技术领域
本发明涉及一种管端加工设备，特别是一种用于汽车排气歧管管端成型的多工位管 端加工设备。 背景技术
汽车排气歧管是一种形状复杂多样的异形管件结构，其作用是使废气在管道内产生 涡流， 能够强制性地驱出废气， 并且提高排气速度。 由于排气歧管为非规则形状， 通常 排气歧管的两端管口形状也不相同，传统排气歧管的管口加工过程一般需要多道工序才 能完成， 每个工序都需要经过一次夹装， 费时费力， 加工精度和效率低。
为了提高异形管件的管口加工效率， 现有技术有专利号为 ZL201120068846.0(公告 号为 CN202070626U)的中国实用新型《多工位歧管管端成型装置》公开了这样一种汽车 零件的加工装置， 该装置包括有一对可相互对合的上模和下模， 上、 下模对合后形成一 个与待加工的歧管形状相适应、 并可夹持固定歧管的内腔； 下模的基体上固定安装有四 个液压缸支架， 每个液压缸支架上安装有一个液压缸， 四个液压缸的伸缩部分分别驱动 一个圆形管端定径模头、 一个圆形管端切割模头、一个异形管端成型模头和一个异形管 端切割模头。
上述专利通过一次夹装可以实现多个工位的加工，使得整个歧管的管端成型在一个 工序中即可一次完成， 避免了多次定位造成的定位误差。 但是， 上述专利的上模和下模 对合后每次只能装夹一个歧管， 无法实现多个歧管同时进行管端加工的需求； 而且， 上 模和下模所形成的内腔只能适用于一种待加工歧管的形状，无法加工其他不同管径与形 状的歧管， 若要加工其他形状的歧管则需要更换另一台设备或者更换上、 下模， 对于汽 车管件的生产厂家来说， 不同规格的歧管就需要对应不同的管端加工设备， 每个设备的 加工对象单一， 设备利用率低， 投入成本高， 无法达到高效经济化的管端自动化加工要 求， 还 ¾寺于作进一步的改进。 发明 容
本发明所要解决的技术问题是针对上述现有技术现状而提供一种夹装方便、加工效 率高并且可同时加工不同管径与形状的管件的多工位管端加工设备。 本发明解决上述技术问题所采用的技术方案为：一种多工位管端加工设备，包括有 机座和安装在该机座上的刀架， 其特征在于： 所述刀架包括有竖直设置的固定板和可转 动地连接于该固定板上的刀盘， 所述刀盘上沿周向安装有多把刀具；
所述机座在所述刀架的正前方还设置有管件夹持装置，该管件夹持装置包括有带至 少两个工作位的工作台， 每一工作位上设置有模具， 所述模具开设有可固定待加工管件 的模腔， 并且， 所述机架上还设置有可驱动所述刀架沿靠近或远离所述工作台的方向做 直线运动的主驱动装置。
刀盘相对于固定板的转动可以通过现有技术中的各种结构实现，为了使得刀架的结 构更为紧凑， 减少刀架的体积， 作为优选， 所述刀盘和所述固定板之间设置有第一转盘 轴承， 其中， 所述的第一转盘轴承包括有外座圈和内齿圈， 所述外座圈可转动地套设连 接于所述内齿圈之外， 所述外座圈与所述固定板固定相连， 所述内齿圈与所述刀盘固定 相连， 所述刀架上还设置有能驱动所述内齿圈旋转的第一驱动装置。
作为优选，所述的第一驱动装置简单地可以第一电机，所述第一电机具有能与所述 内齿圈相啮合的第一齿轮轴。
为了保证刀具连接的可靠性， 防止刀具在工作中， 刀体发生转动， 作为优选， 所述 的刀具包括有刀头、 刀体和刀柄， 所述刀体和刀柄固定连接为一体， 所述刀盘的正面开 设有可供所述刀柄插入的刀具安装孔，所述刀盘的圆周面在对应每一刀具的位置开设有 沿径向布置的通孔， 所述通孔内插设有能与所述刀柄相抵而防止所述刀体转动的限位 销。于是，采用限位销和刀柄相抵配合方式， 不仅可以实现刀体的固定， 防止刀体转动， 而且还方便刀具的安装和拆卸， 更加节省刀具更换的时间。
