Description

Technical Field

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

[0002] During the machining process, CNC machine tools use cutting tools (such as cutting tools and drills) to cut and drill workpieces, generating cutting waste. This waste mainly includes chips, grinding shavings, waste coolant, and lubricating oil. Cutting waste may exist in various forms such as flakes, filaments, and granules. CNC machine tools generate chip waste during machining, and a receiving frame is usually installed at the bottom of the machine tool to collect the waste. During machining, the machine tool sprays coolant, which mixes with the waste and enters the waste frame together. Metal chips can be recycled and reused through smelting, forging, etc., reducing production costs. Waste coolant and lubricating oil can be recycled or used for other industrial purposes after treatment. When it is necessary to clean the chip waste, the coolant needs to be separated from the chips, requiring an additional separation step, which slows down the subsequent cleaning efficiency. Therefore, this application provides a CNC machine tool chip cleaning device to meet this need. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a CNC machine tool chip cleaning device to solve the problem that when it is necessary to clean chip waste, the coolant needs to be separated from the chips, and an additional separation step is required, which leads to a relatively slow subsequent cleaning efficiency.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A CNC machine tool chip cleaning device includes a receiving box, a feeding hopper, and an extrusion mechanism. The feeding hopper is located on the upper surface of the receiving box, and two sets of feeding hoppers are spaced apart, with an extrusion mechanism located between the two sets of feeding hoppers. The extrusion mechanism includes a crossbeam, a drive block, a telescopic cylinder, and a pressure roller. The crossbeam is horizontally arranged, and two sets of symmetrically distributed and relatively sliding drive blocks are located at its bottom. A fixed rod is fixedly connected to the bottom of each drive block, and the fixed rod is vertically arranged with a bottom rod fixedly connected to its other end. The bottom rod is elastically connected to the fixed rod. The pressure roller is located below the drive block. The telescopic cylinder is vertically installed above the crossbeam, and a support frame is fixedly installed on the outer wall of the telescopic cylinder. The support frame is fixedly connected to the upper surface of the receiving box. A separation mechanism is located in the center of the interior of the receiving box. The separation mechanism includes a partition plate and a drive rod. The surface of the partition plate has a mesh structure, and its outer wall is fixedly connected to the drive rod. Thanks to the extrusion mechanism, when the waste enters the upper surface of the separator plate, it can be quickly rolled. After the waste is extruded, the cutting fluid adhering to the surface flows down and is discharged through the drain pipe, realizing the rapid separation of solid and liquid on the waste.

[0006] Optionally, the drive rod has an L-shaped structure, and a support rod is movably connected to the end away from the partition plate. The support rod is horizontally and fixedly installed on the outer wall of the receiving box.

[0007] Optionally, the support rod has a hollow structure inside, and a drive screw is rotatably mounted inside.

[0008] Optionally, the end of the drive rod that penetrates into the support rod has a threaded hole, and the drive screw is adapted to the threaded hole.

[0009] Optionally, a drive motor is fixedly installed on the outer wall of the support rod, and the drive motor is connected to the drive screw.

[0010] Optionally, the bottom rod has a hollow structure inside, and a spring is installed vertically inside. One end of the spring is fixedly connected to the inner wall of the bottom rod, and the other end is fixedly connected to the bottom end of the fixing rod.

[0011] Optionally, a connecting frame is fixedly connected to the bottom of the base rod. The connecting frame has a U-shaped structure, and the pressure roller is rotatably installed on the inner side of the connecting frame.

[0012] Optionally, a horizontal groove is provided at the bottom of the crossbeam, and an internal screw is rotatably embedded in the groove. The threads on the outer wall of the internal screw are arranged in opposite directions, and the drive block is threadedly connected to the internal screw.

[0013] Optionally, a rotary motor is fixedly installed at the center of the outer wall of the crossbeam, and a drive bevel gear is connected to the output shaft of the rotary motor. A driven bevel gear is fixedly sleeved at the center of the inner screw, and the drive bevel gear and the driven bevel gear are vertically distributed and mesh with each other.

[0014] Optionally, the receiving box has a drain pipe on its bottom outer wall.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, thanks to the extrusion mechanism, when the waste material enters the upper surface of the separator plate, it can be quickly rolled. After the waste material is extruded, the cutting fluid adhering to the surface flows down and is discharged through the drain pipe, realizing the rapid separation of solid and liquid on the waste material. After the solid-liquid separation, the separator plate can be removed from the receiving box to collect the dried waste material on the separator plate. It is convenient to use and saves processes. When the machine tool is processing, the received waste material can be quickly cleaned up, with high cleaning efficiency and reduced working steps. Subsequently, workers can directly collect the dried waste material. It is highly practical and can be widely promoted. Attached Figure Description

[0030] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a CNC machine tool chip cleaning device, including a receiving box 1, a feeding hopper 3 and an extrusion mechanism 2. The feeding hopper 3 is disposed on the upper surface of the receiving box 1, and two sets of feeding hopper 3 are spaced apart, with the extrusion mechanism 2 disposed between the two sets of feeding hopper 3.

