Description

Technical Field

[0001] This utility model relates to the technical field of lock cylinder assembly equipment, and in particular to an automatic lock cylinder assembly equipment. Background Technology

[0002] Existing single-opening lock cylinders, such as Figures 1 to 3 As shown, it typically includes a lock sleeve a, a lock cylinder b, a central rotor c, a rotating dial d, a finger turner e, a spring f, and a retaining ring g. The lock sleeve a has a through-hole a1 with a notch a2 in its middle that divides the a1 into two parts. The lock cylinder b has a keyhole b1 for the key to pass through. The central rotor c has a rotor groove c1 that mates with the tail of the key, and its upper end forms a plate-shaped rotor insert c2. The end of the finger turner e forms a knob e1 with a characteristic shape (such as cylindrical or square), and its other end has an open inner cavity e2. The lock cylinder... Both the end of the keyhole b1 away from the opening and the end of the rotary knob e away from the knob e1 are provided with a snap ring groove h that cooperates with the snap ring. The lock sleeve a has a protrusion a3 that protrudes along the axial direction of the lock cavity a1. The rotating wheel d has a meshing part d1 that protrudes along its axial direction and is adapted to the shape of the protrusion a3. The meshing part d1 is used to mesh with the locking mechanism (the lock cylinder and the locking mechanism are matched). The rotating wheel d has a slot d2 that is opened along its axial direction to cooperate with the rotor insert c2, so that when the rotor insert c2 is inserted, it can drive the rotating wheel d to rotate synchronously.

[0003] During assembly, firstly, the rotating wheel d is placed into the corresponding notch a2 in the middle of the lock sleeve a, ensuring it is coaxial with the lock cavities a1 on both sides of the notch a2 on the lock sleeve a. Then, the central rotor c and the lock cylinder b are inserted sequentially along one side of the lock cavity a1, with the central rotor c passing through the rotating wheel d to achieve coaxial linkage between the lock cylinder b and the rotating wheel d. Next, the spring f is placed into the inner cavity e2 of the finger twister e, and then the finger twister e is inserted along the other side of the lock cavity a1, with the end of the central rotor c passing through the inner cavity e2 of the finger twister e, thus ensuring the coaxial linkage between the lock cylinder b, the central rotor c, the rotating wheel d, and the finger twister e. Finally, retaining rings g are installed at the two gaps in the notch a2 to restrict the axial movement of the lock cylinder b and the finger twister e, preventing them from dislodging.

[0004] When a correctly matched key is inserted into the keyhole of the lock cylinder, it drives the lock cylinder, central rotor, rotating wheel, and finger turner to rotate synchronously, thereby opening the door lock. Thanks to its compact design and good security, it has been widely used in the market, especially as a lock cylinder for interior doors.

[0005] However, the assembly of single-opening lock cylinders currently relies mostly on semi-automatic or manual methods, using specific assembly tools, which leads to low production efficiency.

[0006] In addition, due to the structure of the single opening lock cylinder, it cannot be assembled along two sides after being placed horizontally as the double opening lock cylinder, and the difficulty of automatic assembly mainly concentrates on positioning accuracy and assembly stability, and thus still needs to be improved.

Detailed Implementation

[0037] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0038] Please see Figures 1 to 16 This is a preferred embodiment of an automatic lock cylinder assembly device, comprising a machine base, tooling, a conveying device, a lock cylinder assembly mechanism, a central rotor assembly mechanism, a lock assembly mechanism, a first snap ring assembly mechanism, a finger turner feeding mechanism, a spring feeding mechanism, a flipping mechanism, and a second snap ring assembly mechanism, as detailed below:

[0039] like Figure 5 As shown, the machine base 110 has a platform, which serves as the mounting base for multiple mechanisms;

[0040] like Figure 5 As shown, the tooling has a forward fixing position and a reverse fixing position. The forward fixing position is provided with a limiting piece that mates with the keyhole, and the reverse fixing position is provided with a knob limiting groove that mates with the knob limiting position at the end of the rotary knob.

[0041] Specifically, in this embodiment, the tooling includes a square plate-shaped base, and another square block-shaped fixing seat is fixed to one side of the upper surface of the base. The fixing seat is recessed downward to form a knob limiting groove that fits into the shape of the knob of the finger turner. The limiting piece is integrally fixed to the top surface of the base and located on one side of the fixing seat. The limiting piece is a plate-shaped insert structure, the purpose of which is to simulate a universal key so that it can be smoothly inserted into the keyhole of the lock cylinder. The lock cylinder is limited by the keyhole, so that the lock cylinder is kept perpendicular to the base. This facilitates the subsequent assembly of parts such as the lock sleeve, the central rotor, and the snap ring.

[0042] like Figure 5 As shown, a pair of limiting structures are provided on the upper surface of the base and on one side of the limiting piece. The two limiting structures form a limiting area with an upper opening that contacts the outer wall of the lock sleeve to restrict its swing. In this embodiment, the limiting structure is a pair of limiting shafts that are symmetrically distributed about the limiting piece. The limiting area between the two limiting shafts allows the protrusion on the side of the lock sleeve to fit in perfectly. Without the limiting structure, after the lock sleeve is fitted into the lock cylinder, it is in a state that can rotate axially relative to the lock cylinder. Therefore, the addition of the limiting structure can cooperate with the lock cylinder positioned by the limiting piece to limit and fix the entire lock sleeve, which facilitates the subsequent assembly process.

