DETAILED DESCRIPTION

[0028] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples.

[0029] Refer to the attached Figure 1 to Figure 2 As shown, the optical glass impact test device of this embodiment includes a base 1, a first slide 2, a second slide 3, an energy storage component 13 and a trigger component. The specific structure and connection relationship of each component are described as follows:

[0030] The base 1 is a rectangular base body, and a first dovetail guide groove 101 is provided on the upper surface of the base 1 along the long axis direction of the base 1, and a first dovetail convex block is provided at the bottom of the first slide 2 along the long axis direction. The first slide 2 forms a sliding connection with the base 1 along the horizontal direction through the cooperation between the first dovetail convex block and the first dovetail guide groove 101. A carrier 14 for placing the optical glass 15 to be tested is provided at one end of the base 1, and a wedge-shaped top block 4 is provided at one end of the first slide 2 relative to the carrier 14.

[0031] The carrier 14 is provided with a placement slot from top to inside, and the optical glass is inserted into the placement slot from top, and the placement slot has a circular opening smaller than the outer diameter of the optical glass facing the first slide 2, so that the impact hammer 5 can impact the optical glass 15 to be tested. The placement slot is exposed at the top of the optical glass 15 to be tested, which is convenient for taking and placing the optical glass 15 to be tested.

[0032] Of course, in order to realize the horizontal movement of the first slide 2 on the base 1, a driving component for driving the movement of the first slide 2 is provided on the base 1, and the driving component includes a motor 10, a gear 11 and a rack 12. The rack 12 is integrally formed on one side of the first slide 2, and the gear 11 is connected to the side wall of the base 1 through a bearing between the wheel axle and the side wall of the base 1. The gear 11 is meshed with the rack 12. The motor 10 is fixed to the side wall of the base 1 through a mounting plate, and the output end of the motor 10 is transmission-connected to the gear 11, so that the reciprocating motion of the first slide 2 is realized through the forward and reverse rotation of the motor 10.

[0033] In this embodiment, the upper surface of the first slide 2 is provided with a second dovetail guide groove 202 which is in the same direction as the first dovetail guide groove 101, and the bottom of the second slide 3 is provided with a second dovetail protrusion which matches the second dovetail guide groove 202. The second slide 3 forms a sliding connection with the first slide 2 through the cooperation of the second dovetail guide groove 202 and the second dovetail protrusion 301. The second slide 3 is provided with an impact hammer 5 on the side close to the carrier 14, and a stop block 6 is provided on the side close to the wedge-shaped top block 4 of the second slide 3.

[0034] The energy storage member 13 is arranged between the wedge-shaped top block 4 and the second slide 3. Specifically, the energy storage member 13 includes a guide column 1301 and a spring 1302, one end of the guide column 1301 is fixedly connected to the second slide 3, the other end of the guide column 1301 slides through the wedge-shaped top block 4, a limiting nut 1303 is arranged at one end of the guide column 1301 that passes through the wedge-shaped top block 4, and the spring 1302 is sleeved on the guide column 1301 between the second slide 3 and the wedge-shaped top block 4.

[0035] At the same time, the trigger member includes a bracket 8 mounted on the base 1, the bracket 8 includes a pillar and a transverse axis, the pillar mounts the transverse axis on the base 1, and a trigger rod 9 coaxial with the second slide 3 is rotatably provided on the bracket 8 through a bearing connection, and a wedge-shaped trigger head 901 matching the inclined surface of the wedge-shaped top block 4 is provided at the end of the trigger rod 9 away from the bracket 8, and a stop buckle 7 that abuts against the stop block 6 is provided at the bottom of the trigger rod 9.

[0036] The working principle of the optical glass impact test device in this embodiment is as follows:

[0037] First, insert the optical glass 15 to be tested into the placement slot of the stage 14;

[0038] Then, the motor 10 is started to rotate forward. The motor 10 drives the first slide 2 to move toward the side of the platform 14 through the engagement of the gear 11 and the rack 12. At this time, the second slide 3 is blocked by the block 6 and the buckle 7 and cannot move with the first slide 2. Therefore, as the first slide 2 moves toward the side of the platform 14, the spring 1302 is compressed and stores energy. When the first slide 2 continues to move toward the side of the platform 14 until the wedge-shaped top block 4 contacts the wedge-shaped trigger head 901, as the first slide 2 continues to move, the trigger rod 9 is lifted. At this time, the block 6 and the buckle 7 are separated, and the compressed spring 1302 releases energy and recovers its original length due to the loss of obstruction, pushing the second slide 3 forward, so that the second slide 3 moves toward the side of the platform 14 and hits the optical glass 15 to be tested in the front platform 14, thereby completing the impact experiment.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
