Description

直線傳動系統Linear drive system

本新型關於一種直線傳動系統，特別關於一種不需拆解裝置就可調整偏位預壓的直線傳動系統。The present invention relates to a linear transmission system, and in particular to a linear transmission system that can adjust the bias preload without disassembling the device.

直線傳動裝置，例如滾珠螺桿是一種廣泛應用在許多機械加工設備中的裝置，其設置的目的在於提供精密的傳動功能，藉由機械操作中的旋轉運動與直線運動，進而使承載的機台或物件可於直線方向上進行作動。目前所應用的滾珠螺桿裝置主要係由一螺桿、一螺帽以及複數滾珠所構成。螺桿之外表面係具有螺旋式溝槽，螺帽之內表面亦具有螺旋式內溝槽，其能與螺桿間形成一滾珠通道，使滾珠容置於其中，並與螺桿、螺帽形成相對滾動的關係，以降低螺桿與螺帽之間相對轉動之摩擦力。Linear transmission devices, such as ball screws, are widely used in many machining equipment. The purpose of their setting is to provide precise transmission functions. Through the rotary motion and linear motion in mechanical operation, the bearing machine or Objects can be moved in a straight direction. The ball screw device currently used is mainly composed of a screw, a nut and a plurality of balls. The outer surface of the screw has a spiral groove, and the inner surface of the nut also has a spiral inner groove, which can form a ball channel with the screw, so that the ball is accommodated therein, and forms a relative rolling with the screw and the nut To reduce the friction between the screw and the nut.

在實際應用方面，僅有一個螺帽的滾珠螺桿裝置無法滿足重型機具的重負荷要求，因此雙螺帽式的滾珠螺桿裝置便應運而生。在雙螺帽的滾珠螺桿裝置中，為了使兩螺帽之間存在一預壓力，以清除兩螺帽與螺桿之間所承受軸向負荷的彈性形變量，進而達到高定位精度，乃於兩螺帽之間設有一預壓片，使螺帽與螺桿的珠溝產生足夠偏位，達到偏位預壓的目的。In terms of practical application, the ball screw device with only one nut cannot meet the heavy load requirements of heavy equipment, so the double nut type ball screw device came into being. In the double-screw ball screw device, in order to make a pre-pressure between the two nuts, to eliminate the elastic deformation of the axial load between the two nuts and the screw, and to achieve high positioning accuracy, it is better than the two There is a pre-compression piece between the nuts, so that the nut and the bead groove of the screw can be offset enough to achieve the purpose of offset pre-compression.

然而，上述的雙螺帽滾珠螺桿裝置需要在兩螺帽之間加入預壓片，如此，整個裝置的元件數量較多，容易因為製作過程所產生的公差而影響整個裝置的定位精度。另外，在得知預壓力已產生偏移時，習知技術必須停止加工作業且拆解滾珠螺桿裝置後，才能更換構件及/或重新調整滾珠與螺帽之間的偏位預壓，如此，會增加相當多的作業時間與成本，產能也會降低。However, the above double nut ball screw device needs to add a pre-compression sheet between the two nuts, so the number of components of the entire device is large, and it is easy to affect the positioning accuracy of the entire device due to tolerances generated during the manufacturing process. In addition, when it is known that the pre-pressure has shifted, the conventional technology must stop the processing operation and disassemble the ball screw device before the component can be replaced and/or the pre-pressure offset between the ball and the nut can be readjusted. It will increase a considerable amount of operation time and cost, and the production capacity will also decrease.

本新型之目的為提供一種直線傳動系統，可在不需拆解裝置的情況下就可調整其偏位預壓值，藉此，不僅不會增加作業時間與成本，對產能的影響也相當有限。The purpose of the new model is to provide a linear transmission system that can adjust its bias preload value without disassembling the device, thereby not only does not increase operating time and cost, but also has a very limited impact on production capacity .

Wherein, the preload adjuster 152 is provided with a fixing member 153, and one end surface 1522 of the preload adjuster 152 abuts the adjusting rod 1512 to provide a fixed thrust to press against the adjusting rod 1512. The fixed thrust can be pressed (top The adjustment lever 1512, so that the other end of the adjustment lever 1512 (the end away from the adjustment member 1511) also provides a fixed force to press the adjustment member 1511 to press the outer side of the nut 12b, so that the rolling elements (balls) 13a, 13b The pre-pressure values generated by the caps 12a and 12b can be maintained at a certain value (for example, a predetermined value), thereby achieving the effects of bias pre-pressure and semi-automatic compensation.