[0043] like Figure 16 As shown, the conveying device is used to drive the tooling to circulate along a closed rotary path.

[0044] like Figure 6 , 7 As shown, the lock cylinder assembly mechanism is used to grip the lock cylinder to the positive fixed position and allow the keyhole to be inserted into the limiting piece to maintain a vertical posture.

[0045] Specifically, in this embodiment, the lock cylinder assembly mechanism includes a lock cylinder loading position, a first swinging device, a first lifting device, a first gripper device, and a first jacking device. The first jacking device is used to vertically lift a single lock cylinder from the lock cylinder loading position. The first gripper device is used to grab the single lock cylinder after jacking. The first swinging device is used to swing the first gripper device along a circumferential path to the tooling above the corresponding position and make the lock hole of the lock cylinder face the limiting plate. The first lifting device is used to drive the first gripper device to vertically lift up and down so that the lock cylinder is inserted into the limiting plate and fixed.

[0046] In this embodiment, the lock cylinder feeding position is equipped with a vibrating plate and a straight vibrating track to feed the lock cylinder to the lock cylinder feeding position at the end of the straight vibrating track. It can also be fed manually with the straight vibrating track, which is not a limitation. When feeding the lock cylinder, its keyhole is facing upward so that the opening at the other end of the lock cylinder faces downward.

[0047] In addition, the first lifting device is a linear cylinder. A rotary motor is fixed to the end of the cylinder via a movable seat. A push rod is coaxially fixed to the output shaft of the rotary motor. The push rod is directly below the material loading position of the lock cylinder. The push rod is designed to be the diameter size that can be inserted into the lower opening of the lock cylinder. An opening for the push rod to pass through is opened on the bottom surface of the end of the linear vibrating track. Thus, when the cylinder drives the movable seat and the rotary motor to extend and retract, the push rod is inserted vertically into the opening below the lock cylinder to lift the lock cylinder to a high position, which facilitates the subsequent clamping and movement of the lock cylinder. During this process, if it is detected that the keyhole of the lock cylinder is not aligned with the limiting plate on the tooling, the rotary motor is used to rotate and correct it, so that the lock cylinder can be inserted into the limiting plate in the correct posture for limiting and fixing.

[0048] In this embodiment, the first gripper device is a finger cylinder, which has a pair of openable gripping fingers. The two gripping fingers are symmetrically provided with gripping grooves that are adapted to the shape of the lock cylinder, so that the gripping can be stably performed when gripping the lock cylinder. When the cylinder drives the motor to lift the lock cylinder to a high position, the gripping fingers of the finger cylinder move to both sides of the lock cylinder in an open posture. Then the gripping fingers close, the lock cylinder is inserted into the gripping groove, the cylinder drives the motor to retract, the push rod descends and disengages from the lock cylinder and returns to a position below the vertical vibration track to wait for the next lifting.

[0049] In this embodiment, the first swinging device is a rotary cylinder, which has a first output disk (not shown in the figure) that can rotate and swing in a circumferential direction. The first gripper device is fixed on the first output disk, and the range of the swinging of the finger cylinder driven by the first output disk is limited to the high position where the lock cylinder is lifted and gripped and the position directly above the limiting piece of the tooling. The first output disk corresponding to the above two positions rotates exactly 180°. During this process, the keyhole of the lock cylinder rotates and swings from the upward direction to the downward direction and the position directly above the limiting piece.

[0050] Furthermore, the first lifting device is also a linear cylinder, with the rotary cylinder fixed on the output shaft of the linear cylinder. Thus, the first lifting device drives the rotary cylinder, the finger cylinder, and the lock cylinder to rise and fall synchronously. After the lock cylinder moves to the top of the fixture, the first lifting device drives the lock cylinder to fall, allowing the keyhole of the lock cylinder to be smoothly inserted into the limiting plate. Finally, the finger cylinder releases the lock cylinder, and the first lifting device drives the finger cylinder and the rotary cylinder to rise. The rotary cylinder returns to its initial position, completing the loading process of the lock cylinder.

[0051] In addition, a limit block is installed directly above the loading position of the lock cylinder. The limit block is controlled to extend and retract by a linear stop cylinder. When the limit block extends to directly above the loading position of the lock cylinder, the lock cylinder moves under the action of the first lifting device to the position where the lock cylinder just contacts the limit block. This position is the high position of the lock cylinder after it is lifted. Then the limit block retracts to avoid affecting the movement trajectory of the swing cylinder and the finger cylinder.

[0052] Subsequently, the tooling, carrying the locked cylinder that has been positioned, enters the range of the central rotor assembly mechanism under the transmission of the conveyor device.

[0053] like Figure 8 As shown, the central rotor assembly mechanism is used to grip the central rotor above the lock cylinder on the tooling so that the rotor slot of the central rotor is engaged with the limiting plate.

