Technical Field

[0001] This utility model relates to the field of chip removal technology for machining centers, and specifically to a chip removal device for CNC machining centers. Background Technology

[0002] During the metal cutting process in CNC machining centers, a large amount of metal chips and waste coolant are generated. As a key auxiliary component, the performance of the chip removal device directly affects the processing efficiency, equipment life and resource recycling rate.

[0003] Currently, traditional chip removal devices mostly use fixed-installation filter plates. Over long-term use, debris easily accumulates on the filter plate surface, and fine debris can clog the filter plate pores, leading to incomplete solid-liquid separation. This not only affects the smoothness of chip removal but also requires frequent machine shutdowns for filter plate cleaning, increasing maintenance costs and labor time. To solve these problems, this utility model provides a chip removal device for CNC machining centers. Utility Model Content

[0004] To address the aforementioned technical deficiencies, the purpose of this utility model is to provide a chip removal device for CNC machining centers. The filter plate of this device is installed in a floating manner and can vibrate continuously with the movement of the auger, reducing the accumulation and residue of debris on the filter plate. At the same time, the vibration makes it easier for the coolant in the pores of the filter plate to flow down. In conjunction with the brush bristles on the auger, the inside of the filter holes on the filter plate can be cleaned.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a chip removal device for a CNC machining center, comprising: The machine tool base has an upper surface that is sloping with one side higher than the other, and a collection groove is provided at the lowest point of the sloping surface. A filter plate, which is installed at the opening of the collection tank; Screwdriver, which is installed above the filter plate; The auger is driven by a motor installed on one side of the machine tool base, and the end of the auger away from the motor and located on the side wall of the machine tool base has a discharge port.

[0006] Preferably, the filter plate is floatingly installed inside the collection tank and vibrates up and down with the movement of the auger.

[0007] Preferably, the filter plate is slidably installed inside the collection tank along the height direction of the collection tank, and a first spring is connected between the lower two ends of the filter plate and the bottom side wall of the collection tank. The first spring has a pressing force to press the filter plate upward.

[0008] Preferably, a plurality of telescopic rods are fixedly installed on the central shaft of the auger, the telescopic rods comprising: A fixed frame is fixedly installed on the central shaft of the auger. The inner rod is slidably installed inside the fixed frame, and a second spring is connected between the inner rod and the inner side wall of the fixed frame; The inner rod has an arc-shaped end located outside the fixed frame, and the spring force of the second spring is greater than that of the first spring.

[0009] Preferably, multiple bristles are fixedly connected to the outer ring surface of the spiral plate of the auger.

[0010] Preferably, limiting blocks for limiting the height of the filter plate are fixedly connected to the walls on both sides of the collection tank.

[0011] Preferably, an extension plate is fixedly connected to the outer wall of the machine tool base, below the outlet, and the auger extends from the outlet to the top of the extension plate.

[0012] Preferably, the extension plate is a concave arc plate.

[0013] Preferably, the bottom sidewall of the collection tank is an inclined surface with one end higher than the other, and the lower end of the collection tank wall penetrates the machine tool base.

[0014] Preferably, the height of the end of the collection tank furthest from the outlet is lower than the height of the end closest to the outlet.

[0015] The beneficial effects of this utility model are as follows: This invention, through the arrangement of a filter plate, a first spring, a telescopic rod, and brush bristles, enables the filter plate to vibrate continuously with the auger movement, effectively reducing the accumulation and residue of debris on the filter plate. At the same time, the vibration facilitates the flow of coolant in the filter plate pores, and the brush bristles can clean the inside of the filter holes on the filter plate during the vibration process, solving the problems of easy clogging and debris residue in the fixed filter plate in the prior art.

[0016] This invention sets the upper side of the machine tool base as an inclined surface, which can guide the debris and coolant to converge into the collection tank. The bottom of the collection tank is also set as an inclined surface to form a double guiding structure, which can make the coolant flow quickly to the outlet, greatly improving the coolant recovery efficiency. In addition, the flow direction of the coolant is different from the discharge direction of the debris, which is more conducive to subsequent recycling work. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a chip removal device for CNC machining centers, such as... Figures 1 to 6 As shown.

