Description

液靜壓線性滑軌Hydrostatic Linear Slide

本創作涉及一種液靜壓線性滑軌，尤其是涉及一種可降低滑軌上的應力、防止滑軌受力變形的液靜壓線性滑軌。 This creation relates to a hydrostatic linear slide rail, in particular to a hydrostatic linear slide rail that can reduce the stress on the slide rail and prevent the slide rail from being deformed by force.

現有的液靜壓線性滑軌，例如專利TWM605250和WO2000012908A1，在滑軌的相對二側表面上各凹設有一滑槽，並且滑塊與滑槽的上下壁之間會形成油膜。由於滑塊沒有包覆到滑槽下方的側表面，因此滑塊與滑槽下方的側表面(無負荷區)不會形成油膜。 Existing hydrostatic linear slide rails, such as patents TWM605250 and WO2000012908A1, each have a chute recessed on two opposite side surfaces of the slide rail, and an oil film is formed between the slide block and the upper and lower walls of the chute. Since the slider does not cover the side surface under the chute, the slider and the side surface (no load area) under the chute will not form an oil film.

此外，TWM605250的滑軌的滑槽的上下壁長，導致滑軌總寬也隨之變大，經由應力分析之後，滑軌的結構強度不佳。WO2000012908A1的液靜壓線性滑軌則是在使用時，液靜壓內部的液壓流體會溢出至外部，影響工具機的使用環境。 In addition, the upper and lower walls of the chute of the slide rail of TWM605250 are long, which leads to an increase in the total width of the slide rail. After stress analysis, the structural strength of the slide rail is not good. In the hydrostatic linear slideway of WO2000012908A1, when in use, the hydraulic fluid inside the hydrostatic pressure will overflow to the outside, which will affect the use environment of the machine tool.

A load portion 15 is provided on each of the two opposite inner surfaces 13 . The portions of each inner surface 13 located on the upper and lower sides of the load portion 15 are defined as two first oil sealing surfaces 131 and 132 . Each load portion 15 of the slider 10 has two second oil sealing surfaces 151 and 152 , a connecting surface 153 located between the two second oil sealing surfaces 151 and 152 and connecting the two, and is concave by the second oil sealing surface 151 . A first oil groove area 154 , a second oil groove area 155 and a third oil groove area 156 recessed from the connecting surface 153 are provided. The two second oil sealing surfaces 151 and 152 of each load portion 15 are respectively connected to the two first oil sealing surfaces 131 and 132 on the upper and lower sides of the load portion 15 . The second oil groove area 155 of the second oil sealing surface 151 surrounds the upper side (the upper part in the figure) and the left and right sides (the left and right sides in the figure) of the first oil groove area 154 , and the second oil groove area of the second oil sealing surface 152 155 surrounds the left and right sides and the lower side of the first oil sump area 154 (the lower part in the figure). The third oil groove area 156 communicates with the corresponding upper and lower second oil groove areas 155 .

