Description

Technical Field

[0001] The present invention relates to the technical field of numerical control equipment, in particular to a numerical control lathe with a waste chip collection function. Background Art

[0002] CNC lathes are one of the most widely used CNC machine tools. They are primarily used for machining internal and external cylindrical surfaces of shafts and discs, internal and external conical surfaces of arbitrary taper angles, complex internal and external rotational curved surfaces, and cylindrical and conical threads. They can also perform grooving, drilling, reaming, reaming, and boring.

[0003] CNC machine tools automatically process parts according to pre-programmed procedures. The machining process, process parameters, tool motion, displacement, cutting parameters, and auxiliary functions are compiled into a machining program sheet in accordance with the instruction code and program format specified by the CNC machine. The contents of this program sheet are then recorded on a control medium and input into the CNC machine's numerical control unit, thereby directing the machine to process the part.

[0004] CNC lathes will generate a large amount of waste cutting fluid and waste chips during processing. Most CNC lathes do not have the function of automatic chip removal and need to use other chip removal equipment. The cutting fluid and waste chips are usually discharged mixed, which makes it difficult to collect them separately. The waste chips of the CNC lathe will be scattered all over the bed during processing, making it inconvenient to clean the waste chips everywhere in the bed. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a CNC lathe with a waste chip collection function, which can quickly separate cutting fluid and waste chips to facilitate subsequent processing.

[0006] To this end, the technical solution of the present invention is: a CNC lathe with a waste chip collection function, including a lathe body, a filter plate provided in the lathe body, and a filter hole provided on the filter plate; a frame-shaped mounting bracket is provided under the filter plate, and slide grooves are provided on both sides of the mounting bracket, and the front and rear edges of the filter plate are inserted into the slide grooves; a vibration motor is provided on the mounting bracket, and the vibration motor is connected to the left side of the filter plate through an eccentric connecting rod, and the vibration motor drives the filter plate to move back and forth along the slide groove through the eccentric connecting rod; the right side of the mounting bracket is rotatably mounted on the lathe body through a first rotating shaft, and a lifting mechanism is provided under the left side of the mounting bracket, and the lifting mechanism drives the mounting bracket and the filter plate to be inclined; a waste liquid tank is provided under the filter plate, and a waste chip storage box is provided on the right side of the waste liquid tank.

[0007] When processing parts, cutting fluid and waste chips fall into the filter plate; the vibration motor starts working, driving the filter plate to move back and forth through the eccentric connecting rod, and the waste chips and cutting fluid on the filter plate are vibrated, causing the cutting fluid to fall into the waste liquid tank, and only waste chips remain on the filter plate; after the parts are processed, the jacking mechanism on the left side of the mounting frame starts working, lifting the left side of the mounting frame, causing the filter plate to tilt downward to the right, and the vibration of the vibration motor shakes the waste chips into the waste chip storage box on the right, thereby quickly separating the cutting fluid and waste chips, and collecting them separately for subsequent processing, saving resources.

[0008] Preferably, the lathe body is equipped with a cutterhead and a positioning fixture. The positioning fixture is mounted on a positioning seat, located below the cutterhead, and a filter tray is located below the positioning seat. The positioning seat is mounted on a horizontally arranged second rotating shaft, which is driven by a rotary motor to cause the positioning seat to flip. The cutterhead can be mounted with a variety of cutting tools, and the appropriate tool can be selected according to needs. During machining, waste chips will remain on the positioning fixture. The rotary motor drives the second rotating shaft to rotate, causing the positioning seat and positioning fixture to flip, allowing waste chips and cutting fluid on the positioning fixture to fall into the filter tray, making it easier for the positioning fixture to clamp the next part to be processed.

[0009] Preferably, the filter disc's filter surface is composed of alternating arcuate grooves and arcuate protrusions, with the filter holes located at the bottom of the arcuate grooves. Sloping baffles are provided on the front and rear sides of the filter disc, and protruding slides are provided at the bottom of the inclined baffles, which are positioned within the slide grooves of the mounting frame. The uneven filter surface of the filter disc allows waste chips to be dispersed by the uneven surface during horizontal movement, shaking off any remaining cutting fluid.

[0010] Preferably, a driving wheel is mounted on the motor shaft of the vibration motor, and the two ends of the eccentric connecting rod are rotatably mounted on the driving wheel and the left side of the filter disc via pins. The connection between the connecting rod and the driving wheel is not aligned with the axis, and the vibration motor drives the driving wheel to rotate, and the connecting rod drives the filter disc to vibrate horizontally.

[0011] Preferably, the lifting mechanism includes a lifting cylinder, the end of which is rotatably mounted on the left side of the mounting frame via a second pin. The lifting cylinder is used to lift the filter tray, facilitating the dumping of waste debris on the filter tray into a waste storage box for recycling.

[0012] Preferably, the waste chip storage box is located on the right side of the lathe body, a waste discharge port is provided on the right side panel of the lathe body, and an inclined guide plate is provided above the waste chip storage box, with one side of the guide plate fixed above the waste discharge port of the lathe body and the other side fixed to the right side of the waste chip storage box. The waste chip storage box is located outside the lathe body, and an opening for waste chip discharge is provided on the right side panel of the lathe body. The guide plate can guide the waste chips into the waste chip storage box to prevent the waste chips from falling outside the waste chip storage box.

