首先，需要说明的是，在本文中所提到的顶部、底部、朝上、朝下等方位是相对于各个附图中的方向来定义的，它们是相对的概念，并且因此能够根据其所处于的不同位置和不同的实用状态而改变。所以，不应将这些或其他方位用于理解为限制性用语。
应注意，术语“包括”并不排除其他要素或步骤，并且“一”或“一个”并不排除复数。
此外，还应当指出的是，对于本文的实施例中描述或隐含的任意单个技术特征，或在附图中示出或隐含的任意单个技术特征，仍能够在这些技术特征(或其等同物)之间继续进行组合，从而获得未在本文中直接提及 的本申请的其他实施例。
另外还应当理解的是，本文中采用术语“第一”、“第二”等来描述各种信息，但这些信息不应限于这些术语，这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本申请范围的情况下，“第一”信息也可以被称为“第二”信息，类似的，“第二”信息也可以被称为“第一”信息。
应当注意的是，在不同的附图中，相同的参考标号表示相同或大致相同的组件。
另外，需要说明的是，本申请中的“前端”、“后端”、“内侧”、“外侧”分别指的是：利用该超声波加工设备加工工件时，靠近加工表面的一端为前端，背离加工表面的一端为后端，靠近超声波刀柄的中心轴线的一侧为内侧，背离超声波刀柄的中心轴线的一侧为外侧。“轴向”、“径向”在未具体说明的情况下分别指的是：沿旋转轴的旋转轴向的方向为轴向，而垂直并指向旋转轴的旋转轴向为径向。
如图1-15所示，本申请提供一种超声波设备，包括超声波主轴和超声波刀柄200。
参考图1-图2，超声波主轴包括主轴壳体110、旋转轴组件120和超声波无线发射装置1410，其中，超声波无线发射装置1410包括发射架130和超声波无线发射单元140。
具体的，参考1和图4，旋转轴组件120可转动的穿设于主轴壳体110内，旋转轴组件120的前端面开设有安装孔；发射架130设置于主轴壳体110的前侧，该“前侧”指的是位于主轴壳体1的前方位置；发射架130包括发射部131，发射部131呈绕于旋转轴组件120的中心轴线设置的非整圆环状，发射部131的内侧面开设有呈绕于旋转轴组件120的中心轴线设置的非整圆环状的第一容纳槽132；超声波无线发射单元140设于第一容纳槽132内，参考图5，超声波无线发射单元140包括发射线圈141和用于容置发射线圈141的发射铁氧体142；
其中，参考图11，发射部131的圆心角为α弧度，需要指出的是，本实施例中发射部131的圆心角具体指的是发射部131绕其圆心在周向上所延伸的角度，也即发射部131的两端周向最外侧的位置与其圆心连接后形成的夹角，
Figure PCTCN2021129399-appb-000004
针对不同型号的刀柄结构通常可取用不同数值的圆心角，以满足换刀要求，并保证无线传输要求。
示例性地，该发射部131整体可以为三分之一、四分之一圆环状；同时，第一容纳槽132的圆心角与发射部131的圆心角相同或基本相同。
参考图1和图3，超声波刀柄200包括刀柄本体210和超声波无线接收单元220，刀柄本体210的外周设有沿轴向依次设置的卡刀位211及第二容纳槽240，第二容纳槽240呈圆环状且环绕刀柄本体210；超声波无线接收单元220设于第二容纳槽240内，用于配合超声波无线发射单元140实现超声波无线电能传输。

基于上述方案，实现超声波无线发射单元140与超声波无线接收单元220进行无线电能传输的同时，通过设置发射架130，发射架130包括发射部131，发射部131的圆心角
Figure PCTCN2021129399-appb-000005
并在开设于发射部131呈非整圆环状的第一容纳槽132内设置超声波无线发射单元140，从而将超声波刀柄200配合安装于超声波主轴上后，发射架130能够为刀库自动换刀让出空间，从而使得不同超声波刀柄200之间、以及超声波刀柄200与普通刀柄之间可通用刀库，实现设备刀库的通用性，从而能够大幅度减少设计及制造成本。
进一步优选的，
