Description

Technical Field

[0001] This invention relates to the field of half-shaft assembly technology, specifically to a half-shaft assembly device and assembly method for new energy forklifts. Background Technology

[0002] Forklifts are self-propelled loading and unloading conveying machines equipped with forks and lifting devices. They are various wheeled handling vehicles used for loading, unloading, stacking, and short-distance transportation of palletized goods. The half-shaft of a forklift is the shaft that transmits torque between the gearbox reducer and the drive wheel. It is an essential main power component in a forklift. Therefore, the assembly of the half-shaft is particularly important during forklift production.

[0003] Currently in forklift production, the half-shafts still need to be installed manually by assembly technicians. When assembling the half-shaft and bearing, a rubber hammer is needed to tap the end of the half-shaft before it can be inserted into the inner hole of the bearing. This assembly process is cumbersome, has low efficiency, and the precision of manual assembly is not high enough. Summary of the Invention

[0011] As a preferred embodiment of the present invention, a path groove is provided on one side of each of the two transport frames that are close to each other, and two sliding pins distributed on the left and right are fixedly installed on the front and back of the transport tray, and the outer wall of the sliding pin is slidably connected to the inner wall of the path groove.

[0012] As a preferred embodiment of the present invention, a return spring is sleeved around the clamping top rod, and the return spring is fixedly installed between the telescopic seat and the V-shaped clamping plate.

[0013] In a preferred embodiment of the present invention, the transport pallet is located at the bottom of the boss.

[0014] As a preferred embodiment of the present invention, the side of the chuck away from the servo cylinder is provided with a V-shaped clamping groove.

[0015] As a preferred embodiment of the present invention, two hydraulic cylinders distributed front and rear are fixedly installed on the top of each longitudinal beam, and the bottom of the output rod of the hydraulic cylinder is fixedly connected to the top of the guide rail.

[0016] A new energy forklift half-shaft assembly device includes the following usage steps:

[0017] S1. Drive the half-shaft carrier component and the bearing carrier component to operate through the drive component;

[0018] S2. First, a worker places the half shaft to be assembled vertically inside one of the clamping seats on the left end. The output rods of the two servo cylinders push the two clamps towards the middle to clamp and fix the half shaft.

[0019] S3. At the same time, another worker places the bearing that matches the half shaft on top of the carrier plate at the left end of the bearing carrier component.

[0020] S4. During the operation of the half-shaft transport component, multiple surrounding plates rotate around the periphery of the guide rail, transporting the clamped half-shaft to the right. During this period, the bearing transport component operates simultaneously, causing multiple transport pallets to move between the two transport frames, transporting the bearing to the right.

[0021] S5. When the enclosure moves the clamped half shaft to the bottom of the boss, the boss pushes the clamping seat down along the two guide rods through the convex force of the boss on the downward pressing rod. This causes the half shaft, which is clamped by the two chucks to move down together, so that the bottom of the half shaft is inserted into the bearing inner hole located directly below it, thereby automatically completing the assembly of the half shaft and the bearing.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. In this invention, the half-shaft is clamped and estimated by the half-shaft transport component, and the half-shaft transport component and the bearing transport component are driven to operate together by the drive component. When the surrounding plate in the half-shaft transport component carries the clamped half-shaft to the bottom of the boss, the convex surface thrust of the boss on the downward pressing rod pushes the clamping seat downward along the two guide rods, thereby driving the half-shaft held to the right by the two chucks to move downward together, so that the bottom of the half-shaft is just inserted into the bearing inner hole located directly below it, thereby automatically completing the assembly of the half-shaft and the bearing. Compared with manual assembly, the assembly efficiency and assembly accuracy are improved.

