Description

Technical Field

[0001] This invention belongs to the field of lock assembly, specifically relating to a special lock inverted structure and lock assembly method. Background Technology

[0002] like Figures 1-3 As shown, the small lock includes a lock housing 91 and a lock cylinder 92. The lock housing 91 has a rotating channel 911. The lock cylinder 92 is inserted into the rotating channel 911 and can rotate relative to the lock housing 92. The lock housing 92 also has multiple mounting cavities 912 arranged along its length. One end of the mounting cavity 912 passes through and communicates with the rotating channel 911, while the other end is not through to close the mounting cavity 912. Therefore, it is not necessary to pass through the other end of the mounting cavity as in conventional locks. The main cover is used for sealing, as disclosed in Chinese Patent No. CN202311717854.7, or the sealing door is used for sealing, as disclosed in Chinese Patent No. CN201320062084.2, making the structure simpler and the number of parts fewer.

[0003] In addition, since the end of the mounting cavity 912 away from the rotation channel 911 is closed, it is necessary to provide an assembly channel 914 through the side of the rotation channel 911 away from the mounting cavity 912 so that when the lock cylinder 92 is not installed, the spring 93 and the flat-head pin 94 enter the mounting cavity 912 in sequence through the assembly channel 914 and the rotation channel 911.

[0004] The assembly of existing small locks requires manual assembly. Specifically, this is done by having the end of the assembly channel 914 facing upwards, away from the rotation channel 911. Figures 1-3 The lock, in the indicated state, is flipped upwards by 90°. Each set of springs 93 and flat-head pins 94 are then inserted downwards into the mounting cavity 912. With the lock cylinder 92 rotated a certain angle, the round-head pins 95 are inserted one by one into the alignment cavity 921 of the lock cylinder 92, gradually inserting the lock cylinder 92 into the rotating channel 911. When the lock cylinder 92 is inserted to each flat-head pin 94, a push pin needs to be manually inserted from the end of the rotating channel 911 away from the lock cylinder 92 into the rotating channel 911 and push against each flat-head pin 94 one by one, causing the flat-head pins to... The pin 94 is fully inserted into the mounting cavity 912, thus releasing the insertion restriction on the lock cylinder 92. In addition, due to the circumferential deflection of the lock cylinder 92, during the insertion of the lock cylinder 92, each alignment cavity 921 will not align with any mounting cavity 912, thus preventing the spring 93 from pressing the flat-head pin 94 into the alignment cavity 921. Finally, after the lock cylinder 92 is installed in place, by rotating the lock cylinder 92, each alignment cavity 921 is aligned with the corresponding mounting cavity 912, and under the action of the spring 93, the flat-head pin 94 is pushed into the alignment cavity 921 to complete the locking.

[0005] The problem with the above assembly method is that it requires manual assembly, resulting in low production efficiency. Furthermore, the small size of the lock makes manual operation difficult, further reducing production efficiency. Summary of the Invention

[0020] To enable those skilled in the art to better understand the present invention and to more clearly define the scope of protection of the present invention, the present invention will be described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present invention, and are merely a part of the embodiments of the present invention. The specific and direct descriptions of related structures are only for the convenience of understanding the present invention, and the specific features do not necessarily or directly limit the scope of the present invention. Conventional choices and substitutions made by those skilled in the art under the guidance of the present invention should be considered within the scope of protection of the present invention.

[0021] This invention discloses a special inverted lock structure for processing. Figures 1-3 The lock shown includes a lock housing 91 and a lock cylinder 92. The lock housing 91 has a through-hole rotation channel 911. The lock cylinder 92 is inserted into the rotation channel 911 and can rotate relative to the lock housing 91. The lock housing 91 also has five mounting cavities 912 arranged along the front-back direction. The lower end of each mounting cavity 912 communicates with the rotation channel 911, while the upper end is closed by the integral lock housing 91. Correspondingly, the upper end of the lock cylinder 92 has an alignment cavity 921. Each mounting cavity 912 contains a spring 93 and a flat-head pin 94, with the spring 93 on top and the flat-head pin 94 on the bottom. A round-headed tumbler 95 is installed in the alignment cavity 921, and a flat-headed tumbler 94 extends downward into the alignment cavity 921 under the action of a spring 93, and abuts against the round-headed tumbler 95. In addition, a lower protrusion 913 is provided below the rotation channel 911 and extends downward. The lower protrusion 913 is a long strip extending back and forth. The lower protrusion 913 is provided with an assembly channel 914 corresponding to each mounting cavity 912. Both ends of each assembly channel 914 are vertically penetrating, and the upper end extends upward into the rotation channel 911, so that the spring 93 and the flat-headed tumbler 94 can be installed upward through the assembly channel 914.

