Abstract
Description
Technical Field
[0001] This utility model relates to the field of machine tool technology, and in particular to a chip removal device for machine tools. Background Technology
[0002] Machining processes (such as turning, milling, and drilling) generate a large amount of metal chips (or non-metallic material fragments). If these chips accumulate on the workpiece, cutting tool, or machining area, they can cause cutting interference, surface scratches, and abnormal tool stress. Metal chips (such as steel, aluminum, and copper) have high recycling value. An efficient chip removal system can collect and transport the chips to a recycling facility.
[0003] Existing chip removal methods for machine tools use spiral chip removal, but spiral chip removal can only transport iron chips that fall into the chip removal groove. Over time, this can cause iron chips that accumulate on both sides of the chip removal groove to be unable to be discharged. Utility Model Content
[0004] The purpose of this invention is to overcome the existing defects and provide a chip removal device for machine tools that can draw falling iron chips into the cleaning groove of the spiral chip removal system, thus preventing the accumulation of iron chips.
[0005] The technical solution to achieve the above objective is as follows: a chip removal device for machine tools, including a chip collection box, a spiral chip removal structure installed at the bottom of the chip collection box, two first support frames mirror-imagely provided on the upper surface of the chip collection box, a corresponding limiting frame inserted into each first support frame, a corresponding second support frame rotatably connected to each limiting frame, an arc-shaped collection groove connected to the lower end of the two second support frames, a plurality of through holes opened at the bottom of the arc-shaped collection groove, a movable groove opened on the side wall of the chip collection box, a first rotating rod connected to the side wall of the arc-shaped collection groove, the first rotating rod being located inside the movable groove, and a rocker drive assembly for driving the arc-shaped collection groove to shake connected to the first rotating rod.
[0006] Preferably, the rocker drive assembly includes a first crank, a second rotating rod, a second crank, and a drive motor. The first rotating rod is rotatably connected to one end of the first crank, and the other end of the first crank is rotatably connected to the second rotating rod. The second rotating rod is connected to one end of the second crank, and the other end of the second crank is connected to the output shaft of the drive motor.
[0007] Preferably, the scrap collection box is equipped with a protective cover, the fixed end of the drive motor is connected to the inner wall of the protective cover, and the rocker drive assembly is located inside the protective cover.
[0008] Preferably, a first bearing is provided at the junction of the first rotating rod and the first crank, and a second bearing is provided at the junction of the first crank and the second rotating rod.
[0009] Preferably, the first support frame and the second support frame are located between the limiting frame, and the first support frame, the second support frame and the limiting frame are in contact with each other.
[0010] Preferably, both the first support frame and the second support frame have circular holes, and the center of each circular hole is on the same straight line as the center of the arc-shaped collection groove. The first support frame is located in the middle part of the side of the scrap collection box, and the second support frame is located in the middle part of the side of the arc-shaped collection groove.
[0011] Preferably, the arc-shaped collecting groove is located above the spiral chip removal structure, and the width of the cleaning groove of the spiral chip removal structure is greater than the width of the multiple through holes.
[0012] The beneficial effects of this utility model are: the second crank is driven to rotate by the drive motor, and the second crank drives the second rotating rod to rotate around the output shaft of the drive motor, thereby causing the first crank to drive the first rotating rod to swing back and forth. Since the first rotating rod is connected to the arc-shaped collecting groove, it can drive the arc-shaped collecting groove to swing back and forth around the central axis of the circular hole of the second support frame, thereby discharging the iron filings in the arc-shaped collecting groove from multiple through holes into the cleaning groove of the spiral chip removal structure, preventing the accumulation of iron filings and facilitating the chip removal of the machine tool. The upper surface of the scrap collection box is mirrored with two first support frames, each with a corresponding limiting frame inserted inside. Each limiting frame is rotatably connected to a corresponding second support frame. The lower ends of the two second support frames are connected to an arc-shaped collection trough. The bottom of the arc-shaped collection trough has multiple through holes. This not only allows the scrap to be discharged into the cleaning trough of the spiral scrap removal structure, but also allows large pieces of waste to be screened out, preventing them from damaging the spiral scrap removal structure.

