Description

一种推瓦机构
技术领域
本实用新型涉及磁体磨加工生产技术领域,特别是涉及一种用于对瓦型磁体进行磨削加工的推瓦机构。
背景技术
目前瓦形磁体在机电行业被国内外广泛使用,随着电磁工业产品要求不断提高,同时要求瓦形磁体的精度和外形尺寸也越来越高。
瓦形磁体在从熟坯到合格的成品生产过程中,需要经过多道磨削工序进行加工,在加工前,为了满足自动化要求及加工工艺的要求,通常需要采用推瓦机构将磁瓦送入加工区域进行磨削,而由于现有磁瓦的输送方式多是依靠一个磁瓦抵靠一个磁瓦实现逐步传送的,因此相邻磁瓦之间都是硬性接触,现有的推瓦机构都是通过气缸直接将磁瓦逐个推入,因其冲击力过大,容易造成磁瓦之间因相互抵靠挤压、碰撞而破损,从而大大影响磁瓦的产品质量,甚至造成磁瓦直接报废。
实用新型内容
本实用新型的发明目的在于,针对上述存在的技术问题,提供一种能够大大降低磁瓦在推入时因相互挤压碰撞而造成破损的推瓦机构。
本实用新型的技术方案是这样实现的:一种推瓦机构,其特征在于:包括推瓦气缸、推瓦杆、直线导轨以及摇杆,所述推瓦杆与推瓦气缸的活塞杆连接,所述推瓦气缸为常通气状态,所述推瓦杆可滑动地设置在直线导轨上,所述摇杆上端与推瓦杆后端部铰接,其下端与推瓦杆复位驱动机构连接,所述摇杆中部铰接在安装座上;在进瓦时,所述推瓦杆复位驱动机构取消对摇杆下端的作用力,所述推瓦杆在推瓦气缸的作用下沿直线导轨运动,将磁瓦推入至磨削区域,在磁瓦被推入后,所述推瓦杆复位驱动机构对摇杆下端作用,使推瓦杆克服推瓦气缸的作用力回到推瓦的起始点位置,准备进行下一次的推瓦动作。
本实用新型所述的推瓦机构,其所述推瓦杆复位驱动机构包括推瓦回程凸轮和凸轮转轴,所述摇杆下端与推瓦回程凸轮对应抵靠,所述推瓦回程凸轮通过凸轮转轴与安装座转动连接,所述凸轮转轴与驱动机构连接,在进瓦时,所述推瓦回程凸轮的高点逐渐远离摇杆的下端部,所述推瓦杆在推瓦气缸的作用下沿直线导轨运动,将磁瓦推入至磨削区域,随着凸轮转轴的转动,推瓦回程凸轮的高点再逐渐接近摇杆的下端部,使推瓦杆克服推瓦气缸的作用力回到推瓦的起始点位置。
本实用新型所述的推瓦机构,其在所述凸轮转轴上设置有旋转编码器。
本实用新型通过推瓦气缸与推瓦杆复位驱动机构的配合,在推瓦与复位的过程中,推瓦气缸始终处于充气状态,对推瓦杆形成稳定持续的作用力,同时利用推瓦杆复位驱动机构作用力的变化,来实现磁瓦的推进及推瓦杆的复位动作,这样大大降低了磁瓦在推入时因相互挤压碰撞而造成破损。
