Description
Technical Field
[0001] This invention relates to the technical field of automobile manufacturing, and more particularly to a processing apparatus for a fuel pump in a fuel tank. Background Technology
[0002] Currently, during the final assembly of fuel tanks in automobile production, the locking chuck of the fuel pump needs to be manually tightened. In practice, operators use an extension rod of approximately 800 mm to tighten the locking chuck on a tightening tool. Because the locking chuck has a high torque and its sealing ring is mostly made of engineering plastics, it may even require heating the sealing ring before assembly, especially in low temperatures. This increases energy consumption and safety risks in the factory. Furthermore, due to production orders, fuel tank assembly for different vehicle models is often done in mixed processes. Fuel pump specifications and dimensions vary, fuel tank dimensions differ significantly, and the direction of the fuel filler neck and the installation position of the fuel pump also vary, causing numerous inconveniences for the final assembly of fuel tanks.
[0003] In addition, after the oil tank is reassembled, it is necessary to manually test various parameters of the oil pump after installation and test the airtightness of the oil tank. The manual testing method, which involves checking the resistance value and whether there is any leakage, is cumbersome and inefficient.
[0004] Therefore, it is necessary to improve the assembly process of the fuel tank sub-assembly, and increase assembly efficiency while ensuring assembly quality. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a processing device for fuel tank pumps, which can improve the installation quality and assembly efficiency of fuel tank pumps.
[0006] The present invention provides a processing device, including a tightening assembly, a base, a support platform, and a clamping assembly. The support platform is installed above the base and is used to place the workpiece to be processed. The clamping assembly is installed on the support platform and is used to clamp the workpiece to be processed on the support platform.
[0007] The tightening assembly is located above the support platform. The tightening assembly includes a fixed bracket, a top rail, a tightening moving unit, and a tightening unit. The top rail is fixedly connected to the fixed bracket. The tightening moving unit is connected to the top rail and is used to drive the tightening unit to move toward or away from the workpiece. The tightening unit is used to tighten the locking cap on the workpiece.
[0008] Furthermore, the clamping assembly includes a clamping cylinder, a mounting bracket, a clamping connecting rod, and a clamping block. The mounting bracket is fixedly connected to one side of the support 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 connecting rod, the middle section of the clamping connecting rod is rotatably connected to the mounting bracket, and the other end of the clamping connecting rod is connected to the clamping block.
[0009] When the workpiece to be processed does not enter the support platform, the clamping linkage flips outward relative to the support platform;
[0010] When the workpiece enters the support platform, the clamping link flips inward relative to the support platform, and the clamping block contacts the workpiece to press it firmly onto the support platform.
[0011] Furthermore, it also includes a transition tilting assembly, which includes a transition tilting cylinder, a transition tilting connecting rod, and a transition tilting plate. The transition tilting cylinder is connected to one end of the transition tilting connecting rod, and the other end of the transition tilting connecting rod is connected to the transition tilting plate. The transition tilting plate is hinged to the other side of the support platform relative to the clamping assembly.
[0012] When the workpiece to be processed has not entered the support platform, the transition flip plate is located on the same plane as the support platform;
[0013] When the workpiece moves from one side of the transition flip plate toward the support platform, the transition flip cylinder drives the transition flip plate to flip upward relative to the support platform and pushes the workpiece onto the support platform.
[0014] Furthermore, it also includes an ejection component, which is disposed on a side of the support platform perpendicular to the side where the clamping component is located;
[0015] The ejection assembly includes a push plate, a slide plate, a guide rod, and a rodless cylinder. The push plate is perpendicular to the support platform and is connected to the slide plate. The slide plate is arranged parallel to the support platform and located below the support platform. The guide rod is along the length of the support platform. The rodless cylinder drives the slide plate to slide along the guide rod. The push plate pushes the workpiece to be processed out of the support platform.
[0016] Furthermore, the slide plate is provided with a connector, which connects the slide plate and the push plate. The support platform includes multiple spaced support plates, and the connector is inserted into the gap between adjacent support plates.
[0017] Furthermore, it also includes a testing mechanism, which includes a testing bracket, a testing moving unit, and a testing head. The testing bracket is mounted on the support platform, and the testing moving unit is mounted on the testing bracket. The testing moving unit is used to drive the testing head to move, and the testing head is used to detect the resistance value on the workpiece to be processed.
