上述结构的磨齿机床虽然能实现齿轮的加工，但是存在以下弊端：首先，现有的磨齿机床结构复杂，零件多，进而导致制造和装配难度大，易出现故障，且出现故障后维修难度大。其次，回转平台4、B轴箱体5、B轴以及砂轮均承载在A轴上，导致A轴承载重量大，不仅使得驱动A轴转动所需的动力更多，而且A轴所需刚性和强度更大，同时，A轴承载重量大会导致稳定性差，进而传动误差大。此外，A轴箱体3、A轴、回转平台4、B轴箱体5、B轴以及砂轮均位于支撑立柱2的同一侧，使得支撑立柱2对应的这一侧承载重量很大，而其它位置重 量较小，进而导致磨齿机床整机稳定性差，传动误差更大。Although the gear grinding machine tool with the above structure can realize the processing of gears, it has the following drawbacks: First, the existing gear grinding machine tool is complex in structure and has many parts, which in turn makes manufacturing and assembling difficult, prone to failure, and difficult to maintain after failure. big. Secondly, the slewing platform 4, the B-axis box 5, the B-axis and the grinding wheel are all carried on the A-axis, resulting in a large load on the A-bearing, which not only makes more power required to drive the A-axis to rotate, but also the rigidity and the rigidity of the A-axis. The strength is greater, and at the same time, the bearing weight of the A bearing will lead to poor stability, and then the transmission error will be large. In addition, the A-axis box 3, A-axis, slewing platform 4, B-axis box 5, B-axis and grinding wheel are all located on the same side of the support column 2, so that the side corresponding to the support column 2 bears a lot of weight, while other The position weight is small, which in turn leads to poor stability of the gear grinding machine and larger transmission error.

Then, compared with the existing gear grinding machine, the gear grinding machine according to the embodiment of the present invention transfers the relevant components required to move in the Y-axis direction to the slide table 200 instead of being arranged on the A-axis of the rotary axis, thereby making the When the A-axis of the rotary axis rotates, the weight required to drive is smaller, which not only makes less power required to drive the A-axis of the rotary axis to rotate, but also requires lower rigidity and strength of the rotary axis A-axis, so that the A-axis of the rotary axis needs to be driven.

