Description

一种数控磨齿机 技术领域
本发明涉及一种齿轮加工机床，特别涉及一种数控磨齿机。
背景技术
数控磨齿机用于高速、精确地磨削圆柱直、斜齿轮，其目的是修整齿轮热处理后的变形，提高齿面精度以及光洁度，达到传动平稳、降低噪音以及提高精度的要求。
现有的数控磨齿机床，如图1和图2所示，设置有机身1，机身1上沿水平轴向X轴移动设置有支撑立柱2，支撑立柱2上沿竖直轴向Z轴移动设置有A轴箱体3，A轴箱体3上转动设置有平行于X轴方向的A轴，A轴上固定设置有回转平台4，回转平台4上沿水平轴向Y轴移动设置有B轴箱体5，B轴箱体5内转动设置有平行于Y轴方向的B轴，B轴的一端设置有用于加工工件的砂轮。机身1上竖直并转动设置有C轴6，C轴6位于支撑立柱2对应砂轮的一侧，C轴6的上端用于安装工件。
上述结构的数控磨齿机床虽然能实现齿轮的加工，但是存在以下弊端：首先，现有的数控磨齿机床结构复杂，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，进而导致A轴尺寸更大，同时，A轴承载重量大会导致稳定性差，进而传动误差更大。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，传动误差大。
发明内容
本发明旨在至少解决现有技术中存在的技术问题之一。为此，本发明提出一种数控磨齿机，不仅零件少，结构简单，而且回转轴A轴承载的重量小，进而回转轴A轴自身所需刚性和强度更低，此外，磨齿机整机稳定性好，传动误差小。

下面参考图3至图7描述根据本发明实施例的数控磨齿机。
根据本发明实施例的数控磨齿机，如图3至图7所示，包括床身100、滑台200以及工件主轴C轴600，滑台200沿水平轴向X轴移动设置于床身100上，滑台200上沿水平轴向Y轴移动设置有第一立柱300，第一立柱300于自身移动方向的一侧沿竖直轴向Z轴移动设置有回转轴箱体400，回转轴箱体400内设置有平行于X轴方向的回转轴A轴，回转轴A轴的端部设置有砂轮箱体500，砂轮箱体500内设置有垂直于回转轴A轴的砂轮主轴B轴，砂轮主轴B轴的端部安装有砂轮，工件主轴C轴600竖直设置于床身100上，且位于第一立柱300对应砂轮的一侧，工件主轴C轴600的上端用于安装工件。
本实施例中，齿轮的加工取决于砂轮和工件的相对位置，而砂轮与工件的相对位置可以通过床身100与滑台200的相对位置、滑台200与第一立柱300的相对位置、第一立柱300与回转轴箱体400的相对位置以及回转轴A轴、砂轮主轴B轴、工件主轴C轴600转动的角度来确定，即需要加工齿轮时，移动滑台200、第一立柱300以及回转轴箱体400，并转动回转轴A轴、砂轮主轴B轴以及工件主轴C轴600，即可调整齿轮加工时的加工部位、进给量以及加工角度，从而加工出所需齿轮。本发明实施例的数控磨齿机，首先，相比于现有的数控磨齿机床，结构更加简单，零件更少，进而使得制造和装配难度更低，加工更加准确，加工精度更高，从而更加不容易出现故障，且出现故障后维修难度更低。然后，由于本发明实施例的数控磨齿机结构更加简单，零件更少，进而使得结构更加紧凑，占地面积更小。其次，相比于现有的数控磨齿机床，本发明实施例的数控磨齿机将沿Y轴方向移动所需的相关部件转移到了滑台200上，而不是设置在回转轴A轴上，进而使得回转轴A轴转动时所需驱动的重量更小，不仅使得驱动回转轴A轴转动所需的动力更少，而且回转轴A轴的刚性和强度要求更低，从而使得回转轴A轴所需尺寸更小，对应的，回转轴箱体400以及第一立柱300所需尺寸更小，同时A轴承载重量小会导致稳定性好，进而传动误差小。此外，砂轮旋转中心距离回转轴A轴更近，回转轴A轴承受的挠度更小，抖动更小，进而结构强度更高且传动更加平稳。最后，本发明实施例减少了第一立柱300上靠近回转轴箱体400的一侧的部件和重量，使第一立柱稳定性更好，进而使得磨齿机床整机稳定性更好，传动误差更小
需要说明的是，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。可以理解的是，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轴也是绕自身轴心转动设置于砂轮箱体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绕竖直方向的轴心转动。此外，工件主轴C轴600位于第一立柱300对应砂轮的一侧，也就是工件主轴C轴600和砂轮均位于第一立柱300的同一侧。此外，回转轴A轴设置有砂轮箱体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，可以预见的是，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数控磨齿机加工齿轮的过程：将待加工齿轮装配于工件主轴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，以使砂轮与齿轮接触，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位置。