[0054] Specifically, the central rotor assembly mechanism includes a central rotor loading position, a second lifting device, a first dual-axis transfer device, and a first rotating device. The second lifting device is used to lift individual central rotors one by one from the central rotor loading position. The first dual-axis transfer device is used to pick up the central rotor from the central rotor loading position and place it above the tooling at the corresponding position, so that the rotor slot of the central rotor is inserted into the limiting plate directly below it. The first rotating device is used to drive the central rotor to rotate and make the rotor slot and the limiting plate parallel and opposite to each other so as to achieve smooth insertion of the rotor slot and the limiting plate.

[0055] In this embodiment, the central rotor loading position is also loaded by a vibrating plate in conjunction with a linear vibrating track. The conveying end of the linear vibrating track forms the loading position of the central rotor. During the loading process of the central rotor, its rotor slot is in the positive downward direction, and the rotor insert is in the positive upward position. The second lifting device is a linear cylinder with a mold base fixed at its output end. A receiving slot that can just accommodate a single central rotor is formed on the side of the mold base close to the central rotor loading position. After the central rotor enters the receiving slot along the linear vibrating track, its upper rotor insert is located at the upper end and protrudes from the upper end surface of the mold base for easy gripping. The second lifting device rises and drives the central rotor to rise vertically.

[0056] In this embodiment, the first dual-axis transfer device includes a first transverse cylinder, a first lifting cylinder, and a first gripper cylinder. The first gripper cylinder has a pair of openable and closable first grippers. Symmetrical slots for inserting the rotor inserts are provided on the sides of the two first grippers that are close to each other. Both the first transverse cylinder and the first lifting cylinder are linear cylinders. The first transverse cylinder is horizontally placed on a corresponding support, and its output shaft is connected to a first sliding seat to drive the first sliding seat to move horizontally. The first lifting cylinder is disposed on the first sliding seat and distributed vertically. Another second sliding seat is disposed and connected to the first lifting cylinder. The vertical lifting of the second sliding seat is achieved by extending and retracting the first lifting cylinder. In addition, the first rotating device is a rotary cylinder and is fixed to the bottom of the second sliding seat. Its output end is fixed to the aforementioned first gripper cylinder, so that the pair of grippers of the first gripper cylinder... The claw is positioned vertically downwards, thus, through the first dual-axis transfer device, the first gripper cylinder can be driven to reciprocate between the loading position of the central rotor and the lock cylinder opening position on the tooling. When the second lifting device lifts the central rotor, the first gripper cylinder moves to the rotor insert position of the central rotor under the drive of the dual-axis transfer device. The two first grippers of the first gripper cylinder close, so that the rotor insert is embedded in the insert clamping groove. Then the second lifting device descends, and the first dual-axis transfer device moves the first gripper cylinder together with its fixed central rotor to directly above the lock cylinder on the tooling. At this time, the rotor groove below the central rotor is aligned with the limiting plate inside the lock cylinder opening. The first lifting cylinder drives the central rotor to descend, so that the rotor groove at its lower end is inserted into the limiting plate inside the lock cylinder opening. Finally, the two first grippers release, rise and reset, completing the loading, transfer and assembly process of the central rotor.

[0057] In the above process, the first rotating device is used to adjust the orientation of the first gripper so that the insert slot is aligned with the rotor insert of the center rotor, so that the first gripper cylinder can clamp the center rotor. At the same time, during the assembly of the center rotor, the orientation of the center rotor can also be rotated and adjusted so that the rotor slot of the center rotor is aligned with the limiting plate, so that the center rotor can be smoothly inserted into the limiting plate in the locking cylinder of the tooling.

[0058] Subsequently, the tooling, carrying the locked cylinder and central rotor that have been positioned, enters the range of the lock assembly mechanism under the transmission of the conveying device.

[0059] like Figure 9 , 10 As shown, the lock sleeve assembly mechanism is used to grab the lock sleeve with the rotating dial and to make the lock cavity slide down into the center rotor and lock cylinder in a vertical position. When the lock sleeve is inserted, the center rotor passes through the rotating dial to achieve synchronous rotation.

[0060] Specifically, the lock assembly mechanism includes a transfer fixture, a rotary wheel feeding device, a lock feeding device, a second swing device, a first pushing device, and a second dual-axis transfer device. The transfer fixture has a linear transfer groove and a first limiting groove located below the transfer groove and engaging with the protrusion and the meshing part. The lock feeding device is used to transfer the locks one by one onto the first limiting groove of the transfer fixture, so that the protrusion of the lock is engaged in the first limiting groove. The rotary wheel feeding device is used to transfer the rotary wheel one by one to the notch of the lock on the transfer fixture. The groove is filled in and the meshing part is engaged in the first limiting groove. The second swing device has a swing shaft and a swinger that drives the swing shaft to swing between horizontal and vertical postures. The end of the swing shaft has a positioning piece that can cooperate with the limiting of the rotating wheel. The first pushing device is used to push the assembled lock sleeve and rotating wheel along the transfer groove to the position where the swing shaft passes through the lock cavity and the rotating wheel. The second dual-axis transfer device is used to transfer the vertical lock sleeve and rotating wheel to the tooling above the corresponding position and insert them after the lock cavity and the limiting piece are aligned.

