[0026] A mounting base 5 is fixedly connected to the mounting frame 2, and a first reciprocating screw 16 and a second reciprocating screw 15 are horizontally mounted in the mounting base 5. An organic body 34 is mounted on the side wall of the mounting base 5, and one end of the first reciprocating screw 16 and the second reciprocating screw 15 both extend into the organic body 34 and are connected through a gear transmission assembly. A second motor 4 is mounted on the side wall of the organic body 34, and an output end of the second motor 4 is connected to the first reciprocating screw 16 through a first one-way bearing. The gear transmission assembly includes a first gear 17 and a second gear 14, and the first gear 17 is mounted on the first reciprocating screw 16, and the second gear 14 is mounted on the second reciprocating screw 15, and the first gear 17 and the second gear 14 are meshed, and the second gear 14 and the second reciprocating screw 15 are connected through a second one-way bearing; A loading mechanism is installed on the first reciprocating screw 16, and a camshaft is installed between the loading mechanism and the connecting clamping mechanism.

The detector 8 can accurately detect various parameters of the camshaft and provide reliable data support for the quality evaluation of the camshaft.

[0028] First, install the camshaft and insert one end of the camshaft into the circular hole and the through hole. Then, the threaded rod 26 can be rotated by rotating the knob 24, thereby driving the movable seat 28 to move. During the movement of the movable seat 28, the push block 23 drives the movable frame 31 to rotate. The movable frame 31 cooperates with the rotating frame 30 to move the clamping seat 25, thereby clamping one end of the camshaft to fix one end of the camshaft. Then turn on the second motor 4, the second motor 4 rotates forward, and the second motor 4 drives the first reciprocating screw 16 to rotate, driving the T-shaped frame 18 to move in the direction of the camshaft until the loading seat 6 fixes the other end of the camshaft, thereby realizing the installation of the camshaft.

[0029] When the camshaft is being inspected, when the second motor 4 rotates forward, the first one-way bearing works, driving the first reciprocating screw 16 to rotate, and the first gear 17 on the first reciprocating screw 16 drives the second gear 14 to rotate through gear meshing, but due to the setting of the second one-way bearing, the second reciprocating screw 15 does not rotate. Conversely, when the second motor 4 rotates reversely, the first one-way bearing and the first gear 17 rotate accordingly, but due to the setting of the first one-way bearing, the first reciprocating screw 16 does not rotate accordingly, and the first gear 17 drives the second reciprocating screw 15 to rotate through gear meshing, so that the second motor 4 can rotate forward to rotate the first reciprocating screw 16 to drive the loading mechanism to move, and the second motor 4 rotates reversely to drive the second reciprocating screw 15 to rotate, thereby driving the detection mechanism to move.

The T-shaped frame 18 is cooperatively connected to the first reciprocating screw 16. When the second motor 4 drives the first reciprocating screw 16 in the forward direction, the T-shaped frame 18 can move on the first reciprocating screw 16. The T-shaped frame 18 is fixedly connected to the loading seat 6, which can apply a certain load to the camshaft.

[0031] The detection mechanism includes a movable plate 20, the two ends of which are slidably connected to the corresponding limiting slots 12. The two ends of the movable plate 20 are fixedly connected to a second slider 22, and each second slider 22 is slidably connected to the corresponding limiting slot 12 to ensure the stable sliding of the movable plate 20.

When the second motor 4 rotates in the opposite direction, the second reciprocating screw 15 rotates, and the moving seat 21 drives the movable plate 20 to move. A U-shaped frame 7 is installed on the movable plate 20, and two detectors 8 are symmetrically installed on the U-shaped frame 7. The detectors 8 can detect the camshaft.

[0032] The first motor 11 is started, driving the connecting clamp mechanism through the reducer 9 to rotate, causing the camshaft to rotate. Simultaneously, the second motor 4 is started and rotated forward or reverse as needed, driving the first and second reciprocating screws 16 and 15 to rotate via the one-way bearing and gear transmission assembly. The first reciprocating screw 16 drives the loading mechanism to move and apply a load to the camshaft, while the second reciprocating screw 15 drives the detection mechanism to move, and the detector 8 performs a test on the camshaft, achieving a comprehensive test of the camshaft of the new energy vehicle.
