Since the refueling machine is existing equipment and is not an innovation of this invention, the structure and working principle of the refueling machine will not be described in this specification.

[0033] like Figure 1 , Figure 5 , Figure 8 and Figure 9 As shown, the rotating mechanism 80 includes a rotating bracket 81, which is a rectangular structure arranged longitudinally. The front side of the rotating bracket 81 (the orientation referred to in this specification is...) Figure 1 (As shown) Two longitudinally arranged rotating mechanism guide rails 83 are installed in parallel. A rotating mechanism mounting plate 84 is fixed to the sliders of both rotating mechanism guide rails 83. A rotating mechanism moving cylinder 82 is installed on the side of the rotating bracket 81. The piston rod of the rotating mechanism moving cylinder 82 is fixedly connected to the rotating mechanism mounting plate 84, allowing the rotating mechanism mounting plate 84 to slide back and forth under the drive of the rotating mechanism moving cylinder 82. A rotary motor 87 is installed on the rotating mechanism mounting plate 84. The power output shaft of the rotary motor 87 is driven by a drive disc 86. Multiple drive docking holes 860 are evenly spaced around the edge of the drive disc 86, which are adapted to the rotary drive pins 96 on the gearbox 90. Four gearbox positioning pins 88 are installed on the rear side of the rotating bracket 81. The transmission 90 is placed on the rear side of the rotating bracket 81 via the transfer mechanism 20.

The rotating drive pin 96 on the transmission 90 is inserted into the corresponding drive docking hole 860, connecting the transmission 90 with the rotating motor 87. The rotating motor 87 drives the input shaft of the transmission 90 to rotate with the rotating motor 87, thereby simulating the working conditions of the transmission in the whole vehicle.

Four upper guide columns 422 are vertically fixed on the upper side of the upper clamping plate 421 at four corners respectively. The upper mounting plate 410 is provided with a guide hole corresponding to each of the four upper guide columns 422. When the piston rod of the upper clamping cylinder 420 is extended, the four upper guide columns 422 can stabilize the upper clamping plate 421, so as to stably clamp the transmission 90.

[0036] As shown in the drawings, Figure 1 , Figure 4 , Figure 8 and Figure 9 As shown in the drawings, the two sets of side clamping assemblies 44 are the same in structure and are mirror-imaged arranged. Herein, only one set is taken as an example for detailed description.

[0037] The side clamping assembly 44 comprises a side clamping cylinder 440 mounted outside the side mounting plate 414, the inner side of the side mounting plate 414 is fixed with a guide plate 441 corresponding to the position of the side clamping cylinder 440, and the piston rod of the side clamping cylinder 440 is connected with a side clamping plate 443 in sequence from outside to inside through the side mounting plate 414 and the guide plate 441.

The other end of the inclined transmission shaft 66 passes out of the transmission box 64 and is rotatably mounted on the other end of the inclined oiling rack base 61 through a bearing seat 67. Two rotating bracket connecting blocks 65 are fixedly sleeved on the inclined transmission shaft 66 between the transmission box 64 and the bearing seat 67. A rotating bracket 81 is fixedly mounted on the two rotating bracket connecting blocks 65. When the inclined motor 62 is started, the inclined transmission shaft 66 rotates, thereby driving the rotating bracket 81 to incline forward and backward.

[0042] As shown in the drawings, Figure 2 , Figure 3 , Figure 8 and Figure 9 ​​​As shown in the figures, the clamping assembly comprises two oppositely arranged mounting side plates 30, which are L-shaped. The lower ends of the second mounting suspension 272 are respectively provided with suspension rails 31. The horizontal plates of the two mounting side plates 30 are respectively fixed on the sliding blocks of the two suspension rails 31, so that the two mounting side plates 30 are slidingly mounted at the lower ends of the second mounting suspension 272.

The power output shaft of the X-direction moving motor 250 is connected with an X-direction moving gear 251 after penetrating through the first sliding mounting plate 260. A rack 252 is mounted on the cross beam 22 along the X-axis direction and is engaged with the X-direction moving gear 251. Two X-direction rails 253 are also mounted on the cross beam 22, which are respectively arranged on the two sides of the cross beam 22 and are parallel to the rack 252. The first sliding mounting plate 260 is fixed on the sliding blocks of the two X-direction rails 253. Since the rack 252 is fixed on the cross beam 22, when the X-direction moving motor 250 is started, the X-direction moving gear 251 will move along the rack 252, thereby driving the first sliding mounting plate 260 to slide in the X-axis direction.

An auxiliary cylinder 24 is mounted on each of the second sliding mounting plates 262 located on both sides of the outer beam 233, and the piston rods of the two auxiliary cylinders 24 are fixedly connected with both ends of the first mounting suspension 270 after penetrating through the second sliding mounting plates 262 and the first sliding mounting plate 260, thereby playing an auxiliary role and increasing the lifting load capacity of the Z-direction moving motor 230.

