Description

Technical Field

[0001] The invention relates to the technical field of hardware product processing, in particular to a slotting device for processing hardware product blanks. Background Art

[0002] Hardware products refer to auxiliary and accessory manufactured goods used in daily life and industrial production. Early on, they were so named because they were primarily made of metal materials such as gold, silver, copper, iron, and tin. Today, in addition to metal materials, non-metallic materials such as plastics and fiberglass are also widely used. As a vital tool for human survival and development, hardware products have continued to expand in variety with the refinement of socioeconomic divisions. Slotting is a common process in hardware processing. Traditional slotting devices perform operations through reciprocating motion. However, when faced with workpieces with circular arcs or irregular surfaces, conventional linear slotting cannot meet processing requirements, resulting in limitations in the processing of irregular hardware parts. Therefore, it is necessary to develop a specialized slotting device suitable for processing irregular blanks to improve process adaptability.

[0003] In the prior art, a patent document with application publication number CN117359001A provides a slotting device for processing hardware blanks. The device cooperates with a machining rotation component and a slotting movement component to rotate the hardware during slotting operations, slotting the circumferential surface of the hardware, and moving the slotting head up and down to slot the hardware. The position distance of the slotting head can be adjusted during slotting to control the slotting thickness of the hardware.

[0004] However, the device still has the following problems: when the device drives the rotating disk to rotate through the rotating motor and the rotating shaft, it will drive the fixed motor to rotate along with the rotating shaft, which will undoubtedly cause the peripheral wires of the fixed motor to become entangled. Even if a conductive slip ring is set, it will need to be replaced for a long time due to the wear of the conductive slip ring, which is obviously very inconvenient. Summary of the Invention

[0022] A first limiting ring 301 is fixedly installed on the periphery of the cylinder body of the first cylinder 3 , and the first driving rod 28 is rotatably installed in the first limiting ring 301 . A second limiting ring 302 is fixedly installed on the periphery of the output shaft of the first cylinder 3 , and the movable seat 32 is rotatably installed in the second limiting ring 302 .

[0024] The specific working principle and method of use of the present invention are explained in detail below: When in use, a hardware workpiece is placed on the upper end of the first rotating disk 21, and the first cylinder 3 is started. The first cylinder 3 drives the movable seat 32 to move through its output shaft, and the moving movable seat 32 is connected to the internal threaded sleeve 34 through the threaded connection between the external threaded sleeve 323 and the internal threaded sleeve 34, wherein the thread helix angle λ is greater than the friction angle ρ, and the thread self-locking adjustment is released, so that the external threaded sleeve 323 that moves up and down can drive the internal threaded sleeve 34 to rotate. Finally, through the sliding connection between the limiting slide rail 25 and the first limiting slider 23 and between the driving slide groove 26 and the driving slide groove 26, the rotating second rotating disk 22 can drive the positioning clamp 2 to retract inward, thereby achieving the effect of positioning the hardware workpiece; When processing a hardware workpiece, the first drive motor 27 is started.

Secondly, the first drive motor 27 can drive the first drive rod 28 to rotate through its output shaft and bevel gear set. Since the first limit slot 311 and the first limit rod 321 and the second limit slot 331 and the second limit rod 322 are always respectively plugged into each other, and then through the first limit ring 301 and the second limit ring 302, the first drive rod 28 can drive the second drive rod 33 to rotate on one side of the first cylinder 3, thereby achieving the effect of driving the hardware workpiece to rotate.

[0025] It is worth noting that there are multiple positioning clamps 2, and the lower ends of the multiple positioning clamps 2 are fixedly installed with the first limit slider 23 and the second limit slider 24 in sequence. The upper end of the first rotating disk 21 is provided with a limit slide rail 25 that is slidably connected to each first limit slider 23, and the upper end of the second rotating disk 22 is provided with a driving slide groove 26 that is slidably connected to the second limit slider 24.

[0026] An exhaust chamber 4 is opened on the periphery of the workbench 1, and a filter cartridge 41 is installed in the exhaust chamber 4. A second drive motor 44 is fixedly installed on the inner wall of the workbench 1. A guide vane 442 is rotatably installed on the upper side of the inner cavity of the exhaust chamber 4. The output shaft of the second drive motor 44 is connected to the guide vane 442.

[0027] An air guide ring 42 is fixedly installed on the inner wall of the workbench 1. A through hole 43 is opened on the inner wall of the workbench 1 and is interconnected with the air guide ring 42 and the exhaust chamber 4. An air guide chamber 421 is opened on the upper end of the positioning clamp 2. An air guide hole 422 is opened in the first limit slider 23 and the second limit slider 24 and is interconnected with the air guide chamber 421. A telescopic sleeve 423 that is plugged into and connected to the air guide hole 422 and the air guide ring 42 is fixedly installed.

[0028] A rotating shaft sleeve 441 is fixedly installed on the upper end of the guide blade 442 and is rotatably connected to the upper side of the inner cavity of the exhaust chamber 4. The upper end of the rotating shaft sleeve 441 is meshed with the output shaft of the second drive motor 44 through a bevel gear set. A rotating shaft rod 451 is provided in the rotating shaft sleeve 441. A cleaning brush 45 is rotatably installed on the lower end of the rotating shaft rod 451. The cleaning brush 45 is in contact with the inner wall of the filter cartridge 41.

[0029] An internal gear 462 is fixedly mounted on the upper end of the rotating sleeve 441, an outer gear ring 461 is fixedly mounted on the upper end of the rotating shaft 451, a planetary gear 463 is rotatably mounted on the inner wall of the workbench 1 through a bracket, the planetary gear 463 is meshed and connected between the internal gear 462 and the outer gear ring 461, a second cylinder 46 is fixedly mounted on the inner wall of the workbench 1, a third limiting ring 464 is fixedly mounted on the lower end of the second cylinder 46 through its output shaft, and the outer gear ring 461 is rotatably mounted in the third limiting ring 464.

[0030] When it is necessary to collect the iron chips generated by slotting of hardware workpieces, the second drive motor 44 is started, and the guide vane 442 can be driven to rotate through its output shaft and bevel gear set, so as to guide the air inside the exhaust chamber 4, thereby sequentially passing through the air guide hole 422, the telescopic sleeve 423, the air guide ring 42 and the through hole 43, and the iron chips generated by slotting of the hardware workpiece can be guided into the filter cartridge 41, so that the iron chips can be collected. Since the filter cartridge 41 is threadedly connected to the exhaust chamber 4, the iron chips can be recovered by removing the filter cartridge 41; When it is necessary to clean the iron filings blocked on the inner wall of the filter cartridge 41, the second cylinder 46 is started, and the outer ring gear 461 is driven to move through its output shaft and the third limiting ring 464, so that the outer ring gear 461 and the planetary gear 463 are engaged with each other, so that when the second drive motor 44 drives the guide vane 442 to rotate, the guide vane 442 can drive the inner gear 462 to rotate, and the meshing connection between the planetary gear 463 and the inner gear 462 and the outer ring gear 461 can drive the cleaning brush 45 to decelerate the rotation on the inner wall of the filter cartridge 41, thereby cleaning the iron filings blocked on the inner wall of the filter cartridge 41.
