Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, and in particular to an external automatic slag removal and filtration device. Background Technology

[0002] We manufacture aerospace shafts and other long shaft parts, characterized by precision turning of the outer diameter and precision boring of deep holes. The outer diameter of these parts is typically machined using a double-end clamping method for both turning and boring. Due to the large length-to-diameter ratio and large hole diameter of these parts, the machining time is long. The outer diameter is machined using tools suitable for the material. The large hole diameter is typically achieved using a hollow tool holder with good rigidity, and axial feed is performed by changing the tool head to ensure accuracy. However, since these parts are generally 3-6 meters long, with long distances for both the outer diameter and the inner hole, this method requires frequent shutdowns to clean the machining head from the cutting disc or the boring chips inside the hole. Because these types of holes are typically 3-6 meters deep, machining both the outer and inner diameters involves long processing times. As processing time accumulates, it's necessary to continuously remove the accumulated chipping material from the machine tool's main chip tray (25) or the machine tool's front tool post (8) from the workpiece mounting tailstock (19) to clear the chip buildup inside the shaft hole. This serves several purposes: firstly, timely cleaning prevents surface scratches; secondly, it promotes heat dissipation and extends tool life; and thirdly, it ensures safety. All of these processes require manual cleaning after machine downtime, resulting in high labor intensity and significant time commitment. Utility Model Content

[0023] Multiple connecting blocks are arranged in a circular array with the central axis of boring bar 3 as the center.

[0024] The working principle of this utility model's external automatic slag removal and filtration device is as follows: To machine the outer diameter, the tool holder 19 and stabilizer 20 are replaced with the tool holder 19, which is installed opposite the fixed chuck 7. After the workpiece is clamped in the fixed chuck 7, the outer diameter is machined using an external turning tool. The iron chips from the outer diameter turning fall into the slag guide plate 15 through the gap of the chip collection disc. When the detector installed in the vibrator 17 detects that the iron chips have accumulated to a certain mass, the vibrator 17 is started. The lifting component 16 drives the second end of the slag guide plate 15 to move up and down. The vibrator 17 causes the slag guide plate 15 to vibrate, thereby removing the iron chips from the slag guide plate 15 onto the filter slag removal conveyor 10. Then, the reduction motor 11 starts and drives the filter slag removal conveyor 10 to send the iron chips to the chip storage box.

[0025] When boring the inner hole, first install the workpiece on the fixed chuck 7. The boring bar 3 is mounted on the tool holder 19, the stabilizer 20, and the linear motion component 18. After adjustment, a suitable boring tool 1 is selected and fixedly mounted on the first end of the boring bar 3. The high-pressure coolant and / or high-pressure air interface is connected to the high-pressure liquid source and / or high-pressure air source through the connecting pipe. The feed parameters are adjusted, and the high-pressure coolant and air are sent to the cutting edge of the boring tool 1 to cool it. At the same time, the linear motion component 18 drives the boring bar 3, the tool holder 19, and the stabilizer 20 to feed along the guide rail assembly to perform boring operations according to the set instructions. The rotating component drives the workpiece to rotate. The boring chips enter the slag collection port 2 next to the cutting edge of the boring tool 1 under the flushing of high-pressure liquid and air, and then flow backward along the hollow structure in the center of the boring bar 3. After reaching the chip discharge pipe 6 connected to the boring bar 3, they are discharged onto the filter chip removal conveyor belt, realizing automatic chip removal without stopping the machine.

[0026] Because the boring bar 3 has a large inner diameter and the high-pressure gas-liquid pipe reaches the front of the boring tool 1 from inside the boring bar 3, directly cooling the cutting edge of the boring tool 1, the return gas-liquid enters the boring bar 3 through the slag collection port 2 at the front of the boring tool 1. The vibrator 17 and the reduction motor 11 both work intermittently. When the vibrator 17 and the filter chip removal conveyor sense that the iron chips have accumulated to the predetermined weight, the vibrator 17 or the reduction motor 11 is started to remove the iron chips; thus completely eliminating the need for manual slag removal operations.

[0027] The technical solution of this utility model is not limited to the specific embodiments described above. All technical modifications made based on the technical solution of this utility model shall fall within the protection scope of this utility model.