[0046] As shown in the drawings, Figure 1 , Figure 4 , Figure 5 andFigure 8 As shown, a fluid level sensor 45 is installed on the inner side of the side mounting plate 414 on the left side. The installation position of the fluid level sensor 45 corresponds to the position of the fluid level detection hole 98 after the transmission 90 is placed on the rotating bracket 81. It is used to detect whether the fluid in the transmission 90 is full. In this embodiment, the fluid level sensor 45 is preferably a color detection sensor. When the transmission 90 is full of fluid, the fluid will overflow from the fluid level detection hole 98. Since the color of the fluid is different from the color of the transmission 90 housing, when the fluid overflows from the fluid level detection hole 98, the fluid level sensor 45 will detect it and send the detected signal to the equipment controller (not shown in the figure). The equipment controller then controls the refueling machine to stop refueling.

[0050] The workflow of the transfer mechanism 20 in this step is as follows:

[0051] Step 1: The Z-axis moving motor 230 and the auxiliary cylinder 24 are started. After the clamping assembly is lowered to the position where the clamping column 34 is flush with the clamping process hole 94 of the transmission 90 on the tray 12, the piston rod of the clamping cylinder 32 retracts and the four clamping columns 34 are inserted into the four clamping process holes 94 respectively to clamp the transmission 90. Then the Z-axis moving motor 230 rotates in the opposite direction and the piston rod of the auxiliary cylinder retracts to lift the transmission 90.

[0052] Step 2: The X-axis moving motor 250 is started, and the transfer mechanism 20 drives the gearbox 90 to move along the X-axis to above the rotating bracket 81;

[0053] Step 3: Steering motor 290 starts, driving clamping assembly to rotate 90°, so that the drive end of transmission 90 faces rotary motor 87;

[0054] Step 4: Start the Y-axis moving motor 280 and adjust the position of the gearbox 90 in the Y-axis direction so that the gearbox 90 is aligned with the four gearbox positioning posts 88 on the rotating bracket 81.

[0055] Step 5: The Z-axis moving motor 230 and auxiliary cylinder 24 are started, driving the clamping assembly to move downward and place the gearbox 90 onto the four gearbox positioning posts 88.

[0056] Step S2, the piston rod of the moving cylinder 48 of the clamping mechanism is extended, and the clamping mechanism 40 is moved backward to a position corresponding to the transmission 90. The piston rod of the upper clamping cylinder 420 is extended, the upper clamping plate 421 is driven to press on the top of the transmission 90, and the piston rods of the two side clamping cylinders 440 are extended, and the four positioning columns 444 are respectively inserted into the four clamping process holes 94 of the transmission 90, so that the upper clamping assembly 42 and the two sets of side clamping assemblies 44 jointly clamp and fix the transmission 90 from three directions.

[0057] Step S3, the tilt motor 62 is started, the tilt transmission shaft 66 is driven to rotate clockwise, the rotating bracket 81 is tilted backward, and the transmission 90 is stopped after being tilted at an angle a. In the embodiment, the value of the angle a is determined according to the model of the transmission, and is usually 3°-6°.

[0058] Step S4, the oiling machine is started, and the transmission 90 is oiled through the oiling hole 92 on the transmission 90.

[0059] Step S5, after about 30s of oiling, the piston rod of the rotating mechanism moving cylinder 82 is extended, the rotating mechanism mounting slide plate 84 is driven to slide backward, the rotating motor 87 is moved to the transmission 90, and the rotating motor 87 starts to rotate at a very slow speed. The rotating motor 87 rotates while moving to the transmission 90, so as to determine that the rotating drive pin 96 on the transmission 90 can correspond to the drive docking hole 860 on the drive plate 86. When the rotating drive pin 96 is inserted into the corresponding drive docking hole 860, the transmission 90 is in transmission connection with the rotating motor 87, and the rotating speed of the rotating motor 87 is gradually increased to the rotating speed r.

[0060] Step S6, the input shaft of the transmission 90 rotates at the rotating speed r to simulate the running condition of the transmission 90 on the whole vehicle. The rotating speed r is the running speed of the transmission 90 on the whole vehicle, and is usually 2000 rad / min. The transmission 90 continues to be oiled while rotating.

[0061] Step S7, the liquid level detection sensor 45 detects the oiling amount of the transmission 90. When the liquid level detection sensor 45 detects that oil overflows at the liquid level detection hole 98 of the transmission 90, it is indicated that the oiling amount of the transmission 90 reaches the oiling requirement, and the oiling machine is stopped. The oiling amount is different according to different models of the transmission, and is usually 8L-11L.

[0062] Step S8, the rotating motor 87 stops rotating, the rotating mechanism moves the piston rod of the cylinder 82 to retract, the rotating motor 87 resets; the piston rods of the upper clamping cylinder 420 and the two sets of side clamping cylinders 440 are retracted, the upper clamping assembly 42 and the two sets of side clamping assemblies 44 release the transmission 90, the piston rod of the clamping mechanism moving cylinder 48 is retracted, and the clamping mechanism 40 resets; the tilting motor 62 rotates in the opposite direction, so that the transmission 90 returns to the horizontal position; the transfer mechanism 20 transfers the transmission 90 after oiling back to the tray 12 of the line body 10, thereby completing the oiling process of one transmission 90, wherein the working process of the transfer mechanism 20 moving back the transmission 90 is basically the same as step S1, and thus is not described in detail herein.

[0063] In summary, the transmission pre-delivery oiling method and device of the present application is not affected by the machining tolerance of transmission parts, ensures that the oiling amount of the transmission can meet the technical requirements, and ensures the normal operation of the whole vehicle.
