Description

Technical Field

[0001] This utility model relates to the field of guiding and lifting technology, and in particular to a guiding and lifting component. Background Technology

[0002] A guide lifting assembly is a mechanical device used to achieve linear motion and precise positioning, widely used in automation equipment, industrial machinery, lifting systems, and other fields. Its core function is to provide stable guidance and lifting for moving parts, ensuring the smoothness, accuracy, and reliability of the motion process.

[0003] The guide lifting assembly mainly consists of guide rails, sliders, transmission mechanisms such as lead screws and synchronous belts, and drive motors. During operation, the motor converts rotary motion into linear motion through the transmission mechanism (such as lead screws), driving the load to move. The movement of the load is ensured by the motor driving the lead screws and other transmission components.

[0004] In traditional guide lifting components, the transmission mechanism often uses a motor-lead screw combination to achieve linear drive. However, this method has certain limitations. Lead screw transmission is susceptible to wear and backlash, which may lead to a decrease in positioning accuracy after long-term use. Vibration and noise may also occur during high-speed movement, affecting the stability of the system. Therefore, a guide lifting component is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1 to 2 This utility model provides an embodiment of a guide lifting assembly, including a base plate 1, which provides an overall support foundation and ensures the installation accuracy of each component. A fixed plate seat 2 is fixedly connected to the top of the base plate 1, serving as the installation reference for the motor 3 and the lead screw 5, ensuring the stability of the transmission system. The motor 3 is installed on one side of the fixed plate seat 2, converting electrical energy into mechanical energy to provide a power source for the lifting action. The drive end of the motor 3 is connected to the lead screw 5 via a coupling 4, achieving a flexible connection between the motor 3 and the lead screw 5 to compensate for installation errors. The lead screw 5 is fixedly connected and is the core transmission component that converts rotational motion into linear motion. The lead screw 5 is externally threaded to a base 6, which converts the rotational force of the lead screw 5 into linear thrust, driving the lifting frame to move.

[0028] The top of the base plate 1 is fixedly connected to the guide rail 17, which provides a precise linear motion trajectory for the lifting frame. The top of the guide rail 17 is slidably connected to the lifting frame assembly, which is the main body for lifting and lowering the load. Roller bearings 8 are installed on both sides of the lifting frame assembly. The rolling friction reduces the motion resistance and improves the motion stability. The roller bearings 8 and the guide rail 17 form a rolling fit. The V-groove structure enhances the guiding accuracy and prevents derailment. The roller bearings 8 are double-row angular contact bearings, which can bear radial and axial loads at the same time, thereby improving the load-bearing capacity.

[0029] The outer surface of the roller bearing 8 is adapted to the V-groove of the guide rail 17. The self-centering property of the V-shaped surface ensures the consistency of the motion trajectory. The top of the base plate 1 is fixedly connected to the guide shaft 15, which serves as the first reference axis of the adjustment mechanism. The top of the base plate 1 is fixedly connected to the guide shaft 16, which together with the guide shaft 15 forms the dual-axis guide frame of the adjustment system. The outer surface of the guide shaft 15 is fitted with an adjustment block 12, which is a key adjustment component that dynamically connects the lifting frame and the guide shaft. The outer surface of the guide shaft 16 is fitted with an adjustment rod 13, which works in conjunction with the adjustment block 12 to achieve the gap compensation function. The adjustment block 12 and the adjustment rod 13 are connected by an adjustment screw 18, which provides precise gap adjustment and locking functions. The outer thread of the adjustment screw 18 is connected to a large nut 14 to ensure that the position is reliably locked after adjustment.

[0030] The lifting frame assembly includes a symmetrically arranged left lifting frame 9 and a right lifting frame 10. The double-frame structure enhances overall rigidity and balances the force. The left and right lifting frames 9 and 10 have pin holes on their exteriors, providing an installation interface for hinged connections. The base 6 has a pin 7 on its exterior, which serves as an intermediary component for transmitting the thrust of the lead screw 5 to the lifting frame. The pin 7 passes through the pin hole, forming a movable connection to accommodate position changes during adjustment. The upper and lower ends of the left lifting frame 9 are respectively connected to the adjusting block 12 and the base 6 via a double hinge point design using a second pin 11. The upper and lower ends of the right lifting frame 10 are respectively connected to the second pin 11, forming a parallelogram mechanism to ensure synchronous movement. The right lifting frame 10 is also hinged to the adjusting block 12 and the base 6. The adjusting screw 18 is a graduated fine-tuning screw to realize the spacing adjustment function.

[0031] The two ends of the adjusting screw 18 are threaded to the adjusting block 12 and the adjusting rod 13 respectively, forming an adjustable rigid connection. The inner hole of the adjusting block 12 is equipped with a guide copper sleeve 19 to reduce the friction of the guide shaft and have self-lubricating properties. The inner hole of the adjusting rod 13 is equipped with a guide copper sleeve 20, which together with the guide copper sleeve 19 ensures the smooth movement of the adjusting mechanism. The inner walls of the guide copper sleeve 19 and the guide copper sleeve 20 are provided with spiral oil grooves to achieve long-term maintenance and uniform distribution of lubricating oil.

[0032] Working principle: The guide lifting assembly is driven by motor 3 to rotate the lead screw 5, which in turn drives the base 6 to move axially along the lead screw 5. Since the base 6 is connected to the left 9 and right 10 of the lifting frame through pin 7, the linear motion of the base 6 pushes the lifting frame assembly to move up and down along the guide rail 17. The roller bearing 8 rolls in the V-groove of the guide rail 17 to ensure that the lifting frame moves smoothly and guides accurately, while bearing radial and axial loads and preventing off-center loading and jamming.

[0033] Adjusting block 12 and adjusting rod 13 are respectively sleeved on guide shaft 15 and guide shaft 2 16, and connected by adjusting screw 18 to form a rigid structure with adjustable spacing. When the lifting frame moves, adjusting block 12 and adjusting rod 13 slide along the guide shaft with the assistance of guide copper sleeve 19 and guide copper sleeve 20 to ensure smooth movement. If there is a deviation between the guide shaft spacing and the adjusting mechanism, the hinge design of pin 2 11 allows for slight swing to compensate for installation errors and avoid movement interference. The adjusting screw 18 with scale fine adjustment can accurately adjust the spacing between adjusting block 12 and adjusting rod 13, and is locked with large nut 14 to ensure structural stability. The entire system achieves high-precision, low-friction lifting movement through the coordinated action of motor 3 drive, lead screw 5 transmission, roller guide and hinge compensation.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
