[0068] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0069] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0070] It should be noted that the directional words such as "up, down, left, right, front, back" below are defined based on the drawings in the specification.

[0071] The core of the utility model is to provide a transmission shaft assembly device, which can detect whether a seal is missing, complete the oiling of the transmission shaft ball cage and the installation and riveting of the dust cover, and realize the high-precision assembly process of the transmission shaft.

[0072] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A transmission shaft assembly device includes a frame 1, a first pushing mechanism 2, a second pushing mechanism 4, a positioning mechanism 6, a photoelectric sensor 7, a riveting mechanism 8, an oiling mechanism 9, a clamping mechanism 10 and a control device 11.

[0073] Specifically, the first pushing mechanism 2, the second pushing mechanism 4, the positioning mechanism 6, the photoelectric sensor 7, the riveting mechanism 8, the oil injection mechanism 9 and the clamping mechanism 10 are all connected to the control device 11, and the operating states of the first pushing mechanism 2, the second pushing mechanism 4, the positioning mechanism 6, the photoelectric sensor 7, the riveting mechanism 8, the oil injection mechanism 9 and the clamping mechanism 10 are controlled by the control device 11 to ensure an efficient, orderly and fully automated process for assembling the drive shaft.

[0074] The first pushing mechanism 2 is provided at the first end of the frame 1, and is used to drive the first transmission shaft 01 to rotate circumferentially and move toward the second end of the frame 1. The first pushing mechanism 2 is controlled by the control device 11 to drive the first transmission shaft 01 to move toward the second end of the frame 1. The second pushing mechanism 4 is provided at the second end of the frame 1, and is used to drive the second transmission shaft 02 to rotate circumferentially and move toward the first end of the frame 1. The second pushing mechanism 4 is controlled by the control device 11 to drive the second transmission shaft 02 to move toward the first end of the frame 1. In other words, through the operation of the first pushing mechanism 2 and the second pushing mechanism 4, the first transmission shaft 01 and the second transmission shaft 02 are moved in a direction close to each other, providing a basis for the operation of the next process.

[0075] A gap is left between the first pushing mechanism 2 and the second pushing mechanism 4, leaving enough operating space for the installation and operation of other mechanisms to avoid interference. The positioning mechanism 6 can be raised and lowered on the frame 1 and located in the gap. The positioning mechanism 6 is provided with a photoelectric sensor 7 for detecting the seal to avoid the occurrence of missing seals. The oiling mechanism 9 is movably arranged obliquely above the positioning mechanism 6. The control device 11 controls the oiling mechanism 9 to move to the center position of the first transmission shaft 01, controls the first pushing mechanism 2 and the second pushing mechanism 4 to operate, so that the first transmission shaft 01 and the second transmission shaft 02 move toward each other, so that the first transmission shaft 01 is docked with the oiling mechanism 9. After the docking is completed, the oiling mechanism 9 is controlled to oil the first transmission shaft 01. After the oiling is completed, the first pushing mechanism 2, the second pushing mechanism 4 and the oiling mechanism 9 are controlled to return to the initial position to provide space for the next process.

[0076] A movable clamping mechanism 10 is provided below the oil injection mechanism 9. When the oil injection mechanism 9 returns to the initial position, the control device 11 controls the clamping mechanism 10 to move to the position of the second transmission shaft 02 and clamps the second transmission shaft 02. The first pushing mechanism 2 and the second pushing mechanism 4 are controlled to operate, and the splines on the second transmission shaft 02 are pressed into the first transmission shaft 01 to complete the press-fitting of the splines. The riveting mechanism 8 is provided at the output end of the first pushing mechanism 2 and is used to rivet the dust cover to the first transmission shaft 01. After the spline press-fitting is completed, the positioning mechanism 6 and the riveting mechanism 8 are controlled to operate so that the dust cover can be smoothly pressed into the ball cage of the first transmission shaft 01, thereby completing the assembly of the first transmission shaft 01.

