Description

Technical Field

[0001] The present invention relates to the technical field of automobile manufacturing, and particularly relates to a processing device for a fuel tank fuel pump. Background Art

[0002] At present, during the general assembly fuel tank sub-assembly process in automobile production, it is necessary to manually tighten the locking chuck of the fuel tank fuel pump. In actual work, an operator uses an extension rod about 800 mm long to load on the tightening chuck tool to tighten the locking chuck of the fuel pump. Since the torque of the locking chuck of the fuel pump is large, and most of the locking chuck seals are made of engineering plastics, it is even necessary to heat the sealing ring of the locking chuck at low temperatures before the assembly can be completed. Such an operation not only increases the energy consumption of the factory but also expands the safety risk points. At the same time, affected by production orders, enterprises carry out mixed-flow operations for fuel tank sub-assembly of different vehicle models. The specifications and sizes of fuel pumps are different, the external dimensions of fuel tanks vary greatly, and the fuel filling port directions and fuel pump installation positions of fuel tanks are also different, which brings many inconveniences to the general assembly fuel tank sub-assembly.

[0003] In addition, after the fuel tank sub-assembly is completed, it is also necessary to manually detect various parameters after the fuel pump is installed and detect the air tightness of the fuel tank. The manual detection method for the resistance value and air tightness leakage also has the problems of cumbersome steps and low efficiency.

[0004] Therefore, it is necessary to improve the general assembly fuel tank sub-assembly operation and improve the assembly efficiency on the basis of ensuring the assembly quality. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a processing device for a fuel tank fuel pump, which can improve the installation quality and assembly efficiency of the fuel tank fuel pump.

[0006] The technical solution of the present invention provides a processing device, including a tightening assembly, a base, a bearing platform, and a clamping assembly. The bearing platform is installed above the base. The bearing platform is used for placing the workpiece to be processed. The clamping assembly is installed on the bearing platform and is used to clamp the workpiece to be processed on the bearing platform.

[0007] The tightening assembly is located above the bearing platform. The tightening assembly includes a fixed bracket, a sky rail, a tightening moving unit, and a tightening unit. The sky rail is fixedly connected to the fixed bracket. The tightening moving unit is connected to the sky rail and is used to drive the tightening unit to move towards or away from the workpiece to be processed. The tightening unit is used to tighten the locking cover on the workpiece to be processed.

[0008] Further, the clamping assembly includes a clamping cylinder, a mounting bracket, a clamping link rod, and a clamping block. The mounting bracket is fixedly connected to one side of the carrying platform. The clamping cylinder is fixedly connected to the mounting bracket. The telescopic rod of the clamping cylinder is rotatably connected to one end of the clamping link rod. The middle section of the clamping link rod is rotatably connected to the mounting bracket. The other end of the clamping link rod is connected to the clamping block;

[0009] When the workpiece to be processed does not enter the carrying platform, the clamping link rod flips outward relative to the carrying platform;

[0010] When the workpiece to be processed enters the carrying platform, the clamping link rod flips inward relative to the carrying platform, and the clamping block contacts the workpiece to press the workpiece against the carrying platform.

[0011] Further, it further includes a transition flipping assembly. The transition flipping assembly includes a transition flipping cylinder, a transition flipping link rod, and a transition flipping plate. The transition flipping cylinder is connected to one end of the transition flipping link rod. The other end of the transition flipping link rod is connected to the transition flipping plate. The transition flipping plate is hinged to the other side of the carrying platform relative to the clamping assembly;

[0012] When the workpiece to be processed does not enter the carrying platform, the transition flipping plate and the carrying platform are in the same plane;

[0013] When the workpiece to be processed moves from one side of the transition flipping plate towards the carrying platform, the transition flipping cylinder drives the transition flipping plate to flip upward relative to the carrying platform and pushes the workpiece onto the carrying platform.

[0014] Further, it further includes a pushing assembly. The pushing assembly is arranged on the side of the carrying platform perpendicular to the side where the clamping assembly is located;

[0015] The pushing assembly includes a push plate, a sliding plate, a guide rod, and a rodless cylinder. The push plate is perpendicular to the carrying platform. The push plate is connected to the sliding plate. The sliding plate is arranged parallel to the carrying platform and is located below the carrying platform. The guide rod is along the length direction of the carrying platform. The rodless cylinder drives the sliding plate to slide along the guide rod, and the push plate pushes the workpiece out of the carrying platform.

