Description

Technical Field

[0001] This utility model belongs to the field of elevator technology, specifically relating to a connecting elevator. Background Technology

[0002] Connecting lifts are process connection devices in the machining industry. Their core function is to transfer workpieces between processing stations, equipment, or production lines at different heights. They feature a simple and robust structure, adaptable to the load-bearing requirements of various processing scenarios, and precisely adjustable lifting height to connect work nodes at different heights, such as machine tools, assembly lines, and warehouse racks. These machines are often equipped with conveyor tables or clamps, enabling automatic or semi-automatic lifting and translation of workpieces, reducing manual handling and preventing workpiece damage from bumps and knocks.

[0003] Existing shuttle lifts mostly use hydraulic rods for driving. Although they can lift the equipment, after long-term use, the control precision of shuttle lifts driven by hydraulic rods is easily affected by fluctuations in hydraulic pressure, making it difficult to achieve fine height adjustments. They are also prone to hydraulic leakage, which can cause the lifting platform to shift position and result in insufficient operational stability. In addition, the system structure composed of oil pipes, seals, etc. is complex, making later maintenance and disassembly cumbersome and costly. Utility Model Content

The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figures 1 to 4This utility model provides a connecting lift, including a mounting frame 2 fixedly installed on the side of a machine base 1. The mounting frame 2 is fixedly connected to the machine base 1 by bolts for easy maintenance. A conveyor belt 4 is installed on the side of the mounting frame 2 via a lifting assembly 3. The conveyor belt 4 is electrically connected to the machine base 1 and is used to transport components. A placement rack 5 is placed on the side of the conveyor belt 4 to support the items transported by the conveyor belt 4. The lifting assembly 3 includes a support platform 301 fixedly installed on the side of the mounting frame 2 away from the machine base 1. The support platform 301 is connected to a servo motor. The motor 303 is electrically connected to control the on / off state of the servo motor 303. A support frame 302 is fixedly installed on the top of the support platform 301. The support frame 302 is U-shaped and can provide extensive protection for the lead screw 304, thus preventing dust and moisture. The servo motor 303 is fixedly installed on the side of the support frame 302. The servo motor 303 provides high-precision control, thereby improving the flexibility and accuracy of the lifting assembly 3. The lead screw 304 is rotatably connected inside the support frame 302. The lead screw 304 cooperates with the threaded tube 308 and has a self-locking function. This ensures stable lifting and lowering of the threaded tube 308, avoiding errors. The lower end of the lead screw 304 and the output end of the servo motor 303 both penetrate the interior of the support platform 301 and are connected via a synchronous belt 305. The synchronous belt 305 guarantees the stability and synchronization of the servo motor 303's drive. The threaded tube 308 is sleeved on the side surface of the lead screw 304, and a U-shaped seat 307 is fixedly connected to the side surface of the threaded tube 308. A support base 306 is fixedly installed on the U-shaped seat 307. The conveyor belt 4 is fixedly installed on top of the support base 306 via a frame. The seat 306 is L-shaped and can fix the conveyor belt 4 from both the bottom and the sides, improving the stability and firmness of the installation of the conveyor belt 4. A pair of guide rails 309 are fixedly installed on the outside of the support frame 302 and on the mounting frame 2. A slider 310 is slidably connected to each of the guide rails 309. The slider 310 cooperates with the guide rails 309 to improve the smoothness of the conveyor belt 4 moving up and down. The slider 310 is fixedly connected to the support seat 306. The threaded tube 308 has a threaded hole inside, and the threaded tube 308 is threadedly connected to the lead screw 304 through the threaded hole.

[0018] In the lifting assembly 3, the support platform 301 is electrically connected to the servo motor 303 to control the start and stop of the servo motor 303. The output end of the servo motor 303 is connected to the lead screw 304 passing through the support platform 301 via the synchronous belt 305, driving the lead screw 304 to rotate inside the U-shaped support frame 302. The lead screw 304 is threadedly engaged with the threaded tube 308 through the threaded hole, driving the threaded tube 308 and the fixedly connected U-shaped seat 307 and L-shaped support seat 306 to move up and down, thereby driving the conveyor belt 4 fixed on the top of the support seat 306 to complete the lifting. At the same time, a pair of guide rails 309 on the outside of the mounting frame 2 are slidably engaged with the slider 310 fixed on the support seat 306 to assist the smooth movement of the conveyor belt 4. The placement frame 5 supports the items conveyed by the conveyor belt 4.

