Description

Technical Field

[0001] This application relates to the field of profile processing technology, and in particular to a torsion straightening system for high-precision guide rails used in high-speed elevators. Background Technology

[0002] The car of a passenger elevator achieves smooth vertical movement by sliding up and down along elevator guide rails. The elevator guide rails typically have a T-shaped cross-section and consist of a fixed plate and a guide plate vertically positioned in the center of the fixed plate. During installation, the fixed plate is secured to the building, allowing the guide plate to slide alongside the elevator car. Therefore, the straightness of the top and side working surfaces of the guide plate directly affects the smoothness and safety of the car's operation. Straightening is a crucial step in the manufacturing process of elevator guide rails.

[0003] Currently, elevator guide rail straightening is typically performed using a leveling machine. The operator first places the elevator guide rail on the leveling machine's worktable with the fixed plate horizontal and the guide plate vertical. The leveling machine then straightens the side working surfaces of the guide plate once. After the top working surface is straightened, the operator must manually flip the guide rail so that the fixed plate is vertical and the guide plate is horizontal, and the leveling machine then performs a second straightening of the top working surface of the guide plate. Because the production process is interrupted after each working surface is straightened, requiring manual flipping before resuming, the entire straightening production line cannot operate continuously, resulting in low processing efficiency for elevator guide rails.

[0004] Therefore, there is a need to provide a torsion straightening system for high-precision guide rails used in high-speed elevators. Summary of the Invention

[0005] To address the issue that existing torsion straightening systems require manual flipping of elevator rails, resulting in low processing efficiency for elevator guide rails, this application provides a torsion straightening system for high-precision guide rails used in high-speed elevators.

[0006] This application provides a torsion correction system for a high-precision guide rail for a high-speed elevator, which adopts the following technical solution: it includes a conveying component, a flipping component and two leveling machines. The two leveling machines are arranged at intervals and each forms a leveling channel in the same direction. The leveling machines can drive the workpiece inserted in the leveling channel to pass through the leveling channel and level the workpiece. The conveying assembly is capable of receiving and transporting the workpiece along the passage direction of the leveling channel; when the workpiece transported by the conveying assembly is located between the two leveling channels, the flipping assembly is capable of flipping the workpiece.

[0007] By adopting the above technical solution, the conveying component can receive and transport workpieces, allowing them to move along the leveling channel. Two leveling machines, spaced apart and equipped with leveling channels, can level the workpieces. When a workpiece is between the two leveling channels, the flipping component can flip it. Compared to existing technologies that require manual repeated flipping and handling of guide rails, resulting in high labor intensity and low work efficiency for workers, this system automates workpiece transportation, flipping, and leveling, reduces manual intervention, significantly improves production efficiency, and reduces the labor intensity of workers.

[0008] Specifically, the conveying assembly includes a base, a clamping platform, a clamping unit, two drive clamping wheels, two conveying motors, and multiple receiving rollers. The multiple receiving rollers are rotatably connected to the base at parallel intervals along the travel direction of the leveling channel. The rotation axis of each receiving roller is perpendicular to the travel direction of the leveling channel. The top roller surfaces of the multiple receiving rollers are formed as conveying surfaces for receiving the workpiece. A clamping wheel rail is provided on the clamping platform along the length direction of the receiving rollers. The axles of the two drive clamping wheels are slidably mounted on the clamping wheel rail in the vertical direction. The wheel surfaces of the two drive clamping wheels are aligned with the rail along the length direction of the leveling channel. The leveling channel forms a conveying channel in the direction of passage. The conveying motor corresponds one-to-one with the driving clamping wheel. Each conveying motor is driven by the corresponding driving clamping wheel and can drive the side of the driving clamping wheel closest to the conveying channel to rotate along the direction of passage of the leveling channel. The clamping unit is driven by the two driving clamping wheels and can drive the two driving clamping wheels to move closer or further away from each other along the clamping wheel rail to adjust the width of the conveying channel. When the workpiece is placed on the conveying surface, the workpiece is inserted into the conveying channel and abutted between the two driving clamping wheels.

