It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of embodiments.
[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0026] Example 1
[0027] Please see Figure 1-7In this embodiment, a helical spring length detection device is provided, including: a base 1, a tooling bracket 3 fixedly connected to the top of the base 1, a control box 2 provided on one side of the base 1, a spring 6 to be detected provided above the base 1, and a bracket 5 fixedly connected to the top of the base 1; a clamping assembly provided on the top of the base 1, the clamping assembly including: the tooling bracket 3, a limiting plate 4, a slider 402, a guide rail 403, and a spring 503; and a detection assembly provided between the control box 2 and the tooling bracket 3, the detection assembly including: a distance sensor 501, a red indicator light 201, a green indicator light 203, and a buzzer 202.
[0028] The detection components enable staff to quickly determine whether the spring 6 under test is qualified by turning on and off the buzzer 202, the red indicator light 201 and the green indicator light 203, thereby improving detection efficiency and reducing the risk of misjudgment.
[0029] Secondly, by setting up the clamping components, it can be ensured that the contact positions of the two ends of the spring 6 under test are consistent during each measurement, avoiding detection errors caused by positioning deviations, and also facilitating the clamping of the spring 6 under test.
[0030] Example 2
[0031] Based on Embodiment 1, the tooling bracket 3 has a positioning slot 301 on its top, the base 1 has a guide rail 403 fixedly connected to its top, the guide rail 403 has a slider 402 slidably connected to its top, the slider 402 has a limit plate 4 fixedly connected to its top, the limit plate 4 has a spring limit groove a404 on one side, and a spring 503 is fixedly connected inside the spring limit groove a404; the bracket 5 has a spring limit groove b502 on one side, one end of the spring 503 extends into the spring limit groove b502 and is fixedly connected to the bracket 5; the guide rail 403 has a limit rod 405 on both sides, and the limit plate 4 has a slot 401 on one side; a spring 6 to be tested is provided between the tooling bracket 3 and the limit plate 4, and a limit groove 601 is provided at one end of the spring 6 to be tested.
[0032] In use, the user can take out the spring 6 to be tested, insert one end of the spring 6 with the limiting groove 601 into the positioning slot 301 at the top of the tooling bracket 3, and then abut the other end of the spring 6 against one side of the groove 401. Since the spring 6 has a certain rigidity, it will push the limiting plate 4, causing the slider 402 to slide on the guide rail 403, thereby compressing the spring 503 and placing the spring 6 between the tooling bracket 3 and the limiting plate 4. When released, the spring 503 is released and will push the limiting plate 4 and the slider 402 to slide on the guide rail 403, thereby pushing the spring 6 to move away from the bracket 5. This will cause one end of the spring 6 to move in the positioning slot 301, so that the end of the stroke of the limiting groove 601 moves to one side of the tooling bracket 3 and abuts against one side of the tooling bracket 3, thus completing the fixing of the spring 6.
[0033] Example 3
[0034] Based on Embodiment 1, a distance sensor 501 is fixedly connected to the top of the bracket 5, a red indicator light 201 is fixedly installed on one side of the control box 2, a green indicator light 203 is fixedly installed on one side of the control box 2, a buzzer 202 is fixedly installed on one side of the control box 2, and a microcontroller is installed inside the control box 2.
[0035] When the spring 6 to be tested is fixed between the tooling bracket 3 and the limiting plate 4, the distance sensor 501 will detect the change in distance between itself and the limiting plate 4. The distance sensor 501 will convert the detected distance data into an electrical signal and transmit it to the microcontroller inside the control box 2. Then, the microcontroller inside the control box 2 will process the data according to the preset judgment logic. When the distance sensor 501 detects that the distance to the object is less than or greater than the preset threshold, it will trigger the conditional green indicator light 203 or red indicator light 201 and the buzzer 202.
[0036] When the spring 6 to be tested is fixed between the tooling bracket 3 and the limit plate 4, and the spring 6 to be tested is qualified, the distance sensor 501 generates an electrical signal and transmits it to the microcontroller inside the control box 2. The microcontroller activates the green indicator light 203. At this time, the operator can judge that the spring 6 to be tested is a qualified product by turning on the green indicator light 203.
[0037] When the spring 6 to be tested is unqualified, the distance sensor 501 generates an electrical signal and transmits it to the microcontroller inside the control box 2. The microcontroller then activates the red indicator light 201 and the buzzer 202. At this time, the staff can determine that the spring 6 to be tested is an unqualified product by using the activated red indicator light 201 and the buzzer 202.
[0038] The control program involved in this utility model can be implemented by those skilled in the art based on the same or similar principles in the prior art, and this part is not the innovation of this utility model.
