Description
技术领域technical field
本发明是一种薄板试件钻孔快速装夹装置。The invention relates to a fast clamping device for drilling a thin plate test piece.
背景技术Background technique
随着航天材料越来越趋于轻型化方向发展，轻合金、复合材料等在航天制造领域内被广泛应用。铝合金薄壁型整体结构件以其强度高，质量轻等优点被大量应用。目前铝合金薄壁件的装配方法一般是采用紧固连接的方式，以铆接和螺纹连接为主, 这两种连接方式都需要事先钻孔。由于这类零件尺寸较大，使得钻孔数量极多。同时这类孔精度要求也较高，导致钻孔过程中存在孔口毛刺、刀具磨损及效率低下等问题。为了分析这类零件的钻孔过程，通常进行大量的薄板试件钻孔实验。研究发现在薄板试件钻孔实验中，试件的装夹方式和装夹精度对实验过程有非常大的影响。传统的装夹方式是利用机床虎钳进行夹持，采用千分表进行找正和调平。不仅效率低下，而且在横向加紧力的作用下薄板试件会产生弯曲变形，试件平面无法保证水平，容易引起刀具振动，黏屑等问题，严重影响钻孔质量和刀具寿命。此外测温、喷淋和摄像实验装置的安装不便。因此研制低成本、高效的薄板试件钻孔快速装夹装置就成为钻孔机理实验研究的一个迫切需求。As aerospace materials tend to be more and more lightweight, light alloys and composite materials are widely used in the field of aerospace manufacturing. Aluminum alloy thin-walled integral structural parts are widely used due to their high strength and light weight. At present, the assembly method of aluminum alloy thin-walled parts generally adopts fastening connection, mainly riveting and screw connection, both of which require pre-drilling. Due to the large size of these parts, the number of drilled holes is extremely high. At the same time, the precision requirements of this type of hole are also high, resulting in problems such as hole burrs, tool wear and low efficiency during the drilling process. In order to analyze the drilling process of such parts, a large number of thin plate specimen drilling experiments are usually carried out. The study found that in the drilling experiment of thin plate specimens, the clamping method and clamping accuracy of the specimen have a great influence on the experimental process. The traditional clamping method is to use a machine tool vise for clamping, and a dial indicator for alignment and leveling. Not only is the efficiency low, but also the thin-plate test piece will be bent and deformed under the action of the lateral clamping force, and the plane of the test piece cannot be guaranteed to be horizontal, which is likely to cause problems such as tool vibration and chip sticking, which seriously affect the drilling quality and tool life. In addition, it is inconvenient to install the temperature measuring, spraying and camera experiment devices. Therefore, it is an urgent need to develop a low-cost, high-efficiency fast clamping device for drilling holes in thin plate specimens.