[0077] When the transmission shaft needs to be assembled, first install the first transmission shaft on the first pushing mechanism 3, and then install the second transmission shaft on the second simultaneous mechanism 5. The photoelectric sensor 7 on the positioning mechanism 6 detects whether there is a seal inside the ball cage of the first transmission shaft. If not, an alarm is issued. If yes, the control device 11 controls the oil injection mechanism 9 to operate with the first pushing mechanism 2 and the second pushing mechanism 4 to oil the ball cage of the first transmission shaft. After completion, the first pushing mechanism 2, the second pushing mechanism 4 and the oil injection mechanism 9 are controlled to return to the initial position. Then the clamping mechanism 10 is controlled to cooperate with the first pushing mechanism 2 and the first rotating mechanism 3 to press the spline on the second transmission shaft 02 into the first transmission shaft. After completion, the positioning mechanism 6, the riveting mechanism 8 and the second pushing mechanism 4 are controlled to cooperate to press the dust cover into the ball cage of the first transmission shaft to complete the assembly of the first transmission shaft. The transmission shaft assembled through the above installation process has higher precision.

[0078] The transmission shaft assembly equipment arranged in the above manner can detect whether the seal is missing, realize automatic oiling of the transmission shaft ball cage and automatic installation and riveting of the dust cover, so as to improve the installation accuracy of the transmission shaft.

[0079] Please refer to Figure 2 The first pushing mechanism 2 includes a first rotating mechanism 3 for driving the first transmission shaft 01 to rotate. The first rotating mechanism 3 is connected to the servo motor 23, and the servo motor 23 is connected to the control device 11. It also includes a first driving device 21 and a rodless cylinder 22 connected to the control device 11. The output end of the first driving device 21 is connected to a first flat plate structure that is movable along the first guide rail. The first guide rail is arranged at the first end of the frame 1. A limiting plate 12 for installing the first rotating mechanism 3 is arranged on the first flat plate structure. The rodless cylinder 22 is arranged below the first flat plate structure. The rodless cylinder 22 is used to drive the first rotating mechanism 3 to move along the first flat plate structure.

[0080] The first guide rail is arranged at the first end of the frame 1, and a limit plate 12 for installing the first rotating mechanism 3 is arranged on the first flat plate structure. The rodless cylinder 22 is arranged below the first flat plate structure. The rodless cylinder 22 is used to drive the first rotating mechanism 3 to move axially along the first transmission shaft. That is to say, a sliding structure is provided at the bottom of the limit plate 12, and the sliding structure is arranged on the first plane structure. The sliding structure includes a slide rail and a slider. The slide rail is arranged on the first plane structure, and the slider is arranged at the bottom of the limit plate 12. The control device 11 controls the operation of the rodless cylinder 22 to drive the limit plate 12 and the first rotating mechanism 3 on the limit plate 12 to move. The first rotating mechanism 3 is connected to the servo motor 23, and the servo motor 23 is controlled to operate by the control device 11 to drive the first rotating mechanism 3 to rotate.

[0081] It should be noted that when in use, the first transmission shaft is first placed on the station of the first pushing mechanism 2, and the first rotating mechanism 3 is manually dragged so that the pin of the first rotating mechanism 3 is inserted into the first transmission shaft to fix the position of the first rotating mechanism 3 and the first transmission shaft.

[0082] In this embodiment, the first driving device 21 includes a motor and an electric cylinder. The motor is controlled by the control device 11 to provide power to the electric cylinder, and the electric cylinder drives the first flat plate structure to move along the first guide rail, that is, to move left and right, and the components installed on the first flat plate structure will also move accordingly. The servo motor 23 is controlled by the control device 11 to drive the first rotating mechanism 3 to rotate, and the first rotating mechanism 3 then drives the first transmission shaft to rotate together. A rodless cylinder 22 is arranged under the first flat plate structure, which can drive the servo motor 23 and the first rotating mechanism 3 to move left and right synchronously. When the first transmission shaft needs to be engaged, the rodless cylinder 22 will drive the servo motor 23 and the first rotating mechanism 3 to move to the right to support the first transmission shaft.

[0083] The limit plate 12 is locked on the slide rail with a T-nut to prevent the servo motor 23 and the first rotating mechanism 3 from being unstable in one direction during operation. A limiter is also provided on the limit plate 12 to limit the first transmission shaft. When the first transmission shaft is press-fitted, the limiter can serve as a limit support to prevent the first transmission shaft from moving to the left.

