Description

Technical Field

[0001] This utility model relates to the field of waste collection technology, specifically to a CNC automatic chip receiving device. Background Technology

[0002] In the field of modern machining, especially in the production process of heavy cutting equipment such as large CNC gantry milling machines and machining centers, a large amount of metal chips, commonly known as "iron chips", are generated. These chips are mainly formed by the workpiece material after being cut by the cutting tool. They come in various forms, including ribbon-like, spiral-like, granular, and fine powder produced by grinding. If these chips are not handled in a timely and effective manner, they will not only seriously affect the cleanliness and safety of the working environment, but also directly damage production efficiency and equipment life. Currently, the industry generally relies on manual collection and processing of such chips. Operators periodically use tools such as hooks and shovels to manually shovel the chips scattered around the machine tool or in the pit into handcarts, which are then transported to a centralized storage point. This method is extremely labor-intensive, especially when large equipment is operating continuously, as the amount of chips generated is huge and requires frequent cleaning, which seriously increases the physical burden and working hours of the workers. At the same time, manual cleaning is inefficient and it is difficult to ensure the timely removal of chips, which can easily lead to chip accumulation, affecting the normal operation of the machine tool, and even posing safety hazards such as tripping and scratches.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a CNC automatic chip receiving device in one embodiment of the present invention. The CNC automatic chip receiving device includes a ground 1 and a pit 2 opened in the ground 1. The outer wall of the pit 2 is provided with a toothed groove 24. Support block 3 is set on the inner wall of pit body 2 and forms a support structure; The support frame 4 is detachably connected to the support block 3, and a solid plate 41 and a mesh plate 42 are respectively installed on the support frame 4; The scraping mechanism 5 includes a pushing end 51 and a first driving end 52. The pushing end 51 is slidably connected to the bearing frame 4 and is used to push the waste material on the solid plate 41 onto the mesh plate 42. The end of the pushing end 51 is connected to the first driving end 52, which is engaged in the tooth groove 24. The material handling mechanism 6 includes a waste bin 61 and a second drive end 62. The waste bin 61 is slidably connected to the pit body 2 and located below the mesh plate 42. The second drive end 62 is used to drive the waste bin 61 to move linearly within the pit body 2.

[0019] In this embodiment, the device abandons the traditional manual shoveling method. Through the meshing transmission between the toothed groove 24 on the outer wall of the pit 2 and the first drive end 52, the pushing end 51 is driven to reciprocate on the support frame 4, automatically pushing the chips on the solid plate 41 to the mesh plate 42. Simultaneously, the second drive end 62 drives the waste bin 61 to move linearly within the pit 2, automatically catching the falling chips. The entire process requires no manual intervention to complete the scraping, transfer, and initial collection of chips, fundamentally liberating labor and significantly reducing the physical burden and safety risks for operators. The automated scraping mechanism 5 can remove chips at predetermined points, ensuring timely chip removal and effectively preventing machine tool jamming, poor chip removal, or even machine downtime caused by chip accumulation. This ensures the continuous operation of main processing equipment, such as CNC gantry milling machines. The continuous, stable, and efficient operation significantly improves the overall utilization rate and production efficiency of the production line. The integration of the support frame 4 and the waste bin 61 into the pit 2 below the ground 1 makes full use of the underground space, keeping the workshop ground 1 area clean and unobstructed, which is conducive to other logistics and operational activities. This sunken structure provides a large storage volume for the waste bin 61. Combined with the automated material handling and transfer mechanism, it can realize the centralized and batch processing of chips, thereby greatly reducing the transfer frequency and enabling monthly transfer, further improving management efficiency. In particular, the combination of the solid plate 41 and the mesh plate 42 on the support frame 4 allows smaller chips or oily chips to fall naturally into the waste bin 61 below, while larger chips are pushed by the pusher end 51 and also fall into the waste bin 61 through the mesh plate 42, realizing the effective collection of chips of different shapes.

[0020] In one embodiment, please refer to Figure 1 - Figure 3 To improve the working efficiency of the pushing end 51, the inner wall of the pit 2 is provided with a first sliding groove 21 and a through hole 211. One end of the pushing end 51 is slidably connected in the first sliding groove 21, and the other end passes through the through hole 211 and is connected to the first driving end 52. The support block 3 is provided with a plurality of first screw holes 31, and the bearing frame 4 is provided with a plurality of second screw holes 43 that mate with the first screw holes 31. The bearing frame 4 is threadedly connected to the bearing frame 51. The pushing end 51 includes a connecting plate 511 and a pushing inclined plate 512. One end of the connecting plate 511 is slidably connected to the first groove 21, and the other end passes through the through hole 211 and is connected to the first drive end 52. A pusher plate 512 is fixed on the connecting plate 511. The length of the pusher plate 512 is the same as the width of the bearing frame 4. The first drive end 52 includes a moving motor 521 and a gear 522. The end of the connecting plate 511 is fixed with the moving motor 521. The output end of the moving motor 521 is connected to the gear 522. The gear 522 meshes with the tooth groove 24.

