The ball joint member 430 includes a supporting portion 431 coupled to the upper side of the moving block 420 and a ball joint socket 432 coupled to enclose the upper outer circumferential surface of the supporting portion 431 and having a space formed therein, A ball stud 433 which is accommodated in a space portion of the ball joint socket 432 and is supported at the upper end of the support portion 431 and a shaft portion 433 which is coupled to one side of the ball stud 433 and extends to the outside of the ball joint socket 432, Gt; 434 < / RTI >

At this time, the ball joint socket 432 is axially rotatably coupled to the support portion 431, and a receiving groove (not shown) is formed at the upper end of the support portion 431 to receive the lower end portion of the ball stud 433.

A guide groove 435 is vertically cut in the upper end of the ball joint socket 432 so as to communicate with an internal space portion of the ball joint socket 432. A shaft portion 433 coupled to one side of the ball stud 433 through the guide groove 435 434 extend outwardly. Therefore, the shaft portion 434 can rotate integrally with the ball stud 433, and can rotate in the vertical direction along the guide groove 435. [

A fixing member 436 is provided on one side of the outer circumferential surface of the ball joint socket 432. The fixing member 436 serves to fix the angle of the props 10 supported by the clamp 440 to be described later.

That is, the fixing member 436 is inserted into the space portion through the outer circumferential surface of the ball joint socket 432. When the end of the fixing member 436 inserted into the space portion is in close contact with the outer circumferential surface of the support portion 431, The ball joint socket 432 is prevented from rotating about its axis.

When the fixing member 436 pushes the supporting portion 431, the ball stud 433 is brought into close contact with the inner circumferential surface of the ball joint socket 432 together with the supporting portion 431 so that the rotation of the ball stud 433 and the shaft portion 434 .

The clamp 440 includes a support block 442 having an insertion groove 441 formed at one side thereof for inserting a blade portion of the props 10 therein and a proximal end 10 which is inserted through one side of the support block 442 And a fastening member 443 for pressing and supporting.

At this time, the support block 442 includes a coupling portion 444 coupled to an end of the shaft portion 434 by a fastener such as a bolt, and a support portion 444 extending vertically along both side edges of the coupling portion 444, A pair of side walls 445, and a space between the pair of side walls 445 forms an insertion groove 441.

The proximal end 10 to be polished is inserted into the insertion groove 441 such that the blade portion is exposed to the outside and at least one of the coupling members 443 is inserted into the insertion groove 441 through one side wall 445 And presses and supports one side of the props 10. At this time, the edge of the side wall 445 may be formed in an arc shape so as to facilitate gripping of the props 10.

The tool polisher 100 according to the embodiment of the present invention can operate as follows.

First, the blade portion of the props 10 to be polished is inserted into the insertion groove 441 of the clamp 440 so as to be exposed to the outside, and the fastening member 443 is fastened and supported.

Then, the clamp 440 is rotated or vertically rotated so that the props 10 make an appropriate polishing angle with respect to the polishing wheel 300, and the fixing member 436 is fastened and fixed.

When the driving motor 500 is operated, the polishing wheel 300 rotates. When the moving block 420 is moved along the guide rail 410, the blade of the props 10 is fixed to the surface of the polishing wheel 300 So that the polishing is performed.

At this time, when the shaft portion 434 and the clamp 440 are rotated in the vertical direction along the guide groove 435 of the ball joint socket 432, the proximal end 10 moves in a curved trajectory on the surface of the polishing wheel 300 I pass through it. Therefore, even in the case where the edge of the props 10 is curved, the clamp 440 can be polished along the edge while rotating the clamp 440, so that it is possible to prevent the edge from being clogged by mistake during polishing.

When the one side polishing of the blade is completed, the clamp 440 is rotated to remove the props from the polishing wheel 300, and then the moving block 420 is moved so that the opposite side of the blade faces the opposite side of the polishing wheel 300 The polishing of the blade on the opposite side can be continued. That is, it is not necessary to detach and replace the tool 10 from the clamp 440 for polishing the blade on the opposite side.

As another embodiment of the present invention, an actuator (not shown) may be installed on one side of the stationary member 400 to move the stationary member 400 in the forward and backward directions.

As an example, a driving cylinder (not shown) may be installed behind the guide rail 410, and a cylinder rod of the driving cylinder may be coupled to the rear surface of the moving block 420. As another example, a lead screw (not shown) that is rotated by a moving motor (not shown) is installed side by side with the guide rail 410, and the moving block 420 can be screwed to the lead screw. In this case, the moving block 420 moves along the lead screw and the guide rail 410 when the lead screw is rotated according to the driving of the moving motor.

When the moving block 420 is moved using the actuator as in the other embodiments of the present invention, the precision of polishing can be improved by controlling the contact area between the blade of the props 10 and the polishing member 320 to be constant .

Further, it is possible to continue the polishing work for a long time by continuously contacting the blade of the props 10 with the polishing member 320, or to perform the polishing operation intermittently by reciprocating the moving block 420 at regular time intervals, It is possible to carry out the work while checking.
