Description

Technical Field

[0001] This utility model relates to the field of fuel injector processing technology, specifically to a fuel injector component testing device. Background Technology

[0002] The function of a car fuel injector is to inject fuel into the combustion chamber at a certain pressure, speed and direction, so that the fuel is atomized into fine particles and properly distributed in the combustion chamber to facilitate the formation and combustion of the air-fuel mixture. It is an indispensable and important component in a car.

[0003] However, existing technologies still have the following problems:

[0004] Existing injector component testing devices rely heavily on manual operation or simple mechanical clamps for component fixation. Manual fixation is not only time-consuming and inefficient, but also difficult to precisely control the clamping force. This can result in either loose clamping causing component movement during testing and affecting the accuracy of the results, or excessive clamping causing damage. Simple mechanical clamps have a narrow range of applications and cannot achieve stable and secure fixation for injector components of different specifications, failing to meet the stability requirements of high-precision testing.

[0005] Furthermore, existing injector component testing devices have significant limitations in adjusting the relative position of the component and the testing mechanism. Most rely on manual adjustment, which is complex, requires considerable manpower, and has low precision, making it difficult to accurately move the component to the optimal testing position. While some devices can adjust the position, they only support simple movement in a single direction, offering extremely poor flexibility and failing to achieve multi-directional, high-precision relative position adjustments between the component and the testing plate according to the needs of different testing points. For injector components of different specifications and at different testing points, specialized testing fixtures are often required, resulting in poor versatility and significantly increasing testing costs and time.

[0006] To address the aforementioned problems, the inventors have proposed an injector component testing device. Utility Model Content

[0007] To address the issues of poor clamping and fixing of components and inconvenient adjustment of the detection structure position, the purpose of this utility model is to provide an injector component detection device.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a fuel injector component detection device, comprising a base plate, two slide rails at the upper end of the base plate, two electric sliders slidably mounted at the upper end of the slide rails, a moving plate at the upper end of the four electric sliders, two support rods fixedly mounted at the upper end of the base plate, a crossbeam fixedly mounted at the upper end of the two support rods, a motor at one end of the crossbeam, the output end of the motor passing through the crossbeam and fixedly connected to a lead screw, the two ends of the lead screw respectively connected to the inner walls of the two sides of the crossbeam, a sleeve block sleeved on the outer surface of the lead screw, two connecting plates fixedly mounted at the lower end of the sleeve block, a connecting block fixedly mounted at the lower end of the two connecting plates, an installation block at the lower end of the connecting block, and a detection plate fixedly mounted at the lower end of the installation block.

[0009] Preferably, two supports are fixedly provided on the upper end of the movable plate, a second cylinder is fixedly provided on the upper end of the movable plate, a lifting plate is fixedly provided on the output end of the second cylinder, rotating rods are rotatably provided on both sides of the upper end of the lifting plate, an L-shaped rod is rotatably provided on the outer end of each of the two rotating rods, and a fixing plate is fixedly provided on the upper side of the inner end of the L-shaped rod. The upper end of the second cylinder is lower than the upper end of the supports, and the upper end of the supports is the same as the lower end of the fixing plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model uses a clamping structure composed of a second cylinder, a rotating rod, an L-shaped rod, and a fixing plate to quickly and firmly fix the injector component to be tested, avoiding the impact of component shaking on testing accuracy during the testing process. At the same time, the fixing operation is highly automated, saving manual fixing time and improving testing efficiency.

[0012] 2. This utility model can drive the component to move flexibly in the horizontal direction through the cooperation of electric slider and slide rail. The combination of motor, lead screw and sleeve block can drive the detection plate to move precisely. The combination of the two allows the relative position between the component and the detection plate to be flexibly adjusted according to the detection requirements. It is suitable for the detection of injector components of different specifications and different detection points, and enhances the versatility of the device. Attached Figure Description