[0009] By adopting the above technical solution, multiple receiving rollers can receive workpieces and form a conveying surface, facilitating workpiece placement and transportation; the clamping wheel rail allows the drive clamping wheel to slide vertically, flexibly adjusting the width of the conveying channel; the conveying motor drives the drive clamping wheel to rotate, which can move the workpiece inserted in the conveying channel along the passage direction of the leveling channel; the clamping unit can drive the two drive clamping wheels to move closer or further apart, thereby adjusting the width of the conveying channel to accommodate workpieces of different sizes, ensuring that the workpiece is stably abutted between the two drive clamping wheels for transportation, ultimately achieving efficient and stable conveying of workpieces on the conveying assembly, and improving the working efficiency of the entire torsion straightening system.

[0010] Furthermore, the clamping unit includes a bidirectional lead screw and a clamping motor. The bidirectional lead screw is rotatably connected to the clamping platform along the length direction of the receiving roller. The bidirectional lead screw has two threaded segments with opposite directions of thread. Each threaded segment is screwed with a matching nut. Each nut corresponds to a transmission motor, and each nut is connected to the corresponding transmission motor. Each nut is also connected to the clamping wheel rail, which can restrict the rotation of each nut around the bidirectional lead screw. The clamping motor is driven by the bidirectional lead screw and can drive the bidirectional lead screw to rotate.

[0011] By adopting the above technical solution, the two threaded segments with opposite directions on the double-acting screw are used in conjunction with the nuts. When the clamping motor drives the double-acting screw to rotate, the two nuts can drive the transmission motor and the drive clamping wheel to move closer or further apart along the clamping wheel rail. This allows for convenient and precise adjustment of the width of the transmission channel to accommodate workpieces of different sizes and ensures that the workpiece can be stably abutted between the two drive clamping wheels for transport.

[0012] Furthermore, the flipping assembly includes a horizontal rail, a slide table, a translation cylinder, a lifting cylinder, and a flipping block. The horizontal rail is arranged along the length direction of the receiving roller. The slide table is disposed on the horizontal rail. The translation cylinder is pulsatorically connected to the slide table and can drive the slide table to reciprocate along the horizontal rail. The cylinder body of the lifting cylinder is disposed on the translation table. The piston rod of the lifting cylinder is connected to the flipping block and can drive the flipping block to rise and fall. The top of the flipping block has an abutment surface and a receiving surface. When the flipping block rises, the abutting surface can abut against one side of the bottom of the workpiece before the receiving surface, and the side of the bottom of the workpiece away from the abutting surface will fall downward around the abutting surface and abut against the receiving surface. When the workpiece abuts against the receiving surface and the flipping block descends, the workpiece can fall onto the conveying surface and separate from the flipping block.

[0013] By adopting the above technical solution, the horizontal rail, slide table, and translation cylinder can be used to realize the reciprocating movement of the flipping block along the length of the receiving roller, which facilitates the adjustment of the flipping block's position to meet the flipping requirements of the workpiece. The lifting cylinder drives the flipping block to rise and fall, so that when the flipping block rises, the contact surface can first contact one side of the bottom of the workpiece, forcing the other side of the bottom of the workpiece to fall downwards around the contact surface until it contacts the receiving surface, thus realizing the automatic flipping of the workpiece. After the flipping is completed, the flipping block descends, and the workpiece can fall onto the conveyor surface and separate from it, thereby realizing the automatic flipping function of the workpiece during the conveying process, avoiding manual flipping, improving work efficiency, reducing manual labor intensity, and ensuring the continuous automated operation of the entire straightening system.

[0014] Furthermore, the top of the flipping block is provided with a first wedge block and a horizontal block. The wedge tip of the first wedge block extends upward and forms the abutment surface at its end. A first positioning groove is formed between the horizontal block and the first wedge block, and the top of the horizontal block forms the receiving surface. The workpiece includes a fixed plate and a guide plate arranged along the same length direction. One side of the guide plate along its own length direction is connected to the middle of one side of the fixed plate. When the flipping block rises, the wedge tip of the first wedge block can abut against the side of the fixed plate away from the guide plate along the length direction of the fixed plate, and the other side of the fixed plate away from the guide plate along the length direction of the fixed plate slides into the first positioning groove along the body of the first wedge block. The side edge of the guide plate away from the fixed plate abuts against the receiving surface, so that when the flipping block descends, both the side edge of the fixed plate away from the first wedge block and the side edge of the guide plate away from the fixed plate can abut against the conveying surface.

