Detailed Implementation

[0018] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0019] In the description of this invention, it should be understood that the term "**" is used herein. like Figure 1 As shown, the automatic fuel injector installation device of this embodiment includes: a feeding mechanism, a transfer mechanism, and a locking mechanism; the feeding mechanism includes a sorting module 130, a bolt feeding module 110, and two fuel injector feeding modules 120, which are respectively disposed on both sides of the bolt feeding module 110. The sorting module 130 is disposed above the bolt feeding module 110 and the fuel injector feeding modules 120, and the sorting module 130 can clamp bolts from the bolt feeding module 110. Block 130 can pick up fuel injectors from fuel injector loading module 120; the transfer mechanism includes transfer fixture 210 and transfer module 220, the sorting module 130 loads bolts and fuel injectors onto transfer fixture 210, and the transfer module 220 is used to install bolts and fuel injectors from transfer fixture 210 onto cylinder block; the locking mechanism includes positioning device 320 and tightening module 310, the positioning device 320 is used to position cylinder block, and the tightening module 310 is used to tighten bolts to lock fuel injectors onto cylinder block.

[0020] The bolt feeding module 110 automatically feeds out bolts one by one. Two fuel injector feeding modules 120 are used for single-pipe fuel injector feeding and double-pipe fuel injector feeding, respectively. After the sorting module 130 picks up the bolt from the bolt feeding module 110, it takes out the single-pipe fuel injector and places the single-pipe fuel injector and bolt on the transfer fixture 210. Then it picks up the bolt and double-pipe fuel injector and puts them on the transfer fixture 210. The transfer fixture 210 is then sent to the transfer mechanism. The transfer mechanism installs the single-pipe fuel injector and double-pipe fuel injector on the transfer fixture 210 onto the cylinder of the positioning device 320. Then the bolt is initially installed on the cylinder. Finally, the bolt is tightened by the tightening module 310, locking the fuel injector onto the cylinder. This achieves automated fuel injector installation, ensures installation quality, and improves production efficiency.

[0021] Understandably, referring to Figure 1 and Figure 2 The bolt feeding module 110 includes a vibratory feeder 111 and a conveyor chute 112. One end of the conveyor chute 112 is connected to the discharge end of the vibratory feeder 111, and the other end of the conveyor chute 112 is close to the transfer clamp 210. A lifting device is provided at the other end of the conveyor chute 112 to raise the bolts. The vibratory feeder 111 feeds the bolts one by one to the conveyor chute 112, and the bolts are then sent out one by one, making it convenient for the sorting module 130 to grab them one by one. At the same time, when the bolts are conveyed to the lifting device, the lifting device raises the bolts, making the bolts protrude from the conveyor chute 112, making it easier for the sorting module 130 to grab the bolts, further improving the success rate of the sorting module 130 in grabbing the bolts.

[0022] Specifically, it can be understood that, referring to Figure 1 and Figure 2 The lifting device includes a first limiting block 1131, a first pressure plate 1135, and a first lifting assembly. The first limiting block 1131 is disposed at the end of the conveying slide 112. The first limiting block 1131 and the end of the conveying slide 112 cooperate to form a through hole 1132. The through hole 1132 matches the bolt. The moving end of the first lifting assembly passes through the through hole 1132 and cooperates with the first pressure plate 1135 to clamp and lift the bolt. The bolt is sent from the vibrating plate 111 to the conveying slide 112. The bolt falls into the through hole 1132 with the screw head facing upward. Then, the first pressure plate 1135 presses down to hold the bolt in place. Then, in conjunction with the first lifting assembly, the bolt is steadily lifted to avoid jamming or tipping during the lifting process, ensuring production stability. Then, the first pressure plate 1135 is moved away, and the sorting module 130 removes the bolt.

