Description

瓷砖磨平抛光用磨块的自摆驱动方法及自摆驱动装置
技术领域
本发明涉及一种瓷砖加工机械，特别涉及一种瓷砖抛光磨平用磨块的自摆驱动方法及自摆驱动装置。
背景技术
在陶瓷瓷砖产品生产加工的过程中，需要将压制好的土坯烧制成砖坯，烧制好的砖坯还要经过抛光磨平（一次抛光）、抛光打蜡（或者是防污抛光，又称为二次抛光）等工序才能形成成品，因此，将烧制好的砖坯抛光磨平是一道很重要的工序，处理好了才能使抛光打蜡等后续处理达到相应的效果。目前这道工序主要是由抛光生产线来完成，在抛光生产线中设置有多行多列的磨块对流水线上经过的瓷砖砖坯进行抛光磨平。一组磨块在进行公转抛光磨平的同时每个磨块还会各自进行钟摆式的自摆。
现有磨块的运动基本上是这样实现的：磨头外壳通过连接于其上的一组磨块座对应安装一组磨块（一组有六个或十个不等），磨头外壳在磨头主轴的带动下进行旋转，从而带动磨块座上的磨块进行公转。磨头主轴的公转，是通过与磨头驱动装置主轴连接，由磨头驱动装置主轴带动的。在磨头外壳内设置有齿轮组，该齿轮组包括相互啮合作用的主动齿轮和从动齿轮组。主动齿轮套设在与磨头外壳内底部固定连接的磨头空心轴一上（因此主动齿轮的转速与磨头外壳相同），经过相互啮合的从动齿轮组的传动使主动齿轮与从动齿轮组之间形成转速差，从动齿轮组最后带动磨头空心轴二，这样磨头外壳与磨头空心轴二之间就产生转速差，这个转速差使得同时分别连接磨头外壳和磨头空心轴二的磨块自摆连动装置（例如凸轮机构）工作，带动磨块进行钟摆式的自摆。
与瓷砖二次抛光程序不同的是，在这种自摆方式中，磨块公转要求转速非常快（即主动齿轮需要高速转动），而磨块自摆运动来说，只需要相对很低的转速，这就使得安装在磨头外壳中的主动齿轮和从动齿轮组的结构非常复杂，才能将公转的高速调至磨块自摆需要的低速，且其中大部分的齿轮也必须长期运行在高速转动的状态，这样就导致齿轮组的机械损耗大大提高，使用寿命大大降低，一般4-6个月就需要停机更换齿轮。齿轮组设置在磨头外壳中，拆卸时必须将整个磨头外壳先拆下来才能更换，不仅拆卸工作量大，维修成本高，拆卸安装时间长也造成极大经济损失。
采用主动齿轮和从动齿轮组进行降速带来的另外一个不足之处在于：对磨块自摆速率的调节会因为齿轮齿数比的限制，不能实现任意速率的调节，即无法适应不同硬度砖坯的抛光磨平要求。
发明内容
本发明的目的在于提供一种瓷砖抛光磨平用磨块的自摆驱动方法。通过该种自摆驱动方法，磨头空心轴二的转速调节放置在磨头外壳外部进行，彻底改变了磨头空心轴二的驱动装置放置在磨头外壳中的传统模式，方便维修和更换；还可以使磨头空心轴二的转速彻底脱离了与磨头主轴高速公转的关联，使其磨损率大大降低，在瓷砖加工机械的使用寿命内都无需更换，具有巨大的优势。本发明的另一目的在于提供实现上述自摆驱动方法的磨块自摆驱动装置。
为达上述目的，本发明采用如下的技术方案：一种瓷砖抛光磨平用磨块的自摆驱动方法，磨块通过磨块座与磨头外壳连接，磨块自摆连动装置连接磨块座；其特征是，磨块自摆的驱动由连接在磨块自摆连动装置两端的机构之间的转速差形成，其中一端的机构的转速与磨块公转的转速相同，另一端的机构的转速由设置在磨头外壳外部的自摆驱动装置调节。
