Description

Technical Field

[0001] This invention belongs to the field of lock manufacturing and relates to a lock assembly machine. Background Technology

[0002] Padlocks are a common type of lock with a wide range of applications. The assembly sequence of a padlock body is as follows: bolt and cylinder. The bolt and cylinder are small in size, light in weight, and difficult to control. Currently, there are only single automatic cylinder assembly machines or bolt assembly machines on the market. Moreover, single assembly machines are not widely used. Most factories still use manual assembly combined with semi-automatic equipment, which results in low efficiency and high labor intensity. In addition, there are currently only single bolt assembly machines on the market. Summary of the Invention

[0046] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of the present invention may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0047] Example 1:

[0048] like Figures 3-26 As shown, a lock assembly machine includes a lock body assembly device 1, a bolt assembly device 2, a lock cylinder assembly device 3, and a shifting device 4. The shifting device 4 moves the lock body 9 sequentially between the lock body assembly device 1, the bolt assembly device 2, and the lock cylinder assembly device 3.

[0049] like Figures 1-2As shown, the lock body 9 has a lock cylinder hole 91, a vertical milling spring 92, a lock tongue hole 93, a shallow lock beam hole 94, and a deep lock beam hole 95. The lock body 9 is a conventional structure, and this application has not made any improvements to it.

[0050] like Figure 3 As shown, the latch 7 has a first protrusion 71 and a second protrusion 72, and a first groove 73 is formed between the first protrusion 71 and the second protrusion 72. The end of the latch 7 has a second groove 74. The latch 7 is a conventional structure and this application has not improved it.

[0051] like Figures 4-5 As shown, the lock assembly machine also includes a frame 8, and a lock body assembly device 1, a bolt assembly device 2, a lock cylinder assembly device 3, and a shifting device 4 are fixed on the frame 8. Specifically, the frame 8 has an operating cavity (not shown in the figure), and a base plate 81 is fixed at the bottom of the operating cavity. The lock body assembly device 1, the bolt assembly device 2, the lock cylinder assembly device 3, and the shifting device 4 are fixed on the base plate 81.

[0052] like Figures 6-7 As shown, the shifting device 4 has three stations, including a lock body loading station, a lock tongue loading station, and a lock cylinder loading station. The lock body assembly device 1 includes a lock body clamping mechanism 13, which is installed in the shifting device 4. The shifting device 4 drives the lock body clamping mechanism 13 to move synchronously between the stations. When the lock body assembly device 1 is in the lock body loading station, the lock body clamping mechanism 13 docks with the lock body 9 to be assembled and loads it. When the lock tongue assembly device 2 is in the lock tongue loading station, it docks with the lock body 9 on the shifting device 4 and loads it. When the lock cylinder assembly device 3 is in the lock cylinder loading station, it docks with the lock body 9 on the shifting device 4 and loads it.

[0053] like Figures 6-7 As shown, the lock body assembly device 1 also includes a lock body feeding mechanism 11, a lock body straightening mechanism 12, and a lock body discharging mechanism 14. The feeding end of the lock body feeding mechanism 11 is connected to the lock body tray (not shown in the figure) through the lock body hopper 10. The lock body tray can be a conventional vibratory feeder. The discharging end of the lock body feeding mechanism 11 is connected to the lock body straightening mechanism 12 and the lock body clamping mechanism 13. The lock body tray transports the lock body 9 to be assembled to the lock body feeding mechanism 11 through the lock body hopper 10. The lock body feeding mechanism 11 moves the lock body 9 to the docking position of the lock body straightening mechanism 12. The lock body straightening mechanism 12 straightens the position of the lock body 9. The lock body clamping mechanism 13 clamps the straightened lock body 9. The shifting device 4 moves the lock body clamping mechanism 13 and the lock body 9 to the lock tongue feeding station.

[0054] like Figures 6-7As shown, the lock body feeding mechanism 11 includes a push lock body drive 111, a lock body drive 112, and a lock body clamp 113. The push lock body drive 111 pushes the lock body 9 to the lock body clamp 113, and the lock body drive 112 pushes the lock body 9 to move upward to dock with the lock body straightening mechanism 12.

[0055] like Figures 6-7 As shown, the locking body clamp 113 is located on the pushing path of the locking body drive 111, and the locking body drive 112 is fixed on the base plate 81 and located below the locking body clamp 113.

[0056] like Figures 6-7 As shown, the push lock body drive 111 includes a push lock body cylinder. The push lock body cylinder pushes the lock body 9 to move upward to the lock body clamp 113. The push lock body cylinder can also fix a push lock body component 114. When the push lock body cylinder 111 is started, it drives the push lock body component 114 to move, and the push lock body component 114 pushes the lock body 9.

[0057] like Figures 6-7 As shown, the locking body drive 112 includes a locking body cylinder. A push plate is fixed at the output end of the locking body cylinder. The push plate is located at the bottom of the locking body clamp 113. The locking body drive 111 pushes the lock body 9 into the locking body clamp 113. The bottom of the lock body 9 is supported by the push plate. The locking body drive 112 pushes the push plate and thus moves the lock body 9 upward to dock with the lock body correction mechanism 12.

[0058] like Figures 6-7 As shown, the lock body feeding mechanism 11 also includes an upper lock body frame, which includes an upper lock body base plate 115 and upper lock body side plates 116 symmetrically fixed on both sides of the upper lock body base plate 115. The lock body push cylinder, the upper lock body cylinder, and the upper lock body clamp 113 are fixed on the upper lock body base plate 115. The upper lock body base plate 115 is fixed on the base plate 81 of the frame 8. The two sets of upper lock body side plates 116 form a lock body moving channel. The lock body push cylinder 111 pushes the lock body 9 to move along the lock body moving channel, thereby restricting and guiding the movement of the lock body 9.

[0059] like Figures 6-7 As shown, the upper part of the two sets of upper lock body side plates 116 is connected to the lock body hopper 10, and the lock body 9 in the lock body hopper 10 falls into the lock body moving channel; preferably, the upper side of the upper lock body side plate 116 is inclined outward to facilitate the lock body 9 falling into the lock body moving channel.

[0060] like Figure 6As shown, the lock body straightening mechanism 12 includes a lock body straightening cylinder 121 and a lock body straightening punch 122. The lock body straightening punch 122 is fixed at the output end of the lock body straightening cylinder 121. Under the drive of the lock body straightening cylinder 121, the lock body straightening punch 122 is inserted into the bolt hole 93 of the lock body 9. At this time, the bolt hole 93 serves as a positioning hole to straighten the position of the lock body. When the bolt hole 93 of the lock body 9 faces the lock body straightening mechanism 12, the bolt hole 93 is directly opposite the lock body straightening punch 122. At this time, the lock body straightening punch 122 can be inserted into the bolt hole 93, and the lock body 9 in this position is the required lock body. When the bolt hole 93 of the lock body 9 is away from the lock body straightening mechanism 12, the lock body straightening punch 122 cannot be inserted into the bolt hole 93. At this time, the lock body 9 is in the wrong position. The lock body straightening mechanism 12 can also be equipped with an alarm structure. When the lock body 9 is in the wrong position, the alarm structure will alert the operator to handle the situation.

