Description

Technical Field

[0001] This utility model relates to the field of automation equipment accessories technology, and in particular to slide rail assemblies for automated actuators. Background Technology

[0002] In the field of automation equipment technology, slide rail assemblies are one of the core components for achieving linear reciprocating motion in automated actuators. Their positioning accuracy, sliding stability, and durability directly affect the operating efficiency and service life of the actuators. However, most existing slide rail assemblies used in automated actuators employ a single guide rail structure, which is prone to problems such as offset and wobbling during sliding. The positioning accuracy is insufficient to meet the operational requirements of high-precision actuators. Furthermore, the positioning adjustment of the slider is cumbersome, lacking a convenient positioning structure, resulting in low adjustment efficiency and poor stability when the slider is stationary. Moreover, the lubrication methods of existing slide rail assemblies mostly rely on periodic manual application of lubricating oil, which cannot achieve continuous lubrication. After long-term use, the sliding resistance between the slider and the guide rail increases, accelerating component wear and increasing maintenance frequency and costs. Therefore, we propose a slide rail assembly for automated actuators. Utility Model Content

[0017] like Figure 1-5As shown, the slide rail assembly for an automated actuator proposed in this utility model includes a guide rail assembly 1 and a slider assembly 2. The guide rail assembly 1 includes a main guide rail 11, which is T-shaped. The top two sides of the main guide rail 11 are hook-shaped. A secondary guide rail 12 is provided on both sides of the main guide rail 11, and the secondary guide rail 12 is U-shaped. The mounting end of the secondary guide rail 12 is installed corresponding to one side of the main guide rail 11 and is fixedly connected to the main guide rail 11. Fixed end sleeves 13 are provided on the outer rings of both ends of the main guide rail 11 and the secondary guide rail 12. The mounting ends of the fixed end sleeves 13 are installed corresponding to the ends of the main guide rail 11 and the secondary guide rail 12. The inner rings of the fixed end sleeves 13 are tightly fitted to the outer circumferences of both ends of the main guide rail 11 and the secondary guide rail 12, respectively, for fixing. End sleeve 13 is fixedly connected to the main guide rail 11 and the secondary guide rail 12. The fixed end sleeve 13 ensures greater stability when the main guide rail 11 and the secondary guide rail 12 are assembled. A protective rubber pad 6 is provided on one side below the main guide rail 11 and the secondary guide rail 12. The mounting end of the protective rubber pad 6 is installed corresponding to the bottom side of the main guide rail 11 and the secondary guide rail 12. The protective rubber pad 6 is fixedly connected to the main guide rail 11 and the secondary guide rail 12. Both ends of the protective rubber pad 6 are respectively installed on the adjacent sides of two sets of fixed end sleeves 13. The protective rubber pad 6 provides protection to the bottom of the main guide rail 11 and the secondary guide rail 12, further improving their stability. Along the length direction of the main guide rail 11... Multiple sets of positioning holes 15 are evenly provided. These positioning holes 15 facilitate the operator's positioning of the slider assembly 2. The slider assembly 2 includes a main slider 21. The mounting end of the main slider 21 is installed corresponding to the upper side of the main guide rail 11. The bottom side of the main slider 21 interlocks with the hook-shaped side of the main guide rail 11, allowing the main slider 21 to slide smoothly along the main guide rail 11. The hook-shaped design at the top of the main guide rail 11 provides installation limitation and guidance for the main slider 21, ensuring stable sliding along the main guide rail 11. Auxiliary sliders 22 are provided on both sides below the main slider 21. The mounting end of the auxiliary slider 22 is installed corresponding to the lower side of the main slider 21, and the auxiliary slider 22 is fixedly connected to the main slider 21. The outer periphery of the auxiliary slider 22 is... The inner wall of the secondary guide rail 12 is correspondingly installed, and the secondary slider 22 is in close contact with the inner wall of the secondary guide rail 12. The secondary slider 22 is slidably connected to the secondary guide rail 12. Each set of secondary guide rails 12 has a guide rod 14 along its length on the inner wall. The two ends of the guide rod 14 are respectively installed on one side of the two sets of fixed end sleeves 13. The guide rod 14 is fixedly connected to the fixed end sleeves 13. The secondary slider 22 has a guide hole 7. The outer periphery of the guide rod 14 is in close contact with the inner wall of the guide hole 7. The secondary slider 22 is sleeved on the outside of the guide rod 14 through the guide hole 7. The mutual cooperation of the guide hole 7 and the guide rod 14 can limit and guide the movement of the main slider 21 through the secondary slider 22, thereby further improving the stability of the slider assembly 2 when it is in a sliding adjustment state on the guide rail assembly 1.This effectively avoids the offset and wobbling problems that are prone to occur with single-track guidance, ensuring the positioning accuracy and operational stability of the slider assembly 2 when sliding along the guide rail; Positioning components 3 are provided at both ends of the main slider 21. Each positioning component 3 includes an assembly block 31 located at one end of the main slider 21. The mounting end of the assembly block 31 is installed corresponding to one end of the main slider 21, and the assembly block 31 is fixedly connected to the main slider 21. The lower side of the assembly block 31 is installed corresponding to the upper side of the main guide rail 11, and the assembly block 31 is slidably connected to the main guide rail 11. A countersunk hole 32 is provided on the assembly block 31, and a countersunk positioning post 33 is provided in the countersunk hole 32. The countersunk positioning post 33 is adapted to both the countersunk hole 32 and the positioning hole 15, and is slidably connected to both the countersunk hole 32 and the positioning hole 15. The outer ring of the countersunk positioning post 33 is aligned with the inner ring of the countersunk hole 32. A return spring 34 is provided between the walls. One end of the return spring 34 is installed corresponding to one side of the countersunk positioning post 33, and the other end of the return spring 34 is installed corresponding to one side of the inner wall of the countersunk hole 32. The two ends of the return spring 34 are fixedly connected to one side of the countersunk positioning post 33 and the inner wall of the countersunk hole 32, respectively. The return spring 34 is sleeved on the outer ring of the countersunk positioning post 33. When the return spring 34 is in the initial state, the top end of the countersunk positioning post 33 passes through the countersunk hole 32 and is inserted into a set of positioning holes 15. The positioning component 3 facilitates the operator to quickly adjust and position the slider assembly 2 on the guide rail assembly 1, improves work efficiency, and ensures the stability of the slider assembly 2 when it is stationary. A lubrication assembly 4 is provided inside the main slider 21. The lubrication assembly 4 includes an oil reservoir 41 opened inside the main slider 21 and multiple sets of balls 42 on the main slider 21 corresponding to the side walls of the main guide rail 11 and the secondary guide rail 12. An oil injection hole 8 is opened at an inclined position at one end of the main slider 21 corresponding to the position of the oil reservoir 41. A plug 9 is provided at one end of the oil injection hole 8 on one side of the main slider 21. The plug 9 is slidably connected to the inner wall of the oil injection hole 8. The plug 9 can seal the oil injection hole 8. The oil injection hole 8 facilitates the operator to inject oil into the oil reservoir 41. In oil operation, ball grooves 10 are provided on the main slider 21 and the auxiliary slider 22 on one side near the main guide rail 11 and the auxiliary guide rail 12, respectively. Multiple sets of balls 42 are evenly laid along each set of ball grooves 10, and the balls 42 are rotatably connected to the ball grooves 10. Arc-shaped grooves are provided on the side walls of the main guide rail 11 and the auxiliary guide rail 12 at the positions corresponding to the ball grooves 10. The part of the ball 42 protruding from the ball groove 10 fits against the inner wall of the arc-shaped groove. The arc-shaped grooves can cooperate with the ball grooves 10 to ensure the stability of the balls 42. The multiple sets of balls 42 can reduce the slider's... The sliding resistance between component 2 and guide rail component 1 is considered. Multiple sets of oil leakage holes 43 are formed along the length of one side of the bottom of the oil reservoir 41. These holes 43 are arranged in a "V" shape and are connected to both the oil reservoir 41 and the ball groove 10. Each set of oil leakage holes 43 contains an oil-soaked cotton strip 44, which is tightly fitted to the inner wall of the hole. The "V" shape of the oil leakage holes 43 prevents the cotton strip 44 from falling into the ball groove 10 and damaging the balls. In the event of motion interference caused by 42, the top of the oil-soaked cotton strip 44 is located in the oil storage chamber 41, and the oil outlet end of the oil-soaked cotton strip 44 is located in the ball groove 10. The oil-soaked cotton strip 44 can slowly guide the lubricating oil in the oil storage chamber 41 through the oil leakage hole 43 to drip onto the ball 42 for rolling lubrication, ensuring the smoothness of multiple sets of balls 42 in the ball groove 10. The lubrication component 4 enables the device to achieve continuous lubrication, replacing the traditional manual periodic lubrication method, greatly reducing sliding resistance, reducing component wear, and extending the service life of the component. A mounting plate 5 is provided above the main slider 21. The mounting end of the mounting plate 5 is installed corresponding to the upper side of the main slider 21. The mounting end of the mounting plate 5 is fixedly connected to the main slider 21. Reinforcing ribs 16 are provided on both sides of the main slider 21 below the mounting plate 5. The reinforcing ribs 16 are triangular in shape. The two right-angled sides of the reinforcing ribs 16 are fixedly connected to the mounting plate 5 and the main slider 21 respectively. The setting of the reinforcing ribs 16 can improve the stability when the mounting plate 5 is assembled on the main slider 21. The setting of the mounting plate 5 makes it convenient for the operator to assemble the actuator with this device.

