Description

液壓量測裝置 Hydraulic measuring device
本發明係關於一種壓力量測裝置,特別是關於一種液壓量測裝置。 The present invention relates to a pressure measuring device, and more particularly to a hydraulic measuring device.
傳統對於液體在衝擊固體表面時,對其所施加壓力的量測方法並未有一個標準化的量測裝置來進行液壓的量測。例如,當鋼材欲進行冷卻處理時,若是冷卻水的水量不是均勻的衝擊在鋼材上時,便會造成冷卻不均,而導致鋼材的機械性質變差。傳統的量測方式是將水杯置於冷卻區下方,藉由比較同樣接水時間內,水杯接水量的多寡,反推冷卻水在鋼材表面衝擊力的大小。然而,這種測量方式並無法精確的計算冷卻水衝擊在鋼材的壓力。 Conventionally, when a liquid is impacting a solid surface, the method of measuring the pressure applied thereto does not have a standardized measuring device for hydraulic measurement. For example, when the steel material is to be subjected to a cooling treatment, if the amount of water of the cooling water is not uniformly impacted on the steel material, uneven cooling is caused, and the mechanical properties of the steel material are deteriorated. The traditional measurement method is to place the water cup under the cooling zone. By comparing the amount of water received by the water cup during the same water receiving time, the impact force of the cooling water on the surface of the steel is reversed. However, this measurement method does not accurately calculate the pressure of the cooling water impact on the steel.
故,有必要提供一種壓力量測裝置,以解決習用技術所存在的問題。 Therefore, it is necessary to provide a pressure measuring device to solve the problems of the conventional technology.

(thermoplastic elastomer, TPE), which can be elastically deformed when pressed, and can be elastically restored to its original shape when the pressure is released.
在本發明一實施例中,該液壓量測裝置10的蓋體18,該蓋體18位於該環繞壁12的開口部121之彈性件17上,因而該蓋體18可上下移動的位於該環繞壁12的開口部121處。該蓋體18具有一內反射面181,該光訊號投射至該內反射面181並形成該反射訊號,其中該蓋體18因應承受一外部液壓而向下位移並抵推該彈性件17造成該彈性件17產生彈性變形;該光接收單元15接收在位移前後之該反射訊號;該訊號處理單元16接收並比較在位移前後之該些反射訊號的一光強度變化差值,以計算產生一液壓參考值。該蓋體18較佳由堅硬之金屬或合金材質製成,且具足夠厚度,因而在受外部液壓作用時不會導致變形。該蓋體18例如係為一剖面呈ㄇ字形的蓋體,且該內反射面181為ㄇ字形蓋體之一內頂面,並由該內反射面181抵接該彈性件17。在蓋上該蓋體10後,該液壓量測裝置10之容置空間122除上述元件外僅填充有常壓的空氣或惰性氣體(如氮氣),並不包含任何液體。 In an embodiment of the present invention, the cover 18 of the hydraulic measuring device 10 is located on the elastic member 17 of the opening portion 121 of the surrounding wall 12, so that the cover 18 can be moved up and down. At the opening 121 of the wall 12. The cover 18 has an internal reflection surface 181, and the optical signal is projected to the internal reflection surface 181 to form the reflection signal. The cover 18 is downwardly displaced by an external hydraulic pressure and pushes the elastic member 17 to cause the reflection. The elastic member 17 is elastically deformed; the light receiving unit 15 receives the reflected signal before and after the displacement; the signal processing unit 16 receives and compares a light intensity variation difference of the reflected signals before and after the displacement to calculate a hydraulic pressure. Reference. The cover 18 is preferably made of a hard metal or alloy material and has a sufficient thickness so as not to cause deformation when subjected to external hydraulic pressure. The cover body 18 is, for example, a cover body having a U-shaped cross section, and the inner reflection surface 181 is an inner top surface of the U-shaped cover body, and the inner reflection surface 181 abuts against the elastic member 17. After the cover 10 is covered, the accommodating space 122 of the hydraulic measuring device 10 is filled with only atmospheric air or an inert gas (such as nitrogen) except for the above components, and does not contain any liquid.