通过如上方法，由于磨头主轴的转速已定，只要在磨头外壳外部的自摆驱动装置调节设置好另一端的机构的转速即可。这样在调节和维修自摆驱动装置就无需进行磨头外壳的整体拆装，工作量极大减少。更重要的是，通过如上方法，另一端的机构的转速就可以彻底摆脱高速转动的磨头主轴，降低了机械的磨损，延长了使用寿命，同时减轻了磨头外壳整体的重量，降低了能耗。
更具体地说，所述另一端的机构的转速由设置在磨头外壳外部的自摆驱动装置调节是指，在确定了磨块自摆的频率即确定了磨块自摆连动装置两端的机构之间的转速差之后，按确定的转速差设定另一端的机构的转速，然后自摆驱动装置按照设定的转速带动另一端的机构转动。
所述自摆驱动装置按照设定的转速带动另一端的机构转动是指，自摆驱动装置驱动传动装置后再由传动装置按照设定的转速带动另一端的机构转动。
按照如上方法，就可以很方便地实现磨块自摆频率的调节，而不必对磨头外壳整体进行拆装调节。
一种瓷砖抛光磨平用磨块的自摆驱动装置，磨块通过磨块座与磨头外壳连接，磨块自摆连动装置连接磨块座；其特征是，自摆驱动装置包括具有转速差的自摆驱动装置一和自摆驱动装置二，磨块自摆连动装置的两端分别连接自摆驱动装置一和自摆驱动装置二；其中，自摆驱动装置一与磨头主轴连接，自摆驱动装置二伸出磨头外壳外连接外设驱动装置。
根据如上技术方案，自摆驱动装置二的驱动外设，只要在磨头外壳外部的外设驱动装置设置好自摆驱动装置二的转速即可。这样在调节和维修时就无需进行磨头外壳的整体拆装，工作量极大减少。更重要的是，通过根据如上方案，自摆驱动装置二的转速就可以彻底摆脱高速转动的磨头主轴，降低了机械磨损，延长了使用寿命，同时减轻了磨头外壳整体的重量，降低了能耗。
更具体地说，所述自摆驱动装置二是指套设在磨头主轴外且以磨头主轴为轴心的磨头空心轴二；外设驱动装置用于驱动磨头空心轴二转动。
由于自摆驱动装置二为设置在磨头外壳内的空心轴，其驱动外设，空心轴使用寿命长，损耗低，因此在整个抛光生产线的使用过程中基本不需要维修和更换，也即磨头外壳不需要反复拆装，大大减低了整个生产线的维护难度和工作量。
所述外设驱动装置用于驱动磨头空心轴二转动是指，外设驱动装置直接驱动磨头空心轴二。
所述外设驱动装置用于驱动磨头空心轴二转动是指，还设置有连接套，在连接套内，磨头主轴与磨头驱动装置主轴通过连接件上下连接，连接套与磨头空心轴二以磨头主轴或磨头驱动装置主轴为轴心同轴上下连接，外设驱动装置先驱动连接套，再由连接套带动磨头空心轴二。
在现有的瓷砖生产机械中，磨头主轴与磨头驱动装置主轴在连接套内进行连接，连接套的作用之一是可以对两者的连接处进行防护保护，作用之二是对磨头主轴的横向运动进行限制，使磨头主轴只具有上下移动的空间，保证磨头转动的平稳不左右摆动，因此在现有的瓷砖生产机械中，连接套是一种固定套，固定在瓷砖生产机械的大梁上。而在本技术方案中，连接套仍然具有防护保护作用，也仍然对磨头主轴的横向运动进行限制，而区别在于其不再是固定套，而是成为了自摆驱动装置二的一个传动件，通过连接套与自摆驱动装置二的连接巧妙地实现了连接套的固定，为连接套赋予了新的作用和功能，充分利用了瓷砖生产机械的原有装置，设计巧妙，降低了改造成本。
作为具体的一个实施方案：所述外设驱动装置先驱动连接套是指，在磨头驱动装置主轴外与连接套之间还套装有磨头驱动装置空心轴二，磨头驱动装置空心轴二与连接套以磨头驱动装置主轴为轴心同轴固定连接，外设驱动装置输出连接磨头驱动装置空心轴二，由磨头驱动装置空心轴二带动连接套转动。
