Description

Technical Field

[0001] This utility model belongs to the field of bottom-locking guide rail technology, specifically a novel bottom-locking guide rail. Background Technology

[0002] The bottom-locking guide rail is a type of linear guide rail. Linear guide rails are used in high-precision or high-speed linear reciprocating motion applications. The function of the linear guide rail is to support and guide moving parts to perform reciprocating linear motion in a given direction. Due to the different installation method compared to other installation methods, the performance is limited by the structural design, and the direction of force is restricted. Additional support is required to prevent the bottom-locking guide rail body from shifting on the surface of the table. During installation, a certain range of wobbling should be left, which can lead to the accumulation of metal shavings or coolant, potentially causing the rolling elements to jam.

[0003] Meanwhile, patent application number 202421862168.9 discloses a quick-release pneumatic rail lock, including a rail slider. The side wall of the rail slider has an installation notch. The installation notch contains a rail lock assembly. The rail lock assembly includes a drive cylinder fixed in the installation notch. A piston is movably installed in the drive cylinder. A telescopic support is fixedly installed on the piston. A spring is sleeved on the telescopic support inside the drive cylinder. A positioning base is fixedly installed at the end of the telescopic support. A friction plate is fixedly installed on the surface of the positioning base. A fixing mechanism is installed in the installation notch.

[0004] However, in implementing the relevant technology, it was found that the aforementioned quick-release pneumatic rail lock requires a long time to clean between the rail and the desktop, and also requires additional equipment for cleaning, increasing its own weight. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a novel bottom-locking guide rail, which combines cleaning with a tabletop support, collects dust and coolant between the bottom-locking guide rail body and the tabletop support, and reduces disassembly and assembly.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a novel bottom-locking guide rail, comprising a bottom-locking guide rail body and a sliding guide block sleeved on the surface of the bottom-locking guide rail body, wherein a bearing table is fixedly connected to the bottom end of the bottom-locking guide rail body, and anti-tilting blocks are fixedly connected to the surface of the bearing table respectively.

[0007] The surface of the support tabletop has an annular groove located between the locking guide rail body and the anti-tilting block. A fixing block is fixedly connected to the surface of the support tabletop. A rotating handle passes through one end of the fixing block. The rotating handle passes through the surface of the fixing block and has a central shaft sleeved on its outer side. A water-absorbing cotton is sleeved on the surface of the central shaft. The water-absorbing cotton rotates inside the annular groove. A liquid inlet groove is provided on the surface of the support tabletop, and the liquid inlet groove is located on both sides of the annular groove. A vertical groove is provided at the position of the annular groove.

[0008] Preferably, a limiting block is fixedly connected inside the vertical groove, a fixing plate is fixedly connected inside the limiting block, a connecting rod is slidably connected inside the fixing plate, a clamping plate is fixedly connected to the end away from the connecting rod, a spring is sleeved on the surface of the connecting rod, and the spring is located between the fixing plate and the clamping plate.

[0009] Preferably, the anti-tilting block has a square groove with an opening facing downwards towards the surface of the locking guide rail body. A shock-absorbing block is fixedly connected to the inner wall of the square groove of the anti-tilting block. A movable plate is pressed against the surface of the shock-absorbing block. A connecting shaft is rotatably connected inside the anti-tilting block. The connecting shaft passes through the anti-tilting block and the movable plate in sequence. The movable plate rotates inside the anti-tilting block. Several sets of buoyancy balls are fixedly connected to the surface of the movable plate. Air tubes are connected between the several sets of buoyancy balls.

[0010] Preferably, the absorbent cotton is pressed against the surface of the abutment plate, and a liquid dispensing hole is provided in the annular groove at the bottom end of the abutment plate.

[0011] Preferably, a cover plate is attached to the top of the annular groove, the cover plate being used to seal the annular groove.

