Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a high-efficiency deburring device for key posts of combination locks. Background Technology

[0002] Key pins are a component of mechanical combination locks. After initial production, their surfaces need to be deburred. This process requires a stamping deburring device. Existing stamping deburring devices require manual loading. Since the key pins are small and numerous, placing them on the fixture table in the correct orientation requires slow and careful handling, resulting in low loading efficiency and consequently, low overall deburring efficiency. This needs to be improved. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this utility model provides a high-efficiency deburring device for keypad buttons on combination locks. The device includes an automatic feeding mechanism, a mounting frame, a stamping table with stamping holes, and a stamping mechanism. Both the stamping table and the stamping mechanism are mounted on the mounting frame. The automatic feeding mechanism includes a feeding vibratory feeder, a feeding track connected to the vibratory feeder, a drive cylinder for driving the stamping table, a feeding mounting platform, and a proximity switch. The feeding mounting platform is fixedly mounted on the mounting frame and located below the stamping mechanism. The feeding mounting platform has a through slot matching the stamping table, and a pair of mounting beams are provided on the two side walls of the through slot. A through hole communicating with a through slot is opened on one side wall of the mounting platform. The drive cylinder is fixedly installed on the side wall of the loading mounting platform and the piston rod passes through the through hole and is connected to the stamping platform. A loading notch communicating with the through slot is opened on the loading mounting platform. The end of the loading track fits and aligns with the loading notch. A loading port matching the loading notch is opened at the position of the stamping hole on the stamping platform. One side of the pair of mounting beams has a passage for the key post to fall after stamping. The proximity switch is installed on the loading mounting platform and its position is aligned with the loading port. The proximity switch is electrically connected to the drive cylinder and the stamping mechanism through a PLC controller.

[0004] Using the above technical solution, the key posts to be deburred are poured into the vibratory feeder in batches. After the device is started, the key posts are transferred to the feeding track by the vibratory feeder, and then transferred to the feeding notch along the feeding track. After the key posts are in the feeding notch, they are squeezed by the key posts that enter the feeding notch later and passively moved to the feeding port of the stamping table and finally fall into the stamping hole. At this time, the proximity switch senses the presence of key posts in the stamping hole and sends a feedback signal to the drive cylinder. The drive cylinder starts and controls the stamping table to move along a pair of mounting beams to the bottom of the stamping mechanism. Then the stamping mechanism starts and punches the key posts out of the stamping hole and drops them through the outlet, completing the deburring work on the periphery of the key posts. Afterwards, the stamping mechanism and the drive cylinder reset in sequence and repeat the operation, realizing the automatic feeding and automatic deburring of key posts, replacing the traditional manual feeding and improving production efficiency.

[0005] A further feature of this invention is that an installation platform is provided on one side of the feeding notch on the feeding mounting platform, a micro motor is provided on the installation platform, a lever is fixed on the rotating shaft of the micro motor, and the micro motor is also electrically connected to the drive cylinder and the stamping mechanism through a PLC controller.

[0006] By adopting the above technical solution, since an installation platform is provided on one side of the feeding notch on the feeding mounting platform, and a micro motor is provided on the installation platform, a lever is fixed on the rotating shaft of the micro motor, and the micro motor is also electrically connected to the drive cylinder and the stamping mechanism through a PLC controller, the lever can be driven to rotate by the micro motor rotating at regular intervals, so as to push the key post located in the feeding notch into the feeding port of the stamping table, thus solving the problem that the key post in the feeding notch can only be moved by the extrusion of subsequent key posts, and further improving the feeding efficiency.

[0007] A further feature of this invention is that the surface of the mounting platform is an inclined surface.

[0008] By adopting the above technical solution, since the platform of the mounting table is inclined, the lever can rotate obliquely. When rotating, it can precisely move only one key post in the feeding notch, avoiding the situation where the key post jams the lever.

[0009] A further feature of this invention is that the end of the lever is provided with several soft bristles.

[0010] By adopting the above technical solution, since the end of the lever is provided with several soft bristles, the situation of the lever being stuck by the key post can be further avoided.

[0011] A further feature of this invention is that a discharge hopper is provided on the mounting frame below the feeding mounting platform.

