After inserting several pins 35..., the workpiece 17a is clamped with two intersecting sides of the workpiece 17a in contact with the pins 35... via a jig 36, and then the pins 35...
A positioning method was used in which the ... was removed and processed.

(Problems to be Solved by the Invention) However, as described above, in the conventional method, the positioning and movement of the saddle 10a, the milling heads 6a, 6a, and the positioning of the workpiece 17a are extremely complicated, and therefore the machining work is extremely difficult. The fatal problem was that it took a lot of time and the workability was extremely poor.

Furthermore, during machining, it is necessary to replace the table 34 as appropriate depending on the size of the workpiece 17a, and therefore there is also the problem that a large number of tables 34 with different dimensions must be prepared.

Therefore, the present invention has been made to solve these conventional problems, and its purpose is to make a series of processing operations such as mounting a workpiece, positioning the workpiece, and machining the side surface extremely simple and quick.

The side surface machining machine according to this embodiment has the above-mentioned configuration, and an example of its use will be described next.

First, the electric motor 16 is started, and the distance between the slide tables 1 is adjusted according to the amount of cut into the workpiece 17. In this case, since the guide bodies 4, 4 of the workpiece mounting tables 3, 3 are engaged with the rails 13 of the slide tables 1, 1, the workpiece mounting tables 3, 3 mutually move along the guide rail 19. . Further, the positioning guide 24 is also arranged at a predetermined position via a gear 31 that is pivotally supported by one of the slide bases 1. At this time, release the stopper and release the handle 32.
By rotating the rack 29, the gear 31 moves the rack 29, which allows the guide plate 30 to be moved and its arrangement to be finely adjusted.

Next, in this state, as shown in Figure 2, the work 1
7 is brought into contact with the inner surface of the guide plate 30, and the workpiece is placed across between the workpiece mounting tables 1 and 1, and then the hydraulic cylinders 21 and 21 are actuated to clamp the workpiece with the clamp plates 25 and 25. Clamp 17.
In this case, the workpiece 1 is placed above the workpiece mounting tables 3, 3.

Since the parts 21 are integrally attached, the workpiece 17 can be clamped well and quickly.

In this way, the work 17 can be positioned extremely easily.

Thereafter, when the electric motors 9, 9 are started to rotate the milling cutters 7, 7, and the saddle 10 is transferred in the direction A by the hydraulic cylinder, the workpiece mounting tables 3, 3 are engaged with the guide rails 19 of the saddle 10. Since the workpiece mounting tables 3, 3 are also moved in the A direction at the same time, both sides of the workpiece 17 are attached to the milling cut. Cutting is carried out by machines 7, 7. Thereafter, when the saddle 10 is moved in the opposite direction, both side surfaces of the workpiece 17 are chamfered by the chamfering cutters 8, 8, and then the clamps are released and the workpiece 17 is removed from the workpiece mounting tables 3, 3. This completes the cutting of both sides of the workpiece 17.

In the above embodiment, the saddle 10 is configured to reciprocate in the A direction, but the slide bases 1, 1 may be configured to reciprocate in the A direction. In this case, for example, as shown in FIG. 3, rails 36, 36 are laid at predetermined positions on the processing machine main body 11, and concave grooves 37, 37 are slidably fitted into the rails 36, 36 on the lower surface. The slide bases 1, 1 are fixed to tables 38, 38a provided with

Furthermore, both slide platforms 1, 1 do not necessarily have to be constructed so that they can move in the direction facing each other; it is sufficient that at least one of them can be constructed so that it can move in the direction facing each other.

Further, the positioning guide 24 and the mechanism that allows fine adjustment of the amount of movement of the positioning guide 24 are as follows:
It is not necessarily necessary to provide it.

Furthermore, if the hydraulic cylinders 21, 21 as a clamping means for the workpiece 17 are integrally provided above the workpiece mounting tables 3, 3 as in the above embodiment, the above-mentioned preferable advantages can be obtained. does not necessarily need to be provided on the workpiece mounting tables 3, 3, and its specific configuration does not matter. still,
As the clamping means, an air cylinder may be used in addition to a hydraulic cylinder, or magnets may be provided on the workpiece mounting tables 3, 3, and the specific means thereof is not limited.

Further, in this embodiment, since the chamfering cutters 8, 8 were provided, an advantage was obtained in that the workpiece 17 could be chamfered by the reciprocating movement of the slide bases 1, 1 or the saddle 10. Providing the chamfering cutters 8, 8 is not an essential condition of the present invention.

Furthermore, the side surface machining machine according to the present invention is not limited to cutting as in the above embodiment, but can also be applied to, for example, cutting by changing the processing tool. Further, the feeding and unloading of the work 17 to the side processing machine can also be automated by using a belt conveyor or the like.

In addition, the shapes of each part of the slide table 1, workpiece mounting table 3, and saddle 10 can be changed as desired within the scope of the present invention.

(Effects of the Invention) As described above, the present invention is configured such that the workpiece mounting table can move back and forth in the front and rear directions in conjunction with the slide table arranged oppositely. By moving the workpiece in the direction and adjusting the interval according to the machining dimensions of the workpiece, the workpiece mounting table and the processing tool are moved and arranged at predetermined positions in conjunction with the slide table.

That is, the workpiece mounting table can be moved extremely quickly according to the machining dimensions of the workpiece.

Moreover, since the workpiece mounting table is configured to be able to move freely in the reciprocating direction of the slide table or the saddle (the direction that intersects the reciprocating direction of the slide table), the slide table or the saddle can reciprocate. By moving the workpiece in the direction of movement, both sides of the workpiece can be machined, resulting in the exceptional effect that the series of machining operations involved in this work are extremely simplified.

Furthermore, if a positioning guide is provided in conjunction with the slide table for positioning the workpiece by bringing the side surface of the workpiece into contact with the lateral position of the workpiece mounting table,
By moving the slide table facing each other in the front-rear direction and adjusting the interval therebetween according to the machining dimensions of the workpiece, the workpiece mounting table and the positioning guide move simultaneously in conjunction with the slide table.

Therefore, the workpiece can be positioned simply by bringing the side surface of the workpiece into contact with the positioning guide and placing it astride the workpiece mounting table, making this positioning work much easier than in the past. The process can be carried out quickly and efficiently, resulting in a remarkable improvement in work efficiency.
