Technical Field

[0001] This invention relates to the field of fuel injection pump assembly equipment, and more particularly to an automated fuel injection pump tubing spring assembly equipment. Background Technology

[0002] As the core component of a diesel engine's fuel injection system, the performance of the fuel injection pump directly determines the engine's power, economy, and emissions levels. Reliable assembly of the fuel lines and their connecting components is crucial for ensuring the normal operation of the fuel injection pump and preventing high-pressure fuel leakage.

[0003] The fuel injection pump mainly consists of a main pump body, valve seat, fuel line, plunger spring, and baffle plate. During manufacturing, the main pump body needs to be assembled with these four other parts. The valve seat at the bottom of the main pump body requires locking and finishing. The fuel line needs to be glued and then inserted into the side of the main pump body. The plunger spring needs to be mounted on the shaft at the top of the main pump body. After compressing the spring, the baffle plate is inserted into the upper end of the shaft. The upper end of the shaft is a stepped shaft, and the slot on the baffle plate has a T-shaped cross-section. (Refer to...) Figure 9 .

[0004] In this type of assembly, since it involves the assembly of multiple parts and multiple processes, the existing fuel injection pump needs to be assembled on multiple machines and with manual loading and unloading.

[0027] Example:

[0028] like Figures 1-9 As shown, the present invention proposes an automated oil injection pump tubing spring assembly device, comprising a frame 1, an electric turntable 2 mounted on the frame 1, and a feeding robot 3, an automatic locking mechanism 4, an oil inlet pipe dispensing and insertion mechanism 5, a spring feeding side-pressing mechanism 6, a baffle side-insertion mechanism 7, and a unloading robot 8 arranged around the electric turntable 2 on the frame 1. Multiple positioning carriers 9 are mounted on the rotating platform of the electric turntable 2. A fixed plate 10 is fixedly connected to the housing of the electric turntable 2. Rotary pressing cylinders 11 are fixedly connected to the fixed plate 10 on the sides of the automatic locking mechanism 4, the oil inlet pipe dispensing and insertion mechanism 5, and the spring feeding side-pressing mechanism 6. The oil inlet pipe dispensing and insertion mechanism 5 includes an oil pipe. The components include a feeding machine 501, an oil pipe transfer robot 502, a positioning adsorption head 503, a magnet 504, a dispensing device 505, a rotating device 506, an insertion cylinder 507, and an oil pipe clamping cylinder 508. The positioning adsorption head 503 is provided with a positioning groove, and the magnet 504 is fixedly connected to the positioning adsorption head 503. The baffle side insertion mechanism 7 includes a baffle feeding machine 701, a baffle transfer robot 702, an XY moving module 703, a paddle 704, and a baffle clamping cylinder 705. The paddle 704 is provided with a clearance groove in the middle. A docking cylinder 13 is fixedly connected to the side of the baffle side insertion mechanism 7 on the frame 1. An oil nozzle 14 is fixedly connected to the moving platform of the docking cylinder 13.

[0029] A material tray 12 is provided on the frame 1 next to the unloading robot 8. The material tray 12 is used to receive the finished oil injection pump after it has been assembled.

[0030] The positioning carrier 9 includes a fixed base 901, a buffer base 902, and a positioning column 903. The fixed base 901 is fixedly connected to the rotating table of the electric turntable 2. The positioning column 903 is used to position and place the main pump body 15. A clearance hole is opened on the buffer base 902 to allow clearance for the lower end of the main pump body 15. A buffer spring 904 is provided between the buffer base 902 and the fixed base 901. When pressing the oil pipe 17, the buffer base 902 can slide on the fixed base 901 to provide elastic buffering during the assembly process, avoid deformation of the oil pipe 17, and improve product yield.

[0031] The spring feeding and side-pressure mechanism 6 includes a spring feeder 601, a spring transfer robot 602, and a side-pressure cylinder 603. The spring feeder 601 is used to feed the plunger spring 18. The spring transfer robot 602 is used to transfer the plunger spring 18 from the discharge end of the spring feeder 601 to the main pump body 15. The extension of the piston rod of the side-pressure cylinder 603 is used to press the top pressure oil pipe 17 completely onto the main pump body 15.

[0032] The tubing feeder 501 is used to feed the tubing 17. The tubing transfer robot 502 is used to drive the positioning suction head 503 to suction and transfer the tubing 17 from the discharge end of the tubing feeder 501 to the tubing clamping cylinder 508 for clamping. The tubing clamping cylinder 508 is driven to rotate one revolution by the rotating device 506 and then reset. During this process, the dispensing device 505 dispenses glue to the end of the tubing 17 that needs to be inserted into the main pump body 15. After the glue is dispensed, the tubing 17 is inserted into the main pump body 15 by the piston rod of the insertion cylinder 507 extending.

