Description

Technical Field

[0001] The utility model relates to the technical field of detection tooling, in particular to a gasket detection device. Background Art

[0002] The motor housing is an important component of the motor of new energy vehicles, and its performance has an important impact on the endurance and service life of new energy vehicles. At present, the motor housing of new energy vehicles is usually assembled from two or more components. During the use of the motor housing, the entry of rainwater and moisture may cause leakage of the motor, thereby reducing the performance of the motor. Therefore, it is necessary to add gaskets to the contact surfaces of the components when assembling the motor housing to improve the sealing.

[0003] The existing gasket detection device can detect the missing or over-installation of the motor housing gasket, thereby avoiding the risk of motor housing leakage. However, corresponding detection devices are required for parts of different sizes, which has poor applicability. In addition, during the detection process, the detection can only be carried out after the assembly is completed. If the detection fails, rework and reassembly are required, which is inefficient.

[0013] The mounting base plate is provided with bolt holes, which are used to cooperate with bolts to mount the gasket detection device on the fixture.

[0014] The beneficial effects of the utility model are as follows:

[0015] The utility model can detect the missing of the gasket of the motor housing and prevent over-installation. The gasket assembly can be tested during the assembly process, and the next process can be carried out after the test is qualified.

[0024] The structure of the lifting support assembly includes a mounting base plate 6 on which a support column 8 is arranged. The support column 8 is provided with a cylinder mounting plate 1 that can slide along the support column. The cylinder 10 is mounted on the cylinder mounting plate 1.

[0025] Specifically, a mounting hole is provided on the cylinder mounting plate 1. When the cylinder mounting plate 1 is raised or lowered along the guide column 3 to a desired height, the mounting hole is used to cooperate with a locking member to lock the cylinder mounting plate 1 and the guide column 3.

[0026] Specifically, a support bracket fixing seat 9 is provided on the installation base plate 6 , and the bottom end of the support bracket 8 is fixed in the support bracket fixing seat 9 .

[0027] Specifically, the mounting base plate 6 is provided with bolt holes, which are used to cooperate with bolts to mount the gasket detection device on the fixture.

[0029] See also Figures 1 to 3 In this embodiment, the motor housing to be tested is assembled by part 15 and part 2 16. During the assembly process, one or more gaskets need to be set on the assembly surfaces 17 of the two parts. The specific workflow includes:

[0030] (1) Connect one end of the proximity switch 11 to the PLC terminal of the assembly equipment so that it can receive the induction signal;

[0031] (2) During the assembly process, first place the part 15, the edge of its assembly surface 17 has a detection surface 14, and the height of the cylinder mounting plate 1 is adjusted according to the position of the detection surface 14;

[0032] (3) Start the cylinder 10 so that the detection block 5 can move onto the detection surface 14 without interfering with the parts, and keep the gap with the detection surface 14 no greater than the thickness of the gasket to be installed;

[0033] (4) Install the gasket on the assembly surface 17. During the assembly process, the gasket will push the detection block 5, thereby moving the guide column 3, and then the sensing gasket 4 installed at the end of the guide column 3 can contact the proximity switch 11. The PLC receives the signal and determines whether the gasket has been installed. If qualified, it will proceed to the next step. If not, it will not be able to proceed to the next step.
