As can be seen from these drawings, the scroll machining chuck assembly of the scroll compressor according to the present invention has a disc-shaped base 200 having a spindle coupling hole 210 into which the spindle spindle 100 is inserted and coupled.

The base 200 has a sliding guide 230 which is rotated around an axis by the rotation of the spindle 100 and is elongated along the radial direction at a predetermined angle interval around the spindle 100. Here, three sliding guides 230 are disposed at intervals of 120 degrees around the spindle 100. The spacing and number of the sliding guides 230 can be changed according to the design.

Each slider 230 is provided with a slider 300 movable in the radial direction. The slider 300 is moved synchronously by the slide driving unit provided on the base 200. The slider 300 may be moved in connection with the hydraulic driving unit provided on the shelf. The slider 300 includes a frame 310 received in the sliding guide 230 and moving along the radial direction and a connection bracket 330 coupled to the frame 310 to form a predetermined seating space. The frame 310 has a plurality of bracket fastening holes 315 for engaging with the connecting bracket 330.

The connection bracket 330 includes a plate-shaped base portion 331 having a fastening hole 333 corresponding to the fastening hole 315 of the frame 310, And a support block seating portion 335 extending along the direction of the support block. The connection bracket 330 is fixedly coupled to the frame 310 as the fastening bolt 334 is inserted into the fastening hole 333 of the bracket 330 and the fastening hole 315 of the frame 310 at the same time.

A support block 400 is installed in the seating space formed by the base portion 331 of the connection bracket 330 and the support block seating portion 335. The support block 400 has a fastening slot 430 extending radially of the base 200 so as to be positionally adjustable in a radial direction with respect to the connection bracket 330. The base portion 331 of the connection bracket 330 has a fastening hole 332 for fastening with the fastening bolt 431 inserted through the fastening slot 430. Accordingly, the support block 400 can be positioned at a predetermined distance in the radial direction by a length formed by the fastening elongated hole 430 with respect to the connection bracket 330.

The support block 400 has a fastening hole 410 through which the fastening bolt 338 can be inserted in the radial direction on the outer circumferential surface of the end portion of the fastening block 400. The support block seat portion 335 of the connection bracket 330 is supported by the support block 400, And a fastening hole 337 corresponding to the radial fastening hole 410 of the fastening portion 400. On the other hand, when the supporting block 400 is spaced apart from the supporting block receiving portion 335, a plate-shaped gap filling member 440 is inserted into the gap. The gap filling member 440 also has a fastening hole 441 corresponding to the radial fastening hole 410 of the support block 400. Accordingly, the support block 400 is fastened to the connection bracket 330 simultaneously in the axial direction and the radial direction, and the coupling strength thereof is relatively high. The support block 400 has a circular adjustment block receiving groove 450 in which a control block 500 rotatable about an axis parallel to the spindle 100 is received. The adjustment block receiving groove 450 has an adjusting block 500 inserted therein.
