Description

Technical Field

[0001] The invention relates to the technical field of slides, in particular to a ball screw slide with a dust removal structure. Background Art

[0002] A ball screw is a product that converts rotary motion into linear motion. It is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or to convert torque into axial repetitive force. It has the characteristics of high precision, reversibility and high efficiency. Different from ordinary screw transmission mechanisms, ball screws are driven by the meshing of balls and screws. Ball screw slides can be used in various industries such as inkjet printing, marking, laser machines, plotters, engraving machines, printing machines, etc.

[0003] When the existing ball screw slide is in use, the dust contained in the air will adhere to the surface of the screw, which may cause the slide to lose accuracy during movement due to the dust. Although the ball screw slide can be made into a fully enclosed type, it can only prevent most of the dust from entering. A small amount of dust will still enter and adhere to the surface of the screw. In order to make the slide move more smoothly, lubricating oil is usually applied to the surface of the slide. The lubricating oil has a certain viscosity, so the dust is tightly attached to the surface of the screw due to the viscosity of the lubricating oil and is difficult to clean.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1-Figure 10In an embodiment of the present invention, a ball screw slide with a dust removal structure includes a ball screw slide body 1, two symmetrical silicone dust covers 2, and a dust removal mechanism 3. The outer wall of the screw in the ball screw slide body 1 is penetrated by a slider 11 that is screwed together. The top surface of the slider 11 is fixedly connected with a mounting plate 12. The two symmetrical silicone dust covers 2 are fixedly connected to both sides of the slider 11, and one end of the silicone dust cover 2 is fixedly connected to the frame of the ball screw slide body 1 to prevent most of the dust from entering the interior of the ball screw slide body 1. The dust removal mechanism 3 is arranged between the slider 11 and the mounting plate 12 to clean the outer wall of the screw in the ball screw slide body 1. The dust removal mechanism 3 includes an oil storage tank 31 fixedly connected to the top surface of the slider 11, and the two opposite side surfaces of the slider 11 are detachably connected with a cleaning component 32 for cleaning the dust on the outer wall of the screw. The cleaning component 32 is sleeved on the outside of the screw, and the two opposite side surfaces of the oil storage tank 31 are provided with an oil pressure component 33 for adding lubricating oil in the oil storage tank 31 to press the lubricating oil into the cleaning component 32 at the corresponding position. The top surface of the oil storage tank 31 is fixedly connected with a filter component 34, and the interior of the filter component 34 is connected to the interior of the oil storage tank 31 through a pipeline. One side of the oil storage tank 31 is provided with a recovery component 35 for drawing excess lubricating oil at the bottom of the two cleaning components 32 into the filter component 34.

[0038] Specifically, first, the lubricating oil is poured into the oil storage tank 31 through a syringe, and then the screw is driven by an external motor to rotate and drive the slider 11 to move. The moving slider 11 can compress the silicone dust cover 2 in its moving direction, and stretch the other silicone dust cover 2, thereby preventing most of the dust from entering the interior of the frame. While the slider 11 is moving, the oil pressure component 33 in the forward direction of the slider 11 can press the lubricating oil in the oil storage tank 31 into the cleaning component 32 at the corresponding position, while the other oil pressure component 33 does not work at this time. The lubricating oil pressed into the cleaning component 32 can drip onto the outer wall of the screw. If there is dust attached to the outer wall of the screw, the dripping lubricating oil can absorb the dust and drop it on the outer wall of the screw under the action of its own gravity. The bottom of the cleaning component 32 at the corresponding position, and the rotation of the screw generates centrifugal force, so that most of the lubricating oil dripping on the outer wall of the screw is thrown out and flows into the bottom of the cleaning component 32 at the corresponding position (in layman's terms, the outer wall of the screw is cleaned with the lubricating oil), and the small amount of lubricating oil remaining on the screw can lubricate the ball in the slider 11 to reduce the friction between the ball and the screw. Since the slider 11 will also drive the recovery component 35 to work when it moves, and the movement of the slider 11 drives the two cleaning components 32 to move, the lubricating oil that is not completely separated from the surface of the screw will fall on the bottom of the other cleaning component 32. At the same time, the recovery component 35 can work to draw the lubricating oil concentrated at the bottom of the two cleaning components 32 into the filter component 34 In the embodiment, the dust in the recovered lubricating oil can be separated from the lubricating oil by the filtering component 34 (the filtering component is a prior art and will not be described in detail here), and the filtered lubricating oil flows into the oil storage tank 31 again under the action of its own gravity, thereby realizing the recycling of the lubricating oil and reducing the waste of the lubricating oil. When the slider 11 moves in the opposite direction, another oil pressing component 33 presses the lubricating oil in the oil storage tank 31 into the cleaning component 32 at the corresponding position, and the originally working oil pressing component 33 is in a stopped state at this time (because this oil pressing component 33 is located at the reverse position of the movement of the slider 11, if the oil pressing component 33 here applies the lubricating oil to the outer wall of the screw, as the slider 11 moves, too much lubricating oil will remain on the surface of the screw and will drip onto the ball screw slide The lubricating oil is wasted on the frame of the main body 1, and the oil pressing component 33 at the forward direction of the slider 11 works. Although there will be residual lubricating oil on the surface of the screw, part of the residual lubricating oil will enter the ball in the slider 11, and part of it will fall into the cleaning component 32 at the reverse direction of the movement of the slider 11. At this time, the outer wall of the screw at the reverse direction of the movement of the slider 11 is in a wet state, but there is not too much lubricating oil, so the waste of lubricating oil can be avoided). The device presses the lubricating oil in the oil storage tank 31 into the cleaning component 32 at the corresponding position through the oil pressing component 33, so that the lubricating oil drips on the surface of the screw, and then absorbs the dust on the surface of the screw and falls to the bottom of the cleaning component 32 under the action of its own gravity and the centrifugal force generated by the rotation of the screw.Thus, dust cleaning treatment is carried out on the surface of the screw, so that the service life of the ball screw slide body 1 can be extended, the accuracy can be ensured, and through the reciprocating switching of the two oil pressing components 33, the oil pressing component 33 at the reverse movement position of the slider 11 can be avoided from working, so that excessive lubricating oil remaining on the outer wall of the screw at the reverse movement position of the slider 11 can be prevented from being thrown out, and thus the phenomenon of lubricating oil waste can be avoided.

