因此，本发明实施例基于上述问题，提出一种仿形底座，包括：与打磨工件相匹配的底座、至少一个塞头和伸缩组件；伸缩组件可以控制塞头伸缩，从而在对打磨工件进行打磨时塞头伸入孔位，对孔位起到支撑作用。
下面以具体地实施例对本发明的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图3为本发明提供的仿形底座一实施例的俯视结构图。如图3所示，本实施例的仿形底座可以包括：
与打磨工件相匹配的底座3、至少一个塞头4和伸缩组件5；
其中，所述伸缩组件5固定设置在所述底座3上，且与所述塞头4连接；所述伸缩组件5用于控制所述塞头4伸缩。
具体的，仿形底座，包括与打磨工件的形状相匹配的底座3，固定在底座3上的伸缩组件5，以及与伸缩组件5相连的至少一个塞头4。
其中，塞头的数量与打磨工件的孔位的数量相同，而且塞头在底座上的位置与孔位在打磨工件上所处的位置对应。图3中仅以两个塞头为例进行说明。
塞头用于在对打磨工件进行打磨时，伸入打磨工件的孔位中，对孔位起到支撑作用，防止打磨头对打磨工件进行打磨时将孔位边缘打塌陷，而且也能够将孔位边缘的分型线打磨干净。
在对打磨工件进行打磨之前，伸缩组件可以控制塞头收缩在底座上，从而可以将打磨工件固定在底座上；在对打磨工件进行打磨时，伸缩组件可以控制塞头伸入打磨 工件的孔位中。
示例性的，若对手机外壳的分型线进行打磨时，手机外壳具有耳机孔和USB孔，则相应的塞头可以设置两个，而且位置与耳机孔和USB孔在手机外壳的位置相对应，则在打磨前，通过伸缩组件控制两个塞头将塞头收缩在底座上，在打磨时，通过伸缩组件控制塞头伸入手机外壳的耳机孔和USB孔中，则在打磨过程中，不容易将耳机孔和USB孔的孔位边缘打塌陷，而且也能够将耳机孔和USB孔的孔位边缘的分型线打磨干净。
本实施例提供的仿形底座，包括：与打磨工件相匹配的底座、至少一个塞头和伸缩组件；其中，所述伸缩组件固定设置在所述底座上，且与所述塞头连接；所述伸缩组件用于控制所述塞头伸缩，对打磨工件进行打磨时，伸缩组件可以控制塞头伸入打磨工件的孔位中，对孔位起到支撑作用，因此不容易将打磨工件的孔位边缘打塌陷，而且也能够将打磨工件的孔位边缘的分型线打磨干净。
图4为本发明提供的仿形底座另一实施例的俯视结构图。在上述实施例的基础上，如图4所示，本实施例中，若所述塞头的数量为一个时，则所述伸缩组件包括：第一导轨51、中心轴52、转盘53、操作手柄54；
其中，所述中心轴52固定设置在所述底座3上；所述转盘53套设在所述中心轴52上；

所述转盘53包括贯通所述转盘的第一滑槽531，所述第一滑槽531呈弧形状；所第一滑槽531的一端与所述中心轴52之间的距离，大于，所述第一滑槽531的另一端与所述中心轴52之间的距离；
所述第一导轨51的一端上设有第一连接件511，所述第一连接件511穿设在所述第一滑槽531内；
所述第一导轨51的另一端与所述塞头41固定连接；
所述底座3上设有第一滑道；所述第一导轨51设置在所述第一滑道上。
具体的，本实施例中，若打磨工件只具有一个孔位，相应的，仿形底座也可以设置一个塞头，即塞头41，相应的，伸缩组件包括：第一导轨51、中心轴52、转盘53、操作手柄54；其中，所述中心轴52固定设置在所述底座3上，所述转盘53套设在所述中心轴52上，所述操作手柄54固定在所述转盘53上，操作手柄54可以控制转盘 54绕着中心轴52转动。
如图4所示，转盘53包括贯通转盘的第一滑槽531，第一滑槽531呈弧形状；第一滑槽531的一端与中心轴52之间的距离，大于，第一滑槽531的另一端与中心轴52之间的距离。第一导轨51的一端上设有第一连接件511，第一连接件511穿设在第一滑槽531内，第一导轨51的另一端与所述塞头41固定连接，第一导轨51铺设在底座3的第一滑道上，在转盘53转动的过程中第一滑槽531带动第一连接件511移动，从而带动第一导轨51和塞头41伸出于底座3或收缩在底座3上。
具体的，在转盘转动的过程中，由于第一滑槽的一端与所述中心轴之间的距离，大于，所述第一滑槽的另一端与所述中心轴之间的距离，因此第一滑槽能够带动第一连接件移动，从而带动第一导轨和塞头伸出于底座或收缩在底座上。
其中，在实际应用中，第一连接件可以为销钉。
