Description

Technical Field

[0001] The utility model relates to the technical field of aging test benches for instrument testing, and particularly relates to an aging test bench for instrument testing. Background Art

[0002] An aging test bench for instrument testing is a device specifically used for aging tests on electronic products such as electronic instruments, sensors, and controllers. Aging tests are an important part of the reliability tests of electronic products, aiming to simulate the performance of products under long-term use or extreme environmental conditions, evaluate their stability and lifespan. Through such tests, manufacturers can discover potential defects in product designs, optimize production processes, and improve the overall quality of products.

[0003] During the use of the current aging test bench for instrument testing, staff often find that: the current aging test bench for instrument testing usually only simulates situations such as high temperature, low temperature, and humidity. However, instrument panels are usually installed in automobiles and will vibrate continuously during the driving of the automobile. If the instrument panel is assembled without vibration test detection before automobile assembly, it is easy to cause damage to the instrument panel during the driving of the automobile. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose an aging test bench for instrument testing.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: an aging test bench for instrument testing, including a test box body, a door panel is rotatably connected to the test box body, two placement plates are arranged on the test box body, a vibration structure is arranged on the test box body, the vibration structure mainly consists of two sliding grooves, both of the two sliding grooves are opened on both sides of the test box body, and the sliding grooves are slidably connected to the placement plates.

[0006] The effects achieved by the above components are as follows: Place the instrument to be tested on the placement plate, and then slide the placement plate back and forth, so that the placement plate drives the instrument to vibrate, thus avoiding the situation that since the instrument panel is usually installed in an automobile and will vibrate continuously during the driving of the automobile, if the instrument panel is assembled without vibration test detection before automobile assembly, it is easy to cause damage to the instrument panel during the driving of the automobile.

[0007] Preferably, a first spring is fixedly connected to the inner wall of the sliding groove, and one end of the first spring is fixedly connected to the placement plate.

[0008] The effects achieved by the above components are as follows: sliding the two placement plates to the right will cause the placement plates to squeeze the first spring and contract. When released randomly, the placement plates will rebound under the action of the elastic force of the first spring.

[0009] Preferably, a sliding rod is fixedly connected to the placement plate. The sliding rod is slidably inserted into the main body of the test box, and a rectangular block is fixedly connected to one end of the sliding rod.

[0010] The effects achieved by the above components are as follows: the staff can drive the placement plate to slide by sliding the sliding rod, making the operation more convenient.

[0011] Preferably, two cams are provided on the main body of the test box. The cams are fixedly connected to the connecting rod. A fixed plate is fixedly connected to the main body of the test box, and a first motor is fixedly connected to the fixed plate. A connecting rod is fixedly connected to the output shaft of the first motor.

[0012] The effects achieved by the above components are as follows: starting the first motor, the output shaft of the first motor drives the connecting rod to rotate, and then drives the two cams to rotate. When the major diameter of the cam contacts the placement plate, it will push the placement plate to slide to the right, squeezing the first spring to contract. When the major diameter of the cam moves away from the placement plate, the placement plate will reset under the action of the elastic force of the first spring. Repeating this process can improve the vibration effect.

[0013] Preferably, a limiting structure is provided on the placement plate. The limiting structure mainly consists of two sliding grooves. Both sliding grooves are opened on the placement plate, and two clamping plates are slidably connected together on the two sliding grooves.

[0014] The effects achieved by the above components are as follows: placing the instrument on the placement plate and sliding the two clamping plates to clamp the instrument can prevent the instrument from shaking and hitting randomly during the detection process and being damaged.

[0015] Preferably, a bidirectional screw is rotatably connected in one of the sliding grooves. The two sections of threads on the bidirectional screw have opposite directions, and the bidirectional screw is threadedly connected to the two clamping plates.

[0016] The effects achieved by the above components are as follows: since the two clamping plates are limited and slide in the sliding grooves, rotating the bidirectional screw can drive the two clamping plates to slide synchronously and in opposite directions, making the clamping more stable.

[0017] Preferably, a second motor is fixedly connected to the placement plate. The output shaft of the second motor is fixedly connected to the bidirectional screw.