[0024] 2. In this invention, by rotating the positive and negative lead screws, the two adjusting plates move away from or towards each other under the action of the positive and negative threads and the threads of the two adjusting plates. This causes the two guide plates to move together, adjusting the distance between the two guide plates, thereby controlling the movement distance of the two clamping top rods towards the center. This further adjusts the front and rear clamping distance of the two V-shaped clamping plates, making it easier to clamp bearings of different diameters. At the same time, the sliding connection between the adjusting plates and the guide rods ensures the stability of the adjusting plates and guide plates during adjustment. Furthermore, the hydraulic cylinder output rod drives the guide rail to move up and down, further driving the track groove and the surrounding plate to move up and down. This allows the device to be adapted for the assembly of half-shafts of different lengths, improving the versatility of the device. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figure 1-10 The technical solution provided by the present invention specifically includes the following embodiments:

[0038] Example 1: A new energy forklift half-shaft assembly device includes a base 1, square tubes 2 are fixedly installed at the four corners of the top of the base 1, two longitudinal beams 3 are fixedly installed on the top of the base 1 and distributed on the left and right, the longitudinal beams 3 are fixedly installed on the top of the square tubes 2, half-shaft carrying components 4 are provided at the bottom of the two longitudinal beams 3, and bearing carrying components 5 are provided on the top of the base 1.

[0039] The half-shaft transport component 4 includes a guide rail 401. A track groove 403 is formed on the outer wall of the guide rail 401. Multiple equally spaced sliders 404 are slidably mounted inside the track groove 403. A surrounding plate 405 is fixedly mounted on one end of each slider 404. Two vertically distributed fixing ears 406 are fixedly mounted on the left and right sides of the surrounding plate 405 away from the sliders 404. A guide rod 407 is connected between the two fixing ears 406. A clamping seat 408 is slidably mounted on the outer wall of the two guide rods 407. A lifting spring 409 is sleeved around the guide rod 407 and fixedly mounted on the bottom of the clamping seat 408, with the bottom of the lifting spring 409 abutting against the top of the lower fixing ear 406. Telescopic grooves 4010 are formed on the left and right walls of the clamping seat 408, and chucks 4 are slidably mounted inside each telescopic groove 4010. 011, servo cylinders 4012 are fixedly installed on the left and right sides of the clamping seat 408. The output rod of the servo cylinder 4012 moves through the clamping seat 408 and is fixedly connected to the surface of the chuck 4011. Torque seats 4013 are fixedly installed on the left and right sides of the surrounding plate 405. A hinge rod 4014 is hinged between two adjacent torque seats 4013. A fixed pressure seat 4015 is fixedly installed on the top of the clamping seat 408. A downward pressure rod 4016 is fixedly installed at the top of the fixed pressure seat 4015 away from the surrounding plate 405. Arc-shaped fixing pieces 4019 are fixedly installed on the top left and top right ends of the guide rail 401. A guide ring 4017 is fixedly installed on the periphery of the four arc-shaped fixing pieces 4019. The guide ring 4017 is located on the top of multiple downward pressure rods 4016. A boss 4018 is fixedly installed at the bottom front end of the guide ring 4017.

[0040] The drive component includes two left and right distributed bearing seats 4020 fixedly installed at the top rear end of the guide rail 401. A threaded rod 4021 is rotatably installed between the two bearing seats 4020. A motor fixing plate 4022 is fixedly installed inside the guide rail 401. A servo motor 4023 is fixedly installed on the left side of the motor fixing plate 4022. An active synchronous pulley 4024 is fixedly installed on the output shaft of the servo motor 4023. A driven synchronous pulley 4025 is fixedly installed at one end of the threaded rod 4021. A synchronous belt 4026 is sleeved between the active synchronous pulley 4024 and the driven synchronous pulley 4025. Pull pins 4027 are fixedly installed on the upper side of the side of the enclosure plate 405 near the hydraulic cylinder 402. The pull pins 4027 mesh with the threaded rod 4021.

