Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to a chip collection device for CNC machine tools. Background Technology

[0002] Numerical control machine tools are a type of automated machine tool equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, input them to the numerical control device through an information carrier, and after calculation and processing, the numerical control device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and size required by the drawings. The chip collection device for CNC machine tools is an important piece of equipment used to collect and remove metal chips generated during the machining process of CNC machine tools. According to their different collection methods, they are also divided into chain plate chip collection devices, scraper chip collection devices, magnetic chip collection devices, spiral chip collection devices, chip removal devices, etc.

[0003] However, when using the spiral chip collection device, the chip collection trolley needs to be pushed below the discharge port of the spiral chip collection device to collect the chips. However, during the process of discharging the chips into the chip collection trolley, factors such as wind and vibration may cause the chips to fall directly to the ground. This type of chip collection device has low accuracy and therefore does not meet the current requirements. In response, we propose a chip collection device for CNC machine tools. Utility Model Content

[0004] The purpose of this utility model is to provide a chip collection device for CNC machine tools, in order to solve the problems mentioned in the background art, such as the need to push the chip collection trolley to the bottom of the discharge port of the spiral chip collection device to collect the chips, but the possibility of the chips falling directly to the ground due to wind, vibration and other factors during the process of discharging the chips into the chip collection trolley, and the low accuracy of such chip collection devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chip collection device for CNC machine tools, comprising a spiral chip conveyor, a discharge port installed on one side of the outer surface of the spiral chip conveyor, a square metal shell fixed to the outer surface of the discharge port, a stepper motor fixedly installed on one side inside the square metal shell, the output shaft of the stepper motor being connected to a transmission shaft via a coupling, a first gear fixedly sleeved on the lower side of the outer surface of the transmission shaft, the first gear meshing with a second gear, a roller bearing ring connected to the square metal shell via a roller bearing at the shaft center of the second gear, and a sealed connection port communicating with the interior of the discharge port located below the roller bearing ring; Both sides of the lower end face of the roller bearing ring are fixedly connected to a synchronous rotating shaft. The synchronous rotating shaft is movably inserted into the interior of the sealing connection port. The outer side of the two synchronous rotating shafts is provided with an external threaded sleeve fixedly sleeved on the outer surface of the sealing connection port, and the external threaded sleeve is connected to the square metal shell through a threaded structure. The four corners of the outer surface of the bottom end of the sealing connection are all first inclined surfaces. A debris collection trolley is provided below the four first inclined surfaces. The upper end of the debris collection trolley is provided with a positioning connection port, and the shape of the inner wall of the positioning connection port corresponds to the shape of the outer surface of the bottom end of the sealing connection.

[0006] Preferably, the inner wall diameter of the sealing connection is the same as the inner wall diameter of the discharge port, and the sealing connection and the discharge port are on the same vertical horizontal line.

[0007] Preferably, a filled sealing sleeve is fixedly installed on the upper side of the inner wall of the sealing connection port. The upper half of the filled sealing sleeve is located inside the discharge port. The outer surface of the filled sealing sleeve located inside the discharge port is in contact with the inner wall of the discharge port, and both the upper and lower end faces of the filled sealing sleeve are second inclined surfaces.

[0008] Preferably, an anti-detachment ring is fixedly sleeved on the outer surface of the synchronous rotating shaft inserted into the sealed connection port. The outer side of the anti-detachment ring is provided with a release groove located inside the sealed connection port. The outer surface of the anti-detachment ring is in contact with the inner wall of the release groove, and the anti-detachment ring and the release groove are slidably connected.

[0009] Preferably, a universal pulley is fixedly installed at each of the four corners of the lower end face of the spiral chip conveyor and the chip collection trolley, and a manual push rod is fixedly installed at the rear end face of the chip collection trolley.

