Technical Field

[0001] The present invention relates to the technical field of guide rails, and specifically to an anti-derailment annular guide rail with a follow-up guiding structure. Background Art

[0002] In industrial automation production and many precision equipment operation scenarios, as a key component for realizing circular motion, the annular guide rail has the advantages of high precision, strong load capacity, stable operation, compact structure, flexible installation method, etc. It can effectively improve production efficiency and reduce floor space. It can provide a stable motion trajectory for the slider and is widely used in fields such as automated production lines, logistics sorting systems, and precision inspection equipment. However, during actual operation, the annular guide rail faces many challenges, among which the derailment problem seriously affects the normal operation of the equipment and production efficiency. Traditional annular guide rails have certain limitations when dealing with complex working conditions, such as:

[0003] In an automated production line, as the production beat accelerates, the slider frequently accelerates and decelerates. At this time, the inertial force received by the slider changes greatly, making it easy to deviate from the established track. And in some application scenarios that need to carry workpieces of different weights or irregular shapes, when the slider runs on the annular guide rail, the pressures borne by each part are inconsistent, which in turn causes the slider to tilt and shift, ultimately leading to derailment.

[0004] In view of the above problems, there is an urgent need to innovate and design on the basis of the original annular guide rail structure. Summary of the Invention

[0005] The purpose of the present invention is to provide an anti-derailment annular guide rail with a follow-up guiding structure to solve the problems mentioned in the above background art. In an automated production line, as the production beat accelerates, the inertial force received by the slider changes greatly, making it easy to deviate from the established track. And in some application scenarios that need to carry workpieces of different weights or irregular shapes, when the slider runs on the annular guide rail, the pressures borne by each part are inconsistent, which in turn causes the slider to tilt and shift.

[0006] To achieve the above purpose, the present invention provides the following technical solution: An anti-derailment annular guide rail with a follow-up guiding structure, including a guide rail support, which serves as the main supporting base of the annular track. Two connecting roller rods are rotatably connected to the upper end of the guide rail support, and the connecting roller rods penetrate and are fixedly connected to a driving gear in a circular shape. The tooth blocks of the driving gear are meshed with an inner transmission belt. The above structure constitutes the main structure of the transmission of the annular guide rail.

[0007] The inner drive belt and the outer drive belt are sleeved and connected, and the outer drive belt is integrally arranged in an L shape. The bottom end of the outer drive belt is slidably connected to the bottom end of the inner drive belt, and the outer drive belt and the inner drive belt together form a U-shaped guide rail structure. The bottom end of the outer drive belt abuts against the surface of the auxiliary bracket, and the auxiliary bracket is fixedly installed on the upper end surface of the guide rail bracket. The auxiliary bracket is integrally made of insulating rubber, and anti-slip protrusions are arranged on the contact surface between the upper end surface of the auxiliary bracket and the outer drive belt;

[0008] An electric drive slide rail is embedded and installed on the upper end surface of the outer drive belt, and the electric drive slide rail is electrically connected to the power-on contact. The power-on contact is installed on the side wall surface of the connection slider through bolts, and the connection slider is the main structure in the tooling slider assembly;

[0009] A positioning airbag frame is installed on one side of the connection slider through bolts, and an auxiliary block is installed on the other side of the connection slider through bolts. A rubber roller is rotatably connected to the inner wall surface of the auxiliary block, and the rubber roller of the auxiliary block is in rolling contact with the outer wall surface of the outer drive belt. There is a tooling support bracket above the connection slider, and a magnetic connection buckle is fixedly installed in the tooling support bracket.

[0010] Adopting the above technical solution, a circular guide rail is formed by the guide rail bracket, the connecting roller rod, the driving gear and the inner drive belt, and then the electric drive slide rail and the power-on contact are used to supply power to the tooling slider assembly. With the cooperation of the auxiliary block, the positioning airbag frame and other components to ensure the operation of the slider, the overall stable anti-derailment operation is realized.