[0061] like Figure 6 As shown, the lock body clamping mechanism 13 includes a lock body clamping cylinder 131, a lock body clamping fixing member 132, and a lock body clamp 133. The lock body clamping cylinder 131 and the lock body clamping fixing member 132 are fixedly connected to the shifting device 4. The lock body clamp 133 is engaged with the lock body clamping fixing member 132. The output shaft of the lock body clamping cylinder 131 passes through the lock body clamping fixing member 132 and extends into the interior of the lock body clamp 133.

[0062] like Figure 6 As shown, a through hole (not shown in the figure) is fixed on one side of the lock body clamp 133, and pressure plates 1331 are fixed on both sides of the through hole. Figure 6 From a visual angle, the pressure plate 1331 and the output shaft of the lock body clamping cylinder 131 are located on the front and rear sides of the lock body 9, and the pressure plate 1331 and the output shaft clamp the lock body 9 on the front and rear sides.

[0063] The loading and clamping process of lock body 9 is as follows:

[0064] The shifting device 4 drives the lock body clamping mechanism 13 to move above the upper lock body clamping 113, i.e. the lock body loading station. At this time, the upper lock body clamping 113 and the lock body clamping 133 are in opposite positions. The upper lock body cylinder 112 is activated to move the corrected lock body 9 from the upper lock body clamping 113 to the inside of the lock body clamping 133. The end of the output shaft of the lock body clamping cylinder 131 is activated to abut and press against the lock body 9, thereby realizing the loading and clamping of the lock body 9.

[0065] like Figures 6-7As shown, the lock body discharge mechanism 14 is fixed on the frame 8. The lock body discharge mechanism 14 includes a lock body push-out cylinder 141, a lock body push-out plate 142, a lower lock body cylinder (not shown in the figure), a lock body discharge cylinder 143, and a lock body displacement component 144. The lock body push-out cylinder 141, the lock body push-out plate 142, the lower lock body cylinder, and the lock body discharge cylinder 143 are fixed on the base plate 81. The output shaft of the lock body push-out cylinder 141 passes through and faces the lock body cylinder 143. The lock body displacement component 144 is fixed on the output shaft of the lock body discharge cylinder 143.

[0066] The lock body discharge mechanism 14 also includes a first discharge guide plate 145 and a second guide plate 146. The first discharge guide plate 145 is fixed on the base plate 81 and located between the base plate 81 and the lock body displacement member 144, and is used to guide the lock body 9 during the process of being driven by the lock body push-out cylinder 141. The second guide plate 146 is fixed on the base plate 81 and located between the lock body displacement member 144 and the discharge port, and is used to guide the lock body 9 during the process of being driven by the lock body push-out cylinder 143.

[0067] The assembly process for unloading the lock body is as follows:

[0068] After the lock cylinder and vertical milling spring are assembled at the lock cylinder loading station, the assembled lock body needs to be unloaded. At this time, the lock cylinder loading station is the lock body unloading station. The lock body ejection plate 142 is located below the lock body clamp 133. The lower lock body cylinder is started, and the push plate at the end of its output shaft moves up. The lock body clamp 133 is released, and the lock body 9 falls into the push plate. The lower lock body cylinder is reset, and the lock body 9 is moved into the lock body ejection plate 142. The lock body ejection cylinder 141 is started to push the lock body 9 to the position of the lock body displacement component 144. The lock body ejection cylinder 143 is started to drive the lock body displacement component 144 to move the lock body 9 to the unloading position.

[0069] like Figure 7 As shown, the shifting device 4 includes a shifting frame 40, on which a rotating power mechanism is fixed. The lock body clamping mechanism 13 is fixed on the rotating power mechanism. The rotating power mechanism drives the lock body clamping mechanism 13 to move between the lock body loading station, the lock tongue loading station, and the lock cylinder loading station.

[0070] The rotational power mechanism can employ servo motor and ball screw drive, servo motor and synchronous belt drive, cylinder drive, etc., to achieve linear reciprocating motion. In this embodiment, it is set to cylinder drive. Specifically, the rotational power mechanism includes a shifting slide rail 41, a shifting slider 42 slidably connected to the shifting slide rail 41, a shifting plate 43, a connecting piece 44, a first shifting cylinder 45, and a second shifting cylinder 46. The shifting slide rail 41, the first shifting cylinder 45, and the second shifting cylinder 46 are fixedly mounted. In the shifting frame 40, the shifting plate 43 is fixed on the shifting slider 42. The lock body clamping cylinder 131, the lock body clamping fixture 132, and the connecting piece 44 are fixed on the shifting plate 43. The output shaft of the first shifting cylinder 45 is engaged with the connecting piece 44. The second shifting cylinder 46 acts on the connecting piece 44. The first shifting cylinder 45 and the second shifting cylinder 46 drive the connecting piece 44 to make the shifting device 4 move between the lock body loading station, the lock tongue loading station, and the lock cylinder loading station.

[0071] like Figure 8 As shown, the latch assembly device 2 includes a spring feeding mechanism 20, a first latch feeding mechanism 21, a second latch feeding mechanism 22, a spring latch assembly mechanism 23, a latch feeding mechanism 24, a latch pushing mechanism 25, and a latch limiting mechanism 26. The spring latch assembly mechanism 23 is connected to the spring feeding mechanism 20, the first latch feeding mechanism 21, the second latch feeding mechanism 22, and the latch feeding mechanism 24. The latch feeding mechanism 24 is connected to the latch pushing mechanism 25. The latch limiting mechanism 26 is connected to the lock body to be assembled with the latch.

[0072] Spring feeding mechanism 20, first locking tongue feeding mechanism 21, second locking tongue feeding mechanism 22, and spring locking tongue assembly mechanism 23 are mounted on locking tongue mounting plate 271, and locking tongue mounting plate 271 is fixedly mounted on base plate 81 of frame 8.

[0073] like Figure 8 As shown, the spring feeding mechanism 20 includes a spring feeding drive 201, a spring feeding fixture 202, a spring pushing drive 203, and a spring pushing pin 204. The spring feeding fixture 202 is connected to the spring feeding drive 201, the spring pushing drive 203 is connected to the spring pushing pin 204, and the spring feeding fixture 202 is connected to the spring tray, which is a conventional vibratory feeder. The spring feeding fixture 202 receives the springs fed by the spring tray. The spring feeding drive 201 controls the spring feeding fixture 202 to move to the spring feeding station. The spring feeding station is located in front of the spring pushing pin 204. The spring pushing drive 203 controls the spring pushing pin 204 to move and transport the springs in the spring feeding fixture 202 to the spring locking tongue assembly mechanism 23.

