Description

一种自动清洁的机床
本申请要求于2023年01月17日提交中国专利局、申请号为202310084659.9，发明名称为“一种自动清洁的机床”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及机床清洁技术领域，特别是涉及一种自动清洁的机床。
 背景技术
机床在加工工件的过程中会产生大量的废屑以及粉尘颗粒，不仅会损坏设备，影响机床加工的精度和使用寿命，而且产生的废屑和粉尘会污染车间环境，严重影响工作人员的身体健康。为解决这个问题，通常会在机床内设置对准加工刀具与加工工件的吸尘装置，并通过管路与机床外的集尘器连通，以收集加工过程产生的废屑和粉尘颗粒。然而，当切削时会产生较大粒径的废屑和粉尘颗粒时，废屑和粉尘颗粒会飞溅至工作台附近，并粘附在机床工作区域的工作面上，此时吸尘装置很难将其吸附去除，于是便会逐渐在工作台附近堆积结垢，难以清理。

传统的机床的工作区域内通常具有一工作面，该工作面上设有工作台，该工作台与工作区域的工作面滑动连接，并可在工作面上直线滑动。采用机床加工工件时，通常会将待加工工件放置在工作台上，然后通过刀具对待加工工件进行加工。通过长期的工件加工生产实践，本申请人发现工作台附近的工作面是较大粒径废屑和粉尘颗粒飞溅并堆积的集中区域，因此，本申请提供一种能自动清洁的机床，可自动清洁在加工过程中产生并飞溅至工作台附近的废屑和粉尘颗粒。
图1‑3示出了本申请自动清洁的机床一种实施方式的具体结构。如图1‑3所示，本实施方式中自动清洁的机床包括机身（图未示），以及设置在机身的工作面（图未示）上的工作台10和清洁机构20。工作台10具体为矩形体，用于承载待加工工件。工作台10位于与工作面（图未示）滑动连接，使得工作台10可在工作面（图未示）上沿第一方向D1往复运动。清洁机构20包括集尘槽200以及吸尘组件202，在本实施方式中，集尘槽200和吸尘组件202的数量均为两个。两集尘槽200具体为槽口朝上的半闭合矩形结构，两相互平行的集尘槽200固定在机身（图未示）的工作面（图未示）上，并分别位于工作台10沿第二方向D2的相对两侧，且集尘槽200的延伸方向与第一方向D1平行。两吸尘组件202分别通过支架201固定在工作台10沿第二方向D2的相对两侧，每一吸尘组件202分别对应一集尘槽200。吸尘组件202位于集尘槽200的槽口上方，用于吸附集尘槽200内堆积的废屑和粉尘颗粒。其中，第一方向D1与第二方向D2之间的夹角为90°。
具体地，吸尘组件202包括中空的吸尘管2020和三个与吸尘管2020连通的吸尘盒2022。吸尘管2020两端为封闭端，两吸尘组件202的吸尘管2020通过支架201分别固定在工作台10沿第二方向D2的两相对侧，且吸尘管2020的轴心与第一方向D1平行。吸尘管2020一端设有与吸尘管2020管腔连通的集尘口2020a ，该集尘口2020a用于与集尘器（图未示）连接。三个吸尘盒2022间隔固定在吸尘管2020的底部，并伸入集尘槽200内。吸尘盒2022的顶部具有连通吸尘管2020管腔的连接口2022a，其底部具有吸尘口2022b，吸尘口2022b正对集尘槽200的槽底，且吸尘口2022b与集尘口2020a连通。
在这里，工作台10与机身的工作面（图未示）滑动连接的方式可以通过导轨与滑块的配合滑动，具体为导轨设置在工作面，导轨的延伸方向与第一方向D1平行，工作台10固定在滑块顶部，通过驱动电机或伸缩气缸驱动工作台10沿导轨滑动，以实现工作台10沿第一方向D1滑动；也可以通过丝杆与丝杆滑块的配合滑动，具体为丝杆固定设置正在工作面，且丝杆的延伸方向与第一方向平行，丝杆滑块套接在丝杆上，工作台10固定在丝杆滑块顶部， 丝杆的一端与驱动电机连接，通过驱动电机驱动丝杆绕轴心转动，带动丝杆滑块沿丝杆的轴向滑动，这样同样可实现工作台10沿第一方向D1滑动。
