Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an actuator which is a kind of driving device.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 21 to 26, a linear track portion 2 and a driving portion 3 which is arranged substantially parallel to the track portion 2 and which transmits a linear motion to the track portion 2.
And an end member 4 arranged at an end portion of the track portion 2 and the drive portion 3, and the track member 2 attached to the end member 4.
An actuator 1 having a stopper 5 for stopping the moving bodies 9 and 14 of the drive unit 3 is known, and in the example shown in the figure, the track unit 2 is constituted by a linear guide 6, and the drive unit 3 is a magnetic type. Rodless cylinder 7
It is composed by.

The linear guide 6 is a linear slide rail 8 on which a slide block 9 as a moving body is reciprocally mounted, and a plate 4 as an end member is provided at each end of the slide rail 8. It is connected and fixed by a plurality of assembly bolts 10. Slide rail 8
Further, the plate 4 is provided with a plurality of through holes 11 through which mounting bolts (not shown) for mounting the actuator 1 at the mounting locations are inserted.

In the magnet type rodless cylinder 7, a piston 13 is reciprocally arranged inside a tube 12 arranged substantially parallel to a slide rail 8 of a linear guide 6, and a body as a moving body is arranged outside the tube 12. 14 are also arranged so as to be reciprocally movable, and end covers 15 are attached to both ends of the tube 12, and the end covers 15 are inserted and fixed in drive unit insertion holes 16 provided on the inner surface of the plate 4. As a result, both ends of the tube 12 are connected and fixed to the plate 4, respectively.

The piston 13 has a plurality of magnets 17
And the yokes 18 are arranged alternately in the axial direction. The body 14 is formed of a ferromagnetic material attracted to the magnet 17, and the body 14 is connected to the slide block 9 by a connecting member such as a connecting bolt 19 and a connecting pin 20. Stopper receivers 21 are provided on both end surfaces of the body 14, respectively. Each of the pair of plates 4 is provided with a port 22, and the end cover 15 is provided with a port 22 and a tube 12, respectively.
An orifice 24 for communicating the cylinder chamber 23 inside
Is provided.

The actuator 1 having the above-described structure operates to reciprocate a work (not shown) such as a machine tool mounted on the slide block 9. For example, the port 22 on the right side in FIG. When the compressed air as the working pressure is supplied from the orifice 24 to the cylinder chamber 23 in the tube 12 and the compressed air is discharged from the left orifice 24 and the port 22, the piston 13 moves to the left and is provided in the piston 13. Since the magnet 17 attracts the magnetic body 14, the body 14 and the slide block 9 connected to the body 14 move leftward. Then, when the stopper receiver 21 provided on the left end surface of the body 14 comes into contact with the stopper 5 attached to the left plate 4, the body 14 and the slide block 9 stop. On the contrary, from the state, compressed air is supplied from the port 22 and the orifice 24 on the left side to the cylinder chamber 23 in the tube 12, and the orifice 24 and the port 2 on the right side are supplied.
When the compressed air is discharged from 2, the piston 13 moves to the right, and the body 14 and the slide block 9 follow to the right. Then, when the stopper receiver 21 provided on the right end surface of the body 14 comes into contact with the stopper 5 attached to the plate 4 on the right side, the body 14 and the slide block 9 stop.

In the actuator 1 having the above-mentioned structure, the stopper 5 attached to the plate 4 has an important function to specify the stop position of the body 14 and the slide block 9 and thus the stop position of the work. Further, the stopper 5 is generally threaded on the outer peripheral surface thereof and screwed into the plate 4, and when the stopper 5 is rotated, the stopper 5 can be freely moved in the cylinder axis direction, so that the body 14 and the slide can be slid. It is configured so that the stop position of the block 9 can be adjusted. After adjusting the stop position, the nut 25 is tightened and fixed at that position.

By the way, since the rodless cylinder 7 constituting the drive unit 3 has a sliding portion, it is necessary to appropriately perform maintenance. Specifically, the grease of the cylinder portion is deteriorated, the piston seal, Since wear parts, such as wear rings, bushes, and dust seals, may be worn, it is necessary to fill them with grease or replace piston seals with new ones at a certain time.

In carrying out this maintenance, in the above-mentioned prior art, it is necessary to loosen the assembly bolt 10 and remove the plate 4 from the ends of the slide rail 8 and the tube 12, but this has the following problems. .

That is, in the above-mentioned prior art, the stopper 5 attached to the plate 4 as described above has an important function of specifying the stop positions of the body 14 and the slide block 9. Although the stop positions of the body 14 and the slide block 9 are predetermined as numerical values on the drawing, in the actual device, the entire device is assembled due to the tolerances of each part and the work, variations in assembly, and the like. After that, while actually operating the cylinder 7, the position of the stopper 5 is finely adjusted to adjust the actual product.

On the other hand, in order to connect the plate 4 to the slide rail 8, the slide rail 8 is provided with a screw hole 26, and the plate 4 has a hole or a through hole 27 into which the assembly bolt 10 to be screwed into the screw hole 26 is inserted. Since the inner diameter of the through hole 27 of the latter plate 4 is set to be larger than the outer diameter of the assembly bolt 10, the dimension between the inner surface of the through hole 27 and the bolt 10 is set. There is a difference gap.

Therefore, when performing maintenance, the assembly bolt 10 is loosened, and the plate 4 with the stopper 5 attached thereto is once removed from the slide rail 8. When the plate 4 is reassembled, the position of the plate 4 is moved in the axial direction by the above-mentioned clearance. And accordingly, the position of the stopper 5 attached to the plate 4 also shifts in the axial direction by the amount of the above-mentioned gap, so that the stop positions of the body 14 and the slide block 9 at the time of operation are also shifted by this amount. It will be displaced. In today's devices requiring high-precision operation, the stop position accuracy of the drive unit 3 such as the rodless cylinder 7 is often adjusted in units of 1/1000 mm, and even a slight deviation is not allowed. When the position of is shifted, it takes a lot of time and effort to perform the position adjustment again.

Even if a positioning pin is provided between the slide rail 8 and the plate 4, it is necessary to make the plate 4 detachable from the slide rail 8 for the above maintenance. It is necessary to provide a clearance with the hole of the plate 4 into which the pin is inserted, and the position of the stopper 5 will be displaced by this clearance after reassembly. Therefore, as described above, 1/1000 mm
It is not suitable for devices that require unit stop position accuracy.

When the plate 4 is formed of aluminum alloy or the like in order to reduce the weight of the actuator 1, iron or stainless steel pins may be inserted into and removed from the holes of the plate 4 many times each time the above maintenance is performed. Therefore, wear and deformation occur in the holes of the plate 4. Therefore, the clearance between the pin and the hole is gradually increased, and the positional accuracy of the stopper 5 is further deviated.

Further, in the above-mentioned prior art, when the plate 4 is removed from the slide rail 8 and the tube 12, the slide block 9 and the body 14 may fall off from the slide rail 8 and the tube 12. In the linear guide 6, the rolling resistance of the slide block 9 moving on the slide rail 8 is extremely small, so that the slide block 9 easily moves on the slide rail 8 even with a slight force. Therefore, when performing maintenance with the plate 4 removed, the slide block 9 may slip on the slide rail 8 and fall off due to an unexpected trouble. If the slide block 9 falls off, the slide block 9, the body 14, peripheral devices or workpieces may be removed. Damaged or
There is a risk of injury to workers.
