Description

Technical Field

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

[0002] The lock plate is a component of a mechanical combination lock. After the initial production is completed, its surface and the mounting holes for the keypad need to be deburred. This process requires a stamping deburring device. The existing stamping deburring device involves manually placing the lock plate on the fixture, starting the stamping mechanism to deburr, and then manually removing the lock plate after the stamping deburring is completed. The entire process requires manual assistance, resulting in limited production efficiency, which urgently needs improvement. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this utility model provides a highly efficient deburring device for producing combination lock plates. The device includes a mounting platform, a fixture platform, and a stamping deburring mechanism. Both the fixture platform and the stamping deburring mechanism are mounted on the mounting platform. An automatic feeding device is provided on the mounting platform, and an automatic loading / unloading device is provided on the fixture platform. The automatic feeding device includes a mounting frame, a pair of stacking limit plates, a feeding platform, a feeding platform drive mechanism, and a proximity switch assembly. The mounting frame, the pair of stacking limit plates, and the proximity switch assembly are all mounted on the mounting platform. A stacking opening matching the shape and size of the lock plate is formed between the pair of stacking limit plates. One end of the feeding platform is fixedly connected to the feeding platform drive mechanism. A transfer slot matching the shape and size of the lock plate is opened on the feeding platform. The proximity switch assembly is respectively mounted on the mounting frame and the feeding platform, and its position is relative to the stacking limit plates and the transfer slot. The automatic loading and unloading device includes an end mounting plate, a pair of mounting side plates, a feeding push plate with a feeding push block, a discharging push plate with a discharging push rod, a pair of connecting rods, and a loading and unloading drive cylinder. The pair of mounting side plates are symmetrically arranged on the mounting platform at positions on both sides of the fixture table. The end mounting plate is fixedly arranged on the mounting platform at a position near the end of the fixture table. Each of the pair of mounting side plates has a sliding through hole that matches the connecting rod. The pair of connecting rods are both arranged in the sliding through hole and their two ends are respectively connected to the feeding push plate and the discharging push plate. The loading and unloading drive cylinder is fixedly arranged on the end mounting plate and its piston rod is connected to the discharging push plate. One end of the transfer placement slot has a through notch for the feeding push block to pass through. The stamping deburring mechanism, the feeding table drive mechanism, the proximity switch group, and the loading and unloading drive cylinder are all electrically connected through a PLC controller.

[0004] Using the above technical solution, the combination lock plates to be deburred are placed in batches between a pair of stacking limit plates. The bottom lock plate falls first into the transfer placement slot of the feeding table. After the equipment is started, the proximity switch group on the mounting frame and the feeding table is triggered, controlling the feeding table drive mechanism to start and push the feeding table towards the clamping table until the transfer placement slot is aligned with the entrance of the clamping table. Then, the loading and unloading drive cylinder starts and retracts, driving the feeding pusher plate to move towards the entrance of the clamping table. During the movement, the feeding pusher plate passes through the transfer placement slot and pushes the lock plates in the transfer placement slot towards the entrance of the clamping table until the lock plates are pushed onto the clamping table and stop moving. After that, the feeding table resets, the stamping and deburring mechanism starts and presses down to deburr the mounting holes of the lock plate on the fixture table. After completion, the stamping and deburring mechanism resets, the loading and unloading drive cylinder starts again and extends, controlling the discharge push plate to extend along the direction of the fixture table entrance and drive the discharge push rod to push the lock plate out of the fixture table, completing the loading, deburring and unloading of a single lock plate. After the feeding table resets, the next lock plate automatically falls into the transfer placement slot, completing one cycle. This eliminates the need for manual clamping and unloading of lock plates on the fixture table. Workers only need to place the lock plates in batches into a pair of stacking limit plates, improving the overall deburring efficiency.

[0005] A further feature of this invention is that the feeding platform driving mechanism includes a feeding driving cylinder, a mounting slide rail, and a connecting slider. The feeding driving cylinder and the mounting slide rail are both mounted on a mounting frame. The connecting slider is located at the bottom of the feeding platform and slides in cooperation with the mounting slide rail. The piston rod of the feeding driving cylinder is connected to the end of the feeding platform.

[0006] By adopting the above technical solution, since the feeding table driving mechanism includes a feeding driving cylinder, an installation slide rail and a connecting slider, the feeding driving cylinder and the installation slide rail are both set on the mounting frame, the connecting slider is set at the bottom of the feeding table and slides with the installation slide rail, the piston rod of the feeding driving cylinder is connected to the end of the feeding table, and the feeding table is moved on the installation slide rail by controlling the feeding driving cylinder to transfer the locking plate between the feeding push plate and the inlet of the clamping table, thus realizing the automatic feeding of the locking plate.

