Abstract
Description
Technical Field
[0001] The utility model belongs to the field of testing technology, and in particular relates to a novel fisheye bracket thrust testing structure. Background Art
[0002] In today's era of rapid technological development, fisheye cameras are playing an increasingly important role in many fields, from security monitoring to virtual reality, from car assisted driving to intelligent robots. Fisheye cameras, with their wide field of view and unique imaging characteristics, provide people with rich visual information.
[0003] During the production and assembly process of fisheye cameras, it is crucial to ensure the firmness of the connection between them and the bracket. Currently, the most widely used bracket assembly thrust measurement method in the fisheye camera module industry is: the thrust meter pushes down from the back of the fisheye module product, and the bracket uses a fixed base to support the bracket, which is placed directly below the pusher head. The thrust meter descends at a constant speed. When the fisheye module product is separated from the bracket, the instantaneous maximum thrust is recorded. However, some product brackets are limited by design, and the bottom of the bracket is fully enclosed, blocking the back of the fisheye module product. As a result, when testing the thrust, the pusher head cannot be subjected to force on the bottom of the product, and the thrust cannot be tested.
[0004] In view of this, the present utility model is proposed. Utility Model Content
[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a novel fisheye bracket thrust test structure, thereby solving the problems raised in the above-mentioned background technology.
[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:
[0007] A novel fisheye bracket thrust test structure includes: an adapter base plate, the top of the adapter base plate is connected to a lower clamp, the lower clamp includes a jig base plate connected to the surface of the adapter base plate, the front and rear ends of the jig base plate surface are respectively connected to a second fixed plate and a first fixed plate, and the jig base plate surface is connected to a movable plate between the first fixed plate and the second fixed plate, the front end of the movable plate is connected to a first screw, and the first screw passes through the second fixed plate and is connected to a handwheel, an upper clamp, which is located above the lower clamp, the upper clamp includes a connecting head connected to an external tensile testing machine, the bottom end of the connecting head is connected to a left clamp arm and a right clamp arm through a hook, a second screw is connected between the middle end of the left clamp arm and the middle end of the right clamp arm, and one end of the second screw is connected to a butterfly nut.
[0008] Optionally, a bracket is clamped between the first fixed plate and the movable plate, and a fisheye camera is clamped between the left clamping arm and the right clamping arm.
[0009] Optionally, a guide rail is connected to the surface of the bottom plate of the fixture between the first fixed plate and the second fixed plate, and a sliding block is connected to the top surface of the guide rail.
[0010] Optionally, the bottom end of the movable plate is fixedly connected to the sliding block.
[0011] Optionally, the front end of the movable plate is rotationally connected to the first screw rod, and the second fixed plate is threadedly connected to the first screw rod.
[0012] Optionally, the top ends of the left clamp arm and the right clamp arm are fixedly connected via a connecting shaft, the bottom end of the hook is connected to the connecting shaft, and the top end is connected to the connecting head.
[0013] Optionally, a through hole is opened at the middle end of the right clamp arm, and a rotating shaft is connected to the through hole. The right end of the second screw passes through the left clamp arm and is located at the through hole opened in the right clamp arm, and the rotating shaft passes through the right clamp arm and the right end of the second screw in sequence, and the butterfly nut is located at the left end of the second screw.
[0014] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:
[0015] 1. By testing the tensile force instead of the thrust required for bracket assembly, the problem of the thrust being unable to be tested due to the pusher head not being able to bear force on the bottom of the product is effectively avoided. This can more accurately reflect the connection strength between the fisheye camera and the bracket, providing a reliable basis for product quality assessment.
[0016] 2. By setting up a movable plate, the position of the movable plate can be adjusted to adapt to the clamping of brackets of different sizes, which makes the test structure widely applicable to brackets of various specifications, improving the versatility and practicality of the equipment;
[0017] 3. By setting a butterfly nut and rotating the butterfly nut to adjust the distance between the left clamping arm and the right clamping arm, fisheye cameras of different sizes can be clamped or loosened, further enhancing the adaptability of the equipment to different products.

DETAILED DESCRIPTION
[0029] The present invention will now be described in further detail with reference to the accompanying drawings.
[0030] See also Figure 1-5 As shown, in this embodiment, a new fisheye bracket thrust test structure is provided, including: an adapter base plate 1, a lower clamp is connected to the top of the adapter base plate 1, the lower clamp includes a jig base plate 2 connected to the surface of the adapter base plate 1, the front and rear ends of the jig base plate 2 are respectively connected to the second fixed plate 5 and the first fixed plate 4, and the surface of the jig base plate 2 is connected to a movable plate 6 between the first fixed plate 4 and the second fixed plate 5, the front end of the movable plate 6 is connected to the first screw 12, and the first screw 12 passes through the second fixed plate 5 and is connected to the handwheel 3, an upper clamp, which is located above the lower clamp, the upper clamp includes a connecting head 11 connected to an external tensile machine, the bottom end of the connecting head 11 is connected to the left clamp arm 8 and the right clamp arm 7 through a hook 10, a second screw 17 is connected between the middle end of the left clamp arm 8 and the middle end of the right clamp arm 7, and one end of the second screw 17 is connected to a butterfly nut 9.
