Description

Technical Field

[0001] This application relates to the technical field of synchronizers, and in particular to an automated production line for assembling and polishing synchronizers. Background Technology

[0002] In existing technologies, such as Figure 1 The synchronizer's gear ring assembly consists of an outer ring 11, a middle ring 12, and an inner ring 13. The inner side of the outer ring 13 and the outer side of the inner ring 11 (i.e., the side in contact with the middle ring) are pre-covered with a layer of carbon powder. Therefore, after assembling the outer ring 11, the middle ring 12, and the inner ring 13, the middle ring 12 needs to be rotated to grind the carbon powder layer. Existing equipment separates assembly and grinding. There is an urgent need for an automated production line for synchronizer assembly and grinding to ensure the quality and efficiency of synchronizer assembly and grinding. Summary of the Invention

[0003] To ensure the quality and efficiency of synchronizer assembly and polishing, this application provides an automated production line for synchronizer assembly and polishing.

[0004] This application provides an automated production line for assembling and grinding synchronizers, which adopts the following technical solution:

[0005] An automated production line for assembling and grinding synchronizers includes a machine body, a rotary conveyor, a feeding mechanism, a calibration mechanism, a testing mechanism, a grinding mechanism, an oil-slinging mechanism, and a discharging mechanism. Multiple tooling fixtures are arranged at intervals on the rotary conveyor. The feeding mechanism sequentially picks up an outer ring, a middle ring, and an inner ring and places them onto the tooling fixtures to assemble a gear assembly. The calibration mechanism moves downward and presses against the gear assembly under elastic force. The calibration mechanism rotates, engaging with the middle ring to drive the middle ring to rotate and achieve gear assembly calibration.

[0006] The detection mechanism is used to detect the height of the calibrated gear assembly and remove unqualified gear assemblies; the grinding mechanism is used to grind qualified gear assemblies and spray cooling oil for cooling; the oil-slinging mechanism is used to remove residual cooling oil from the gear assembly; and the unloading mechanism is used to transport the gear assembly after removing the cooling oil off the production line.

[0007] By adopting the above technical solution, multiple toolings are placed on the rotary production line and the movement of multiple toolings is realized. The feeding mechanism sequentially places the outer ring, middle ring and inner ring on the tooling to realize assembly. The tooling moves forward to the correction mechanism, and the feeding mechanism continues to feed the next tooling. The correction mechanism moves down to press against the inner ring and middle ring. The correction mechanism rotates to drive the middle ring to rotate after it is inserted with the middle ring. If there is a problem with the assembly of the gear assembly, the gear assembly can be more accurately assembled under the dual action of the correction mechanism's squeezing and rotation. At the same time, the middle ring can also be initially ground. Then the correction mechanism moves up and rotates back to its original position.

[0008] The tooling and gear assembly continue to move forward. The inspection mechanism checks the height of the gear assembly. If there is a problem with the assembly of the gear assembly, and the height of the gear assembly exceeds the specified value, the inspection mechanism will detect it as unqualified and remove it. The qualified gear assembly moves forward to the grinding mechanism. The grinding mechanism starts pressing the inner ring and driving the middle ring to rotate, thereby completing the grinding of the gear assembly. Cooling oil is sprayed during grinding, making the grinding faster and with better quality. The grinding mechanism separates from the gear assembly. The ground gear assembly moves to the oil-throwing mechanism. The oil-throwing mechanism starts to remove the residual cooling oil on the gear assembly. Then the gear assembly moves to the unloading mechanism. The unloading mechanism starts to convey the gear assembly off the line, thus completing the assembly and grinding of the gear assembly.

[0009] By using a rotary production line to drive the tooling movement and coordinating multiple structures, the assembly, calibration, inspection, grinding, degreasing, and final unloading of gear components are automated, ensuring the quality and efficiency of synchronizer assembly and grinding. The calibration mechanism ensures more accurate gear assembly and positions the intermediate ring, facilitating faster rotation of the intermediate ring by the grinding mechanism and further improving grinding efficiency. Since grinding takes the most time compared to other processes, it is divided into initial and final grinding stages. This prevents overall efficiency from being reduced due to multiple processes waiting for grinding. Furthermore, the use of cooling oil spray during grinding further enhances grinding quality and efficiency, thus further improving the quality and efficiency of synchronizer assembly and grinding.

[0010] Optionally, the grinding mechanism includes:

[0011] The grinding base is vertically slidably mounted on the machine body;

[0012] A rotating base is rotatably mounted on a grinding base;

[0013] The pressing component is rotatably mounted on the rotating seat and, after moving down, presses against the inner ring under the action of elasticity for positioning and alignment.

[0014] The rotating component is mounted on the rotating seat and, under the action of elasticity, it is inserted and engaged with the intermediate ring for positioning and drives the intermediate ring to rotate to achieve grinding;

[0015] A blocking component is used to position or unlock the tooling that has been moved below the grinding stand;

[0016] The lifting component is used to vertically push the tooling after positioning to move and to detach the tooling from the rotary production line or to place the tooling onto the rotary production line.

[0017] The oil spray pipe sprays cooling oil onto the gear assembly.