[0011] Preferably, one anti-slip ring is sleeved and installed on the upper and lower tooth blocks of the driving gear respectively, and the anti-slip ring and the driving gear are arranged in a concentric circle.

[0012] Adopting the above technical solution, the anti-slip ring and the driving gear are arranged in a concentric circle and sleeved on the upper and lower tooth blocks, which can increase the friction between the driving gear and the inner drive belt, prevent transmission slippage, and improve the stability of the transmission process.

[0013] Preferably, the anti-slip ring is slidably connected to the upper and lower two chutes opened on the inner wall surface of the inner drive belt, and tooth blocks meshing with the driving gear are arranged on the inner wall surface of the inner drive belt.

[0014] Adopting the above technical solution, the anti-slip ring is slidably connected to the inner wall chute of the inner drive belt, which not only helps the inner drive belt to maintain the correct movement track and avoid deviation, but also further ensures the accuracy of the meshing transmission between the driving gear and the inner drive belt.

[0015] Preferably, the cable of the electric drive slide rail penetrates through the auxiliary bracket, the power supply metal belt of the electric drive slide rail is connected to the metal contact of the power-on contact, and the power-on contact supplies power to the components in the tooling slider assembly.

[0016] With the above technical solution, the connection method between the electric drive slide rail and the energized contact provides a stable power supply for the components within the tooling slider assembly, ensuring the normal operation of each component.

[0017] Preferably, the auxiliary block and the positioning airbag frame are symmetrically installed on both sides of the connecting slider, and the connecting slider, the auxiliary block, and the positioning airbag frame are assembled together to form a U-shaped block structure with the opening facing downward, and this U-shaped block structure with the opening facing downward is slidably connected to the upper end of the outer transmission belt.

[0018] With the above technical solution, the auxiliary block and the positioning airbag frame are symmetrically installed and form a U-shaped block structure with the connecting slider, which restricts and guides from multiple directions, enhances the anti-derailment ability, and ensures the stable sliding of the connecting slider along the outer transmission belt.

[0019] Preferably, airbags made of insulating rubber are provided on both sides of the positioning airbag frame, and the positioning airbag frame is fixed to the outer wall surface of the inner transmission belt by bolts, and the positioning airbag frame is installed on the outer wall surface of the inner transmission belt in a vertical state.

[0020] With the above technical solution, the airbags on both sides of the positioning airbag frame can buffer external force impacts, are vertically fixed to the outer wall surface of the inner transmission belt by bolts, limit the excessive displacement of the connecting slider in the vertical direction, and effectively prevent derailment.

[0021] Preferably, the tooling slider assembly further includes a follower auxiliary slide frame, a micro ball screw, and a buffer slide rail, and a follower auxiliary slide frame is installed at the upper end of the connecting slider.

[0022] With the above technical solution, the follower auxiliary slide frame, the micro ball screw, and the buffer slide rail expand the functions of the tooling slider assembly, providing the possibility for realizing more complex motion control and working requirements.

[0023] Preferably, the follower auxiliary slide frame is rotatably connected to both ends of the micro ball screw, and the follower auxiliary slide frame and the micro ball screw form a tooling structure.

[0024] With the above technical solution, the follower auxiliary slide frame is rotatably connected to the micro ball screw and forms a tooling structure, which can realize relatively flexible motion adjustment and meet the requirements for adjusting the position and posture of the tooling under different working conditions.

[0025] Preferably, the slide rod in the follower auxiliary slide frame is slidably connected through the slide table of the micro ball screw, and a buffer slide rail is installed at the upper end of the slide table of the micro ball screw.

[0027] Preferably, the buffer slide rail is slidably connected to the bottom end of the tooling support bracket, and the sliding direction of the buffer slide rail is perpendicular to the displacement direction of the micro ball screw stage.

[0028] With the above technical solution, the buffer slide rail is slidably connected to the tooling support bracket and the direction is perpendicular to the displacement direction of the micro ball screw stage, which can better play a buffering role and at the same time realize the fine adjustment of the tooling support bracket in the vertical direction, improving the stability.

