Description

Technical Field

[0001] This utility model relates to the technical field of assembly, and in particular to an auxiliary assembly device for an electromechanical-hydraulic hybrid power output assembly. Background Technology

[0002] Electro-hydraulic hybrid power output refers to a technical mode that combines mechanical energy (driven by an internal combustion engine or electric motor), electrical energy (battery / motor system), and hydraulic energy (hydraulic pump / motor and accumulator) through coordinated control and energy coupling to form a composite power output. During assembly, a splined power output shaft needs to be press-fitted into gear grooves, bushings, or bearing inner rings. Currently, when press-fitting the power output shaft of an electro-hydraulic hybrid power output assembly, the bushing or bearing inner ring is first clamped and fixed, then lubricated with oil is applied to the surface of the power output shaft, and finally, the power output shaft is press-fitted into the bearing inner ring using a hydraulic mechanism. However, this method has the following problems: it requires manual application of lubricating oil to the surface of the power output shaft. In large-scale assembly operations, relying on manual application of lubricating oil is labor-intensive and inconvenient. Therefore, an assembly press-fitting mechanism that can automatically spray lubricating oil onto the surface of the power output shaft is needed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an auxiliary assembly device for electromechanical-hydraulic hybrid power output assembly. When assembling the drive shaft and bearing inner ring, lubricating oil can be sprayed onto the surface of the drive shaft by a spraying mechanism, eliminating the need for workers to apply lubricating oil to the surface of the drive shaft. This device is convenient to use, has low labor intensity, and is highly practical.

[0004] This utility model discloses an auxiliary assembly device for an electromechanical-hydraulic hybrid power output assembly, comprising a base plate and a bracket, with the bracket fixedly mounted on the upper part of the base plate; it also includes a three-jaw chuck A, a three-jaw chuck B, a spraying mechanism, and a pressing mechanism. The three-jaw chuck A is fixedly mounted on the upper part of the bracket, the spraying mechanism is mounted on the base plate, and the spraying mechanism has the function of spraying lubricating oil. The three-jaw chuck B is located above the three-jaw chuck A, and the three-jaw chuck B is coaxial with the three-jaw chuck A. The three-jaw chuck B is mounted on the pressing mechanism, which is used to lift and lower the three-jaw chuck B. When pressing the drive shaft into the bearing inner ring, the bearing inner ring is first passed through... The drive shaft is held and fixed by a three-jaw chuck A, and then the upper part of the drive shaft is held and fixed by a three-jaw chuck B. A spraying mechanism then sprays lubricating oil onto the press-fitted parts of the drive shaft to improve lubrication. The press-fitting mechanism then lowers the drive shaft by the three-jaw chuck B, pressing the lower part of the drive shaft into the bearing inner ring, thus completing the assembly of the drive shaft and bearing inner ring. During the assembly of the drive shaft and bearing inner ring, lubricating oil can be sprayed onto the surface of the drive shaft by the spraying mechanism, eliminating the need for manual application of lubricating oil. This method is convenient, reduces labor intensity, and is highly practical.

[0005] Preferably, the pressing mechanism includes a rotating mechanism, a lifting frame, a hydraulic cylinder, a lifting rod, and a lifting plate. The hydraulic cylinder is fixedly installed on the upper end of the lifting frame, the lifting rod is slidably installed on the lifting frame, the upper end of the lifting rod is connected to the output end of the hydraulic cylinder, the lifting plate is fixedly installed on the lower end of the lifting rod, the rotating mechanism is installed on the lower end of the lifting plate, and a three-jaw chuck B is installed on the rotating mechanism. The rotating mechanism is used to rotate the three-jaw chuck B. The lifting frame is fixedly installed on the support frame of the workshop. When pressing the drive shaft into the inner ring of the bearing, the hydraulic cylinder is opened, and the hydraulic cylinder lowers the lifting plate through the lifting rod. The lifting plate drives the rotating mechanism and the three-jaw chuck B to lower, and the three-jaw chuck B drives the drive shaft to lower. During the descent, the drive shaft is pressed into the inner ring of the bearing, completing the assembly between the drive shaft and the inner ring of the bearing, which facilitates the pressing of the drive shaft.

[0006] Preferably, the rotating mechanism includes a fixed frame, a rotating shaft, bevel gear A, bevel gear B, a drive shaft, and a motor. The fixed frame is fixedly installed at the lower end of the lifting plate. The rotating shaft is rotatably installed on the fixed frame and the lifting plate. Bevel gear A is fixedly fitted onto the surface of the rotating shaft. Bevel gear A meshes with bevel gear B. The drive shaft is fixedly connected to bevel gear B. The drive shaft is rotatably installed on the fixed frame. The input end of the drive shaft is connected to the motor, and the motor is fixedly installed on the fixed frame. When spraying lubricating oil onto the surface of the press-fitting part of the drive shaft, the motor is turned on. The motor drives bevel gear B to rotate bevel gear A through the drive shaft. Bevel gear A drives the rotating shaft and the three-jaw chuck B to rotate. The three-jaw chuck B drives the drive shaft to rotate. During the rotation of the drive shaft, the spraying mechanism can evenly spray lubricating oil onto the surface of the drive shaft. This facilitates the spraying of lubricating oil onto the surface of the drive shaft.