[0019] The lifting assembly 3 of this utility model, with the precise cooperation of the servo motor 303, synchronous belt 305, lead screw 304, and threaded tube 308, achieves control precision far exceeding that of hydraulic and pneumatic lifting systems affected by pressure / air pressure fluctuations, enabling fine height adjustments. The self-locking function of the lead screw 304 and threaded tube 308 eliminates the need for an additional locking mechanism. Combined with the sliding assistance of the guide rail 309 and slider 310, it effectively avoids positional deviations caused by hydraulic leakage and pneumatic depressurization, resulting in stronger operational stability. Furthermore, the components of the assembly are assembled using simple structures such as bolts. Compared to the oil pipes and seals of hydraulic systems and the complex piping of pneumatic systems, the connection between the mounting frame 2, the machine base 1, and the support base 306 is clear, making subsequent maintenance and disassembly more convenient and cost-effective.

[0020] Specifically, such as Figure 1 and Figure 3 As shown, the slider 310 has an "I"-shaped groove inside, which is the same as the cross-sectional shape of the support 306. The slider 310 slides on the support 306, which can improve the smoothness and stability of the conveyor belt 4 moving up and down, and can also withstand the longitudinal tension from the gravity of the conveyor belt 4, thereby effectively extending the service life of the device.

[0021] When the slider 310 slides on the guide rail 309, it synchronously follows the support seat 306 to drive the conveyor belt 4 to move up and down. At the same time, it directly bears the longitudinal tension generated by the gravity of the conveyor belt 4, forming a guide and force support for the movement of the conveyor belt 4.

[0022] Specifically, such as Figure 1 and Figure 2As shown, a pair of reinforcing plates 6 are fixedly connected inside the mounting bracket 2 and are arranged in parallel. A protective plate 7 is fixedly installed inside the support frame 302 and outside the lead screw 304. The protective plate 7 also penetrates the interior of the U-shaped seat 307. The installation of the reinforcing plate 6 can extend the service life of the mounting bracket 2 and improve the safety of the mounting bracket 2. The installation of the protective plate 7 can protect the lead screw 304 and prevent external dust and liquid from contacting the lead screw 304.

[0023] Specifically, such as Figure 4 As shown, a pair of symmetrically distributed gratings 8 are fixedly installed on the top of the conveyor belt 4, and the gratings 8 are electrically connected to the machine base 1.

[0024] The grating 8 can detect the presence or absence of objects on the conveyor belt 4, and then, after being controlled by the machine tool 1, it starts the servo motor 303 to drive the lead screw 304.

[0025] Specifically, such as Figure 1 As shown, an upper conveyor plate 501 is fixedly connected to the top of the placement rack 5, and a lower conveyor plate 502 is fixedly connected below the upper conveyor plate 501 and inside the placement rack 5; the arrangement of the lower conveyor plate 502 and the upper conveyor plate 501 is used to divert the objects.

[0026] Working principle and usage process of this utility model: When the operator is actually operating, the object can be placed on the conveyor belt 4. After the pair of symmetrical gratings 8 at the top of the conveyor belt 4 detects the object, they transmit the signal to the machine tool 1. The machine tool 1 then controls the servo motor 303, which is electrically connected to the support platform 301, to start. Servo motor 303 drives lead screw 304 to rotate synchronously via synchronous belt 305. Lead screw 304 engages with threaded tube 308 through threaded hole, driving threaded tube 308 and fixedly connected U-shaped seat 307 and L-shaped support seat 306 to move up and down, thereby driving the conveyor belt 4 fixed on top of support seat 306 to achieve precise lifting and lowering. During this process, a pair of guide rails 309 on the outside of mounting frame 2 slide with slider 310 fixed to support seat 306, ensuring the smooth up and down movement of conveyor belt 4 and allowing slider 310 to bear the longitudinal tension generated by the gravity of conveyor belt 4 to extend the service life of the device. The protective plate 7 inside support frame 302 prevents dust and liquid from contacting lead screw 304, and a pair of upper and lower parallel reinforcing plates 6 inside mounting frame 2 improve the safety and service life of mounting frame 2. Once the conveyor belt 4 is raised to the appropriate height, the self-locking function of the lead screw 304 and the threaded tube 308 prevents positional deviation. The conveyor belt 4 then begins to transport objects. The upper conveyor plate 501 and the lower conveyor plate 502 of the placement frame 5 provide diversion support for the objects. The entire connecting conveying process achieves fine height adjustment through the precise cooperation of the servo motor 303 and the lead screw 304. The operation is stable and there is no risk of hydraulic leakage or pneumatic pressure relief. During subsequent maintenance, since the mounting frame 2 is fixed to the machine base 1 with bolts, the assembly structure of each component is simple, and disassembly and maintenance are convenient and efficient.

[0027] 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.