[0018] Furthermore, the detection bracket includes two L-shaped rods, one horizontal rod, a first irregular leg, and a second irregular leg. One end of each of the two L-shaped rods is connected to both ends of the horizontal rod, and the other end of each of the two L-shaped rods is connected to one side of the support platform. One end of the first irregular leg is connected to one end of the horizontal rod, and the other end of the first irregular leg is connected to the opposite side of the support platform. One end of the second irregular leg is connected to the other end of the horizontal rod, and the other end of the second irregular leg is connected to the opposite side of the support platform.
[0019] Furthermore, it also 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 mounted on the flipping bracket, and the flipping motor is connected to the support platform.
[0020] Furthermore, it also includes a lifting mechanism, which includes a lifting motor mounted 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 causes the tilting bracket to rise upward;
[0022] When the lifting rod retracts downwards, it causes the tilting bracket to fall back onto the base.
[0023] Furthermore, the workpiece to be processed is a fuel tank and fuel pump, which is provided with a fuel inlet, and the locking cap is used to lock the fuel inlet.
[0024] The above technical solution has the following beneficial effects:

[0047] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0048] It is readily understood that, based on the technical solution of this invention, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of the invention.
[0049] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.
[0050] In some embodiments of the present invention, such as Figures 1-2 As shown, the processing device includes a tightening assembly 1, a base 2, a support platform 3, and a clamping assembly 4. The support platform 3 is installed above the base 2 and is used to place the workpiece 10 to be processed. The clamping assembly 4 is installed on the support platform 3 and is used to clamp the workpiece 10 to be processed on the support platform 3.
[0051] The tightening assembly 1 is located above the support platform 3. The tightening assembly 1 includes a fixed bracket 11, a top rail 12, a tightening moving unit 13, and a tightening unit 14. The top rail 12 is fixedly connected to the fixed bracket 11. The tightening moving unit 13 is connected to the top rail 12 and is used to drive the tightening unit 14 to move toward or away from the workpiece 10 to be processed. The tightening unit 14 is used to tighten the locking cover 101 on the workpiece 10 to be processed.
[0052] Specifically, such as Figure 1As shown, base 2 is located at the bottom and is fixed to the ground or workbench, providing support for the support platform 3 and clamping assembly 4 installed above. Base 2 includes two horizontal bars, four diagonal braces, and two vertical frame structures.
[0053] The support platform 3 is installed above the base 2, and the bearing surface of the support 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] When the workpiece 10 is placed on the support table 3, there are two sets of clamping components 4, which clamp the left and right parts of the workpiece 10 respectively, so that the workpiece 10 is pressed on the support table 3.
[0055] like Figure 2 As shown, the tightening assembly 1 is not connected to the base 2, and the tightening assembly 1 is suspended above the support platform 3. The tightening assembly 1 includes a fixed bracket 11, a ceiling track 12, a tightening moving unit 13, and a tightening unit 14.
[0056] The fixed bracket 11 includes two vertical frame structures, and the fixed bracket 11 is fixedly connected to the ceiling or the suspension above.
[0057] The ceiling track 12 is a rectangular frame structure along the horizontal plane, and the tightened moving unit 13 can slide back and forth along the ceiling track 12.
[0058] The tightening moving unit 13 includes an X-axis moving component 131, a Y-axis moving component 132, and a Z-axis moving component 133. The X-axis moving component 131 can slide back and forth along the ceiling track 12. The Y-axis moving component 132 can slide in the left and right direction relative to the X-axis moving component 131. The Z-axis moving component 133 is connected to the Y-axis moving component 132. The tightening unit 14 is connected to the Z-axis moving component 133 and can slide in the up and down direction relative to the Z-axis moving component 133. Therefore, the X-axis moving component 131, the Y-axis moving component 132, and the Z-axis moving component 133 can be used to adjust the tightening unit 14 in the up and down, left and right, and back and forth directions, moving the tightening unit 14 toward or away from the workpiece 10.
[0059] When it is necessary to tighten the locking cover 101 of the workpiece 10, the tightening moving unit 13 controls the tightening unit 14 to be inserted into the locking cover 101. Then, the tightening unit 14 drives the locking cover 101 to rotate, thereby tightening the locking cover 101.
[0060] Furthermore, such as Figure 2 As shown, the tightening unit 14 includes a servo motor 141, a fixed base 142, a detection switch 143, and a tightening disc 144.