为了提高限位销和刀柄的接触摩擦力， 进一步提高定位可靠性， 作为优选， 所述刀 柄上成型有平面， 该平面上设置有锯齿状凸起， 所述限位销上成型有斜面， 该斜面上设 置有能与所述锯齿状凸起相配合限位的齿槽。
考虑到刀具的种类有多种多样， 对于钻孔加工类的刀具， 在加工过程中， 刀头是可 转动地设置于刀体上的， 为了驱动刀头的转动， 作为优选， 所述刀柄的底部还设置有能 驱动所述刀头一起转动的齿轮， 所述刀盘和所述固定板之间设置有第二转盘轴承， 所述 第二转盘轴承包括有内座圈和外齿圈， 所述外齿圈可转动地套设连接于所述内座圈之 外， 所述内座圈与所述固定板固定相连， 所述外齿圈与所述刀盘固定相连， 并且， 所述 刀具的齿轮与所述外齿圈相啮合，所述刀架上还设置有能驱动所述外齿圈旋转的第二驱 动装置。 于是， 当第二驱动装置工作时， 通过第二转盘轴承的外齿圈可以带动与该外齿 圈相啮合刀具的刀头旋转， 实现钻孔加工。
作为优选，所述的第二驱动装置也可以简单地选择为第二电机，所述第二电机具有 能与所述外齿圈相啮合的第二齿轮轴。
为了保证刀盘的转动定位精度， 防止在加工过程中刀盘相对于固定板发生转动偏 移， 作为优选， 所述刀盘的圆周面上在对应每一刀具的位置还分别设置有一感应器， 所 述固定板的圆周面上设置有一能分别与每一所述的感应器对应接触的感应触头，所述固 定板和刀盘之间还设置有当所述感应触头和感应器对应接触的状态下防止所述刀盘相 对于固定板转动的锁定装置。 于是， 感应器和感应触头的配合能够检测刀盘是否转动到 位， 在转动到位的时候， 感应装置会发送信号给锁定装置， 进而将刀盘和固定板进行固 定， 防止加工过程中刀盘的偏移， 提高加工精度和质量。
考虑到加工方便和结构简单， 作为优选， 所述的锁定装置包括有液压缸， 所述固定 板的正面开设有第一定位孔，所述刀盘的正面沿周向开设有多个能分别与所述第一定位 孔相对齐的间隔设置的第二定位孔，所述第二定位孔的间隔角度为所述刀具沿所述刀盘 分布的间隔角度， 在所述感应触头和感应器对应接触的状态下， 所述液压缸的活塞杆穿 过相互对齐的第一定位孔和第二定位孔而实现所述固定板和刀盘的固定连接。当刀盘转 动到位后， 感应信号触发液压缸动作， 液压缸控制活塞杆插入相互对齐的第一定位孔和 第二定位孔之内， 从而实现刀盘和固定板的固定连接， 当刀盘要继续转动时， 液压缸控 制活塞杆缩回， 刀盘又可以相对于固定板实现转动。
可以釆用现有技术中的各种设备来驱动刀架做直线移动，如齿轮齿条、滑块导轨等， 作为优选， 所述的主驱动装置可以采用以下结构实现： 其包括有第三电机、 丝杠轴和推 板， 所述第三电机的输出端与所述丝杠轴相连并能驱动该丝杠轴旋转， 所述刀架沿轴向 开设有可供所述丝杠轴穿过的轴孔， 所述推板固定连接在所述刀架的固定板上， 所述推 板开设有能与所述轴孔相对应的中心孔， 该中心孔内设置有能与所述丝杠轴相配合的丝 杠螺母。 于是， 第三电机带动丝杠轴转动， 丝杠轴和推板上的螺母配合进而驱动整个刀 架实现沿直线方向的移动， 控制精度高， 结构简单， 容易实现。
与现有技术相比， 本发明的优点在于： ' 首先， 采用了转塔式结构的刀架， 整个刀架相对于机座竖直设置， 所有刀具均设置 在刀盘的同一侧面上， 装卸更加方便；
其次， 刀盘为可转动结构，一次可以安装多把不同功能的刀具， 只要转动刀盘即可 实现换刀， 省去了每加工一个工序需要换一次刀具的麻烦， 节省了刀具更换的时间， 提 高了加工效率；
再者，刀架前方设置有多工位的工作台，每个工作位上安装有可以对应夹装一种尺 寸规格管件的模具， 同一工作台可以同时夹装多个不同管径与形状的管件， 也可以同时 夹装多个相同规格的管件， 再配合转塔式刀架， 刀架在对应不同管件的位置安装不同规 格的刀具， 可以实现多个管件同步加工的目的， 提高设备利用率， 满足集成化加工的要 求；
