A sharpening whetstone 18 is supported laterally by the groove 7 and pressed between a rubber plate 17' attached to the inner bottom surface of the insertion groove 17 and the whetstone holder 16, and the tip thereof is connected to the connecting plate 11. a hydraulic cylinder 2 fixed to the coupling body 8 for actuating the piston rod 19;
0. By rotating the lever 15 clockwise against the spring 14 using the pin 13 as a fulcrum, the sharpening whetstone 18 is released from the pressure of the whetstone holder 16 and can be removed from the whetstone head 12 and replaced. When the lever 15 is left unattended, the sharpening whetstone 18 is firmly fixed to the whetstone head 12 via the whetstone holder 16 by the elastic force of the spring 14, and fluid pressure is applied to the cylinder 20.

台１２への固定は確実である。 With this structure, during normal tool grinding, the tightening screw 6 of the holding member 4 is loosened, the dressing device 7 is pivoted to the chain line position shown in FIG. The dressing device 7 is tightened to fix the dressing device 7, and in this state, the work table 30 to which the object to be ground, such as a tool, is fixed is moved to the work table 30 by operating the handle 25 for raising and lowering the grindstone, the handle 31 for cross sliding of the work table 30, etc. After adjusting the grinding surface of the object to be ground by the side surface of the grinding wheel 1, a certain number of objects are ground by automatic forward and backward movement of the grindstone head 26 and automatic fine movement movement of the work table 30 to the left. Objects are sequentially ground using a grinding wheel 1.
During this grinding operation, if the grinding wheel 1 becomes clogged and the grinding of the object to be ground becomes unsatisfactory, loosen the tightening screw 6 and pivot the dressing device 7 to the position shown by the solid line in Fig. 1. After fixing it in this position, the connecting plate 11 is then manually moved to the left as necessary, and the driving source inside the casing 33 is activated by a foot switch or push button (not shown), and the cylinder 20 is activated as shown in FIG. The piston rod 19 is connected to the connecting plate 1.
1 is connected to the guide shaft 9 and the guide tube 10 under the guidance of the connecting body 8.
Since both of them are moved gently to the left, the tip of the sharpening whetstone 18, which is firmly fixed to the whetstone head 12 attached to the connecting plate 11, is attached to the side surface of the grinding whetstone 1 in a rotating state while grinding the object to be ground. The grinding wheel 1 is sharpened by being pressed against the casing 33, and this sharpening work is stopped after a certain period of time by opening and closing a solenoid valve operated by a timer (not shown), and the drive source inside the casing 33 is also activated. Both will be suspended. When the dressing work of the grinding wheel 1 is completed in this manner, the dressing device 7 may be fixed at the position shown by the chain line in FIG. 1 using the tightening screw 6 as necessary to continue grinding the object to be ground. Therefore, when the sharpening whetstone 18 becomes worn, by rotating the lever 15 clockwise, the whetstone holder 16 moves up and down against the elastic force of the spring 14, so that the pressure on the whetstone holder 16 is released. The sharpening whetstone 18 can be easily pulled out from the insertion groove 17, and when installing the sharpening whetstone 18, it is only necessary to perform the operation opposite to the above, and,
Since the pressing member 23 of the grindstone holder 16 has a universal joint shape connected to the spherical part of the connecting member 22,
The pressing surface of the pressing member 23 that presses the sharpening stone 18 can have a degree of freedom, and the sharpening stone 18 can be securely fixed to the grindstone stand 12.

ものである。(Effects of the Invention) As is clear from the above description, the present invention is such that the dressing wheel of the dressing device, which is brought into contact with and separated from the grinding surface of the grinding wheel of the grinding machine body by means of a cylinder, is inserted into the push-in groove of the grinding wheel head. It is fixed by the whetstone holder which is spring-loaded by a spring, and the pressing member of the whetstone holder is attached to the lever and connected to the spherical part of the connecting member to form a universal joint, so the pressing surface of the pressing member is free. The sharpness is large and the sharpening stone can always be held in an appropriate state, and the pressure of the sharpening stone holder on the sharpening stone can be easily released by pivoting the lever, so that replacement work can be completed in a short time. Moreover, since there is no need to adjust the mounting position, there are various advantages such as fewer interruptions in grinding work and the ability to significantly increase the number of grinding operations, solving the problems of conventional grinders. It has an extremely large practical value.