At the same time, since the C-axis 600 of the previous workpiece spindle has been moved away from the vicinity of the grinding wheel, the machined gear on the C-axis 600 of the previous workpiece spindle can be removed, and a new gear to be processed can be installed, and then the turntable 800 can be rotated. , the grinding wheel can process the gears in sequence and repeatedly without the need to remove and stop the grinding wheel. The operation is simple, time-saving and labor-saving, and the processing efficiency is high. Finally, the C-axis 600 of the workpiece spindle with the processed gear is removed from the vicinity of the grinding wheel, and then the processed gear is removed and the gear to be processed is installed, so as to avoid accidental touch during the process of removing and assembling the gear. to the grinding wheel and cause a safety accident.
可以理解的是，本实施例中提及到的X轴、Y轴以及Z轴为空间笛卡尔直角坐标系的三个轴，其中X轴和Y轴沿水平方向相互垂直设置，Z轴沿竖直方向设置。此外，本实施例提及的转台800竖直并转动设置于床身100上，是指转台800的轴向为竖直方向，且绕竖直方向的轴心自转。本实施例提及的回转轴箱体400 内设置有平行于X轴方向的回转轴A轴，在齿轮加工机床领域，显而易见，回转轴A轴能够绕自身轴心转动，回转轴A轴平行于X轴方向，是指回转轴A轴的轴向平行于X轴方向。以此类推，砂轮主轴B轴也能够绕自身轴心转动地设置于砂轮箱体500内，且砂轮主轴B轴的轴向垂直于回转轴A轴的轴向。工件主轴C轴600的轴向为竖直方向，且工件主轴C轴600能够绕竖直方向的轴心转动。需要说明的是，回转轴A轴上设置有砂轮箱体500的端部需要延伸于回转轴箱体400外，以便于砂轮箱体500随回转轴A轴转动，砂轮主轴B轴上安装有砂轮的端部需要延伸于砂轮箱体500外，以便于砂轮对工件进行加工，同时以便于砂轮的更换和维修。此外，转台800可以位于第一立柱300对应砂轮的一侧，也就是转台800和砂轮均位于第一立柱300的同一侧。工件主轴C轴600的数量根据实际需求可以是两个或者两个以上。此外，每个工件主轴C轴600外可以套设有C轴箱，以便于保护工件主轴C轴600，当然，工件主轴C轴600的上端同样需要延伸于C轴箱外，以便于安装和更换工件。下面简单阐述本实施例的磨齿机加工齿轮的过程：将待加工齿轮装配于每个工件主轴C轴600上后，控制滑台200沿水平轴向X轴移动至适当位置，控制第一立柱300沿水平轴向Y轴移动至适当位置，控制回转轴箱体400沿竖直轴向Z轴移动至适当位置，并转动转台800，以使砂轮与其中一个齿轮接触，之后转动砂轮主轴B轴，砂轮主轴B轴即可带动砂轮对该齿轮进行磨齿加工，在加工过程中，根据需要，通过适当转动回转轴A轴能够调整砂轮的加工角度，通过适当转动工件主轴C轴600能够调整齿轮的加工部位。加工完该第一个齿轮后，转动转台800，转台800即可带动另外一个工件主轴C轴600上的齿轮移动至砂轮附近，砂轮从而对另外一个工件主轴C轴600上的齿轮进行加工，同时，由于前一个工件主轴C轴600已经从砂轮附近移开，进而可 以将前一个工件主轴C轴600上的已加工好的齿轮取下，并安装新的待加工齿轮，之后再转动转台800，砂轮即可依次并重复不断地对齿轮进行加工。It can be understood that the X-axis, Y-axis and Z-axis mentioned in this embodiment are the three axes of the space Cartesian Cartesian coordinate system, wherein the X-axis and the Y-axis are arranged vertically to each other along the horizontal direction, and the Z-axis is vertically arranged along the vertical direction.

In addition, the turntable 800 mentioned in this embodiment is vertically and rotatably disposed on the bed 100, which means that the axial direction of the turntable 800 is the vertical direction, and rotates around the axis in the vertical direction. The rotary axis box body 400 mentioned in this embodiment is provided with a rotary axis A axis parallel to the X axis direction. In the field of gear processing machine tools, it is obvious that the rotary axis A axis can rotate around its own axis, and the rotary axis A axis is parallel to The X-axis direction means that the axial direction of the rotation axis A-axis is parallel to the X-axis direction. By analogy, the B-axis of the grinding wheel main shaft can also be arranged in the grinding wheel case 500 so as to be rotatable around its own axis, and the axial direction of the B-axis of the grinding wheel main shaft is perpendicular to the axial direction of the rotation axis A-axis. The axial direction of the workpiece spindle C-axis 600 is a vertical direction, and the workpiece spindle C-axis 600 can rotate around the axis in the vertical direction. It should be noted that the end of the rotating shaft A-axis provided with the grinding wheel case 500 needs to extend outside the rotating shaft casing 400, so that the grinding wheel casing 500 rotates with the rotating shaft A, and the grinding wheel is installed on the B-axis of the grinding wheel spindle The end of the grinding wheel needs to extend outside the grinding wheel box 500, so that the grinding wheel can process the workpiece, and at the same time, it is convenient for the replacement and maintenance of the grinding wheel. In addition, the turntable 800 may be located on the side of the first column 300 corresponding to the grinding wheel, that is, the turntable 800 and the grinding wheel are both located on the same side of the first column 300 . The number of the workpiece spindle C-axis 600 may be two or more according to actual requirements. In addition, each workpiece spindle C-axis 600 can be sleeved with a C-axis box to protect the workpiece spindle C-axis 600. Of course, the upper end of the workpiece spindle C-axis 600 also needs to extend outside the C-axis box to facilitate installation and replacement. artifact.