[0023] Understandably, referring to Figure 1 and Figure 2The first pressure plate 1135 component includes a first motor, a first cylinder 1133, a first connecting plate 1134, and a first pressure plate 1135. The first motor drives the first cylinder 1133 to rotate horizontally, and the first cylinder 1133 drives the first connecting plate 1134 to move vertically. The first pressure plate 1135 is positioned on the first connecting plate 1134. The first pressure plate 1135, in conjunction with the first lifting assembly, clamps the bolt and raises it. The first motor drives the first connecting plate 1134 to rotate, positioning the first pressure plate 1135 above the bolt. Then, the first cylinder 1133 activates, driving the first pressure plate 1135 to descend. The first pressure plate 1135 presses down on the bolt, moving synchronously with the first lifting assembly to ensure the bolt rises stably.

[0024] Additionally, refer to Figure 2 The first connecting plate 1134 is provided with a third guide post 1136. One end of the third guide post 1136 is connected to the first pressure plate 1135, and the other end of the third guide post 1136 is slidably connected to the first connecting plate 1134. A third spring 1137 is sleeved on the third guide post 1136. The third spring 1137 is located between the first connecting plate 1134 and the first pressure plate 1135. The first cylinder 1133 drives the first pressure plate 1135 to descend. After the first pressure plate 1135 presses down on the bolt, the first pressure plate 1135 drives the third guide post 1136 to slide upward. The first pressure plate 1135 compresses the third spring 1137, so that the third spring 1137 drives the first pressure plate 1135 to keep in contact with the bolt, thereby improving the fault tolerance rate of the cooperation between the first pressure plate 1135 and the first lifting assembly and enhancing the stability when the bolt is raised.

[0025] Understandably, referring to Figure 2 The first lifting assembly includes a movable shaft 1138 and a second cylinder. The second cylinder drives the movable shaft 1138 through a through hole 1132. The movable shaft 1138 cooperates with the first pressure plate 1135 to raise the bolt, so that the bolt protrudes from the conveying slide 112. The movable shaft 1138 is driven by the second cylinder to move vertically, and the movable shaft 1138 raises the bolt by passing through the through hole 1132. The end of the movable shaft 1138 has a mating hole that matches the bolt. After the bolt falls vertically into the through hole 1132, it is inserted into the mating hole. When the movable shaft 1138 raises the bolt, it can reduce the risk of the bolt falling.

[0026] Understandably, referring to Figure 1 and Figure 4The fuel injector feeding module 120 includes a first support plate 1241, a second support plate 1242, a sliding assembly 121, a second lifting assembly, and a conveying assembly. The second support plate 1242 is disposed above the first support plate 1241, and the sliding assembly 121 is disposed on the first support plate 1241. The moving end of the sliding assembly 121 is used to load and stack the material tray 410. The sliding device slides the material tray 410 to the second lifting assembly. The second lifting assembly drives the material tray 410 to rise and pass through the second support plate 1242 so that the sorting module 130 can pick up the fuel injectors. The conveying assembly transports the empty material tray 410 from the sliding assembly 121 to the second support plate 1242. The fuel injectors are evenly placed in the material trays 410. Multiple material trays 410 are stacked on the sliding assembly 121. Then, the second lifting assembly raises the stacked material trays 410, so that the top material tray 410 protrudes from the second support plate 1242, making it easier for the sorting module 130 to pick up the fuel injectors. After all the fuel injectors in the material trays 410 have been taken, the conveying assembly removes the empty material trays 410 and places them in the collection position 1243 of the second support plate 1242. Then, the second lifting assembly continues to rise, raising the next material tray 410 so that it protrudes from the second support plate 1242, achieving continuous feeding, reducing the number of material replenishments, and improving production efficiency.

[0027] Understandably, referring to Figure 4 The sliding assembly 121 includes a first linear slide module 1211 and a first support plate 1212. The first support plate 1212 is located at the moving end of the first linear slide module 1211. Multiple first support rods 1213 are provided along the edge of the first support plate 1212, forming a stacking rack around it. Multiple trays 410 equipped with fuel injectors are placed on the first support plate 1212. The first support rods 1213 can position the stacked trays 410, preventing them from shaking or tipping over, thus ensuring stability when the second lifting assembly drives the trays 410 to rise.

