[0066] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0067] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there may also be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time.

[0068] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0069] As Figures 1 to 20 shown, the present application provides a cylinder assembly machine 100 for assembling a cylinder, including a cylinder cap acquisition mechanism 30; the cylinder cap acquisition mechanism 30 is configured to be adapted to align the keyhole 111 of the cylinder cap 11 in a set direction and place it on the cylinder body 12; the cylinder cap acquisition mechanism 30 includes a positioning assembly 304 and a resetting device 32, the positioning assembly 304 includes a positioning member 35 and a first elastic member 34, the top of the positioning member 35 is configured to be adapted to insert into the keyhole 111, and the first elastic member 34 is configured to apply a force to the positioning member 35 in a direction approaching the cylinder cap 11; the resetting device 32 is configured to be able to drive the cylinder cap 11 to rotate so that its keyhole 111 rotates to a predetermined position, at which the positioning member 35 moves upward under the action of the first elastic member 34 and inserts into the keyhole 111 to limit the continuous rotation of the cylinder cap 11 and thus align its keyhole 111 in a set direction.

[0070] The lock core cap acquisition mechanism 30 acquires the lock core cap 11 and aligns the keyhole 111 of the lock core cap 11 to a set direction. When the lock core cap acquisition mechanism 30 aligns the keyhole 111 of the lock core cap 11 to the set direction: the alignment device 32 drives the lock core cap 11 to rotate; when the keyhole 111 of the lock core cap 11 rotates to a predetermined position, the positioning member 35 extends into the keyhole 111 of the lock core cap 11 under the drive of the first elastic member 34 to limit the rotation of the lock core cap 11, thereby aligning the keyhole 111 to the set direction, facilitating the operation of the next process of the lock core cap 11, and facilitating the assembly of the lock core cap 11. Among them, when the alignment device 32 does not drive the lock core cap 11, the positioning member 35 may also be located in the keyhole 111. At this time, the alignment device 32 does not need to drive the lock core cap 11 to rotate.

[0071] In this embodiment, as Figure 3 shown, the lock core body 12 has a lock core hole 121. When the lock core cap 11 is riveted to the lock core body 12, the position of the keyhole 111 corresponds to the position of the lock core hole 121 so that the key can pass through the keyhole 111 and the lock core hole 121 in sequence. Among them, the shape of the keyhole 111 is adjusted according to the lock core hole 121 on the lock core body 12, which will not be further elaborated here. The lock core cap 11 is generally in a disc-shaped structure, and the lock core cap 11 has an axis in space; the lock core cap 11 has a main body portion 114 and a flanging 115 located on the outer periphery of the main body portion 114. The lock core cap 11 has a first side 112 and a second side 113 arranged opposite to each other; along the axis of the lock core cap 11, the first side 112 and the second side 113 are located on both sides of the lock core cap 11. Among them, the rotation axis of the lock core cap 11 is parallel to the axis of the lock core cap 11. The lock core body 12 is generally in a columnar structure; the lock core body 12 has a top and a bottom arranged opposite to each other; the top of the lock core body 12 has a riveting convex ring 122. When the lock core cap 11 is located on the top of the lock core body 12, the main body portion 114 is located on the top of the lock core body 12, and the flanging 115 is located outside the riveting convex ring 122; when riveting the lock core cap 11 and the lock core body 12, the lock core riveting structure 70 deforms the flanging 115 and rivets it to the riveting convex ring 122.

[0072] In this embodiment, as Figures 1 to 2 shown, the lock core assembly machine 100 further includes a frame 20, and the lock core assembly machine 100 further includes a lock core body acquisition mechanism 80 and a lock core riveting structure 70; the lock core body acquisition mechanism 80 acquires the lock core body 12; the lock core cap 11 is placed on the lock core body 12, and then riveted by the lock core riveting structure 70 to form the lock core 10. The lock core body acquisition mechanism 80, the lock core cap acquisition mechanism 30, and the lock core riveting structure 70 are all arranged on the frame 20. The structure of the frame 20 is not strictly limited, as long as it can support the lock core body acquisition mechanism 80, the lock core cap acquisition mechanism 30, and the lock core riveting structure 70, which will not be further elaborated here; for example, the shape of the frame 20 can be a frame structure.

