Abstract
Description
Technical Field
[0001] This utility model relates to the field of fuel injector detection technology, and in particular to a lateral movement structure for protruding fuel injector height. Background Technology
[0002] During actual installation, fuel injectors often experience issues where the fuel inlet position is higher or lower than the design value due to differences in the compression of the fuel injector adjusting shim. Since the position of the fuel rod hole on the side of the cylinder head is fixed, the vertical deviation of the fuel inlet position prevents a good sealing surface from being formed between the fuel inlet and the fuel rod. This can easily lead to fuel leakage in high-pressure and vibration environments during testing, and the leakage is not easily detected.
[0003] Currently, a Chinese patent application with patent number "CN202122145912.6" discloses an auxiliary device for detecting the protrusion height of an injector. This device includes an injector body and a base. A height-adjustable connecting column is mounted on the base, and a mounting plate is fixed to the connecting column. A height detection device is mounted on the mounting plate. A limit plate is slidably mounted on the side of the mounting plate, and a protective sleeve is connected to the limit plate. The protective sleeve is fitted onto the injector body and has an inner cavity containing a moisture-proof component. The protective sleeve has multiple vent holes that communicate with the inner cavity. While this device can detect the protrusion height of the injector, it requires the cylinder to be stationary during detection, making it unsuitable for assembly line production testing.
[0004] However, during the implementation of the above technical solution, at least the following technical problems were discovered:
[0005] Unsuitable for assembly line production and prone to detection misalignment: Existing injector height detection devices primarily rely on measuring devices (such as rangefinders, micrometers, etc.) fitting against the outer wall of the injector. The traditional method involves first stopping the cylinder head's movement, then using a lateral movement device to move the detection device above the cylinder head, aligning it vertically with the injectors on the cylinder head. After detection, the lateral movement device moves the detection device to the next injector location, and so on, from one side of the cylinder head to the other. Moving to one side, the injectors on the cylinder head are inspected one by one. This process requires not only the cylinder head to stop moving, but also the lateral movement device to move the inspection device sequentially over each injector. This requires a lot of time and effort. Secondly, since the entire inspection process mainly relies on program control, that is, the program controls the movement distance of the inspection device each time, misalignment at the starting position or error in the inspection program will cause the inspection position to shift, affecting the safety and stability of subsequent inspections. To address this, we propose a lateral movement structure for injector protrusion height. Utility Model Content

[0029] Specifically, when the cylinder head is in contact with the rubber gasket, the connecting wheel is in contact with the outer wall of the cylinder head.
[0030] (III) Beneficial Effects
[0031] 1. By employing a semi-circular bearing ring as the support structure for the telescopic rod, and connecting a rangefinder to the end of the telescopic rod, the rangefinder can be moved by rotation, thus coordinating with the movement of the cylinder head. This allows for the detection of the injectors on the cylinder head during its movement, effectively solving the technical problems of existing injector height detection devices being unable to adapt to assembly line production. This enables non-stop detection, allowing for the detection of injectors on the cylinder head during its movement, thereby improving detection efficiency in conjunction with the production line operation. Secondly, by installing connecting wheels on the cylinder head's movement path and connecting them to the bearing ring via a gear set, the power of the cylinder head's transport is used as the rotational torque of the bearing ring. This not only provides power for the bearing's rotation but also allows for synchronous movement with the cylinder head, ensuring that each rangefinder accurately corresponds to the injectors on the cylinder head, thus improving detection accuracy.
[0032] 2. By connecting a stop bar to one end of the bearing ring and positioning it on the movement path of the cylinder head, the edge position of the cylinder head can be determined during the cylinder head's movement. This facilitates the alignment of the telescopic rod with the injector and, in conjunction with the connecting ring, ensures that the bearing ring moves accurately and synchronously with the cylinder head. Therefore, this effectively solves the technical problem of misalignment that easily occurs in existing injector height detection devices, thereby achieving accurate positioning between the rangefinder and the injector. This allows for the detection of the injectors on the cylinder head during its movement.
[0033] 3. By setting a protrusion with a conductive strip on the bracket and positioning it on the path of the docking seat on the bearing ring, when the docking seat moves to the position corresponding to the protrusion, the electrode pin on the docking seat will engage with the conductive strip on the protrusion. Since the conductive strip is connected to an external computer via a wire, and the electrode pin is electrically connected to the telescopic rod and the rangefinder, it can not only supply power to the telescopic rod and the rangefinder, but also upload the results detected by the rangefinder to the computer, thereby solving the problem of complicated wiring and eliminating the need to connect each powered device to the computer via a wire.

