Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, specifically a chip removal structure for a machining center. Background Technology

[0002] During machining, machining centers generate a large amount of high-temperature metal chips. To prevent these chips from accumulating and affecting the normal operation of the equipment, it is necessary to remove them promptly during machining. Existing machining center chip removal structures include spiral blades and chain conveyor belts. The rotating spiral blades push the chips onto the conveyor belt, which then transports them away. Because chain conveyor belts are heat-resistant, they can effectively transfer chips. However, due to the large gaps at the bends of the chain conveyor belt, chips can easily get stuck inside. If not cleaned promptly, this can lead to a large accumulation of chips inside the conveyor belt, increasing friction between the belt components. Furthermore, because the chips are located inside the conveyor belt, cleaning them is difficult and fails to meet operational requirements. Utility Model Content

[0003] The purpose of this invention is to provide a chip removal structure for machining centers, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: the chip removal structure of the machining center includes: The mounting slot is located in a recovery tank for collecting coolant within the machining center. A channel is left between the lower surface of the mounting slot and the inner bottom surface of the recovery tank. The mounting slot and the recovery tank form a water storage tank with only an opening at the top. The conveying unit includes a horizontal conveying section and a climbing conveying section, wherein the entire horizontal conveying section and part of the climbing conveying section are located inside a water storage tank, and the upper end of the climbing conveying section is located outside the processing center. A cleaning section is provided on the climbing conveyor section of the conveyor section, and the cleaning section is used to remove debris that has not fallen off the conveyor section.

[0005] Preferably, the conveying unit includes two baffles, both located within the mounting groove. The baffles have side openings and horizontal and inclined sections. Rotating shafts are provided at both ends of the baffles and at the junction of the horizontal and inclined sections. The two ends of each rotating shaft are rotatably connected to the baffle. Conveying wheels are mounted on the rotating shafts at both ends, and a smooth wheel is mounted on the rotating shaft in the middle. The unit also includes a ring-shaped belt sleeved between the two conveying wheels. The side of the belt is located inside a side shell, and filter holes are evenly distributed on its surface. A cover is provided on the side of the mounting groove, with an opening at the lower end. A motor is located on the outer side of the cover, and the output end of the motor is fixedly connected to one end of one of the rotating shafts.

[0006] Preferably, a guide plate is provided between the two baffles and below the belt, with the lower end of the guide plate inclined toward the lower opening of the cover, and the upper end of the guide plate maintaining a distance from the surface of the belt.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-6 As shown, a chip removal structure for a machining center includes: Mounting slot 2 is located in the recovery tank 3 for collecting coolant in the machining center. A channel is left between the lower surface of mounting slot 2 and the inner bottom surface of recovery tank 3. Mounting slot 2 and recovery tank 3 form a water storage tank with only the upper end open. The conveying section includes a horizontal conveying section and a climbing conveying section. The entire horizontal conveying section and part of the climbing conveying section are located inside the water storage tank, and the upper end of the climbing conveying section is located outside the machining center. The cleaning section is located on the climbing conveyor section of the conveyor section. The cleaning section is used to remove debris that has not fallen off the conveyor section.

[0019] The machining center also includes a bed 1, with an inclined groove at the lower end of the bed 1. The inclined groove is used to allow the debris and coolant generated during machining to collect at the bottom of the bed 1 and enter the recovery tank 3.

[0020] Furthermore, the conveying unit includes two baffles 4, both of which are located within the mounting groove 2. The sides of the baffles 4 are open, and each baffle 4 has a horizontal section and an inclined section. A rotating shaft 5 is provided at both ends of the baffle 4 and at the junction of the horizontal and inclined sections of the baffle 4. The two ends of the rotating shaft 5 are rotatably connected to the baffles 4. A conveying wheel is provided on the rotating shaft 5 at both ends, and a smooth wheel is provided on the rotating shaft 5 in the middle. The unit also includes a ring-shaped belt 6 sleeved between the two conveying wheels. The side of the belt 6 is located inside the side shell, and filter holes are evenly distributed on the surface of the belt 6. A cover 7 is provided on the side of the mounting groove 2. The lower end of the cover 7 is open, and a motor 8 is provided on the outer side of the cover 7. The output end of the motor 8 is fixedly connected to one end of one of the rotating shafts 5.

