Description

Technical Field

[0001] The present application relates to the technical field of linear guide rails, and in particular to a rotatable and adjustable linear guide rail. Background Art

[0002] A linear guide is a mechanical component used to achieve high-precision linear motion. It is mainly composed of two parts: a guide rail and a slider. The guide rail is a precision-machined linear track with high straightness and flatness, which can provide precise guidance for motion. The slider works closely with the guide rail, and its interior usually contains rolling elements such as balls or rollers. When working, the slider moves linearly along the guide rail, and the rolling elements roll between the two, making the slider's movement friction extremely low, and can achieve smooth and precise displacement. Linear guides are widely used in various precision equipment, such as machine tools, to ensure that the tool cuts accurately along a straight line during the processing process, greatly improving the processing accuracy; in automated equipment, such as robotic arms, linear guides can ensure that its end effector performs precise linear motion, effectively improving the equipment's work efficiency and product quality.

[0003] With the continuous development of industrial technology, the requirements for welding processing and cylindrical columnar product processing are becoming increasingly higher. In these processing processes, it is necessary to fully process the outer surface of the product at 360 degrees to ensure the quality and performance of the product. However, the existing linear guides have obvious defects and deficiencies in meeting this demand.

[0004] Existing linear guides are generally designed to achieve precise motion in a straight line, and their structure and function are mainly focused on providing guidance and support in a single direction. In welding processing and cylindrical product processing, existing linear guides cannot achieve 360-degree full-range motion around the product, which greatly limits the processing process. For example, in welding processing, existing linear guides can only move welding equipment in a straight line direction, and cannot perform continuous and comprehensive welding operations at different angles of the product. This not only reduces welding efficiency, but may also lead to unstable welding quality because the position of the product or the angle of the welding equipment needs to be frequently adjusted to complete comprehensive welding. For the processing of cylindrical products, such as surface grinding and polishing, existing linear guides are also unable to meet the requirements of 360-degree comprehensive processing. The processing equipment can only move within a limited straight line range and cannot evenly and consistently process the entire outer surface of the product. Uneven processing is prone to occur, affecting the appearance and performance of the product. In summary, existing linear guides have obvious defects in welding processing and cylindrical product processing, and cannot meet the requirements of 360-degree comprehensive processing of the outer surface of the product. A new guide system is urgently needed to solve this problem. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the technical solutions in this application, the following will provide a clear and complete description of the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0029] Example

[0030] refer to Figures 1 to 4 The present embodiment provides a rotatable and adjustable linear guide rail, comprising: a ring rail 100, wherein the ring rail 100 is interactively connected to a rotating mechanism 200, wherein the top of the rotating mechanism 200 is fixedly connected to an angle adjustment mechanism 300, and a linear guide rail mechanism 600 is movably mounted on the top of the angle adjustment mechanism 300;

[0031] The rotating mechanism 200 includes a slip ring 210 and a drive assembly 220. The slip ring 210 is slidably connected to the inside of the annular rail 100. A fixed block 230 is fixedly connected to the top side of the slip ring 210. The top of the fixed block 230 is connected to the bottom of the angle adjustment mechanism 300. The drive assembly 220 is installed on the inner side of the annular rail 100. The drive assembly 220 and the slip ring 210 are transmission-connected. The rotating mechanism 200 inside the annular rail 100 enables the entire device to rotate around the product. The slip ring 210 slides smoothly in the annular rail 100 and is connected to the angle adjustment mechanism 300 through the fixed block 230 at the top, providing stable support for the angle adjustment mechanism 300 and the linear guide mechanism 600. The drive assembly 220 is transmission-connected to the slip ring 210, which can accurately control the rotation of the slip ring 210, thereby assisting in driving the linear guide mechanism 600 to rotate around the product to be processed, greatly facilitating adaptation to various production and processing requirements and providing strong support for efficient production. At the same time, combined with the angle adjustment mechanism 300 and the linear guide rail mechanism 600 at the top, the linear displacement direction, position and angle of the guide rail body 630 can be flexibly adjusted, thereby improving the adaptability and meeting the diverse requirements of different processing scenarios.