[0028] Understandably, referring to Figure 4The second lifting assembly includes a second linear slide module 1221 and a second support plate. The first support plate 1212 has a first clearance opening 1214, and the second support plate 1242 has a second clearance opening 1244. The second linear slide module 1221 drives the second support plate to pass through the first clearance opening 1214 and the second clearance opening 1244 in sequence. By opening the first clearance opening 1214, when the second linear slide module 1221 drives the second support plate to rise, it passes through the first clearance opening 1214 to lift the stacked trays 410. During the lifting process, the first retaining rod 1213 on the first support plate 1212 limits the stacked trays 410, keeping the stacked trays 410 stable. When the uppermost tray 410 passes through the second clearance opening 1244, the second linear slide module 1221 stops moving.

[0029] Understandably, referring to Figure 4 The conveying assembly includes a third linear slide module 1231, a fourth linear slide module 1232, and a suction cup 1233. The third linear slide module 1231 drives the suction cup 1233 to move horizontally, and the fourth linear slide module 1232 drives the suction cup 1233 to move vertically. When the fuel injectors in the tray 410 are depleted, the third linear slide module 1231 drives the suction cup 1233 to move above the second pallet. Then, the fourth linear slide module 1232 drives the suction cup 1233 to descend, and the suction cup 1233 picks up the tray 410. Then, the fourth linear slide module 1232 rises, and the third linear slide module 1231 transports the suction cup 1233 to above the collection position 1243. Then, the fourth linear slide module 1232 descends, and the suction cup 1233 releases the tray 410, placing the tray 410 in 348, thus realizing the recycling of the tray 410.

[0030] Understandably, referring to Figure 1 and Figure 5The sorting module 130 includes a drive assembly and a sorting fixture 134. The drive assembly includes a second motor 136, a fifth linear slide module 131, a sixth linear slide module 132, and a seventh linear slide module 133. The second motor 136 drives the sorting module 130 to rotate in the horizontal plane. The fifth linear slide module 131 drives the sorting fixture 134 to move along a first direction. The sixth linear slide module 132 drives the sorting fixture 134 to move along a second direction. The seventh linear slide module 133 drives the sorting fixture 134 to move along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. Both the first and second directions are horizontal. The fifth linear slide module 131 and the sixth linear slide module 132 drive the sorting fixture 134 to move back and forth between the bolt feeding module 110 and the two fuel injector feeding modules 120, thus removing the fuel injectors one by one from the material tray 410. The fifth linear slide module 131 and the sixth linear slide module 132 work together to drive the sorting fixture 134 to the bolt feeding module 110. The seventh linear slide module 133 drives the sorting fixture 134 to descend and clamp the bolts, completing the bolt removal process. Then, the fifth linear slide module 131 and the sixth linear slide module 132 work together to drive the sorting fixture 134 to the fuel injector feeding module 120. The second motor 136 drives the sorting fixture 134 to rotate, so that the part of the sorting fixture 134 used to pick up the fuel injector is directly facing the fuel injector. Through the cooperation of the second motor 136, the fifth linear slide module 131, the sixth linear slide module 132 and the seventh linear slide module 133, the bolt and the fuel injector can be picked up with a single sorting fixture 134, simplifying the structure and saving space.

[0031] Understandably, referring to Figure 5 The sorting fixture 134 includes a first support 1341, a bolt gripping assembly, and a fuel injector suction assembly. Both the bolt gripping assembly and the fuel injector suction assembly are mounted on the first support 1341. The bolt gripping assembly is used to remove bolts from the bolt feeding module 110, and the fuel injector suction assembly is used to remove fuel injectors from the fuel injector feeding module 120. The bolt gripping assembly and the fuel injector suction assembly are integrated on the first support 1341, reducing the hardware cost and space occupied by the equipment. Furthermore, the bolt gripping assembly and the fuel injector suction assembly share the second motor 136, the fifth linear slide module 131, the sixth linear slide module 132, and the seventh linear slide module 133, reducing the cumulative error caused by multi-axis conversion and ensuring the accuracy of the relative position of the bolt and the fuel injector after being gripped, which is beneficial for the accurate loading of the subsequent transfer fixture 210.

