Description

Technical Field

[0001] This utility model relates to the field of auxiliary technology for processing plumbing fittings, specifically to an auxiliary tooling for a multi-station CNC machining center for processing plumbing fittings. Background Technology

[0002] The market demand for plumbing fittings is booming, but traditional processing methods are inefficient, lack precision, and are costly in terms of labor. To address this, rotary multi-station automated machining centers have emerged. By integrating drilling, tapping, chamfering, and other processes, they can produce dozens of products per minute at high speed. This not only significantly improves production efficiency and processing consistency but also substantially reduces unit costs and reliance on skilled workers, providing plumbing fittings manufacturers with an efficient solution to enhance their core competitiveness.

[0003] This type of device has the advantage of multi-station synchronous processing for regular connectors. The processing speed is fast and it does not rely on human assistance. However, during the processing in the CNC machining center, the large production capacity also leads to a large output of workpiece debris. In addition, areas that are not cooled in time will produce smoke. Existing devices usually require manual cleaning and cannot handle these contaminants autonomously. This requires labor and the cleaning cannot be completed in real time, so the auxiliary functions of the device need to be improved. Utility Model Content

[0013] Compared with the prior art, this utility model provides an auxiliary tooling for a multi-station CNC machining center for processing plumbing fittings, which has the following beneficial effects:

[0014] 1. The smoke extraction and dust filtration mechanism is used to collect smoke and dust near the cutter head.

A smoke extraction and dust filtration mechanism 7 and a chip separation and slag removal mechanism 8 are arranged on the lower side of the base 1, and the chip separation and slag removal mechanism 8 is arranged on the upper side of the smoke extraction and dust filtration mechanism 7.

[0027] This mechanism is used to collect and separate small particles of debris from processing waste. It solves the problem that traditional devices cannot clean in real time. The smoke extraction and dust filtration mechanism 7 includes a filter cover 701, which is fixedly connected to the lower surface of the base 1. Multiple suction pipe seats 702 are fixedly connected to the inner side of the processing table 2. Multiple flow channels 703 are opened inside the processing table 2. The two ends of the multiple flow channels 703 are respectively connected to the suction pipe seats 702 and the interior of the filter cover 701. A support cover 704 is threadedly connected to the lower side of the filter cover 701. Multiple exhaust ducts 705 are connected to the lower side of the support cover 704. A housing 706 is fixedly connected to the lower surface of the support cover 704. An induced draft motor 707 is fixedly connected inside the housing 706. A fan blade 708 is fixedly connected to the output end of the induced draft motor 707. A filter element 709 is fixedly connected inside the support cover 704. The fan blade 708 is located under the filter element 709.

[0028] Furthermore, a shock-absorbing pad-like structure is fixedly connected between the filter cover 701 and the base 1.

[0029] Furthermore, a threaded groove is provided between the filter cover 701 and the support cover 704 to make mutual cooperation.

[0030] Furthermore, the diversion channel 703 and the spray pipe 4 are alternately arranged on both sides of the knife platform 3.

[0031] Example 2:

[0032] This mechanism is used to collect and discharge debris generated during processing. Working in conjunction with the fume extraction and dust filtration mechanism 7, it achieves integrated separation of various impurities, improving the cleaning effect of the device. Please refer to [link / reference]. Figure 1-5Furthermore, in conjunction with Embodiment 1, the chip-shaving and slag-discharging mechanism 8 includes a conical metal filter plate 801 and a vibration motor 807. The conical metal filter plate 801 is fixedly connected to the lower surface of the base 1 and is fixedly connected to the inner wall of the support 704. A discharge cylinder 802 is fixedly connected to the lower surface of the conical metal filter plate 801 and is fixedly connected to the inside of the filter 701. A support sleeve 803 is fixedly connected to one side of the discharge cylinder 802. A slag discharge groove 804 is opened inside the discharge cylinder 802. The lower opening of the conical metal filter plate 801 communicates with the inside of the slag discharge groove 804. A motor 805 is fixedly connected inside the support sleeve 803. A worm gear 806 is fixedly connected to the output end of the motor 805. The vibration motor 807 is fixedly connected to the lower surface of the support 704.

[0033] Furthermore, the upper space of the conical metal filter plate 801 is connected to multiple drainage channels 703.

[0034] Furthermore, the discharge cylinder 802 is designed with a square structure.

[0035] In actual operation, when this device is used, during machining in the machining center, the tool holder 3 controls the tool to perform various machining operations on the workpiece. During this period, relatively concentrated debris and locally generated smoke are produced near the fixture table 6. The output of the induced draft motor 707 drives the fan blades 708 to rotate. The output of the fan blades 708 generates negative pressure, which is applied to the vicinity of each tool machining position through the conical metal filter plate 801 and multiple drainage grooves 703. The negative pressure airflow carries the debris into the filter cover 701, and large particles of debris are filtered out. The conical metal filter plate 801 acts as a barrier, allowing small particles and debris to pass through. After passing through the conical metal filter plate 801, these particles are filtered by the filter element 709 and discharged through the exhaust duct 705. When the vibration motor 807 outputs its power, it causes the conical metal filter plate 801 to vibrate. Combined with the structure of the conical metal filter plate 801 and the direction of airflow, this causes debris to fall into the discharge cylinder 802. The output of the motor 805 drives the worm gear 806 to rotate, which pushes the debris that has entered the slag discharge trough 804 out of the discharge cylinder 802, facilitating the separation of debris.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
