In this case, the machine tool reciprocates the work piece support means that can be attached to the machine tool to perform a reciprocating motion that repeatedly moves forward and backward with respect to the tool holding means, thereby improving the operation efficiency. You can. The workpiece support means may be mounted on the guide of the table of the machine tool. The machine tool may be provided with a drive means so that the tool holding means is rotationally driven to improve the above-mentioned work efficiency. Machine tools are
A tool in the form of a grinding wheel may be attached.

Embodiments of the apparatus according to the present invention will be described below with reference to the accompanying drawings.

Teeth 1 to 3 show a machine tool T that grinds or polishes the teeth of a circular saw 2. The circular saw machine 2 is fixed to a workpiece support means 3, which is mounted on a guide 4a of a table 4 of a machine tool T. Above the table 4 are upright pillars 9. Arranged on the upright column 9 are tool holding means having an extension arm 7 fixed to a placket 8 and a spindle support bracket 6 mounted on the free end of the arm 7. A spindle 6a is rotatably mounted within the spindle support bracket 6, and the abrasive disc 1 is mounted on the spindle 6a.

The upright 9 is vertically movable with respect to the table 4 and the arm 7 is horizontally movable with respect to the upright 9, the directions of their movement being indicated by arrows and B (see fang 2). ).

Alternatively, the upright post 9 may further be rotated about the longitudinal axis of the upright post 9 with respect to the table 4, or alternatively the clamp 8 may be rotated on the upright post 9 about its longitudinal axis. It may be rotated. As a result, the position adjustment movement of the circular saw machine 2 relative to the grinding wheel 1 can be performed completely freely.

The spindle 6a and the polishing wheel 1 are rotationally driven by conventional motor drive means (not shown), and the protector 5 surrounds a significant portion of the polishing wheel 1 as a safety measure.

The workpiece support means 3 has a fang 1 member 3a, which is slidable within the guide 4a, as described above.

On the part 3a there is a truncated cylindrical fang 2 part 3b, which can rotate on the part 3a of said fang 1 about a vertical fang axis 81. The truncated cylindrical third member 3C is the fang 2 member 3b.
The tooth 4 member 3d, which is mounted on the top and is rotatable around the f2 axis A2, and to which the workpiece 2 is fixed, is the third member 3.
It is mounted on C and is rotatable around the fang 3 axis A3. Fang 2 axis A2 is 45° with respect to axes A1 and A3
The tooth 1 axis A1 and the fan 3 axis A3 can be made coincident and can be tilted relative to each other at a desired angle of up to 90°.

By the relative movement of the fang 2 member 3b and fang 3 member 3 with respect to the fang 1 member 3a, the circular saw 2 can be positioned in any desired angular arrangement relative to the grinding wheel 1. This also applies to the indexing means 1. < can be streamlined by indexing means 11, which can be operated both manually and by control means (not shown).

After the circular saw 2 is in the desired angular position and also the grinding wheel is accurately positioned with respect to the circular saw 2, the motor drive means (
(not shown), the circular saw 2 can be reciprocated relative to the grinding wheel 2 via the gearbox 101 and the workpiece support means 3 and along the guide 4a. In this way, the polishing path is determined. When one tooth has been polished, the circular saw 2 and the tooth 4 member 3d fixing it are rotated around the tooth 3 axis A3 by an angle equal to the pitch angle of the teeth of the circular saw 2. , the above operations are repeated for all remaining teeth.

When all the teeth have been polished on one side of the circular saw machine 2, the angular arrangement of members 3b and 30 with respect to members 3a and 3b is set to an equal but opposite angular arrangement with respect to the previously set reference point. Ru. The circular saw 2 is inverted and set back in place, the grinding wheel 1 is set, and the circular saw and the grinding wheel are placed in the desired angular position so that each other on the other side of the circular saw teeth can now be polished. The above procedure is repeated for the opposite side of the circular saw 20.

In the present invention, the distribution used in the production of paper tubes and paperboard is
reverse form toothed blade
It is particularly suitable for sharpening circular saws with es), in which case the indexing direction of the saw teeth is reversed when sharpening the teeth on the opposite side of the circular saw 2'.

With the above-described configuration, the work of preparing new teeth and polishing existing teeth can be done simply, quickly and accurately.

According to the invention, the work piece (or tool) can be moved at any angle and in any position relative to the tool (or work piece) on the outside and inside of the hemisphere surface described by rotating about the center of the base. It has been found that it is possible to position the workpiece in a similar manner, and thus to carry out sequential machining of the workpiece by means of automatic equipment operably carrying a multi-pronged tool.

