Abstract
The invention relates to a grinding mechanism of an abrasive belt grinding machine and belongs to the field of grinding machining. A driving wheel, a tension device, driven wheels, two same displacement devices, two same rotary devices and a force applying device are fixedly connected with a supporting plate separately. Two same contact wheel modules are connected with the front ends of two same rotary devices separately. An abrasive belt is installed on the driving wheel, the driven wheels, the tension device and the contact wheel modules in a sleeving manner. The grinding mechanism has the advantages of being novel in structure and capable of being used for grinding and polishing of a workpiece with complex curved surfaces. Compared with the contact type grinding of a conventional grinding machine mechanism, the workpiece can be ground by the abrasive belt both in a direct float contact manner and in a contact manner; the free degree of a machine tool of the whole grinding mechanism is increased by using the displacement devices and the rotary devices, so that a grinding head of the abrasive belt can move up and down and rotate and the operation is easy.

Summary of the invention
The present invention provides the grinding mechanism of a kind of abrasive belt grinding machine, to solve owing to general-purpose grinder uses the processing of contact wheel contact, cause grinding allowance skewness, machining accuracy is poor, profile difficult quality guarantee, even causing grinding became uneven in curved surface polishing, homogeneity of product is difficult to ensure that, the problem that working (machining) efficiency is low.
The present invention adopts the technical scheme that: drivewheel, tensioner, driven pulley, two same displacement devices, two identical tumblers, force application apparatus are fixed with gripper shoe respectively and are connected, two identical contact wheel assemblies are connected to the front end of two identical tumblers, and abrasive band is sleeved on drivewheel, driven pulley, tensioner and contact wheel assembly；
The structure of tensioner of the present invention is: regulating wheel is fixing on the supporting plate by spring and base plate；
The structure of gearshift of the present invention is: be made up of slide bar, sliding sleeve and displacement cylinder, and slide bar is fixing with gripper shoe to be connected, and displacement cylinder two ends connect firmly respectively on slide bar and sliding sleeve, and sliding sleeve is connected with sliding bar；
The structure of tumbler of the present invention is: hinged with sliding sleeve by bearing pin, and rotation cylinder two ends are hinged with sliding sleeve and swing arm respectively；
The structure of contact wheel assembly of the present invention is: contact wheel is rotationally connected with multidiameter by bearing, and this multidiameter is fixing with swing arm to be connected；
The structure of force application apparatus of the present invention is: force cylinder connects with being connected assembly, has spring between this connection assembly and pressing plate, and force cylinder is fixing with gripper shoe to be connected.
It is an advantage of the invention that novel structure, for complex curved surface part grinding and polishing, compared with conventional grinding machine mechanism contacts formula grinding, both abrasive band can have been made directly to float with workpiece and to have contacted grinding, may make contact again formula grinding, whole grinding mechanism utilizes gearshift and tumbler to increase lathe degree of freedom, and it makes abrasive belt grinding head can move up and down and rotate, easy and simple to handle；Meet in Grinding Process, complex-curved free grinding and the contact grinding of different curvature curved surface, different tool combinations, act on the different location of workpieces.Present invention is more particularly directed towards the polishing processing of deep camber Irregular Boundary Surface, there is preferable machining accuracy, have good application prospect in sbrasive belt grinding field.
