Description

磨床及其控制方法 技术领域
本发明涉及磨床技术领域，具体提供一种磨床以及磨床的控制方法。
背景技术
磨床是对硬脆材料进行磨削加工的设备。如磨床通常包括上料上料装置、进给滑台装置以及磨削装置。以硬脆材料为硅棒为例，如首先将开方后的硅棒固定至上料装置，在对硅棒所处的位置和姿态进行初步调节后，将硅棒送达至进给滑台装置的两个夹头之间，如两个夹头可以均为动夹头，或者两个夹头中的一个为动夹头而另一个为定夹头。通过硅棒的轴向运动，将硅棒送达对应于磨削装置的位置，基于此，便可对硅棒的其中一组待磨削面进行相应的磨削加工。之后，通过使硅棒旋转，从而转动至第二组待磨削面，基于此便对该第二组待磨削面进行相应的磨削加工。
磨削加工主要包括在先的粗磨作业和在后的精磨作业，相应地，磨削装置主要包括负责粗磨作业的粗磨砂轮和负责精磨作业的精磨砂轮。如前所述对于同一组磨削面而言，需要配置一对的粗磨砂轮一对精磨砂轮，加之粗磨砂轮和精磨砂轮还需要分别配置两个驱动传动机构，一个为用于实现粗/精磨砂轮靠近/远离硅棒的驱动传动机构(移动)，另一个为用于实现粗/精磨砂轮对硅棒进行磨削的驱动传动机构(转动)，这将导致磨削装置相对磨床整体在体积上具有相当的占比。由于对应于的粗磨砂轮和精磨砂轮的运动形式以及作业顺序具有相当的关联性，因此，如何针对二者在空间上的布置进行整合，尚存一定的提升空间。
发明内容
为了至少一定程度地解决上述技术问题，提出本发明。具体而言，如何在尽可能地保证磨削功能仍能够实现的前提下实现磨削装置的结构的紧凑化，是本发明要解决的技术问题。
在第一方面，本发明提供了一种磨床，该磨床包括：1)固定基座；2)横梁滑台组件，其包括：横梁，其能够相对所述固定基座滑动；以及滑台，其能够相对所述横梁滑动；3)磨削组件，其包括：粗磨砂轮；以及精磨砂轮；其中，所述精磨砂轮和所述粗磨砂轮中的其中一个形成有沿其轴向分布的预留空间，所述精磨砂轮和所述粗磨砂轮中的另一个的至少一部分能够容纳于所述预留空间，以便：在 所述精磨砂轮和所述粗磨砂轮中的一个处于工作状态的情形下，所述精磨砂轮和所述粗磨砂轮中的另一个的靠近待加工件的端部容纳于所述预留空间并因此不干涉所述粗磨砂轮的磨削作业；其中，所述磨削组件固定设置于所述滑台。
通过这样的构成，能够谋求通过将粗磨砂轮和精磨砂轮进行空间上的整合的方式，使得磨削组件的结构更为紧凑。由于节省了粗磨砂轮和精磨砂轮转换所需的时间，因此能够有效地提高磨削效率。
可以理解的是，本领域技术人员可以根据实际需求确定粗磨砂轮和精磨砂轮之间的相对位置，如可以是粗磨砂轮在外精磨砂轮在内，也可以是精磨砂轮在外而粗磨砂轮在内。
可以理解的是，本领域技术人员可以根据实际需求确定预留空间的构造方式以及位于径向内侧的精/粗磨砂轮如何实现其相对预留空间的位置变化。以粗磨砂轮位于径向内侧为例，如除了精磨砂轮自身中部与预留空间相适配的第一部分“掏空”，还包括与精磨砂轮相关联的部件的第二部分“掏空”，或者该第二部分“掏空”可以通过额外增设的部件形成或者二者的结合(额外增设的部件和与精磨砂轮相关联的部件相结合)形成等。
