Description

Device for cleaning residual glue in threaded hole Technical Field The utility model relates to the technical field of cleaning of residual glue in threaded holes, in particular to a device for cleaning residual glue in threaded holes. Background The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. In order to avoid loosening of the bolt, when the bolt is installed, the anti-loosening effect of the bolt is often improved by coating a thread locking adhesive, the risk of loosening of the bolt is reduced, and in addition, the waterproof and antirust capabilities of the accessory are improved by coating a silicone sealant for part of working conditions. However, when the product is overhauled, a plurality of thread locking adhesives and sealing adhesives are left in the threaded holes and the thread bottom holes after the bolts are disassembled, the sealing adhesives are difficult to clean after being cured, huge workload is brought to operators, and the assembly of the components is affected. There is the clear device of gluing that provides the screw hole among the prior art, and cutter body cavity sets up, and cutter body sets up the concave part that is used for storing the incomplete glue, and cutter body head sets up the cutting head, has the following several aspects of problem: The cutter body and the cutting head are of an integrated structure and are used for cleaning the threaded hole and the threaded bottom hole at the same time, but residual glue in the threaded bottom hole is difficult to process, so that the cutter body needs to be rotated all the time to clean the residual glue in the threaded bottom hole through the cutting head in order to ensure effective cleaning of the residual glue in the threaded bottom hole, and the cutter body is in continuous rotation, and the inner wall of the threaded hole is easily damaged because the cutter body is in continuous contact with the inner wall of the threaded hole; The cutting head is of a planar structure, so that the residual glue in the sharp thread bottom hole is difficult to crush; Some screw holes are deeper, in order to realize cleaning, the cutter body needs to be arranged longer, the cleaning tool can only be suitable for screw holes with one specification, screw holes with different depths cannot be met, and aiming at shallower screw holes, only the cleaning depth of the tool can be controlled manually, so that a screw bottom hole is easy to damage; The cutter body is hollow, and the concave part is linked together with the cutter body, and the incomplete glue is left in the screw hole through the cutter body easily when getting into the concave part, certainly can also clear up after the cutter body leaves the screw hole, but the effect that the concave part set up receives the influence. Disclosure of utility model The first object of the present utility model is to provide a device for cleaning residual glue in threaded holes, which solves the problem of difficult cleaning of residual glue in threaded holes, and meanwhile, the device can not damage threads and threaded holes.
