Description

Technical Field

[0001] This utility model relates to the field of engine testing technology, and in particular to a distribution conveying device for detecting the protrusion height of fuel injectors. Background Technology

[0002] During the final assembly process in the workshop, the detection of the injector protrusion height is a key quality control step, and its role and reasons are closely related to the engine's performance, reliability, and safety.

[0003] The protrusion height of the fuel injector directly affects its relative position to the combustion chamber. If the height is inappropriate, the fuel injection angle, range, and atomization effect will deviate from the design requirements, leading to incomplete combustion, increased fuel consumption, or excessive emissions.

[0004] If the injector protrudes too high, it may collide with moving parts such as pistons and valves, leading to abnormal engine noise, wear, or even serious malfunctions (such as piston top perforation); if the protrusion is too low, it may affect the mixing effect of fuel spray and intake air.

[0005] When installing fuel injectors, they must fit tightly against the cylinder head or combustion chamber sealing surface. Abnormal protrusion height may lead to poor sealing, causing fuel leaks, airtightness failure, or even difficulty starting the engine or stalling during operation.

[0006] In mass production, a uniform injector protrusion height is fundamental to ensuring consistent engine performance. Testing can reduce individual variations caused by assembly errors, guaranteeing stable key parameters such as power output and emissions for engines of the same model.

[0007] The existing injector protrusion height detection scheme has certain drawbacks. The operation process of the existing injector protrusion height detection scheme is relatively cumbersome. The operator needs to first stand up the cylinder head, add a copper washer to assemble the injector in place, and then use a dial indicator to check the protrusion height of the injector.

[0008] During this process, manual measurement is required by the operator. The operator needs to remove the cylinder seat and further inspect it. After inspection, the cylinder seat is placed back on the conveying equipment, or it can be inspected directly on the conveying equipment. However, the conveying device needs to be paused during inspection, which makes the overall measurement efficiency relatively low.

[0009] In summary, the existing solutions have certain shortcomings and do not meet the requirements of automated mechanical processing. Therefore, we propose a distributed conveying device for detecting the protrusion height of fuel injectors. Utility Model Content

[0010] The main objective of this invention is to provide a distributed conveying device for detecting the protrusion height of fuel injectors. It replaces a single transmission with a three-section conveying assembly, in which each of the three conveying assemblies can operate independently. Therefore, the detection process does not affect the operation of the first and third conveying assemblies, effectively reducing the impact of detection on the cylinder seat conveying, thereby effectively improving efficiency. It has good performance and promising application prospects, and can effectively solve the problems in the background technology.

[0011] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0042] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0043] This application provides a distributed conveying device for detecting the protrusion height of fuel injectors, addressing certain drawbacks of existing fuel injector protrusion height detection schemes. Existing fuel injector protrusion height detection schemes involve cumbersome operation procedures. Operators must first erect the cylinder head, install the fuel injector with a copper washer, and then use a dial indicator to check the protrusion height. This process requires manual measurement by the operator, who must remove the cylinder head and further inspect it before placing it back on the conveying equipment. Alternatively, the measurement can be performed directly on the conveying equipment, but this requires pausing the conveying device, resulting in low overall measurement efficiency.

[0044] Example 1

[0045] like Figure 1-5As shown, a distribution conveying device for detecting the protrusion height of fuel injectors is used to convey the protrusion height of several fuel injectors on the cylinder head 1, both before and after detection. The device includes a main body 2, a first conveying assembly 3, a third conveying assembly 5, and a second conveying assembly 4.

[0046] The first conveying assembly 3 is used to transfer the cylinder seat 1 from the injector installation station to the first end of the injector protrusion height detection station.

[0047] The third conveyor assembly 5 is used to transport the cylinder seat 1 from the end of the injector protrusion height detection station to the subsequent processing station.

[0048] The second conveyor assembly 4 is used to adjust the position of the cylinder seat 1 on the injector protrusion height detection station;

[0049] Among them, conveyor assembly 3, conveyor assembly 4 and conveyor assembly 5 are installed on the main body 2 of the device in sequence.

[0050] The above solution is mainly aimed at addressing the problem that existing technologies use a single complete conveyor belt for transportation, but require a pause during testing, which prevents the preceding and subsequent cylinder seats 1 from operating, resulting in low transportation efficiency.