[0032] Understandably, referring to Figure 6The bolt clamping assembly includes an eighth linear slide module 1348 and multiple gripper cylinders 1344. A second connecting plate 1349 is provided at the moving end of the eighth linear slide module 1348, and the multiple gripper cylinders 1344 are all mounted on the second connecting plate 1349. The eighth linear slide module 1348 drives the second connecting plate 1349 to move vertically. When the sorting fixture 134 moves to the bolt feeding module 110, the eighth linear slide module 1348 drives the gripper cylinders 1344 to descend, gripping the bolt head. Then, the eighth linear slide module 1348 drives the gripper cylinders 1344 to rise, pulling the bolt out of the conveyor slide 112. The multiple gripper cylinders 1344 can grip multiple bolts simultaneously, improving clamping efficiency.

[0033] Understandably, referring to Figure 5 The fuel injector suction assembly includes a ninth linear slide module 1342, a movable block 1343, and multiple extraction components. The ninth linear slide module 1342 drives the movable block 1343 to move horizontally. The multiple extraction components are rotatably mounted on a first bracket 1341, and the movable block 1343 drives the extraction components to rotate. Each cylinder chamber of the cylinder block is equipped with one single-pipe fuel injector and one double-pipe fuel injector, and the installation angle between the single-pipe and double-pipe fuel injectors will be different depending on the engine displacement. By driving the movable block to rotate through the ninth linear slide module 1342, the extraction components pick up the fuel injectors, thereby adjusting the installation angle of multiple fuel injectors.

[0034] Specifically, it can be understood that, referring to Figure 5 The extraction component includes a second support 1346, a third cylinder 1347, and a first magnetic head 1354. The second support 1346 is rotatably mounted on the first support 1341, the third cylinder 1347 is mounted on the second support 1346, and the first magnetic head 1354 is slidably mounted on the second support 1346. The third cylinder 1347 drives the first magnetic head 1354 to move in the vertical direction. The second bracket 1346 is equipped with a rotatable gear 1345. A movable block 1343 is slidably mounted on the first bracket 1341. The movable block 1343 has a rack, which meshes with the gear 1345. When the ninth linear slide module 1342 drives the movable block 1343 to move horizontally, the rack drives the gear 1345 to rotate, thereby rotating the second bracket 1346. The second bracket 1346 drives the first magnetic head 1354 to rotate. By controlling the movement stroke of the rack, the rotation angle of the second bracket 1346 can be controlled, achieving precise installation angle adjustment. The third cylinder 1347 drives the first magnetic head 1354 to descend, contacting the fuel injector and holding it in place, thus enabling simple and effective removal of the fuel injector.

[0035] Understandably, referring to Figure 5The second support 1346 is equipped with a first guide post 1353 and a first slider 1351. The first slider 1351 and the first magnetic head 1354 are slidably connected to the first guide post 1353. The third cylinder 1347 drives the first slider 1351 to move. The first guide post 1353 is sleeved with a first spring 1352, which is located between the first slider 1351 and the first magnetic head 1354. After the seventh linear slide module 133 drives the first magnetic head 1354 to descend, the third cylinder 1347 drives the first slider 1351 to move downward. The first slider 1351 transmits the thrust to the first magnetic head 1354 through the first spring 1352. When the first magnetic head 1354 moves downward and stops when it comes into contact with the fuel injector, the third cylinder 1347 continues to extend, the first slider 1351 continues to move along the guide post and compresses the first spring 1352, generating a buffer displacement, and at the same time making the first magnetic head 1354 stick to the fuel injector, improving the success rate of picking up the fuel injector.

[0036] Furthermore, it is understandable that, referring to Figure 5 The first slider 1351 is provided with a slide rod 1355, which can pass through the first magnetic head 1354. When the sorting fixture 134 places the fuel injector into the transfer fixture 210, the seventh linear slide module 133 cooperates with the third cylinder 1347 to increase the stroke of the first magnetic head 1354, so that the slide rod 1355 passes through the first magnetic head 1354 and abuts against the fuel injector, pressing the fuel injector onto the transfer fixture 210. When the first magnetic head 1354 is raised, the success rate of separation between the first magnetic head 1354 and the fuel injector is improved.

