Description

Technical Field

[0001] This utility model relates to the field of static pressure testing technology for springs, and in particular to a static pressure testing device for springs. Background Technology

[0002] In fields such as machinery manufacturing, automotive parts, and electronic equipment, springs, as core elastic components, directly determine the service life and operational safety of end products through their static pressure properties (such as deformation under rated load, elastic limit, and compressive strength). Therefore, static pressure testing before springs leave the factory is a crucial process for ensuring product quality, and the efficiency and accuracy of this testing have a significant impact on a company's production schedule and cost control.

[0003] Existing spring static pressure testing devices are mostly single-station designs, meaning that only one spring can be subjected to static pressure loading test at a time. In mass production scenarios, this single-station testing mode requires frequent clamping, testing, and unloading operations for individual springs, which not only consumes a lot of manual time but also causes interruptions in the testing process, resulting in low overall testing efficiency.

[0004] Therefore, it is necessary to design a static pressure testing device for springs that can test multiple springs simultaneously and quickly switch the placement plates containing springs to improve testing efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing spring static pressure testing devices, which are mostly single-station designs that can only perform static pressure loading tests on one spring at a time, and which require frequent clamping, testing, and unloading operations for individual springs in mass production scenarios, consuming a lot of manual time, interrupting the testing process, and resulting in low overall testing efficiency, this utility model provides a spring static pressure testing device that can test multiple springs simultaneously and can quickly switch the placement plate containing the springs, thereby improving testing efficiency.

[0006] The technical solution is as follows: A static pressure testing device for springs includes a base, a track, a circular arc rack, a placement plate, indicator lights, force sensors, a fixed rod, a first motor, gears, a transmission assembly, moving wheels, a connecting frame, a testing assembly, and an adjustment assembly. The base has a track connected to its upper side, and a circular arc rack connected to the inner side of the track. There are two placement plates, one in the front and one in the back, located on the track. Multiple indicator lights are connected to the upper side of each placement plate. Multiple force sensors are detachably connected to each placement plate, and a fixed rod is connected to the upper side of each force sensor. A first motor is connected to the bottom of each placement plate. Each first motor is electrically connected to a processor via a control module. Gears are connected to the output shaft of the first motor, and the placement plate meshes with the circular arc rack. A connecting frame is connected to the bottom of each placement plate, and moving wheels are rotatably connected to each connecting frame. The moving wheels are rotatably and slidably connected to the track. A transmission assembly is provided between the moving wheels and the output shaft of the first motor. A testing assembly capable of repeatedly compressing the spring is located on the upper rear part of the base. An adjustment assembly capable of adjusting the compression height according to the length of the spring is also provided on the base.

[0007] As an improvement to the above solution, multiple holes are made on each of the placement plates.

[0008] As an improvement to the above solution, a groove is provided on the inner side of the track.

[0009] As an improvement to the above solution, the transmission assembly includes a pulley and a flat belt. A pulley is connected to the lower side of the movable wheel, and a pulley is also connected to the output shaft of the first motor. A flat belt is wound between the pulleys.

[0010] As an improvement to the above solution, the test assembly includes a first connecting plate, a second motor, a disc, a connecting rod, a slide rail, and a guide rod. Multiple guide rods are connected to the upper rear part of the base, and the first connecting plate is connected between the guide rods. The second motor is connected to the upper side of the first connecting plate. The second motor and the processor are electrically connected through a control module. The disc is connected to the output shaft of the second motor. The slide rail is connected to the front side of the upper rear part of the base. The second connecting plate is slidably connected to the slide rail. The connecting rod is connected to the upper side of the second connecting plate, and the connecting rod slides in conjunction with the disc.

[0011] As an improvement to the above solution, the adjustment component includes a third motor and a lead screw. The third motor is connected to the inner side of the upper part of the base. The third motor and the processor are electrically connected through a control module. The lead screw is connected to the output shaft of the third motor and is threadedly connected to the first connecting plate.

[0012] Beneficial effects: 1. This utility model places the spring to be tested on the placement plate at the other end, then starts the first motor, and drives the moving wheel to rotate through the meshing of gears and arc racks, so that the placement plate containing the spring can be moved to the bottom of the second connecting plate. This achieves the effect of testing multiple springs at the same time and quickly switching the placement plate containing the spring, thus improving the testing efficiency.

[0013] 2. This utility model starts a third motor, which drives the lead screw to rotate, causing the first connecting plate to move up and down under the action of the thread, which in turn drives the second connecting plate to move up and down.

