[0002] With the development of today's society, vigorously promoting new energy projects is the general trend of the automotive industry. The motor oil injection ring is an indispensable part of the motor system of electric vehicles. The oil injection ring is assembled on the outside of both ends of the motor stator, and plays the role of sealing coolant in the radial and axial directions respectively.

[0003] In the current existing technology, there is no mature automated solution for the assembly of the seal ring of the fuel injection ring. Most assembly lines lack an automated radial seal ring assembly mechanism. Assembling the radial seal ring on the fuel injection ring still requires a lot of manual participation, resulting in a low degree of automation, low assembly efficiency and high assembly cost. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems in the prior art and to provide a radial sealing ring assembly mechanism for an oil injection ring sealing ring assembly line.

[0005] In order to achieve the purpose of the invention, the following technical solutions can be used: A radial sealing ring assembly mechanism of an oil injection ring sealing ring assembly line comprises a frame, an oil injection ring carrier is slidably connected to the frame, the oil injection ring carrier is driven to move by a carrier translation drive assembly, and can move between a material receiving station for receiving an oil injection ring that has been inspected and an assembly station for assembling a radial sealing ring onto the oil injection ring; The frame is also provided with a sealing ring transfer table and a sealing ring stacking module for vertically distributing and storing radial sealing rings. A sealing ring transfer structure is provided between the sealing ring transfer table and the sealing ring stacking module for removing the radial sealing ring at the upper end of the sealing ring stacking module and transferring it to the sealing ring transfer table. A sealing ring transfer structure is provided between the sealing ring transfer table and the assembly station, which is used to pick up the radial sealing ring on the sealing ring transfer table and connect the radial sealing ring to the radial sealing groove at the upper end of the oil injection ring; The assembly station is provided with a sealing ring assembly structure, which is used to pull down the radial sealing ring on the sealing ring transfer structure and press it down to be sleeved on a predetermined position on the oil injection ring.

[0006] The radial sealing ring assembly mechanism of the present invention is used to assemble the radial sealing ring of the oil injection ring. 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. The radial sealing ring needs to be sleeved on the radial sealing groove above the installation step. In this mechanism, the oil injection ring carrier is used to receive the qualified parts that have been inspected before assembly at the material receiving station, and move them to the assembly station for assembling the radial sealing ring. The radial sealing rings to be assembled are stored in a sleeve-connected manner on the sealing ring stacking module and are arranged vertically. The top and bottom ends of adjacent sealing rings are connected. The sealing ring transfer structure is used to transfer the radial sealing ring at the uppermost end of the sealing ring stacking module. The sealing ring is removed and transferred to the sealing ring transfer table. The sealing ring transfer table is used for the transition between the sealing ring stacking module and the sealing ring transfer structure. The removed radial sealing ring is transferred and sleeved on the sealing ring transfer structure, and the sealing ring transfer structure carries the radial sealing ring to the corresponding position on the upper end of the injection ring. The sealing ring assembly structure is used to push the sealing ring down to the corresponding installation position, and also exert a certain downward pressure on the radial sealing ring 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, supporting and taking out the sealing ring, and assembling the sealing ring, with high assembly efficiency.

[0007] In the radial sealing ring assembly mechanism of the above-mentioned injection ring sealing ring assembly line, the sealing ring stacking module includes a plurality of vertical rods surrounding a cylindrical sleeve column, and a clearance gap is formed between adjacent vertical rods to allow the upper support material pawl of the sealing ring transfer structure to pass through, and a tray with an outer diameter larger than the cylindrical sleeve column is vertically slidably arranged between the vertical rods, the sealing ring is axially distributed and clamped on the cylindrical sleeve column and is located above the tray, and a tray pushing assembly is provided between the tray and the frame.

[0008] The sealing ring stacking module is composed of a number of vertical rods, each of which is distributed in a circle to form a cylindrical sleeve column, which is used to sleeve the radial sealing ring. The clearance between the vertical rods is used for the entry of the upper support material ratchet of the sealing ring transfer structure to ensure that the uppermost sealing ring can be removed by internal support. A vertically liftable tray is also provided on the cylindrical sleeve column. The tray is driven by a tray pushing assembly to be able to rise and fall, and is mainly used to push the sealing ring on the cylindrical sleeve column upward as a whole to ensure that the uppermost sealing ring is close to the upper end, which is convenient for removing the upper support material ratchet.

A yielding through hole is provided on the turntable under each group of sealing ring stacking modules, and the yielding through hole is used to ensure that the tray of the corresponding sealing ring stacking module can be smoothly pushed and matched by the telescopic end of the tray pushing assembly when the corresponding sealing ring stacking module is turned to the bottom of the sealing ring transfer structure. The tray pushing assembly can be specifically realized by a first linear drive such as a cylinder arranged vertically, and the output end of the first linear drive extends to lift the tray upward, and the pushing effect is stable. When it is not needed, it can be lowered and exited from the yielding through hole to ensure the normal rotation of the turntable. The annular base of the sealing ring stacking module is detachably fixed to the turntable, so that it can be removed in time after the sealing ring is taken out and turned out for convenient replenishment, and handles for convenient lifting can also be provided on both sides of the annular base. After the replenishment is completed, it can also be easily fixed on the turntable, and the operation is flexible. In addition, a first clearance groove is arranged on the radial outer side of the tray for the entry of the upper support material ratchet to ensure that the several sealing rings closest to the tray can be picked smoothly and stably.

[0011] Specifically, the quick fixing structure includes an L-shaped lock buckle that is rotatably connected to the top surface of the turntable through a locking bolt.

