Detailed Implementation

[0025] The technical solution of the reducer end cover assembly machine of the new energy electric drive assembly line involved in this utility model will be further described in detail below with reference to the embodiments.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figures 1 to 10As shown, the new energy electric drive assembly line reducer end cover assembly machine of this embodiment includes a frame 1, a housing conveying tray 2 with a housing positioning support pin 201 and an end cover positioning pin 202, a conveying mechanism 3 that passes through the frame 1 and is used to convey the housing conveying tray 2, a lifting and positioning mechanism 4 located at the lower end of the frame 1, a lifting slide mechanism 5 located at the upper end of the frame 1, a lifting frame 6 located on the lifting slide mechanism 5, a floating mechanism 7 located on the lifting frame 6, an end cover clamping fixture 8 located on the floating mechanism 7 for clamping the end cover, and a floating positioning mechanism 9 located on the lifting frame 6 for limiting the floating mechanism 7; the housing conveying tray 2 is moved up and down by the lifting and positioning mechanism 4, and the lifting frame 6 is moved up and down by the lifting slide mechanism 5; it also includes a multi-axis robot 10, which is equipped with a gripper 11 for clamping the end cover. Using this structure, the reducer housing to be assembled is placed on the housing conveying tray 2. The housing conveying tray 2, in conjunction with the conveying mechanism 3, transports the reducer housing, thereby moving the housing conveying tray 2 with the reducer housing to the preset assembly station at the frame 1. Then, the lifting and positioning mechanism 4 drives the housing conveying tray 2 to rise and fix it in place. The multi-axis robot 10, in conjunction with the gripper 11, clamps the end cap placed at the preset position and moves the end cap to a position below the end cap clamping fixture 8. The end cap is then clamped by the end cap clamping fixture 8. After the end cap is clamped, the multi-axis robot 10 resets. Then, the lifting and sliding mechanism 3 moves the end cap to the preset position. The platform mechanism 5 drives the lifting frame 6, floating mechanism 7, end cover clamping fixture 8, and end cover to descend. After descending to a certain height, the floating positioning mechanism 9 is activated, which enables the end cover clamping fixture 8 and end cover to float, thereby achieving horizontal displacement of the end cover within a certain range. Subsequently, during the continued descent, the end cover is finally positioned by the end cover positioning pin 202 on the housing conveying tray 2 in conjunction with the floating end cover, so that the end cover and the reducer housing are accurately aligned and assembled. After assembly, all components are reset, and finally the housing conveying tray 2 with the assembled reducer continues to be moved by the conveying mechanism 3 to the next work station.

[0028] In one embodiment, such as Figure 7 , Figure 8As shown, the floating mechanism 7 includes multiple floating mounting spindles 701 mounted on the lifting frame 6, reverse-mounted flat bearings 702 mounted on the floating mounting spindles 701, and a floating frame 703 mounted on the inner ring of the reverse-mounted flat bearings 702. A mold frame 704 is detachably connected to the floating frame 703, and the end cap clamping fixture 8 is mounted on the mold frame 704. Specifically, the reverse-mounted flat bearing 702 refers to a flat bearing with its inner ring in a reversed position. Its balls are limited by the outer ring, and the outer rear balls are not in the groove of the inner ring, thus allowing the inner ring to move. That is, in the radial direction, due to the gap between the inner ring and the floating mounting spindles 701, the floating frame 703 can float freely within a certain range in the planar direction, such as 2mm, 3mm, etc. The specific floating range is determined by the selected gap between the inner ring and the floating mounting spindles 701. Specifically, the mold frame 704 can be detachably connected to the floating frame 703 in any of the existing technologies, as long as the connection and fixation of the two can be achieved. Specifically, this includes four floating mounting mandrels 701. With this structure, during the end cap assembly process, when the lifting frame 6 drives the floating mechanism 7 to descend, if there is a certain positional deviation between the end cap and the housing, the reverse-mounted plane bearing 702 allows the floating frame 703 to generate a slight displacement on the axial groove of the floating mounting mandrel 701 using its inner end, adaptively adjusting the end cap position so that the end cap can be smoothly assembled with the housing. The floating mechanism 7 effectively compensates for positional errors during assembly, avoiding damage to parts caused by rigid contact, and improving the stability and reliability of the assembly. Simultaneously, the detachable mold frame 704 facilitates tooling replacement and maintenance.

