Description
Technical field
The apparatus field that the present invention relates to band sawing machine and need tensioning and quick-release structure for annular transmission, specifically a kind of circular band saw device of capable of adjusting tensioning power.
Background technology
In band sawing machine application, bands for band transmission is all to drive band saw blade shuttling movement by driving wheel and driven pulley, in order to guarantee the stability of saw blade cutting and to prevent that the factors such as saw blade cutting process sudden change from causing damage to saw blade, the saw blade tension adjusting and the quick-release replacing bands for band that therefore connect driving wheel and driven pulley are just even more important.The driving wheel of common sawing machine and driven pulley are all distributed in with it holistic rigid bed, and saw wheel holder size is larger, and strainer is easily arranged, and tensile force regulates and quick-release two cover governor motions are separate.
Sawing machine for cantilever mechanism, in order to alleviate cantilever force, guarantee sawing quality, the bulk of the driven saw wheel standing part of cantilever end is all very tightly short, existing tensioning and quick-release structure can not realize substantially, therefore develop a kind of novel circular band saw tensile force adjusting and Quick-disassembling device very necessary.
Summary of the invention
The object of the present invention is to provide a kind of circular band saw device, can effectively solve saw blade tension adjusting and quick-release mechanism in the reasonable Arrangement of cantilever sawing machine position, alleviate cantilever force, realize saw blade tension and regulate and quick-release.
A kind of circular band saw device, contain circular saw blade and body, circular saw blade is connected on driving wheel and driven pulley, driving wheel and driven pulley are fixed on body, it is characterized in that described driven pulley is fixed on body by a tension structure and a quick-release structure, described tension structure is a slidably assembly, tension structure is embedded in the first chute of body, this tension structure is by tensioning slide block, stage clip, tensioning shaft and tensioning pull bar form, tensioning shaft can slide on the slideway of tensioning slide block, the wheel shaft of this tensioning shaft and driven pulley is structure as a whole, the front end of tensioning pull bar is through the through hole of tensioning shaft, and be embedded with stage clip at the front end of tensioning pull bar, the other end of tensioning pull bar is screwed onto a side of tensioning slide block, described quick-release structure is a slidably assembly equally, and quick-release structure is embedded in the second chute of body, and this quick-release structure is comprised of quick-release slide block and the eccentric wheel that is embedded in quick-release slide block inner chamber, between the tensioning slide block of described tension structure and the quick-release slide block of quick-release structure, by a connecting rod, fix.
During use, when needs regulate saw blade tension, rotate tensioning pull bar, between tensioning pull bar and tensioning shaft, screw connection structure produces pushes away or pulling force and stage clip form one group of equilibrant force, push-and-pull tensioning shaft moves in tensioning slide block, and the sawing external force while guaranteeing saw blade work changes the equilibrant force producing with tensile force mechanism and mutually mates; When Fast Installation and dismounting saw blade, rotating eccentric wheel shaft drives quick-release slide block along body the second runner movement, due to eccentric eccentric center principle, the tensioning slide block mass motion that is dynamically connected of quick-release slide block band, tensioning shaft drives driven saw wheel motion simultaneously, distance between two saw wheels that make increases or shortens, reach the effect of Fast Installation and dismounting, because the auto-lock function of eccentric wheel when extreme position, so saw blade is under processing tensioning state, it is not lax that the equilibrant force that strainer produces can meet saw blade processing tensile force.
Beneficial effect of the present invention is, by the isostructural reasonable utilization of eccentric mechanism principle, screw thread push-pull principle and stage clip equilibrant force, has realized tensioning, fine setting and the quick-release of saw blade in tight short space.Have simple in structure, easy to use, cost is low and efficiency high.
Below in conjunction with embodiment accompanying drawing, the application is described in further detail:

The specific embodiment
Referring to accompanying drawing, accompanying drawing has omitted the overall structure of band saw device, and emphasis has been shown tensioning and the quick-release structure of distinguishing characteristics part band saw of the present invention.A kind of circular band saw device, contain circular saw blade and body 1, circular saw blade is connected on driving wheel and driven pulley, and driving wheel and driven pulley are fixed on body 1, it is characterized in that described driven pulley is fixed on body by a tension structure and a quick-release structure.
Wherein: tension structure integral body is a slidably assembly, tension structure is embedded in the first chute 2 of lathe bed body 1, this tension structure is by tensioning slide block 7, stage clip 6, tensioning shaft 8 and tensioning pull bar 9 form, tensioning slide block 7 is embedded in the slideway of the first chute 2, tensioning shaft 8 is embedded in the inner slide of tensioning slide block 7 and can on the inner slide of tensioning slide block 7, slides, this tensioning shaft 8 is structure as a whole with the wheel shaft of driven pulley, one end of tensioning pull bar 9 is through the through hole of tensioning shaft 8, stage clip 6 is embedded between the front end and through hole of tensioning pull bar 9, the other end of tensioning pull bar 9 is fixed on a side of tensioning slide block 7, because tensioning pull bar 9 is the form of being threaded with tensioning slide block 7, therefore rotate tensioning pull bar or saw blade tension while changing, stage clip 6 can be along with the stressed variation in outside is adjusted automatically, and drive tensioning shaft (follower shaft) to seesaw.
Described quick-release structure is a slidably assembly equally, by a connecting rod 10, quick-release structure and tension structure are connected to a Coupled motion part, quick-release structure is embedded in the second chute 5 of lathe bed body 1, this quick-release structure is comprised of quick-release slide block 3 and the camshaft 4 that is embedded in quick-release slide block inner chamber, camshaft 4 external diameters are tangent with quick-release slide block 3 inner chambers all the time simultaneously, guarantee that in camshaft 4 rotation processes, quick-release slide block 3 can move along the second chute 5, eccentric center principle due to cam, rotating camshaft 4 can drive tensioning slide block 3 to move along body the first chute 2 by quick-release slide block 3 and connecting rod 10, and produce two limit machinery dead-centre positions, guarantee that tensioning changes the stability of saw blade.
When needs regulate saw blade tension, rotate tensioning pull bar 9, what between tensioning pull bar 9 and tensioning shaft 8, screw connection structure produced pushes away or pulling force and one group of equilibrant force of stage clip 6 formation, push-and-pull tensioning shaft 8 moves in the inner slide of tensioning slide block 7, and the sawing external force while guaranteeing bands for band work changes the equilibrant force producing with tensile force mechanism and mutually mates, when Fast Installation and dismounting saw blade, rotate the eccentric shaft of camshaft 4, drive quick-release slide block 3 to move along body the second chute 5, eccentric center principle due to cam, quick-release slide block 3 drives 7 mass motions of tensioning slide block by connecting rod 10, simultaneously because tensioning shaft 8 and follower shaft are structure as a whole, thereby drive driven saw wheel motion, distance between two saw wheels that make increases or shortens, reach the object of Fast Installation and dismounting, because the auto-lock function of camshaft when extreme position, so saw blade is under tensioning state, it is not lax that the equilibrant force that strainer produces can meet saw blade processing tensile force.
