Description

一种用于超声波加工装置的压盖及超声波刀柄 技术领域
本发明涉及超声波加工技术领域，特别是涉及一种用于超声波加工装置、具有隔振功能的压盖及包括该压盖的超声波刀柄。
背景技术
在超声波加工技术中，换能器通过法兰与超声波刀柄本体固定连接，现有的固定连接方式往往有以下几种：
第一种为采用法兰通过螺钉和刀柄本体连接；
第二种为采用焊接将法兰固定于刀柄本体内；
这两种方式虽然能确保连接刚度；然而，由于法兰存在不可避免的振动，法兰的振动将会造成超声波振动能量消耗，使得传递到加工工具上的有效能量变少，进而导致加工效率较低；特别是法兰的振动还会引起刀柄本体振动，该振动向连接于其后端的机床主轴传递，不仅会影响机床主轴的转动，且会对机床主轴产生冲击甚至造成机床损坏，进而会影响到机床主轴的精度。
第三种为通过压盖1等紧固件的方式将法兰锁紧固定于刀柄本体2内(参见附图1)，这种方式仍不能完全有效的防止换能器3不转动，从而丧失加工精度；并且在该方式中，压盖1装配至刀柄本体2后，为了确保压盖1不会影响超声波刀柄的圆跳动和动平衡，需要通过车床在压盖1的退刀槽处对压盖进行裁剪。
其次，在现有技术中超声波加工装置往往需要进行动平衡调整，而上述固定连接的方式均不能提供动平衡调整，需要设置专门的动平衡装置，如设置动平衡环来调整动平衡，以满足高速加工的需求，这样降低了整个超声波加工装置的刚度和整体性。
发明内容
本发明目的是提供一种用于超声波加工装置、具有隔振功能的压盖及包括该压盖的超声波刀柄，能够有避免超声波振动影响机床主轴转动及损坏机床主轴；
且进一步地，本发明的另一个目的是不需要另设专门的动平衡装置如动平衡环，也可以调整超声波刀柄的动平衡。
为了实现上述目的，本发明的一方面提供了一种用于超声波加工装置的压盖，其包括中空的压盖本体，所述压盖本体的后端用于与超声波加工装置本体连接，所述压盖本体的前端的外缘设有环形凸起部，所述环形凸起部上设置有多个减振孔。
作为优选方案，所述压盖本体和所述环形凸起部为一体成型。
作为优选方案，所述减振孔沿所述环形凸起部的轴向和/或径向开设于所述环形凸起部上。

作为优选方案，所述减振孔与所述减振槽相连通。
作为优选方案，所述减振槽开设于所述环形凸起部的轴向厚度的中心位置，且所述减振孔的深度大于所述环形凸起部轴向厚度的一半。
作为优选方案，还包括配重部件，所述环形凸起部和压盖本体的连接处设有退刀槽，径向开设于所述环形凸起部的减振孔的底部较所述退刀槽的底部更靠近于所述环形凸起部的中心。
作为优选方案，所述环形凸起部和压盖本体的连接处设有退刀槽，所述退刀槽的底部较所述环形槽的底部更靠近于所述环形凸起部的中心。
作为优选方案，轴向开设于所述环形凸起部的减振孔的开口方向朝向所述环形凸起部的前端。
作为优选方案，所述压盖还包括配重部件，至少一部分所述减振孔与所述配重部件配合，以用于调整所述超声波加工装置的动平衡。
作为优选方案，所述减振孔为螺纹孔，所述配重部件为与所述螺纹孔螺纹配 合连接的螺钉。
作为优选方案，所述减振孔为圆形孔或非圆形孔。
为了实现相同的目的，本发明还提供一种超声波刀柄，包括：
上述的压盖；
刀柄本体，所述刀柄本体设有前端开口的内腔，所述压盖插设于所述刀柄本体的前端，所述刀柄本体的后端用于与机床主轴连接；
换能器，所述换能器的外缘设置有法兰；
所述换能器从所述刀柄本体的前端插入所述压盖和所述刀柄本体的内腔，并通过所述压盖压紧连接于所述刀柄本体的前端；
所述压盖本体的后端被压紧于所述刀柄本体的内侧壁、换能器的外侧壁和法兰的前端面之间，所述环形凸起部抵接在所述刀柄本体的前端面。
与现有技术相比，本发明的有益效果：
本发明所提供的压盖，在完成与超声波加工装置的装配后，无需对压盖的环形凸起部进行裁剪，减少了加工工序，且能够有效地减少超声波振动传递到超声波加工装置本体的后端，进而避免超声波振动影响机床主轴转动及损坏机床主轴；进一步，由于环形凸起部上设置有减振孔，该减振孔可以有效地减少由换能器传递过来的超声波振动。
进一步地，减振孔可以用于装配配重部件，在需要调整超声波加工装置的动平衡时如更换不同加工工具，在减振孔内装配上不同重量的配重部件，可以调整整个超声波加工装置的动平衡，从而提高了加工精度，同时避免了需要安装专门的动平衡装置来调整动平衡，有效的保证超声波加工装置的刚度和整体性。
