就像每次都在用同一個測頭測針進(jìn)行測量一樣。經(jīng)過在同一標(biāo)準(zhǔn)球（未更換過空間位置的）上標(biāo)定過的測頭，都能準(zhǔn)確地實現(xiàn)這種自動轉(zhuǎn)換功能，這種自動轉(zhuǎn)換的功能為測量帶來了極大的便利。2:標(biāo)定直徑在實際測量過程中，不難發(fā)現(xiàn)存在測頭測針標(biāo)定后的“標(biāo)定值”小于名義值的現(xiàn)象，但是該現(xiàn)象不會影響測量機(jī)的測量準(zhǔn)確度。相反，還會對觸測信號的延時和測針的微小形變產(chǎn)生補(bǔ)償作用。在坐標(biāo)測量機(jī)測量過程中，測量系統(tǒng)會對測頭測針紅寶石球半徑進(jìn)行修正（即上文提到把測針紅寶石球球心坐標(biāo)換算到觸測點的空間坐標(biāo)），這種修正使用的是“標(biāo)定直徑"而不是“名義直徑”。該現(xiàn)象產(chǎn)生的原因有以下3個方面：（1）觸發(fā)式的測頭在原理上相當(dāng)于杠桿結(jié)構(gòu)。點接觸測量時，必須使測頭的傳感器能夠觸發(fā)才能發(fā)出信號。由于測針（相當(dāng)于力臂）有一定的長度，所以在測針的寶石球接觸到標(biāo)準(zhǔn)球后，還要運(yùn)行一段距離，才能觸發(fā)傳感器，測針越長，這段距離就越大。因此導(dǎo)致觸發(fā)信號有一定的延遲，使擬合球的直徑小于測針寶石球直徑和標(biāo)準(zhǔn)球直徑之和。測量時把擬合球的直徑減去標(biāo)準(zhǔn)球的實際校準(zhǔn)直徑后，得到的標(biāo)定后測頭測針直徑的標(biāo)定值小于其名義值。（2）測頭測針在點接觸式測量過程中。重慶雷尼紹測頭測頭測頭的性價比、質(zhì)量？</p><div

測頭是三坐標(biāo)測量機(jī)的重要部分，一般的測頭是由一個桿和紅寶石球組成，主要用來測量工作表面，通過測端的機(jī)械位置移動，觸發(fā)信號并采集一個測量數(shù)據(jù)。可見測頭的性能直接影響測量精度和測量效率。觸發(fā)式測頭結(jié)構(gòu)簡單、成本低，可用于高速測量，所以廣泛應(yīng)用于現(xiàn)代三坐標(biāo)測量機(jī)中。但由于其精度稍低，而且不能以接觸狀態(tài)停留在工件表面，因而只能對工件表面作離散的逐點測量，不能作連續(xù)的掃描測量。常用觸發(fā)式測頭內(nèi)部結(jié)構(gòu)如圖1所示。測桿安裝在三角架上，而三角架的三條圓柱腿定位于三對觸點上，當(dāng)測桿沒有受到測量力時，三角架的三條圓柱腿與三對觸點均保持接觸；當(dāng)測桿的球狀端部與工件接觸時，不論受到X、Y、Z哪個方向的接觸力，至少會引起一個圓柱腿與觸點脫離接觸，從而引起電路的斷開，產(chǎn)生階躍信號，通過采樣電路，將沿三個軸方向的坐標(biāo)數(shù)據(jù)存儲處理。同時一個與測桿同軸的彈簧提供預(yù)載，以測頭凸角存在的原因是觸發(fā)式測頭的三點設(shè)計原則，當(dāng)作用給測端一個特定方向的力時，可能會產(chǎn)生繞一個或兩個接觸點的旋轉(zhuǎn)，導(dǎo)致所需確保圓柱腿與觸點的接觸及復(fù)位。因此這種測頭具有信號觸發(fā)的開關(guān)機(jī)構(gòu)、測頭再定位機(jī)構(gòu)和超行程保護(hù)機(jī)構(gòu)。三坐標(biāo)測量機(jī)進(jìn)行測量時。</p><p> 對于需要嚴(yán)格定位和定向測量的場合，掃描探頭在離散點的測量方面也具有優(yōu)勢:1、在可以應(yīng)用接觸式測頭的情況下，慎選非接觸式測頭;2、在只測尺寸、位置要素的情況下盡量選接觸式觸發(fā)測頭;3、考慮成本又能滿足要求的情況下，盡量選接觸式觸發(fā)測頭:4、對形狀及輪廓精度要求較高的情況下選用掃描測頭;5、掃描測頭應(yīng)當(dāng)可以對離散點進(jìn)行測量:6、考慮掃描測頭與觸發(fā)測頭的互換性(一般用通用測座來達(dá)到);7、易變形零件、精度不高零件、要求超大量數(shù)據(jù)零件的測量，可以考慮采用非接觸式測頭;8、要考慮軟件、附加硬件(如測頭控制器、電纜)的配套。3.掃描測頭的優(yōu)勢及劣勢優(yōu)勢:1、適于形狀及輪廓測量:.2、采點率高:.3、高密度采點保證了良好的重復(fù)性、再現(xiàn)性(GR&R):4、更高級的數(shù)據(jù)處理能力:劣勢:.1、比觸發(fā)測頭復(fù)雜:2、對離散點的測量較觸發(fā)測頭為慢:3、高速掃描時由于加速度而引起的動態(tài)誤差很大，不可忽略，必須加以補(bǔ)償;4、測尖的磨損必須注意。4.觸發(fā)式測頭的優(yōu)勢及劣勢:優(yōu)勢:1、適于空間棱柱形物體及己知表面的測量:2、通用性強(qiáng),3、有多種不同類型的觸發(fā)測頭及附件供采用:4、采購及運(yùn)行成本低;5、應(yīng)用簡單6、適用于尺寸測量及在線應(yīng)用:7、堅固耐用8、體積小。測頭的性能是怎么樣的？</p><div

