They are high-precision and high-efficiency machining equipment. However, existing CNC lathes have some shortcomings. In actual operation, we have found that lathes have problems with guideway protection and chip removal. The chips generated by the machine tool during workpiece turning fall onto the guideways. When the moving parts on the guideways move, they cause friction between the chips and the guideways, accelerating the wear of the guideways. Furthermore, the chips stuck on the guideways are difficult to remove, affecting machining accuracy and the service life of the lathe. Utility Model Content

[0003] The purpose of this utility model is to provide a CNC machine tool with a guide rail that prevents iron filings from wearing down. This is achieved by adding a detachable and retractable rubber sleeve to the guide rail. The rubber sleeve can contract and expand accordingly according to the machine's operation, ensuring normal machine operation while preventing chips from falling onto the guide rail and causing wear. This improves the accuracy of workpiece processing and the service life of the lathe, thus solving the aforementioned technical problems.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A CNC machine tool with guide rail anti-chip wear, comprising a machine housing: a guide rail is provided inside the machine housing, and large slides are slidably installed on both sides of the top of the guide rail.

[0010] Preferably, a connecting plate is fixedly installed on one side of each of the two large slides, and the two connecting plates are threaded onto the two lead screws respectively.

[0011] The beneficial effects of this utility model are: by adding a flexible and retractable rubber sleeve to the guide rail, the rubber sleeve can shrink and expand accordingly according to the machine's operation, ensuring the normal operation of the machine while preventing chips from falling onto the guide rail, avoiding wear caused by chips on the guide rail, improving the workpiece processing accuracy and the service life of the lathe.

[0012] This utility model, through the design of the slot, bolt hole one, and bolt hole two, ensures that during installation, the end of the protective rubber sleeve is pressed into the slot by the mounting bolt.

Please note that, in order to clearly show the structure of the components of the embodiments of this utility model, the drawings are not drawn to the same scale. The same reference numerals are used to indicate the same parts.

[0026] Example 1:

[0027] A CNC machine tool with guide rail anti-chip wear includes a machine housing 1. A guide rail 2 is disposed inside the machine housing 1. Large slides 3 are slidably mounted on both sides of the top of the guide rail 2. Anti-splash guards 4 are disposed on both sides of the top of the guide rail 2, with two anti-splash guards 4 located between the two large slides 3. Each anti-splash guard 4 includes mounting plates 41 fixedly mounted on the two large slides 3. Four mounting plates 41 are fixedly mounted on one large slide 3, and the other two mounting plates 41 are fixed on the same side of the other large slide 3. Connecting devices are fixedly mounted on the four mounting plates 41 on the same large slide 3. The top of the connecting plate 42 is provided with six mounting bolts 45. The side of the connecting plate 42 away from the mounting plate 41 is fixedly installed with protective rubber sleeves 43 by the mounting bolts 45. The two protective rubber sleeves 43 located between the two large slide plates 3 are fixedly installed with connecting plate 44 at the ends away from the connecting plate 42 by the mounting bolts 45. The side of the connecting plate 44 away from the protective rubber sleeves 43 is fixedly installed on one of the large slide plates 3. The side of the two protective rubber sleeves 43 on one side of one of the large slide plates 3 away from the mounting plate 41 is fixedly installed with connecting plate 49 by the mounting bolts 45.

