Description

Technical Field

[0001] The utility model relates to the technical field of ignition coil test benches, in particular to an ignition coil test bench frame. Background Art

[0002] With the development of automotive gasoline engines towards high speed, high compression ratio, high power, low fuel consumption and low emissions, traditional ignition devices have become unsuitable for use requirements. When detecting, it is necessary to connect the spark plug and the pin plug of the ignition coil. The core components of the ignition device are the ignition coil and the switching device. By increasing the energy of the ignition coil, the spark plug can generate a spark with sufficient energy, which is the basic condition for the ignition device to adapt to the operation of modern engines. Ignition coils are divided into two types according to the magnetic circuit: open magnetic type and closed magnetic type. Traditional ignition coils use the open magnetic type, and their iron cores are stacked with silicon steel sheets about 0.3 mm thick. Secondary and primary coils are wound on the iron core. The closed magnetic type uses an iron core shaped like III to wind the primary coil, and then the secondary coil is wound outside. The magnetic lines of force form a closed magnetic circuit by the iron core. The advantages of the closed magnetic type ignition coil are less magnetic leakage, less energy loss and smaller volume. Therefore, the closed magnetic type ignition coil is generally used in electronic ignition systems. A test bench is required for the test of ignition coils.

[0027] As Figures 1 to 4 shown, an ignition coil test bench includes a test bench body 1. A sliding frame 2 is fixedly connected to the top of the test bench body 1. Opposite slide rails 3 are fixedly connected to one side of the sliding frame 2. A support plate 4 is slidably connected between the opposite slide rails 3. Slide blocks 5 are fixedly connected to both sides of the support plate 4. The slide blocks 5 are respectively slidably connected to the side walls of the slide rails 3. Three clamping mechanisms for fixing the ignition coil are arranged on the side wall of the support plate 4. A detection mechanism for automatically detecting the ignition coil is arranged on the side wall of the sliding frame 2.

[0028] Further, referring to the attachedFigure 2 and Figure 3 As shown in Figure 3 , the three clamping mechanisms include fixed bases 6 fixedly connected inside the support plate 4. Fixed blocks 7 are fixedly connected to four surfaces of the fixed base 6. Clamping rotating rods 8 are rotatably connected to the tops of the fixed blocks 7. Clamping blocks 9 are rotatably connected to the tops of the clamping rotating rods 8. One ends of the clamping blocks 9 are fixedly connected to clamping plates 10. A downward sliding rod 11 is slidably connected through the middle part of the fixed base 6. A compression spring 12 is sleeved on the outer wall of the downward sliding rod 11. A pulling block 13 is fixedly connected to the outer wall of the downward sliding rod 11. One end of the compression spring 12 is fixedly connected to the top of the fixed base 6, and the other end of the compression spring 12 is fixedly connected to the bottom of the pulling block 13. Pulling rods 14 are rotatably connected between the pulling block 13 and the clamping rotating rods 8. A placing table 15 is fixedly connected to the top of the downward sliding rod 11;

[0029] When the clamping mechanism is in use, first, the staff places the ignition coil to be detected on the top of the placing table 15. Subsequently, the placing table 15 will move downward under the gravity of the ignition coil and squeeze the downward sliding rod 11. The downward sliding rod 11 drives the pulling block 13 to move downward when being squeezed. When the pulling block 13 is squeezed, it will pull one end of the pulling rod 14 to rotate downward. Subsequently, the pulling rod 14 will pull the clamping rotating rod 8 at the other end. When the clamping rotating rod 8 is pulled by the pulling rod 14, it will drive the clamping block 9 to approach the ignition coil. When the clamping block 9 approaches, it will drive the ignition coil to move and clamp all four surfaces of the ignition coil, avoiding the situation of falling during the moving detection. There is no need for the staff to manually fix and clamp. Multiple ignition coils can be clamped and detected, saving time and effort, improving the detection efficiency, and being convenient to use.

[0030] Further, as shown in Figure 2 and Figure 4 As shown in Figure 4 , the detection mechanism includes a test support plate 16 slidably connected to the side wall of the sliding frame 2. Three test rods 23 are fixedly connected to the top of the test support plate 16. One ends of the test rods 23 extend into the spark plugs of the ignition coil. A spring support plate 17 is fixedly connected between the side walls of the sliding frame 2. A telescopic spring 18 is fixedly connected between the support plate 4 and the spring support plate 17. An electric telescopic rod 19 is fixedly connected to the top of the spring support plate 17, and the other end of the electric telescopic rod 19 is fixedly connected to the test support plate 16. First guide wheels 20 are rotatably connected to one side of the top of the sliding frame 2. Second guide wheels 21 are rotatably connected to the opposite inner surfaces of the spring support plate 17. An elastic pull rope 22 is fixedly connected between the side walls of the support plate 4 and the test support plate 16. The elastic pull rope 22 is made of an elastic material, and the outer part of the elastic pull rope 22 is in contact with the outer walls of the first guide wheels 20 and the second guide wheels 21 respectively;

[0031] When the testing mechanism is in use, first turn on the power supply and start the electric telescopic rod 19. When the electric telescopic rod 19 contracts, it will drive the test support plate 16 to slide downward in the sliding frame 2. When the test support plate 16 slides, it will drive the test rod 23 to move. At this time, the test support plate 16 will also pull the elastic pull rope 22. The other end of the support plate 4 will be pulled under the action of the tensile force. The support plate 4 will slide on the slide rail 3 and compress the telescopic spring 18 under the action of the tensile force of the elastic pull rope 22. Subsequently, the support plate 4 will drive the clamped ignition coil to move to the bottom of the test rod 23 and make contact with the limit block 25. The test rod 23 and the spark plug on the ignition coil are on the same horizontal plane. At this time, the test plug 24 will be inserted into the pin jack on the side wall of the ignition coil. Subsequently, the electric telescopic rod 19 drives the test support plate 16 to continue to move downward. Then, the test rod 23 is inserted into the spark plug of the ignition coil. Then, the test rod 23 and the test plug 24 are started. The detected data is connected to the test bench body 1 through the connecting wire by the test rod 23 and the test plug 24 and transmitted to the test bench body 1. Subsequently, the staff can detect whether there are faults in these ignition coils, which saves time and effort. The test bench body 1 can test multiple ignition coils at the same time, greatly improving the test efficiency, meeting the needs of mass production and testing. The test process realizes high automation, reduces the steps and difficulty of manual operation, reduces the risk of human misoperation, ensures the stability and reliability of the test process, and improves the detection efficiency.

[0032] Further, referring to the attached Figure 2 As shown, between the side walls of the sliding frame 2, three test plugs 24 are fixedly connected near the top of the spring support plate 17. One end of the test plug 24 extends into the pin jack of the ignition coil. The test plug 24 is used to connect with the pin jack on the side wall of the ignition coil, facilitating the detection of the ignition coil.

[0033] Further, referring to the attached Figure 4 As shown, opposite limit blocks 25 are fixedly connected to the opposite surfaces of the sliding frame 2. One end of the elastic pull rope 22 passes through the limit block 25, and the limit block 25 is used to limit the support plate 4.

[0034] Further, referring to the attached Figure 3 As shown, the shape of the clamping plate 10 is arc-shaped and the side wall of the clamping plate 10 is provided with corrugations. The clamping plate 10 and the provided corrugations are used to increase the friction between the ignition coil and the clamping plate 10.
