Description

Technical Field

[0002] The transmission, also known as the gearbox, is the main power component of the car and is used to change the speed and torque from the engine. Before the transmission leaves the factory, it needs to be pre-fueled. A reasonable amount of fuel can ensure the normal operation of the entire vehicle. If the amount of fuel is too much or too little, it will cause problems such as vehicle failure and damage to parts such as the clutch. At present, the weighing method is generally used to refuel the transmission. However, due to the certain tolerances in the size and weight of the various components of the transmission, the weight consistency of the assembled transmission assembly is poor, which leads to the weighing refueling method.

[0014] After adopting the above technical solution, the beneficial effects of the present invention are: The transmission refueling equipment before leaving the factory of the present invention comprises: a rotating mechanism, which comprises a rotating motor for driving the transmission to rotate; a clamping mechanism, which comprises an upper clamping assembly and a side clamping assembly for clamping and positioning the transmission from the top and both sides, and also comprises a clamping mechanism moving cylinder for driving the clamping mechanism to move forward and backward; a tilting refueling platform, which comprises a tilting motor for driving the rotating mechanism to tilt forward and backward; a transfer mechanism, which comprises a clamping assembly for clamping the transmission and a steering motor for driving the clamping assembly to rotate, and also comprises a three-way moving mechanism for driving the clamped assembly to transfer the transmission between the linear body and the rotating mechanism; a liquid level detection sensor for detecting whether the oil in the transmission is full.

[0016] To sum up, the method and equipment for refueling the transmission before leaving the factory of the present invention solves technical problems in the prior art such as the amount of refueling of the transmission before leaving the factory not meeting the requirements. The method and equipment for refueling the transmission before leaving the factory of the present invention will not be affected by the processing tolerances of the transmission parts, ensuring that the amount of refueling of the transmission can meet the technical requirements and ensuring the normal operation of the entire vehicle.

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0019] The directions mentioned in this specification are based on the directions shown in the drawings and only represent relative positions, not absolute positions. Embodiment 1

[0020] like Figure 1 and Figure 4As shown together, a transmission refueling device before leaving the factory includes a transfer mechanism 20, a clamping mechanism 40, a rotating mechanism 80, an inclined refueling platform 60, a liquid level detection sensor 45 and a refueling machine (not shown in the figure). Since the refueling machine is an existing equipment and is not the innovation of the present invention, the structure and working principle of the refueling machine are not elaborated in this specification.

[0021] like Figure 1 , Figure 5 , Figure 8 and Fig. 9 As shown in the figure, the rotating mechanism 80 includes a rotating bracket 81, which is a rectangular structure and is arranged longitudinally. The front side of the rotating bracket 81 (the orientation involved in this specification is as follows) Figure 1 Two longitudinally arranged rotating mechanism guide rails 83 are installed in parallel (see FIG. 1 ), and a rotating mechanism mounting slide plate 84 is fixed on the sliders of the two 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 slide plate 84. The rotating mechanism mounting slide plate 84 can slide forward and backward under the drive of the rotating mechanism moving cylinder 82. A rotating motor 87 is installed on the rotating mechanism mounting slide plate 84. The power output shaft of the rotating motor 87 is connected to the driving disk 86. The edge of the driving disk 86 is provided with a plurality of driving docking holes 860 at equal intervals in the circumferential direction. The driving docking holes 860 are adapted to the rotating driving pins 96 on the transmission 90. Four transmission positioning columns 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 through the transfer mechanism 20. The four transmission positioning columns 88 play a role in positioning the transmission 90. The piston rod of the rotating mechanism moving cylinder 82 is extended. The rotating mechanism mounting slide plate 84 drives the rotating motor 87 to slide backward together. The rotating drive pin 96 on the transmission 90 is inserted into the corresponding drive docking hole 860 to connect 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 condition of the transmission on the whole vehicle.