[0013] Compared with the prior art, the beneficial effects of the present invention are: a filter disc is arranged inside the lathe body to filter waste chips and separate them from the cutting fluid, and the filter disc can be shaken back and forth to remove the cutting fluid remaining on the waste chips, making the separation more thorough; the positioning seat is set to a rotating structure to remove waste chips on the positioning tooling and ensure processing accuracy; the jacking mechanism can lift the filter disc into an inclined structure, making it convenient for waste chips to fall into the waste chip storage box, thereby realizing the waste chip collection function.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Therefore, the terms "first" and "second" may explicitly or implicitly refer to one or more of these features. Throughout the description of the present invention, "several" and "a number" mean two or more, unless otherwise specifically defined.

[0023] See the accompanying drawings. The CNC lathe described in this embodiment includes a lathe body 1, which is internally provided with a cutterhead 2 and a positioning fixture 3. The positioning fixture 3 is mounted on a positioning seat 4, located below the cutterhead 2. Various cutting tools are mounted on the cutterhead, which rotates and moves downward according to a pre-set program to process parts on the positioning seat. The positioning fixture 3 is adapted to the part to be processed and facilitates the fixing of the part. When the tool processes the part, waste chips will fall onto the positioning fixture and the positioning seat. Therefore, the positioning seat 4 is mounted on a horizontally arranged second rotating shaft 5. The second rotating shaft 5 is driven by a rotating motor 6, which can drive the positioning seat 4 to flip.

[0024] A filter tray 7 is provided in the lathe body 1 and is located below the positioning seat 4; the filtering surface of the filter tray is composed of alternating arc-shaped grooves 71 and arc-shaped protrusions 72, and a plurality of filter holes 73 are provided at the bottom of the arc-shaped grooves 71; the front and rear sides of the filter tray 7 are provided with inclined baffles 74, and the bottom of the inclined baffles is provided with a protruding slide bar 75, and the inclined baffles are open to prevent waste chips from falling.

[0025] A frame-shaped mounting bracket 8 is provided below the filter disc 7. The middle portion of the mounting bracket, opposite the filter surface, is hollow. Horizontal chutes 81 are provided on the front and rear sides of the mounting bracket 8. The slide bars 75 of the filter disc 7 are inserted into the chutes 81 of the mounting bracket and can move along the chutes. A vibration motor 9 is installed on the upper left side of the mounting bracket 8. A driving wheel 10 is mounted on the motor shaft of the vibration motor 9. The two ends of the eccentric connecting rod 11 are rotatably mounted on the driving wheel 10 and the left side of the filter disc 7 via pins. The connection between the connecting rod and the driving wheel is not aligned with the axis. The vibration motor 9 drives the driving wheel 10 to rotate, and the eccentric connecting rod 11 drives the filter disc 7 to move back and forth rapidly along the chutes 81. During the horizontal back-and-forth movement of the filter disc 7, waste chips can be broken up by the uneven filter surface, shaking off the cutting fluid remaining on the waste chips.

[0026] The right side of the mounting frame 8 is rotatably mounted on the lathe body 1 via a first rotating shaft 12. A lifting mechanism is provided below the left side of the mounting frame 8. The lifting mechanism includes a lifting cylinder 13, the end of which is fixed to the left side of the mounting frame. The lifting cylinder 13 can lift the mounting frame 8, causing the mounting frame to tilt about the first rotating shaft 12, thereby causing the filter disc 7 to tilt.

[0027] A waste liquid tank 14 and a waste chip storage box 15 are provided below the filter disc 7. The waste liquid tank is located in the path of the filter surface during movement. That is, during horizontal movement, cutting fluid on the filter surface still drips into the waste liquid tank. The waste chip storage box 15 is located on the right side of the lathe body 1. An opening for waste chip discharge is provided on the right side panel of the lathe body 1. An inclined guide plate 16 is provided above the waste chip storage box 15. One side of the guide plate is fixed to the lathe body 1, and the other side is fixed to the right side of the waste chip storage box 15. The waste chip storage box 15 is located below the right side of the mounting frame 8. When the mounting frame rotates and tilts about the first rotating shaft 12, the waste chip storage box 15 is located at the lowest point of the mounting frame, making it convenient for waste chips to be poured into the waste chip storage box. The guide plate can prevent waste chips from falling outside the waste chip storage box.

[0028] During operation, the part to be processed is placed on the matching positioning fixture 3 and fixed. A variety of cutting tools are installed on the cutter head 2. After selecting the appropriate tool, the part is processed and cutting fluid is sprayed between the tool and the part. At the same time, the waste chips generated by the processing fall into the filter disc 7. The vibration motor 9 starts to work, driving the driving wheel 10 to rotate, so that the eccentric connecting rod 11 can drive the filter disc 7 to move back and forth. The waste chips and cutting fluid on the filter disc 7 are vibrated, causing the cutting fluid to fall into the waste liquid tank 14, leaving only waste chips on the filter disc 7. After the part processing is completed, the rotary motor 6 drives the second rotating shaft 5 to rotate, and the second rotating shaft 5 drives the positioning seat 4 and the positioning fixture 3 to flip and remove the remaining waste chips. Then, the lifting cylinder 13 on the left side of the mounting frame starts to work, raising the left side of the mounting frame. The mounting frame 8 rotates around the first rotating shaft 12, causing the filter disc 7 to tilt downward to the right. The shaking of the vibration motor 9 shakes the waste chips into the waste chip storage box 15 on the right, thereby quickly separating the cutting fluid and waste chips and collecting them separately for subsequent processing, saving resources.