仍以粗磨砂轮位于径向内侧为例，此外，可以理解的是，本领域技术人员可以根据实际需求确定粗磨砂轮在处于非工作状态时(无法磨削待加工件的位置)的位置状态。如在粗磨砂轮处于非工作状态期间，其可以处于某一固定的位置或者可以处于可选的某几个位置之一。示例性地，沿轴向相对精磨砂轮的位置设定有三个，第一位置为与精磨砂轮的端面大致对齐的位置、第二位置为相对精磨砂轮的端面略缩回的位置、第三位置为相对精磨砂轮的端面明显缩回的位置。如在频繁使用磨床期间，可以使粗磨砂轮处于非工作状态期间位于第二位置或者第三位置，在磨床处于生产阶段和使用阶段的期间或者是当前作业中的最后一次粗磨作业结束的情形下，可以使粗磨砂轮位于第一位置。
在一种可能的实施方式中，所述磨削组件包括：粗磨砂轮以及精磨砂轮；其中，所述精磨砂轮形成有沿其轴向分布的预留空间，所述粗磨砂轮的至少一部分能够容纳于所述预留空间，以便：在所述粗磨砂轮处于工作状态的情形下，所述粗磨砂轮能够以靠近待加工件的方式对待加工件进行磨削作业，并且所述精磨砂轮靠近待加工件的端部容纳于所述预留空间并因此不干涉所述粗磨砂轮的磨削作业。
在一种可能的实施方式中，所述磨削组件包括：粗磨砂轮；以及精磨砂轮；其中，所述精磨砂轮和所述粗磨砂轮中的其中一个形成有沿其轴向分布的预 留空间，所述精磨砂轮和所述粗磨砂轮中的另一个的至少一部分能够容纳于所述预留空间；所述磨削组件还包括：第一驱动部件，其能够驱动所述精磨砂轮和/或所述粗磨砂轮转动以进行相应的磨削作业；以及第二驱动部件，其能够驱动所述精磨砂轮和所述粗磨砂轮中的另一个靠近待加工件的端部容纳于所述预留空间。
在一种可能的实施方式中，所述磨削组件包括：粗磨砂轮；以及精磨砂轮；其中，所述精磨砂轮和所述粗磨砂轮中的其中一个形成有沿其轴向分布的预留空间，所述精磨砂轮和所述粗磨砂轮中的另一个的至少一部分能够容纳于所述预留空间，以便：在所述精磨砂轮和所述粗磨砂轮中的一个处于工作状态的情形下，所述精磨砂轮和所述粗磨砂轮中的另一个的靠近待加工件的端部容纳于所述预留空间并因此不干涉所述粗磨砂轮的磨削作业；所述磨削组件还包括：第一驱动部件，其能够驱动所述精磨砂轮和/或所述粗磨砂轮转动以进行相应的磨削作业；并且所述第一驱动部件的至少一部分以不暴露于环境的方式设置于形成所述磨削组件。
在一种可能的实施方式中，所述磨削装置包括：1)磨削组件，其包括：粗磨砂轮；以及精磨砂轮；其中，所述精磨砂轮和所述粗磨砂轮中的其中一个形成有沿其轴向分布的预留空间，所述精磨砂轮和所述粗磨砂轮中的另一个的至少一部分能够容纳于所述预留空间，以便：在所述精磨砂轮和所述粗磨砂轮中的一个处于工作状态的情形下，所述精磨砂轮和所述粗磨砂轮中的另一个的靠近待加工件的端部容纳于所述预留空间并因此不干涉所述粗磨砂轮的磨削作业；2)检测组件，其配置于磨削组件，并且所述检测组件能够与所述磨削组件同步向靠近/远离待加工件的方向移动；以及所述检测组件能够相对所述磨削组件向靠近/远离待加工件的方向移动。
对于上述磨削组件，在一种可能的实施方式中，所述第二驱动部件以带传动的方式与所述第二传动轴驱动连接。
通过这样的构成，给出了第二驱动部件与第二传动轴之间实现驱动连接的另一种可能的结构形式。可以理解的是，本领域技术人员可以根据实际需求选择任意可行的带传动的具体形式。
