Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION A linear motor for generating a thrust between a stator and a moving member is mounted on a table device such as a machine tool, and a moving member (table or saddle) of the table device is fixed on the fixed member (saddle or saddle). The present invention relates to an assembling apparatus and an assembling method for a linear motor that can be attached and detached while being attached to a bed.

[0002]

2. Description of the Related Art Recently, table devices such as machine tools, measuring machines, and various positioning tables have been controlled for axis feed by linear motors, and have been applied to conventional axis feed devices using ball screws and rotary servomotors. Compared to this, the axis feed can be servoed with much higher responsiveness, higher speed and higher accuracy. In particular, in the electric discharge machine, it is important to appropriately control the minute electric discharge gap between the tool electrode and the workpiece in accordance with the machining state in order to efficiently perform the machining with high accuracy. In the axis feeder consisting of a ball screw and a rotary servomotor, the response of the axis feed control according to the feedback signal that detects the discharge state is poor and delays cannot be avoided. The limit was being seen in the conversion. Under these circumstances, the adoption of a linear motor for axis feed
The discharge gap can be controlled with a high response in accordance with the discharge state, and the electric discharge machining can be performed at a high speed exceeding the conventional limit.

[0003]

On the other hand, in order to use the linear motor for the axial movement of the table as described above, when the linear motor is mounted on the table device, the magnet row side (usually a moving element) of the linear motor and the coil are used. It is necessary to assemble such that the gap (air gap) between the iron core row side (usually the stator) around which is wound is a gap of a predetermined size, and each of the movable element and the stator is attached to a table device (bed or saddle). Or, when assembling directly to a table, a small predetermined gap of several tens to several hundreds μm is formed by assembling and assembling members manufactured in advance with dimensional control.

Further, a magnetic attraction force approximately 10 times the rated thrust of the linear motor acts between the stator and the moving member of the linear motor when they are in close contact with each other. Also, a large force is required to separate them, and if they are forcibly separated, the opposing surfaces of both may be damaged. Care must be taken to prevent this from happening, and as described above, careful attention is required because the gap between the two is very small.

[0005] Further, when an accident such as burning of a coil or biting of a foreign substance occurs during operation of such a linear motor-driven shaft feeder, it becomes necessary to replace the linear motor. If it is necessary to remove the saddle or the saddle, a complicated operation for adjusting the straightness of the axis feed movement after the table and the saddle are assembled is required. Therefore, for example, a magnet row constituting a long moving element of a linear motor is divided and attached, and when replacing the linear motor, the table or saddle is moved to the moving end and the magnet row on one side is replaced. At a position not facing the coil side (stator), remove the magnet row at this position, and then move the table or saddle to the opposite moving end,
The magnet row on the other side is located at a position not facing the coil side, the magnet row is removed, and finally the coil side (stator)
Is removed, the linear motor can be replaced without removing the table or saddle and without magnetically attracting the moving element and the stator. However, when the magnet array is divided into two plates, care must be taken in assembling the two plates so as not to impair the mounting pitch accuracy of the magnet arrays. In addition, since the work of attaching and detaching the bolts near the connecting portion of the two plates is not easy because the work is performed in a relatively narrow space between the movable side member and the fixed side member, it is preferable that the magnet row is not divided into two.

In the case of this type of synchronous machine type linear motor, the length of each of the magnet rows and the coil in the direction of movement is determined by a movement stroke mainly required by the former and a thrust mainly required by the latter. Therefore, in many cases, the length of the magnet array is shorter than about twice the length of the coil side. Therefore, in such a case, if the movement stroke of the saddle and the table is increased, the magnet row can be positioned and removed at a position not opposed to the coil side, but the mechanical device is unnecessarily increased in size. I will.
Further, it is necessary to avoid increasing the moving stroke by using a magnet row longer than the necessary stroke for replacing the linear motor, because it is large and wasteful.

In view of the above problems, the present invention is directed to a linear device, which has a fixed side member and a movable side member of a table device such as a machine tool, even if the movable side member has a small moving stroke. A linear motor that can be easily attached to and detached from the moving-side member and the fixed-side member in a state where a predetermined air gap is formed between the moving member and the stator of the motor without causing magnetic attraction. It is an object to provide an assembling apparatus and an assembling method.

And a stator mounting base fixing member for connecting and fixing the stator mounting base and the fixed side member.

