The machine has the characteristics that a tension air cylinder is arranged at the lower end of the machine frame central beam, the end of a piston rod of the tension air cylinder is connected with the tension roller, and an abrasive belt rectifying mechanism is arranged at the piston rod end of the tension air cylinder. Therefore, the uniform and synchronous tensioning at both ends of the abrasive belt of the sanding machine with wide-breadth is solved through the matching between the tension air cylinder and the abrasive belt rectifying mechanism. Especially, for the sanding machine with the wide-breadth above 6 feet, the problem of asynchronous and uneven tensioning can be effectively solved, and therefore, the machine is worthy of being popularized and applied in the technical field.
Description
Technical field
The utility model relates to a kind of strainer, relates in particular to a kind of synchronous tension sander, belongs to the machining equipment technical field.
Background technology
As everyone knows, sander in operation process, evenly tensioning of two ends, abrasive band, otherwise will give a discount and scrap or serious sideslip occurs in the abrasive band.Especially, for large format sander more than six feet, because abrasive band breadth width dimensions is big, the two ends, abrasive band are difficult for even tensioning.Increase the structure that two auxiliary balloon overcome tensioning crossbeam rigidity deficiency, increase the active force fulcrum even adopt, also cause the tensioning crossbeam to produce reciprocal rotary movement easily.
Further, cylinder that lies in a horizontal plane in crossbeam inside, center of Italian imeas company's employing is realized idler roller two ends synchronous tension, no tensioning crossbeam by pinion and rack.This mechanism can satisfy large format sander structure needs well, but its structure more complicated is made the required precision height, and installation is adjusted cumbersome.Sweden steinemann company adopts two cylinders that are installed in tensioning crossbeam two ends to realize idler roller two ends tensioning, and tensioning crossbeam central point is as abrasive band correction revolution initial point.
But also there are two problems in of this sort improved mechanism: the one, the abrasive band loosen with the tensioning course of action in, two ends cylinder action is not exclusively synchronously; The 2nd, the tensioning crossbeam must guarantee enough rigidity, and tensioning section of beam size is bigger, has occupied space, frame central beam cross section, is unfavorable for promoting the use of.
Summary of the invention
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of synchronous tension sander is provided.
For realizing the purpose of this utility model synchronous tension sander, include frame central beam, be connected with main sand roller in the upper end of frame central beam, the lower end of frame central beam is provided with idler roller, sand roller, idler roller are equipped with endless abrasive belt outward, wherein: the lower end of described frame central beam is provided with tensioning cylinder, and the piston rod end of tensioning cylinder connects idler roller, and also is provided with the abrasive band deviation correction mechanism on the piston rod end of tensioning cylinder.
Further, above-mentioned synchronous tension sander, wherein, described tensioning cylinder has two at least, be installed in the both sides of frame central beam lower end respectively, the two ends of described idler roller are equipped with bearing block, and bearing block links to each other with the piston rod end of corresponding tensioning cylinder.
Further, above-mentioned synchronous tension sander wherein, is connected with lazy-tongs between described two tensioning cylinders.
Further, above-mentioned synchronous tension sander, wherein, described lazy-tongs are rack and pinion, both are meshing with each other.
Further, above-mentioned synchronous tension sander, wherein, described abrasive band deviation correction mechanism comprises coupling seat, guide rail, idler roller bearing block, coupling seat is fixedlyed connected with the cylinder piston rod termination, and the coupling seat both sides are equipped with guide rail, is fixed with the idler roller bearing block on the guide rail.
Again further, above-mentioned synchronous tension sander, wherein, described guide rail is double cylindrical linear guide rail.
The utility model has solved two ends, large format sander abrasive band and has realized problem even, synchronous tension by the cooperation of tensioning cylinder, abrasive band deviation correction mechanism.Especially,, can effectively solve asynchronous, the uneven problem of its tensioning, be worth applying in the art for large format sander more than six feet.
The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