[0039] Embodiment 1

[0040] As Figure 5 and Figure 7 shown, in this embodiment, the cleaning component 32 includes two symmetric fixing plates 321 detachably connected to the slider 11. One side surface of the fixing plate 321 is fixedly connected with a sleeve 322. A plurality of U-shaped clamping blocks 323 are fixedly connected to the inner wall of the sleeve 322 at equal intervals. A sponge 324 is detachably connected inside the U-shaped clamping block 323. A diversion pipe penetrating and fixing with the corresponding position of the sleeve 322 is fixedly penetrated on the inner side surface of the U-shaped clamping block 323. A tee pipe 325 is fixedly connected to the outer wall of the diversion pipe. A connecting pipe 326 is fixedly connected between the plurality of tee pipes 325 at the same sleeve 322. Both ends of the connecting pipe 326 are fixedly connected with connectors 327. The two connectors 327 at the relative positions are inserted into each other. Sealing plates 328 are fixedly connected to both ends of the inner wall of the sleeve 322. The fixing plate 321, the sleeve 322 and the sealing plate 328 are all semi-circular structures. Sealing gaskets are fixedly connected to both ends of the sealing plate 328 and the sleeve 322.

[0041] In this embodiment, when the oil pressing component 33 presses the lubricating oil in the oil storage tank 31 into the plurality of sponges 324, the sponges 324 absorb the lubricating oil and quickly reach the saturated state. At this time, the oil pressing component 33 continues to work. At this time, the sponges 324 no longer absorb the lubricating oil, and the excess lubricating oil drips from the upper sponges 324 into the grooves on the surface of the screw, so that the dust in the grooves on the screw surface is adsorbed by the dripping lubricating oil, and most of the dust on the screw surface is cleaned by the plurality of sponges 324. Moreover, when the sponges 324 reach saturation, the lubricating oil in the sponges 324 will be smeared on the outside of the screw, and then added with the dripping lubricating oil, so that there is more and more lubricating oil on the screw. At this time, the lubricating oil on the screw falls to the bottom of the sleeve 322 under the action of its own gravity and the centrifugal force generated by the rotation of the screw, and then the recycling component 35 pumps the lubricating oil at the bottom of the sleeve 322 into the filtering component 34. When the sponges 324 need to be replaced, by separating the two adjacent connectors 327 and then detaching the fixing plate 321 from the slider 11, at this time, the sleeve 322 can be taken off from the outside of the screw, and then the old sponges 324 are taken out from the U-shaped clamping blocks 323 at the corresponding positions and new sponges 324 are replaced, and then the fixing plate 321 is installed on the slider 11, and the two adjacent connectors 327 are inserted.