[0074] like Figure 8As shown, the spring feeding drive 201 includes a spring feeding cylinder 2011, a spring feeding slide rail 2012, and a spring feeding slider 2013. The spring feeding cylinder 2011 and the spring feeding slide rail 2012 are fixedly mounted on the lock tongue mounting plate 271. The spring feeding slider 2013 is slidably connected to the spring feeding slide rail 2012. The spring feeding fixture 202 is fixedly mounted on the spring feeding slider 2013 through a spring feeding fixture connector. The spring feeding cylinder 2011 is connected to the spring feeding fixture 202. When the spring feeding cylinder 2011 is activated, it drives the spring feeding fixture 202 to slide along the spring feeding slide rail 2012.

[0075] like Figure 8 As shown, the spring feeding fixture 202 is provided with a spring hole 2021, which is connected to the discharge port of the spring tray. The springs in the spring tray are transported from the discharge port to the spring hole 2021.

[0076] like Figure 8 As shown, the spring feeding mechanism 20 also includes a spring sensing structure. The spring sensing structure is installed inside or opposite the spring hole 2021. The spring sensing structure is used to sense whether a spring is present in the spring hole 2021. If a spring is present, the spring sensing structure sends a signal to the spring feeding drive 201, which then initiates the feeding operation. If no spring is present in the spring hole 2021, the spring sensing structure issues an alarm or sends a warning to the control panel or other equipment. The spring sensing structure can be a conventional photoelectric sensor, pressure sensor, etc. The sensing principle, structure, and installation can be determined according to actual needs. In this embodiment, the spring sensing structure is a photoelectric sensor. The latch mounting plate 271 is fixed with a sensing element fixing member 272, which has a sensing element fixing hole opposite to the spring hole 2021. The spring sensing structure is fixed to the sensing element fixing member 272 and faces the spring hole 2021 through the sensing element fixing hole, thereby achieving the purpose of sensing whether a spring is present in the spring hole 2021.

[0077] like Figure 8 As shown, the spring pusher drive 203 includes a spring pusher cylinder 2031, which is fixed to the locking tongue mounting plate 271 via a pusher base plate. The spring pusher 204 is fixed to the output shaft of the spring pusher cylinder 2031 and is driven to reciprocate by the spring pusher cylinder 2031.

[0078] like Figure 8 As shown, the spring pusher drive 203 also includes a spring pusher guide block 205, which is fixedly mounted on the latch mounting plate 271. The spring pusher guide block 205 is fixedly provided with a spring pusher guide tube 2051, and the spring pusher pin 204 slides through the spring pusher guide tube 2051. The spring pusher guide block 205 supports the spring pusher pin 204 and guides its movement.

[0079] like Figure 8 As shown, the spring feeding mechanism 20 may also include a limiting structure 206, which is used to limit the stroke and positioning of the spring feeding cylinder 2011. In other embodiments, the travel stroke of the spring feeding cylinder 2011 may also be set, but this application does not limit it.

[0080] like Figure 8 As shown, the first latch feeding mechanism 21 and the second latch feeding mechanism 22 are distributed on both sides of the spring latch assembly mechanism 23 and are fixedly connected to the latch mounting plate 271. The first latch feeding mechanism 21 is used to feed the first latch, and the second latch feeding mechanism 22 is used to feed the second latch. The first latch feeding mechanism 21 and the second latch feeding mechanism 22 realize the feeding of the double latches of the first latch and the second latch. The first latch feeding mechanism 21 and the second latch feeding mechanism 22 have the same structure. In this embodiment, the first latch feeding mechanism 21 is used as an example for explanation.

[0081] like Figure 8 As shown, the first latch feeding mechanism 21 includes a latch feeding drive 211, a latch pin 212, and a latch feeding fixture 213. The latch feeding drive 211 is fixedly connected to the latch pin 212, and the latch feeding fixture 213 is connected to the latch material tray. The latch material tray is a conventional vibratory feeder. The latch feeding fixture 213 receives the latches fed by the latch material tray. The latch feeding drive 211 controls the latch pin 212 to move and feed the latches in the latch feeding fixture 213 to the spring latch assembly mechanism 23.

[0082] Preferably, the locking tongue feeding drive 211 uses power equipment such as cylinders and motors.

[0083] The latch feeding drive 211 is fixedly connected to the latch mounting plate 271 via the latch feeding fixture, and the latch feeding jig 213 is fixedly connected to the latch mounting plate 271 via the latch feeding base.

[0084] like Figure 9 As shown, the latch loading fixture 213 includes a first latch fixture 2131, a second latch fixture 2132, and a latch guide 2133. The second latch fixture 2132 and the latch guide 2133 are respectively fixed to the first latch fixture 2131. The three fixtures form a moving channel 2135 for the latch 7 to move. The latch guide 2133 is provided with a guide groove 2134, which is connected to the moving channel 2135. The latch 7 enters the moving channel 2135 from the guide groove 2134. The shape of the guide groove 2134 matches the latch 7, thereby restricting the direction of the latch 7 when it enters the moving channel 2135.

[0085] like Figure 10As shown, the upper locking pin 212 has a latch 2121 at its end, which engages with the second groove 74 to form a fit, preventing the locking tongue 7 from rotating during the process of the upper locking pin 212 pushing the locking tongue 7 to move, thus facilitating the subsequent assembly of the locking tongue.

[0086] Specifically, the guide groove 2134 restricts the guiding of the latch 7: the cross-sectional shape of the guide groove 2134 matches the cross-section of the latch 7, that is, the guide groove 2134 has a slot to accommodate the first protrusion 71 and the second protrusion 72. The guide groove 2134 has a guide post. The latch guide 2133 is connected to the outlet of the latch material tray. When the latch enters the guide groove of the latch guide 2133 from the outlet, the guide post is inserted into the first slot 73, and the first protrusion 71 and the second protrusion 72 are inserted into the slot. At this time, the direction of the latch 7 entering the guide groove and the moving channel 2135 is limited.

[0087] The first latch feeding mechanism 21 also includes a latch feeding sensing structure. The latch feeding sensing structure is fixed to the latch feeding fixture 213 to sense whether there is a latch in the moving channel 2135. If there is a latch in the moving channel 2135, the latch feeding sensing structure sends a signal to the latch feeding drive 211, and the latch feeding drive 211 starts to perform the feeding operation. If there is no latch in the moving channel 2135, the latch feeding sensing structure issues an alarm or sends a warning to the control panel or other equipment. The latch feeding sensing structure can use conventional photoelectric sensors, pressure sensors, etc. The sensing principle, structure, and installation can be determined according to actual needs.

[0088] The first latch feeding mechanism 21 latch feeding process is as follows:

[0089] When the latch 7 is introduced into the moving channel 2135 from the latch guide 2133 in a defined direction, the latch pin 2121 engages with the second groove 74 of the latch, and the latch feeding drive 211 is activated to push the latch 7 to the spring latch assembly mechanism 23 using the latch pin.