[0015] By adopting the above technical solution, when the flipping block rises, the wedge tip of the first wedge block abuts against the fixed plate, allowing the other side of the fixed plate to slide into the first positioning groove. At the same time, the edge of the guide plate abuts against the receiving surface, realizing the flipping action of the workpiece. When the flipping block falls, the corresponding edges of the fixed plate and the guide plate abut against the conveying surface, allowing the workpiece to fall smoothly onto the conveying surface, completing the flipping process. This avoids manual flipping and improves the automation level and efficiency of guide rail processing.

[0016] Furthermore, the top of the flipping block is provided with a second wedge block and a third wedge block, a second positioning groove is formed between the blocks of the second wedge block and the third wedge block, the wedge tip of the second wedge block is higher than the wedge tip of the third wedge block and forms the abutment surface, the side of the third wedge block near the second positioning groove forms the receiving surface, the workpiece includes a fixed plate and a guide plate arranged along the same length direction, and one side edge of the guide plate along its own length direction is connected to the middle of one side plate surface of the fixed plate; When the flipping block rises, the wedge tip of the second wedge block can abut against the side of the guide plate away from the fixed plate, causing the fixed plate to drive the guide plate to flip down around the wedge tip of the second wedge block until the bottom edge of the fixed plate is in contact with the wedge body of the second wedge block, and slides into the second positioning groove along the wedge body of the second wedge block. The side of the fixed plate away from the guide plate abuts against the third wedge block, so that when the flipping block descends, the side of the fixed plate away from the guide plate abuts against the conveying surface.

[0017] By adopting the above technical solution, using the second and third wedge blocks at the top of the flipping block, when the flipping block rises, the wedge tip of the second wedge block abuts against the side of the guide plate away from the fixed plate, which enables the fixed plate to drive the guide plate to flip down around the wedge tip. The wedge body of the bottom edge of the fixed plate slides into the second positioning groove, and the plate surface of the fixed plate away from the guide plate abuts against the third wedge block, realizing the automatic flipping of the workpiece. When the flipping block descends, the plate surface of the fixed plate away from the guide plate can accurately fall onto the conveying surface, avoiding manual flipping, improving the flipping efficiency and accuracy in the workpiece distortion straightening process, and thus improving the working efficiency of the entire straightening system.

[0018] Furthermore, the flipping assembly includes a flipping arm, an expansion bladder, an air pump, and a tripping unit. The flipping arm includes a rotating rod, a drive rod, a driven rod, a suction cup, a flipping motor, and a bent tube. The bottom end of the rotating rod is hinged to the base, and the rotation axis of the rotating rod is perpendicular to the length direction of the receiving roller. The flipping motor is driven by the rotating rod and can drive the rotating rod to rotate around the hinge axis at the bottom end of the rotating rod. One end of the drive rod is hinged to the top end of the rotating rod, and the other end of the drive rod is hinged to one end of the driven rod. The suction cup is located on the other end of the driven rod. The expansion bladder is disposed between the shaft of the drive rod and the shaft of the rotating rod. An air hole is provided on the shaft of the rotating rod. One end of the air hole is connected to the air inlet of the air pump through a pipe, and the other end of the air hole is connected to the expansion bladder. A drive hole is provided on the shaft of the drive rod. One end of the drive hole is connected to one end of the bent tube, and the other end of the drive hole is connected to the expansion bladder. A driven hole is provided on the driven rod. One end of the driven hole is connected to the end of the bent tube away from the drive rod, and the other end of the driven hole is connected to the air outlet of the suction cup. The tripping unit includes a tripping block and a telescopic cylinder. Two conveying components are provided between the two leveling channels. The outlet of one of the two leveling channels leads to the conveying surface of one of the two conveying components, forming a first surface. The conveying surface of the other of the two conveying components leads to the entrance of the other of the two leveling channels, forming a second surface. A tripping interval is formed between the two conveying components. The tripping block is located within the tripping interval. The telescopic cylinder is kinetically connected to the tripping block and can drive the tripping block to rise and fall. The top of the tripping block has a flat surface, and a tripping protrusion is provided on the flat surface. The workpiece includes a fixed plate and a guide plate arranged along the same length direction. One side of the guide plate along its own length direction is connected to the middle of one side of the fixed plate. When the workpiece is placed on the first surface, the side of the fixed plate away from the guide plate is in contact with the first surface. When the air pump delivers air into the air hole, the expansion bladder expands and restricts the drive rod from moving the driven rod closer to the shaft of the rotating rod. The flipping motor can drive the rotating rod to move the suction cup closer to the first surface until the suction cup abuts against the side edge of the guide plate of the workpiece placed on the first surface away from the fixed plate, so that when the air pump draws air from the air hole, the suction cup adsorbs the workpiece placed on the first surface, and the expansion bladder contracts and no longer restricts the drive rod from moving the driven rod closer to the shaft of the rotating rod. When the rotating motor drives the rotating rod to move the suction cup closer to the second surface, the telescopic cylinder drives the trip block to rise until the flat surface is flush with the first surface and the second surface. The fixing plate can first slide along the first surface to the flat surface, and then abut against the trip protrusion via the edge of the fixing plate. At this time, the rotating rod can apply a force close to the second surface to the guide plate via the driving rod, the driven rod and the suction cup, so that the fixing plate flips around the trip protrusion to the second surface and slides past the trip protrusion along the flat surface to the second surface. The side edge of the guide plate away from the fixing plate and the side edge of the fixing plate abut against the second surface.