[0016] Further, a connecting piece is provided on the sliding plate. The connecting piece is connected between the sliding plate and the push plate. The carrying platform includes a plurality of spaced-apart carrying plates. The connecting piece is inserted into the gap between adjacent carrying plates.

[0017] Further, it further includes a detection mechanism, which includes a detection bracket, a detection moving unit, and a detection head. The detection bracket is installed on the carrier table. The detection moving unit is installed on the detection bracket and is used to drive the detection head to move. The detection head is used to detect the resistance value on the workpiece to be processed.

[0018] Further, the detection bracket includes two L-shaped rods, a transverse rod, a first special-shaped leg, and a second special-shaped leg. One end of each of the two L-shaped rods is connected to both ends of the transverse rod respectively. The other ends of the two L-shaped rods are connected to one side of the carrier table. One end of the first special-shaped leg is connected to one end of the transverse rod, and the other end of the first special-shaped leg is connected to the opposite side of the carrier table. One end of the second special-shaped leg is connected to the other end of the transverse rod, and the other end of the second special-shaped leg is connected to the opposite side of the carrier table.

[0019] Further, it further includes a flipping mechanism, which includes a flipping motor and a flipping bracket. The flipping bracket is connected to the base. The flipping motor is installed on the flipping bracket and is connected to the carrier table.

[0020] Further, it further includes a lifting mechanism, which includes a lifting motor. The lifting motor is installed on the base, and the lifting rod of the lifting motor passes through the base and is connected to the flipping bracket;

[0021] When the lifting rod extends upward, the lifting rod drives the flipping bracket to lift upward;

[0022] When the lifting rod retracts downward, the lifting rod drives the flipping bracket to fall back onto the base.

[0023] Further, the workpiece to be processed is a fuel tank fuel pump, and the fuel tank fuel pump is provided with a fuel injection port. The locking cover is used to lock the fuel injection port.

[0024] After adopting the above technical solution, the following beneficial effects are achieved:

[0047] The following further illustrates the specific embodiments of the present invention with reference to the accompanying drawings.

[0048] It is easy to understand that according to the technical solution of the present invention, under the premise of not changing the essence of the present invention, there are various structural ways and implementation ways that can be mutually replaced by those of ordinary skill in the art. Therefore, the following specific embodiments and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the invention.

[0049] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined relative to the structures shown in the respective drawings. They are relative concepts and may therefore change accordingly depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0050] In some embodiments of the present invention, as Figures 1-2 shown, the processing device includes a tightening assembly 1, a base 2, a bearing table 3 and a clamping assembly 4. The bearing table 3 is installed above the base 2. The bearing table 3 is used to place the workpiece to be processed 10. The clamping assembly 4 is installed on the bearing table 3 and is used to clamp the workpiece to be processed 10 on the bearing table 3;

[0051] The tightening assembly 1 is located above the bearing table 3. The tightening assembly 1 includes a fixed bracket 11, a sky rail 12, a tightening moving unit 13 and a tightening unit 14. The sky rail 12 is fixedly connected to the fixed bracket 11. The tightening moving unit 13 is connected to the sky rail 12 and is used to drive the tightening unit 14 to move towards or away from the workpiece to be processed 10. The tightening unit 14 is used to tighten the locking cover 101 on the workpiece to be processed 10.

[0052] Specifically, as Figure 1As shown, the base 2 is located at the bottommost position. The base 2 is fixed on the ground or the workbench surface, providing support for the bearing platform 3 and the clamping assembly 4 installed above. The base 2 includes two crossbars, four diagonal braces, and two vertical frame structures.

[0053] The bearing platform 3 is installed above the base 2. The bearing surface of the bearing platform 3 is used to place the workpiece 10 to be processed. In this embodiment, the workpiece 10 to be processed is a fuel tank fuel pump.

[0054] After the workpiece 10 to be processed is placed on the bearing platform 3, there are two sets of clamping assemblies 4, which respectively clamp the left and right parts of the workpiece 10, so that the workpiece 10 is pressed tightly on the bearing platform 3.