[0029] Compared with the prior art, the beneficial effects of the present invention are: the anti-derailment annular guide rail provided with a follow-up guiding structure:

[0030] 1. The entire annular guide rail is composed of a main transmission structure including a guide rail bracket, a connecting roller rod, a driving gear and an inner transmission belt, which can realize the stable circular transmission of the annular guide rail. The meshing connection between the driving gear and the inner transmission belt, combined with the sliding connection between the anti-slip ring and the inner wall chute of the inner transmission belt, effectively increases the friction force during the transmission process, prevents the occurrence of slipping phenomenon, ensures the accuracy and stability of the transmission, and guarantees the smooth operation of the annular guide rail system;

[0031] 2. When the whole annular guide rail rotates to drive the tooling slider assembly to move, the rubber rollers rotatably connected to the inner wall of the auxiliary block rollingly contact the outer wall of the outer transmission belt, following the guide rail track in real time, playing a good guiding role, enabling the connecting slider to stably run along the annular guide rail in the horizontal direction, effectively preventing it from randomly deviating. The insulating rubber air bags on both sides of the positioning air bag frame can absorb energy through deformation and give a reverse force when the connecting slider is impacted or has a tendency to derail. At the same time, it is vertically installed on the outer wall surface of the inner transmission belt, restricting the excessive displacement of the connecting slider in the vertical direction from the side. Further, the U-shaped block structure with an open bottom composed of the connecting slider, the auxiliary block and the positioning air bag frame is slidably connected to the upper end of the outer transmission belt, restraining and guiding the connecting slider from multiple directions, enhancing the anti-derailment performance and effectively reducing the derailment risk;

[0032] 3. The follow-up auxiliary carriage in the tooling slider assembly is rotatably connected to both ends of the micro ball screw. Through the principle of screw drive, the micro ball screw can drive its slide to move, realizing the precise position adjustment of the tooling support bracket within a certain range. When the tooling slider assembly is impacted, the buffer slide rail can absorb the impact energy and at the same time realize the fine adjustment of the tooling support bracket in the vertical direction, ensuring the stability of the items carried on the tooling support bracket and improving the reliability of the equipment operation;

[0033] 4. Since the electric drive slide rail is embedded in the upper end face of the outer transmission belt and is connected to the energized contact installed on the side wall surface of the connection slider through a cable passing through the auxiliary bracket to supply power to the components inside the tooling slider assembly, the structural connection of the power supply method is stable, which can provide reliable power support for each component inside the tooling slider assembly to ensure its normal operation. At the same time, the auxiliary bracket made of insulating rubber plays a certain insulation and protection role, improving the safety of equipment operation. Brief Description of the Drawings

[0051] Combined with the Figures 1 - 10As shown, when the guide rail bracket 1 is installed, it is installed horizontally, and the connecting roller rod 2 rotating inside the guide rail bracket 1 is directly docked with the output end of the driving part. A bearing is used at the connection between the guide rail bracket 1 and the connecting roller rod 2 to achieve rotation. Then, the driving gear 3 is fixedly installed on the connecting roller rod 2 by means of interference fit or key connection, as Figures 1 - 5 shown, to ensure the coaxiality and connection firmness between the driving gear 3 and the connecting roller rod 2. Anti-slip rings 4 are respectively sleeved on the upper and lower tooth blocks of the driving gear 3 to ensure that the anti-slip rings 4 are concentric with the driving gear 3 and can slide well with the upper and lower two chutes opened on the inner wall surface of the inner transmission belt 5;