[0019] By adopting the above technical solution, the workpiece guide plate is adsorbed by the suction cup in the flipping arm, and the range of motion of the driven rod is controlled by the expansion bladder. The workpiece is moved by the rotation of the rotating rod driven by the flipping motor. At the same time, the tripping block of the tripping unit rises, so that the fixed plate abuts against the tripping protrusion, which enables the workpiece to be flipped smoothly from the first side and slid to the second side. This realizes the automatic flipping of the workpiece between the conveying components, avoids manual flipping, effectively improves the processing efficiency of the high-precision guide rail torsion correction system for high-speed elevators, reduces manual intervention, and reduces the labor intensity of workers.

[0020] Furthermore, the tilting arm also includes a one-way valve, which is located in the drive hole and can restrict gas from passing through the drive hole into the bend.

[0021] By adopting the above technical solution, a one-way valve can be installed in the drive hole to restrict gas from passing through the drive hole into the bend, so as to prevent gas from being ejected from the suction cup when the air pump inputs gas into the air hole. This ensures that the sealing performance of the suction cup will not be reduced due to gas ejection from the suction cup when it comes into contact with the guide plate, thus facilitating the suction cup to adsorb the guide plate.

[0022] Furthermore, the suction cup body includes a base portion and a pair of extension portions. The two extension portions are disposed opposite to each other on the base portion and form an insertion channel between the two extension portions that is adapted to the guide plate. The side edge of the guide plate away from the fixed plate can be inserted into the insertion channel and abut against the base portion, and each extension portion abuts against the adjacent guide plate surface.

[0023] By adopting the above technical solution, the insertion channel formed by the base part of the suction cup body and a pair of extension parts is adapted to the guide plate, so that the side of the guide plate away from the fixed plate can be inserted into the insertion channel and abut against the base part, and the extension part abuts against the surface of the adjacent guide plate, which can increase the contact area between the suction cup and the guide plate, improve the stability of adsorption, and thus more reliably adsorb the workpiece for flipping operation.

[0024] Specifically, it also includes a loading conveyor belt and a unloading conveyor belt. The two leveling machines are located on the loading conveyor belt and the unloading conveyor belt. The loading conveyor belt can transport the workpiece to the entrance of one of the two leveling channels, and the unloading conveyor belt can transport the workpiece out of the exit of the other of the two leveling channels.

[0025] By adopting the above technical solution, the feeding conveyor belt can automatically transport workpieces to the entrance of the leveling channel, and the unloading conveyor belt can promptly remove workpieces output from the exit of the leveling channel. This realizes automatic feeding and unloading of workpieces, reduces manual intervention, improves the overall working efficiency of the high-precision guide rail torsion straightening system for high-speed elevators, and makes the entire straightening process more continuous and automated.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The conveying component, the flipping component, and two leveling machines work together to achieve automated assembly line operation, completing the conveying, flipping, and positioning of the guide rail, as well as the continuous straightening of the top and side working surfaces in one go. This solves the problem of production process interruption and inability to operate continuously in the existing technology, and improves processing efficiency. 2. No manual intervention is required for the flipping and handling of the guide rails, reducing the labor intensity for workers; 3. The entire process is continuous and automated, significantly reducing interruptions in intermediate steps and improving the processing efficiency of elevator guide rails.

