Abstract

(57) [Summary] (Correction) [Purpose] The seat surface of the marine component main body is finely ground. [Structure] A device for rotating a valve body having a seat surface, a rotary grindstone 14 rotated by a grinding motor 15 at a position obliquely below the seat surface, and the rotary grindstone 14 lifted up and down on the seat surface. And a feed screw rod 8 for lifting and lowering, and a slanting rod 16 for obliquely moving the grindstone 14 in and out of the seat surface in a diagonal direction, and the rotary grindstone 14 in and out horizontally. And a horizontal minute feed screw 19 for press-contacting with each other. The rotation of the horizontal minute feed screw 19 causes the rotary grindstone 14 to move slightly in the horizontal direction to finely polish the sheet surface. It has characteristics.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a polishing device for a marine valve used in a ship or the like.

[0002]

[Prior art]

 In the prior art, when polishing the inverted conical surface of the valve, the main body of the polishing machine was moved in two directions, that is, vertical movement and diagonal movement.

[0003]

[Problems to be solved by the device]

 The above-mentioned prior art has the drawbacks that it is difficult to cope with the size of the valve and it is difficult to evenly polish the valve by cutting into the inverted conical surface of the valve and grinding or chipping it.

[0004]

[Means for Solving the Problems]

 According to the present invention, when the sheet surface of the valve body is polished by the main body of the polishing machine, the respective parts of the main body of the polishing machine can be vertically moved vertically, obliquely moved in and out, and moved horizontally in and out, and the rotary grindstone, which is the polishing section, is moved to the seat surface. Pressure contact.

[0005]

[Action]

 Rotation of the lifting handle raises and lowers the polishing machine body through the bevel gear, lifting feed screw rod, and lifting base, and brings the rotating grindstone into contact with the surface to be polished of the valve body, then rotating the diagonal handle. When the rotary whetstone is slanted in and out through the slanting rod for moving in and out and the table for slanting in and out, the surface to be polished of the valve body is polished, and the horizontal feed screw rod and the horizontal moving base are also rotated by rotating the minute polishing handle. The surface of the valve body to be polished is finely ground by moving the rotary grindstone horizontally through a disk.

【Example】

 Reference numeral 1 denotes a valve main body which is an object to be polished and is supported by a support member 2 and is rotated in a predetermined direction by a rotation of a motor 3 via a belt pulley mechanism 4. Reference numeral 5 denotes a seat surface of the valve body 1 which is a surface to be polished, and is made of a hard material which is not easily corroded by exhaust gas. 6 is a valve seat of the valve housing 7. Reference numeral 8 is a vertical feed screw rod mounted vertically on a base plate 9. By rotating the vertical handle 10, a bevel gear screwed with the vertical feed screw rod 8 of a bevel gear system 11 is rotated to attach a vertical base member 12 to a slide base. It is designed to move up and down through the plate 13. Then, a rotary grindstone 14 to be described later ascends and descends in the vertical direction together with the grinding motor 15 and comes into contact with the seat surface 5 of the valve body 1.

Reference numeral 16 denotes an oblique entrance / exit screw bar diagonally attached to the elevating / lowering base board 12 to rotate the oblique entrance / exit handle 17 to rotate the oblique entrance / exit screw bar 16 so that the oblique entrance / exit table 18 is slanted. Further, the rotary grindstone 14 is moved together with the grinding motor 15 so as to come into contact with the seat surface 5 of the valve body 1. A grinding motor 15 equipped with the above-mentioned rotary grindstone 14 is connected to the oblique loading / unloading table 18.

Reference numeral 19 denotes a horizontal minute feed screw rod horizontally attached to the elevating base plate 12, and the horizontal minute feed screw rod 19 is rotated by a minute rotation operation of the minute polishing handle 20 so that a horizontal movement table 21 is provided. The horizontal moving member 22 is moved in the horizontal direction, and the rotary grindstone 14 is moved in the horizontal direction together with the grinding motor 15. Reference numeral 23 denotes a scale ring, which indicates the amount of rotation operation of the fine polishing handle 20. In the present embodiment, the horizontal movement amount of the rotary grindstone 14 is set to 5/1000 mm by rotating the fine grinding handle 20 by one scale.

Next, the operation mode will be described. The valve body 1 is supported by the support member 2, and the motor 3 is rotated to rotate the valve body 1 in a predetermined direction. Then, the elevating handle 10 is rotated to rotate the bevel gear that engages the elevating feed screw 8 of the bevel gear system 11 to raise the elevating base member 12 in the direction of arrow A through the slide base mounting plate 13. At that time, since the horizontal moving member 22 and the grinding motor 15 are simultaneously raised in the same direction, the rotary grindstone 14 is also moved in the same direction and pressed against the seat surface 5 of the valve body 1.

Further, the diagonal entry / exit handle 18 is rotated to rotate the diagonal entry / exit screw rod 16, and the diagonal entry / exit table 18 is diagonally moved to move the rotary grindstone 14 together with the grinding motor 15 in the direction of arrow B. The whetstone 14 is pressed against the seat surface 5 of the valve body 1 to polish the seat surface 5. In this state, the horizontal minute feed screw 19 for minutely rotating the minute polishing handle 20 minutely rotates, and the horizontal moving member 22 horizontally moves in the arrow C direction via the horizontal moving table 21 to move together with the grinding motor 5. The rotary grindstone 14 press-contacts the seat surface 5 to finely grind the seat surface 5.

[0011]

[Effect of device]

 Thus, in the present invention, in particular, since the horizontal fine feed screw is provided, the rotating grindstone can be finely moved in the horizontal direction, and the width of the seat surface of the valve body can be adjusted and the polishing amount can be finely adjusted. The unevenness due to polishing can be prevented and the sheet surface can be made into a uniform surface and finished smoothly. In addition, it has the advantage of being able to deal with the wear of the rotating grindstone.