[0022] like Figure 1 , Figure 4 , Figure 5 , Figure 8 and Fig. 9As shown together, the clamping mechanism 40 includes a mounting frame composed of an upper mounting plate 410, a lower mounting plate 412 and two side mounting plates 414. An upper clamping assembly 42 is mounted on the upper mounting plate 410, and a set of side clamping assemblies 44 are mounted on each of the two side mounting plates 414. The two sets of side clamping assemblies 44 are arranged in a mirror image on the left and right sides. The upper clamping assembly 42 and the two sets of side clamping assemblies 44 together play a clamping and positioning role for the transmission 90 at the top and the left and right sides. A slider of the clamping mechanism guide rail 46 is fixedly set on the upper side of the lower mounting plate 412. In the present embodiment, two clamping mechanism guide rails 46 are provided, and the two clamping mechanism guide rails 46 are longitudinally parallel and fixedly mounted on the lower side of the rotating bracket 81. The clamping mechanism moving cylinder 48 is installed on the lower side of the rotating bracket 81 through the cylinder mounting frame. The piston rod of the clamping mechanism moving cylinder 48 is fixedly connected to the lower mounting plate 412 through the connecting block. When the piston rod of the clamping mechanism moving cylinder 48 is extended, the clamping mechanism 40 slides backward to the position corresponding to the transmission 90, and the transmission 90 can be clamped and positioned; when the piston rod of the clamping mechanism moving cylinder 48 is retracted, the clamping mechanism 40 slides forward to avoid the position of the transmission 90, so as to facilitate the transfer mechanism 20 to transfer the transmission 90.

[0023] like Figure 1 , Figure 4 , Figure 8 and Fig. 9 As shown together, the upper clamping assembly 42 includes an upper clamping cylinder 420 installed on the upper side of the upper mounting plate 410, and the piston rod of the upper clamping cylinder 420 passes through the upper mounting plate 410 from top to bottom and is connected to the upper clamping plate 421, and an upper guide column 422 is vertically fixed to each of the four corners on the upper side of the upper clamping plate 421, and a guide hole is respectively provided at the position corresponding to the four upper guide columns 422 on the upper mounting plate 410, and the four upper guide columns 422 slide through the corresponding guide holes respectively, and 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, thereby ensuring that the upper clamping plate 421 stably clamps the transmission 90.

[0024] like Figure 1 , Figure 4 , Figure 8 and Fig. 9 As shown in the figure, the two sets of side clamping assemblies 44 have the same structure and are arranged in a mirror-like manner on the left and right sides, so only one set is taken as an example for detailed description: The side clamping assembly 44 includes a side clamping cylinder 440 mounted on the outside of the side mounting plate 414, a guide plate 441 is fixed on the inside of the side mounting plate 414 at the position corresponding to the side clamping cylinder 440, and the piston rod of the side clamping cylinder 440 passes through the side mounting plate 414 and the guide plate 441 from the outside to the inside in sequence and is connected to the side clamping plate 443. Two positioning columns 444 are installed on the inside of the side clamping plate 443, and the two positioning columns 444 are adapted to the clamping process holes 94 of the transmission 90. When the piston rod of the side clamping cylinder 440 is extended, the positioning columns 444 will be inserted into the clamping process holes 94, and the transmission 90 will be clamped and positioned from the left and right sides. A side guide column 442 is installed on each of the two outer ends of the side clamping plate 443. Guide holes are provided on the guide plate 441 at positions corresponding to the two side guide columns 442. The two side guide columns 442 slide through the two guide holes respectively. When the piston rod of the side clamping cylinder 440 is extended, the two side guide columns 442 can ensure stable linear motion of the side clamping plate 443 and ensure that the positioning column 444 can be accurately inserted into the clamping process hole 94 of the transmission 90.

