[0001] The utility model relates to the field of lens strength testing, in particular to a strength detection device for vehicle-mounted lens processing. Background Art

[0002] Car lenses play a vital role in the automotive field. They can be divided into many types according to different functions and application scenarios. The rearview mirrors, anti-glare mirrors, reversing mirrors, car lenses, etc. on the car are all car lenses. As an important part of the car, the car lens not only bears the pressure from the external environment, but also needs to withstand the various vibrations and impacts inside the car. Therefore, it is very important to perform strength testing on the car lenses during processing.

[0003] When applying for this utility model, the applicant found through search that a Chinese patent disclosed "a strength detection device for vehicle-mounted lens processing", and its application number is "202122022967.8". This patent mainly tests the vehicle-mounted lenses through a pressing head, an electric suction cup and a pressure testing device, but the detection position is fixed, and the strength can only be detected at one point or a small area of ​​the lens. However, the strength of each position of the lens is not completely consistent, so the test results obtained will be different. Summary of the invention

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a strength detection device for vehicle-mounted lens processing.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a strength detection device for vehicle-mounted lens processing, comprising a base plate, a detection component fixedly connected to the upper surface of the base plate, the detection component comprising a first slide rail, a first T-shaped slider movably connected inside the first slide rail, a second slide rail fixedly connected to the top of the first T-shaped slider, a second T-shaped slider movably connected inside the second slide rail, a connecting plate fixedly connected to the front of the second T-shaped slider, a first L-shaped plate fixedly connected to the bottom of the connecting plate, an electric push rod fixedly connected to the bottom of the first L-shaped plate, a pressure sensor fixedly connected to the output end of the electric push rod, a sleeve fixedly connected to the bottom of the pressure sensor, a pressing rod installed inside the sleeve, the top of the pressing rod contacts the bottom of the pressure sensor, and a limiting ring fixedly connected to the outer surface of the pressing rod.

[0006] As a further description of the above technical solution:

[0007] A liquid crystal display is fixedly connected to the right surface of the first L-shaped plate, and the liquid crystal display is electrically connected to the pressure sensor.

[0008] As a further description of the above technical solution:

[0009] A clamping component is installed on the upper surface of the bottom plate. The clamping component includes two second L-shaped plates.

[0010] As a further description of the above technical solution:

[0011] A plurality of compression springs are fixedly connected to the right surface of the second L-shaped plate, a plurality of right ends of the compression springs are fixedly connected to stoppers, and surfaces of a plurality of adjacent stoppers are in contact with each other.

[0012] As a further description of the above technical solution:

[0013] The top of the second L-shaped plate is threadedly connected to a threaded rod, the top of the threaded rod is fixedly connected to a turntable, and the bottom of the threaded rod is fixedly connected to a push plate.

[0014] As a further description of the above technical solution:

[0015] A tension spring is fixedly connected to the lower surface of the top of the second L-shaped plate, a pressure plate is fixedly connected to the lower end of the tension spring, and the upper surface of the pressure plate is in contact with the lower surface of the push plate.

[0016] The utility model has the following beneficial effects:

[0017] 1. Compared with the prior art, the strength detection device for vehicle-mounted lens processing, through the detection component, when in use, the lens to be tested is placed in the clamping component for clamping, and the second T-shaped slider can be moved in the second slide rail by pushing the second T-shaped slider left and right, so that the pressing rod can achieve left-right displacement, and the first T-shaped slider can be moved in the first slide rail by pushing the second T-shaped slider forward and backward, so that the pressing rod can achieve forward and backward movement, when the pressing rod moves to the desired position, the electric push rod starts to work, and the pressing rod presses the lens to be tested downward, and the pressing rod will transmit the pressure signal to the pressure sensor due to the reaction force, and the liquid crystal display will display the value of the applied pressure, and the strength of the lens is detected by observing whether the lens is broken under the specified pressure. Compared with the existing device with a fixed detection position, usually only one point or a small area of ​​the lens can be tested for strength, but the strength of each position of the lens is not completely consistent, so the obtained detection results will be different, the device can move the pressing rod to any position, so as to achieve strength detection of each position of the lens, and finally the average strength of the entire lens can be calculated, and the obtained detection result is more accurate and reasonable.

[0018] 2. Compared with the prior art, this strength detection device for vehicle-mounted lens processing uses a clamping component. When in use, the blocks on both sides are pushed away and the lens to be tested is placed between the blocks on both sides. After the blocks are released, the blocks will rebound under the action of the compression springs, thereby clamping the lens to be tested. Then, the turntable is rotated to move the threaded rod downward, allowing the push plate to press the pressure plate. When the pressure plate firmly fixes the blocks, the turntable is stopped. At this time, the lens to be tested will be fixed in the specified position, which is convenient for subsequent testing. Since the vehicle-mounted lenses are irregular in shape and difficult to clamp, and the lenses cannot be fixed by directly pressing the lens body, this device can firmly fix lenses of different shapes without damaging the lenses.
