雕刻機主軸問題判斷

  在雕刻加工過程中木匠開料機的雕刻主軸所承受的作业任務很重,作业頻率很高,所以也是最簡略出現問題的部位之一。一般来說,出現以下这幾種动靜是可以判别出問題的:

  一、淅瀝淅瀝的动靜

  由堅持器與翻滾體振动、沖突發生,不管潤滑脂種類怎樣都能夠發生,承受力矩、負荷或徑向遊隙大的時分更簡略發生。

  解決方法:前進堅持器精度、選用遊隙小的軸承或對軸承施加預負荷、下降力矩負荷,減少設備過失、選用好的油脂。

  二、嗡嗡的动靜

  馬达無負荷作业是宣告類似蜂鳴相同的动靜,且馬达發生軸向失常振动,開或關機時有嗡嗡聲。

  解決方法:多呈現在潤滑狀況欠好,以及在冬天且兩端用球軸承的馬达,主要是軸調心功能欠好時,軸向振动影響下發生的一種不穩定的振动。

  三、雜質音

  由軸承或優質的清潔度導致,宣告一種不規則的失常音,动靜時有時無,時大時小,在高速電機上發生頻頻

  解決方法:選用好的油脂、前進注脂前的清潔度、加強軸承的密封功能、前進設備環境的清潔度

  四、哒哒的动靜

  动靜頻率随軸承轉速而改动,零件表面波紋度是導致噪音的主要原因

  解決方法:改善軸承滾道表面加工質量,下降波紋度幅值、減少碰傷、修改遊隙預緊力和協作,檢查安閑端軸承的作业,改善軸與軸承座的精度設備方法。

  这就是木匠開料機在加工過程中通常會發出来的一些动靜,關于这些不同的动靜,我們要做出正确的判别,然後依據問題而加以解決,終究到达抱負的加工效果

  In carving process, carpenter's cutting machine's main task is very heavy and the operation frequency is very high, so it's also one of the most simple problems. Generally speaking, the following problems can be identified as follows:

  A movement, patter

  The vibration and conflict of the attachment and tumbling body can happen regardless of the type of grease. It can happen more easily, and it will take more time to bear the moment, load or radial clearance.

  The way to solve this problem is to advance the precision of the stick, select the bearing with small clearance or load the load on the bearing, and reduce the torque load, so as to reduce the equipment fault and the grease selected.

  Two, buzzing

  The motor load free operation is the same as the bee sounding, and the motor has an axially abnormal vibration, and there is a buzzing sound when opening or closing the machine.

  The way of solution is that the unstable vibration occurs mostly when the motor is lubricated and the ball bearings are used at both ends of the winter, which is mainly influenced by axial vibration.

  Three. The sound of impurity

  It is caused by the cleanliness of the bearing or high quality, announces an irregular sound of aberration, which is sometimes no, when it is small, and occurs frequently on the high speed motor.

  The solution: select good grease, advance the cleanliness, strengthen the sealing function of the bearing, and the cleanliness of the advance equipment environment

  Four, Dada movement

  The dynamic and static frequency changes with the bearing speed, and the surface ripple of the part is the main cause of noise.

  The solution is to improve the processing quality of bearing raceway surface, reduce the amplitude of corrugation, reduce the bruise, modify the clearance and preload and cooperate, check the operation of the idle end bearing, and improve the accuracy and equipment of shaft and bearing seat.

  This is the movement of a carpenter's opening machine during the processing. For these different movements, we should make the correct judgement and solve it according to the problem, and finally achieve the desired processing effect.
