The utility model discloses a simple tooling for locating the inner hole of a shaving cutter with a circular circle, including a three claw chuck, a three claw chuck including a disc body and a claw, and a number of three claw claw, and the three claw is uniformly arranged on the disc body in a circular ring. The inner surface of the three claw claw claw center is a circular concave surface, and a cylindrical mass rod is set on the arc concave surface. The volume bar is tangent to the arc concave surface. The axis of the quantity rod is parallel to the axis of the three claw chuck. The diameter of the rod is larger than the slot width of the razor, and when one side of the equivalent rod is placed between the two adjacent teeth of the razor, the opposite side of the rod is protruded out of the tooth top of the shaving cutter to make the arc concave between the claw and the razor noncontact. The concentricity of the inner hole and the circle of the shaving cutter can be ensured through the use of the simple tooling which is used to locate the inner hole of the sharpening cutter, and the combination of the three claw chuck and the measuring rod can ensure the precision of the inner hole of the sharpening and shaving cutter.

以节圆定位磨剃齿刀内孔的简易工装
本技术涉及磨剃齿刀内孔定位夹具,具体涉及一种以节圆定位磨剃齿刀内孔的简易工装。
技术介绍
磨内孔是剃齿刀加工中比较靠后的一道工序,在对剃齿刀进行梳齿后会进行磨内孔工序。在磨内孔时,需要对剃齿刀进行定位。图1所示为现有技术剃齿刀磨内孔工序时的定位装置示意图,其使用的是相对设置的两块压板1压住剃齿刀2的端面来进行定位。图1中,未画出剃齿刀的轮齿。由于径向剃齿刀梳齿小槽的深度和对称度是影响剃齿刀整体寿命的关键要素,而剃刀的内孔与分圆的同心度又是影响梳齿小槽质量的关键基准。然而由于磨内孔前面工序的机加工累计误差,再加上使用压板来定位难以保证同心度,因此造成剃齿刀磨内孔工序后和分圆同心度非常差。这样最后再经过刃磨齿形之后,就会出现剃齿刀的某几颗齿小槽非常浅而且左右面不对称,从而影响剃刀的整体寿命。
技术实现思路
有鉴于此,本技术的目的在于提供一种以节圆定位磨剃齿刀内孔的简易工装。为达到上述目的,本技术提供如下技术方案:一种以节圆定位磨剃齿刀内孔的简易工装,包括三爪卡盘,三爪卡盘包括盘体和卡爪,卡爪的数量为三个,该三个卡爪呈圆环形均匀布置在盘体上;卡爪的面向三爪卡盘圆心的内侧面为圆弧凹面,在圆弧凹面上设有圆柱形的量棒,量棒与圆弧凹面相切,量棒的轴线与三爪卡盘的轴线平行;量棒的直径大于剃齿刀的齿槽宽,并且当量棒的一侧面放置在剃齿刀的相邻两个轮齿之间时,量棒的相对另一侧面向外凸出超过剃齿刀的轮齿齿顶以使卡爪的圆弧凹面与剃齿刀之间非接触。进一步的,量棒与圆弧凹面之间为可拆式连接。进一步的,量棒固定安装在圆弧凹面上。本技术的有益效果在于:通过采用 ...