[0037] Understandably, referring to Figure 1 and Figure 7 The transfer fixture 210 includes a tenth linear slide module 211, a third support 213, and multiple pitch-changing devices 212. All pitch-changing devices 212 are mounted on the third support 213. The tenth linear slide module 211 drives the third support 213 to move horizontally, causing it to reciprocate between the feeding mechanism and the tightening mechanism. The pitch-changing devices 212 are used to evenly space the multiple fuel injectors. The fuel injectors and bolts are installed onto the pitch-changing devices 212, which enlarge adjacent fuel injectors to accommodate their mounting positions on the cylinder block. Then, the tenth linear slide module 211 drives the transfer fixture 210 closer to the tightening module 310, facilitating the transfer module 220 to directly install the fuel injectors and bolts from the transfer fixture 210 onto the cylinder block. By pre-changing the distance between the fuel injectors through the pitch-changing devices 212, the transfer mechanism can quickly and directly install the fuel injectors and bolts onto the cylinder block.

[0038] Understandably, referring to Figure 7The pitch-changing device 212 includes a first slide rail 2121 and at least two pitch-changing components. Each pitch-changing component includes two first positioning blocks 2123 and a fourth cylinder 2122. One first positioning block 2123 is fixed to the first slide rail 2121, and the other first positioning block 2123 is slidably disposed on the first slide rail 2121. The fourth cylinder 2122 drives the other first positioning block 2123 to move, causing the two first positioning blocks 2123 to move closer or further apart. Fuel injectors and bolts are installed onto the first positioning blocks 2123. The fourth cylinder 2122 drives one of the first positioning blocks 2123 to slide along the first slide rail 2121, causing the two first positioning blocks 2123 to move further apart, changing the distance between the two fuel injectors and aligning the fuel injector mounting positions on the cylinder block.

[0039] Understandably, referring to Figure 7 The first positioning block 2123 is equipped with two air pipes 2124 and two insertion holes 2125. These holes are used for insertion and engagement with the fuel injector and bolt, respectively. Any air pipe 2124 can be connected to any insertion hole 2125. The fuel injector and bolt are initially positioned by inserting them into the two insertion holes 2125. Then, the air pipes 2124 are connected to an air extraction device. Air is drawn out by the extraction device, creating a negative pressure within the insertion holes 2125, which in turn attracts the fuel injector and bolt, further positioning them and preventing them from falling off during movement.

[0040] Understandably, referring to Figure 1 and Figure 8 The transfer module 220 includes a fourth support 222, an eleventh linear slide module 221, and a material handling component 223. The eleventh linear slide module 221 drives the fourth support 222 to move, causing the material handling component 223 to reciprocate between the transfer fixture 210 and the positioning device 320. The material handling component 223 is mounted on the fourth support 222 and is used to install the fuel injector and bolts onto the cylinder block. The eleventh linear slide module 221 drives the fourth support 222 to move horizontally, enabling the material handling component 223 to reciprocate between the transfer fixture 210 and the positioning device 320.

[0041] Understandably, referring to Figure 8The material handling assembly 223 includes a third motor 2231, a fifth support 2232, and two sets of extraction components. The two extraction components are symmetrically arranged on the fifth support 2232, which is rotatably mounted on a fourth support 222. The third motor 2231 drives the fifth support 2232 to rotate, which in turn drives the extraction components to rotate. By setting two sets of extraction components, the number of nozzles and bolts retrieved from the transfer fixture 210 each time is increased, while the number of times the extraction components travel back and forth between the transfer fixture 210 and the positioning device 320 is reduced, thus improving production efficiency. The two sets of extraction components are symmetrically arranged, and the third motor 2231 drives the fifth support 2232 to rotate, allowing the two sets of extraction components to be used alternately.

[0042] Understandably, referring to Figure 8 The extraction component includes a twelfth linear slide module 2235, a third connecting plate 2233, and multiple second magnetic heads 2234. The twelfth linear slide module 2235 drives the third connecting plate 2233 to move vertically. The multiple second magnetic heads 2234 are evenly arranged horizontally on the third connecting plate 2233. The second magnetic heads 2234 are used to pick up the fuel injector and bolt. The twelfth linear slide module 2235 drives the third connecting plate 2233 to descend, so that the second magnetic heads 2234 contact the fuel injector and bolt. The second magnetic heads 2234 pick up the fuel injector and bolt and remove them from the transfer fixture 210.

