Description

Technical Field

[0001] This utility model relates to the field of high-pressure oil rail detection technology, and in particular to a high-pressure oil rail detection mechanism. Background Technology

[0002] The high-pressure fuel rail is a key component of the fuel supply system for diesel engines. It is typically a sealed metal pipe that is installed on the engine and connected to the fuel injector. Its main function is to deliver fuel from the fuel pump to the fuel injector. During the production of the high-pressure fuel rail, the center distance of the high-pressure fuel rail needs to be tested to improve its accuracy.

[0003] A search revealed a high-pressure oil rail center distance detection device disclosed in announcement number "CN222505251U". The device includes a main scale body and a caliper digital display body. A stationary clamp is fixedly mounted at the end of the main scale body, and a movable clamp is mounted on the caliper digital display body. An adjustment mechanism is provided between the stationary clamp and the main scale body. The adjustment mechanism includes a calibration plate, which is fixedly connected to one end of the main scale body. This detection mechanism allows for position adjustment of the stationary clamp located at the end of the main scale body along the extension direction of the main scale body. This allows for position adjustment after replacing the stationary clamp on the main scale body, enabling the movable clamp and stationary clamp to engage and achieve zeroing of the caliper digital display body. This not only provides flexibility and convenience but also improves the quality of high-pressure oil rail center distance detection using calipers.

[0004] During the use of the aforementioned high-pressure oil rail center distance detection device, we found that there was a gap between the clamping position and the reading position. The distance between the two clamping seats recorded by the caliper digital display body was too large, which affected the accuracy of the high-pressure oil rail detection data. To address this issue, we designed a high-pressure oil rail detection mechanism to solve the above technical problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figure 1-4 The high-pressure oil rail detection mechanism shown includes a fixing bar 1, with scale lines 2 engraved on the front of the fixing bar 1. Two fixing frames 3 are slidably connected to the surface of the fixing bar 1. Connecting bars 6 are fixedly installed on the front of the two fixing frames 3. Clamps 7 are detachably fixedly installed at the ends of the two connecting bars 6. Movable markers 12 are provided on the sides of the two clamps 7.

[0021] Specifically, during the high-pressure oil rail inspection, the markers 12 set on the side walls of the two clamps 7 are moved to contact the scale lines 2 on the surface of the fixed strip 1, which improves the reading accuracy and enables precise detection of the center distance of the high-pressure oil rail, thus improving the accuracy of the inspection data.

[0022] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a high-pressure oil rail detection mechanism. Both ends of the fixing strip 1 are fixed with blocks 5, and the size of the blocks 5 is larger than the size of the ends of the fixing strip 1.

[0023] Specifically, by setting the end block 5 of the fixing strip 1, the fixing frame 3 is prevented from separating from the fixing strip 1 during the movement of the fixing frame 3, thus avoiding affecting the detection of the high-pressure oil rail.

[0024] Both clamps 7 have connecting grooves 13 at their ends. The ends of the two connecting strips 6 are inserted into the connecting grooves 13. Both sides of the connecting grooves 13 have insertion holes 16. The ends of the connecting strips 6 have grooves 14. T-shaped posts 17 are inserted into both sides of the grooves 14. A return spring 15 is fixedly installed between the two T-shaped posts 17. One end of the two T-shaped posts 17 is inserted into the corresponding insertion hole 16.

[0025] Specifically, the end of the connecting strip 6 is inserted into the connecting groove 13, and the T-shaped posts 17 set on both sides of the end of the connecting strip 6 are extended and retracted by the return spring 15, so that the T-shaped posts 17 can be inserted into and separated from the insertion holes 16 opened on both sides of the connecting groove 13, which facilitates the installation and disassembly of the connecting strip 6 and the clamp 7, and facilitates the replacement of the clamp 7 when it is damaged.

[0026] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a high-pressure oil rail detection mechanism. The side walls of the two clamps 7 are provided with T-shaped grooves 10. T-shaped sliders 11 are slidably connected inside the two T-shaped grooves 10. The ends of the two T-shaped sliders 11 are fixedly connected to the ends of the marker rods 12.

[0027] Specifically, the T-shaped slider 11 slides inside the T-shaped groove 10, causing the pointer 12 to move. This allows the end of the pointer 12 to abut against the scale line 2 on the front of the fixing strip 1, making it easier to read the distance between the two pointers 12 and improving the reading accuracy, thereby improving the accuracy of the high-pressure oil rail detection data.

[0028] The top of the T-shaped slide 10 is provided with a through groove 8, and a push block 9 is slidably connected inside the through groove 8. The bottom end of the push block 9 is fixedly connected to the top of the T-shaped slider 11.

[0029] Specifically, the push block 9 provided inside the through groove 8 facilitates the movement of the T-shaped slider 11 and avoids the problem of the T-shaped slider 11 disengaging from the T-shaped groove 10.

[0030] Both fixed frames 3 have locking bolts 4 threadedly connected to their top ends, and the ends of the locking bolts 4 abut against the top ends of the fixed strips 1.

[0031] Specifically, by locking the bolt 4 against the top of the fixing strip 1, the fixing frame 3 is easily fixed. The clamp 7 is fixed by fixing the fixing frame 3, which improves the stability of the clamp 7 during the high-pressure oil rail center distance detection process.

[0032] The working principle of this utility model is as follows: When using this high-pressure oil rail detection mechanism, firstly, one of the clamps 7 is manually brought into contact with the side of the high-pressure oil rail. Then, the other clamp 7 is manually pushed to make it contact the other side of the high-pressure oil rail. Then, the locking bolt 4 is rotated, and the locking bolt 4 abuts against the fixing strip 1, which facilitates the fixing of the fixing frame 3. The clamp 7 is fixed by fixing the fixing frame 3. Then, the push block 9 is manually pushed, which drives the T-shaped slider 11 to move. The movement of the T-shaped slider 11 drives the movement of the scale rod 12, so that the end of the scale rod 12 contacts the scale line 2 on the front of the fixing strip 1. The center distance of the high-pressure oil rail is obtained by reading the scale distance between the two scale rods 12.

[0033] It should be noted that during the sliding process, the T-shaped slider 11 will not slide out of the T-shaped groove 10 because it is fixedly connected to the push block 9. At the same time, the clamp 7 and the connecting strip 6 are connected and installed by the T-shaped post 17 and the insertion hole 16, which facilitates the replacement of the clamp 7 when it is damaged.
