The invention relates to a mechanical zero setting device and method for a linear steering engine. The mechanical zero setting device comprises a zero tool, a conical positioning pin, a pin shaft, a T-shaped positioning pin and a locking nut. The zero-position tool is composed of a first U-shaped block and a second U-shaped block which are perpendicular to each other, the first U-shaped block is parallel to the stroke direction of the steering engine lead screw, and the second U-shaped block is perpendicularly fixed to the first U-shaped block; oval sliding grooves are formed in the left side wall and the right side wall of the second U-shaped block, a check block is arranged on the outer wall below the oval sliding grooves, and a plurality of zero position holes are formed in the upper end face of the check block; a U-shaped opening of the first U-shaped block is connected with two base holes in the front end of the steering engine and is locked through two conical positioning pins, a pin shaft penetrates through a front supporting lug hole of a lead screw of the steering engine and an oval sliding groove of the second U-shaped block, and a locking nut is screwed on the pin shaft. The T-shaped positioning pin is inserted into a positioning hole formed in the side face of the head of the pin shaft and can fall into one zero position hole along with sliding of the pin shaft during mechanical zero adjustment. According to the invention, precise stepless adjustment of the mechanical zero position can be realized quickly, simply and conveniently.

    本发明涉及一种直线舵机机械调零装置及方法,包括零位工装、锥形定位销、销轴、T型定位销和锁紧螺母;零位工装由两个相互垂直安装的第一U形块、第二U形块组成,第一U形块与舵机丝杠行程方向平行,第二U形块垂直固定在第一U形块上;第二U形块左右两侧壁开设椭圆滑槽,在椭圆滑槽下方的外壁设有挡块,挡块上端面设有若干个零位孔;第一U形块的U形开口与舵机前端的两个底座孔连接,通过两个锥形定位销锁紧,销轴穿过舵机丝杠的前支耳孔和第二U形块的椭圆滑槽,锁紧螺母旋到销轴上;T型定位销插入到销轴头部侧面开设的定位孔中,在进行机械调零时会随销轴的滑动落入其中一个零位孔中。本发明可以快速简便实现机械零位的精准无级调节。