[0022] Specifically, such as Figures 4-6 As shown, it includes: Base 1; Clamping seat 2 is located on the front side of machine base 1, and a feeding position 21 is provided on the upper side of clamping seat 2; The feeding component 3 is a cylindrical rod extending forward and backward. Five cylindrical feeding through holes 31 are arranged along the forward and backward direction on the feeding component 3. The length direction of each feeding through hole 31 is perpendicular to the forward and backward direction, and both ends of the length of each feeding through hole 31 are arranged to penetrate the feeding component 3. The diameter of the feeding through hole 31 is d1. The rear end of the loading component 3 is connected to the first driving device 4, and the first driving device 4 works to drive the loading component 3 to slide in the front-back direction and rotate circumferentially with the axis of the loading component 3 as the rotation center line. Guide seat 5 is located below the loading part 3 and is fixedly installed on the machine base 1. Guide seat 5 is provided with a guide channel 51 extending in the front-back direction. The guide channel 51 is located on the rear side of the loading position 21 and is adjacent to it. The outer peripheral wall of the lower side of the loading part 3 is attached to the peripheral wall of the guide channel 51, so that the guide channel 51 has the ability to slide and guide the loading part 3 in the front-back direction and to close the lower end of the loading through hole 31. There are 5 top material components 61, which are arranged in the front-to-back direction and located below the loading position 21. Specifically, the top material component 61 is a thin cylindrical rod with a diameter of d2. The lower end of the top material member 61 is fixedly connected to the second drive device 62, and under the operation of the second drive device 62, the top material member 61 is driven to move upward and can extend into the upper material position 21. Where d1 > d2, so that when the top material 61 is inserted into the feeding through hole 31 with its top facing upward, there is a certain distance between the outer peripheral wall of the top material 61 and the inner peripheral wall of the feeding through hole 31, and this distance allows the feeding material 3 to rotate circumferentially.

[0023] The following lock assembly method can be performed using this special inverted lock structure, specifically including the following steps: S1. The lock housing 91 to be assembled is fixedly placed in the loading position 21, and the mounting cavity 912, the rotating channel 911, and the assembly channel 914 of the lock housing 91 are arranged downward in sequence. S2. With the feeding through hole 31 extending vertically, insert the spring 93 and flat-headed ball 94 to be assembled into the feeding through hole 31 from above. S3. The first driving device 4 works to drive the feeding component 3 to rotate counterclockwise so that the feeding through hole 31 is set at an angle. S4. The first driving device 4 operates to drive the feeding component 3 forward to enter the feeding position 21 so that the spring 93 and the flat-headed ball 94 enter the rotating channel 911. During the process of the feeding through hole 31 entering the rotating channel 911, the inclined feeding through holes 31 are respectively misaligned with the vertically extending mounting cavities 912 and the vertically extending assembly channels 914 to ensure that the spring 93 and the flat-headed ball 94 are located in the feeding through hole 31. S5. The first driving device 4 operates to drive the feeding component 3 to rotate clockwise so that the feeding through hole 31 is in a vertical state. In this state, the upper end of the feeding through hole 31 is aligned with the corresponding mounting cavity 912, and the lower end is aligned with the corresponding assembly channel 914. S6. The second drive device 62 operates to drive the top material component 61 upward into the feeding through hole 31 to push the spring 93 and the flat-headed ball 94 into the mounting cavity 912. S7. The first driving device 4 operates to drive the loading component 3 to rotate counterclockwise so that the loading through hole 31 and the corresponding mounting cavity 912 are misaligned. In step S3, the rotation angle of the loading component 3 is greater than that in step S7. In step S3, both ends of the loading through hole 31 are completely misaligned with the mounting cavity 912 and the assembly channel 914. In step S7, both ends of the loading through hole 31 are only partially misaligned with the mounting cavity 912 and the assembly channel 914 to ensure that the top component 61 is simultaneously located in the assembly channel 914 and the loading through hole 31. S8. The second drive device 62 operates to drive the top material member 61 to move downward and out of the loading through hole 31, and the spring 93 is reset in the mounting cavity 912 to press the flat-headed ball 94 downward against the outer peripheral wall of the loading member 3. S9. The first driving device 4 works to drive the feeding component 3 to rotate counterclockwise so that the feeding through hole 31 and the corresponding mounting cavity 912 are further misaligned. This position is set in accordance with the position of the feeding component 3 in S3. S10. With the alignment cavity 921 facing upward, the round-headed pins 95 to be assembled are respectively installed into the alignment cavity 921 of the lock cylinder 92, and the lock cylinder 92 is placed on the feeding part 3. At this time, the length orientation of the alignment cavity 921 and the length orientation of the feeding through hole 31 are parallel. S11. The first driving device 4 operates to drive the feeding component 3 to disengage from the rotating channel 911. Simultaneously, the lock cylinder 92 enters the rotating channel 911. During the process of the feeding through hole 31 disengaging from the rotating channel 911, each feeding through hole 31 is misaligned with each mounting cavity 912 and each assembly channel 914 to ensure that the spring 93 and the flat-head pin 94 are located in the mounting cavity 912. Simultaneously, during the process of the lock cylinder 92 entering the rotating channel 911, each alignment cavity 921 is misaligned with each mounting cavity 912 and each assembly channel 914 to ensure that the spring 93 and the flat-head pin 94 are located in the mounting cavity 912. S12. The first driving device 4 operates to drive the loading part 3 to rotate, thereby causing the lock core 92 to rotate until the alignment cavity 921 is vertical and the upper opening of the alignment cavity 921 faces upward to align with the mounting cavity 912. Then, under the reset of the spring 93, the flat-headed tumbler 94 is pushed downward into the alignment cavity 921 and abuts against the round-headed tumbler 95 to complete the assembly.

