Reference numeral 1 denotes a base body, and this base body 1 has a base joint surface 3 to be joined to a base 2 of a grinding machine, and a mounting surface 5 for a gauge block 4. A hinge block 7 for forming a hinge portion 6 is fixed to one side of the base body 1. Further, a movable body 8 rotatably held by the hinge portion 6 is provided. A roller 9 is attached to the lower surface of the movable body 8 at a predetermined distance from the center of rotation of the hinge portion 6 . Also, this roller 9
is in contact with the mounting surface 5, the movable body 8
A sliding surface 10 parallel to the base joint surface 3 and a sliding surface 11 perpendicular to the base joint surface 3 are formed on the upper surface and end surface of the base. The sliding surfaces 10 and 11 are formed as the bottom surfaces of grooves 12 and 13 having a constant depth. Thus, the dresser block 1 has a stepped portion 14 matching the depth of the grooves 12 and 13.
5 and 16 are provided, and this dresser block 1
5 and 16 have dressers 17 and 18 fixed to them, and knobs 19 and 20 that protrude from the sides are provided. Also, dresser block 15,1
Holders 15a and 16a are provided which are joined to the step portions 14 of No. 6 to prevent them from coming off. In addition, 2
1 is a grindstone, and 22 is its grinding surface.

Therefore, the roller 9 is brought into contact with the gauge block 4 placed on the mounting surface 5, and by adjusting the thickness of the gauge block 4, the angle of the dressers 15, 16 with respect to the base joint surface 3 can be set. Ru. In the state shown in FIG. 3, since the angle of the grinding surface 22 of the grindstone 21 with respect to the vertical plane is small, the dresser block 16 is manually slid in the vertical direction to dress the grinding surface 22 of the grindstone 21 with the dresser 18. Also, the grinding surface 2 relative to the vertical surface

Problems to be Solved by the Invention Therefore, even if the angle of the grinding surface of the grindstone 21 with respect to the vertical plane changes in the range of 0 degrees to 90 degrees, it is necessary to select one of the dresser blocks 15 and 16 for dressing. Can be done. For this reason, the movable body 8
There is no need to tilt the
The inclination angle of the movable body 8 can be set accurately,
This allows dressing to be performed in a stable state.

On the other hand, since two dresser blocks 15 and 16 are required to hold the dressers 17 and 18, respectively, the number of parts increases. Also, groove 1 that bends at 90 degrees
In order to form 2 and 13, it is necessary to set the workpiece twice on the machine tool, which makes machining troublesome.

Means for solving the problem A base body is provided which has a mounting surface on which the gauge block is mounted parallel to the base joint surface, and a movable body is rotatably connected to one side of this base body by a hinge part, and A protrusion that comes into contact with the writing surface or the upper surface of the gauge block on this mounting surface is located at a predetermined distance from the hinge portion and is provided on the lower surface of the movable body, and the upper surface and end surface of the movable body are connected to each other. two sliding surfaces that are perpendicular to each other and continuous through smooth curved surfaces, and linear grooves with openings at both ends fitted in the upper surface and end surface of the movable body; A dresser block is provided that is selectively slid manually between the moving surfaces and these sliding surfaces.

Therefore, by directly joining the protrusion of the movable body to the mounting surface, or by joining the protrusion to a gauge block whose thickness is adjusted and placed on the mounting surface, it is possible to The inclination angle of the movable body is freely changed from 0 degrees, and accordingly, the two sliding surfaces are freely tilted from the vertical or horizontal state, and the dresser block is slid along the sliding surfaces, thereby, When dressing the grindstone, select the sliding surface on which the dresser block will slide depending on the angle of the grinding surface of the grinding wheel relative to the vertical surface. Even if the angle of inclination of the movable body is limited to a maximum of 45 degrees, only one dresser block is required, and the top and end surfaces of the movable body are smooth, and the grooves of the dresser block are smooth at both ends. Since it is a straight line with an opening, it is possible to easily process the movable body and the dresser block.