Figures 4 to 6 show the joint assembly structure of the members,
The assembly can be used, for example, as a work piece support member for a machine tool. The assembled structure 4o includes members 4], 42.43
and 44. The fang 1 member 41 is a base and can be fixed to a table (shown in the drawing) of a machine tool. The fang 2 member or the stand member 42 is mounted on the base 41 with the fang 1 shaft 4
It is rotatably mounted around 5. The fang 3 member or the top member 43 is the stand member 42, and the fang 1 shaft 4
It is rotatably mounted around two fang axes that are inclined at an angle of 45° with respect to 5. The spear 4 member or +Z table 44 is placed on the top member 43 with 4 points relative to the fang 2 axis 46.
It is rotatably mounted around a third axis 47 that is inclined at an angle of 5°. These three axes 45, 46, and 47 intersect at a point 48, and the intersection point is the outer surface 49 of the sima table 44.
4, which provides a reference point for a workpiece (not shown) secured to table 44 during sequential machining in any orientation.

In the illustrated state, axes 45 and 47 are coincident. When the top member 43 is rotated about the axis 46 with respect to the stand member 42, the table 44 also rotates about the axis 46, but the center of the workpiece remains at or near the reference point 48. . Such a rotation is 1
Occurring at an angle of 80°, plane 49 is vertical and axis 4
7 becomes horizontal, but the center of the workpiece still remains at or near the reference point 48, as indicated by the thick dashed line in FIG.

Such an arrangement has application in situations where a work piece mounted on the table 44 is to be reoriented with little or no displacement.

Rotation of members 42, 43 and 44 about axes 45, 46 and 47 is caused by respective motor driven shafts 50,
51.52, via a worm 53.54.55 and gear wheels 56, 57.58, the motor of the motor drive means (not shown) can be controlled by a microprocessor or computer. Shirt) 50,5
1° 52 may be manually rotated, and indexing means (not shown) may be provided to precisely rotate the appropriate member to the desired angular position relative to the base 41. It's good to be able to do it again.

In the figure, all rotation axes are in a common plane, and two axes and four
5 and 47 are overlapping, and the intermediate axis 48 is inclined at an angle of 45° to the two overlapping axes, although other arrangements can be obtained if the alignment of the parts is changed. For example, three axes lie in a common plane, two of which are orthogonal to each other, and the other axes are inclined at an angle of 45° to the two orthogonal axes.

However, it is not necessary that all axes lie in a single plane;
A configuration in which two axes intersect each other at an angle of 45° in the same plane, and the other axis intersects one axis at an angle of 45'' but is rotated 90' from the common plane of the two axes. is also useful.

The 45° tilt arrangement described herein finds use in the following situations.

For the purpose of supplying power to the motor or pulse motor, the spindles of the members 42, 43, 44 are hollow and equipped with rotary electric connectors arranged on the shafts 45, 46, 47.
cal connections) (not shown).

The present invention provides machine tools, such as cutting equipment, drilling equipment, welding equipment, etc., which require only simple forward and backward movements to perform work on one or more locations on a work piece.

This is because the workpiece itself can be moved into the desired orientation to receive the tool. This avoids the need for computer-controlled tool steering and saves equipment costs.

The main advantage of the invention is that by very simple programming of the workpiece support device, the workpiece can be correctly positioned with respect to position and orientation, so that the tool can be moved in the single direction mentioned above. Programming a tool to operate in a desired position and in a desired orientation relative to a fixed workpiece is very cumbersome and expensive; the present invention avoids this problem.

A further advantage of the present invention is that it has three axes of coincidence on the worktable surface. This involves machining on up to five sides of the cube, with the workpiece being able to be rotated relative to the tool, and placing the workpiece on its base or in a reference plane parallel to the working table, or It is even possible to create spherical objects.

INDUSTRIAL APPLICATION This invention is used for the flexible manufacturing apparatus in which the work piece holding apparatus is made into a bullet and attached to the conveyor apparatus. The workpiece is transported through a plurality of work stations, machining is performed at each of the stations, and the equipment is programmed to orient the workpiece as required to receive a respective tool at each work station.

Therefore, each tool in each work stage can simply move forward and backward without having to perform complex programmed movements. Therefore, the overall cost including equipment costs and manufacturing process costs can be reduced.

Properly orienting angled, multi-faced workpieces in various machines, especially welding equipment, to make certain faces horizontal or vertical as desired for machining or welding. That is advantageous.
