Description

Technical Field

[0001] This application relates to the technical field of linear slides, and in particular to an electric linear slide. Background Art

[0002] As an important mechanical device, a linear guide rail is mainly used to guide an object to perform precise linear reciprocating motion. It mainly consists of two key parts: a rail and a slider. The rail is usually a long strip-shaped component with extremely high precision, and its surface is processed extremely precisely, which can provide extremely accurate linear guidance for the movement of the object. The slider, as a moving component matching the rail, generally contains rolling elements such as balls or rollers inside. It is the existence of these rolling elements that transforms the friction between the slider and the rail into rolling friction. Compared with traditional sliding friction, rolling friction reduces the frictional force, enabling the slider to move extremely smoothly and smoothly on the rail. The linear guide rail has a strong load-bearing capacity and can withstand certain radial and axial loads. Even under high loads, it can still maintain high-precision linear motion. For this reason, linear guide rails are widely used in many fields with extremely high requirements for motion precision and stability, such as numerical control machine tools, automation equipment, robots, etc., and have become one of the key components for realizing precise linear motion control;

[0003] However, in the current prior art, linear guide rails usually have certain limitations. They often can only perform unidirectional forward and backward displacements. In actual use, if multi-directional adjustment displacements are required, usually multiple linear slide devices need to be set up for adjustment. It can be seen that the linear guide rails in the prior art lack the function of multi-directional and multi-angle adjustment by a single set of linear guide rails. In the application process, this limitation greatly restricts its overall use and cannot be applied to more flexible mechanical systems. Therefore, in order to meet the requirements of modern mechanical systems for flexibility and versatility, it is urgent to improve and innovate the existing linear guide rails.

[0031] The angle adjustment assembly 26 includes a concave frame 261. The concave frame 261 is fixedly installed on the top of the turntable 230. A mounting seat 262 is rotatably connected to the inner side of the concave frame 261. A top plate 263 is fixedly installed on the top of the mounting seat 262. The top of the top plate 263 is fixedly connected to the bottom of the linear displacement mechanism 300. Electric push rods 264 are hinged to both sides of the top plate 263. The bottoms of the electric push rods 264 are hinged to both sides of the turntable 230. The fixed plate 210 in the adjustment mechanism 200 is firmly installed on the top of the substrate 100, providing stable support for the first motor 220. The first motor 220 drives the turntable 230 to rotate, enabling the connected linear displacement mechanism 300 to change the displacement direction, greatly improving the flexibility and adaptability of the device. The concave frame 261 of the angle adjustment assembly 26 is fixed on the top of the turntable 230. The mounting seat 262 is rotatably connected within the concave frame 261. The top plate 263 on the top is firmly connected to the linear displacement mechanism 300. The electric push rods 264 on both sides of the top plate 263 are hinged to the turntable 230, and the rotation angle of the mounting seat 262 can be precisely controlled, thereby realizing flexible adjustment of the angle of the linear displacement mechanism 300. This design enables the electric linear slide to meet the diverse requirements for the linear displacement direction and angle in different working scenarios.

[0032] Support brackets 240 are fixedly installed at equal intervals on the bottom of the turntable 230. The side shape of the support brackets 240 is L-shaped. A rolling ball 25 is rotatably connected to the outer side of the bottom of the support brackets 240. The bottom of the rolling ball 25 is in fit connection with the top of the substrate 100. Mounting holes 400 are provided at the four corners of the substrate 100, and the mounting holes 400 are countersunk holes. The support brackets 240 with an L-shaped side at equal intervals on the bottom of the turntable 230 provide a stable support structure for the turntable 230, enhancing the stability of the entire device during operation. The rolling ball 25 rotatably connected to the outer side of the bottom of the support brackets 240 is in fit connection with the top of the substrate 100 when the turntable 230 rotates, reducing the frictional resistance and making the rotation of the turntable 230 smoother. At the same time, it can support and reinforce the turntable 230 in cooperation with the support brackets 240, improving the operation efficiency and precision of the device. The countersunk mounting holes 400 provided at the four corners of the substrate 100 facilitate the fixed installation of the device, ensuring that the device does not displace during operation, further improving the stability and reliability of the device, and enabling the electric linear slide to better adapt to various working environments.