[0041] Specifically, in this embodiment, the output shaft of the servo motor 4023 drives the active synchronous pulley 4024 to rotate, and under the transmission action of the synchronous belt 4026, it drives the driven synchronous pulley 4025 and the threaded rod 4021 to rotate. The rotation of the threaded rod 4021 generates a helical thrust, which pushes a pin 4027 meshing with it to move. The movement of the pin 4027 causes the surrounding plate 405 and the slider 404 to move together. Since the surrounding plates 405 are all hinged by the torsion seat 4013 and the hinge rod 4014, the helical force of the threaded rod 4021 is... The thrust acts on any one of the pull pins 4027, causing multiple side plates 405 to rotate around the periphery of the guide rail 401. Since the side plates 405 are all slidably connected to the track groove 403 via sliders 404, the rotation of the side plates 405 along the periphery of the guide rail 401 is more stable. At the same time, the worker installs the half shafts one by one from the left end of the half shaft carrier 4 into the inside of the operating clamping seat 408, that is, places the half shafts between the two chucks 4011, and the output rods of the two servo cylinders 4012 push the two chucks together. 4011 is pushed towards the center to clamp and fix the half-shaft. The top of the half-shaft, clamped between the two clamps 4011, must abut against the bottom of the fixing base 4015. The clamped half-shaft moves along with the surrounding plate 405, transporting it to the right end of the device. During this process, the top of the downward pressing rod 4016 slides along the bottom of the guide ring 4017. When the downward pressing rod 4016 slides to the bottom of the boss 4018, the top of the downward pressing rod 4016 is pushed downward by the boss 4018. 016 moves downwards, driving the clamping seat 408 to slide downwards along the outer wall of the guide rod 407 via the fixed pressure seat 4015. The downward movement of the clamping seat 408 drives the servo cylinder 4012, the chuck 4011, and the clamped half shaft to move downwards together, thereby providing a downward thrust to the half shaft. At the same time, the bearing carrier component 5 carries the bearing and operates together with the half shaft carrier component 4. The bottom of the downward-pushed half shaft is just inserted into the inner hole of the bearing carried by the bearing carrier component 5, thereby automatically completing the assembly of the half shaft and the bearing, thus improving the assembly efficiency of the half shaft.

[0042] Furthermore, V-shaped clamping grooves 40111 are provided on the side of the chuck 4011 away from the servo cylinder 4012. When the output rods of the two servo cylinders 4012 push the chuck 4011 to move towards the center, the movement of the two chucks 4011 towards the center will cause the two V-shaped clamping grooves 40111 to move together. The two V-shaped clamping grooves 40111 just clamp and limit the outer wall of the half shaft, improving the stability of the half shaft being clamped.

[0043] Furthermore, two hydraulic cylinders 402, distributed front and rear, are fixedly installed on the top of the longitudinal beam 3. The bottom of the output rod of the hydraulic cylinder 402 is fixedly connected to the top of the guide rail 401. The output rod of the hydraulic cylinder 402 drives the guide rail 401 to move up and down, which in turn drives the track groove 403 and the surrounding plate 405 to move up and down. This makes the device applicable to the assembly of half shafts of different lengths, thus improving the versatility of the device.

[0044] Example 2: The bearing carrier component 5 includes two carrier frames 501 fixedly installed on the top of the base 1. The two carrier frames 501 are arranged front to back. A plurality of carrier trays 503 are arranged equidistantly between the two carrier frames 501. The carrier trays 503 are located at the bottom of the boss 4018. Two carrier rollers 509 are rotatably installed between the two carrier frames 501. A pulley 5010 is fixedly installed in the middle of the outer wall of each of the two carrier rollers 509. A carrier belt 5011 is sleeved between the two pulleys 5010. The outer wall of the carrier belt 5011 is flush with the carrier tray 503. The outer side is fixedly connected, and two telescopic seats 505 distributed front and rear are fixedly installed on the side of the transport pallet 503 away from the transport belt 5011. Clamping rods 506 are slidably installed inside the two telescopic seats 505. V-shaped clamping plates 507 are fixedly installed at the ends of the two clamping rods 506 that are close to each other. Guide plates 5014 are movably provided on the top of the two transport frames 501. Inclined surfaces 5015 are opened on the left side of the side of the two guide plates 5014 that are close to each other. The height of the guide plates 5014 corresponds to the height of the clamping rods 506. The bearing transport component 5 also includes a drive component.