[0090] like Figure 11 As shown, the spring latch assembly mechanism 23 includes a latch assembly drive 231 and a latch assembly component 232. The latch assembly drive 231 is connected to the latch assembly component 232. The latch assembly component 232 is driven by the latch assembly drive 231 to dock with the spring feeding mechanism 20, the first latch feeding mechanism 21, and the second latch feeding mechanism 22, thereby realizing the feeding and assembly of the spring of the spring feeding mechanism 20, the first latch of the first latch feeding mechanism 21, and the second latch of the second latch feeding mechanism 22.

[0091] like Figure 11As shown, the latch assembly drive 231 includes a latch assembly shift cylinder 2311, a latch assembly shift slide rail 2312, and a latch assembly shift slider 2313. The latch assembly shift cylinder 2311 and the latch assembly shift slide rail 2312 are fixed on the latch mounting plate 271. The latch assembly shift slider 2313 is slidably connected to the latch assembly shift slide rail 2312. The latch assembly component 232 is fixed on the latch assembly shift slider 2313 through the latch assembly advance and retreat base plate 2314. The latch assembly shift cylinder 2311 is connected to the latch assembly advance and retreat base plate 2314. When the latch assembly shift cylinder 2311 is activated, it drives the latch assembly component 232 to slide along the latch assembly shift slide rail 2312.

[0092] like Figure 11 As shown, the latch assembly drive 231 controls the latch assembly component 232 to move in three stations, specifically including a spring feeding station, a first latch feeding station, and a second latch feeding station. The latch assembly drive 231 controls the latch assembly component 232 to move to the spring feeding station, where the latch assembly component 232 docks with the spring feeding mechanism 20. The latch assembly drive 231 then controls the latch assembly component 232 to move to the first latch feeding station, where the latch assembly component 232 docks with the first latch feeding mechanism 21. The latch assembly drive 231 then controls the latch assembly component 232 to move to the second latch feeding station, where the latch assembly component 232 docks with the second latch feeding mechanism 22. The second latch feeding station also serves as the latch spring feeding station. After the first latch, spring, and second latch are assembled by the latch assembly component 232, they are simultaneously pushed to the latch feeding mechanism 24 by the second latch feeding mechanism 22.

[0093] like Figure 11 As shown, the latch assembly component 232 includes a latch assembly fixture 2321, a first push-lock structure, and a second push-lock structure. The latch assembly fixture 2321 has a receiving cavity 2322, which is configured as a feeding channel for the spring, the first latch, and the second latch. The first push-lock structure and the second push-lock structure are movably disposed in the latch assembly fixture 2321, and the first push-lock structure and the second push-lock structure respectively restrict the movement of the first latch and the second latch in the feeding channel.

[0094] The latch assembly fixture 2321 is fixedly mounted on the latch assembly advance and retreat base plate 2314. The first push-lock structure and the second push-lock structure are located on both sides of the latch assembly fixture 2321 and are fixedly connected to the latch assembly advance and retreat base plate 2314.

[0095] like Figure 11As shown, the first push-lock structure includes a first push-lock cylinder 2323 and a first push-lock plate 2324. The first push-lock cylinder 2323 is opposite to the first push-lock plate 2324. The first push-lock cylinder 2323 is fixed on the latch assembly advance and retraction base plate 2314. The first push-lock plate 2324 is driven by the first push-lock cylinder 2323 to move towards the latch assembly fixture 2321. The first push-lock plate 2324 is provided with a first protrusion. After the first push-lock plate 2324 is pressed by the first push-lock cylinder 2323, the first protrusion is inserted into the receiving cavity 2322 to limit the first latch.

[0096] The latch assembly fixture 2321 is provided with a first push-lock groove, and a first push-lock plate 2324 is inserted into the first push-lock groove and can move in the first push-lock groove. The first push-lock plate 2324 and the latch assembly fixture 2321 are connected by a spring.

[0097] The second push-lock structure includes a second push-lock cylinder 2325 and a second push-lock plate 2326. The second push-lock cylinder 2325 is opposite to the second push-lock plate 2326. The second push-lock cylinder 2325 is fixed on the latch assembly advance and retraction base plate 2314. The second push-lock plate 2326 is driven by the second push-lock cylinder 2325 to move towards the latch assembly fixture 2321. The second push-lock plate 2326 is provided with a second protrusion. After the second push-lock plate 2326 is pressed by the second push-lock cylinder 2325, the second protrusion is inserted into the receiving cavity 2322 to limit the second latch.

[0098] The latch assembly fixture 2321 is provided with a second push-lock slot, and the second push-lock plate 2326 is inserted into the second push-lock slot and can move in the second push-lock slot. The second push-lock plate 2326 and the latch assembly fixture 2321 are connected by a spring.

[0099] like Figures 12-15 As shown, the spring latch assembly mechanism 23 may also include a latch limiting structure 234. The latch limiting structure 234 is disposed on the latch assembly fixture 2321 and located above the receiving cavity 2322. It is used to limit the movement of the latch in the height direction, so as to prevent the latch from deviating in the height direction during the feeding and pushing process, and effectively improve the efficiency of latch feeding and pushing.

[0100] The latch limiting structure 234 includes a latch fixture 2341 and a latch assembly clamping member 2342. The latch assembly clamping member 2342 is connected to the latch assembly fixture 2321. The latch assembly clamping member 2342 is disposed in the latch fixture 2341 and connected by a spring. The latch assembly clamping member 2342 is opposite to the receiving cavity 2322 and is in contact with the latch. The latch assembly clamping member 2342 is distributed along the latch feeding and pushing path. The latch assembly clamping member 2342 presses the latch from above.

[0101] The locking tongue fixture 2341 and the locking tongue assembly clamping part 2342 are connected, specifically:

[0102] The latch fixture 2341 has a mounting hole 23411. The latch assembly clamping member 2342 is adapted to be installed in the mounting hole 23411. The mounting hole 23411 has a T-shaped structure, and the latch assembly clamping member 2342 has a matching T-shaped structure. During installation, the latch assembly clamping member 2342 slides in the mounting hole 23411, thereby restricting the height of the latch assembly clamping member 2342. The latch fixture 2341 has a pin hole 23412, and the latch assembly clamping member 2342 has a pin through hole 23421. The pin hole 23412 and the pin through hole 23421 are opposite to each other and are connected by a pin, thereby restricting the front and rear directions of the latch assembly clamping member 2342 and achieving stable installation of the latch assembly clamping member 2342 in the latch fixture 2341.

[0103] The latch fixture 2341 has two sets of spring mounting holes 23413, which communicate with the mounting holes 23411. Springs are installed in the spring mounting holes 23413, connecting the latch assembly clamping member 2342 to the latch fixture 2341. The latch assembly clamping member 2342 uses the spring force to contact the latch, preventing it from moving in the height direction. When the latch is subjected to force for feeding or pushing, because the spring force is small and the direction of the external force is different from the spring force, it can overcome the spring force and push the latch back and forth.

