[0002] New energy vehicle PTC is a device used to heat the battery and the in-vehicle air conditioning system in a low temperature environment to ensure the normal operation of the vehicle. The aluminum shell of the new energy vehicle PTC is the outer shell of the heater, which is usually made of aluminum alloy because aluminum alloy has the advantages of light weight, good thermal conductivity and high mechanical strength.

[0003] At present, when testing multiple apertures and sizes of the same new energy vehicle PTC aluminum shell, multiple types of inspection fixtures are needed for testing. The inspection fixtures have a single function, that is, after the product completes the aperture or size detection of some positions on one inspection fixture, the staff needs to remove the product and install it on another inspection fixture to perform aperture and size detection at other positions. The product is repeatedly disassembled and replaced with inspection fixtures, which is not only cumbersome to operate, but also easy to cause detection errors if the installation is inaccurate, and qualified products are judged as inferior products, thereby reducing the product qualification rate.

[0004] Therefore, a composite inspection fixture for the production of PTC aluminum shells for new energy vehicles is proposed, which can detect the aperture and size of through holes in different directions and sizes of new energy vehicle PTC aluminum shell products, reduce detection errors, and thus improve product qualification rate. At the same time, it is convenient for product positioning and fixation, and can simultaneously measure the apertures in the horizontal and vertical directions, thereby improving the comprehensive detection capability of the inspection fixture.
