Description

Technical Field

[0001] The utility model relates to the technical field of lens fixing, in particular to a double-side locking lens fixing device. Background Art

[0002] In the automobile repair industry, the four-wheel aligner is a very important high-precision detection equipment. It uses a stable machine vision system and powerful software algorithms to complement each other to provide high-precision measurement results. Among them, the stability of the assembly method of the lens and camera in machine vision plays a very critical role in the calibration of camera parameters, and camera parameters are the most critical factor in measurement accuracy.

[0003] At present, the common lens assembly method in the four-wheel alignment industry is to use raw tape to screw or glass glue to tighten. This solution has the hidden danger of the lens loosening due to the aging of the raw tape, the aging of the glass glue and the temperature change. Once the lens is loose, the assembly accuracy of the lens and the camera will change, which will have a huge destructive effect on the subsequent measurement accuracy, resulting in inaccurate adjustment, excessive tire wear, excessive fuel consumption, poor handling and other problems.

[0004] Therefore, the utility model provides a double-side locking lens fixing device to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The utility model provides a double-side locking lens fixing device, aiming to solve the problem of easy loosening of the existing lens installation method proposed in the background technology.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-side locking lens fixing device, comprising a high-precision camera bracket, a mounting sleeve fixedly mounted on the high-precision camera bracket, and a threaded sleeve rotatably mounted on one end of the mounting sleeve away from the high-precision camera bracket, wherein a lens is arranged in the mounting sleeve, and a threaded groove adapted to the threaded sleeve is provided at one end of the lens connected to the mounting sleeve;

[0009] The installation sleeve is symmetrically provided with threaded openings, and a flat head screw adapted to the lens is screwed into the threaded openings.

[0010] Preferably, an anti-slip pattern is provided at one end of the flat head top screw located in the threaded opening.

[0011] Preferably, the connecting end between the lens and the mounting sleeve is symmetrically provided with grooves, and a guiding mechanism is provided in the grooves.

[0012] Preferably, the guide mechanism comprises a guide block slidably mounted in the slot and a support spring fixedly mounted between the guide block and the slot.

[0013] Preferably, an inclined portion is symmetrically provided at one end of the guide block away from the support spring.

[0014] Preferably, guide grooves adapted to the guide blocks are symmetrically provided in the installation sleeve.

[0015] (III) Beneficial effects

[0016] The double-sided locking lens fixing device has a simple structure and is easy to use. By arranging a high-precision camera bracket and a flat-head top screw, the lens is locked and fixed by the double-sided flat-head top screw. This can effectively prevent the lens from loosening due to conventional lens raw tape or glass glue locking methods during transportation, use, high and low temperature changes, and time periods. This facilitates long-term stable and accurate use of the equipment and avoids the user cost increase caused by returning the lens to the factory for repair after it becomes loose.