A crossbeam 21 is fixedly mounted on the upper end of the two support rods 2. A motor 22 is provided at one end of the crossbeam 21. The output end of the motor 22 passes through the crossbeam 21 and is fixedly connected to a lead screw 23. The two ends of the lead screw 23... Sleeve blocks 24 are respectively fitted onto the inner walls of both sides of the cross frame 21 and the outer surface of the lead screw 23. Two connecting plates 25 are fixedly installed at the lower end of the sleeve blocks 24. A connecting block 28 is fixedly installed at the lower end of the two connecting plates 25. An installation block 29 is installed at the lower end of the connecting block 28. A detection plate 210 is fixedly installed at the lower end of the installation block 29. The slide rail 31 is connected to the base plate 1 by bolts. The electric slider 32 is connected to the moving plate 3 by bolts. A limiting rod 211 is fixed between the inner walls of both sides of the cross frame 21. The rod 211 and the sleeve block 24 are connected through each other. The mounting block 29 has a U-shaped cross-section and is connected to the connecting block 28 by bolts. After fixing, the electric slider 32 moves along the slide rail 31, driving the moving plate 3 and the fixed components above it to adjust their positions so that they are in the appropriate detection area below the detection plate 210. Then, the motor 22 at one end of the crossbeam 21 starts, driving the lead screw 23 to rotate. The two ends of the lead screw 23 are connected to the inner walls of both sides of the crossbeam 21 respectively. The sleeve block 24 is on the lead screw 23. Under the action of the limiting rod 211, the limiting rod 211 moves smoothly between the inner walls of both sides of the cross frame 21. The two connecting plates 25 at the lower end of the sleeve block 24 move accordingly, and then drive the detection plate 210 to move through the connecting block 28 and the mounting block 29. The mounting block 29 has a U-shaped cross section and is connected to the connecting block 28 by bolts. Finally, the detection plate 210 can perform a comprehensive inspection of the fixed injector component below. The slide rail 31 and the base plate 1, and the electric slider 32 and the moving plate 3 are all connected by bolts.

[0021] Two supports 4 are fixedly mounted on the upper end of the movable plate 3. A second cylinder 41 is fixedly mounted on the upper end of the movable plate 3. A lifting plate 42 is fixedly mounted on the output end of the second cylinder 41. Rotating rods 43 are rotatably mounted on both sides of the upper end of the lifting plate 42. An L-shaped rod 44 is rotatably mounted on the outer end of each of the two rotating rods 43. A fixing plate 45 is fixedly mounted on the upper side of the inner end of each L-shaped rod 44. The two L-shaped rods 44 are mirror-image distributed. Slide grooves 48 for use with the L-shaped rods 44 are opened on both sides of the upper end of the movable plate 3. A through groove 46 is opened on the upper end of the movable plate 3. A mating groove 47 is opened on the upper end of the base plate 1.

This injector component detection device achieves accurate detection of injector components through the coordinated operation of multiple components. First, the injector component to be tested is placed on the bracket 4 of the moving plate 3. Using the driving action of the second cylinder 41, its output end pushes the lifting plate 42 to rise. During the rising process of the lifting plate 42, it drives the rotating rods 43 on both sides to rotate. The rotating rods 43 then push the L-shaped rod 44 to move inward along the sliding groove 48 on the moving plate 3. Finally, the fixed plate 45 at the upper end of the L-shaped rod 44 clamps the component to be tested, completing the fixation of the component. At this time, the through groove 46 on the moving plate 3 corresponds to the mating groove 47 on the base plate 1.

[0022] Working principle: This injector component testing device achieves accurate testing of injector components through the coordinated operation of multiple components. First, the injector component to be tested is placed on the bracket 4 of the moving plate 3. Using the driving action of the second cylinder 41, its output end pushes the lifting plate 42 to rise. During the rising process of the lifting plate 42, it drives the rotating rods 43 on both sides to rotate. The rotating rods 43 then push the L-shaped rod 44 to move inward along the sliding groove 48 on the moving plate 3. Finally, the fixing plate 45 at the upper end of the L-shaped rod 44 clamps the component to be tested, completing the fixing of the component. At this time, the through groove 46 on the moving plate 3 corresponds to the mating groove 47 on the base plate 1.

[0023] After fixing, the electric slider 32 moves along the slide rail 31, driving the moving plate 3 and the fixed components above it to adjust their positions so that they are in the appropriate detection area below the detection plate 210. Then, the motor 22 at one end of the cross frame 21 starts, driving the lead screw 23 to rotate. The two ends of the lead screw 23 are connected to the inner walls of the two sides of the cross frame 21 respectively. The sleeve block 24 moves smoothly along the limiting rod 211 under the action of the lead screw 23. The limiting rod 211 is fixed between the inner walls of the two sides of the cross frame 21. The two connecting plates 25 at the lower end of the sleeve block 24 move accordingly, and then drive the detection plate 210 to move through the connecting block 28 and the mounting block 29. The mounting block 29 has a U-shaped cross section and is connected to the connecting block 28 by bolts.
