On the side wall, to ensure the stability of its position; further, a clamping clamp 3 is arranged on the outside of the support frame 2. When the workpiece is placed on the support frame 2, the corners of the workpiece are pressed down by means of the clamping clamp 3 to ensure the stability of its position and reduce the possibility of its deviation; further, a small aperture detection component 4 for detecting small apertures is arranged above the base 1 located on the outside of the support frame 2, and a large aperture detection component 5 is arranged above the base 1 opposite to the small aperture detection component 4. The small aperture detection component 4 is set to detect the periphery of the air inlet cavity. The small hole position is detected, and the large aperture detection component 5 is used to detect the aperture of the air inlet of the air inlet cavity to ensure the molding quality of the workpiece; further, a bracket detection component 6 is arranged on the upper rear side of the base 1, and the bracket detection component 6 includes a support rod 61, a connecting seat 62 is arranged above the support rod 61, and a removable hole position detection rod 63 is arranged in the connecting seat 62. A connecting plate 64 is arranged on the outer side of the plurality of hole position detection rods 63, and a handle 65 is arranged above the connecting plate 64. The specific description is as follows: the connecting seat 62 is designed in a T shape, and the plurality of hole position detection rods 63 are The concave shape arrangement corresponds to the setting position of multiple brackets to ensure the smooth progress of the detection work. Multiple hole detection rods 63 are movably connected to the connecting plate 64, which is convenient for people to synchronously adjust the positions of multiple hole detection rods 63 as a whole. Further, the end of the hole detection rod 63 can pass through the connecting seat 62 and correspond to the hole position on the bracket. If its end can smoothly enter the hole position of the bracket, the detection result is qualified. If the hole detection rod 63 is ejected, it is unqualified. This method is more intuitive and meets the use requirements.
[0021] In the above process: by setting a support seat arranged in a ring shape, the accuracy of the placement position of the workpiece to be inspected is ensured, and under the action of the clamping clamp 3, the workpiece can be tightened to prevent it from shifting, thereby ensuring the smooth progress of subsequent inspection work; by setting the bracket detection component 6, it can, to a certain extent, realize a more intuitive way of expressing whether the position of the workpiece bracket is accurate, providing convenient conditions for people to make markings, and at the same time, by utilizing the cooperation between the large-aperture detection component 5 and the small-aperture detection component 4, the detection of each hole position on the workpiece is effectively completed, the operation is simple and convenient, the use functionality is strong, and the work progress is effectively improved; the device is reasonably designed, simple in structure, easy to process, and can achieve the tightening of the workpiece position, reducing the possibility of its shifting.

The specific description is as follows: when people use the bracket detection component 6 to detect the accuracy of the bracket welding position, they manually hold the handle 65 and then drive each hole position detection rod 63 to move toward the position of the bracket. If the hole position is accurate, the hole position detection rod 63 can smoothly enter the hole of the bracket. When the hole is in the right position, if the hole position is inaccurate or offset, the bracket will hinder the hole position detection rod 63. At this time, the first spring piece 631 and the second spring piece 643 will be deformed under the action of force, and with the help of the established inclined groove 642, the first spring piece 631 will be separated from the positioning hole 641. In this way, the hole position detection rod 63 will be pushed out, and people can intuitively see which bracket is inaccurately positioned. The detection result is more obvious, which is convenient for people to mark it. Of course, the second spring piece 643 will also limit the first spring piece 631 to prevent it from shaking and affecting the detection process, effectively meeting the use requirements.