[0043] Understandably, referring to Figure 8 The third connecting plate 2233 is provided with a buffer assembly, which includes a second slide rail 2241, a positioning plate 2245, a second slider 2242, and a second spring 2243. The second slide rail 2241 is vertically arranged, and the positioning plate 2245 is fixedly arranged on the third connecting plate 2233. A second guide post 2244 is provided on the positioning plate 2245. The second slider 2242 is sleeved with the second guide post 2244, and the second slider 2242 is slidably connected with the second slide rail 2241. The second spring 2243 is sleeved on the second guide post 2244 and is located between the second slider 2242 and the positioning plate 2245. The second magnetic head 2234 is arranged on the second slider 2242. When the third connecting plate 2233 descends, the second magnetic head 2234 contacts the fuel injector and bolt. The twelfth linear slide module 2235 continues to drive the second magnetic head 2234 to descend. The second slider 2242 moves along the second slide rail 2241 and compresses the second spring 2243. The counterforce of the second spring 2243 drives the second slider 2242, making the second magnetic head 2234 stick tightly to the fuel injector and bolt, thus increasing the success rate of the second magnetic head 2234 in adsorbing the fuel injector and bolt.

[0044] Understandably, referring to Figure 1 and Figure 9The tightening module 310 includes a thirteenth linear slide module 311, a connecting frame 314, a fourteenth linear slide module 313, and a tightening assembly. The thirteenth linear slide module 311 drives the connecting frame 314 to move horizontally. The fourteenth linear slide module 313 is mounted on the connecting frame 314 and drives the tightening assembly to move vertically. The thirteenth linear slide module 311 includes two linear slide modules. One linear slide module drives the connecting frame 314 to move in a first direction, and the other linear slide module drives the connecting frame 314 to move in a second direction. Together with the fourteenth linear slide module 313, the tightening assembly can be flexibly aligned with various mounting positions on the cylinder block.

[0045] Understandably, referring to Figure 1 and Figure 9 The tightening assembly includes a fourth motor 3121, a sleeve 3122, and a tightening tool 3123. The fourth motor 3121 is equipped with a drive shaft 3126, which drives the drive shaft 3126 to rotate. The drive shaft 3126 engages with the sleeve 3122, enabling the drive shaft 3126 to drive the sleeve 3122 to rotate. The sleeve 3122 then drives the tightening tool 3123 to rotate. The drive shaft 3126 is sleeved with the sleeve 3122, and the sleeve 3122 is connected to the moving end of the fourteenth linear slide module 313. The fourth motor 3121 drives the drive shaft to rotate. The end of the drive shaft 3126 that connects with the sleeve 3122 has a square cross-section. The inner side of the sleeve 3122 matches the connecting end of the drive shaft 3126, allowing the drive shaft 3126 to drive the sleeve 3122 to rotate. This, in turn, drives the tightening tool 3123 to rotate, and the tightening tool 3123 tightens the bolt onto the cylinder. Meanwhile, the sleeve 3122 is connected to the tightening tool 3123, which makes it convenient and quick to change the corresponding tightening tool 3123 according to different bolt specifications.

[0046] Understandably, referring to Figure 9 The fourth motor 3121 is equipped with a torque sensor 3127, which connects the fourth motor 3121 to the drive shaft 3126. The torque sensor 3127 detects the torque applied to the bolts by the fourth motor 3121, ensuring that the tightening degree of each bolt is consistent, while preventing loosening due to insufficient tightening, thus ensuring quality and improving safety performance.