[0025] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown together, the inclined refueling platform 60 includes an inclined refueling platform base 61, which is arranged horizontally. A transmission box 64 is installed at one end of the inclined refueling platform base 61, and a vertically rotating worm rod 69 and a turbine 70 meshing with the worm rod 69 are installed in the transmission box 64. The upper end of the worm rod 69 passes through the transmission box 64 and is connected to the inclined motor 62 through the inclined platform coupling 68 and the inclined reducer 63. The turbine 70 is fixedly mounted on one end of a inclined transmission shaft 66, and the other end of the inclined transmission shaft 66 passes through the transmission box 64 and is rotatably installed on the other end of the inclined refueling platform base 61 through a bearing seat 67. Two rotating bracket connecting blocks 65 are fixedly sleeved at intervals on the tilt transmission shaft 66 located between the transmission box 64 and the bearing seat 67, and the rotating bracket 81 is fixedly mounted on the two rotating bracket connecting blocks 65. When the tilt motor 62 is started, the tilt transmission shaft 66 will rotate, thereby driving the rotating bracket 81 to tilt forward and backward, that is, the tilt motor 62 can drive the entire rotating mechanism 80 to tilt forward and backward.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 8 and Fig. 9As shown together, the transfer mechanism 20 includes a mounting frame consisting of a column 21 and a crossbeam 22, and the mounting frame is arranged in a bridge-like manner across the line body 10, the clamping mechanism 40, the rotating mechanism 80 and the tilting refueling platform 60. A three-way moving mechanism capable of reciprocating between the line body 10 and the rotating mechanism 80 is installed on the crossbeam 22, and a clamping assembly for clamping the transmission 90 is provided below the three-way moving mechanism, thereby realizing the transfer of the transmission 90 between the line body 10 and the rotating mechanism 80.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown together, the three-way moving mechanism includes a first sliding mounting plate 260 mounted on the crossbeam 22 and driven by the X-direction moving device to slide left and right, a second sliding mounting plate 262 driven by the Y-direction moving device to slide forward and backward mounted on the first sliding mounting plate 260, and a Z-direction moving device mounted on the second sliding mounting plate 262. The Z-direction moving device passes through the second sliding mounting plate 262 and the first sliding mounting plate 260 from top to bottom in sequence, and is connected to the first mounting suspension 270, a horizontally arranged steering motor 290 is mounted on the first mounting suspension 270, an active bevel gear 294 is mounted on the power output shaft of the steering motor 290, the active bevel gear 294 is meshed with a driven bevel gear 292, and the driven bevel gear 292 is connected to the second mounting suspension 272, a clamping assembly is mounted on the lower side of the second mounting suspension 272, and the steering motor 290 is used to drive the clamping assembly to rotate in the horizontal direction. Through the combined movement of the three-way moving mechanism and the steering motor 290, the clamping assembly can move in three directions: the X-axis direction, the Y-axis direction and the Z-axis direction, so as to find the position of the transmission 90 for clamping, and move the transmission 90 from the tray 12 of the line body 10 to the rotating mechanism 80, or move the transmission from the rotating mechanism 80 back to the tray 12 of the line body 10, and can rotate in the horizontal direction to adjust the posture of the transmission 90.

[0028] It should be noted that the X-axis direction in this specification is Figure 1 The left and right directions shown are also the horizontal directions; the Y-axis direction is Figure 1 The front-to-back direction is the longitudinal direction; the Z-axis direction is Figure 1 The up and down direction shown is also the vertical direction.

[0029] like Figure 2 , Figure 3 , Figure 8 and Fig. 9As shown together, the clamping assembly includes two mounting side plates 30 arranged opposite to each other, the two mounting side plates 30 are L-shaped, and the two ends of the lower side of the second mounting suspension 272 are respectively installed with suspension rails 31, and the horizontal plates of the two mounting side plates 30 are respectively fixed on the sliders of the two suspension rails 31, so that the two mounting side plates 30 are slidably installed on the two ends of the lower side of the second mounting suspension 272. A clamping column limit block 36 is installed on the second mounting suspension 272 located between the two mounting side plates 30, which is used to limit the sliding distance when the two mounting side plates 30 slide toward each other. Two clamping columns 34 are respectively installed on the inner lower part of the vertical plates of the two mounting side plates 30, and the clamping columns 34 are adapted to the clamping process holes 94 of the transmission 90. A clamping cylinder 32 is installed between the inner upper parts of the vertical plates of the two mounting side plates 30. The cylinder body and piston rod of the clamping cylinder 32 are respectively fixed on the vertical plates of the two mounting side plates 30. The transmission 90 can be clamped and released by extending and retracting the piston rod of the clamping cylinder 32.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown together, the X-direction moving device includes an X-direction moving motor 250 installed on the upper side of the first sliding mounting plate 260, and the power output shaft of the X-direction moving motor 250 passes through the first sliding mounting plate 260 and is connected to an X-direction moving gear 251, and a rack 252 is installed on the crossbeam 22 along the X-axis direction, and the rack 252 is meshed with the X-direction moving gear 251. Two X-direction guide rails 253 are also installed on the crossbeam 22, and the two X-direction guide rails 253 are respectively installed on both sides of the crossbeam 22, and both sides are arranged parallel to the rack 252, and the first sliding mounting plate 260 is fixed on the sliders of the two X-direction guide rails 253. Because the rack 252 is fixed on the crossbeam 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, and the X-direction guide rail 253 can ensure the stability and linearity of the sliding of the first sliding mounting plate 260.

