三、主要結(jié)構(gòu)說明

Main Structure

本機(jī)結(jié)構(gòu)主要由三套磨頭、離盒器、研缽支座、及定位器等總裝組成。

The structure of such machine is as shown in Figure to Figure. See Figure for its overall structure which is mainly composed of three sets of grinding heads, clutch, mortar support, localizer, etc.

磨頭、研體支座和離合器互成120°均勻地安裝在轉(zhuǎn)座上,轉(zhuǎn)座的軸承中,在底座正面裝有接料支板及電器,左方裝有電機(jī)。當(dāng)離合器接通時(shí),電機(jī)通過皮帶輪,齒輪軸,萬向節(jié)帶動(dòng)磨頭旋轉(zhuǎn)。齒輪軸的另一頭和研缽支座的齒輪嚙合。由于研棒的正轉(zhuǎn)和研缽的同向自轉(zhuǎn)產(chǎn)生相對(duì)滑動(dòng),借磨頭的自重產(chǎn)生壓力磨細(xì)物料。

Grinding head, mortar support and clutch are evenly installed on the rotating seat and in the bearing of rotating seat, at an angle of 120°between each two of them. On the front of the base are mounted receiving support plate and electrical equipment; on its left is installed a motor. When the clutches are connected, the motor drives the rotation of the grinding head through the belt pulley, gear shaft, and cardan joint. The other end of gear shaft and the gear of mortar supportengage. Since relative sliding occurs due to clockwise rotation of grinding bar and clockwise rotation of mortar, the materials are grinded through the weight of grinding head.

離合器是常閉干式磨擦離合器。

See Figure for clutch which is normally closed dry friction clutch.

磨擦離合器的結(jié)合和脫開是靠杠桿繞支釘?shù)纳舷聰[動(dòng)實(shí)現(xiàn)的,杠桿上抬時(shí),彈簧被壓縮,磨擦片與齒輪脫開。杠桿下移時(shí),彈簧復(fù)位,磨擦片與齒輪端面貼面貼合,從而傳遞動(dòng)力。

The matching and separation of friction clutch are realized through the up-and-down movement of lever around the support pin. When the lever is lifted up, the spring is compressed and the friction plate and gear are separated. When the lever is lowered down, the spring returns to its original position, and the friction plate matches the end face of gear so as to be able to transfer power.

杠桿的上下移動(dòng)靠操縱手柄實(shí)現(xiàn)。手柄在圖示右邊時(shí),離合器貼合,逆時(shí)針旋轉(zhuǎn)到左邊時(shí),裝在轉(zhuǎn)盤里的軸靠偏心作用推動(dòng)銷子,頂起杠桿的調(diào)節(jié)螺絲,杠桿向上擺動(dòng),將離合器脫開。在使用過程中,當(dāng)磨擦損時(shí),可松開螺帽,向下調(diào)節(jié)調(diào)整螺絲。

The up and down movement of lever is realized through the control handle. When the handle is on the right as is shown in the figure, the clutches match and rotate to the left counterclockwise. The shaft in the rotating disk drives the dowel through eccentric action and jack up the adjusting screw of lever, the lever upswings and separates the clutch. In case of damage by rubbing during the application process, loosen the nuts and adjust the screws downward.

由于每一對(duì)研具都有單獨(dú)的離合器操作,因此三對(duì)研具的運(yùn)動(dòng)互不影響,即可同時(shí)工作,也可使其中一對(duì)或二對(duì)工作。

As every pair of lapper is equipped with independent clutch, the three pairs of lappers move independently of each other. That is to say, all of them can operate simultaneously or operate in one pair and two pairs.

磨頭結(jié)構(gòu)見,當(dāng)動(dòng)力由離合器萬向節(jié)傳來時(shí),由錐齒輪軸,錐齒輪帶動(dòng)軸旋轉(zhuǎn),由于偏心作用,軸帶動(dòng)軸承座及其上的研棒座,研棒繞軸作旋轉(zhuǎn)運(yùn)動(dòng)。

See Figure for the structure of grinding head. When the power is transmitted from the cardan joint of clutch, the bevel gear shaft and bevel gear drive the rotation of shafts. Under eccentric action, the shafts drive the bearing pedestal and the grinding bar base above it. The grinding bar revolves around the shaft.