[0028] The specific usage process is as follows: First, the workpiece rotating turret 2 13 will not move on the guide rail 2, while the two large slides 3 can slide on the guide rail 2. The two large slides 3 are driven by two lead screws, motors 7 and lead screws 8. The lead screws 8 drive the two connecting plates 9 to move, and the large slides 3 connected to the connecting plates 9 will also move along the guide rail 2. Thus, the workpiece rotating turret 10 mounted on one of the large slides 3 will also move along with the corresponding large slide 3, allowing the distance between workpiece rotating turret 2 13 and workpiece rotating turret 10 to be adjusted. This allows for the clamping and fixing of workpieces of different lengths. It should be noted that the clamping ends of workpiece rotating turret 2 13 and workpiece rotating turret 10, that is, the opposite ends of workpiece rotating turret 10 and workpiece rotating turret 2 13, can be adjusted by turning a tool. Figure 2As can be seen, both the upper surfaces of the clamping ends of workpiece turret 2 13 and workpiece turret 10 are equipped with special tool insertion holes. During operation, the user can insert a special tool into the insertion hole and rotate it to adjust the opening and closing of the clamping structure. This allows for clamping and fixing of workpieces of different thicknesses, meeting the processing needs of workpieces of different sizes. It should be noted that workpiece turret 10 rotates together with workpiece turret 2 13 by clamping the workpiece. That is, after the workpiece is clamped, the servo motor on the rear side of workpiece turret 2 13 is activated, driving workpiece turret 2 13 to work. The clamping end of workpiece turret 2 13 will drive the workpiece to rotate, and then workpiece turret 10 will rotate under the influence of the workpiece. The clamping end also rotates accordingly. It should be noted that the workpiece turret 10 is used to assist the workpiece turret 2 13 in rotating the workpiece, ensuring the balance and stability of the workpiece rotation during machining. Then, the cutting end of the cutting turret 11 can perform cutting machining on the workpiece. At the same time, the corresponding lead screw drive motor 7 will drive the corresponding lead screw 8 to rotate. The lead screw 8 will drive the corresponding connecting plate 9 to move. The connecting plate 9 will drive the large slide 3 on which the cutting turret 11 is installed to move on the guide rail 2, thereby performing turning machining on the workpiece. At the same time, the cutting fluid nozzle 12 will spray coolant or water to cool the turning part. The chips generated by the turning through the housing 1 will fall from the inside of the guide rail 2 onto the two bases 1 5 and 2 6. During operation, metal shavings would fall into the machine housing 1 and be cleaned after the work is finished. Previously, some shavings would splash onto the guide rail 2 during operation. As the two large slides 3 moved along the guide rail 2, they would push the shavings along it, causing wear and tear on the guide rail 2. This reduced the tightness of the fit between the large slides 3 and the guide rail 2, thus decreasing the stability of the large slides 3. This technical solution, by adding a splash guard 4, prevents the splashed metal shavings from falling onto the guide rail 2 by the protective sleeve 43, thereby preventing wear and tear on the guide rail 2. This improves the workpiece machining accuracy and the lathe's service life. Multiple protective sleeves 43 are detachably installed on the two large slides 3, facing the side of the workpiece rotating tower 13. The protective sleeve 43 is detachably installed on the workpiece rotating tower 13, allowing for replacement if damaged, thus providing real-time protection for the guide rail 2. During installation, the mounting bolt 45 is bolted onto the workpiece rotating tower 13. Then, the end of the protective sleeve 43 facing the mounting bolt 45 is attached to the upper surface of the mounting bolt 45. The mounting bolt 45 is then passed through the bolt hole 47 on the protective sleeve 43 until it is inserted into the bolt hole 48 on the mounting bolt 45. Finally, the mounting bolt 45 is tightened to fix the protective sleeve 43 to the mounting bolt 45. The protective sleeves 43 connected to the connecting plate 42 and the connecting plate 44 are installed in the same manner.Connecting plate 42 and connecting plate 44 are bolted to the mounting plate 41 on the two large slides 3. It should be noted that the mounting plate 41 is bent outwards, thus not affecting the lateral movement of the cutting turret 11. The protective sleeve 43 is semi-enclosed on both sides of the top of the guide rail 2. During installation, the ends of the protective sleeve 43 are pressed into the slots 46 by the mounting bolts 45, preventing it from falling off when stretched, thus ensuring real-time protection of the guide rail 2. The cutting fluid nozzle 12 is used to spray the workpiece and the cutting turret 1 during turning. The cutting tool on plate 1 is cooled by spraying hot water to prevent damage to the tool and workpiece due to high temperatures, ensuring normal machine tool operation. Two connecting plates 9 are threaded onto two lead screws 8, both driven by lead screw drive motors 7. Thus, driven by the lead screw drive motors 7 and lead screws 8, one connecting plate 9 moves one of the large slides 3 and the cutting turret 11 for turning operations. Similarly, the other lead screw drive motor 7 and lead screw 8 move the other connecting plate 9, which in turn moves the other large slide 3 and the workpiece turret 10, ensuring the normal operation of the CNC machine tool.

[0029] Therefore, a flexible, retractable rubber sleeve is added to the guide rail. The rubber sleeve can shrink and expand accordingly according to the machine's operation, ensuring the normal operation of the machine while preventing chips from falling onto the guide rail, avoiding wear caused by chips, improving the workpiece processing accuracy and the service life of the lathe.

[0030] The top of the connecting plate 42 is provided with a slot 46 that matches the protective rubber sleeve 43. The bottom of the inner side of the slot 46 is provided with a bolt hole 48 that matches the mounting bolt 45. Both sides of the surface of the protective rubber sleeve 43 are provided with bolt holes 47 that match the mounting bolt 45.

[0031] Specifically, the design of the slot 46, bolt hole 47, and bolt hole 48 ensures that during installation, the end of the protective sleeve 43 is pressed into the slot 46 by the mounting bolt 45. This prevents the protective sleeve 43 from falling off when stretched, thus ensuring real-time protection of the guide rail 2.

[0032] A workpiece turret 2 13 is fixedly installed on one side of the top of the guide rail 2, a cutting turret 11 is slidably installed on the top of one of the large slides 3, and a workpiece turret 10 is fixedly installed on the top of one of the large slides 3.

[0033] A cutting fluid nozzle 12 is fixedly installed on one side of the top of the cutting turret 11.

[0034] Specifically, the cutting fluid nozzle 12 is used to spray fluid to cool the workpiece and the cutting tool on the cutting turret 11 during turning, so as to prevent the cutting tool and workpiece from being damaged due to high temperature and ensure the normal operation of the machine tool.

[0035] The bottom of the guide rail 2 is fixedly installed on both sides of the base 5 and the base 6 respectively.

[0036] Two lead screw drive motors 7 are fixedly installed at one end of one side of the guide rail 2. A lead screw 8 is fixedly installed on the output shaft of the lead screw drive motor 7. The end of the lead screw 8 away from the lead screw drive motor 7 is rotatably installed on the side of the guide rail 2.

[0037] A connecting plate 9 is fixedly installed on one side of each of the two large slides 3, and the two connecting plates 9 are threaded onto the two lead screws 8 respectively.

[0038] Specifically, the two connecting plates 9 are threaded onto the two lead screws 8, and both lead screws 8 are driven by the lead screw drive motor 7. Thus, driven by the lead screw drive motor 7 and the lead screw 8, one of the connecting plates 9 will drive one of the large slides 3 and the cutting turret 11 to move for turning work. Similarly, the other lead screw drive motor 7 and the lead screw 8 will drive the other connecting plate 9 to move, which will drive the other large slide 3 and the workpiece turret 10 to move, thereby ensuring the normal operation of the CNC machine tool.

[0039] In summary, this CNC machine tool with anti-chip wear guide rails uses a flexible, removable, and extendable rubber sleeve on the guide rails. The sleeve can contract and expand accordingly based on the machine's operation, ensuring normal machine operation while preventing chips from falling onto the guide rails and causing wear. This improves workpiece machining accuracy and extends the lathe's service life.

[0040] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