[0007] Preferably, the spraying mechanism includes a moving mechanism, a lubricating oil tank, a delivery pump, a delivery hose, and a nozzle. The lubricating oil tank is fixedly mounted on the base plate, and the delivery pump is fixedly mounted on the base plate. The input end of the delivery pump is connected to the lubricating oil tank, and the output end of the delivery pump is connected to the nozzle through the delivery hose. The nozzle is mounted on the moving mechanism, which is used to move the nozzle. When spraying lubricating oil onto the surface of the press-fitted part of the drive shaft through the nozzle, the moving mechanism moves the nozzle to a suitable position for spraying lubricating oil onto the surface of the drive shaft. Then, the delivery pump is turned on, so that the lubricating oil in the lubricating oil tank is sprayed onto the surface of the drive shaft sequentially through the delivery pump, the delivery hose, and the nozzle. At the same time, the drive shaft is rotated by the rotating mechanism, and the drive shaft is evenly sprayed by the nozzle during the rotation.

[0008] Preferably, the moving mechanism includes a lifting mechanism, a hydraulic cylinder, and a push rod. The hydraulic cylinder is mounted on the lifting mechanism, which is used to raise and lower the hydraulic cylinder. The push rod is mounted on the output end of the hydraulic cylinder, and the nozzle is fixedly mounted on the right end of the push rod. When spraying lubricating oil onto the surface of the drive shaft through the nozzle, the hydraulic cylinder is opened, and the hydraulic cylinder drives the push rod to move to the right, thereby bringing the nozzle closer to the drive shaft until the nozzle moves to a suitable position for spraying lubricating oil onto the surface of the drive shaft. Then, lubricating oil is sprayed onto the surface of the drive shaft through the nozzle. Since the nozzle can move in the left and right directions, its position in the left and right directions can be directly adjusted according to the drive shaft, making it suitable for drive shafts of different diameters. It is convenient to use and has low limitations.

[0009] Preferably, the lifting mechanism includes a base, an electric slide rail, and a sliding plate. The electric slide rail is fixedly mounted on the base plate, and the sliding plate is mounted on the electric slide rail. The electric slide rail is used to lift the sliding plate, and the hydraulic cylinder is fixedly mounted on the sliding plate. When adjusting the height of the nozzle, the electric slide rail is opened, causing the sliding plate to lift. The sliding plate drives the hydraulic cylinder to lift, which in turn causes the push rod to lift the nozzle. Since the height of the nozzle is adjustable, lubricating oil can be sprayed at any height of the drive shaft according to the needs of the operator, improving convenience.

[0010] Preferably, the lubricating oil storage tank is equipped with a level gauge; this facilitates the monitoring of the lubricating oil level in the storage tank.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: when assembling the drive shaft and the inner ring of the bearing, lubricating oil can be sprayed onto the surface of the drive shaft by a spraying mechanism, eliminating the need for workers to apply lubricating oil to the surface of the drive shaft. This makes it convenient to use, reduces labor intensity, and is highly practical. Attached Figure Description

The three-jaw chuck B4 is installed on the pressing mechanism, which is used to lift and lower the three-jaw chuck B4. When pressing the drive shaft 25 into the bearing inner ring 24, the bearing inner ring 24 is first passed through the three-jaw chuck. A3 clamps and fixes the drive shaft 25, then the upper part is clamped and fixed by the three-jaw chuck B4. Next, a spraying mechanism sprays lubricating oil onto the press-fitted parts of the drive shaft 25 to improve the lubrication effect on the surface of the drive shaft 25. Then, the press-fitting mechanism causes the three-jaw chuck B4 to lower the drive shaft 25, pressing the lower part of the drive shaft 25 into the bearing inner ring 24, thus completing the assembly between the drive shaft 25 and the bearing inner ring 24. During the assembly of the drive shaft 25 and the bearing inner ring 24, lubricating oil can be sprayed onto the surface of the drive shaft 25 through the spraying mechanism, eliminating the need for manual application of lubricating oil. This method is convenient, reduces labor intensity, and is highly practical.

[0020] like Figure 1 and Figure 2The pressing mechanism includes a rotating mechanism, a lifting frame 5, a hydraulic cylinder 6, a lifting rod 7, and a lifting plate 8. The hydraulic cylinder 6 is fixedly installed on the upper end of the lifting frame 5. The lifting rod 7 is slidably installed on the lifting frame 5, and the upper end of the lifting rod 7 is connected to the output end of the hydraulic cylinder 6.

