Detailed description of the invention
Below in conjunction with the accompanying drawings and the technical scheme in this utility model is further illustrated by embodiment.
As shown in figures 1 to 6, including driving axle housing 1, cross elastic slide block 2, driven shaft sleeve 3, clamping device 4, top 5, V
Type props up bracer 6, and described driving axle housing 1, cross elastic slide block 2, driven shaft sleeve 3 are mutually matched connection successively, driving axle housing 1,
Driven shaft sleeve 3 phase is internally provided with the mounting groove that shape size is identical, and direction is 90 ° and is interspersed, cross elastic slide block 2 liang
Outer surface is provided with the projection that shape size is identical with mounting groove, and direction is 90 ° and is interspersed；Driving axle housing 1 is away from cross bullet
Property slide block 2 one end is connected with grinding machine output shaft, and driven shaft sleeve 3 is provided with clamping device and top away from cross elastic slide block 2 one end
Point.As shown in Figure 4, described driving axle housing 1 is uniformly provided with the same number of through hole, by bolt spiral shell with driven shaft sleeve 3 end face
It is overall that driving axle housing 1, cross elastic slide block 2 and driven shaft sleeve 3 are connected as one by mother.
Such as Fig. 1, the clamping device 4 shown in 4, including two elastic supporting bars 7 with hold out against cam 8, be respectively fixedly disposed at relatively
On each limit intersection point of the vertical equilateral triangle line of top 5 axis centre symmetries, upper position of intersecting point is provided with and holds out against cam 8,
Twice position of intersecting point is respectively equipped with elastic supporting bar 7；Described two elastic supporting bars 7 are connected with bolt 9, and pass through driven shaft
The bolts hole that are provided with of set 3 screw in driven shaft sleeve 3, described in hold out against the cam profile outer surface of cam 8 and be enclosed with elastic component, top
It is fixed in driven shaft sleeve 3 in tight cam 8 holds greatly embedding driven shaft grooving and by rivet 10 riveting, holds out against at cam 8 handle
Being provided with aperture, spring 11 one end is directly connected in aperture, and the other end is then directly anchored to from dead axle set 3 by screw.
During use, collar bush 1 is connected on grinding machine output shaft, the centre bore of one end of axle 12 is alignd with top 5, passes through
Swivel bolt 9 adjusts two elastic supporting bars 7 to after suitable position, presses the handle holding out against cam 8, and spring 11 is compressed,
Axle 12 is loaded driven shaft sleeve 3, contacts with top 4 and unclamp the handle holding out against cam 8, by the bullet being connected with cam 8 after holding out against
The back stretch compression axis 12 of spring 11, the other end of axle 12 is naturally placed on V-type and props up on bracer 6, supports by being arranged on V-type
Elastic cushion block 13 on block 6 socket supports；When grinding machine normally works, cross elastic slide block 2 be positioned at driving axle housing 1 with from
Between moving axis set 2, by time radially sliding in the two corresponding mounting grooves of axle sleeve and slight deformation compensates clamping and operating
The relative displacement of two between centers, and two elastic supporting bars 7 match with the parcel elastomer holding out against cam 8 external edge surface, axle 12
Elastomer can be made to produce deformation in various degree according to the difference of the size of the power being subject on 3 directions thus reach regulation certainly
The purpose of body position, farthest reduces the error brought due to grinding machine output shaft torsional oscillation, after grinding, only needs
Press the handle holding out against cam 8 to be taken out by axle 12, after loading the axle 12 that next part needs grinding, unclamp the handle holding out against cam 8
Hands, hold out against cam 8 by reply at spring 11 coordinate with elastic supporting bar 7 under the effect of the elastic force of deformation realize countershaft 12 folder
Tightly；In addition, by propping up the deformation that the elastic cushion block 13 of bracer 6 socket and the setting of axle 12 contact position produces due to stress in V-type
Compensate the problem solving axle 12 deformation that grinding heat causes.
The non-detailed portion of this utility model is prior art.
Finally illustrating, above example is only in order to illustrate technical scheme and unrestricted, although with reference to the most real
Execute example the present invention has been described in detail, it will be understood by those within the art that, can be to the technical side of the present invention
