The rotation positioning module A2 in this mechanism is used to rotate the injection ring 100 to a predetermined angle, and can rotate the injection ring 100 to a predetermined state where the lug 101 is located at a corresponding angle, so as to facilitate the subsequent steps to process to the corresponding position; the coding and marking module A3 is used to code and mark the injection ring 100, and mark information such as the processing team and processing time on the injection ring 100, so as to facilitate the subsequent responsibility tracking and problem tracing; the hole penetration detection module A4 is used to check whether the radial through hole 102 on the side of the injection ring 100 is qualified, such as whether it is penetrated and whether the position setting is accurate; the size detection module A5 is used to detect the outer diameter of the injection ring 100, and is particularly used to detect the width of the radial sealing groove 103 at the upper end. and smoothness to ensure the smooth assembly of the sealing ring and the predetermined sealing effect; after the inspection, the classification and discharge module A6 will remove and output the NG materials, and the removed materials will be classified and output separately according to the NG reasons, which is beneficial for quality inspectors to find the distribution of NG problems, help to adjust or check related processing equipment in time, and also help to quickly adjust the NG materials that can be saved to control costs; the injection ring 100 is transferred in sequence between the modules by the transfer component A7, realizing a pipeline processing flow with a high degree of automation; in addition, the control computer, as the calculation and control center, coordinates and controls the cooperation between the modules and the transfer component A7 to ensure the orderly and efficient realization of positioning, detection, and classification and output of NG materials.

[0030] like Figure 4 As shown, the rotary positioning module A2 includes a rotary positioning platform A8 disposed on the frame 400, a positioning station is formed on the top surface of the rotary positioning platform A8, and a plurality of positioning detection components A9 are disposed on the side. The top surface of the rotary positioning platform A8 is rotatably connected to a first rotary table surface A10, and the first rotary table surface A10 is connected to a first rotary drive component A11; the positioning detection component A9 includes a first laser generator and a first receiver located on both sides of the positioning station and arranged oppositely, and the first laser generator and the first receiver are adapted to the height of the lug 101 at the upper end of the injection ring 100. A spare detection camera A12 is also disposed on the side of the rotary positioning platform A8, and the spare detection camera A12 is fixed on the frame 400 and aligned with the positioning station, and is used to further assist in confirming whether the positioning is in place through images, and the spare detection camera A12 is connected to the control computer.

[0031] Specifically, the rotary positioning platform A8 is used to rotate the injection ring 100 to a predetermined angle. The injection ring 100 is placed on the first rotating table A10 above it. The first rotating drive component A11 drives the first rotating table A10 to rotate with the injection ring 100. The first rotating drive component A11 can be a first driving motor arranged on the frame 400. The positioning detection component A9 emits a laser from the first laser generator, and the first receiver receives the emitted laser signal. The height of the two is adapted to the height of the lug 101 at the upper end of the injection ring 100. When the first receiver does not receive a signal, it means that the signal is blocked by the lug 101, that is, it indicates the position of the lug 101, and realizes the detection of the rotation angle of the injection ring 100. The detection camera performs visual detection by image capture and analysis, which can be used as an auxiliary detection method to improve the accuracy of positioning.

[0032] like Figure 6 As shown, the hole penetration detection module A4 includes a hole penetration detection platform A13 arranged on the frame 400, and a penetration detection position is formed on the top surface of the hole penetration detection platform A13.

The air outlet nozzle A16 is connected to a flow detector, and the flow velocity detector is connected to a control computer.

[0033] Specifically, the penetration detection position on the hole penetration detection table A13 is used to place the fuel injection ring 100 to be subjected to hole penetration detection. An air outlet nozzle A16 is provided on the hole penetration detection table A13 through an arc-shaped mounting block A14. The air outlet nozzle A16 is located on the inner side of the fuel injection ring 100 and radially sprays gas outward. The position of the air outlet end of the air outlet nozzle A16 is adapted to the position of the radial through hole 102 on the fuel injection ring 100. The mounting block telescopic driving assembly A15 is used to drive the movement of the arc-shaped mounting block A14 so that the air outlet end of the air outlet nozzle A16 is close to the inner side of the fuel injection ring 100. The flow detector is used to detect the gas flow output by the air outlet nozzle A16 per unit time. The flow data is converted into a diameter through a flow formula, thereby realizing non-destructive detection of the radial through hole 102 and eliminating the flash phenomenon of small holes.

[0034] In this embodiment, the mounting block telescopic drive assembly A15 includes a pneumatic cylinder body arranged at the center of the hole penetration detection platform A13, and the arc-shaped mounting block A14 is connected to the pneumatic cylinder body through a radial connecting rod. A power chamber is formed between the inner end of the connecting rod and the pneumatic cylinder body. The gas extraction and discharge assembly of the power chamber is connected to drive the telescopic action of the connecting rod, thereby realizing the radial translation control of the arc-shaped mounting block A14.

[0036] Specifically, the size detection position on the rotating detection table A17 is used to place the oil injection ring 100 whose size is to be detected. The detection table base A18 of the rotating detection table A17 can be raised and lowered vertically, and the second rotating table surface A19 on the base can rotate circumferentially, so that the size detection component A22 can perform all-round detection of different height positions and 360-degree circumferential positions of the oil injection ring 100. The detection is comprehensive. The size detection component A22 is specifically implemented by camera No. 1 and camera No. 2. Camera No. 1 and camera No. 2 are arranged relatively to each other, and corresponding items are detected on the oil injection ring 100 between them.

[0037] In this embodiment, the second rotating drive component A20 includes a second driving motor arranged on the detection table base A18 and transmission-connected to the second rotating table surface A19, and the base lifting drive component A21 includes a detection table lifting cylinder vertically arranged on the frame 400 and the output end of which is connected to the detection table base A18.

