Description

A kind of polishing machine

Technical field

The utility model relates to a kind of polishing machine, relates in particular to a kind of sabot and unloads and coil polishing machine easily.

Background technology

At present, the small-sized polishing machine that can use by hand, because light, volume is little, and is easy to carry, becomes a kind of processing commonly used and surface-treated equipment, and is widely used in all trades and professions.As the patent No. is that the Chinese utility model patent " polishing machine of the auxiliary structure that stops operating fast of tool " of ZL200520118238.0 (notification number is CN2858182Y) discloses so a kind of polishing machine.This polishing machine comprises a body, is arranged on intrinsic groups of motors, covers an annular dust cover and a polishing disk on the body bottom peripheral edge, wherein, the output shaft of groups of motors is extended with an eccentric wheel downwards, eccentric wheel is stretched out outside the end face of body, eccentric bottom offers screw, and the medial surface center of polishing disk is provided with screw rod, this screw rod just is threaded in the screw of eccentric wheel bottom, when polishing machine is worked, push switch, groups of motors can drive polishing disk and do centrifugal beat running.

Because eccentric wheel can arbitrarily be swung by relative body, and the polishing disk area is bigger, need constantly to rotate whole polishing disk, its center screw flight could be connected in the eccentric screw, in the installation polishing disk and dismounting polishing disk process of reality, polishing disk tends to can not be threaded onto accurately and rapidly in the eccentric wheel owing to eccentric swinging, if polishing disk connects not in place in the eccentric wheel bottom, deviation is perhaps arranged, all can directly influence the polishing effect of polishing machine.Thereby existing polishing machine needs further improvement.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of polishing machine at the present situation of prior art, its bearing block and eccentric wheel can conveniently be located, thereby make the eccentric relatively installation and removal that are in transmission connection of polishing disk become convenient, accurate and quick.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this polishing machine, include body, be arranged on an intrinsic groups of motors and a polishing disk, wherein, the output shaft of described groups of motors is extended with an eccentric wheel to the end face direction of body, this eccentric wheel stretches out on the end face of body, the medial surface of described polishing disk is provided with vertical center bolt, it is characterized in that:

Be connected with a bearing block on the described eccentric end, offer screw on the outer face of this bearing block, the center bolt of this polishing disk just is threaded in the screw of bearing block;

And, also be provided with a fixed head on the end face of described body, this fixed head has the through hole that passes for bearing block, the end of one set bolt is passed the aperture on the fixed head and is threaded onto in the screw on the body end face, make this fixed head can be around this set bolt and body end face rotation relatively, simultaneously, have a cutting to bearing block direction protrusion on this fixed head, and described bearing block offers a jack that matches in the position that correspondence is transplanted a cutting.

As further improvement, aperture on the described fixed head can be opened in the fixed head from bearing block that side farthest, and described bolt head periphery also is provided with a balancing weight, thereby make fixed head when this aperture center rotates, the movable amplitude of transplanting a cutting can be bigger, its interior amplitude of jack that is inserted into bearing block will be longer, improves the position-limiting action to bearing block.

When practical set, if the tension that set bolt is twisted fixed head, then fixed head relatively the body end face easily rotate, if that twists is loose excessively, then arbitrarily rotation of fixed head, when polishing machine polished, the cutting meeting accident of fixed head was touched the bearing block in the rotation, cause parts damages, polishing machine also can't operate as normal.For making fixed head only apply under the situation of external force and could rotate relative to the body end face, and controlling and not being effort very to fixed head, described bolt is outer, can be equipped with the V-type rubber sheet gasket between bolt head and fixed head lateral surface, setting by the V-type rubber sheet gasket, certain damping action is played in random slip to fixed head, and the V-type rubber sheet gasket has certain elastic reaction, during with external force rotational fixation plate, and effort that neither be very.

Described bearing block and the eccentric mode of being in transmission connection can adopt existing various technology, and simply, described bearing block can be threaded in outside the eccentric end.

As further improvement, can be marked with the relative arrow of both direction on the described fixed head, two arrows towards with transplant a cutting that direction is set is parallel, also, two arrows are all towards the position of fixed described bearing block, to make things convenient for the user to operate, promote fixed head in a direction indicated by the arrow, it is rotated relative to the body end face, the cutting of fixed head can accurately be inserted into the jack on the bearing block, perhaps convenient cutting breaks away from the jack on the bearing block, removes and inserts.

Compared with prior art, advantage of the present utility model is: by the fixed head that can rotate relative to body location and the setting of eccentric wheel top chock, cutting on the fixed head can movable be inserted in the jack of bearing block, and bearing block and the relative body of eccentric wheel are located, polishing disk can be threaded onto in the screw of bearing block quickly and accurately, promptly, make the installation and removal of the relative eccentric wheel of polishing disk bottom become convenient, accurate and quick, guarantee reliability and accuracy that polishing disk is in transmission connection, when needing to remove to bearing block and eccentric location, only need oppositely to promote fixed head, the jack that makes its cutting break away from bearing block gets final product, and is simple to operate laborsaving.
