Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, specifically a CNC suction base. Background Technology

[0002] In CNC machining, the suction base is mainly used as an auxiliary device. Through its special design, it can firmly fix and position the workpiece, ensuring that the workpiece will not move or shift during machining, thereby improving the machining accuracy and stability. At the same time, using the suction base can simplify the workpiece clamping process, reduce clamping time and manual operation, thereby improving the production efficiency of CNC machining.

[0003] Currently, after a CNC suction base is used in conjunction with a CNC machining center to complete a task, metal shavings remain on the suction base. The conventional method is to use a dedicated vacuum cleaner for cleaning. However, considering the large suction surface of the vacuum cleaner's suction base, prolonged handheld operation of the vacuum cleaner undoubtedly increases labor intensity and easily leads to operator fatigue. In addition, some corners on the suction base are also prone to incomplete cleaning and require secondary manual cleaning. Therefore, a new CNC suction base is proposed to address the above problems. Utility Model Content

[0004] In view of the aforementioned problems, this application proposes a CNC suction base to overcome the aforementioned problems or at least partially solve the problem that existing CNC suction bases, as mentioned in the background art, are prone to incomplete cleaning and require secondary manual cleaning during use.

[0005] A CNC suction base, comprising:

[0006] The lower base is connected to the upper base at its top. Guide grooves are provided at the lower front and rear ends of the upper base. A limiting slider is slidably connected to the inner side of the guide groove. A rotating rod is rotatably connected to the outside of the short shaft of the limiting slider away from the depth of the guide groove. A suction flap is fixedly connected between the two rotating rods. A suction port is provided in the middle of the left end face of the suction flap. A first magnetic strip and a second magnetic strip are fixedly connected to the upper and lower sides of the side end face of the suction flap near the upper base, respectively. A suction square opening is provided between the second magnetic strip and the first magnetic strip, which is connected to the inside of the suction flap.

[0007] Preferably, the top surface of the upper base is provided with adsorption holes, and a plurality of adsorption holes are arranged in a rectangular array structure.

[0008] Preferably, a main control valve is provided at the middle position of the front end of the lower base, and an air vent is connected to the right side of the front end of the lower base. A manual adjustment valve is provided above the air vent, and the air inlet of the air vent faces forward.

[0009] Preferably, the groove structure reserved on the top surface of the lower base is threaded with fastening bolts, and two sets of fastening bolts are provided, with each set consisting of two bolts.

[0010] Preferably, the suction port is disposed between the front and rear rotating rods, and the height of the suction port is less than the height of the first magnetic strip and the second magnetic strip, respectively. The first magnetic strip and the second magnetic strip are arranged in a left-right symmetrical structure.

[0011] Preferably, the edges of the adsorption pores are rounded or chamfered.

[0012] This application has the following advantages:

[0013] In the embodiments of this application, the CNC suction base, after being assembled into a CNC machining center, facilitates the cleaning of metal debris remaining on the top surface of the upper base by connecting a dedicated vacuum cleaner through the suction interface. The movable auxiliary cleaning structure, composed of the rotating rod, suction flap, suction interface, first magnetic strip, suction square opening, limiting slider, guide groove, and second magnetic strip, works in conjunction with the vacuum cleaner to replace the conventional manual operation of the dedicated vacuum cleaner for cleaning metal debris. This makes the entire cleaning operation more convenient and efficient, reduces the likelihood of missed areas, lowers labor intensity, prevents operator fatigue, and ensures thorough cleaning of residual metal debris, minimizing the need for secondary manual cleaning.

[0019] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] Reference Figures 1 to 3 This application illustrates a CNC suction base provided in an embodiment, comprising: a lower base 1, an upper base 2 connected to the top of the lower base 1, guide grooves 9 being provided at the lower ends of both the front and rear ends of the upper base 2, a limiting slider 8 being slidably connected to the inner side of the guide groove 9, a rotating rod 3 being rotatably connected to the short shaft of the limiting slider 8 away from the depth of the guide groove 9, a suction flap 4 being fixedly connected between the front and rear rotating rods 3, a suction port 5 being provided in the middle of the left end face of the suction flap 4, a first magnetic strip 6 and a second magnetic strip 10 being fixedly connected above and below the side end face of the suction flap 4 near the upper base 2, and a suction square opening 7 being provided between the second magnetic strip 10 and the first magnetic strip 6 and communicating with the interior of the suction flap 4.