[0042] Embodiment 2

[0043] like Figure 8 As shown, in this embodiment, two opposite side surfaces of the oil storage tank 31 are fixedly connected with a fixed block 311, and the outer wall of one of the connecting pipes 326 located on the same side of the slider 11 is fixedly connected with a three-way pipe 4, and the oil pressure assembly 33 includes a sleeve 331 that penetrates and is fixed to the fixed block 311 at the corresponding position, and a piston 1 is slidably sleeved inside the sleeve 331, and an oil outlet pipe 332 that is fixedly connected to the three-way pipe 4 at the corresponding position is penetrated and fixed on the inner bottom surface of the sleeve 331, and an oil inlet pipe 333 that is fixedly connected to the inner bottom of the oil storage tank 31 is penetrated and fixed on the inner bottom surface of the sleeve 331, and a one-way valve 1 is fixedly connected to the outer walls of the oil inlet pipe 333 and the oil outlet pipe 332, and the bottom surface of the mounting plate 12 is fixedly connected with two symmetrical fixing seats 121, and the top of the piston 1 is fixedly connected to the top of the sleeve 331 at the corresponding position. A push rod 1 that slides through one end thereof, a pressure plate 334 is fixedly connected to the top of the push rod 1, a spring 335 is fixedly connected between the pressure plate 334 and the sleeve 331, a cam 336 that contacts the pressure plate 334 is rotatably connected to the interior of the fixed seat 121 through a rotating shaft, two toothed belts 13 are fixedly connected to both ends of the frame of the ball screw slide body 1, one end of the rotating shaft 1 passes through the fixed seat 121 at the corresponding position and is fixedly connected to a one-way bearing, a synchronous wheel 337 that meshes with the toothed belt 13 at the corresponding position is fixedly connected to the outer wall of the one-way bearing, a fixed seat 2 122 is fixedly connected to the bottom surface of the mounting plate 12 and is located between the two fixed seats 121, an auxiliary wheel 123 that abuts against the toothed belt 13 at the corresponding position is rotatably connected to the interior of the fixed seat 2 122, and the auxiliary wheel 123 is located below the two synchronous wheels 137.

[0044] In this embodiment, since the synchronous wheel 337 is meshed with the toothed belt 13 at the corresponding position, when the slider 11 moves forward, the synchronous wheel 337 in the forward direction rotates under the action of the toothed belt 13, and the rotating synchronous wheel 337 can make the cam 336 at the corresponding position rotate, so that the piston 1 at the corresponding position can reciprocate inside the sleeve 331 at the corresponding position under the action of the spring 335 and the rotating cam 336, and then under the action of the two one-way valves 1 at the corresponding position, the lubricating oil in the oil storage tank 31 can be pressed into the multiple sponges 324 at the corresponding position, so that the screw can be cleaned and lubricated. At this time, the cam 336 at the reverse direction of the movement of the slider 11 will not rotate under the action of the one-way bearing at the corresponding position. Even if the cam 336 rotates, it will not move due to the blocking action of the spring 335 at the corresponding position. Therefore, the piston 1 at the reverse direction of the movement of the slider 11 cannot press the lubricating oil in the oil storage tank 31 into the multiple sponges 324 at the corresponding position.

[0045] Embodiment 3

[0046] like Fig. 9 and Fig.10 As shown, in this embodiment, one end surface of the oil storage tank 31 is fixedly connected to a fixed block 2 312, and the recovery component 35 includes two symmetrical oil outlet pipes 2 351 that pass through and are fixed to the bottom of the casing 322 at the corresponding positions, a three-way pipe 2 352 is fixedly connected between the two oil outlet pipes 2 351 at the opposite positions, one end of the three-way pipe 2 352 is fixedly connected to an oil delivery pipe 353, and the outer wall of the oil delivery pipe 353 is fixedly connected to a three-way pipe 354 that is connected to the inside of the oil delivery pipe 353, and a sleeve 2 355 is fixedly passed through and fixed on the top surface of the fixed block 2 312, and a piston 2 is slidably sleeved inside the sleeve 2 355, and a piston 2 is fixedly passed through and fixed to the inner bottom surface of the sleeve 2 355. The connecting pipe one and the connecting pipe two that are fixedly penetrated and fixed to the inside of the filter assembly 34 are penetrated through the inner bottom surface of the sleeve two 355, the outer walls of the connecting pipe one and the connecting pipe two are fixedly connected with a one-way valve two, the bottom surface of the mounting plate 12 is fixedly connected with a fixing seat three 124, the top surface of the piston two is fixedly connected with a push rod two that slides through the top end of the sleeve two 355, the top end of the push rod two is fixedly connected with a pressure plate two 356, a spring two 357 is fixedly connected between the pressure plate two 356 and the sleeve two 355, the interior of the fixing seat three 124 is rotatably connected with a cam two 358 that is abutted against the pressure plate two 356 through a rotating shaft two, and one end of the rotating shaft two is fixedly connected with a synchronous wheel two 359 that meshes with the toothed belt 13 at the corresponding position.

[0047] In this embodiment, since the synchronous wheel 359 is meshed with the toothed belt 13 at the corresponding position, the moving slider 11 can make the synchronous wheel 359 rotate under the action of the toothed belt 13 at the corresponding position, and the rotating synchronous wheel 359 can make the cam 358 rotate, so that the piston 2 can reciprocate inside the sleeve 355 under the action of the spring 357 at the corresponding position and the rotating cam 358, so that the lubricating oil accumulated at the bottom of the sleeve 322 can be drawn into the filter assembly 34, and the lubricating oil can be recovered to prevent the lubricating oil at the bottom of the sleeve 322 from accumulating too much and overflowing, thereby realizing the recycling of the lubricating oil and reducing the waste of the lubricating oil.