磨頭壓力的調(diào)節(jié)是靠調(diào)節(jié)盤簧的松緊來實(shí)現(xiàn)的。

The pressure of grinding head is adjusted through the adjustment of the tension of the coil spring.

由于旋轉(zhuǎn)臂兩側(cè)裝有兩根軸,這兩根軸分別裝在軸承座的軸承上,固定在座蓋,因此旋轉(zhuǎn)臂可繞軸的軸心線旋轉(zhuǎn),為了調(diào)整磨頭壓力,在左右軸承座的外側(cè)均裝有一根盤簧它的一端上,另一端卡在軸上。當(dāng)松開半園頭螺釘,如果朝著研磨中心離開方向旋轉(zhuǎn)蓋,則盤簧收緊,磨頭的壓力可適當(dāng)減少,反之,則磨頭的壓力可適當(dāng)增加。用戶可根據(jù)不同研磨對(duì)象自行調(diào)整,出廠時(shí)盤簧調(diào)整到減輕磨頭壓力的狀態(tài)。

Since on the two sides of the rotary arm are two shafts which are installed on the bearings of bearing pedestal and fixed on the seat cover, the rotary arm can revolve around the axis line of shafts. To adjust the pressure of grinding head, on the outside of the left and right bearing pedestals coil spring is added to one end of it. The other end of it is clipped on the shaft If it moves toward the grinding center to leave the swiveling cover when the half round screws are loosened, the coil spring tightens up. The pressure of grinding pressure can be reduced properly. Otherwise, the pressure of grinding pressure can be increased properly. The user can adjust its pressure according to the grinding object. When it is ready for shipment, the coil spring shall be adjusted to the condition of reduced grinding head pressure.

研缽支座的結(jié)構(gòu),當(dāng)動(dòng)力由齒輪傳來時(shí),摩擦輪帶動(dòng)摩擦環(huán),從而使研缽旋轉(zhuǎn)。另外軸承座通過軸鉸接于研缽支座橫孔中,當(dāng)抬起磨頭,取下缽罩,操縱手柄,則研缽隨同軸承座繞軸旋轉(zhuǎn),以便倒也已磨好的物料。

See Figure for the structure of mortar support. When the power is transmitted from the gear, the friction wheel drives the friction ring so as to get the mortar to rotate. In addition, the bearing pedestal is hinged to the cross-drilled holes of mortar support through shafts. When the grinding head is lifted up, and the mortar cover and the control handle are dismounted, the mortar revolves around the shaft along with the bearing pedestal (03-1), to handle the already grinded materials.

定位器的結(jié)構(gòu),輕輕按一下手柄套,軸承座從轉(zhuǎn)盤的定位槽中退出,以便換位,當(dāng)轉(zhuǎn)盤轉(zhuǎn)到所需位置時(shí),軸承座嵌入轉(zhuǎn)盤槽中實(shí)現(xiàn)換位。

See Figure for the structure of localizer. Press the handle sleeve gently and the bearing pedestal gets out of the locating slot of the rotating disk to change position. When the rotating disk rotates to the required position, the bearing pedestal is embedded into the locating slot of the rotation disk to realize change of position.

平時(shí)操作者一般坐在設(shè)備正面接料架處,操縱開關(guān),離合器手柄和定位手柄即可對(duì)三對(duì)研具依次進(jìn)行操作。

Generally, the operator sits on the receiving material shelf on the front of the equipment. The three pairs of lappers can be operated in sequence if the switch, clutch handle, and locating handle are controlled.

為了適應(yīng)磨細(xì)多種物料的要求,三對(duì)研具間設(shè)有隔板,以防樣品互相混雜。

To grind various kinds of materials, clapboards are installed among the three pairs of lappers to avoid mixing of samples.