[0027] Example 1: A chip removal device for a CNC machining center includes a machine tool base 1. The upper side of the machine tool base 1 is an inclined plane with one side higher than the other. A collection groove 2 is provided at the lowest point of the inclined plane. A filter plate 3 is installed at the opening of the collection groove 2. An auger 4 is installed above the filter plate 3. One end of the central shaft of the auger 4 is connected to a motor 9 fixed to the side wall of the machine tool base 1. When the CNC machining center generates chips and coolant, the inclined plane of the machine tool base 1 guides the mixture to flow into the collection groove 2. The coolant seeps into the collection groove 2 through the filter plate 3, while the chips are intercepted above the filter plate 3.

[0028] Motor 9 drives auger 4 to rotate. The spiral plate of auger 4 pushes the debris on filter plate 3 to the end away from motor 9, and finally discharges it through the outlet on the side wall of machine tool base 1. At the same time, an extension plate 10 is fixed on the outer side wall of machine tool base 1 and below the outlet. The end of auger 4 extends above the extension plate 10. The discharged debris falls on the extension plate 10 and slides to the designated collection area. The extension plate 10 is concave arc-shaped, which can prevent debris from falling to the ground and causing pollution.

[0029] The bottom sidewall of the collection tank 2 is designed as a slope with one end higher than the other, and the height of the end of the collection tank 2 away from the outlet is lower than the height of the end closer to the outlet. The tank wall at the end with the lower bottom height penetrates through the machine tool base 1. When the coolant enters the collection tank 2, it will flow towards the end away from the outlet under the guidance of the slope of the bottom and be discharged through the penetrating end, achieving separate recovery of the coolant. The coolant and debris are discharged in opposite directions to avoid re-mixing during the recovery process and improve the efficiency of classified recovery.

[0030] Example 2: This embodiment mainly introduces the installation method of filter plate 3. Filter plate 3 is slidably installed inside collection tank 2, and filter plate 3 slides inside collection tank 2 along the height direction of collection tank 2. The two ends of the lower side of filter plate 3 are respectively connected to the bottom side wall of collection tank 2. The first spring 5 always applies an upward pressing force to filter plate 3.

[0031] Limiting blocks 7 are symmetrically fixed on the walls of the collection tank 2 on both sides. The limiting blocks 7 are located above the filter plate 3 and are used to limit the maximum height of the filter plate 3's upward vibration to avoid excessive collision between the filter plate 3 and the auger 4.

[0032] Multiple telescopic rods are fixed at intervals on the central axis of the auger 4. Each telescopic rod consists of a fixed frame 11, an inner rod 12, and a second spring 6. The fixed frame 11 is fixed to the central axis of the auger 4. The inner rod 12 slides through the fixed frame 11. The second spring 6 is connected between the inner rod 12 and the inner wall of the fixed frame 11. The elastic force of the second spring 6 is greater than that of the first spring 5. The end of the inner rod 12 that extends out of the fixed frame 11 is designed as an arc surface.

[0033] When the auger 4 rotates under the drive of the motor 9, the telescopic rod rotates synchronously with the auger 4. The arc end of the inner rod 12 will periodically contact the upper surface of the filter plate 3. Since the second spring 6 has a greater elastic force, the inner rod 12 will press the filter plate 3 to move downward and compress the first spring 5. When the inner rod 12 rotates away from the filter plate 3 with the auger 4, the elastic force of the first spring 5 pushes the filter plate 3 to return to its original position. This cycle realizes the up and down vibration of the filter plate 3, which can reduce the accumulation of debris on the filter plate and affect the cleaning work of the auger 4. At the same time, the vibration makes it easier for the coolant in the filter plate pores to flow down.

[0034] Example 3: Based on Embodiment 2, multiple bristles 8 are fixedly arranged on the outer ring surface of the spiral plate of the auger 4. The bristles 8 rotate with the auger 4. During the vibration of the filter plate 3, the bristles 8 will insert into the filter holes of the filter plate 3 to clean out the small debris stuck in the filter holes, further preventing the filter plate 3 from clogging.

[0035] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