由于通过机床加工的过程中会产生大量的废屑以及粉尘颗粒，这些废屑和粉尘颗粒会飞溅至工作台10附近的区域内，因此便会落入位于工作台10两侧的集尘槽200内。当完成加工需要清洁时，启动集尘器（图未示），并同时驱动工作台10沿第一方向D1往复运动。由于吸尘组件202是固定在工作台10上，因此工作台10的往复运动将带动吸尘盒2022在集尘槽200内沿第一方向D1来回移动，从而将集尘槽200内堆积的废屑和灰尘通过吸尘盒2022、吸尘管2020，最后收集至集尘器（图未示）内。
虽然通过吸尘组件202产生的吸附力可以清除收集于集尘槽200内的废屑和粉尘颗粒，但由于其清洁程度取决于集尘器(图未示)的吸附力大小。对于集尘槽200内的颗粒较大的废屑或在集尘槽200内堆积结垢的粉尘颗粒，如果集尘器（图未示）产生的吸附力不足时，就无法将其吸附去除。
作为对上述技术方案的优化方案，上述自动清洁的机床还包括设置在吸尘盒2022 上的清扫组件204。图4‑5示出了清扫组件与吸尘组件的连接关系。具体地，集尘槽200一端的槽底设有排屑口200a；清扫组件204包括毛刷2040，毛刷2040设置在吸尘盒2022正对排屑口200a的侧部，毛刷2040的刷毛2040a伸入集尘槽200内，并与集尘槽200的槽底接触。通过利用工作台10沿第一方向D1往复运动，带动毛刷2040在集尘槽200内来回移动，在移动的过程中，毛刷2040将堆积在集尘槽200槽底或槽壁上的结垢物刮下，对堆积物或结构物脱落后形成的粒径较小、质量较轻的废屑或粉尘颗粒，则通过吸尘盒2022收集于集尘器（图未示）内；而对于粒径较大、质量较重的废屑或粉尘颗粒，由于无法通过吸尘组件202的吸附作用被去除，因此在毛刷2040的清扫作用下，移至集尘槽200的排屑口200a，通过排屑口200a排出。
进一步地，清扫组件204还包括转轴2042。吸尘盒2022正对排屑口200a的侧部具有向外倾斜的倾斜面，吸尘盒2022正对排屑口200a的侧部上设有转轴固定座2024，转轴2042贯穿毛刷2040的刷柄2040b，并固定在转轴固定座2024上，毛刷2040通过转轴2042与吸尘盒2022转动连接，吸尘盒2022的倾斜面与毛刷2040抵接，为毛刷2040提供指向排屑口200a的支撑力，使得毛刷2040所在平面与集尘槽200的槽底之间的夹角小于或等于90°，且毛刷2040可相对于吸尘盒2022的侧部向上转动。优选地，吸尘盒2022沿第二方向D2的截面外周边为上窄下宽的梯形，这样既能给毛刷2040提供向前的支撑力，同时还增大吸尘口2022b的面积，有利于同一时间吸附更多的废屑和粉尘颗粒物。集尘槽200槽底间隔设有凸起结构2000，每一凸起结构2000对应一清扫组件204，凸起结构2000位于工作台10未向排屑口200a移动、毛刷2040处于初始位置时在集尘槽200槽底的正投影沿朝排屑口200a方向的前端。如此，每一集尘槽200的槽底均设有三组沿第一方向D1间隔排列的凸起结构2000，这三组凸起结构2000中，距离排屑口200a最近的为第一凸起结构，沿第一方向D1与之相邻的为第二凸起结构，而距离排屑口200a最远的为第三凸起结构。以这三组凸起结构2000为界，将集尘槽200分为四个区域，其中，距离排屑口200a最近的区域为第一区域，与第一区域相邻的区域为第二区域，第二区域远离排屑口200a一侧并与之相邻的区域为第三区域，而距离排屑口200a最远的区域为第四区域。而与第一凸起结构对应的毛刷2040为第一毛刷，与第二凸起结构对应的毛刷2040为第二毛刷，而与第三凸起结构对应的毛刷2040为第三毛刷。