[0061] In this embodiment, the transfer fixture is generally elongated, with a relatively wide transfer groove first opened at its upper end. This groove is used to limit the movement of the main body of the lock sleeve and the main body of the rotating wheel. The center of the transfer groove is further recessed to form a first limiting groove. The width of the first limiting groove is adapted to the protrusion of the lock sleeve and the meshing part of the rotating wheel. When the lock sleeve is placed into the transfer fixture from above, its main body is limited by the transfer groove, and its protrusion is inserted into the first limiting groove. At this time, the notch of the lock sleeve is located on the upper side of the transfer groove, and the rotating wheel can be inserted into the lock sleeve from the notch. The main body of the rotating wheel is also limited by the transfer groove, and its lower meshing part is correspondingly placed into the first limiting groove. Ultimately, the lock sleeve and the rotating wheel maintain a consistent posture on the transfer fixture.

[0062] In addition, in order to achieve synchronous movement of the locking sleeve and the rotating dial within the transfer slot, the first pushing device is a linear cylinder, and a U-shaped actuating plate is fixed to the end of its output shaft. The actuating plate has an actuating part that is adapted to the first limiting slot. In order to cooperate with the actuating plate, the transfer slot and the first limiting slot are both through on both sides along the length direction. The initial position of the actuating plate is located on one side of the transfer slot. Thus, when the first pushing device extends or retracts, the actuating part of the actuating plate moves along the first limiting slot, synchronously moving the locking sleeve and the rotating dial to the other side along the extension direction of the transfer slot.

[0063] In this embodiment, the swing device is a rotary cylinder, and the swing shaft is fixed on the output plate of the rotary cylinder. In the initial position, the swing shaft is located in the horizontal direction parallel to the transfer slot, and the swing shaft is located on one side of the transfer slot. The positioning piece at the end of the swing shaft is directly opposite the insert slot of the rotating wheel. When the first pushing device drives the locking sleeve and the rotating wheel to move toward the swing shaft, the positioning piece sequentially passes into the locking cavity of the locking sleeve and the insert slot of the rotating wheel. At this time, the locking sleeve and the rotating wheel are integrally limited on the swing shaft. Under the drive of the swing device, it is rotated and swung from the horizontal position to a vertical position of 90° to facilitate subsequent transfer.

[0064] In this embodiment, the second dual-axis transfer device includes a second transverse cylinder, a second lifting cylinder, and a second gripper cylinder. The second lifting cylinder and the second transverse cylinder are both linear cylinders. The second gripper cylinder is a gripper-type cylinder with a pair of second grippers. The sides of the two second grippers that are close to each other are recessed inward to form a slot. The opening of the slot forms four contact slopes to achieve contact with the outer circumferential arc sidewall of the lock sleeve body. When the lock sleeve is inserted, the circumferential sidewall of the lock sleeve body is clamped between the four contact slopes. The protrusion of the lock sleeve extends along the gap between the second grippers and is limited and fixed by the sidewall of the second grippers, so that the lock sleeve and the rotating dial maintain a vertical and stable posture on the second gripper cylinder. At this time, the lock cavity of the lock sleeve is distributed in the vertical direction. The second gripper cylinder is vertically fixed to the output shaft of the second lifting cylinder, and the second lifting cylinder is vertically fixed to the output shaft of the second transverse cylinder. The second transverse cylinder is horizontally fixed to the corresponding bracket. When the second transverse cylinder extends or retracts, the second lifting cylinder and the second gripper cylinder reciprocate between directly above the fixture and the vertical swing position of the swing shaft. When the second lifting cylinder extends or retracts, the second gripper cylinder moves to the vertical swing position of the swing shaft or to the position of the locking cylinder and the central rotor of the fixture. Thus, when the locking sleeve and the rotating dial are driven by the swing shaft and the swinging device to rotate... When rotated to the vertical position, the second gripper cylinder opens and clamps and fixes the outer wall of the lock sleeve and the rotating wheel. Then, driven by the second transverse cylinder and the second lifting cylinder, the lock sleeve and the rotating wheel are moved to the top of the fixture and inserted vertically downward along the direction of the lock cylinder and the central rotor, so that the lock cylinder and the central rotor smoothly pass into the lock sleeve along one side of the lock cavity. At this time, the rotor plate of the central rotor just passes into the plate slot of the rotating wheel, and the protrusion of the lock sleeve just passes into the limiting area between the two limiting shafts and is stably limited in the positive fixed position of the fixture, thus completing the assembly of the lock sleeve and the rotating wheel.

[0065] In addition, combined Figure 9 To facilitate the feeding of the rotating wheel and the lock sleeve, the rotating wheel is fed by a vibratory feeder in conjunction with a linear vibrating track, while the lock sleeve is fed manually or by a conveyor belt. The rotating wheel is conveyed to the end of the linear vibrating track with its meshing part vertically downward, and then gripped by the corresponding first finger cylinder and moved into the notch groove of the lock sleeve on the transfer fixture. The lock sleeve is then gripped by the corresponding second finger cylinder. The two third claws of the second finger cylinder have a pair of downwardly extending clamping plates. The two clamping plates protrude in a direction away from each other to form a cylindrical clamping block that adapts to the lock cavity. Thus, the two clamping plates pass through the notch groove of the lock sleeve. When they open, the two clamping blocks pass into the lock cavities on both sides respectively. At this time, the lock sleeve is raised, and under its own weight, it automatically rotates along the arc surface of the clamping block to a vertical position with the protrusion facing downward, so as to smoothly move the lock sleeve onto the transfer fixture, so that its protrusion smoothly inserts into the first limiting groove when the lock sleeve descends.