在第二方面，本发明还提供一种磨床的控制方法，其特征在于，所述磨床包括固定基座、横梁滑台组件和磨削组件，其中，所述精磨砂轮和所述粗磨砂轮中的其中一个形成有沿其轴向分布的预留空间，所述精磨砂轮和所述粗磨砂轮中的另一个的至少一部分能够容纳于所述预留空间，所述控制方法包括：使所述横梁滑台组件的横梁相对所述固定基座滑动，以使得所述磨削组件沿待加工件的轴向运动；并且/或者使所述滑台相对所述横梁滑动，以使得固定设置于所述滑台的所述磨 削组件以靠近/远离待加工件的方式运动；并且/或者使所述精磨砂轮和/或所述粗磨砂轮转动，以使得处于工作状态的精磨砂轮或者所述粗磨砂轮能够进行相应的磨削作业；并且/或者使至少一部分容纳于所述预留空间的所述精磨砂轮或者所述粗磨砂轮以靠近/远离待加工件的方式运动，以便：使所述精磨砂轮和所述粗磨砂轮中的一个处于工作状态，并且在所述精磨砂轮和所述粗磨砂轮中的一个处于工作状态的情形下，所述精磨砂轮和所述粗磨砂轮中的另一个不干涉其磨削作业。

如图1至图9所示，图1示出本发明一种实施例的磨床的结构示意图一；图2示出本发明一种实施例的磨床的结构示意图二；图3示出本发明第一种实施例的磨床的磨削装置的结构示意图；图4示出本发明一种实施例的磨床的横梁滑台的结构示意图；图5示出本发明一种实施例的磨床的磨削组件的剖视示意图；图6示出本发明一种实施例的磨床的磨削组件的结构示意图一；图7示出本发明一种实施例的磨床的磨削组件的结构示意图二；图8示出本发明另一种实施例的磨床的磨削组件的结构示意图；图9示出本发明一种实施例的磨床的检测组件的结构示意图。下文将参照图1至图9中的全部或者部分来阐述本发明。
磨床主要用于将作为待加工件的、开方后的硅棒磨削加工至设定的规格。具体而言，理想状态下，开方后的硅棒通常是宽度和高度相等的长方体。但在实际中，开方后的硅棒的表面并不平整，如通常情形下表现为：硅棒的中间部分较之于两端部分凸起，硅棒的出刀口尺寸大于入刀口尺寸(金刚线切出端面的正方形的边长大于金刚线切入端面的正方形的边长)。因此，需要通过磨床将开方后的硅棒磨削至标准规格的理想长方体。
主要参照图1至图4，在一种可能的实施方式中，立式磨床100主要包括固定基座1、磨削装置3和横梁滑台4。其中，磨削装置3主要包括一对相向设置的用于对硅棒2进行磨削作业的磨削组件31以及一对在磨削作业之前对硅棒的位置和姿态进行检测的检测组件32。其中，磨削组件包括用于对硅棒进行精磨作业的精磨砂轮311以及用于对硅棒进行粗磨作业的粗磨砂轮312。
在一种可能的实施方式中，竖向设置的固定基座1上设置有上夹紧座和下夹紧座，其中，上夹紧座可沿竖直方向活动(如可称作动夹头11)，下夹紧座相对固定地设置于固定基座(如可称作定夹头12)，动夹头配置有动夹头驱动电机111以驱动动夹头沿竖直方向移动，从而与定夹头配合将硅棒夹紧，定夹头还起到支撑硅棒底部的作用。其中，动夹头还设置有动夹头旋转电机112以带动硅棒进行旋转，从而实现硅棒的旋转。定夹头可以设置定夹头旋转电机121也可以不设置，在设置定夹头旋转电机的情形下，能够保证硅棒2从一组磨削面旋转到另一组磨削面的旋转过程更加稳定。
在一种可能的实施方式中，横梁滑台4主要包括横梁41以及与两组磨削装置对应的两个滑台组件42，其中，横梁41的上下侧设置有滑轨411，滑台组件42包括滑板421以及滑板驱动部件422(如电缸)，滑板的上下两侧具有能够与滑轨配合的滑槽。这样一来，在滑板驱动部件的驱动作用下，滑台通过滑槽与滑轨之间的配合沿横梁滑动。基于这一滑动，下文中所说的检测组件中的探针便可靠近硅棒从而在磨削作业前检测硅棒的位置和姿态，粗/精磨砂轮便可靠近硅棒从而对硅棒进行粗磨作业或者精磨作业。
与横梁滑台4相适配，固定基座1在靠近两侧的部分设置有两组竖向的滑槽14，与两组磨削组件对应的两个横梁固定座13借助于相应侧的滑槽(如横梁固定座的相应侧设置有与滑槽配合的滑块)沿竖直方向移动。横梁滑台中的横梁41固定在横梁固定座13上，从而伴随着一对横梁滑台座相对固定基座的上下滑动带动一对磨削组件沿竖直方向移动。这样一来，左右两侧的两个磨削组件可以以同步上、下移动的方式对硅棒的一对磨削面进行磨削作业。
