function is to allow the supported components (such as sensors, lenses, workpieces, etc.) to be adjusted in a controllable, repeatable, and high-precision manner along a specific linear direction (usually vertical or horizontal) while maintaining structural rigidity and stability.

[0003] Existing linear adjustment support frames mostly use ordinary guide rails or sliding bearings for guidance, which are prone to shaking, gaps and wear under lateral forces or off-center loads, resulting in insufficient structural rigidity and reduced repeatability. At the same time, they generally lack effective lubrication mechanisms, making it difficult to meet the requirements of stability, reliability and long-term adjustment performance in high-precision application scenarios.

[0004] To address the aforementioned issues, a keyway-guided linear adjustment support frame is required. Utility Model Content

[0005] To overcome the shortcomings of traditional guide rails or sliding bearings, which are prone to swaying, clearance, and wear under lateral forces or off-center loads, this utility model provides a linear adjustable support frame with keyway guidance.

[0006] The technical solution of this utility model is as follows: A linear adjustment support frame with keyway guidance includes a base, a guide rod, a first docking ring, a second docking ring, fixing bolts, sliding blocks, a top plate, a mounting frame, a lead screw, an oil pipe, and an electronic valve. The top of the base has symmetrically arranged first mounting holes on the left and right sides. A guide rod is fixedly connected to the center of the top surface of the base. Keyways are symmetrically arranged on the guide rod front and back. A first docking ring is located on the rear side of the guide rod, and a second docking ring is located on the front side of the guide rod. Multiple fixing bolts are threaded between the first and second docking rings. Sliding blocks are provided inside both the first and second docking rings, and the sliding blocks slide in cooperation with the keyways. A top plate is located on the top of the first docking ring. A mounting frame is located on the base. A lead screw is threaded inside the mounting frame, and the top of the lead screw rotates in cooperation with the top plate. Second mounting holes are symmetrically arranged on the left and right sides of the mounting frame. An oil pipe is embedded inside the guide rod, and an electronic valve is installed on the oil pipe.

[0007] In one embodiment, a mounting plate is also included, with a plurality of first mating holes symmetrically opened on the top plate in the front and back, and a second mating hole symmetrically opened on the top plate in the front and back.

[0008] In one embodiment, a limiting plate is also included, with the limiting plates symmetrically arranged on the left and right sides of the base.

[0009] In one embodiment, a rotating rod is also included, with the bottom end of the lead screw connected to the rotating rod.

[0010] In one embodiment, each first mounting hole overlaps with the position of the corresponding second mounting hole.

[0011] In one embodiment, the number of both the first mating hole and the second mating hole is no less than six.