[0066] In addition, to facilitate the transfer of the lock sleeve and the rotating wheel, the rotating wheel feeding device and the lock sleeve feeding device are integrated into a fourth dual-axis moving device. This device uses two cooperating horizontal and vertical cylinders to drive a linkage plate to move in the horizontal and vertical directions. The finger cylinders used to clamp the lock sleeve and the rotating wheel are simultaneously fixed on the linkage plate with consistent spacing. The distance between the rotating wheel feeding position and the transfer fixture, as well as the distance between the lock sleeve feeding position and the transfer fixture, are consistent with the distance between the two finger cylinders on the linkage plate. This enables the alternating gripping and feeding of the lock sleeve and the rotating wheel.

[0067] In addition, the locking sleeve and rotating wheel can also be fed by a material tray. The material tray is designed with a groove that fits into the locking sleeve or rotating wheel, so that the locking sleeve or rotating wheel is arranged in the material tray with the protrusion or engagement part facing down. Then, the locking sleeve and rotating wheel are placed into the transfer groove and the first limiting groove of the transfer fixture by a robotic arm, which can also complete the convenient feeding of the locking sleeve and rotating wheel.

[0068] In this embodiment, the first finger cylinder used to grip the rotating dial has gripping grooves (not shown in the figure) on both of its jaws that are adapted to the arc-shaped outer wall of the rotating dial, thereby facilitating stable gripping of the rotating dial.

[0069] Through the above process, the lock sleeve and rotating dial are assembled onto the lock cylinder and central rotor on the tooling. Then, the tooling is conveyed by the conveying device to the position of the first snap ring assembly mechanism for snap ring assembly.

[0070] like Figure 11 As shown, the first snap ring assembly mechanism is used to fit the snap ring into the snap ring groove located on the notch groove of the lock cylinder and press it to limit the axial movement of the lock cylinder.

[0071] Specifically, in this embodiment, both the first and second snap ring assembly mechanisms include a snap ring loading position, a third lifting device, a snap ring clamp, a double-stroke linear moving device, a compression spring device, and a second pushing device. The third lifting device is used to lift the snap rings one by one from the snap ring loading position. The snap ring clamp has a clamping structure that can fix the snap ring from the side so that the snap ring opening faces away from the snap ring clamp. The double-stroke linear moving device is used to drive the snap ring clamp to reciprocate between the initial position, the snap ring loading position, and the snap ring loading position on the tooling. The compression spring device has a pair of rivet claws for riveting the snap rings. The second pushing device is used to push the compression spring device to the snap ring loading position.

[0072] In this embodiment, the snap ring is fed by a vibratory feeder in conjunction with a linear vibratory track. The end of the conveying direction of the linear vibratory track is the snap ring feeding position. The third lifting device is a linear cylinder, which is set vertically below the end of the conveying direction of the linear vibratory track. The end of its output shaft is provided with a cylindrical sleeve. The top of the sleeve forms a socket groove whose shape is adapted to the opening area inside the snap ring. Its initial position is set below the linear vibratory track. When the snap ring is conveyed to the snap ring feeding position, the third lifting device rises, and the opening area inside the snap ring passes through the sleeve and rises to a higher position with the sleeve, which is convenient for subsequent removal.

[0073] To facilitate the removal and repositioning of the retaining ring, the retaining ring fixture is designed as a long plate, including a base plate and a cover plate covering the upper end of the base plate. The front ends of both the base plate and the cover plate are recessed inward to form arc-shaped openings. Within these arc-shaped openings are suction grooves that conform to the shape of the retaining ring and precisely accommodate its edge. The suction grooves and the retaining ring are fixed together by magnetic attraction, vacuum adsorption, or elastic compression to prevent the retaining ring from falling out during movement. In this embodiment, magnetic attraction is used. Therefore, when the retaining ring fixture moves to the sleeve shaft side, the edge of the retaining ring on the sleeve shaft is precisely engaged in the suction groove, and under the magnetic attraction, the retaining ring is confined within the suction groove. Subsequently, the third lifting device descends, causing the sleeve shaft to move downwards away from the opening area of ​​the retaining ring, returning to its initial position below the vertical vibration track. Afterwards, the retaining ring fixture can move the retaining ring to the tooling side for the retaining ring assembly process.