[0031] like Figure 1 , Figure 2 and Figure 3As shown together, the Y-moving device includes a Y-moving motor 280 installed on the first sliding mounting plate 260, the power output shaft of the Y-moving motor 280 is drivingly connected with a Y-moving lead screw 281, the lead screw nut 282 is threadedly connected to the Y-moving lead screw 281, and the lead screw nut 282 is fixedly connected to the second sliding mounting plate 262. Two guide grooves 2600 are longitudinally parallel to each other on the upper surface of the first sliding mounting plate 260, and a guide strip (not shown in the figure) matching the guide grooves 2600 is protruded from the lower side of the second sliding mounting plate 262 to ensure that the second sliding mounting plate 262 moves smoothly in the Y-axis direction. After the Y-moving motor 280 is started, the Y-moving lead screw 281 rotates accordingly, and the lead screw nut 282 moves along the Y-moving lead screw 281, thereby driving the second sliding mounting plate 262 to slide along the guide grooves 2600.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown together, the Z-axis moving device includes an outer beam 233 fixedly mounted on the second sliding mounting plate 262. The outer beam 233 is vertically arranged and simultaneously passes through the second sliding mounting plate 262 and the first sliding mounting plate 260.

A guide column 2340 is provided on the side wall of the inner beam 234 at a position corresponding to the guide long hole 2330. The guide column 2340 is constrainedly installed in the guide long hole 2330, and plays a guiding role for the inner beam 234, thereby ensuring the smoothness and linearity of the movement of the inner beam 234. The top of the outer beam 233 is provided with a reducer mounting seat 232, on which a mobile reducer 231 is mounted, on which a Z-direction moving motor 230 is mounted, and the power output shaft of the Z-direction moving motor 230 is connected to a vertically arranged Z-direction moving lead screw (not shown in the figure) through the mobile reducer 231, and the inner beam 234 is threadedly connected to the Z-direction moving lead screw, and when the Z-direction moving motor 230 is started, the Z-direction moving lead screw rotates accordingly, and the inner beam 234 moves up and down along the Z-direction moving lead screw. The lower end of the inner beam 234 extends from the lower port of the outer beam 233 and is fixedly connected to the central part of the first mounting suspension 270, so that when the inner beam 234 moves up and down, it drives the first mounting suspension 270 to move up and down, and then drives the clamping assembly to move up and down. An auxiliary cylinder 24 is installed on each of the second sliding mounting plates 262 located on both sides of the outer beam 233. The piston rods of the two auxiliary cylinders 24 pass through the second sliding mounting plate 262 and the first sliding mounting plate 260 and are fixedly connected to the two ends of the first mounting suspension 270, playing an auxiliary role and increasing the lifting load capacity of the Z-axis moving motor 230.

[0033] like Figure 1 , Figure 4 , Figure 5 and Figure 8 As shown in the figure, a liquid level detection sensor 45 is installed on the inner side of the side mounting plate 414 located on the left side. The installation position of the liquid level detection sensor 45 corresponds to the position of the liquid level detection hole 98 of the transmission 90 after it is placed on the rotating bracket 81. It is used to detect whether the oil in the transmission 90 is full. In this embodiment, the liquid level detection sensor 45 is preferably a color detection sensor. When the transmission 90 is filled with oil, the oil will overflow from the liquid level detection hole 98. Because the color of the oil is different from the color of the transmission 90 shell, when there is oil overflowing from the liquid level detection hole 98, the liquid level detection sensor 45 will detect it and send the detected signal to the equipment controller (not shown in the figure), and the equipment controller will control the fuel dispenser to stop refueling. Embodiment 2

[0034] like Figures 1 to 9 As shown together, a transmission refueling method before delivery based on the transmission refueling device before delivery described in the first embodiment includes the following steps: Step S1 : The transfer mechanism 20 transfers the transmission 90 from the line body 10 to the rotating bracket 81 of the rotating mechanism 80 , and the transmission positioning column 88 on the rotating bracket 81 positions and supports the transmission 90 .