[0084] In the above situation, the second pushing mechanism 4 includes a second rotating mechanism 4 for driving the second transmission shaft 02 to rotate and a second driving device 41 connected to the control device 11. The operating state of the second driving device 41 is controlled by the control device 11. The output end of the second driving device 41 is connected to a second flat plate structure that is movable along the second guide rail. The second driving device 41 operates to drive the second flat plate structure to move along the second guide rail, and at the same time drives the various components on the second flat plate structure to move simultaneously. The second guide rail is arranged at the second end of the frame 1, and a limiting plate 12 for installing the second rotating mechanism 5 is arranged on the second flat plate structure. The second rotating mechanism 5 includes a first cylinder 51 for driving the second transmission shaft to rotate and a limiting block 52 for supporting and installing the second transmission shaft. The first cylinder 51 is connected to the control device 11, and the output end of the first cylinder 51 is connected to the positioning structure. The positioning structure moves radially telescopically along the second transmission shaft and is engaged or disengaged with the groove arranged on the second transmission shaft.

[0085] It is understandable that when in use, the second transmission shaft is first placed on the station of the second pushing mechanism 4, and the second transmission shaft is pushed toward the second rotating mechanism 5, so that the pin of the second rotating mechanism 5 is inserted into the second transmission shaft to fix the position of the second rotating mechanism 5 and the second transmission shaft. In this embodiment, the first cylinder 51 is arranged above the second transmission shaft, and the operation of the first cylinder 51 is controlled by the control device 11. When the output end of the first cylinder 51 extends, the positioning structure is driven to move downward and is stuck with the groove on the second transmission shaft to prevent the second transmission shaft from rotating. When the output end of the first cylinder 51 contracts, the positioning structure is driven to move upward to separate the positioning structure from the groove on the second transmission shaft, so that the second transmission shaft can rotate.

[0086] The first driving device 41 includes a motor and an electric cylinder. The control device 11 controls the motor to provide power to the electric cylinder, and the electric cylinder drives the second flat plate structure to move along the second guide rail, that is, to move left and right, and the components installed on the second flat plate structure will also move accordingly.

[0087] The overall design of the second pushing mechanism 4 is not much different from the first pushing mechanism 2, but the servo motor 23 and the first rotating mechanism 3 are not provided. A second rotating mechanism 5 is designed. The second rotating mechanism 5 has a first cylinder 51, a limit block 52 and a positioning structure. A groove is provided on the second transmission shaft. The first cylinder 51 pushes the positioning structure downward to jam the second transmission shaft to prevent the second transmission shaft from rotating. When the first cylinder 51 is raised, the second transmission shaft can rotate, and the limit block 52 plays a supporting role.

[0088] Please refer to Figure 2 and Figure 3 Two connecting rods 13 arranged in parallel are provided on the limiting plate 12. The connecting rod 13 penetrates the limiting plate 12 through a petal-type fixer. The connecting rod 13 is located on both sides of the first rotating mechanism 3 and the second rotating mechanism 5.

[0089] It should be noted that connecting rods 13 are added on both sides of the limiting plate 12, and the connecting rods 13 pass through the limiting plate 12 using a petal-shaped fixture, and the two sides of the petal-shaped fixture are tightened using the threads of the nut.

[0090] In the above embodiment, the first flat plate structure and the second flat plate structure both include a movable base plate 14 and mounting seats 15 arranged at both ends of the movable base plate 14. The bottom of the movable base plate 14 is provided with a slider that slides in cooperation with the first guide rail and the second guide rail. The bottom of the movable base plate 14 is connected to a triangular plate 16, and the triangular plate 16 is connected to the corresponding first drive device 21 and the second drive device 41.

[0091] It can be understood that the control device 11 controls the motor to provide power to the electric cylinder, and the electric cylinder drives the set plate 16 and the movable plate connected to the set plate 16 to move left and right along the corresponding first guide rail and second guide rail, and the components installed on the movable plate will also move accordingly.

