对于小批量多规格的冲孔件,采用固定式定位装置是不经济的。笔者根据平面坐标的原理,设计了坐标式可调冲孔模定位装置。该装置底板材料HT20-40,大小与冲床台面相同,在x和y轴上开T型槽。十字块材料45号钢,HRC40～45,b_2端嵌入T型槽,B_2端和定位条的B_1槽相配。十字块与T型槽和定位条的配合为H7/f7。在T型槽旁铣槽按标尺(也可用普通钢皮尺代替)。根据不同的冲件外形移动定位条在x和y轴的位置上,用螺栓紧固即可。经生产实践证明:该装置定位灵活方便、直观精确、通用性强,适用
For small quantities of multi-standard punching parts, the use of fixed positioning device is not economical. According to the principle of plane coordinate, the author designed a coordinate adjustable punching mode positioning device. The device floor material HT20-40, the same size and punch table, open in the x and y-axis T-slot. Cross block material 45 steel, HRC40 ~ 45, b_2 end embedded in the T-slot, B_2 end and the positioning of the B_1 slot match. Cross with the T-slot and positioning bar with the H7 / f7. Grooving grooves in the T-groove by the rod (also available ordinary steel tape instead of). Depending on the shape of the punch moves the positioning bar in the x and y-axis position, the bolt can be fastened. The production proved that: The device positioning flexible and convenient, intuitive and accurate, versatile, applicable