在本发明的一些实施例中，如图3至图5以及图7所示，床身100上设置有第二立柱700，第二立柱700上可升降地设置有顶持部701，顶持部701位于工件主轴C轴600的上方。当齿轮安装在工件主轴C轴600上后，将顶持部701朝下移动，使顶持部701顶持齿轮的上端面，从而防止齿轮在加工的过程中发生偏移或者掉落。顶持部701可升降地设置在第二立柱700上，可以是在第二立柱700上沿竖直方向设置有滑轨，顶持部701滑动设置在滑轨上，第二立柱700上可以设置有连接顶持部701的电机丝杆机构、气缸或者油缸等驱动装置，通过驱动装置即可控制顶持部701沿滑轨上下移动，从而实现顶持部701的升降。当然，也可以不设置滑轨，而是驱动装置直接控制顶持部701上下移动。顶持部701可以是顶尖套。
在本发明的一些实施例中，床身100上设置有上下料机构，上下料机构用于将工件搬运至工件主轴C轴600上或者从工件主轴C轴600上移除。上下料机构能够将 待加工齿轮搬运至工件主轴C轴600上进行加工，或者将已经加工好的齿轮从工件主轴C轴600上移除，而不需要人工进行操作，操作更加简单，自动化程度更高，更加省时省力，而且能够减少安全事故的发生。
在本发明的一些实施例中，如图3至图7所示，上下料机构包括套设于第二立柱700外侧的回转套筒801、设置于回转套筒801上的机械夹爪802以及用于控制回转套筒801绕自身轴心转动的驱动部803，机械夹爪802于回转套筒801转动的过程中能够移动至工件主轴C轴600的上方或者从工件主轴C轴600的上方移开。回转套筒801的一侧可以设置有放置平台，放置平台用于放置待加工齿轮和已经加工好的齿轮，具体的，启动驱动部803，驱动部803控制回转套筒801转动，回转套筒801带动机械夹爪802转动，当机械夹爪802转动至待加工齿轮处时，机械夹爪802夹持待加工齿轮，然后驱动部803控制回转套筒801继续转动，回转套筒801进而带动机械夹爪802转动至工件主轴C轴600的正上方，之后松开机械夹爪802，待加工齿轮即可安装至工件主轴C轴600上，然后控制顶持部701下降使顶持部701顶持待加工齿轮的上端面即可。当需要将已经加工好的齿轮从工件主轴C轴600上移除时，控制顶持部701上升使顶持部701与已经加工好的齿轮分离，之后驱动部803控制回转套筒801转动，回转套筒801带动机械夹爪802转动至工件主轴C轴600上方对应齿轮的位置，机械夹爪802夹持已经加工好的齿轮，然后驱动部803控制回转套筒801继续转动，回转套筒801进而带动机械夹爪802转动至放置平台上，之后松开机械夹爪802即可将已经加工好的齿轮移到放置平台对应的位置上，操作更加简单，自动化程度更高，更加省时省力，而且能够减少安全事故的发生。此外，上下料机构也可是以通过机器人来进行搬运。可以理解的是，第二立柱700对应回转套筒801的部位的外侧壁可以是外圆柱面，回转套筒801的内侧壁可以是与第二立柱700的外侧壁相适配的内圆柱面，进而便于回转套筒801转动。
在本发明的一些实施例中，如图3至图7所示，回转套筒801的外侧壁上设置有外齿圈804，驱动部803包括设置于第二立柱700上的驱动电机806以及设置于驱动电机806输出端上的传动齿轮805，传动齿轮805与外齿圈804啮合。启动驱动电机806，驱动电机806带动传动齿轮805转动，由于传动齿轮805与外齿圈804啮合，传动齿轮805进而能够带动回转套筒801转动。传动齿轮805与外齿圈804啮合，也就是驱动电机806通过齿轮传动机构来驱动回转套筒801转动，齿轮传动机构不仅传动平稳，而且通过设置齿轮的传动比还可以调节回转套筒801的转动速度。当然，回转套筒801也可 以是通过电机直接进行驱动。
在本发明的一些实施例中，如图3、图5、图6和图7所示，机械夹爪802不少于两个并沿回转套筒801的周向依次设置。机械夹爪802可以是两个、三个或者三个以上，以机械夹爪802为两个时为例，两个机械夹爪802可以设置于回转套筒801相对的外侧壁上，放置平台可以设置于回转套筒801背离工件主轴C轴600的一侧，进而当第一个机械夹爪802从工件主轴C轴600上抓取已经加工好的齿轮时，第二个机械夹爪802刚好能够从放置平台上抓取未加工齿轮，之后回转套筒801转动半圈，第一个机械夹爪802刚好将已经加工好的齿轮放置于放置平台上并从放置平台上抓取新的未加工齿轮，而第二个机械夹爪802刚好将前一个未加工的齿轮安装至工件主轴C轴600上，重复前面步骤，即可快速加工齿轮。机械夹爪802设置为不少于两个，加工效率更高，更加省时省力。
