Description

Technical Field

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

[0002] During CNC machine tool processing, the cutting tool generates a large amount of chips (such as iron chips, aluminum chips, etc.) when cutting the workpiece, accompanied by a large amount of cutting fluid spraying to achieve the purpose of cooling, lubrication and chip removal. If these waste materials mixed with chips and cutting fluid are not treated in time, they will not only affect the cleanliness of the processing area, but may also lead to chip accumulation inside the machine tool, wear of guide rails, blockage of the cooling system, and even equipment failure or safety hazards.

[0003] Currently, most CNC machine tools are equipped with chip conveyors to transport chips from the machining area to an external chip collection box. However, chip conveyors often directly handle the mixture of chips and cutting fluid, lacking an effective separation mechanism. This results in a large amount of cutting fluid being discharged along with the chips, making it impossible to recycle and increasing production costs. Although some equipment has a filtration structure, the chips on the filter screen often rely on manual cleaning periodically. This can lead to chips accumulating on the filter screen and not being cleaned in time, which can cover the filter holes, making liquid penetration difficult, affecting separation efficiency, and even causing liquid overflow. Furthermore, the accumulation of chips can also cause blockage, resulting in poor chip removal. Therefore, we propose a chip conveyor device for CNC machine tools. Utility Model Content

[0004] The purpose of this utility model is to provide a chip removal device for CNC machine tools, in order to solve the problems mentioned in the background art. Most chip removal devices directly handle the mixture of chips and cutting fluid, lacking an effective separation mechanism. This results in a large amount of cutting fluid being discharged along with the chips, which cannot be recycled, increasing production costs. Although some devices are equipped with a filtration structure, the chips on the filter screen mostly rely on manual cleaning periodically. This may lead to the accumulation of chips on the filter screen, which cannot be cleaned in time, thus covering the filter holes, making it difficult for liquid to penetrate, affecting the separation efficiency, and even causing liquid to overflow. Furthermore, the accumulation of chips may also cause blockage, resulting in poor chip removal.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chip removal device for a CNC machine tool, comprising: a chip conveyor; It also includes: a separation component, which is located on one side of the chip conveyor. The separation component is used to separate the chips from the cutting fluid, guide the separated chips to the chip conveyor for chip removal, and collect the separated cutting fluid. The chip scraper assembly is located on one side of the chip conveyor and is used to reciprocate scraping the chips separated by the separation assembly. The separation component includes a base, two support seats are fixedly connected to the upper side of the base, a box is fixedly connected to the upper side of the support seats, an annular frame is fixedly connected to the inner side of the box, and a filter screen is fixedly connected to the inner side of the annular frame.

[0006] The box body is fixedly connected to a guide plate on the side near the chip conveyor, and a chip discharge port is opened at the guide plate.

[0007] The base has a liquid storage tank fixedly connected to its upper side, and a drain valve is installed on the lower side of the liquid storage tank.

[0008] The lower side of the tank is fixedly connected to the liquid storage tank by a connecting pipe. The lower side of the tank is set as a downward slope facing the connecting pipe, and the connecting pipe is inclined towards the liquid storage tank.

[0009] The chip scraping assembly includes a bracket fixedly connected to the upper side of the base, a mounting shell fixedly connected to the upper side of the bracket, a motor fixedly connected to the inner side of the mounting shell, and a reciprocating screw that rotates with the mounting shell fixedly connected to the output end of the motor.

[0010] The reciprocating screw is equipped with a connector, which cooperates with the reciprocating screw. A first guide rod that slides with the connector is fixedly connected to the inner side of the mounting housing.

[0011] The connector has a connecting rod that is fixedly connected to one side of the mounting housing and moves through the side of the mounting housing. A second guide rod that slides with the connecting rod is fixedly connected to the inside of the mounting housing. A through groove adapted to the connecting rod is opened on one side of the mounting housing. The connecting rod slides along the through groove. A scraper that slides with the annular frame is fixedly connected to one end of the connecting rod.

[0012] The chip conveyor is fixedly connected to baffles on both sides near the housing.

[0013] This utility model has at least the following beneficial effects: This invention utilizes a separation component to effectively separate the waste chips and cutting fluid mixture entering the housing. The separated waste chips are guided to a chip conveyor for removal, while the separated cutting fluid is collected for recycling. A scraping component reciprocates the waste chips separated by the separation component to prevent clogging and maintain separation efficiency. It also ensures smooth discharge of the separated waste chips to the chip conveyor and prevents their accumulation on the conveyor, which could overload the conveyor belt, cause blockages or jams, hinder transport, and prevent timely chip removal.

[0016] 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.