請先參照圖4所示，其為一實施例之預壓調整器的剖視示意圖。預壓調整器152為一種可提供固定推力的阻尼推力器，其具有殼體f，而殼體f內部包括有第一腔體a、第二腔體b、活塞桿c、活塞（由墊片與簧片構成）d。另外，預壓調整器152還可包括第三腔體e。第一腔體a與第二腔體b連通，並充滿油體（亦即油體可於第一腔體a與第二腔體b之間流動），而第三腔體e內充滿著氣體（例如氮氣），在預壓調整器152作動時，第三腔體e內的氣體同時壓縮使內壓力達到平衡。另外，活塞d兩側均設有簧片，簧片可控制活塞d的小孔開合，藉由兩側小孔開合大小的不同，可使預壓調整器152壓縮及回彈時產生不同速度，藉此達到穩定推力的效果。因此，預壓調整器152內部的油體可通過活塞d的小孔在第一腔體a和與第二腔體b之間流動，透過活塞d上簧片的控制產生不同阻力，使活塞桿c產生一定的推力來頂住調整桿1512，藉此提供固定的推力給調整桿1512，進而透過調整件1511維持該些滾動件13a、13b對移動件所產生的預壓力值在一預定值。Please refer to FIG. 4 first, which is a schematic cross-sectional view of a preload regulator according to an embodiment. The preload regulator 152 is a damping thruster that can provide a fixed thrust, and has a housing f, and the housing f includes a first cavity a, a second cavity b, a piston rod c, a piston (by a gasket Composition with reed) d. In addition, the preload regulator 152 may further include a third cavity e. The first cavity a communicates with the second cavity b and is filled with oil (that is, the oil can flow between the first cavity a and the second cavity b), and the third cavity e is filled with gas (For example, nitrogen gas), when the pre-pressure regulator 152 is activated, the gas in the third cavity e is simultaneously compressed to balance the internal pressure. In addition, the reeds are provided on both sides of the piston d. The reeds can control the opening and closing of the small holes of the piston d. With the difference in the opening and closing sizes of the small holes on both sides, the preload regulator 152 can be compressed and rebound differently. Speed, thereby achieving the effect of stabilizing thrust. Therefore, the oil inside the pre-pressure regulator 152 can flow between the first cavity a and the second cavity b through the small hole of the piston d, and different resistances are generated through the control of the reed on the piston d, so that the piston rod c generates a certain pushing force against the adjusting lever 1512, thereby providing a fixed pushing force to the adjusting lever 1512, and then maintaining the pre-pressure value of the rolling members 13a, 13b on the moving member at a predetermined value through the adjusting member 1511.

因此，本實施例之直線傳動系統1可以在不需拆解裝置的情況下就可透過預壓調整模組15的預壓調整器152及預壓組件151維持滾動件13a、13b與螺帽12a、12b之間的預壓力值在一預定值，藉此，不僅不需要拆解裝置而增加作業時間與成本，對產能也不會造成影響。Therefore, the linear transmission system 1 of this embodiment can maintain the rolling elements 13a, 13b and the nut 12a through the preload adjuster 152 and the preload assembly 151 of the preload adjustment module 15 without disassembling the device The pre-pressure value between 12b and 12b is at a predetermined value, thereby not only does not need to disassemble the device and increases the operating time and cost, but also does not affect the production capacity.

圖5為依據本新型另一實施例之一種直線傳動系統的示意圖，而圖6A為圖5所示之直線傳動系統的局部剖視示意圖。FIG. 5 is a schematic diagram of a linear transmission system according to another embodiment of the present invention, and FIG. 6A is a partial cross-sectional schematic diagram of the linear transmission system shown in FIG. 5.

如圖5與圖6A所示，本實施例的直線傳動系統1a與前述實施例之直線傳動系統1大致相同。與上述實施例主要的不同在於，本實施例的直線傳動系統1a更可包括一預壓感測件16（圖6A）及一監控器17（圖5），預壓感測件16設置於移動件，以偵測預壓力值。於此，預壓感測件16可設置於兩螺帽12a、12b的至少其中之一、或載台本體14，並與監控器17電性連接，以偵測該些滾動件13a、13b對移動件所產生的預壓力值而輸出一偵測訊號SS傳送至監控器17。其中，預壓感測件16的形狀並不限制，其可為圓筒狀、薄片狀、薄膜狀或其他形狀。本實施例的預壓感測件16例如但不限於為應變規（Strain Gauge）為例。As shown in FIGS. 5 and 6A, the linear transmission system 1a of this embodiment is substantially the same as the linear transmission system 1 of the foregoing embodiment. The main difference from the above embodiment is that the linear transmission system 1a of this embodiment may further include a pre-pressure sensor 16 (FIG. 6A) and a monitor 17 (FIG. 5). The pre-pressure sensor 16 is disposed on the mobile To detect the pre-pressure value. Here, the preload sensing element 16 may be disposed on at least one of the two nuts 12a, 12b, or the stage body 14, and electrically connected with the monitor 17 to detect the pair of the rolling elements 13a, 13b The pre-pressure value generated by the moving part outputs a detection signal SS and sends it to the monitor 17. The shape of the pre-pressure sensor 16 is not limited, and it may be cylindrical, thin, thin, or other shapes. The pre-pressure sensor 16 of this embodiment is, for example but not limited to, a strain gauge (Strain Gauge) as an example.