图5为本发明提供的仿形底座一实施例的应用场景示意图。如图5所示，在对打磨工件2打磨时，将仿形底座固定在机台上，将打磨工件2放到仿形底座上，通过扳动控制操作手柄54，带动转盘转动，从而使得塞头伸入打磨工件2的孔位21中。
上述具体实施方式中，通过转盘的转动，带动第一导轨和塞头伸缩，从而能够在对打磨工件进行打磨时，可以控制塞头伸入打磨工件的孔位中，对孔位起到支撑作用，因此不容易将打磨工件的孔位边缘打塌陷，而且也能够将打磨工件的孔位边缘的分型线打磨干净。
图6为本发明提供的仿形底座另一实施例的俯视结构图。图7为本发明提供的仿形底座又一实施例的俯视结构图。在上述实施例的基础上，如图6、图7所示，本实施例中，若所述塞头的数量为两个时，则所述伸缩组件包括：第一导轨51、中心轴52、转盘53、操作手柄54；
其中，所述中心轴52固定设置在所述底座3上；所述转盘53套设在所述中心轴52上；
所述操作手柄54固定在所述转盘53上；
所述转盘53包括贯通所述转盘的第一滑槽531，所述第一滑槽531呈弧形状；所第一滑槽531的一端与所述中心轴52之间的距离，大于，所述第一滑槽531的另一端与所述中心轴52之间的距离；
所述第一导轨51的一端上设有第一连接件511，所述第一连接件511穿设在所述 第一滑槽531内；
所述第一导轨51的另一端与其中一个塞头41固定连接；
所述底座3上设有第一滑道；所述第一导轨51设置在所述第一滑道上。
伸缩组件还包括：第二导轨55；
其中，所述转盘53还包括贯通所述转盘53的第二滑槽532，所述第二滑槽532呈弧形状；第二滑槽532的一端与所述中心轴52之间的距离，大于，所述第二滑槽532的另一端与所述中心轴52之间的距离；
所述第二导轨55的一端上设有第二连接件551，所述第二连接件551穿设在所述第二滑槽532内；
所述第二导轨55的另一端与另一个塞头42固定连接；
所述底座3上还设有第二滑道；所述第二导轨55设置在所述第二滑道上。
具体的，本实施例中，若打磨工件具有二个孔位，相应的，仿形底座也可以设置二个塞头，即包括塞头41和塞头42，相应的，伸缩组件包括：第一导轨51、中心轴52、转盘53、操作手柄54和第二导轨55；其中，所述中心轴52固定设置在所述底座3上，所述转盘53套设在所述中心轴52上，所述操作手柄54固定在所述转盘53上，操作手柄54可以控制转盘53绕着中心轴52转动。
如图6、图7所示，转盘53包括贯通转盘的第一滑槽531和第二滑槽532，第一滑槽531和第二滑槽532呈弧形状；第一滑槽531的一端与中心轴52之间的距离，大于，第一滑槽531的另一端与中心轴52之间的距离；第二滑槽532的一端与中心轴52之间的距离，大于，第二滑槽532的另一端与中心轴52之间的距离。第一导轨51的一端上设有第一连接件511，第一连接件511穿设在第一滑槽531内，第一导轨51的另一端与其中一个塞头41固定连接，第一导轨51铺设在底座3的第一滑道上，在转盘53转动的过程中第一滑槽531带动第一连接件511移动，从而带动第一导轨51和塞头41伸出于底座或收缩在底座上(如图6、图7所示，第一连接件远离中心轴或者朝向中心轴移动)。第二导轨55的一端上设有第二连接件551，第二连接件551穿设在第二滑槽532内，第二导轨55的另一端与另一个塞头42固定连接，第二导轨55铺设在底座3的第二滑道上，在转盘53转动的过程中第二滑槽532带动第二连接件551移动，从而带动第二导轨55和塞头42伸出于底座或收缩在底座上(如图6、图7所示，第二连接件远离中心轴或者朝向中心轴移动)。
具体的，在转盘53转动的过程中，由于第一滑槽531的一端与所述中心轴52之 间的距离，大于，第一滑槽531的另一端与所述中心轴52之间的距离，因此第一滑槽531能够带动第一连接件511远离中心轴或者朝向中心轴移动，从而带动第一导轨51和其中一个塞头41伸出于底座或收缩在底座上。而且由于第二滑槽532的一端与所述中心轴52之间的距离，大于，所述第二滑槽532的另一端与中心轴52之间的距离，因此第二滑槽532能够带动第二连接件551远离中心轴或者朝向中心轴移动，从而带动第二导轨55和另一个塞头42伸出于底座或收缩在底座上。
其中，在实际应用中，第二连接件可以为销钉。
可选的，在实际应用中，若打磨工件的两个孔位相对设置在打磨工件的两侧，则相应的，所述第一导轨和所述第二导轨分别设置在所述转盘相对的两侧。