当该压盖应用于超声波刀柄上时，从而减少由换能器的法兰传递到压盖的超声波振动能量传递到刀柄上，进而能够避免超声波振动影响机床主轴转动及损坏机床主轴。

具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，其中紧固件采用压盖这一具体形式，超声波加工装置本体采用刀柄本体这一具体形式，但不用来限制本发明的范围。
在本发明的描述中，需要理解的是，术语“上”、“下”、“左”、“右”、“顶”、“底”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。应当理解的是，本发明中采用术语“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，在不脱离本发明范围的情况下，“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。
另外需要说明的是，本发明的描述中，术语“前端”和“后端”指的是，在超声 波加工装置安装有加工工具时，靠近于加工工具的一端为“前端”，背离加工工具的一端为“后端”。
本发明的第一方面提出一种用于超声波加工装置、具有隔振功能的压盖，压盖的具体实施方式如下：
实施例一
具体参阅附图2A、2B、2C，本实施例提供了一种用于超声波加工装置的压盖1，该压盖1包括有为压盖本体11和环形凸起部12，压盖本体11的后端为用于与超声波加工装置本体连接的压紧部，压盖本体11的前端的外缘设有环形凸起部12，该环形凸起部12上设置有多个减振孔13。
在本实施例中，优选地，如图2A所示，多个减振孔13径向均匀设置于环形凸起部12的外缘，即减振孔13沿压盖本体11的径向开设于环形凸起部12的外缘上。减振孔13是但不限于各类具体形状的孔，如可为圆形孔或非圆形孔，如三角形孔、五角孔、锥形孔等。
作为可替换方案，可将减振孔13沿压盖本体的轴向设置，即在环形凸起部12的端面开设有减振孔13；同样地，可同时在环形凸起部12的端面及外缘开设所述减振孔13。
优选地，压盖本体11和环形凸起部12为一体成型，一体成型的压盖本体11和环形凸起部12与二者分开成型后再固定安装在一起的方式相比，提高了压盖1的整体刚度，节省了加工工序，且压盖本体11和环形凸起部12不可拆分，使得压盖1的使用安全性能更高。
本实施例的压盖还包括配重部件(图中未示出)，至少一部分减振孔13与配重部件配合，用于调整所述超声波加工装置的动平衡，在更换不同的加工工具的时候，通过在压盖1的减振孔13上装配不同重量的配重部件，可调整整个超声波加工装置的动平衡，从而提高了加工精度，特别是避免了采用专门的动平衡装置来调整超声波加工装置的动平衡，有效的保证超声波加工装置的刚度和整体 性。具体而言，减振孔13为螺纹孔，配重部件为螺钉，减振孔13与配重部件通过螺纹配合连接。需要指出的是，减振孔13和配重部件也可通过其他常用的连接方式进行连接。
更进一步地，压盖本体11的外周面上设置有外螺纹，以用于与超声波加工装置本体螺纹连接。
本实施例中，如图2C所示，为了简化加工工序，所述环形凸起部12和压盖本体11的连接处设有退刀槽15，所述减振孔13的底部较所述退刀槽15的底部更靠近于所述环形凸起部12的中心，由此对环形凸起部12进一步进行减材处理，可进一步有效减少超声波振动。
实施例二
具体参阅附图3A、3B、3C，本实施例提供了一种用于超声波加工装置的压盖1，其与实施例一的区别仅在于：多个减振孔13沿环形凸起部12的轴向均匀设置于环形凸起部12上，且该减振孔13的开口方向朝向环形凸起部12的前端。优选地，为了进一步提高减振效果，减振孔13的深度大于环形凸起部12的轴向厚度的一半。此外，如图3C所示，本实施例的减振孔13的靠近环形凸起部12的中心的侧壁与退刀槽15的底部齐平。
本实施例的压盖1的其它结构与实施例一相同，在此不再进行赘述。
实施例三
具体参阅附图4A、4B、4C，本实施例提供的一种超声波加工装置中的压盖1，其与实施例二的区别仅在于，在环形凸起部12的外缘周向上还开设了减振槽14，该减振槽14为环绕环形凸起部12且设于环形凸起部12轴向厚度的中心位置的环形槽，且轴向设置的减振孔13与减振槽14相通，设置减振槽14与减振孔13相配合，可以将超声波振动向四周传递扩散，由此可有效降低甚至隔离超声波振动。