[0018] By adopting the above technical solution, the blocking component moves to the top of the rotary production line. When the tooling moves to the bottom of the grinding seat, it abuts against the blocking component for positioning. The lifting component then moves upward to lift the tooling, disengaging it from the rotary production line, and the blocking component unlocks its positioning of the tooling. The grinding seat and rotating seat move downward, driving the pressing component and rotating component to move downward simultaneously. The pressing component presses against the inner ring for positioning, while the inner ring presses against the outer ring, preventing the inner and outer rings from rotating. The rotating component engages with the intermediate ring. The grinding seat rotates, driving the rotating component and intermediate ring to rotate simultaneously, and the oil spray pipe sprays cooling oil towards the gear assembly, thereby achieving the grinding of the gear assembly. After grinding, the grinding seat, pressing component, and rotating component move upward simultaneously to disengage from the gear assembly. At the same time, the lifting component moves downward to place the tooling on the rotary production line. The tooling moves forward under the drive of the rotary production line, and then the blocking component continues to move back to the top of the rotary production line to position the next tooling, and then the grinding process is repeated.

[0019] The lifting assembly elevates the tooling above the rotary production line, allowing the production line to move during grinding without stopping, thus reducing the risk of damage caused by frequent start-stop cycles. Simultaneously, the lifting assembly positions the tooling, resulting in more accurate and stable grinding. The pressure from the pressing assembly further improves the assembly quality of the gear assembly's multiple components, enhancing the quality and efficiency of synchronizer assembly and grinding. Furthermore, the rotating connection between the pressing assembly and the rotating base ensures that the rotating base's rotation does not interfere with the pressing assembly's positioning of the gear assembly, further improving the quality and efficiency of synchronizer assembly and grinding.

[0020] Optionally, the pressure-absorbing component includes:

[0021] The sliding column is rotatably mounted on a rotating seat and is positioned with a first blocking plate;

[0022] The mounting plate is mounted on the sliding column;

[0023] The first positioning post is vertically slidably mounted on the sliding post and is provided with a second blocking plate. The second blocking plate has a cone-shaped positioning surface that can be inserted and positioned with the inner side wall of the inner ring.

[0024] The second positioning post is vertically slidably disposed on the first positioning post and both the first and second positioning posts are connected to the mounting plate through the first elastic element. In the initial state, under the elastic force of the first elastic element, the first positioning post presses against the first blocking plate and the second positioning post presses against the second blocking plate for positioning. The grinding seat moves down and the positioning surface is inserted and installed on the inner side wall of the inner ring for positioning and alignment, and the second positioning post presses against the top of the inner ring for positioning.

[0025] By adopting the above technical solution, the pressing component moves downward, allowing the positioning surface to first fit against the inner wall of the inner ring for positioning, thereby achieving overall positioning and alignment of the gear assembly. Then, the second positioning post moves downward and presses against the top of the inner ring for positioning, so that both the inner and outer rings are positioned. The conical positioning surface can better achieve overall positioning and alignment of the gear assembly. Finally, the second positioning post can better press the inner and outer rings to prevent displacement, thereby improving the efficiency and accuracy of grinding, and improving the quality and efficiency of synchronizer assembly and grinding.

[0026] After grinding is completed, the pressing component moves upward, and the first positioning post and the second positioning post move back and press against the first blocking plate and the second blocking plate respectively for positioning.

[0027] Optionally, the rotating assembly includes:

[0028] A rotating ring is vertically slidably mounted on a rotating seat and is equipped with a rotating block;

[0029] The guide post is detachably mounted on the rotating seat and vertically slidably connected to the rotating ring;

[0030] The retaining ring is detachably mounted on the rotating base.

[0031] The second elastic element is sleeved on the guide post and its two ends press against the rotating seat and the retaining ring. Under the action of elastic force, it pushes the rotating ring against the retaining ring for positioning, so that the rotating block is inserted and installed on the middle ring for positioning and the middle ring and the rotating block rotate simultaneously.

[0032] By adopting the above technical solution, the rotating seat drives the rotating assembly to move downward, so that the rotating block is inserted and installed on the intermediate ring. At the same time, the rotating block continues to move downward and presses against the intermediate ring under the elastic force of the second elastic element, so that the intermediate ring and gear assembly are assembled in place. Then, the rotating seat rotates to drive the rotating ring and the rotating block to rotate simultaneously, driving the intermediate ring to rotate to achieve grinding. After grinding is completed, the rotating assembly drives the rotating assembly to move upward, and the rotating ring moves back to press against the retaining ring for positioning, thereby driving the intermediate ring to rotate.

[0033] Optionally, the lifting component includes:

[0034] The lifting plate is vertically slidably mounted on the machine body;

[0035] Lifting components are used to drive the lifting plate to move vertically.

[0036] Multiple positioning components are spaced apart on the lifting plate and have guide angles to facilitate insertion and mating with tooling.

[0037] By adopting the above technical solution, the lifting component drives the lifting plate to move. The lifting plate moves up and drives multiple positioning components to approach the tooling. Under the action of the guide angle, the multiple positioning components are inserted and installed on the tooling for positioning. At the same time, the tooling is aligned so that it can be aligned with the pressing component and the rotating component. The lifting plate drives the tooling to disengage from the rotary production line and then grind it. After grinding, the lifting plate moves down and the tooling is placed on the rotary production line. The lifting plate continues to move down and the multiple positioning components disengage from the tooling. The tooling continues to move forward under the action of the rotary production line, which improves the quality and efficiency of synchronizer assembly and grinding.

[0038] Optionally, the blocking component includes:

[0039] The blocking block is rotatably mounted on the machine body via a rotating shaft, with both ends positioned along the tooling movement direction.