[0061] The fixed base 142 is connected to the Z-axis moving component 133 and is capable of moving vertically relative to the Z-axis moving component 133. The servo motor 141, the detection switch 143, and the tightening disc 144 are all mounted on the fixed base 142. The servo motor 141 is used to drive the tightening disc 144 to rotate.
[0062] The tightening disc 144 has multiple protruding teeth. The tightening moving unit 13 drives the protruding 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, thereby tightening 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 is tightened in place, the detection switch 143 sends a signal to the servo motor 141, the servo motor 141 stops rotating, and the tightening moving unit 13 drives the tightening unit 14 to rise, so that the tightening disc 144 separates from the locking cover 101.
[0063] Preferably, the detection switch 143 is equipped with an audible and visual alarm.
[0064] Preferably, the tightening disc 144 is also equipped with a visual inspection mechanism at its tail end to take pictures of the locking cover 101, and the visual inspection mechanism is connected to the PLC control system.
[0065] Better, such as Figure 2 As shown, the tightening unit 14 also includes a positioning member 145, the tail end of which is provided with an elastic pin, and the positioning member 145 is located on the side of the tightening disc 144.
[0066] like Figure 1 As shown, the workpiece 10 to be processed is also provided with a positioning hole 102. When the positioning element 145 is inserted into the positioning hole 102, the tightening disc 144 is aligned with the locking cover 101. However, at this time, the protruding teeth of the tightening disc 144 may not yet be inserted into the locking cover 101. The rotation of the servo motor 141 drives the protruding teeth of the tightening disc 144 to align with the slots on the locking cover 101, so that the protruding teeth can be accurately inserted into the slots. Therefore, the positioning element 145 can achieve precise and rapid positioning of the tightening disc 144.
[0067] Furthermore, such as Figure 5 As shown, the clamping assembly 4 includes a clamping cylinder 41, a mounting bracket 42, a clamping connecting rod 43, and a clamping block 44. The mounting bracket 42 is fixedly connected to one side of the support 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 connecting rod 43. The middle section of the clamping connecting rod 43 is rotatably connected to the mounting bracket 42. The other end of the clamping connecting rod 43 is connected to the clamping block 44.
[0068] When the workpiece 10 does not enter the support table 3, the clamping link 43 flips outward relative to the support table 3;
[0069] When the workpiece 10 enters the support table 3, the clamping link 43 flips inward relative to the support table 3, and the clamping block 44 contacts the workpiece 10 and presses the workpiece 10 onto the support table 3.
[0070] Specifically, such as Figure 5 As shown, two sets of clamping components 4 are installed on the front side of the support table 3. The two sets of clamping components 4 move synchronously to achieve synchronous clamping or loosening of the workpiece 10 to be processed.
[0071] The clamping assembly 4 has a mounting bracket 42 fixedly connected to the support platform 3, and a clamping cylinder 41 fixedly mounted on the mounting bracket 42. The extended end of the telescopic rod of the clamping cylinder 41 is rotatably connected to one end of the clamping connecting rod 43. When the telescopic rod extends or retracts, it drives the clamping connecting rod 43 to swing. The middle section of the clamping connecting rod 43 is rotatably connected to the mounting bracket 42, and this connection point serves as the rotation center of the clamping connecting rod 43. The other end of the clamping connecting rod 43 is connected to a clamping block 44. The clamping connecting rod 43 extends the clamping block 44 toward the workpiece 10. When the clamping connecting rod 43 swings downward, the clamping block 44 contacts the workpiece 10, thus clamping the workpiece 10.
[0072] When the workpiece 10 is not placed on the support table 3, the telescopic rod of the clamping cylinder 41 retracts, causing the clamping connecting rod 43 to flip upward and outward, and the clamping block 44 to lift upward.
[0073] When the workpiece 10 enters the support table 3, the telescopic rod of the clamping cylinder 41 extends upward, causing the clamping connecting rod 43 to flip downward and inward, and the clamping block 44 presses down on the upper surface of the workpiece 10, thereby pressing the workpiece 10 onto the support table 3.
[0074] Preferably, the clamping block 44 is installed at an angle toward the workpiece 10 to facilitate clamping 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.
