Abstract
The invention discloses a saw blade fixing structure of wood working machinery, which belongs to the technical field of machinery. The saw blade fixing structure comprises a screwing seat, regulating screw rods, sleeve rings, saw blades, a rotating shaft, an inner screw hole, regulating screw holes, a spring I and a spring II, wherein the inner screw hole is arranged at the center of the screwing seat, the regulating screw holes are arranged surrounding the inner screw hole and are penetrated, the regulating screw rods are screwed in the regulating screw holes, the sleeve rings and the saw blades are respectively sleeved on the rotating shaft, the saw blades are positioned between two sleeve rings, the inner screw hole of the screwing seat is locked with a screwing part of the rotating shaft, and the spring I and the spring II are respectively sleeved on the rotating shaft and are positioned between the screwing seat and the sleeve rings. The saw blade fixing structure disclosed by the invention has the beneficial effects that due to the strong elastic force of rotating compression springs, the displacement in short distance can be filled, the clamping force of the sleeve rings can be enhanced, thus the cutting error can be further reduced, and the service life of the saw blades can be prolonged; and in addition, the saw blade fixing structure is provided with two rotating compression springs, a redundant structure is formed, and thus the accuracy of the saw blade fixing structure during the wood cutting is better ensured.
Description
Technical field
The present invention relates to a kind of fixed structure of woodworking machinery, specifically a kind of saw blade fixed structure of woodworking machinery belongs to field of mechanical technique.
Background technology
The employed circular saw blade of traditional circular sawing machine normally is connected to the rotating shaft that is driven by motor, and rotates by the drive of rotating shaft thereupon, and then the ability of performance cutting.In a lot of application, the employed saw blade of above-mentioned circular sawing machine, no matter be single, or the application of multi-disc, the fixing of its saw blade all is to utilize nut to be locked on the screw part of rotating shaft, and utilize the lock of nut to compel and the strength of generation clamping saw blade, yet this fixed form is when implementing, following main disappearance often occurs: 1. the rotating shaft diameter of large-scale woodworking machinery is larger, relative nut size is also larger, and when sealed, this nut must be with large-scale spanner turn packing, under the screwing of powerful torsion, although saw blade has been locked, also cause a day rear nut to deviate from difficulty, cause maintenance, or adjust greatly inconvenience and puzzlement.This saw blade system revolves with nut and is locked on the rotating shaft, and the problem of the vertical precision misalignment of saw blade easily occurs during fixed lock, when making its cutting workpiece the scale error quantitative change large, even affect saw life.
For fear of above-mentioned disappearance, someone is at the adjustment screw that a periphery is provided with some perforations that screws togather of this device, adjusting screw can screw in for an adjustment screw rod, is the turn that can borrow general hand-held tool and adjust screw rod, can screw togather to move in adjusting screw and adjust screw rod; Screw togather whereby seat and can be located at for spiral shell the screw part of rotating shaft, produce a chucking power to utilize the protrusion of adjusting screw rod to support, thereby avoided the trouble with large-scale spanner turn packing, yet still there is lower column defects in this device after the improvement: 1. because long and violent rotatablely moving, adjust screw rod and screw togather the displacement that seat is used small distance, if not often maintenance is difficult to find, thereby cause the decline of accuracy; 2. if often screw tight maintenance, can cause the stripped thread of screw again, thereby it is too fast to cause device to damage.
Summary of the invention
For the problem that above-mentioned prior art exists, the invention provides a kind of saw blade fixed structure of woodworking machinery, do not need often to screw tight maintenance, can guarantee the precision that saw blade is vertical.
To achieve these goals, the technical solution used in the present invention is: a kind of saw blade fixed structure of woodworking machinery, comprise screwing togather seat, and adjust screw rod, the collar, saw blade, rotating shaft, be located at the inner bolt hole that screws togather seat central authorities, be located at the adjustment screw that connects around the inner bolt hole, also comprise spring one and spring two; Adjusting screw rod screws in adjusting screw, the collar and saw blade overlap respectively as on the rotating shaft, and saw blade is between two collars, and the inner bolt hole that screws togather seat is locked on the screw part of rotating shaft, spring one and spring two overlap respectively as on the rotating shaft, and are screwing togather between seat and the collar; Spring one and spring two are spiral compression springs, and spring one is greater than the diameter of spring two, and two springs consist of redundancy structures.
The invention has the beneficial effects as follows: because the powerful elastic force of rotary compression spring itself, can fill up the displacement of small distance, strengthen the chucking power of the collar, thereby and then reduce and cut error, prolong the service life of saw blade, the present invention is provided with two rotary compression springs in addition, consists of redundancy structure, thereby has better ensured the accurate accuracy of the present invention when the cutting wooden unit.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present invention
Fig. 2 is local structural graph of the present invention
Among the figure: 1, the collar, 2, saw blade, 3, spring one, 4, spring two, 5, screw togather seat, 6, rotating shaft, 7, adjust screw rod, 8, adjust screw, 9, inner bolt hole.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of saw blade fixed structure of woodworking machinery comprises screwing togather seat 5, adjusts screw rod 7, the collar 1, saw blade 2, rotating shaft 6, be located at the inner bolt hole 9 that screws togather seat 5 central authorities, be located at the adjustment screw 8 that connects around the inner bolt hole 9, also comprise spring 1 and spring 24; Adjusting screw rod 7 screws in adjusting screw 8, the collar 1 and saw blade 2 overlap respectively as on the rotating shaft 6, and saw blade 2 is between two collars 1, the inner bolt hole 9 that screws togather seat 5 is locked on the screw part of rotating shaft 6, spring 1 and spring 24 overlap respectively as on the rotating shaft 6, and are screwing togather between seat 5 and the collar 1; Spring 1 and spring 24 are spiral compression springs, and spring 1 is greater than the diameter of spring 24, and two springs consist of redundancy structures.
The course of work: spring 1 and spring 24 are nested with at the collar 1 and screw togather between the seat 5, have increased the chucking power between the collar 1, thereby guarantee the precision of saw blade perpendicular cuts; Even little displacement is arranged in use, spring 1 and spring 24 also can because of powerful elastic force itself, be filled up mobile distance, guarantee the chucking power between the collar 1, make saw blade keep best perpendicularity, and then reduce cutting error, the person in service life who prolongs its saw blade.
