Description

Technical Field

[0001] This utility model relates to the field of hollow rotating platform technology, and in particular to a hollow rotating platform that facilitates the replacement of the turntable. Background Technology

[0002] The hollow rotary platform is a mechanical device that integrates precision transmission and convenient maintenance design. Its core feature is that the center of the worktable has a through hollow hole and the center of the turntable has a reserved through hole, allowing cables, air pipes, drive shafts, optical lenses or workpieces to pass through. This completely avoids the problems of pipe entanglement and pulling during rotation. The hollow structure reduces the extra space for pipe avoidance, making the overall layout of the equipment more compact, especially suitable for miniaturized and integrated equipment.

[0003] The core advantage of traditional installation methods is the rigid locking of mechanical connections. The evenly distributed bolts in the circumference can form a closed-loop force structure. Combined with the circumferential limiting of the positioning pins, the turntable and the platform body form a rigid whole. The preload of the bolts can ensure that the turntable has no risk of loosening or displacement under high-speed rotation, heavy-load start-stop or external impact scenarios. It is far superior to the elastic connection of some quick-change structures and has outstanding impact resistance.

[0004] However, traditional hollow rotary platforms mostly use bolt-fastened connections. When replacing them, it is necessary to disassemble the circumferentially distributed fixing bolts one by one. Some models also require the removal of auxiliary structures such as protective covers and pipeline supports. The process is cumbersome and has a low fault tolerance. In industrial production lines, turntables are often accompanied by oil and dust, and bolts are prone to corrosion or jamming, further increasing the difficulty of disassembly. In some cases, external force may be required to knock them, which may damage the turntable or the platform itself. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a hollow rotating platform that facilitates turntable replacement, aiming to improve the problem of turntables being difficult to disassemble and install.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A hollow rotary platform for easy turntable replacement includes a drive assembly, a transmission assembly mounted on the top of the drive assembly, a mounting plate inside the transmission assembly, a disc mounted on the top of the mounting plate, a T-shaped limiting block fixedly connected to the bottom of the disc, a slide rod slidably connected inside the mounting plate, a spring mounted on the outer wall of the slide rod, a ball head fixedly connected to one end of the slide rod, and a positioning assembly inside the T-shaped limiting block.

[0008] The above technical solution involves a drive assembly including a motor and a precision gearbox, providing high-precision rotational power; a transmission assembly including a precision crossed roller bearing, ensuring high rigidity and rotational accuracy; and a mounting plate placed inside the transmission assembly, with the T-shaped limit block fixed at the bottom of the disc engaging with the mounting plate for quick installation.

[0009] Preferably, the positioning component includes a positioning hole, which is formed inside the T-shaped limiting block. The top of the mounting plate is provided with an I-shaped groove, and the inside of the mounting plate is provided with a sliding groove. One end of the I-shaped groove is provided with a limiting groove.

[0010] Preferably, the slide rod is slidably connected inside the T-shaped limiting block, and the ball head is mounted on one end of the spring.

[0011] Preferably, the sliding groove communicates with the I-beam groove, and the limiting groove communicates with the top of the I-beam groove.

[0012] Preferably, the T-shaped limiting block is slidably connected inside the I-shaped groove, and the T-shaped limiting block is slidably connected inside the limiting groove.

[0013] Preferably, the slide rod is slidably connected inside the slide groove, the slide rod is slidably connected inside the I-shaped groove, and the slide rod is slidably connected inside the positioning hole.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, pulling the ball head causes the slide rod to slide, and the positioning hole at the bottom of the T-shaped limit block is aligned with the slide groove opened inside the mounting plate. Then, the ball head is released to allow the slide rod to slide into the positioning hole to achieve installation.

[0016] 2. In this utility model, a spring is used to prevent the sliding rod from loosening. It is only necessary to align the rotating disc. The installation efficiency is improved by the cooperation between the I-shaped groove and the limiting groove at the top of the mounting plate. The quick positioning is achieved by the cooperation between the sliding rod and the positioning hole. Attached Figure Description

[0025] A hollow rotary platform for easy turntable replacement includes a drive assembly 1, a transmission assembly 2 mounted on the top of the drive assembly 1, a mounting plate 3 inside the transmission assembly 2, a disc 4 mounted on the top of the mounting plate 3, a T-shaped limiting block 5 fixedly connected to the bottom of the disc 4, a slide rod 6 slidably connected inside the mounting plate 3, a spring 7 mounted on the outer wall of the slide rod 6, a ball head 8 fixedly connected to one end of the slide rod 6, and a positioning assembly inside the T-shaped limiting block 5.

