Abstract
The utility model relates to a three-way joint turning clamp, which comprises a base, a core rod and a screw, wherein a through hole is formed on the base, the bottom of the core rod is tightly matched and connected with the through hole, and the clearance between the outer diameter of the part of the upper part of the core rod exposed out of the base and the inner diameter of a tee joint to be processed is 0.02 mm; the base is axially vertical to the through hole and is provided with two threaded holes along the diameter direction of the core rod, and the screw is in threaded connection with the base through the threaded holes. The utility model discloses can carry out quick, simple and convenient location clamping to three way connection, can not cause the part because of the deformation that the centre gripping leads to, improve machining efficiency.
Description
Technical Field
The utility model belongs to the technical field of aeroengine spare part makes, especially, relate to a three way connection car adds clamping apparatus.
Background
The three-way joint is responsible for two to three pipe connections as aeroengine oil through pipe way connecting piece, and the three-way joint processing degree of difficulty mainly lies in that the die forging coarse fodder size is uneven, the location is difficult, the centre gripping is yielding, consequently processing requires the precision strict, for guaranteeing product quality and precision, need carry out the clamping location to it with anchor clamps when processing the second end. At present, a three-jaw chuck is adopted for clamping and fixing in the turning process of the three-way joint, and when the first end is machined, the inner diameter is machined, and the three-jaw chuck is fixed, the force is not well controlled, so that the part is clamped and deformed.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model provides a three way connection car adds clamping anchor clamps carries out the clamping location to it when processing three way connection second end.
A three-way joint turning clamp comprises a base, a core rod and a screw, wherein a through hole is formed in the base, the bottom of the core rod is in tight fit connection with the through hole, and the unilateral clearance between the outer diameter of the part, exposed out of the base, of the upper part of the core rod and the inner diameter of a three-way joint to be machined is 0.02 mm; the base is axially vertical to the through hole and is provided with two threaded holes along the diameter direction of the core rod, and the screw is in threaded connection with the base through the threaded holes.
The utility model has the advantages that: the utility model discloses to three way connection's characteristics and design, this anchor clamps can carry out quick, simple and convenient location clamping to three way connection, can not cause the part because of the deformation that the centre gripping leads to, improve machining efficiency.

Detailed Description
For better explanation of the present invention, the following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings for better understanding.
As shown in fig. 1-2, a three-way joint turning clamp comprises a base 1, a core rod 2 and a screw 3, wherein a through hole is formed in the base 1, and the bottom of the core rod 2 is in close fit connection with the through hole; the unilateral clearance between the outer diameter of the part of the upper part of the core rod 2 exposed out of the base 1 and the inner diameter of the tee joint to be machined is 0.02mm, and the core rods 2 with different outer diameters are selected to clamp and position the tee joint 4 to be machined according to different sizes of parts to be machined; the base 1 is axially vertical to the through hole and is provided with two threaded holes along the diameter direction of the core rod 2, and the screw 3 is in threaded connection with the base 1 through the threaded holes.
In this embodiment, the inner diameter of the tee joint 4 to be processed is 6.32mm, and the outer diameter of the portion of the upper portion of the mandrel 2 exposed outside the base 1 is 6.28 mm. As shown in fig. 3, when in use, the lower part of the core rod 2 is fixed on the base 1 of the turning clamp, the base 1 is fixed on the turning equipment, then the part to be machined is inserted on the part of the core rod 2 exposed out of the base 1, and the two sides are locked by the screws 3, so that the clamping and positioning of the part are completed.