[0047] Understandably, referring to Figure 9The tightening assembly also includes a fourth connecting plate 3125 and a fourth spring 3124. The fourth connecting plate 3125 is connected to both the sleeve 3122 and the moving end of the fourteenth linear slide module 313. The fourth spring 3124 is sleeved on the drive shaft 3126 and is located between the connecting frame 314 and the fourth connecting plate 3125. The fourteenth linear slide module 313 drives the fourth connecting plate 3125 to descend. The fourth connecting plate 3125 drives the sleeve 3122 to move downward, causing the tightening tool 3123 to descend and engage with the bolt. After the tightening tool 3123 engages with the bolt, the fourteenth linear slide module 313 continues to descend. The tightening tool 3123 is pushed by the force back to push the sleeve 3122 to slide along the drive shaft 3126, compressing the fourth spring 3124. After the fourth spring 3124 is compressed, its elastic force reacts to the sleeve 3122, making the tightening tool 3123 close to the bolt. This ensures that the tightening tool 3123 is in contact with the bolt, ensuring that the bolt is evenly stressed and that the torque of the fourth motor 3121 is stably transmitted to the bolt, avoiding the risk of bolt failure.

[0048] It should be noted that before production, the cylinder body is transported to the production line, and the position of the tightening component is preset and adjusted according to the threaded hole on the cylinder body so that the tightening tool 3123 is aligned with the bolt when it falls. In this embodiment, the tightening tool 3123 is an external hexagonal key. In the initial stage of the connection between the tightening tool 3123 and the bolt, if the tightening tool 3123 is not inserted into the internal hexagonal hole of the bolt, it will be pressed into the internal hexagonal hole by the pressure applied by the fourth spring 3124 during the rotation of the tightening tool 3123. The torque sensor 3127 ensures that the bolt is tightened to the set torque before the fourth motor 3121 stops rotating, ensuring that the bolt is tightened.

[0049] Understandably, referring to Figure 1The positioning device 320 includes a transport vehicle 322, a clamping assembly 323, a conveying track 321, and a push-pull assembly 324. The clamping assembly 323 is disposed above the conveying track 321. The transport vehicle 322 moves along the conveying track 321. The conveying track 321 is provided with a limiting component, which is used to position the transport vehicle 322 in the horizontal direction. The clamping assembly 323 is used to position the transport vehicle 322 in the vertical direction. The push-pull assembly 324 is used to pull the transport vehicle 322 into the conveying track 321 or push the transport vehicle 322 out of the conveying track 321. The cylinder is placed on the transport vehicle 322. The push-pull assembly 324 pulls the transport vehicle 322 into the conveying track 321. The push-pull assembly 324 pulls the transport vehicle 322 to the tightening position on the conveying track 321. The limiting component is activated, positioning the transport vehicle 322 along the conveying direction. At the same time, the push-pull assembly 324 resets, and the clamping assembly 323 clamps the cylinder, positioning the cylinder in the vertical direction, improving the stability of the cylinder when tightening the bolts. After tightening the bolts, the limiting component releases the transport vehicle 322, the clamping assembly 323 resets, and the push-pull assembly 324 is activated. At the same time, the transport vehicle 322 with the bolts tightened is pushed out, and the transport vehicle 322 with the bolts to be tightened is pulled to the tightening position, so that feeding and discharging are carried out simultaneously, improving production efficiency.

[0050] Understandably, referring to Figure 1 The transport vehicle 322 includes a base plate 3221, on which a plurality of second positioning blocks 3222 are provided. The plurality of second positioning blocks 3222 form a limit, which matches the outer contour shape of the cylinder. When the cylinder is placed on the base plate 3221, the plurality of second positioning blocks 3222 are in contact with the cylinder to ensure the stability of the cylinder.

[0051] Understandably, referring to Figure 1 The clamping assembly 323 includes a fifteenth linear slide module 3232 and a second pressure plate 3231. The fifteenth linear slide module 3232 drives the second pressure plate 3231 to move vertically. The fifteenth linear slide module 3232 also drives the second pressure plate 3231 to move downward, causing the second pressure plate 3231 to press the cylinder body onto the transport vehicle 322.

[0052] Understandably, referring to Figure 1 The limiting component 325 includes a second limiting block 3251 and a fifth cylinder. When the transport vehicle 322 is delivered into the conveying track 321, the fifth cylinder drives the second limiting block 3251 to rise. The transport vehicle 322 contacts the second limiting block 3251, thereby limiting the travel of the transport vehicle 322 and improving the positioning accuracy of the transport vehicle 322.

