Detailed Description
Referring to fig. 1, the utility model provides a tool for ensuring the coaxiality of a pre-drilled hole, which comprises a checking shaft 2 and a checking shaft sleeve 3; the plurality of the inspection shaft sleeves 3 are sleeved outside the inspection shaft 2, and the inspection shaft sleeves 3 can freely move along the axial direction of the inspection shaft 2. According to the utility model, the traditional mode that a plurality of inspection shafts with different diameters are replaced by one inspection shaft and a plurality of inspection shaft sleeves 3 are sleeved on the inspection shaft is adopted, so that the dilemma that different inspection shafts are required for different apertures and the inspection shafts are not easy to withdraw is avoided. When in use, the proper shaft detecting sleeve 3 is selected according to the aperture of the pre-drilled holes, and the number of the shaft detecting sleeves 3 is selected according to the number of the plurality of pre-drilled holes. After the proper shaft detecting sleeve 3 is selected, a plurality of (at least two) shaft detecting sleeves 3 are respectively plugged into the pre-drilled holes, and meanwhile, the shaft detecting 2 is extended into the plurality of shaft detecting sleeves 3, and the shaft detecting sleeves 3 and the shaft detecting 2 can move relatively freely, so that the shaft detecting 2 can be conveniently and rapidly inserted into the shaft detecting sleeves 3, and finally the coaxial assurance of the plurality of pre-drilled holes is finished. By means of the fixture, the whole weight of the fixture can be reduced by adopting 45# steel with the diameter of 26mm, and the fixture is convenient to operate.
In some embodiments, the diameters of the pre-drilled holes are the same, so that a plurality of detection sleeves 3 with identical structures are required, that is, the inner diameters of the detection sleeves 3 are identical, the outer diameters of the detection sleeves 3 are identical, and the pre-drilled holes with the same diameters are directly and coaxially ensured through the identical outer diameters. However, in some embodiments, the diameters of the pre-drilled holes are unequal, for example, the pre-drilled holes comprise 3 pre-drilled holes, the diameters of the three pre-drilled holes are respectively 0.8cm, 0.9cm and 1.0cm, in the existing coaxial ensuring device, coaxial ensuring cannot be realized on the pre-drilled holes with different diameters, however, the inner diameters of the inspection shaft sleeves 3 adopted by the utility model are completely equal (ensuring that the inspection shaft 2 can be inserted and relatively freely moved), the outer diameters of the plurality of inspection shaft sleeves 3 are unequal, the inspection shaft sleeves with different outer diameters are respectively inserted into the pre-drilled holes with different diameters, and finally, the coaxial ensuring of the pre-drilled holes with different diameters is realized through the insertion of the inspection shaft 2. That is, the size of the inspection shaft sleeve 3 can be used for different pre-drilled holes by ensuring the aperture change of coaxiality according to the requirement.
In order to further improve the coaxiality of a plurality of pre-drilled holes, the inspection shaft 2 and the inspection shaft sleeve 3 are in clearance fit, and meanwhile, the clearance fit mode is convenient for rapidly withdrawing the inspection shaft 2 after the coaxial service is completed, so that the inspection shaft sleeve 3 is rapidly withdrawn under the condition of no interference of the inspection shaft 2.