***個觸發(fā)式測頭于1972年由英國Renishaw公司研制。觸發(fā)式測頭的測量原理是當(dāng)測頭測端與被測工件接觸時精密量儀發(fā)出采樣脈沖信號，并通過儀器的定位系統(tǒng)鎖存此時測端球心的坐標(biāo)值，以此來確定測端與被測工件接觸點的坐標(biāo)。該類測頭具有結(jié)構(gòu)簡單、使用方便、制作成本低及較高觸發(fā)精度等優(yōu)點，是三維測頭中應(yīng)用*****的測頭。但該類測頭也存在各向異性（三角效應(yīng)）、預(yù)行程等誤差，限制了其測量精度的進(jìn)一步提高，**高精度只能達(dá)零點幾微米。在精密量儀上采用觸發(fā)式測頭進(jìn)行測量時，通常是兩點定線、三點定面、三點或四點定圓等方法，其實質(zhì)是用幾個點的坐標(biāo)來確定理想幾何要素的尺寸大小，而在形位誤差測量方面就顯示出明顯缺陷；掃描測頭的出現(xiàn)彌補(bǔ)了觸發(fā)式測頭這方面的不足。掃描式測頭也稱量化測頭，測頭輸出量與測頭偏移量成正比，作為一種精度高、功能強(qiáng)、適應(yīng)性廣的測頭，同時具備空間坐標(biāo)點的位置探測和曲線曲面的掃描測量的功能。該類測頭的測量原理是測頭測端在接觸被測工件后，連續(xù)測得接觸位移，測頭的轉(zhuǎn)換裝置輸出與測桿的微小偏移成正比的信號，該信號和精密量儀的相應(yīng)坐標(biāo)值疊加便可得到被測工件上點的精確坐標(biāo)。若不考慮測桿的變形，掃描式測頭是各向同性的。哪家的測頭開始降價了？河北RMP60測頭測頭</p><p

故其精度遠(yuǎn)遠(yuǎn)高于觸發(fā)式測頭。該類測頭的缺點是結(jié)構(gòu)復(fù)雜，制造成本高，目前世界上只有少數(shù)公司可以生產(chǎn)。各類精密測頭的現(xiàn)狀觸發(fā)式測頭當(dāng)觸發(fā)式測頭的測端觸碰到被測工件時，測頭發(fā)出觸發(fā)信號。其**是判斷接觸與否，類似電子開關(guān)的工作性質(zhì)，故又稱開關(guān)測頭。實現(xiàn)此功能的方法有電子機(jī)械開關(guān)的通斷、壓電晶體的壓電效應(yīng)和應(yīng)變片的形變等。早期的觸發(fā)式測頭采用彈簧力作用下的機(jī)械定位機(jī)構(gòu)，如圖1所示，當(dāng)測端與被測工件接觸時，產(chǎn)生的接觸力由測桿傳遞至測頭體內(nèi)部的觸發(fā)機(jī)構(gòu)，當(dāng)該力增大到足以克服內(nèi)部彈簧的預(yù)壓力時，觸發(fā)機(jī)構(gòu)的機(jī)械觸點便脫離接觸，進(jìn)而發(fā)出觸發(fā)信號。采用此方式觸發(fā)的測頭存在以下弊端：當(dāng)測頭從不同方向觸測工件時，克服內(nèi)部彈簧所需的接觸力并不相同，這就導(dǎo)致了測頭從不同方向觸測工件時測頭的預(yù)行程也不同，降低了重復(fù)性精度。這是引起測量誤差的**大誤差源，而該設(shè)計方式根本無法避免預(yù)行程的變化。另外，測頭測端與被測工件接觸時，測桿由于受力會發(fā)生彎曲變形，同樣會引入測量誤差，且該誤差隨著測桿的長度增加而增加。Renishaw公司早期的觸發(fā)式測頭TP2，只能支持10mm長的測桿，預(yù)行程變化量為，單向重復(fù)性精度為。重慶雷尼紹測頭測頭</p><p
