Description

Technical Field

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

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device via an information carrier. After processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings.

[0003] Cutting chips generated during CNC machine tool processing need to be cleaned up promptly to avoid affecting the normal operation of the machine tool. Currently, cleaning is mostly done by using tools such as brushes or scrapers to sweep the chips to the machine tool's built-in cleaning area for collection, and then dumping them at the end of each shift. This cleaning method is effective for smaller chips, such as those from the machining of copper workpieces, because copper has good machinability and is easy to cut, especially brass, whose chips are usually very small. However, for some longer workpieces, such as aluminum or iron workpieces, the cutting chips vary in length. Aluminum and iron have relatively high toughness, and especially under the influence of high cutting temperatures, thin chips are more difficult to break. Longer chips are not conducive to accumulation, so the cleaning frequency needs to be increased. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A chip cleaning device for CNC machine tools includes a CNC machine tool body. A central opening is pre-set on the CNC machine tool body corresponding to the machining area. A cleaning box is placed inside the CNC machine tool body directly below the central opening. Two parallel rotary rollers, roller one and roller two, are installed on the CNC machine tool body above the cleaning box at the position corresponding to the central opening. Multiple equally spaced cutter blades are fixedly installed on each of the rotary rollers roller one and roller two. The cutter blades on the rotary rollers roller one and roller two are paired and close to each other.

[0006] Furthermore, motor one and motor two are respectively installed on the CNC machine tool body at the right end of the first rotating roller and the left end of the second rotating roller. The output ends of motor one and motor two are fixedly connected to the corresponding rotating roller one and rotating roller two. The rotating rollers are rotated by motor drive, which is a mature technology and a simple driving method.

[0007] Furthermore, two rotating rollers are positioned between two rotating rollers. The two rotating rollers can be paired with the two rotating rollers to form groups, and the groups rotate relative to each other to cause the blades to perform shearing.

[0008] Furthermore, pulleys are installed at the left end of the second roller and the right end of the first roller. A second transmission belt is installed on the pulleys of the two second rollers, and a first transmission belt is installed on the pulleys of the two first rollers. Shaft seats are installed on the CNC machine tool body at the corresponding ends of each first and second roller, and each first and second roller is fixedly mounted to its corresponding shaft seat. Utilizing the linkage of the transmission belts, a single motor can drive either one of the first or second rollers to rotate at a time.

[0009] Furthermore, a separation box is placed on top of the cleaning box, and a filter screen is fixedly installed inside the separation box near the bottom. The combination of the filter screen and the separation box can separate the cutting fluid from the falling debris, and then recover the separated cutting fluid.

[0010] Furthermore, a second protrusion is fixedly installed on the outer top of the cleaning box, and a first protrusion is fixedly installed on the inner bottom of the separation box. The positions of the first and second protrusions are staggered. The staggered combination of the two protrusions can form mutual restraint, preventing the separation box from sliding and falling off the cleaning box.

[0011] Furthermore, fixed seats are installed on both the left and right sides of the cleaning box within the CNC machine tool body. Rollers are mounted on the fixed seats, and a chain is mounted on the rollers. At least three support blocks are fixedly mounted on the chain. External hanging strips are fixedly mounted on both sides of the cleaning box, and the support blocks are dragged to the bottom of the external hanging strips to form support. The rotation of the chain drives the support blocks to reciprocate, and the support blocks can support the cleaning box, thus providing reciprocating cyclic support without the need for return to reset.

[0012] Furthermore, the fixed base is equipped with two belt rollers, one upper and one lower, and the chain belt is mounted on the two belt rollers. Linkage rods extending out of the CNC machine tool body are fixedly mounted on the belt rollers on the upper left and right sides of the cleaning box. A throttle is fixedly mounted at the end of the linkage rod outside the CNC machine tool body. The cooperation between the throttle and the linkage rod facilitates the rotation operation of the belt rollers and the chain belt.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a rotating roller with blades installed below the central inlet of a CNC machine tool. When the roller rotates, the blades work together to cut and shorten the falling debris, especially longer debris. The shorter debris continues to fall and accumulates, which facilitates the accumulation of the shorter debris.

[0015] 2. In this utility model, the cutting fluid and debris can be separated and concentrated by the cooperation of the separation box and the cleaning box. The cutting fluid can be recycled and reused without the need for further separation.

[0016] 3. In this utility model, the separation box and the cleaning box are limited by two staggered convex strips, which improves the stability of the separation box on the cleaning box. At the same time, the structure is simple and easy to pick up and place.

