the grinding handle 3 is columnar, a conical boss is arranged on the grinding handle 3, and a first end of the grinding handle 3 is provided with a thread; one end of the conical boss close to the first end of the grinding handle 3 is a smaller end;
the opening bushing 2 is sleeved at the first end of the grinding handle 3, the conical surface bushing is sleeved outside the opening bushing 2, and grinding of the conical surface bushing is realized through grinding paste arranged between the opening bushing 2 and the conical surface bushing;
the locking nut 1 is sleeved at the first end of the grinding handle 3 and used for pressing the opening bushing 2 downwards towards the conical boss, so that the opening bushing 2 deforms and is attached to the conical boss and the conical bushing respectively.
Optionally, the inner diameter of the split bush 2 is larger than the outer diameter of the smaller end of the conical boss and not larger than the outer diameter of the larger end of the conical boss.
Optionally, the surface of the split bush 2 contacting the tapered boss is a tapered surface.
Optionally, the material of the split bush 2 is soft metal.
Optionally, the height of the conical boss is greater than the height of the opening bush 2, and the height of the opening bush 2 is greater than the height of the conical bush.
Optionally, the outer diameter of the lock nut 1 is larger than the outer diameter of the split bush 2.
Optionally, the outer circumferential surface of the lock nut 1 is knurled.
Optionally, the outside diameter of the split bush 2 is smaller than the inner bore of the taper bush.
Optionally, the second end of the grinding handle 3 is provided with knurling.
The invention provides a grinding clamp for a conical bushing, which is used for fixing and loosening the conical bushing by manually screwing a locking nut in and out to control the outward expansion degree of an opening bushing. The grinding clamp solves the product quality problem caused by inconvenient disassembly of the traditional grinding clamp; not only ensures the precision of the processing surface, but also improves the processing efficiency.

Detailed Description
The grinding jig for the tapered bushing according to the present invention will be explained with reference to the accompanying drawings.
Referring to fig. 1-3, the present invention provides a grinding jig for a tapered bushing, comprising: lock nut 1, opening bush 2, grinding handle 3.
The grinding handle 3 is provided with a conical boss, the boss is contacted with the opening bush 2, and the inner diameter of the opening bush 2 is larger than the outer diameter of the upper end of the boss and cannot be larger than the outer diameter of the bottom of the boss.
In order to avoid the surface scratch of the conical boss caused by stress concentration, the surface of the opening bush 2 contacted with the conical boss is also set to be a conical surface, and the material of the opening bush 2 is selected from soft metal aluminum alloy.
A stud is arranged on the conical boss of the grinding handle 3 and matched with the locking nut 1, and the outer diameter of the locking nut 1 is required to be larger than that of the opening bush 2.
Optionally, the outer circle surface of the locking nut 1 is knurled to facilitate screwing.
When the split bush 2 is placed on the conical boss and no external force is applied, the upper end surface of the split bush 2 is lower than the upper end surface of the stud, and the height of the split bush 2 cannot be lower than the height of the conical bush contacted with the split bush.
The split bush 2 can be passed through the inner bore of the taper bush.
The use steps of the grinding clamp for the conical surface lining provided by the invention comprise:
s1, sleeving the opening bush 2 on the conical boss, sleeving the conical bush on the opening bush 2, and smearing grinding paste between the conical bush and the opening bush 2;
s2, slowly screwing the locking nut 1 into the stud, enabling the locking nut 1 to be in contact with the opening bush 2 and pressing the opening bush 2 downwards, at the moment, slowly expanding the opening bush 2 outwards, and stopping screwing the locking nut 1 to finish clamping the taper bush when the taper bush and the opening bush 2 are completely attached;
for example, the stud height may be calculated so that the nut is fully seated when screwed onto the bottom end of the stud.
S3, fixing the taper bush, and rotating the grinding handle 3 to grind the taper bush;
it will be appreciated that the taper bush may also be rotated in the opposite direction to the grinding handle 3.
S4, after the two conical surfaces are ground, the locking nut 1 is screwed out, the grinding handle 3 is pulled out to separate the two parts, at the moment, the opening bush 2 is slowly contracted inwards under the influence of the elastic deformation of the soft metal and gradually separated from the inner surface of the conical bush, and the conical bush is taken out after the two parts are completely loosened.
The grinding clamp is simple in structure, easy to manufacture and convenient to operate through practical verification, grinding efficiency is improved, and the quality of a machined surface is guaranteed.