[0055] As Figure 2 shown, the tightening assembly 1 is not connected to the base 2. The tightening assembly 1 is suspended above the bearing platform 3. The tightening assembly 1 includes a fixed bracket 11, a sky rail 12, a tightening moving unit 13, and a tightening unit 14.

[0056] Among them, the fixed bracket 11 includes two vertical frame structures. The fixed bracket 11 is fixedly connected to the ceiling or the upper suspension.

[0057] The sky rail 12 is a rectangular frame structure along the horizontal plane. The tightening moving unit 13 can slide back and forth along the sky rail 12.

[0058] The tightening moving unit 13 includes an X-direction moving component 131, a Y-direction moving component 132, and a Z-direction moving component 133. The X-direction moving component 131 can slide back and forth along the sky rail 12. The Y-direction moving component 132 can slide left and right relative to the X-direction moving component 131. The Z-direction moving component 133 is connected to the Y-direction moving component 132. The tightening unit 14 is connected to the Z-direction moving component 133 and can slide up and down relative to the Z-direction moving component 133. Therefore, through the X-direction moving component 131, the Y-direction moving component 132, and the Z-direction moving component 133, the tightening unit 14 can be adjusted in the three directions of up and down, left and right, and front and back, and the tightening unit 14 can be moved towards or away from the workpiece 10 to be processed.

[0059] When it is necessary to tighten the locking cover 101 of the workpiece 10 to be processed, the tightening moving unit 13 controls the tightening unit 14 to insert into the locking cover 101. Then, the tightening unit 14 drives the locking cover 101 to rotate to achieve the tightening of the locking cover 101.

[0060] Furthermore, as Figure 2 shown, the tightening unit 14 includes a servo motor 141, a fixed seat 142, a detection switch 143, and a tightening disc 144.

[0061] The fixed seat 142 is connected to the Z-direction moving component 133 and can move in the up-and-down direction relative to the Z-direction moving component 133. The servo motor 141, the detection switch 143, and the tightening disc 144 are all installed on the fixed seat 142. The servo motor 141 is used to drive the tightening disc 144 to rotate.

[0062] The tightening disc 144 is provided with a plurality of convex teeth, and the tightening moving unit 13 drives the convex teeth of the tightening disc 144 to insert into the locking cover 101. Then, the servo motor 141 drives the tightening disc 144 to rotate, and the tightening disc 144 drives the locking cover 101 to rotate together, so as to realize the tightening of the locking cover 101. The detection switch 143 is used to detect whether the locking cover 101 is tightened in place. When it is detected that it has been tightened in place, the detection switch 143 sends a signal to the servo motor 141, and the servo motor 141 stops rotating. The tightening moving unit 13 drives the tightening unit 14 to rise, so that the tightening disc 144 is separated from the locking cover 101.

[0063] Preferably, an audible and visual alarm prompt is provided at the detection switch 143.

[0064] Preferably, a visual inspection mechanism for photographing the locking cover 101 is further provided at the tail end of the tightening disc 144, and the visual inspection mechanism is connected to the PLC control system.

[0065] Preferably, as Figure 2 shown, the tightening unit 14 further includes a positioning member 145. The tail end of the positioning member 145 is provided with an elastic pin, and the positioning member 145 is located on the side of the tightening disc 144.

[0066] As Figure 1 shown, the workpiece 10 to be processed is further provided with a positioning hole 102. When the positioning member 145 is inserted into the positioning hole 102, the tightening disc 144 is aligned with the locking cover 101. However, at this time, the convex teeth of the tightening disc 144 may not have been inserted into the locking cover 101 yet. By rotating the servo motor 141 to drive the convex teeth of the tightening disc 144 to be aligned with the card slots on the locking cover 101, the convex teeth can be accurately inserted into the card slots. Therefore, the positioning member 145 can realize the precise and rapid positioning of the tightening disc 144.

[0067] Furthermore, as Figure 5 shown, the clamping assembly 4 includes a clamping cylinder 41, a mounting bracket 42, a clamping link 43, and a clamping block 44. The mounting bracket 42 is fixedly connected to one side of the carrying platform 3. The clamping cylinder 41 is fixedly connected to the mounting bracket 42. The telescopic rod of the clamping cylinder 41 is rotatably connected to one end of the clamping link 43. The middle section of the clamping link 43 is rotatably connected to the mounting bracket 42. The other end of the clamping link 43 is connected to the clamping block 44;

[0068] When the workpiece 10 to be processed does not enter the carrying platform 3, the clamping link 43 flips outwards relative to the carrying platform 3;

[0069] When the workpiece 10 to be processed enters the bearing platform 3, the clamping link 43 flips inward relative to the bearing platform 3, and the clamping block 44 contacts the workpiece 10 to press the workpiece 10 tightly on the bearing platform 3.

