[0002] The C-benchmark detection device for the chassis trailing arm of new energy vehicles is a device specially used to detect and evaluate the chassis trailing arm components of new energy vehicles. The chassis trailing arm of new energy vehicles refers to an important component installed on the chassis of new energy vehicles, which is used to connect the body and wheels, support the body structure and transmit suspension force and driving force. It is usually made of high-strength and high-rigidity materials to ensure its stability and durability when bearing vehicle loads and driving.

[0003] However, most traditional new energy vehicle chassis trailing arm C reference detection devices cannot rotate in various directions after clamping and positioning the new energy vehicle trailing arm components, which makes it impossible for the detection device to comprehensively scan and detect various parameters of the new energy vehicle trailing arm components, which may affect the accuracy and precision of the detection results.

The meshing control rotates the rotating table 6, and slide grooves 8 are provided on both sides of the upper surface of the rotating table 6. A moving seat 11 slides inside the slide groove 8, and a support rod 13 is fixedly connected to the center of the upper surface of the moving seat 11, and a second servo motor 14 is fixedly connected to the center of the upper surface of the support rod 13, and a third gear 15 is fixedly connected to the output end of the second servo motor 14.

A placement block 18 is fixedly connected to the front end and the rear end of the outer wall of the rotating rod 16 away from the support rod 13. A limiting groove 19 is provided at the center of the outer wall of the placement block 18 away from the rotating rod 16, and a spring 20 is provided on one side of the inner wall of the limiting groove 19.

[0036] Compared with most traditional new energy vehicle chassis trailing arm C-reference detection devices, the first servo motor 4 provided in the new energy vehicle chassis trailing arm C-reference detection device controls the longitudinal rotation of the rotating table 6 through the engagement of the first gear 5 and the second gear 7, and the second servo motor 14 controls the lateral rotation of the rotating rod 16 through the engagement of the third gear 15 and the fourth gear 17, so that the new energy vehicle chassis trailing arm clamped on the push plate 23 can be detected in all directions. The multi-directional detection can cover various key parameters of the trailing arm components, ensuring a more comprehensive detection of the overall parameter structure of the new energy vehicle chassis trailing arm, thereby improving the detection effect of the detection device.

[0037] The front and rear ends of the inner walls on both sides of the slide groove 8 are fixedly connected with slide bars 9, and the outer walls of the front and rear ends of the moving seat 11 are fixedly connected with sliders 12.