[0038] like Figure 8 As shown, the classification discharging module A6 includes a discharging transfer table A23, on which a transfer position is formed, and at least two groups of NG material output conveyor belts A24 are vertically distributed on one side of the transfer position, and an NG piece top block A25 is slidably connected to the discharging transfer table A23, and a pushing assembly A26 is provided between the NG piece top block A25 and the discharging transfer table A23, and a discharging lifting drive assembly A27 is provided between the discharging transfer table A23 and the frame 400.

[0039] Specifically, the transfer position on the discharging transfer table A23 is used to temporarily store the injection ring 100 that has completed coding and testing, which is convenient for the transfer of different first transfer components A7. A plurality of groups of NG material output conveyor belts A24 are arranged on the side of the discharging transfer table A23. The discharging lifting drive component A27 can control the lifting action of the discharging transfer table A23, so that the transfer position and the upstream ends of different NG material output conveyor belts A24 are connected at the same height. According to different NG reasons, the NG piece top block A25 can push the NG piece onto the conveyor belt after the transfer position corresponds to the corresponding NG material output conveyor belt A24, so as to realize the removal of NG pieces. For qualified products, they are transferred to the subsequent workstation by the first transfer component A7.

[0040] In this embodiment, the push assembly A26 includes an NG piece push cylinder disposed on the discharge transfer table A23, the NG piece push cylinder is located on the opposite side of the NG material output conveyor belt A24, and the output end of the NG piece push cylinder is connected to the NG piece push block A25 for pushing the NG material to the NG material output conveyor belt A24. The discharge lifting drive assembly A27 includes a discharge table lifting cylinder, the output end of which is connected to the discharge transfer table A23, for lifting the discharge transfer table A23 to be flush with one of the NG material output conveyor belts A24.

[0041] like Figure 5As shown, the coding and marking module A3 includes a coding platform A28, a coding mark position is formed on the top surface of the coding platform A28, and a laser coding component A29 is provided on the side. The laser coding component A29 is aligned with the coding mark position and is used to mark information including processing time, team number, etc. on the injection ring 100. The information is integrated into the two-dimensional code to improve the information capacity. A ring-shaped inner positioning block A30 is provided on the coding mark position. The inner positioning block A30 is fixed to the top surface of the coding platform A28 by bolts. The outer diameter of the inner positioning block A30 is adapted to the inner diameter of the injection ring 100, and a positioning groove is provided on its outer periphery. The number and distribution of the positioning grooves are adapted to the axial reinforcement ribs on the inner ring of the injection ring 100, and an easy-entry guide surface is provided at the upper end of the positioning groove.

[0042] Specifically, the coding mark position on the coding table A28 is used to place the injection ring 100 that has been positioned and is to be coded. The annular inner positioning block A30 is used to position the injection ring 100 to ensure that the coding is at the predetermined position. The laser coding assembly A29 is used to mark the information by laser engraving on the side wall surface of the injection ring 100 without affecting the structure of the sealing ring groove, etc. The inner positioning block A30 is fixed by bolts and has flexible detachability. The corresponding inner positioning block A30 can be replaced according to the specific model of the injection ring 100. The outer side of the inner positioning block A30 is provided with a radially concave positioning groove, which is used for the axial reinforcement rib of the inner ring of the injection ring 100 to be inserted for positioning. The easy-entry guide surface at the upper end is in the form of an inclined surface or an arc surface, which is helpful for the insertion of the axial reinforcement rib.

[0043] like Figure 1 , 2 As shown in Figures 9 and 10, the first transfer component A7 includes a horizontal slide rail arranged on the frame 400, and a mounting slide slidably connected to the horizontal slide rail, a sliding drive component A34 is provided between the mounting slide and the horizontal slide rail, and a claw hand component A31 is provided on the mounting slide through a claw hand lifting structure A49, and the claw hand component A31 includes an internal expansion type support hand A33 or a clamping type gripper A32. The horizontal slide rail includes a first slide rail A35 arranged between the feeding module A44 and the coding and marking module A3, and the installation slide includes a first slide rail A36 slidably connected to the first slide rail A35, and the first slide A36 is provided with two groups of internal expansion type support hands A33; the horizontal slide rail also includes a second slide rail A37 arranged between the coding and marking module A3 and the hole penetration detection module A4, and the installation slide includes a second slide rail A38 slidably connected to the second slide rail A37, and the second slide A38 is provided with a group of clamping type grippers A32; the horizontal slide rail also includes a third slide rail A39 arranged between the hole penetration detection module A4 and the classification and discharging module A6, and the installation slide includes a third slide rail A40 slidably connected to the third slide rail A39, and the third slide A40 is provided with two groups of internal expansion type support hands A33.

[0044] Specifically, the first transfer component A7 is composed of a gripper component A31 that specifically grabs the injection ring 100. The gripper component A31 can be an internal expansion type support hand A33 or a clamping type gripper A32, which can be selected according to the relevant structures on the specific workstation to be transferred and placed to ensure the smooth realization of the transfer. The gripper component A31 is set on the installation slide through the gripper lifting structure A49 and can move vertically. It is used to descend to grab or put down the injection ring 100, and to rise to lift the injection ring 100 to ensure smooth lateral movement. The installation slide can be laterally slidably set on the frame 400 through a horizontal slide rail. The sliding drive component A34 is used to provide a sliding driving force for the installation slide. The sliding drive component A34 can specifically include a linear motor module arranged parallel to the horizontal slide rail, and the installation slide is connected to the linear motor module. The gripper assembly A31 for transferring between the feeding module A44 and the coding and marking module A3 selects the inner expansion type support hand A33, which can avoid interference with related structures that limit the injection ring 100 from the outside at the feeding position of the feeding module A44. The gripper assembly A31 between the coding and marking module A3 and the hole penetration detection module A4 selects the clamping type gripper A32, which can avoid interference with the air outlet nozzle A16 on the inner side of the injection ring 100 at the penetration detection position. The gripper assembly A31 between the hole penetration detection module A4 and the classification discharge module A6 selects the inner expansion type support hand A33, which can avoid interference with the structure that limits the injection ring 100 from the outside at the transfer position. In addition, the transfer between these modules is realized through multiple sets of slide rails and sliders, which are independent and avoid the need for an excessively long slide rail to correspond to an excessively long driving stroke of the driver, making the setting more flexible.

