Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a dustproof device for a machine tool guide rail. Background Art

[0002] A guide rail is usually arranged on the surface of a machine tool to realize the displacement of the machining mechanism of the machine tool. After searching, the Chinese patent authorization number CN111571295B discloses a dust prevention device for a plane guide rail of a machine tool, which is convenient for dust prevention and cleaning of the guide rail, avoids dust accumulation in the guide rail, improves the moving accuracy of the tool holder, and collects dust to avoid environmental pollution. However, when the slider of the device moves in the opposite direction, the gear rotates clockwise, and the gear drives the round rod to rotate clockwise. Since the bevel block and the bevel groove are unidirectionally connected, the round rod will not drive the disc to rotate, and the suction fan will not rotate. In this way, the slider moves back and forth, and the dust inside the guide rail can be cleaned, which can play a dust prevention role and avoid pollution. However, the surface of the guide rail is usually regularly coated with lubricating oil for maintenance, which causes dust to adhere to the lubricating oil, and it is difficult to absorb and clean the dust adhered to the surface of the lubricating oil by the suction fan. Utility Model Content

[0003] In view of the deficiencies of the prior art, the utility model provides a dustproof device for a machine tool guide rail, which solves the problem in the background art that the existing dustproof device is difficult to absorb and clean the dust attached to the surface of the lubricating oil through an air suction fan.

[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a dustproof device for a machine tool guide rail, comprising a guide rail body, a slider, a sealing cover, a positioning block and an oil filling port, the outside of the guide rail body being slidably connected to the bottom of the slider, sealing covers are provided on both sides of the slider, one end of the sealing cover is connected to the slider by bolts, and the other end of the sealing cover is connected to a connecting piece by bolts, one side of the connecting piece is glued to one end of the dust cover, and the other end of the dust cover is glued to the side of one end of the positioning block, and the positioning blocks are distributed at both ends of the guide rail body.

[0005] Preferably, the interior of the two sides of the positioning block is threadedly connected to the locking screw, the surface of one end of the locking screw is made of rubber material, and one end of the locking screw is against the surface of the guide rail body. By loosening the locking screw, the positioning block can slide, and then the position of the positioning block is adjusted, which is conducive to adjusting the telescopic length of the dust cover according to the length of the guide rail.

[0006] Preferably, the interior of the slider is a hollow structure, and the interior of the slider is connected to the oil filling port. One end of the top of the oil filling port is threadedly connected to the plug. The inner side of the bottom of the slider is provided with a plurality of oil outlet holes in a straight line and at equal intervals, which are connected to the interior. The lubricating oil inside the slider will seep out through the holes and grooves at the bottom, thereby enabling lubrication between the lubricating oil and the slider. Excess lubricating oil can be scraped off by the sealing ring and the scraper during the sliding process of the slider, thereby helping to avoid excessive lubricating oil on the surface of the guide rail.

[0007] Preferably, a scraper is embedded inside the sealing cover, a groove is provided at the bottom of the scraper, and the bottom of the scraper is tightly fitted with the surface of the guide rail body. The surface of the scraper is sprayed with a rubber coating, and the slider will drive the slide plate to scrape during the movement of the slider, which is beneficial for the scraper to clean the dust and lubricating oil on the surface of the guide rail.

[0008] Preferably, two dust covers are provided, the bottoms of the two dust covers are engaged with the two sides of the guide rail body, and the surface of the dust covers is multi-bend, and the dust covers are made of flexible rubber material, which is conducive to the dust covers being able to retract and avoid affecting the sliding of the slider.

[0009] Preferably, the inner wall of the bottom of the slider is tightly fitted with the surface of the guide rail body, and sealing rings are embedded at both ends of the bottom of the slider. The sealing rings on both sides of the bottom of the slider are helpful to reduce the leakage of lubricating oil to the outside of the slider.

[0010] The utility model provides a dust prevention device for a machine tool guide rail, which has the following beneficial effects:

[0011] (1) A dustproof device for a machine tool guide rail. When the dustproof device is in use, positioning blocks are fixed at both ends of the guide rail. When the slider slides, the dust cover will be extended and retracted. By arranging the dust cover on the outside of the guide rail, dust can be isolated outside the dust cover, which helps to prevent external dust from adhering to the lubricating oil on the surface of the guide rail, thereby achieving a dustproof effect fundamentally.

[0012] (2) The dust prevention device of the machine tool guide rail fills the lubricating oil into the slider through the oil filling port, so that the lubricating oil can be discharged from the hole groove at the bottom of the slider, thereby enabling lubrication between the lubricating oil and the slider. Excess lubricating oil can be scraped off by the sealing ring and the scraper during the sliding process of the slider, thereby helping to avoid excessive lubricating oil on the surface of the guide rail, which makes it easy for dust to adhere.

[0013] This solves the problem that the existing dust-proof device is difficult to absorb and clean the dust attached to the surface of the lubricating oil through the suction fan. BRIEF DESCRIPTION OF THE DRAWINGS
