Description

Multipurpose front-back guiding test knife device Technical Field The utility model belongs to the technical field of aircraft assembly manufacturing process equipment, and particularly relates to a multipurpose front-rear guiding test knife device. Background At present, a front guide cutter, a rear guide cutter and front and rear guide cutters are commonly used in aircraft assembly and manufacture, and corresponding different test tool holders are arranged for different types of cutters with different sizes, so that on one hand, the test tool holders cannot be commonly used, the new custom test tool holders are long in period and high in cost and occupy factory building arrangement, and on the other hand, the test tool holders are required to be synchronously changed once the cutters are changed, and the period is long. Disclosure of utility model The utility model aims to solve the problem that the tool holders required by the tool holders for the tools of different sizes and different guide types clamped by tools such as an air drill, an electric drill, an automatic feeding drill and the like in the conventional aircraft assembly cannot be unified before product processing, thereby providing a multipurpose front-rear guide tool holder which can be universally used for the tool holders of different sizes and different guide types clamped by the tools such as the air drill, the electric drill, the automatic feeding drill and the like, avoids the problems of long customization period of the tool holders, occupies the use area of a factory, and improves the universality of the tool holders. In order to achieve the aim, the multipurpose front-rear guide test knife device comprises a stop block, a bottom plate, a rear guide fixing assembly, a precise guide rail, a test knife bushing fixing assembly and a front guide fixing assembly, wherein the two precise guide rails are fixed on the bottom plate in parallel, the rear guide fixing assembly, the test knife bushing fixing assembly and the two ends of the bottom of the front guide fixing assembly are respectively arranged on the two precise guide rails and are sequentially arranged at the rear, middle and front parallel positions, the rear guide fixing assembly, the test knife bushing fixing assembly and the front guide fixing assembly can slide on the precise guide rails, the end parts of the two precise guide rails are detachably connected with the stop block, the rear guide bushing is arranged on the rear guide fixing assembly, the test knife bushing is arranged on the test knife bushing fixing assembly, and the front guide bushing is arranged on the front guide fixing assembly. Further, the dog is Fang Kuaiti that a middle part was equipped with the screw hole, and the dog passes the screw hole through the bolt to be fixed on accurate guide rail both ends. Further, the precise guide rail is a precise linear guide rail. Further, the bottom plate is a flat plate with higher flatness.