[0021] In this embodiment, by setting a first sliding groove 21 and a through hole 211 on the inner wall of the pit body 2, and sliding one end of the connecting plate 511 in the first sliding groove 21, and the other end passing through the through hole 211 to connect to the moving motor 521, and cooperating with the pushing inclined plate 512, a highly reliable and easy-to-maintain scraping structure is formed. The first sliding groove 21 on the inner wall of the pit body 2 provides a rigid guide rail for the connecting plate 511 of the pushing end 51. One end of the connecting plate 511 slides in the first sliding groove 21, effectively constraining its movement trajectory and preventing shaking, deviation or jamming caused by uneven force during the pushing process. This ensures that the pushing inclined plate 512 can run smoothly and linearly along the predetermined path, thereby achieving uniform and thorough cleaning of the chips on the solid plate 41, avoiding the problem of residual accumulation caused by incomplete scraping, and making the operation of the entire structure more stable and quiet. The bearing frame 4 cooperates with the first screw hole 31 on the support block 3 through the second screw hole 43 on it, and is fixed by a threaded connection. This detachable connection structure allows the support frame 4 and its mounted components such as the solid plate 41 and mesh plate 42 to be easily removed from the pit 2, improving the maintainability of the equipment. The length of the pusher sloping plate 512 is the same as the width of the support frame 4. This size matching ensures that the pusher sloping plate 512 can completely cover the entire width of the support frame 4 during reciprocating motion. Whether the chips are near the sides or the center of the pit 2, they can be effectively pushed, achieving a full-width, no-missing scraping effect, maximizing the clearing of the receiving surface, and providing sufficient space for the next chip to fall in. The first drive end 52 uses the cooperation of a moving motor 521 and a gear 522. The moving motor 521 is directly fixed to the end of the connecting plate 511, and the gear 522 connected to its output shaft meshes with the tooth groove 24 set on the outer wall of the pit 2. When the moving motor 521 starts, the gear 522 rolls on the tooth groove 24, directly converting the rotational motion into the linear reciprocating motion of the connecting plate 511.

[0022] In one embodiment, please refer to Figure 1 - Figure 3 To improve the material handling efficiency of the waste bin 61, a second chute 22 is provided inside the pit body 2 and below the first chute 21. A drive slide rail 23 is provided at the bottom of the pit body 2. The waste bin 61 is slidably connected in the second chute 22 and the drive slide rail 23. A cabinet door 611 is installed on the front of the waste bin 61, and a guide block 612 is provided inside the waste bin 61. Slider blocks 613 are fixed on both sides of the waste bin 61. The sliders 613 are slidably connected in the second chute 22. A slide rail interface 614 that cooperates with the drive slider 613 is also provided at the lower end of the waste bin 61. The second drive end 62 includes a drive motor 621 and a threaded rod 622. The output end of the drive motor 621 is connected to the threaded rod 622, and the waste bin 61 is threadedly connected to the threaded rod 622.