[0007] A further feature of this invention is that a discharge hopper is provided on the mounting platform below the clamping table.

[0008] By adopting the above technical solution, since a discharge hopper is provided on the mounting platform below the clamping table, the lock plate can be recycled simply by setting up a collection box below the discharge hopper, which further improves the deburring process of the lock plate.

[0009] A further feature of this invention is that guide chamfers are provided at the ends of both side walls of the fixture platform located at the entrance.

[0010] By adopting the above technical solution, since the ends of the two side walls at the entrance of the fixture platform are provided with guide chamfers, it is further ensured that the locking plate can be accurately pushed into the entrance of the fixture platform.

The pair of mounting side plates are symmetrically arranged on the mounting platform at positions on both sides of the fixture table. The end mounting plate is fixedly arranged on the mounting platform at a position near the end of the fixture table. Each of the pair of mounting side plates has a sliding through hole 20 that matches the connecting rod. The pair of connecting rods are both arranged in the sliding through hole and their two ends are respectively connected to the feeding push plate and the discharge push plate. The loading / unloading drive cylinder is fixedly arranged on the end mounting plate and its piston rod is connected to the discharge push plate. One end of the transfer placement slot has a passage notch 21 for the feeding push block to pass through. The stamping deburring mechanism, the feeding table drive mechanism, the proximity switch group, and the loading / unloading drive cylinder are all electrically connected through a PLC controller.

[0017] The combination lock plates to be deburred are placed in batches between a pair of stacking limit plates. The bottom lock plate 27 falls first into the transfer placement slot of the feeding table. After the equipment is started, the proximity switch group on the mounting frame and the feeding table is triggered, controlling the feeding table drive mechanism to start, pushing the feeding table towards the fixture table until the transfer placement slot is aligned with the entrance of the fixture table. Then, the loading and unloading drive cylinder starts and retracts, driving the feeding pusher plate towards the entrance of the fixture table. During the movement, the feeding pusher plate passes through the transfer placement slot and pushes the lock plates in the transfer placement slot towards the entrance of the fixture table until the lock plates are pushed onto the fixture table and stop moving. After the rear feeding table resets, the stamping and deburring mechanism starts and presses down to deburr the mounting holes of the lock plate on the fixture table. After completion, the stamping and deburring mechanism resets, the loading and unloading drive cylinder starts again and extends, controlling the discharge push plate to extend along the direction of the fixture table entrance and drive the discharge push rod to push the lock plate out of the fixture table, completing the loading, deburring and unloading of a single lock plate. After the feeding table resets, the next lock plate automatically falls into the transfer placement slot, completing one cycle. This eliminates the need for manual clamping and unloading of lock plates on the fixture table. Workers only need to place the lock plates in batches into a pair of stacking limit plates, improving the overall deburring efficiency.

[0018] The feeding platform drive mechanism includes a feeding drive cylinder 22, a mounting slide rail 23, and a connecting slider 24. The feeding drive cylinder and the mounting slide rail are both mounted on a mounting frame. The connecting slider is located at the bottom of the feeding platform and slides in cooperation with the mounting slide rail. The piston rod of the feeding drive cylinder is connected to the end of the feeding platform.

[0019] Since the feeding platform drive mechanism includes a feeding drive cylinder, an installation slide rail, and a connecting slider, the feeding drive cylinder and the installation slide rail are both mounted on the mounting frame. The connecting slider is located at the bottom of the feeding platform and slides in cooperation with the installation slide rail. The piston rod of the feeding drive cylinder is connected to the end of the feeding platform. By controlling the feeding platform to move on the installation slide rail through the feeding drive cylinder, the locking plate is transferred to the inlet between the feeding push plate and the clamping table, thus realizing the automatic feeding of the locking plate.

[0020] A discharge hopper 25 is provided on the mounting platform below the clamping table.

[0021] Since a discharge hopper is provided on the mounting platform below the clamping table, the lock plate can be recycled simply by setting up a collection box below the discharge hopper, which further improves the deburring process of the lock plate.

[0022] The ends of both sides of the fixture platform at the entrance are provided with guide chamfers 26.

[0023] Since the ends of the two side walls at the entrance of the fixture platform are provided with guide chamfers, it is further ensured that the locking plate can be accurately pushed into the entrance of the fixture platform.