[0024] Therefore, by adopting the aforementioned inverted structure for specialized locks and performing the aforementioned lock assembly method, automated processing is achieved. Figures 1-3 Small locks with similar structures greatly improve production efficiency.

[0025] It should be noted that in step S1, the loading of the lock shell 91 can be done manually or automatically by other mechanical structures; in step S2, the loading of the spring 93 and the flat-head pin 94 can be done manually or automatically by other mechanical structures; in step S10, the loading of the round-head pin 95 can be done manually or automatically by other mechanical structures; and in step S11, the loading of the lock cylinder 92 can be done manually or automatically by other mechanical structures.

[0026] In order to more accurately position the lock case 91, the bottom of the loading position 21 is provided with a positioning groove 22 that matches the shape of the lower protrusion 913, so that the lower protrusion 913 fits into the positioning groove 22 to restrict the circumferential rotation of the lock case 91.

[0027] To achieve more precise positioning of the lock housing 91, five positioning sleeves 23 arranged in a front-to-back pattern and protruding upwards are provided in the positioning groove 22. The top material 61 moves upwards and extends upwards from the positioning sleeves 23. The positioning sleeves 23 and the assembly channel 914 are matched in shape and size, so that when the lock housing 91 is placed in the loading position 21, it is further positioned by the insertion of the positioning sleeves 23 and the assembly channel 914.

[0028] Specifically, in combination Figures 7-11 As shown, the first driving device 4 includes: The sliding base 41 is mounted on the machine base 1 by means of a combination of rail and slider; The sliding drive device 42 is a cylinder and is bolted to the base 1. The output shaft of the sliding drive device 42 faces forward and is fixedly connected to the sliding seat 41, so that the sliding seat 41 can be moved back and forth by pulling the sliding seat 41 through the output shaft of the sliding drive device 42. Rotary seat 43 is fitted to sliding seat 41 by means of a rotating sleeve, and the rotating seat 43 can rotate relative to the sliding seat 41 in the front-back direction as an axis. The rear end of the loading part 3 is inserted into the rotating seat 43, and the two are coaxially arranged. The rotation of the rotating seat 43 drives the loading part 3 to rotate. The first linkage gear 44 is located on the rear side of the rotating seat 43 and is fixedly connected to the rotating seat 43 by bolts, so that the two can rotate synchronously. The first linkage rack 45 is slidably disposed on the sliding seat 41 in the left and right direction, and the first linkage rack 45 is located below the first linkage gear 44. Through the meshing of the first linkage gear 44 and the first linkage rack 45, the sliding of the first linkage rack 45 can drive the first linkage gear 44 to rotate, thereby driving the rotation of the loading part 3 through the rotation of the rotating seat 43. The first cylinder 46 is fixed to the sliding seat 41 by bolts. The first cylinder 46 is located to the left of the first linkage rack 45, and the output shaft of the first cylinder 46 is threaded to the right and fixed to the first linkage rack 45. This allows the first cylinder 46 to push the first linkage rack 45 to the right, so that the first linkage rack 45 can be moved to the first state position. In the first state position, the feeding through hole 31 is in an inclined state, which satisfies the requirements of step S3. The second cylinder 47 is a large cylinder, while the first cylinder 46 is a small cylinder, so that the pushing force of the second cylinder 47 is greater than that of the first cylinder 46. The second cylinder 47 is fixed to the sliding seat 41 by bolts. The second cylinder 47 is located to the right of the first linkage rack 45, and the output shaft of the second cylinder 47 points to the left towards the first linkage rack 45. This allows the second cylinder 47 to push the first linkage rack 45 to the left, so that the first linkage rack 45 can be moved to the second state position. In the second state position, the feeding through hole 31 is in a vertical state, thus satisfying the requirements of steps S2 and S5.

