By means of the technical scheme, the pushing plate 1, the sliding block 4, the limiting block 5, the mounting seat 6 and the hook head pressing plate 7 are matched, so that the limiting block 5 is driven by the pushing plate 1 to move left and right on the outer side of the fixture body 3, the limiting block 5 drives the hook head pressing plate 7 to do circular motion, parts placed between the hook head pressing plate 7 and the mounting seat 6 can be fixed, further, the numerical control lathe can realize semi-braking production for processing spherical inner holes of parts, the efficiency for processing the spherical inner holes of the planet gears is greatly improved, meanwhile, the production cost for processing the spherical inner holes of the planet gears is also reduced, the quality reliability after the spherical inner holes of the planet gears are finished is also greatly improved, in addition, when the inner holes are processed for parts of different types, the mounting seat 6 and the hook head pressing plate 7 of the device only need to be replaced by a model matched with the parts to be processed, therefore, the structure of the invention is simpler, and all parts are better matched, thereby facilitating the replacement of the hook head pressing plate 7 and the mounting seat 6 when workers process inner holes of parts of different types.

In one example, for the above-described push plate 1, the push plate 1 is connected to the pull rod 14 by a screw 15.

By means of the above-mentioned technical scheme, be connected slurcam 1 and pull rod 14 through setting up screw 15, thereby the inside of the anchor clamps body 3 sets up with the spacing chamber of slurcam 1 matched with, also be provided with simultaneously with the spacing chamber of screw 15 matched with, make pull rod 14 drive screw 15 and slurcam 1 carry out the removal in position about the spacing intracavity of the inside of the anchor clamps body 3, make slurcam 1 drive slider 4 and stopper 5 carry out the removal in position about, stopper 5 cooperatees with eave tile clamp plate 7, stopper 5 drives eave tile clamp plate 7 and carries out the motion of circumference, and then can carry out better fixed to the part of putting into between mount pad 6 and the eave tile clamp plate.

In one example, for the above-mentioned push plate 1, the push plate 1 is connected with the sliding block 4 by a screw two 2.

By means of the above technical scheme, be connected slurcam 1 and slider 4 through setting up screw two 2 to make slurcam 1 when carrying out the removal in the position about spacing intracavity in the anchor clamps body 3, can make slider 4 drive stopper 5 carry out the removal in position about, and then make the wedge-shaped surface of stopper 5 cooperate with the wedge-shaped surface of eave tile clamp plate 7, thereby make stopper 5 drive eave tile clamp plate 7 carry out circular motion, and then make the device's structure although simple be convenient for to the fixed of part and processing.

In one example, for the above-described mounting seat 6, the mounting seat 6 is connected with the clamp body 3 by a screw three 10.

By means of the technical scheme, the mounting seat 6 is connected with the clamp body 3 through the third screw 10, so that the fixing mode between the clamp body 3 and the mounting seat 6 is more simple, convenient and effective, when the inner holes of different parts are machined, the third screw can be disassembled, then the mounting seat 6 is replaced according to the models of the parts with the same type and different models, and the parts can be machined by the inner holes, so that the use of workers is facilitated.

In one example, for the hook head pressing plate 7, the hook head pressing plate 7 is connected with the mounting seat 6 through a fixing shaft 11.

With the help of the technical scheme, the mounting seat 6 and the hook head pressing plate 7 are connected through the fixed shaft 11, so that when the limiting block 5 is matched with the hook head pressing plate 7 to process an inner hole of a part, the hook head pressing plate 7 is matched with the fixed shaft 11 to enable the hook head pressing plate 7 to move circumferentially, and the hook head pressing plate 7 is matched with the spring 8 and the limiting block 5 to well fix the part placed between the mounting seat 6 and the hook head pressing plate 7.

In one example, for the above-mentioned fixed shaft 11, a washer 12 is provided at one end of the fixed shaft 11, and a screw four 13 is inserted into the washer 12 to match with the washer.

By means of the above technical scheme, gasket 12 has been seted up through one side at fixed axle 11, thereby set up screw four 13 in making the gasket, make fixed axle 11 more firm under the cooperation of screw four 13 and gasket 12, and then make and cooperate between stopper 5 and the eave tile clamp plate 7 and fix the time convenience more to the part, through set up screw four 13 rather than matched with in gasket 12, thereby make screw four 13 with the stable outside of fixing at mount pad 6 of fixed axle 11, make stopper 5 remove about going on, cooperate with spring 8 and drive eave tile clamp plate 7 when carrying out the circular motion, eave tile clamp plate 7 is under the cooperation of fixed axle 11 and screw four 13, circular motion can be carried out steadily, and then can carry out better fixing to the part of placing between mount pad 6 and eave tile clamp plate 7.

In an example, for the above limiting block 5, the limiting block 5 is matched with the hook head pressing plate 7, and both the outer side of the limiting block 5 close to the hook head pressing plate 7 and the inner side of the hook head pressing plate 7 close to the limiting block 5 are in a wedge shape.

With the help of the technical scheme, the wedge-shaped surface is arranged on the outer side of the limiting block 5 and the wedge-shaped surface is arranged on the inner side of the hook head pressing plate 7, so that the limiting block 5 is better matched with the hook head pressing plate 7, when the limiting block 5 moves leftwards, the wedge-shaped surface of the limiting block 5 is matched with the wedge-shaped surface of the hook head pressing plate 7, parts placed between the hook head pressing plate 7 are well fixed, and then the use of workers is facilitated.

In one example, for the stopper 5, the stopper 5 has a convex-like shape.

With the aid of the technical scheme, the limiting block 5 is set to be in a convex shape, so that the limiting block is convenient to be matched with the hook head pressing plate 7 better, the limiting block 5 is made to move left and right on the outer side of the clamp body 3, the wedge face of the limiting block 5 is matched with the wedge face of the hook head pressing plate 7, and parts can be well fixed.

The working principle is as follows: during the use, pull rod 14 drives catch plate 1 and screw 15 and moves to the left side, thereby make catch plate 1 drive screw two 2 and slider 4 and move left, can make slider 4 drive stopper 5 and move left side mutually, and then make stopper 5 and eave tile clamp plate 7 separate, spring 8 is inboard to reset, drive eave tile clamp plate 7 and do the circular motion, can put into the mount pad 6 with unprocessed part this moment, make pull rod 14 move to the right side, thereby drive catch plate 1, screw two 2 and slider 4 move to the right side, make the slider drive stopper 5 and move to the right side, cooperate with eave tile clamp plate 7, and then make eave tile clamp plate 7 drive spring 8 and stretch, fix the part of placing between eave tile clamp plate 7.

in summary, according to the above technical scheme of the present invention, the mounting base 6 and the hook head pressing plate 7 are matched, so that when the device processes parts of the same type, the mounting base 6 and the hook head pressing plate 7 can be directly replaced to process the parts of the same type, which is convenient for a worker to use, and the limiting block 5 is matched with the hook head pressing plate 7, so that the limiting block 5 moves around the outer side of the clamp body to drive the hook head pressing plate to perform a circular motion, and fixes the parts placed between the mounting base 6 and the hook head pressing plate 7, which is convenient for the worker to operate and simultaneously stabilize the placement of the parts.
