[0013] A detection method for a detection device of automotive parts includes the following steps:

[0014] S1. Position the top handle of the vehicle: Place the top handle of the vehicle on the first fixture and two second fixtures. The vertical reciprocating mechanism drives the positioning plate to slide downward vertically along multiple support rods. The two third positioning cylinders at the bottom of the positioning plate respectively move to be sleeved with the second clamping rods. The positioning plate drives the two second fixtures to move downward. The two second fixtures move to separate from the bottom of the top handle of the vehicle. The second guide rods at the bottom of each second fixture respectively slide downward vertically on the base. The second guide rods drive the sliding plate to slide downward vertically on the fixed rod. The sliding plate drives the third guide rod to slide downward vertically on the base. The third guide rod drives the first fixture to move downward vertically. The first fixture moves to separate from the bottom of the top handle of the vehicle.

[0016] S3. The detection mechanism detects the strength of the spring clamping grooves on the two side plates of the top handle of the vehicle and the bearing capacity of the spring clamping grooves on the side plates of the top handle of the vehicle.

[0017] Further, the method for the vertical reciprocating mechanism to drive the positioning plate to slide vertically along multiple support rods in S1 is as follows: The output shaft of the first motor drives the first gear to rotate. The first gear drives the second gear to rotate through meshing transmission with the second gear. The second gear drives the sleeve to rotate. The screw rod is threadedly connected with the internal thread on the inner circumference of the sleeve to drive the screw rod to move vertically. The screw rod drives the positioning plate to move vertically along multiple support rods;

[0018] The method for the detection mechanism in S3 to detect the strength of the spring clamping grooves on the two side plates of the car top handle is as follows: The output end of the first electric cylinder drives the ejector rod to move in the vertical direction.

The first camera takes pictures of the spring clamping groove of the car top handle to judge whether it is deformed, and detects the bearing capacity of the spring clamping groove on the side plate of the car top handle through the pressure sensor.

[0019] The beneficial effects of the present invention are as follows: (1) After positioning the car top handle, the loading arm detects the strength of the main handle of the car top handle, detects the bearing capacity of the main handle of the car top handle. At the same time, the detection mechanism detects the strength of the spring clamping grooves on the two side plates of the car top handle, and detects the bearing capacity of the spring clamping groove on the side plate of the car top handle, which can detect the strength of the main handle and the spring clamping grooves on the side plates of the car top handle at the same time, fully detect the car top handle, and ensure the accuracy of the detection result.

[0020] (2) The car top handle is placed on the first fixture and two second fixtures. The positioning plate drives the two second fixtures to move downward. The two second fixtures move to separate from the bottom of the car top handle. The third guide rod drives the first fixture to move downward in the vertical direction. The first fixture moves to separate from the bottom of the car top handle. The two first positioning cylinders, the two second positioning cylinders and the positioning plate position the car top handle, which is convenient for subsequent strength detection of the car top handle.

[0021] (3) One end of each pressure rod moves in the groove of the swing plate respectively. One end of each pressure rod abuts against the pressure sensor respectively. The loading rod at the other end of each pressure rod abuts against the spring clamping groove of the car top handle respectively. The bearing capacity of the spring clamping groove on the side plate of the car top handle is reflected through the pressure sensor. Description of the Drawings