[0040] The blocking wheel is rotatably mounted on one end of the blocking block and abuts against the tooling for positioning;

[0041] A blocking component is installed on the machine body with the piston rod vertically upward;

[0042] The torsion component is connected to the blocking block and the machine body, and under the action of elastic force, the end of the blocking block away from the blocking wheel presses against the piston rod of the blocking component.

[0043] By adopting the above technical solution, the blocking block presses against the piston rod of the blocking component under the torque of the torque component. When the piston rod of the blocking component retracts, the blocking block rotates under the action of the torque component, causing the blocking wheel to rotate above the rotary production line, so that the tooling abuts against the blocking wheel for positioning. When the tooling moves upward, it drives the blocking wheel to rotate. The piston rod of the blocking component extends and pushes the blocking block to rotate, so that both the blocking wheel and the blocking block rotate below the rotary production line, so that the tooling can move under the action of the rotary production line.

[0044] Optionally, the oil-throwing mechanism includes:

[0045] An oil slinger is installed on the first frame and is used to collect cooling oil.

[0046] The shaft is rotatably mounted on the frame and extends into the oil slinger and is rotatably connected to the oil slinger.

[0047] An oil slinger is mounted on the shaft and located inside the oil slinger bucket, and has an oil slinger groove for placing the gear assembly.

[0048] The material gripping assembly is used to grip and place the gear assembly located on the rotary production line onto the oil slinger.

[0049] The sealing assembly is used to press against the top of the oil slinger to seal it and to position it against the gear assembly, or to be moved to the outside of the oil slinger for easy transport of the gear assembly.

[0050] By adopting the above technical solution, the material gripping component picks up the gear assembly located on the tooling and places it on the oil slinger for positioning. The sealing component is activated to seal the top of the oil slinger and press against the gear assembly for positioning. The shaft rotates to drive the gear assembly and the sealing component to rotate, thereby causing the cooling oil on the gear assembly to fall off under the action of centrifugal force. The sealing component is activated to move away from the oil slinger, and the unloading mechanism is activated to pick up the gear assembly located on the oil slinger and place it on a tray for transfer. This achieves the removal and recycling of the cooling oil on the gear assembly, improving the quality and efficiency of synchronizer assembly and grinding.

[0051] Optionally, the material gripping assembly includes:

[0052] Material gripper one is horizontally slidably mounted on frame two;

[0053] The second gripper seat is vertically slidably mounted on the first gripper seat;

[0054] The gripper is used to grip the gear assembly.

[0055] By adopting the above technical solution, gripper seat one drives gripper to move horizontally, and gripper seat two drives gripper to move vertically. The gripper is used to grip and transport the gear assembly.

[0056] Optionally, the plugging assembly includes:

[0057] Movable seat one is slidably mounted on frame three in the direction of approaching or moving away from the oil slinger;

[0058] The second movable seat is vertically slidably mounted on the first movable seat;

[0059] The cover is mounted on the second material gripper.

[0060] The pressing component is rotatably mounted on the cover; when the cover moves down and abuts against the oil slinger to seal it, the pressing component presses against the gear assembly for positioning and rotates simultaneously with the gear assembly.

[0061] By adopting the above technical solution, the moving seat drives the cover and the pressing part to move horizontally to directly above the oil slinger. The cover and the pressing part move downward, the cover presses against the top of the oil slinger to seal it, and the pressing part presses against the gear assembly for positioning. The shaft rotates to drive the gear assembly and the pressing part to rotate simultaneously, thereby removing the cooling oil located on the gear assembly.

[0062] Optionally, the testing organization includes:

[0063] A detector used to detect the height of gear assemblies;

[0064] The NG feeding channel is electrically connected to the detector to pick up defective products.

[0065] The NG collection platform is used to collect defective products captured by the NG unloading channel.

[0066] By adopting the above technical solution, the detector is used to detect the height of the gear assembly. If the height is higher than the specified height, it indicates that the gear assembly is unqualified. The NG unloading channel is activated to grab the unqualified gear assembly and transport it to the NG collection platform. The staff intervenes to re-inspect the gear assembly and carry out subsequent processing, thereby removing the unqualified gear assembly.

[0067] In summary, this application includes at least one of the following beneficial technical effects:

[0068] 1. The automatic assembly line operation of gear components includes loading, assembly, calibration, inspection, grinding, degreasing, and final unloading. The calibration mechanism makes the gear assembly more accurate and can position the intermediate ring, which makes it easier for the grinding mechanism to drive the intermediate ring to rotate more quickly, thereby ensuring the quality and efficiency of synchronizer assembly and grinding.

[0069] 2. By dividing the grinding process into two stages, the initial grinding and the final grinding, the overall efficiency is not reduced due to multiple processes waiting for grinding. Furthermore, the grinding quality and efficiency are further improved by spraying cooling oil during grinding, thus further improving the quality and efficiency of synchronizer assembly and grinding.

[0084] The following provides a further detailed description of this application.

[0085] This application discloses an automated production line for assembling and grinding synchronizers.

[0086] Example 1, referring to Figures 1-2 The synchronizer assembly and grinding automated production line includes a body 18, a rotary conveyor 21, a feeding mechanism 22, a calibration mechanism 29, a detection mechanism 8, a grinding mechanism 3, an oil-throwing mechanism 9, and a discharging mechanism 23. Multiple tooling fixtures 14 are arranged at intervals on the rotary conveyor 21. The rotary conveyor 21 drives the multiple tooling fixtures 14 to pass through the feeding mechanism 22, the calibration mechanism 29, the detection mechanism 8, the grinding mechanism 3, and the oil-throwing mechanism 9 in sequence before moving back to the feeding mechanism 22.