[0053] Understandably, referring to Figure 1The push-pull assembly 324 includes a sixteenth linear slide module 3245 and two hooks. The two hooks are spaced apart on the moving end of the sixteenth linear slide module 3245. The sixteenth linear slide module 3245 drives the two hooks to reciprocate horizontally to pull or push the transport vehicle 322. The sixteenth linear slide module 3245 drives the two hooks to move, one hook hooks the transport vehicle 322 to enter the conveying track 321, and the other hook pushes the transport vehicle 322 out of the conveying track 321, realizing simultaneous feeding and discharging, and improving production efficiency.

[0054] Specifically, it can be understood that, referring to Figure 3 The hook includes a pull rod 3241 and a hook body 3242. The hook body 3242 is located at one end of the pull rod 3241. An angle body 3243 is hinged to the hook body 3242. One end of the angle body 3243 abuts against the hook body 3242, and a gap is left between the other end of the angle body 3243 and the hook 3242. The angle body 3243 is provided with a guide slope 3244. When the sixteenth linear slide module 3245 is started, the angle body 3243 contacts the transport vehicle 322, and the transport vehicle 322 is driven along the guide slope 3244. The horn 3243 rotates, causing its other end to rotate toward the hook 3242, allowing the horn 3243 to avoid the transport vehicle 322. The hook can then pass under the transport vehicle 322. After the hook disengages from the transport vehicle 322, the horn 3243 resets, the sixteenth linear slide module 3245 resets, the other end of the horn 3243 contacts the transport vehicle 322, and one end of the horn 3243 contacts the hook 3242 and is subjected to force, preventing the horn 3243 from rotating toward one end and thus pushing the transport vehicle 322.

[0055] The working process of this invention is as follows: the vibratory feeder 111 feeds out bolts one by one, then the lifting device raises the bolts, the sorting fixture 134 grabs the bolts, the sliding assembly 121 transports the tray 410 to the second lifting assembly, the second lifting assembly raises the tray 410, the sorting fixture 134 then grabs the fuel injector from the tray 410 and adjusts the installation angle of the fuel injector, then the fuel injector and bolt are simultaneously placed on the transfer fixture 210, the transfer fixture 210 separates the two connected fuel injectors, and then the transfer module 220 transfers the fuel injector and bolt from the transfer fixture. The vehicle is removed from the fixture 210. At this time, the push-pull assembly 324 sends the transport vehicle 322 into the conveying track 321. Then, the limiting component and the clamping assembly 323 cooperate to position the cylinder. Then, the transfer module 220 installs the fuel injector and bolt onto the cylinder. Then, the tightening assembly descends, and the tightening tool 3123 contacts the bolt. The fourth motor 3121 drives the tightening tool 3123 to rotate and detects the torque of the bolt through the torque sensor 3127 to ensure that the bolt is tightened. Then, the push-pull assembly 324 sends the transport vehicle 322 out of the conveying track 321.

[0056] In summary, this invention provides an automatic fuel injector installation device. A bolt feeding module 110 automatically feeds out bolts one by one. Two fuel injector feeding modules 120 are used for single-pipe fuel injector feeding and double-pipe fuel injector feeding, respectively. A sorting module 130 picks up bolts from the bolt feeding module 110, then removes the single-pipe fuel injector, and places the single-pipe fuel injector and bolt onto a transfer fixture 210. It then picks up bolts and double-pipe fuel injectors again, and loads them onto the transfer fixture 210. The transfer fixture 210 then moves closer to the cylinder body. A transfer mechanism installs the single-pipe and double-pipe fuel injectors from the transfer fixture 210 onto the cylinder body of the positioning device 320. The bolts are then initially installed onto the cylinder body, and finally, the bolts are tightened by the tightening module 310, locking the fuel injectors onto the cylinder body. This achieves automated fuel injector installation, ensuring installation quality and improving production efficiency.

[0057] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the counting principle of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
