Description

Technical Field

[0001] This utility model relates to the field of CNC machining debris collection technology, and in particular to a device for collecting CNC machining debris. Background Technology

[0002] The core objective of the CNC (Computer Numerical Control) scrap collection device is to achieve automated, efficient, safe, and clean processing of metal or non-metal scraps and cutting fluid generated during the machining process.

[0003] In the prior art, Chinese patent application number 202420603053.1 discloses a CNC lathe machining debris collection device, including a lathe body with a collection hole. A drive rail is fixedly installed on the top of the collection hole, and a movable seat is installed on the drive rail. A slot is formed inside the lathe body, communicating with the collection hole. A filter plate is fixedly installed inside the slot. This invention uses water flow to flush machining debris into the collection hole, where it falls into the slot. The filter plate filters the debris, and the water flows through the filter plate downwards into a circulation mechanism. The debris on the filter plate is flushed by the water flow and gradually moves towards the left-side outlet. A pusher wheel is activated to push the debris outwards, preventing it from accumulating inside the slot and ensuring continuous discharge. This achieves the advantages of the device being convenient, requiring no manual cleaning, and allowing for continuous operation, thus improving work efficiency.

[0004] However, the above-mentioned technical solutions have the problem that the collection frame does not have a filter structure, and cutting fluid will remain on the workpiece debris, resulting in a large amount of cutting fluid loss and making it impossible to collect the cutting fluid again. At the same time, although the filter plate is set at an angle, the workpiece machining debris has poor flowability and is difficult to fall into the collection frame completely and smoothly. Therefore, this application proposes a device for collecting CNC debris to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of a filter structure inside the collection frame, the accumulation of cutting fluid on workpiece debris leading to significant cutting fluid loss, the inability to recollect the cutting fluid, and the poor flowability of workpiece debris despite the inclined filter plate, making it difficult for it to fall smoothly into the collection frame. Therefore, this invention proposes a device for collecting CNC machining debris.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An apparatus for collecting CNC scrap includes an outer casing, and the apparatus further includes:

[0008] The inner box extends from the bottom of the outer box and is fixedly installed between the inner box and the outer box. The inner box has guide plates fixedly installed on the front inner wall and the rear inner wall.

[0009] The first filter screen is installed on the bottom inner wall of the inner box and is inclined. Both the inner box and the outer box have debris outlets on their front inner walls, and the debris outlets cooperate with the first filter screen.

[0010] The collection assembly includes: a collection box, a drain pipe, a second filter screen, and two handles. The collection box is placed on the front side of the outer box, the drain pipe is fixedly connected to the right side of the collection box, the second filter screen is slidably connected inside the collection box, and the bottom ends of the two handles are fixedly installed on the top of the second filter screen, with the bottom of the two handles contacting the top of the collection box.

[0011] A cleaning component is disposed inside the inner casing and engages with the top of the first filter screen.

[0012] As a preferred embodiment of this utility model, a guide plate is fixedly installed on the front side of the outer box, and the guide plate is matched with the debris outlet.

[0013] As a preferred embodiment of this utility model, a handle is fixedly installed on the front side of the collection box.

[0014] As a preferred embodiment of this utility model, a liquid outlet pipe is fixedly connected to the right side of the outer casing, and a water pump is fixedly installed on the liquid outlet pipe.

[0015] As a preferred embodiment of this utility model, the bottom four corners of the collection box are all fixedly equipped with casters.

[0016] As a preferred embodiment of this utility model, the cleaning assembly includes a scraper, two sliders, and two electric slide rails. The bottom end of the scraper contacts the top of the first filter screen. The ends of the two sliders that are close to each other are fixedly installed on the left and right ends of the scraper, respectively. The ends of the two sliders that are far apart from each other penetrate the left and right inner walls of the inner box and extend into the interior of the outer box. The two electric slide rails are fixedly installed on the left and right sides of the inner box, respectively. The sides of the two electric slide rails that are close to each other are slidably installed on the ends of the two sliders that are far apart from each other.

[0017] As a preferred embodiment of this utility model, sliding holes are provided on the left and right inner walls of the inner box, and the ends of the two sliders that are far apart from each other pass through the two sliding holes and are slidably connected to the inner walls of the sliding holes.

[0018] Beneficial effects:

[0019] 1. In order to collect and remove debris from the first filter screen, the bottom of the scraper contacts the top of the first filter screen, and the electric slide rail drives the slider to move the scraper, which automatically removes the debris accumulated on the first filter screen, prevents the first filter screen from clogging and maintains smooth filtration. The slider passes through the inner box and slides with the electric slide rail to ensure that the scraper moves smoothly and improves cleaning efficiency and automation.

[0020] This invention achieves secondary separation of cutting fluid from debris by placing the collection box on the front side of the outer box, with the second filter screen slidingly connected to the inside of the collection box to further filter debris and residual cutting fluid. The handle makes it easy to remove the second filter screen for cleaning, and the drain pipe discharges the recovered cutting fluid. This reduces the waste of cutting fluid and facilitates the reuse of debris, making it highly practical. Attached Figure Description
