However, when using such a conventional angle stand 31, the inclination angle θ° of the inclined surface 31g is fixed. must be replaced with.

Therefore, many types of angle tables are required depending on the type of slope angle of the workpiece to be machined, but this poses a problem because the manufacturing cost of these many angle tables (approximately 500,000 yen per unit) is high. .

Another problem is that the work efficiency decreases due to the replacement of the angle table.

Therefore, recently, NC machining 8! using the table tilt method or universal attachment method is used to process workpieces with such sloped surfaces. A machine is used, and the angle table section uses NCjitllll and digital display to
A workpiece having a desired inclination angle can be freely manufactured.

However, these machines are extremely expensive (
In addition to costing several tens of millions of yen, there is also the problem of requiring knowledge and skill regarding NC.

The present invention was proposed in view of this situation, and
It is an object of the present invention to provide a tilting table device that has sufficient rigidity to withstand cutting resistance, can improve workability by changing the tilt angle θ as appropriate, and can be manufactured at low cost. .

Since the tilting table device as an embodiment of the present invention is constructed as described above, its operation is performed as follows.

First, install this device on a machine (not shown), and
The setting key grooves 1a are set in the keys (not shown) on the machine and fixed.

Then, a workpiece to be processed (not shown) is set on the table board 3 of the present device and mixed therein. At this time, the clamp formed on the table board 3 determines and fixes the direction of the workpiece to be processed via a set key (not shown) fitted in the T-shaped groove 22.

Next, the table board 3, which is normally in a horizontal state (inclination angle 0°) when not in use, is tilted to a required angle.

To do this, follow these steps:

First, a total of eight clamps KA hM c 1 (first clamps KA hM c 1) 10 are tightened on the vertical wall portions 2 at both ends, and a second clamp rock structure C2 is located in the middle of the table board 3.
Loosen each clamp bolt 14. At this time,

4b and each engagement surface (approximately 2.0a+m) to provide a margin (.

Next, remove the two positioning m-bins 7 inserted into the pins 60 of the end plates 4 on both sides with an inclination angle of 0°.
If it is difficult to pull out by hand, use a tool such as a punching nut to pull it out.

By the above-described operation, the table board 3 becomes freely rotatable around the rotation axis 3a, and tilting becomes possible.

Following this, an operation is performed to tilt the table board 3 to a required tilt angle.

That is, an air tool (not shown) connected to factory air is attached to the joint 16, and the reduction gear 17 is started by the factory air. Alternatively, an impact wrench (not shown) set in the direction in which the table board 3 can be tilted (clockwise in this embodiment) may be aligned with the pongee of the dead rock 17 and started. As a result, the table board 3 and the end plate 4 begin to be tilted by the drive mechanism A described above.

Then, while looking at the rough scale displayed on the end plate 4, supply factory air or reduce the impact wrench, and when the required angle of inclination is achieved, remove the air tool from the joint 16 (or decelerate the impact wrench). 8!
(removed from 17).

Furthermore, if necessary, while rotating the reducer 17 by hand,
Fine adjustment is made so that the pin hole 6 with the end plate 4 and the bottle hole 5 with the raised portion 2 are aligned at the required angle of inclination.

When such angle adjustment is completed, the two positioning pins 7 are inserted through the pin holes 5 of the vertical wall portion 2 and engaged with the pin holes 6 of the end plate 4, thereby completing the positioning.

After irt, the first part of the compatible wall part 2 that had been loosened is
10 clamp bolts of Cranonpu B'tiC1, 8 in total, and 1 clamp bolt of the second clamp rock structure C2 in the middle part
4 to each oak) 10c and 14a, and the fixing of the inclined table board 3 to the base 1 is completed.

On the other hand, when the tilted table 53 is returned from the tilted state to the horizontal (0°), the same operation tl is performed.

In other words, first, the clamp pole of the first clamp rock structure C1)
10 and the clamp bolt 14 of the second clamp tP1 h'ff C2.

Next, a total of two positioning pins 7 inserted into the pin holes 6 of both end plates 4 are removed.

Furthermore, either attach an air tool to the clamp bolt 10 of the reduction plate 17 and use factory air, or use an impact wrench set to rotate the table board 3 in a direction such that the inclination angle is 0° (that is, counterclockwise rotation). to start the speed reducer 17 and rotate the table board 3 and end plate 4. At this time, while looking at the rough scale displayed on the end plate 4, supply factory air or drive the impact wrench), and when it becomes horizontal (angle of inclination 0°), move the air tool from the joint 16 (or drive the impact wrench). Remove the wrench (from the reducer 17).

Furthermore, while turning the speed reducer 17 by hand, finely adjust the bottle hole 6 with the end plate 4 indicating horizontal alignment and the bottle hole 5 with the vertical wall part 2, and then adjust the two positioning bottles 7. It is inserted through the bottle hole 5 of the vertical wall portion 2 and engaged with the bottle hole 6 with the end a4.

When the positioning is completed, the four clamp bolts 10 of each of the loosened first clamps IAc1 and the clamp bolts 14 of the second clamp C2 are tightened to fix the horizontal table board 3.

Note that during these operations, it is also necessary to perform safety checks such as cleaning and lubricating each sliding part, and checking that there are no objects interfering with the table tilt range.

In this way, the tilting table device of the present invention can be used for driving! i!
By using lJ Iso 4'VA and the positioning pin 7, the inclination angle of the table board 3 can be freely changed from Oo to 60° in 5° intervals, and the desired angle can be set extremely easily. like,! There is no need to replace the device for each krI oblique angle. This has the effect of improving work efficiency, and also
Fi! Since it does not include an IO'l device, it has the advantage of being able to be produced at low cost as a workpiece installation stand.

First clamp Isokei C1 that clamps the end plate 4 to the standing wall portion 2
and a second clamp that clamps the middle part of the table board 3 to the base 1.
Since the clamp rock 117C2 is provided, the table board 3 is reliably fixed on the base 1. This makes it possible to have sufficient rigidity to withstand cutting resistance during workpiece machining, and has the effect of reliably damping the workpiece by one degree of vibration during workpiece machining.

By the way, this tilting table device is placed on the machine,
Moreover, a workpiece for processing is set on the tilting table device, and processing such as cutting is performed. Therefore, the height of the tilting table device must be kept as low as possible.

Therefore, as shown in FIG. 7, in the embodiment, the height is 11 when the table board 3 is at the horizontal inclination angle (0°) position.
1 is set low at about 500mm, and table board 3