Under the action of the first elastic component, the pawl seat has a first roller that rolls tightly on the first conical table. The first conical table is small at the bottom and large at the top, and a circular hole groove is opened at the lower end. The circular hole groove is conducive to lightweight and helps to prevent the first conical table from interfering with the related structure below when it moves downward. Through the lifting action of the first conical table, the radial distance between the first roller and the axis of the table can be controlled, thereby realizing the synchronous radial in and out action of the multiple groups of upper supporting material pawls to ensure the internal support effect.

[0017] Since the radial sealing ring is manually sleeved on the cylindrical sleeve column, the inner ring may be outside or twisted during the sleeve process and the pallet pushing process. The detection camera detects the abnormality by visual means. When the abnormality is detected, the expander longitudinal movement structure can control the ratchet expander to move the sealing ring to the top of the reversed material basket for removal. The detection camera is a prior art and will not be elaborated in detail.

[0018] In the radial sealing ring assembly mechanism of the above-mentioned injection ring sealing ring assembly line, the sealing ring turntable includes an annular turntable base arranged on the frame, and a plurality of lower supporting material pawls are circumferentially distributed on the top surface of the turntable base.

The flipping station is provided with a flipping structure, and the platform translation drive assembly can also move the oil injection ring platform from the assembly station to the flipping station.

[0027] The oil injection ring processed by the present invention needs to be sleeved with a radial sealing ring on the outer side of the upper end, and also needs to be installed with an end face sealing ring on the central sealing groove on the lower end face. For this reason, the oil injection ring carrier will be moved to the flipping station after the assembly station is completed.

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.

[0046] 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.

[0047] 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 ratchet expander E19 includes an expander mounting seat E20 and an upper supporting material ratchet E21 which is circumferentially distributed on the bottom surface of the expander mounting seat E20 and extends vertically. An upper retractable driving structure is arranged between the upper supporting material ratchet E21 and the expander mounting seat E20; the upper retractable driving structure includes A first conical truncated cone E22 is provided between the upper supporting material pawls E21, the upper supporting material pawls E21 are slidably connected to the expander mounting seat E20 through an upper pawl seat, a first roller E23 is provided on the upper pawl seat near the first conical truncated cone E22, the first roller E23 rolls on the conical surface of the first conical truncated cone E22, a first elastic component E24 is provided between the upper pawl seat and the expander mounting seat E20 to make the upper pawl seat have a tendency to move toward the first conical truncated cone E22, and the first conical truncated cone E22 is driven to rise and fall by a first lifting drive component E25.

[0050] 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. The upper supporting material pawls E21 are slidably connected to the bottom surface of the expander mounting seat E20 through the upper pawl seat. Under the action of the first elastic component E24, the pawl seat has a first roller E23 that rolls tightly on the first conical table E22. The first conical table E22 is small at the bottom and large at the top, and a circular hole groove is opened at the lower end. The circular hole groove is conducive to lightweight and helps prevent the first conical table E22 from interfering with the relevant structure below when it moves downward. Through the lifting action of the first conical table E22, the radial distance between the first roller E23 and the axis of the table can be controlled, thereby realizing the synchronous radial entry and exit action of the multiple groups of upper supporting material pawls E21 to ensure the internal support effect. The first lifting drive assembly E25 includes a second linear actuator vertically arranged on the expander mounting seat E20, and the output end of the second linear actuator is connected to the top surface of the first conical truncated cone E22.

The expander mounting seat E20 is fixed under the expander lifting seat, and the third linear driver is arranged on the expander lifting seat, and its output end passes through the expander mounting seat E20 and is connected to the first conical table E22.

[0052] 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.

[0055] like Figure 7As 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. The assembly base B30 is fixed to the bottom of the assembly lifting seat B15; the assembly lifting seat B15 is slidably connected to the lower side of the assembly transverse moving frame through a sliding rod, and can be lifted and lowered by the driving of the assembly lifting drive component, the assembly transverse moving frame is slidably connected to the upper part of the frame 400, and can be moved between the assembly station and the sealing ring turntable E3 by the driving of the third transverse moving drive component; the docking tube connecting hole B14 is exposed at the lower end of the docking tube B12, the outer side of which is used for the clamp sleeve of the radial sealing ring 200, and the inner side is used for docking with the upper end of the injection ring 100.

[0056] 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.

[0057] like Figure 8 , 9 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.

[0058] 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.

A protective pad is provided on the opposite side of the L-shaped claw body, and a fitting notch adapted to the outer diameter of the oil injection ring 100 is provided on the protective pad.

[0061] Specifically, after the assembly is completed at the assembly station, the fuel injection ring carrier B2 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 a 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.

[0062] In this embodiment, a carrier slide rail B22 is provided on the frame 400, and the carrier slide rail B22 passes under the disengagement frame B16 of the sealing ring assembly structure B4.

[0063] Specific working principle: the injection ring 100 that is qualified before assembly is transferred to the injection ring carrier B2 of the receiving station, and the 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 supporting material pawl E21 of the sealing ring transfer structure E2 moves in a folded 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 supporting material pawl E32 of the sealing ring transfer station E3, and is opened by the lower supporting 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 oil injection ring carrier B2 moves the oil injection ring 100 to the flipping station, the flipping jaw B24 descends to grab the oil injection ring 100 and then lifts it up, the flipping jaw B24 rotates 180 degrees to make the lower end of the oil injection ring 100 face upward, and then puts it back on the oil injection ring carrier B2 to be grabbed by the subsequent end face sealing ring assembly mechanism.