[0075] Furthermore, such as Figures 3-5 As shown, it also includes a transition tilting assembly 5, which includes a transition tilting cylinder 51, a transition tilting connecting rod 52 and a transition tilting plate 53. The transition tilting cylinder 51 is connected to one end of the transition tilting connecting rod 52, and the other end of the transition tilting connecting rod 52 is connected to the transition tilting plate 53. The transition tilting plate 53 is hinged to the other side of the support platform 3 relative to the clamping assembly 4.
[0076] When the workpiece 10 is not on the support table 3, the transition flip plate 53 and the support table 3 are on the same plane;
[0077] When the workpiece 10 moves from one side of the transition flip plate 53 toward the support platform 3, the transition flip cylinder 51 drives the transition flip plate 53 to flip upward relative to the support platform 3 and pushes the workpiece 10 onto the support platform 3.
[0078] Specifically, such as Figures 3-4 As shown, the transition flipping component 5 is disposed on the rear side of the support table 3. When the workpiece 10 is moved into the support table 3 from the rear side, the transition flipping component 5 flips in the opposite direction of the support table 3, pushing the workpiece 10 into the support table 3.
[0079] like Figure 5 As shown, the transition tilting assembly 5 includes a transition tilting cylinder 51, a transition tilting connecting rod 52, and a transition tilting plate 53. The transition tilting cylinder 51 is mounted on the side of the support platform 3. The extended end of the telescopic rod of the transition tilting cylinder 51 is rotatably connected to one end of the transition tilting connecting rod 52, and the other end of the transition tilting connecting rod 52 is rotatably connected to the transition tilting plate 53. The connection between the transition tilting connecting rod 52 and the transition tilting plate 53 is also hinged to the support platform 3.
[0080] Figure 5 The intermediate transition flip plate 53 and the support table 3 are on the same horizontal plane, and the workpiece 10 to be processed is translated from the direction of the transition flip plate 53 toward the support table 3.
[0081] When the workpiece 10 passes the transition flip plate 53, the telescopic rod of the transition flip cylinder 51 retracts downward, causing the transition flip connecting rod 52 to swing downward. The transition flip connecting rod 52 causes the transition flip plate 53 to flip upward, and the transition flip plate 53 pushes the workpiece 10 above the support table 3.
[0082] Furthermore, such as Figures 6-7 As shown, it also includes an ejection component 6, which is disposed on the side of the support platform 3 perpendicular to the side where the clamping component 4 is located.
[0083] The ejection assembly 6 includes a push plate 61, a slide plate 62, a guide rod 63, and a rodless cylinder 64. The push plate 61 is perpendicular to the support platform 3 and is connected to the slide plate 62. The slide plate 62 is arranged parallel to the support platform 3 and is located below the support platform 3. The guide rod 63 is along the length of the support platform 3. The rodless cylinder 64 drives the slide plate 62 to slide along the guide rod 63. The push plate 61 pushes the workpiece 10 to be processed out of the support platform 3.
[0084] Specifically, in this embodiment, the ejection component 6 is located on the right side of the support platform 3. The ejection component 6 is used to eject the workpiece 10 to be processed from the left side of the support platform 3, so as to facilitate the transfer of the workpiece 10 to the next processing station.
[0085] like Figure 7As shown, the ejector assembly 6 includes a push plate 61, a slide plate 62, a guide rod 63, and a rodless cylinder 64. The slide plate 62, guide rod 63, and rodless cylinder 64 are all located below the support platform 3, with the guide rod 63 and rodless cylinder 64 arranged along the left-right direction of the support platform 3. The slide plate 62 is installed between the two guide rods 63 and is mounted above the rodless cylinder 64. The push plate 61 is fixedly connected to the slide plate 62, and the push plate 61 is perpendicular to the support platform 3.
[0086] Figure 7 When component 6 is not in operation, push plate 61 is located on the right side of support platform 3.
[0087] When the workpiece 10 needs to be removed from the support platform 3, the rodless cylinder 64 drives the slide plate 62 to slide along the guide rod 63. The slide plate 62 slides from right to left, and the push plate 61 pushes the workpiece 10 out of the support platform 3 from right to left.
[0088] Furthermore, such as Figures 6-7 As shown, the slide plate 62 is provided with a connector 621, which connects the slide plate 62 and the push plate 61. The support platform 3 includes multiple spaced support plates 31, and the connector 621 is inserted into the gap between adjacent support plates 31.