[0031] The extrusion mechanism 2 includes a crossbeam 8, a drive block 7, a telescopic cylinder 12, and a pressure roller 5. The crossbeam 8 is horizontally arranged, and two sets of symmetrically distributed and relatively sliding drive blocks 7 are provided at the bottom. A fixed rod 11 is fixedly connected to the bottom of the drive block 7. The fixed rod 11 is vertically arranged, and a bottom rod 10 is fixedly connected to the other end. The bottom rod 10 is elastically connected to the fixed rod 11. The pressure roller 5 is located below the drive block 7. The telescopic cylinder 12 is vertically installed above the crossbeam 8. A support frame 13 is fixedly installed on the outer wall of the telescopic cylinder 12. The support frame 13 is fixedly connected to the upper surface of the receiving box 1.

[0032] A separation mechanism 4 is centrally located inside the receiving box 1. The separation mechanism 4 includes a partition plate 15 and a drive rod 17. The surface of the partition plate 15 has a mesh structure, and its outer wall is fixedly connected to the drive rod 17. A horizontal groove is opened at the bottom of the crossbeam 8, and an internal screw is rotatably embedded in the groove. The threads on the outer wall of the internal screw are arranged in opposite directions, and the drive block 7 is threadedly connected to the internal screw. A rotary motor 9 is fixedly installed centrally on the outer wall of the crossbeam 8. A drive bevel gear is connected to the output shaft of the rotary motor 9, and a driven bevel gear is fixedly sleeved centrally on the internal screw. The drive bevel gear and the driven bevel gear are vertically distributed and mesh with each other. A drain pipe is provided on the bottom outer wall of the receiving box 1.

[0033] like Figure 3 As shown, the bottom rod 10 has a hollow interior, and a spring 14 is vertically installed inside. One end of the spring 14 is fixedly connected to the inner wall of the bottom rod 10, and the other end is fixedly connected to the bottom end of the fixing rod 11. A connecting frame 6 is fixedly connected to the bottom of the bottom rod 10. The connecting frame 6 has a U-shaped structure, and the pressure roller 5 is rotatably installed inside the connecting frame 6.

[0034] like Figure 4 As shown, the drive rod 17 has an L-shaped structure, and a support rod 18 is movably connected to the end away from the partition plate 15. The support rod 18 is horizontally and fixedly installed on the outer wall of the receiving box 1. The support rod 18 has a hollow structure inside, and a drive screw 16 is rotatably installed inside. A threaded hole is opened at the end of the drive rod 17 that passes through the support rod 18, and the drive screw 16 is adapted to the threaded hole. A drive motor 19 is fixedly installed on the outer wall of the support rod 18, and the drive motor 19 is connected to the drive screw 16.

[0035] The working principle of the technical solution provided by this utility model is as follows: When in use, the receiving box 1 is first moved to the bottom of the machine tool, and the discharge port of the machine tool is connected to the feed hopper 3. When the waste falls, it can directly enter the receiving box 1. The waste is intercepted by the partition plate 15. The telescopic cylinder 12 extends and drives the crossbeam 8 to descend, so that the pressure roller 5 approaches the upper surface of the partition plate 15 and contacts the waste. At this time, the rotary motor starts and drives the internal screw inside the crossbeam 8 to rotate. The threads on the outer wall of the internal screw are set in opposite directions, so the two drive blocks 7 are subjected to force and move relative to each other, so that the pressure roller 5 rolls back and forth on the waste on the upper surface of the partition plate 15. After the waste is squeezed, the cutting fluid adhering to the surface flows down and is discharged through the drain pipe.

[0036] After the waste material is separated into solid and liquid, the drive motor 19 can be started. The drive motor 19 will rotate the drive screw 16, and then the drive rod 17 will be moved out along the inside of the support tube. The partition plate 15 can then be moved out of the receiving box 1 to collect the dried waste material on the partition plate 15.

[0037] When the pressure roller 5 contacts the partition plate 15, the bottom rod 10 retracts toward the fixed rod 11, and the spring 14 is compressed, so that the pressure roller 5 has toughness when rolling the waste material, which can avoid excessive pressure from damaging the partition plate 15.

[0038] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