[0031] The lower clamp can fix and clamp the bracket 16, and the movable plate 6 is driven to move toward the first fixed plate 4 by rotating the first screw 12, thereby fixing and clamping the bracket 16; the upper clamp can fix and clamp the fisheye camera 15, and the left clamping arm 8 is driven to approach the right clamping arm 7 by rotating the butterfly nut 9, so that the bottom ends of the left clamping arm 8 and the right clamping arm 7 fix and clamp the fisheye camera 15. Since the lower clamp is in a fixed state, the upper clamp is pulled to drive the left clamping arm 8 and the right clamping arm 7 to move upward, and then the tension between the fisheye camera 15 and the bracket 16 can be detected. By detecting the tension instead of the thrust that needs to be measured for assembling the bracket 16, the problem of the push head being unable to bear the force at the bottom of the product and being unable to test the thrust is avoided.
[0032] In this embodiment, a bracket 16 is clamped between the first fixed plate 4 and the movable plate 6, and a fisheye camera 15 is clamped between the left clamping arm 8 and the right clamping arm 7. By adjusting the position of the movable plate 6, brackets 16 of different sizes can be clamped. The left clamping arm 8 and the right clamping arm 7 of the upper clamp ensure that the position of the fisheye camera 15 is stable during the test, and at the same time, it is convenient to pull the fisheye camera 15.
[0033] A guide rail 13 is connected to the surface of the jig base plate 2 between the first fixed plate 4 and the second fixed plate 5, and a sliding block 14 is connected to the top surface of the guide rail 13. The guide rail 13 provides a moving track for the sliding block 14 to ensure the direction and stability of movement. The bottom end of the movable plate 6 is fixedly connected to the sliding block 14. The movable plate 6 can slide smoothly on the guide rail 13 through the sliding block 14 to adjust the clamping position of the bracket 16.
[0034] The front end of the movable plate 6 is rotatably connected to the first screw 12, and the second fixed plate 5 is threadedly connected to the first screw 12. When the first screw 12 is rotated, since the second fixed plate 5 is threadedly connected to the first screw 12, the rotational motion of the first screw 12 is converted into linear motion, pushing the movable plate 6 to move on the guide rail 13.
[0035] The top ends of the left clamping arm 8 and the right clamping arm 7 are fixedly connected by a connecting shaft. The connecting shaft makes the left clamping arm 8 and the right clamping arm 7 form a whole at the top to ensure the stability of the clamping. The bottom end of the hook 10 is connected to the connecting shaft, and the top end is connected to the connecting head 11. The hook 10 serves to connect the upper clamp and the external tensile machine, and transmits the tension from the connecting head 11 to the left clamping arm 8 and the right clamping arm 7. A through hole is opened in the middle end of the right clamping arm 7, and a rotating shaft 18 is connected in the through hole. The right end of the second screw 17 is penetrated The left clamping arm 8 is passed through the through hole opened in the right clamping arm 7, and the rotating shaft 18 passes through the right clamping arm 7 and the right end of the second screw 17 in sequence. The butterfly nut 9 is located at the left end of the second screw 17. The rotating shaft 18 connects the second screw 17 to the right clamping arm 7 while ensuring that the second screw 17 can rotate. By rotating the butterfly nut 9, the position of the second screw 17 can be adjusted, thereby changing the distance between the left clamping arm 8 and the right clamping arm 7, thereby achieving the clamping or loosening of the fisheye camera 15.
[0036] Working principle:
[0037] The second screw 17 is rotated at the through hole of the right clamping arm 7, and the second screw 17 is rotated at the through hole of the right clamping arm 7. At the same time, the left clamping arm 8 is pushed closer to the right clamping arm 7, and the bottom ends of the left clamping arm 8 and the right clamping arm 7 fix the fisheye camera 15.
[0038] Finally, start the external tensile testing machine, and the connecting head 11 of the upper clamp is connected to the external tensile testing machine. The hook 10 transfers the tension from the connecting head 11 to the left clamp arm 8 and the right clamp arm 7. The external tensile testing machine pulls the upper clamp, driving the left clamp arm 8 and the right clamp arm 7 to move upward. Since the fisheye camera 15 is clamped by the upper clamp and the bracket 16 is clamped by the lower clamp, the upward movement of the upper clamp will generate a pulling force between the fisheye camera 15 and the bracket 16. By detecting this pulling force, the thrust that needs to be measured can be replaced by assembling the bracket 16, avoiding the problem that the push head cannot be subjected to force at the bottom of the product and cannot test the thrust.
[0039] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention. The technology, shape, and structure not described in detail in the present invention are all known technologies.