[0021] The baffle 4 is used to restrict the belt 6, allowing the belt 6 to move according to the shape of the baffle 4. The water storage tank formed by the mounting groove 2 and the recycling pool 3 can be used to store coolant. When the coolant fills the water storage tank, the upper surface of the horizontal conveying section of the belt 6 is submerged in the coolant in the water storage tank. At this time, the distance between the liquid level of the coolant and the upper surface of the belt 6 is about 3mm. When debris is generated, the debris will fall above the belt 6. Since the belt 6 is immersed in the coolant, the debris will exchange heat with the coolant, thereby rapidly reducing the temperature of the debris and preventing the debris from burning the belt 6.

[0022] As coolant continuously enters the storage tank, excess coolant overflows from the storage tank into the recovery tank 3. The bottom of the recovery tank 3 is equipped with a drain pipe, which is connected to an external suction device to promptly remove the coolant from the recovery tank 3.

[0023] The surface of the conveyor wheel is provided with toothed grooves, and the inner surface of the belt 6 is also provided with toothed grooves. Therefore, when the motor 8 drives the rotating shaft 5 to rotate, the belt 6 will move through the cooperation of the belt 6 and the toothed grooves on the conveyor wheel. The smooth wheel is used to support the belt 6.

[0024] The diameter of the filter hole is about 2mm. Since the workpiece produces flakes or blocks during processing, the length of its long side is generally greater than 2mm. Therefore, the debris will hardly get stuck in the filter hole. The machining center at this location does not include the function of a grinding machine, so the grinding debris will not clog the filter hole.

[0025] A recycling bin needs to be placed at the lower opening of the casing 7. During the use of the chip removal mechanism, the motor 8 drives the belt 6 to rotate, continuously transporting the debris that falls onto the belt 6 to the casing 7, where it falls into the recycling bin under the action of gravity. If too much debris is collected in the recycling bin, it is only necessary to replace the recycling bin.

[0026] Motor 8 is controlled by a PLC controller, which can adjust parameters such as the speed of motor 8.

[0027] Furthermore, a guide plate 9 is provided between the two baffles 4 and below the belt 6. The lower end of the guide plate 9 is inclined toward the lower opening of the cover 7, and the upper end of the guide plate 9 is kept at a distance from the surface of the belt 6.

[0028] The distance between the guide plate 9 and the belt 6 is about 1mm. For some lighter debris that can adhere to the belt 6 through the coolant, the guide plate 9 can clean out this part of the debris and guide it into the cover 7. Under the action of gravity, it falls into the recycling bin. Since the upper end of the guide plate 9 does not contact the belt 6, it can prevent some smaller debris from getting stuck in the water filter holes on the belt 6.

[0029] Furthermore, the cleaning unit includes a rotatable cleaning brush 10 disposed inside the housing 7. The bristles of the cleaning brush 10 can contact the lower surface of the belt 6. The cleaning brush 10 is located below the guide plate 9. An intermediate shaft 11 is disposed on the side of the housing 7. Gears 12 are disposed on the rotating shaft 5, the intermediate shaft 11, and the cleaning brush 10. The gears 12 on the rotating shaft 5 and the intermediate shaft 11 mesh with each other, and the intermediate shaft 11 meshes with the gears 12 on the cleaning brush 10.

[0030] The cleaning brush 10 is a plastic brush. When the rotating shaft 5 rotates, it can drive the cleaning brush 10 to rotate through the transmission of three gears 12. The rotation direction of the cleaning brush 10 is the same as that of the rotating shaft 5, so that the cleaning brush 10 can clean the lower surface of the belt 6. By controlling the transmission ratio of the three gears 12, the rotation speed of the cleaning brush 10 is greater than the rotation speed of the rotating shaft 5. The rotation speed of the cleaning brush 10 is about 3 times the rotation speed of the rotating shaft 5, so as to efficiently and stably clean the debris off the belt 6.

[0031] Furthermore, the outer side of the casing 7 is provided with a cover plate 13 for covering the three gears 12.

[0032] The cover plate 13 is used to cover the gear 12, and the gear 12 needs to be lubricated with grease. The cover plate 13 can prevent excessive loss of grease.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