[0052] The inner transmission belt 5 is installed on the driving gear 3 to ensure that the tooth blocks on the inner wall of the inner transmission belt 5 are correctly meshed with the tooth blocks of the driving gear 3. The outer transmission belt 6 is sleeved on the inner transmission belt 5 to make the bottom end of the outer transmission belt 6 slide well with the bottom end of the inner transmission belt 5, forming a U-shaped guide rail structure. At the same time, an auxiliary bracket 7 is installed and fixed on the upper end surface of the guide rail bracket 1, and the bottom end of the outer transmission belt 6 abuts against the surface of the auxiliary bracket 7. The anti-slip protrusions on the auxiliary bracket 7 are in close contact with the outer transmission belt 6. The electric drive slide rail 8 is embedded and installed on the upper end surface of the outer transmission belt 6 according to the designed position, and the cable of the electric drive slide rail 8 passes through the auxiliary bracket 7 for reasonable wiring, as Figures 3 - 5 shown. On the side wall surface of the connection slider 1001, a power-on contact 9 is accurately installed by bolts to ensure reliable connection between the power supply metal belt of the electric drive slide rail 8 and the metal contact of the power-on contact 9, so that the electric drive slide rail 8 provides reliable power support for each component in the tooling slider assembly 10 to ensure its normal operation. At the same time, the auxiliary bracket 7 made of insulating rubber can also play a certain insulating and protective role, improving the safety of equipment operation;

[0053] One side of the connection slider 1001 is installed with a positioning airbag bracket 1003 by bolts, and the other side of the connection slider 1001 is installed with an auxiliary block 1002 by bolts. A rubber roller is rotatably connected to the inner wall surface of the auxiliary block 1002, and the rubber roller of the auxiliary block 1002 is in rolling contact with the outer wall surface of the outer transmission belt 6. The auxiliary block 1002 and the positioning airbag bracket 1003 are symmetrically installed on both sides of the connection slider 1001, and the connection slider 1001, the auxiliary block 1002 and the positioning airbag bracket 1003 are assembled together to form a U-shaped block structure with the opening facing downwards. And this U-shaped block with the opening facing downwards slides on the upper end of the outer transmission belt 6. Insulating rubber-made airbags are arranged on both sides of the positioning airbag bracket 1003, and the positioning airbag bracket 1003 is fixed to the outer wall surface of the inner transmission belt 5 by bolts, and the positioning airbag bracket 1003 is installed on the outer wall surface of the inner transmission belt 5 in a vertical state. There is a tooling support bracket 1007 above the connection slider 1001, and a magnetic connection buckle 1008 is fixedly installed in the tooling support bracket 1007;

[0054] The tooling slider assembly 10 further includes a follower auxiliary carriage 1004, a micro ball screw 1005, and a buffer slide rail 1006. A follower auxiliary carriage 1004 is installed at the upper end of the connecting slider 1001. The two ends of the follower auxiliary carriage 1004 are rotatably connected to the micro ball screw 1005, and the follower auxiliary carriage 1004 and the micro ball screw 1005 form a tooling structure. The slide bar in the follower auxiliary carriage 1004 is slidably connected through the slide table of the micro ball screw 1005. A buffer slide rail 1006 is installed at the upper end of the slide table of the micro ball screw 1005. The buffer slide rail 1006 is slidably connected to the bottom end of the tooling support bracket 1007, and the sliding direction of the buffer slide rail 1006 is perpendicular to the displacement direction of the slide table of the micro ball screw 1005.

[0055] Combined with the attached drawings of the specification Figures 1 - 10 As shown, the auxiliary block 1002 is installed on one side of the connecting slider 1001 by bolts, ensuring that the rubber rollers on the inner wall of the auxiliary block 1002 can rotate flexibly and maintain good rolling contact with the outer wall surface of the outer transmission belt 6, providing stable guidance when the rubber rollers on the inner wall of the auxiliary block 1002 move on the outer transmission belt 6. The positioning airbag bracket 1003 is vertically fixed to the outer wall surface of the inner transmission belt 5 by bolts and then connected to the other side of the connecting slider 1001 by bolts, ensuring that the insulating rubber airbags on both sides of the positioning airbag bracket 1003 are in the correct position and normal state. The connecting slider 1001, the auxiliary block 1002, and the positioning airbag bracket 1003 form a U-shaped block structure with an opening downward and can slide smoothly on the upper end of the outer transmission belt 6. A follower auxiliary carriage 1004 is installed at the upper end of the connecting slider 1001, and the two ends of the micro ball screw 1005 are rotatably connected to the follower auxiliary carriage 1004 to ensure flexible and reliable connection. The buffer slide rail 1006 is installed at the upper end of the slide table of the micro ball screw 1005 to make it slide smoothly with the bottom end of the tooling support bracket 1007. When the tooling slider assembly 10 is impacted or needs to be finely adjusted in position, the buffer slide rail 1006 can absorb the impact energy through its own sliding or achieve fine adjustment of the tooling support bracket 1007 in the vertical direction, ensuring the stability of the items carried on the tooling support bracket 1007;