磨头驱动装置空心轴二通过轴承套接在磨头驱动装置主轴外和固定架之间，其底部与连接套横向固定连接，这样连接套就同时与磨头驱动装置空心轴二和磨头空心轴二连接，而磨头驱动装置空心轴二有固定架固定支撑，就可以保证连接套在转动时的平稳性。同时，磨头驱动装置空心轴二也对磨头驱动装置主轴的横向运动进行限制，进一步提高了磨头驱动装置主轴与磨头主轴转动的平稳性。这是优选方案。
所述自摆驱动装置一是指磨头外壳，磨头主轴连接在磨头外壳的内底部；所述外设驱动装置是指如下方式之一：（一）独立设置的电机及其带动的传动装置；（二）磨头驱动装置主轴驱动电机及其带动的两组速度不同的传动装置，其中一组传动用于带动自摆驱动装置二，另一组传动用于带动磨头驱动装置主轴。以上两种外设驱动装置的设置模式可以任选其一，如果采用的是磨头驱动装置主轴驱动电机，能更充分地利用原有设备。
具体地说，第一种方式中所述的独立设置的电机及其带动的传动装置是指，单独设立一个电机用于驱动自摆驱动装置二，传动装置为皮带轮或齿轮组；第二种方式中所述的磨头驱动装置主轴驱动电机及其带动的两组速度不同的传动装置，其中一组传动用于带动自摆驱动装置二是指，传动装置为皮带轮或齿轮组，磨头驱动装置主轴驱动电机的输出连接两组皮带轮或两个齿轮组，其中一组皮带轮或齿轮组带动自摆驱动装置二，另一组皮带轮或齿轮组驱动磨头驱动装置主轴，两组速度不同。这样就最终实现了磨头外壳与磨头空心轴二具有转速差。
所述磨头驱动装置主轴的上方还设置有升降气缸。用于磨头驱动装置主轴的上升和下降。
本发明相对于现有技术具有的主要优点及效果是：
1、本发明公开的瓷砖抛光磨平用磨块的自摆驱动方法及自摆驱动装置，将自摆驱动装置二的转速由设置在磨头外壳外部的外设驱动装置调节，完全突破了传统的驱动方式，这样在调节和维修时就无需进行磨头外壳的整体拆装，工作量极大减少；而且自摆驱动装置二的转速彻底摆脱了与高速转动的磨头主轴的关联，只需保持低速转动，降低了机械磨损，延长了使用寿命，同时减轻了磨头外壳整体的重量，降低了能耗。
2、本发明公开的瓷砖抛光磨平用磨块的自摆驱动方法及自摆驱动装置充分利用了现有设备中的配件，成本低，可行性高。

具体实施方式
下面结合实施例及附图对本发明作进一步详细的描述，但本发明的实施方式不限于此。
实施例一
本发明公开了一种瓷砖抛光磨平用磨块的自摆驱动方法：自摆的驱动由自摆驱动装置一与自摆驱动装置二的转速差形成、由与自摆驱动装置一与自摆驱动装置二分别连接的磨块自摆连动装置实现；自摆驱动装置一的转速与磨头主轴的转速相同，自摆驱动装置二的转速由设置在磨头外壳外部的外设驱动装置调节，即：在确定了磨块自摆的频率即自摆驱动装置一自摆驱动装置二的转速差之后，按确定的转速差设定自摆驱动装置二的转速，然后由外设驱动装置按照设定的转速带动自摆驱动装置二转动，或者由外设驱动装置驱动传动装置后再由传动装置按照设定的转速带动自摆驱动装置二转动。