[0018] In this embodiment, the operator first assembles the secondary guide rail 12 on both sides of the main guide rail 11, and then assembles the slider assembly 2 with the positioning component 3 and the lubrication component 4 on the main guide rail 11. At this time, the guide rod 14 is inserted into the guide hole 7 on the secondary slider 22, and then the two sets of fixed end sleeves 13 are fixedly assembled with the two ends of the main guide rail 11 and the secondary guide rail 12, so that the two ends of the guide rod 14 are fixed with the fixed end sleeves 13, thereby completing the assembly operation of this device. When this device is used in conjunction with an automated actuator, the automated actuator is installed above the mounting plate 5. The operator then lifts the countersunk positioning pin 33 upwards, causing the countersunk positioning pin 33 to disengage from the pin position of the positioning hole 15, thereby allowing the slider assembly 2 to slide along the guide rail assembly 1. When the slider assembly 2 is in the sliding state, the main slider 21 slides along the main guide rail 11. At this time, the auxiliary slider 22 cooperates with the auxiliary guide rail 12 and the guide hole 7 to guide and limit the main slider 21. At the same time, the ball bearing 42 rotates to reduce the friction between the slider assembly 2 and the guide rail assembly 1. When the ball bearing 42 is rotating, the lubricating oil in the oil reservoir 41 drips slowly onto the ball bearing 42 through the oil-soaked cotton strip 44, ensuring the smooth rotation of the multiple sets of ball bearings 42. When the slider assembly 2 moves to the required position, the return spring 34 drives the countersunk positioning pin 33 to be inserted into the positioning hole 15 to position the slider assembly 2 under the action of the return spring.
