Description

轴承密封盖压装模具
技术领域
本实用新型涉及轴承加工技术领域,尤其涉及轴承密封盖压装模具。
背景技术
轴承是最常见的一种机械零部件,轴承起到支撑旋转轴的作用,应用于各种机械传动结构。
如图1所示的,轴承包括外圈1、内圈2、滚珠3、保持架4等,为了 防止外部灰尘、杂物及液体进入轴承内部,通常在轴承的外侧位于外圈1 和内圈2之间设有防尘圈5(也可以称之为轴承密封盖)。如图2所示的,防尘圈5呈环状,防尘圈5 包括卷边51、折弯部52及水平部53。如图1所示的,为了便于将防尘圈 5安装在内圈2与外圈1之间,通常在外圈1的内侧开设有凹槽,防尘圈5 的卷边51可卡于所述凹槽内。在将防尘圈压入内圈和外圈之间的密封槽时由于防尘圈的不规则结构导致压入位置不精确,防尘圈可能安装不到位,失去应用的保护功能。
中国实用新型专利公开号CN203702896U公开了一种带内圈倒角检测的压盖模,其中具体公开了两种压盖模,一种是导向柱 与基台的连接角为直角的压盖模,另一种是导向柱与基座的连接处设有过渡斜面,所述过渡斜面的角度与待压合的轴承内 圈倒角相同的压盖模,但无论是哪种压盖模,由于缺乏和防尘圈的折弯部相适配的部分,导致防尘圈压入时定位不准确,会产生径向和轴向位置偏差,导致防尘圈无法实现应有的密封功能。
实用新型内容
本实用新型要解决的技术问题是现有的轴承密封盖压装模具压装轴承密封盖时无法准确定位,产生位置偏差,为此提供一种轴承密封盖压装模具。
本实用新型的技术方案是:轴承密封盖压装模具,它包括压盖模芯部、压模套筒和压模内定位块,所述压盖模芯部包括基座,所述基座顶部固接有导向部,所述基座底部边缘向下延伸有锥台,所述压盖套筒套接于基座外,所述压模内定位块与基座底部固接并保持同心,所述压模内定位块包括定位芯和位于定位芯外的环形外缘部,所述环形外缘部贴靠在锥台内侧并与锥台的锥面形成折弯部,所述压盖套筒的端面与锥台的锥面保留一定距离。
上述方案中所述锥台的外锥面锥角小于内锥面锥角。
上述方案中所述锥台的外锥面锥角为30°,内锥面锥角为45°。
上述方案的改进是所述基座与导向部过渡的区域具有呈直径的扩张的肩部,所述肩部与压盖套筒的端面贴合。
上述方案中所述定位芯通过螺栓与基座同心固接。
上述方案中所述压模套筒侧壁通过螺钉与基座固定。
本实用新型的有益效果是压模套筒、锥台和环形外缘部配合,在压入轴承密封盖时与轴承密封盖的折弯部贴合将轴承密封盖准确的压入密封槽内,避免产生轴向和径向位置偏差;整体结构简单,易于拆卸维护,延长使用寿命。

具体实施方式
如图3所示,本实用新型包括压盖模芯部、压模套筒和压模内定位块,所述压盖模芯部包括基座6,所述基座顶部固接有导向部7,所述基座底部边缘向下延伸有锥台8,所述压盖套筒套接于基座外,所述压模内定位块与基座底部固接并保持同心,所述压模内定位块包括定位芯9和位于定位芯外的环形外缘部10,所述环形外缘部贴靠在锥台内侧并与锥台的锥面形成折弯部11,所述压盖套筒的端面与锥台的锥面保留一定距离。
下面结合附图及实施例对本实用新型做进一步说明。
本实用新型中提到的“内”和“外”指的是相对于装配好的轴承密封盖压装模具而言,例如内锥面指的是与压模内定位块配合的面,外锥面指的是与靠近压模套筒的面。
实施例1:轴承密封盖压装模具,它包括压盖模芯部、压模套筒和压模内定位块,所述压盖模芯部包括基座6,所述基座顶部固接有导向部7,该导向部与注脂压盖机的气缸连接,本实用新型被气缸带动上下移动。所述基座底部边缘向下延伸有锥台8,该锥台具有外锥面和内锥面,外锥面的锥角为30°,内锥面的锥角为45°,内锥面的高度为0.25mm,所述压盖套筒套接于基座外,所述压模内定位块与基座底部固接并保持同心,所述压模内定位块包括定位芯9和位于定位芯外的环形外缘部10,定位芯和环形外缘部同心,所述环形外缘部贴靠在锥台内侧并与锥台的锥面形成折弯部11,该锥面指的当然是内锥面,该折弯部与轴承密封盖的折弯部完全贴合,所述压盖套筒的端面与锥台的锥面保留一定距离,该距离根据轴承具体型号确定尺寸。
实施例2:与实施例1的区别在于外锥面的锥角为20°,内锥面的锥角为45°,内锥面的高度为0.3mm。
实施例3:与实施例1的区别在于所述基座与导向部过渡的区域具有呈直径的扩张的肩部12,所述肩部与压盖套筒的端面贴合。该肩部可以起到给压盖套筒轴向定位的作用,防止压装轴承密封盖时压盖套筒上移。
实施例4:与实施例1的区别在于压盖套筒的侧壁开设有供螺钉旋入的通孔,通过旋入的螺钉将压盖套筒与基座牢固的固定在一起,保证整体结构的稳定性。
上述实施例1-3可以任意组合使用,只要本领域技术人员不会由此得到明显不可能的技术方案都属于本实用新型的保护范围内。
本实用新型中的定位芯可以通过螺栓与基座同心固接,当然也可以是焊接、铆接等等其他固定连接方式,但是螺栓连接便于拆卸维护。定位芯可以是如图3所示的圆台,其中心开设有圆形凹槽,该圆形凹槽的内径比轴承内孔小0.05~0.06mm,保证轴承径向定位的准确性,环形外缘部的內缘直径比密封盖内径大2mm左右。
本实用新型的使用方法如下:将导向部与注脂压盖机的气缸连接,调整气缸压力为0.25~0.3MPa,气缸推动压盖模具向下移动,内锥面与环形外缘部配合形成的折弯部与轴承密封盖的折弯部对应贴合,保证轴承密封盖均匀受力,内锥面将轴承密封盖平稳的压入密封槽内。由于内锥面长期使用会出现磨损现象,可以通过拆下模具,磨压盖套筒端面以及内外锥面来保证装配后各零件的位置关系,从而保证压入的位置。