[0023] A static pressure testing device for springs, such as Figures 1-4 As shown, the system includes a base 1, a track 2, a circular arc rack 3, a placement plate 4, indicator lights 5, force sensors 6, fixing rods 7, a first motor 8, gears 9, a transmission assembly 10, moving wheels 11, a connecting frame 12, a testing assembly, and an adjustment assembly. The track 2 is connected to the upper side of the base 1, and the circular arc rack 3 is connected to the inner side of the track 2. There are two placement plates 4, one in the front and one in the back, located above the track 2. Each placement plate 4 has sixteen holes to allow the fixing rods 7 to pass through. Sixteen indicator lights 5 are connected to the upper side of each placement plate 4. Sixteen force sensors 6 are detachably connected to each placement plate 4. Each force sensor 6 is connected to... A fixed rod 7 is attached, and a first motor 8 is connected to the bottom of each placement plate 4. The first motor 8 is electrically connected to the processor through a control module. A gear 9 is connected to the output shaft of the first motor 8. The placement plate 4 meshes with the arc rack 3. A connecting frame 12 is connected to the bottom of each placement plate 4. A movable wheel 11 is rotatably connected to each connecting frame 12. A sliding groove is opened on the inner side of the track 2 to facilitate the movement of the movable wheel 11 along the sliding groove. The movable wheel 11 is rotatably and slidably connected to the track 2. A transmission component 10 is provided between the movable wheel 11 and the output shaft of the first motor 8. A test component is provided on the upper rear part of the base 1. An adjustment component is also provided on the base 1.

[0024] like Figure 4 As shown, the transmission assembly 10 includes a pulley and a flat belt. The lower side of the movable wheel 11 is connected to a pulley, and the output shaft of the first motor 8 is also connected to a pulley. A flat belt is wound between the pulleys.

[0025] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the test assembly includes a first connecting plate 13, a second motor 14, a disc 15, a connecting rod 16, a second connecting plate 17, a slide rail 18, and a guide rod 21. Three guide rods 21 are connected to the upper rear of the base 1, and the first connecting plate 13 is connected between the guide rods 21. The second motor 14 is connected to the upper side of the first connecting plate 13. The second motor 14 and the processor are electrically connected through a control module. The disc 15 is connected to the output shaft of the second motor 14. The slide rail 18 is connected to the front of the upper rear of the base 1. The second connecting plate 17 is slidably connected to the slide rail 18. The connecting rod 16 is connected to the upper side of the second connecting plate 17, and the connecting rod 16 slides with the disc 15.

[0026] like Figure 6As shown, the adjustment assembly includes a third motor 19 and a lead screw 20. The third motor 19 is connected to the inner side of the upper part of the base 1. The third motor 19 and the processor are electrically connected through a control module. The lead screw 20 is connected to the output shaft of the third motor 19. The lead screw 20 is threadedly connected to the first connecting plate 13.

[0027] When using this device, first place the base 1 in the spring testing area, then place the springs on the fixed rod 7. Next, the processor starts the first motor 8 via the control module, driving the gear 9 and the pulley on the transmission assembly 10 to rotate. This causes the flat belt to rotate, resulting in the gear 9 and the arc rack 3 meshing together. Simultaneously, the transmission assembly 10 drives the moving wheel 11 to rotate, moving it along the track 2. This moves the spring-loaded placement plate 4 below the second connecting plate 17. At this point, the second motor 14 is started, driving the disc 15 to rotate. This causes the connecting rod 16 to move along the disc 15, moving the second connecting plate 17 up and down along the slide rail 18. Multiple springs are repeatedly compressed, and the force sensor 6 detects the pressure. When the indicator light 5 turns green... When the indicator light is on, the spring is tested normally. When the indicator light 5 is red, the spring is faulty or has abnormal pressure. While testing the spring, the spring to be tested can be placed on the placement plate 4 at the other end. After the spring under the second connecting plate 17 is tested, the first motor 8 is started, which drives the pulley on the gear 9 and the transmission assembly 10 to rotate, so that the flat belt rotates and the gear 9 and the arc rack 3 mesh with each other. At the same time, the transmission assembly 10 drives the moving wheel 11 to rotate, so that the moving wheel 11 moves along the track 2, so that the placement plate 4 with the spring is moved to the bottom of the second connecting plate 17. Then, the second connecting plate 17 is moved up and down to test the spring. This allows multiple springs to be tested at the same time, and the placement plate 4 with the spring can be quickly switched, improving testing efficiency. When it is necessary to test springs of different lengths, the third motor 19 can be started to drive the lead screw 20 to rotate, so that the first connecting plate 13 moves up and down under the action of the thread, which drives the second connecting plate 17 to move up and down. The height of the second connecting plate 17 can be adjusted according to the length of the spring, which is convenient for testing different springs.