Embodiment An embodiment of this invention will be described based on FIGS. 1 and 2. The same parts as those of the conventional example explained in FIGS. 3 to 5 are designated by the same reference numerals, and explanations thereof will be omitted. A roller 9, which is a protrusion, is provided on the lower surface of the movable body 8 at a fixed position separated from the hinge part 6 by a certain distance. The upper surface and the end surface of the movable body 8 have two sliding surfaces 23, 2 that are perpendicular to each other.
4 is formed. These sliding surfaces 23, 24
The space between them is connected by a smooth curved surface 31. Furthermore, when the roller 9 is in direct contact with the mounting surface 5, the sliding surface 23 is parallel to the base joint surface 3, and the sliding surface 24 is perpendicular to the base joint surface 3. Further, one dresser block 25 holding the dresser 17 is provided, and this dresser block 25 is formed with a linear groove 26 having openings at both ends, which is fitted into the upper surface and end surface of the movable body 8, and on both side surfaces. A handle 27 and a pin 28 are provided upright. Furthermore, pins 29 are provided on both sides of the movable body 8.
are erected, and both ends of a spring 30 are stretched between these pins 28 and 29.

In such a configuration, the grinding surface 2 of the grindstone 21
2, a gauge block 4 of a predetermined thickness is placed on the mounting surface 5, a roller 9 is brought into contact with the upper surface of this gauge block 4, and the inclination angle of the movable body 8, that is, the base The angle of the sliding surfaces 23 and 24 with respect to the joint surface 3 is set.

In the state shown by the solid line in FIG. 1, the angle α of the grinding surface 22 of the grindstone 21 with respect to the vertical plane is less than 45 degrees.
In this case, the angle of the sliding surface 24 with respect to the vertical plane is α
In this state, the grindstone 21 is rotated, the dresser block 25 is slid along the sliding surface 24, and the dresser 17 is brought into contact with the grinding surface 22. This performs dressing.

The angle of the grinding surface 22 of the grindstone 21 with respect to the vertical plane is
If β is smaller than 45 degrees, the angle of the sliding surface 23 with respect to the vertical plane is made equal to β, and the dresser block 25 is moved toward the sliding surface 23 as shown by the imaginary line in FIG. In this state, the whetstone 21
rotate the dresser block 25 to the sliding surface 23.
by sliding the dresser 17 along the grinding surface 22.
comes into contact with. This performs dressing.

Furthermore, in a state where the gauge block 4 is not interposed, the dresser block 25 is attached along the sliding surface 23.
Since it can be slid parallel to the base joint surface 3, it can be used as a parallel dresser.

As described above, since the sliding surfaces 23 and 24 are perpendicular to each other, the angle of the sliding surface 24 with respect to the base joint surface 3 is the supplementary angle of the inclination angle of the sliding surface 23 with respect to the base joint surface 3. . That is, when the sliding surface 23 is inclined at 20 degrees with respect to the base joint surface 3, the angle of the sliding surface 24 with respect to the base joint surface 3 is 70 degrees. Therefore, even if the angle of the grinding surface 22 of the grindstone 21 with respect to the vertical plane changes from 0 degrees to 90 degrees, the sliding surface 2 on which the dresser block 25 slides
By selecting 3 and 24, it is not necessary to tilt the movable body 8 by more than 45 degrees. Further, only one dresser block 25 is required. Furthermore, since the upper surface and end surface of the movable body 8 are flat and simple, manufacturing is easy, and the grooves 26 of the dresser block 25 are open at both ends and are linear, so machining is easy.

Effects of the invention Since this invention is constructed as described above, the inclination angle of the movable body can be freely changed from 0 degrees, and accordingly, the two sliding surfaces can be freely inclined from the vertical or horizontal state, and the dresser block can be The grinding wheel is dressed by sliding it along the sliding surface. Depending on the angle of the grinding surface of the grinding wheel with respect to the vertical plane, the sliding surface on which the dressing block is slid is selected, and the dressing of the grinding wheel is Even if the grinding surface changes from 0 degrees to 90 degrees with respect to the vertical plane, only one dresser block can be used while satisfying the requirement of limiting the tilt angle of the movable body to a maximum of 45 degrees. Since the upper surface and end surface of the movable body are smooth and the groove of the dresser block is linear with both ends open, the movable body and the dresser block can be easily machined.