另外，本實施例是以一個預壓感測件16設置於螺帽12a（圖6A）為例。在不同的實施例中，也可多個預壓感測件16設置於螺帽12a、12b的至少其中之一、或載台本體14；或者，預壓感測件16也可設置於螺帽12b，或者在螺帽12a、12b分別設置至少一個預壓感測件16；又或者，預壓感測件16也可設置於載台本體14；又或者，如圖6B所示，預壓感測件16也可設置於螺帽12b，本申請都不限制。此外，請再參照圖5所示，本實施例的預壓感測件16是經由（穿過）載台本體14的頂面141而設置於螺帽12a，在不同的實施例中，預壓感測件16也可經由（穿過）載台本體14的側面142而設置於螺帽12a，本申請也不限制。In addition, in this embodiment, an example in which one pre-pressure sensing element 16 is provided on the nut 12a (FIG. 6A) is provided. In different embodiments, a plurality of pre-pressure sensing elements 16 may be provided on at least one of the nuts 12a, 12b, or the stage body 14; alternatively, the pre-pressure sensing elements 16 may also be provided on the nut 12b, or at least one pre-pressure sensor 16 is provided on the nuts 12a, 12b; alternatively, the pre-pressure sensor 16 may also be provided on the stage body 14; or, as shown in FIG. 6B, the pre-pressure sensor The test piece 16 may also be provided on the nut 12b, which is not limited in this application. In addition, please refer to FIG. 5 again, the preload sensing element 16 of this embodiment is disposed (through) the top surface 141 of the stage body 14 on the nut 12a. In different embodiments, the preload The sensor 16 may also be disposed on the nut 12a via (through) the side surface 142 of the stage body 14, and the present application is not limited.

因此，在直線傳動系統1a中，當滾珠螺桿裝置運行時，平行引導件11之長軸方向（方向X）的水平分力會被預壓感測件16偵測到而輸出偵測訊號SS至監控器17，監控器17可以經由換算後得到真正的預壓力值。其中，由於水平分力除以預壓力值等於餘弦函數，因此，若得知該水平分力、該預壓力和該水平方向的夾角時，就可利用餘弦函數反推而得到真正的預壓力值。Therefore, in the linear transmission system 1a, when the ball screw device is operating, the horizontal component of the long axis direction (direction X) of the parallel guide 11 will be detected by the pre-pressure sensing element 16 and output the detection signal SS to The monitor 17 can obtain the real pre-pressure value after conversion. Among them, because the horizontal component divided by the pre-pressure value is equal to the cosine function, so if you know the angle between the horizontal component, the pre-pressure and the horizontal direction, you can use the cosine function to reversely get the real pre-pressure value .

另外，前述的監控器17可例如但不限於電腦或伺服器，而預壓感測件16與監控器17可為有線或無線的電性連接。本實施例的監控器17是電腦，並與預壓感測件16有線連接為例。在本實施例中，監控器17可包括一顯示螢幕171，且監控器17可依據得到的偵測訊號SS經計算後使顯示螢幕171即時地顯示當前的預壓力值，供使用者參考。在一些實施例中，監控器17可位於滾珠螺桿裝置的近端（機台旁邊）、遠端（例如中央控制室），或者位於一雲端裝置中（此時，監控器17與預壓感測件16可透過無線通訊而彼此電連接）。此外，在一些實施例中，監控器17可將偵測訊號SS及預壓力值傳送至雲端裝置，以進行資料和訊號的統計及分析，進而讓使用者可透過這些資料了解直線傳動系統的運作情況。In addition, the aforementioned monitor 17 may be, for example but not limited to, a computer or a server, and the pre-pressure sensing element 16 and the monitor 17 may be wired or wirelessly electrically connected. The monitor 17 of this embodiment is a computer, and is connected to the pre-pressure sensing element 16 by way of example. In this embodiment, the monitor 17 may include a display screen 171, and the monitor 17 may cause the display screen 171 to display the current pre-pressure value in real time after calculation according to the obtained detection signal SS for reference by the user. In some embodiments, the monitor 17 may be located at the proximal end of the ball screw device (next to the machine table), at the far end (such as a central control room), or in a cloud device (in this case, the monitor 17 and the pre-pressure sensing The pieces 16 can be electrically connected to each other through wireless communication). In addition, in some embodiments, the monitor 17 can send the detection signal SS and the pre-pressure value to the cloud device for statistics and analysis of data and signals, so that users can understand the operation of the linear transmission system through these data Happening.

