DETAILED DESCRIPTION

[0018] The durability test device for the ignition lock of the automobile steering mechanism comprises a mounting bracket 1, an adjustment support frame 6, an assembly plate 7, a push cylinder 10, a limit block 8, an arc clamp 9 and a lock tongue 11 (see the attached manual). Figure 1 and 2 ).

[0019] A feeding slide plate 2 is mounted on the mounting bracket 1 through a feeding cylinder; a driving sleeve 5 is mounted on the feeding slide plate 2 through a driving motor 3 and a torque sensor 4. When the feeding slide plate 2 is working, the driving motor 3 and the driving sleeve 5 can be moved back and forth in cooperation with the feeding cylinder.

[0020] An adjustment support frame 6 is provided on one side of the mounting bracket 1 (see the attached manual). Figure 1 and 2 The adjustable support frame 6 includes two groups of legs 15, a fixed rod 16, a sliding rod 17 and a supporting cross plate 20; the two groups of legs 15 are symmetrically arranged; the legs 15 are symmetrically fixed with fixed rods 16; the inner side of the fixed rod 16 is slidably mounted with a sliding rod 17 through a sliding groove; the fixed rod 16 is provided with an assembly sliding hole 18; the fixed rod 16 is connected to the corresponding sliding rod 17 through the assembly sliding hole 18 and the locking screw 19. The top of the sliding rod 17 of the same leg 15 is provided with a supporting cross plate 20; the supporting cross plate 20 is provided with a transverse sliding hole 21 (see the attached manual) Figure 6 ).

[0021] The workpiece 22 can be assembled on the supporting cross plate 20 through bolts and the transverse sliding holes 21 . The purpose of setting the adjusting support frame 6 in this way is to adjust the position of the workpiece 22 by adjusting the position of the sliding rod 17 .

[0022] An assembly plate 7 is arranged above the adjustment support frame 6; a limit block 8 is fixedly mounted at the lower end of the assembly plate 7; a limit arc opening 12 is arranged at the bottom end of the limit block 8 (see the attached manual Figure 4 The bottom end of the limit block 8 is bolted with an arc clamp 9 (see the attached manual). Figure 4 The purpose of providing the arc clamp 9 is to enable the workpiece to remain relatively fixed with the limit block 8 under the cooperation of the arc clamp 9 during operation.

[0023] The assembly plate 7 above the limit block 8 is provided with an adjusting slide hole 13; the assembly plate 7 is provided with a push cylinder 10 (see the attached manual) through the adjusting slide hole 13 and the adjusting screw 14. Figure 4 and 5 The purpose of setting the adjusting slide hole 13 and the adjusting screw 14 is to adjust the installation position of the push cylinder 10 by adjusting the slide hole 13 and the adjusting screw 14 according to the different types of the workpiece to be detected during operation.

[0024] The push cylinder 10 is provided with a lock tongue 11, which extends to the lower end of the limit block 8 after passing through the limit block 8. When working, the push cylinder 10 can drive the lock tongue 11 to slide back and forth. When working, the push cylinder 10 can drive the lock tongue 11 to be inserted into the interior of the workpiece lock card.

[0025] When the endurance test device of the automobile steering mechanism ignition lock is working, the workpiece to be tested is first fixed on the adjustment support frame 6, and then the workpiece is fixed on the limit block 8 through the arc clamp 9. Then the feeding slide 2 drives the driving sleeve 5 to move toward the workpiece, and when the driving sleeve 5 is plugged and connected with the input end of the workpiece, the feeding slide 2 stops moving.

[0026] After the above work is completed, the driving motor 3 drives the input end of the workpiece to rotate to the left through the driving sleeve 5. During the rotation, the push cylinder 10 can drive the lock tongue 11 to insert into the inside of the workpiece lock card to lock the workpiece. At this time, the driving motor 3 continues to load. When the torque sensor 4 detects that the torque loading number is between 40Nm±2Nm, the push cylinder 10 drives the lock tongue 11 to reset; then the driving motor 3 drives the input end of the workpiece to rotate to the right through the driving sleeve 5. During the rotation, the push cylinder 10 can drive the lock tongue 11 to insert into the inside of the workpiece lock card to lock the workpiece. At this time, the driving motor 3 continues to load. When the torque sensor 4 detects that the torque loading number is between 40Nm±2Nm, the push cylinder 10 drives the lock tongue 11 to reset. At this point, the durability test device of the automobile steering mechanism ignition lock completes a detection action. Then the durability test device repeatedly cycles 2500 times. After the test is completed, the wear degree of the workpiece can be detected. At this point, the durability test device has completed the test. After each component is reset, a new workpiece is installed and the test device can enter the next working cycle.

[0027] The durability test device for the automobile steering mechanism ignition lock has a compact structure and ingenious design, and can simulate the stress condition of the lock tongue 11 inserted into the automobile steering mechanism ignition lock, thereby solving the problem that the existing ignition lock durability and performance testing equipment cannot meet the requirements of the steering mechanism ignition lock durability test, and is particularly suitable for the needs of the automobile steering mechanism ignition lock durability test.