[0029] In one embodiment, such as Figure 7 , Figure 8As shown, the end cap clamping fixture 8 includes multiple sets of end cap clamping assemblies disposed on the mold frame 704; each end cap clamping assembly includes a clamping cylinder 801 disposed on the mold frame 704, and a clamping post 802 disposed on one side of the clamping cylinder 801 on the mold frame 704. A clamping hinge 803 is disposed on the clamping cylinder 801, and the output end of the clamping cylinder 801 is rotatably connected to the hinge rod of the clamping hinge rod 803. The hinge rod rotates due to the drive of the clamping cylinder 801. It also includes a positioning head 804 detachably connected to the end of the clamping post 802. Specifically, the mold frame 704 is also provided with an end cap abutment pin for limiting the end cap position. Specifically, it includes three sets of end cap clamping fixtures 8. With this structure, when the clamping cylinder 801 is working, its output end pushes the hinge rod of the clamping hinge 803 to rotate, causing the clamping hinge 803 to move and clamp the end cover between the clamping column 802 and the clamping hinge 803. The positioning head 804 can cooperate with the positioning holes and other structures on the end cover to further accurately position the end cover. The detachable positioning head 804 is easy to replace according to different end cover models, and the positioning head 804 can be installed or not. Multiple clamping components work together to provide a stable and reliable clamping force, ensuring that the end cover will not loosen during assembly. The detachable positioning head 804 design enhances the adaptability of the tooling to end covers of different specifications and improves the versatility of the equipment.

[0030] In one embodiment, such as Figure 7 , Figure 8 , Figure 9 As shown, the floating positioning mechanism 9 includes a floating positioning cylinder 901 mounted on the lifting frame 6. A floating positioning pin 902 is provided at the output end of the floating positioning cylinder 901, and a floating positioning hole 903 is provided on the floating frame 703 to cooperate with the floating positioning pin 902. Specifically, it includes two sets of floating positioning mechanisms 9. Using this structure, when the floating frame 703 needs to be positioned, the floating positioning cylinder 901 drives the floating positioning pin 902 to descend and insert into the floating positioning hole 903; when the positioning of the floating frame 703 needs to be released, the floating positioning cylinder 901 drives the floating positioning pin 902 to rise and leave the floating positioning hole 903. This method can effectively position the floating frame 703.

[0031] In one embodiment, such as Figure 4 , Figure 5As shown, the lifting and positioning mechanism 4 includes multiple primary positioning guide column assemblies 401 disposed at the lower end of the frame 1, a lifting frame 402 disposed at the upper end of the primary positioning guide column assemblies 401, a secondary positioning guide column assembly 403 disposed on the lifting frame 402, a lifting plate 404 disposed on the secondary positioning guide column assembly 403, a pallet primary lifting cylinder 405 disposed on the frame 1 for driving the lifting frame 402 to move up and down, and a housing secondary lifting cylinder 406 disposed on the lifting frame 402 for driving the lifting plate 404 to move up and down; a pallet positioning support pin 407 is disposed on the lifting frame 402, and a housing positioning support frame 408 is disposed on the lifting plate 404; a pallet positioning block 203 is disposed on the housing conveying pallet 2 for cooperating with the pallet positioning support pin 407, and a through frame hole 204 is provided on the housing conveying pallet 2 for the housing positioning support frame 408 to pass through. Specifically, the primary positioning guide post assembly 401 and the secondary positioning guide post assembly 403 have the same structure, both including a guide cylinder and a guide post body. The guide cylinder of the primary positioning guide post assembly 401 is mounted on the frame 1, and the upper end of the guide post body is mounted on the lower side of the lifting frame 402, with the guide post body penetrating the frame 1. The guide cylinder of the secondary positioning guide post assembly 403 is mounted on the lifting frame 402, and the upper end of the guide post is mounted on the lower side of the lifting plate 404, as well as penetrating the track of the secondary reaction support mechanism 13 and the frame 1. Specifically, it includes four primary positioning guide post assemblies 401 and four secondary positioning guide post assemblies 403. It includes two pallet primary lifting cylinders 405 and one housing secondary lifting cylinder 406. With this structure, when the housing conveying pallet 2 moves to the preset assembly position and stops, the first-stage lifting cylinder 405 of the pallet is activated first, driving the lifting frame 402 to rise along the first-stage positioning guide post assembly 401. The pallet positioning support pin 407 is inserted into the pallet positioning block 203 of the housing conveying pallet 2, realizing the initial positioning of the pallet. Subsequently, the second-stage lifting cylinder 406 of the housing works, pushing the lifting plate 404 to rise along the second-stage positioning guide post assembly 403. The housing positioning support frame 408 passes through the through frame hole 204 to perform secondary precise positioning and lifting of the housing. The two-stage positioning and lifting settings gradually improve the positioning accuracy of the reducer housing, ensuring that the reducer housing is in the correct position during assembly. The first-stage positioning guide post assembly 401 and the second-stage positioning guide post assembly 403 ensure the stability of the lifting process, reduce shaking, improve assembly quality, and can effectively limit the horizontal direction to prevent displacement of the pallet and reducer housing.

