The present invention relates to a simultaneous three-axis control device of a general-purpose tool grinder, and more particularly, by improving the structure of a low-cost general-purpose tool grinder to control the tool in three axes at the same time with only one handle operation, The present invention relates to a simultaneous three-axis control device for a general-purpose tool grinder, which reduces the manufacturing cost and improves productivity by enabling the grinding of curved surfaces of a tool, especially a step drill, in a step drill at once, which is possible even in an expensive CNC machine.

In general, a general-purpose tool grinder is to grind a tool blade when the tool is mounted on the machine and the blade is worn or before a new tool is mounted on the machine.

In other words, the drill used in the punching operation wears out the cutting edge of the tip part after a certain period of time, and thus the cutting efficiency is reduced.

The conventional general-purpose tool grinder 1 is, as shown in Fig. 1a and 1b, the first base 20 and the front and rear, which are installed to be transported in the left and right (X-axis) direction, respectively, on the upper end of the main body 10 The 2nd base 30 provided so that a transfer to a (Y-axis) direction is provided, and the grinder 35 is installed in the upper end of the said 2nd base 30 so that a lifting-down is possible.

The first and second bases 20 and 30 are transferred to the X-axis and the Y-axis by the pivoting operation of the handles 21 and 31, respectively, and the grinding machine 35 also rises by the pivoting operation of the handle 32. Will descend.

In addition, a table 25 is coupled to the first base 20, and a tool fixing means 40 is installed on the table 25. The tool fixing means 40 has a work head 41 coupled to the upper end of the table 25, a spindle 42 rotatably coupled to the work head 41 and one end of the spindle 42 It is composed of a chuck adapter 43 coupled.

The tailstock 50 may be further installed at a position spaced apart from the workhead 41 so as to support the end portion center of the tool.

Various chucks (collet chuck, lathe chuck, both center chucks, etc.) 44 are selectively detachably coupled to the chuck adapter 43 to fix the tool.

On the other hand, the chuck adapter 43 is provided with a dividing plate 45, the upper end of the work head 41 is provided with a dividing table 46 for fixing the dividing plate 45 at a predetermined position. Therefore, after the tool is fixed using the chuck 44 and the tail stock 50, the position of the partition plate 45 is fixed by the partition 46 to adjust the initial machining position of the tool.

In this manner, after the tool is fixed, the tool rotates the handles 21 and 31 to transfer the first and second bases 20 and 30 in the X and Y axis directions so that the tool is a grinding wheel of the grinding machine 35. It comes into contact with 36 and grinding is performed.

The universal tool grinder 1 performs the grinding operation by individually operating the first base 20 for conveying the tool which is not rotated in the X-axis direction and the second base 30 for feeding in the Y-axis direction, respectively. Because of this, only a simple planar operation is possible, which limits the grinding of various tools.

That is, the step drill 5 as shown in Figure 2a is used to process holes having various diameters or to process the chamfer (chamfer) of the hole inlet by varying the diameter of the drill step by step, this step drill (5) also for a certain time When used, the step edges 5a and 5b are abraded and the cutting efficiency is lowered. Therefore, the step edges 5a and 5b must be ground and reused.

Therefore, in order to process the step blades 5a and 5b of the step drill 5, the step blade 5a is used as shown in Fig. 2A using an expensive machine capable of simultaneously controlling multiple axes such as a CNC. The step edge 5b was ground several times in a planar shape as shown in FIG. 2B using the grinding | polishing at once by the curved surface, or using the low cost universal tool grinder 1.

However, when using equipment such as CNC, there is a problem of purchasing expensive equipment. When using a low-cost general-purpose tool grinder 1, the step drill 5b cannot be processed at once, so the step drill 5 Since the step edge (5b) to be grinding while changing the position of the several times, the productivity is reduced, as well as the problem of increasing the defective rate in the process of grinding several times.

An object of the present invention for solving the above-mentioned problems is to improve the structure of a low-cost general-purpose tool grinder so that the tool is controlled in three axes at the same time with only one handle operation, so that even in a low-cost general-purpose tool grinder, It is possible to provide a simultaneous three-axis control device for a general-purpose tool grinder that reduces the manufacturing cost and improves the productivity by enabling the curved grinding of the tool, especially the step blade of the step drill, at once.

The present invention for achieving the above object is installed on the main body and the upper end of the main body and the first base and the front and rear (Y-axis) to be transported in the left and right (X-axis) direction, respectively. And a table having a second base having a grinding machine at the top and a tool fixing means having a chuck adapter and a spindle so as to be rotatably fixed to the top of the first base. In the grinding machine, the cam shaft is rotatably installed on the support block coupled to the upper portion of the table, and the spindle is connected to the spindle by means of a rotational force transmitting means, and is provided between the table and the first base. And an intermediate table slidably coupled to the first base, respectively, and coupled to one end of the table, wherein an upper side is an outer circumferential surface of the cam. A first movement switching means for contacting the lower side and being in contact with the intermediate table to convert the rotational movement of the cam into a linear movement of the table, and between the table and the first base to intermediate the linear movement of the table. It comprises a second movement switching means for switching to the linear movement of the table, but in a direction perpendicular to the direction of movement of the table, and the table and the intermediate table in the X, Y axis direction at the same time as the spindle rotates when the cam shaft is rotated It characterized in that the tool fixed to the tool holding means to be controlled in three axes at the same time by linear motion.