[0033] The baffle feeder 701 is used to feed the baffle 19. Before assembling the baffle 19, the XY moving module 703 drives the paddle 704 to rise and then move horizontally above the plunger spring 18 before pressing down, so as to avoid the plunger spring 18 interfering with the side insertion action of the baffle 19. Then the baffle transfer robot 702 clamps the baffle 19 at the discharge end of the baffle feeder 701 and transfers it to the main pump body 15. The XY moving module 703 is fixedly connected to the frame 1. The paddle 704 is fixedly connected to the moving table of the XY moving module 703. The baffle clamping cylinder 705 is fixedly connected to the output end of the baffle transfer robot 702.

[0034] The automatic fastening mechanism 4 includes an automatic screw fastening machine and a fastening sleeve. The fastening sleeve is fixedly connected to the output end of the automatic screw fastening machine. The automatic screw fastening machine drives the fastening sleeve to rise and rotate. During the rising and rotating process, when the hexagonal groove of the fastening sleeve engages with the hexagonal protrusion of the valve seat 16, the fastening sleeve threads the valve seat 16 onto the main pump body 15.

[0035] The working principle of this invention is as follows: When this invention is in use, the main pump body 15 is grabbed by the loading robot 3 and loaded onto the positioning carrier 9 on the electric turntable 2. The main pump body 15 is positioned on the positioning column 903. After the main pump body 15 completes loading, the rotating table of the electric turntable 2 rotates to switch the work position.

[0036] First, the main pump body 15 will be rotated to the valve seat 16 locking position for valve seat 16 locking. The pressure head of the rotating clamping cylinder 11 will press down on the main pump body 15. The locking sleeve will be driven to rise and rotate by the automatic screw fastening machine. During the rising and rotating process, when the hexagonal groove of the locking sleeve is engaged with the hexagonal protrusion of the valve seat 16, the locking sleeve will thread the valve seat 16 onto the main pump body 15. Then the rotating clamping cylinder 11 will loosen the clamp and proceed to the next processing step.

[0037] Next, the main pump body 15 rotates to the oil pipe dispensing and insertion station. The pressure head of the rotating clamping cylinder 11 presses down on the main pump body 15. The oil pipe feeder 501 is used to feed the oil pipe 17. The oil pipe transfer robot 502 drives the positioning suction head 503 to suction and transfer the oil pipe 17 from the discharge end of the oil pipe feeder 501 to the gripper of the oil pipe clamping cylinder 508 for clamping. The rotating device 506 drives the oil pipe clamping cylinder 508 to rotate one revolution and then reset. During this process, the dispensing device 505 dispenses glue to the end of the oil pipe 17 that needs to be inserted into the main pump body 15. After the glue is dispensed, the oil pipe 17 is inserted into the main pump body 15 by the piston rod of the insertion cylinder 507 extending. Then the rotating clamping cylinder 11 is released to proceed to the next processing step.

[0038] Next, the main pump body 15 rotates to the spring feeding station, the pressure head of the rotating clamping cylinder 11 presses the main pump body 15 downward, the piston rod of the side pressure cylinder 603 extends to press the top pressure oil pipe 17 completely onto the main pump body 15, then the rotating clamping cylinder 11 loosens the clamp, the spring feeder 601 is used to feed the plunger spring 18, and the spring transfer robot 602 is used to transfer the plunger spring 18 at the discharge end of the spring feeder 601 to the main pump body 15.

[0039] Afterwards, the main pump body 15 rotates to the baffle loading station. The XY moving module 703 drives the paddle 704 to rise first and then move horizontally to above the plunger spring 18 and then press down to compress the plunger spring 18, so as to avoid the plunger spring 18 interfering with the side insertion action of the baffle 19. Then, the piston rod of the docking cylinder 13 extends, and the oil nozzle 14 docks with the oil pipe 17 to perform oil spraying. After the oil spraying is completed, the docking cylinder 13 resets. The baffle transfer robot 702 picks up the baffle 19 at the discharge end of the baffle loading machine 701 and transfers it to the side of the main pump body 15. Then, it drives the baffle 19 to move horizontally so that the slot of the baffle 19 is inserted into the shaft end of the main pump body 15. Then, the XY moving module 703 drives the paddle 704 to release the plunger spring 18. After the plunger spring 18 resets, it supports the baffle 19 on the main pump body 15 to complete the assembly of the baffle 19.

[0040] Finally, the main pump body 15 rotates to the unloading station, and the unloading robot 8 unloads the assembled main pump body 15 onto the loading tray 12 to complete the unloading.