[0054] This application provides a lateral movement structure for injector protrusion height, effectively solving the technical problem that existing injector height detection devices cannot adapt to assembly line production and are prone to detection misalignment. In existing injector height detection devices, a semi-circular bearing ring is used as the support structure for the telescopic rod, and a rangefinder is connected to the end of the telescopic rod. The rangefinder can be moved by rotation, thus coordinating with the movement of the cylinder head to detect the injectors during cylinder head movement. This achieves non-stop detection, improving detection efficiency by coordinating with production line operations. Secondly, a connecting wheel is installed on the cylinder head's movement path and connected to the bearing ring via a gear set. The power of the cylinder head during transport is used as the rotational torque of the bearing ring, providing power for its rotation and allowing synchronous movement with the cylinder head. This ensures that each rangefinder accurately corresponds to the injector on the cylinder head, improving detection accuracy.
[0055] Example 1
[0056] The technical solution in this application embodiment effectively solves the technical problem that existing injector height detection devices cannot adapt to assembly line production and are prone to detection misalignment during use. The overall approach is as follows:
[0057] To address the problems existing in the prior art, this utility model provides a lateral moving structure for the protrusion height of fuel injectors, installed on a conveyor belt 1, for detecting cylinder heads 2 on the conveyor belt 1. This lateral moving structure mainly consists of three parts: first, a detection component (which can be an instrument with distance measuring function, such as a dial indicator) for detecting the fuel injectors 7 on the cylinder head 2; second, a gear set that uses the force of the cylinder head 2 during transportation as the rotational torque of the detection component; and third, a power supply unit for providing power to the detection component. The detection component is ring-shaped, and the distance measuring instruments 67 on it are arranged in a circular array. Figure 5 As shown, the position of the rangefinder 67 can be adjusted by rotation, thereby sequentially detecting the injectors 7 on the cylinder head 2 during its movement. Furthermore, a gear set serves as the power source for the detection assembly, transmitting the thrust generated by the cylinder head 2's movement to the detection assembly. This causes the detection assembly to rotate, ensuring that each rangefinder 67 corresponds one-to-one with the injectors 7 on the cylinder head 2. This achieves continuous detection without stopping the conveyor belt 1, thus enabling rapid detection. Specific details are as follows:
[0058] Detection components, such as Figure 5As shown, the detection component mainly uses a C-shaped support ring 62 as the support structure for the rangefinder 67. A cylindrical central cylinder 61 is located at the center of the ring, and the central cylinder 61 is connected to the inner wall of the support ring 62 via a connecting rod, forming a structure as shown in the diagram. Figure 5 The shape shown also facilitates alignment with the injector 7 on the cylinder head 2 during rotation. To ensure stable contact between the rangefinder 67 and the injector 7, and to accommodate multiple injectors 7 in different positions, multiple telescopic rods 64 are installed on the outside of the support ring 62. The number of telescopic rods 64 corresponds one-to-one with the injector 7. The rangefinder 67 is installed at the end of the telescopic rod 64. When the end of the telescopic rod 64 aligns vertically with the injector 7, the telescopic rod 64 is controlled to move the rangefinder 67 toward the injector 7. Then, based on the value detected by the rangefinder 67 and the position of the edge of the support ring 62, the protrusion height of the injector 7 is determined.
