[0002] With the rapid development of modern industrial technology, the demand for motion accuracy and stability of equipment has become increasingly stringent. As the core component to ensure the smooth movement of equipment, the performance of the slide rail is directly related to the overall operating efficiency and stability of the equipment. Although the traditional precision slide rail design has demonstrated reliability under high load and high speed conditions by means of screw transmission, this design has significant deficiencies in energy transmission.

[0003] Specifically, the traditional screw linear guide rail causes a large energy loss in the process of driving force transmission, which limits the improvement of transmission efficiency. In addition, due to the mechanical characteristics of the screw mechanism, the existing screw linear guide rail is often limited to reciprocating motion in a single position, and its motion mode and range are relatively fixed, which makes it difficult to meet the diversified and complex motion requirements in modern industry.

[0004] Therefore, it is very necessary to invent a precision slide rail device. Utility Model Content

[0020] As attached Figure 1 To Attachment Figure 3 As shown:

[0021] The utility model provides a precision slide rail device, comprising a guide rail seat 1, a driving slide seat mechanism 2, a base 3, a guide rail gear set 4 and a raised guide rail 5, wherein the guide rail seat 1 is fixedly mounted on the base 3, the guide rail gear set 4 and the raised guide rail 5 are arranged on the guide rail seat 1, and the driving slide seat mechanism 2 is installed on the guide rail gear set 4 and the raised guide rail 5.

[0022] The driving slide mechanism 2 includes a slide 21, a slide shaft 22, a roller 23, a worm 24, a driving component 25, a worm wheel 26 and a driving gear 27. The slide shaft 22 is rotatably mounted on the slide 21, the roller 23 is fixedly mounted on the slide shaft 22, and the roller 23 is rollingly mounted on the raised guide rail 5; the worm 24 is rotatably mounted in the slide 21, and either end of the worm 24 rotates through the slide 21 and is fixed to the output end of the driving component 25 fixedly mounted outside it; the worm 24 is meshed and connected with the worm wheel 26, and the worm wheel 26 and the driving gear 27 are rotatably mounted in the slide 21 through the core shaft, and the driving gear 27 is meshed with the guide rail gear set 4. The driving slide mechanism 2 adopts an innovative structural design, which is not only compact in structure but also highly efficient. Its core structure is carefully combined by precise gear racks and worm gear mechanisms.

[0023] Embodiment 1:

[0024] Specifically, the guide rail seat 1 is an annular structure, which not only enhances the stability of the overall structure, but also provides a basis for the realization of various motion trajectories. The guide rail gear set 4 is arranged on the outer surface of the guide rail seat 1. These gear teeth are precisely processed and arranged to ensure close meshing with the driving gear 27 in the driving slide mechanism 2, thereby achieving precise and stable transmission. The inner and outer surfaces of the guide rail seat 1 are mirror-imaged with the raised guide rails 5, which not only serve as the track for the rolling of the rollers, but also further enhance the motion stability and accuracy of the slide 21 on the guide rail seat 1 through its unique shape and layout. The raised guide rails 5 on both the inner and outer sides also ensure the smoothness and accuracy of the slide 21 in linear reciprocating motion and annular trajectory motion.

[0025] Specifically, there are two groups of sliding shafts 22, two in one group, and the two groups of sliding shafts 22 are respectively located on the inner side and the outer side of the guide rail seat 1. This layout ensures the stability of the slide 21 on the guide rail seat 1, and it can be evenly and stably supported both on the inner side and the outer side; two rollers 23 are fixedly mounted on each sliding shaft 22, so that the total number of rollers 23 reaches eight. These rollers 23 are evenly distributed between the slide 21 and the guide rail seat 1, which not only effectively reduces the friction resistance of the slide 21 during movement, but also improves the load-bearing capacity and stability of the slide 21. At the same time, the coordinated work of the eight rollers 23 further ensures the precise movement of the slide 21 on the guide rail seat 1, providing more stable and reliable movement support for the equipment.

[0026] Specifically, the slide 21 is an "L"-shaped structure, which not only provides sufficient installation space, but also makes the layout of the slide 21 on the guide rail seat 1 more reasonable. A mounting hole is provided on the upper surface of the slide 21. The mounting hole is convenient for the user to fix the slide 21 with other components of the equipment to ensure the stability and reliability of the slide 21. The worm 24 rotatably installed inside the slide 21 is located on one side of the driving gear 27, and the driving gear 27 is located on one side of the worm wheel 26.

[0027] Specifically, the driving gear 27 is located outside the guide rail seat 1, so that the slide 21 can achieve precise movement along the outside of the guide rail seat 1 through the close meshing of the driving gear 27 and the guide rail gear set 4. Driven by the driving component 25, the worm 24 rotates, driving the worm wheel 26 to rotate, and then driving the driving gear 27 to rotate. Due to the meshing of the driving gear 27 and the guide rail gear set 4, the slide 21 can perform linear reciprocating motion along the outside of the guide rail seat 1.

[0028] More importantly, due to the annular structure of the guide rail seat 1 and the raised guide rails 5 provided on both the inner and outer surfaces, the slide 21 can also realize annular track motion under the coordinated action of the driving gear 27 and the guide rail gear set 4. This motion mode not only increases the motion flexibility of the slide 21, but also broadens its application range in various industrial applications.

[0029] Embodiment 2:

[0030] First, driven by the driving component 25, the worm 24 rotates, and the driving gear 27 is driven to rotate through the worm wheel 26. The meshing of the driving gear 27 with the guide rail gear set 4 enables the slide 21 to perform precise linear reciprocating motion along the outer side of the guide rail seat 1. At the same time, with the help of the annular structure of the guide rail seat 1 and the raised guide rails 5 on the inner and outer sides, the slide 21 can also achieve circular trajectory motion. The entire workflow includes four stages: starting, linear reciprocating motion, circular trajectory motion, and stopping. By precisely controlling the rotation direction and speed of the worm 24, the slide 21 can achieve stable and efficient motion on various trajectories. It not only enhances the overall stability of the device, but also broadens its application scenarios, providing a high-performance motion control solution for modern industry.

[0031] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
