Description
Technical field
The invention relates to a kind of slidingtype and to cut sth. askew cyclotomy saw, be called for short sliding type mitre saw, particularly a kind of nose assembly can relatively support swing up and down, slide anteroposterior and the sliding type mitre saw that swings.
Background technology
The mitre saw sold in the market can be divided into mitre saw not with pull bar and sliding type mitre saw.Mitre saw not with pull bar can only do head and move up and down and the banking motion of left and right, so after its head presses, the sectional area of cutting material can depend on and the diameter of the saw blade that machine loads namely depend on the specification of machine; And the size of saw blade determines the watt level of motor, generally larger saw blade needs the motor of larger power to support.Sliding type mitre saw increases the cutting power of machine relative to support slide anteroposterior by head, achieve the possibility of small dimension, low power mitre saw cutting large size material.Sliding type mitre saw is by the ability considerably increased on cutting width and height of sliding.
The market share, on current desk type electric tools market, comprise domestic and export trade, the most salable instrument is exactly mitre saw, is widely used in building, house ornamentation, household maintenance, factory's specialty cuts occasion etc.And after sliding type mitre saw occurs, the cost particularly produced with batch continues to reduce, the share of sliding type mitre saw inside whole mitre saw is increasing, what the current non-sliding type mitre saw except some small dimensions was current also has more large batch of production, other is large gauge comparatively, and the mainstream model as more than 210mm specification adopts slidingtype to be main substantially.So be also mainstream model inside the present whole desk type electric tools of sliding type mitre saw.
The slide construction implementation of current 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, and slide bar is motionless, and whole head is along sliding bar.

2. 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, particularly its center square machining accuracy needs within 0.01mm, common milling machine is difficult to the square requirement of guarantee center, relatively unfavorable for cost control.Secondly, the quadrilateral structure intensity produced after two slide bar combinations, has higher requirement to the machining accuracy of the fixture at two ends equally.
3. there is potential safety hazard, the quadrilateral structure of common Slide bar structure may cause the possibility of unexpected tong in drawing process.
4. the linear bearing be used on mitre saw requires lower, and price is lower, but because reasons in structure, cost is still times over the price of common ball bearing; Next bearing registration being precision is low is relatively low, and noise during slip also can be higher, and the high linear bearing cost of precision can rising at double.
5. profile is single, lacks change.