在一种可能的实施方式中，精磨砂轮311和粗磨砂轮312以同心设置的方式处于同一个工位，并且粗磨砂轮自由容纳于精磨砂轮内部形成的预留空间内。在本示例中，一对磨削组件和一对检测组件在横梁滑台4上对称设置(位于硅棒的两侧)并能够以靠近/远离硅棒的方向相对横梁滑台滑动。这样一来，便可使得磨削组件在同一个工位实现对硅棒的精磨和粗磨作业。
主要参照图5至图7，在一种可能的实施方式中，磨削组件31还包括复合轴，复合轴包括筒状结构的第一传动轴3131(轴套)和容纳于所述筒状结构内的第二传动轴3132，其中，轴套与精磨砂轮连接以便在轴套转动的情形下带动精磨砂轮连接，第二传动轴与粗磨砂轮连接以便在第二传动轴转动的情形下带动粗磨砂轮连接。
基于该复合轴，磨削组件实现其磨削作业的原理是：在需要对硅棒进行粗磨作业的情形下，使第二传动轴沿其轴向运动从而使得粗磨砂轮沿伸出精磨砂轮。并结合磨削组件沿横梁滑台的移动，便可使得粗磨砂轮到达磨削位，从而通过使第二传动轴转动带动粗磨砂轮转动。而在需要对硅棒进行精磨作业的情形下，通过第二传动轴的伸缩运动使得粗磨砂轮处于不干涉精磨砂轮的位置。基于此，结合磨削组件沿横梁滑台的移动，便可使得精磨砂轮到达磨削位，从而通过使第一传动轴转动带动粗磨砂轮转动。
参照前述的描述可知，其中的精磨作业的实现需要包含第一传动轴的转动、滑台相对横梁的横向滑动以及横梁固定座相对固定基座的竖向滑动。其中的粗磨作业的实现需要包含第二传动轴的伸缩运动、第二传动轴的转动、滑台相对横梁的横向滑动以及横梁固定座相对固定基座的竖向滑动。
在一种可能的实施方式中，第一传动轴和第二传动轴始终保持同步转动。相应地，磨削组件31包括第一驱动部件314，如第一驱动部件为驱动电机，通过第一驱动部件与第一传动轴和第二传动轴构成的复合轴同时驱动连接。
在一种可能的实施方式中，磨削组件31包括安装基体315，安装基体和第一转动轴的外壁之间形成安装空间，第一驱动部件容纳于该安装空间内并与第一传动轴的外壁直接驱动连接。可以看出，这样的电机内置的设置方式使得磨削组件的结构更为紧凑。
可以理解的是，本领域技术人员可以根据实际需求确定安装空间的具体构造方式、结构形式及其相对复合轴的位置，如可以靠近中部或者端部的位置等。此外，可以理解的是，可选地，也可以将第一驱动部件设置为外置的部件，如可以通过外置(如设置于复合轴尾端或者沿径向的侧部)的电机、气动马达或液压马达 等驱动复合轴实现其旋转运动。
在一种可能的实施方式中，磨削组件31包括第二驱动部件316，如第二驱动部件为驱动电机，通过第二驱动部件使得第二传动轴相对第一传动轴沿其轴向的伸缩运动。
在一种可能的实施方式中，磨削组件包括丝杠螺母副51，第二驱动部件的输出轴与丝杠螺母副的丝杠连接，第二传动轴上设置有旋转支撑部件，如旋转支撑部件可以为轴套、轴承、轴承箱等，在本示例中，旋转支撑部件为轴承箱52，轴承箱和丝杠螺母副的螺母之间设置有连接座53，连接座配置有直线导轨54。这样一来，第二驱动部件转动带动丝杠转动，伴随着与螺母固接的连接座在直线导轨内的滑动，与连接座和第二传动轴均固接的轴承箱将的带动第二传动轴在第一传动轴内的伸缩运动。