[0087] The feeding mechanism 22 is used to sequentially pick up the outer ring 11, the middle ring 12 and the inner ring 13 and place them on the tooling 14 to assemble the gear assembly 1; the correction mechanism 29 moves down and presses against the gear assembly 1 under the action of elasticity. The correction mechanism 29 rotates and makes it fit into the gear assembly 1 for positioning, and is used to correct the gear assembly 1; the detection mechanism 8 is used to detect the height of the corrected gear assembly 1 and remove unqualified gear assemblies 1; the grinding mechanism 3 is used to grind qualified gear assemblies 1 and spray cooling oil for cooling; the oil slinging mechanism 9 is used to remove the residual cooling oil on the gear assembly 1; the unloading mechanism 23 is used to convey the gear assembly 1 after the cooling oil has been removed off the production line.

[0088] Reference Figures 2-3 The rotary conveyor line 21 includes two parallel conveying sections and arc segments at both ends of the two conveying sections to achieve an elliptical loop shape. At the same time, two rotary conveyor lines 21 are arranged at intervals and installed on the machine body 18, with one rotary conveyor line 21 located inside the other rotary conveyor line 21. The tooling 14 is placed on the two rotary conveyor lines 21 at both ends for conveying. At the same time, two or more mounting slots are opened on one tooling 14 as needed. One mounting slot realizes the assembly of one gear assembly 1, thereby realizing the assembly of two or more gear assemblies 1.

[0089] Reference Figures 1-2 The feeding mechanism 22 is arranged in three sets at intervals, which respectively realize the conveying of the outer ring 11, the middle ring 12 and the inner ring 13. The feeding mechanism 22 first grabs the outer ring 11 and places it on the mounting slot for positioning. The tooling 14 and the outer ring 11 move forward, and then the middle ring 12 and the inner ring 13 are put in sequentially, so that the middle ring 12 is inserted into the outer ring 11 and the top end extends above the outer ring 11. The inner ring 13 is inserted into the middle ring 12 and the inner ring 13 is inserted into the outer ring 11 to complete the assembly of the gear assembly 1. At the same time, each feeding mechanism 22 can realize the conveying of multiple rings. The number of rings is the same as the number of mounting slots, that is, multiple gear assemblies 1 can be assembled. The feeding mechanism 22 adopts the structure of the prior art, which will not be described in detail here.

[0090] Reference Figure 2, Figures 4-8 The grinding mechanism 3 includes a grinding seat 31, a rotating seat 32, a pressing component 4, a rotating component 5, a blocking component 7, a lifting component 6, and an oil injection pipe 33. A mounting bracket 15 extending above the rotary production line 21 is fixedly installed on the machine body 18. The grinding seat 31 is vertically slidably installed on the mounting bracket 15. A driving component for driving the grinding seat 31 to move vertically is fixedly installed on the mounting bracket 15. The driving component can be a motor screw nut structure or an electric push rod structure, which can be selected as needed to achieve the vertical movement of the grinding seat 31.

[0091] The rotating base 32 is rotatably mounted on the grinding base 31 via the rotating column 36. The rotating column 36 is rotatably mounted on the grinding base 31 and is in a vertical position. A servo motor that drives the rotating column 36 to rotate is fixedly mounted on the grinding base 31. The rotating base 32 includes a rotating head 34 and a rotating cylinder 35. The rotating head 34 is coaxially fixedly mounted on the top and bottom ends of the rotating column 36. The rotating cylinder 35 is fixedly mounted on the bottom end of the rotating head 34 by screws, and the rotating cylinder 35 is coaxially arranged with the rotating head 34.

[0092] Reference Figures 3-8 The pressing component 4 is rotatably mounted on the rotating head 34 and, after moving down, presses against the inner ring 13 under the action of elasticity for positioning. The rotating component 5 is set on the rotating seat 32 and, under the action of elasticity, engages with the intermediate ring 12 for positioning and is used to drive the intermediate ring 12 to rotate to achieve grinding. The blocking component 7 is used to position or unlock the tooling 14 that has moved to the bottom of the grinding seat 31. It is used to vertically push the positioned tooling 14 upward and disengage it from the rotary conveyor line 21, or to move it downward and place the tooling 14 on the rotary conveyor line 21 for conveying. The oil spray pipe 33 is fixedly mounted on the mounting bracket 15 and is used to spray cooling oil onto the gear assembly 1 to cool or lubricate the intermediate ring 12.

[0093] The blocking component 7 moves above the rotary production line 21, and the tooling 14 and gear assembly 1 move below the grinding seat 31. The tooling 14 is positioned against the blocking component 7. The lifting component 6 pushes the tooling 14 upward to disengage from the rotary production line 21, and the blocking component 7 moves below the rotary production line 21 to unlock, without obstructing the movement of the tooling 14. At the same time, the grinding seat 31 drives the rotating seat 32, the pressing component 4, and the rotating component 5 to move downward. The pressing component 4 presses against the inner ring 13 and positions the inner ring 13 and the outer ring 11.

[0094] The rotating component 5 is inserted and installed on the intermediate ring 12 and pressed against the intermediate ring 12 for positioning. The rotating seat 32 rotates to drive the rotating component 5 and the intermediate ring 12 to rotate to achieve grinding. At the same time, the oil spray pipe 33 sprays cooling oil onto the gear assembly 1, with more cooling oil directed towards the intermediate ring 12. After grinding, the grinding seat 31 drives the pressing component 4 and the rotating component 5 to move upward, and the lifting component 6 drives the tooling 14 to move downward, so that the tooling 14 is placed on the rotary production line 21 for conveying. The blocking component 7 moves above the rotary production line 21 to continue grinding the gear assembly 1 located on the next tooling 14.