[0029] The following is in conjunction with the appendix Figure 1-7 Further explanation: See Figure 1 and Figure 3In the first embodiment, a torsion straightening system for a high-precision guide rail for a high-speed elevator is used to level a workpiece 4, such as a high-precision guide rail for a high-speed elevator. The workpiece 4 includes a fixed plate 41 and a guide plate 42 arranged along the same length direction. One side of the guide plate 42 along its own length direction is connected to the middle of one side of the fixed plate 41, so that the cross-section of the workpiece 4 is formed into a "T" shape. The torsion straightening system for the high-precision guide rail for a high-speed elevator includes a feeding conveyor belt 5, a discharging conveyor belt 6, four conveying components 1, four flipping components 2, and two leveling machines 3. The two leveling machines 3 are spaced apart and each has a leveling channel in the same direction. Each leveling machine 3 can drive the workpiece 4 inserted in the leveling channel to pass through the leveling channel and level the fixed plate 41 and guide plate 42 of the workpiece 4. The leveling machine 3 is prior art and will not be described in detail here.Each leveling channel has a conveying assembly 1 at its entrance and exit. Each conveying assembly 1 includes a base 11, a clamping platform 12, a clamping unit 13, two drive clamping wheels 14, two conveying motors 15, and multiple receiving rollers 16. The multiple receiving rollers 16 are rotatably connected to the base 11 at parallel intervals along the travel direction of the leveling channel. The rotation axis of each receiving roller 16 is perpendicular to the travel direction of the leveling channel. The top roller surface of the multiple receiving rollers 16 is formed as a conveying surface for receiving workpieces 4. The top of the clamping platform 12 has clamping wheel grooves along the length direction of the receiving rollers 16. The inside of the clamping platform 12 has a receiving cavity, and the clamping unit 13 is located in the receiving cavity and includes bidirectional clamping units. The lead screw 131 and clamping motor 132 are arranged along the length of the receiving roller 16. Both ends of the lead screw 131 are rotatably connected to the bottom wall of the receiving cavity through bearing seats. A track groove 121 is formed on the bottom wall of the receiving cavity along the length of the lead screw 131, which forms a wheel clamping rail. Two threaded sections with opposite thread directions are formed on the body of the lead screw 131. Each threaded section is screwed with a matching nut 133. The nut 133 can be a nut with a square cross-section. Each nut 133 corresponds one-to-one with a transmission motor 15. Each nut 133 is connected to the corresponding transmission motor 15. The bottom ends of the nuts 133 are inserted into the track grooves 121 and can slide along the track grooves 121. The groove walls of the track grooves 121 can abut against the nuts 133 and restrict the nuts 133 from rotating with the bidirectional lead screw 131. The transmission motors 15 and drive clamping wheels 14 correspond one-to-one. The axles of the two drive clamping wheels 14 pass through the clamping wheel grooves in the vertical direction and are connected to the output shafts of the corresponding transmission motors 15. A transmission channel is formed between the wheel surfaces of the two drive clamping wheels 14 along the passage direction of the leveling channel. Each transmission motor 15 can drive the side of the corresponding drive clamping wheel 14 closest to the transmission channel to rotate along the passage direction of the leveling channel. The clamping motor 132 and the double The bidirectional lead screw 131 is connected to and driven to rotate. This allows the two oppositely oriented thread segments on the bidirectional lead screw 131 to engage with the nut 133. When the clamping motor 132 drives the bidirectional lead screw 131 to rotate, the two nuts 133 drive the transmission motor 15 and the drive clamping wheel 14 to move closer or further apart along the clamping wheel rail. This facilitates convenient and precise adjustment of the transmission channel width to accommodate workpieces 4 of different sizes. It ensures that the workpiece 4 is stably abutted between the two drive clamping wheels 14 for transport, ultimately achieving efficient and stable transport of the workpiece 4 on the transmission assembly 1 and improving the overall efficiency of the torsion straightening system.

