Description

Technical Field

[0001] This utility model relates to the field of manufacturing technology of high-pressure common rail oil pumps for diesel vehicles, specifically to a device for detecting the clearance of the camshaft of a high-pressure pump body and selecting gaskets. Background Technology

[0002] The high-pressure common rail system pressurizes fuel to 1300-2000 bar using a high-pressure pump, achieving good fuel atomization. After pressurization, the fuel enters the common rail, which acts as an energy storage device, storing high-pressure fuel and providing uniform fuel pressure to each cylinder. It offers advantages such as quieter, more powerful, cleaner, and more fuel-efficient diesel engines. However, after manufacturing, the high-pressure common rail fuel pump for diesel vehicles requires a series of inspections before leaving the factory. Current inspection technologies have the following drawbacks: 1. Measurement accuracy needs improvement: Some detection technologies calculate axial clearance by monitoring the displacement of external tooling, and tooling deformation can affect the measurement results. When using a single actuator to apply force in one direction, the results are not accurate enough; while using two actuators, the cumulative error due to the accuracy of the actuators leads to an increase in error. In addition, methods such as manual feeler gauge measurement and manual dial indicator calculation are easily affected by human factors, making it difficult to guarantee accuracy.

[0003] 2. Low testing efficiency: Some testing methods, such as manually pushing the crankshaft back and forth and measuring with a dial indicator, are cumbersome and time-consuming. Other tests are typically only for laboratory use, involving manual tooling and fixtures to fix the workpiece, resulting in complex testing procedures that are unsuitable for online measurement, cannot be integrated into production equipment, and fail to meet the needs of large-scale production.

[0004] 3. High equipment and operational requirements: Some testing equipment has a complex structure, large size, occupies a lot of space, and is costly. When using general-purpose tooling for testing in the laboratory, repeated adjustments to the equipment are required, placing extremely high demands on the skills and experience of the operators.

[0005] 4. Limited applicability: For automotive steering ball pins, since the middle part is spherical, the angle between the ball pin and the housing is easily changed when force is applied, and existing detection devices are difficult to accurately detect its axial clearance.

[0006] 5. Highly susceptible to environmental factors: Visual image-based detection technology is prone to accuracy issues because shaft and hole workpieces are mostly metal, resulting in unstable image edges. Furthermore, occlusion by the shaft or workpiece can lead to missing edge information, further affecting detection accuracy. In addition, environmental factors such as temperature, humidity, and vibration during measurement can also interfere with the results, and current correction and compensation measures are not yet fully developed.

[0026] The working principle of this specific implementation is as follows: Place the oil-sealed iron side cover into the positioning base 104, and place the oiled iron side cover into the positioning base 104. Press the start button 7. The first drive device 102 will rotate the lead screw 101. The rotation of the lead screw 101 will move the positioning base 104 located above the slide plate to directly below the press 106. The press 106 will press down until it contacts the upper surface of the iron side cover. The through-beam switch 107 will operate to check whether there is an O-ring in the press head. If there is, the press 106 will press down. If not, an error message will be displayed. After pressing, the press 106 will return to its original position.

[0027] The first drive unit 102 continues to move the positioning base 104 below the side cover measuring clamping seat 112. The third drive unit 118 moves the first connecting plate 116 downward, causing the probe of the first displacement sensor 115 to descend and contact the zeroing point of the measuring connecting rod 113. The second drive unit 111 moves the second detection slide plate 206 downward, causing the side cover measuring clamping seat 112 to be flush with the surface of the iron side cover. The iron side cover pushes the measuring connecting rod 113 located in the side cover measuring clamping seat 112 upward. The first displacement sensor 115 measures the height of the iron side cover boss by detecting the displacement of the measuring connecting rod 113 and transmits the data to the control module. After the detection is completed, the second drive unit 111 moves the second detection slide plate 206 back to its original position, the third drive unit 118 moves the first connecting plate 116 back to its original position, and the first drive unit 102 moves the positioning base 104 back to its original position. The pressed iron side cover is then removed and placed on the high-pressure pump body.

[0028] Push the high-pressure pump body under the camshaft height measuring module 3, press the start button 7, and the lifting cylinder 205 lifts the high-pressure pump body. The fifth drive device 213 moves the second connecting plate 212 downward, so that the probe of the second displacement sensor 211 contacts the zero point of the pump body measuring rod 209. The fourth drive device 207 moves the second detection slide plate 206 downward, so that the body measuring clamping seat is flush with the body flange surface. The second displacement sensor 211 measures the height from the camshaft head to the flange surface through the displacement of the pump body measuring rod 209 and transmits the data to the control module. After the detection is completed, the fourth drive device 207 moves the second detection slide plate 206 back to its original position, and the fifth drive device 213 moves the second connecting plate 212 back to its original position.

[0029] By controlling the sixth drive device 302, the turntable rotates to the position for selecting the shim. The seventh drive device 309 activates, causing the positioning plate 332 to lock the turntable. The eighth drive device 311 activates, driving the shim extraction claw 310 to extract the adjusting shim 306 at the bottom of the hopper 305. Subsequently, the eighth drive device 311 returns to its original position. The ninth drive device 317 activates, driving the first slide plate 318 to move along the X-axis. The tenth drive device 320 activates, driving the third detection plate to move along the Z-axis. After adjusting the thickness measurement sensor 313 to the appropriate position, the thickness of the adjusting shim 306 is measured, and the measurement result is transmitted to the control module. The tenth drive device 320 drives the third detection plate, and the ninth drive device 317 drives the first slide plate 318 back to its original position. The twelfth drive unit 330 actuates, moving the shim gripper 322 above the shim extraction gripper 310. The eleventh drive unit 329 actuates, moving the fourth slide plate 328 so that the shim gripper 322 reaches the gripping position and grips the adjusting shim 306. The control module issues different commands based on the thickness measurement result of the adjusting shim 306. If the thickness measurement result is qualified, the eleventh drive unit 329 is controlled to rise, causing the shim gripper 322 to return to its original position. The rotating platform 324 is controlled to rotate, causing the twelfth drive unit 330 to rotate 180° counterclockwise. Subsequently, the eleventh drive unit 329 is controlled to lower the shim gripper 322 to the working position, releasing the adjusting shim 306 and placing it onto the high-pressure pump body camshaft. Upon completion, the eleventh drive device 329 actuates, causing the gasket gripper 322 to rise. The rotating platform 324 rotates, causing the gasket gripper 322 to rotate 180° clockwise. The eleventh drive device 329 then returns the gasket gripper 322 to its original position. If the thickness measurement result is unqualified, the twelfth drive device 330 moves the gasket gripper 322 to the top of the storage box 331, releasing the adjusting shim 306. Subsequently, the twelfth drive device 330 and the first drive device 102 actuate sequentially, causing the gasket gripper 322 to return to its original position.
