[0031] The present invention will be further described in detail below with reference to the accompanying drawings.
[0032] Example:
[0033] Reference Figures 1-5 The present invention discloses a guide rail slider assembly for machine tools, comprising:
[0034] The self-cleaning guide rail 1 has several flow guide cavities inside, and the flow guide cavities are equipped with jet assembly 2.
[0035] The flow guide cavity includes a squeezing chamber 3 and an exhaust chamber 4. The squeezing chamber 3 is located inside the self-cleaning guide rail 1 and corresponds to the limiting grooves 11 on both sides of the self-cleaning guide rail 1. Both ends of the squeezing chamber 3 pass through the self-cleaning guide rail 1 and are connected to the limiting grooves 11. The exhaust chamber 4 is connected to the squeezing chamber 3, and the top of the exhaust chamber 4 passes through the top wall of the self-cleaning guide rail 1.
[0036] The detachable slider 5 is slidably mounted on the top of the self-cleaning guide rail 1. Two limiting plates 7 are detachably mounted on both sides of the detachable slider 5 via connecting components 6. The limiting plates 7 are inserted into the limiting groove 11. An adjusting component 8 is provided inside the detachable slider 5 to adjust the gap between the two limiting plates 7.
[0037] In this embodiment, when the detachable slider 5 slides at the top of the self-cleaning guide rail 1, as... Figure 5 As shown, the portion of the two side limiting plates 7 inserted into the limiting groove 11 will push the jet assembly 2 to compress the air inside the extrusion chamber 3, causing the air inside to be ejected through the exhaust chamber 4 and contact the bottom end of the detachable slider 5. At this time, the discharged air will wash the surface of the guide rail and the bottom end of the detachable slider 5, thereby achieving the effect of removing the turning chips from the top of the self-cleaning guide rail 1 and the bottom end of the detachable slider 5.
[0038] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 5 As shown, the jet assembly 2 includes:
[0039] A support spring 21 is provided inside the extrusion chamber 3. Sealing pistons 22 are fixedly provided at both ends of the support spring 21, and the sealing pistons 22 are slidably provided inside the extrusion chamber 3.
[0040] Each of the two sealed pistons 22 has a rotating ball 23 at one end, and a fixing rod 24 is provided in the middle of the support spring 21 to fix the support spring 21. When the support spring 21 is in the extended state, the two rotating balls 23 protrude out of the extrusion chamber 3.
[0041] In this embodiment, when the detachable slider 5 moves, the limiting plates 7 on both sides squeeze the rotating balls 23 on both sides. At this time, the rotating balls 23 on both sides will push the two sealing pistons 22 to move into the extrusion chamber 3 and compress the support spring 21. At this time, the air inside the extrusion chamber 3 will move upward and be discharged through the discharge chamber. The air is guided by the bottom end of the detachable slider 5 so that the air can wash the self-cleaning guide rail 1 and the detachable slider 5 to achieve the purpose of removing turning chips.
[0042] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the connection component 6 includes:
[0043] The sliding groove 61 is formed on the side wall of the detachable slider 5. A connecting block 62 is slidably arranged inside the sliding groove 61. The bottom end of the connecting block 62 is fixedly connected to the limiting plate 7. A screw hole 63 is formed inside the connecting block 62.
[0044] In this embodiment, the sliding groove 61 is used to position and install the connecting block 62, and the screw hole 63 is used to facilitate the adjustment component 8 to control the movement of the connecting block 62. The screw hole 63 is used to cooperate with the adjustment component 8 to achieve the effect of adjusting the sliding of the connecting block 62.
[0045] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the adjustment component 8 includes:
[0046] The rotating cavity 81 is located inside the detachable slider 5. A bidirectional screw 82 is rotatably installed inside the rotating cavity 81. The two ends of the bidirectional screw 82 are respectively inserted into the screw holes 63 inside the two connecting blocks 62. A control component for adjusting the bidirectional screw 82 is provided inside the rotating cavity 81.
[0047] In this embodiment, during use, the control component drives the bidirectional screw 82 to rotate. At the same time, the threads at both ends of the bidirectional screw 82 are in opposite directions. When the bidirectional screw 82 rotates, the screw threads on both sides can cooperate with the screw holes 63 to push the connecting blocks 62 on both sides to move relative to each other, thereby adjusting the movement of the connecting blocks 62 on both sides and allowing the two limiting plates to move relative to each other, so as to clamp or loosen the self-cleaning guide rail 1, so as to facilitate the connection or removal of the detachable slider 5 and the self-cleaning guide rail 1.
[0048] In a further preferred embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the control component includes:
[0049] The worm gear 83 is sleeved on the middle of the outer peripheral wall of the double-acting screw 82 and is fixedly connected to the double-acting screw 82;
[0050] A rotating hole 84 is formed at the top of the interior of the detachable slider 5 and extends through the rotating cavity 81. A control shaft 85 is provided inside the rotating hole 84, and a worm 86 that cooperates with the worm gear 83 is provided on the outer peripheral wall of the control shaft 85.
[0051] In this embodiment, the end of the control shaft 85 is provided with an adjustment hole, which can be a hexagonal hole, a flat hole, or a cross hole, so that the worker can manually adjust the rotation of the control shaft 85 by using a hexagonal wrench, a flat wrench, or a cross wrench. At this time, during the rotation of the control shaft, the worm gear 86 can drive the worm wheel 83 to rotate, and the worm wheel 83 is fixedly connected to the bidirectional screw 82, thereby driving the bidirectional screw 82 to rotate.
[0052] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the bottom end of the detachable slider 5 is provided with a ventilation groove 9 at a position corresponding to the exhaust chamber, and the depth of the ventilation groove 9 decreases linearly from the middle to both sides.
[0053] In this embodiment, since the position of the ventilation groove 9 corresponds to the position of the exhaust chamber 4, when air is discharged through the exhaust chamber 4, air enters the ventilation groove 9. Since the bottom end of the detachable slider 5 is in contact with the top wall of the self-cleaning guide rail 1, after the air enters the interior of the ventilation groove 9, it can only be discharged through both ends of the ventilation groove 9. Since the groove depth on both sides of the ventilation groove 9 gradually decreases, the air flow rate can be effectively increased, thereby achieving the purpose of improving the cleaning effect on the guide rail.
[0054] The implementation principle of the above embodiment is as follows: When the detachable slider 5 slides at the top of the self-cleaning guide rail 1, the portion of the two side limiting plates 7 inserted into the limiting groove 11 will push the rotating balls 23 on both sides, causing the two sealing pistons 22 to move into the squeezing chamber 3 and compress the support spring 21. At this time, the air inside the squeezing chamber 3 will move upward and be discharged through the discharge chamber, and the air will be guided by the bottom end of the detachable slider 5. The air can then be used to clean the self-cleaning guide rail 1 and the detachable slider 5.
[0055] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