[0074] To achieve the removal and movement of the snap ring, in this embodiment, the double-stroke linear movement device includes two cooperating first telescopic cylinders and a second telescopic cylinder. The extension and retraction directions of the second telescopic cylinder and the first telescopic cylinder are parallel to each other, and the second telescopic cylinder is fixed on the output shaft of the first telescopic cylinder. The snap ring clamp is fixed on the output shaft of the second telescopic cylinder. Thus, through the extension and retraction of the first telescopic cylinder and the second telescopic cylinder, the snap ring clamp can obtain two segments of linear stroke, allowing it to reciprocate between the initial position, the snap ring loading position of the first segment, and the tooling position of the second segment, thereby realizing the removal and movement of the snap ring. When the snap ring clamp extends in two segments under the drive of the double-stroke linear movement device, the opening area of ​​the snap ring is just inserted into the notch groove of the locking sleeve on the tooling and fitted into the snap ring groove at the upper end of the lock cylinder. At this time, the snap ring is still in an unriveted state and cannot limit the lock cylinder.

[0075] To achieve the riveting of the retaining ring, a compression spring device and a second pushing device are provided on the side of the tooling away from the retaining ring fixture. The second pushing device is a linear cylinder whose extension and retraction direction is towards or away from the fixture. The compression spring device is a claw-type finger cylinder with a pair of rivet claws. The side of the two rivet claws that are close to each other protrudes to form an extension piece. The end of the extension piece forms an arc-shaped pressing groove that conforms to the arc surface of the notch. The finger cylinder is fixed on the output shaft of the second pushing device. When the second pushing device extends, the extension pieces on the two claws are located on both sides of the notch. When the two claws close, their arc-shaped pressing grooves just contact the edge of the retaining ring. If they continue to close inward, the retaining ring will deform and be riveted into the snap ring groove of the lock cylinder.

[0076] In this embodiment, in order to cooperate with the compression spring device, the snap ring clamp is also provided with an auxiliary fixing device. The auxiliary fixing device has an auxiliary pressure block that can be linearly extended and retracted. The auxiliary pressure block is slidably disposed on one side of the clamping structure along the sliding direction of the snap ring clamp, and is used to press the snap ring in the extended state to cooperate with the rivet claw to rivet the snap ring.

[0077] Specifically, the auxiliary pressure block is fixed on the output shaft of an auxiliary cylinder, and the auxiliary pressure block is inserted into one side of the suction groove. When the auxiliary cylinder extends, it causes the auxiliary pressure block to protrude slightly out of the suction groove, thereby pressing against the snap ring. In conjunction with the spring compression device, the snap ring is stably riveted, so that it is smoothly fixed in the snap ring groove of the lock cylinder, thereby achieving axial positioning of the lock cylinder on the lock sleeve. At this time, moving the lock sleeve can lift the installed parts as a whole.

[0078] like Figure 12 As shown, the finger twister feeding mechanism is used to grab the finger twister to the reverse fixed position so that the knob of the finger twister is limited in the first limiting groove and the inner cavity opening of the finger twister faces upward.

[0079] In this embodiment, the finger twister is manually placed on the feeding conveyor belt and transported in a vertical posture with the knob in contact with the surface of the feeding conveyor belt and the inner cavity facing upward to the finger twister feeding position. The finger twister feeding mechanism includes a finger twister feeding position, a third dual-axis transfer device and a second rotation device. The third dual-axis transfer device is used to transfer the finger twister from the finger twister feeding position to the upper end of the first limiting groove of the corresponding position tool and insert the knob of the finger twister into the first limiting groove. The second rotation device is used to rotate the finger twister to adjust the knob posture so that the knob can be smoothly inserted into the first limiting groove.

[0080] The third dual-axis transfer device includes a third transverse cylinder and a third lifting cylinder. The third transverse cylinder is horizontally positioned via a corresponding bracket, and the end of its output shaft is fixed to the third lifting cylinder. The third lifting cylinder is fixed in a vertical position, and its output shaft extends and retracts downward. The second rotating device is a rotating cylinder, fixed to the end of the output shaft of the third lifting cylinder. A third finger cylinder is provided on the output plate of the second rotating device. The third finger cylinder has a pair of fourth jaws, and a transfer component is clamped and fixed between the two fourth jaws. The lower end of the transfer component has a transfer structure that can be fitted with the inner cavity opening. The transfer structure is located in the third dual-axis transfer device. Driven by the picking device, it reciprocates between the finger rotary feeder and the tooling. When the finger rotary feeder moves to the feeder feeder position along the feeding conveyor belt, the picking component descends to the opening position of the finger rotary feeder's inner cavity, and the picking structure of the picking component penetrates into the inner cavity and is connected and fixed to the finger rotary feeder. Then, driven by the third dual-axis picking device, the picking component moves to the tooling, so that the finger rotary feeder is facing the first limiting groove on the reverse fixed position. The second rotating device adjusts the attitude of the finger rotary feeder so that its knob is facing the first limiting groove. Finally, the knob is placed into the first limiting groove, so that the finger rotary feeder completes the feeding process on the tooling.

[0081] like Figure 13 As shown, the spring feeding mechanism is used to vertically insert the spring into the inner cavity along the inner cavity opening at the end of the finger twister.

[0082] In this embodiment, the spring feeding mechanism includes a spring feeding position, a spring clamp, a third pushing device, and a third swinging device. The spring clamp includes pressure claws on both sides and a positioning shaft located in the middle of the pressure claws. The positioning shaft is used to fit a single spring in the spring feeding position, and the pressure claws are used to clamp the spring on the positioning shaft. The third swinging device is used to swing the positioning shaft along a circumferential path to a position facing the opening of the inner cavity of the finger twister. The third pushing device is used to telescopically move the spring clamp along a straight line so that the positioning shaft can approach the spring feeding position and the inner cavity opening.

