Abstract

A fixing mechanism for a brush roller of a circuit board grinding machine comprises a transmission shaft (10) and a brush roller (20) sleeved on the transmission shaft (10). A positioning conical disk (30) is disposed at a positioning end (11) of the transmission shaft (10), and a first conical hole (211) matching with the positioning conical disk (20) in taper is disposed at a positioning end of a center hole (21) of the brush roller (20). The fixing mechanism further comprises a moving pressure disk (40) and a nut pressure disk (50), wherein the moving pressure disk (40) is movably sleeved to a fixed end (12) of the transmission shaft (10), the nut pressure disk (50) is in threaded connection with the fixed end (12) of the transmission shaft (10), and the nut pressure plate (5) jacks the moving pressure disk (4) to press the brush roller (20). According to the technical scheme, impact of opposite force of the brush roller upon the fixing mechanism is avoided, the brush roller is stable in operation without jumping and axial play, and quality of a ground board is guaranteed.

Description

technical field [0001] The invention relates to mechanical structure design, in particular to a fixing mechanism for a brush stick of a circuit board grinding machine. Background technique [0002] At present, the assembly of the brush roller and the transmission shaft of the grinding machine brush roller used in the circuit board industry is to put the brush roller into the transmission shaft. One end of the brush roller has a hole with a keyway, and the outer edge of the hole is chamfered. On the taper of the tapered boss of the drive shaft, the keyway is installed in conjunction with the key on the drive shaft; a round nut with a tapered boss is screwed into the thread at the other end of the drive shaft to tighten the other end of the brush roller The outer edge of the hole is tapered. In order to prevent it from loosening, a round nut is screwed in to compress the front round nut to form an assembly combination of the brush roller and the drive shaft. However, in this ...
