Description

Technical Field

[0001] This utility model relates to the technical field of fixtures for machining turbocharger housings, specifically a fixture for machining turbocharger housings. Background Technology

[0002] A turbocharger increases the intake air volume by compressing air. It uses the inertial force of the exhaust gas from the engine to drive a turbine in the turbine housing. The turbine then drives a coaxial impeller, which compresses the air supplied by the air filter and forces it into the cylinder. As the engine speed increases, the exhaust gas velocity and turbine speed also increase simultaneously, causing the impeller to compress more air into the cylinder. The increased air pressure and density allow for the combustion of more fuel. By increasing the amount of fuel and adjusting the engine speed, the engine's output power can be increased. In turbocharger manufacturing, fixtures are used to clamp and fix the turbocharger housing.

[0003] Utility model patent CN207788728U discloses a tooling fixture for a turbocharger, including a support platform. Support legs are fixedly connected to the bottom of the support platform, and a first support column and a second support column are fixedly connected to the top of the support platform. A first sleeve is fixedly connected to the top of the right side surface of the first support column. A first threaded rod is sleeved on the end of the first sleeve away from the first support column. A first connecting plate and a second connecting plate are sleeved on the surface of the first threaded rod. A first bearing is fixedly sleeved on the top of the surface of the second support column. This tooling fixture for the turbocharger includes a first support column, a second support column, a first sleeve, a first threaded rod, a first connecting plate, a second connecting plate, a first bearing, and a first handle. Rotation of the first handle drives rotation of the first threaded rod, which in turn drives the first connecting plate to move left and right.

[0004] However, this utility model cannot adapt to the irregular appearance of the turbocharger housing for clamping during use, resulting in poor performance. Utility Model Content

[0013] Beneficial effects:

[0014] This utility model provides a fixture for machining turbocharger housings, which has the following advantages:

[0015] The movement of two sliders towards each other can drive the movement of two pairs of chucks towards each other. The relative movement of one pair of chucks can accommodate the irregular shape of the turbocharger housing for clamping. The rotation of the boss can drive the housing to rotate, so that the other side of the housing can face the worker. Attached Figure Description