[0070] Specifically, as Figure 5 shown, two sets of clamping assemblies 4 are installed on the front side of the bearing platform 3, and the two sets of clamping assemblies 4 move synchronously to realize synchronous clamping or loosening of the workpiece 10 to be processed.

[0071] Among them, the mounting bracket 42 of the clamping assembly 4 is fixedly connected to the bearing platform 3, and the clamping cylinder 41 is fixedly installed on the mounting bracket 42. The extending end of the telescopic rod of the clamping cylinder 41 is rotatably connected to one end of the clamping link 43. When the telescopic rod expands and contracts, it can drive the swinging of the clamping link 43. The middle section of the clamping link 43 is rotatably connected to the mounting bracket 42, and this connection point serves as the rotation center of the clamping link 43. The other end of the clamping link 43 is connected to the clamping block 44, and the clamping link 43 extends the clamping block 44 towards the direction of the workpiece 10. When the clamping link 43 swings downward, the clamping block 44 can contact the workpiece 10 to realize clamping of the workpiece 10 to be processed.

[0072] When the workpiece 10 to be processed does not enter the bearing platform 3, the telescopic rod of the clamping cylinder 41 retracts, driving the clamping link 43 to flip upward and outward, and the clamping block 44 is lifted upward;

[0073] When the workpiece 10 to be processed enters the bearing platform 3, the telescopic rod of the clamping cylinder 41 extends upward, driving the clamping link 43 to flip downward and inward, and the clamping block 44 presses downward on the upper surface of the workpiece 10, thereby pressing the workpiece 10 tightly on the bearing platform 3.

[0074] Preferably, the clamping block 44 is inclined and installed towards the direction of the workpiece 10 to facilitate pressing the workpiece 10 from top to bottom. The clamping block 44 can be made of an elastic material to avoid damage to the workpiece 10 to be processed.

[0075] Furthermore, as Figures 3-5 shown, it further includes a transition flipping assembly 5. The transition flipping assembly 5 includes a transition flipping cylinder 51, a transition flipping link 52, and a transition flipping plate 53. The transition flipping cylinder 51 is connected to one end of the transition flipping link 52, the other end of the transition flipping link 52 is connected to the transition flipping plate 53, and the transition flipping plate 53 is hinged to the other side of the bearing platform 3 relative to the clamping assembly 4;

[0076] When the workpiece 10 to be processed does not enter the bearing platform 3, the transition flipping plate 53 and the bearing platform 3 are in the same plane;

[0077] When the workpiece 10 to be processed moves from one side of the transition turning plate 53 towards the carrier 3, the transition turning cylinder 51 drives the transition turning plate 53 to turn upwards relative to the carrier 3 and pushes the workpiece 10 onto the carrier 3.

[0078] Specifically, as Figures 3-4 shown, the transition turning assembly 5 is arranged on the rear side surface of the carrier 3. When the workpiece 10 is translated into the carrier 3 from the rear side, the transition turning assembly 5 turns in the reverse direction of the carrier 3 and pushes the workpiece 10 onto the carrier 3.

[0079] As Figure 5 shown, the transition turning assembly 5 includes a transition turning cylinder 51, a transition turning connecting rod 52 and a transition turning plate 53. Among them, the transition turning cylinder 51 is installed on the side surface of the carrier 3. The extending end of the telescopic rod of the transition turning cylinder 51 is rotatably connected to one end of the transition turning connecting rod 52. The other end of the transition turning connecting rod 52 is rotatably connected to the transition turning plate 53. The connection part between the transition turning connecting rod 52 and the transition turning plate 53 is also hinged to the carrier 3.

[0080] Figure 5 In

[0081] the transition turning plate 53 and the carrier 3 are on the same horizontal plane, and the workpiece 10 is translated from the direction where the transition turning plate 53 is located towards the direction of the carrier 3.

