DETAILED DESCRIPTION

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 and Figure 4 As shown in this embodiment, an auxiliary testing device for testing optical lenses includes a mounting frame 1 and a stabilizing sleeve 3. The mounting frame 1 is located at the top of the stabilizing sleeve 3. Two positioning components 4 are installed inside the mounting frame 1, and the two positioning components 4 are arranged in a circumferential array. The positioning components 4 include three limiting grooves 401 opened inside the mounting frame 1. Each of the three limiting grooves 401 is slidably connected to a movable seat 402. Each of the three movable seats 402 is hinged to a driving rod 403 at the bottom. The bottom end of each of the three driving rods 403 is hinged to the same connecting frame 404. An electric telescopic rod 405 is fixedly installed on one side of the bottom outer wall of the mounting frame 1. The output end of the electric telescopic rod 405 is fixedly connected to the connecting frame 404.

[0025] Each of the three movable seats 402 has a lead screw 406 threadedly connected to its upper half. Each of the three lead screws 406 has a positioning plate 408 rotatably connected to its close side. Each of the three positioning plates 408 has two limiting rods 407 fixedly connected to its far side. The six limiting rods 407 are slidably inserted into the three movable seats 402.

[0026] Place the camera to be tested on top of the mounting bracket 1, ensuring it aligns with the side positioning plate 408. Then, activate the electric telescopic rod 405 at the bottom of the mounting bracket 1. The connecting bracket 404 is driven downward by the output end of the electric telescopic rod 405. The top of the drive rod 403 is restricted from moving downward, while the bottom is driven downward by the connecting bracket 404. The drive rod 403 and the moving seat 402 will be driven to move closer to the camera along the limiting groove 401. The camera is first pushed by the side positioning plate 408, and simultaneously, the camera is also pushed towards the middle position of the mounting bracket 1 by the positioning plates 408 at both ends. Then, the position of the camera will be firmly fixed. If the camera model changes, the knob drives the lead screw 406 to rotate. The positioning plate 408, which is restricted by the limiting rod 407, can only move horizontally. The lead screw 406 can then drive the positioning plate 408 to move horizontally, allowing different camera models to be fixed by the positioning component 4 at once, which helps improve the adaptability of the device.

[0029] After the detection is completed, the hydraulic cylinder 503 in the stabilizing sleeve 3 is started, the output end of the rack 504 is driven to move by the hydraulic cylinder 503, the rack 504 drives the gear 502 to rotate half a circle through engagement, the connecting rod 501 rotates synchronously with the gear 502, and the other positioning assembly 4 replaces the position of the positioning assembly 4 in use, so that the camera completing detection can be removed in the new camera detection process, and the working efficiency of the device is improved.

[0030] As shown in Figure 3 , the stabilizing sleeve 3 is fixedly connected with two abutting blocks 505 corresponding to the position of the rack 504 at the inner wall of the bottom, one of the abutting blocks 505 is attached to the rack 504, when the mounting frame 1 is adjusted, the rack 504 will be in contact with the abutting block 505, and the adjustment accuracy is improved.

[0031] As shown in Figure 1 and Figure 3 , the connecting ring 2 is rotatably connected to the inner wall of the stabilizing sleeve 3, and the mounting frame 1 is fixedly connected to the outer wall of the top of the connecting ring 2, so that the rotation of the mounting frame 1 is not affected, and the stability of the mounting frame 1 is improved.

[0032] As shown in Figure 4 , the thread angle of the external thread of the lead screw 406 is smaller than the equivalent friction angle, so that when the positioning plate 408 connected with the lead screw 406 is subjected to an external force, the lead screw 406 will not move along the moving seat 402.

[0033] The utility model provides a kind of auxiliary detection device for optical lens test, specific working principle is as follows:
