Description

Technical Field

[0001] This utility model relates to the field of machine tool accessories technology, and more specifically, to a sliding guide rail mechanism for machine tools. Background Technology

[0002] As the core equipment of modern manufacturing, the machining accuracy, efficiency, stability, and service life of machine tools largely depend on the performance of key basic components. Among them, the guide rail mechanism is one of the core moving parts of the machine tool, directly supporting moving parts such as the worktable or slide saddle, and guiding them to perform precise and stable reciprocating motion along a predetermined trajectory. For example, a machine tool sliding guide rail mechanism proposed in patent application number 202121574328.6 includes a guide rail body, a slider body slidably connected to one side of the outer wall of the guide rail body, a top plate installed at the top of the slider body, and several fixing holes at the top of the top plate. The slider body has cavities on both sides near the fixing holes, and several bolts are threadedly connected inside the cavities. The cavities are respectively connected to a first base and a second base by bolts. A telescopic rod is connected to one side of the first base and the second base, and a pressure spring is sleeved on the outer wall of the telescopic rod. One end of the telescopic rod is connected to a bracket, and one end of the pressure spring is connected to the bracket. Bearings are embedded on both sides of the outer wall of the bracket, and a pressure roller is movably connected to the bracket through the bearings. One side of the outer wall of the pressure roller penetrates the cavity and fits against the guide rail body.

[0003] During machine tool processing, some of the generated debris will accumulate on both sides of the guide rail. When the slider moves on the guide rail, small debris will enter the gap between the slider and the guide rail. The debris will cause wear on the surface of the guide rail and the slider. Over time, the gap between the slider and the guide rail will increase, causing the slider to wobble and shift position during movement. Therefore, we have made improvements to this and proposed a sliding guide rail mechanism for machine tools. Utility Model Content

[0004] The main purpose of this utility model is to provide a sliding guide mechanism for machine tools, which can effectively solve the problem that during the machining process, some of the debris will accumulate on both sides of the guide rail. When the slider moves on the guide rail, small debris will enter the gap between the slider and the guide rail. The debris will cause wear on the surface of the guide rail and the slider. After long-term use, the gap between the slider and the guide rail will increase, causing the slider to wobble and shift position during movement.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A sliding guide mechanism for a machine tool includes a base plate, a plurality of fixing holes evenly distributed on the upper surface of the base plate, baffles installed on both sides of the upper surface of the base plate, a guide rail installed between two baffles, a slider slidably installed above the guide rail, a placement platform installed on the top of the slider, and cleaning mechanisms provided at both ends of the slider.

[0007] Preferably, the slider includes a housing, which is slidably mounted on a guide rail, the placement platform is mounted on the top of the housing, and mounting brackets are installed at both ends of the interior of the housing.

[0008] Preferably, one of the mounting brackets has a drive wheel rotatably mounted inside, the other mounting bracket has a driven wheel rotatably mounted inside, and a servo motor for controlling the rotation of the drive wheel is mounted on the top of one of the mounting brackets.

[0009] Preferably, guide protrusions are installed on both sides of the guide rail, and the surfaces of the driving wheel and the driven wheel are provided with first grooves that cooperate with the guide protrusions.

[0010] Preferably, the cleaning mechanism includes push plates, which are mounted on both ends of the housing and two are provided at each end. Each push plate has a cleaning ramp on one side.

[0011] Preferably, each of the push plates has a second groove inside that mates with the guide protrusion, and a scraper is installed on one end surface of each push plate, the scraper being attached to the outside of the guide protrusion.

[0012] Preferably, one of the push plates on the same side has a mounting groove on its top, and the other push plate on the same side has a mounting block on its top. One end of the mounting block is located inside the mounting groove, and the top of the push plate is also equipped with a fixing bolt for fixing the mounting block in position.

[0013] Preferably, each of the push plates has a buckle installed on one end surface, and the housing has slots on both ends surface that engage with the buckle.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] As the slider moves on the guide rail, the push plates on both sides push away the debris remaining on both sides of the guide rail. The outer side of the push plate is equipped with a cleaning ramp. During the pushing process, the debris is pushed away from the guide rail. The scraper moves with the push plate and can clean the debris on the guide protrusion surface during the movement, preventing debris from entering the interior during the slider's movement. This can effectively reduce the wear on the mating clearance surface between the slider and the guide rail and improve the service life of the slider. Attached Figure Description

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] like Figure 1 , Figure 3As shown, a sliding guide rail mechanism for a machine tool includes a base plate 1. Several fixing holes 2 are evenly distributed on the upper surface of the base plate 1. Baffles 3 are installed on both sides of the upper surface of the base plate 1. A guide rail 4 is installed between two baffles 3. A slider 5 is slidably installed above the guide rail 4. A placement platform 6 is installed on the top of the slider 5. Cleaning mechanisms 7 are provided at both ends of the slider 5.

[0027] like Figure 2 , Figure 4 As shown, the slider 5 includes a housing 501, which is slidably mounted on the guide rail 4. The placement platform 6 is mounted on the top of the housing 501. Mounting brackets 502 are mounted at both ends inside the housing 501. A drive wheel 503 is rotatably mounted inside one mounting bracket 502, and a driven wheel 505 is rotatably mounted inside the other mounting bracket 502. A servo motor 504 for controlling the rotation of the drive wheel 503 is mounted on the top of one mounting bracket 502. Guide protrusions 401 are mounted on both sides of the guide rail 4. The surfaces of the drive wheel 503 and the driven wheel 505 are provided with first grooves 506 that cooperate with the guide protrusions 401.

[0028] The driven wheel 505 has a first groove 506 on its surface that cooperates with the guide protrusion 401. When the driving wheel 503 rotates and controls the movement of the housing 501, the driven wheel 505 will also rotate as it moves, which can limit the movement trajectory of the housing 501, making the entire slider 5 more stable during movement and preventing positional deviation.

[0029] like Figures 5 to 8 As shown, the cleaning mechanism 7 includes push plates 701, which are installed on both ends of the housing 501, with two push plates 701 on each end. Each push plate 701 has a cleaning slope 702 on one side, and a second groove 7011 that mates with the guide protrusion 401 is provided inside each push plate 701. A scraper 703 is installed on one end of each push plate 701, and the scraper 703 fits against the outside of the guide protrusion 401. A mounting groove 704 is provided on the top of one of the push plates 701 on the same side, and a mounting block 705 is installed on the top of the other push plate 701 on the same side. One end of the mounting block 705 is located inside the mounting groove 704. A fixing bolt 706 for fixing the position of the mounting block 705 is also installed on the top of the push plate 701. A buckle 707 is installed on one end of each push plate 701, and a slot 5011 that mates with the buckle 707 is provided on both ends of the housing 501.

[0030] The mounting block 705 is fixed in the mounting groove 704 by fixing bolt 706, which allows the two push plates 701 on the same side to be combined together. The installation and disassembly operation is simple and easy to replace. The position of the push plate 701 at the end of the housing 501 can be limited by the cooperation between the buckle 707 and the slot 5011, which facilitates the installation. The second groove 7011 on the inner side of the push plate 701 fits with the guide protrusion 401, so that the push plate 701 has a better cleaning effect on debris during the movement.

[0031] The working principle of a sliding guide mechanism for machine tools:

[0032] The base plate 1 can be fixed in position through the fixing hole 2, thereby completing the fixation of the entire guide rail mechanism. Disassembly is convenient. The servo motor 504 drives the drive wheel 503 to rotate. The first groove 506 inside the drive wheel 503 cooperates with the guide protrusion 401. During the rotation of the drive wheel 503, it can drive the housing 501 to move, so that the slider 5 slides on the guide rail 4, and the placement platform 6 will move accordingly. When the slider 5 moves on the guide rail 4, the push plates 701 on both sides will push the debris remaining on both sides of the guide rail 4. The outer side of the push plate 701 is provided with a cleaning slope 702. When pushing, it will push the debris away from the guide rail 4. The scraper 703 will move with the push plate 701. During the movement, it can clean the debris on the surface of the guide protrusion 401, which can effectively prevent debris from entering the interior during the movement of the slider 5, effectively reduce the wear on the mating gap surface between the slider 5 and the guide rail 4, and improve the service life of the slider 5.

[0033] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