[0045] like Fig. 9 , 10 As shown, the inward-expanding support arm A33 includes a support arm mounting platform fixed on the bottom surface of the mounting slide, and 4 groups of support rods A41 which are evenly distributed on the support arm mounting platform and can be radially extended and retracted, a support rod extension drive assembly is provided between the support arm mounting platform and the support rod A41, and an elastic cushion layer A43 is provided at the outer end of the support rod A41; the clamping type gripper A32 includes a clamping jaw mounting platform fixed on the bottom surface of the mounting slide, and 4 groups of L-shaped clamping jaws A42 which are evenly distributed on the clamping jaw mounting platform and can be radially slid, a clamping jaw extension drive assembly is provided between the clamping jaw mounting platform and the L-shaped clamping jaw A42, and an elastic cushion layer A43 is provided on the inner side of the vertical action section of the L-shaped clamping jaw A42.

[0046] Specifically, the main part of the internal expansion type support arm A33 is a support arm mounting platform, on which multiple groups of support rods A41 are radially arranged. The support rod telescopic drive assembly is used for the extension and retraction of the support rod A41. When extended, the elastic cushion layer A43 at the outer end of the support rod A41 is specifically attached to the inner wall of the injection ring 100 to achieve internal expansion type expansion and fixation. The elastic cushion layer A43 can be supported by rubber and other materials to avoid damage to the injection ring 100. The structure of the clamping type gripper A32 is similar, the difference is that the radially retractable L-shaped clamping claw A42 has a vertical action section pointing vertically downward, which is used to press on the injection ring 100 from the outside to achieve clamping type grasping and fixation. The inner side is provided with an elastic cushion layer A43, which also has a protective effect.

[0047] In this embodiment, the support rod telescopic drive assembly and the clamping jaw telescopic drive assembly both include a pneumatic structure, which includes a power chamber arranged between the support arm mounting platform and the inner end of the support rod A41, or between the clamping jaw mounting platform and the inner end of the L-shaped clamping jaw A42, and the power chamber is connected to the high-pressure gas generating assembly through an air duct.

[0048] As an optimization of this embodiment, the top surfaces of the rotation positioning table A8, the hole penetration detection table A13, the size detection table and the coding table A28 are all provided with an annular external positioning protrusion adapted to the outer diameter of the injection ring 100. The injection ring 100 is positioned in the external positioning protrusion to ensure the accurate implementation of related detection operations.

[0049] like Figure 1 , 3 As shown, a feeding module A44 is provided upstream of the rotation positioning module A2, and the feeding module A44 includes a feeding conveyor belt A50, and a V-shaped material blocking plate A45 is provided at the downstream end of the feeding conveyor belt A50, and a feeding waiting position is formed in the material blocking plate A45. At least one group of material blocking columns A46 are distributed on the side of the feeding conveyor belt A50 along the conveying direction, and the material blocking columns A46 are provided on the frame 400 through a material blocking telescopic component A47, and can be extended to the top of the feeding conveyor belt A50 to at least separate the feeding waiting position and the injection ring 100 in the upstream direction, and an idle detection component A48 for detecting whether the feeding waiting position is idle is provided on the side of the feeding waiting position. The material blocking telescopic component A47 includes a material blocking telescopic cylinder horizontally arranged on the frame 400 and perpendicular to the feeding conveyor belt A50, and a material blocking column A46 extending downward is rotatably connected to the output end of the material blocking telescopic cylinder, and the outer wall of the material blocking column A46 is coated with an elastic layer to avoid damaging the injection ring 100. The idle detection assembly A48 includes a second laser generator and a second receiver disposed on both sides of the loading and unloading position. Two groups of material blocking columns A46 are provided, each located between three adjacent injection rings 100 on the upstream side of the material blocking plate A45.

[0050] Specifically, the loading module A44 is located at the front end of the assembly line, and is used to input the spray ring 100 to be processed. It is mainly transmitted and input by the loading conveyor belt A50. The spray ring 100 is transmitted to the downstream end. The V-shaped baffle at the downstream end blocks the spray ring 100 at the loading waiting position here for the first transfer component A7 to grab. Since the spray ring 100 is arranged along the transmission direction of the conveyor belt, in order to at least separate the spray ring 100 at the loading waiting position, a blocking column A46 is provided on the frame 400, and the blocking column A46 can be extended after the frontmost spray ring 100 passes. To prevent the oil injection ring 100 at the rear from getting close to ensure that the oil injection ring 100 at the loading position is removed smoothly, the idle detection component A48 is used to detect whether the loading position is idle, that is, whether the oil injection ring 100 therein is removed. When it is idle, the blocking column A46 can be controlled to retract to release the oil injection ring 100 at the rear to enter the loading position. The degree of automation is high. Moreover, when the oil injection ring 100 is detected on the loading position, the loading conveyor belt A50 can be set to stop rotating in time to reduce unnecessary friction between the conveyor belt surface and the bottom surface of the oil injection ring 100 and reduce wear. The second laser generator and the second receiver are arranged relative to each other, and the connecting line passes through the oil injection ring 100 at the loading position. Whether the second receiver receives the laser signal determines whether there is an oil injection ring 100 in the loading position, and the detection effect is accurate. The two sets of material blocking columns A46 can separate the three frontmost fuel injection rings 100, ensuring that the first fuel injection ring 100 is removed smoothly and that the second fuel injection ring 100 enters the loading and removal position smoothly.

