Description

Technical Field

[0001] This utility model relates to the field of CNC milling machine technology, specifically to a chip removal device for CNC milling machines. Background Technology

[0002] As we all know, CNC milling machines are machine tools that use a CNC system to control the movement of cutting tools and worktables to achieve automated cutting and machining. They have high precision, high efficiency and strong adaptability, and can complete a variety of processes such as milling and drilling. They are widely used in machinery, automobiles, aerospace and other fields, and are the core equipment of modern manufacturing. However, the milling cutter on the milling machine will continuously generate chips when cutting parts, which need to be cleaned.

[0003] Existing chip removal equipment for CNC milling machines is mostly scraper-type chip conveyors. However, since the scrapers of scraper-type chip conveyors are often made of metal, when they come into contact with the operating table to scrape off metal chips, the metal chips may scratch the operating table, thereby increasing maintenance costs and affecting chip removal efficiency. Summary of the Invention

[0008] Preferably, a support plate is provided on the outer side of the fixed column, and two sets of parallel first springs are provided on the side of the support plate near the horizontal plate. A movable plate is provided on the end of the first spring away from the support plate, and one side of the movable plate is in contact with one side of the guide plate.

[0009] Furthermore, two sets of mounting plates are respectively provided on both sides of the horizontal plate, and a movable shaft is provided between the two sets of mounting plates. The swing plate is rotatably positioned outside the movable shaft.

[0010] Furthermore, a central shaft is provided on one side of the swing plate, and a pulley is rotatably provided on the outer side of the central shaft.

[0011] In a further embodiment, two sets of parallel buffer pads are provided on the side of the horizontal plate near the guide plate, and the buffer pads are rubber buffer pads.

[0012] Based on the aforementioned scheme, a second spring is provided on one side of the slider, and the end of the second spring away from the slider is located inside the horizontal plate.

[0024] 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.

[0025] See Figures 1-3 A chip removal device for a CNC milling machine includes a milling machine body 1. A fixed shaft 6 is bolted to the inside of the milling machine body 1. A discharge port 5 is opened on the right side of the milling machine body 1. A guide plate 4 is rotatably connected to the outside of the fixed shaft 6. The guide plate 4 is inclined and parallel to the discharge port 5. The top of the guide plate 4 receives the chips cut by the milling cutter. The chips are discharged from the milling machine body 1 through the discharge port 5 due to gravity. When the chips accumulate, the up-and-down swing of the guide plate 4 will vibrate the chips, thereby quickly discharging the chips. An adjustment component 2 is provided inside the milling machine body 1, and the guide plate 4 is slidably connected to the outside of the adjustment component 2. A drive component 3 is provided inside the adjustment component 2.

[0026] First, refer to Figures 2 to 5In this embodiment, the adjustment assembly 2 includes a fixed column 201 disposed inside the milling machine body 1. A guide plate 4 is slidably connected to the outside of the fixed column 201. A horizontal plate 203 is welded to the top of the fixed column 201. Two sets of parallel buffer pads 209 are disposed on the side of the horizontal plate 203 near the guide plate 4. The buffer pads 209 are rubber buffer pads, which can protect the guide plate 4 and prevent the left side of the guide plate 4 from being damaged by impacting the horizontal plate 203 during retraction. Two sets of sliders 215 are slidably connected inside the horizontal plate 203. A top roller 213 is welded to one side of the slider 215, and a protrusion 212 is welded to the side of the slider 215 away from the top roller 213. Two sets of mounting plates 205 are welded to both sides of the horizontal plate 203. A movable shaft 206 is disposed between the two sets of mounting plates 205. A swing plate 204 is rotatably connected to the outside of the movable shaft 206. A central shaft 208 is fixedly installed at the bottom of the swing plate 204. A pulley 207 is rotatably connected to the outside of the central shaft 208. The outside of the pulley 207 contacts the top of the guide plate 4. A support plate 202 is welded to the outside of the fixed column 201. Two sets of first springs 211 are installed at the top of the support plate 202. A movable plate 210 is installed at the top of the first spring 211. The top of the movable plate 210 contacts the bottom of the guide plate 4. Thus, when the left side of the guide plate 4 is pushed down, the movable plate 210 will be squeezed by the guide plate 4. At this time, the first spring 211 will be squeezed by the movable plate 210. When the left side of the guide plate 4 is no longer pushed, the first spring 211 will drive the left side of the guide plate 4 to move back by springing the movable plate 210 back, thereby causing the left side of the guide plate 4 to move up quickly, thus ensuring the up and down swing of the guide plate 4.

[0027] Then, refer to Figure 5 In this embodiment, a second spring 214 is provided on one side of the slider 215. The end of the second spring 214 away from the slider 215 is located inside the horizontal plate 203. When the slider 215 is pushed, the second spring 214 will be pushed by the slider 215. When the slider 215 is no longer pushed, the second spring 214 will drive the top roller 213 to move back by bouncing the slider 215 back, so that the top roller 213 moves back and no longer pushes the swing plate 204.