[0082] Furthermore, as Figures 6-7 shown, it further includes a pushing-out assembly 6. The pushing-out assembly 6 is arranged on the side surface of the carrier 3 perpendicular to the side where the clamping assembly 4 is located;

[0083] The pushing-out assembly 6 includes a push plate 61, a sliding plate 62, a guide rod 63 and a rodless cylinder 64. The push plate 61 is perpendicular to the carrier 3. The push plate 61 is connected to the sliding plate 62. The sliding plate 62 is arranged parallel to the carrier 3 and is located below the carrier 3. The guide rod 63 is along the length direction of the carrier 3. The rodless cylinder 64 drives the sliding plate 62 to slide along the guide rod 63, and the push plate 61 pushes the workpiece 10 out of the carrier 3.

[0084] Specifically, in this embodiment, the pushing-out assembly 6 is arranged on the right side of the carrier 3. The pushing-out assembly 6 is used to push the workpiece 10 out from the left side of the carrier 3, facilitating the transfer of the workpiece 10 to the next processing station.

[0085] As Figure 7As shown in the figure, the pushing component 6 includes a push plate 61, a sliding plate 62, a guide rod 63, and a rodless cylinder 64. Among them, the sliding plate 62, the guide rod 63, and the rodless cylinder 64 are all located below the bearing platform 3. The guide rod 63 and the rodless cylinder 64 are arranged along the left-right direction of the bearing platform 3. The sliding plate 62 is installed between the two guide rods 63 and is erected above the rodless cylinder 64. The push plate 61 is fixedly connected to the sliding plate 62, and the push plate 61 is perpendicular to the bearing platform 3.

[0086] Figure 7 When the pushing component 6 is not working, the push plate 61 is located on the right side of the bearing platform 3.

[0087] When the workpiece 10 to be processed needs to be removed from the bearing platform 3, the rodless cylinder 64 drives the sliding plate 62 to slide along the guide rod 63. The sliding plate 62 slides from right to left, and the push plate 61 pushes the workpiece 10 to be pushed out of the bearing platform 3 from right to left.

[0088] Furthermore, as Figures 6-7 shown, a connecting piece 621 is provided on the sliding plate 62. The connecting piece 621 is connected between the sliding plate 62 and the push plate 61. The bearing platform 3 includes multiple spaced bearing plates 31. The connecting piece 621 is inserted into the gap between adjacent bearing plates 31.

[0089] Specifically, as Figure 6 shown, the bearing platform 3 includes three bearing plates 31, and there are gaps between adjacent bearing plates 31. The connecting piece 621 just passes through the gap, so that the connecting piece 621 is flush with the upper surface of the bearing plate 31. When the sliding plate 62 drives the push plate 61 to slide, there will be no interference with the connecting piece 621.

[0090] Furthermore, as Figure 8 shown, a detection mechanism 7 is further included. The detection mechanism 7 includes a detection bracket 71, a detection moving unit 72, and a detection head 73. The detection bracket 71 is installed on the bearing platform 3, the detection moving unit 72 is installed on the detection bracket 71, the detection moving unit 72 is used to drive the detection head 73 to move, and the detection head 73 is used to detect the resistance value on the workpiece 10.

[0091] When the workpiece 10 to be processed is clamped by the clamping component 4 and the locking cover 101 is tightened by the tightening component 1. The detection moving unit 72 drives the detection head 73 to move towards the workpiece 10, and the detection head 73 is inserted into the electrical inspection port of the workpiece 10 to detect the resistance value of the workpiece 10.

[0092] Preferably, an audible and visual alarm prompt is provided at the detection head 73.

[0093] Furthermore, as Figure 8As shown in the figure, the detection bracket 71 includes two L-shaped rods 711, a transverse rod 712, a first special-shaped leg 713 and a second special-shaped leg 714. One ends of the two L-shaped rods 711 are respectively connected to two ends of the transverse rod 712, and the other ends of the two L-shaped rods 711 are connected to one side of the bearing platform 3. One end of the first special-shaped leg 713 is connected to one end of the transverse rod 712, and the other end of the first special-shaped leg 713 is connected to the opposite side of the bearing platform 3. One end of the second special-shaped leg 714 is connected to the other end of the transverse rod 712, and the other end of the second special-shaped leg 714 is connected to the opposite side of the bearing platform 3.