[0026] Specifically, the T-shaped limiting block 5 fixed at the bottom of the disc 4 is aligned with the limiting groove 12 opened at the top of the mounting plate 3, so that the T-shaped limiting block 5 can slide into the I-shaped groove 10. Then, the disc 4 is rotated so that the T-shaped limiting block 5 slides to the other end of the I-shaped groove 10. At this time, the ball head 8 is pulled to drive the slide rod 6 to slide. The positioning hole 9 opened at the bottom of the T-shaped limiting block 5 is aligned with the slide groove 11 opened inside the mounting plate 3. Then, the ball head 8 is released so that the slide rod 6 slides into the positioning hole 9 to complete the installation.

[0027] Reference Figure 3 The positioning component includes a positioning hole 9, which is opened inside the T-shaped limiting block 5. The top of the mounting plate 3 is provided with an I-shaped groove 10, and the inside of the mounting plate 3 is provided with a sliding groove 11. One end of the I-shaped groove 10 is provided with a limiting groove 12.

[0028] Specifically, the installation efficiency is improved by the cooperation between the I-shaped groove 10 and the limiting groove 12 at the top of the mounting plate 3, and the quick positioning is achieved by the cooperation between the sliding rod 6 and the positioning hole 9.

[0029] Reference Figure 2 The slide rod 6 is slidably connected inside the T-shaped limit block 5, and the ball head 8 is installed at one end of the spring 7.

[0030] Specifically, the spring 7 prevents the slide rod 6 from loosening. Simply align the rotating disc 4 and pull the ball head 8 to achieve quick installation. To disassemble, simply pull the ball head 8 again to disengage the slide rod 6 from the positioning hole 9, and then reverse the disc 4 to disengage it from the I-groove 10 to achieve quick disassembly.

[0031] Reference Figure 2 The sliding groove 11 is connected to the I-shaped groove 10, and the limiting groove 12 is connected to the top of the I-shaped groove 10.

[0032] Specifically, the installation efficiency is improved by the cooperation of the I-shaped groove 10 and the limiting groove 12 opened at the top of the mounting plate 3. The combination of the I-shaped groove 10 and the limiting groove 12 ensures the precise alignment between the components and avoids installation failure due to human error.

[0033] Reference Figure 2 The T-shaped limiting block 5 is slidably connected inside the I-shaped groove 10, and the T-shaped limiting block 5 is slidably connected inside the limiting groove 12.

[0034] Reference Figure 3 The slide rod 6 is slidably connected inside the slide groove 11, the slide rod 6 is slidably connected inside the I-shaped groove 10, and the slide rod 6 is slidably connected inside the positioning hole 9.

[0035] Specifically, rapid positioning is achieved through the cooperation of slide rod 6 and positioning hole 9. The tight cooperation between slide rod 6 and positioning hole 9 further enhances the integrity of the structure and effectively prevents loosening or displacement that may occur during use.

[0036] Working principle: The drive assembly 1 consists of a motor and a precision gearbox, providing high-precision rotational power. The transmission assembly 2 includes precision crossed roller bearings to ensure high rigidity and rotational accuracy. Installation is achieved by placing the mounting plate 3 inside the transmission assembly 2 and utilizing the T-shaped limiting block 5 fixed at the bottom of the disc 4 in conjunction with the mounting plate 3. Specifically, the T-shaped limiting block 5 at the bottom of the disc 4 is aligned with the limiting groove 12 at the top of the mounting plate 3, allowing the T-shaped limiting block 5 to slide into the I-beam groove 10. Then, the disc 4 is rotated, causing the T-shaped limiting block 5 to slide to the other end of the I-beam groove 10. At this point, the ball head 8 is pulled, causing the sliding rod 6 to slide. Through the sliding groove 11 inside the mounting plate 3, the bottom of the T-shaped limiting block 5... Align the positioning hole 9 with the slide groove 11, loosen the ball head 8, and slide the slide rod 6 into the positioning hole 9 to complete the installation. The function of the spring 7 is to prevent the slide rod 6 from loosening. Simply align the rotating disc 4 and pull the ball head 8 to achieve quick installation. When disassembling, pull the ball head 8 again to disengage the slide rod 6 from the positioning hole 9, and reverse the disc 4 to disengage it from the I-beam groove 10 for quick disassembly. The cooperation between the I-beam groove 10 and the limiting groove 12 at the top of the mounting plate 3, as well as the cooperation between the slide rod 6 and the positioning hole 9, together improve the installation efficiency. This design not only simplifies the operation steps but also significantly improves the stability and reliability of the equipment. This efficient installation method is particularly suitable for work scenarios that require frequent changes of the turntable, greatly reducing maintenance time and labor costs.