其中，图6‑7示出了本申请自动清洁的机床中集尘槽内凸起结构的第一种实施方式。如图6‑7所示，在该实施方式中，凸起结构2000为沿第二方向D2并列设置在集尘槽200槽底的两凸块。清洁开始前，三个毛刷均处于初始位置，具体为，第一毛刷位于第二区域靠近第一凸起结构的位置，第二毛刷位于第三区域靠近第二凸起结构的位置，而第三毛刷位于第四区域靠近第三凸起结构的位置。
清洁开始时，工作台10沿第一方向D1移动，同时带动同一吸尘组件202中的三个毛刷2040同时向排屑口200a的方向移动，在毛刷2040移动的过程中，每一个毛刷2040都如扫把一般将集尘槽200对应区域内的废屑以及粉尘颗粒扫向接近排屑口200a的方向。由于吸尘盒2022抵接毛刷2040，为毛刷2040提供一个向前的支撑力，且毛刷2040的刷毛2040a时是散开的，因此当毛刷2040碰触到凸起结构2000时，凸起结构2000可从刷毛2040a之间穿过。当第一毛刷越过第一凸起结构，进入第一区域，会将第一区域内的废屑和粉尘颗粒物直接扫入排屑口200a内，这部分废屑和粉尘颗粒通过排屑口200a排出机床外部。当第一毛移向排屑口200a的同时，第二毛刷也会越过第二凸起结构，进入第二区域，此时，随着工作台10 向排屑口200a的方向移动，第二毛刷将第二区域内的废屑和粉尘颗粒扫向第一区域内；当第二毛刷越过第一凸起结构，会将原来在第二区域内的废屑和粉尘颗粒带至第一区域靠近第一凸起结构的位置。同理，当第一毛刷越过第一凸起结构、第二毛刷越过第二凸起结构时，第三毛刷也会越过第三凸起结构，进入第三区域，此时，随着工作台10向排屑口200a的方向移动，第三毛刷将第三区域内的废屑和粉尘颗粒扫向第二区域内；当第三毛刷越过第二凸起结构，会将原来在第三区域内的废屑和粉尘颗粒带至第二区域靠近第二凸起结构的位置。
当第一毛刷将第一区域内的废屑和粉尘颗粒扫入排屑口200a后，工作台10无法再向前行，此时，工作台10则向背向排屑口200a的方向移动。由于毛刷2040可绕转轴2042相对于吸尘盒2022向上转动，因此，当第一毛刷碰触到第一凸起结构，第一毛刷被第一凸起结构抬起，使其刷毛2040a不再与集尘槽200的槽底接触，这样就避免将从第二区域带至第一区域的废屑和粉尘颗粒又被第一毛刷重新扫至第二区域；当被抬起的第一毛刷完全越过第一凸起结构时，第一毛刷会向下旋转，使得其刷毛2040a会重新与集尘槽200的槽底接触，同时第一毛刷对应的吸尘盒2022的倾斜面又会重新抵接第一毛刷，如此，当工作台10再次向排屑口200a的方向移动时，可将从第二区域带至第一区域的废屑和粉尘颗粒物扫至排屑口200a。同理，随着工作台10沿背向排屑口200a的方向移动，当第二毛刷碰触到第二凸起结构以及第三毛刷碰触到第三凸起结构时，第二毛刷和第三毛刷分别被第二凸起结构和第三凸起结构抬起，使其刷毛2040a均不再与集尘槽200的槽底接触，则可避免从第三区域带至第二区域的废屑和粉尘颗粒又被第二毛刷重新扫至第三区域，也避免从第四区域带至第三区域的废屑和粉尘颗粒也被第三毛刷重新扫至第四区域；而当被抬起的第二毛刷完全越过第二凸起结构，被抬起的第三毛刷完全越过第三凸起结构时，第二毛刷和第三毛刷均会向下旋转，使得第二毛刷的刷毛2040a和第三毛刷的刷毛2040a又会重新与集尘槽200的槽底接触，而第二毛刷和第三毛刷对应的吸尘盒2022的倾斜面又会重新抵接第二毛刷和第三毛刷，如此，当工作台10再次向排屑口200a的方向移动时，又会将第四区域和第三区域内的废屑和粉尘颗粒物分别带至第三区域和第二区域，如此循环工作。