[0073] In this embodiment, if Figures 1 to 20 As shown, the lock core assembly machine 100 further includes a fixture 40 for carrying the lock core body 12; there is no strict restriction on the structure of the fixture 40, and the fixture 40 can be fixed to the lock core body 12. The lock core assembly machine 100 further includes a turntable 41, which is rotatably mounted on the frame 20; there are multiple fixtures 40, and multiple fixtures 40 are arranged at intervals around the circumference of the turntable 41; the multiple fixtures 40 can be switched at various stations during the rotation of the turntable 41, so that the lock core assembly machine 100 can assemble various components of the lock core 10. The number of the fixtures 40 is set according to the stations where the components in the lock core 10 need to be assembled; for example, the station for obtaining the lock core body 12, the station for obtaining the lock core cap 11, the station for riveting the lock core 10, and the station for unloading the lock core 10; wherein the lock core body acquisition mechanism 80 is located at the station for obtaining the lock core body 12, the lock core cap acquisition mechanism 30 is located at the station for obtaining the lock core cap 11, and the lock core riveting structure 70 is located at the station for riveting the lock core 10. The turntable 41 can be driven by a drive motor; the drive motor is installed on the frame 20, and the output shaft of the drive motor is connected to the turntable 41. When the lock core assembly machine 100 is in the installed state, the turntable 41 rotates approximately around the vertical axis.

[0074] In this embodiment, if Figure 1 , Figure 2 and Figure 13 As shown, the lock core body acquisition mechanism 80 includes a first clamp 81, and the first clamp 81 is used to place the lock core body 12 in the fixture 40. The structure of the first clamp 81 can be a prior art; for example, a pneumatic clamp. The lock core body acquisition mechanism 80 also includes a second conveyor line 82, and the second conveyor line 82 is used to convey the lock core body 12. The first clamp 81 can grab the lock core body 12 on the second conveyor line 82 and place the lock core body 12 in the fixture 40. The second conveyor line 82 can adopt the prior art, which will not be further described here.

[0075] In this embodiment, if Figures 3 to 8 As shown, the placement device 32 abuts against the first side 112 of the lock core cap 11; when the positioning member 35 does not extend into the key hole 111 of the lock core cap 11, the positioning member 35 can abut against the second side 113 of the lock core cap 11; so as to ensure the force balance of the lock core cap 11 and enable the lock core cap 11 to rotate stably. When the lock core cap acquisition mechanism 30 locates the position of the lock core cap 11, the placement device 32 first abuts against the first side 112 of the lock core cap 11, and then the first elastic member 34 drives the positioning member 35 to abut against the second side 113 of the lock core cap 11; when the key hole 111 of the lock core cap 11 rotates to a predetermined position, the positioning member 35 extends into the key hole 111.

[0076] In this embodiment, if Figures 3 to 8As shown, the placement device 32 drives the lock core cap 11 to rotate more than one full circle to ensure that the keyhole 111 rotates to a predetermined position, ensuring that the position of the keyhole 111 corresponds to the position of the positioning member 35 so that the positioning member 35 can extend into the keyhole 111. The placement device 32 drives the lock core cap 11 to rotate through friction with the lock core cap 11; the transmission components between the placement device 32 and the lock core cap 11 can be reduced to simplify the structure of the lock core cap acquisition mechanism 30. The placement device 32 includes a base 321 and a driving portion 322. The driving portion 322 is movably coupled to the base 321 through a second elastic member 323. The driving portion 322 is used to drive the lock core cap 11 to rotate; when the driving portion 322 abuts against the lock core cap 11, the second elastic member 323 provides a certain buffer to the driving portion 322 to prevent the driving portion 322 from damaging the lock core cap 11. The base 321 has a first sliding groove 324 and a limiting groove 327; the driving portion 322 can extend into the first sliding groove 324 and slide along the first sliding groove 324; one end of the second elastic member 323 abuts against the driving portion 322, and the other end abuts against the bottom of the first sliding groove 324; the driving portion 322 has a pin shaft 328 that cooperates with the limiting groove 327, which can limit the relative rotation between the driving portion 322 and the base 321 and can also prevent the driving portion 322 from detaching from the first sliding groove 324. The limiting groove 327 has a certain length so that the pin shaft 328 can slide within the limiting groove 327, thereby enabling the driving portion 322 to slide within the first sliding groove 324 to prevent the driving portion 322 from detaching from the base 321. The driving portion 322 is made of rubber; the rubber portion of the driving portion 322 abuts against the lock core cap 11 to reduce damage to the lock core cap 11 and can also increase the friction between the driving portion 322 and the lock core cap 11. Among them, the second elastic member 323 is a spring.

[0077] In this embodiment, as Figures 3 to 8 shown, the structures of the base 321 and the driving portion 322 are not strictly limited; for example, the base 321 has a cylindrical structure and the driving portion 322 has a rod-shaped structure. The driving portion 322 includes a first portion 325 and a second portion 326. The first portion 325 can extend into the first sliding groove 324 and slide along the first sliding groove 324; one end of the second elastic member 323 abuts against the first portion 325, and the other end abuts against the bottom of the first sliding groove 324; the first portion 325 has a mounting groove for mounting the second portion 326; the second portion 326 is used to abut against the lock core cap 11 and drive the lock core cap 11 to rotate. Among them, the pin shaft 328 is installed on the first portion 325; the second portion 326 is made of rubber.