[0095] Reference Figures 5-7 The pressing component 4 includes a sliding column 41, a mounting plate 42, a first positioning column 43, and a second positioning column 44, all coaxially arranged. The sliding column 41 is coaxially rotatably mounted on the bottom end of the rotating head 34, and its bottom end coaxially passes through the rotating cylinder 35 and extends below the rotating cylinder 35. The bottom end of the sliding column 41 is coaxially fixedly mounted with a first blocking plate 45 by screws. The mounting plate 42 is fixedly mounted on the sliding column 41, and the mounting plate 42 is located inside the rotating cylinder 35 and between the first blocking plate 45 and the rotating head 34. The first positioning column 43 is vertically slidably mounted on the sliding column 41, and the outer wall of the bottom end of the first positioning column 43 is coaxially and integrally provided with a second blocking plate 46. The bottom end of the second blocking plate 46 has a positioning surface 48, which is conical and fits against the inner wall of the inner ring 13 and is interlocked for positioning.

[0096] The second positioning post 44 is vertically slidably sleeved on the first positioning post 43. The first positioning post 43 and the mounting plate 42, and the second positioning post 44 and the mounting plate 42 are all connected by the first elastic element 47, which is a spring. The first positioning post 43, the mounting plate 42 and the second positioning post 44 are all provided with multiple grooves for limiting the first elastic element 47. In the initial state, under the action of the elastic force of the first elastic element 47, the first positioning post 43 presses against the first blocking plate 45 and the second positioning post 44 presses against the second blocking plate 46 for positioning.

[0097] The rotating assembly 5 includes a rotating ring 51, a guide post 52, a retaining ring 53, and a second elastic element 54. The inner and outer side walls of the rotating ring 51 are vertically slidably installed on the outer side wall of the second positioning post 44 and the inner side wall of the rotating cylinder 35, respectively. The top of the rotating ring 51 is located inside the rotating cylinder 35 and the bottom end extends below the rotating cylinder 35. A plurality of rotating blocks 55 are spaced apart at the bottom end of the rotating ring 51. The rotating blocks 55 are used to engage with the slots located on the intermediate ring 12. The number and shape of the rotating blocks 55 are designed according to the intermediate ring 12.

[0098] The guide post 52 is threaded onto the rotating cylinder 35. The rotating ring 51 has a sliding groove along its own axis, and the guide post 52 extends into the sliding groove and slides into the sliding groove. The retaining ring 53 is fixedly installed on the bottom end of the rotating cylinder 35 by screws. The second elastic element 54 is a spring. The two ends of the second elastic element 54 press against the opposite side walls of the rotating cylinder 35 and the rotating ring 51. Multiple second elastic elements 54 and guide posts 52 are arranged in a circumferential array around the axis of the rotating cylinder 35. The second elastic element 54 is in a compressed state. In the initial state, the rotating ring 51 is pressed against the retaining ring 53 for positioning under the action of elastic force.

[0099] The grinding seat 31 moves downward, driving the rotating assembly 5 and the pressing assembly 4 to move downward simultaneously. This allows the positioning surface 48 to be first inserted and installed on the inner wall of the inner ring 13 for positioning and aligning the gear assembly 1 as a whole. The grinding seat 31 continues to move downward, causing the bottom end of the second positioning post 44 to press against the top of the inner ring 13 for positioning. Since the inner ring 13 presses against the outer ring 11, both the inner ring 13 and the outer ring 11 can be positioned simultaneously. At the same time, multiple rotating blocks 55 are inserted and engaged with the intermediate ring 12, and the rotating blocks 55 press against the intermediate ring 12 for positioning. The grinding seat 31 continues to move downward, increasing the squeezing force on the first elastic element 47 and the second elastic element 54, thereby increasing the positioning effect of the inner ring 13 and the outer ring 11, and also increasing the stability of the rotating blocks 55 after they are connected to the intermediate ring 12.

[0100] The rotating seat 32 rotates to drive the rotating block 55 and the intermediate ring 12 to rotate to achieve grinding. After grinding is completed, the grinding seat 31 moves upward to drive the pressing component 4 and the rotating component 5 to move upward and disengage from the gear component 1, so that the first positioning post 43 presses against the first blocking plate 45, the second positioning post 44 presses against the second blocking plate 46, and the rotating ring 51 presses against the retaining ring 53 for positioning.

[0101] Reference Figures 3-4 , Figure 8 Mounting bracket 2 16 and mounting bracket 3 17 are fixedly installed at intervals on the machine body 18 along the moving direction of tooling 14. Mounting bracket 2 16 and mounting bracket 3 17 are located between two rotary conveyor lines 21 and below the rotary conveyor lines 21. Lifting component 6 is fixedly installed on mounting bracket 2 16, and blocking component 7 is fixedly installed on mounting bracket 3 17.