[0030] See Figure 1 and Figure 4A conveying assembly 1 is provided at the entrance of one of the two leveling channels, and the conveying surface of the conveying assembly 1 is formed as the starting surface. Two conveying assemblies 1 are provided between the two leveling channels. The outlet of one of the two leveling channels leads to the conveying surface of the two conveying assemblies 1, forming the first surface. The conveying surface of the other conveying assembly 1 leads to the entrance of the other of the two leveling channels, forming the second surface. A last conveying assembly 1 is provided at the outlet of the other of the two leveling channels, and the conveying surface of the conveying assembly 1 is formed as the ending surface. The loading conveyor belt 5 is located on one side of the starting surface and can transport the workpiece 4 onto the starting surface. At this time, the workpiece 4's fixing plate 41 is away from the guide plate 42. One side of the plate is in contact with the body of the feeding conveyor belt 5 and the starting surface; two of the four flipping components 2 are located between the first surface and the second surface and can flip and move the workpiece 4 on the first surface to the second surface. When the workpiece 4 is on the second surface, the side of the fixed plate 41 away from the first wedge block 251 and the side of the guide plate 42 away from the fixed plate 41 are both in contact with the second surface; the remaining two of the four flipping components 2 are located between the end surface and the unloading conveyor belt 6 and can flip and move the workpiece 4 on the end surface to the body of the unloading conveyor belt 6. When the workpiece 4 is on the body of the unloading conveyor belt 6, the side of the fixed plate 41 of the workpiece 4 away from the guide plate 42 is in contact with the body of the unloading conveyor belt 6.

[0031] See Figure 3 and Figure 4Each flipping assembly 2 includes a horizontal rail 21, a slide table 22, a translation cylinder 23, a lifting cylinder 24, and a flipping block 25. The horizontal rail 21 is arranged along the length direction of the receiving roller 16. The slide table 22 is disposed on the horizontal rail 21. The translation cylinder 23 is connected to the slide table 22 and can drive the slide table 22 to reciprocate along the horizontal rail 21. The cylinder body of the lifting cylinder 24 is disposed on the translation table. The piston rod of the lifting cylinder 24 is connected to the flipping block 25 and can drive the flipping block 25 to rise and fall. The top of the flipping block 25 has an abutment surface and a receiving surface. The top of each flipping block 25 located between the first surface and the second surface is provided with a first wedge block 251 and a horizontal block 252. The wedge tip of the first wedge block 251 extends upward and forms an abutment surface at its end. A first positioning groove 253 is formed between the horizontal block 252 and the first wedge block 251, and the top of the horizontal block 252 is formed as... The receiving surface of the workpiece 4 includes a fixed plate 41 and a guide plate 42 arranged along the same length direction. One side of the guide plate 42 along its own length direction is connected to the middle of one side of the fixed plate 41. When the flipping block 25 rises, the wedge tip of the first wedge block 251 can abut against the side of the fixed plate 41 away from the guide plate 42 along the length direction of the fixed plate 41, and the other side of the fixed plate 41 away from the guide plate 42 along the length direction of the fixed plate 41 slides into the first positioning groove 253 along the block body of the first wedge block 251. The side of the guide plate 42 away from the fixed plate 41 abuts against the receiving surface, so that when the flipping block 25 falls, the side of the fixed plate 41 away from the first wedge block 251 and the side of the guide plate 42 away from the fixed plate 41 can abut against the second surface, thereby realizing the automatic flipping of the workpiece 4. After the flipping is completed, the flipping block 25 descends, and the workpiece 4 can fall onto the second surface and separate from it. Finally, the workpiece 4 is clamped by the two corresponding drive clamping wheels 14 on the second surface, and the workpiece 4 can be transported to the corresponding leveling machine 3.

[0032] See Figure 3 and Figure 4The top of the turning block 25 located between the end point and the unloading conveyor belt 6 is provided with a second wedge block 254 and a third wedge block 255. A second positioning groove 256 is formed between the blocks of the second wedge block 254 and the third wedge block 255. The wedge tip of the second wedge block 254 is higher than the wedge tip of the third wedge block 255 and forms an abutment surface. The side of the third wedge block 255 near the second positioning groove 256 forms a receiving surface. The workpiece 4 includes a fixed plate 41 and a guide plate 42 arranged along the same length direction. One side of the guide plate 42 along its own length direction is connected to the middle of one side of the fixed plate 41. When the flipping block 25 rises, the wedge tip of the second wedge block 254 can abut against the side of the guide plate 42 away from the fixed plate 41, and the fixed plate 41 drives the guide plate 42 to flip down around the wedge tip of the second wedge block 254 until the bottom edge of the fixed plate 41 fits against the wedge body of the second wedge block 254, and slides into the second positioning groove 256 along the wedge body of the second wedge block 254. The side of the fixed plate 41 away from the guide plate 42 abuts against the third wedge block 255, so that when the flipping block 25 falls, the side of the fixed plate 41 away from the guide plate 42 abuts against the belt body of the unloading conveyor belt 6.