On the other hand, when the grinding work while supporting the center of both ends of the step drill (5), the step drill (5) is bitten by both center chuck 154, at this time, the grinding wheel during the grinding operation on both center chuck (154) The rotation prevention structure 157 is provided so that the step drill 5 may not rotate by 162. Since both center chuck 154, as well as the anti-rotation structure 157 is well known, a detailed description thereof will be omitted.

Hereinafter, the operation of the simultaneous three-axis control device 100 of the general-purpose tool grinder according to the present invention will be described. In addition, although various tools can be ground, the case where the step edge 5a of the step drill 5 is ground for convenience is demonstrated as an example.

First, the step drill 5 for grinding is fixed using the chuck 154 and the tail stock 170, and when the fixing is completed, the handles 121, 131, and 161 are rotated to operate the first, 2, the base 120 and 130 are moved in the X and Y axis directions so that the grinding wheel 162 of the grinding machine 160 is close to the step edge 5a of the step drill 5.

Thereafter, when the operator rotates the handle 213 of the cam shaft 210, the step drill 5 is simultaneously controlled in three axes so that the step blade 5a is ground at a time. That is, the spindle 152 rotates at the same time as the cam shaft 210 rotates, the table 140 linearly moves in the X-axis direction, and the intermediate table 200 linearly moves in the Y-axis direction so that the step drill 5 is performed. At the same time, it is controlled in the three axis direction.

This will be described in more detail as follows.

First, when the cam shaft 210 is rotated, the drive gear 221 and the cam 211 provided on the cam shaft 210 is rotated together, at this time driven gear connected to the drive gear 221 and the timing belt 223. The step drill 5 fixed to the chuck 154 rotates by rotating the spindle 152 while the 222 rotates at a constant rotation ratio.

Subsequently, when the cam 211 rotates, the lifting shaft 232 of the first movement switching means 230 which is always in contact with the outer circumferential surface of the cam 211 is raised and lowered, and the lifting shaft 232 is lowered. In this case, the inclined surface 232b of the lifting shaft 232 is in sliding contact with the roller 201 of the intermediate table 200, and in this process, the table 140 is linearly moved in the X-axis direction.

When the table 140 is linearly moved in the X-axis direction, the second guide 242 coupled to the table 140 moves together in the X-axis direction, where the inclined surface 242a of the second guide 242 is moved. The first guide 241 coupled to the upper end of the first base 120 is in sliding contact, and in this process, the intermediate table 200 is linearly moved in the Y-axis direction.

As such, the operator rotates the camshaft 210 and at the same time the spindle 152 rotates and the table 140 and the intermediate table 200 are linearly moved in the X and Y-axis directions, thereby being fixed to the chuck 154. The step drill 5 is controlled in the three axis direction at the same time.

On the other hand, when there are two step blades 5a of the step drill 5, the operator rotates the camshaft 210 two times, and at this time, the spindle 152 rotates one time and is formed on the circumference of the step drill 5. Two step blades 5a are ground to a curved surface at one time.

Here, the reason for rotating the cam shaft 210 in proportion to the number of the step blade (5a) is, if the cam shaft 210 is rotated once, the cam 211 formed on the cam shaft 210 also rotates by one, at this time cam When the 211 is rotated once, the table 140 and the intermediate table 200 are linearly reciprocated once in the X and Y axis directions, respectively, and one step blade 5a is ground to the curved surface.

Therefore, the cam shaft 210 should be rotated two times in the case of two of the step blades 5a, and the cam shaft 210 should be rotated three times in the case of three step blades 5a. Of course, at this time, the spindle 152 and the tool (step drill) should be only one revolution.

On the other hand, when the table 140 and the intermediate table 200 are moved to the maximum distance in the X, Y axis direction by the rotation of the cam 211, and then restored to the initial position again, the table restoring means 260 and the middle It is elastically restored by the table restoration means 261.

As described above, in the present invention, only the grinding of the step edge 5a of the step drill 5 for the sake of convenience is described. However, the present invention is not limited thereto, and any tool that requires curved grinding can be ground. .

In addition, the present invention, as well as curved grinding through the three-axis control device 100 at the same time, all the operations that can be performed in the conventional universal tool grinding machine is possible.

According to the present invention, by improving the structure of the low-cost general-purpose tool grinder to control the tool in three axes at the same time with only one handle operation, the surface grinding of the tool is possible, especially in expensive CNC, etc. The step edge of the step drill can be ground at one time, reducing manufacturing costs and increasing productivity.
