[0031] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0034] When the camera needs to be tested, it is placed on the inner side corresponding to the outer clamping plate 10 at the top of the turntable 4, so that the outer clamping plate 10 is close to the outer edge of the camera lens. At this time, the driving device 7 is started to rotate. Since its output end and the rotating sleeve 6 are in a threaded locking state, at this time, its output end drives the rotating sleeve 6 to rotate on the top of the turntable 4 to drive the propulsion component 8 to rotate and move. The displacement of the propulsion component 8 simultaneously pushes the clamping plate 9 to slide and move toward the direction of the outer clamping plate 10 until the clamping plate 9 is close to the inner edge of the camera, and the rotating sleeve 6 stops rotating and its inner wall The reverse thread is in a locked state with the center axis 5. At this time, the driving device 7 rotates in the reverse direction, and its output end is unlocked from the rotating sleeve 6. The steering mechanism 3 is started to drive the turntable 4 to rotate. At the same time, the center axis 5 drives the rotating sleeve 6 and the clamping plate 9 to rotate relative to the driving device 7, so that one group of clamped cameras is turned to the bottom of the test device. When the test is completed, the driving device 7 starts to operate again and locks the internal thread of the rotating sleeve 6. The bottom of the rotating sleeve is unlocked from the center axis 5, and the reverse rotation is continued to drive the clamping plate 9 to move in the reverse direction to release the clamping state of the camera.

[0035] The utility model can provide support for the camera to be tested by arranging the turntable 4 on the top of the steering mechanism 3, and at the same time, by arranging threads in opposite directions on the inner wall of the rotating sleeve 6 near the top and the bottom respectively, the rotating sleeve 6 can be driven to rotate forward and reversely in cooperation with the forward and reverse threaded connection between the driving device 7 and the inner wall of the central axis 5, and the propulsion component 8 makes the clamping plate 9 and the outer clamping plate 10 cooperate to provide a clamping effect for the camera during the test process, and when the test is completed, the reverse operation of the driving device 7 drives the rotating sleeve 6 to drive the clamping plate 9 to move in the reverse direction to quickly release the clamping effect on the camera, thereby making the operation more efficient and convenient during continuous testing operations, thereby improving the efficiency of the testing operations.

[0040] One end of the arc-shaped push plate 801 is rotatably connected to the outer side of the rotating sleeve 6. When the rotating sleeve 6 is driven to rotate in the forward direction, the arc-shaped push plate 801 is pushed to expand to push the rotating column 802 to generate thrust on the rotating block 803, thereby pushing the clamping plate 9 to slide and expand on the top of the turntable 4 to clamp on the inner edge of the camera, so as to achieve a quick clamping effect on the camera.

[0041] In one embodiment, for the above-mentioned steering mechanism 3, the steering mechanism 3 includes a steering motor 301, a steering bevel gear 302 is fixedly installed at the output end of the steering motor 301, a driving bevel gear 303 is meshed on one side of the steering bevel gear 302, a steering shaft 304 is fixedly installed on the top of the bevel gear 303, and the top of the steering shaft 304 is fixedly connected to the turntable 4.

[0045] The support frame 701 is fixed on the top of the test bench 1. When the driving motor 702 is started, the threaded shaft 703 is driven to rotate to drive the rotating sleeve 6 to rotate and push the arc-shaped push plate 801 to expand so that the clamping plate 9 can slide and move to expand. After the rotating sleeve 6 rotates for the first time, the bottom of its interior is locked with the inner wall of the central axis 5 by reverse threads. After the threaded shaft 703 rotates in the opposite direction, the locking state with the inner wall thread of the rotating sleeve 6 is released, thereby providing a rotational driving force for the rotating sleeve 6, and then providing an expansion and recovery driving force for the clamping plate 9, so that it can quickly lock and loosen the camera.

Until the turntable 4 continues to rotate, the extension plate 11 pushes the limit plate 1202 to squeeze the connecting spring 1203 to make it shrink toward the inside of the fixed plate 1201 to drive the limit plate 1202 to rotate and shrink, until the next group of outer clamping plates 10 rotate to this position, the connecting spring 1203 rebounds and drives the limit plate 1202 to reset and support it in the original position for positioning again.

[0048] In one embodiment, for the arc-shaped push plate 801 , there are a plurality of arc-shaped push plates 801 and a plurality of clamping plates 9 , and the plurality of clamping plates 9 are distributed on the top of the turntable 4 in a cross shape.

[0049] Through the cooperation of multiple sets of arc-shaped push plates 801 and the clamping plates 9, multiple positioning and clamping effects can be provided for camera testing on the top of the turntable 4, so as to facilitate continuous testing of the camera and improve production testing efficiency.

[0050] In one embodiment, for the above-mentioned test bench 1 , a support platform 13 is provided on the top of the test bench 1 , and the top of the support platform 13 fits with the bottom of the turntable 4 .

[0051] By adding the support platform 13 on the top of the test bench 1 , when the turntable 4 is rotating, the support platform 13 can play an auxiliary supporting role at the bottom thereof, so that the bottom of the turntable 4 has a stable supporting effect.

[0052] In one embodiment, for the above-mentioned support platform 13, the inner walls of the support platform 13 and the turntable 4 are both provided with rolling grooves, and the inner walls of the rolling grooves are provided with balls 14, and the number of the balls 14 is several.
