[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0025] For examples, please refer to Figures 1-4 This utility model provides a technical solution:
[0026] A precision ball bearing lift suitable for low-profile environments includes a main body 1, a limit bearing assembly 2 fixedly connected to the top of the main body 1, and a ball bearing lift assembly 3 fixedly connected to the side of the limit bearing assembly 2.
[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the limiting bearing assembly 2 includes a column 201, a side plate 202 fixedly connected to the side of the column 201, a first bracket 203 fixedly connected to the side of the column 201, and a first limit switch 204 installed on the side of the first bracket 203. The ball lifting assembly 3 includes a mounting plate 301, a support plate 302 fixedly connected to the top of the mounting plate 301, a servo motor 303 installed on the top of the support plate 302, a lead screw 304 fixedly connected to the output end of the servo motor 303, and a ball screw 304 threadedly connected to the bottom of the lead screw 304. The ball thread block 305 has a connecting plate 308 fixedly connected to its side. Driven by the servo motor 303, the ball thread block 305 moves on the lead screw 304 and, in conjunction with the slide rail 306 and the slider 307, can lift and lower the loading box 309. The movement accuracy of the ball thread block 305 on the lead screw 304 can reach the micron level. Combined with the guiding effect of the slide rail 306 and the slider 307, it can ensure that the metal plate maintains linear motion during the movement, thereby achieving high-precision positioning.
[0028] The system includes two side plates 202, with a second bracket 205 fixedly connected to the side of each side plate 202. A second limit switch 206 is installed on the side of the second bracket 205. A slide rail 306 is fixedly connected to the side of the mounting plate 301, and a slider 307 is slidably connected to the side of the slide rail 306. The slider 307 is fixedly connected to the connecting plate 308. There are two slide rails 306 and four sliders 307. A bearing seat 310 is fixedly connected to the side of the mounting plate 301, and a lead screw 304 extends into the interior of the bearing seat 310. A cargo box 309 is fixedly connected to the side of the connecting plate 308. By using the first limit switch 204 and the second limit switch 206, when the lifting mechanism reaches the preset upper or lower limit, the corresponding limit switch will activate. After receiving the limit signal, the controller will immediately stop the operation of the servo motor 303, which can effectively prevent the lifting platform from exceeding the safe range and improve the safety and reliability of the equipment.
[0029] In this embodiment, as Figure 1 and Figure 4As shown, the main body 1 includes a base plate 101 made of stainless steel. A reinforcing triangular block 102 is fixedly connected to the top of the base plate 101. Several reinforcing triangular blocks 102 are provided. Welded plates 103 are fixedly connected to the sides of the reinforcing triangular blocks 102. Several welded plates 103 are provided. The triangular structure has extremely high stability and is one of the most stable structures in geometry. By embedding the reinforcing triangular blocks 102 into the base, the overall stability of the base can be significantly enhanced, enabling it to maintain a more stable support state when bearing the weight of the lifting platform and external impact forces. During the lifting process, the movement of the lifting platform will generate a certain amount of vibration and sway. The reinforcing triangular blocks 102 can effectively disperse and absorb these vibrations, reducing the swaying of the base and thus improving the overall operational stability of the lifting machine, ensuring the smoothness of the lifting process.
[0030] The working process of this utility model is as follows: A precision-controlled ball bearing lift designed for low-ceiling environments utilizes a servo motor 303 to drive a ball thread block 305 to move on a lead screw 304. This, in conjunction with a slide rail 306 and a slider 307, lifts and lowers the cargo box 309, ensuring smoothness and control precision during the lifting process. The servo motor 303 receives external control signals through a controller to achieve precise control of the lifting mechanism. It can adjust the speed and direction of the servo motor 303 in real time according to preset lifting height and speed requirements, thereby achieving precise control of the lifting mechanism. The first limit switch 204 and the second limit switch 206 activate when the lifting platform reaches a preset upper or lower limit. Upon receiving the limit signal, the controller immediately stops the servo motor 303 to prevent the lifting mechanism from exceeding safe limits.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