[0032] In one embodiment, such as Figure 1 , Figure 4 , Figure 5As shown, the frame 1 is equipped with multiple primary reaction support mechanisms 12 and multiple secondary reaction support mechanisms 13. The lifting frame 402 is equipped with a support column 16 for cooperating with the primary reaction support mechanism 12. The secondary reaction support mechanism 13 is positioned on the frame 1 below the guide column of the secondary positioning guide column assembly 403. Specifically, the primary reaction support mechanism 12 and the secondary reaction support mechanism 13 have the same structure, both including a track and a push cylinder mounted on the track. A support block is slidably connected to the track, and the output end of the push cylinder is fixedly connected to the support block and used to drive the support block to move on the track. Specifically, the track of the secondary reaction support mechanism 13 is penetrated by the guide column of the secondary positioning guide column assembly 403. Specifically, it includes four primary reaction support mechanisms 12 and four secondary reaction support mechanisms 13. With this structure, the first-stage lifting cylinder 405 of the lifting and positioning mechanism 4 first lifts the housing conveying pallet 2, then the first-stage reaction support mechanism 12 extends, and then the first-stage lifting cylinder 405 retracts so that the frame column 16 is supported on the support block of the first-stage reaction support mechanism 12; then the second-stage lifting cylinder 406 drives the reducer housing to rise, then the second-stage reaction support mechanism 13 extends, and then the second-stage lifting cylinder 406 retracts so that the lower end of the guide column of the second-stage positioning guide column assembly 403 is supported on the support block of the second-stage reaction support mechanism 13; during or after the second-stage lifting cylinder 406 drives the housing positioning support frame 408 to lift the reducer housing, positioning is achieved by the end cover positioning pin 202 provided on the housing conveying pallet 2; the first-stage reaction support mechanism 12 and the second-stage reaction support mechanism 13 can effectively disperse the force on the end cover during the descent and assembly of the reducer housing.

[0033] In one embodiment, such as Figure 6 As shown, the lifting slide mechanism 5 includes a slide frame 501, linear guide rails 502 disposed on both sides of the slide frame 501, a servo pressure cylinder 503 disposed on the frame 1, and a balance cylinder 504 disposed on the frame 1. The slide of the linear guide rail 502 is fixedly connected to the frame 1, the output end of the servo pressure cylinder 503 is fixedly connected to the lifting frame 6, and the output end of the balance cylinder 504 is disposed on the lifting frame 6. Specifically, it includes two balance cylinders 504. The servo pressure cylinder 503 is electrically driven and is electrically connected to the corresponding power supply and control equipment. With this structure, the servo pressure cylinder 503 presets a control output according to the assembly requirements, pushing the lifting frame 6 and the slide frame 501 to move up and down along the direction of the linear guide rail 502 on a fixed slider; the balance cylinder 504 plays the role of balancing the weight and motion inertia of the lifting frame 6, making the movement of the lifting frame 6 more stable and ensuring the relative positional accuracy between the end cap clamping fixture 8 and the housing.

[0034] In one embodiment, such as Figure 10As shown, the system also includes a blocking cylinder 14, the output end of which is equipped with a displacement baffle 15 for limiting the displacement of the housing conveying tray 2. With this structure, when the housing conveying tray 2 reaches the assembly station under the action of the conveying mechanism 3, the blocking cylinder 14 pushes the displacement baffle 15 to extend, preventing the housing conveying tray 2 from continuing to move forward and ensuring it accurately stops at the designated position, facilitating subsequent lifting, positioning, and assembly operations. The blocking cylinder 14 ensures the accuracy of the housing conveying tray 2's position, providing a foundation for subsequent precise assembly, avoiding the impact of tray position deviation on assembly quality, and improving the stability of the assembly process.

[0035] The conveying mechanism 3 can be any existing technology, as long as it can realize the transportation of the shell conveying pallet 2 and does not hinder the operation of the lifting and positioning mechanism 4. For details, please refer to [reference needed]. Figure 1 As shown, for example, a bracket with multiple rolling wheels is provided, and a power component that drives the rolling wheels to rotate is provided on the bracket, thereby driving the housing conveying tray 2 to move. The power source of each cylinder in this application can adopt existing technology, that is, it is connected to an air compressor through an existing compressed air delivery pipe. The air compressor includes existing components such as a power system, a compressor host, an intake system, an exhaust system, a cooling system, a lubrication system, a control system, and an air tank, thereby providing compressed air as power to the cylinder. The multi-axis robot 10 can adopt existing technology, such as: a six-axis articulated robot, which has high flexibility and range of motion and can complete complex trajectory movements in three-dimensional space; a four-axis horizontal multi-joint robot (SCARA robot), which consists of four axes, including two rotation axes, one vertical axis and one rotation axis, mainly performing high-speed movements on the horizontal plane; a five-axis robot, which adds a rotation axis to the four-axis robot, improving the attitude adjustment capability of the end effector and balancing flexibility and movement speed.

