Description
本發明係為一種線性傳動元件,尤指一種具定位結構刮刷器之滾珠螺桿。 The invention relates to a linear transmission component, in particular to a ball screw with a positioning structure wiper.
按,精密機械、儀器中常使用一螺桿的轉動帶動一螺帽的移動,該螺帽上並提供一工作檯的設置,以此利用螺桿達到工作檯的精確控制,而螺帽於螺桿上移動時,為了增加移動的順暢、增加附載與減少磨擦力,均會於螺帽及螺桿間的相對螺紋槽設置滾珠,而螺帽於螺桿上,同時間僅一小段的接觸,多數其餘的螺桿段,均是暴露於外部空間中,而空間內佈滿了粉塵與各種異物,尤其多數的加工場所,環境更是惡劣,還有許多切削屑與加工油水的噴濺,該螺帽與該螺桿間並非密閉,因均為金屬構件,因此具有一間隙的存在,當這些粉塵、異物與切削屑落在螺桿表面時,會附著於螺桿表面,尤其含有油水時,該些附著物的附著累積更是驚人,且隨著螺桿的轉動與螺帽的移動,該些附著物並會由間隙進入螺桿與螺帽間到達滾珠處,進而會干涉滾珠的滾動與滾珠的磨耗,最終會影響該滾珠螺桿的壽命與精度,因此如何消除該間隙的存在,防止附著物進入滾珠螺桿內,便有許多結構的 設計因應而生,其中最常見的結構即係圖一的設計,係一螺桿(1)上設一螺帽(2),該螺桿(1)與該螺帽(2)間並各設有一螺紋槽(11、21),複數滾珠(4)係設於該螺紋槽(11、21)中循環滾動,且該螺帽(2)的端部內徑處設有一容置槽(22),以該容置槽(22)提供一刮刷器(3)的設置,該容置槽(22)的周緣設置複數貫穿螺孔(23),以該貫穿螺孔(23)提供該螺絲(5)鎖設,而該螺絲(5)係抵觸於該刮刷器(3)外緣,該刮刷器(3)係設於該容置槽(22)內,且內周緣設有配合該螺桿(1)螺紋槽(11)形狀的刮刷部(31),該刮刷部(31)並配合該螺紋槽(11)以幾乎貼合的方式設置,使該螺帽(2)及該刮刷器(3)於螺桿(1)上移動時,以該刮刷部(31)將該螺桿(1)上的附著物刮除,俾避免進入該螺帽(2)內。 According to the precision machinery and equipment, the rotation of a screw is often used to drive the movement of a nut. The nut is provided with a table setting, so that the screw can be used to achieve precise control of the table, and the nut moves on the screw. In order to increase the smoothness of the movement, increase the load and reduce the friction force, the balls are arranged on the opposite thread grooves between the nut and the screw, and the nut is on the screw with only a short contact at the same time, and most of the remaining screw segments, They are all exposed to the external space, and the space is covered with dust and various foreign objects. Especially in most processing places, the environment is even worse. There are also many sprinkles of cutting chips and processing oil. The nut is not between the screw and the screw. Sealed, because they are all metal members, so there is a gap. When these dust, foreign matter and cutting chips fall on the surface of the screw, they will adhere to the surface of the screw. Especially when oil and water are contained, the accumulation of these deposits is even more amazing. And with the rotation of the screw and the movement of the nut, the attachments will enter the ball between the screw and the nut through the gap, thereby interfering with the rolling of the ball and Beads wear, and eventually affect the accuracy of the life of the ball screw, so how to eliminate the presence of the gap, to prevent the deposit into the ball screw, there are many structures The design is the same, the most common structure is the design of Figure 1. A screw (1) is provided with a nut (2), and a screw is arranged between the screw (1) and the nut (2). a groove (11, 21), a plurality of balls (4) are cyclically rolled in the thread groove (11, 21), and a receiving groove (22) is provided at an inner diameter of the end of the nut (2), The accommodating groove (22) provides a setting of a squeegee (3), and the periphery of the accommodating groove (22) is provided with a plurality of through-holes (23), and the screw (5) is provided with the through-hole (23) The screw (5) is in contact with the outer edge of the wiper (3), the wiper (3) is disposed in the receiving groove (22), and the inner circumference is provided with the screw (1) a wiping portion (31) in the shape of a thread groove (11), the wiping portion (31) is disposed in an almost fitting manner in cooperation with the thread groove (11), so that the nut (2) and the wiper (3) When moving on the screw (1), the attachment on the screw (1) is scraped off by the wiping portion (31) to prevent entry into the nut (2).
前述習知結構使用具有下述的問題:正常的刮刷器(3)之刮刷部(31)與螺桿(1)之螺紋槽(11)的配合,其之間應具有間隙,因為於刮刷部(31)相對該螺紋槽(11)旋轉時,該刮刷部(31)才不會與該螺紋槽(11)產生摩擦,而增加該滾珠螺桿運行的阻力(如圖一所示,該刮刷部(31)與螺紋槽(11)係產生干涉),但因為該刮刷器(3)組裝時係由人工將刮刷器(3)旋入螺桿(1)的螺紋 槽(11),而後再容置於該螺帽(2)之容置槽(22),當刮刷器(3)進入該容置槽(22)後,裝配人員並無法得知刮刷部(31)是否與該螺紋槽(11)保持一間隙,因為刮刷部(31)與螺紋槽(11)之間的間隙以肉眼是看不到的,必須藉由量測滾珠螺桿運行的數據才能得知該刮刷部(31)是否與螺紋槽(11)干涉,故於確認過程中相當費時,如此,會使得裝配時間延長許多,且因為是藉由人工來調整刮刷部(31)與螺紋槽(11)的間隙,所以每一個人的調整結果一定無法一致,故也造成每一支滾珠螺桿的品質不一,相對也提高了客戶抱怨的次數,是以,習知的刮刷器結構設計仍有改良精進之必要。 The above conventional structure uses the problem that the wiping portion (31) of the normal wiper (3) and the screw groove (11) of the screw (1) are fitted with a gap therebetween because of the scraping When the brush portion (31) rotates relative to the thread groove (11), the wiping portion (31) does not rub against the thread groove (11), and the resistance of the ball screw operation is increased (as shown in FIG. The wiping portion (31) interferes with the thread groove (11), but because the wiper (3) is assembled, the squeegee (3) is manually screwed into the thread of the screw (1). The groove (11) is then placed in the receiving groove (22) of the nut (2). When the wiper (3) enters the receiving groove (22), the assembler cannot know the wiping portion. (31) Whether a gap is maintained with the thread groove (11) because the gap between the wiper portion (31) and the thread groove (11) is invisible to the naked eye, and the data of the ball screw operation must be measured. It can be known whether the wiping portion (31) interferes with the thread groove (11), so it is quite time consuming in the confirmation process, so that the assembly time is prolonged a lot, and because the wiping portion (31) is manually adjusted. The gap with the thread groove (11), so the adjustment result of each person must not be the same, which also causes the quality of each ball screw to be different, which also increases the number of customer complaints. Therefore, the conventional wiper Structural design is still necessary for improved improvement.
