Example (b):

referring to fig. 1-4, the utility model provides an adjusting clamp of a vertical shaft circular truncated cone surface grinding machine for bearing machining, which comprises a first clamping block 1 and a second clamping block 2, wherein the first clamping block 1 and the second clamping block 2 are both conical, the first clamping block 1 is driven to operate by a driving piece 3, and the second clamping block 2 is connected with a telescopic mechanism 4;

in this embodiment, first clamp splice 1 and second clamp splice 2 are the taper block, and the two interact can realize the clamp of bearing inner race to possess higher suitability to the size of bearing inner race, hold pressure cylinder is selected for use to telescopic machanism 4, and the cylinder passes through hydraulic system control operation, and this is prior art means, does not need detailed description here.

The first clamping block 1 and the second clamping block 2 are both connected with a sliding block 5 in a sliding mode, and the sliding block 5 arranged on the first clamping block 1 and the sliding block 5 arranged on the second clamping block 2 tend to approach each other in a non-clamping state;

in the embodiment, the axes of the first clamping block 1 and the second clamping block 2 are coincident and vertical;

the use requirement that the sliding blocks 5 are close to each other in a free state can be realized by arranging a spring, in the embodiment, the sliding block 5 on the upper first clamping block 1 can automatically close to the second clamping block 2 under the action of gravity, and the sliding block 5 on the lower second clamping block 2 provides upward sliding acting force through the spring, as shown in fig. 1 and 4.

The sliding block 5 comprises a plane part 51 and a bayonet 52 arranged on the plane part 51, the intersection angle between the bayonet 52 and the plane part 51 is 90 degrees, and at least three sliding blocks 5 are arranged on the first clamping block 1 and the second clamping block 2.

When carrying out the centre gripping of bearing inner race, place the bearing inner race back between first clamp splice 1 and second clamp splice 2, through the extension of control telescopic machanism 4, drive second clamp splice 2 and go upward, then the upper and lower terminal surface of bearing inner race all contacts with the plane portion 51 on the slider 5, and bayonet lock 52 is located the inside of bearing inner race, along with being located keeping away from each other of slider 5 on first clamp splice 1 and the second clamp splice 2, bayonet lock 52 is final with the bearing inner race tensioning, plane portion 51 also contacts with the upper and lower terminal surface of bearing inner race simultaneously, so, after the bearing inner race presss from both sides tightly, slider 5 is great with its area of contact, consequently, contact stress has been reduced.
