Description

Technical Field

[0001] This invention belongs to the field of transmission oil draining technology, and relates to a transmission oil draining method and apparatus. Background Technology

[0002] Currently, the typical workflow after transmission assembly is as follows: transmission off-line inspection – oil filling and test run – oil draining – cleaning and painting – packaging and warehousing. Due to the oil adhering to the transmission housing walls and gear teeth, it is difficult to completely drain the test oil within a short time after the test run. Each transmission contains approximately 800ml of residual test oil, requiring a two-hour settling period for complete drainage. With an assembly line cycle of 120 seconds per unit, draining the oil after approximately two hours necessitates placing 60 transmissions on the floor, occupying a large area. Furthermore, the transmissions need to be re-mounted and painted two hours later, requiring two hand-handling processes. This leads to problems such as a fast production line cycle, difficulty in completely draining the test oil, and high labor intensity from repeated transmission assembly. How to completely drain the test oil after the test run has become a key factor affecting the after-sales quality of the transmission and increasing test run costs, urgently requiring a solution and device. Summary of the Invention

[0003] To address the problems existing in the prior art, this invention provides a method and apparatus for draining transmission oil, which solves the problems of difficulty in completely draining residual test oil during operation when the transmission is not grounded, and the high labor intensity of repeated transmission line operation, thereby improving the after-sales service quality of the transmission.

[0004] This invention is achieved through the following technical solution:

[0005] A transmission oil draining device includes an oil receiving device and a downhill track.

[0006] The oil receiving device is placed directly below the downhill track. The oil receiving device includes an oil discharge ramp and an oil collection tank. A gearbox is suspended on the downhill track. The oil collection tank is located at the end of the oil discharge ramp.

[0007] Preferably, the oil receiving device further includes a preparation platform, which is located at the front end of the oil discharge ramp.

[0008] Preferably, the centerline of the drain ramp, the centerline of the drain hole of the transmission, and the centerline of the downhill track are parallel and located on the same plane; the angle between the downhill track (1) and the drain ramp (5) and the ground is 12°-25°.

[0009] Preferably, the preparation platform, the oil discharge ramp, and the oil collection tank are all connected by welding.

[0010] Preferably, an oil drain valve is provided at one end of the oil collection tank.

[0011] Preferably, both the oil discharge ramp and the oil collection tank are open-top structures.

[0012] Preferably, the downhill track is located in the downhill track section of the paint spraying line.

[0013] Preferably, a support frame is installed at the bottom of the oil receiving device, and there is a height difference between the support frame at the bottom of the preparation platform and the support frame at the end of the oil discharge slope.

[0014] A method for draining transmission fluid, comprising,

[0015] The transmission is suspended on a downhill track and adjusted to a downhill position. The transmission oil plug is removed to drain the oil. During testing, the oil flows out through the oil hole and slides up the drain ramp, collecting in the oil collection tank. When the transmission's downhill position becomes horizontal, it enters the oil collection tank area. Oil control, cleaning, and reinstalling the oil plug are then performed, completing the draining process.

[0016] Preferably, when the test oil reaches the set level, it is discharged into the designated device through the drain valve on the oil collection tank.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] This invention provides a method and apparatus for draining transmission oil. The method involves suspending the transmission on a downhill track, adjusting the transmission to a downhill position at the track, removing the oil plug, draining the oil through an oil hole, and collecting the test oil in an oil collection tank. This solves the problems of the transmission not being grounded, difficulty in completely draining residual test oil during operation, and the high labor intensity of repeated transmission runs. It allows residual test oil to settle without affecting production and enables secondary draining, improving the after-sales quality of the transmission. To effectively receive and collect the secondary drained test oil during operation, an oil receiving device is designed based on the downhill track of the painting line. This includes a horizontal preparation section before draining, a slope during draining, oil control after draining, and a transmission test oil collection section, allowing for direct draining of oil without stopping the transmission and enabling the collection and recycling of the test oil.

[0019] Furthermore, since the secondary oil draining occurs after painting, the residual test oil in the gearbox is relatively small. A downhill track is designed at a reasonable position on the painting line. The angle between the downhill track and the oil draining ramp and the ground is 12°-25°. The presence of the downhill track can allow the dispersed test oil to gather again and flow out well through the oil hole.

[0020] Furthermore, the distance between the transmission's ground clearance and its working height on the production line was adjusted. The reasonable position of the downhill track allows the transmission to reach the production line area more cleanly during the second oil draining, facilitating manual operation and achieving better oil draining requirements.

[0024] The present invention will be further described in detail below with reference to specific embodiments. These descriptions are for explanation purposes only and are not intended to limit the scope of the invention.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0026] A transmission oil draining device, such as Figure 1 and Figure 2 As shown, it includes a gearbox 2, an oil receiving device 3, and a downhill track 1.