[0033] The linear displacement mechanism 300 includes a guide rail 310, which is fixedly mounted on the top of the top plate 263. One end of the guide rail 310 is fixedly connected to the second motor 320. The guide rail 310 is internally rotatably connected to the lead screw 330. The outer surface of the lead screw 330 is threadedly connected to the slider 340. The output end of the second motor 320 is fixedly connected to one end of the lead screw 330. A fixing plate 350 is fixedly mounted on the top of the slider 340. The fixing holes 360 are provided at the four corners of the fixing plate 350. The side shape of the slider 340 is convex, and the cross-sectional shape of the internal cavity of the guide rail 310 is also set to be convex. A tungsten steel alloy wear-resistant gasket is fixedly connected to the outer surface of the slider 340. The outer surface corners of the substrate 100, the guide rail 310, the top plate 263 and the concave frame 261 are all set to be arc-shaped. The guide rail 310 is fixedly mounted on the top of the top plate 263, and the connection is firm, providing a stable track for the movement of the slider 340. The second motor 320 provides power for the screw rod 330, so that the screw rod 330 can accurately drive the slider 340 connected by thread to move in the guide rail 310 to achieve precise linear displacement. The fixing plate 350 on the top of the slider 340 is convenient for connecting to external equipment through the fixing hole 360. The cross-section of the internal cavity of the slider 340 and the guide rail 310 are both convex. This design ensures the stability of the slider 340 during movement and prevents it from detaching from the guide rail 310. The tungsten steel alloy wear-resistant gasket on the outer surface of the slider 340 enhances the wear resistance of the slider 340 and extends the service life of the device. In addition, the outer surface corners of the substrate 100, the guide rail 310, the top plate 263 and the concave frame 261 are set to be arc-shaped, which improves the safety of use and avoids accidental collision and injury to personnel, and also makes the appearance of the device more smooth and beautiful.

[0034] The use principle and advantages are as follows: by setting the adjustment mechanism 200, the device can show excellent performance and flexibility during use. First, the first motor 220 can be started to drive the turntable 230 to rotate. When the first motor 220 drives the turntable 230 to rotate, it can further drive the linear displacement mechanism 300 to rotate together. During this process, the second motor 320 is started to run, and the second motor 320 drives the screw rod 330 to rotate. The rotation of the screw rod 330 will drive the slider 340 to slide on the inner side of the guide rail 310. The lateral sliding of the slider 340 can not only assist in adjusting its own lateral sliding displacement, but also provide strong support for the flexible adjustment of the entire device. Through the adjustment and sliding of the slider 340, flexible control of the device can be achieved.

[0035] At the same time, the design of using the first motor 220 to drive the turntable 230 to rotate is of great significance. The rotation of the turntable 230 can cleverly change the linear displacement direction of the linear displacement mechanism 300. As the turntable 230 rotates, the slider 340 can be displaced in any direction, greatly expanding the movement range and flexibility of the device.

[0036] The angle adjustment component 26 is provided to add more advantages to the device during use. During use of the device, the two electric push rods 264 play a key role. One electric push rod 264 can be started to run while the other electric push rod 264 is retracted. Such an operation can flexibly adjust the rotation of the mounting seat 262 on the inner side of the concave frame 261. This design enables the device to flexibly adjust the rotation angle of the top plate 263 during use, thereby flexibly adjusting the angle of the linear displacement mechanism 300 on the top of the top plate 263.

[0037] In summary, the device as a whole can flexibly adjust the sliding direction and the sliding angle direction of the slider 340 during use, which enhances the adaptability of the device in mechanical equipment. It can play an excellent role whether in complex mechanical systems or in situations with extremely high requirements for motion accuracy and flexibility. The overall adaptability of the linear slide is stronger and its application prospects are broader.