[0051] The specific working principle of the pre-assembly inspection mechanism: the fuel injection ring 100 to be processed is placed on the downstream side of the loading conveyor belt A50, and the fuel injection ring 100 is transported forward by the loading conveyor belt A50. The first fuel injection ring 100 in the front enters the loading and waiting position, and the rear blocking column A46 extends out to separate the second fuel injection ring 100. Then the first transfer component A7 grabs the first fuel injection ring 100 and transfers it to the positioning station on the rotary positioning table A8. The rotary positioning table A8 rotates, and the first laser generator and the first receiver detect the angle information, and stop rotating after it is in place; then the first transfer component A7 transfers the fuel injection ring 100 to the coding mark position on the coding table A28, and the laser coding component A29 marks the traceability QR code on the corresponding position of the outer wall of the fuel injection ring 100; then the first transfer component A7 transfers the fuel injection ring 100 to the through detection position on the hole through detection table A13, and the gas outlet nozzle A16 outputs gas through the flow The detector detects the flow rate per unit time and transmits the data to the control computer, which converts it into the diameter of the hole; then the first transfer component A7 transfers the injection ring 100 to the size detection position of the rotating detection table A17, the second rotating table A19 rotates, and the detection table base A18 rises and falls at a certain interval, and two groups of cameras No. 1 and No. 2 detect the injection ring 100 and send the detection data to the control computer; then the first transfer component A7 transfers the injection ring 100 to the transfer position of the discharge transfer table A23, and according to the relevant data sent, the control computer calculates and analyzes whether the injection ring 100 is qualified. If the result is judged to be an NG part, the discharge transfer table A23 is raised and lowered to the corresponding height and flush with the corresponding classification output conveyor belt, and the NG part top block A25 pushes the injection ring 100 to the upstream end of the conveyor belt. If the result is judged to be a qualified part, it waits for the transfer mechanism of the subsequent assembly mechanism to grab it.

[0052] like Figure 11-19As shown, the radial sealing ring assembly mechanism B1 includes a frame 400, on which a No. 1 injection ring carrier B2 is slidably connected. The No. 1 injection ring carrier B2 is driven to move by a No. 1 carrier translation drive assembly B28, and can move between a receiving station for receiving the injection ring 100 that has been tested and an assembly station for assembling the radial sealing ring 200 onto the injection ring 100; the frame 400 is also provided with a sealing ring transfer table E3 and a sealing ring stacking module E1 for vertically distributing and storing the radial sealing ring 200, the sealing ring transfer table E3 and the sealing ring stacking module E 1 is provided with a sealing ring transfer structure E2, which is used to remove the radial sealing ring 200 at the upper end of the sealing ring stacking module E1 and transfer it to the sealing ring transfer table E3; a sealing ring transfer structure B3 is provided between the sealing ring transfer table E3 and the assembly station, which is used to pick up the radial sealing ring 200 on the sealing ring transfer table E3 and carry the radial sealing ring 200 to dock with the outer side of the upper end of the injection ring 100; a sealing ring assembly structure B4 is provided on the assembly station, which is used to pull down the radial sealing ring 200 on the sealing ring transfer structure B3 and press it down to make it fit onto the radial sealing groove 103 of the injection ring 100.

[0053] Specifically, the radial sealing ring 200 assembly mechanism is used to assemble the radial sealing ring 200 on the oil injection ring 100. An annular installation step with the step surface facing upward is provided on the outer side of the upper end of the oil injection ring 100. The radial sealing ring 200 needs to be sleeved on the radial sealing groove above the installation step. In this mechanism, the oil injection ring carrier B2 is used to receive qualified parts that have been inspected before assembly at the material receiving station, and move them to the assembly station for assembly of the radial sealing ring 200. The radial sealing ring 200 to be assembled is stored in a sleeved manner on the sealing ring stacking module E1, and is arranged vertically, with the top and bottom ends of adjacent sealing rings connected. The sealing ring transfer structure E2 is used to transfer the radial sealing ring 200 at the uppermost end of the sealing ring stacking module E1. The ring 200 is removed and transferred to the sealing ring transfer table E3. The sealing ring transfer table E3 is used for the transition between the sealing ring stacking module E1 and the sealing ring transfer structure B3. The removed radial sealing ring 200 is transferred and sleeved on the sealing ring transfer structure B3. The sealing ring transfer structure B3 carries the radial sealing ring 200 to the corresponding position on the upper end of the injection ring 100. The sealing ring assembly structure B4 is used to push the sealing ring down to the corresponding installation position, and also applies a certain downward pressure to the radial sealing ring 200 so that the bottom end of the sealing ring is in contact with the installation step to ensure that it is installed in place. The mechanism has a high degree of automation and can realize a series of actions such as receiving and assembling the injection ring 100, supporting the sealing ring, and assembling the sealing ring, and the assembly efficiency is high.

[0054] like Fig.12 , 13As shown, the sealing ring stacking module E1 includes a plurality of vertical rods E5 surrounding a cylindrical sleeve column E4, and a clearance gap E6 is formed between adjacent vertical rods E5 to allow the upper supporting material pawl E21 of the sealing ring transfer structure E2 to pass through, and a tray E7 with an outer diameter larger than the cylindrical sleeve column E4 is vertically slidably arranged between the vertical rods E5, the sealing ring is axially distributed and clamped on the cylindrical sleeve column E4, and is located above the tray E7, and a tray pushing assembly E11 is provided between the tray E7 and the frame 400. The sealing ring stacking module E1 includes 6 groups distributed circumferentially on the turntable E8, the turntable E8 is rotatably connected to the frame 400, and is driven to rotate by the turntable rotation drive assembly E18, and a clearance hole E9 is provided on the turntable E8 below the tray E7 to allow the tray pushing assembly E11 to pass through; the sealing ring stacking module E1 also includes an annular base E28, the vertical rod E5 is vertically fixed on the top surface of the annular base E28, and the annular base E28 is detachably fixed on the turntable E8 through a quick fixing structure E15; a plurality of first clearance grooves E10 are evenly distributed circumferentially on the tray E7 to allow the upper supporting material pawl E21 to extend into, and the first clearance grooves E10 are open radially outward; the tray pushing assembly E11 includes a first linear drive vertically fixed on the frame 400, and the output end of the first linear drive can pass through the clearance hole E9 to push the tray E7 upward.