[0094] Specifically, the L-shaped rod 711 is connected to the front side of the bearing platform 3, the transverse rod 712 is located above the rear side of the bearing platform 3, and a space is left between the transverse rod 712 and the bearing platform 3 for the workpiece 10 to be processed to enter the bearing platform 3.

[0095] The first special-shaped leg 713 is connected to the left side of the bearing platform 3, and the second special-shaped leg 714 is connected to the right side of the bearing platform 3. Since a fuel pipe is connected to the workpiece 10 to be processed, in order to avoid interference with the fuel pipe, the first special-shaped leg 713 and the second special-shaped leg 714 are designed as irregular rod structures.

[0096] Preferably, as Figure 8 shown, the detection moving unit 72 includes an X-direction detection moving component 721, a Y-direction detection moving component 722 and a Z-direction detection moving component 723. Among them, the X-direction detection moving component 721 is installed on the L-shaped rod 711, the Y-direction detection moving component 722 is installed on the transverse rod 712, the Z-direction detection moving component 723 is installed on the Y-direction detection moving component 722, and the detection head 73 is installed on the Z-direction detection moving component 723. The detection head 73 moves up and down relative to the Z-direction detection moving component 723, the Z-direction detection moving component 723 moves left and right relative to the Y-direction detection moving component 722, and the Y-direction detection moving component 722 moves back and forth relative to the X-direction detection moving component 721. Thus, the movement adjustment of the detection head 73 in the three directions of XYZ is realized, and the electrical inspection port of the workpiece 10 to be processed can be accurately reached.

[0097] Furthermore, as Figure 9 shown, a flipping mechanism 8 is further included. The flipping mechanism 8 includes a flipping motor 81 and a flipping bracket 82. The flipping bracket 82 is connected to the base 2, the flipping motor 81 is installed on the flipping bracket 82, and the flipping motor 81 is connected to the bearing platform 3.

[0098] Specifically, the two flipping brackets 82 are respectively erected at the left and right ends of the base 2, and the flipping motor 81 is connected to one of the flipping brackets 82. The driving shaft of the flipping motor 81 is connected to the bearing platform 3. When the flipping motor 81 is driven, the bearing platform 3 is driven to flip. The other flipping bracket 82 is rotatably connected to the other side of the bearing platform 3 through a bearing.

[0099] After the inspection mechanism 7 inspects the workpiece 10 to be processed, the flipping mechanism 8 drives the workpiece 10 to be processed to flip 180°. Then, the inspection head 73 inspects the workpiece 10 to be processed again. After the inspection is completed, the flipping mechanism 8 drives the workpiece 10 to be processed to flip back to the original position.

[0100] Among them, when the carrier table 3 flips, the clamping assembly 4, the transition flipping assembly 5, the pushing assembly 6, and the inspection mechanism 7 installed on the carrier table 3 flip together.

[0101] Further, as Figure 9 shown, it further includes a lifting mechanism 9. The lifting mechanism 9 includes a lifting motor 91. The lifting motor 91 is installed on the base 2. The lifting rod 92 of the lifting motor 91 passes through the base 2 and is connected to the flipping bracket 82.

[0102] When the lifting rod 92 extends upward, the lifting rod 92 drives the flipping bracket 82 to lift upward.

[0103] When the lifting rod 92 retracts downward, the lifting rod 92 drives the flipping bracket 82 to fall back onto the base 2.

[0104] Specifically, the lifting mechanism 9 includes two groups, which are respectively installed at both ends of the base 2. The lifting motor 91 is installed vertically on the vertical frame of the base 2. The lifting rod 92 passes through the base 2 vertically and is connected to the bottom of the flipping bracket 82.

[0105] When the lifting mechanism 9 retracts, the flipping bracket 82 contacts the base 2, and the base 2 plays a supporting role for the flipping bracket 82.

[0106] Before the flipping mechanism 8 flips, the lifting motor 91 drives the lifting rod 92 to extend upward, and the lifting rod 92 drives the flipping bracket 82 to lift upward, and the flipping bracket 82 is separated from the base 2.