滑軌20，如圖1-3和圖6所示，是沿一第一軸向D1延伸。滑軌20於其相對二側表面21各凹設一第二滑槽22。各側表面21位於對應的第二滑槽22上下側的部分分別定義為二第一滑道面211和212。這兩個第二滑槽22分別用以容納滑塊10的二負荷部15。各個第二滑槽22具有分別連接二第一滑道面211和212的第二滑道面221和222以及位於第二滑道面221和222之間且連接兩者的一支撐面223。各個第二滑槽22的第二滑道面221和222的延伸相交處P會經過一基準面BS1。基準面BS1為水平面。各個第二滑槽22的第二滑道面221和222分別與基準面BS1之間具有一第一夾角α和一第二夾角β。各個第二滑槽22的第二滑道面221和222的夾角(即第一夾角α和第二夾角β的總和)可例如但不限於小於90度。第一夾角α和第二夾角β皆可例如但不限於大於0度且小於90度。較佳的是，第一夾角α大致相等於第二夾角β。因此，各個第二滑槽22的二第二滑道面221和212分別是朝相對方向傾斜的傾斜面。滑軌20各側的第一滑道面211和212相互切齊，且第一滑道面211和支撐面223皆為垂直面且相互平行。 The slide rail 20, as shown in FIGS. 1-3 and 6, extends along a first axial direction D1. A second sliding groove 22 is recessed on two opposite side surfaces 21 of the slide rail 20 . The portions of each side surface 21 located on the upper and lower sides of the corresponding second chute 22 are respectively defined as two first chute surfaces 211 and 212 . The two second sliding grooves 22 are respectively used to accommodate the two load parts 15 of the slider 10 . Each of the second sliding grooves 22 has a second sliding surface 221 and 222 connecting the two first sliding surfaces 211 and 212 respectively, and a supporting surface 223 located between the second sliding surfaces 221 and 222 and connecting the two. The extending intersection P of the second sliding surfaces 221 and 222 of each of the second sliding grooves 22 will pass through a reference plane BS1 . The reference plane BS1 is a horizontal plane. of each second chute 22 There are a first included angle α and a second included angle β between the second slideway surfaces 221 and 222 and the reference plane BS1 , respectively. The included angle between the second sliding surfaces 221 and 222 of each of the second sliding grooves 22 (ie, the sum of the first included angle α and the second included angle β) may be, for example, but not limited to, less than 90 degrees. Both the first included angle α and the second included angle β can be, for example but not limited to, greater than 0 degrees and less than 90 degrees. Preferably, the first included angle α is substantially equal to the second included angle β. Therefore, the two second sliding surfaces 221 and 212 of each of the second sliding grooves 22 are respectively inclined surfaces inclined in opposite directions. The first sliding surfaces 211 and 212 on each side of the sliding rail 20 are aligned with each other, and the first sliding surface 211 and the supporting surface 223 are both vertical and parallel to each other.

並且，滑軌20各側的第一滑道面211、212和相鄰的第二滑道面221、222不共面，如圖6所示。較佳的是，第一滑道面212與一基準面BS2之間的第三夾角γ大於60度且小於等於90度，最佳的是90度。基準面BS2為水平面。藉此，經由應力分析之後，可降低滑軌20在使用時所承受的應力，以降低變形量。 In addition, the first sliding surface 211 and 212 on each side of the sliding rail 20 and the adjacent second sliding surfaces 221 and 222 are not coplanar, as shown in FIG. 6 . Preferably, the third angle γ between the first slide surface 212 and a reference plane BS2 is greater than 60 degrees and less than or equal to 90 degrees, and the most preferred is 90 degrees. The reference plane BS2 is a horizontal plane. In this way, after stress analysis, the stress on the slide rail 20 during use can be reduced, so as to reduce the amount of deformation.

以下針對不同的第三夾角γ對滑軌的應力值和變形量的影響進行試驗，其中第一滑軌的第三夾角γ為90度，第二滑軌的第三夾角γ為45度，第三滑軌的第三夾角γ為60度，且這三個滑軌的其餘條件相同。在相同的試驗條件下，第二滑軌上的應力值比第一滑軌上的應力值大了約47%，第二滑軌的變形量比第一滑軌的變形量大了約52%；第三滑軌上的應力值比第一滑軌上的應力值大了約7%，第三滑軌的變形量比第一滑軌的變形量大了約11%。由上述試驗結果可知，第一滑軌在應力值和變形量上的表現都較第二滑軌和第三滑軌優異，因此當第三夾角γ大於60度且小於等於90度時，可有效降低滑軌在使用時所承受的應力值，相對地也可有效地降低變形量。 The following tests are conducted on the influence of different third included angles γ on the stress value and deformation of the slide rail. The third included angle γ of the first slide rail is 90 degrees, the third included angle γ of the second slide rail is 45 degrees, and the third The third included angle γ of the three slide rails is 60 degrees, and other conditions of the three slide rails are the same. Under the same test conditions, the stress value on the second slide rail is about 47% larger than that on the first slide rail, and the deformation of the second slide rail is about 52% larger than that of the first slide rail ; The stress value on the third slide rail is about 7% larger than that on the first slide rail, and the deformation of the third slide rail is about 11% larger than that of the first slide rail. From the above test results, it can be seen that the performance of the first slide rail is better than that of the second slide rail and the third slide rail in terms of stress value and deformation. Therefore, when the third angle γ is greater than 60 degrees and less than or equal to 90 degrees, it can be effectively Reducing the stress value of the slide rail in use can also effectively reduce the amount of deformation.

