Description

Technical Field

[0001] The present application relates to the technical field of turbocharger housing production, and in particular to a flaw detection device for turbocharger housing production. Background Art

[0002] A turbocharger is actually an air compressor that increases the intake volume by compressing air. It uses the inertial force of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber, and the turbine drives the coaxial impeller, which presses the air sent from the air filter pipe to enter the cylinder with pressure. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, and the impeller compresses more air into the cylinder. The increase in air pressure and density can burn more fuel. By increasing the amount of fuel and adjusting the engine speed accordingly, the engine output power can be increased.

[0003] like Figure 1 The turbocharger housing 5 shown has corresponding connecting holes on both sides of the housing. During the manufacturing process, in order to ensure the quality of the turbocharger housing, after the holes are opened, the parts around the holes need to be inspected. In the prior art, workers generally hold the probe of an ultrasonic flaw detector to inspect the inner wall of the housing. Due to the large number of inspections, the efficiency of manual inspection is low, and there is a situation where hidden flaws are overlooked, and the product quality cannot be fully ensured.

DETAILED DESCRIPTION

[0019] The following is combined with Figure 2-4 This application is described in further detail.

[0020] The present application embodiment discloses a flaw detection device for turbocharger housing production, referring to Figure 2-4 , comprising a workbench 1, on which an ultrasonic flaw detector 11 and a positioning platform 2 are installed, the positioning platform 2 has a support 21 adapted to the turbocharger housing, a clamping cylinder 22 for clamping the turbocharger housing is fixed to one side of the positioning platform 2, a clamping block is fixed to the piston rod of the clamping cylinder 22, a probe mechanism is arranged next to the positioning platform 2, the probe mechanism comprises a linear guide slide 31 vertically fixed on the workbench 1, a mounting frame 32 is fixed on the slide of the linear guide slide 31, a rotating shaft 33 is rotatably connected to the mounting frame 32, and a driving motor 34 for driving the rotating shaft 33 to rotate is also installed on the mounting frame 32;

[0021] An upper flaw detection mechanism 331 and a lower flaw detection mechanism 332 are installed on the rotating shaft 33. The upper flaw detection mechanism 331 and the lower flaw detection mechanism 332 both include a load-bearing rod 41 fixed on the side wall of the rotating shaft 33. An electric push rod 42 is fixed on the load-bearing rod 41. A movable block 43 is movably connected to the end of the load-bearing rod 41. The electric push rod 42 is used to push the movable block 43 to move. A probe 44 is installed on the side of the movable block 43 away from the electric push rod 42.

[0022] Reference Figure 4 A first spring 45 is connected between the movable block 43 and the probe 44 , a first telescopic sleeve is arranged inside the first spring 45 , and two ends of the first telescopic sleeve are respectively fixed to the movable block 43 and the probe 44 .

[0023] Reference Figure 4 A glue groove 46 is provided next to the probe 44, and a glue coating roller 47 is installed in the glue groove 46. The side of the movable block 43 away from the electric push rod 42 is an arc surface. A second telescopic sleeve is connected between the glue groove 46 and the movable block 43, and a second spring 48 is sleeved on the surface of the second telescopic sleeve.

[0024] By providing a glue groove 46 next to the probe 44, before each inspection, the staff only needs to squeeze an appropriate amount of lubricating liquid into the glue groove 46. When the glue coating roller 47 rotates along the inner wall of the turbocharger housing, the lubricating liquid can be applied to the inner ring wall of the turbocharger housing, which facilitates the sliding of the probe 44.

[0025] The arrangement of the first spring 45 and the second spring 48 can enable the probe 44 and the glue coating roller 47 to press against the inner wall of the turbocharger housing, ensuring that the coating and detection actions can be better completed.

The linear guide slide 31 drives the upper flaw detection mechanism 331 and the lower flaw detection mechanism 332 to move downward to the corresponding position of the turbocharger housing. Thereafter, the electric push rods 42 in the upper flaw detection mechanism 331 and the lower flaw detection mechanism 332 respectively work to push the rubber coating roller 47 and the probe 44 against the inner ring wall of the turbocharger housing. The driving motor 34 drives the rotating shaft 33 to rotate, and the rotating shaft 33 drives the probe 44 to perform flaw detection around the inner ring wall of the turbocharger housing, and the detection effect is good.

[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, principle and application direction of the present application should be included in the protection scope of the present application.