[0102] The lifting assembly 6 includes a lifting plate 61, a lifting component 62, and multiple positioning components 63. The lifting plate 61 is vertically slidably mounted on the mounting bracket 16 and is in a horizontal state. The lifting component 62 is an electric actuator or hydraulic cylinder, etc. The lifting component 62 is fixedly mounted on the lower surface of the mounting bracket 16 with its piston rod facing upward. The piston rod of the lifting component 62 is fixedly connected to the lifting plate 61 and is used to drive the lifting plate 61 to move vertically. Multiple positioning components 63 are fixedly mounted at intervals on the upper surface of the lifting plate 61. The positioning components 63 are vertically upward and have a guide angle 64 at the top of the positioning component 63 to facilitate insertion with the tooling 14. The lower surface of the tooling 14 has an insertion groove for insertion with the positioning component 63.

[0103] When the lifting plate 61 moves upward, the guide angle 64 can easily extend into the insertion slot. Under the guidance of the guide angle 64, multiple positioning parts 63 are aligned with multiple insertion slots respectively, so that multiple positioning parts 63 are inserted and installed on multiple insertion slots for positioning. The lifting plate 61 is supported on the lower surface of the tooling 14, pushing the tooling 14 to disengage from the rotary conveyor line 21. At the same time, the lifting plate 61 moves downward, so that the tooling 14 can be placed on the two rotary conveyor lines 21, and the multiple positioning parts 63 disengage from the insertion slots. The rotary conveyor line 21 realizes the conveying of the tooling 14.

[0104] The blocking assembly 7 includes a blocking block 71, a blocking wheel 72, a blocking element 73, and a torque element. The blocking block 71 is rotatably mounted on the mounting bracket 17 via a rotating shaft, with both ends of the blocking block 71 extending to both sides of the rotating shaft along the moving direction of the tooling 14. The blocking wheel 72 is rotatably mounted on the end of the blocking block 71 near the lifting assembly 6, and the blocking wheel 72 is in a horizontal state. The blocking element 73 is an electric actuator, which is fixedly mounted on the mounting bracket 17, and the piston rod of the blocking element 73 extends vertically upward to below the end of the blocking block 71 away from the blocking wheel 72. The torque element is a torsion spring, which is sleeved on the rotating shaft and has both ends fixedly connected to the blocking block 71 and the mounting bracket 17, respectively, so that the end of the blocking block 71 away from the blocking wheel 72 is pressed against the piston rod of the blocking element 73 for positioning under the torque of the torque element.

[0105] When the piston rod of the blocking component 73 retracts, the blocking block 71 rotates under the torque of the torque component, causing the blocking wheel 72 to rotate above the rotary conveyor 21. The fixture 14 approaches and abuts against the blocking wheel 72 for positioning under the action of the rotary conveyor 21. After the fixture 14 moves upward and disengages from the rotary conveyor 21, the piston rod of the blocking component 73 extends, driving the blocking block 71 to rotate, causing the blocking wheel 72 to rotate below the rotary conveyor 21. Therefore, when the fixture 14 is placed on the rotary conveyor 21, it moves directly under the driving action of the rotary conveyor 21. After the fixture 14 moves forward, the piston rod of the blocking component 73 retracts, causing the blocking wheel 72 to rotate above the rotary conveyor 21, thereby continuing to block the movement of the next fixture 14.

[0106] Reference Figure 2 , Figure 4 , Figure 5 The correction mechanism 29 is the same as the grinding mechanism 3, except that the correction mechanism 29 does not have an oil spraying structure. When the correction mechanism 29 moves down, it first inserts into the inner ring 13 for positioning. The pressure of the correction mechanism 29 on the middle ring 12 is small. The rotation of the correction mechanism 29 will not drive the middle ring 12 to rotate. After the correction mechanism 29 rotates and extends under the action of elasticity, it inserts into the middle ring 12. The correction mechanism 29 continues to move down, so that after it is inserted into the middle ring 12, it drives the middle ring 12 to rotate, thereby enabling the positioning of the middle ring 12. This allows the rotating block 55 to be inserted into the middle ring 12 more accurately and conveniently. Therefore, it will not be described in detail here.

[0107] Reference Figure 1 , Figure 2 , Figure 9 The inspection mechanism 8 includes a detector, an NG unloading channel 82, and an NG collection platform 83. The detector is fixedly mounted on the body 18 and faces the fixture 14. The detector is used to detect the height of the gear assembly 1 located on the fixture 14. If the height of the gear assembly 1 is higher than a specified height, the gear assembly 1 is a defective product; otherwise, the gear assembly 1 is a qualified product. The NG collection platform 83 is fixedly mounted on the body 18 and is horizontal. The NG unloading channel 82 is electrically connected to the detector. The NG unloading channel 82 is used to grab and transport the defective gear assembly 1 to the NG collection platform 83. Workers intervene to inspect and process the gear assembly 1 located on the NG collection platform 83. The NG unloading channel 82 is a structure in the prior art and can be a robotic arm or a sliding gripper structure, etc., which will not be described in detail here.

[0108] Reference Figure 2 , Figure 3 , Figure 10 The oil-throwing mechanism 9 includes an oil-throwing tank 91, a shaft 92, an oil-throwing seat 93, a material-grabbing assembly 94, and a sealing assembly 95. Frame 1 26, Frame 27, and Frame 3 28 are fixedly installed at intervals on the machine body 18. The tooling 14 passes through Frame 3 28, Frame 27, and Frame 1 26 in sequence. Two oil-throwing tanks 91, two shafts 92, and two oil-throwing seats 93 are provided and used to remove cooling oil from the two gear assemblies 1 located on the tooling 14. The oil-throwing tank 91 is fixed. The gear assembly 1 is mounted on the upper surface of the frame 28 and is vertically arranged; the shaft 92 passes through the frame 28 and the oil slinger 91 and extends into the oil slinger 91. The shaft 92 is coaxially arranged with the oil slinger 91 and is rotatably connected to the oil slinger 91 and the frame 28. The oil slinger seat 93 is coaxially fixedly installed on the top of the shaft 92 and located inside the oil slinger 91. The oil slinger seat 93 is provided with an oil slinger groove for placing the gear assembly 1. The oil slinger 91 is provided with an output pipe 931 for outputting cooling oil.