[0045] A linkage shaft 4028 is fixedly mounted on the output shaft end of the servo motor 4023. A support plate 4029 is fixedly mounted on the top right end of the guide rail 401. The linkage shaft 4028 is rotatably mounted inside the support plate 4029. A first driving bevel gear 4030 is fixedly mounted on the right end of the linkage shaft 4028. A first driven bevel gear 4031 meshes with the outer periphery of the first driving bevel gear 4030. A torsion bar 4032 is fixedly mounted on the inner wall of the first driven bevel gear 4031. 032 The activity runs through the top and bottom of a longitudinal beam 3 located on the right side. A second driven bevel gear 5017 is fixedly installed at the rear end of a conveyor roller 509. A second driving bevel gear 5018 meshes with the outer periphery of the second driven bevel gear 5017. The second driving bevel gear 5018 is fixedly installed on the lower part of the outer wall of the twisting vertical rod 4032. A twisting block 5019 is rotatably sleeved on the bottom of the second driving bevel gear 5018 through a bearing. The twisting block 5019 is fixedly connected to the surface of the base 1.

[0046] In this embodiment, during the rotation of the output shaft of the servo motor 4023, the first active bevel gear 4030 is driven to rotate via the linkage shaft 4028. The rotation of the first active bevel gear 4030 drives the torsion bar 4032 to rotate via the first driven bevel gear 4031. The rotation of the torsion bar 4032 drives the second driven bevel gear 5017 to rotate via the second active bevel gear 5018. The rotation of the second driven bevel gear 5017 drives a connected conveyor roller 509 and pulley 5010 to rotate. Furthermore, under the support of the other conveyor roller 509 and pulley 5010 on the conveyor belt 5011, the conveyor belt 5011 rotates along the two pulleys 5010. The rotation of the conveyor belt 5011 drives multiple conveyor pallets 503 to rotate together. It should be noted that in this device, the moving speed of the enclosure plate 405 is always equal to the moving speed of the conveyor pallets 503. The worker then sequentially places the bearings that match the half-shaft specifications. One bearing is placed from the left end of the bearing carrier component 5 at the top center of the operating carrier pallet 503. As the bearing is transported to the right along with the carrier pallet 503, the carrier pallet 503 drives the two telescopic seats 505, the two clamping rods 506, and the two V-shaped clamps 507 to move together. When the two clamping rods 506 move between the two inclined planes 5015, they slide along the inner wall of the two inclined planes 5015. Under the wedge force of the two inclined planes 5015, the two clamping rods 506 move towards the center along the two telescopic seats 505, further pushing the two V-shaped clamps 507 towards the center, thus clamping the bearing placed on the top of the carrier pallet 503 and preventing the bearing from shifting. When the carrier pallet 503 has just transported the bearing to the bottom of the boss 4018, the half-shaft carrier component 4 drives the half-shaft to move downward, so that the bottom of the half-shaft is just inserted into the inner hole of the bearing, completing the automatic assembly of the bearing and the half-shaft.

[0047] Furthermore, each of the two transport frames 501 has a path groove 502 on one side that is close to each other. Two sliding pins 504 are fixedly installed on the front and back of the transport pallet 503. The outer wall of the sliding pin 504 is slidably connected to the inner wall of the path groove 502. When the transport belt 5011 drives the transport pallet 503 to move, the transport pallet 503 will drive the sliding pin 504 to move together, so that the sliding pin 504 slides along the inner wall of the path groove 502. Furthermore, through the sliding connection between the sliding pin 504 and the path groove 502, it plays a sliding support role for the transport pallet 503, ensuring the stability and strength of the transport pallet 503.

