三、  工作原理

III. Working Principle

1、機(jī)械部分

1. Mechanical Part

雙端面磨平機(jī),雙面磨平機(jī) 工作臺(tái)的往復(fù)由電機(jī)帶動(dòng)變速箱，輸出慢速帶動(dòng)絲桿工作，作逆旋轉(zhuǎn)，絲桿螺母固定在工作臺(tái)下面，從而帶動(dòng)工作臺(tái)作往復(fù)移動(dòng)。

The motor drives the transmission to output low speed to drive the screw rod to work in reverse rotation. In this way, the to-and-fro movement of work bench of double-end grinding machine (double-face grinding machine) is realized. Screw rod nuts are fixed under work bench to drive the bench move back and forth.

本機(jī)磨頭是專業(yè)金剛石磨輪，直接安裝在兩臺(tái)專用電機(jī)上，分別由兩個(gè)橫向工作臺(tái)帶動(dòng)前進(jìn)或后退，既可以自動(dòng)，又可以手動(dòng)。自動(dòng)時(shí)將手柄向前推。手動(dòng)時(shí)，將手柄向后拉即可。絲杠每一轉(zhuǎn)為3MM。

This machine uses dedicated diamond grinding wheel directly mounted the two special-purpose motors that are respectively driven by the two horizontal bench, manually or automatically. In auto mode, the handle shall be pushed forward. In case of manual mode, the handle shall be drawn back. Every round of screw rod is 3mm.

工作臺(tái)的標(biāo)本夾具和兩磨輪在本設(shè)備出廠前，經(jīng)過精心調(diào)試，確保磨出的標(biāo)本的垂直度與平行度。每次磨削兩個(gè)平行面，六個(gè)面的立方體標(biāo)本，只需要經(jīng)過三次磨削成即可，每次要定位準(zhǔn)確，這樣磨出的試樣才能達(dá)到要求。

Before leaving the factory, the sample fixture and two grinding wheels of work bench has been carefully debugged so as to ensure that the perpendicularity and parallelism of processed sample. Cubic samples with two parallel surfaces and six faces need only three times of grinding. For each grinding, the sample shall be accurately positioned. Only in this way, can the processed sample meet the requirements.

2、電器部分

2. Electric section

電氣控制見電器原理圖

See electrical principle diagram for electric control

雙端面磨平機(jī),雙面磨平機(jī)控制的按鈕分別安裝在兩個(gè)動(dòng)力頭上面，操作方便。因采用水冷卻，水花飛濺，故本機(jī)電器采用36V的安全電壓。由于電源電壓、運(yùn)行電機(jī)電壓380V，所以本機(jī)必須進(jìn)行可靠的接地，否則會(huì)產(chǎn)生安全事故。故電源不能接反，否則會(huì)損壞機(jī)器。

The buttons of double-end grinding machine (double-face grinding machine) are respectively mounted on the two power heads for convenient operation. Since water cooling may cause water splash, this equipment uses 36V safety voltage. This machine must be reliably grounded as the power supply voltage for motor is 308V; otherwise, safety accidents may occur. The power supply connection shall not be reverse since this may cause damage to the machine.