[0018] The effects achieved by the above components are as follows: starting the second motor, the output shaft of the second motor drives the bidirectional screw to rotate, making the operation more convenient.

[0019] Preferably, a rubber block is fixedly connected to one of the clamping plates. Two telescopic rods are fixedly connected to the rubber block. The telescopic rods are fixedly connected to the clamping plates. A second spring is sleeved on the telescopic rods. One end of the second spring is fixedly connected to the clamping plate, and the other end of the second spring is fixedly connected to the rubber block.

[0020] The effects achieved by the above components are as follows: The rubber block can deform during clamping, which can better cope with the arc side of the instrument, making the clamping more stable. When the rubber block is squeezed, the telescopic rods and the second spring will contract, and the elastic force of the second spring acting on the rubber block can further improve the clamping effect.

[0021] Compared with the prior art, the advantages and positive effects of the present invention are as follows: In the present invention, by setting a vibration structure, the instrument to be tested is placed on the placement plate, and then the placement plate is slid back and forth, so that the placement plate drives the instrument to vibrate. When the two placement plates are slid to the right, the placement plate will squeeze the first spring to contract. Then, when released randomly, the placement plate will reset and rebound under the action of the elastic force of the first spring. The staff can drive the placement plate to slide by sliding the sliding rod, making the operation more convenient. When the first motor is started, the output shaft of the first motor drives the connecting rod to rotate, and then drives the two cams to rotate. When the long diameter of the cam contacts the placement plate, it will push the placement plate to slide to the right, squeezing the first spring to contract. When the long diameter of the cam moves away from the placement plate, the placement plate will reset under the action of the elastic force of the first spring. Repeating this process can improve the vibration effect, thus avoiding the situation that because the instrument panel is usually installed in a car and vibrates during the driving of the car, the instrument panel will always work with the vibration of the car. If the instrument panel is assembled without vibration test and detection before the car assembly, it is easy to cause damage to the instrument panel during the driving of the car.

Detailed implementation mode

[0027] Example 1, as Figure 1 and Figure 2 shown, an aging test bench for instrument testing includes a test chamber body 1, a door panel 2 is rotatably connected to the test chamber body 1, and two placing plates 3 are arranged on the test chamber body 1.

[0028] Referring to Figure 3 , a vibration structure 4 is arranged on the test chamber body 1. The vibration structure 4 mainly consists of two slide grooves 41. The two slide grooves 41 are both opened on both sides of the test chamber body 1. The slide grooves 41 are slidably connected to the placing plate 3. Place the instrument to be tested on the placing plate 3, and then slide the placing plate 3 back and forth, so that the placing plate 3 drives the instrument to vibrate, thus avoiding the situation that because the instrument panel is usually installed in a car and vibrations will occur during the driving of the car, the instrument panel will always work with the vibrations of the car. If the instrument panel is assembled without vibration test detection before car assembly, it is easy to cause damage to the instrument panel during the driving of the car. A first spring 43 is fixedly connected to the inner wall of the slide groove 41, and one end of the driving first spring 43 is fixedly connected to the placing plate 3. Slide the two placing plates 3 to the right, which will cause the placing plate 3 to squeeze the first spring 43 to contract. Then release the hand randomly, and the placing plate 3 will reset and rebound under the action of the elastic force of the first spring 43 rebounding. A slide rod 44 is fixedly connected to the placing plate 3. The slide rod 44 is slidably inserted into the test chamber body 1. One end of the slide rod 44 is fixedly connected to a rectangular block 45. The staff can drive the placing plate 3 to slide by sliding the slide rod 44, making the operation more convenient. Two cams 46 are arranged on the test chamber body 1. The cams 46 are fixedly connected to the connecting rod 48. A fixed plate 42 is fixedly connected to the test chamber body 1. A first motor 47 is fixedly connected to the fixed plate 42. A connecting rod 48 is fixedly connected to the output shaft of the first motor 47. Start the first motor 47, and the output shaft of the first motor 47 drives the connecting rod 48 to rotate, thereby driving the two cams 46 to rotate. When the long diameter of the cam 46 contacts the placing plate 3, it will push the placing plate 3 to slide to the right, squeezing the first spring 43 to contract. When the long diameter of the cam 46 moves away from the placing plate 3, the placing plate 3 will reset under the action of the elastic force of the first spring 43 rebounding. Repeating this process can improve the vibration effect.

