構成している。As shown in FIGS. 1 and 2, this type of conventional grinding device has upper and lower rotating shafts 3 and 4 that are rotationally driven by upper and lower electric motors 1 and 2 via transmission mechanisms (not shown), respectively. Grinding wheels 9 and 10 are mounted on grinding wheels 7 and 8, which are supported by upper and lower frames 5 and 6, respectively, and mounted on corresponding shaft ends of both rotating shafts 3 and 4, respectively, so that their grinding surfaces face each other. A carrier plate 11 that rotates in a plane perpendicular to at least one of the rotation axes 3 and 4 of both the grinding wheels 9 and 10 is arranged between the two grinding wheels 9 and 10, and an appropriate number of wheels are placed on the carrier plate 11. Accommodating parts 12, 12, . Due to the rotational movement of the whetstones 9 and 10, the upper and lower end surfaces of the whetstones 9 and 10 are
The workpiece W is moved in a sandwiched position between the workpieces 10 and 10, and the upper and lower end surfaces of the workpiece W are simultaneously ground by the grindstones 9 and 10.

ている。In the above-mentioned grinding device, the axis of the upper grinding wheel 9 is generally aligned with the lower grinding wheel 1 in order to give the workpiece W a cutting depth.
0, and the grinding conditions are set so that the gap between the grinding wheels 9 and 10 is narrower by the depth of cut at the grinding end point P' than at the grinding start point P of the workpiece W. It is set.

に対して所定角度だけ傾斜せしめていた。As a means for tilting the bag line of the upper whetstone 9 with respect to the axis of the lower whetstone 10, adjustment bolts 13 are installed at the four corners of the upper frame 5 that supports the rotating shaft 3 of the upper whetstone 9.
By vertically setting one of the four adjustment bolts 13 and adjusting the amount of rotation of these four adjusting bolts 13, the axis of the upper whetstone 9 can be set to the lower whetstone 10 via the upper frame 5 and the rotating shaft 3. It is tilted at a predetermined angle with respect to the base.

It is not located above or above, which makes setting the depth of cut very complicated and requires a great deal of effort and time to adjust.

。Moreover, after setting the depth of cut, the four adjustment bolts 13
When locking them, the mirror bevel angle of the upper frame 5, and therefore the inclination angle of the rotating shaft 3, may change slightly, and it may be necessary to redo the adjustment work. Obstacles to improvement that cannot be ignored were recognized. To explain in more detail, when adjusting the inclination angle of the rotating rock 3, the distance between the grinding surfaces of the grinding wheels 9 and 10 becomes the narrowest at a point S where the outer circumferential green of the grinding stone 9 occupies the lowest position. . In the double-head surface grinder as shown in the figure, a carrier that faces the grinding wheels 9 and 10 is installed so that the minimum grinding interval can be secured between the grinding wheels 9 and 10 at the grinding end point P' of the workpiece W. It is necessary to adjust the relative positions of the plates 11. That is, in order to improve the grinding accuracy of the workpiece W, the grindstone 9 must be kept at a predetermined depth of cut on the straight line T connecting the grinding end point P' and the rotation center ○ of the grindstone 9. It is necessary to set the grinding interval. However, as shown in FIG. 2, the straight line T is generally defined by two grindstone axes X and Y that are orthogonal to each other at the rotation center ○ of the grindstones 9 and 10.
When adjusting the grinding interval, the amount of displacement of the grinding wheel along the straight line T is determined based on the grinding wheel axis
the carrier plate 1 relative to the grinding wheels 9, 10 so that the combined displacement of both corresponds to the grinding interval.
It was necessary to adjust the relative position of 1, and a great deal of effort and time was spent on this adjustment work. It is an object of the present invention to provide a grinding device that solves the above-mentioned problems found in conventional double-headed surface grinders and that allows the adjustment of the inclination angle of the upper grindstone 9 to be performed quickly and with high precision. It is something to do.

てある。In view of this objective, the present invention, as shown in FIGS. 3 and 4, defines the grinding end point P' at which the workpiece W held on the carrier plate 11 comes out from between the upper and lower grinding wheels 9 and 10.
The center of rotation ○ of the grinding wheels 9 and 10 is placed approximately above one (for example, X) of the two grinding wheel axes X and Y that are orthogonal to each other, and the center 0' of the carrier plate 11 is brought to the grinding end point P'. The axis of the other grinding wheel (for example, Y in this example)
One side end 5a of the upper frame 5, which is spaced apart from the other by a predetermined distance e necessary to maintain the minimum grinding interval and rotatably supports the rotating shaft 3 of the upper grindstone 9, is connected to the other end via the bearing mechanism 14. The lower frame 6 is supported by one opposing side end 6a so as to be parallel to the grinding wheel axis Y, and the other side end 5b of the upper frame 5 is supported by the other side end 6a via the vertical movement mechanism 15. The gist of the grinding device is a grinding device supported on the other side end 6b of the lower frame 6 so as to be parallel to the grindstone axis Y of the grinding wheel. As shown in FIGS. 5 and 6, the bearing mechanism 14 is connected to the upper frame 5.
One side end 6a of the lower frame 6 is attached to the lower surface of the one side end 5a.

上廻る優れた効果を発揮し得るものである。In this way, the upper frame 5 swings relative to the lower frame 6 using the shaft 16 as a fulcrum, and as a result, the whetstone surface of the upper whetstone 9 is connected to the whetstone surface of the lower whetstone 10 via the upper frame 5 and the upper rotating shaft 3. On the other hand, I have to work hard. In this way, the minimum grinding interval that must be maintained between the two grinding wheels at the grinding end point P' where the workpiece W exits the grinding path passing through the grinding wheels 9 and 1 can be determined to be an arbitrary size. . That is, according to the apparatus of the present invention, the grinding end point P' where the workpiece W held on the carrier plate 11 comes out from between the upper and lower grinding wheels 9 and 10 is located on the x vehicle line of the grinding wheels 9 and 10. Therefore, by simply adjusting the inclination angle of the grinding wheel 9 along the X-axis direction, the distance between the two grinding wheels 9 and 10 at the workpiece delivery position of the carrier plate 11, that is, the grinding end point P' can be freely adjusted. It becomes possible to adjust to. Therefore, compared to the conventional method of complexly adjusting the oblique angle of the grinding wheel's rotation axis along two mutually perpendicular marilines at the center of rotation of the grinding wheel, the adjustment work is extremely quick and accurate. can be carried out. As can be understood from the above explanation,
According to the apparatus of the present invention, it is possible to set an accurate workpiece grinding interval between the upper grindstone and the lower grindstone disposed opposite thereto by simply pivoting the upper grindstone in one direction.
Therefore, the present invention can exhibit excellent effects that greatly exceed the level of conventional devices in improving the productivity of processing lines and improving the dimensional accuracy of workpieces.
