Description

Technical Field

[0001] This utility model relates to the field of chip removal technology for machine tools, and in particular to a chip removal structure for CNC machine tools. Background Technology

[0002] CNC machine tools, short for numerical control machine tools, are automated machine tools equipped with a program control system. This control system logically processes programs with control codes or other symbolic instructions, decodes them, represents them with coded numbers, and inputs them into the CNC device via an information carrier. After processing, the CNC device sends various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings. CNC machine tools effectively solve the problems of machining complex, precise, small-batch, and multi-variety parts. They are flexible, high-efficiency automated machine tools, representing the development direction of modern machine tool control technology, and are a typical mechatronics product.

[0003] When machining workpieces using CNC machine tools, the generated chips are discharged along with the coolant through the chip conveyor. To make the machining process more energy-efficient and environmentally friendly, it is necessary to separate the metal chips from the coolant for recycling. The mixture of coolant and chips discharged along the CNC machine tool's chip conveyor is generally separated using a filter screen. However, during the long-term filtration process, the number of chips trapped in the filter screen increases continuously, which can clog the coolant flow. Manually cleaning the filter screen is not only inefficient but also poses a risk of cutting fingers from the chips, affecting worker health. Utility Model Content

[0004] The purpose of this application is to provide a chip removal structure for CNC machine tools, in order to solve the problem mentioned in the background art that the mixture of coolant and chips discharged along the chip removal groove of CNC machine tools is generally separated by a filter screen. However, during the long-term separation and filtration process, the number of chips trapped by the filter screen increases continuously, which will block the coolant from being filtered out. Manually cleaning the filter screen is not only inefficient, but also makes it easy to cut fingers with chips, affecting the health of workers.

[0005] To achieve the above objectives, this application provides the following technical solution: a chip removal structure for a CNC machine tool, including a liquid collection tank, a chip collection box fixed to the left side of the liquid collection tank, a drain pipe fixedly connected to the front side of the liquid collection tank, a valve installed on the drain pipe, a reserved slot opened on the front side of the chip collection box, a drawer slidably inserted into the reserved slot, a frame fixed to the top of the liquid collection tank and the chip collection box, and both the liquid collection tank and the chip collection box are interconnected with the frame, a first material hopper fixed to the top of the frame, and the front and rear of the frame... A support rod is provided through the side, and the joint between the frame and the support rod is rotatably connected by a bearing. A fixing block is fixed to the outer wall of the support rod, and a carrier box is fixed on the fixing block. A filter screen is installed at the bottom of the carrier box. A fixing rod is fixed between the front and rear inner walls of the frame. The discharge port of the first material hopper is located directly above the liquid collection tank, and the fixing rod is located directly above the chip collection tank. A drive assembly is installed on the front side of the frame, and a gear is fixedly sleeved on the outside of the support rod. The drive assembly is used to drive the gear to rotate.

[0006] Furthermore, a second material hopper is fixed to the top of the chip collection box.

[0007] Furthermore, grooves are provided on both the front and rear sides of the drawer.

[0008] Furthermore, the drawer is equipped with two latches, which are used to lock the chip box and the drawer.

[0009] Furthermore, a pump is installed on the front side of the collection tank. The inlet of the pump is connected to the collection tank, and the outlet of the pump is fixedly connected to a delivery pipe. A nozzle is installed at the other end of the delivery pipe.

[0010] Furthermore, the drive assembly includes a fixed plate, which is fixedly mounted on the frame. An electric push rod is mounted on the fixed plate, and a carrier block is fixedly mounted on the output end of the electric push rod. A rack is fixedly mounted on the bottom of the carrier block, and the rack meshes with a gear.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] 1. In this utility model, a first hopper is used to receive the mixture of coolant and chips discharged from the chip removal groove of the CNC machine tool. The mixture is discharged along the bottom of the first hopper and falls into the carrier box. The coolant and chips are separated by a filter screen. The coolant filtered by the filter screen can be collected in a collection tank, and the chips trapped on the filter screen can be temporarily stored in the carrier box. When the CNC machine tool is paused for workpiece processing, the drive component can drive the gear to rotate, which drives the support rod, carrier box and filter screen to rotate. After the carrier box flips, the chips temporarily stored inside can fall into the chip collection box for collection. The drive component drives the carrier box to rotate back and forth, causing the carrier box to collide with the fixed rod multiple times. The vibration causes the chips adhering to the filter screen to be shaken off into the chip collection box as much as possible, making the cleaning and collection of chips safer and more efficient.

[0013] 2. In this utility model, the pump can be used to send the coolant collected in the collection tank to the nozzle. The worker can hold the nozzle to flush the inside of the CNC machine tool, so that the debris inside the machine tool can be better discharged along the chip discharge groove with the coolant.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example: Reference Figure 1-6 The chip removal structure of a CNC machine tool shown includes a liquid collection tank 1, a chip collection tank 2 fixed to the left side of the liquid collection tank 1, a drain pipe 3 fixedly connected to the front side of the liquid collection tank 1, a valve installed on the drain pipe 3, a reserved slot opened on the front side of the chip collection tank 2, a drawer 4 slidably inserted into the reserved slot, a carrier frame 5 fixed to the top of the liquid collection tank 1 and the chip collection tank 2, and both the liquid collection tank 1 and the chip collection tank 2 are interconnected with the carrier frame 5, a first material hopper 6 fixed to the top of the carrier frame 5, and support rods 7 extending through the front and rear sides of the carrier frame 5. The frame 5 and the support rod 7 are connected by a bearing. A fixing block 8 is fixed on the outer wall of the support rod 7. A carrier box 9 is fixed on the fixing block 8. A filter screen 10 is installed at the bottom of the carrier box 9. A fixing rod 11 is fixed between the front and rear inner walls of the frame 5. The discharge port of the first hopper 6 is located directly above the liquid collection box 1. The fixing rod 11 is located directly above the chip collection box 2. A drive assembly is installed on the front side of the frame 5. A gear 12 is fixedly sleeved on the outside of the support rod 7. The drive assembly is used to drive the gear 12 to rotate.

