In order to solve the technical problem, the utility model discloses a technical scheme is:
the utility model provides an aluminum alloy castor tooth class part positioning fixture that obturages, includes:
the clamp comprises a clamp body 1, a gland 2 and a quick-release ring 3;
the clamp body 1 is fixed on a chuck of a numerically controlled lathe, and a threaded hole is formed in the center of the clamp body 1; the center of the quick-release ring 3 is provided with a boss, the periphery of the boss is externally provided with external threads and is screwed in the threaded hole of the clamp body 1 from the right side, and the center of the boss is a quick-release hole; the part 4 is inserted into the clamp body 1 from the right side and is positioned on the right side of the quick release ring 3; the gland 2 is screwed on the clamp body 1, and the part 4 is limited on the clamp body 1.
The gland 2 adopts a thin-wall annular spiral gland.
The inside diameter of the clamp body 1 is in small clearance fit with the outside diameter of the part, and the clearance is not more than 0.01 mm.
The quick-release hole is a hexagonal hole or a square hole.
When the quick-release hole is a hexagonal hole, the quick-release ring 3 is rotated from the right end face of the clamp body 1 through a hexagonal wrench, and the quick-release ring 3 is screwed out along the axial direction, so that the whole part is ejected out.
The part 4 is made of aluminum alloy.
The utility model has the advantages that: the positioning fixture adopts a thin-wall annular spiral gland, so that the thickness of the gland is reduced, the shortest suspension length of a cutter is ensured, the compression area is increased, and parts are prevented from being locally crushed; the positioning fixture is in small clearance fit with the part. Before machining, the end face and the outer diameter reference of the positioning clamp are aligned, the runout is not larger than 0.01mm, parts can be directly placed into the clamp during machining, and each part does not need to be independently aligned; after processing, the hexagonal wrench is used for rotating the quick pulling and disassembling device from the right end face of the clamp, and the pulling and disassembling device is screwed out along the axial direction, so that the part is integrally ejected out, and the damage to the surface of the part caused by the mode of applying destructive force such as smashing and prying is avoided.

Detailed Description
The present invention will be further explained with reference to the attached drawings in the embodiments of the present invention.
As shown in fig. 1, an aluminum alloy sealing grate tooth part positioning fixture comprises:
the clamp comprises a clamp body 1, a gland 2 and a quick-release ring 3;
the clamp body 1 is fixed on a chuck of a numerically controlled lathe, and a threaded hole is formed in the center of the clamp body 1; the center of the quick-release ring 3 is provided with a boss, the periphery of the boss is externally provided with external threads and is screwed in the threaded hole of the clamp body 1 from the right side, and the center of the boss is a quick-release hole; the part 4 is inserted into the clamp body 1 from the right side and is positioned on the right side of the quick release ring 3; the gland 2 is screwed on the clamp body 1, and the part 4 is limited on the clamp body 1. And a hexagonal wrench is used for rotating the hexagonal hole in the center of the quick release ring 3 from the right end face of the clamp body 1, so that the quick release ring 3 can move along the Z-axis direction of the numerical control lathe.
The positioning clamp gland adopts a thin-wall annular spiral gland, so that the thickness of the gland is reduced, the shortest suspension length of a cutter is ensured, the rigidity of the cutter is ensured, the compression area is increased, and parts are prevented from being locally crushed.
The internal diameter of the positioning clamp main body and the external diameter of the part are in small clearance fit, the end face and the external diameter reference of the positioning clamp are aligned before machining, the run-out is guaranteed to be not larger than 0.01mm, the part can be directly placed into the clamp during machining, and the part does not need to be aligned independently.
The gland is a thin-wall annular spiral gland. When compressing tightly, the gland keeps parallel with the part right-hand member face, forms the mode of face contact, has avoided the condition that the part was crushed.
The part is made of aluminum alloy, and the part is not easy to take out due to the influence of temperature after being processed. When the part is taken out, the surface of the part is pressed and scratched, so that the quick-release ring is arranged in the clamp.
The positioning clamp is internally provided with a device for rapidly pulling and unloading parts. The device is quickly pulled out from the right end face of the clamp through the rotation of the hexagonal wrench, and the device is screwed out along the axial direction, so that the part is integrally ejected out, and the damage to the surface of the part caused by the mode of applying destructive force such as smashing, prying and the like is avoided.
Examples
The embodiment is a positioning fixture for aluminum alloy sealed castor-tooth parts, and as shown in fig. 1, a fixture body 1 is fixed on a chuck of a numerically controlled lathe. The gland 2 is connected with the clamp body 1 and is connected with the clamp body 1 through a threaded structure. The quick-release ring 3 is connected with the clamp body 1 and is connected with the clamp body 1 through a threaded structure. The hexagonal wrench is used for rotating the hexagonal hole in the center of the quick release ring 3 from the right end face of the clamp body 1, so that the quick release ring 3 can move along the Z-axis direction of the numerical control lathe.
The utility model discloses a device is when using, at first fixes anchor clamps main part 1 on numerical control car flower disc, and 1 left end face of alignment anchor clamps main part and external diameter benchmark are put into anchor clamps main part 1 with the part, guarantee that the part terminal surface is hugged closely with 1 terminal surface of anchor clamps main part, screw gland 2 again on anchor clamps main part 1, guarantee under the prerequisite of cutter and clamp plate noninterference that the cutter hangs long minimum, carry out the tool setting operation. After processing, the removal ring 3 is rotated counterclockwise from the right end face of the clamp body 1 by using a hexagonal wrench, and the removal ring 3 is screwed out to eject the part.
In the embodiment, the quick positioning, deformation restraining and quick removal of the machined aluminum alloy sealed grate tooth parts are realized, the part clamping and aligning time is reduced, the qualified rate of the machined parts reaches 100%, and the surfaces of the parts are not crushed or scratched.