另外，工作台上若夹装有多个同规格的管件，可以一次夹装后，通过刀盘的转动 (更 换不同的刀具)和模具的换位来进行各管件按工序步骤的依次加工， 从而实现管件加工 的流水线操作， 减少因多次夹装引起的加工误差， 提高管件的加工精度。 附图说明

本实施例的刀架 3采用转塔式结构， 该刀架 3包括有竖直设置的固定板 31和可转 动地连接于该固定板 31上的刀盘 32，刀盘 32上沿周向安装有多把用于管件端面加工的 刀具 6, 刀架 3上还设置有可驱动刀架 3沿靠近或远离工作台 2的方向做直线运动的主 驱动装置， 该主驱动装置包括有第三电机 53、 丝杠轴 521和推板 522， 刀架 3沿轴向开 设有可供丝杠轴 521穿过的轴孔，推板 522固定连接在刀架 3的固定板 31上，推板 522 开设有能与轴孔相对应的中心孔，该中心孔内设置有能与丝杠轴 521相配合的丝杠螺母， 第三电机 53的输出端与丝杠轴 521相连并能驱动该丝杠轴 521旋转，第三电机 53启动 后， 通过丝杠轴 521和丝杠螺母的配合能够推动整个刀架 3沿轴向做直线移动， 进而调 整刀架 3相对于待加工管件之间的距离。
本实施例的刀盘 32为可转动地连接在固定板 31上， 为了实现刀盘 32的可转动控 制， 刀盘 32和固定板 31之间设置有第一转盘轴承 4， 其中， 第一转盘轴承 4包括有外 座圈 41和内齿圈 42，外座圈 41可转动地套设连接于内齿圈 42之外，外座圈 41与固定 板 31固定相连， 内齿圈 42与刀盘 32固定相连， 刀架 3上还设置有能驱动内齿圈 42旋 转的第一驱动装置， 该第一驱动装置为第一电机 51， 第一电机 51的输出端设置有能与 内齿圈 42相啮合的第一齿轮轴 51。

通常， 管件端面的加工包括有多种不同的工序， 对于实现扩口、缩口等这类管端加 工的刀具 6来说， 刀具 6的刀头 61在加工过程中是不旋转的， 安装刀具 6时只要将刀 体 62固定在刀盘 32上即可；
而对于管端钻孔加工来说， 刀头 61在加工过程中要连续旋转， 这类刀具 6的刀柄 63在底部还设置有能驱动刀头 61—起转动的齿轮 64，刀盘 32和固定板 31之间设置有 第二转盘轴承 8， 该第二转盘轴承 8包括有内座圈 81和外齿圈 82， 外齿圈 82可转动地 套设连接于内座圈 81之外， 内座圈 81与固定板 31固定相连， 外齿圈 82与刀盘 32固 定相连， 刀具 6的齿轮 64与外齿圈 82相啮合， 刀架 3上还设置有能驱动外齿圈 82旋 转的第二驱动装置， 该第二驱动装置为第二电机 52， 第二电机 52具有能与外齿圈 82 相啮合的第二齿轮轴 521 ; 并且， 为了使得结构更加紧凑， 方便装配， 第二转盘轴承 8 的外齿圈 82直径小于第一转盘轴承 4的内齿圈 42直径，第二转盘轴承 8可以整个容置 于第一转盘轴承 4的内齿圈 42之中， 参见图 4。
为了保证刀盘 32转动过一个角度后定位更加准确， 同时防止在加工过程中， 刀盘 32发生转动偏移， 本实施例的刀架 3上还设置有电子感应锁定装置， 具体结构为： 刀盘 32的圆周面在对应每一刀具 6的位置分别设置有一感应器 323， 固定板 31在圆周面上 设置有一个能分别与每一感应器 323对应接触的感应触头 311 ;
