Gasket plane rapping equipment inside and outside}

TECHNICAL FIELD The present invention relates to a gasket face lapping apparatus, and more particularly, to an inner and an outer gasket face lapping apparatus for providing uniform lapping pressure, verticality, and top view to a chamber entrance gasket face of a steam generator without using a hand tool.

In general, lapping on the gasket surface is intended to reduce radiation squeeze, reduce manpower, improve maintenance quality, and maintain convenience when processing the gasket surface of the steam generator compartment entrance.

In addition, the gasket surface can be processed in the case of the point corrosion corrosion of the water inlet and outlet gasket surface of various tanks, and has been applied in the precision processing of heat exchanger and entrance gasket surface corrosion of the power plant chemical plant.

However, conventionally, the gasket surface is removed by using hand tools such as sandpaper, brush, grindstone, and string to wrap the gasket surface of the water room entrance and exit of the steam generator, but restarts after replacing the gasket due to the defective lapping process and the floor plan. There have been several problems, such as frequent leakage of time.

Therefore, by providing the lapping pressure, verticality, and flatness of the machining surface to the entire area of the gasket, it is possible to obtain fast machining and excellent quality, to shorten the processing time and to provide a uniform machining surface, and to use the spring elastic modulus to make the lapping pressure. There is a need for a wrapping device that can provide a vertical plan view.

Therefore, the present invention has been proposed to solve the problems associated with the conventional lapping gasket surface as described above, the wrapping tool without the need for the operator to directly enter the inner and outer gasket surface of the water chamber entrance of the steam generator to wrap Its main purpose is to rotate after installation to uniformly provide the machining surface and plan view of the inner and outer gasket surface, and to remove scale and foreign matter.

The present invention for achieving the above object, the shaft, the front and rear lapping plate which is provided at a predetermined distance apart from the shaft, the spring cover and the lapping coupled to the shaft to elastically support the front and rear lapping plate An elastic restoring means installed between the surface of the plate, a body positioned between the front and rear lapping plates and rotatably coupled to the shaft, a rack bar installed on one side of the body for fixing the body, and a moving force on the rack bar. The clamp is installed to apply a, the first bevel gear coupled to the clamp and interlocked, the rack bar in engagement with the first bevel gear is engaged with the clamp and the first bevel gear and the stroke of the rack bar A second bevel gear that accurately transmits a distance, coupled to one end of the shaft, Surface is characterized in that the configuration formed by the handle for rotating the lapping plate.

The present invention is also characterized in that the elastic restoring means is formed as a spring, so that it is possible to provide a wrapping pressure, a vertical degree, and a top view by using the spring's elastic modulus.

Hereinafter, a gasket surface wrapping apparatus according to the present invention will be described with reference to the accompanying drawings.

In the accompanying drawings, FIG. 1 shows an overall cross-sectional view showing a wrapping apparatus according to the present invention.

The gasket surface wrapping apparatus according to the present invention includes a shaft 10 constituting a central axis, front and rear wrapping plates 31 and 32 provided at a predetermined distance from the shaft 10 and such front and rear wrapping plates 31 ( An elastic restoring means installed on the shaft 10 to elastically support the 32, the main body 20 connected between the front and rear lapping plates 31 and 32 and rotatably coupled to the shaft 10. The rack bar 21 is installed to secure the main body 20, the first and second bevel gears 25 and 28 and the clamp are installed to secure the main body 20 of the rack bar 21. 23, the shaft 10 is configured to include a handle 40 coupled to one end to rotate the front and rear lapping plates 31 and 32.

The shaft 10 is formed to serve to fix and rotate the front and rear wrapping plates 31 and 31, and the first support nut 11 is formed to adjust the tension of the spring 17, which is an elastic restoring means. The first spring cover 13 is formed to fix the spring 17.

Then, the spring guide 15 is formed to evenly distribute the wrapping pressure by positioning the spring 17, the front and rear wrapping plates 31, 32 are formed for lapping the gasket surface.

In addition, the main body 20 is formed to be connected to the shaft 10, the rack bar 21 is formed on one side is formed to accurately and firmly fix the main body 20.

In addition, the cover plate 22 is formed in the main body 20 to protect the first and second bevel gears 25 and 28 of the main body 20, and the rack bar 21 is installed by installing the clamp 23. To move.

In addition, to form a clamp cover 24 to protect the clamp 23, the first bevel gear 25 is connected to the rack bar 21 is formed to accurately transmit the stroke distance of the rack bar 21, bush The main body 20 is fixed to the boundary between the shaft 10 and the main body 20 so that the shaft 10 can be rotated.

Meanwhile, the first bevel gear 25 is formed to guide the rack bar 21 by forming the guide bar 27, and forms the second bevel gear 28, connected to the clamp 23, and positioned on the rack bar 21. The linear motion of the rack bar 21 by the clamp 23 and the first and second bevel gears 25 and 28 will be described. 23 has a ratchet function, such a clamp 23 is connected to the first bevel gear 25. Then, when the clamp 23 is rotated in the right direction, the first bevel gear 25 is rotated by interlocking the second bevel gear 28 engaged with each other. As the second bevel gear 28 rotates as described above, a small shaft that forms a screw (not shown) formed in the second bevel gear 28 rotates, and the rack bar 21 is rotated by the forward and reverse rotation of the screw. ) Has a linear motion to the main body 20.

In addition, the spring support 33 is formed to hold the position of the spring 17 and the second spring cover 35 is formed to adjust the tension control of the spring 17.

In addition, the second support nut 37 is formed to fix the spring cover 35, and the handle 40 is formed at one end of the shaft 10 to rotate the shaft 10.

Referring to the effect of the gasket surface wrapping apparatus of the present invention configured as described above are as follows.

First, after assembling the shaft 10 and the back lapping plate 32, the assembled structure is assembled with the main body 20. After the assembly with the main body 20 determines the up, down, left and right directions, the main body 20 and the shaft 10 are opened to an appropriate length.

Then, the back lapping plate 32 is first put in the lapping back side, and then the clamp 23 of the ratchet function is rotated to the left using a spanner to the main body 20. After the coupling to the wrapping surface in this way, the front wrapping plate 31 is assembled. Then, after adjusting the tension of the spring 17, the handle 40 is rotated.

As described above, the gasket surface wrapping apparatus according to the present invention allows the wrapping to be performed without using a hand tool to wrap the water chamber entrance and exit gasket surface of the steam generator, and in particular, the processing surface and flatness of the wrapping can be made uniform. It is a very useful invention.
