This drilling adopts crank connecting link and walking beam percussion mechanism, which make the drilling possess two percussive functions, normal drilling takes connecting link impact as main mode, when encountering special situation and the connecting link impact can not drill, it can transform into hoisting impact, the stroke length can be modulated, it realizes automatic percussive drilling due to continuous operating of connecting link percussive mechanism, these can enhance drilling efficiency and relieve labor intensity ; it adopts pumping reverse circulation to drain slag, which not only resolves the drilling difficulty in special stratum such as pebble and gravel stratum and hard stratum, but also resolves the problem that the percussive drill ' s efficiency is low ; it adopts spur gear differential mechanism as double cylinders lazy tongs of main hoist, which not only ensures the balance state of drilling tool, but also reduces the mechanical design, and reduces the cost ; the bottom plate traveling motion of this drilling machine adopts walking type ; the drilling tower adopts hydraulic pressure uprising, and reduces the assistant operating time
該鉆機採用曲柄連桿、游梁式沖擊機構，使鉆機具有兩種沖擊功能;正常鉆進以連桿沖擊為主，遇到特殊情況，用連桿沖擊不能鉆進時，可轉為卷揚沖擊，沖程可調，因連桿沖擊機構連續工作，所以實現了自動沖擊鉆進，可提高鉆進效率，減輕勞動強度;採用泵吸反循環的方式排渣，既能有效解決卵礫石地層、堅硬地層等特殊地層鉆進的困難，又很好地解決了沖擊鉆機效率低下的問題;採用直齒圓柱齒輪差速機構作為主卷揚的雙筒同步機構，既保證了鉆具處于平衡狀態，又大大簡化了該機構設計，降低了成本;該鉆機底盤行走移位採用步履式;鉆塔採用液壓起立，減少了輔助作業時間。 -
The analysis of precision about mould - cut main mechanism with clearances is advanced. on the basis of analysis of slider displacement error influenced by the crank length tolerance, the coupler length tolerance and clearances in revolute joints for mould - cut main mechanism, some reasonable suggestions about tolerance distribution of bars length and fitting precision of joints are put forward
考慮運動副間隙對主切機構進行了精度分析，通過分析主切機構中各桿長誤差和運動副間隙對滑塊位移誤差的影響，對商標模切機設計初期桿長誤差分配和運動副間隙配合精度提出了合理的建議。 -
It is believed, through analyzing, that the ratio radius of the crank to length of the link is importantly influential in the reed motion about 4 - linkage beating - up mechanism, and, that the specific property of slow motion at back center is mainly decided by the second 4 - linkage mechanism on the 6 - linkage beating - up mechanism
對連桿機構運動分析認為：四連桿打緯機構的曲柄半徑與牽手長度之比是影響筘座運動的重要因素，六連桿打緯機構的后心運動緩慢特性主要由第二個四連桿機構決定。 -
This paper deals with the static and dynamic output kinematic accuracy of a group of elastic slider - crank mechanisms with the same design parameters by taking the bar length, joint - gaps, mass density, interception and physical parameters as random variables
摘要將彈性曲柄滑塊機構的桿長、截面尺寸、鉸鏈間隙、質量密度、彈性模量等幾何、物理參數均視為隨機變量，對機構輸出運動進行了靜態和動態誤差分析。 -
Maximize the stitch length, and turn the handwheel until walking foot 1 reaches its front end position. now, loosen screw 2 in the center shaft bell crank
把縫跡調到最大，轉動飛輪，在外壓腳1前進到最前的位置擰松中軸輪緊固螺絲2 。 -
A model of letting out of no oil ubricated double whirlpools vortex air compressor was set up, the length of leak line of one cycle was calculated the change of the leak line at work, the change of the length of leak line varying with the crank corner, and the change of the leak amount varying with the pressure of revealing atmospheric and crank corner were analyzed
摘要建立了無油潤滑雙渦圈渦旋壓縮機的泄露模型，根據型線的幾何理論計算了一個周期內泄漏線的長度，分析了在工作過程中泄漏線的變化，泄漏線長度隨曲柄轉角的變化，以及泄露量隨排氣壓力，曲柄轉角的變代情況。