[0036] The working principle is as follows: First, the reducer housing is placed on the housing conveying tray 2. The housing conveying tray 2 moves towards the preset assembly station at the frame 1 under the drive of the conveying mechanism 3. When the housing conveying tray 2 approaches the station, the blocking cylinder 14 is activated, and the displacement baffle 15 at its output end extends to limit the continued displacement of the housing conveying tray 2, so that it stops precisely below the assembly station.

[0037] Subsequently, the lifting and positioning mechanism 4 begins to operate. The first-stage lifting cylinder 405 drives the lifting frame 402 to move upward along the first-stage positioning guide post assembly 401. The pallet positioning support pin 407 on the lifting frame 402 inserts into the pallet positioning block 203 of the housing conveying pallet 2, achieving initial positioning and lifting of the housing conveying pallet 2. Immediately afterward, the second-stage lifting cylinder 406 drives the lifting plate 404 to rise along the second-stage positioning guide post assembly 403. The housing positioning support frame 408 on the lifting plate 404 passes through the through frame hole 204 of the housing conveying pallet 2, performing secondary precise positioning and support for the reducer housing, ensuring that the housing remains stable during assembly. At the same time, the first-stage reaction force support mechanism 12 on the frame 1 cooperates with the frame column 16 of the lifting frame 402, and the second-stage reaction force support mechanism 13 corresponds to the lower part of the guide post of the second-stage positioning guide post assembly 403, jointly dispersing the forces generated during assembly and ensuring the stability of the equipment structure.

[0038] While the housing is positioned, the multi-axis robot 10 grips the end cap with its end gripper 11 and moves the end cap directly below the end cap gripping fixture 8. At this time, the gripping cylinder 801 of the end cap gripping fixture 8 is activated, and its output end drives the hinge rod of the gripping hinge frame 803 to rotate. The hinge rod cooperates with the positioning head 804 at the end of the gripping column 802 to firmly clamp the end cap. After that, the multi-axis robot 10 is reset.

[0039] Next, the lifting slide mechanism 5 is activated; the servo cylinder 503 drives the lifting frame 6 to move downward along the setting direction of the linear guide rail 502, and the balancing cylinder 504 works synchronously to balance the weight and motion inertia of the lifting frame 6, ensuring a smooth lifting process; when the lifting frame 6 descends to a certain height, the floating positioning cylinder 901 of the floating positioning mechanism 9 retracts the floating positioning pin 902, releasing the limit on the floating mechanism 7, so that the floating frame 703 can make a small horizontal displacement along the floating mounting spindle 701 under the action of the reverse-mounted plane bearing 702, and the end cover enters the floating state along with the floating frame 703.

[0040] As the lifting frame 6 continues to descend, the floating end cover gradually approaches the reducer housing. The end cover positioning pin 202 engages with the positioning hole of the end cover, and the floating mechanism 7 adaptively adjusts the horizontal position of the end cover to compensate for any possible minor positioning errors, ultimately achieving precise assembly of the end cover and the reducer housing.

[0041] After assembly, each mechanism is reset in sequence; the lifting slide mechanism 5 drives the lifting frame 6 to rise, and the floating positioning mechanism 9 repositions the floating mechanism 7; the housing secondary lifting cylinder 406 and the pallet primary lifting cylinder 405 of the lifting positioning mechanism 4, as well as the primary reaction support mechanism 12 and the secondary reaction support mechanism 13, are reset in sequence, and the housing conveying pallet 2 falls back to the conveying mechanism 3; the blocking cylinder 14 retracts the displacement baffle 15, and the housing conveying pallet 2, driven by the conveying mechanism 3, transports the assembled reducer to the next station, completing one complete assembly cycle.

[0042] Beneficial effects: This application achieves automated transportation of the reducer housing by setting up a housing conveying pallet 2 and a conveying mechanism 3, transporting it to a preset assembly station; the lifting and positioning mechanism 4 accurately positions and fixes the housing conveying pallet 2 and the reducer housing, ensuring stability during assembly; the multi-axis robot 10, in conjunction with the gripper 11, can quickly clamp the end cap and move it to the end cap clamping fixture 8, improving the end cap loading efficiency; the end cap clamping fixture 8 can reliably clamp the end cap, and the floating mechanism 7 and the floating positioning mechanism 9 allow the end cap to float horizontally within a certain range during assembly, achieving precise assembly of the end cap and the housing in conjunction with the housing positioning pin; the overall structure has a high degree of automation, effectively improving the assembly efficiency and accuracy of the reducer end cap, reducing manual labor intensity, and is suitable for large-scale production.

[0043] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge or conventional technology in the field. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
