Background technology
The sliding type mitre saw sold in the market increases the cutting power of machine relative to turntable slide anteroposterior by head cutting assembly, achieve the possibility of small dimension, low power mitre saw cutting large size material, by the ability considerably increased on cutting width and height of sliding.The slide construction implementation of existing mitre saw is mainly based on slide bar type structure, and namely two slide bars carry out slidably reciprocating of rectilinear direction by the linear bearing be arranged on rocking arm.The mounting means of slide bar can be divided into three kinds: a kind of top being mounted in support, the rear side of head; The second is mounted in below support; The third mode is that linear bearing is arranged on head cutting assembly, and slide bar is motionless, and whole head cutting assembly is along sliding bar.Although various slide bar form forms are in sum varied, its principle is the same, is all by slide bar linear slide realization back and forth on linear bearing.
But there is following problem in existing sliding type mitre saw: one is that the technical property requirements of slide bar is high, because slide bar and the steel ball of linear bearing inside directly contact i.e. point cantact, so, larger pressure can be born in the local, surface of slide bar, as used common steel, surface can produce gravure and scratch, thus reduces the surface quality of slide bar, affects smoothness and outward appearance.Two is that slide bar belongs to appearance parts, to corrosion-resistant and antirust require high, slide bar processed complex, cause cost higher, due to two whole head cutting assemblies of slide bar cantilever support, in order to ensure the precision and stability of complete machine, there is higher requirement to the rigidity of slide bar.Three is that installation accuracy is high, two slide bars be mounted opposite precision and the relative accuracy of linear bearing that coordinates with it needs coupling, otherwise have influence on the smooth degree of complete machine, common milling machine is difficult to ensure slide bar machining accuracy.Four is there is potential safety hazard, and the quadrilateral structure of common Slide bar structure may cause the possibility of unexpected tong in drawing process.Five is that profile is single, lacks change.
For the problems referred to above that existing sliding type mitre saw exists, many manufacturers and knowledgeable people are studied and develop, but not yet have more rational product to emerge so far.
Summary of the invention
For overcoming the problems referred to above that existing sliding type mitre saw exists, the purpose of this utility model is to provide that a kind of simple and reasonable, production and processing is convenient, quality of fit requirement is low, structural strength is high, the obform guide rail carriage of bending resistance and flexural capacity is good, production cost is low, elegant in appearance sliding type mitre saw.
The utility model solves the technical scheme that its technical problem adopts, it comprises the rocking arm be arranged on turntable, guide rod, the two ends correspondence of guide rod is fixed with guide rod back seat and head Connection Block, described guide rod is provided with the line slide rail of the distribution that assumes diamond in shape, described rocking arm is provided with U-lag mouth, U-lag mouth bilateral symmetry is provided with inwardly protruded triangle or trapezium structure, the upper plane of both sides triangle or trapezium structure is provided with at least two group upper bearing (metal)s by tensioning governor motion correspondence, the lower plane of both sides triangle or trapezium structure is provided with at least two group lower bearings by lower central shaft correspondence, upper bearing (metal) on both sides triangle or trapezium structure and lower bearing are rollably arranged on the line slide rail of rhombus distribution.
The utility model is scheme further, described tensioning governor motion comprises sliding shoe, central screw, adjustment screw, locking nut, one end of sliding shoe is hinged on by central screw in the upper plane of triangle or trapezium structure, upper bearing (metal) is arranged on the other end of sliding shoe rotationally by upper central shaft, and adjustment screw is arranged on U-lag mouth top by locking nut and top is pressed on sliding shoe.
The utility model is scheme further, and described guide rod is hollow structure, hollow structure is distributed with some reinforcements, and is made up of aluminum alloy materials, and described line slide rail is made up of hard wear-resistant material.
The utility model is scheme further, and the U-lag mouth of described rocking arm is provided with cover plate.
After adopting said structure, there are following advantage and effect compared with the prior art: one is because the upper bearing (metal) on both sides triangle or trapezium structure and lower bearing are rollably arranged on the line slide rail of rhombus distribution, guide rod slide anteroposterior is light flexibly, good stability, assembly precision requires low, wear and tear little, noise is low, long service life.Two is the gaps due to adjustment screw and locking nut and sliding shoe adjustment upper bearing (metal) and line slide rail, can ensure smooth degree, greatly can reduce the machining accuracy of each parts, thus ensure lasting precision while guarantee assembly precision.Three is that hollow structure is distributed with some reinforcements, structural strength is high because guide rod is hollow structure, bending resistance and anti-twisting property good, difformity can be designed to coordinate different machine shape requirements.