Figure PCTCN2021129399-appb-000006
进一步的，参考图2、图6、图10-图13，在本实施例中，超声波无线发射单元140包括发射线圈141和用于容置发射线圈141的发射铁氧体142，发射铁氧体142的内侧面开设有第一埋线槽142a，第一埋线槽142a内设有呈弧形的间隔板142b，第一埋线槽142a的前后两侧的至少一侧设有弧形侧壁143c，间隔板142b与弧形侧壁143c同轴设置，发射线圈141绕设于间隔板142b并容纳于第一埋线槽142a内，从而使设置于弧形侧壁143c与间隔板142b之间的发射线圈141形成发射边。
可选的，参考图3、图14和图15，本实施例中，刀柄本体210上套设有设于超声波无线接收单元220前端的支撑环形板230，刀柄本体210的外侧面具有设于超声波无线接收单元220后端的凸环部213，支撑环形板230与凸环部213之间形成第二容纳槽240，如此，可通过拆卸支撑环形板230后，将超声波无线接收单元220从刀柄本体210的前端卸下，便于超声波无线接收单元220的可靠安装及拆卸方便；具体的，本实施例中的卡刀位211设于凸环部213后端。
参考图5和图6，其中，超声波无线接收单元220包括环绕刀柄本体210设置的接收线圈221和用于容置接收线圈221的接收铁氧体222，接收铁氧体222的外侧面开设有环绕刀柄本体210的第二埋线槽221a， 第二埋线槽221a内容纳有接收线圈221，如此，实现第二埋线槽221a内的接收线圈221与第一埋线槽142a内设置于间隔板142b和弧形侧壁143c之间的发射线圈141相对设置。
进一步优选的，参考图9和图10，本实施例中的发射部131的内侧面开设有呈弧形的灌胶槽133，灌胶槽133位于第一容纳槽132的前侧，发射架130开设有与第一容纳槽132连通的第一灌胶通道134，第一容纳槽132与灌胶槽133之间开设有连通第一容纳槽132与灌胶槽133的第二灌胶通道135，从而便于将胶体从第一灌胶通道135中注入后，对第一容纳槽132和灌胶槽133填充胶体，提高发射铁氧体142设置于第一容纳槽132内的稳定性。
具体的，参考图1，本实施例中，超声波主轴100还包括安装臂150，安装臂150的一端与发射架130连接，另一端连接至主轴壳体110的外侧，从而实现超声波无线发射单元140的悬挂式安装，无需改变主轴结构，降低改装的成本，同时，超声波主轴100适用普通刀柄进行安装加工，使用范围更广，降低使用的成本。
优选的，参考图4和图5，旋转轴组件120的外侧与主轴壳体110的内侧之间设有轴承160，旋转轴组件120的前端安装有前端盖170，前端盖170从前往后压紧于轴承160的外圈，旋转轴组件120的前端外周设有压环180，压环180从前往后压紧于轴承160的内圈。通过分别设置压盖及压环180以抵压轴承160，能够便于将主轴壳体110稳定装配至旋转轴组件120外部。
需要说明的是，参考图16和图17，在另一实施例中，发射架130也可连接于前端盖170上，具体的，发射架130连接于前端盖170的前端面，进一步优选的，发射架130与前端盖170一体成型，即发射架130集成于超声波主轴100的前端盖170上。
进一步的，参考图5和图8，在本实施例中，为了能够适用于重载荷及重切削力的主轴及工况，旋转轴组件120的前端外周还套设有定位环190，定位环190的前端设有定位部191；相对应地，刀柄本体210的外周设有延伸至其后端面的定位槽212，且通常定位槽212的后端延伸至与卡刀位211相连通；在装配超声波刀柄200时，利用定位部191与定位槽212之间的配合定位能够实现超声波刀柄200的周向定位，避免重载荷及重切削力作用下，超声波刀柄200与旋转轴组件120相对转动。