各端蓋組件30，如圖1-2、圖4-5和圖10-13所示，也設置有一輸油網路31。輸油網路31是由多個油道311構成。其中一端蓋組件30的輸油網路31，如圖11所示，在此端蓋組件30的其中一外側面32上有一開口312，在此端蓋組件30朝向滑塊10的一端面33上有二個開口313，這兩個開口313分別對接滑塊10的其中一端面11上的二個開口168。另一個端蓋組件30的輸油網路31，如圖12所示，在此端蓋組件30的其中一外側面32上也有一開口312，在此端蓋組件30朝向滑塊10的另一端面33上有多個開口314，這些開口314分別對接滑塊10的另一端面33上的開口169。因此，各端蓋組件30的輸油網路31可連通滑塊10的輸油網路16。 Each end cap assembly 30, as shown in Figures 1-2, 4-5 and 10-13, is also provided with an oil delivery network 31. The oil transmission network 31 is constituted by a plurality of oil passages 311 . As shown in FIG. 11 , the oil transmission network 31 of the end cover assembly 30 has an opening 312 on one of the outer side surfaces 32 of the end cover assembly 30 , and an end face 33 of the end cover assembly 30 faces the slider 10 There are two openings 313 , and the two openings 313 are respectively connected to the two openings 168 on one end surface 11 of the slider 10 . The oil delivery network 31 of the other end cover assembly 30, as shown in FIG. 12, also has an opening 312 on one of the outer side surfaces 32 of the end cover assembly 30, where the end cover assembly 30 faces the other side of the slider 10. The end surface 33 has a plurality of openings 314 , and the openings 314 are respectively connected to the openings 169 on the other end surface 33 of the slider 10 . Therefore, the oil transmission network 31 of each end cover assembly 30 can communicate with the oil transmission network 16 of the slider 10 .

此外，如圖3所示，滑塊10各側的第一封油面131和132、第二封油面151和152及連接面153分別對應(或面向)滑軌20對應一側的第一滑道面211和212、第二滑道面221和222及支撐面223。因此，當油經由輸油網路16位於滑塊10的各負荷部15上的開口162-165，如圖3-4和圖7-9所示，進入滑塊10的第一滑槽12時，各第一封油面131與對應的第一滑道面211之間、各第一封油面132與對應的第一滑道面212之間、各第二封油面151與對應的第二滑道面221之間、各第二封油面152與對應的第二滑道面222之間以及各連接面153與對應的支撐面223之間會形成油膜。 In addition, as shown in FIG. 3 , the first oil sealing surfaces 131 and 132 , the second oil sealing surfaces 151 and 152 and the connecting surface 153 on each side of the slider 10 correspond to (or face) the first oil sealing surfaces on the corresponding side of the slide rail 20 , respectively. The slideway surfaces 211 and 212 , the second slideway surfaces 221 and 222 and the support surface 223 . Therefore, when the oil enters the first chute 12 of the slider 10 through the openings 162-165 of each load portion 15 of the slider 10 through the oil delivery network 16, as shown in Figs. 3-4 and 7-9 , the difference between each first oil sealing surface 131 and the corresponding first sliding surface 211 between each first oil sealing surface 132 and the corresponding first sliding surface 212, between each second oil sealing surface 151 and the corresponding second sliding surface 221, and each second oil sealing surface 152 and the corresponding An oil film is formed between the second slide surfaces 222 and between each connecting surface 153 and the corresponding supporting surface 223 .