The three-jaw chuck B4 is installed on the rotating mechanism, which is used to rotate the three-jaw chuck B4. The lifting frame 5 is fixedly installed on the support frame of the workshop. When pressing the drive shaft 25 into the inner ring 24 of the bearing, the hydraulic cylinder 6 is opened. The hydraulic cylinder 6 lowers the lifting plate 8 through the lifting rod 7. The lifting plate 8 drives the rotating mechanism and the three-jaw chuck B4 to lower. The three-jaw chuck B4 drives the drive shaft 25 to lower. During the descent, the drive shaft 25 is pressed into the inner ring 24 of the bearing, completing the assembly between the drive shaft 25 and the inner ring 24 of the bearing, which facilitates the pressing of the drive shaft 25.

[0021] like Figure 5 The rotating mechanism includes a fixed frame 9, a rotating shaft 10, bevel gear A11, bevel gear B12, a drive shaft 13, and a motor 14. The fixed frame 9 is fixedly installed on the lower end of the lifting plate 8. The rotating shaft 10 is rotatably installed on the fixed frame 9 and the lifting plate 8. The bevel gear A11 is fixedly fitted onto the surface of the rotating shaft 10, and the bevel gear A11 meshes with the bevel gear B12. The drive shaft 13 is fixedly connected to the bevel gear B12 and is rotatably installed on the fixed frame 9. The input end of the drive shaft 13 is connected to the motor 14. The motor 14 is fixedly mounted on the fixed frame 9. When spraying lubricating oil onto the surface of the press-fitting part of the drive shaft 25, the motor 14 is turned on. The motor 14 drives the bevel gear B12 to rotate the bevel gear A11 through the drive shaft 13. The bevel gear A11 drives the rotating shaft 10 and the three-jaw chuck B4 to rotate. The three-jaw chuck B4 drives the drive shaft 25 to rotate. During the rotation, the drive shaft 25 is evenly sprayed with lubricating oil by the spraying mechanism. This facilitates the spraying of lubricating oil onto the surface of the drive shaft 25.

[0022] like Figure 1 and Figure 3The spraying mechanism includes a moving mechanism, a lubricating oil tank 15, a delivery pump 16, a delivery hose 17, and a nozzle 18. The lubricating oil tank 15 is fixedly installed on the base plate 1, and the delivery pump 16 is fixedly installed on the base plate 1. The input end of the delivery pump 16 is connected to the lubricating oil tank 15, and the output end of the delivery pump 16 is connected to the nozzle 18 through the delivery hose 17. The nozzle 18 is installed on the moving mechanism, which is used to move the nozzle 18. When spraying lubricating oil onto the surface of the press-fitting part of the drive shaft 25 through the nozzle 18, the moving mechanism moves the nozzle 18 to a suitable position for spraying lubricating oil onto the surface of the drive shaft 25. Then, the delivery pump 16 is turned on, so that the lubricating oil in the lubricating oil tank 15 is sprayed onto the surface of the drive shaft 25 sequentially through the delivery pump 16, the delivery hose 17, and the nozzle 18. At the same time, the drive shaft 25 is rotated by the rotating mechanism, and the drive shaft 25 is evenly sprayed by the nozzle 18 during the rotation.

The push rod 20 is mounted on the output end of the hydraulic cylinder 19, and the nozzle 18 is fixedly mounted on the right end of the push rod 20. When spraying lubricating oil onto the surface of the drive shaft 25 through the nozzle 18, the hydraulic cylinder 19 is opened, and the hydraulic cylinder 19 drives the push rod 20 to move to the right, thereby bringing the nozzle 18 closer to the drive shaft 25 until the nozzle 18 moves to a suitable position for spraying lubricating oil onto the surface of the drive shaft 25. After that, lubricating oil is sprayed onto the surface of the drive shaft 25 through the nozzle 18. Since the nozzle 18 can move in the left and right directions, its position in the left and right directions can be directly adjusted according to the drive shaft 25. It can be applied to drive shafts 25 of different diameters, is convenient to use, and has low limitations.

[0024] like Figure 3 The lifting mechanism includes a base 21, an electric slide rail 22, and a sliding plate 23. The electric slide rail 22 is fixedly installed on the base plate 1 via the base 21, and the sliding plate 23 is installed on the electric slide rail 22. The electric slide rail 22 is used to lift the sliding plate 23. The hydraulic cylinder 19 is fixedly installed on the sliding plate 23. When adjusting the height of the nozzle 18, the electric slide rail 22 is opened, which causes the sliding plate 23 to lift. The sliding plate 23 drives the hydraulic cylinder 19 to lift, which in turn causes the push rod 20 to lift the nozzle 18. Since the height of the nozzle 18 can be adjusted, lubricating oil can be sprayed at any height of the drive shaft 25 according to the needs of the staff, which improves convenience. Example

[0025] Based on Example 1, a level gauge is installed on the lubricating oil storage tank 15; the above-mentioned installation facilitates the monitoring of the lubricating oil level in the lubricating oil storage tank 15.