[0027] The oil receiving device 3 includes an oil drain ramp 5 and an oil collection tank 6. The transmission 2 is suspended on the downhill track 1, and the oil receiving device is placed parallel to the bottom of the downhill track. The oil collection tank 6 is located at the end of the oil drain ramp 5. The oil receiving device also includes a preparation platform 4, which is located at the front end of the oil drain ramp 5. One end of the oil collection tank 6 is equipped with an oil drain valve 7. This painting line takes 2.5 hours from the loading box to the unloading box. The painting line running time is used as the transmission oil draining and settling time, which solves the problem of settling residual test oil during operation without grounding the transmission. This achieves the purpose of settling residual test oil and performing secondary oil draining without affecting production.

[0028] The downhill track 1 is located in the downhill section of the paint spraying line; the downhill track 1 of the paint spraying line facilitates oil draining and better completes the gearbox unloading work; the paint spraying line track is downhill;

[0029] Tilting transmission 2: The tilting posture allows for better collection of residual test oil;

[0030] Oil receiving device 3: adapts to the operation of the transmission, receives the discharged test oil, and collects and recycles it;

[0031] Preparation Platform 4: Facilitates the removal of the oil plug and the start of oil draining;

[0032] Oil drain ramp 5: Adapts to the tilt of the transmission and guides the received test oil to the oil collection tank.

[0033] Oil collection tank 6: On the one hand, it realizes the oil control and oil plug assembly of the transmission, and on the other hand, it facilitates the collection of test oil;

[0034] Oil drain valve 7: After the test oil in the oil collection tank reaches a certain level, it is collected through the oil drain valve for recycling.

[0035] A slide rail is installed on the downhill track 1 of the paint spraying line, and a pulley is installed on the slide rail. The gearbox 2 is suspended on the downhill track 1 of the paint spraying line through a suspension component. The movement of the pulley on the slide rail synchronously drives the movement of the gearbox 2.

[0036] Preferably, the centerline of the drain ramp, the centerline of the drain hole of the transmission, and the centerline of the downhill track are parallel to each other and lie on the same plane;

[0037] The connections between the preparation platform 4, the oil drain ramp 5, and the oil collection tank 6 are all welded together. The preparation platform 4, the oil drain ramp 5, and the oil collection tank 6 are all open-slot structures.

[0038] An oil drain hole is provided on the oil collection tank 6, and an oil drain valve 7 is installed on the oil drain hole.

[0039] The angle between the spray painting downhill track and the oil drain ramp 5 and the ground is 12°-25°. The angle of the spray painting downhill track and the oil drain ramp 5 should not be too large to ensure that the test oil can be smoothly discharged from the oil drain hole f. If the angle is too large, the test oil will flow into the rear cover, resulting in incomplete oil draining.

[0040] The bottom of the oil receiving device 3 is equipped with a support frame. The support frame at the bottom of the preparation platform 4 and the support frame at the end of the oil discharge ramp 5 have a height difference, which ensures that the oil discharge ramp 5 has a certain inclination angle so that the oil can smoothly enter the oil collection tank 6.

[0041] As one of the preferred embodiments of the present invention, the height of the oil collection tank 6 on the ground is 100mm, and the depth of the preparation platform 4, the oil discharge ramp 5 and the oil collection tank 6 is 52mm or 43mm.

[0042] As one of the preferred embodiments of the present invention, the oil discharge effect is best when the angle between the spray painting downhill track and the oil discharge ramp 5 and the ground is 16°.

[0043] A method for draining transmission fluid, comprising,

[0044] The transmission is suspended on the painting line track. When the painted transmission reaches preparation platform 4, the transmission oil plug is removed, and oil draining begins. The transmission is then moved to the downhill section of the painting line track and adjusted to a downhill position. The transmission oil plug is removed again, and the oil is drained through the oil hole. The test run oil collects in the oil collection tank. When the transmission finishes its downhill run and becomes horizontal, it enters the oil collection tank area for oil control, cleaning, and oil plug installation. When the test run oil reaches a certain level, it is discharged into the designated device through the drain valve 7.

[0045] The second oil draining process, such as Figure 1 The transmission undergoes a painting process, allowing residual test oil to settle completely. After painting, a second oil draining is performed before the transmission is packaged and ready for shipment. The downhill track of the painting line facilitates the collection and drainage of the settled test oil, and the designed oil collection device below the downhill track better collects the residual test oil. Furthermore, the distance between the transmission's ground clearance and its off-line working height has been adjusted, allowing it to directly enter the packaging area after draining, resulting in a more rational production line layout.

[0046] A more reasonable oil receiving device was designed based on the downhill track of the painting line. During the operation of the production line, when the painted transmission reaches the preparation platform 4, the transmission oil plug is removed and the oil is drained. Then the transmission assembly is in a downhill position for oil draining. At this time, the static test oil gathers again towards the oil hole and is discharged through the oil hole. The oil draining ramp adapts to the downhill track of the painting line and guides the collected test oil to the oil collection tank. When the transmission finishes its downhill descent and becomes horizontal, it enters the oil collection tank area for oil control, cleaning, and oil plug installation. The transmission is then taken off the production line. At this time, the test oil gathers in the oil collection tank. When the test oil reaches a certain level, it is discharged into a designated device through the drain valve and recycled after treatment.