[0092] Please refer to Figure 4 and Figure 5 The positioning mechanism 6 includes a second cylinder 61, a fixing plate 62, a mounting plate 63, a top column 64, a third cylinder 65 and a positioning frame 66. The second cylinder 61 and the third cylinder 65 are both connected to the control device 11, and the operating states of the second cylinder 61 and the third cylinder 65 are controlled by the control device 11. The second cylinder 61 is a vertical structure, and the second cylinder 61 is fixed to the frame 1 through the fixing plate 62. The output end of the second cylinder 61 is connected to the mounting plate 63, and the output end of the second cylinder 61 is telescopically movable along the height direction of the frame 1. The top column 64 is arranged on the mounting seat 15 and is used to support the mounting plate 63. The third cylinder 65 is a horizontal structure and is arranged on the mounting plate 63. The output end of the third cylinder 65 is connected to the positioning frame 66.

[0093] It should be noted that the second cylinder 61 is fixed to the fixing plate 62 by a connecting piece, and the third cylinder 65 is fixed to the mounting plate 63. When the output end of the second cylinder 61 is controlled to rise by the control device 11, the mounting plate 63 can be supported to rise. When the mounting plate 63 reaches the preset position, the top column 64 on the mounting seat 15 moves to the left under the drive of the second driving device 41 until the top column 64 abuts against the end surface of the mounting plate 63, and the third cylinder 65 is further controlled to operate so that the output end of the third cylinder 65 extends out to open the positioning frame 66, and further the positioning frame 66 is driven by the mounting plate 63 to move to a position where it is engaged with the dust cover, and the third cylinder 65 is controlled to contract and stop after the dust cover is completely clamped. The positioning frame 66 can provide support for the dust cover when it is installed in the ball cage.

[0094] Among them, there are two third cylinders 65, which are arranged in parallel on the mounting plate 63, and the output ends of the two third cylinders 65 are telescoped outward, and the output end of the third cylinder 65 is connected to the positioning frame 66 through a connecting plate and a connecting rod to drive the opening and closing of the positioning frame 66 at the output end of the third cylinder 65. The groove on the positioning frame 66 for clamping the dust cover is set to a shape that matches the dust cover to achieve the clamping of the dust cover. In this embodiment, the third cylinder 65 and the positioning frame 66 are arranged in this way, but in actual application, there is no limitation on this, as long as the above technical effects can be achieved.

[0095] Please refer to Figure 6 and Figure 7 The oil injection mechanism 9 includes a fourth cylinder 91, a first bracket 92, an oil injection structure 93 and a spring 94. The fourth cylinder 91 is arranged on the frame 1 and connected to the control device 11. The output end of the fourth cylinder 91 moves obliquely downward. The first bracket 92 is connected to the output end of the fourth cylinder 91. The end of the first bracket 92 is provided with an oil injection structure 93. The outer peripheral sleeve of the oil injection structure 93 is provided with a spring 94. The oil injection structure 93 is connected to the oil injection equipment through an oil pipe.

[0096] It can be understood that when the first transmission shaft needs to be oiled, the control device 11 controls the fourth cylinder 91 to operate so that the output end of the fourth cylinder 91 extends obliquely downward to drive the first bracket 92 to move synchronously. When the first bracket 92 reaches the preset position, that is, the oil injection structure 93 on the first bracket 92 is aligned with the center of the first transmission shaft, the second drive device 41 is controlled to operate to drive the second transmission shaft to move to the left, so that the second transmission shaft pushes the oil injection structure 93 to move toward the hole of the first transmission shaft. When the oil injection structure 93 reaches contact with the inside of the hole, the first transmission shaft is oiled through the cooperation of the oil injection equipment and the oil pipe. After the set amount of oil is injected, the second transmission shaft is driven by the second drive device 41 to move backward. Under the rebound force of the spring 94, the oil injection structure 93 is also pulled out of the hole of the first transmission shaft and returns to its original position.

