In detail, the support plate 10 is formed in the shape of a rectangular metal plate through which the engaging holes 12 penetrate the upper and lower surfaces of the support plate 10, and the fixing bolts passing through the engaging holes 12, As shown in FIG.

The bracket 11 is formed in a rectangular block shape having the coupling portion 11a on the upper surface thereof. The bracket 11 is welded to one upper surface of the support plate 10 so as to be spaced apart from each other in forward and backward directions.

At this time, an arc-shaped guide portion 13 protruding upward is formed in the engaging portion 11a.

3, the guide portion 13 includes a vertical portion 13a extending along the inner surface of the engaging portion 11a and a protrusion 13a extending laterally from the upper end of the vertical portion 13a. (13b) having a T-shaped cross-sectional shape.

The support block 21 has a semicircular shape with a diameter corresponding to the diameter of the engaging portion 11a and is welded to one end of the angle plate 20. [

At this time, a coupling groove 21a into which the coupling portion 11a is slidably inserted is formed on the circumferential surface of the support block 21.

As shown in FIG. 3, the coupling groove 21a has a T-shaped sectional shape corresponding to the vertical portion 13a and the protruding portion 13b.

4, in a state where the support block 21 is coupled to the bracket 11 such that the engagement portion 11a is inserted into the engagement groove 21a, The support block 21 is rotated in a state in which it is in close contact with the inner circumferential surface of the guide portion 13 so that the inclination of the angle plate 20 can be adjusted.

At this time, graduations (14, 24) indicating the inclination of the angle plate (20) are displayed on the front surfaces of the bracket (11) and the support block (21).

And a fixing screw 15 which is coupled to penetrate the circumferential surface of the bracket 11 and whose distal end is in close contact with the circumferential surface of the support block 21. [

A screw hole 16 extending to the engaging portion 11a is formed on the circumference of the bracket 11 and the screw 15 is screwed into the screw hole 16, .

Therefore, when the fixing screw 15 is tightened after the inclination of the support plate 10 is adjusted, the front end of the fixing screw 15 is pressed against the circumferential surface of the support block 21 to form the angle plate 20, To prevent it from moving.

The work fixing jig having the above-described structure includes the support plate 10 having the bracket 11 formed on one side thereof with an arc-shaped engaging portion 11a recessed downward on the upper surface thereof, And an angle plate 20 having a support block 21 rotatably coupled to the coupling portion 11a at one side thereof. The coupling portion 11a of the bracket 11 is provided with an arc- And a coupling groove 21a to which the guide portion 13 is coupled is formed on a circumferential surface of the support block 21. [

Therefore, the inclination of the workpiece fixed to the angle plate 20 can be freely adjusted by rotating one end of the angle plate 20 up and down to adjust the inclination of the angle plate 20. [

Particularly, the guide portion 13 has a vertical portion 13a extending along the inner side surface of the engaging portion 11a and a protruding portion 13b extending laterally from the upper end of the vertical portion 13a. And the engaging groove 21a is formed in a T-shaped cross-sectional shape corresponding to the vertical portion 13a and the projecting portion 13b of the guide portion 13, The bracket 11 and the support block 21 can be freely slidably separated from each other by the coupling grooves 13 and the coupling grooves 21a.

Scales 14 and 24 indicating the inclination of the angle plate 20 are displayed on the front or rear side of the bracket 11 and the support block 21 so that the operator can adjust the inclination of the angle plate 20 There is an advantage that the inclination of the angle plate 20 can be accurately confirmed.

A fixing screw 15 for fixing the support block 21 and the angle plate 20 so as to prevent the support block 21 and the angle plate 20 from coming into contact with the circumferential surface of the bracket 11, So that the angle plate 20 can be freely adjusted and fixed.

5 to 7 illustrate another embodiment according to the present invention, in which gear teeth 23 are formed on the circumferential surface of the support block 21. FIG.

A rotary gear 31 rotatably coupled to the bracket 11 and having a peripheral surface engaged with the gear teeth 23 of the support block 21; A vibration detection sensor 33 provided at one side of the angle plate 20 for measuring vibration transmitted to the angle plate 20, (35) connected to the rotation detection sensor (32) and the vibration detection sensor (33) and controlling the operation of the alarm means (34) Respectively.

To this end, the engaging portion 11a of the bracket 11 is formed with a concave portion 17 downwardly concave

The rotary gear 31 is rotatably coupled to the inside of the concave portion 17 by a laterally extending rotary shaft 31a so that the rotary gear 31 rotates in a vertical direction when the angle plate 20 is rotated in the vertical direction .

The rotation detecting sensor 32 is provided inside the recess 17 and outputs light to the circumferential surface of the rotary gear 31 and receives light reflected from the circumferential surface of the rotary gear 31, And senses the rotation of the rotary gear 31 to sense the rotation of the support block 21 and the angle plate 20. [

As described above, when the rotation gear 31 is rotated, a variety of rotation detection sensors 32 for sensing and outputting a signal are developed and used.

The vibration detection sensor 33 is disposed on the lower side of the angle plate 20 so that vibrations transmitted to the angle plate 20 when the pigments tied to the angle plate 20 are processed using a machine tool Function.

The alarm means 34 comprises a speaker for outputting a warning sound and a lamp for outputting a light.

The control means 35 receives the signals of the rotation sensor 32 and the vibration sensor 33 and detects that the vibration is generated in the angle plate 20. At the same time, The angle plate 20 is rotated by the external force applied to the workpiece and the angle plate 20 while the workpiece fixed to the angle plate 20 is being machined using the machine tool, It is configured to warn the operator by determining that the plate 20 is to be rotated and driving the warning means 34. [

That is, when a workpiece fixed to the angle play is machined by using a machine tool, an external force is applied to the workpiece and the angle plate 20.

The angle plate 20 is fixed by the fixing screw 15 so that a strong external force is applied to the angle plate 20 while the angle of the angle plate 20 is fixed by the fixing screw 15 The angle plate 20 can be rotated upward or downward.

As described above, when the workpiece is machined by using the machine tool, when the angle plate 20 is rotated by the external force applied to the workpiece and the angle plate 20, the machined workpiece is defective Can

Accordingly, the control means 35 receives the signal of the vibration detection sensor 33, detects whether or not the workpiece is to be machined by using the machine tool, and processes the workpiece by using the machine tool It is detected whether the angle plate 20 is rotated by receiving the signal of the rotation detecting sensor 32. When it is detected that the angle plate 20 is rotated by the rotation detecting sensor 32 , It is determined that the angle plate 20 has been rotated by an external force applied by the machine tool and the alarm means 34 is operated to warn the operator that the angle plate 20 has been rotated.

In contrast, when it is sensed that the angle plate 20 is pivoted to the rotation detection sensor 32 in a state where no vibration is detected in the vibration detection sensor 33, the control means 35 controls the angle plate 20 in the up and down direction to adjust the inclination of the angle plate 20 so that the alarm means 34 is not operated.

When the workpiece fixed to the angle plate 20 is machined by using the machine tool, the workpiece fixing jig having the above-described configuration is rotated by the external force applied to the workpiece and the angle plate 20, The worker can quickly check and detect the abnormality by detecting the abnormality, so that the workpiece is processed in a state in which the inclination of the angle plate 20 is unintentionally changed, There is an advantage that it can be prevented.