[0055] Specifically, the sealing ring stacking module E1 is composed of a plurality of vertical rods E5, and the vertical rods E5 are distributed in a circular shape to form a cylindrical sleeve column E4, which is used to sleeve the radial sealing ring 200, and the clearance gap E6 between the vertical rods E5 is used for the upper support material ratchet E21 of the sealing ring transfer structure E2 to enter, so as to ensure that the uppermost sealing ring can be removed by means of internal support, and a vertically liftable tray E7 is also provided on the cylindrical sleeve column E4, and the tray E7 is driven by the tray pushing assembly E11 to be able to rise and fall, and is mainly used to push the sealing ring on the cylindrical sleeve column E4 upward as a whole, so as to ensure that the uppermost sealing ring is close to the upper end, so as to facilitate the removal of the upper support material ratchet E21. There are multiple groups of sealing ring stacking modules E1, which are circumferentially distributed on the turntable E8. The turntable E8 can rotate the sealing ring stacking modules E1 with installed sealing rings to the bottom of the sealing ring transfer structure E2 for the sealing ring transfer structure E2 to remove them. The sealing ring stacking modules E1 with all the sealing rings removed can be rotated out to replenish the radial sealing rings 200 in time. A clearance through hole E9 is provided on the turntable E8 below each group of sealing ring stacking modules E1. The clearance through hole E9 is used to ensure that the corresponding sealing ring stacking module E1 can be smoothly pushed and matched by the telescopic end of the tray pushing assembly E11 when the corresponding sealing ring stacking module E1 is rotated to the bottom of the sealing ring transfer structure E2. The tray pushing assembly E11 can be specifically realized by a first linear drive such as a cylinder arranged vertically. The output end of the first linear drive extends to lift the tray E7 upward. The pushing effect is stable. When not needed, it can be lowered and exited from the clearance through hole E9 to ensure the normal rotation of the turntable E8. The annular base E28 of the sealing ring stacking module E1 is detachably fixed to the turntable E8, so that after the sealing rings are taken out and turned out, they can be removed in time for easy replenishment. Handles E17 for easy lifting can also be provided on both sides of the annular base E28. After replenishment is completed, it can also be easily fixed on the turntable E8, which is flexible to operate. In addition, a first clearance groove E10 is provided on the radial outer side of the tray E7 for the entry of the upper support material ratchet E21, ensuring that the sealing rings closest to the tray E7 can be smoothly and stably removed.

[0056] In this embodiment, the quick fixing structure E15 includes an L-shaped lock E16 that is rotatably connected to the top surface of the turntable E8 through a locking bolt. One annular base E28 corresponds to two L-shaped locks E16, and the horizontal fixing portion of the L-shaped lock E16 is in close contact with the annular base E28. The L-shaped lock E16 can rotate along the horizontal plane. When it needs to be fixed, its horizontal fixing portion is located above the annular base E28. By further tightening the locking bolt, the horizontal fixing portion can be pressed against the annular base E28 to ensure a stable fixation. The tray E7 has plug holes evenly distributed circumferentially, and the vertical rod E5 is provided with plug holes. The turntable rotation drive assembly E18 includes a first circumferential driver arranged on the frame 400, and the output end of the first circumferential driver is transmission-connected to the turntable E8.

[0059] Specifically, the pawl expander E19 is composed of multiple groups of upper supporting material pawls E21 that move radially outward to achieve the effect of expanding the sealing ring.

[0061] Specifically, since the radial sealing ring 200 is manually sleeved on the cylindrical sleeve column E4, the inner ring may be outside or twisted during the sleeve process and the pushing process of the pallet E7. The detection camera B5 detects the abnormality by visual means, and the expander longitudinal movement structure can control the ratchet expander E19 to move the sealing ring to the top of the reversed material basket B6 for removal when the reversed installation abnormality is detected.

The second elastic component E35 includes a second spring which is sleeved on the second cross bar and compressed between the second abutment block and the lower pawl seat.

[0064] like Fig.17As shown, the sealing ring transfer structure B3 includes a docking tube B12 with an opening facing downward, and a plurality of second make-way grooves B13 extending vertically and open at the lower end are evenly distributed circumferentially at the lower end of the docking tube B12. The docking tube B12 is slidably connected to the docking tube connecting hole B14 of the annular assembly base B30, and is driven to rise and fall by the docking tube lifting drive component B29.

[0065] Specifically, the sealing ring transfer structure B3 receives the sealing ring on the sealing ring transfer table E3 through the docking sleeve B12, and the second make way groove B13 at the lower end of the docking sleeve B12 is used for the passage of the lower supporting material pawl E32, so that the lower supporting material pawl E32 can radially shrink to move the sealing ring onto the docking sleeve B12, and the lower end of the docking sleeve B12 is open, so that it can be sleeved and docked with the upper end of the injection ring 100, and an assembly base B30 is relatively slidably arranged outside the docking sleeve B12, and the assembly base B30 can be moved downward relative to the docking sleeve B12 to push the sealing ring at the lower end out of the docking sleeve B12, and the auxiliary sealing ring assembly structure B4 moves the sealing ring to the injection ring 100.

[0066] like Fig.18 , 19 As shown, the sealing ring assembly structure B4 includes a disengagement frame B16 vertically slidably connected to the frame 400, and the disengagement frame is driven by a disengagement frame lifting drive assembly B19 to be able to move vertically up and down. The disengagement frame B16 is penetrated by a disengagement through hole B17 that allows the sealing ring transfer structure B3 to carry the radial sealing ring 200 to pass vertically, and at least two disengagement plates B18 are evenly distributed circumferentially on the outer side of the disengagement through hole B17. The disengagement plates B18 are slidably connected to the disengagement frame B16 and driven to move by the disengagement plate in-and-out drive assembly B20, so that the front end of the disengagement plate B18 can extend above the radial sealing ring 200 to disengage the radial sealing ring 200 from the docking tube B12 of the sealing ring transfer structure B3 to the injection ring 100, and press it downward.