可以理解的是，除了前述的驱动电机和丝杠螺母副的配合，也可以采用如滑台气缸/电缸/液压缸等其他方式实现。此外，与伸缩部分相关的第二驱动部件可以设置于复合轴的任意位置，如可以是本示例中的径向外侧或者也可以设置于复合轴的尾端端等其他位置。
主要参照图7，在一种可能的实施方式中，安装基体315大致为一个壳状结构(如称作主轴体壳)，除了用于与第一传动轴配合形成安装空间，也同时作为如第二驱动部件、丝杠螺母副、直线导轨以及连接座等结构的载体。
主要参照图8，在另一种可能的实施方式中，第二驱动部件316为电机，电机通过带轮机构55与复合轴的后端相连并因此带动第一传动轴3131和第二传动轴3132同步转动。基于此，主要为对应于粗磨砂轮312的第二传动轴配置一个可实现其伸缩的机构，便可实现粗磨作业和精磨作业的切换。具体而言，在需要对硅棒进行粗磨作业的情形下将其相对精磨砂轮311伸出，而在需要对硅棒进行精磨作业的情形下将其相对精磨砂轮缩回(预留空间)即可。
示例性地，实现粗磨作业和精磨作业的切换一种方式为：伸缩机构包括弹簧，第二传动轴在弹簧的预紧力的作用下处于相对精磨砂轮缩回的状态。这样一来，在需要对硅棒进行精磨作业的情形下，保持无外力施加的状态即可。而在需要对硅棒进行粗磨作业的情形下，通过向弹簧施加外力的方式从而使得与之相关联的粗磨砂轮伸出精磨砂轮。如可以通过动力缸、直线模组或者能够实现伸缩运动的驱动传动机构等外力机构对顶住轴承箱后端的压盖施加外力，从而使得弹簧在该外力的作用下发生形变并因此使得粗磨砂轮伸出。显然本领域技术人员可以根据实际需求采用其他合理的、同样可实现切换的结构或者机构等。
除了前述的电机与包含丝杠螺母副/带传动组合的传动方式，本领域技术人员还可以根据实际需求采用其他合理的驱动传动方式来实现第二传动轴的伸缩运动，如电机与齿轮齿条机构的组合、动力缸直接驱动、直线模组的直线驱动等。
此外，在本示例中，磨削组件在靠近粗磨砂轮和精磨砂轮的端部配置有喷水组件61、喷气组件62以及挡水毛刷63，其中，喷水组件61能够向粗磨砂轮或者精磨砂轮喷冷却水从而对粗磨砂轮或者精磨砂轮降温，喷气组件62能够向粗磨砂轮或者精磨砂轮吹出压缩空气从而将磨削后的硅棒表面的水渍吹干，如这样的操作便于探针在一组磨削作业完成后对硅棒进行准确的检测作业。挡水毛刷主要用于隔离在磨削作业的过程中产生的硅粉以及与前述的喷水/喷气组件相关的水汽。可以看出，安装基体315同样也是喷水组件61、喷气组件62和挡水毛刷63的载体。
在本实施例中，内侧的第二传动轴在远离粗磨砂轮的一端(尾端)具有始终伸出第一传动轴的伸出部分，伸出部分通过轴承箱(如变径轴承套)与连接座连接，这样一来，在保证伸缩运动得以可靠地实现的前提下，为第二传动轴提供了强大的磨削承载力。
这样一来，在磨削作业期间，第二传动轴的支撑力与磨削反力所形成的力偶由直线导轨承载，基于此，在能为第二传动轴的轴向伸缩运动提供精确的导向作用的同时，还减少了位于第二传动轴的尾端的轴承箱的承载力，因此保证了磨削精度、磨削可靠性，增加了磨削组件的使用寿命周期。
主要参照图5，在一种可能的实施方式中，在粗磨砂轮处于工作状态的情形下，粗磨砂轮的磨头伸出并凸出精磨砂轮外圆精磨面基准面第一轴向距离X，如理论上X等于粗磨砂轮的磨头厚度即可。优选地，第一轴向距离X为粗磨砂轮的磨头厚度加0.1-5mm(如1mm)。如通常情形下，第一轴向距离X取值范围为3-25mm。