[0107] Then, the flipping mechanism 8 drives the carrier table 3 to flip, and the inspection mechanism 7 conducts an inspection. After the inspection is completed, the flipping mechanism 8 flips back to the original position, and the lifting mechanism 9 drives the flipping bracket 82 to descend and fall back onto the base 2.

[0108] In this embodiment, the workpiece 10 to be processed is a fuel tank fuel pump. The fuel tank fuel pump is provided with a fuel injection port, and the locking cover 101 is used to lock the fuel injection port. Optionally, the workpiece 10 to be processed can also be a workpiece that needs to be tightened and inspected.

[0109] In a preferred embodiment of the present invention, the working process of the processing device is as follows:

[0110] The workpiece 10 to be processed is first sent into the transition flipping assembly 5, and the transition flipping assembly 5 pushes the workpiece 10 to be processed into the carrier table 3. Then, the clamping assembly 4 presses the workpiece 10 to be processed tightly on the carrier table 3.

[0111] The execution parameters of the workpiece 10 to be processed are sent to the tightening moving unit 13 of the tightening assembly 1 in advance, and the tightening moving unit 13 drives the movement of the tightening unit 14 according to the parameters of the workpiece 10 to be processed.

[0112] When the tightening unit 14 moves to a position close to the locking cover 101. First, the positioning member 145 is inserted into the positioning hole 102 of the workpiece 10 to achieve precise positioning, and then the tightening disc 144 is inserted into the four slots of the locking cover 101. The tightening disc 144 is connected to the servo motor 141, and the servo motor 141 drives the tightening disc 144 to rotate clockwise. When the detection switch 143 detects that the torque of the tightening disc 144 reaches the set range, the Z-direction moving assembly 133 drives the tightening unit 14 to return to the standby position, and the locking operation ends. When the detection switch 143 detects that the torque does not reach the set range, the system issues an alarm prompt and stops working. The operator performs quality confirmation and checks the cause of the alarm, and performs manual tightening operation. After re-checking the tightening is completed, the Z-direction moving assembly 133 drives the tightening unit 14 to return to the standby position. At this time, the system starts the vision detection mechanism, takes a vision photo of the installation angle of the locking cover 101 for confirmation, and transmits the data to the upper computer for storage.

[0113] When the system detects that the Z-direction moving assembly 133 reaches the standby position, the detection mechanism 7 starts to work. The detection moving unit 72 moves with the detection head 73 according to the vehicle model information, and moves vertically downward with the detection head 73 after positioning. When the system detects that the detection head 73 is inserted into the electrical inspection port of the workpiece 10 in place, the control system issues an instruction to start the electrical inspection 0° position detection, and detects the sliding resistance value of the real-time oil pump. When the detected resistance value exceeds the set range, the system stops working and issues an audible and visual alarm to prompt the operator for manual confirmation. The operator replaces the new fuel pump and re-detects.

[0114] After the detected resistance value is within the process set range, the lifting mechanism 9 raises the flipping mechanism 8 and the carrier 3. When it is detected that the jacking is in place, the flipping mechanism 8 flips the entire detection mechanism 7, the workpiece 10 to be processed and the carrier 3 by 180°. After the system detects that the workpiece 10 to be processed is flipped in place, it issues an instruction to the control system, and the detection mechanism 7 detects the resistance value of the workpiece 10 to be processed at the 180° position. Similarly, when the detected real-time value is within the set range, the flipping mechanism 8 returns to the original position, otherwise an audible and visual alarm is issued. After the flipping mechanism 8 flips back to the original position, the lifting mechanism 9 returns to the original position, and the detection moving unit 72 drives the detection head 73 to pull out of the electrical inspection port. After the system confirms that all detections are in place, the clamping assembly 4 is opened, and the pushing assembly 6 pushes the workpiece 10 to be processed out of the carrier 3, completing a complete work process.

[0115] In the present invention, the automatic tightening of the locking cover can be achieved, reducing many inconveniences caused by manual operations. At the same time, the resistance value of the workpiece 10 to be processed can be detected, avoiding the low efficiency and poor quality caused by the mixed-flow operation of fuel tank sub-assembly for different vehicle models. The present invention integrates the tightening work and the detection function of the fuel pump of the fuel tank, improving the work efficiency and assembly quality.

[0116] The above are only the principles and preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, based on the principles of the present invention, several other variants can also be made, which should also be regarded as the protection scope of the present invention.