如此一來，滑塊10的輸油網路16與各端蓋組件30的輸油網路31便可共同構成一循環路徑，使油可利用循環路徑內的壓力差而流竄於二個端蓋組件30與滑塊10之間。 In this way, the oil transmission network 16 of the slider 10 and the oil transmission network 31 of each end cover assembly 30 can jointly form a circulation path, so that the oil can flow through the two end covers by utilizing the pressure difference in the circulation path. Between the assembly 30 and the slider 10 .

另一方面，為了防止油外洩，本創作的液靜壓線性滑軌可更包含環狀的二密封件40。二密封件40是沿第一軸向D1分別配置於滑塊10和滑軌20之間，分別位於第一滑槽12內的相對二側及滑軌20的相對二側，如圖3所示。詳細來說，如圖5所示，滑塊10的第一封油面131和132各設有相對的一凹陷區181，且對應的負荷部15位於這兩個凹陷區181之間；滑塊10的各端面11在第一滑槽12的相對二側也各別地設有一凹陷區182，此凹陷區182也由同一側的第一封油面131和132凹入；且位於滑塊10同一側的兩凹陷區181與兩凹陷區182連通而共同構成一凹槽18，以容納密封件40。由於各凹槽18圍繞對應的負荷部15，因此凹槽18內的密封件40也圍繞此負荷部15，如圖4所示。也就是說，密封件40不僅可延伸於第一封油面131和132，也可延伸於第二封油面151和152及連接面153，以將對應負荷部15上所有的油槽區圈入在內。 On the other hand, in order to prevent oil from leaking out, the hydrostatic pressure linear slide rail of the present invention may further include two annular seals 40 . The two seals 40 are respectively disposed between the slider 10 and the slide rail 20 along the first axial direction D1, and are respectively located on two opposite sides of the first slide groove 12 and two opposite sides of the slide rail 20, as shown in FIG. 3 . . In detail, as shown in FIG. 5 , each of the first oil sealing surfaces 131 and 132 of the slider 10 is provided with a corresponding recessed area 181 , and the corresponding load portion 15 is located between the two recessed areas 181 ; Each end surface 11 of 10 is also provided with a concave area 182 on two opposite sides of the first chute 12, and this concave area 182 is also concave by the first oil sealing surfaces 131 and 132 on the same side; The two concave areas 181 on the same side communicate with the two concave areas 182 to form a groove 18 for accommodating the sealing element 40 . Since each groove 18 surrounds the corresponding load portion 15 , the seal 40 in the groove 18 also surrounds the load portion 15 , as shown in FIG. 4 . That is to say, the sealing member 40 can not only extend on the first oil sealing surfaces 131 and 132 , but also extend on the second oil sealing surfaces 151 and 152 and the connecting surface 153 , so as to enclose all the oil groove areas on the corresponding load part 15 . inside.