[0035] The working process of the transfer mechanism 20 in this step is as follows: Step 1: The Z-direction moving motor 230 and the auxiliary cylinder 24 are started, and the clamping assembly is lowered to a position where the clamping column 34 is flush with the clamping process hole 94 of the transmission 90 located on the pallet 12, and then the piston rod of the clamping cylinder 32 is retracted, and the four clamping columns 34 are respectively inserted into the four clamping process holes 94 to clamp the transmission 90, and then the Z-direction moving motor 230 rotates in the opposite direction, and the piston rod of the auxiliary cylinder is retracted to lift the transmission 90; Step 2: The X-axis moving motor 250 is started, and the transfer mechanism 20 drives the transmission 90 to move along the X-axis direction to the top of the rotating bracket 81; Step 3: The steering motor 290 is started to drive the clamping assembly to rotate 90° so that the driving end of the transmission 90 faces the rotating motor 87; Step 4: The Y-axis moving motor 280 is started to adjust the position of the transmission 90 in the Y-axis direction so that the transmission 90 is aligned with the four transmission positioning posts 88 on the rotating bracket 81; Step 5: The Z-axis moving motor 230 and the auxiliary cylinder 24 are started to drive the clamping assembly to move downward and place the transmission 90 on the four transmission positioning columns 88.

[0036] Step S2, the piston rod of the clamping mechanism moving cylinder 48 is extended, and the clamping mechanism 40 moves backward to the position corresponding to the transmission 90, and the piston rod of the upper clamping cylinder 420 is extended to drive the upper clamping plate 421 to press on the top of the transmission 90. At the same time, the piston rods of the two side clamping cylinders 440 are extended to insert the four positioning columns 444 into the four clamping process holes 94 of the transmission 90 respectively, 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.

[0037] Step S3, the tilt motor 62 is started, driving the tilt transmission shaft 66 to rotate clockwise, and the rotating bracket 81 tilts backward accordingly, and the transmission 90 stops after tilting at an angle a. In this embodiment, the value of the angle a is determined according to the type of the transmission, and is usually 3° to 6°.

[0038] Step S4, start the fuel dispenser and refuel the transmission 90 through the refueling hole 92 on the transmission 90.

[0039] Step S5, about 30 seconds after refueling, the piston rod of the rotating mechanism moving cylinder 82 extends, driving the rotating mechanism mounting slide plate 84 to slide backward, driving the rotating motor 87 to move toward the transmission 90, and at the same time, the rotating motor 87 starts to rotate at a very slow speed, rotating while moving toward the transmission 90 to ensure that the rotating drive pin 96 on the transmission 90 can correspond to the driving docking hole 860 on the driving disk 86. When the rotating drive pin 96 is inserted into the corresponding driving docking hole 860, the transmission 90 is connected to the rotating motor 87, and the speed of the rotating motor 87 gradually increases to the speed r rotation.

[0040] Step S6, the transmission 90 rotates at a speed r to simulate the operating condition of the transmission 90 on the vehicle. The speed r is the operating speed of the transmission 90 on the vehicle, which is usually 2000 rad / min. The transmission 90 continues to be refueled while it rotates.

[0041] Step S7, the liquid level detection sensor 45 detects the amount of oil added to the transmission 90. When the liquid level detection sensor 45 detects that oil is overflowing from the liquid level detection hole 98 of the transmission 90, it means that the amount of oil added to the transmission 90 has reached the refueling requirement, and the refueling machine is stopped. The amount of oil added varies according to the type of transmission, and is usually 8L to 11L.

[0042] Step S8, the rotating motor 87 stops rotating, the piston rod of the rotating mechanism moving cylinder 82 retracts, and the rotating motor 87 is reset; the piston rods of the upper clamping cylinder 420 and the two side clamping cylinders 440 are all 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 retracts, and the clamping mechanism 40 is reset; the tilting motor 62 rotates in the opposite direction to restore the transmission 90 to a horizontal position; the transfer mechanism 20 transfers the oiled transmission 90 back to the tray 12 of the line body 10, thereby completing the refueling process of a transmission 90, wherein the work flow of the transfer mechanism 20 moving the transmission 90 back is basically the same as step S1, so it will not be described in detail here.

[0043] In summary, the method and equipment for refueling the transmission before it leaves the factory of the present invention will not be affected by the machining tolerances of the transmission parts, ensuring that the refueling amount of the transmission can meet the technical requirements and ensuring the normal operation of the entire vehicle.

[0044] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work are all within the protection scope of the present invention.