[0029] In step S7, the second cylinder 47 needs to be stopped first, and then the first cylinder 46 needs to be started, so that the first cylinder 46 works and the feeding through hole 31 tilts and interferes with the top material part 61 for positioning.

[0030] Preferably, the sliding seat 41 is provided with a forward-protruding travel limit member 411 by means of insertion and fixing, and the outer peripheral wall of the rotating seat 43 is provided with an arc-shaped travel limit groove 431, in which the travel limit member 411 is located; wherein, in the first state position, the travel limit member 411 abuts against one end of the travel limit groove 431, and in the second state position, the travel limit member 411 abuts against the other end of the travel limit groove 431. Thus, the positioning is more precise through the cooperation of the travel limit member 411 and the travel limit groove 431.

[0031] In addition, combined Figure 12As shown, in this embodiment, the base 1 is provided with a guide clamp 71 and a third drive device 72 for driving the guide clamp 71. The guide clamp 71 is driven to move closer to the guide seat 5 to close the upper end of the feeding through hole 31. Specifically, the middle part of the guide clamp 71 is mounted on the base 1 by means of a hinge rod, and the axial direction of the hinge rod is along the front-back direction, and the hinge position is located on the right side of the guide seat 5. The third drive device 72 is a cylinder, and the end of the third drive device 72 away from the output shaft is hinged to the base 1. The right end of the output shaft and the guide clamp 71 are hinged; in addition, a clamping head 711 is provided on the left side of the guide clamp 71. The clamping head 711 is arc-shaped. Long strip-shaped alignment slots 712 extending forward and backward are provided at both ends of the arc of the clamping head 711. Long strip-shaped alignment slots 52 extending forward and backward are provided on the upper side of the guide seat 5 and on the left and right sides of the guide channel 51. The guide clamp 71 is flipped to approach the guide seat 5 so that each alignment slot 712 and the corresponding alignment slot 52 are engaged; in addition, the middle part of the clamping head 711 is connected to the guide clamp 71.

[0032] Therefore, step S2.1 is set between step S2 and step S3. Specifically, in step S2.1, the third drive device 72 operates to flip the guide clamp 71 so that the clamping head 711 faces the guide seat 5 and engages with the two sets of alignment slots 712 and alignment grooves 52. At this time, the clamping head 711 and the guide seat 5 work together to clamp the loading part 3, which can ensure that the spring 93 and the flat-head ball 94 are completely confined within the loading through hole 31. That is, it prevents the spring 93 from extending out of the loading through hole 31 due to its excessive length, which would prevent the spring 93 from entering and being unable to assemble during the insertion of the loading part 3 into the rotating channel 911.

[0033] In addition, combined Figure 13 , Figure 14As shown, the machine base 1 is equipped with two fixed grippers 81, a second linkage gear 82, a second linkage rack 83, and a fourth cylinder 84. The two fixed grippers 81 are symmetrically arranged on the left and right sides of the loading position 21, and the middle part of the fixed grippers 81 is flipped and mounted on the machine base 1 by means of a hinge rod, with the axis of the hinge rod along the front-back direction. Thus, by flipping the fixed grippers 81, the upper part of the fixed grippers 81 moves closer to the sides of the loading position 21 to clamp the lock shell 91, and moves away to release the clamping for loading and unloading the lock shell 91. The second linkage gear 82 is rotatably mounted on the machine base 1 by means of a shaft, with the axis of the shaft along the front-back direction. The second linkage gear 82 is equipped with a linkage part 821, which consists of two parts.