在本发明的一些实施例中，如图3至图7所示，数控磨齿机还包括砂轮修整器900，砂轮修整器900用于对砂轮进行修整。砂轮在使用一段时间后需要修整，砂轮修整器900能够直接对砂轮进行修整，而不需要将砂轮拆下送至其它地方进行修整，快捷方便。
在本发明的一些实施例中，砂轮修整器900设置于床身100上并位于砂轮箱体500的下方或者设置于第一立柱300上并位于砂轮箱体500的上方或者设置于回转套筒801上。砂轮修整器900可以设置在三个位置，第一个位置如图3所示，设置于第一立柱300与工件主轴C轴600之间的床身100上，并位于砂轮箱体500的下方，此种情况下，砂轮修整器900距离离砂轮较近，进而修整砂轮时更加方便，此外，安装砂轮修整器900也更加方便。第二个位置如图7所示，设置于砂轮箱体500上方的第一立柱300上，具体的，第一立柱300上沿竖直方向设置有滑轨，砂轮修整器900滑动设置在滑轨上，进而砂轮修整器900能够进行升降，使得修整砂轮时更加方便，而且修整精度更高。第三个位置是回转套筒801上，砂轮修整器900随回转套筒801来回转动，同样能够实现对砂轮进行修整。
在本发明的一些实施例中，床身100上或者第一立柱300上或者回转套筒801上竖直并转动设置有摆动轴，砂轮修整器900设置于所述摆动轴上。砂轮修整器900包括设置于摆动轴上的驱动电机以及设置于驱动电机的输出轴上的砂轮修整头，驱动电机的输出轴水平设置，摆动轴通过自身转动能够调整砂轮修整器900的修整角度，不仅使砂轮修整器900修整更加方便，而且修整精度更高。
在本发明的一些实施例中，床身100上设置有X轴导轨，滑台200滑动设置于X 轴导轨上，滑台200上设置有Y轴导轨，第一立柱300滑动设置于Y轴导轨上，第一立柱300上设置有Z轴导轨，回转轴箱体400滑动设置于Z轴导轨上。设置X轴导轨、Y轴导轨以及Z轴导轨，能够确保滑台200、第一立柱300以及回转轴箱体400沿设定方向移动，进而能够减少加工误差。可以理解的是，X轴导轨的长度方向为水平轴向X轴方向，Y轴导轨的长度方向为水平轴向Y轴方向，Z轴导轨的长度方向为竖直轴向Z轴方向。
在本发明的一些实施例中，数控磨齿机还包括第一驱动机构、第二驱动机构以及第三驱动机构，第一驱动机构设置于床身100上并传动连接滑台200，以用于控制滑台200沿X轴导轨滑动；第二驱动机构设置于滑台200上并传动连接第一立柱300，以用于控制第一立柱300沿Y轴导轨滑动；第三驱动机构设置于第一立柱300上并传动连接回转轴箱体400，以用于控制回转轴箱体400沿Z轴导轨滑动。通过第一驱动机构、第二驱动机构以及第三驱动机构，能够实现滑台200、第一立柱300以及回转轴箱体400位置的调整，进而实现砂轮和工件位置的调整。
在本发明的一些实施例中，第一驱动机构、第二驱动机构以及第三驱动机构均为电机丝杆机构。具体的，电机丝杆机构包括电机、丝杆以及螺母，以第一驱动机构为例，电机设置在床身100上，丝杆与电机的输出轴连接，螺母固定设置在滑台200上，丝杆与螺母螺纹连接，当电机带动丝杆转动时，丝杆即可带动螺母移动，螺母即可带动滑台200移动。电机丝杆机构传动平稳，调节准确。此外，第一驱动机构、第二驱动机构以及第三驱动机构也可以是气缸、油缸或者直线电机等。
在本发明的一些实施例中，床身100内于工件主轴C轴600的下方设置有内置式电机，内置式电机的输出轴与工件主轴C轴600连接。内置式电机直接与工件主轴C轴600连接，相比现有的电机通过传动机构与工件主轴C轴600连接，能够减少传动机构传动带来的误差，进而使得加工更加准确。此外，回转轴A轴和砂轮主轴B轴也均可以通过内置式电机直接驱动。内置式电机可以是伺服电机，进而能够进行无级调速。
在本发明的一些实施例中，如图3、图4和图7所示，第一立柱300靠近回转轴箱体400的一侧向下延伸至滑台200的底端。第一立柱300的底端与延伸至滑台200底端的延伸部围合形成一个安装腔301，滑台200位于安装腔301内，滑台200的顶端可以设置有导轨，安装腔301的顶端也就是第一立柱300的底端可以对应设置有滑槽，第一立柱300通过导轨与滑槽的配合滑动安装在滑台200上。第一立柱300靠 近回转轴箱体400的一侧向下延伸至滑台200的底端，进而回转轴箱体400可以移动至滑台200的底端也就是靠近床身100的位置，进而回转轴箱体400移动的范围更大，加工齿轮时更加方便。滑台200位于安装腔301内，不仅能够防止滑台200直接暴露在外而积聚灰尘或者遭到损坏，而且能够降低第一立柱300的重心，此外能够使整机结构更加紧凑，稳定性更好。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
