[0023] Example 1:
[0024] like Figures 1-4 As shown, an automatic lock cylinder assembly device includes a lock cylinder mechanism 31 and a lower lock cylinder mechanism 32. 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 clamping structure 313, and a lock cylinder sensing device 314. The lock cylinder feeding drive 311 is mounted on the lock cylinder feeding frame 310. The lock cylinder feeding drive 311, the lock cylinder clamping structure 313 are connected to the lock cylinder clamp 312, and the lock cylinder sensing device 314 is disposed on the lock cylinder clamp 312. The lock cylinder clamp 312 clamps the lock cylinder.
[0025] The lock cylinder clamping structure 313 is used to clamp and release the lock cylinder inside the lock cylinder clamp 312, and the lock cylinder drive 311 drives the lock cylinder clamp 312 to move linearly back and forth.
[0026] 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, a slide rail 3112, and a slider 3113. The lock cylinder delivery cylinder 3111 and the slide rail 3112 are fixed on the lock cylinder delivery frame 310. The slider 3113 is slidably connected to the slide rail 3112. The lock cylinder clamp 312 is fixed on the slider 3113 through the lock cylinder delivery base plate. The lock cylinder delivery cylinder 3111 is connected to the lock cylinder delivery base plate. When the lock cylinder delivery cylinder 3111 is activated, it drives the lock cylinder clamp 312 to slide along the slide rail 3112.
[0027] 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.
[0028] The lock cylinder clamping structure 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.
[0029] 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.
[0030] 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.
[0031] 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.
[0032] The lower lock cylinder mechanism 32 includes a lower lock cylinder frame 320, a push cylinder drive, a twist cylinder drive, and a lock cylinder pin 324. The push cylinder drive is fixed on the lower lock cylinder frame 320 and is connected to the twist cylinder drive. 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.
[0033] The push core drive and the lock core delivery drive 311 have the same structure, realizing the reciprocating up and down movement of the twist core drive.
[0034] 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.
[0035] The specific process of cutting lock cylinders is as follows:
[0036] The cylinder feeding mechanism 31 pushes the lock cylinder to the lower lock cylinder mechanism 32. At this time, the lock cylinder is located above the lock body and opposite the lock cylinder hole. The cylinder pusher 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 is loaded, the feeding cylinder 323 drives the lock cylinder pin 324 to rotate the lock cylinder, so that the lock cylinder and the bolt are engaged.
[0037] This invention achieves double-tongue lock tongue assembly through a lock tongue assembly device, which not only improves the high-precision assembly of the lock tongue and enhances the assembly quality, but also achieves efficient assembly of the lock tongue and improves assembly efficiency. If necessary, it can be modified to adapt to single-tongue assembly.
[0038] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
