[0032] Usage method of a fixture mechanism with translation function:
[0033] When clamping the faucet housing: the piston rod of the sliding cylinder 30 extends to drive the pull rod 13, the abutting rod 17, and the abutting block 18 to slide forward. The abutting block 18 does not abut against the fixture head 15, and the front end of the fixture head 15 closes. The faucet housing is sleeved on the fixture head 15. Subsequently, the piston rod of the sliding cylinder 30 retracts to drive the pull rod 13, the abutting rod 17, and the abutting block 18 to slide backward. The abutting block 18 abuts against the fixture head 15, and the front end of the fixture head 15 expands and deforms to tension the faucet housing. And as the abutting block 18 further moves backward, the tension force becomes greater and greater to firmly clamp the faucet housing for polishing.
[0034] During polishing: the rotating motor 12 drives the pull rod sleeve 14 to rotate through the double-output-hole planetary reducer 11, and the pull rod sleeve 14 drives the disassembly and assembly joint 27, the fixture head 15, and the faucet housing to rotate.