[0012] Preferably, the absorbent cotton is provided in two sets.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model involves creating an annular groove between the locking guide rail body and the supporting tabletop to hold absorbent cotton. The absorbent cotton collects the coolant used for cooling when the locking guide rail body slides on the surface of the sliding guide block. The coolant flows into the annular groove through the inlet groove, and the absorbent cotton absorbs the coolant. When one side of the absorbent cotton is wet, rotating the handle rotates the originally wet absorbent cotton to the extrusion area, while the absorbent cotton in the original extrusion area rotates to the collection area for continued collection. In conjunction with the extrusion device set in the vertical groove inside the annular groove, the absorbent cotton scrapes the absorbent cotton containing coolant, discharging the coolant inside the absorbent cotton, thus completing the collection of coolant from the surface of the supporting tabletop, keeping the surface dry, and reducing the resistance when the sliding guide block slides on the surface of the locking guide rail body.

[0015] 2. This utility model adds a device at the top of the support table to limit the surface of the locking guide rail body, preventing the locking guide rail body from shaking on the support table surface. When the locking guide rail body shakes on the support table surface, the locking guide rail body squeezes the buoyancy ball for initial buffering, and the movable plate pushes it to form an offset inside the anti-tilting block. The shock-absorbing block at one end of the movable plate is used to buffer the tilted movable plate and play a pressing role, preventing the locking guide rail body from tilting too much on the support table surface.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 6 As shown, this utility model provides a novel bottom-locking guide rail, including a bottom-locking guide rail body 1 and a sliding guide block 2 that slides on the surface of the bottom-locking guide rail body 1. A support table 3 is fixedly connected to the bottom end of the bottom-locking guide rail body 1, and anti-tilting blocks 4 are fixedly connected to the surface of the support table 3 respectively.

[0028] An annular groove 31 is formed on the surface of the support tabletop 3. The annular groove 31 is located between the locking guide rail body 1 and the anti-tilting block 4. A fixing block 32 is fixedly connected to the surface of the support tabletop 3. A rotating handle 33 passes through one end of the fixing block 32. The rotating handle 33 passes through the surface of the fixing block 32 and a central shaft 34 is sleeved on its outer side. A water-absorbing cotton 35 is sleeved on the surface of the central shaft 34. The water-absorbing cotton 35 can be used to absorb the coolant flowing into the support tabletop 3 through the liquid inlet groove 36, thus preventing it from being used by the locking guide rail body 1 and the sliding guide block. The coolant used for cooling between the two surfaces flows between the locking guide rail body 1 and the supporting table 3, resulting in reduced accuracy. The absorbent cotton 35 rotates inside the annular groove 31. When one side of the absorbent cotton 35 is wet, it rotates to the other side and is then used for collection. During the rotation of the absorbent cotton 35 inside the annular groove 31, a squeezing device is added inside the vertical groove 37 at the position of the annular groove 31 to squeeze out the coolant on the surface of the absorbent cotton 35, so that the absorbent cotton 35 does not need to be pulled out for drying or replaced.

[0029] Specifically, a limiting block 5 is fixedly connected inside the vertical groove 37, and a fixing plate 51 is fixedly connected inside the limiting block 5. The pressing plate 54 drives the connecting rod 52 to slide towards the fixing plate 51. During the sliding process, the spring 53 on the surface of the connecting rod 52 is compressed and deformed. As the absorbent cotton 35 rotates continuously at the position of the pressing plate 54, the moisture in the absorbent cotton 35 decreases continuously. The spring 53 pushes the pressing plate 54 to keep it in contact with the absorbent cotton 35, and the pressing plate 54 continuously squeezes out the saturated coolant inside the absorbent cotton 35.

