The present invention relates to a total cutter support device that is mounted on the table of the universal tool grinder to fix the cover, and then grinding the cutter blade using the abrasive stone.

In general, a cutter (hereinafter referred to as a cutter) refers to a cutter having various shapes and angles, such as a rack cutter or a spline cutter, such as a V-shape or a circular cutter, and a cutter for grinding such a cutter blade. As shown in FIG. 9, the support plate (d) is installed on one side of the front and rear moving plate (d), which is fixed to the horizontal disk (b) in which a cutter arbor (a) is arranged in the center. In the front end of the support plate (d), a fixed rod (e) is installed with a pin so that it can be rotated horizontally, but the support plate (d) and the fixed rod (e) are coalesced with a coil spring (s) to prevent the fixed rod (e) from inside. As a result, pressure is always applied.

Therefore, the cutter CT is inserted into the arbor a so that the tip end portion of the fixed interval e is inserted between the cutter CT blades seated on the upper surface of the horizontal disk b, and the inner pressure of the spuffing a is prevented. The cutter (CT) was fixed only by pressure, and then the cutter (CT) blade was ground on the abrasive stone which is installed in the universal tool grinder and rotated.

However, as described above, since the cutter CT inserted in the arbor a is fixed to the fixing rod e only by the pressing force of the spring a, the fixed state is not firm, so that the accurate division of the cutter CT is performed. There was a closed end that must be changed at all times by releasing the fixing bolt (f) fixing the supporting plate (d) to which the fixing rod (e) is attached according to the type and diameter of the cutter (CT). Due to defects such as the inability to precisely adjust and fix the angle of the cutter (CT), it is impossible to control the height of the cutter (CT), etc. As a result, abrasive wear is severe and the cutter blade is overheated due to friction with abrasive stones and burned shapes frequently occur. The density is lowered. In particular, the above phenomenon occurs frequently, so it is necessary to be very careful in the work. Therefore, it takes a lot of work time and the work efficiency per unit time is notably reduced. It has to be uneconomical and cause a decrease in workability.

The recessed portion 5 'is formed so that the curved projection 6'a at the intermediate position of the curved portion 6' formed on the lower surface of the lower angle adjustment plate 6 is inserted so that the lower angle adjustment plate 6 is supported by the support plate body 5. It is mounted on the upper surface of the slidable and the one side of the curved guide groove (5 'a) is inserted into the curved protrusion (6' a) to insert a gib (7), it can press the inserted gib (7) The lower angle adjusting plate body 6 can be fixed by screwing the fixing screw 8 to one side of the supporting plate body 5 and tightening the fixing screw 8.

In addition, a curved recess 6 "and a curved guide groove 6" a are formed on an upper surface of the lower angle control plate 6 in a direction orthogonal to the curved portion 6 'formed on the lower surface thereof, and the curved guide In the groove 6 "a, the curved protrusion 9'a at the intermediate position of the curved portion 9 'formed on the lower surface of the upper angle adjusting plate 9 is inserted so that the upper angle adjusting plate 9 is lowered. A fixing screw 8 'is mounted on one side of the curved guide groove 6 "a in which the curved protrusion 9'a is inserted into the upper surface so as to slide on the upper surface thereof. By fastening the upper angle control plate body 9 will be able to be fixed.

In addition, a bearing 10 is subtracted in the center of the upper surface of the upper angle adjusting plate 9, and an arbor 11 and a horizontal disc 12 are integrally formed with the shaft 10 of the rotating body 13. 13 ') is put in place.

The arbor 11 of the pivot body 13 is provided with a hole 11 ', and the hole 11' is fixed with a fixing plate 14 in which a nap 14 'is stored below.

In addition, the fasteners 15 and 15 'having screw holes 15a and 15'a are screwed into the upper surfaces of both sides of the upper angle adjusting plate 9, and the fixing bolts are provided to the screw holes 15a and 15'a. 16) By tightening and tightening (16 '), the fixing bolts (16) and (16') cluster are pressed against the outer periphery of the horizontal disk (12) so that the rotating body (13) can be fixed so as not to rotate.

