一种实现开槽中心导体精密定心收口的夹具及收口方法 Precise centering of one kind of conductor clamps shut and grooved central shut-implemented method

技术领域 FIELD

[0001] 本发明属于微波同轴传输线制作技术领域,尤其涉及的是一种实现开槽中心导体精密定心收口的夹具及收口方法。 [0001] The present invention belongs to the technical field of microwave coaxial transmission line, and more particularly, to a clamp shut grooving method for achieving precise centering of the center conductor is shut.

背景技术 Background technique

[0002] 微波信号传输通路的中心导体一般分为阳头中心导体和阴头中心导体(即开槽中心导体),随着技术的不断发展,测试信号频率不断提高,要求连接器中的中心导体尺寸越来越小,精度要求也越来越高,而开槽中心导体的收口与定型工艺是生产符合设计要求的高性能开槽中心导体的关键工艺技术,收口导体的收口精度、同轴度和真圆度直接影响到广品的核心性能指标。 [0002] The center conductor of the microwave signal transmission path is generally divided into the male and female center conductor center conductor (i.e. slotted center conductor), along with the development of technology, the test signal increasing frequency requirements of the central conductor connector smaller size, higher and higher precision, and shut the setting process is to produce a center conductor slotted key technology meet high performance requirements of the slotted design of the center conductor, the conductor shut shut accuracy, concentricity and the roundness of a direct impact on core performance indicators wide product.

[0003] 现有开槽阴头中心导体的收口工艺,大多采用的是手工收口的方式,即操作人员用镊子、钢丝等工具直接作用于开槽中心导体使其变形达到收口,然后将零件置于热处理设备中进行时效强化定型。 [0003] Existing processes shut head slotted female center conductor, is mostly used in the manual shut manner, i.e. the tool operator acts directly with forceps, deformed steel wire reaches the central conductor in the slot shut, then the part opposite strengthen stereotypes in aging heat treatment equipment.

[0004] 除手工收口方式外,近年来也出现了利用模具进行开槽中心导体收口定型的技术方案,模具的截面形状为锥形孔,收口时直接将开槽中心导体直接压入锥形孔,利用锥形孔的内表面对开槽中心导体的收口后外形进行定位定形,之后进行时效热处理。 [0004] In addition to the manual shut way, in recent years there have been grooved using a mold for shaping the central conductor shut aspect, the sectional shape of the die aperture is tapered, slotted directly shut when the center conductor is pressed into the tapered bore directly , by the tapered inner surface of the bore of the slotted central conductor cuffs positioned amorphous shape, followed by aging heat treatment.

[0005] 手工收口方法存在的主要问题是:中心导体尺寸较小,手工操作麻烦,生产效率低;易导致孔瓣变形,产品良品率低;收口精度差,收口后截面真圆度和同轴度难以保证;产品质量受人的不稳定因素影响难以有良好的一致性,导致性能指标及稳定性差。 [0005] The main problem is the manual shut: the smaller the size of the center conductor, troublesome manual operation, production efficiency is low; easily cause deformation of the valve hole, the product yield is low; shut accuracy, roundness and cross section of the coaxial shut degree is difficult to guarantee; affect product quality by the people of instability is difficult to have good consistency, resulting in poor performance and stability.

[0006] 现有的利用模具进行开槽中心导体收口定型的技术方案中,将开槽中心导体直接压入锥形孔时必须确保插孔四个孔瓣恰好接触,形成一个封闭的圆环形。 [0006] using the conventional mold must ensure that the receptacle just touches the four valve holes when the center conductor slotted shut stereotypes aspect, the center conductor slotted directly into the taper hole formed in a closed annular . 但现有方案中并未有任何措施来保证这一效果,同样靠操作人员的经验来保证,实际生产中常出现因压入过紧造成部分孔瓣向内变形过度,造成开槽导体报废;或导体压入不垂直造成收口偏心,直接影响连接器同轴度和真圆度指标;或开槽导体压入量不足造成欠收口,进而导致插拔力和插拔寿命不能满足设计要求。 However, existing solutions are not any measures to ensure this effect, by the same experienced operator to ensure that the actual production often occurs due to press-fitting hole tight flap portion inwardly causing excessive deformation, resulting in scrapped slotted conductor; or does not cause vertical conductor pressed shut eccentric connector directly affects the concentricity and roundness index; or pressed into the slotted conductor opening failures caused by insufficient amount, leading to plug the power plug life and can not meet the design requirements.

[0007] 因此,现有技术存在缺陷,需要改进。 [0007] Thus, deficiencies of the prior art, needs to be improved.