It is characterized by being interposed.

According to a third aspect of the present invention, a rolling spacer is used in place of the roller and the rail-shaped spacer in the first aspect.

Both contact surfaces are polished smoothly so as to make it slippery. When the rail-shaped spacer 5 is placed on the mounting seat 4b and the moving element mounting base 2 and the stator mounting base 4 are overlapped, the roller 2b is located on the rail-shaped spacer 5 and the base 2 can move in the longitudinal direction. At this time, the height of the rail-shaped spacer 5 is formed so that an air gap G having a predetermined size is formed between the moving element 1 and the stator 3.

A linear motor assembling device is configured, and the two bases 2 are interposed with the rail-shaped spacer 5 interposed therebetween.
The height (thickness) of the linear motor unit formed by superimposing the base 4 and the base 4 is such that the base 2 mounting surface on the lower surface of the saddle and the base 4 mounting on the bed in a state where the saddle and the table are assembled on the bed in a predetermined manner. It is formed slightly smaller than the space between the surfaces or the space between the base 2 mounting surface on the table lower surface and the base 4 mounting surface on the saddle upper surface. The moving member mounting base 2, the stator mounting base 4, the stator mounting base fixing member 6, and other supporting members of the roller 2b, the stator supporting member 3a, and the like are not deformed by the strong magnetic attraction that acts. In addition, the section modulus is sufficiently large,
Has high rigidity.

The procedure of an embodiment of the method of the present invention for assembling a linear motor to a machine tool or the like in a state where a saddle and a table are already assembled on a bed using the assembling apparatus of the present invention configured as described above will be described. This will be described with reference to FIGS. Here, the case of attaching between the bed and the saddle will be described, but the same applies to the case of attaching between the saddle and the table.

When mounting a linear motor, first,
After the mover 1 is fixed to the mover mounting base 2 and the stator 3 is fixed to the stator mount base 4, the mounting seat 4b of the base 4 is fixed.
The base 2 is placed on the base 4 with the rail-shaped spacer 5 placed thereon. Then, the core row of the stator 3 is attracted by the magnet row of the mover 1 and the two bases 2 and 4 are attracted to each other, and the roller 2b rolls on the rail-shaped spacer 5 so that the gap between the magnet row and the core row is formed. The base 2 moves to the position where the suction force of the base 2 acts most strongly.
The two bases 2 and 4 are not relatively displaced by a slight force. At this time, mover 1 and stator 3
An air gap G having a predetermined gap size is formed between them. The linear motor unit 7 in which the two bases 2 and 4 are integrally assembled by strongly attracting by the magnetic attraction force is pressed against the end face of the stator mounting base 4 by the pushing jig 8 so that the XY 2 Insert in any one of the shaft directions (FIG. 5).

Next, the slider mounting base 2 is
The linear motor unit 7 is pushed in until it is located at a predetermined mounting position on the lower surface of the. At this time, it is desirable to provide a positioning stopper 11 so that the pushing position can be easily determined. In this state, since the thickness of the linear motor unit 7 is formed to be slightly smaller than the gap between the lower surface of the saddle 10 and the bed 9, a slight gap is formed between the base 2 and the lower surface of the saddle 10. (FIG. 6).

Then, at this position, the movable member mounting base 2 is fastened and fixed to the lower surface of the saddle 10 by bolts 2c using the mounting holes 2a. At this time, the bolts 2c are tightened substantially equally. As the bolts 2c are tightened, the entire linear motor unit 7 rises, and the stator mounting base 4
A slight gap is formed between the bed and the bed 9. The gap between the moving element 1 and the stator 3 is maintained at a predetermined air gap G (FIG. 7).

Next, one fixing member 6 of the two L-shaped stator mounting base fixing members 6 is temporarily fixed to a predetermined position on the bed by using bolts 6c using mounting holes 6b. At this time, if the fixing member 6 and the stator mounting base 4 interfere with each other, the saddle 10 is slightly moved to move the base 4 to a position where there is no interference, and the fixing member 6 is temporarily fixed. Then, if necessary, the saddle 10 is slightly moved so that the end surface of the base 4 is in contact with the temporarily fixed fixing member 6, and the other fixing member 6 is in contact with the end surface of the base 4. 6 is temporarily fixed to a predetermined position on the bed with bolts 6c. Thus, the stator mounting base 4 is sandwiched by the two fixing members 6 (FIG. 8).