固定板 31和刀盘 32之间还设置有锁定装置， 该锁定装置包括有两个液压缸 54， 固定板 31的正面沿任意一条径线方向的两端各开设有第一定位孔 312，每个第一定位孔 312的位置安装有一个液压缸 54， 刀盘 32的正面沿周向则开设有多个能分别与第一定 位孔 312相对齐的间隔设置的第二定位孔 324， 第二定位孔 324的间隔角度为刀盘 32 上的刀具 6沿周向分布的间隔角度； 为了提高连接可靠性， 同时方便磨损更换， 在每个 第一定位孔 312内设置有第一轴套 541，在每个第二定位孔 324内设置有第二轴套 542， 当感应触头 311和任意一个感应器 323相对接触的状态下， 电子感应开关导通， 并发送 信号给两个液压缸 54， 每个液压缸 54的活塞杆 543伸出并穿入相对齐的一组第一定位 孔 312的第一轴套 541和第二定位孔 324的第二轴套 542中， 从而实现刀盘 32和固定 板 31之间的锁定， 感应器 323和感应触头 311能够检测刀盘 32是否转动到位， 提高刀 盘 32转动的准确性， 锁定装置能够在刀盘 32转动到位后实现刀盘 32的固定， 防止刀 具 6偏移， 保证刀具 6工作的精度 (管端圆度加工精度能保证在 0.05mm内)和可靠性， 提升管件的产品加工质量。 本实施例的管端加工设备的工作原理为：
首先将待加工的管件安装在工作台两个工作位对应的模具 21上，每副模具 21的模 腔形状可以根据具体加工需要确定， 当需要同时对不同管径和大小的管件进行管端加工 时， 此时， 两个工作位上安装具有不同模腔形状的模具； 当需要批量加工多个同种规格 的管仲时， 则两个工作位上安装相同模腔形状的模具 21 ;
启动第三电机 53，通过丝杠轴 521和推板 522内的丝杠螺母的配合驱动整个刀架 3 沿机座 1做直线移动， 并控制刀架 3运动至相对于工作台 2的合适位置； 根据待加工管 件的管端加工要求，启动第一电机 51，控制刀盘 32转动并使得刀盘 32上的刀具 6对准 所需要加工的各管件， 当刀盘 32转动到位后， 第一电机 51停止工作， 感应器 323和对 应的感应触头 311对齐， 并发送电子信号给液压缸 54， 液压缸 54的活塞杆 543伸出并 将固定板 31和刀盘 32固定于一体； 然后， 夹持在工作台 2上的每一管件对应一把刀具 6进行管端加工， 如果是进行钻孔加工， 则可以启动第二电机 52， 通过第二电机 52和 第二转盘轴承 8的配合驱动刀头 61旋转。
利用本实施例的管端加工设备进行管件加工， 只需要进行一次工件 (待加工管件)夹 装和一次刀具 6夹装， 就可以实现多道工序的连续加工， 在加工过程中， 可以通过刀盘 32的旋转来更换刀具 6， 以实现在同一工件上的不同工序的连续加工， 也可以通过翻转 模具 21的上模座 212和下模座 211，来更换工件的待加工管端，以减少工件夹装的时间， 并能够降低因多次夹装引起的加工误差。 本实施例的刀盘 32上可以安装可转动的动力头， 也可以同时安装螺纹车刀与攻牙 丝锥， 在整个加工工艺过程中， 无需更换刀头 61， 即可实现管件的多工序流连续加工； 其次， 本实施例的工作台 2上设置有双工作位， 每个工作位上安装有模具 21， 实现多工 位同时加工的目的； 另外， 本实施例中的主驱动装置 (第三电机 53)为一伺服电机， 该伺 服电机产生的轴向推力可以实现在 0.1吨〜 70吨之间的调节，整台设备上的第一电机 51、 第二电机 52、 第三电机 53、 液压缸 54和油缸的控制都可以通过数控编程进行控制， 管 件夹持装置的工作台 2前部还可以安装切割机， 工件和刀具 6在一次夹装后可以连续进 行切割、 扩口、 缩口、 翻边、 卷边、 钻孔、 拔孔、 旋压、 墩头和旋沟等等一系列管端加 工功能， 节省了装夹时间， 大大提髙了加工效率， 管端加工的各种功能都能够通过本实 施例的一台设备实现， 集成化程度高， 有利于数控自动化成产。