[0083] The springs are stably fed through a combination of a vibratory feeder and a linear vibrating track, with a spring feeding position formed at the end of the linear vibrating track. The spring clamp is a claw-type finger cylinder with a pair of pressure claws and a positioning shaft parallel to and opposite the linear vibrating track between the pressure claws. After the spring is transmitted to the end of the linear vibrating track, it is pushed outward by the subsequent spring, causing it to pass into the positioning shaft. At this point, the pressure claws simply need to close to clamp and fix the spring.

[0084] In this embodiment, the third swinging device is a rotary cylinder. A third telescopic cylinder (i.e., a third pushing device) is fixed on the output disk of the rotary cylinder. The spring clamp is fixed to the end of the output shaft of the third telescopic cylinder, and the telescopic direction of the third telescopic cylinder is along the axial direction of the output disk. In the initial state, the spring clamp is in a horizontal state where the positioning shaft is parallel to the linear vibration track. After the third swinging device drives the spring clamp to swing, it is vertically oriented directly above the tooling, and at this time, the positioning shaft is opposite to the inner cavity opening of the finger twister on the tooling. After the third telescopic cylinder extends, it drives the spring clamp and the spring to move downward together until the positioning shaft contacts the inner cavity opening of the finger twister. Then the pressure claw is released, and the spring slides down the positioning shaft into the inner cavity of the finger twister under its own weight. Finally, the third telescopic cylinder retracts, and the third swinging device drives the spring clamp to return to its original position, completing the spring loading process.

[0085] Subsequently, the tooling drives the lock cylinder, lock shell, center rotor, rotating wheel, snap ring, and the finger screw and spring located in the forward fixed position to be transported to the position of the flipping mechanism by the conveying device.

[0086] like Figure 14 As shown, the flipping mechanism is used to move the lock sleeve, lock cylinder rotating wheel and central rotor as a whole out of the limiting plate after the upper limit of the forward fixed position. After vertical flipping, the other lock cavity opening of the lock sleeve is aligned with the inner cavity opening of the finger twister on the reverse fixed position and inserted to realize the assembly of the finger twister.

[0087] Specifically, the flipping mechanism includes a fourth swinging device, a second gripper device, and a second lifting device. The second gripper device has a pair of fifth grippers for clamping the outer wall of the lock sleeve. The second lifting device is used to drive the second gripper device to move vertically up and down. The fourth swinging device is used to drive the second gripper device to swing along a circumferential path to achieve the flipping of the lock sleeve in the vertical direction, thereby transferring it from the forward fixed position to the reverse fixed position.

[0088] In this embodiment, the fourth swinging device is a rotary cylinder, and a second gripper device is fixed on its output plate. The second gripper device is a finger cylinder. The second gripper device is eccentrically positioned with the center of the rotary cylinder output plate. Driven by the rotary cylinder, it is tilted 180° in the vertical direction, so that the item held by the second gripper device can be vertically flipped 180°. The purpose of this structure is to use the second gripper to hold the lock cylinder, central rotor, rotating wheel and retaining spring that are fixed in the lower lock cavity of the lock sleeve, and flip them together with the lock sleeve vertically to the position of the upper lock cavity of the lock sleeve. So that the lower lock cavity of the lock sleeve is facing downwards at this time, and the finger twister and spring can continue to be accommodated.

[0089] During this process, when the fourth swinging device drives the second gripper device to swing, its two swinging points are located at the locking sleeve position on the positive fixed position and the finger rotating position on the reverse fixed position, respectively.

[0090] To further facilitate the reversing process of the lock sleeve and prevent the tooling from affecting the reversing process, the second lifting device is a linear rodless cylinder, installed vertically and fixed by a corresponding bracket. Its output shaft faces vertically upward. The fourth swing device is fixed to the output shaft of the second lifting device, so that the second lifting device drives the fourth swing device and the second gripper to achieve synchronous lifting. After the second gripper clamps the outer wall of the lock sleeve, the second lifting device lifts it up so that the lock cylinder is removed from the range of the limiting plate. Then, the fourth swing device drives the lock sleeve to rotate 180° along the circumferential path, so that its originally upward-opening lock cavity becomes vertically downward-opening and directly facing the first limiting groove on the reverse fixed position. At this time, the lock cavity and the inner cavity opening at the upper end of the finger turner are also facing each other. The second lifting device retracts, so that the entire lock sleeve moves down and the upper end of the finger turner enters the lock cavity at the lower end of the lock sleeve, completing the initial assembly of the finger turner. Finally, the second gripper releases the lock sleeve and rises again to return to its original position under the action of the fourth swing device and the second lifting device.