Next, the bolts 6d inserted from the respective mounting holes 6a of the two fixing members 6 are screwed into the screw holes 4c of the stator mounting base 4 to fix the fixing member 6 to the base 4. At this time, the dimensions are controlled so that the screw hole 4c and the mounting hole 6a are concentric. The gap between the moving element 1 and the stator 3 is maintained at a predetermined air gap G. After fixing the two fixing members 6 to the base 4 respectively, the temporarily fixed bolts 6c are fully tightened to fix the two fixing members 6 to the bed 9 (FIG. 9).

Finally, the rail-shaped spacer 5 is pulled out, and the work of mounting the linear motor is completed. At this time, the spacers 5 are arranged so that the rail-shaped spacers 5 are slippery.
Since the contact surfaces of the mounting seat 4b and the mounting seat 4b are polished smoothly, it can be pulled out (FIG. 10). In this way, with the saddle 10 mounted on the bed 9, the linear motor is magnetically attracted to the movable element and the stator with a predetermined air gap G formed between the movable element and the stator. It can be easily mounted without fear.

When the linear motor is to be removed, the procedure is reversed from that for mounting. First, the roller 2b and the mounting seat 4
After the rail-shaped spacer 5 is inserted between the fixed members 6b, the bolt 6d fixing the fixing member 6 to the stator mounting base 4 is removed, and the bolt 6 fixing the fixing member 6 to the bed 9 is removed.
Remove c, and remove the two fixing members 6. Since the rail-shaped spacer 5 is interposed between the moving member mounting base 2 and the stator mounting base 4, there is no possibility that the two bases 2 and 4 are magnetically attracted. Next, the bolts 2c that fix the movable member mounting base 2 to the back surface of the saddle 10 are loosened and removed substantially evenly,
The linear motor unit 7 is mounted on the bed 9. Finally, the linear motor unit 7 is pulled out of the space between the bed 9 and the saddle 10, and the work of removing the linear motor is completed.

In a case where the rail-shaped spacer 5 is difficult to be inserted between the roller 2b and the mounting seat 4b in the above-mentioned removal work of the linear motor, a push bolt is attached to one of the bases 2 and 4. May be provided on the other base. If you do that,
By pushing in the push bolt, the space between the two bases 2 and 4 is widened, and the rail-shaped spacer 5 can be easily inserted. If necessary, the rail-shaped spacers 5 may be used when the rail-shaped spacers 5 are pulled out in the mounting operation.
After the rail-shaped spacer 5 is pulled out,
Or, after insertion, it is returned to the original position.

Here, a state in which a linear motor is mounted by using the assembling apparatus and the assembling method of the present invention is described as an example of a table apparatus such as a machine tool by using an XY of an electric discharge machine.
This will be described by taking a table device as an example. As shown in FIG. 11, a saddle 10 is mounted on a bed 9 via a cross roller bearing 12 so as to be movable in the Y-axis direction.
A table 14 is mounted on the upper side via a cross roller bearing 13 so as to be movable in the X-axis direction, and a linear motor is provided in a space between the bed 9 and the saddle 10 so that the moving direction is parallel to the Y-axis. The linear motor is mounted in the space between the table 10 and the table 14 in the above-described manner so that the moving direction is parallel to the X-axis, and the table 14 is controlled to be fed in the X-axis and Y-axis directions with respect to the bed. Usually, a processing table is provided on the table 14, and a workpiece is mounted and fixed on the processing table to perform electric discharge machining.

As in the above-described embodiment, usually, the iron core row side (coil side) is fixed to the fixed side member as a stator, and the magnet row side is fixed to the moving side member as a mover. That is,
In the X-axis drive device between the table 14 and the saddle 10, the coil side is fixed to the saddle 10, the magnet row side is fixed to the table 14, and the Y-axis between the saddle 10 and the bed 9 is fixed.
In the shaft driving device, the coil side is fixed to the bed 9,
The magnet row side is fixed to the saddle 10. Conversely, the coil side may be the mover and the magnet row side may be the stator,
It is preferable that the coil side be a stator.

