Description

Technical Field

[0001] The utility model relates to the technical field of metal lock case processing, in particular to a tapping device for metal lock case production. Background Art

[0002] A metal lock case is a metal product used to protect the lock cylinder and secure it to a door or device. Its primary functions are to protect against dust, water, and corrosion, while also ensuring the mechanical properties of the lock cylinder are protected from external influences. Metal lock cases are typically made of materials such as iron, stainless steel, and copper, offering excellent hardness and durability. Designed to tightly encase the lock cylinder, the case connects to the door or device via screws or other fasteners to ensure its stability. Tapping machines are machine tools used to create internal threads on various materials and are widely used in machinery, mold manufacturing, and automotive manufacturing. Tapping machines are categorized by drive mode: manual, electric, pneumatic, and hydraulic; by the number of spindles: single-spindle and multi-spindle; and by the processing type: in-mold tapping machines and universal tapping machines. Automatic tapping machines are widely used for their high degree of automation, ease of operation, and high efficiency. Their primary function is to create precise internal threads on workpieces, facilitating the fastening of externally threaded parts such as bolts and screws. Their operating principle is to remove material through the rotation and feed motion of the tool to form the desired thread shape.

[0003] However, the lack of precise positioning during the tapping process in some existing metal lock cases will lead to initial deviations in processing. The tapping process requires extremely high precision. Any slight positional deviation may lead to inaccurate thread size and reduced thread quality. At the same time, if the lock case moves or loosens during processing, it may also cause tool damage or breakage, increasing processing risks and costs. Therefore, the metal lock case cannot be firmly clamped and fixed. The vibration and cutting force during the processing may cause the lock case to shift, thereby affecting the accuracy of tapping. This shift not only affects the quality of the thread, but may also cause additional scratches or indentations on the lock case, reducing the overall appearance and performance of the product. Therefore, in response to the above shortcomings, a tapping device for metal lock case production is proposed to solve the above problems. Utility Model Content

[0042] Working Principle: When the metal lock case needs to be processed, the unprocessed metal lock case can be manually placed on top of the loading conveyor belt 3. The drive motor 4 can then be started to drive the loading conveyor belt 3 to transport the metal lock case. When the metal lock case is transported to the right side of the loading conveyor belt 3, the positioning cylinder 5 can be activated to drive the push plate to move, thereby positioning and aligning the metal lock case. The slide cylinder 10 can then be activated, which drives the sliding plate 11 to move, thereby driving the cylinder 14 to change position, and then one of the positioning blocks 16 will be aligned above the metal lock case.

[0043] Then the cylinder 14 can be started, and the cylinder 14 can be used to drive the transport jig 15 and the positioning block 16 to move downward, thereby locking the metal lock shell. Then the slide rail cylinder 10 can be controlled to drive the sliding vertical plate 11 to move, and the metal lock shell can be transported to the top of the mounting plate 17 and unlocked. Then the limit cylinder 18 can be started, and the fixed clamping claw 19 can be controlled by the limit cylinder 18 to achieve the positioning and clamping of the metal lock shell. Then the tapping operation of the metal lock shell can be achieved by controlling the tapping machine body 21. After the tapping is completed, the slide rail cylinder 10 can be started again to drive the sliding vertical plate 11 to move, and then the cylinder 14 can be controlled to lock the metal lock shell that has completed the tapping operation through the positioning block 16;

[0044] The metal lock case is then transported to the top of the feed conveyor 23, where it can be unlocked. The metal lock case is then unloaded by the feed conveyor 23, dropping onto the top of the buffer plate 28. The weight of the metal lock case causes the buffer plate 28 to rotate, causing the rotating sleeve 27 to rotate outside the fixed shaft 26. This forces the sliding plate 29 downward, which in turn causes the sleeve 32 to move downward. This compresses the spring 35, cushioning the impact of the metal lock case's fall. Finally, it falls into the collection bin 37 for collection.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
