[0033] Reference Figure 5 The workbench 1 is provided with a semicircular shield at the position of the rotating groove 9, and a reading hole 93 is opened on the shield; the inspector can directly read the scale on the scale ring 92 through the reading hole 93. This design makes the test result more intuitive and accurate.
[0034] Reference Figure 1 A placement table 10 is fixedly provided at the side wall of the fixed arm 2, which can ensure full support for the glasses as a whole.
[0035] The specific working principle of the utility model is as follows:
[0036] When in use, the two ends of the temples are placed in the space where the two semicircular blocks 55 on the fixed arm 2 and the bending arm 3 are opposite to each other, and the two semicircular blocks 55 are pinched by hand to move inwards, and the semicircular blocks 55 drive the mounting plate 54 and the guide plate 52 to move inwards. When the guide plate 52 drives the rack 521 to move inwards, the rack 521 on one side drives the gear 53 meshing therewith to rotate, and then drives the rack 521 on the other side to move relative to it, and always keeps the clamping position of the two semicircular blocks 55 constant on the central axis, ensuring that no torsional stress is generated on the temples due to the non-collinear clamping directions of the two ends of the temples. When the circular clamping block 57 contacts the temples, it can drive the arc block 56 and the semicircular block 55 to rotate relative to their own axes, so as to adapt to the original curvature of the temples and realize the clamping of temples of different models and curves.
[0037] When the two semicircular blocks 55 are pinched together to clamp the legs of the glasses, the slider 63 first contacts the inclined surfaces opposite to the locking block 64, and under the guidance and pushing action of the inclined surfaces of the locking block 64, the slider 63 slides upward along the guide column 62 to compress the compression spring 65. Under the action of the compression spring 65, the slider 63 and the locking block 64 are always in contact with each other. After the matching limiting teeth 641 arranged on the inclined surfaces contact, when the slider 63 and the locking block 64 are separated, the vertical surfaces are engaged with each other, and together with the compression spring 65, they play a locking role. The tester only needs to pinch it to complete the automatic locking of the sample. When it is necessary to take off the glasses, the pull rod 66 is pulled to drive the slider 63 to move upward and separate from the locking block 64. Under the action of the return spring 68, the guide plate 52 moves away from the baffle 67, and the two semicircular blocks 55 are automatically separated to release the glasses legs. At this time, the glasses legs can be conveniently taken off. The above structure does not require complicated manual operations to lock and release the clamp. According to the difference in the length of the glasses legs, the screw 32 can be rotated to drive the mounting seat 5 to move in the adjustment slot 31, so as to adjust the distance between the clamped glasses legs to meet different products and different testing requirements.
[0038] When bending the temple, the system rotates slowly. At this time, a certain distance is maintained between the movable claw 83 and the ratchet 84, so that the temple can pass smoothly. When the temple is bent to the limit angle, the temple will break, causing the rotating block 4 to rotate rapidly due to inertia. At the moment of rotation, the movable claw 83 maintains its original position due to inertia. While the mounting plate 81 maintains the rotation trend, the movable claw 83 extends outward and contacts the ratchet 84. Under the action of the ratchet 84, the rotating block 4 and the bending arm 3 are stopped urgently, ensuring that the bending arm 3 maintains the angle when it is bent and broken. When the recording is completed, when the servo motor 7 is reversed and reset, the movable claw 83 is reset by the inclined surface guide of the ratchet 84 during rotation, so that it can maintain normal operation in the next test.
[0039] During the test, the bending arm 3 drives the scale ring 92 to rotate in the rotating groove 9. The scale of the scale ring 92 corresponding to the reading hole 93 at the starting position is "0°". After that, after rotation, the tester can directly read the scale on the scale ring 92 through the reading hole 93, that is, the bending angle. The placement table 10 can be used to support the lens part of the glasses to avoid axial torsion of the temples due to insufficient support of the glasses as a whole, which affects the accuracy of the test results.
[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