[0104] like Figure 11 As shown, the spring latch assembly mechanism 23 may also include a latch limiting structure 233, which is used to limit the stroke and positioning of the latch assembly shift cylinder 2311. In other embodiments, the movement stroke of the latch assembly shift cylinder 2311 may also be set, but this application does not limit it.

[0105] The assembly process of the latch and spring is as follows:

[0106] The first push-lock cylinder 2323 is activated, pushing the first push-lock plate 2324 towards the latch assembly fixture 2321. The first protrusion is inserted into the receiving cavity. After the first latch feeding mechanism 21 feeds the first latch, the latch assembly shift cylinder 2311 drives the latch assembly fixture 2321 to move to the first latch feeding station. The latch feeding drive 211 is activated, pushing the first latch into the receiving cavity 2322 in the direction of arrow b. The first latch feeding mechanism 21 is reset. After the spring feeding mechanism 20 feeds the spring, the latch assembly shift cylinder 2311 drives the latch assembly fixture 2321 to move to the spring feeding station. The spring push cylinder 2031 drives the spring push pin 204 in the direction of arrow a to push the spring into the receiving cavity 2322. The second push-lock cylinder 23235 pushes the second push-lock plate 23. 26 moves towards the latch assembly fixture 2321, the second protrusion is inserted into the receiving cavity, and after the second latch is fed onto the second latch feeding mechanism 22, the latch assembly displacement cylinder 2311 drives the latch assembly fixture 2321 to move to the second latch feeding station. The latch feeding drive of the second latch feeding mechanism 22 starts and pushes the second latch to the receiving cavity 2322 in the direction of arrow a. At this time, the first push buckle cylinder 2323 and the second push buckle cylinder 2325 are reset, the first push buckle plate 2324 and the second push buckle plate 2326 are reset under the action of spring restoring force, the first protrusion and the second protrusion move away from the receiving cavity 2322, the latch feeding drive of the second latch feeding mechanism 22 continues to run, and the latch pin continues to move to push the second latch, the spring and the first latch to the latch feeding mechanism 24.

[0107] like Figures 15-18 As shown, the latch feeding mechanism 24 includes a latch feeding drive 241 and a latch carrying mechanism 242. The latch feeding drive 241 is connected to the latch carrying mechanism 242. The latch feeding drive 241 controls the latch carrying mechanism 242 to move to dock with the latch assembly fixture 2321 or with the latch pushing mechanism 25.

[0108] The latch feeding drive 241 can be driven by a servo motor and ball screw, a servo motor and synchronous belt, or a cylinder to achieve linear reciprocating motion. In this embodiment, it is set to be driven by a servo motor and ball screw. The latch feeding drive 241 includes a lock body feeding frame 2410, a ball screw assembly 2411, a feeding connecting plate 2413, a lock body feeding slide rail 2414, and a lock body feeding slider 2415. The lock body feeding frame 2410 is fixed on the latch mounting plate 271, and the ball screw assembly 2411 is set... In the lock body feeding frame 2410, the lock body feeding slide rail 2414 is fixedly mounted on the lock body feeding frame 2410, and the lock body feeding slider 2415 is slidably mounted on the lock body feeding slide rail 2414. The lock body feeding slider 2415 is connected to the moving block of the ball screw assembly 2411 through the feeding connecting plate 2413. Under the sliding connection between the ball screw assembly 2411 and the lock body feeding slider 2415 and the lock body feeding slide rail 2414, the lock body feeding slider 2415 moves linearly along the lock body feeding slide rail 2414.

[0109] The latch bearing mechanism 242 includes a material changing fixing part 2421 and a latch changing assembly. The latch changing assembly is fixed to the material changing fixing part 2421. The material changing fixing part 2421 is connected to the lock body feeding slider 2415, thereby realizing the movement of the latch bearing mechanism 242 under the driving action of the ball screw assembly 2411.

[0110] The connection between the locking tongue changing assembly and the changing fixing part 2421 is as follows:

[0111] The material changing fixing component 2421 is provided with a material changing fixing cavity 24211 and a material changing fixing hole 24212. The material changing fixing hole 24212 communicates with the material changing fixing cavity 24211. The locking tongue material changing component is set in the material changing fixing cavity 24211. The material changing fixing hole 24212 is provided with fasteners such as tightening screws. The tightening screws are used to press the locking tongue material changing component into the material changing fixing cavity 24211.

[0112] The latch replacement assembly includes a first latch replacement component 2422, a second latch replacement component 2423, and a third latch replacement component 2424. The first latch replacement component 2422 is connected to the third latch replacement component 2424, and the second latch replacement component 2423 is locked inside the third latch replacement component 2424.

[0113] The third latch replacement component 2424 is provided with a latch communication channel 24241 and a latch mounting hole 24242. The latch communication channel 24241 is connected to the receiving cavity 2322 and receives the latch and spring from the receiving cavity 2322.

[0114] The second latch replacement component 2423 is adapted to be installed in the latch mounting hole 24242. The latch mounting hole 24242 has a T-shaped structure, and the second latch replacement component 2423 has a matching T-shaped structure. During installation, the second latch replacement component 2423 slides within the latch mounting hole 24242, thereby restricting the height of the second latch replacement component 2423. The third latch replacement component 2424 is provided with a latch positioning through hole 24243. 423 is provided with a latch positioning hole 24231, and the first latch replacement component 2422 is provided with a latch positioning protrusion 24221. The latch positioning protrusion 24221 is opposite to the latch positioning hole 24231 and the latch positioning through hole 24243 respectively, and is engaged, thereby restricting the second latch replacement component 2423 in the front and rear directions, so as to realize the stable installation of the second latch replacement component 2423 on the first latch replacement component 2422 and the third latch replacement component 2424.

[0115] The third latch changing component 2424 has two sets of latch spring mounting holes 24244, which are connected to the latch mounting holes 24242. Each latch spring mounting hole 24244 contains a spring that connects the second latch changing component 2423 to the first latch changing component 2422. The second latch changing component 2423 contacts the latch based on the spring force, preventing it from moving in the height direction. When the latch is subjected to force for feeding or pushing, the spring force is small and the direction of the external force is different from the spring force, thus overcoming the spring force to push the latch back and forth.

[0116] like Figure 8 As shown, the latch pusher mechanism 25 includes a latch pusher drive 251 and a latch pusher pin 252. The latch pusher drive 251 is connected to the latch pusher pin 252. Driven by the latch pusher drive 251, the latch pusher pin 252 moves forward and pushes the first latch, spring and second latch in the latch bearing mechanism 242 into the latch hole 93 of the lock body.

[0117] The latch pusher 251 includes a latch pusher cylinder, which is fixed on the base plate 81 via a latch pusher frame 250. The output shaft of the latch pusher cylinder is connected to the latch pusher pin 252.