[0059] In order to utilize the force generated by the movement of the cylinder head 2, a gear set (i.e., a linkage assembly) is installed on the edge of the conveyor belt 1. This primarily uses two meshing bevel gears as the connecting structure, with one bevel gear serving as the linkage gear 53. This gear is positioned parallel to the top of the conveyor belt 1 and located near the path of the cylinder head 2's movement. Thus, when the cylinder head 2 travels along the conveyor belt 1, it will contact the edge of the linkage gear 53. Figure 1 As shown; to prevent a hard collision between the cylinder head 2 and the connecting gear 53, a disc-shaped connecting wheel 51 is provided at the bottom of the connecting gear 53, and the outer diameter of the connecting wheel 51 needs to be larger than the outer diameter of the connecting gear 53, such as... Figure 1 , Figure 2 as well as Figure 8 As shown, the cylinder head 2 will contact the connecting wheel 51 immediately. Simultaneously, a rubber ring with anti-slip threads is fitted onto the outer edge of the connecting wheel 51. Thus, as the cylinder head 2 moves from the conveyor belt 1, the outer wall of the cylinder head 2 will contact the rubber ring on the connecting wheel 51, thereby reducing impact. Figure 1 and Figure 2As shown, the power is transmitted to the linkage gear 53. In order to transmit the torque to the bearing ring 62, the bearing ring 62 is connected to another bevel gear through a rod-shaped connector 34. The bevel gear serves as the driven gear 54, and the driven gear 54 meshes with the teeth of the linkage gear 53. Therefore, when the linkage gear 53 rotates, the torque can be transmitted to the connector 34 through the driven gear 54, and then transmitted to the bearing ring 62 on it by the connector 34, thereby providing power to the bearing ring 62. At the same time, the movement of the cylinder head 2 can synchronously drive the bearing ring 62 to rotate, which in turn drives the rangefinder 67 to rotate. When the end of the telescopic rod 64 is aligned with the injector 7, the telescopic rod 64 can be controlled to move the rangefinder 67 in the direction of the injector 7 until the rangefinder 67 is in contact with the surface of the injector 7.
[0060] To support the detection and linkage components, a mounting frame 3 is installed on the outer wall of the conveyor belt 1. The detection and linkage components are positioned at corresponding locations on the mounting frame 3, thereby maintaining their stability. Figure 3 and Figure 4 As shown, the mounting frame 3 is divided into two parts. One part is a horizontally arranged support plate 31. Support bars 33, in an "L" shape, are installed at the bottom and near the edge of the support plate 31. One end of the support bar 33 is connected to the support plate 31 by bolts, and the other end is connected to the outer wall of the conveyor belt 1 by bolts, thus installing the support plate 31 onto one side of the conveyor belt 1. The other part is a vertical plate 32, which is vertically arranged and perpendicular to the support plate 31. The vertical plate 32 is installed on top of the support plate 31 and near the conveyor belt 1. Figure 1 and Figure 3 As shown, the upright plate 32 is connected to the support plate 31 by a column for fixed protection.
[0061] The installation method is as follows:
[0062] The connecting wheel 51 is installed on the support plate 31 and connected to the positioning post 55 on the top of the support plate 31. A snap-fit post 52 is provided at the center of the connecting wheel 51, and a through hole is provided at the center of the snap-fit post 52. When the connecting wheel 51 is sleeved with the positioning post 55, the positioning post 55 is inserted into the through hole, thereby positioning the connecting wheel 51. After installation, the outer edge of the connecting wheel 51 extends above the conveyor belt 1. Then, the connecting gear 53 is installed on the snap-fit post 52. Since the center of the connecting gear 53 and the outer wall of the snap-fit post 52 are provided with snap teeth, when the connecting gear 53 is sleeved on the snap-fit post 52, the snap teeth at the center of the connecting gear 53 and the snap teeth on the outer wall of the snap-fit post 52 mesh with each other, thereby connecting the connecting gear 53 with the connecting wheel 51. Thus, when the connecting wheel 51 rotates, it can drive the connecting gear 53 to rotate synchronously.
[0063] The connector 34 is inserted into the vertical plate 32 and connected to the vertical plate 32 via bearings. The two ends of the connector 34 are located on opposite sides of the vertical plate 32 and are respectively connected to the driven gear 54 and the bearing ring 62. Figure 3 and Figure 4 As shown, when the driven gear 54 rotates, the bearing ring 62 can rotate synchronously, thereby transmitting power from the cylinder head 2 to the bearing ring 62.
[0064] The connector 34 mainly consists of a cylindrical central column 341 and connecting columns mounted on the central column 341. The connecting columns are divided into a front connecting column 342 and a rear connecting column 344. The front connecting column 342 is located on the side of the vertical plate 32 facing the conveyor belt 1, and the rear connecting column 344 is located on the other side of the vertical plate 32. During installation, the driven gear 54 is connected to the rear connecting column 344 on the central column 341, while the bearing ring 62 is connected to the front connecting column 342 and is located at the rear end of the front connecting column 342. A retaining ring 343 is provided to limit the movement distance of the bearing ring 62. The center of the driven gear 54, the center of the central cylinder 61, the outer wall of the front connecting column 344, and the outer wall of the rear connecting column 342 are all provided with locking teeth. When the driven gear 54 is connected to the front connecting column 344 (and the central cylinder 61 is connected to the rear connecting column 342), the locking teeth on them mesh with each other. Therefore, when the central column 341 rotates, it can simultaneously drive the driven gear 54 and the bearing ring 62 to rotate synchronously.
