た。(Prior Art) This type of automatic grinding wheel cover correction device for a grinding machine has a grinding wheel head, a grinding wheel pivotally supported by the grinding wheel head, and a grinding wheel cover that covers at least the upper front half of the grinding wheel. The grinding wheel is supported on the grinding wheel head so as to be movable in a direction orthogonal to the rotational axis of the grinding wheel, and the grinding wheel cover is moved in the orthogonal direction in response to a decrease in the diameter of the grinding wheel due to modification of the grinding wheel. The gap between the tip of the cover and the outer periphery of the grinding wheel is kept within a predetermined range, but the conventional one uses a servo motor on the grinding wheel head side, as shown in JP-A-52-131295, for example. A screw shaft driven by this is provided, and the screw shaft is screwed into a nut on the grindstone cover side.
Each time the radius of the grinding wheel was adjusted, the servo motor was used to move the grinding wheel cover little by little to correct the gap between it and the grinding wheel. However, since this requires a servo motor, a screw shaft, a nut, and other supporting members, the structure becomes complicated, which is an obstacle to reducing manufacturing costs. On the other hand, there are devices in which the screw shaft is rotated by a ratchet wheel device instead of a servo motor, but the above-mentioned problem has not been solved.

As shown in the figure, a restraint mechanism 40 is provided to prevent the grindstone cover 13 and the movable plate 31 from moving unnecessarily when the movable claw 35 rides on the riding plate 38 and is disengaged from the engagement teeth 31b. The restraint mechanism 40 uses a spring 43 to press downwardly a restraint member 42 supported by a pivot shaft 44 on an upper plate 41, and engages engagement teeth 42a on the lower surface of the restraint member 42 with an engaging pawl 45 fixed to the movable plate 31, so that the movable plate 31 restrains the forward movement of the Thereby, when the grinding wheel 11 is damaged, it is possible to prevent the grinding wheel cover 13 from being moved forward by the damaged grinding wheel.

車半径Roを予め記憶装置61に与えておく。 The control device 60 performs the processing shown in FIGS. 3 to 5. First, the grindstone correction process shown in FIG. 3 and the grindstone cover movement process shown in FIG. 4 will be explained. The control device 60 in FIG. 1 operates the grinding wheel shaping correction device 20 to perform grinding wheel correction processing every time a certain number of workpieces W are processed. That is, as shown in FIG.
The grinding wheel 11 is cut by an amount of cut U more than the previous time, the grinding wheel 11 is corrected by traverse movement, the correction tool 24 is then moved backward, and the grinding wheel head 10 is moved forward by the corrected depth of cut U. At the same time, the radius R of the grinding wheel 11 before correction read from the storage device 61 is subtracted by the depth of cut U to obtain the radius R after correction, and this is stored in the storage device 61 to memorize the radius R of the grinding wheel 11. Update the value. Following the above grinding wheel correction process, the fourth
Although the grindstone cover moving process shown in the figure is performed, this does not mean that the ratchet mechanism 30 is operated to move the grindstone cover 13 every time the grindstone wheel 11 is corrected. Every time the radius R of the grinding wheel 11 decreases by 10 mm, the grinding wheel cover 13 is moved back by one pitch, that is, by 10 mm. Based on the initial grinding wheel radius Ro
Value B set every 10 mm and radius R of grinding wheel 11
is read by the storage device 61, B and R are compared, and the control device 60 starts the grindstone only once, immediately after the radius R passes the set value B (at this time, the set value B is updated to B-10). A cover movement signal is generated, and the ratchet mechanism 30 is operated via the interface 63, the switching valve 51, and the cylinder device 50 to move the grindstone cover 13 back by 10 mm. When the set value B is updated successively and becomes less than the final grinding wheel radius Rmin, which is the usage limit of the grinding wheel 11, the grinding wheel 11 is replaced. Before operating the grinding machine after replacing the grinding wheel, the initial grinding wheel radius Ro is previously given to the storage device 61.

生するようにした。 In the illustrated embodiment, corrective tool wear correction is performed, so the control device 60 performs the process shown in FIG. 5 every time it receives a sizing signal from the sizing device 64, The stored value of radius R of No. 11 is updated every time machining is performed. As shown in FIG. 5, for each machining process, the position counter value P (indicated by the diameter of the workpiece) of the grindstone head 10 is read out, and the finishing diameter D of the workpiece W stored in advance in the storage device 61 is read out. The difference ε (=D−P) between the two is obtained.
Since the difference ε is mainly the wear amount of the correction tool 24, the difference ε is added to the radius R of the grinding wheel 11 to correct it.
Update the stored value of radius R. Further, the position counter value P is updated to be equal to D and stored, and the position counter P is corrected. In this embodiment, the stored value R of the radius of the grinding wheel 11, which is stored in the storage device 61 while being updated sequentially, does not simply decrease with the number of times the workpiece W is processed, as shown in FIG. While repeating increases and decreases, it gradually decreases as a whole. Therefore, one of the set values B, which is set while updating every 10 mm, is set multiple times during the decreasing process (in Fig. 6, P
1, p2, and p3), it is necessary for the control device 60 to generate the grindstone cover movement signal only during the first pass (p1 in FIG. 6). For this purpose, the section between the set value B and the value A 10 mm before it (= B + 10) is r
The parameter N is divided into areas r1, r2, r3, and r4, and as shown in FIG.
is increased by 1 step each time the grinding wheel is corrected,
In area r3, parameter N is set to 0,
Parameter N is kept unchanged in zone r4, and a grindstone cover movement signal is generated only when the value of parameter N changes from 0 to 1 outside zone r4.

By retreating using a ratchet mechanism, the grindstone cover 13 may be rotated to maintain a gap with the outer periphery of the grindstone within a predetermined range. Although the ratchet mechanism 30 is operated by the cylinder device 50 using fluid pressure, it may be operated by an electromagnetic or other actuator.

都度ではなく、砥石車11の半径Rが一定量減少
する毎に行うことにより解決され特に問題となる
ことはない。(Effects of Example) In the above example, the driving side of the direct-acting ratchet mechanism 30 is directly attached to the grindstone guard 12, and the driven side is directly attached to the grindstone cover 13, so there is no need for a power transmission means such as a screw shaft. Therefore, its mechanical configuration can be greatly simplified and manufacturing costs can be reduced. The increase in the amount of movement of the grinding wheel cover 13 by using the direct-acting ratchet mechanism 30 means that the movement of the grinding wheel cover 13 is not made every time the grinding wheel 11 is corrected, but by a fixed amount of the radius R of the grinding wheel 11. This can be solved by doing this every time the number decreases, and there is no particular problem.