[0118] The locking tongue pushing mechanism 25 also includes a locking tongue pushing guide 254, which is fixed on the locking tongue pushing frame 250. The locking tongue pushing pin 252 slides through the locking tongue pushing guide 254.

[0119] like Figure 8 As shown, the latch limiting mechanism 26 includes a latch limiting drive 261 and a limiting pin 262. The latch limiting drive 261 is connected to the limiting pin 262. Under the drive of the latch limiting drive 261, the limiting pin 262 is pushed upward and inserted into the shallow hole 94 of the lock beam of the lock body.

[0120] The locking tongue limit drive 261 includes a locking tongue pusher cylinder, which is fixed to the base plate 81 via a locking tongue limit frame 260. The output shaft of the locking tongue pusher cylinder is connected to the limit pin 262.

[0121] The locking tongue limiting mechanism 26 also includes a locking tongue limiting guide 264, which is fixed on the locking tongue limiting frame 260, and the limiting pin 262 slides through the locking tongue limiting guide 264.

[0122] like Figure 4 , Figure 5 , Figure 19 As shown, the lock cylinder assembly device 3 includes a lock cylinder feeding mechanism 31, a lock cylinder pushing mechanism 32, a vertical milling spring sorting mechanism 33, and a vertical milling spring loading mechanism 34. The lock cylinder feeding mechanism 31 includes a lock cylinder feeding frame 310, a lock cylinder feeding drive 311, a lock cylinder clamp 312, a lock cylinder pressing component 313, and a lock cylinder sensing device 314. The lock cylinder feeding drive 311 is installed on the lock cylinder feeding frame 310. The lock cylinder feeding drive 311, the lock cylinder pressing component 313 and the lock cylinder clamp 312 are connected. The lock cylinder sensing device 314 is set in the lock cylinder clamp 312. The lock cylinder clamp 312 clamps the lock cylinder. The lock cylinder feeding drive 311 drives the lock cylinder clamp 312 to move linearly back and forth. The lock cylinder pressing component 313 is used for clamping and releasing the lock cylinder inside the lock cylinder clamp 312.

[0123] The lock cylinder delivery drive 311 can be driven by a servo motor and ball screw, a servo motor and synchronous belt, or a cylinder to achieve linear reciprocating motion. In this embodiment, it is set to cylinder drive. Specifically, the lock cylinder delivery drive 311 includes a lock cylinder delivery cylinder 3111 and a second linear slide rail slider motion structure. The lock cylinder delivery cylinder 3111 is fixedly connected to the lock cylinder delivery frame 310 through the lock cylinder delivery base plate. The slide rail of the second linear slide rail slider motion structure is fixedly connected to the lock cylinder delivery base plate. The slider is fixedly connected to the output end of the lock cylinder delivery cylinder 3111. The slider is connected to the lock cylinder clamp 312. The lock cylinder delivery cylinder 3111 starts to drive the lock cylinder clamp 312 to move back and forth.

[0124] The lock cylinder clamp 312 is fixedly provided with a lock cylinder cavity 3121, and a positioning strip 3122 is provided inside the lock cylinder cavity 3121. The positioning strip 3122 is used to position the lock cylinder.

[0125] like Figures 20-22As shown, the lock cylinder pressing member 313 includes a first lock cylinder clamp 3131, a second lock cylinder clamp 3132, a third lock cylinder clamp 3133, a fourth lock cylinder clamp 3134, and a pressing member 3135. The first lock cylinder clamp 3131 and the fourth lock cylinder clamp 3134 have the same structure and are symmetrically fixed on both sides of the lock cylinder clamp 312. The second lock cylinder clamp 3132 and the third lock cylinder clamp 3133 are movably connected to the lock cylinder clamp 312 and communicate with the lock cylinder cavity 3121, thereby abutting against the internal lock cylinder. The first lock cylinder clamp 3131 and the second lock cylinder clamp 3132 are connected by a spring, and the fourth lock cylinder clamp 3134 and the third lock cylinder clamp 3133 are connected by a spring. The pressing member 3135 is linked with the third lock cylinder clamp 3133.

[0126] The first lock cylinder clamp 3131 is fixedly provided with a first protrusion 31311, which is located outside the second lock cylinder clamp 3132. The first protrusion 31311 and the second lock cylinder clamp 3132 are connected by a spring. The fourth lock cylinder clamp 3134 is fixedly provided with a fourth protrusion 31341, and the third lock cylinder clamp 3133 is fixedly provided with a third protrusion 31331. The third protrusion 31331 is provided with a groove 31332, the opening of which faces the fourth lock cylinder clamp 3134. The fourth protrusion 31341 extends into the groove 31332 and is connected to the end face of the groove 31332 by a spring. When the spring is not under pressure, the second lock cylinder clamp 3132 and the third lock cylinder clamp 3133 are pressed against the lock cylinder clamp 312 based on the spring force to achieve the clamping of the lock cylinder.

[0127] The pressing member 3135 is fixed to the lock cylinder feeding base plate. The pressing member 3135 has an inclined surface 31351, the thickness of which gradually decreases as it approaches the third lock cylinder clamp 3133. The pressing member 3135 is inserted into the groove 31332, and the third lock cylinder clamp 3133 has an inclined surface that matches the inclined surface. When the lock cylinder feeding drive 311 drives the lock cylinder clamp 312 to move towards the lock cylinder feeding position, the position of the pressing member 3135 remains unchanged. The pressing member 3135 and the lock cylinder clamp 312 maintain relative movement. The lock cylinder clamp 312 moves while the pressing member 3135 remains stationary. The pressing member 3135 disengages from the third lock cylinder clamp 3133. In the closed state, the lock cylinder remains in a spring-clamped state until it moves to the lock cylinder loading position to prevent the lock cylinder from falling during movement. When the lock cylinder feeding drive 311 drives the lock cylinder clamp 312 away from the lock cylinder loading position, the position of the lifting member 3135 remains unchanged. The lifting member 3135 is inserted into the groove and cooperates with the third lock cylinder clamp 3133. The inclined surface of the lifting member 3135 gradually pulls the third lock cylinder clamp 3133 outward. The third lock cylinder clamp 3133 moves outward to compress the spring and disengage from the position that abuts against the lock cylinder. The position of the second lock cylinder clamp 3132 remains unchanged. At this time, the whole is in a relaxed state, and the lock cylinder falls from the lock cylinder cavity to proceed with the subsequent lock cylinder loading process.

[0128] like Figure 19 As shown, the lock cylinder sensing device 314 is used to sense the presence or absence of the lock cylinder clamp 312. When there is a lock cylinder in the lock cylinder clamp 312, the lock cylinder sensing device 314 sends a start signal to the lock cylinder delivery drive 311. When there is no lock cylinder in the lock cylinder clamp 312, the lock cylinder sensing device 314 issues an alarm or sends a warning to the control panel or other equipment. The lock cylinder sensing device 314 can use conventional photoelectric sensors, pressure sensors, etc. The sensing principle, structure, and installation can be determined according to actual needs.