[0048] Furthermore, a return spring 508 is sleeved around the clamping top rod 506. The return spring 508 is fixedly installed between the telescopic seat 505 and the V-shaped clamping plate 507. When the clamping top rod 506 is pushed by the guide plate 5014 and moves towards the center, the two return springs 508 will be compressed and stored. The assembled half shaft continues to move to the right with the surrounding plate 405, causing the pressing top rod 4016 to slide to the right along the bottom of the boss 4018 until the top of the pressing top rod 4016 slides away from the bottom of the boss 4018. The two lifting springs 409 are elastically released, pushing the clamping seat 408 to slide upward along the two guide rods 407, thereby driving the two servo cylinders 4012 and the two telescopic plates 507. The shrinkage groove 4010, along with the assembled half-shaft and bearing, moves upward together. Simultaneously, the carrier plate 503 carrying the bearing moves to the right between the two guide plates 5014. The return force of the return spring 508 pushes the two clamping rods 506 and the two V-shaped clamps 507 to move in opposite directions, releasing the clamping effect on the bearing and facilitating the upward movement of the half-shaft carrying the bearing. When the assembled half-shaft and bearing move to the right end of the device, another worker holds the outer wall of the half-shaft and activates the two servo cylinders 4012 that clamp the half-shaft. This causes the output rods of the two servo cylinders 4012 to drive the two telescopic grooves 4010 to move in opposite directions, releasing the clamping effect on the half-shaft and making it easy to remove the half-shaft.

[0049] Example 3: Two light rods 5012, distributed left and right, are fixedly installed on the opposite sides of the two transport frames 501. An adjustment plate 5013 is slidably installed on the periphery of the two light rods 5012. A guide plate 5014 is fixedly installed on the upper part of the side of the adjustment plate 5013 near the transport frame 501. A positive and negative screw 5016 is rotatably installed between the two transport frames 501. The positive and negative screw 5016 moves through the two adjustment plates 5013 and is connected to the through holes of the two adjustment plates 5013 by a threaded engagement. The positive and negative screw 5016 is configured with front and rear reverse threads.

[0050] In this embodiment, by rotating the positive and negative lead screws 5016, the two adjusting plates 5013 move away from or towards each other under the action of the positive and negative threads and the threads of the two adjusting plates 5013. This causes the two guide plates 5014 to move together, adjusting the distance between the two guide plates 5014. This controls the moving distance of the two clamping rods 506 towards the center, and further adjusts the front and rear clamping distance of the two V-shaped clamping plates 507 to facilitate clamping bearings of different diameters. At the same time, the sliding connection between the adjusting plates 5013 and the guide rod 5012 ensures the stability of the adjusting plates 5013 and the guide plates 5014 during adjustment.

[0051] A new energy forklift half-shaft assembly device includes the following usage steps:

[0052] S1. Drive the half-shaft carrier component 4 and the bearing carrier component 5 to operate via the drive component;

[0053] S2. First, a worker places the half shaft to be assembled vertically inside one of the clamping seats 408 located on the left end. The output rods of the two servo cylinders 4012 push the two chucks 4011 towards the middle to clamp and fix the half shaft.

[0054] S3. At the same time, another worker places the bearing that matches the half shaft on top of the carrier plate 503 at the left end of the bearing carrier component 5.

[0055] S4. During the operation of the half-shaft transport component 4, multiple surrounding plates 405 rotate around the periphery of the guide rail 401, transporting the clamped half-shaft to the right. During this period, the bearing transport component 5 operates simultaneously, causing multiple transport pallets 503 to move between the two transport frames 501, transporting the bearing to the right.

[0056] S5. When the enclosure plate 405 moves the clamped half shaft to the bottom of the boss 4018, the boss 4018 pushes the clamping seat 408 downward along the two guide rods 407 through the convex surface thrust of the downward pressing rod 4016, thereby driving the half shaft clamped by the two chucks 4011 to move downward together, so that the bottom of the half shaft is just inserted into the bearing inner hole located directly below it, thus automatically completing the assembly of the half shaft and the bearing.