[0032] The driving assembly 220 includes a base plate 221, a notch 222 and an annular groove 223. The base plate 221 is fixedly connected to one side of the bottom of the annular rail 100. The notch 222 is opened on one side of the annular rail 100 close to the base plate 221. The annular groove 223 is opened on the inner side of the slip ring 210. The bottom of the base plate 221 is fixedly connected to the first motor 224. The output end of the first motor 224 passes through the base plate 221 and is fixedly connected to a gear 225. The inner side of the annular groove 223 is fixedly connected to an inner gear ring 226. The inner gear ring 226 and the gear 225 are meshed and connected. The base plate 221 provides a stable installation position for the first motor 224 to ensure the stability of the motor during operation. The setting of the notch 222 enables the gear 225 to smoothly mesh with the inner gear ring 226 in the annular groove 223 inside the slip ring 210 for transmission. When the first motor 224 is running, the gear 225 at its output end can accurately drive the inner gear ring 226 to rotate. Since the inner gear ring 226 is fixed on the inner side of the annular groove 223 of the slip ring 210, the rotation of the inner gear ring 226 will drive the slip ring 210 to slide inside the annular rail 100. This transmission method is accurate and reliable, and can achieve precise control of the rotation of the slip ring 210, thereby assisting in driving the linear guide mechanism 600 to rotate around the product to be processed, meeting various production and processing needs, and providing strong technical support for efficient production.

[0033] The bottom of the ring rail 100 is fixedly connected to a fixing bracket 500 at equal intervals in a circular pattern. The bottom of the fixing bracket 500 is fixedly connected to a fixing plate 400. The cross-sectional shape of the slip ring 210 and the internal cross-section of the ring rail 100 are both convex. The top of the fixing plate 400 has a mounting hole 700, which is a countersunk hole. The overall combination of the fixing bracket 500 and the fixing plate 400 is arranged in an L-shape. The fixing bracket 500, which is fixedly connected to the bottom of the ring rail 100 at equal intervals in a circular pattern, provides stable support for the ring rail 100. The fixing plate 400 at the bottom of the fixing bracket 500 further enhances the stability of the entire device. The mounting hole 700 at the top of the fixing plate 400 is a countersunk hole design, making the installation more aesthetically pleasing and avoiding interference with other components. The cross-sectional shape of the slip ring 210 and the internal cross-sectional shape of the ring rail 100 are both convex, ensuring the stable sliding of the slip ring 210 within the ring rail 100 and preventing it from falling out. The overall combination of the fixing frame 500 and the fixing plate 400 is L-shaped. This design structure is reasonable, which not only ensures the strength of the support, but also saves space, providing convenience for the installation and use of the device.

[0034] The angle adjustment mechanism 300 includes a carrier plate 310, which is fixedly connected to the top of the fixed block 230. Both sides of the top of the carrier plate 310 are fixedly connected with hinges 320. The top of the carrier plate 310 is fixedly connected to a fixed column 330. The top of the fixed column 330 is hinged with a hinge seat 340. The top of the hinge seat 340 is fixedly connected to a top plate 350. The top of the top plate 350 is connected to the bottom of the linear guide mechanism 600. Both sides of the bottom of the top plate 350 and both sides of the top of the carrier plate 310 are also fixedly connected with hinges 320. An electric push rod 360 is hingedly installed between the top plate 350 and the inner side of the carrier plate 310 through the hinge 320. The guide rail mechanism 600 includes a guide rail base plate 620, which is bolted to the top of the top plate 350. The top of the guide rail base plate 620 is fixedly connected to the guide rail body 630. The outer surface of the guide rail body 630 is slidably connected to the slider 640. The inner side of the guide rail body 630 is rotatably connected to the screw rod 650. One side of the guide rail body 630 is fixedly connected to the second motor 610. The output end of the second motor 610 is fixedly connected to one end of the screw rod 650. The slider 640 is threadedly connected to the outer surface of the screw rod 650. In the angle adjustment mechanism 300, the support plate 310 is connected to the rotating mechanism 200 via the fixed block 230, providing stable support for the entire structure. The hinged seat 340 hinged to the top of the fixed column 330 and the top plate 350 connected thereto, in conjunction with the electric push rod 360, can achieve flexible angle adjustment. By extending and retracting the electric push rod 360, the left and right rotation angles of the top plate 350 can be easily adjusted, thereby adjusting the stroke angle of the linear guide mechanism 600, thereby improving the ease of use of the device. In the linear guide mechanism 600, the mounting plate, the guide base plate 620 and the top plate 350 are connected by bolts, which are firmly installed and easy to disassemble and maintain. The slider 640 on the guide body 630 cooperates with the screw rod 650, and under the drive of the second motor 610, can achieve precise linear displacement to meet different processing requirements. Overall, the device can flexibly adjust the linear displacement direction, position and angle of the guide body 630, thereby improving the adaptability of use.