[0097] In this embodiment, the oil injection structure 93 is provided with an oil inlet hole and an oil outlet hole, and the oil inlet hole is connected to the oil injection device through an oil pipe, so that the oil of the oil injection device enters the oil injection structure 93 through the oil pipe from the oil inlet hole, and flows out through the oil outlet hole of the oil injection structure 93 to reach the first transmission shaft. In other words, the oil injection structure 93 is equivalent to a joint.

[0098] On the basis of the above embodiment, the clamping mechanism 10 includes a fifth cylinder 101, a second bracket 102, a sixth cylinder 103 and a clamp 104. The fifth cylinder 101 and the sixth cylinder 103 are both connected to the control device 11, and the operating status of the fifth cylinder 101 and the sixth cylinder 103 are controlled by the control device 11. The fifth cylinder 101 is arranged on the frame 1, and the output end of the fifth cylinder 101 moves obliquely upward. The second bracket 102 is connected to the output end of the fifth cylinder 101. The end of the second bracket 102 is provided with a sixth cylinder 103, and the output end of the sixth cylinder 103 is connected to the clamp 104. The sixth cylinder 103 is used to adjust the opening degree of the clamp 104.

[0099] It should be noted that when the clamping mechanism 10 is used, a retaining spring is first placed on the second transmission shaft, and the fifth cylinder 101 is controlled to operate by the control device 11. The second bracket 102 pushes the clamp 104 to the position of the second transmission shaft under the action of the fifth cylinder 101, and the sixth cylinder 103 is controlled to operate so that the clamp 104 is first opened. When the clamp 104 corresponds to the retaining spring, the clamp 104 is controlled to close to clamp the retaining spring. The first transmission shaft is driven to move to the right by the first driving device 21, and the rodless cylinder 22 drives the first rotating mechanism 3 to rotate while rolling the teeth to the right. A judgment device is set to judge whether the first transmission shaft has completed the tooth rolling. When the torque reaches the preset value, it means that the teeth have been rolled in. At this time, the second driving device 41 will drive the second transmission shaft to move to the left. When the retaining spring is completely entered into the first transmission shaft, it stops pushing. At this time, the control device 11 successively controls the sixth cylinder 103 and the fifth cylinder 101 to operate so that the clamp 104 releases the retaining spring and the second bracket 102 is reset to the original position.

[0100] Furthermore, a press-fitting system is provided below the first pushing structure, which can judge the tightness of the teeth while pressing. The teeth are qualified only when the tightness reaches a certain range. When the retaining spring on the second transmission shaft is pressed into the groove in the first transmission shaft, the retaining spring will burst and jam the retaining spring in the groove. At this time, the press-fitting action continues until it cannot be pushed up. A judgment is made on the force that cannot be pushed up, that is, whether it exceeds the normal value of 1.5T. If it exceeds and is 3-5T, it is qualified, otherwise it is unqualified. In this example, the judged value is the above value, but in actual application, there is no limitation on this, as long as the above technical effect can be achieved.

[0101] Please refer to Figure 8 The riveting mechanism 8 includes a seventh cylinder 81 and a press-fitting structure. The seventh cylinder 81 is arranged on both sides of the mounting seat 15 and is connected to the control device 11. The seventh cylinder 81 is a horizontal structure. The press-fitting structure is connected to the output end of the seventh cylinder 81. The press-fitting structure is used to press the dust cover onto the first transmission shaft.

[0102] It is understandable that when the servo motor 23 drives the first transmission shaft to rotate, the control device 11 controls the seventh cylinder 81 to drive the press-fitting structure to move toward the dust cover until the dust cover is press-fitted into the ball cage of the first transmission shaft.

[0103] In the above embodiment, the pressing structure includes a connecting frame 82, a U-shaped mounting frame 83 and a pressing block 84. The connecting frame 82 is connected to the output end of the seventh cylinder 81. A U-shaped mounting frame 83 is provided at the end of the connecting frame 82. The opening of the U-shaped mounting frame 83 is set toward the first transmission shaft. There are two pressing blocks 84. The two pressing blocks 84 are arranged in parallel on the U-shaped mounting frame 83. The pressing block 84 is a cylindrical structure, and a boss is provided on the outer periphery of the pressing block 84.