[0012] Beneficial effects: By setting symmetrical keyways on the guide rod and using sliding blocks to achieve pure linear guidance, lateral offset, torsion, and sway are effectively suppressed, significantly improving structural rigidity and motion stability; the lead screw and top plate adopt a rotating fit, combined with threaded transmission, to accurately convert rotational motion into axial displacement, ensuring high repeatability positioning accuracy; the first and second circumferential coupling rings clamp the guide rod with fixing bolts, further enhancing overall rigidity and resistance to eccentric loads; the guide rod integrates oil pipes and electronic valves, which can automatically supply lubricating or damping oil as needed, reducing friction and wear, and extending service life, especially suitable for high-frequency adjustment or heavy-load conditions; the base and placement frame are quickly positioned by limiting plates, and convenient and stable overall installation is achieved by utilizing the overlapping first and second mounting holes.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0020] Example: A keyway-guided linear adjustment support frame, such as Figures 1-5 As shown, the device includes a base 1, a guide rod 3, a first docking ring 5, a second docking ring 6, a fixing bolt 7, a sliding block 8, a top plate 9, a mounting bracket 10, a lead screw 11, an oil pipe 13, an electronic valve 14, a mounting plate 16, a limiting plate 18, and a rotating rod 19. The base 1 has symmetrically arranged first mounting holes 2 on its top. A guide rod 3 is fixedly connected to the center of the top surface of the base 1, serving as the sliding guide body. It integrates an internal oil circuit and has a keyway 4 on its exterior to provide a high-rigidity linear motion track for the sliding block 8. The guide rod 3 also has symmetrically arranged keyways 4 on its front and back to limit... Except for the axial direction, all degrees of freedom ensure smooth, non-shaking, and non-deflecting motion, achieving precise linear guidance. A first docking ring 5 is located at the rear of the guide rod 3, and a second docking ring 6 is located at the front of the guide rod 3. Multiple fixing bolts 7 are threaded between the first docking ring 5 and the second docking ring 6. Sliding blocks 8 are provided inside both the first and second docking rings 5 ​​and 6, respectively. The sliding blocks 8 slide with the keyway 4 and slide along the guide rod 3 with the top plate 9, directly transmitting and adjusting displacement while ensuring motion accuracy. A top plate 9 is located on the top of the first docking ring 5, and a placement rack 10 is provided on the base 1. The placement frame 10 is internally threaded with a lead screw 11. The top end of the lead screw 11 is rotatably engaged with the top plate 9. Rotation converts angular displacement into axial linear displacement of the top plate 9, achieving precise adjustment. Symmetrical second mounting holes 12 are provided on the left and right sides of the placement frame 10. Each first mounting hole 2 overlaps with its corresponding second mounting hole 12 for secondary locking of the entire device, improving installation stability. An oil pipe 13 is embedded inside the guide rod 3, serving as a channel for delivering lubricating or damping oil, connecting the electronic valve 14 to the keyway mating area. An electric valve is installed on the oil pipe 13. The sub-valve 14 has multiple first docking holes 15 symmetrically opened on the top plate 9. The top plate 9 is provided with a mounting plate 16, which serves as the direct mounting carrier for the final load. Various equipment can be quickly fixed through the docking holes. The top plate 9 has second docking holes 17 symmetrically opened on the top plate 9. The number of first docking holes 15 and second docking holes 17 is not less than six. The base 1 is provided with symmetrical limit plates 18 on the left and right sides, which are used to achieve rapid lateral positioning when installing the placement frame 10, ensuring its center alignment and improving assembly efficiency and consistency. The bottom end of the lead screw 11 is connected to a rotating rod 19.

[0021] In use, first place the base 1 in a suitable installation position, and then place the placement frame 10 on the base 1, ensuring that its two sides are tightly against the symmetrically arranged limiting plates 18, thereby achieving rapid positioning of the placement frame 10. Next, place the first docking ring 5 on the rear side of the guide rod 3, and then place the second docking ring 6 on its front side, and secure them together with multiple fixing bolts 7 to form a stable ring structure that clamps the guide rod 3. Then, using the overlapping first mounting hole 2 (located in the base 1) and second mounting hole 12 (located in the placement frame 10), firmly install the entire device onto the external platform. During operation, rotate the rotating rod 19 at the bottom of the lead screw 11, causing the lead screw 11 to rotate within the placement frame 10. Since the lead screw 11 and the placement frame 10 are threadedly engaged, while its top end is rotated with the top plate 9 (allowing relative rotation but restricting axial disengagement), the rotational motion of the lead screw 11 is converted... To ensure precise linear displacement of the top plate 9 along the guide direction, the top plate 9 is connected to the sliding block 8 via the first mating ring 5. The sliding block 8 is embedded in the keyways 4 symmetrically opened at the front and rear of the guide rod 3 and slides with it, ensuring that the entire movement process is carried out only along a single axis, effectively suppressing deflection, lateral displacement and swaying, and ensuring high rigidity and high repeatability positioning accuracy. In addition, the guide rod 3 is embedded with an oil pipe 13, and the oil pipe 13 integrates an electronic valve 14, which can be opened and closed by an external control system to supply lubricating or damping oil to the mating surface of the keyway 4 and the sliding block 8 as needed, significantly reducing frictional resistance and improving the smoothness of movement, especially suitable for high-frequency adjustment or heavy-load conditions. The top plate 9 is provided with a mounting plate 16, and through no less than six first mating holes 15 and second mating holes 17, it realizes the rapid, reliable installation and precise positioning of loads (such as optical components, sensors, etc.), meeting the application requirements of modularity and high compatibility.