[0011] Preferably, the stepper motor is provided with an arc-shaped cover plate located on the outer surface of the square metal casing, and the square metal casing and the arc-shaped cover plate are fixed together by screws.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model allows for the following process: when the equipment is needed, the debris collection trolley is pushed to the bottom of the square metal casing. Then, a stepper motor pushes the sealing connection port located on the lower end of the square metal casing into the positioning connection port located on the upper end of the debris collection trolley. The debris collected by the spiral debris discharge device can then be discharged into the debris collection trolley in a sealed environment. This technical solution prevents debris from falling to the ground due to wind or vibration during the process of discharging debris into the debris collection trolley, thereby improving the accuracy of this debris collection device. 2. This utility model uses a stepper motor to drive the threaded structure between the external threaded sleeve and the square metal shell to move the sealing connection downwards, thereby completing the connection between the sealing connection and the debris collection trolley. This threaded structure prevents the sealing connection from moving upwards on its own. The above technical solution can prevent the gap between the sealing connection and the positioning connection from forming due to the vibration of the equipment during long-term debris discharge. This would prevent the debris collection trolley from being misaligned with the spiral chip conveyor and constantly colliding with the bottom end of the sealing connection due to the vibration of the spiral chip conveyor, thus causing damage to it.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] The spiral chip conveyor 1 (model XDPL) mentioned in this utility model, the first gear 9 (model M06) and the stepper motor 7 (model DM542) can be obtained from the market or through private customization.

[0017] Please see Figures 1 to 4 An embodiment of this utility model provides a chip collection device for CNC machine tools, including a spiral chip conveyor 1. A discharge port 16 is installed on one side of the outer surface of the spiral chip conveyor 1. A square metal shell 3 is fixed to the outer surface of the spiral chip conveyor 1 on the outside of the discharge port 16. A stepper motor 7 is fixedly installed on one side inside the square metal shell 3. The output shaft of the stepper motor 7 is connected to a transmission shaft 8 through a coupling. A first gear 9 is fixedly sleeved on the lower side of the outer surface of the transmission shaft 8. The first gear 9 meshes with a second gear 10. The shaft of the second gear 10 is connected to a roller bearing ring 11 that is connected to the square metal shell 3 through a roller bearing. A sealed connection port 4 communicating with the interior of the discharge port 16 is provided below the roller bearing ring 11. A synchronous rotating shaft 18 is fixedly connected to both sides of the lower end face of the roller bearing ring 11. The synchronous rotating shaft 18 is movably inserted into the interior of the sealing connection port 4. An external threaded sleeve 13 is fixedly sleeved on the outer surface of the sealing connection port 4 on the outer side of the two synchronous rotating shafts 18, and the external threaded sleeve 13 is connected to the square metal shell 3 through a threaded structure. The four corners of the outer surface of the bottom end of the sealing connection port 4 are all first inclined surfaces 5. A debris collection cart 2 is provided below the four first inclined surfaces 5. The upper end of the debris collection cart 2 is provided with a positioning connection port 6, and the shape of the inner wall of the positioning connection port 6 corresponds to the shape of the outer surface of the bottom end of the sealing connection port 4.

[0018] The spiral chip conveyor 1 and the chip collection trolley 2 are each fixedly equipped with a universal pulley at each of the four corners of their lower end faces, and a manual push rod is fixedly installed at the rear end face of the chip collection trolley 2. When the equipment is needed, the spiral chip conveyor 1 is pushed by the universal pulleys installed on its lower end face to connect it to the CNC machine tool. Then, the chip collection trolley 2 is pushed to the bottom of the square metal housing 3 by the universal pulleys installed on its lower end face. Then, the stepper motor 7 is started, which drives the transmission shaft 8 connected to it and the first gear 9 fixedly sleeved on the outer surface of the transmission shaft 8 to rotate. The rotating first gear 9 drives the second gear 10 meshing with it and the roller bearing ring 11 connected to the shaft of the second gear 10 to rotate together. When the roller bearing ring 11 rotates, the fixed... Two synchronous rotating shafts 18 fixedly mounted on the lower end face of the roller bearing ring 11 will rotate synchronously. When the two synchronous rotating shafts 18 rotate, the sealing connection port 4 inserted by the two synchronous rotating shafts 18 and the external threaded sleeve 13 fixedly sleeved on the outer surface of the sealing connection port 4 will rotate together. Through the threaded structure between the external threaded sleeve 13 and the square metal shell 3, the rotating sealing connection port 4 can move up and down. At this time, the sealing connection port 4 moves down. As the sealing connection port 4 descends, the bottom end of the sealing connection port 4, whose four corners on the outer surface are all first inclined surfaces 5, will enter the interior of the positioning connection port 6 located on the upper end face of the debris collection trolley 2. Under the push of the first inclined surface 5, the position of the debris collection trolley 2 will be adjusted so that the bottom end of the sealing connection port 4 is tightly fitted with the inner wall of the positioning connection port 6.