承上，在本實施例的直線傳動系統1a中，使用者可以透過預壓感測件16隨時偵測該些滾動件13a、13b對移動件產生的預壓力，並利用監控器17即時地得知系統的預壓力值，以了解預壓力的調整情況，方便使用者管理或調整，以維持系統精度，避免產生不符合精度要求的加工物件。According to the above, in the linear transmission system 1a of this embodiment, the user can detect the pre-pressure of the rolling elements 13a, 13b on the moving element at any time through the pre-pressure sensing element 16, and use the monitor 17 to obtain in real time Know the pre-pressure value of the system to understand the adjustment of the pre-pressure, which is convenient for users to manage or adjust, so as to maintain the accuracy of the system and avoid processing objects that do not meet the accuracy requirements.

圖7為依據本新型又一實施例之一種直線傳動系統的示意圖，而圖8A與圖8B分別為圖7所示之直線傳動系統的預壓力調整示意圖。7 is a schematic diagram of a linear transmission system according to yet another embodiment of the present invention, and FIGS. 8A and 8B are schematic diagrams of the pre-pressure adjustment of the linear transmission system shown in FIG. 7, respectively.

如圖7與圖8A所示，本實施例的直線傳動系統1b與前述實施例之直線傳動系統1大致相同。與上述實施例主要的不同在於，本實施例的直線傳動系統1b的預壓調整模組15a中，預壓調整器152a（圖8A）為一螺絲，其一側設置於（鎖入）載台本體14面向調整件1511的一側，其另一側包括一錐形側面1521，且錐形側面1521頂抵調整桿1512，並與調整桿1512緊密連接。因此，當使用者發現裝置、系統的剛性或精度降低、或預壓力值偏離原先的設定時（例如精度變差，表示預壓力已偏離原先的值），則可透過轉動預壓調整器152a的方式，將預壓調整器152a往載台本體14（請參考圖8A與圖8B）的方向移動（預壓調整器15的移動方向為方向X，方向X與導引件11的長軸方向平行）。由於預壓調整器152a的錐形側面1521與調整桿1512緊密連接，因此，當預壓調整器152a轉動且更深入載台本體14時（圖8B），將可提供壓迫（推動）調整桿1512的推力（該推力的方向為方向Y，方向Y與導引件11的長軸方向垂直），使調整桿1512遠離調整件1511的另一端往方向Y移動，進而透過轉動調整件1511來調整壓迫螺帽12b外側的力量以調整預壓力值，使滾動件（滾珠）13a、13b對螺帽12a、12b產生的預壓力可以手動調整到例如預定值，藉此達到偏位預壓與手動補償的效果。As shown in FIGS. 7 and 8A, the linear transmission system 1b of this embodiment is substantially the same as the linear transmission system 1 of the foregoing embodiment. The main difference from the above embodiment is that in the preload adjustment module 15a of the linear transmission system 1b of this embodiment, the preload adjuster 152a (FIG. 8A) is a screw, and one side is provided (locked in) on the stage One side of the main body 14 facing the adjusting member 1511 includes a tapered side 1521. The tapered side 1521 abuts the adjusting lever 1512 and is tightly connected to the adjusting lever 1512. Therefore, when the user finds that the rigidity or accuracy of the device or system is reduced, or the pre-pressure value deviates from the original setting (for example, the accuracy deteriorates, indicating that the pre-pressure has deviated from the original value), the user can turn the pre-pressure regulator 152a by turning Method, the preload adjuster 152a is moved in the direction of the stage body 14 (please refer to FIGS. 8A and 8B) (the movement direction of the preload adjuster 15 is the direction X, and the direction X is parallel to the long axis direction of the guide 11 ). Since the tapered side 1521 of the preload adjuster 152a is tightly connected to the adjustment rod 1512, when the preload adjuster 152a rotates and penetrates deeper into the stage body 14 (FIG. 8B), the adjustment (push) adjustment rod 1512 will be provided Thrust (the direction of the thrust is direction Y, which is perpendicular to the long axis of the guide 11), the adjustment rod 1512 is moved away from the other end of the adjustment member 1511 in the direction Y, and the pressure is adjusted by turning the adjustment member 1511 The force on the outside of the nut 12b to adjust the pre-pressure value, so that the pre-pressure generated by the rolling elements (balls) 13a, 13b on the nut 12a, 12b can be manually adjusted to, for example, a predetermined value, thereby achieving offset preload and manual compensation effect.