[0024] The first hopper 6 receives the mixture of coolant and chips discharged from the chip removal groove of the CNC machine tool. The mixture is discharged along the bottom of the first hopper 6 and falls into the carrier box 9. The coolant and chips are separated by the filter screen 10. The coolant filtered by the filter screen 10 can be collected in the liquid collection tank 1, and the chips trapped on the filter screen 10 can be temporarily stored in the carrier box 9. When the CNC machine tool pauses workpiece processing, the drive component can drive the gear 12 to rotate, so that the gear 12 drives the support rod 7, the carrier box 9 and the filter screen 10 to rotate. After the carrier box 9 flips, the chips temporarily stored inside can fall into the chip collection box 2 for collection. The drive component drives the carrier box 9 to rotate back and forth, so that the carrier box 9 collides with the fixed rod 11 multiple times. The vibration causes the chips adhering to the filter screen 10 to be shaken off into the chip collection box 2 as much as possible, making the cleaning and collection of chips safer and more efficient.

[0025] Among them, the top of the chip collection box 2 is fixed with a second material hopper 13, and the front and rear sides of the drawer 4 are provided with grooves 14. Two latches 15 are installed on the drawer 4, and the two latches 15 are used to lock the chip collection box 2 and the drawer 4.

[0026] The drawer 4 receives the debris falling into the chip collection box 2, making it easier to remove the debris. The two latches 15 help lock the drawer 4 and the chip collection box 2, ensuring the stability of the drawer 4 when receiving debris. The second hopper 13 can better receive the debris poured out of the carrier box 9, allowing it to enter the interior of the drawer 4 better. The two grooves 14 provide a point of leverage for workers to pick up, put down, and move the drawer 4.

[0027] Among them, a pump 16 is installed on the front side of the liquid collection tank 1. The inlet of the pump 16 is connected to the liquid collection tank 1. The outlet of the pump 16 is fixedly connected to the liquid delivery pipe 17. A nozzle 18 is installed at the other end of the liquid delivery pipe 17.

[0028] When the pump 16 is activated, the coolant collected in the collection tank 1 can be sent to the nozzle 18. The worker can hold the nozzle 18 to flush the inside of the CNC machine tool, so that the debris inside the machine tool can be better discharged along the chip discharge groove with the coolant.

[0029] The drive assembly includes a fixed plate 19, which is fixedly mounted on the frame 5. An electric push rod 20 is mounted on the fixed plate 19. A carrier block 21 is fixedly mounted on the output end of the electric push rod 20. A rack 22 is fixedly mounted on the bottom of the carrier block 21. The rack 22 meshes with the gear 12.

[0030] The rack 22 is moved by the electric push rod 20. The rack 22 meshes with the gear 12, which in turn drives the support rod 7 and the other components on it to rotate.

[0031] Working principle of this utility model:

[0032] The carrier frame 5 is placed below the chip removal groove of the CNC machine tool, and the liquid collection box 1, chip collection box 2 and carrier frame 5 are fixed. When the CNC machine tool processes the workpiece, the generated chips will be discharged along the chip removal groove with the coolant. The mixture of chips and coolant falls into the first hopper 6 and can flow out along the bottom of the first hopper 6, and finally fall into the carrier box 9. The filter screen 10 will filter the mixture, so that the chips are trapped in the carrier box 9, and the coolant flows through the filter screen 10 into the interior of the liquid collection box 1 and is collected.

[0033] After the workpiece is processed, before processing the next part, the electric push rod 20 can be operated to pull the rack 22 back and forth. The rack 22 meshes with the gear 12, thus driving the gear 12 and the support rod 7 to rotate. The support rod 7, the carrier box 9, and the filter screen 10 rotate synchronously. The debris trapped inside the carrier box 9 can fall into the second hopper 13 by its own weight after tumbling. When the carrier box 9 touches the fixed rod 11, the carrier box 9 and the filter screen 10 will produce a small amplitude vibration, causing the carrier box 9 and the filter screen 10 to vibrate slightly. The debris adhering to the mesh 10 can be shaken off into the second collection hopper 13. The debris slides down the second collection hopper 13 and eventually falls into the drawer 4 for collection. After that, the electric push rod 20 pulls the carrier box 9 back to its original position and moves it above the liquid collection tank 1. The worker can then activate the pump 16 to send the coolant in the liquid collection tank 1 to the nozzle 18. The coolant sprayed out along the nozzle 18 can flush the inside of the CNC machine tool, allowing the debris remaining inside the machine tool to be better discharged along the chip removal groove.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