[0012] By adopting the above technical solution, since a discharge hopper is provided on the mounting frame below the loading mounting platform, the key post can fall along the discharge hopper after being punched down by the stamping mechanism and falling through the through port. Only a collection device needs to be set up below the discharge hopper to collect the key post, further improving the complete deburring process of the key post. Attached Figure Description

Detailed Implementation

[0017] like Figure 1-3As shown, a high-efficiency deburring device for keypad buttons of a combination lock includes an automatic feeding mechanism 1, a mounting frame 2, a stamping table 4 with stamping holes 3, and a stamping mechanism. Both the stamping table and the stamping mechanism are mounted on the mounting frame. The automatic feeding mechanism includes a feeding vibratory feeder 5, a feeding track 6 connected to the vibratory feeder, a drive cylinder 7 for driving the stamping table, a feeding mounting platform 8, and a proximity switch 9. The feeding mounting platform is fixedly mounted on the mounting frame and located below the stamping mechanism. The feeding mounting platform has a through groove 10 that matches the stamping table. A pair of mounting beams 11 are provided on the two side walls of the through groove. A through hole communicating with a through slot is opened on the side wall. The drive cylinder is fixedly installed on the side wall of the loading mounting platform and the piston rod passes through the through hole and is connected to the stamping platform. A loading notch 12 communicating with the through slot is opened on the loading mounting platform. The end of the loading track fits and aligns with the loading notch. A loading port 13 matching the loading notch is opened at the position of the stamping hole on the stamping platform. One side of the pair of mounting beams has a passage 14 for the key post to fall after stamping. The proximity switch is installed on the loading mounting platform and its position is aligned with the loading port. The proximity switch is electrically connected to the drive cylinder and the stamping mechanism through a PLC controller.

[0018] The key posts to be deburred are poured into the vibratory feeder in batches. After the device is started, the key posts 21 are transferred to the feeding track by the vibratory feeder, and then transferred to the feeding notch along the feeding track. After the key posts are in the feeding notch, they are squeezed by the key posts that enter the feeding notch later and passively moved to the feeding port of the stamping table and finally fall into the stamping hole. At this time, the proximity switch senses the presence of key posts in the stamping hole and sends a feedback signal to the drive cylinder. The drive cylinder starts and controls the stamping table to move along a pair of mounting beams to the bottom of the stamping mechanism. Then the stamping mechanism starts and punches the key posts out of the stamping hole and drops them through the outlet, completing the deburring work on the periphery of the key posts. Afterwards, the stamping mechanism and the drive cylinder reset in sequence and repeat the operation, realizing the automatic feeding and deburring of key posts, replacing the traditional manual feeding and improving production efficiency.

[0019] A mounting platform 15 is provided on one side of the loading notch on the loading mounting platform. A micro motor 16 is provided on the mounting platform. A lever 17 is fixed on the rotating shaft of the micro motor. The micro motor is also electrically connected to the drive cylinder and the stamping mechanism through a PLC controller.

[0020] Because a mounting platform is provided on one side of the feeding notch on the feeding mounting platform, and a micro motor is provided on the mounting platform, and a lever is fixed on the rotating shaft of the micro motor, the micro motor is also electrically connected to the drive cylinder and the stamping mechanism through a PLC controller, the lever can be driven to rotate by the micro motor rotating at regular intervals, so as to push the key post located in the feeding notch into the feeding port of the stamping table, which solves the problem that the key post in the feeding notch can only be moved by the extrusion of subsequent key posts, and further improves the feeding efficiency.

[0021] The mounting platform has an inclined surface.

[0022] Because the mounting platform has an inclined surface, the lever can rotate at an angle. When rotating, it can precisely move only one key post in the feeding notch, avoiding the key post from jamming the lever.

[0023] The end of the lever is provided with several soft bristles 18.

[0024] Because the end of the lever is provided with several soft bristles, the situation where the lever gets stuck by the key post can be further avoided.

[0025] The mounting frame is provided with a discharge hopper 19 located below the loading mounting platform.

[0026] Since the mounting frame is equipped with a discharge hopper located below the loading mounting platform, the key post, after being punched down by the stamping mechanism and falling through the through-hole, can fall along the discharge hopper. Only a collection device needs to be set up below the discharge hopper to collect the key post, further improving the complete deburring process of the key post.
