Description
Technical Field
The invention belongs to the field of machine manufacturing, and particularly relates to a conical surface sealing surface correction tool.
Background
The sealing surface of the connection between the mechanical finished accessory of the airplane and the flared guide pipe adopts a conical surface, and the test of the finished accessory also needs to be carried out by connecting the conical surface with a process test tool. For a part of finished accessories which need to bear high pressure, the sealing surface needs to be tightly attached, and if the conical surface is damaged by collision, scratch, extrusion deformation and the like, the sealing surface cannot be sealed, so that the performance of the finished accessories is influenced.
For the damaged sealing conical surface, how to repair the sealing conical surface under the condition of not disassembling and disassembling the assembly has certain difficulty, and the main reasons are as follows: firstly, if the finished accessory belongs to the development and production of a bearing factory, a pipe nozzle can be subjected to lead sealing insurance, uncertain potential safety hazards exist in the pipe nozzle dismantling process, meanwhile, the conical surface of the pipe nozzle and threads have coaxiality requirements, if the sealing conical surface is simply repaired, the repaired sealing surface and the thread coaxiality are bound to generate deviation, and the finished accessory pipe nozzle cannot be sealed due to the deviation of the axis of the sealing surface after being connected with a guide pipe through the threads; and secondly, the conical surfaces of the nozzles are finished under the condition of one-time clamping, the mounting surfaces are more blank surfaces which are not processed, and the restoration of the reference surface is difficult to ensure by secondary clamping, so that the damaged conical surfaces are difficult to repair. Meanwhile, if the mode is adopted for repair, not only high requirements are put forward on the operation skills, but also the repair period of the workpiece is long, and the part of the repaired workpiece needs to be reassembled and tested, so that the repair period is prolonged.
Disclosure of Invention
In order to solve the defects of the prior art, namely the repair problem of the conical surface sealing surface, particularly the problems of potential safety hazard caused by the repair and the disassembly of the conical surface sealing surface, the possibility of generating deviation on the coaxiality of the conical surface sealing surface due to the reassembling after the repair and the long repair period, high requirement on the skill of a worker and the like, the invention provides a simple conical surface sealing surface correction tool, so that the damaged conical surface sealing surface can be quickly repaired under the condition of not detaching or partially detaching, and the sealing performance requirement can be met.
The conical surface sealing surface tool disclosed by the invention consists of a positioning sleeve, a conical surface correcting blade and a fixed screwing clamp. The inner thread of the positioning sleeve is in threaded connection with the outer thread of the workpiece to be repaired, and the form and position tolerance of the inner thread and the inner hole of the positioning sleeve meets the index requirement of the machining tolerance of the sealing surface; the conical surface correcting blade is sleeved in the fixed screwing clamp, and the fit clearance between the outer cylindrical surface of the conical surface correcting blade and the inner hole of the positioning sleeve meets the coaxiality requirement; the internal thread of the fixed screwing clamp is connected with the external thread of the positioning sleeve through threads. When the conical surface repairing tool is used, after the clamp is fixedly screwed and a workpiece is tightly clamped, the conical surface modifying blade applies downward and rotating torque to mill a damaged surface, so that the effect of repairing the damaged conical surface sealing surface is achieved. Aiming at the repair of the conical surface sealing surfaces of the threaded nozzles with different specifications, the conical surface correction blade with the corresponding specification can be replaced so as to meet the repair requirement.
Considering that the threads of the workpiece to be repaired are different in length, the adjusting gasket is additionally arranged between the workpiece and the positioning sleeve according to needs, so that the workpiece is tightly attached to the surface of the positioning sleeve and cannot rotate.
In the technical scheme, the conical surface sealing surface of the workpiece is installed on the correcting tool and then fixed on the clamp stand only by means of the universal clamp stand, the conical surface sealing surface is extruded by a blade made of rotary tool steel by adopting a universal wrench, the effect of repairing the conical surface sealing surface is realized, and the consistency of the sealing surface and the thread axis is ensured.