需要说明的是，在本发明的其他实施例中，伸缩组件还可以通过其他结构实现，例如转盘上设置与导轨连接的弹簧，转盘在转动过程中弹簧收缩，在停止转动后弹簧恢复原状，使得塞头伸入孔位中，本发明对此并不限定。
示例性的，若对手机外壳的分型线进行打磨时，手机外壳具有耳机孔和USB孔，则相应的塞头的数量为两个，而且位置与耳机孔和USB孔在手机外壳的位置相对应，例如手机孔和USB孔分别设置在手机外壳相对的两侧。
在打磨前，通过操作手柄控制转盘转动，从而控制两个塞头收缩在底座上，具体的，如图6所示，若此时两个塞头并未收缩在底座上，则将操作手柄朝下扳动，使得转盘向逆时针方向转动，则使得第一滑槽531也随着转盘向逆时针方向转动，由于第一滑槽531的第一端5311与中心轴的距离较近，则第一连接件511朝向中心轴向下移动，第一导轨51带动其中一个塞头41往底座内部收缩，收缩后的状态如图7所示。如图6所示，此时第二滑槽532与第一滑槽531相对设置，则转盘向逆时针方向转动时，使得第二连接件朝向中心轴向上移动，则第二导轨55带动另一个塞头42往底座内部收缩，收缩后的状态如图7所示。
在打磨时，通过操作手柄控制转盘转动，从而控制两个塞头分别伸入手机外壳的耳机孔和USB孔中，具体的，如图7所示，此时两个塞头收缩在底座上，则将操作手柄朝上扳动，使得转盘向顺时针方向转动，则使得第一滑槽531也随着转盘向顺时针方向转动，由于第一滑槽531的第二端5312与中心轴的距离较远，则第一连接件511远离中心轴向上移动，第一导轨51带动其中一个塞头41向耳机孔中伸入，伸出后的状态如图6所示。如图7所示，此时第二滑槽532与第一滑槽531相对设置，则转盘向顺时针方向转动时，使得第二连接件远离中心轴向下移动，则第二导轨55带动另一个塞头42向USB 孔中伸入，伸出后的状态如图6所示。
因此，在打磨过程中，不容易将耳机孔和USB孔的孔位边缘打塌陷，而且也能够将耳机孔和USB孔的孔位边缘的分型线打磨干净。
上述具体实施方式中，通过转盘的转动，带动第一导轨、第二导轨以及分别与之连接的塞头伸缩，从而能够在对打磨工件进行打磨时，可以控制塞头伸入打磨工件的孔位中，对孔位起到支撑作用，因此不容易将打磨工件的孔位边缘打塌陷，而且也能够将打磨工件的孔位边缘的分型线打磨干净。
图8为本发明实施例提供的仿形底座另一实施例的结构图。在上述实施例的基础上，如图8所示，本实施例的仿形底座，还包括：
塞头座6；其中，所述塞头座6沿所述塞头的延伸方向设有通孔，所述塞头设置在所述通孔中，所述塞头座固定在所述伸缩组件上。
具体的，由于打磨工件时会对塞头造成磨损，因此在设置塞头时将塞头的长度设置为大于孔深的长度，在磨损之后，可以将塞头从塞头座中拔出与磨损长度相应的长度。
塞头座固定在伸缩组件上，如固定在伸缩组件的导轨上。塞头座沿塞头的延伸方向设有通孔，塞头容纳在通孔中。
可选的，所述塞头座上设有与所述塞头垂直的限位螺钉，所述限位螺钉用于将塞头固定在所述通孔中。
具体的，为了使得塞头在使用过程中，可以根据实际情况设置伸出于塞头座的不同长度，因此在塞头座上固定有与塞头垂直的限位螺钉，用于将塞头固定在通孔中。
在另外一个实施例中，塞头座6沿所述塞头的延伸方向设有凹槽61，所述塞头设置在所述凹槽中，所述塞头座固定在所述伸缩组件的导轨上。
上述具体实施方式中，通过塞头座对塞头的固定，使得塞头在磨损之后，可以将塞头位于塞头座外部的部分伸长，从而不影响对孔位的支撑。
在上述实施例的基础上，如图8所示，本实施例的仿形底座，还包括：
底盖7；其中，所述底盖7与所述底座3相匹配，盖设在所述底座3上。
具体的，底盖7盖设在底座3上，与打磨工件的外形匹配，伸缩组件设置在底盖7和底座3的容纳空间中。
其中，在实际应用中，底盖上部可以设有通孔，通孔用于容纳塞头座和塞头。
可选的，所述塞头为金属材料制成的。
其中，在实际应用中，所述金属材料可以为钨钢。
具体的，为了防止塞头磨损，可以选用钨钢，钨钢的硬度较大，不容易磨损。
上述具体实施方式中，塞头的材料可以选用钨钢，由于钨钢的硬度较大，可以防止塞头磨损。
本发明实施例中还提供一种打磨治具，包括：如上述仿形底座任一项实施例所述的仿形底座。
可选的，本实施例的打磨治具还可以包括：打磨头等其他部件。
本实施例提供的打磨治具，其实现原理及技术效果与上述仿形底座任一项实施例所述的类似，此处不再赘述。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
