YK2632數控直齒錐齒輪磨齒機

YK2632 CNC STRAIGHT BEVEL GEAR GRINDER

一．機床用途和使用范圍

本機床用于大量或大批生產條件下磨削直徑320毫米以內模數由1.5到8的直齒錐齒輪。磨齒機磨齒后的齒輪精度可穩定達到GB5級以上。該機床具有較高的加工柔性，良好的動力傳動特性，穩定的運動精度和安全的操作性能，適用于加工精密機械，高精度減速機，精密儀器和高精度部件等中等規格的高精度直齒錐齒輪，能夠顯著提高加工后的齒輪傳動精度及傳動平穩性。

I. MACHINE APPLICATIONS

The machine is designed for grinding straight bevel gears of diameter up to 320mm and module of 1.5 – 8mm in mass production. Accuracy of gears ground on this machine can reach stably to Grade 5 of the GB Standard 。With better machining flexibility, excellent power transmission, stable moving accuracy and safe operating performance, it is suitable to grind middle-sized high precision straight bevel gears used for precision machineries, high precision speed reducers ，accurate instruments & military high precision parts. The transmission accuracy and smoothness of gears ground on this machine will be improved tremendously.

二．機床的主要性能和結構特點

   1．本機床由八個主要部件組成：床身，搖臺，砂輪架，床鞍；工件箱，主驅動，床鞍進給機構，液壓傳動系統。砂輪緊固在砂輪架主軸上，移動砂輪架，砂輪在對工件的一定位置上可調整。工件緊固在裝入工件箱主軸的芯軸上，借助液壓夾緊夾頭緊固。在床鞍上回轉工件箱可實現被加工零件的根錐角，及調整工件箱水平位置來確定工件的輪位。此外，在某些情況下使床鞍對中心位置向前或向后移動滿足床位要求。

   2．機床上裝有砂輪修整裝置。借助兩金剛筆（一支修齒形用，而另一支修砂輪的頂圓）注意所需要的過凹部倒圓半徑的值修整砂輪。

   3．機床還可通過機械機構修正裝置加工鼓形齒頂及齒根修緣。機床能以數控程序自動周期進行工作，此時，除上，下工件外，全部工序都自動進行。

   4．本機床由五個傳動軸組成，并采用德國西門子（SIEMENS）公司的828d數控系統實現（搖臺分度，工件箱分度及床鞍絲杠）3聯動的運動控制，通過人性化磨削軟件包實現機床的自動調整，磨削軟件操作簡單，使用方便。

   5．機床加工齒的一邊，因此加工齒輪的另一面，則可通過旋轉搖臺實現。因為本機床是剛性強，行程快的機床，在機床上可用現代化的磨削規范，并提供紙帶過濾，恒溫油箱（特殊訂貨），吸油霧機等配置。

II. MACHINE FEATURRES

1. The machine consists of the following major components: the machine bed, the cradle, the grinding wheel bracket, the workhead, the main drive, the sliding base feed mechanism and the hydraulic drive ystem. The grinding wheel is fastened on the spindle of the grinding wheel bracket. The grinding wheel position to the workpiece can be adjusted in a certain distance, by moving the grinding wheel bracket. The workpiece is chucked on the arbor which is mounted into the work spindle and fastened by means of a hydraulic chuck. The root angle of the workpiece to be ground can be adjusted by turning the workhead on the sliding base and the workhead setting will be determined by adjusting the horizontal position off the worrkhead. In addition, the sliding base must be moved forward or backward toward the central position under certain circumstances to satisfy the demａnd of the sliding base position.

2. A grinding wheel dresser is equipped on the machine, which has two diamond styluses (One is used for the tooth profile and the other is used for dressing the circumference of the grinding wheel.)

3. Crowned teeth and profile corrected teeth can be ground on this machine by the modifying device of the mechanical mechanism. With the exception of workpiece loading and unloading, all the machine operations are performed automatically in an automatic work cycle.

4. A SIEMENS 828D CNC control system is equipped for the machine, which has 5 drive axes and perform 3-axis simultaneous movements of the cradle indexing, the workhead indexing and the lead screw of the sliding base. Automatic machine setting ups can be made by means of the user-friendly grinding software package, which is of easy operation and convenient use.

5. The machine is designed for grinding one flank of the tooth and the other flank of the tooth can also  be ground rotating the cradle. Therefore, this is a rigid machine with faster grinding cycles. Modern grinding specifications can be adopted on this machine and paper filter, thermostatic oil tank (on special order), oil-mist exhauster, etc. will be available.