[0065] To enable resetting, a torsion spring 56 is connected to the outside of the positioning post 55 and to the connecting wheel 51. During the rotation of the connecting wheel 51, i.e., when the connecting wheel 51 rotates with the cylinder head 2, the torsion spring 56 between the positioning post 55 and the connecting wheel 51 begins to store force. This allows the torsion spring 56 to drive the bearing ring 62 to rotate in the opposite direction after the cylinder head 2 has moved, thus completing the resetting process. To prevent the bearing ring 62 from over-resetting, a limiting pin 35 is provided on the side of the upright plate 32 facing the bearing ring 62. The limiting pin 35 is positioned on the movement path of the bearing ring 62, thereby limiting the position of the bearing ring 62 when it rotates in the opposite direction. Figure 3 As shown, this ensures the repeatability of the device.
[0066] A stop bar 65 is provided near the end of the bearing ring 62. This ensures that the stop bar 65 remains vertical when the bearing ring 62 is in contact with the limiting pin 35. Figure 3 As shown, a rubber pad 66 is also provided at the end of the baffle 65 to reduce the collision force between the baffle 65 and the cylinder head 2. At the same time, when the cylinder head 2 and the rubber pad 66 are in contact, the connecting wheel 51 is in contact with the outer wall of the cylinder head 2, thereby ensuring the starting position of the rotation of the bearing ring 62.
[0067] In the specific implementation process, the first step, such as Figure 1 As shown, the cylinder head 2 to be tested moves under the drive of the conveyor belt 1, and the position of the bearing ring 62 moves. During the movement, when the cylinder head 2 contacts the stop strip 65 at the end of the bearing ring 62, the connecting wheel 51 on the support plate 31 fits against the outer wall of the cylinder head 2.
[0068] The second step, as Figure 2 As shown, as the cylinder head 2 moves continuously, the connecting wheel 51 rotates under the drive of the cylinder head 2. Since the connecting gear 53 on the connecting wheel 51 meshes with the driven gear 54 at one end of the connecting member 34, and the other end of the connecting member 34 is connected to the central cylinder 61 at the center of the bearing ring 62, the connecting wheel 51 can simultaneously drive the bearing ring 62 to rotate when it rotates with the cylinder head 2. The telescopic rod 64 is driven by the bearing ring 62 to correspond to the injector 7 on the cylinder head 2. When the rangefinder 67 at the end of the telescopic rod 64 corresponds vertically with the injector 7, the telescopic rod 64 is extended to push the rangefinder 67 to the position of the injector 7, thereby detecting the height of the injector 7.
[0069] Third, after the test is completed, control the telescopic rod 64 to retract, and as the cylinder head 2 continues to move, drive the bearing ring 62 to continue to rotate, until the end of the next telescopic rod 64 corresponds vertically with the next injector 7, and repeat the above test process until all injectors 7 are tested.
[0070] Fourthly, during the movement of the connecting wheel 51, the torsion spring 56 between the connecting wheel 51 and the positioning pin 55 continuously stores force. After the cylinder head 2 completes its movement from the connecting wheel 51, the connecting gear 53 rotates in the opposite direction under the force of the torsion spring 56, simultaneously driving the bearing ring 62 to rotate in the opposite direction, thereby resetting the bearing ring 62. During the reverse rotation of the bearing ring 62, it engages with the limiting pin 35 on the vertical plate 32. At this time, the bearing ring 62 engages with the limiting pin 35, and the stop bar 65 remains vertically positioned. Figure 3 As shown, this completes the reset process for future use.