[0129] like Figure 19 As shown, the lock cylinder pushing mechanism 32 includes a lower lock cylinder frame 320, a push cylinder drive, a twist cylinder drive, and a lock cylinder pin 324. The lower lock cylinder frame 320 is fixed on the shifting device 4, the push cylinder drive is fixed on the lower lock cylinder frame 320, the push cylinder drive is connected to the twist cylinder drive, and the lock cylinder pin 324 is connected to the twist cylinder drive. The push cylinder drive moves the lock cylinder pin 324 up and down to push the cylinder, and the twist cylinder drive rotates the lock cylinder pin 324 to rotate the lock cylinder.

[0130] The push core drive and the lock core feeding drive 311 have the same structure, realizing the reciprocating up and down movement of the twist core drive.

[0131] The core drive includes a rotary cylinder 323, which is connected to the core pusher via a mounting plate. The output shaft of the rotary cylinder 323 is connected to the core lock pin 324, and the end face of the core lock pin 324 is provided with a flat head.

[0132] The specific process of cutting lock cylinders is as follows:

[0133] The lock cylinder feeding mechanism 31 pushes the lock cylinder to the lock cylinder unloading position. At this time, the lock cylinder is located above the lock body and opposite the lock cylinder hole. The push cylinder drive drives the lock cylinder pin 324 to push the lock cylinder into the lock cylinder hole. At the same time, the flat head of the lock cylinder pin 324 is engaged in the key groove of the lock cylinder and remains stationary for positioning. After the vertical milling spring feeding mechanism 34 feeds the material, the rotary cylinder 323 drives the lock cylinder pin 324 to rotate the lock cylinder, so that the lock cylinder and the lock tongue are engaged.

[0134] like Figures 23-25 As shown, the vertical milling spring sorting mechanism 33 includes a vertical milling spring tube 331 and a sorting structure. The sorting structure includes a baffle 332, a sorting cylinder 339, a pusher 333, a pusher baffle 334, an upper pressure seat 335, and a material distribution base plate 330. The vertical milling spring tube 331 is connected to the baffle 332. The baffle 332 and the pusher 333 are respectively connected to the sorting cylinder 339. The pusher baffle 334 is movably connected to the pusher 333.

[0135] like Figure 24As shown, the upper pressure seat 335 is fixedly provided with a through hole 3351 and a horizontal groove 3352. The vertical milling spring tube 331 is set in the through hole 3351, and the baffle 332 is movably set in the horizontal groove 3352. The lower end face of the upper pressure seat 335 is provided with a stop groove 3353.

[0136] like Figure 25 As shown, the baffle 332 is provided with a baffle 3321, and the vertical milling spring tube 331 is provided with a side groove 3331. The baffle 3321 is inserted into or away from the side groove 3331. The sorting cylinder 339 drives the baffle 3321 to insert into the side groove 3331. At this time, the vertical milling spring located above is blocked by the baffle 3321 and cannot move down. The sorting cylinder 339 drives the sorting cylinder 339 to move in the opposite direction away from the side groove 3331. At this time, the vertical milling spring tube 331 can move smoothly in the vertical milling spring tube 331.

[0137] The height of the space between the baffle 332 and the vertical milling spring tube 331 is greater than the length of one vertical milling spring but less than the length of two vertical milling springs, so that the space can only accommodate one vertical milling spring.

[0138] like Figure 24 As shown, the sorting cylinder 339 is connected to the pusher 333 via the connector 336. The pusher 333 is provided with a material passage hole 3332. When the material passage hole 3332 is connected to the vertical milling spring tube 331, the vertical milling spring can fall from the vertical milling spring tube 331 into the material passage hole 3332. The sorting base plate 330 is provided with a discharge port 3301. The discharge port 3301 is connected to the feed pipe of the vertical milling spring feeding mechanism 34 via a pipe. When the material passage hole 3332 is connected to the discharge port 3301, the vertical milling spring... The material can fall into the discharge port 3301 through the material passage 3332 and enter the feed pipe. The pusher bar 333 is provided with a movable groove 3331. The material passage 3332 is connected to the movable groove 3331. The pusher bar baffle 334 is movably disposed in the movable groove 3331 and can move within the material passage 3332 and the movable groove 3331. During the process of the sorting cylinder 339 driving the pusher bar 333, the pusher bar baffle 334 is pushed by the end of the movable groove 3331 and moves synchronously with the pusher bar 333 for a certain distance.

[0139] like Figure 24 As shown, the push bar baffle 334 is provided with a lower convex plate 3341 and an upper convex plate 3342. The stop groove 3353 is located in the moving path of the upper convex plate 3342. The upper convex plate 3342 can enter the stop groove 3353 and is restricted by the end of the stop groove 3353. The other side of the upper convex plate 3342 is connected to the lower pressure seat 335 by a spring.

[0140] The material distribution base plate 330 serves as a support plate, and the sorting structure is installed on the material distribution base plate 330. The material distribution base plate 330 is connected to the frame 8.

[0141] The vertical milling sorting process is as follows:

[0142] like Figure 24As shown, this is the initial state. At this time, the bottom of the milling spring tube 331 abuts against the pusher bar 333, and the milling spring is isolated inside the milling spring tube 331. The stop bar 3321 is away from the side groove 3311. When sorting is required, the sorting cylinder 339 drives the baffle to move in the direction of the arrow. The baffle isolates one milling spring in the space. The pusher bar 333 moves synchronously in the direction of the arrow. The pusher bar 333 drives the pusher baffle 334 to move synchronously. The pusher baffle 334 moves and the spring is compressed. When the milling spring tube 331 is opposite to the through hole 3332, the milling spring falls into the through hole 3332. 32. The lower convex plate of the push bar baffle 334 is inserted into the material passage hole 3332, isolating the lower part of the material passage hole 3332. The vertical milling spring is located on the lower convex plate. The sorting cylinder 339 is driven in the reverse direction, the baffle is reset, the next vertical milling spring falls into the space, the push bar baffle 334 is reset, the push bar 333 continues to move forward, and the end of the movable groove drives the push bar baffle 334 to move with the push bar 333 until the upper convex plate abuts against the stop groove. At this time, the lower convex plate disengages from the material passage hole 3332, and the material passage hole 3332 is connected to the discharge port 3301. The vertical milling spring falls from the material passage hole 3332 into the discharge port 3301.

[0143] like Figure 24 As shown, the vertical milling cartridge sorting mechanism 33 also includes an air blowing structure 338, which is fixed on the material distribution base plate 330. The air blowing structure 338 is provided with an air blowing port 3381, which is located on the side and connected to the discharge port 3301. An air pump is connected to the air blowing port 3381 through an air pipe. When the air pump is started, it blows air through the air blowing port 3381 to the discharge port 3301. Under the action of the wind, the vertical milling cartridge is transported along the pipe to the vertical milling cartridge loading mechanism 34.