[0035] The overall cross-section of the guide rail body 630 is an I-shaped configuration, while the overall cross-section of the inner lower end of the slider 640 is a convex-shaped configuration. The outer corners of the annular rail 100, slider 640, guide rail body 630, guide rail base plate 620, top plate 350, fixing bracket 500, and fixing plate 400 are all rounded. The overall cross-section of the guide rail is an I-shaped configuration. This design provides the guide rail with greater stability and load-bearing capacity during use, ensuring that the slider 640 slides smoothly on the guide rail. The overall cross-section of the inner lower end of the slider 640 is a convex-shaped configuration, matching the shape of the guide rail body 630. This further improves the stability of the slider 640 sliding on the guide rail and prevents it from falling out. The outer corners of the annular rail 100, slider 640, guide rail body 630, guide rail base plate 620, top plate 350, fixing frame 500 and fixing plate 400 are all set to be arc-shaped. On the one hand, this design reduces the possible harm to the operator during use and installation, thereby improving safety; on the other hand, it also makes the entire device more beautiful, while reducing the damage that may be caused to the corners due to stress concentration, thereby extending the service life of the device.

[0036] The principle of use and advantages are as follows: by setting up the rotating mechanism 200, the device can be operated by starting the first motor 224 during actual use. When the first motor 224 is running, it can directly and forcefully drive the gear 225 to rotate. Since the gear 225 is in a meshing transmission connection state with the internal gear ring 226 inside the annular groove 223 through the notch 222, at this time, as the gear 225 rotates, it can drive the gear ring to rotate. After the gear ring rotates, it can drive the slip ring 210 to slide smoothly on the inner side of the annular rail 100. By driving the slip ring 210 to rotate, it can drive the fixed block 230 on the top of the slip ring 210 to rotate. After the fixed block 230 rotates, it can assist in driving the linear guide mechanism 600 to rotate around the product to be processed. Such a design can greatly facilitate adaptation to various production and processing needs and provide strong support for efficient production.

[0037] By setting up the angle adjustment mechanism 300, the device can be used to start the electric push rod 360 to operate. After the electric push rod 360 is in operation, it can push the top plate 350, so that the top plate 350 drives the hinge seat 340 to rotate on the fixed column 330. At this time, by starting the electric push rod 360 on one side to extend and the electric push rod 360 on the other side to contract, the top plate 350 can be flexibly adjusted to rotate left and right. This design makes the device excellent in conveniently and flexibly adjusting the travel angle of the guide rail body 630, which can significantly improve the convenience of the overall use of the device. In addition, during the adjustment process, the second motor can be started to adjust the angle of the guide rail body 630. 610 is running, and the second motor 610 can drive the screw rod 650 inside the guide rail body 630 to rotate. Since the screw rod 650 and the slider 640 are in a threaded connection state, the slider 640 can be driven to perform linear displacement inside the guide rail body 630 by rotating the screw rod 650. It can be seen that the device as a whole can flexibly adjust the linear displacement during use, which greatly improves the convenience of using the device as a whole. It can be seen that the linear guide rail as a whole is convenient for flexible adjustment of the linear displacement direction, position and angle of the guide rail body 630, which can further improve the overall adaptability of the device as a whole, and provide a reliable solution for various complex processing needs.