主要参照图6，在一种可能的实施方式中，在精磨砂轮处于工作状态的情形下，粗磨砂轮的磨头缩回并与精磨砂轮外圆精磨面基准面之间形成第二轴向距离Y，与前述的X类似，如理论上Y等于精磨砂轮的磨头厚度即可。优选地，第二轴向距离Y为精磨砂轮的磨头厚度加0.1-5mm(如1mm)。如通常情形下，第二轴向距离Y的取值范围为3-25mm。
在一种具体的实施方式中，精磨砂轮的外径尺寸为335mm，精磨砂轮的内径尺寸为285mm。粗磨砂轮的外径尺寸为280mm，粗磨砂轮的内径尺寸为248mm。显然，精/粗磨砂轮的外/内径尺寸可以根据实际需求(如硅棒的宽度等)灵活地调整。不过，外圈的精磨砂轮的外径尺寸通常应当不小于100mm。粗磨砂轮的伸缩行程为18mm，第一轴向距离X为8mm，第二轴向距离Y等于精磨砂轮的磨头 厚度。主要参照图9，在一种可能的实施方式中，检测组件包括探针壳体321以及探针安装板322，探针安装板上设置有三个探针323，壳体内设置有滑台气缸324，滑台气缸与探针安装板驱动连接。在本示例中，气缸设置于壳体的底部外侧或者底部内侧。这样一来，在滑台气缸的作用下，探针安装板能够伸出壳体，安装于探针安装板上的三个探针此时便可靠近硅棒并因此检测硅棒的位置和姿态。
显然，滑台气缸只是实现探针伸缩的其中一种驱动方式，本领域技术人员可以根据实际需求灵活地选用合适的驱动机构，如可以用电缸、液压缸代替气缸，或者通过驱动电机和丝杠螺母副的组合来实现等。用于检测硅棒的部件除了采用与硅棒直接接触的探针外，还可以采用激光测距传感器、光栅尺等实现。
基于上述结构，本发明的磨床的工作过程大致为：
上料装置完成对硅棒的位姿调整后，进给滑台装置1根据对中组件测得的硅棒2的长度到达预定的位置后，动夹头相对于滑台组件沿进给方向运动，从而通过定夹头和动夹头之间的配合将硅棒夹紧。之后，进给滑台装置沿进给方向运动，将硅棒运送到磨削区域，进给滑台装置使硅棒按照程序的设定沿进给方向运动以及对硅棒进行旋转，并通过磨削装置完成相应的磨削作业。完成磨削后，进给滑台装置返回至上料装置的下料区，此时(定、动)夹头松开硅棒，使硅棒落至与下料区对应的下料平台，完成下料。
磨削作业前，磨削装置3中的检测组件32会对硅棒2的位置和姿态进行检测。具体地，当硅棒2来到第一个检测位置后停止运动，检测组件中的滑台气缸推动探针安装板向右运动，从而使得设置于探针安装板上的三个探针沿磨削进给方向运动，此时三个探针的探头位置会超前于磨削组件31中的粗磨砂轮和精磨砂轮。然后，磨削组件31和检测组件32在滑台驱动部件42的驱动下沿横梁滑台4继续运动，直到探针与硅棒接触并完成检测(打点未磨削)。伴随着硅棒沿进给方向的运动，探针如可以依次对硅棒的入刀口位置、沿棒长的中间位置以及硅棒的出刀口位置进行检测。
通过检测组件的检测结果，确定出是否对硅棒2进行磨削加工。具体而言，若硅棒的最大磨削尺寸小于磨削后的标准尺寸，则判定棒料尺寸不合格，无法磨削，如此时需要退棒，即将硅棒退回下料平台，之后进行不同程度的人工介入。在硅棒合格的前提下，则通过探针组对硅的三个位置的测量可以测得(定、动)夹头的轴线和硅棒的轴线之间的位置偏差和角度偏差，通过对偏差进行调整后重新检测，检测完毕后，可以开始磨削。检测过程中，可以计算出粗磨砂轮312的磨削量，根据磨削量，粗磨砂轮在第二驱动部件的驱动下伸出精磨砂轮311，以及在滑台驱动 部件42的驱动下前进一定距离，并通过第一驱动部件驱动复合轴转动从而带动粗磨砂轮转动并进行与磨削量对应的粗磨作业。粗磨结束后，可以通过第二驱动部件使粗磨砂轮缩回精磨砂轮中部形成的预留空间内。之后，检测组件重复之前的检测过程，计算出精磨砂轮311的磨削量，根据磨削量，精磨砂轮同样在滑台驱动部件42的驱动下前进一定距离，并通过第一驱动部件驱动复合轴转动从而带动精磨砂轮转动并进行与磨削量对应的精磨作业。
