Description

線性滑軌及其滑塊組接結構 Linear slide rail and its sliding block assembly structure

本發明係有關於線性滑軌，尤指一種線性滑軌之滑塊組接結構。 The invention relates to a linear slide rail, in particular to a sliding block assembly structure of the linear slide rail.

線性滑軌裝置主要是將滑塊結構安裝在軌道上，藉以進行直線反復運動。又，一般滑塊結構包含有U型滑塊、設置在滑塊相對側的二端蓋、設置在滑塊內的複數滾珠及將滾珠保持在滑塊上的保持元件。藉此，滑塊可透過滾珠來減少滑塊與軌道之間相對移動時的摩擦力，從而使滑塊的移動更為順暢。 The linear slide rail device is mainly to install the slider structure on the track, so as to perform linear and repetitive motion. Moreover, the general slider structure includes a U-shaped slider, two end caps arranged on opposite sides of the slider, a plurality of balls arranged in the slider, and a retaining element for retaining the balls on the slider. Thereby, the sliding block can reduce the frictional force during relative movement between the sliding block and the track through the balls, so that the sliding block can move more smoothly.

前述滑塊結構是利用保持元件來提供滾珠的滾動路徑。目前已有保持元件採用迴流管作為滾珠的直線通道，並將迴流管組接在端蓋的一側面。然而，在滾動循環的過程中，滑塊中的滾珠會在端蓋的位置處(即迴流管與端蓋組接位置)產生較大的衝擊力及振動。在此連續衝擊力及振動作用下，端蓋及迴流管之間會形成間隙或產生凹凸不平的現象而造成摩擦阻力，影響迴流管內的滾珠在滾動循環時的順暢性。 The aforementioned slider structure utilizes retaining elements to provide rolling paths for the balls. At present, the existing retaining elements use the return pipe as the linear passage of the ball, and the return pipe is assembled on one side of the end cover. However, during the rolling cycle, the balls in the slider will generate relatively large impact force and vibration at the position of the end cover (that is, the assembly position of the return pipe and the end cover). Under the action of this continuous impact force and vibration, a gap or unevenness will be formed between the end cover and the return pipe, which will cause frictional resistance and affect the smoothness of the balls in the return pipe during rolling and circulation.

有鑑於此，本發明人遂針對上述現有技術，特潛心研究並配合學理的運用，盡力解決上述之問題點，即成為本發明人改良之目標。 In view of this, the inventor of the present invention aimed at the above-mentioned prior art, devoted himself to research and combined with the application of theories, and tried his best to solve the above-mentioned problems, which became the goal of the inventor's improvement.

本發明之一目的，在於提供一種線性滑軌的滑塊組接結構，以避免滾珠的衝擊力造成端蓋及保持元件組分離，從而維持滾珠在滾動時的順暢性。 An object of the present invention is to provide a slider assembly structure of a linear slide rail, so as to avoid the separation of the end cover and the holding element group due to the impact force of the balls, so as to maintain the smoothness of the balls rolling.

為了達成上述之目的，本發明係為一種線性滑軌的滑塊組接結構，用以保持複數滾珠，包括滑塊、一對端蓋及複數保持元件組。滑塊具有滑槽、設置在滑槽之相對側的複數溝槽及複數貫通孔。端蓋設置在滑塊的相對側，各端蓋在面向滑塊的一側面成型有複數迴流槽、複數直通道凸片及複數支撐臂，各直通道凸片係位於各迴流槽遠離滑塊的一外側，各支撐臂位於各迴流槽接近滑塊的一內側並朝遠離迴流槽的方向凸伸。複數保持元件組相對接而穿置在滑塊中，各保持元件組包含複數保持筒件及複數側向保持片，保持筒件呈間隔設置且一側相連，各保持筒件包含管筒、凸露出管筒的迴流管及自迴流管延伸的直通道末段，各側向保持片設置在相連的複數保持筒件之間並具有支撐段；其中，端蓋對應結合在滑塊的相對側時，各保持筒件的一端靠抵在各直通道凸片的一端面，且各支撐臂係靠抵支撐段，迴流槽、迴流管及直通道末段圍合形成連通直通道末段的迴流彎道。 In order to achieve the above purpose, the present invention is a slider assembly structure of a linear slide rail for holding multiple balls, including a slider, a pair of end caps and a plurality of holding element groups. The sliding block has a sliding groove, a plurality of grooves and a plurality of through holes arranged on opposite sides of the sliding groove. The end caps are arranged on the opposite side of the slider, and each end cap is formed with a plurality of return channels, a plurality of straight channel fins and a plurality of support arms on the side facing the slider, and each straight channel tab is located at the side of each return channel away from the slider. An outer side, each supporting arm is located on an inner side of each backflow slot close to the slider and protrudes toward a direction away from the backflow slot. A plurality of holding element groups are butted and inserted in the slider. Each holding element group includes a plurality of holding cylinders and a plurality of lateral holding sheets. The holding cylinders are arranged at intervals and connected on one side. Each holding cylinder includes a tube, a convex The return pipe exposed from the tube and the end section of the straight channel extending from the return pipe, each side holding piece is arranged between the plurality of connected holding cylinders and has a supporting section; wherein, when the end cover is correspondingly combined with the opposite side of the slider , one end of each retaining cylinder leans against one end surface of each straight channel lug, and each support arm is tied against the support section, and the return groove, the return pipe and the end section of the straight channel are enclosed to form a return bend connected to the end section of the straight channel road.

The support arm is located on the inner side of the backflow groove close to the slider and faces away from the backflow groove. In addition, a supporting section is provided on the lateral holding piece of the holding element group, so that when the end cover is correspondingly combined on the opposite side of the slider, the supporting arm will lean against the supporting section, because the supporting arm is on the outside of the return groove. Resist the lateral retaining piece and support the retaining cylinder to avoid gaps or detachment at the intersection of the retaining cylinder and the end cover due to the impact and vibration of the ball when turning, so as to maintain the smoothness of the ball when rolling .