[0109] Reference Figure 3 , Figures 10-11The material gripping assembly 94 is used to grip and place the gear assembly 1 located on the rotary production line 21 onto the oil slinger. The material gripping assembly 94 includes a first gripping seat 941, a second gripping seat 942, and a gripping component 943. The first gripping seat 941 is horizontally slidably mounted on the second frame 27, and the second gripping seat 942 is vertically slidably mounted on the side wall of the first gripping seat 941. Both the second frame 27 and the first gripping seat 941 are fixedly mounted with driving components. The two driving components drive the first gripping seat 941 and the second gripping seat 942 to move respectively. The driving components can be electric push rods. The gripping component 943 includes multiple jaws and a driving component. The multiple jaws are radially slidably mounted on the bottom of the second gripping seat 942 along the oil slinger 91, and the driving component is used to drive the multiple jaws to move away from or towards each other.

[0110] Reference Figures 2-3 , Figures 10-11 The driving component drives multiple grippers to move away from each other. The gripper base 1 941 and gripper base 2 942 move and drive the gripper 943 to move to the gear assembly 1 located on the tooling 14. The driving component drives multiple grippers to move closer to each other to clamp the gear assembly 1. The gripper base 1 941 and gripper base 2 942 drive the gripper 943 and the gear assembly 1 to move and place the gear assembly 1 on the oil slinger. The multiple grippers move away from each other to release the clamping. The gripper base 1 941 and gripper base 2 942 drive the gripper 943 to move away from the gear assembly 1.

[0111] The sealing assembly 95 includes a first movable seat 951, a second movable seat 952, a cover 953, and a pressing member 954. The first movable seat 951 is horizontally slidably mounted on the first frame 26, and the first movable seat 951 is positioned close to or away from the oil slinger 91. The second movable seat 952 is vertically slidably mounted on the end of the first movable seat 951 close to the oil slinger 91. Both the first frame 26 and the first movable seat 951 are equipped with driving members for driving the first movable seat 951 and the second movable seat 952 to move. The cover 953 is fixedly mounted on the lower surface of the second movable seat 952, and a pressing shaft 955 extending into the cover 953 is vertically rotatably mounted on the second movable seat 952. The pressing shaft 955 is rotatably connected to the cover 953.

[0112] When the cover 953 abuts against the top of the oil slinger 91 to seal, the bearings of the cover 953 and the oil slinger 91 coincide; the pressing member 954 is fixedly installed on the pressing shaft 955 and located inside the cover 953, and the pressing member 954 presses against the gear assembly 1 for positioning.

[0113] After the material grabbing assembly 94 places the gear assembly 1 onto the oil slinger, the first moving seat 951 drives the second moving seat 952 and the cover 953 to move directly above the oil slinger 91. The second moving seat 952 drives the cover 953 and the pressing member 954 to move downward, so that the cover 953 presses against the top of the oil slinger 91 to seal the oil slinger 91, and the pressing member 954 presses against the gear assembly 1 for positioning. A motor that drives the shaft 92 to rotate is fixedly installed on the frame 26. When the motor starts, it drives the shaft 92 to rotate. The rotation of the shaft 92 drives the oil slinger 93, the gear assembly 1, and the pressing member 954 to rotate, so that the cooling oil on the gear assembly 1 falls off under centrifugal force.

[0114] The second moving seat 952 drives the cover 953 and the pressing member 954 to move upwards above the oil slinger 91, while the first moving seat 951 drives the cover 953 and the pressing member 954 to move horizontally away from the oil slinger 91. The unloading mechanism 23 includes a robot arm 24 and a conveyor belt 25. Multiple pallets are placed on the conveyor belt 25. The robot arm 24 grabs the gear assembly 1 after removing the cooling oil and places it into the pallet. At the same time, the staff collects the pallets on the conveyor belt 25, thereby completing the unloading of the gear assembly 1.

[0115] The working principle of this application embodiment is as follows:

[0116] The rotary conveyor 21 transports multiple tooling fixtures 14 in a loop-shaped movement. The tooling fixtures 14 move to the feeding mechanism 22, which sequentially places the outer ring 11, the middle ring 12, and the inner ring 13 into the mounting slots on the tooling fixtures 14 to assemble the gear assembly 1. The tooling fixtures 14 move to the calibration mechanism 29, which moves down and presses against the inner ring 13 under elastic force. At the same time, the calibration mechanism 29 presses against the middle ring 12. The calibration mechanism 29 rotates to engage with the middle ring 12. The calibration mechanism 29 continues to rotate to pre-grind the gear assembly 1, and then stops to position the middle ring 12. The tooling fixtures 14 move to the detection mechanism 8, where the detector detects the height of the gear assembly 1. The NG unloading channel 82 picks up the defective gear assembly 1 and places it on the NG collection platform 83 to remove the defective gear assembly 1.