[0078] In this embodiment, as Figures 3 to 8As shown, the lock core cap acquisition mechanism 30 also includes a driving assembly 33, which is used to drive the driving part 322 to move along the first direction to abut against the lock core cap 11, and drive the driving part 322 to rotate around the set axis. The driving assembly 33 includes a first driving member 331 and a second driving member 332. The first driving member 331 is used to drive the placement device 32 to move along the first direction to abut against the lock core cap 11; the second driving member 332 is used to drive the placement device 32 to rotate around the set axis. The first driving member 331 drives the placement device 32 to abut against the lock core cap 11, and then the second driving member 332 drives the placement device 32 to rotate around the set axis; the first direction is parallel to the set axis. The first driving member 331 is installed on the frame 20; the first driving member 331 is a cylinder; the second driving member 332 is a motor; the piston rod of the first driving member 331 is connected to the second driving member 332, and the base 321 is connected to the output shaft of the second driving member 332.

[0079] In this embodiment, if Figure 4 , Figure 5 and Figure 9 As shown, the positioning member 35 is generally in a rod-shaped structure; the outer contour of the positioning member 35 is generally the same as the shape of the keyhole 111, so that when the positioning member 35 is inserted into the keyhole 111, the positioning member 35 can limit the rotation of the lock core cap 11; wherein, the outer contour of the positioning member 35 and the shape of the keyhole 111 are non-circular, such as a strip structure. The positioning member 35 can move along the first direction driven by the first elastic member 34 to extend into the keyhole 111.

[0080] In this embodiment, if Figure 4 , Figure 5 and Figure 9 As shown, the positioning assembly 304 further includes a driving member 36, which drives the positioning member 35 to move from the first position to the second position; in the first position, the positioning member 35 avoids the lock core cap 11; in the second position, the positioning member 35 presses against the lock core cap 11 or extends into the key hole 111. When the positioning member 35 is in the first position, the positioning member 35 and the driving member 36 both avoid the lock core cap 11, so that the lock core cap 11 moves to the top of the positioning member 35; then the placement device 32 abuts against the second side 113 of the lock core cap 11; when the driving member 36 drives the positioning member 35 to move to the second position, the positioning member 35 abuts against the first side 112 of the lock core cap 11, and the first elastic member 34 is in a compressed state. When the placement device 32 drives the lock core cap 11 to rotate to a predetermined position, the first elastic member 34 drives the positioning member 35 to extend into the key hole 111. Of course, when the key hole 111 of the lock core cap 11 is in the set direction, when the driving component 36 drives the positioning member 35 to move to the second position, the positioning member 35 will directly extend into the key hole 111 .

[0081] In this embodiment, ifFigure 4 , Figure 5 and Figure 9 As shown in Figure 9 , the driving member 36 has a first sliding hole 361 for the positioning member 35 to slide, so as to be able to define the movement path of the positioning member 35. One end of the first elastic member 34 is connected to the positioning member 35, and the other end is connected to the driving member 36. Among them, the first elastic member 34 is a spring; the driving member 36 has a fixed shaft 362, the positioning member 35 has a fitting groove 351 for the fixed shaft 362 to pass through, one end of the first elastic member 34 is connected to the fixed shaft 362, and the other end abuts against the wall of the fitting groove 351. Among them, the lock core cap acquisition mechanism 30 further includes a third driving member 37 for driving the driving member 36 to slide, and the third driving member 37 is installed on the frame 20; the third driving member 37 can be a cylinder.

[0082] In this embodiment, as Figure 4 , Figure 5 and Figure 9 As shown in Figure 9 , the lock core cap acquisition mechanism 30 further includes a supporting base 31 for supporting the lock core cap 11 and a grasping assembly 50; the supporting base 31 is installed on the frame 20; the reset device 32 can reset the key hole 111 of the lock core cap 11 located on the supporting base 31 to a set direction; when the lock core cap 11 is located on the supporting base 31, the second side 113 of the lock core cap 11 faces the supporting base 31; the grasping assembly 50 includes a grasping member 51 and a fitting member 52, the grasping member 51 is used to place the lock core cap 11 located on the supporting base 31 onto the lock core body 12, and the fitting member 52 cooperates with the key hole 111 of the lock core cap 11 to position the lock core cap 11; among them, when the grasping member 51 grasps the lock core cap 11 located on the supporting base 31, the fitting member 52 presses against the positioning member 35 to disengage the positioning member 35 from the key hole 111 of the lock core cap 11; the fitting member 52 can position the key hole 111 to prevent the position of the lock core cap 11 from changing during the process of the grasping member 51 grasping the lock core cap 11.