另外，如图4C所示，减振孔13的底部较退刀槽15的底部更靠近于环形凸 起部12的中心，由此可在确保减振效果的同时，提高压盖1的整体刚度。
本实施例的压盖1的其它结构与实施例二相同，在此不再进行赘述。
上述所有实施例中的压盖1均可用于超声波加工装置中，超声波加工装置包括超声波刀柄、超声波夹具、超声波主轴及超声波机床等；本发明以超声波刀柄为例。
本发明的第二方面提供了一种超声波刀柄，其包括：上述任一实施例所提供的压盖1、刀柄本体2和换能器3。
其中，刀柄本体2设有前端开口的内腔，压盖1插设于刀柄本体2的前端，刀柄本体2的后端用于与机床主轴连接；换能器3的外缘设置有法兰31，且换能器3的前端用于安装加工工具；换能器3从刀柄本体2的前端插入压盖1和刀柄本体2的内腔，并通过压盖1压紧连接于刀柄本体2的前端；压盖本体11的后端为压紧部，其被压紧于刀柄本体2的内侧壁、换能器3的外侧壁和法兰31的前端面之间，而环形凸起部12则抵接在刀柄本体2的前端面。本实施例中，加工工具包括刀具、磨头及砂轮盘等。
一方面，压盖1能给换能器3的法兰31提供压紧力，使法兰31与超声波刀柄本体2组合更加紧密，加强了产品的结构强度。另一方面，由于减振孔13和减振槽14均设于环形凸起部12上，而环形凸起部12则抵接在刀柄本体2的前端面，并没有被压紧在刀柄本体2的内侧壁和换能器3的外侧壁之间，由此超声波振动可以经法兰31直接传递到压盖1上，而压盖1上具有的减振孔13和减振槽14则可以将超声波振动消耗掉，从而避免由法兰31产生的这部分超声波振动传递到刀柄上。
进一步，刀柄本体2的内腔的内侧壁上设置有台阶21，法兰31的后端面抵接于所述台阶21。
所述压盖1套设于所述换能器3的外周，压盖本体11的另一端的端面抵接于所述法兰31的前端面，以便对法兰31进行压紧。
本发明的压盖1在装配至刀柄本体2之后，无需对其中的环形凸起部12进 行裁剪，进一步减少了加工工序；进一步，由于环形凸起部12上设置有减振孔13和/或减振槽14，这些减振孔13和/或减振槽14可以有效地消耗部分超声波振动，从而避免由法兰31产生的这部分超声波振动能量传递到刀柄上；
且这些减振孔13还可以用于装配配重部件，在需要调整超声波加工装置的动平衡时如更换不同加工工具，在孔内装配上不同重量的配重部件，可以调整整个超声波加工装置的动平衡，从而提高了加工精度，同时避免了需要安装专门的动平衡装置来调整动平衡，有效的保证超声波加工装置的刚度和整体性。

表1为各个实施例中的实验对比表
如表1所示，以超声波刀柄为例，压盖1锁紧于刀柄本体2后，现有技术的压盖为在退刀槽处对压盖进行裁剪后的普通压盖结构(具体参见附图1)，本发明的压盖1为实施例一、二和三的压盖结构。经过实验表明，本发明的压盖在降低刀柄本体后端的振动的同时可以有效地提高刀柄前段的振幅。从实验数据可进一步得出，在环形凸起部12上设置减振孔13可进一步降低刀柄本体后端的振动，尤其是在环形凸起部12同时设置减振槽14和减振孔13后对刀柄本体后端的减振效果更佳。
综上，本发明所提供的压盖，在完成与超声波加工装置的装配后，无需对压盖的环形凸起部进行裁剪，减少了加工工序；进一步，由于环形凸起部上设置有减振孔，该减振孔可以有效地减少由换能器传递过来的超声波振动，能够有效地减少超声波振动传递到超声波加工装置本体的后端，进而避免超声波振动影响机床主轴转动及损坏机床主轴。
进一步地，减振孔可以用于装配配重部件，在需要调整超声波加工装置的动平衡时如更换不同加工工具，在减振孔内装配上不同重量的配重部件，可以调整整个超声波加工装置的动平衡，从而提高了加工精度，同时避免了需要安装专门 的动平衡装置来调整动平衡，有效的保证超声波加工装置的刚度和整体性。
当该压盖应用于超声波刀柄上时，从而减少由换能器的法兰传递到压盖的超声波振动能量传递到刀柄上，进而能够避免超声波振动影响机床主轴转动及损坏机床主轴。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和替换，这些改进和替换也应视为本发明的保护范围。