[0104] It should be noted that there are two seventh cylinders 81 located on both sides of the dust cover. When the dust cover needs to be pressed into the first transmission shaft, the control device 11 controls the seventh cylinder 81 to drive the connecting frame 82 to move in the direction close to the dust cover, and at the same time makes the U-shaped mounting frame 83 and the pressure block 84 fixed therein move toward the dust cover synchronously, and uses the boss parts on the two pressure blocks 84 on one side to rivet the dust cover on the first transmission shaft.

[0105] In summary, the transmission shaft assembly equipment provided by the utility model is as follows: the first step is to place the first transmission shaft on the station of the first pushing mechanism 2, and then manually drag the first rotating mechanism 3 to insert it into the first transmission shaft and fix it through the pin; the second step is to place the second transmission shaft on the station of the second pushing mechanism 4, and push the second transmission shaft to the pin on the second rotating mechanism 5 to fix it; the third step is to use the photoelectric sensor 7 on the positioning mechanism 6 to detect whether the oil seal inside the ball cage on the first transmission shaft is missing, and if it is not placed, an alarm will be prompted; the fourth step is to perform oil filling, and use the fourth cylinder 91 Push the entire set of oil injection mechanism 9 to the center of the first transmission shaft, and then the electric cylinder under the first pushing mechanism 2 will move the entire left mechanism to the right, and it will stop moving until the oil injection structure 93 enters the hole of the first transmission shaft; in the fifth step, the second pushing mechanism 4 is moved to the left as a whole by the electric cylinder, and continues to be pushed to the left after contacting the oil injection structure 93. After it is inserted to the bottom, it will start the oil injection operation into the ball cage. After completion, the second pushing mechanism 4 will withdraw backwards, and the oil injection mechanism 9 structure will withdraw from the first transmission shaft under the rebound force of the spring 94. After the oil injection is completed, all mechanisms are reset to their original positions.

[0106] The sixth step starts to align the teeth. A retaining spring is placed on the second transmission shaft. Under the action of the fifth cylinder 101, the second bracket 102 pushes the clamp 104 to the position of the second transmission shaft to clamp the retaining spring. The first transmission shaft on the left is moved to the right through the cylinder. When the first transmission shaft is about to contact the second transmission shaft, the rodless cylinder 22 drives the first rotating mechanism 3 to rotate and rub the teeth to the right. When the torque of the tooth rubbing reaches the preset value, it means that the tooth rubbing has been completed. At this time, the first transmission shaft is controlled to stop rotating, and the second pushing mechanism 4 will move the second transmission shaft to the left. When the retaining spring completely enters the first transmission shaft on the left, it stops pushing, and then the clamping mechanism 10 is controlled to release and reset to the original position.

[0107] Step 7: After the spline is pressed into the first transmission shaft, the second push mechanism 4 on the right side moves to the left as a whole and moves to the top of the positioning mechanism 6. The positioning mechanism 6 will move upward under the action of the second cylinder 61 to a position in the center of the first transmission shaft. The riveting mechanism 8 and other related mechanisms will move to the right to push the first transmission shaft into the positioning frame 66. The second push mechanism 4 moves to the left to support the top column 64 on the mounting plate 63 of the positioning mechanism 6 to prevent deformation. The riveting mechanism 8 and other related parts continue to move to the right until the dust cover is pressed into the ball cage. Then the riveting mechanism 8 moves to the center of the first transmission shaft, the first rotating mechanism 3 is ready to rotate, and the first cylinder 51 of the second rotating mechanism 5 is released, so that the second transmission shaft can also rotate synchronously. The riveting mechanism 8 continues to move to the center of the first transmission shaft for riveting until the pressing block 84 is stuck in the groove of the ball cage and the edge of the dust cover is riveted into the groove; Step 8: Control all mechanisms to return to a safe position, the first transmission shaft is pressed and can be taken out.

[0108] This equipment is mainly used for the assembly of transmission shafts, detection of missing seals, oiling of ball cages, installation and riveting of dust covers, press-fitting and monitoring of star wheel spline teeth and shaft spline teeth in ball cages. It has convenient detection, high assembly accuracy and low scrap rate.