[0117] Tooling 14 moves to abut against blocking wheel 72 for positioning. Lifting component 6 pushes tooling 14 upward and disengages it from rotary production line 21. At the same time, grinding seat 31 moves downward, driving pressing component 4 and rotating component 5 to move downward, so that positioning surface 48 first inserts into the inner wall of inner ring 13 for positioning and alignment. Second positioning post 44 presses against inner ring 13 for positioning. Rotating block 55 is inserted into intermediate ring 12 for positioning. Rotating seat 32 rotates, driving rotating block 55 and intermediate ring 12 to rotate, thereby turning intermediate ring 12 to achieve grinding. At the same time, oil spray pipe 33 sprays cooling oil onto gear assembly 1. Blocking component 73 starts to drive blocking wheel 72 to rotate below rotary production line 21.

[0118] After grinding is completed, the oil injection pipe 33 stops spraying oil, the rotating seat 32, the rotating component 5 and the pressing component 4 move upward, and the lifting plate 61 and the tooling 14 move downward, so that the tooling 14 is placed on the rotary production line 21 and continues to move forward. Then the blocking component 73 is activated, so that the blocking wheel 72 rotates to the top of the rotary production line 21 to continue to block the next tooling 14.

[0119] Tooling 14 moves to the oil-slinging mechanism 9, gripper 943 grips the gear assembly 1 and places it into the oil-slinging tank, cover 953 and pressing member 954 move, cover 953 presses against the oil-slinging barrel 91 to seal, and pressing member 954 presses against the upper surface of gear assembly 1, shaft 92 rotates to drive gear assembly 1 to rotate, causing cooling oil to fall off under centrifugal force, thereby removing cooling oil; cover 953 and pressing member 954 move away from oil-slinging barrel 91, robot arm 24 grips gear assembly 1 and places it on a pallet, conveyor belt 25 transports the pallet to move, and the worker removes the pallet for processing, thereby completing the assembly and grinding of gear assembly 1, improving the quality and efficiency of synchronizer assembly and grinding.

[0120] Example 2, refer to Figure 10 , Figures 12-13 The difference between this embodiment and embodiment 1 is that multiple placement blocks 96 are arranged in a circumferential array around the axis of the oil-slinging barrel 91 on the upper surface of the oil-slinging seat 93, and the oil-slinging groove is opened on the multiple placement blocks 96; a scraping strip 97 is fixedly installed on the upper surface of the oil-slinging seat 93 and between two adjacent placement blocks 96. The scraping strip 97 is elastic and is arranged radially along the oil-slinging groove. The scraping strip 97 is elastic and extends upward to the top of the oil-slinging groove. The scraping strip 97 is L-shaped.

[0121] The gripping assembly 94 moves the gripping gear assembly 1 above the oil slinger, causing the scraping strips 97 to press against the lower surface and side wall of the outer ring 11. The shaft 92 rotates, driving the oil slinger 93 and multiple scraping strips 97 to rotate, causing the cooling oil on the outer ring 11 to flow onto the oil slinger 93, thereby removing the cooling oil from the outer ring 11. At this time, the rotation speed is relatively slow; this is the first rotation of the shaft 92. After the cooling oil removal is completed, the shaft 92 stops rotating, and the gripping assembly 94 releases its grip on the gear assembly 1 and moves away. The gear assembly 1 is placed on multiple scraping strips 97; the cover 953 presses against the top of the oil slinger 91 to seal it, and the pressing part 954 pushes the gear assembly 1 down, so that the outer ring 11 presses against the oil slinger groove for positioning. The shaft 92 continues to rotate, driving the oil slinger seat 93, scraping strips 97, gear assembly 1 and pressing part 954 to rotate simultaneously. The rotation speed is higher than the first rotation speed, so that the cooling oil on the gear assembly 1 and the oil slinger seat 93 falls off under centrifugal force to achieve removal.

[0122] After removal, the cover 953 and the pressing part 954 are separated from the oil slinger 91, and the gear assembly 1 can also move upward under the elastic force of the elastic scraping bar 97, which facilitates the subsequent feeding mechanism 23 to grasp and feed the material. Thus, the cooperation of the scraping bar 97, the shaft 92 and the feeding assembly 94 can further improve the removal effect of cooling oil on the gear assembly 1.

[0123] The working principle of this application embodiment is as follows:

[0124] The gripping assembly 94 and gear assembly 1 press against the scraping strip 97 for positioning. The shaft 92 rotates, causing the cooling oil on the outer ring 11 to flow to the oil slinger 93. After the cooling oil is removed, the shaft 92 stops rotating, the gripping assembly 94 releases its grip on the gear assembly 1 and moves away, and the gear assembly 1 is placed on multiple scraping strips 97. The cover 953 presses against the top of the oil slinger 91 for sealing, and the pressing part 954 pushes the gear assembly 1 down to press against the oil slinger groove for positioning. The shaft 92 continues to rotate, driving the oil slinger 93, scraping strip 97, gear assembly 1 and pressing part 954 to rotate simultaneously, so that the cooling oil on the gear assembly 1 and the oil slinger 93 falls off under centrifugal force to achieve removal.

[0125] After removal, the cover 953 and the pressing part 954 are separated from the oil slinger 91, and the gear assembly 1 can also move upward under the elastic force of the elastic scraping bar 97, which facilitates the subsequent material feeding mechanism 23 to grab and feed the material. Thus, the cooperation of the scraping bar 97, the shaft 92 and the material feeding assembly 94 can further improve the removal effect of cooling oil on the gear set and improve the quality and efficiency of synchronizer assembly and grinding.

[0126] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