[0071] Example 2
[0072] Based on Example 1, this application provides a structure that can adjust the position of the telescopic rod 64 as needed. The overall concept is as follows:
[0073] In order to drive the telescopic rod 64 to slide on the bearing ring 62, a plurality of docking seats 63 are sleeved on the edge of the bearing ring 62, and the number of the docking seats 63 is the same as the number of the fuel injectors 7. The docking seat 63 mainly includes a sliding block 631. The sliding block 631 is in a "C" shape, and a connecting pin 632 is arranged in the opening of the sliding block 631. The connecting pin 632 is correspondingly inserted into the sliding groove on the edge of the bearing ring 62. In this way, when the sliding block 631 slides, the connecting pin 632 on the sliding block 631 slides along the sliding groove. After the sliding block 631 moves in place, rotate the knob 633 outside the sliding block 631, and squeeze the bearing ring 62 through the knob 633, so as to connect the sliding block 631 with the bearing ring 62, as Figure 9 and Figure 10 shown. Thus, the adjustment of the sliding block 631 is completed. In this way, the telescopic rod 64 can be installed on the sliding block 631, so that the telescopic rod 64 also has a sliding function; similarly, the position and number of the telescopic rod 64 can be freely adjusted according to needs, improving the applicability of the device.
[0074] Embodiment 3
[0075] Based on Embodiment 2, the embodiment of the present application provides a structure capable of supplying power to the telescopic rod 64, thereby simplifying the complicated circuit. The general idea is as follows:
[0076] A "V"-shaped positioning frame 41 is installed on the edge of the conveyor belt 1, and a sleeve 45 is arranged at the bending part of the positioning frame 41. In this way, the sleeve 45 is installed on the connecting member 34 on the vertical plate 32, as Figure 3 and Figure 4 shown. A docking strip 42 is arranged at the bending part of the positioning frame 41. The convex block 43 at the end of the docking strip 42 corresponds to the edge of the bearing ring 62. Secondly, the conductive strip 44 on the convex block 43 is connected to the power supply on the conveyor belt 1 through a wire and is connected to the computer on the conveyor belt 1. It can not only supply power to the telescopic rod 64, but also control the elongation and shortening of the telescopic rod 64 through the computer.
[0077] In order to transmit electricity to the telescopic rod 64, an electrode pin 634 is provided on the sliding block 631 and connected to the telescopic rod 64 and the rangefinder 67 via a wire. This allows the sliding block 631 with the electrode pin 634 to move during the rotation of the bearing ring 62. Since the protrusion 43 at the end of the mating strip 42 corresponds to the edge of the bearing ring 62, the sliding block 631 on the edge of the bearing ring 62 corresponds to the protrusion 43 during the rotation of the bearing ring 62. Furthermore, during the rotation of the bearing ring 62, when the sliding block 631 at the end of the telescopic rod 64 moves to the position corresponding to the protrusion 43... When the position is correct, the conductive strip 44 on the protrusion 43 will be in contact with the electrode pin 634 on the sliding block 631. At this time, the current can enter the conductive strip 44 through the wire, and then enter the electrode pin 634 that is in contact with it through the conductive strip 44. Finally, the current is transmitted to the telescopic rod 64 and the rangefinder 67 through the wire (wire 635) on the electrode pin 634, thereby powering the telescopic rod 64 and the rangefinder 67, and facilitating computer control. As the bearing ring 62 rotates, when the sliding block 631 on the bearing ring 62 is misaligned with the protrusion 43, the power supply stops to the telescopic rod 64 and the rangefinder 67.
[0078] In the specific implementation process, the bearing ring 62 rotates under the drive of the gear set. When the sliding block 631 on the bearing ring 62 corresponds to the protrusion 43 on the bracket 4, the conductive strip 44 on the protrusion 43 will be in contact with the electrode pin 634 on the sliding block 631. At this time, the current can enter the conductive strip 44 through the wire, and then enter the electrode pin 634 that is in contact with it through the conductive strip 44. Finally, the current is transmitted to the telescopic rod 64 and the rangefinder 67 through the wire on the electrode pin 634, thereby supplying power to the telescopic rod 64 and the rangefinder 67. The system is electrically powered and conveniently controlled by a computer. After the test is completed, the telescopic rod 64 is controlled to retract the rangefinder 67, thus completing the test. As the bearing ring 62 rotates, when the sliding block 631 on the bearing ring 62 is misaligned with the protrusion 43, the power supply stops supplying power to the telescopic rod 64 and the rangefinder 67. Similarly, power is supplied to the next telescopic rod 64, and so on, to complete the power supply and testing of each telescopic rod 64 in sequence. This avoids the need for each telescopic rod 64 and rangefinder 67 to be installed with an independent wire, thereby reducing the number of wires.
[0079] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
