Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the present invention.
With reference to Fig. 1, the fixture being applicable to the grinding of needle-valve tail angle of the present invention, comprise: rotating disk 22, the motor 11 be fixedly connected with by motor fixing plate 24 with rotating disk 22, the bakelite wheel 9 of rotation is driven by motor 11, particular by overlapping on motor pulley 12 and the bakelite wheel 9 of motor 11, an O RunddichtringO 10 carries out transmission to realize, also comprise: the rotating shaft belt pulley 8 that arrange coaxial with bakelite wheel 9, insert the rotating shaft 1 in rotating shaft belt pulley 8 axle center, be fixed on the pinch roller 3 of rotating shaft 1 end, to be enclosed within rotating shaft 1 and bearing 13 between bakelite wheel 9 and pinch roller 3, be enclosed within the support 6 on bearing 13 outer ring, the fork 15 be fixedly connected with support 6, and be positioned at below pinch roller 3 for placing the V-block 20 of needle-valve, the rotating shaft of pinch roller 3 is arranged in the mode tilted relative to horizontal direction, the V-block 20 placing needle-valve is horizontally disposed with, thus can realize going out certain angle in the grinding of needle-valve afterbody.Wherein, the inside of support 6 is formed with the cavity of accommodation rotating shaft 1 and bearing 13 and the outer wall of support 6 is formed with long handle, fork 15 cylindrically and its outer wall is also formed with long handle, support 6 and fork 15 be fixedly connected be by the long handle of the two between be fixedly connected with and realize, preferably with bolts, the side of V-block 20 is provided with the jacking block 19 of the front end for withstanding needle-valve, the below of V-block 20 is provided with the fixed block 21 be fixedly connected with rotating disk 22, the sidewall of fixed block 21 is connected with thread spindle 16, fork 15 to be enclosed within thread spindle 16 and can to rotate around thread spindle 16, when fork 15 is after thread spindle 16 rotates certain angular distance, because support 6 is fixedly connected with fork 15, therefore support 6 also rotates identical angular distance, and pinch roller 3 is now static relative to support 6, so pinch roller 3 also moves identical angular distance, show as pinch roller 3 spatially to move along arc trajectory, the result of movement is that pinch roller 3 is lifted, no longer be pressed on V-block 20, now needle-valve can be put into V-block 20.Before processing, need the goniometer of processing to calculate the angle of rotating disk 22 needs processing by needle-valve, then turn corresponding angle according to the scale on rotating disk 22, finally with screw, rotating disk 22 is fixed on base 23.
Conveniently rotational swing rod 15, as the preferred scheme of one, support 6 is welded with handlebar 14.Weld on the frame 6 by handlebar 14, the arm of force of this position can reach maximum, therefore can be the most laborsaving.
Conveniently regulate the angle that the rotating shaft of pinch roller 3 tilts relative to horizontal direction, as the preferred scheme of one, fixture of the present invention also comprises: guide pad 17.Guide pad 17 is in wedge shape, uneven both sides vis-a-vis contact with the long handle of fork 15 with the long handle of support 6 respectively and are fixedly connected with, by changing the guide pad 17 with different angle, can regulate the angle that the rotating shaft of pinch roller 3 tilts relative to horizontal direction easily, and the adjustment of angle is not only accurate but also quick.
As the preferred scheme of one, fixture of the present invention also comprises: pedestal 18.Pedestal 18 is fixed on the side of V-block 20, and jacking block 19 is fixedly connected with V-block 20 by pedestal 18.
More preferably, pedestal 18 adjustable in length in the horizontal direction, and then the length that can control that needle-valve afterbody leans out V-block 20 easily, thus adjust its stock removal, effectively control the size of the length direction of workpiece.
Jacking block 19 is for withstanding the paracone of needle-valve, needle-valve in the process of grinding is avoided to affect the grinding of angle to paracone direction play, in order to effectively prevent the wearing and tearing of jacking block 19, ensure the precision of processing, as the preferred scheme of one, the face contacted with needle-valve of jacking block 19 is provided with hard alloy abrasion-resistant layer.
In the present invention, the front and rear sides of pinch roller 3 is also separately installed with front plate 4 and rear plate 2, for protecting pinch roller 3.In addition, between front plate 4 and support 6, be also provided with dottle pin 5, for reducing collision therebetween.In addition, support 6 is also provided with bearing cap 7 in the one end towards rotating shaft belt pulley 8, for preventing the part clashing and breaking bearing 13 of the projection of rotating shaft belt pulley 8.
In fixture of the present invention, support 6 is also fixed with stay bolt 25.Needle-valve to be placed on V-block 20 and after being pushed down by pinch roller 3, stay bolt 25 is hung an elastic belt (not shown), and this elastic belt is connected with lathe tightens, now pinch roller 3 is impaction state, and the large cylindrical of the needle-valve on V-block 20 pushed down comparatively closely by pinch roller 3.Now, under the drive of motor 11, by through-drive, pinch roller 3 rotates around the rotating shaft of self, and then the needle-valve body driving pinch roller 3 to push down rotates, thus grinding angle.
By repeatedly processing and measuring, the needle-valve tail angle size conforms standard utilizing fixture of the present invention to process, ensure that accuracy and the following process positioning datum of processing, and is easy to employee's operation, shortens working time, substantially increases efficiency.
It should be noted that, above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