进一步地。参考图5和图7，为了实现转动组件与固定组件之间良好的正压密封，前端盖170的内周面与压环180的外周面之间留有第一间隙181，且前端盖170的内周面沿轴向间隔设有若干环形凸筋173；且前端盖170的前端沿其内周面开设有环形的台阶面171，定位环190的后端沿其外周面设有与前端盖170的台阶面171配合的台阶结构192，台阶面171与台阶结构192之间形成有迷宫气道172，能够防止灰尘、水等从前往后侵入；通常主轴壳体110上设有气道，气道从主轴壳体110与旋转轴组件120之间的空隙中从后往前吹，并经过第一间隙181后最终经迷宫气道172朝前吹出。
进一步优选的，参考图5和图6，本申请中，超声波无线接收单元220的外侧面与超声波无线发射单元140的内侧面之间设有第二间隙300；且第二间隙300的宽度L优选为0.1毫米～2.5毫米，在保证获得较大的传输效率的同时，能够避免装配或者使用过程中相互之间的干涉、磕碰。
进一步的，参考图9和图13，本发明的一个实施例中，第一容纳槽132的容积为V立方毫米，发射线圈141的体积为V 1立方毫米，发射铁氧体142的体积为V 2立方毫米，且V 2＝V 1K 1，发射线圈141的匝数为N，组成发射线圈141的单匝导线的横截面积为S平方毫米，发射部131的内侧面的直径为D 1毫米，第一容纳槽132的槽底面的直径为D 2毫米，发射部131的圆心角为α，则上述参数值满足如下函数关系：
V＝(V 1+V 2)K 2＝[V 1(1+K 1)]K 2＝[αNSD 1(1+K 1)]K 2
1≤K 1≤8
1<K 2≤3
其中，10≤N≤300，0.02≤S≤2.6。
在此基础上，若第一容纳槽132的容积值V与发射架130的内侧面的直径值D 1还满足如下函数关系：
Figure PCTCN2021129399-appb-000007
0.5≤K 3≤2.5
当满足上述函数关系时，首先能够实现对容置超声波无线发射单元140的第一容纳槽132的容积与发射部131的内侧直径以及圆心角相适配，而发射部131的内侧面直径尺寸随超声波刀柄200的型号发生适应性变化，也即本申请能够根据不同型号的刀柄对超声波无线发射单元140的发射部131的圆心角及第一容纳槽132的容积进行优化设计；另外，本申请还将超声波无线发射单元140中的发射线圈141的匝数、单匝导线的横截面积、发射铁氧体142的体积之间实现优化配置，在确定发射部131的圆心角以及第一容纳槽132的容积后对发射铁氧体142及发射线圈141进行优化配置，从而保证电信号传输的稳定可靠性，并优化加工性能，以满足加工需求。
其中，参考图11，图11中的阴影部分面积延伸至发射部131后端面所形成的体积为第一容纳槽132的容积。
进一步优选的，80≤N≤160，
Figure PCTCN2021129399-appb-000008
其中，上述函数关系中，K 1、K 2、K 3为修正系数。在超声波主轴与超声波刀柄200的装配关系中，发射架130的内侧面的直径与超声波刀柄200的规格相关，也就是与超声波主轴的规格相关，不同规格的超声波刀柄200和超声波主轴，其所对应的发射架130的内侧面的直径不同。发射线圈141的匝数是指导线环绕第一埋线槽142a内周的圈数，并且，该导线即可以是单芯线，也可以是多芯线，比如，一匝导线由五根线芯组成。导线的横截面可以是圆形、三角形、矩形等，也可以是其他不规则形状，但无论导线的横截面为何种形状，都可以按照与其等效的圆形来计算横截面积，即，导线的线径为D 3毫米，则有S＝π(D 3/2) 2。
以下具体示出了几种不同超声波设备的具体实施例，且各实施例中的发射部131及超声波无线发射单元140的结构参数值满足上述函数关系：
实施例一
本实施例中的超声波设备，其超声波刀柄200的型号为BT30，与之相对应地，发射部131及超声波无线发射单元140的具体结构参数值为：
α＝1.868，V＝7176.14，D 1＝46.5，D 2＝67，D 3＝0.35，N＝144。
实施例二
本实施例中的超声波设备，其超声波刀柄200的型号为BT40，与之相对应地，发射部131及超声波无线发射单元140的具体结构参数值为：

实施例三