[0017] 4. In this utility model, by setting up a chain and cooperating with the support block and the external hanging strip, two sets of separation boxes and cleaning boxes can be placed at one time. This allows for direct replacement during cleaning and maintenance, which is convenient for operation. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] This application provides a chip cleaning device for CNC machine tools, mainly solving the problem that current CNC machine tool cleaning methods using brushes or scrapers cannot handle longer chips. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-7 Please provide a detailed explanation:

[0028] A chip cleaning device for CNC machine tools includes a CNC machine tool body 1. A central opening 12 is pre-set on the CNC machine tool body 1 corresponding to the machining area. A cleaning box 2 is placed inside the CNC machine tool body 1 directly below the central opening 12. Two parallel rotating rollers 4 and 5 are installed on the CNC machine tool body 1 above the cleaning box 2 at the position corresponding to the central opening 12. A bearing seat 11 is installed at both ends of each rotating roller 4 and 5 on the CNC machine tool body 1. Each rotating roller 4 and 5 is fixedly installed to the bearing seat 11 at the corresponding position. The two rotating rollers 5 are located between the two rotating rollers 4. A pulley 6 is installed at the left end of the two rotating rollers 4 and the right end of the two rotating rollers 4. A transmission belt 13 is installed on the pulley 6 of the two rotating rollers 4, and a transmission belt 7 is installed on the pulley 6 of the two rotating rollers 4.

[0029] Motor 9 and motor 10 are respectively installed on the right end of the first roller 4 and the left end of the second roller 5 on the CNC machine tool body 1. The output ends of motor 9 and motor 10 are fixedly connected to the corresponding first roller 4 and second roller 5. The rotation direction of motor 9 and motor 10 is positive. Multiple blades 8 with equal spacing are fixedly installed on each first roller 4 and second roller 5. The blades 8 on the first roller 4 and second roller 5 are paired and close to each other.

[0030] Cutting chips inside the CNC machine tool body 1 can be directly cleaned to the collection port 12. The chips first fall between the first roller 4 and the second roller 5. Powered by the working power output of the first motor 9 and the second motor 10, and driven by the transmission belts 7 and 13, the two rollers 4 and 5 are connected. Combined with the relative position of the two rollers 5 between the two rollers 4, the rollers 4 and 5 rotate inward in cooperation, causing the blades 8 to shear towards the middle. When the chips, especially the longer chips, fall, they can be cut by the blades 8 into smaller chips. The smaller chips continue to fall into the cleaning box 2, which can be emptied periodically.

[0031] In some embodiments, a separation box 3 is placed on top of the cleaning box 2, and a filter screen 14 is fixedly installed in the separation box 3 near the bottom.

[0032] When the chips fall, they first land on the filter screen 14 inside the separation tank 3. If cutting fluid is used during processing, the filter screen 14 can drain the cutting fluid from the chips. The drained cutting fluid falls into the cleaning tank 2, while the chips remain in the separation tank 3. During cleaning, the chips in the separation tank 3 are emptied, and the cutting fluid in the cleaning tank 2 is poured back into the processing area, entering the machine tool's built-in cutting fluid recovery program.

[0033] In some embodiments, a second protrusion 16 is fixedly installed on the outer top of the cleaning box 2, and a first protrusion 15 is fixedly installed on the inner bottom of the separation box 3. The positions of the first protrusion 15 and the second protrusion 16 are staggered.

[0034] The two staggered protrusions allow the separation box 3 to be positioned and fixed on the cleaning box 2, preventing it from sliding off.

[0035] In some embodiments, a fixed seat 18 is installed inside the CNC machine tool body 1 on both the left and right sides of the cleaning box 2. Two belt rollers 19 are installed on the fixed seat 18, and a chain belt 20 is installed on the two belt rollers 19. At least three support blocks 21 are fixedly installed on the chain belt 20. External hanging strips 17 are fixedly installed on the left and right sides of the cleaning box 2. The support blocks 21 are dragged to the bottom of the external hanging strips 17 to form support. Linkage rods 22 extending out of the CNC machine tool body 1 are fixedly installed on the belt rollers 19 above the left and right sides of the cleaning box 2. A throttle 23 is fixedly installed at the end of the linkage rod 22 outside the CNC machine tool body 1.

[0036] When in use, two sets of cleaning boxes 2 and separation boxes 3 can be placed at the same time. First, place one set of cleaning boxes 2 so that it rests on the bottom of the CNC machine tool body 1 for support. At the same time, rotate the linkage rod 22 from the throttle 23 position to drive the chain belt 20 to rotate. Adjust the support block 21 so that one of the support blocks 21 on the chain belt 20 is located below the outer hanging strip 17 of the cleaning box 2. Then place the separation box 3 of the same set. Then place the second set of cleaning boxes 2 on the support block 21 above the first set of separation boxes 3 so that the support block 21 drags on the outer hanging strip 17 of the cleaning box 2. Then place the second set of separation boxes 3 so that the second set of cleaning boxes 2 and separation boxes 3 rest on the first set of cleaning boxes 2 and separation boxes 3 for support. At the same time, the support block 21 rests on the bottom of the outer hanging strip 17 of the second set of cleaning boxes 2.

[0037] When the upper cleaning box 2 and separation box 3 are full, they can be pulled out directly. Then, by rotating the linkage rod 22, the lower cleaning box 2 and separation box 3 are moved to the upper part through the chain belt 20. The cleaning box 2 and separation box 3 to be replaced next are placed below to form a replacement. This allows for quick replacement without waiting for cleaning and then putting them back. There is no waiting time in between, which avoids the possibility of debris or cutting fluid dripping into the interior.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