[0030] Furthermore, the anti-tilting block 4 has a square groove with an opening facing downwards towards the surface of the locking guide rail body 1. A shock-absorbing block 45 is fixedly connected to the inner wall of the square groove of the anti-tilting block 4. A movable plate 43 is pressed against the surface of the shock-absorbing block 45. A connecting shaft 44 is rotatably connected inside the anti-tilting block 4. The connecting shaft 44 passes through the anti-tilting block 4 and the movable plate 43 in sequence. The connecting shaft 44 is used to support the movable plate 43. The movable plate 43 rotates inside the anti-tilting block 4 to adapt to the rotation of the movable plate 43 in different directions of the anti-tilting block 4 for support. Several sets of buoyancy balls 41 are fixedly connected to the surface of the movable plate 43. The buoyancy balls 41 contain gas. When compressed by external force, the external gas will be transferred from the buoyancy ball 41 under force to the other buoyancy balls 41 through the air pipe 42. The buoyancy balls 41 are used to initially buffer the surface of the locking guide rail body 1 and reduce the shaking of the locking guide rail body 1 on the surface of the supporting table 3.

[0031] Furthermore, the absorbent cotton 35 presses against the surface of the pressing plate 54, and the water squeezed out by the pressing plate 54 is discharged from the liquid distribution hole 38 opened at the position of the annular groove 31.

[0032] It is worth noting that a cover plate 39 is attached to the top of the annular groove 31, and the cover plate 39 is used to seal the annular groove 31.

[0033] It is worth noting that there are two sets of absorbent cotton 35, which are used to collect the coolant on both sides of the surface of the locking guide rail body 1, keep the gap between the locking guide rail body 1 and the supporting table 3 dry, and prevent the locking guide rail body 1 from shifting on the surface of the supporting table 3, which would cause the locking guide rail body 1 to bend.

[0034] The locking guide rail body 1, sliding guide block 2, and supporting tabletop 3 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, back, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0035] Working principle:

[0036] The sliding guide block 2 slides on the surface of the locking guide rail body 1. During the sliding process, the locking guide rail body 1 needs to withstand the shaking force from the sliding guide block 2. The sliding guide block 2 shakes slightly on the surface of the table 3. During the shaking, the sliding guide block 2 squeezes the buoyancy ball 41. The gas inside the squeezed buoyancy ball 41 is inflated to the other buoyancy balls 41 through the air pipe 42. The buoyancy ball 41 is used to initially buffer the resistance and shaking force from the air pipe 42. Then, the buoyancy ball 41 squeezes the movable plate 43 to rotate inside the anti-tilting block 4. During the rotation of the movable plate 43, one side of the movable plate 43 will squeeze the shock absorber 45. The shock absorber 45 buffers the inner wall of the anti-tilting block 4, reducing the shaking of the movable plate 43 inside the anti-tilting block 4.

[0037] When the sliding guide block 2 is used on the surface of the locking guide rail body 1 for a long time, due to the long-term friction between the two sets, coolant needs to be sprayed. The coolant will flow out from the gap between the locking guide rail body 1 and the support table 3. When the coolant flows from the inlet groove 36 to the annular groove 31 on the surface of the support table 3, the absorbent cotton 35 inside the annular groove 31 is used to absorb the coolant. When the absorbent cotton 35 is observed to be saturated, the rotating handle 33 is held. The rotating handle 33 drives the absorbent cotton 35 on the surface of the central shaft 34 to rotate in the annular groove 31. During the rotation, the surface of the absorbent cotton 35 and the surface of the abutment plate 54 are in contact. When contact occurs, the pressing plate 54 squeezes the absorbent cotton 35. After being pressed by the absorbent cotton 35, the pressing plate 54 drives the connecting rod 52 to slide towards the fixed plate 51. During the sliding process, the spring 53 on the surface of the connecting rod 52 is squeezed and deformed. As the absorbent cotton 35 rotates continuously at the position of the pressing plate 54, the moisture in the absorbent cotton 35 decreases continuously. The spring 53 pushes the pressing plate 54 to keep it in contact with the absorbent cotton 35, and the pressing plate 54 continuously squeezes out the saturated coolant inside the absorbent cotton 35 and discharges it from the liquid distribution hole 38 inside the annular groove 31, thus completing the collection of coolant.