[0028] Secondly, see Figure 5In this embodiment, two sets of limiting rods 217 are provided inside the horizontal plate 203. The slider 215 is slidably disposed on the outside of the limiting rods 217. A blocking plate 216 is provided on the outside of the limiting rods 217. The blocking plate 216 can prevent the slider 215 from moving excessively and avoid the slider 215 from hitting the horizontal plate 203. By setting the limiting rods 217, on the one hand, the limiting rods 217 maintain the balance of the slider 215 during movement and prevent the slider 215 from becoming unbalanced and wobbling during movement, thus ensuring the normal displacement of the slider 215. On the other hand, the limiting rods 217 restrict the direction of the slider 215 and prevent the device from failing due to the misalignment of the slider 215, thus ensuring the normal use of the device.

[0029] When the protrusion 212 is pushed, the protrusion 212 will drive the slider 215 to move. The movement of the slider 215 will drive the top roller 213 to move and push the top of the swing plate 204. At this time, the swing plate 204 will swing around the movable shaft 206 as the axis, so that the bottom of the swing plate 204 will drive the pulley 207 to swing downward and push the left side of the guide plate 4, causing the left side of the guide plate 4 to move down. When the protrusion 212 is no longer pushed, the second spring 214 will spring the slider 215 back to move so that the top roller 213 will no longer push the swing plate 204. At this time, the first spring 211 will drive the left side of the guide plate 4 to move back by springing the movable plate 210 back, so that the left side of the guide plate 4 will move up quickly. This causes the guide plate 4 to vibrate the chips on its top during the up and down swing, so that the chips are discharged from the milling machine body 1 through the discharge port 5.

[0030] Finally, see Figures 4 to 6 In this embodiment, the drive assembly 3 includes a rotary motor 301 disposed inside the fixed column 201. The rotary motor 301 is a bidirectional motor, and its output end can rotate forward or backward. The output end of the rotary motor 301 is key-connected to a threaded tube 302. A placement plate 305 is screwed onto the outer side of the threaded tube 302. The placement plate 305 has a threaded hole inside that matches the thread on the outer side of the threaded tube 302. When the threaded tube 302 rotates, the placement plate 305 screwed onto its outer side will move upward or downward. The operator can control the rotation direction of the output end of the rotary motor 301. The movement direction of the placement plate 305 is controlled. Top blocks 304 are provided on both sides of the placement plate 305. The outer side of the top block 304 contacts the outer side of the protrusion 212. The top block 304 is a circular top block. Two sets of balance bars 303 are welded to the top of the horizontal plate 203. The placement plate 305 is slidably connected to the outer side of the two sets of balance bars 303. When the rotary motor 301 is turned on and its output end drives the threaded tube 302 to rotate, the rotation of the threaded tube 302 will drive the placement plate 305 to move linearly. The movement of the placement plate 305 will drive the top block 304 to move and push the protrusion 212 to move laterally.

[0031] This chip removal device for CNC milling machines works by cooperating between the swing plate 204 and the guide plate 4. When the swing plate 204 swings, the guide plate 4 is pushed and moved downwards. When the swing plate 204 moves back, the guide plate 4 moves back. Thus, the up-and-down swing of the guide plate 4 vibrates the chips on its top, causing the chips to be discharged from the milling machine body 1 through the discharge port 5. This avoids the accumulation of chips and prevents the device from being scratched, ensuring the normal operation of the chip removal work.

[0032] Working principle:

[0033] In operation, the chip removal device for this CNC milling machine is first placed in the desired position. Then, the chips produced by the milling cutter fall onto the top of the guide plate 4. Because the guide plate 4 is inclined, the chips slide on it due to gravity and are discharged from the milling machine body 1 through the discharge port 5. When chips accumulate, the rotary motor 301 is turned on, causing its output end to drive the threaded tube 302 to rotate in both directions. The rotation of the threaded tube 302 causes the placement plate 305 to move linearly. The movement of the placement plate 305 causes the top block 304 to move and push the protrusion 212 to move laterally. When the placement plate 305 moves back, it causes the top block 304 to move back and no longer pushes the protrusion 212. When the protrusion 212 is pushed, it will drive the sliding... When block 215 is displaced, the movement of slider 215 will drive top roller 213 to move and push the top of swing plate 204. At this time, swing plate 204 will swing around movable shaft 206 as the axis, so that the bottom of swing plate 204 drives pulley 207 to swing downward and push the left side of guide plate 4, causing the left side of guide plate 4 to move down. When protrusion 212 is no longer pushed, second spring 214 springs slider 215 back to make top roller 213 no longer push swing plate 204. At this time, first spring 211 will drive left side of guide plate 4 back by springing movable plate 210 back, so that left side of guide plate 4 moves up quickly. Thus, guide plate 4 vibrates the chips on its top during up and down swing, so that the chips are discharged from milling machine body 1 through discharge port 5.