[0023] In this embodiment, the two sides of the waste bin 61 are slidably connected to the second slide groove 22 via fixed sliders 613, while its lower end cooperates with the bottom drive slide rail 23 via slide rail interface 614, forming upper and lower double guiding constraints. This greatly enhances the stability and anti-overturning ability of the waste bin 61 when moving linearly in the pit 2. Even when carrying a large amount of chips or being impacted by the falling material from the mesh plate 42, the waste bin 61 can maintain a precise movement trajectory, avoiding problems such as jamming or friction damage to the pit 2 wall caused by shaking or deviation, ensuring long-term operational reliability. The drive motor 621 outputs... The output shaft drives the threaded rod 622 to rotate, and the threaded rod 622 and the waste bin 61 form a helical pair. When the drive motor 621 rotates forward and reverse, it can accurately drive the waste bin 61 to make reciprocating linear motion within the pit 2. The threaded drive has the advantages of strong load-bearing capacity, good self-locking, and high positioning accuracy, making it very suitable for applications requiring stable push-pull and heavy-load operation. This ensures that the waste bin 61 can reliably move to the receiving station and, after being filled, is smoothly pushed out to a transfer position that is easy to lift or forklift. The waste bin 61 is equipped with a guide block 612. When the chips falling from the mesh plate 42 hit the guide block 612, its... The falling speed and direction are buffered and guided, causing the chips to spread and stack more evenly and orderly into the box, effectively preventing chip accumulation and blockage of the inlet. This maximizes the utilization of the internal volume of the waste bin 61 and increases the single storage capacity. A cabinet door 611 is installed on the front of the waste bin 61, allowing it to be closed to receive chips normally when the waste bin 61 is located in the receiving position inside the pit. When emptying or maintenance is required, the waste bin 61 can be moved entirely to a safe area outside the pit, and then the cabinet door 611 can be opened for manual cleaning or tool-assisted unloading. The presence of the cabinet door 611 also serves as a... The fixed anti-splash function improves the working environment. Any small amount of residual debris or oil can be thoroughly cleaned through the cabinet door 611, making maintenance convenient. The drive threaded rod 622 is set below the waste bin 61 and works in conjunction with the drive slide rail 23 at the bottom, so that the point of application of the driving force is close to the center of gravity of the waste bin 61. This layout effectively reduces the torque and lateral stress generated during the driving process, making the movement of the waste bin 61 more stable. It also reduces the wear of the slider 613, the second slide rail 22 and the drive threaded rod 622 itself, extending the service life of the key components of the entire material handling mechanism 6.

[0024] To better understand this utility model, the following is combined with... Figures 1 to 3The technical solution of this utility model is described in detail as follows: When the gantry milling machine is performing cutting operations, the metal chips generated fall into the support frame 4 of this device through the chip discharge port or guide channel of the machine tool. The chips fall onto the solid plate 41 or mesh plate 42 on the support frame 4. The solid plate 41 is used to receive the chips. Some smaller chips, which are granular or powdery, as well as wet chips mixed with coolant, will pass directly through the mesh plate 42 set on the support frame 4 and fall into the scrap bin 61 directly below it. The mesh plate 42 plays a preliminary physical sorting role. When scraping is required, the moving motor 521 is started, and its output shaft drives the gear 522 to rotate. The gear 522 meshes with the tooth groove 24 set on the outer wall of the pit body 2, converting the rotational motion of the moving motor 521 into... For the horizontal linear movement of the connecting plate 511, the connecting plate 511 slides within the first groove 21 on the inner wall of the pit 2, ensuring a straight and stable movement trajectory. The pushing inclined plate 512, fixed on the connecting plate 511, moves forward together with the connecting plate 511. Since the length of the pushing inclined plate 512 is the same as the width of the bearing frame 4, it can completely and without omission push the chips accumulated on the solid plate 41 forward from one end to the other. The chips pushed by the pushing inclined plate 512 pass over the solid plate 41 and are finally pushed all over the mesh plate 42. The chips then pass through the holes of the mesh plate 42 and fall into the waste bin 61 below. After the pushing inclined plate 512 completes one pushing stroke, the moving motor 521 reverses, and through the reverse meshing of the gear 522 rack, drives the connecting plate 511. The pusher sloping plate 512 retracts to its starting position, ready for the next scraping operation. This completes one full automated scraping process. While the scraping mechanism 5 operates, the waste bin 61, located at the receiving station inside the pit 2, slides within the second slide groove 22 via sliders 613 on both sides. It maintains stability by engaging with the drive slide rail 23 at the bottom of the pit 2 through the lower slide rail interface 614. The waste bin 61 continuously receives all chips falling from the mesh plate 42, including small chips falling directly and large chips pushed by the scraping mechanism 5, achieving centralized, large-capacity chip storage. After a period of accumulation, the drive motor 621 of the second drive end 62 is activated. The drive motor 621 rotates the threaded rod 622. The threaded rod 622 and the waste bin 61 form a helical pair. The rotating threaded rod 622 drives the waste bin 61 to move linearly outward from inside the pit 2 along the track formed by the second slide 22 and the drive slide rail 23 until it is completely moved out to the safe area of ​​the workshop floor 1. The operator can open the cabinet door 611 on the front of the waste bin 61 and use tools to clean the internal chips into the transfer vehicle. After cleaning, the cabinet door 611 is closed, and the waste bin 61 automatically returns to the receiving position under the action of the drive motor 621. Throughout the receiving process, the guide block 612 inside the waste bin 61 plays an important role. When the chips fall at high speed from the mesh plate 42 and hit the guide block 612, the impact force is buffered and the falling direction is guided, causing the chips to spread and pile up inside the bin.This effectively prevents chips from accumulating at the inlet and clogging it, ensuring that the internal space of the waste bin 61 is fully utilized.