[0033] Specifically, limiting rollers 7 and abutment joints 8 and pushing cylinders 9 can be respectively set on both sides of the receiving roller 16 on the second surface. The rotating shaft of the limiting roller 7 is connected to the base 11 in a vertical direction. The cylinder body of the pushing cylinder 9 is set on the base 11. The piston rod of the pushing cylinder 9 is connected to the abutment joint 8 and can drive the abutment joint 8 to move closer to or away from the limiting roller 7. The distance between the end of the abutment joint 8 close to the limiting roller 7 and the second surface is less than half the width of the fixed plate 41. When the flipping block 25 places the workpiece 4 on the second surface, the workpiece 4 will fall between the limiting roller 7 and the abutment joint 8 and between the two corresponding driving clamping rollers 14 on the second surface. At this time, the user can first drive the abutment 8 close to the limiting roller 7 so that the abutment 8 first abuts against the lower half of the fixed plate 41, and then force the workpiece 4 to be clamped between the abutment 8 and the limiting roller 7 after flipping a certain angle. At this time, only the edge of the fixed plate 41 abuts against the second surface of the workpiece 4, and the surface of the guide plate 42 is parallel to the second surface. Then the user can control the two drive clamping wheels 14 to abut against the side edge of the guide plate 42 away from the fixed plate 41 and the side surface of the fixed plate 41 away from the guide plate 42 respectively, and transport the workpiece 4, thereby controlling the posture of the workpiece 4 when entering the second leveling channel.

[0034] See Figure 5 , Figure 6 and Figure 7The flipping assembly 2 between the first and second sides may include a flipping arm 26, an expansion bladder 27, an air pump 28, and a tripping unit 29. The flipping arm 26 includes a rotating rod 261, a drive rod 262, a driven rod 263, a suction cup 264, a flipping motor 265, a bend 266, and a one-way valve 2622. The bottom end of the rotating rod 261 is hinged to the base 11, and the rotation axis of the rotating rod 261 is perpendicular to the length direction of the receiving roller 16. The flipping motor 265 is driven by the rotating rod 261 and can drive the rotating rod 261 to rotate around the hinge axis at the bottom end of the rotating rod 261. One end of the drive rod 262 is hinged to the top of the rotating rod 261, and the other end of the drive rod 262 is hinged to one end of the driven rod 263. A suction cup 264 is located on the other end of the driven rod 263. An expansion bladder 27 is located between the shafts of the drive rod 262 and the rotating rod 261. An air hole 2611 is provided on the shaft of the rotating rod 261. One end of the air hole 2611 is connected to the air inlet of the air pump 28 via a pipe, and the other end of the air hole 2611 is connected to the expansion bladder 27. A drive hole 2621 is provided on the shaft of the drive rod 262. One end of 21 is connected to one end of the bend 266, and the other end of the drive hole 2621 is connected to the expansion bladder 27. A driven hole 2631 is provided on the driven rod 263. One end of the driven hole 2631 is connected to the end of the bend 266 away from the drive rod 262, and the other end of the driven hole 2631 is connected to the air outlet of the suction cup 264. A one-way valve 2622 is provided in the drive hole 2621 and can restrict gas from passing through the drive hole 2621 into the bend 266. The tripping unit 29 includes a tripping block 291 and a telescopic cylinder 292. A tripping block 291 is provided between the two leveling channels. There are two conveying components 1. The outlet of one of the two leveling channels leads to the conveying surface of one of the two conveying components 1 and forms the first surface. The conveying surface of the other of the two conveying components 1 leads to the inlet of the other of the two leveling channels and forms the second surface. A tripping gap is formed between the two conveying components 1. A tripping block 291 is provided in the tripping gap. A telescopic cylinder 292 is connected to the tripping block 291 and can drive the tripping block 291 to rise and fall. The top of the tripping block 291 has a flat surface, and a tripping protrusion 2911 is provided on the flat surface.