[0089] Specifically, such as Figure 6 As shown, the support platform 3 includes three support plates 31, with gaps between adjacent support plates 31. The connector 621 protrudes through the gaps, making the connector 621 flush with the upper surface of the support plate 31. When the slide plate 62 drives the push plate 61 to slide, it will not interfere with the connector 621.
[0090] Furthermore, such as Figure 8 As shown, it also includes a detection mechanism 7, which includes a detection bracket 71, a detection moving unit 72, and a detection head 73. The detection bracket 71 is mounted on the support platform 3, and the detection moving unit 72 is mounted 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 to be processed.
[0091] After the workpiece 10 is clamped by the clamping assembly 4 and the locking cover 101 is tightened by the tightening assembly 1, the detection moving unit 72 drives the detection head 73 to move toward the workpiece 10. The detection head 73 is inserted into the electrical detection port of the workpiece 10 to detect the resistance value of the workpiece 10.
[0092] Preferably, the detection head 73 is equipped with an audible and visual alarm.
[0093] Furthermore, such as Figure 8As shown, the testing bracket 71 includes two L-shaped rods 711, a horizontal rod 712, a first irregular leg 713, and a second irregular leg 714. One end of each of the two L-shaped rods 711 is connected to both ends of the horizontal rod 712, and the other end of each of the two L-shaped rods 711 is connected to one side of the support platform 3. One end of the first irregular leg 713 is connected to one end of the horizontal rod 712, and the other end of the first irregular leg 713 is connected to the opposite side of the support platform 3. One end of the second irregular leg 714 is connected to the other end of the horizontal rod 712, and the other end of the second irregular leg 714 is connected to the opposite side of the support platform 3.
[0094] Specifically, the L-shaped rod 711 is connected to the front side of the support platform 3, and the transverse rod 712 is located above the rear side of the support platform 3. A space is left between the transverse rod 712 and the support platform 3 for the workpiece 10 to be processed to enter the support platform 3.
[0095] The first irregular leg 713 is connected to the left side of the support platform 3, and the second irregular leg 714 is connected to the right side of the support platform 3. Since there are oil pipes connected to the workpiece 10 to be processed, in order to avoid interference with the oil pipes, the first irregular leg 713 and the second irregular leg 714 are designed as irregular rod structures.
[0096] Better, such as Figure 8 As shown, the detection movement unit 72 includes an X-axis detection movement component 721, a Y-axis detection movement component 722, and a Z-axis detection movement component 723. The X-axis detection movement component 721 is mounted on an L-shaped rod 711, the Y-axis detection movement component 722 is mounted on a horizontal rod 712, the Z-axis detection movement component 723 is mounted on the Y-axis detection movement component 722, and the detection head 73 is mounted on the Z-axis detection movement component 723. The detection head 73 moves vertically relative to the Z-axis detection movement component 723, the Z-axis detection movement component 723 moves horizontally relative to the Y-axis detection movement component 722, and the Y-axis detection movement component 722 moves forward and backward relative to the X-axis detection movement component 721. This allows for the movement adjustment of the detection head 73 in the X, Y, and Z directions, enabling precise targeting of the electrical inspection port of the workpiece 10.
[0097] Furthermore, such as Figure 9 As shown, it also includes a flipping mechanism 8, which 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 mounted on the flipping bracket 82, and the flipping motor 81 is connected to the support platform 3.
[0098] Specifically, two flipping brackets 82 are respectively mounted on the left and right ends of the base 2, and a flipping motor 81 is connected to one of the flipping brackets 82. The drive shaft of the flipping motor 81 is connected to the support platform 3, and when the flipping motor 81 is driven, it causes the support platform 3 to flip. The other flipping bracket 82 is rotatably connected to the other side of the support platform 3 through a bearing.
[0099] After the inspection mechanism 7 inspects the workpiece 10, the flipping mechanism 8 rotates the workpiece 10 180°, and the inspection head 73 inspects the workpiece 10 again. After the inspection is completed, the flipping mechanism 8 rotates the workpiece 10 back to its original position.
[0100] When the support platform 3 is flipped, the clamping assembly 4, the transition flipping assembly 5, the ejection assembly 6 and the detection mechanism 7 installed on the support platform 3 flip together.