[0056] Install the tooling support bracket 1007 in place and ensure that the magnetic connection buckle 1008 is firmly fixed. When it is necessary to adjust the position of the tooling support bracket 1007, the micro ball screw 1005 can drive the movement of its slide table through the screw drive principle. The slide bar in the follower auxiliary slide frame 1004 penetrates through the slide table of the micro ball screw 1005 and is slidably connected to it, playing a role in auxiliary guiding and supporting to ensure the smooth movement of the slide table of the micro ball screw 1005. When the tooling slider assembly 10 is impacted or needs to be finely adjusted in position, the buffer slide rail 1006 can absorb the impact energy through its own sliding or achieve fine adjustment of the tooling support bracket 1007 in the vertical direction, ensuring the stability of the items carried on the tooling support bracket 1007.

[0057] Working principle: When using the anti-derailment annular guide rail with a follower type guiding structure, first, the guide rail support 1 serves as the basic supporting component to carry the entire annular guide rail system. During actual use, the connecting roller rod 2 is connected to the driving part and can rotate on the guide rail support 1. The driving gear 3 is fixed on the connecting roller rod 2. When the driving gear 3 rotates, its teeth are engaged with the inner transmission belt 5 to drive the inner transmission belt 5 to move. The inner transmission belt 5 and the outer transmission belt 6 are sleeved and connected. The movement of the inner transmission belt 5 drives the outer transmission belt 6 to move together, thus forming the circulating drive of the annular guide rail.

[0058] During the movement of the tooling slider assembly 10 along with the guide rail, the rubber roller can roll along the outer wall of the outer transmission belt 6, following the trajectory of the guide rail in real time, playing a guiding role to prevent the connecting slider 1001 from randomly deviating in the horizontal direction and ensuring its operation along the path of the annular guide rail. When the connecting slider 1001 is impacted by an external force or the operating state changes and there is a tendency to derail from the guide rail, the airbag can absorb part of the energy through deformation and at the same time give the connecting slider 1001 a certain reverse acting force to keep it on the guide rail. And the positioning airbag frame 1003 is fixed to the outer wall surface of the inner transmission belt 5 by bolts, which laterally restricts the excessive displacement of the connecting slider 1001 in the vertical direction to prevent it from derailing. Further, the connecting slider 1001, the auxiliary block 1002, and the positioning airbag frame 1003 are assembled into a U-shaped block with an opening downward. This structure enables the connecting slider 1001 to be constrained and guided from multiple directions during operation, further enhancing the anti-derailment performance.

[0059] When the position of the tooling support bracket 1007 needs to be adjusted, the micro ball screw 1005 drives its slide to move, and the slide bar in the follower auxiliary slide 1004 plays a role in auxiliary guiding and supporting to ensure the smooth movement of the slide of the micro ball screw 1005. When the tooling slider assembly 10 is impacted or needs to be finely adjusted in position, the buffer slide rail 1006 can absorb the impact energy through its own sliding or achieve fine adjustment of the tooling support bracket 1007 in the vertical direction, ensuring the stability of the items carried on the tooling support bracket 1007, overall ensuring the accuracy and stability of the transmission and guaranteeing the smooth operation of the ring rail system.

[0060] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
