Description

一种摆动工具用多功能快速装配安装孔 技术领域
本发明属于电动工具技术领域，具体是指一种摆动工具用多功能快速装配安装孔。
背景技术
在工业技术日新月异的今天，工业技术的不断发展，各种电动工具越来越多，已经渗透到众多领域，例如：切割、打磨抛光、修剪、钻孔等等。这些电动工具通常包括驱动电机和驱动电机相连接的传动装置以及由传动装置驱动的工具头，不同结构的工具头有不同的使用功能，以往人们使用的工具头，不具备快速装配功能，更换不同功能的工具头很是麻烦，不仅浪费时间以及工具材料，而且劳动生产率极低，同时还不便于存放，常见的工具头包括直锯片、圆锯片、三角形磨砂盘、刮刀等，可以实现如锯、切、磨、刮等工作需求。后来人们将工具头设计成可拆卸的结构，通过更换工具头，来获得不同的功能，不但大大的节约了时间和工具材料，还能便于存放，而且外出工作时亦可方便携带。目前不同的工厂使用不同规格的孔型接口，使得配套的工具品种繁多，用户在使用时购买配件极其不便，不但浪费消费者选购的时间，而且在使用不同工厂的产品配件不容易采购。
发明内容
为解决上述现有难题，本发明提供了一种实用性高、结构简单、携带方便、快速装配、适用范围广，适用于多种机器连接方式的摆动工具用多功能快速装配安装孔。
本发明采取的技术方案如下：本发明摆动工具用多功能快速装配安装孔，包括装配底板、折弯过渡段和工具头连接板，所述折弯过渡段设于装配底板与工具头连接板之间，所述折弯过渡段倾斜设置，折弯过渡段与装配底板、工具 头连接板之间圆弧过渡，折弯过渡段使得工具头连接板与装配底板存在高度差，避免机器运转时，工具头干涉机器的其他部件，保证机器及工具头工作运行平稳；所述装配底板上设有装配定位凸台一和快装定位凸台二，所述快装定位凸台二的中心处设有快装通孔，所述装配底板的一侧设有与快装通孔贯通相连的避空开口，所述装配底板上设有贯穿装配底板与快装定位凸台二且与快装通孔贯通相连的限位避空通孔，所述限位避空通孔对称设于快装定位凸台二的两侧，所述避空开口对称设于快装定位凸台二的两侧，所述快装通孔两侧对称设有与快装通孔贯通相连的内侧限位孔；所述快装定位凸台二上壁开设有外侧定位孔，所述外侧定位孔绕快装通孔中心呈花形矩阵阵列分布；所述装配定位凸台一呈下端开口的正棱台设置，所述装配定位凸台一上壁设有上下贯通的中心孔以及与中心孔贯通相连的花型孔，所述花型孔沿中心孔边沿等间距圆周分布，所述装配定位凸台一侧壁设有与装配定位凸台一贯通相连的中空的弧形凸起。
进一步地，所述装配定位凸台一的上顶面的边的数量为6-24条，使得装配定位凸台的结构更加稳固，同时对摆动锯锯轴固定更加牢固，并增加对机器和锯片之间装配的稳定性；所述中心孔的直径为6-15mm，所述花型孔的数目为4-12个，所述弧形凸起的厚度为3-6mm，对摆动锯锯轴起到限位固定作用。

实施例二：如图5所示，所述工具头连接板3也可设于装配底板1的两侧边上，便于连接圆锯片。
如图6所示，在一种实施例中，所述设于快装通孔6中部两侧的两个内侧限位孔10可以与外侧定位孔11互相连通，以便更好的对摆动锯锯轴进行定位 安装，且固定更加牢固。
具体使用时，根据不同工况将工具连接板通过焊点凹槽19以焊接方式或者以铆接方式与不同工具头进行固定连接；如图4所示，工具头连接板3可以设于装配底板远离避空开口的一侧侧边上并通过焊接或铆接的方式连接固定直锯片；如图5所示，工具头连接板3也可设于装配底板的两侧边上并通过焊接或铆接的方式连接固定圆锯片；然后根据不同形状安装孔形选择不同的安装固定方式，对于通过螺母固定的摆动锯，将摆动锯的锯轴上的螺母拧松，然后将摆动锯的锯轴通过避空开口7插入快装通孔6内，通过快装安装孔9和内侧限位孔10对摆动锯锯轴进行限位安装，再次旋紧锯轴上的螺母使得装配底板1被固定在螺母和摆动锯之间，实现工具头的快速安装，对于通过环形排列的凸台进行固定的摆动锯，将外侧定位孔11对准摆动锯上的凸台插入，使得工具头稳固固定在摆动锯上，避免产生错位，采用多角度限位，保证了操作的安全性和稳定性，对于通过摆动锯上的涨紧心轴固定的摆动锯，只要用手捏紧摆动式电动工具上捏手的主体插入中心孔12后松开摆动锯上的涨紧心轴，就能方便、快捷、轻松的实现更换。
本发明的多功能摆动式快装工具头，可配置各种不同形状的安装孔形，遇到不同工况、或所锯割的材料软、硬不一致时，更换不同技术参数的工具头，就能拓展摆动式电动工具的使用空间，实现全方位，多角度的锯割，极大的提高了电动工具的利用率，并且在更换摆动锯上的工具头时具有快装功能，由于采用多角度限位，保证了操作上的安全性和稳定性，具有快装功能的工具头，在更换时，只要用手捏紧摆动式电动工具上捏手的主体，松开摆动锯上的涨紧心轴，就能方便、快捷、轻松的实现更换，无需将螺母从锯轴上全部旋下，通过避空开口7以插拔的方式实现快速安装，方便快捷，适用于多种安装孔形， 通用性强，摆动式工具头材质全部为钢性材质，实际操作时，由于工具头重量小，刚性强，可大大的提高电动工具的便用寿命以及实际操作上的整体安全性能，真正实现一次性快速、方便、安全切割完成。
需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。