如图1所示，本发明还公开了与上述方法对应的一种瓷砖抛光磨平用磨块的自摆驱动装置，连接磨块自摆连动装置4（磨块自摆连动装置可采用凸轮装置）；自摆驱动装置由具有转速差的磨头外壳3与磨头空心轴二2（作为自摆驱动装置二）组成，磨头空心轴一1与磨头空心轴二2以磨头主轴5为轴心内外套装，磨块自摆连动装置4分别连接磨头外壳3和磨头空心轴二2；磨头空心轴一1和磨头主轴5均与磨头外壳3固定连接（因此磨头空心轴一1、磨头主轴5和磨头外壳3具有相同的角转速），而磨头空心轴二2伸出磨头外壳3；在连接套6内，磨头主轴5与磨头驱动装置主轴7通过连接件上下连接；连接套6与磨头空心轴二2在磨头外壳3外以磨头主轴5或磨头驱动装置主轴7为轴心同轴通过连接件18上下连接。在磨头驱动装置主轴7外与连接套6之间还套装有磨头驱动装置空心轴二9，在实际使用中，磨头驱动装置主轴7外先套装有磨头驱动装置空心轴一8，在磨头驱动装置空心轴一8与磨头驱动装置空心轴二9之间设置轴承20，磨头驱动装置空心轴二9还通过轴承19与固定架10连接，以保证平稳性。磨头驱动装置空心轴二9与连接套6以磨头驱动装置主轴7为轴心同轴固定连接。电机11是采用磨头驱动装置主轴驱动电机，磨头驱动装置主轴驱动电机11输出先带动皮带轮121、122，皮带轮122带动皮带15，皮带15带动皮带轮131、132，皮带轮121和122通过皮带14连接，皮带轮131好132通过皮带16连接，两组皮带轮的转速不同（两组皮带轮作为转速不同的传动装置）。皮带轮131和132带动磨头驱动装置空心轴二9转动，最终带动磨头空心轴二2转动，磨头主轴5与磨头外壳3内底部固定连接，磨头主轴5由皮带轮121和122带动，因此，磨头外壳3与磨头空心轴二2具有转速差，两者驱动磨块连动装置4，最终使磨块进行自摆。磨头驱动装置主轴7的上方还连接有升降气缸17，用于磨头驱动装置主轴7的升降。
在本实施方案中，磨块自摆驱动装置是这样工作的：电机11转动带动皮带轮121、122，再带动皮带轮131、132，皮带轮121、122带动磨头驱动装置主轴7转动（磨头驱动装置主轴7由设置在其外的磨头驱动装置空心轴一8带动）、皮带轮131、132带动磨头驱动装置空心轴二9转动。磨头驱动装置主轴7带动磨头主轴5和磨头空心轴一1及磨头外壳3转动，此时磨头外壳3具有与磨头主轴5相同的角转速。磨头驱动装置空心轴二9转动带动连接套6和磨头空心轴二2转动，此时磨头空心轴二2具有与磨头驱动装置空心轴二9相同的角转速，由于两组皮带轮的转速不同，则磨头外壳3与磨头空心轴二2存在转速差，这个转速差就带动磨块自摆连动装置4激发与磨头外壳连接的磨块座22做钟摆式自摆运动。
当需要调节钟摆式自摆运动的频率时，只需要调节两组皮带轮之间的转速差即可，非常方便。而且皮带轮的转速调节，不会受到齿轮齿数比例的影响，可以实现任意比例的调节，是优选方案。在此例中，两组皮带轮也可以用两组齿轮组来代替。
实施例二
本实施例与实施例一不同之处仅在于，外设驱动装置的电机为独立设置的电机（图1中未示出），其直接驱动皮带轮131和132，磨块驱动装置主轴由其专用电机11驱动，电机11只驱动磨头驱动装置空心轴一8，其它结构均与实施例一相同。
实施例三
本实施例与实施例二不同之处仅在于，独立设置的电机的一组皮带轮131、132直接驱动连接套6，而磨头驱动装置空心轴一8通过轴承20与固定架10相连，不需要磨头驱动装置空心轴二9，其它结构与实施例二相同。
实施例四
本实施例与实施例三不同之处仅在于，电机为磨块驱动装置主轴驱动电机11，电机11带动皮带轮131和132直接驱动连接套6，其它结构均与实施例三相同。
上述实施例为本发明较佳的实施方式，但本发明的实施方式并不受上述实施例的限制，其他的任何未背离本发明的精神实质与原理下所作的改变、修饰、替代、组合、简化，均应为等效的置换方式，都包含在本发明的保护范围之内。