又如圖5所示，在滑塊10的各側，第二封油面151位於對應的第一油槽區154和對應的第二油槽區155之間的部分以及位於對應的第一油槽區154和對應的第三油槽區156之間的部分可定義為一內封油圈，第二封油面152位於對應的第一油槽區154和對應的第二油槽區155之間的部分以及位於對應的第一油槽區154和對應的第三油槽區156之間的部分可定義為另一內封油圈。並且，在滑塊10的各側，第一封油面131位於對應的凹陷區181與對應的負荷部15之間的部分可定義為一封油區域R1，第一封油面132位於對應的凹陷區181與對應的負荷部15之間的部分可定義為一封油區域R2，第二封油面151位於對應的第二油槽區155與對應的左右側之凹陷區182之間的部分可定義為封油區域R3和R4，第二封油面152位於對應的第二油槽區155與對應的左右側之凹陷區182之間的部分可定義為封油區域R5和R6，連接面153位於第三油槽區156與對應的左右側之凹陷區182之間的部分可定義為封油區域R7和R8，且這些封油區域R1至R8共同構成可包圍所有的油槽區和二內封油圈的一外封油圈。因此，油膜將會形成在內封油圈和外封油圈的位置。值得一提的是，內封油圈與滑軌20之間產生的油膜會形成流動阻力，鎖住第一油槽區154的高壓力，使滑塊10產生負荷區，進而使滑塊10與滑軌20做非接觸低摩擦的運動，降低滑塊10與滑軌20的損耗。外封油圈與滑軌20之間產生的油膜也會形成流動阻力，避免第二油槽區155與第三油槽區156的油脂直接沖向密封件40，造成密封件的損壞。 As also shown in FIG. 5 , on each side of the slider 10 , the second oil sealing surface 151 is located between the corresponding first oil groove area 154 and the corresponding second oil groove area 155 and is located in the corresponding first oil groove area 154 The part between the corresponding third oil groove area 156 and the corresponding third oil groove area 156 can be defined as an inner oil sealing ring, and the second oil sealing surface 152 is located between the corresponding first oil groove area 154 and the corresponding second oil groove area 155. And the part between the corresponding first oil groove area 154 and the corresponding third oil groove area 156 can be defined as another inner sealing oil ring. In addition, on each side of the slider 10, the part of the first oil sealing surface 131 between the corresponding recessed area 181 and the corresponding load part 15 can be defined as the oil sealing area R1, and the first oil sealing surface 132 is located in the corresponding The part between the concave area 181 and the corresponding load part 15 can be defined as an oil sealing area R2, and the part of the second oil sealing surface 151 between the corresponding second oil groove area 155 and the corresponding left and right concave areas 182 can be defined. Defined as oil sealing regions R3 and R4, the part of the second oil sealing surface 152 between the corresponding second oil groove region 155 and the corresponding left and right concave regions 182 can be defined as oil sealing regions R5 and R6, and the connecting surface 153 is located at The part between the third oil groove area 156 and the corresponding left and right concave areas 182 can be defined as oil sealing areas R7 and R8, and these oil sealing areas R1 to R8 together constitute the two inner oil sealing rings that can surround all the oil groove areas an outer seal oil ring. Therefore, an oil film will be formed at the position of the inner oil ring and the outer oil ring. It is worth mentioning that the oil film generated between the inner sealing oil ring and the slide rail 20 will form a flow resistance, lock the high pressure of the first oil groove area 154, and make the slider 10 generate a load area, thereby making the slider 10 and the slider 10. The rail 20 performs non-contact and low-friction motion, reducing the loss of the slider 10 and the slide rail 20 . The oil film generated between the outer sealing oil ring and the slide rail 20 will also form a flow resistance to prevent the grease in the second oil groove area 155 and the third oil groove area 156 from directly rushing to the seal 40 and damage to the seal.

並且，各個密封件40在其相對的二位置上設置有一第一接合結構41和一第二接合結構42，如圖2和圖13所示。滑塊10的各端面11上的相對二凹陷區182內分別設有一第三接合結構183和一第四接合結構184，如圖10所示。其中一個密封件40的第一接合結構41和第二接合結構42分別與滑塊10的二端面11的二第三接合結構183相接，其中另一個密封件40的第一接合結構41和第二接合結構42分別與滑塊10的二端面11的二第四接合結構184相接。藉此，二密封件40便可固定於滑塊10。 Moreover, each sealing member 40 is provided with a first engaging structure 41 and a second engaging structure 42 at two opposite positions thereof, as shown in FIG. 2 and FIG. 13 . A third engaging structure 183 and a fourth engaging structure 184 are respectively provided in two opposite recessed areas 182 on each end surface 11 of the slider 10 , as shown in FIG. 10 . The first engagement structure 41 and the second engagement structure 42 of one of the seals 40 are respectively connected to the two third engagement structures 183 of the two end faces 11 of the slider 10 , and the first engagement structure 41 and the second engagement structure of the other seal 40 The two engaging structures 42 are respectively connected to the two fourth engaging structures 184 on the two end surfaces 11 of the slider 10 . In this way, the two seals 40 can be fixed to the slider 10 .

