Description

[Detailed description of the invention] The present invention is used to form diagonal holes and sloped surfaces of 1" f2- in the object of machining a frame bridge made of wrought iron, for example (+21 below, referred to as the workpiece). This invention relates to an inclined machining tool.

Conventionally, when forming diagonal holes or inclined surfaces in a workpiece, if the workpiece is small (approximately 3 to 15 cm square), the bed of a milling machine tool is generally used. A vise, such as a milling vise or an aki-lock vise, is installed above the workpiece, and the workpiece is rotated using a sine bar or the like in the vise. '? This is done by tilting the workpiece at an angle of J by several degrees and then holding it in an 11th-century vise to drill holes, cutting, etc. ) If the workpiece is larger than cm square), generally an angle plate, circuit table, etc. is installed on the bed of the machine tool, and the machining surface of the angle plate, etc. is tilted to the desired angle, and the workpiece is This is done by fixing it on the 1111 work surface and performing drilling, cutting, etc. however,
The above-mentioned devices such as angle plates are not only large in size and have a complicated structure, but also have the ability to handle extremely large and long workpieces, such as plate-shaped workpieces nearly 1 meter in length. If diagonal machining is required, it is necessary to prepare even larger equipment and a corresponding large machine tool, which significantly increases machining costs.

The present invention has been made in consideration of the above-mentioned circumstances, and its purpose is that even if the workpiece is of a significantly large size or has a vertical length, it is possible to form diagonal holes or sloped surfaces in the workpiece. It is an object of the present invention to provide a small-sized, simple-structured, and inexpensive inclined machining tool that can form such shapes.

The tilting tool of the present invention has a pair of fixed blocks erected opposite each other on the bed of a machine tool, and is a block for horizontally supporting a workpiece, wherein each of the fixed blocks a pair of support blocks that are rotatably attached to the inside and at one end; a fixing member that fixes the support blocks to the fixed block while tilting the support blocks at an angle relative to the bed; and the support blocks and the bed. The device is characterized in that it has an intervening block that is interposed between the support block and supports the support block.

An actual example of the present invention will be explained based on the drawings under DJ.

Figure 1 or #! In Figure 3, 1 indicates the bed of a machining tool such as a milling machine. 2a and 2b are a pair of plate-shaped identification blocks (mostly made of iron) with 16 mm on the bottom.
By fitting the formed linear protrusions 3 into the parallel grooves 4 on the bed surface, they are erected on the L of the bed 1 facing each other. Each of the fixed blocks 2a and 2b has a rotary wheel hole 5 in the form of a circular hole formed at one end thereof, and a clamp elongated hole 6 formed in the form of an arc hole is formed at the end thereof at a predetermined distance (for example, 30 mm) from the center of the shaft hole 5.
cm spacing).

7a and 7b are a pair of support blocks having a substantially rectangular parallelepiped shape, each of which has a long support surface 9 on its upper surface for horizontally supporting the inner VC-handled workpiece 8. Each of the support blocks 7.1 and 7b has a rotating shaft hole 1O having the same diameter as the shaft hole 5 on one end side, and a round fixed shaft hole 11 on the other end side with the center of the rotating shaft hole 10. The distance between the shaft holes 5
Further, as shown in Figure 2, a support hole 12 is formed in the side wall surface of the fixed shaft hole 11 so as to communicate with the outside. Then, the rotary shaft 13 of the round shaft is inserted from the inside 11111 into the hard hob block 2a (2b) and the support block 7a (7b) through the two-1 moving shaft hole 5 and!

(7b), and for long tightening, insert the bolt 15 from the outside into the clamp disturbance 6 of the identification block 2a (2b), and tighten the bolt 15 on the fixed shaft 14.
By screwing the support block 7a (7b) into the screw hole 6 (Fig. 2) provided in the lost end of the bed and tightening the clamp, the movable support block 7a (7b) can be rotated at any angle with respect to the bed 1. t+! on the fixed block 2a (2b) in a state of slanting. d
Instead of using elements such as bolts and clamp slots, this filling and tightening can be done using other methods that fix the support block to the fixed block by tilting it at an arbitrary angle with respect to the bed. A fixing member may be provided.Furthermore, support blocks 7a and 7 for 17 and 171fi, respectively.
(b) a parallelepiped-shaped intervening block interposed between the inner fixed shaft 15 and the bed 1, and an inclined support block 7a;
Supports 7b. The intervening block 17 may be any block that is interposed between the support block and the bed and supports the support block, and its shape and intervening position are not limited.

First, a pair of identification blocks 2a and 2b are placed on bed 1.
The support blocks 7a are set upright facing each other with an appropriate interval, and then the rotation shafts 13 and 13 are inserted into the support blocks 7a,
7b is rotatably attached to the fixed block 12b, and then the supporting blocks 7a and 7b are moved together and tilted to a desired angle, and the bolts 15 or the like are used to tighten them to the VT1 constant block block 2ab, and then Intervening block 17.17
and support blocks 7a, respectively.

7h and the bed 10, and the workpiece 8 is placed horizontally between the support blocks 7a and 7b, and the machine tool is operated to perform drilling, cutting, etc., thereby forming a diagonal hole having a desired inclination angle. It is possible to create 11 configurations such as By moving the fixed positions of the support blocks 7a and 7b up and down, the angle of inclination of the diagonal holes, inclined surfaces, etc. can be changed to J-internal contact. In addition, by appropriately expanding or shortening the interval between fixed blocks (supporting blocks), it is possible to process not only relatively small workpieces, but also extremely large or long workpieces, for example, 1 m in length. Even if the workpiece is plate-shaped, it is possible to form desired diagonal holes or inclined surfaces in the workpiece.

In addition, the tilting tool of the example is made up of several blocks, is small in size, has a simple structure, and can be manufactured at low cost.

As shown in FIG. 3 for a lifting platform of a small-scale actual cloth example, the following equation holds true for the inclination angle α of the support block 7a. Here, the distance between the axes of the rotating shaft 13 and the fixed shaft 14, the height of the center of the rotating shaft 13 from the ped 1, the radius of the fixed shaft 14, and the axis 13 and 14, which represents the length from the rotation axis axis of the fishing line to the bed, /, hk and r are determined in advance to predetermined lengths, and the above formula is By using the intervening block 17 having the height of the X value calculated to give the inclination angle, it is possible to form a diagonal hole or the like having an accurate #j inclination angle.

As explained above, the inclined machining tool 1 of the present invention has a structure in which the workpiece is horizontally supported by a pair of support blocks that can be rotated at any angle. It is possible to form diagonal holes and # slopes with an inclination angle. Furthermore, by appropriately adjusting the interval between the support plotters al, it is possible to form diagonal holes and the like over a wide range of sizes. Furthermore, the tilting tool of the present invention is composed of several blocks, etc., has a small number of parts, is small, has a simple structure, and can be manufactured at low cost.