[0035] The implementation principle of the flipping component 2 in the second embodiment of this application is as follows: When the air pump 28 supplies air into the air hole 2611, the expansion bladder 27 expands and restricts the drive rod 262 from driving the driven rod 263 to approach the shaft of the rotating rod 261. At this time, the user can control the flip motor 265 to rotate the rotating rod 261 until the shaft of the rotating rod 261 is perpendicular to the horizontal plane. The shaft of the drive rod 262 will approach the first surface along the length of the receiving roller 16, and the driven rod 263 will drop vertically, so that the suction cup 264 just abuts against the guide plate 42 of the workpiece 4 placed on the first surface. On the side of the fixed plate 41; then the user can control the air pump 28 to draw air from the air hole 2611, at which time the suction cup 264 will adsorb the workpiece 4 placed on the first surface, and the expansion bladder 27 will contract and no longer restrict the drive rod 262 to drive the driven rod 263 to approach the rod body of the rotating rod 261; then the user can control the flip motor 265 to drive the rotating rod 261 to drive the suction cup 264 to approach the second surface, and at the same time control the telescopic cylinder 292 to drive the trip block 291 to rise so that the flat surface is flush with the first surface and the second surface; At this time, the fixed plate 41 can first slide along the first surface to the flat surface, and then abut against the tripping protrusion 2911 via the edge of the fixed plate 41. Since the rotating rod 261 can apply a force close to the second surface to the guide plate 42 via the driving rod 262, the driven rod 263 and the suction cup 264, the fixed plate 41 can be flipped around the tripping protrusion 2911 to the second surface and slide along the flat surface to the second surface. The edge of the guide plate 42 away from the fixed plate 41 and the edge of the fixed plate 41 are both abutted against the second surface, so that the suction cup 264 in the flipping arm 26 can be used to adsorb the guide plate 42 of the workpiece 4. The range of motion of the driven rod 263 is controlled by the expansion bladder 27. The rotating rod 261 is driven to rotate by the flipping motor 265 to move the workpiece 4. At the same time, the tripping block 291 of the tripping unit 29 The lifting mechanism allows the fixed plate 41 to contact the tripping protrusion 2911, enabling the workpiece 4 to smoothly flip and slide from the first side to the second side. This achieves automatic flipping of the workpiece 4 between the conveying components 1, avoiding manual flipping and effectively improving the processing efficiency of the high-precision guide rail twisting correction system for high-speed elevators. It also reduces manual intervention and lowers the labor intensity of workers. Furthermore, the one-way valve 2622 installed in the drive hole 2621 restricts gas from passing through the drive hole 2621 into the bend 266, preventing gas from being ejected from the suction cup 264 when the air pump 28 inputs gas into the air hole 2611. This ensures that the sealing performance of the suction cup 264 is not reduced due to gas ejection when it contacts the guide plate 42, thus facilitating the suction cup 264's adsorption of the guide plate 42.

[0036] Specifically, the suction cup 264 can be configured to include a base portion 2641 and a pair of extension portions 2642. The two extension portions 2642 are disposed opposite to each other on the base portion 2641, forming an insertion channel between the two extension portions 2642 that is adapted to the guide plate 42. The side edge of the guide plate 42 away from the fixed plate 41 can be inserted into the insertion channel and abut against the base portion 2641. Each extension portion 2642 abuts against the surface of the adjacent guide plate 42, thereby increasing the contact area between the suction cup 264 and the guide plate 42, improving the stability of the adsorption, and thus more reliably adsorbing the workpiece 4 for flipping operation; it can also be configured to be mounted on the drive rod 262. A limiting protrusion 2623 is provided at one end near the rotating rod 261. This limiting protrusion 2623 can abut against the rotating rod 261 when the angle between the driving rod 262 and the rotating rod 261 reaches 90°, thus limiting the angle between the driving rod 262 and the rotating rod 261 from expanding further. The bend 266 can be a bellows so that the two ends of the bend 266 can adaptively extend and retract when the driven rod 263 rotates around the driving rod 262. A torsion spring can also be provided on the hinge between the driving rod 262 and the driven rod 263. This torsion spring can limit the angle between the driven rod 263 and the driving rod 262 from being greater than 90°.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
