Regarding the grinding method of the grinding machine, the purpose is to perform high-precision grinding safely and quickly.A standard gauge with the required grinding dimensions is installed on the table in line with the workpiece, and a gauge is installed above the table. A non-contact distance meter is provided movably in the vertical direction at a position higher than the grinding wheel and facing the standard gauge, and as the table moves back and forth from side to side, the distance meter measures the standard gauge and the workpiece. When these measured distance values become equal, it is considered that the workpiece is completed and the grinding operation for the workpiece is stopped, and the standard gauge 4 at the initial completion of the workpiece is Non-contact distance meter 5
Using the distance measurement value as a reference value, the amount of wear on the grinding wheel is detected by comparing this reference value with the distance measurement value of the same standard gauge when the workpiece is completed after that, and if this amount of wear exceeds a preset value. In this case, the distance meter and the table are moved upward from the initial setting position by a distance equivalent to the amount of wear, and the grinding operation start position is kept constant.

However, in the above-mentioned grinding method using a rotary grindstone, the grindstone wears during grinding, making it difficult to finish the surface of the workpiece to the specified dimensions according to the cuts made by the grindstone. Grinding must be carried out while measuring the dimensions using a grinder, which is not desirable from a safety standpoint, and furthermore, the grinding table requires many reciprocating movements, resulting in an extremely large number of man-hours. Furthermore, even if automation was planned in the future, there was the problem of having to take measures against grinding wheel wear.

In order to achieve the above object, in the present invention, a table on which a workpiece is placed is reciprocated left and right and also moved upward, and a rotating grindstone placed above grinds the upper surface of the workpiece. In the grinding machine, a standard gauge having the required grinding dimensions is installed on the table in parallel with the workpiece, and a non-contact distance meter is installed above the table at a position higher than the grinding wheel and facing the standard gauge. is provided to be movable in the vertical direction, and as the table moves back and forth from side to side, the distance meter sequentially measures the distance between the standard gauge and the workpiece, and when these measured distance values become equal, the workpiece is completed. Considering this, the grinding operation for the workpiece is stopped, and the distance measurement value of the non-contact distance meter 5 with respect to the standard gauge 4 at the time of initial completion of the workpiece is set as a reference value, and this reference value is set. The amount of wear on the grinding wheel is detected by comparing it with the distance measured using the same standard gauge when the workpiece is completed, and if the amount of wear exceeds a preset value, the distance meter and table are worn away from the initial setting position. A grinding method is adopted in which the grinding operation start position is kept constant by moving the grinding member upward by a distance corresponding to the amount of the grinding member.

圧接し被加工物２のＣ面を研削するものである。 The table 1 performs reciprocating motion in the horizontal direction in the figure, that is, in the direction of the solid line arrow, with point A (Y axis) and point D (X axis) as the starting points (initial setting positions), and also in the vertical direction in the figure, that is, in the dotted line, for cutting movement. It is possible to move in the direction of the arrow. On the other hand, the grindstone 3 rotates around its axis, presses the workpiece 2 with its lower surface (polishing surface) B, and grinds the C surface of the workpiece 2.

応形式のものである。 The standard gauge 4 has a workpiece 2 on the table 1.
and have the required grinding dimension height H required. As shown in the figure, the mounting position is determined so that it does not come into contact with the outer circumference of the grindstone 3 near the point A. In addition, the non-contact distance meter 5 is opposed to the standard gauge 4 at a position higher than the grindstone 3 above the table 1 separated by a required distance L, and is moved up and down by a moving mechanism 5-1, that is, moved in the direction of the dotted arrow. is possible. This distance meter 5 used in this example uses a high-frequency coil, and when a conductor approaches the high-frequency coil, the so-called metal-sensitive sensor uses the phenomenon that an eddy current generated in the conductor causes a change in the inductance of the high-frequency coil. It is of the form.

得るものである。 When the power is turned on and activated, the table 1 will reciprocate left and right as indicated by the solid arrow. Therefore, the distance meter 5 alternately measures the distance between the corresponding standard gauge 4 and the workpiece 2 based on its reciprocating motion, and sequentially inputs the measured values to the controller 6. The controller 6 compares the two input interval values, coarsely feeds the table 1 in the direction of the dotted arrow, or increases the feed amount, until the deviation value between the two reaches a required value close to zero, and when the required value is reached, fine feed is started. Drive table 1 to do this. When it is detected that the respective interval values are equal, the grinding of the workpiece 2 is stopped and the table 1 is controlled by a drive mechanism (not shown) to return to the original positions A and D. By performing rough cutting and fine cutting in this way, the production of the workpiece 2 having the required dimensions is completed. Note that the movement of the table 1 in the direction of the dotted arrow for grinding is controlled so as to be performed at the timing when the table 1 is at the origin position A shown in FIG. Incidentally, rangefinder 5
The measurement output of the standard gauge can also be used to monitor the operating status of table 1. If the table movement becomes abnormal due to some kind of obstacle, there will be a large change in the measured value output.
Thereby, the drive of the table moving mechanism can be stopped. Therefore, this can be advantageous in terms of maintenance of the machine.

傷する問題がある。 Thereafter, the work is continued by replacing the workpiece 2. Although the required dimensions of the workpiece 2 can be obtained without any problems during this time, the grinding wheel 3
The polishing surface B of the grinding wheel 3 decreases due to wear, and therefore the distance between the polishing surface of the grindstone 3 and the origin position D of the table 1 increases. This means that the feed distance for moving the table 1 from the origin position D in the direction of the dotted arrow during grinding increases as the grinding wheel 3 wears, meaning that the play distance increases from the initial level, which is a drawback that reduces grinding efficiency. . In the worst case, the polishing surface of the grinding wheel 3 and the lower surface of the distance meter 5 are at the same height with respect to the table 1, and there is a problem that the distance meter comes into contact with the workpiece during grinding and is damaged.

耗量だけ距離計５をテーブル１から後退させる。 Therefore, in the present invention, a grindstone wear correction structure is adopted to improve this problem. That is, Fig. 2 is a countermeasure process diagram, in which a is the time at the start of grinding, b is when the initial workpiece is completed, c is the time when the workpiece is completed with the grindstone worn, and d is the time after the grindstone wear has been corrected. This shows the relative position of the standard gauge and distance meter. When the grinding wheel is worn and the value of L-2 becomes smaller than the required value, the moving mechanism 5-1 attached to it is first activated while reading the measured value of the distance meter 5 in the state of c when the workpiece is completed, as shown in d. The distance meter 5 is moved upward so that the distance becomes L-1, that is, the distance meter 5 is moved back from the table 1 by the amount of wear on the grindstone 3.

言うまでもない。 To explain this grindstone wear detection and correction operation in more detail, grindstone wear detection involves measuring the distance to a standard gauge with a distance meter each time a workpiece is completed, and using the initial (first) measurement value as the reference value. The amount of wear on the grindstone is detected by sequentially comparing it with subsequent measured values. Further, the position correction of the grindstone is achieved by comparing the detected amount of wear with a predetermined required value, and when the amount is less than the required value, retracting the distance meter described above. Further, the table 1 is moved upward by a distance corresponding to the wear amount of the grindstone 3, and the origin position in the feeding direction is changed from D to D'. It goes without saying that by doing this, the above-mentioned play distance is maintained at the initial state L.