[0017] Example 1 Please see Figures 1 to 4 This utility model provides a technical solution: a chip removal device for a CNC machine tool, comprising: a chip conveyor 11; It also includes: a separation component 2, which is disposed on one side of the chip conveyor 11. The separation component 2 is used to separate the chips from the cutting fluid, guide the separated chips to the chip conveyor 11 for chip discharge, and collect the separated cutting fluid. The chip scraper assembly 3 is located on one side of the chip conveyor 11 and is used to reciprocate scraping the chips separated by the separation assembly 2. The chip conveyor 11 is installed on one side of the machine tool bed to receive waste chips from the separation component 2 and transport them to the chip collection box or an external collection container to achieve continuous chip removal. Through the separation component 2, the waste chips and cutting fluid mixture entering the box 23 can be effectively separated, and the separated waste chips are guided to the chip conveyor 11 for chip removal. The separated cutting fluid is collected and recycled. The chip scraper 3 can scrape the waste chips separated by the separation component 2 back and forth to prevent clogging and maintain separation efficiency. At the same time, it can also ensure that the separated waste chips are smoothly discharged to the chip conveyor 11 and prevent the waste chips from accumulating on the chip conveyor 11 after being discharged to the chip conveyor 11, which would cause the conveyor belt of the chip conveyor 11 to be overloaded, or even clogged or jammed, hindering the conveying and preventing the chips from being removed in time.

[0018] The separation component 2 includes a base 21, which can be fixed on a support surface such as the ground. Two support seats 22 are fixedly connected to the upper side of the base 21. A box 23 is fixedly connected to the upper side of the support seats 22. An annular frame 24 is fixedly connected to the inner side of the box 23. A filter screen 25 is fixedly connected to the inner side of the annular frame 24. A guide plate 27 is fixedly connected to the side of the box 23 near the chip conveyor 11. A chip discharge port 26 is opened at the guide plate 27 of the box 23.

[0019] The mixture of waste chips and cutting fluid is discharged into the housing 23. Under the action of gravity, the liquid flows downward through the filter screen 25, while the waste chips are intercepted on the upper side of the filter screen 25. Some of the waste chips can be discharged from the housing 23 through the chip discharge port 26 under the action of gravity, and guided to the chip conveyor 11 by the guide plate 27.

[0020] A liquid storage tank 28 is fixedly connected to the upper side of the base 21. A drain valve 210 is provided on the lower side of the liquid storage tank 28. A connecting pipe 29 is fixedly connected between the lower side of the tank body 23 and the liquid storage tank 28. The lower side of the tank body 23 is set as an inclined surface facing downward toward the connecting pipe 29. The connecting pipe 29 is inclined toward the liquid storage tank 28.

[0021] The cutting fluid filtered by the filter screen 25 flows to the bottom of the housing 23. The inclined surface of the bottom of the housing 23 guides the cutting fluid to the connecting pipe 29. The inclined setting of the connecting pipe 29 allows the cutting fluid to flow into the storage tank 28 for collection, preventing liquid accumulation. The cutting fluid collected in the storage tank 28 can be discharged by opening the drain valve 210. Alternatively, a return pump can be connected to achieve automatic circulation and reuse.

[0022] The scraper assembly 3 includes a bracket 31 fixedly connected to the upper side of the base 21. A mounting shell 32 is fixedly connected to the upper side of the bracket 31. A motor 33 is fixedly connected to the inner side of the mounting shell 32. A reciprocating screw 34 rotatably connected to the output end of the motor 33 is fixedly connected to the mounting shell 32. The mounting shell 32 can protect the internal components.

[0023] A connector 35 is provided on the reciprocating screw 34. The connector 35 cooperates with the reciprocating screw 34 and can reciprocate when the reciprocating screw 34 rotates. A first guide rod 36 is fixedly connected to the inner side of the mounting shell 32 and is slidably arranged with the connector 35. It can guide and limit the movement of the connector 35.

[0024] A connecting rod 38 is fixedly connected to one side of the connector 35 and extends through the side of the mounting housing 32. A second guide rod 37 is fixedly connected to the inside of the mounting housing 32 and slides along the connecting rod 38. This guide rod 37 can guide and limit the movement of the connecting rod 38, thereby improving the stability of movement. A through groove 39 adapted to the connecting rod 38 is opened through one side of the mounting housing 32. The connecting rod 38 slides along the through groove 39. A scraper 310 is fixedly connected to one end of the connecting rod 38 and slides along the annular frame 24. The scraper 310 spans above the filter screen 25, and the bottom of the scraper 310 makes slight contact with the surface of the filter screen 25 or leaves a small gap.

[0025] By controlling the operation of motor 33, the output end of motor 33 drives the reciprocating screw 34 to rotate, which in turn drives the connecting piece 35 to reciprocate along the first guide rod 36, and drives the connecting rod 38 to reciprocate along the second guide rod 37. This causes the scraper 310 to reciprocate on the surface of filter screen 25, scraping the waste chips accumulated on the upper side of filter screen 25, so that the accumulated waste chips are discharged through the chip discharge port 26 and guided to the chip conveyor 11 via the guide plate 27. In addition, by controlling the operating power of motor 33, the frequency of reciprocating movement of scraper 310 can also be adjusted to adapt to different processing intensities. At the same time, the reciprocating scraping of scraper 310 can also move the waste chips, preventing the waste chips from accumulating on the chip conveyor 11 after discharge, which would cause the conveyor belt of chip conveyor 11 to be overloaded, or even blocked or jammed, hindering the conveying and preventing the chips from being removed in time.

[0026] Example 2 Baffles 41 are fixedly connected to both sides of the chip conveyor 11 near the housing 23. The baffles 41 can block the waste chips guided to the chip conveyor 11 by the guide plate 27, and prevent the waste chips from splashing to the outside of the chip conveyor 11.