FIG. 1 shows another embodiment of the assembling apparatus according to the present invention.
This will be described with reference to FIGS. In the linear motor unit 7 shown in FIG. 12, a roller 2b is provided on the movable member mounting base 2, and a plurality of rollers 4d are also provided on both side surfaces of the stator mounting base 4, and the rail-shaped spacer 5 is connected to the rollers 2a and 4d. This embodiment differs from the above-described embodiment in that it is interposed between them. With this configuration, the rail-shaped spacer 5 can be easily pulled out and inserted.

The linear motor unit 7 shown in FIG.
Both sides of the lower surface of the slider mounting base 2 and the stator mounting base 4
Rolling seat 2 on which rollers roll on each side edge of the upper surface
d, 4e, and between the upper and lower rolling seats 2d, 4e,
As shown in the perspective view of FIG. 15, a rolling spacer 15 provided with a plurality of rollers 15b on the side surface of a long plate 15a is interposed. Also, instead of the rolling spacer 15 between the two rolling seats, as shown in a perspective view in FIG. 16, a bearing row plate 16b on which a large number of needle bearings 16a are rowed is arranged from above and below plates 16c and 16d. It may be configured to interpose the flat bearing 16 sandwiched between the two. Either the rolling spacer 15 or the flat bearing 16 can be easily removed when the linear motor is mounted and inserted when the linear motor is removed. In this case, if the two bases 2 and 4 are moved relative to each other, the extraction and insertion operations can be performed more easily. In the flat bearing 16, the plate 1
It is also possible to omit the 6c and 16d and to interpose the bearing row plate 16b between the two smooth surfaces.

In the case of a large linear motor for a large machine tool, as shown in FIG. 14, the linear motor unit 7 is connected to the lower side edges of the moving member mounting base 2 and the upper surface of the stator mounting base 4. A linear motion bearing 17 composed of a bearing block 17a and a guide rail 17b may be assembled between both side edges in parallel with the moving shaft. In this case, after the linear motor is attached, the linear motion bearing 17 is used without being removed without being removed. With this configuration, a strong magnetic attraction force acting between the moving element 1 and the stator 3 is borne by the linear motion bearing 17, and the magnetic attraction force borne by the fixed member and the moving member is reduced. Saddle 10
Also, since the possibility of deformation of the table 14 due to the magnetic attraction force is reduced, the saddle 10 and the table 14 can be made lightweight.

In the case of a large-sized linear motor, the linear motor unit can be inserted or removed with a small pushing or pulling force between the stationary member and the stator mounting base 4. The flat bearing 16 may be interposed. In this case, when the linear motor is attached, the moving member is moved as necessary to remove the flat bearing 16, and when the linear motor is removed, the moving member is moved as necessary to fix the flat bearing 16 to the fixed side. Work is performed by arranging it on a member.

In the method of the present invention shown in FIGS. 5 to 10, when the linear motor is mounted, the rail-shaped spacer 5 is finally pulled out and removed. If you do this,
Although the two bases 2 and 4 can be moved in a free state without mechanical contact between the slider mounting base 2 and the stator mounting base 4, the slider mounting base 2 can be moved even if the rail-shaped spacer 5 is provided. Since it is movable by the rolling of the roller 2b, the rail-shaped spacer 5 does not necessarily have to be removed when the linear motor is attached. However, when the rail-shaped spacer 5 is used while being installed, it is necessary to fix the spacer 5 to the stator mounting base 4 by bolting or the like so that the spacer 5 is not displaced by the operation of the linear motor.

[0033]

As described above, according to the present invention, the moving member mounting base for fixing and holding the moving member and the stator mounting base for fixing and holding the stator are provided between the base and the rollers and the rail-shaped spacers. By stacking the moving element mounting base on the upper side with a rolling spacer or linear motion bearing interposed, the two bases are attracted and integrated by magnetic attraction with an air gap of a predetermined size formed between the moving element and stator. A linear motor unit is formed, and the linear motor unit is pushed into the space between the movable side member and the fixed side member from the side to fix the movable member mounting base to the movable side member. By fixing to the stator mounting base and the fixed side member and connecting and fixing the stator mounting base to the fixed side member, the moving side is fixed to the fixed side member of various table devices. Even if the moving stroke of the moving member is small while the material is still assembled, an air gap of a predetermined size is formed between the moving element and the stator of the linear motor, and the air gap is always secured to magnetically The moving element can be easily attached to and detached from the moving-side member and the stator can be easily attached to and detached from the fixed-side member without being attracted.
