Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an end face dressing device for grinding the side surface area of a grinding wheel used in a cylindrical grinder, a surface grinder, a tool type grinder, a centerless grinder, etc. be.

[Conventional technology]

Conventionally, there is an end face dressing device of this type, as disclosed in Japanese Utility Model Application Publication No. 53-155193.

[Problem that the invention attempts to solve]

In the above-mentioned conventional grinding wheel, the grinding oil is sprayed onto the rotating grindstone from a fixed position, so the sprayed grinding oil scatters and cannot be sprayed efficiently. Therefore, there are problems such as the generation of grindstone dust cannot be prevented and the grinding oil pot must be operated each time.

An object of the present invention is to solve the above-mentioned conventional problems and to provide an end face dressing device that can spray grinding oil efficiently and prevent grindstone dust.

[Means for solving problems]

In order to achieve the above object, the present invention rotatably inserts a shaft tube equipped with a manual handle into an insertion hole provided in the main body, and allows the forward and backward shaft holding the bond diamond holder to rotate together with the shaft tube. In the grinding wheel end face dressing device, a rotating disk having an oil injection nozzle is integrally provided at the tip of the shaft tube, and a cut-out circle communicating with the oil injection nozzle attached to the periphery of the rotating disk is provided on the front of the main body. A groove is recessed to communicate with the oil supply hole formed in the main body, and an oil passage hole leading to the bond diamond is also provided in the bond diamond holder facing the oil injection nozzle.

〔Example〕

In the figure, reference numeral 1 denotes the main body of the device, which, as shown in FIG. Insert the shaft tube 4. Incidentally, the inclined tip edge 2'
is in contact with the cover b of the rotating grindstone a.

The shaft tube 4 is integrally provided with a rotary disk 5 at its tip, and an oil injection nozzle 6 is attached to its periphery. The threaded portion 4' at the rear end is made to protrude outside the insertion hole 3, and a manual handle 8 is protruded through the collar 7, into which an internally threaded ring 9 is screwed.

The bulging portion 2 of the main body 1 has a circular groove 10 recessed in the front face 2'', the circular groove 10 is communicated with the oil supply hole 11 provided in the main body 1, and the oil injection nozzle 6 is aligned with the circular groove 10. The oil injection nozzle 6 and the circular groove 10 communicate with each other when the shaft tube 4 rotates except for the circular groove 12.An O-ring 13 is fitted in the front surface 2''. .

In addition, the forward and backward shaft 14 is inserted into the shaft tube 4, a holder 15 is attached to the tip protruding from the shaft tube 4, and a fixed tube 17 for supporting the bond diamond 16 is inserted into the holder 15 at a position facing the oil injection nozzle 6. It's worn. A female thread 18 is formed at the rear of the advance/retreat shaft 14 and a screw rod 19 is screwed into the screw rod 19, and the screw rod 19 is connected to the dial 22 by a fixing screw 21 via a thrust plate 20.
is attached and operated to move the advance/retreat shaft 14 forward or backward. Furthermore, a pin 24 is attached to the shaft tube 4 to fit into a guide groove 23 formed in the forward and backward shaft 14. 25 is an oil seal provided on the rotary disk 5 of the shaft tube.

[Operation of the idea]

When the shaft tube 4 is rotated by the manual handle 8, the bond diamond 16 moves from the position shown by the solid line to the position shown by the chain line as shown in FIG. At that time, oil injection nozzle 6
rotates together with the bond diamond 16 and constantly sprays oil through the occluded groove 10.
Supply grinding oil to the grinding section. When the oil injection nozzle 6 reaches the circular cutout 12, the bond diamond 16 is separated from the rotary grindstone a, the oil path is cut off, and the supply of grinding oil is automatically stopped.

[Effect of idea]

According to the present invention, since the grinding oil injection nozzle is linked to the bond diamond, there is no need for grinding wheel dust and there is no need for a valve or the like as in the conventional case, and the grinding oil can be sprayed efficiently.

[Brief explanation of the drawing]

The drawings show an embodiment of the dressing device for the end face of a grinding wheel for a grinding machine according to the present invention, in which FIG. 1 is a side view, FIG. 2 is a front view, and FIG. 3 is a sectional side view. 1...Main body, 2...Bulging part, 2''...Front, 3