[0019] The inner diameter of the sealing connection port 4 is the same as the inner diameter of the discharge port 16, and the sealing connection port 4 and the discharge port 16 are on the same vertical horizontal line; a storage tank is provided on the lower side of the inside of the debris collection trolley 2, and the inside of the positioning connection port 6 is connected to the inside of the storage tank; when the bottom end of the sealing connection port 4 enters the inside of the positioning connection port 6 and can no longer move the sealing connection port 4 downward, the spiral chip removal device 1 is activated to collect the debris, and it will be discharged into the inside of the sealing connection port 4 through the discharge port 16. The debris discharged into the inside of the sealing connection port 4 will fall into the inside of the storage tank under the action of gravity. Through the above technical solution, the debris can be discharged into the storage tank inside the debris collection trolley 2 in a sealed environment, thereby preventing the debris from falling to the ground due to wind or vibration during the process of discharging the debris into the debris collection trolley 2, thereby improving the accuracy of this debris collection device; In the above technical solution, the stepper motor 7, which serves as the driving source, moves the sealing connection port 4 downward by driving the threaded structure between the external threaded sleeve 13 and the square metal shell 3, thereby completing the connection between the sealing connection port 4 and the debris collection trolley 2. Through this threaded structure, it is possible to prevent the sealing connection port 4 from moving upward on its own. The above technical solution can prevent the gap between the sealing connection port 4 and the positioning connection port 6 from being generated due to the vibration of the equipment during long-term debris discharge. This would prevent the debris collection trolley 2 from being misaligned with the spiral chip removal device 1 due to the vibration of the spiral chip removal device 1 during operation, and from continuously colliding with the bottom end of the sealing connection port 4, thereby causing damage.

[0020] A filling sealing sleeve 14 is fixedly installed on the upper side of the inner wall of the sealing connection port 4. The upper half of the filling sealing sleeve 14 is located inside the discharge port 16. The outer surface of the filling sealing sleeve 14 located inside the discharge port 16 is in contact with the inner wall of the discharge port 16, and the upper and lower end faces of the filling sealing sleeve 14 are both second inclined surfaces 15. The filling sealing sleeve 14 can fill the gap between the sealing connection port 4 and the discharge port 16 when the sealing connection port 4 moves downward, thereby preventing debris from getting stuck between the sealing connection port 4 and the discharge port 16.

[0021] An anti-detachment ring 12 is fixedly sleeved on the outer surface of the synchronous rotating shaft 18 inserted into the sealing connection port 4. The outer side of the anti-detachment ring 12 is provided with a release groove 17 located inside the sealing connection port 4. The outer surface of the anti-detachment ring 12 is in contact with the inner wall of the release groove 17, and the anti-detachment ring 12 and the release groove 17 are slidably connected. The anti-detachment ring 12 fixedly sleeved on the outer surface of the synchronous rotating shaft 18 can prevent the external threaded sleeve 13 fixedly sleeved on the outer surface of the sealing connection port 4 from completely detaching from the inside of the square metal shell 3.

[0022] An arc-shaped cover plate is provided in front of the stepper motor 7 on the outer surface of the square metal housing 3, and the square metal housing 3 and the arc-shaped cover plate are fixed together by screws; the arc-shaped cover plate can protect the internal structure of the square metal housing 3, and when the internal structure of the square metal housing 3 fails, the arc-shaped cover plate can be removed to repair the internal structure of the square metal housing 3.