[0101] Furthermore, such as Figure 9 As shown, it also includes a lifting mechanism 9, which includes a lifting motor 91. The lifting motor 91 is mounted on the base 2, and 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 tilting bracket 82 to rise upward;
[0103] When the lifting rod 92 retracts downward, it drives the tilting bracket 82 to fall back onto the base 2.
[0104] Specifically, the lifting mechanism 9 includes two sets, 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, and the lifting rod 92 passes vertically through the base 2 and is connected to the bottom of the tilting bracket 82.
[0105] When the lifting mechanism 9 retracts, the flipping bracket 82 contacts the base 2, and the base 2 provides support 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 separates from the base 2.
[0107] Then, the flipping mechanism 8 drives the carrier platform 3 to flip, the detection mechanism 7 performs the detection, and after the detection is completed, the flipping mechanism 8 flips back to its original position, and the lifting mechanism 9 drives the flipping bracket 82 to descend back to the base 2.
[0108] In this embodiment, the workpiece 10 to be processed is a fuel tank / fuel pump, which has a fuel filler port. The locking cap 101 is used to lock the fuel filler port. Optionally, the workpiece 10 to be processed can also be a workpiece that requires tightening and inspection.
[0109] In a preferred embodiment of the present invention, the operation of the processing device is as follows:
[0110] The workpiece 10 is first fed into the transition flipping assembly 5, which pushes the workpiece 10 into the support table 3. Then, the clamping assembly 4 presses the workpiece 10 onto the support 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. The tightening moving unit 13 drives the tightening unit 14 to move according to the parameters of the workpiece 10 to be processed.
[0112] After the tightening unit 14 moves close to the locking cover 101, the positioning component 145 is first inserted into the positioning hole 102 of the workpiece 10 to achieve precise positioning. 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, which rotates the tightening disc 144 clockwise. When the detection switch 143 detects that the torque of the tightening disc 144 has reached the set range, the Z-axis moving component 133 drives the tightening unit 14 back to the standby position, and the tightening operation ends. When the detection switch 143 detects that the torque has not reached the set range, the system issues an alarm and stops working. The operator confirms the quality and checks the cause of the alarm, and performs manual tightening. After checking that the tightening is complete, the Z-axis moving component 133 drives the tightening unit 14 back to the standby position. At this time, the system activates the vision inspection mechanism to visually photograph and confirm the installation angle of the locking cover 101, and transmits the data to the host computer for storage.
[0113] When the system detects that the Z-axis moving component 133 has reached the standby position, the detection mechanism 7 begins to operate. The detection moving unit 72 moves the detection head 73 according to the vehicle model information, and after positioning, moves the detection head 73 vertically downwards. When the system detects that the detection head 73 has been inserted into the electrical inspection port of the workpiece 10, the control system issues a 0° position detection start command to detect the real-time sliding resistance value of the fuel pump. When the detected resistance value exceeds the set range, the system stops operating and issues an audible and visual alarm to prompt the operator to manually confirm the issue. The operator then replaces the fuel pump and re-detects the problem.
[0114] After the resistance value is detected within the process setting range, the lifting mechanism 9 raises the tilting mechanism 8 and the support platform 3. Once the lifting is complete, the tilting mechanism 8 tilts the entire detection mechanism 7, the workpiece 10, and the support platform 3 180°. The system detects that the workpiece 10 is in the correct position and sends a command to the control system. The detection mechanism 7 then detects the resistance value of the workpiece 10 at the 180° position. Similarly, if the detected real-time value is within the set range, the tilting mechanism 8 returns to its original position; otherwise, an audible and visual alarm is triggered. After the tilting mechanism 8 returns to its original position, the lifting mechanism 9 returns to its original position, and the detection movement unit 72 pulls the detection head 73 out of the electrical detection port. After the system confirms that all detections are in place, it opens the clamping assembly 4 and pushes out the push assembly 6, pushing the workpiece 10 out of the support platform 3, completing a full workflow.
[0115] This invention enables automatic tightening of the locking cap, reducing the inconvenience caused by manual operation. Simultaneously, it can detect the resistance value of the workpiece 10, avoiding the inefficiency and poor quality caused by mixing fuel tanks from different vehicle models. This invention integrates the tightening and testing functions of the fuel tank and fuel pump into one unit, improving work efficiency and assembly quality.
[0116] The above description is merely the principle and preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several other modifications can be made based on the principle of the present invention, and these modifications should also be considered within the scope of protection of the present invention.
