in the figure, 1 three-jaw chuck, 2 hidden grooves, 3 adjusting bolts, 4 pushing cylinders, 41 inner inclined planes, 42 bending sections, 5 cushion blocks, 51 lower inclined planes, 6 return springs, 7 arc-shaped supporting plates, 8 guide posts, 9 supporting springs and 10 inner cylinders.
Detailed Description
The attached drawings are specific embodiments of the invention. As shown in fig. 1 to 5, the hub fixture tool for the numerical control machining center comprises a circular three-jaw chuck 1, a blind groove 2 is formed in the three-jaw chuck 1, the blind groove 2 is arranged on the diameter of the three-jaw chuck 1 and penetrates through the whole diameter, an adjusting bolt 3 is mounted on the blind groove 2 through a bearing, the adjusting bolt 3 can only rotate in a shaft, the adjusting bolt 3 is in threaded connection with a propelling barrel 4, the propelling barrel 4 is provided with two inner inclined surfaces 41, the two inner inclined surfaces 41 are positioned on two sides of the circle of the three-jaw chuck 1 and face the same direction, a cushion block 5 is arranged above the inner inclined surfaces 41, the cushion block 5 is preferably cylindrical, the lower end of the cushion block 5 is a lower inclined surface 51, the lower inclined surface 51 and the inner inclined surfaces 41 can form a right-angle cushion block, the cushion block 5 extends out of the blind groove 2, a return spring 6 is sleeved on the cushion block 5, one end of the return spring 6 is fixed on the cushion block 5, one end is fixed on the wall of the hidden groove 2; an arc-shaped supporting plate 7 is fixedly arranged at the upper end part of the cushion block 5, so that the supporting area is increased.
The three-jaw chuck 1 at the position of the cushion block 5 is an inner cylinder 10, the inner cylinder 10 is communicated with the blind groove 2, the upper opening of the inner cylinder 10 is matched with the cushion block 5, but the inner cavity is thicker than the cushion block 5 so as to conveniently vacate a space for the return spring 6, and the lower end of the return spring 6 can also be fixed on the inner wall of the inner cylinder 10.
The blind holes are respectively drilled on two sides of the blind groove 2, each blind hole is matched with one guide post 8, the guide posts 8 are fixed on the arc-shaped supporting plate 7, the lower ends of the guide posts 8 are provided with supporting springs 9, and the elastic force of the two supporting springs 9 is smaller than that of the return spring 6.
When the cushion block 5 is at the highest point, the supporting spring 9 is in a free state or a slightly compressed state, the return spring 6 is in a stretched state, when the cushion block 5 moves downwards, the supporting spring 9 is compressed, and the return spring 6 gradually restores to the original state.
In order to increase the lifting height of the cushion block 5, a bending section 42 is arranged between the two inner inclined surfaces 41, and the front and the rear of the bending section 42 are solid sections.
The using process is as follows: the hub flange is placed between the three claws, the adjusting bolt is screwed according to the height of the hub flange, the pushing cylinder 4 is pushed forwards, and the cushion block 5 is pushed upwards until the proper height is reached, namely, when the pushing cylinder 4 moves forwards, the cushion block 5 rises, and when the pushing cylinder 4 moves backwards, the cushion block 5 falls. And after reaching the proper height, the three-jaw clamp is used for clamping and fixing, the arc-shaped supporting plate 7 and the cushion block 5 jointly play a supporting role on the hub flange, and then the hub flange is processed.