[0067] Specifically, a peeling through hole B17 is provided on the peeling frame B16, which is used for the sealing ring transfer structure B3 to carry the radial sealing ring 200 vertically through. The inner side of the peeling piece B18 is arc-shaped, which is adapted to the shape of the sealing ring and the injection ring 100. The peeling piece in and out driving assembly B20 drives the peeling piece B18 to move radially, and the inner end of the peeling piece B18 extends to the upper end of the sealing ring. When the peeling frame B16 descends, the peeling piece B18 thereon can peel the sealing ring off and press it down to the preset position to assemble it in place.

[0070] Specifically, after the No. 1 fuel injection ring carrier B2 is assembled at the assembly station, it will also move to the flipping station. The flipping station is used to flip the fuel injection ring 100 through the flipping structure B21 so that the sealing groove at the lower end faces upward, which is convenient for the subsequent assembly of the end face sealing ring assembly mechanism. The flipping structure B21 is specifically realized by a flipping clamp B24 that can rotate along the vertical plane. The flipping clamp B24 can clamp the fuel injection ring 100 by closing two L-shaped claws. The flipping lifting drive assembly is used to lower the flipping clamp B24 to grab the fuel injection ring 100 to be flipped or place the flipped fuel injection ring 100. The flipping drive assembly B27 is used to drive the flipping clamp B24 to rotate 180 degrees with the fuel injection ring 100, which can stably achieve the flipping effect of the fuel injection ring 100. The setting of the protective pad can avoid damage to the outer wall of the fuel injection ring 100, and the fitting gap ensures the stability of the grasping.

[0071] In this embodiment, a platform slide rail B22 is provided on the frame 400, and the platform slide rail B22 passes under the disengagement frame B16 of the sealing ring assembly structure B4.

[0072] The specific working principle of the radial sealing ring assembly mechanism: the injection ring 100 that is qualified before assembly is transferred to the No. 1 injection ring carrier B2 at the material receiving station, and the No. 1 injection ring carrier B2 moves to the assembly station to wait for the assembly of the radial sealing ring 200. At the same time, the upper support material pawl E21 of the sealing ring transfer structure E2 moves in a retracted state into the uppermost radial sealing ring 200 on the cylindrical sleeve column E4, and then expands to open the sealing ring for removal, and then transfers it to the lower support material pawl E32 of the sealing ring transfer station E3, and is opened by the lower support material pawl E32 to obtain it. Afterwards, the sealing ring turntable E3 moves to the bottom of one end of the moving path of the sealing ring transfer structure B3, and the lower end of the docking tube B12 descends and extends into the lower supporting material pawl E32. The lower supporting material pawl E32 is retracted to put the sealing ring on the lower end of the docking tube B12. Then, the docking tube B12 moves to dock to the upper end of the injection ring 100, and then the assembly base B30 descends a certain distance relative to the docking tube B12 and then rises and resets. Then the peeling piece B18 extends out, and its inner end enters the position between the sealing ring and the assembly base B30. Then, the peeling piece B18 descends to push the sealing ring down to the injection ring 100, and further descends to press the sealing ring against the radial sealing groove 103 of the injection ring 100. After the assembly is completed, the docking tube B12 and the peeling piece B18 are withdrawn. Afterwards, the No. 1 fuel injection ring carrier B2 moves the fuel injection ring 100 to the flipping station, the flipping jaw B24 descends to grab the fuel injection ring 100 and then lifts it up, the flipping jaw B24 rotates 180 degrees to make the lower end of the fuel injection ring 100 face upward, and then puts it back on the No. 1 fuel injection ring carrier B2 to be grabbed by the subsequent end face sealing ring assembly mechanism.

[0073] like Figure 20-22 As shown, the end face sealing ring assembly mechanism C1 includes a frame 400, on which a No. 2 oil injection ring carrier C2 is slidably connected. The No. 2 oil injection ring carrier C2 is driven to move by a No. 2 carrier translation drive assembly C24, and can move between a receiving station for receiving an oil injection ring 100 assembled with a radial sealing ring and an assembly station for assembling an end face sealing ring 300 onto the oil injection ring 100; the frame 400 is also provided with another set of sealing ring transfer tables E28 and another set of sealing ring stacking modules E1 for vertically distributing and storing the end face sealing rings 300. A corresponding sealing ring transfer structure E2 is provided between the sealing ring turntable E28 and the sealing ring stacking module E1, which is used to remove the end face sealing ring 300 at the upper end of the sealing ring stacking module E1 and transfer it to the sealing ring turntable E28; a sealing ring transfer structure C25 is provided between the sealing ring turntable E28 and the No. 2 injection ring carrier C2, which is used to remove the end face sealing ring 300 on the sealing ring turntable E28, and after docking with the upper end of the injection ring 100 on the assembly station, push the end face sealing ring 300 downward into the end face sealing groove 104 at the upper end of the injection ring 100.

[0074] Specifically, the end face sealing ring assembly mechanism is used to assemble the end face sealing ring 300 on the oil injection ring 100 after the radial sealing ring is assembled and turned over. The sealing ring is clamped in the end face sealing groove 104 on the upper end face of the oil injection ring 100. The oil injection ring 100 is placed on the oil injection ring carrier C2, and the oil injection ring carrier C2 realizes the transfer action between each station. The sealing ring to be installed is sleeved and stacked on the sealing ring stacking module E1, and is distributed axially. Adjacent sealing rings do not overlap radially to ensure the sequential grabbing of the sealing ring transfer structure E2. The sealing ring transfer structure E2 is used to pick up the uppermost sealing ring of the sealing ring stacking module E1 from above and move it to the sealing ring transfer table E28. The sealing ring transfer structure C25 is used to pick up the sealing ring on the sealing ring transfer table E28 from above. The grippers of both are facing downward, and the sealing ring transfer table E28 is used for the transfer and transition of the sealing rings between the two. After the sealing ring transfer structure C25 picks up the sealing ring, it enters the assembly station and assembles it to the predetermined position. This assembly mechanism has a high degree of automation and good assembly efficiency.