本實施例組裝後，如圖13所示，各個密封件40會延伸於與其同側的二第一滑道面211和212，且抵頂於二端蓋組件30的端面33，藉此滑塊10和滑軌20之間於各密封件40圍繞的範圍內可形成一封閉空間。此時，進入滑塊10和滑軌20之間的油會在此封閉空間中的各油槽區內循環，而不會溢出封閉空間之外，例如不會漫延至滑塊10的底面14與滑軌20之間的間隙、端蓋組件30遠離滑塊10的端面33、液靜壓線性滑軌的底部等。因此，無須額外接上抽油機，油便可根據輸油網路16和31的開口之間的液壓差，在液靜壓線性滑軌內自動循環排出。 After the present embodiment is assembled, as shown in FIG. 13 , each sealing member 40 will extend on the two first slideway surfaces 211 and 212 on the same side thereof, and abut against the end surfaces 33 of the two end cap assemblies 30 , whereby the sliding block A closed space can be formed between the 10 and the slide rail 20 within the range surrounded by each seal 40 . At this time, the oil entering between the slider 10 and the slide rail 20 will circulate in each oil groove area in the closed space, and will not overflow outside the closed space, for example, will not spread to the bottom surface 14 of the slider 10 and the slider. The gap between the rails 20, the end face 33 of the end cap assembly 30 away from the slider 10, the bottom of the hydrostatic linear slide rail, etc. Therefore, the oil can be automatically circulated and discharged in the hydrostatic linear slide rail according to the hydraulic pressure difference between the openings of the oil delivery networks 16 and 31 without an additional oil pumping unit.

在本創作中，關於各負荷部15上的油槽區的數量、位置和尺寸、液靜壓線性滑軌內的輸油網路的分佈以及輸油網路的開口的數量和位置的實施態樣並不限於圖1-13所呈現的，而是可根據實際需求來設計。 In this creation, the number, position and size of the oil groove area on each load part 15, the distribution of the oil transmission network in the hydrostatic linear slide rail, and the number and position of the openings of the oil transmission network are implemented. It is not limited to what is presented in Figures 1-13, but can be designed according to actual needs.

綜上所述，本創作的液靜壓線性滑軌藉由讓滑軌20的四個翼部23，尤其是下方的二個第一滑道面212，被滑塊10包覆，使得滑軌20的翼部23在垂直於第一軸向D1的第二軸向D2上伸出的長度可被縮短，因此可降低在翼部23上的應力值，從而降低滑軌20的變形量。倘若滑軌20進一步搭配上述第三夾角γ的設計，亦即第一滑道面212的傾斜程度的設計，可獲得更明顯的改善效果。此外，本創作的液靜壓線性滑軌還藉由各油槽區、開口和輸油網路的搭配，使液靜壓線性滑軌內部可形成利用液壓差作為流體動力來源的循環系統，並且在各封油面與其對應的滑道面之間以及各連接面與其對應的支撐面之間，尤其是內、外封油圈的位置，會形成油膜。更佳的是，在滑塊10和滑軌20之間設置密封件40，並且讓密封件40圍繞所有的油槽區以及內、外封油圈，因此可防止流體從液靜壓線性滑軌的各縫隙溢出至外部。 To sum up, in the hydrostatic linear slide rail of the present invention, the four wings 23 of the slide rail 20, especially the two first slide surfaces 212 below, are covered by the slider 10, so that the slide rail is The protruding length of the wing portion 23 of the wing portion 20 in the second axial direction D2 perpendicular to the first axial direction D1 can be shortened, so that the stress value on the wing portion 23 can be reduced, thereby reducing the deformation amount of the slide rail 20 . If the sliding rail 20 is further matched with the above-mentioned design of the third included angle γ, that is, the design of the inclination of the first sliding surface 212, a more obvious improvement effect can be obtained. In addition, the hydrostatic linear slide of this creation can also form a circulation system using hydraulic pressure difference as a source of fluid power inside the hydrostatic linear slide through the combination of various oil grooves, openings and oil transmission networks, and in the An oil film will be formed between each oil sealing surface and its corresponding sliding surface, and between each connecting surface and its corresponding supporting surface, especially the positions of the inner and outer oil sealing rings. More preferably, a seal 40 is provided between the slider 10 and the slide rail 20, and the seal 40 surrounds all Therefore, the fluid can be prevented from overflowing from the gaps of the hydrostatic linear slide to the outside.