[0091] In the above process, in order to enhance the clamping effect on the outer wall of the lock sleeve, the second gripper device has a pair of fifth grippers, and an arc-shaped clamping groove adapted to the main body of the lock sleeve is opened on the side of the two fifth grippers that are close to each other. The two sides of the arc-shaped clamping groove and the side wall of the gripper form a flat contact surface. Thus, when the gripper clamps the lock sleeve, the main body of the lock sleeve is clamped and limited by the clamping grooves on both sides, and the protrusion of the lock sleeve is also stably limited by the restriction of the contact surface on both sides. This makes the lock sleeve maintain a stable orientation during the entire flipping and swinging process, which is convenient for insertion and engagement with the finger twister.

[0092] After the above process is completed, the tooling integrates the finger turner, spring, rotating wheel, center rotor, lock cylinder and lock sleeve in the reverse fixed position. The finger turner is still not limited. Under the transmission of the transmission device, the tooling continues to be transmitted to the second snap ring assembly mechanism.

[0093] Combination Figure 4 and Figure 11 The second snap ring assembly mechanism is used to fit the snap ring into the snap ring groove located on the notch groove of the finger turner and press it to limit the axial position of the finger turner. In this embodiment, the structure of the second snap ring assembly mechanism is completely the same as that of the first snap ring assembly mechanism. The difference is that the assembly height of the snap ring is slightly different. Therefore, by adjusting the height of the second snap ring assembly mechanism, the second snap ring can be successfully assembled, so that the finger turner is axially limited on the lock sleeve, and the overall assembly process of the lock cylinder is completed.

[0094] It also includes a feeding mechanism, which includes a fourth dual-axis device, a clamping device, and a lock cylinder feeding position. The clamping device is used to clamp the assembled outer wall of the lock sleeve. The fourth dual-axis device is used to drive the clamping device to move on the horizontal and vertical axes so that the clamping device moves between the tooling and the lock cylinder feeding position in the corresponding position. The lock cylinder feeding position is connected to the feeding conveyor belt or the finished product container.

[0095] Specifically, such as Figure 15 The diagram shows the lock cylinder feeding mechanism. It uses a fourth dual-axis device, which is the same as the aforementioned dual-axis transfer device. The clamping device is a clamping finger cylinder with a clamping groove that is adapted to the shape of the lock sleeve. In conjunction with the corresponding feeding conveyor belt, the assembled lock cylinder is clamped and transferred to the feeding conveyor belt for conveying. The tooling is then cyclically conveyed back to the initial position for the next round of lock cylinder assembly.

[0096] Alternatively, the feeding conveyor belt can be replaced with a finished product container, such as a feeding tray, to achieve unified collection and feeding of assembled finished lock cylinders.

[0097] like Figure 16 As shown, in this embodiment, the conveying device cyclically conveys along a U-shaped rotary path on a vertical plane, including an upper conveying path and a lower conveying path with opposite conveying directions. An upward pushing cylinder is installed at the initial position of the upper conveying path to push the tooling into the upper conveying path one by one. A downward pushing cylinder is installed at the initial position of the lower conveying path to push the tooling into the lower conveying path one by one. Elevator cylinders are installed at the initial positions of both the upper and lower conveying paths. Each elevator cylinder includes a linear cylinder and an elevator seat. The elevator seat includes a support capable of carrying the tooling. In the lifting elevator shaft, when the tooling gradually moves along the lower conveyor path to the initial position of the upper conveyor path at its end, it enters the elevator shaft on that side. The elevator cylinder drives the elevator shaft to rise, bringing it to the initial position of the upper conveyor path. Then, under the action of the upper push cylinder, it enters the upper conveyor path. Similarly, when the tooling that has been conveyed to the end of the upper conveyor path enters the elevator shaft on that side, the elevator cylinder drives the elevator shaft to descend, bringing it to the initial position of the lower conveyor path. Then, under the action of the lower push cylinder, it enters the lower conveyor path, thus realizing the cyclical conveying of the tooling.

[0098] In addition, on the upper conveying path, the tooling is driven in a cyclic manner by the upper push cylinder, which pushes the tooling one by one into the upper conveying path. The next tooling continues to move forward under the push of the previous tooling. That is, the upper push cylinder is used as the power source for continuous cyclic driving.

[0099] To reduce the amount of tooling used, the lower conveyor path is driven by the lower conveyor belt. Therefore, a single tool can be conveyed on the lower conveyor belt. As long as the time interval is taken into account, the upper conveyor belt can always be continuously covered with tooling to achieve the cyclical conveying process of tooling.

[0100] In particular, all dual-axis transfer devices in this embodiment, in addition to the linear cylinder drive method described above, can also achieve dual-axis movement on the horizontal and vertical axes through the cooperation of a motor screw structure and the cooperation of a motor screw structure and a cylinder, without any restrictions.

[0101] The beneficial effects of this utility model are as follows:

[0102] This utility model uses a fixture with a forward fixed position and a reverse fixed position to fix the lock cylinder and the finger turner at both ends of the lock cylinder respectively. Based on the lock cylinder and the finger turner, the central rotor and spring are assembled. Then, the lock sleeve and the rotating wheel are inserted into the forward fixed position to complete the assembly with the lock cylinder and the central rotor. Finally, the lock sleeve is flipped to the reverse fixed position so that the lock sleeve and the finger turner are assembled. Through the above assembly process, the assembly process of a single-opening lock cylinder can be realized conveniently and efficiently, solving the assembly problem of single-opening lock cylinders.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