[0075] like Fig. 20 , 21 As shown, the sealing ring transfer structure C25 includes a transfer base C3, a ring-shaped transfer cylinder C4 is provided on the bottom surface of the transfer base C3, a push ring C5 is sleeved on the outer side of the transfer cylinder C4, a push ring lifting structure C6 is provided between the push ring C5 and the transfer base C3, the transfer base C3 is connected to the transfer lifting structure C7, a transfer transverse structure C8 is provided between the transfer lifting structure C7 and the frame 400, and a positioning auxiliary structure C9 is also provided radially outside the push ring C5.

The lower part of the inner side of the arc-shaped positioning piece C10 is provided with an arc-shaped docking groove C12. The docking groove C12 is in contact with the outer wall of the upper end of the injection ring 100. A transfer positioning gap C13 is formed between the inner wall of the upper end of the arc-shaped positioning piece C10 and the outer wall of the transfer cylinder C4 to allow the end face sealing ring 300 and the push ring C5 to pass through.

[0076] Specifically, the sealing ring transfer structure C25 transfers the sealing ring through the transfer cylinder C4. The transfer cylinder C4 is set on the frame 400 through the transfer lifting structure C7. The transfer cylinder C4 descends to the lower end and enters the radial inner side of the sealing ring on the lower support material pawl E32. The lower support material pawl E32 is retracted to achieve the effect of clamping the sealing ring on the transfer cylinder C4. The transfer transverse movement structure C8 is used for driving the movement between the sealing ring transfer position and the No. 2 injection ring carrier C2. A push ring C5 is also sleeved on the outside of the transfer cylinder C4. The push ring C5 can push the sealing ring at the lower end into the end face sealing groove 104 after the transfer cylinder C4 is docked on the injection ring 100, so as to achieve the effect of transfer and assembly. In addition, the positioning auxiliary structure C9 is used to position the injection ring 100 from the upper end to ensure that the injection ring 100 and the transfer cylinder C4 are in a coaxial position to ensure the accurate pushing in of the sealing ring. The arc-shaped positioning piece C10 can move radially, and the inner side wall of its lower end is provided with a radially outwardly concave docking groove C12. When positioning, the positioning groove of its lower end fits with the outer side of the upper end of the injection ring 100, and the inner side wall above the groove forms an annular transfer positioning gap C13 with the outer side wall of the transfer cylinder C4, which is used for the axial movement of the push ring C5 and the sealing ring. In addition, the radial depth of the docking groove C12 is adapted to the thickness of the end face sealing ring 300 or the push ring C5, ensuring that both can move and further ensuring accurate assembly.

The radial in-and-out drive component C11 includes an in-and-out drive cylinder fixed to the bottom of the installation extension C15, and an arc-shaped positioning sheet C10 is fixed to the output end of the in-and-out drive cylinder.

[0079] Specifically, a clearance groove C14 is provided at the lower end of the transfer cylinder C4, and the clearance groove C14 is used for the passage of the lower supporting material pawl E32, ensuring that the lower supporting material pawl E32 is smoothly withdrawn to clamp the sealing ring on the transfer cylinder C4. The outer diameter of the transfer cylinder C4 is adapted to the diameter of the inner wall of the end face sealing groove 104, that is, the outer wall of the transfer cylinder C4 and the inner wall of the end face sealing groove 104 are smoothly connected to ensure the accurate assembly of the sealing ring. The height of the height detection component C16 is adapted to the clearance groove C14, and its signal generator and signal receiver are located on the outside of the clearance groove C14, that is, the signal can radially penetrate the transfer cylinder C4, which can be used to detect the descending height of the transfer cylinder C4, ensuring that the sealing ring can be stably clamped to the corresponding position when the lower supporting material pawl E32 is withdrawn, and the height detection component C16 is fixed by the detector mounting plate C17 and bolts, and has flexible detachability.

The upper annular step and the lower annular step are used to limit the maximum descending stroke of the push ring C5 to prevent it from falling out.

[0081] like Fig. 22 As shown, the No. 2 oil injection ring carrier C2 is slidably connected to the frame 400 through a slide rail, and an annular positioning step C18 is provided on the top surface of the No. 2 oil injection ring carrier C2, and the outer diameter of the annular positioning step C18 is adapted to the inner diameter of the lower part of the oil injection ring 100; the No. 2 carrier translation drive assembly C24 includes a linear motor arranged on the frame 400, and the output end of the linear motor is connected to the No. 2 oil injection ring carrier C2; after the assembly at the assembly station is completed, the No. 2 oil injection ring carrier C2 is also moved to the downstream inspection station, and the inspection station is provided with an assembly completion inspection structure C19 and an NG rejection structure C20. The assembled inspection structure C19 includes a camera inspection component C21 arranged on the side of the inspection station, and the NG rejection structure C20 includes an NG material output conveyor belt C22. An internal expansion support arm C23 is provided between the upstream of the NG material output conveyor belt C22 and the inspection station. The internal expansion support arm is slidably connected to the upper part of the frame 400 and can be lifted vertically to grab the injection ring 100 that has been inspected at the inspection station and transfer the injection ring 100 with unqualified inspection results to the NG material output conveyor belt C22.