可以看出，在本发明的磨床中，通过将精磨砂轮和粗磨砂轮进行整合，使得基于磨床的同一个工位便可同时实现对硅棒的粗磨作业和精磨作业。通过复合轴的设置，保证了粗磨作业和精磨作业均能够无干涉地可靠实现。并且，由于粗磨砂轮和精磨砂轮产生相对滑动时，活动件为粗磨砂轮，因此能够保证精磨砂轮的精度完全不受影响。以及，通过将第一驱动部件设置于由安装基体和第一传动轴形成的安装空间内部，使得磨削组件更为紧凑。此外，在本发明中，第二驱动部件通过丝杠螺母副-连接座-轴承箱使得第二传动轴实现其相对于第一传动轴的伸缩运动，传动可靠且结构较为紧凑。
基于上述磨床的结构，下面来描述磨床的控制方法。
主要参照图10，图10示出本发明一种实施例的磨床的控制方法的流程示意图。如图10所示，在一种可能的实施方式中，本发明的控制方法主要包括如下步骤：
S1001、在对硅棒进行磨削作业之前，使滑台气缸运行，使单个探针伸出探针壳体接近硅棒，以及通过横梁沿固定基座的滑动使得探针到达硅棒的不同位置，以保证探针完成对硅棒的位置和姿态的检测。
在检测完毕后，使探针缩回至不干涉磨削作业的位置即可。可以理解的是，也可包含通过滑台沿横梁的滑动实现磨削组件与检测组件的同步接近/远离硅棒。
S1003、在硅棒的位置和姿态符合对其进行磨削作业的情形下，使第二驱动部件运行，通过丝杠螺母副的动力传动以及连接座在直线导轨中的滑动引导，使第二传动轴向右移动，从而使得粗磨砂轮向右伸出至对应于其处于工作状态的位置。
S905、使内置的第一驱动部件运行带动第二传动轴转动从而使得粗磨砂轮对硅棒进行相应的磨削量的粗磨作业。
可以理解的是，可以通过横梁沿固定基座的滑动使得粗磨砂轮到达硅棒的不同位置，从而保证粗磨砂轮能够对硅棒的不同位置进行相应的粗磨作业。
S1007、在对硅棒进行粗磨之后，再次使第二驱动部件运行通过过丝杠螺母副的动力传动以及连接座在直线导轨中的滑动引导，使第二传动轴向左移动，从而使得粗磨砂轮向左缩回至能够保证精磨砂轮处于工作状态的位置。
S1009、使内置的第一驱动部件运行带动第一传动轴转动从而使得精磨砂轮对硅棒进行相应的磨削量的精磨作业。
可以理解的是，与粗磨砂轮类似，可以通过横梁沿固定基座的滑动使得精磨砂轮到达硅棒的不同位置，从而保证精磨砂轮能够对硅棒的不同位置进行相应的粗磨作业。
在此基础上，通过使定/动夹头旋转电机运行从而使硅棒从一组磨削面转动至另一组磨削面。基于此，便可通过同一个工位集成的粗/精磨砂轮，完成对硅棒的磨削作业。
需要指出的是，尽管上述实施例中将各个步骤按照特定的先后顺序进行了描述，但是本领域技术人员可以理解，为了实现本发明的效果，不同的步骤之间并非必须按照这样的顺序执行，其可以同时执行或以其他顺序执行，也可以增加、替换或者省略某些步骤。
需要说明的是，尽管以上述具体方式所构成的磨床的控制方法作为示例进行了介绍，但本领域技术人员能够理解，本发明应不限于此。事实上，用户完全可根据以及实际应用场景等情形灵活地调整相关的步骤以及步骤中的参数等要素。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