本实施例中的超声波设备，其超声波刀柄200的型号为BT50，与之相对应地，发射部131及超声波无线发射单元140的具体结构参数值为：
α＝1.632，V＝19223.93，D 1＝101，D 2＝125，D 3＝0.5，N＝130。
实施例四
本实施例中的超声波设备，其超声波刀柄200的型号为HSK-A63，与之相对应地，发射部131及超声波无线发射单元140的具体结构参数值为：
α＝1.947，V＝13108.62，D 1＝65，D 2＝90，D 3＝0.5，N＝150。
实施例五
本实施例中的超声波设备，其超声波刀柄200的型号为HSK-A100，与之相对应地，发射部131及超声波无线发射单元140的具体结构参数值为：
α＝1.745，V＝39581.16，D 1＝101.2，D 2＝135，D 3＝0.5，N＝160。
为了验证本申请中上述参数值满足上述函数关系式时各超声波设备的加工性能，技术人员对上述实施例中各超声波设备所能达到的最大振幅进行了测试，并分别与现有技术中的超声波设备所能达到的最大振幅一一进行了比对，本申请的超声波设备与现有技术的超声波设备的区别在于，现有技术的超声波设备的超声波无线发射单元140为全环式结构，具体参阅表1、表2、表3、表4及表5所示。

表4

表5
由表1～表5可知，在相同的测试条件下，本发明的实施例提供的超声波设备相比现有技术中采用全环式结构的超声波无线发射单元140的超声波设备，在本申请的发射部131的圆心角均小于2π/3时，超声波无线发射单元140的周向发射范围减小了2/3以上，即超声波无线发射单元140的周向发射范围为全环式超声波无线发射单元的1/3，此时，本申请中各实施例中的超声波加工设备所能达到的最大振幅相较于全环式结构的超声波加工设备来说，减小的幅度很小，能够至少维持至全环发射时性能的80％左右，可满足用户加工绝大部分工件时对于超声波加工设备的性能需求，并保证电导通的稳定性。
需要指出的是，在本实用新型中，表1-表5中的振幅值为峰-峰值，即一个周期内振幅的正峰值与负峰值之间的差值。
可选的，参考图5、图6、图13和图15，本实施例中的第一埋线槽142a的前后两侧均设有弧形侧壁143c，超声波无线接收单元220包括环绕刀柄本体210设置的接收线圈221和用于容置接收线圈221的接收铁氧体 222，接收铁氧体222的外侧面开设有两条沿刀柄本体210轴向依次设置并环绕刀柄本体210的第二埋线槽221a，第二埋线槽221a内容纳有接收线圈221；其中，两条第二埋线槽221a内容纳的接收线圈221分别一一对应间隔板142b与间隔板142b两侧的发射边，从而使发射线圈141产生的磁场能量尽可能被利用，进而产生较大的励磁电感量，提高传输效率。
其中，本实施例中的弧形侧壁143c的弧长大于间隔板142b的弧长，增大发射线圈141在绕间隔板142b时可布置形成的有效面积，从而进一步增大励磁电感量，提高传输效率；具体的，弧形侧壁143c和间隔板142b的轴向厚度C均为0.5毫米～10毫米，以保证超声波无线发射单元140能够产生足够的励磁电感量，提高无线传输效率。
综上，本发明实施例中的超声波主轴，一方面，通过将传统的全环式无线发射装置替换成非全环式，在将超声波刀柄200配合安装于超声波主轴上后，超声波无线发射单元140能够在刀柄本体210的卡刀位211处留出换刀空间，从而能够供刀库进行自动换刀，实现刀库的通用性，使得成本大幅度降低；
另一方面，本申请通过优化设计发射架130及超声波无线发射单元140，使其满足以下函数关系：
Figure PCTCN2021129399-appb-000015
其中，10≤N≤300，0.02≤S≤2.6，1≤K 1≤8，1<K 2≤3，0.5≤K 3≤2.5，K 1、K 2、K 3为修正系数；
从而能够实现超声波无线发射单元140的总体积与发射部131的内侧面直径相适配，而发射部131的内侧面直径尺寸随超声波刀柄200的型号发生适应性变化，从而根据不同型号的刀柄对超声波无线发射单元140进行优化适配。