[0082] Specifically, the annular positioning step C18 on the No. 2 fuel injection ring carrier C2 is used to position and limit the fuel injection ring 100 thereon to ensure accurate docking and matching of related processes. The rear end of the moving path of the fuel injection ring 100 also involves a detection station. The assembly inspection structure on this station is used to inspect all assembled fuel injection rings 100, and the products with NG inspection results are rejected by the NG rejection structure C20 to improve the qualified rate of finished products. The assembly inspection structure C19 is specifically inspected by the camera inspection component C21 through vision. The image data captured by the camera inspection component C21 is transmitted to the control computer, and the control computer analyzes the inspection results. The NG material output conveyor belt C22 is used to output NG parts, and the internal expansion support C23 that can be raised and lowered and translated is used to grab NG parts and move them to the upstream of the NG material output conveyor belt C22 to achieve automatic rejection.

[0083] In this embodiment, the internal expansion arm support C23 includes a arm support mounting platform and three groups of arm support rods which are evenly distributed on the arm support mounting platform and can be radially retracted and extended. The arm support mounting platform is slidably connected to the upper part of the frame 400 through a arm support transverse movement frame and is connected to a arm support transverse movement driver. The arm support mounting platform can be slidably connected to the arm support transverse movement frame in a vertically liftable manner and is connected to a arm support lifting driver. A arm support rod retractable drive assembly is provided between the arm support mounting platform and the arm support, and an elastic cushion layer is provided at the outer end of the arm support.

[0084] The specific working principle of the end face sealing ring assembly mechanism: after the radial sealing ring is assembled and turned over so that the end face sealing groove 104 faces upward, the injection ring 100 is transferred to the second injection ring carrier C2 of the end face sealing assembly mechanism, and the second injection ring carrier C2 moves to the assembly station. At the same time, the sealing ring transfer structure E2 picks up an end face sealing ring 300 at the top of the cylindrical sleeve column E4 and transfers it to the sealing ring transfer table E28. After that, the seal ring transfer table E28 moves to the bottom of the seal ring transfer structure C25, the transfer cylinder C4 descends to the lower end and enters the radial inner side of the seal ring, the lower support material ratchet E32 is closed, and the seal ring sleeve is transferred to the transfer cylinder C4, and then the transfer cylinder C4 moves to the top of the oil injection ring 100 at the assembly station, and makes its lower end face almost touch the upper end face of the oil injection ring 100, and the arc positioning piece C10 moves inward, and its docking groove C12 touches the upper end of the oil injection ring 100, completing the positioning. After that, the push ring C5 moves downward, pushes the end face seal ring 300 into the end face seal groove 104, and appropriately presses down to make the lower end of the seal ring touch the bottom of the end face seal groove 104, and assembles in place, and the arc positioning piece C10 and the docking cylinder withdraw and reset. Afterwards, the No. 2 injection ring carrier C2 moves the injection ring 100 to the inspection station. The inspection camera component captures image data and transmits it to the control computer. The control computer calculates and analyzes. When the inspection result is NG, the internal expansion support C23 moves the NG part to the NG material output conveyor belt C22, and the conveyor belt transports the NG part to the corresponding collection area. Those with qualified inspection results are transferred to the subsequent pressure change testing mechanism.

It can reciprocate between a receiving position for receiving the injection ring 100 after the sealing ring is assembled and a pressure change test position below the pressure test assembly D35. A second transfer assembly D5 for transferring the injection ring 100 after the pressure change test to the visual inspection bench D3 is provided between the visual inspection bench D3 and the receiving position, and a visual inspection assembly D34 is provided on the side of the visual inspection bench D3.

[0086] Specifically, the pressure change detection mechanism is used to perform a pressure change test on the injection ring 100 after the radial sealing ring 200 and the end face sealing ring 300 are assembled, to detect whether its parameters such as pressure resistance are up to standard, so as to ensure the qualified rate of finished parts. The injection ring 100 to be tested is placed on the pressure change test bench D2, which is transferred to the pressure change test position for testing. The pressure test component D35 applies axial downward pressure to the injection ring 100 from above, and the pressure change of the pressure plate D8 after pressing in a corresponding distance realizes indirect measurement of the deformation amount. In addition, a visual inspection bench D3 and a visual inspection component D34 are also provided on the frame 400. By capturing the corresponding image data, the control computer or monitoring personnel further detect the situation after deformation, so as to improve the quality of the final output product.

The output end of the linear drive is connected to the pressure change test bench D2. A press calibration assembly D9 is provided on the pressure change test bench D2, and the height of the press calibration assembly D9 is adapted to the height of the injection ring 100.

[0088] Specifically, the pressure test assembly D35 is implemented by the pressure tester D6. The pressure plate D8 of the pressure tester D6 is used to apply pressure to the injection ring 100 from the upper end surface downward. The hydraulic system D36 provides the downward driving force, and the pressure sensor is used to detect the pressure value between the pressure plate D8 and the injection ring 100. The pressure tester D6 and the pressure change test bench D2 are set in multiple groups, which can provide a corresponding number of pressure change test positions, and can respectively test multiple injection rings 100. Moreover, each group is independent of each other to avoid mutual interference. In addition, since the pressure change test takes a relatively long time compared with other assembly processes, setting up multiple pressure change test positions helps to match the beat between each process and ensure the efficient operation of the injection ring sealing ring assembly line. The pressure change test bench D2 is set by sliding on a slide rail to ensure that it has a stable load-bearing capacity while sliding, and the linear drive is used to specifically drive the smooth movement of the pressure change test bench D2. The press calibration assembly D9 can ensure that the pressure output of the pressure tester D6 meets the design requirements, thereby improving the accuracy of the pressure change test.

The rotation of the positioning roller D21 can achieve the effect of driving the injection ring 100 to rotate. During the rotation process, the detection camera D20 captures relevant image data. Moreover, the roller seat D37 can be raised and lowered, so that for different models of injection rings 100, the positioning roller D21 can be raised and lowered to a suitable height to ensure that it matches the position suitable for contact with the outer side of the injection ring 100 and improve compatibility.

[0093] As a further optimization, unpowered rollers are arranged circumferentially on the outer side of the arc-shaped main body D17, which helps the oil injection ring 100 to be driven by the positioning roller D21 to rotate smoothly.