因此，本實施例之直線傳動系統1b可以在不需拆解裝置的情況下透過預壓調整器152a及預壓組件151來調整滾動件13a、13b與螺帽12a、12b之間的偏位預壓值，藉此，不僅不需要拆解裝置而增加作業時間與成本，對產能的影響也不會太大。Therefore, the linear transmission system 1b of this embodiment can adjust the deflection between the rolling elements 13a, 13b and the nuts 12a, 12b through the preload adjuster 152a and the preload assembly 151 without disassembling the device The pressure value, by this, not only does not need to disassemble the device to increase the operating time and cost, but also has little effect on the production capacity.

此外，前述直線傳動系統1a的預壓感測件16、監控器17也可應用於本實施例的直線傳動系統1b中，具體技術內容可參照上述，在此不再多作說明。In addition, the pre-pressure sensing element 16 and the monitor 17 of the linear transmission system 1a can also be applied to the linear transmission system 1b of this embodiment. For the specific technical content, reference may be made to the above, and no more explanation will be given here.

再說明的是，在圖2的實施例中，如果預壓調整器是穿過固定件153的一螺絲時，當使用者發現裝置、系統的剛性或精度降低、或預壓力值產生偏離時，也可透過轉動螺絲的方式直接對調整桿1512施以較大推力，以提高壓迫（推動）調整桿1512的力量來調整預壓力值，使滾動件（滾珠）13a、13b對螺帽12a、12b產生的預壓力可以手動調整到預定值，同樣也可達到偏位預壓與手動補償的效果。It is further explained that, in the embodiment of FIG. 2, if the preload regulator is a screw passing through the fixing member 153, when the user finds that the rigidity or accuracy of the device or system is reduced, or the preload value deviates, It is also possible to directly apply a large pushing force to the adjusting rod 1512 by turning the screw, so as to increase the force of pressing (pushing) the adjusting rod 1512 to adjust the pre-pressure value, so that the rolling elements (balls) 13a, 13b are opposed to the nuts 12a, 12b The generated pre-pressure can be manually adjusted to a predetermined value, and the effects of offset pre-pressure and manual compensation can also be achieved.

綜上所述，在本新型之直線傳動系統中，移動件滑設於導引件，且導引件相對移動件轉動時，移動件可相對導引件產生直線移動；預壓調整模組設置於移動件，並具有一預壓組件及一預壓調整器；其中，係透過預壓調整器對預壓組件施加一推力，以調整該些滾動件對移動件產生的預壓力值。藉此，使得本新型的直線傳動系統可以在不需拆解裝置的情況下就可透過預壓調整模組的預壓調整器和預壓組件，來調整該些滾動件對移動件所產生的預壓力值，藉此達到偏位預壓與半自動或手動補償的效果。另外，由於本新型不需拆解裝置就可調整偏位預壓值，因此不僅不會增加作業時間與成本，對產能的影響也不會太大。In summary, in the linear transmission system of the present invention, the moving part is slidably disposed on the guide part, and when the guide part rotates relative to the moving part, the moving part can produce a linear movement relative to the guide part; It has a pre-pressure component and a pre-pressure regulator for the moving part; wherein, a pre-pressure regulator is used to apply a pushing force to the pre-pressure component to adjust the pre-pressure value generated by the rolling elements on the moving part. In this way, the linear transmission system of the present invention can adjust the rolling element to the moving element through the preload adjuster and the preload assembly of the preload adjustment module without disassembling the device. Pre-pressure value, to achieve the effect of offset pre-pressure and semi-automatic or manual compensation. In addition, since the new type can adjust the offset preload value without disassembling the device, not only will it not increase the operation time and cost, but it will not affect the production capacity too much.

以上所述僅為舉例性，而非為限制性者。任何未脫離本新型之精神與範疇，而對其進行之等效修改或變更，均應包含於後附之申請專利範圍中。The above is only exemplary, and not restrictive. Any equivalent modifications or changes made without departing from the spirit and scope of this new model should be included in the scope of the attached patent application.