The partition 19 is fixed to the fastener 18 fixed to the fixed plate 17 on the connecting piece 3 'integrally formed in front of the movable plate 3.

As shown in FIG. 7, the dividing table 19 is a sloping rod which is successively attached to the rear end surface of the support body 22 which is fixed to the tip end portion and supported by the hole 20 'formed in the cylindrical body 20'. (23) is screwed together to rotate the adjustment handle (24) attached to the end of the threaded rod (23) is to advance and retreat material, the spring (25) is inserted into the support 22, the fixed piece ( Since the 21 is mounted, the fixing piece 21 is always provided with an elastic force.

Reference numerals 5b and 6b are angular scales, 26 is abrasive stone, 27 is a table of a universal tool grinder, and CT is a cutter.

Hereinafter will be described the effect of the present invention.

First, the base (1) is fixed to the table 27 of the universal tool grinder (not shown), and then the cover 26 is mounted on the arbor 11 installed in the horizontal disk 12 of the rotating body 13. After fitting so as to be seated on the upper surface of the horizontal disk 12, the screw (14 ') laid on the fixing plate 14 is screwed into the hole (11') to fix the cutter (CT) flow.

Then, turn the upper and lower angle adjusting plate body (6) (9) by the set angle (θ) of the cutter (CT) blade to be ground, and then tighten the fixing screw (8) (8 ') to adjust the upper and lower angle adjusting plate body (6) (9 ). Here, only one of the angle adjusting plate bodies of the upper and lower angle adjusting plate bodies 6 and 9 can be twisted and used according to the set angle θ of the cutter CT blade.

Next, the centrifugal adjustment is performed while holding and turning the adjusting handle 24 attached to the rear end of the lower bar 23 attached to the cylindrical body 20 of the dividing table 19.

In this state, by turning and tightening the fixing bolts 16, 16 ', which are screwed to the fixtures 15, 15' on both upper surfaces of the upper angle adjusting plate 9, the horizontal disk at the tip of the fixing bolts 16, 16 '. (12) It is abutted on the outer periphery and pressed so that the rotating body 13 to which the cutter CT is fixed is fixed so that it may not rotate.

Next, loosen the fixing bolts 16 and 16 'which were fixing the horizontal disk 12 so that the rotating body 13 can rotate.

In some cases, when the cutter CT itself is heavy, the fixing bolts 16 and 15 'may be tightened to fix the bolts 16 and 16' only when the rotating body 13 cannot be rotated and divided. You can also use it by unscrewing and dividing and fixing again.

Next, the bar cutter CT, which is ground by the high-speed rotating abrasive stone 26 while moving the universal tool grinder table 27 on which the base 1 is fixed, is firmly fixed by the fixing plate 14 and is divided. (19) There is no trembling of the cutter CT by grinding the fixed piece 21 mounted on the cluster between the cutter CT blades and firmly held, thus eliminating the risk of abrasive stone breakage. .

In addition, according to the present invention, when the cutter (CT) is firmly fixed, the cutter (CT) is fixed by simply rotating the cutter (T) when the cutter (CT) blade is completely processed and then divided to process the next cutter (CT) blade. The rotating piece 13 is smoothly rotated by the bearing 10, and the fixing piece 21 mounted at the tip of the partition 19 is driven by the spring 25 installed in the support 22. In the case of being penetrated between the blades, the cutting of the cutter CT can be precisely performed since it is firmly held between the cutters 26 by the return elastic force of the spring 25.

In addition, since the angle can be adjusted according to the set angle (θ) of the cutter (CT) blade by operating the upper and lower angle adjusting plate bodies (6) and (9), the work process can be freely performed without any obstacle when performing grinding work. The time required for the grinding operation (about 1 hour) is also significantly reduced compared to the prior art.
