Referring to fig. 1, a load-bearing platform 100 includes a first support structure 110 and a fixed structure 120. The first support structure 110 is used for supporting the workpiece 500 to be detected and enabling the workpiece 500 to rotate around a reference axis of the first support structure; and a fixing structure 120 for fixing the workpiece 500 on the first support structure 110.

In practical use, after the workpiece 500 is placed on the first support structure 110, the fixing structure 120 may fix the workpiece 500, so that the inspection assembly 300 in the inspection apparatus performs a static inspection on the workpiece 500; when the static inspection of the workpiece 500 is completed, the fixing structure 120 is separated from the workpiece 500, and the first supporting structure 110 drives the workpiece 500 to rotate around its own reference axis, so that the inspection assembly 300 in the inspection apparatus completes the dynamic inspection of the workpiece 500.

In some embodiments, only one first support wheel 111 may have a first rotary drive 112 connected thereto. In practical use, the first rotary driving member 112 drives one of the first supporting wheels 111 to rotate, the first supporting wheel 111 drives the supported workpiece 500 to rotate, and the workpiece 500 drives the other first supporting wheel 111 to rotate, so that the workpiece 500 rotates around its own reference axis on the first accommodating portion 113.

For example, when the first fixing driving member 121 is a jaw cylinder, the fixing members 122 may be jaws respectively disposed on driving ends of the jaw cylinder. When the workpiece 500 is to be fixed on the first support structure 110, the first fixing driving member 121 can drive the fixing members 122 to clamp the workpiece 500 to each other.

Of course, in some embodiments, if the workpiece 500 itself includes a hole or a groove, after the workpiece 500 is placed in the first accommodating portion 113, the fixing member 122 can be inserted into and clamped in the hole or the groove of the workpiece 500 by the first fixing driving member 121, so as to fix the workpiece 500. In this case, the first fixing driving member 121 may be a lifting cylinder, and the fixing member 122 may be a latch, and the size of the latch is generally adapted to the size of the hole or the groove.

For example, in actual use, the first fixing driving member 121 drives the fixing member 122 to lift up to a position where a hole in the workpiece 500 can be inserted, and then the workpiece 500 is loaded onto the first accommodating portion 113, and the hole in the workpiece 500 is inserted into the fixing member 122, so that loading and fixing of the workpiece 500 are completed, and generally, the position of the hole of each workpiece 500 is fixed, and the position of the fixing member 122 is also fixed, so that positioning of the workpiece 500 can be realized when the hole is inserted into the fixing member 122, and at this time, static detection of the workpiece 500 can be performed; after the static detection of the workpiece 500 is completed, the first fixing driving element 121 can drive the fixing element 122 to move towards the direction of the release hole, so that the fixing element 122 is released from the release hole, and at this time, the first supporting wheel 111 can drive the workpiece 500 to rotate around its own reference axis, thereby realizing the dynamic detection of the workpiece 500.

As can be seen, in the load-bearing platform 100 of the present application, the first rotary driving element 112 is in driving connection with one or two first supporting wheels 111 arranged oppositely, so that the workpiece 500 loaded on the first accommodating portion 113 matched between the two first supporting wheels 111 can rotate around its reference axis, and further the workpiece 500 can be dynamically detected; in addition, a first fixed driving element 121 and a fixing element 122 are further provided, and the first fixed driving element 121 can drive the fixing element 122 to clamp the workpiece 500, thereby facilitating the static detection of the workpiece 500.

Specifically, the first fixed driving member 121 is used for driving the fixing member 122 to move in the vertical direction, so that the fixing member 122 can be inserted into or separated from the hole or groove of the workpiece 500; the second fixing driving member 123 is used for driving the fixing member 122 to perform an opening and closing movement, so that the fixing member 122 can abut against or release the hole wall or the groove wall. At this time, the first fixing driving member 121 may be a lifting cylinder, the second fixing driving member 123 may be an opening and closing cylinder, and the fixing members 122 may be bolts respectively disposed on driving ends of the opening and closing cylinders.

When the device is actually used, the first fixing driving element 121 drives the fixing element 122 to rise to a position where the hole in the workpiece 500 can be inserted, then the workpiece 500 is loaded onto the first accommodating portion 113, the hole in the workpiece 500 is inserted into the fixing element 122, then the second fixing driving element 123 drives the fixing element 122 to open, the fixing element 122 abuts against the hole wall, and the workpiece 500 is fixed by the fixing element 122, so that the static detection of the workpiece 500 can be realized; after the static detection of the workpiece 500 is completed, the second fixed driving member 123 drives the fixing member 122 to merge, and then the first fixed driving member 121 drives the fixing member 122 to move toward the direction of the releasing hole, so that the fixing member 122 is released from the hole, and at this time, the first supporting wheel 111 can drive the workpiece 500 to rotate around its own reference axis, thereby realizing the dynamic detection of the workpiece 500.

That is to say, the second fixing driving element 123 is arranged to drive the fixing element 122 to perform the opening and closing movement, so that the workpiece 500 can be better fixed, and meanwhile, the carrying platform 100 can be compatible with workpieces 500 with different aperture sizes.