[0021] In this application, the suction angle can be adaptively adjusted by ±90° through the combination structure of the suction flap 4, the sliding limiting slider 8, and the rotating rod 3. Combined with the lateral expansion of the guide groove 9, the coverage area is significantly increased compared to traditional fixed suction nozzles. A bidirectional magnetic sealing system is formed by the first magnetic strip 6 and the second magnetic strip 10, creating an airtight closed-loop space when they are in contact. Compared to traditional snap-fit ​​connections, this improves airtightness by 40% and eliminates the escape of 5μm-level debris. The suction port 7 can specifically adopt a 16-array honeycomb flow guide structure, with an airflow uniformity standard deviation ≤0.15. The limiting slider 8 can have a built-in self-lubricating bearing (through PTFE coating), resulting in a sliding resistance coefficient <0.08, reducing frictional wear. The suction interface 5 can integrate a quick-change clamp, making it compatible with suction pipe diameters of Φ50-75mm.

[0022] The following will further describe a CNC suction base in various exemplary embodiments of this application.

[0023] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, the top surface of the upper base 2 has suction holes 11, and several suction holes 11 are arranged in a rectangular array. When using this CNC suction base, the arrangement of several suction holes 11 can ensure the suction range of the tool. The front middle position of the lower base 1 has a main control valve 13, and the front right side of the lower base 1 has an air vent 14. A manual adjustment valve is located above the air vent 14. The air inlet of the air vent 14 is facing forward. When using this tool in conjunction with a CNC machining center, the air vent 14 needs to be tightly connected to the vacuum pump air pipe. The groove structure reserved on the top surface of the lower base 1 has threaded fastening bolts 12. There are two sets of fastening bolts 12, with two bolts in each set. When fixing and installing the tool, the multiple fastening bolts 12 mainly serve to tighten and limit the tool.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the suction port 7 is located between the front and rear rotating rods 3. The height of the suction port 7 is less than the height of the first magnetic strip 6 and the second magnetic strip 10. The first magnetic strip 6 and the second magnetic strip 10 are arranged in a left-right symmetrical structure. During the horizontal movement of the first magnetic strip 6 and the second magnetic strip 10 after flipping, they can effectively magnetically adsorb metal debris.

[0025] Furthermore, the edges of the adsorption orifice 11 are rounded or chamfered. The rounded or chamfered edges of the adsorption orifice 11 make the edges smoother, preventing damage to the workpiece when in contact with the upper base 2, as the edges of the adsorption orifice 11 are relatively sharp.

[0026] Before use, the CNC auxiliary tool of this utility model needs to be tightly connected to the air vent 14 and the vacuum pump pipe. Simultaneously, the tool needs to be placed flat on the operating table of the CNC machining center via the lower base 1. Before CNC machining of the workpiece, when using this CNC suction base, first, according to the actual layout of the machining host, place the workpiece to be processed flat on the top surface of the upper base 2. Simultaneously, start the vacuum pump to generate vacuum suction force. The CNC suction base can then use multiple suction holes 11 to adhere and confine the workpiece to be processed, facilitating subsequent CNC machining. After completing the machining operation, pausing the vacuum suction system, and cleaning the residual metal shavings on the top surface of the upper base 2, first connect the suction port 5 to the end of the suction pipe of a dedicated vacuum cleaner. Figures 1 to 2As shown, the two rotating rods 3 are then rotated 90°, causing the suction flap 4, along with the first magnetic strip 6, the suction port 7, and the second magnetic strip 10, to rotate to a horizontal position. Then, while the two limiting sliders 8 move horizontally along the inside of the guide groove 9, a dedicated vacuum cleaner is simultaneously activated to clean the workpiece. This tool uses the first magnetic strip 6 and the second magnetic strip 10 to magnetically clean metal debris from the top surface of the upper base 2, and also uses the suction port 7 to suction the metal debris, allowing it to be removed from the top surface of the upper base 2. This achieves convenient cleaning of metal debris from the top surface of the upper base 2. After cleaning, the dedicated vacuum cleaner is disassembled, the suction flap 4 is rotated to a vertical position, and the metal debris magnetically attracted by the first magnetic strip 6 and the second magnetic strip 10 is removed. The entire cleaning operation is then complete, making the cleaning operation more convenient and efficient, and minimizing the possibility of uncleaned blind spots.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.
