Distending groove provided with some separated bulges, each distending groove are uniformly distributed around the center of bulge, and bulge, which is provided with, to be adjusted
The adjusting part of bulge radial direction distending size is saved, adjusting part includes the support ball in each distending groove intersection and some adopted
With being threadedly coupled and be evenly distributed on the screw of bulge, the head of each screw contacts support ball, the axis of each screw to
Outer incline is in the axis of clamping screw.
As the improvement of such scheme, bulge is provided with two distending grooves, and dilation is collinearly by two distending grooves
Upper and lower both sides, bulge are each provided with a screw in upper and lower both sides.
As the improvement of such scheme, a screw is fixedly installed in bulge, and another screw can revolve on bulge
Modulation section.
As the improvement of such scheme, fixed screw uses trip bolt, and the screw of rotatable regulation is adjusting screw.
As the improvement of such scheme, support ball is steel ball.
As the improvement of such scheme, the length of each distending groove is between the 1/3~2/3 of clamping screw total length.
The beneficial effects of the utility model：In this saw blade locking device, the side of clamping screw and traditional nut
Similar, the gap between first preliminary manual locking saw blade, each part of elimination, then the bulge of opposite side is swollen by adjusting part
Open make clamping screw by compress inclined-plane transfer the pressure to flange, so as to be finally reached locking saw blade purpose.Assembling
Cheng Zhong, each screw produce opposition to support ball as fulcrum dilating expansion portion, and the opposition is respectively vertical
Direction and horizontal direction produce component, and the component of wherein horizontal direction makes to generate corresponding screw thread between threaded portion and mandrel pre-
Clamp force, locking so as to have the function that to compress saw blade, thus the design safety performance is high；After unclamping each screw, it can tear open manually
Unload, it is easy to use.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the use state figure of locking device；
Fig. 2 is locking device Force principle figure.
Embodiment
Reference picture 1, Fig. 2, the utility model are a kind of saw blade locking device, including clamping screw.Clamping screw side is
The threaded portion 10 of mandrel 1 is detachably connected, clamping screw opposite side is the bulge 7 of supported flange 3, and bulge 7 is provided with and method
The compression inclined-planes 9 of the contact of orchid 3, clamping screw are surrounded being axially arranged with the distending grooves 6 of some separated bulges 7, each distending groove 6
The center of bulge 7 is uniformly distributed, and bulge 7 is provided with the adjusting part of the regulation radial direction distending size of bulge 7.Adjusting part
The screw of bulge 7 is threadedly coupled and is evenly distributed on including the support ball 5 in each intersection of distending groove 6 and some use,
The head of each screw contacts support ball 5.The outward-dipping axis in clamping screw of the axis of each screw.On the basis of Fig. 2,
Each screw is tilted to the right.
The use state of the locking device is sequentially provided with saw blade 2, flange 3 and clamping screw referring in particular to Fig. 1 on mandrel 1,
Mandrel 1 and the surrounding of flange 3 are equipped with the edge of a wing for being bonded and clamping saw blade 2 jointly.Flange 3 is provided with circle in the side towards saw blade 2
Groove, mandrel 1, which is embedded in the circular groove but does not contact the bottom of circular groove, avoided positioning.
In this saw blade locking device, the side of clamping screw is similar with traditional nut, first preliminary manual locking saw
Piece 2, gap between each part is eliminated, then the bulge 7 of opposite side makes clamping screw pass through pressure by adjusting part distending
Tight inclined-plane 9 transfers the pressure to flange 3, so as to being finally reached the purpose of locking saw blade 2.In an assembling process, each screw is to prop up
Support ball 5 is fulcrum dilating expansion portion 7, while produces opposition, is represented with F, the opposition is respectively in vertical direction
Component is produced with horizontal direction, corresponds to F1 and F2 respectively, the component of wherein horizontal direction makes to produce between threaded portion 10 and mandrel 1
Corresponding threaded pre-tightening power, locking so as to have the function that to compress saw blade 2, thus the design safety performance is high；Unclamp each