[0057] In this new energy forklift half-shaft assembly device, the servo motor 4023 is activated during operation. The output shaft of the servo motor 4023 drives the active synchronous pulley 4024 to rotate, which, under the transmission action of the synchronous belt 4026, drives the driven synchronous pulley 4025 along with the threaded rod 4021 to rotate. The rotation of the threaded rod 4021 generates a helical thrust, pushing a meshing pin 4027 to move. The movement of the pin 4027 causes the surrounding plates 405 and the slider 404 to move together. Since the surrounding plates 405 are all hinged by the torsion seat 4013 and the hinge rod 4014, the helical thrust of the threaded rod 4021 acts on any one of the pins 4027, allowing multiple surrounding plates 405 to rotate around the periphery of the guide rail 401. Because the surrounding plates 405 are all slidably connected to the track groove 403 via the slider 404, it ensures that the surrounding plates 405 move along the guide rail 401. The peripheral rotation is more stable. During the rotation of the output shaft of the servo motor 4023, the first active bevel gear 4030 is driven to rotate through the linkage shaft 4028. The rotation of the first active bevel gear 4030 drives the torsion bar 4032 to rotate through the first driven bevel gear 4031. The rotation of the torsion bar 4032 drives the second driven bevel gear 5017 to rotate through the second active bevel gear 5018. The rotation of the second driven bevel gear 5017 drives a connected conveyor roller 509 and pulley 5010 to rotate. Furthermore, under the support of the other conveyor roller 509 and pulley 5010 on the conveyor belt 5011, the conveyor belt 5011 rotates along the two pulleys 5010. The rotation of the conveyor belt 5011 drives multiple conveyor pallets 503 to rotate together. It should be noted that in this device, the moving speed of the enclosure plate 405 is always equal to the moving speed of the conveyor pallet 503.

[0058] Subsequently, one worker installs the half-shafts one by one from the left end of the half-shaft carrier component 4 into the inside of the operating clamping seat 408, that is, placing the half-shafts between the two chucks 4011. The output rods of the two servo cylinders 4012 push the two chucks 4011 towards the center to clamp and fix the half-shafts. The top of the half-shaft clamped between the two chucks 4011 must abut against the bottom of the fixing base 4015. Meanwhile, another worker places bearings matching the half-shaft specifications one by one from the left end of the bearing carrier component 5 at the top center of the operating carrier plate 503. As the bearings... During the transport of the pallet 503 to the right, the pallet 503 drives the two telescopic seats 505, the two clamping rods 506 and the two V-shaped clamps 507 to move together. When the two clamping rods 506 move between the two inclined planes 5015, they slide along the inner wall of the two inclined planes 5015. Under the wedge force of the two inclined planes 5015, the two clamping rods 506 move towards the middle along the two telescopic seats 505, further pushing the two V-shaped clamps 507 towards the middle, clamping the bearing placed on the top of the pallet 503 from front to back, preventing the bearing from shifting. During this period, the return spring 508 is compressed and stores force.

[0059] As the clamping seat 408 holding the half-shaft moves to the bottom of the boss 4018, it is pushed downward by the boss 4018 against the downward pressing rod 4016. This causes the clamping seat 408 to move downward along the two guide rods 407, resulting in the compression and storage of the two lifting springs 409. During the downward movement of the clamping seat 408, the two servo cylinders 4012 and the two telescopic grooves 4010 move downward, pushing the half-shaft of the clamped half-shaft downward. At the same time, the transport plate 503 transports the bearing to the bottom of the boss 4018. Therefore, when the half-shaft moves downward, its bottom just inserts into the inner hole of the bearing, thus completing the automatic assembly of the half-shaft and the bearing. After the assembly, the half-shaft continues to move to the right with the surrounding plate 405, causing the downward pressing rod 4016 to slide to the right along the bottom of the boss 4018 until the top of the downward pressing rod 4016 slides away from the boss 4018. At the bottom, the two lifting springs 409 are released elastically, pushing the clamping seat 408 to slide upward along the two guide rods 407. This, in turn, drives the two servo cylinders 4012, the two telescopic grooves 4010, and the assembled half-shaft and bearing to move upward together. At the same time, the carrier plate 503 carrying the bearing moves to the right from between the two guide plates 5014. The return force of the return spring 508 pushes the two clamping top rods 506 and the two V-shaped clamps 507 to move in opposite directions, releasing the clamping effect on the bearing and facilitating the half-shaft to carry the bearing upward. When the assembled half-shaft and bearing move to the right end of the device, another worker holds the outer wall of the half-shaft and activates the two servo cylinders 4012 that clamp the half-shaft. This causes the output rods of the two servo cylinders 4012 to drive the two telescopic grooves 4010 to move in opposite directions, releasing the clamping effect on the half-shaft, allowing the half-shaft to be removed.