进一步地，上述凸起结构2000正对排屑口200a一侧的高度大于背向排屑口200a一侧的高度，优选地，如图8所示，该凸起结构2000沿第二方向D2的截面外周边为直角三角形，其中，凸起结构2000正对排屑口200a的侧面为垂直集尘槽200槽底的垂直面，而背向排屑口200a的侧面为倾斜面，这样有利于毛刷2040随工作台10向排屑口200a的方向移动时，凸起结构2000能顺利通过毛刷2040的刷毛2040a，同时，也有利于毛刷2040随工作台10向背向排屑口200a的方向移动过程中，当毛刷2040碰触到凸起结构2000时可迅速被抬起，避免废屑和粉尘颗粒被重新扫至上一区域。
通过上述三个毛刷对集尘槽200的分段清扫，并与对应的凸起结构2000配合，将距离排屑口200a最远的废屑和粉尘颗粒物逐段扫向排屑口200a，同时避免将上一区域内带来的废屑和粉尘颗粒物又重新扫回上一区域内，从而能对整个集尘槽200内的废屑和粉尘颗粒物进行清扫；此外，在各毛刷2040对集尘槽200清扫的过程中，每一个毛刷2040对应吸尘组件202在毛刷2040扫过废屑和粉尘颗粒后，也会将粒径较小、质量较轻的废屑和粉尘颗粒吸走。
图9示出了本申请自动清洁机床中集尘槽内凸起结构的第二种实施方式。如图9所示，凸起结构2000除了为上述沿第二方向D2并且设置的两凸块外，凸起结构2000还可以是沿第二方向D2延伸的凸台，且凸起结构2000的两端分别与集尘槽200的两相对的侧壁连接。在这种实施方式中，凸起结构2000正对排屑口200a一侧的高度大于背向排屑口200a一侧的高度。优选地，该凸起结构2000沿第二方向D2的截面外周边为直角三角形（与图8所示凸起结构的第一种实施方式的截面外周边相同），其中，凸起结构2000正对排屑口200a的侧面为垂直集尘槽200槽底的垂直面，而背向排屑口200a的侧面为倾斜面。当凸起结构2000为沿第二方向D2延伸的凸台时，毛刷2040的刷毛2040a沿着凸起结构2000的倾斜面将废屑和粉尘颗粒扫至下一区域；而毛刷2040背向排屑口200a方向移动过程中，当毛刷2040碰触到凸起结构2000的垂直面时，会被凸起结构2000迅速抬起，此时毛刷2040的刷毛2040a不再与槽底接触。而当毛刷2040越过凸起结构2000后，其刷毛2040a碰触槽底，而吸尘盒2022再次抵接毛刷2040，为下次一清扫作准备。
这里需要说明的是，每一吸尘组件202中吸尘盒2022的数量以及对应的清扫组件204中毛刷2040的数量可以为两个，也可以为四个甚至五个，这个可以依据集尘槽200的长度而定。
进一步地，上述排屑口200a呈漏斗状，排屑口200a的侧壁具有向下倾斜的倾斜面，以利于废屑和粉尘颗粒落入排屑口200a，并通过排屑口200a排出机床机身（图未示）外。
虽然上述清洁机构20可以用于清除飞溅至工作台10附近的废屑和粉尘颗粒，但该清洁机构20无法清洁工作台10上的废屑和粉尘颗粒，因此，实际使用时，可以将工作台10面残留的废屑和粉尘颗粒人工扫落至两侧的集尘槽200内，然后再通过吸尘组件202和清扫组件204清洁集尘槽200的废屑和粉尘颗粒。
相较于现有技术，本申请所述的自动清洁的机床通过在工作台两侧设置集尘槽收集飞溅至工作台附近的且废屑和粉尘颗粒，并通过在工作台两侧设置对应集尘槽的吸尘组件，利用工作台的往复运动，带动吸尘组件在集尘槽内来回移动，吸附飞溅至集尘槽内的废屑和粉尘颗粒，以避免废屑和粉尘颗粒在工作台附近逐渐堆积；此外，通过清扫组件与集尘槽内的凸起结构的相互配合，进一步将粘附在集尘槽槽底的粒径较大、质量较重的废屑和粉尘颗粒逐渐扫向集尘槽的排屑口，并通过排屑口排出机床之外，达到清洁的效果。本申请构思巧妙，结构简单，经济性好，实用性强。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，则本申请也意图包含这些改动和变形。
