導(dǎo)軌絲杠出現(xiàn)故障問題都是很常見的問題，但也是可以避免的，關(guān)鍵是要看導(dǎo)軌的保養(yǎng)工作，有時還必須考慮到導(dǎo)軌的組成元件，例如保持架的材質(zhì)、形式印設(shè)計與工藝因素，也與導(dǎo)軌內(nèi)部的滑動摩擦，潤滑劑的貯存與維持，滾動體運轉(zhuǎn)的穩(wěn)定性等息息相關(guān)。

The failure of the guide rail lead screw is a common problem, but it can also be avoided. The key is to see the maintenance of the guide rail. Sometimes, it is also necessary to consider the components of the guide rail, such as the material of the cage, the design of the form print and the process factors, and it is also closely related to the sliding friction inside the guide rail, the storage and maintenance of the lubricant, and the stability of the rolling element operation.

1、電動機(jī)過熱報警的修補(bǔ)

1. Repair of motor overheat alarm

缺陷現(xiàn)象：X軸電動機(jī)過熱報警剖析及處理進(jìn)程：電動機(jī)過熱報警，發(fā)生的原因有多種，除伺服單元本身的問題外，或許是切削參數(shù)不合理，亦或許是傳動鏈上有問題。而該機(jī)床的缺陷原因是由于直線導(dǎo)軌鑲條與導(dǎo)軌空位太小，調(diào)得太緊。松開鑲條防松螺釘，調(diào)整鑲條螺栓，使運動部件運動活絡(luò)，確保0.03mm的塞尺不得塞入，然后鎖緊防松螺釘。缺陷清掃。

Defect phenomenon: X-axis motor overheat alarm analysis and processing process: The motor overheat alarm occurs for a variety of reasons. In addition to the problem of the servo unit itself, it may be that the cutting parameters are unreasonable, or there may be a problem on the transmission chain. The reason for the defect of the machine tool is that the gap between the linear guide rail insert and the guide rail is too small and too tight. Loosen the insert lock screw, adjust the insert bolt, make the moving parts move flexibly, ensure that the 0.03mm feeler gauge cannot be inserted, and then lock the lock screw. Defect cleaning.

2、行程終端發(fā)生顯著的機(jī)械振動缺陷修補(bǔ)

2. Repair of significant mechanical vibration defects at the end of travel

缺陷現(xiàn)象：某加工作業(yè)時，作業(yè)臺X軸方向位移挨近行程終端進(jìn)程中發(fā)生顯著的機(jī)械振動缺陷，缺陷發(fā)生時體系不報警。

Defect phenomenon: during the operation of a machining center, the X-axis displacement of the worktable is close to the end of the stroke, and a significant mechanical vibration defect occurs. When the defect occurs, the system will not alarm.

剖析及處理進(jìn)程：因缺陷發(fā)生時體系不報警，但缺陷顯著，故經(jīng)過交換法查看，供認(rèn)缺陷部位應(yīng)在X軸伺服電動機(jī)與絲杠傳動鏈一側(cè)。為差異電動機(jī)缺陷，可折卸電動機(jī)與滾珠絲杠之間的彈性聯(lián)軸器，獨自通電查看電動機(jī)。

Analysis and processing process: because the system does not alarm when the defect occurs, but the defect is significant, so through the exchange method, the admitted defect position should be at the side of the X-axis servo motor and the lead screw drive chain. In order to distinguish the defects of the motor, the elastic coupling between the motor and the ball screw can be removed, and the motor can be checked by powering on alone.

查看結(jié)果表明，電動機(jī)作業(yè)時無振動現(xiàn)象，顯著缺陷部位在機(jī)械傳動部分。脫開彈性聯(lián)軸器，用扳手翻滾滾珠絲杠進(jìn)行手感查看;經(jīng)過手感查看，發(fā)現(xiàn)作業(yè)臺X軸方向位移挨近行程終端時，感覺到阻力顯著增加。拆下作業(yè)臺查看，發(fā)現(xiàn)滾珠絲杠與導(dǎo)軌不平行，故而引起機(jī)械翻滾進(jìn)程中的振動現(xiàn)象。經(jīng)過細(xì)心修補(bǔ)、調(diào)整后，從頭裝好，缺陷清掃。

The inspection results show that there is no vibration during the operation of the motor, and the obvious defect is in the mechanical transmission part. Disengage the elastic coupling and roll the ball screw with a wrench to check the handle; Through hand feeling inspection, it is found that the resistance increases significantly when the displacement of the X-axis direction of the workbench approaches the end of the stroke. Dismantle the worktable and check it. It is found that the ball screw is not parallel to the guide rail, which causes vibration in the process of mechanical rolling. After careful repair and adjustment, install from the beginning and clean the defects.

3、滾珠絲杠螺母松動引起的缺陷修補(bǔ)

3. Defect repair caused by loose ball screw nut

缺陷現(xiàn)象：機(jī)床Z軸作業(yè)(方滑枕為Z軸)哆嗦，瞬間即呈現(xiàn)123號報警;機(jī)床間斷作業(yè)。剖析及處理進(jìn)程：呈現(xiàn)123號報警的原因是盯梢過失超出了機(jī)床數(shù)TEN345/N346中所規(guī)則的值導(dǎo)致此種現(xiàn)象有三個或許：

Defect phenomenon: the machine tool Z axis operation (the square ram is Z axis) trembles, and the 123 alarm will appear immediately; The machine tool operates intermittently. Analysis and processing process: The reason for the 123 alarm is that the tracking error exceeds the value specified in the machine tool number TEN345/N346, which leads to three possible reasons:

①方位測量體系的檢測器材與機(jī)械位移部分聯(lián)接不良。

① The detection equipment of the azimuth measurement system is not well connected with the mechanical displacement part.

②傳動部分呈現(xiàn)空位。

② The transmission part is empty.

③方位閉環(huán)放大系數(shù)KV不匹配。

③ The azimuth closed-loop amplification factor KV does not match.

注意，使用前后要細(xì)心擦凈導(dǎo)軌和絲杠表面的油污，特別是溝槽里的油污，要注意導(dǎo)軌安裝孔內(nèi)的油污。用油脂槍嘴在注油油嘴往傳動腔內(nèi)部加油，直內(nèi)部污油全部被擠出。被擠出的污油。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://www.2b4g.com咨詢吧！

Attention: before and after use, carefully clean the oil stain on the guide rail and the lead screw surface, especially the oil stain in the groove, and pay attention to the oil stain in the guide rail installation hole. Use the grease gun nozzle to add oil to the inside of the transmission cavity at the oil nozzle until all the dirty oil inside is squeezed out. Remove the squeezed dirty oil.