[0144] like Figure 26 As shown, the milling spring feeding mechanism 34 includes a milling spring frame 340 and a milling spring straightening structure and a milling spring feeding structure installed on the milling spring frame 340.

The lock body correction drive 341 is connected to the lock body correction pin 342, and the lock cylinder correction drive 343 is connected to the lock cylinder correction pin 344. The lock body correction pin 342 is opposite to the vertical milling spring hole of the lock body, and the lock cylinder correction pin 344 is opposite to the spring hole of the lock cylinder. The lock body correction pin 342 is driven by the lock body correction drive 341 to insert into the vertical milling spring hole, and the lock cylinder correction pin 344 is driven by the lock cylinder correction drive 343 to insert into the spring hole, thereby realizing the position correction of the lock body and the lock cylinder.

The lock body straightening front and rear slide rail 3412 is fixedly mounted on the vertical milling spring frame 340. The lock body straightening front and rear slider 3413 is slidably connected to the lock body straightening front and rear slide rail 3412. The lock body straightening front and rear slider 3413 is fixedly mounted on the vertical milling spring moving plate 3414. When the lock body straightening front and rear cylinder 3411 is activated, it drives the vertical milling spring moving plate 3414 to move back and forth.

[0147] like Figure 26 As shown, the lock body straightening pin 342 is fixedly mounted on the upper milling spring guide 3421. The upper milling spring guide 3421 is fixedly connected to the milling spring moving plate 3414 through the upper milling spring guide fixing member 3422. The lock body straightening cylinder 3411 is activated to drive the lock body straightening pin 342 to move back and forth. The lock body straightening pin 342 is driven by the lock body straightening drive 341 to insert into the milling spring hole of the lock body, thereby correcting the position of the lock body and facilitating the subsequent milling spring pushing.

[0148] like Figure 26 As shown, the lock cylinder correction drive 343 includes a lock cylinder correction cylinder 3431, which is fixedly mounted on the vertical milling spring moving plate 3414. The output shaft of the lock cylinder correction cylinder 3431 is fixedly connected to the lock cylinder correction pin 344. The lock cylinder correction pin 344 slides through the upper vertical milling spring guide 3421. When the lock cylinder correction cylinder 3431 is activated, it drives the lock cylinder correction pin 344 to move back and forth. Driven by the lock cylinder correction cylinder 3431, the lock cylinder correction pin 344 is inserted into the spring hole of the lock cylinder, thereby correcting the position of the lock cylinder and facilitating the subsequent vertical milling spring pushing.

[0149] like Figure 26 As shown, the milling cartridge loading structure includes a milling cartridge loading drive 345, a milling cartridge feeding drive 346, and a milling cartridge punch 347. The milling cartridge loading drive 345 is connected to the milling cartridge sorting mechanism 33, and the milling cartridge feeding drive 346 is connected to the milling cartridge punch 347. The milling cartridge loading drive 345 pushes the milling cartridges from the milling cartridge sorting mechanism 33 to the loading position, and the milling cartridge feeding drive 346 starts to push the milling cartridges into the milling cartridge holes through the milling cartridge punch 347.

[0150] like Figure 26As shown, the milling cartridge loading drive 345 includes a milling cartridge loading cylinder 3451, an upper milling cartridge pusher 3452, and a milling cartridge feeding guide 3453. The milling cartridge loading cylinder 3451 and the milling cartridge feeding guide 3453 are fixedly mounted on the milling cartridge moving plate 3414. The milling cartridge feeding guide 3453 has a milling cartridge cavity inside. The upper milling cartridge pusher 3452 is fixedly connected to the milling cartridge loading cylinder 3451 and inserted into the milling cartridge cavity. The milling cartridge feeding guide 3453 has a milling cartridge feed pipe 3454. The milling cartridges of the milling cartridge sorting mechanism enter the milling cartridge cavity along the milling cartridge feed pipe 3454. The milling cartridge loading cylinder 3451 is activated to push the upper milling cartridge pusher 345. The upper milling cartridge pusher 345 moves to push the milling cartridge into the milling cartridge feed port.

[0151] like Figure 26 As shown, the milling cartridge feed drive 346 includes a milling cartridge feed cylinder 3461 and a milling cartridge feed plate 3462. The milling cartridge feed plate 3462 is provided with a milling cartridge feed port, which is connected to the milling cartridge cavity. The upper milling cartridge pusher 345 moves to push the milling cartridge into the milling cartridge feed port. The milling cartridge punch 347 slides with the upper milling cartridge pusher 345 and faces the milling cartridge feed port. The milling cartridge feed cylinder 3461 starts and drives the milling cartridge punch 347 to push the milling cartridge located in the milling cartridge feed port through the upper milling cartridge guide 3421 and into a certain milling cartridge hole of the lock body.

[0152] The specific process of loading springs into the vertical milling machine is as follows:

[0153] After the lock cylinder is loaded at the lock cylinder loading station, the milling spring is loaded. At this time, the lock body to be milled is located at the lock cylinder loading station, which is also the milling spring loading station. That is, the lock body is connected to the milling spring loading mechanism 34, and the milling spring loading mechanism 34 is located above the lock body discharge mechanism 14. The lock body straightening pin 342 is driven by the lock body straightening drive 341 to insert into the milling spring hole of the lock body. The lock body straightening pin 342 can only be inserted into the milling spring hole when the lock body is in the correct position, thus correcting the lock body. Then, the lock cylinder straightening pin 344 is driven by the lock cylinder straightening drive 343 to insert into the spring hole of the lock cylinder. Based on the correction of the lock body, the position of the lock cylinder is corrected. After the position of the lock body and the lock cylinder is corrected, the milling spring sorting mechanism 33 starts to convey a milling spring to the delivery station. The milling spring guide 3453 and the milling spring loading cylinder 3451 are activated to push the upper milling spring pusher 345. The upper milling spring pusher 345 moves to push the milling spring into the milling spring inlet. The milling spring loading cylinder 3461 is activated to drive the milling spring punch 347 to push the milling spring located at the milling spring inlet through the upper milling spring guide 3421 into a certain milling spring hole of the lock body. The lower lock body cylinder is activated, and the push plate at the end of its output shaft moves up. The push plate supports the lock body upward. The lock body clamping mechanism 13 releases the lock body. The lower lock body cylinder drives the lock body to move down a set distance in sequence and then clamps the lock body through the lock body clamping mechanism 13. The set distance is the distance between the adjacent milling springs. At this time, the milling spring loading slot operation is performed until all milling springs are loaded. Then the lock body unloading operation is performed.

[0154] This invention enables the assembly of double-tongue lock tongues through a lock tongue assembly device, which not only improves the high-precision assembly of lock tongues and enhances the assembly quality, but also achieves efficient assembly of lock tongues and improves assembly efficiency. If necessary, it can be modified to adapt to single-tongue assembly.
