Description

Technical Field

[0001] The invention relates to the technical field of engine processing, and in particular to an engine inner wall and blade grinding device based on protection technology. Background Art

[0002] An aircraft engine is a highly complex and sophisticated thermal machine. As the heart of an aircraft, it is not only the driving force for the aircraft to fly, but also an important driving force for the development of the aviation industry. Every important change in the history of human aviation is closely related to the technological progress of aircraft engines. During the processing of aircraft engines, grinding devices are needed to grind and polish the inner walls and blades to facilitate the smooth progress of subsequent work.

[0003] The existing technical solutions have the following deficiencies:

[0004] First, the existing engine grinding device has a relatively simple structure in terms of clamping, and can only clamp workpieces of the same general shape, either rectangular or arc-shaped workpieces, but the engine blades are irregular shapes, and the traditional clamping seat satisfies the clamping conditions. Therefore, the clamping limit structure is relatively simple, and further improvement and optimization are needed;

[0005] Second, the existing engine grinding device can only perform separate grinding and polishing on the inner wall or blades of the engine. Such operation is not only cumbersome, but also prolongs the working time, greatly reduces the working efficiency, and makes it difficult for the subsequent processing work to proceed smoothly and efficiently.

[0006] Third, the grinding components in the existing engine grinding devices are not easy to disassemble for cleaning or replacement, and the users are also troublesome in daily operation. Therefore, there is still room for improvement in the process of disassembling and installing the grinding components.

[0007] Therefore, we need to design a kind of engine inner wall and blade polishing device based on protection technology to solve the above-mentioned problem. Summary of the invention

[0008] The object of the present invention is to provide an engine inner wall and blade grinding device based on protection technology to solve the problem of the relatively simple structure of the workpiece clamped by the existing grinding device mentioned in the above background technology.

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an engine inner wall and blade grinding device based on protection technology, comprising a grinding box, a second connecting ring is fixed to the outer side of the top of the grinding box, and a first connecting ring is connected above the second connecting ring, a grinding assembly cover is fixed to the inner side of the first connecting ring, and a first motor is fixed above the grinding assembly cover, a support frame is fixed below the grinding box, a first rotating shaft is fixed at the output end of the first motor, and a ring sleeve plate is fixed to the outer side of the first rotating shaft, a grinding roller is fixed below the ring sleeve plate, a third bevel gear is fixed to the outer side of the first rotating shaft, a second rotating shaft is rotatably connected below the first rotating shaft, and a first bevel gear is fixed to the outer side above the second rotating shaft, the first bevel gear and the third bevel gear are meshed and connected through the second bevel gear, a second connecting plate is fixed below the second rotating shaft, and an electric push rod is fixed below the second connecting plate, a first connecting plate is fixed below the electric push rod, and a grinding head is fixed below the first connecting plate.

[0010] Preferably, a bearing seat is fixed inside the grinding box, and a first forward and reverse thread screw is rotatably connected inside the bearing seat, a first threaded sleeve is sleeved on the outer side of the first forward and reverse thread screw, and a connecting seat is fixed above the first threaded sleeve, an electric wheel is rotatably connected to the outer side of the grinding box, and the output end of the electric wheel is rotatably connected to the first forward and reverse thread screw.

[0011] Preferably, a special-shaped clamping seat is connected to the top of the connecting seat, and the inside of the special-shaped clamping seat is rotatably connected to the second connecting shaft, a second clamping plate is fixed above the second connecting shaft, and the inside of the second clamping plate is rotatably connected to the first connecting shaft, a first clamping plate is fixed above the first connecting shaft, and flexible elastic parts are distributed on the inner side of the first clamping plate.

[0012] Preferably, a handwheel is fixed to the outer side of the special-shaped clamping seat, a built-in groove is opened inside the special-shaped clamping seat, and a second forward and reverse screw is rotatably connected inside the built-in groove, the second forward and reverse screw is rotatably connected to the handwheel, a second threaded sleeve is sleeved on the outer side of the second forward and reverse screw, and a fixing block is fixed below the second threaded sleeve, a fixing groove is opened inside the connecting seat, and the fixing block is snap-fitted and connected to the fixing groove.

[0013] Preferably, the width of the fixing block is equal to the width of the fixing groove, and the shape of the fixing block is set to be L-shaped.

[0014] Preferably, a through groove is provided inside the first connecting ring, and a turning bar is rotatably connected inside the through groove, a turning knob is fixed above the turning bar, and anti-slip teeth are distributed on the bottom end of the turning knob, a turning block is fixed below the turning bar, and a turning groove is provided inside the second connecting ring, and the turning groove and the turning block are rotatably connected.

[0015] Preferably, the anti-slip teeth are triangular in shape and are arranged at equal intervals along the edge of the bottom end of the knob.

[0016] Preferably, the elastic flexible member is made of rubber. The flexibility of the rubber material can not only clamp workpieces of different shapes but also protect the workpieces to prevent the special-shaped clamping seat from causing certain damage to the workpiece under hard clamping.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) By starting the first motor to drive the first rotating shaft and the outer ring plate to rotate, the grinding roller is further caused to move in a circular motion around the axis of the grinding box to start grinding the inner wall. The first rotating shaft rotates and under the action of the gear meshing connection, it drives the second rotating shaft to rotate in the opposite direction, and under the action of the electric push rod, it can drive the grinding head to start grinding work, so that the inner wall and the blade of the engine can be synchronously polished, saving the grinding work time, thereby improving the work efficiency, so that the subsequent processing work can be carried out efficiently and smoothly;

[0019] (2) By rotating the electric wheel and under the action of the threaded connection, the two groups of special-shaped clamping seats can be driven inward synchronously to clamp and limit the blade in the center. When the special-shaped clamping seat touches the edge of the blade, the second connecting shaft can be used to rotate the direction of the second clamping plate so that it can be as close to the edge of the blade as possible. When further clamping, the second clamping plate will also drive the first clamping plate to rotate so that it is attached to the outside of the blade, thereby achieving the effect of special-shaped clamping. When the special-shaped clamping seat needs to be replaced, the hand wheel is turned, and under the action of the threaded connection, the fixing block is pulled out from the inside of the fixing groove, thereby separating the special-shaped clamping seat from the connecting seat, and then the special-shaped clamping seat can be replaced and repaired, thereby extending its service life and use value.