[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] like Figure 1-4 As shown, a chip removal device for machine tools includes a chip collection box 1. A spiral chip removal structure 2 (the spiral chip removal structure 2 is an existing machine tool spiral chip removal device) is installed at the bottom of the chip collection box 1. Two first support frames 3 are mirror-imagely provided on the upper surface of the chip collection box 1. A corresponding limiting frame 4 is inserted into each first support frame 3. A corresponding second support frame 5 is rotatably connected to each limiting frame 4. An arc-shaped collection groove 6 is connected to the lower end of the two second support frames 5. Multiple through holes 7 are opened at the bottom of the arc-shaped collection groove 6. This not only allows the chips to be discharged into the cleaning groove of the spiral chip removal structure 2, but also allows large pieces of waste to be screened out to prevent them from damaging the spiral chip removal structure 2. A movable groove 8 is opened on the side wall of the chip collection box 1. A first rotating rod 9 is connected to the side wall of the arc-shaped collection groove 6. The first rotating rod 9 is located inside the movable groove 8. A rocker drive assembly for driving the arc-shaped collection groove 6 to shake is connected to the first rotating rod 9.
[0018] Specifically, the rocker drive assembly includes a first crank 10, a second rotating rod 11, a second crank 12, and a drive motor 15. The first rotating rod 11 is rotatably connected to one end of the first crank 10, and the other end of the first crank 10 is rotatably connected to the second rotating rod 11. The second rotating rod 11 is connected to one end of the second crank 12, and the other end of the second crank 12 is connected to the output shaft of the drive motor 15. Specifically, a protective cover 16 is installed on the scrap collection box 1. The fixed end of the drive motor 15 is connected to the inner wall of the protective cover 16. The rocker drive assembly is located inside the protective cover 16, and the protective cover 16 protects the rocker drive assembly. A first bearing 13 is provided at the junction of the first rotating rod 9 and the first crank 10. The first bearing 13 provides limiting support for the first rotating rod 9 and reduces the friction between the first rotating rod 9 and the first crank 10, facilitating rotation. A second bearing 14 is provided at the junction of the first crank 10 and the second rotating rod 11. The second bearing 14 provides limiting support for the second rotating rod 11 and reduces the friction between the second rotating rod 11 and the first crank 10, facilitating rotation.
[0019] Specifically, the first support frame 3 and the second support frame 5 are located between the limiting frame 4, and the first support frame 3, the second support frame 5 and the limiting frame 4 are in contact with each other; both the first support frame 3 and the second support frame 5 have circular holes, and the center of each circular hole is on the same straight line as the center of the arc-shaped collection groove 6. The first support frame 3 is located in the middle part of the side of the scrap collection box 1, and the second support frame 5 is located in the middle part of the side of the arc-shaped collection groove 6, so as to ensure that the arc-shaped collection groove 6 can rotate around the central axis of the circular hole of the second support frame 5.
[0020] Specifically, the arc-shaped collection groove 6 is located above the spiral chip removal structure 2. The width of the cleaning groove of the spiral chip removal structure 2 is greater than the width of the multiple through holes 7. When the arc-shaped collection groove 6 shakes, the iron filings in the arc-shaped collection groove 6 will all enter the cleaning groove of the spiral chip removal structure 2 through the multiple through holes 7.
[0021] Working principle: Iron filings on the tool holder fall into the arc-shaped collection groove 6. When a certain amount of iron filings accumulates, the spiral chip removal structure 2 and the drive motor 15 are activated. The drive motor 15 drives the second crank 12 to rotate, and the second crank 12 drives the second rotating rod 11 to rotate around the output shaft of the drive motor 15. This causes the first crank 10 to drive the first rotating rod 9 to swing back and forth. Since the first rotating rod 9 is connected to the arc-shaped collection groove 6, it can drive the arc-shaped collection groove 6 to swing back and forth around the central axis of the circular hole of the second support frame 5. This discharges the iron filings in the arc-shaped collection groove 6 from multiple through holes 7 into the cleaning groove of the spiral chip removal structure 2, which facilitates chip removal from the machine tool.
[0022] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