[0029] Referring to Figure 4, a limiting structure 5 is provided on the placing plate 3. The limiting structure 5 mainly consists of two sliding grooves 51. Both of the two sliding grooves 51 are opened on the placing plate 3. Two clamping plates 52 are slidably connected together on the two sliding grooves 51. Place the instrument on the placing plate 3 and slide the two clamping plates 52 to clamp the instrument, which can prevent the instrument from being damaged due to random shaking and impact during the detection process. A bidirectional screw 53 is rotatably connected in one sliding groove 51. The two threaded sections on the bidirectional screw 53 have opposite thread directions. The bidirectional screw 53 is threadedly connected to the two clamping plates 52. Since the two clamping plates 52 are limited and slide in the sliding groove 51, rotating the bidirectional screw 53 can drive the two clamping plates 52 to slide synchronously and in opposite directions, making the clamping more stable. A second motor 55 is fixedly connected to the placing plate 3. The output shaft of the second motor 55 is fixedly connected to the bidirectional screw 53. Start the second motor 55, and the output shaft of the second motor 55 drives the bidirectional screw 53 to rotate, making the operation more convenient. A rubber block 54 is fixedly connected to one clamping plate 52. Two telescopic rods 56 are fixedly connected to the rubber block 54. The telescopic rods 56 are fixedly connected to the clamping plate 52. A second spring 57 is sleeved on the telescopic rods 56. One end of the second spring 57 is fixedly connected to the clamping plate 52, and the other end of the second spring 57 is fixedly connected to the rubber block 54. The rubber block 54 can deform during clamping, which can better cope with the arc-shaped side of the instrument, making the clamping more stable. Moreover, when the rubber block 54 is squeezed, the telescopic rods 56 and the second spring 57 will contract, and the elastic force of the second spring 57 acting on the rubber block 54 can further improve the clamping effect.

[0030] Working principle: Place the instrument to be tested on the placement plate 3, and then slide the placement plate 3 back and forth, so that the placement plate 3 drives the instrument to vibrate. This avoids the situation that since the instrument panel is usually installed in a vehicle and vibrations will occur during the vehicle's driving, the instrument panel will always work with the vehicle's vibrations. If the vibration test of the instrument panel is not carried out before vehicle assembly and then assembly is carried out, it is easy to cause damage to the instrument panel during the vehicle's driving. Slide the two placement plates 3 to the right, which will cause the placement plates 3 to squeeze the first spring 43 to contract. Then release the hand randomly, and the placement plates 3 will reset and rebound under the action of the rebounding elastic force of the first spring 43. The staff can drive the placement plates 3 to slide by sliding the slide bar 44, making the operation more convenient. Start the first motor 47, the output shaft of the first motor 47 drives the connecting rod 48 to rotate, and then drives the two cams 46 to rotate. When the long diameter of the cam 46 contacts the placement plate 3, it will push the placement plate 3 to slide to the right, squeezing the first spring 43 to contract. When the long diameter of the cam 46 moves away from the placement plate 3, the placement plate 3 will reset under the action of the rebounding elastic force of the first spring 43. Repeating this process can improve the vibration effect. Place the instrument on the placement plate 3, and slide the two clamping plates 52 to clamp the instrument, which can prevent the instrument from shaking and hitting randomly and being damaged during the detection process. Since the two clamping plates 52 are limited to slide in the sliding groove 51, rotating the bidirectional screw 53 can drive the two clamping plates 52 to slide synchronously and reversely, making the clamping more stable. Start the second motor 55, the output shaft of the second motor 55 drives the bidirectional screw 53 to rotate, making the operation more convenient. The rubber block 54 can deform during clamping, which can better handle the arc side of the instrument, making the clamping more stable. And when the rubber block 54 is squeezed, the telescopic rod 56 and the second spring 57 will contract, and the rebounding elastic force of the second spring 57 acts on the rubber block 54, which can further improve the clamping effect.