以下將詳細說明本發明一實施例之液壓量測裝置10的使用。首先,可先將該液壓量測裝置10設置在欲量測液壓的位置,例如在一欲冷卻的鋼材上。在一實施例中,可以設置多個液壓量測裝置10於鋼材的不同位置處上,以量側位在各個位置處的液壓。該液壓量測裝置10量測液壓的方式可以是如下方的描述來實現。接著,當該發光單元14發出一光訊號後,該光訊號會受到該蓋體18的阻擋改變路徑,進而反射以形成一反射訊號。該光接收單元15接收該反射訊號,並交由該訊號處理單元16進行處理分析。另外,可以理解的是,若是該蓋體18的位置改變時,則該光訊號受到該蓋體18的阻擋進而反射所形成的該反射訊號的路徑將會改變,因而使得該光接收單元15所接收的該反射訊號的強度改變。舉例而言,若是該蓋體18受到來自上方的液壓而朝下移動時,該蓋體18的內反射面181也會朝下移動,其中該蓋體18下 移的幅度會與該液壓的大小有正相關,因為該蓋體18與該環繞壁12之間的該彈性件17可提供與該液壓相抗衡的反向力。綜上觀之,該光接收單元15所接收該反射訊號的強度,會與該蓋體所承受的液壓產生相關性。 The use of the hydraulic measuring device 10 of one embodiment of the present invention will be described in detail below. First, the hydraulic measuring device 10 can be first placed at a position where the hydraulic pressure is to be measured, for example, on a steel material to be cooled. In one embodiment, a plurality of hydraulic measuring devices 10 may be provided at different locations of the steel material to measure the hydraulic pressure at the various locations. The manner in which the hydraulic measuring device 10 measures the hydraulic pressure may be implemented as described below. Then, when the light emitting unit 14 emits an optical signal, the optical signal is blocked by the cover 18 and is reflected to form a reflected signal. The light receiving unit 15 receives the reflected signal and sends it to the signal processing unit 16 for processing analysis. In addition, it can be understood that if the position of the cover 18 is changed, the path of the reflected signal formed by the optical signal being blocked by the cover 18 and reflected by the cover 18 will be changed, thereby causing the light receiving unit 15 to The intensity of the received reflected signal changes. For example, if the cover 18 is moved downward by the hydraulic pressure from above, the inner reflection surface 181 of the cover 18 also moves downward, wherein the cover 18 is lowered. The magnitude of the displacement will be positively correlated with the magnitude of the hydraulic pressure because the resilient member 17 between the cover 18 and the surrounding wall 12 provides a counter force that counteracts the hydraulic pressure. In summary, the intensity of the reflected signal received by the light receiving unit 15 may be related to the hydraulic pressure that the cover is subjected to.
續言之,上述的相關性可透過數據統計來比較壓力大小的相對關係,例如當液壓越大使得該蓋體18偏離原本位置越多,則該光接收單元15所接收該反射訊號的強度越小,此可提供使用者一種定性上的測量;或是可透過物理推導計算出一精確公式來計算壓力的精確量值,例如考慮該蓋體18的尺寸/質量、該彈性件17的彈力係數、該發光單元14的位置及光訊號的發出強度等等。 In other words, the above correlation can compare the relative relationship of the pressure magnitudes through data statistics. For example, the greater the hydraulic pressure, the more the cover body 18 is offset from the original position, the more the intensity of the reflected signal received by the light receiving unit 15 is. Small, this can provide a qualitative measurement by the user; or an accurate formula can be calculated by physical derivation to calculate the exact magnitude of the pressure, for example considering the size/mass of the cover 18 and the elastic coefficient of the elastic member 17. The position of the light-emitting unit 14 and the emission intensity of the optical signal, and the like.
綜上所述,本發明實施例之液壓量測裝置係利用光線移動路徑的改變來測量液體衝擊到蓋體的壓力,故可精確計算在液壓量測裝置外部之液體壓力。 In summary, the hydraulic measuring device of the embodiment of the present invention uses the change of the light moving path to measure the pressure of the liquid impinging on the cover body, so that the liquid pressure outside the hydraulic measuring device can be accurately calculated.
