Description

The burnishing device of the automatic compensating action of a kind of tool

The utility model relates to a kind of burnishing device, relates in particular to the burnishing device of the automatic compensating action of a kind of tool.

Commonly use polishing machine for seeing through control structure startup work motor, driving the cloth wheel by the work motor again rotates, then handle the rocking arm of polishing machine, make rocking arm drive the work motor simultaneously and cloth takes turns to the position location, the reprocessing workpiece, so well known, the cloth wheel must produce loss after the certain workload of processing, just can lower the polishing size that when the location, is reached originally thus, make operating accuracy can't reach requirement, such situation can be adjusted the location dimension of cloth wheel again and improved by the worker, and this action the dealer mostly be called＜revisal〉or＜repaid, this one＜revisal〉size need lean on the operator to adjust voluntarily, it not only accumulates man-hour because of action frequency increases, the operating efficiency of processing also can't promote, the more difficult growth of putting forward economic benefit, and this is locating of can't breaking through of present process technology;

Moreover, aforementioned＜revisal〉and processing can not be synchronous, and rely on manually a lot of, so that obviously problem on the high side of fraction defective can occur processing, for the operator, more need pay special attention to the operator reach slightly hastily carelessness, accidentally, emotional lability or the unconsummate person of technology, therefore the higher situation of fault rate all takes place easily, just need scrap and cause producing in the processing defective products, work in-process is error so that scrappage increase situation easily, not only reduce production efficiency, and material cost, time cost detracts meaninglessly is for the very big loss of dealer, makes the dealer extremely perplex.

Main purpose of the present utility model is: in the mode of automatic revisal, make control module when polishing, change situation by the electric current of detecting cloth wheel motor, thereby make control module can take charge of the revisal of control compensating unit, make reciprocating structure can heavily cover polishing, under revisal synchronously, finish polishing to same precision.

For achieving the above object, the utility model is mainly by facility, compensating unit, reciprocating structure, grinding seat and control module and is constituted, facility are provided with compensating unit, control module in the appropriate location, and are provided with reciprocating structure in compensating unit, then are provided with on this reciprocating structure to grind seat;

Grinding seat mainly is made up of motor, belt, main shaft and cloth wheel; But its motor mat belt drives is hubbed on the main shaft in the framework, makes the cloth wheel that is mounted on the main shaft cooperate reciprocating structure and the workpiece on the workbench is polished;

The electric current that grinds the seat motor then is provided with current sensor through the place, and current sensor and control module link;

Control module is provided with display, the size of current that can show current sensor institute sensing, and be provided with current setting circuit, current comparison circuit in the control module at least, make control module can drive compensating unit, make compensating unit add in polishing at any time and force the revisal reciprocating structure man-hour, and reciprocating structure can drive cloth wheel and carries out polishing.

Described compensating unit includes horizontal collocation structure, longitudinal compensation structure.

Described facility are for being located between horizontal collocation structure, the longitudinal compensation structure.

After adopting said structure, grind the variation and the control adjustment of comparing of electric current of the motor of seat by detecting, make compensating unit can when polishing, force the revisal reciprocating structure, make reciprocating structure drive grinding seat heavily cover work is machined to certain precision, avoid cloth wheel can have influence on machining accuracy adding the abrasion loss that produces man-hour, and reach the purpose of synchronous processing and revisal, thus significantly save man-hour and promote production efficiency, promote quality effectively.
