After the upper connecting seat two 410 and the lower connecting seat two 411 are connected by fasteners, the connecting rod 412 can be fixed, and when the telescopic rod 49 is extended, the upper connecting seat two 410 is lowered, and then the lower connecting seat two 411 and the fixed connecting rod 412 are lowered synchronously. Conversely, when the telescopic rod 49 is retracted, the lower connecting seat two 411 and the fixed connecting rod 412 are raised synchronously, so that the height of the upper connecting seat two 410, the lower connecting seat two 411 and the fixed connecting rod 412 is adjusted.

[0032] It should be noted that the axis of the semicircular through groove one and the axis of the semicircular through groove two are in the same vertical plane, and then when the upper connecting seat one 47 is removed from above the lower connecting seat one 46 and the lower connecting seat two 411 is removed from below the upper connecting seat two 410, the connecting rod 412 can be fixed by moving the horizontal position of the connecting rod 412, and when the axis of the semicircular through groove one and the axis of the semicircular through groove two are collinear, the fixing of the connecting rod 412 by the lower connecting seat one 46 and the upper connecting seat one 47 is exchanged with the fixing of the connecting rod 412 by the upper connecting seat two 410 and the lower connecting seat two 411. At this time, the handle of the angle adjuster 5 is fixed by the connecting part, and the connecting part is sleeved on the connecting rod 412, so that the position change does not occur due to the change of the horizontal position of the connecting rod 412.

The detection module further comprises an identification unit arranged therein and used for identifying the size of the deformed picture of the positioning hole of the angle adjuster 5 after the angle adjuster 5 is disassembled after the handle of the angle adjuster 5 is driven to move for a certain number of times. Thus, the deformation of the positioning hole of the angle adjuster 5 can be judged, so as to obtain the strength of the angle adjuster 5.

[0035] The working method of the strength detection equipment of the automobile seat angle adjuster comprises the following steps. Step one: install and fix the angle adjuster 5, and fix the angle adjuster 5 in a detection state.

[0036] Specifically, when environmental simulation is needed, the box bottom 21 is fixed on the top of the movable platform 11 by using fasteners, and then the base 31 is fixed on the top of the inside of the box bottom 21 by using fasteners. After the box cover 22 is closed, the airflow carrying the environmental simulation source is introduced, and the environmental simulation can be performed. When environmental simulation is not needed, the box bottom 21 and the base 31 can be fixed in the manner of environmental simulation, and the box bottom 21 can be closed or opened according to actual needs. Alternatively, the base 31 can be directly fixed on the top of the movable platform 11 by using fasteners.

[0037] The angle adjuster 5 is placed between the fixed plate one 34 and the limiting plate 35, the side of the angle adjuster 5 provided with the positioning hole is close to the fixed plate one 34, according to the detection needs, the positioning rod 37 is penetrated through the limiting hole on the fixed plate one 34 and the mounting hole on the angle adjuster 5, the number and position of the mounting hole actually fixed and limited are adjusted, then the limiting ring 38 is used to fix the positioning rod 37 on the fixed plate one 34, then the staff uses two groups of tools to fix the two groups of rotating heads 36 respectively, and drives the rotating heads 36 to rotate forward or reverse, thereby driving the bidirectional screw rod 32 to rotate, so that the two groups of sliding blocks 33 are close to each other, the angle adjuster 5 between the fixed plate one 34 and the limiting plate 35 is clamped, and the position fixing of the angle adjuster 5 is completed.

[0038] When it is needed to slowly drive the handle of the angle adjuster 5 to move, the connecting rod 412 is fixed by using the lower connecting seat one 46 and the upper connecting seat one 47, the motor 44 is controlled to start rotating, the connecting rod 412 is driven to rise and fall slowly by the gear transmission mode, the lower connecting seat one 46 and the upper connecting seat one 47 are driven to rise and fall slowly, and the handle of the angle adjuster 5 is slowly adjusted; when it is needed to quickly drive the handle of the angle adjuster 5 to move, the connecting rod 412 is fixed by using the upper connecting seat two 410 and the lower connecting seat two 411, the upper connecting seat two 410 and the lower connecting seat two 411 are driven to rise and fall quickly by the telescopic rod 49, and the handle of the angle adjuster 5 is quickly adjusted. The handle of the angle adjuster 5 is adjusted to the bottom end, the handle is fixed by using the hoop 416, the number and thickness of the gasket 417 are adjusted, the stop block 418 and the gasket 417 are fixed on the side of the movable sleeve 415 by using the fastener, so that the stop block 418 contacts the end of the handle, at this time, the connecting rod 412 is in a lower position corresponding to the lowest position of the handle of the angle adjuster 5, according to whether the environmental simulation source is needed and the closing state of the box cover 22, the positioning block 414 is fixed on the box bottom 21, then the handle on the box cover 22 is pulled, so that the box cover 22 is in the closed state with the box bottom 21, and the handle on the box bottom 21 is buckled by using the lock 25.

[0039] Step two: drive the handle of the angle adjuster 5 to move, and detect the strength and obtain the strength detection result.

[0040] Specifically, the six-degree-of-freedom platform 1 is controlled to start, the angle adjuster 5 fixed thereon is driven to realize translation and rotation movement in any direction in the three-dimensional space, the motor 44 is controlled to start, the connecting rod 412 is driven to rise and fall slowly, the connecting part is driven to rise and fall slowly, or the telescopic rod 49 is controlled to start, the connecting rod 412 is driven to rise and fall quickly, the connecting part is driven to rise and fall quickly, the handle of the angle adjuster 5 is moved, after a set number of movements, the angle adjuster 5 is taken off from the fixing mechanism 3, and the deformation of the mounting hole on the angle adjuster 5 is obtained by the detection module.

[0041] The detection module is provided with a standard shape corresponding to each mounting hole of the standard angle adjuster 5. When the shape of the mounting hole after strength detection deviates from the standard shape, that is, when the mounting hole is deformed, the strength of the corresponding mounting hole is low. When the mounting hole after strength detection deviates from the standard shape by more than a certain proportion of the mounting holes being detected, the overall strength of the angle adjuster 5 is low.

[0042] Specifically, the detection module is provided with a standard shape corresponding to each mounting hole, the area of the standard shape is , the maximum length in the standard shape is , the minimum length is , the area of the shape of the mounting hole after detection is , the maximum length in the shape of the mounting hole after detection is , the minimum length is , i is the number sequence corresponding to the mounting hole of the angle adjuster 5, , n is the total number of mounting holes of the angle adjuster 5, the detection module is also provided with a threshold value N for judging the deformation degree of the mounting hole and a number threshold value M for judging the overall strength of the angle adjuster 5. The deformation degree of the mounting hole is the product of the absolute value of the difference between the maximum length before and after detection and the absolute value of the difference between the minimum length before and after detection. When the product is greater than the threshold value of the deformation degree, the deformation of the mounting hole is large. At the same time, the detection module counts the deformation. When the count value reaches the number threshold value, it can be determined that the main reason for the abnormal strength of the angle adjuster 5.

[0043] It should be noted that for circular mounting holes , for slot-shaped holes, .