[0051] Compared to existing manual removal methods, this solution requires no manual assistance, can achieve static positioning, and can be directly limited by a limiting device, reducing the workload of relevant personnel and improving the intelligent detection effect of the equipment.

[0052] In use, the first conveyor assembly 3 transfers the cylinder seat 1 from the injector installation station to the first end of the injector protrusion height detection station. The second conveyor assembly 4 adjusts the position of the cylinder seat 1 on the injector protrusion height detection station and, in conjunction with the limiting device, limits the cylinder seat 1. At this time, the injector protrusion height is detected. After the detection, the second conveyor assembly 4 adjusts the position of the cylinder seat 1 on the injector protrusion height detection station so that the cylinder seat 1 reaches the third conveyor assembly 5. The third conveyor assembly 5 transports the placed cylinder seat 1 from the end of the injector protrusion height detection station to the subsequent processing station.

[0053] This solution provides a distributed conveying device for detecting the protrusion height of fuel injectors. It replaces a single transmission with a three-section conveying assembly, and all three conveying assemblies can operate independently. Therefore, the detection process does not affect the operation of the first conveying assembly 3 and the third conveying assembly 5, effectively reducing the impact of detection on the conveying of the cylinder seat 1, thereby effectively improving efficiency. It has good performance and promising application prospects.

[0054] Example 2

[0055] like Figure 1-5As shown, based on Example 1, this example also describes the following structure:

[0056] Conveying assembly 3, conveying assembly 4 and conveying assembly 5 all use roller conveying assemblies, and limit rails 6 are installed on both sides of conveying assembly 3, conveying assembly 4 and conveying assembly 5 on the main body 2 of the device.

[0057] The above structure is designed to ensure the stable transport of the cylinder seat 1 and prevent the cylinder seat 1 from swaying and becoming scattered during transport.

[0058] In use, conveyor assembly 3, conveyor assembly 4, and conveyor assembly 5 convey the cylinder seat 1, ensuring that the cylinder seat 1 is always positioned between the limit bars 6. The roller conveyor assembly prevents the cylinder seat 1 from contacting the upper surface of the device body 2, reducing wear, and also prevents debris from affecting the stability of the cylinder seat 1, thus facilitating testing and improving the efficiency of subsequent testing.

[0059] The roller conveyor assembly includes a drive unit 7, roller components, and a transmission unit;

[0060] The driving component 7 is installed inside the main body 2 of the device; there are several groups of rollers, and the several groups of rollers are arranged in parallel at equal intervals; there are several groups of transmission components, and the rollers are connected to each other in sequence through transmission components.

[0061] Among them, the driving component 7 drives all the roller components to rotate synchronously through the transmission component.

[0062] The design of the above structure is mainly to ensure that the roller conveyor assembly can deliver materials stably.

[0063] In use, the drive unit 7 drives one set of rollers to rotate, and the rollers drive the other rollers to rotate through the transmission unit, thereby making the roller conveying assembly rotate as a whole, thus achieving stable conveying of the cylinder seat 1, which is relatively convenient to use.

[0064] The roller assembly includes a guide wheel 8 and a drive rod 9.

[0065] There are two sets of guide wheels 8, which are set in grooves on the main body 2 of the device; the transmission rod 9 has two sets of guide wheels 8 symmetrically arranged at the ends of the transmission rod 9.

[0066] The roller assembly is similar to existing common structures, mainly ensuring that the two sets of guide wheels 8 rotate at the same speed through the transmission rod 9, thereby ensuring a stable conveying speed.

[0067] Drive unit 7 includes a motor assembly with a brake structure and transmission components:

[0068] The motor assembly with a brake structure is located inside the main body 2 of the device; the motor assembly is connected to one of the transmission rods 9 through a transmission component.

[0069] The motor assembly with a brake structure can lock, thereby preventing the guide wheel 8 from rotating and improving the limiting effect of the main body 2 of the device during detection.

[0070] In use, the motor assembly with the brake structure drives the transmission rod 9 in one of the roller components to rotate through the transmission component. The transmission rods 9 between adjacent roller components are connected through the transmission component, thus driving all the transmission rods 9 to rotate, thereby achieving stable conveying.

[0071] To improve stability, the transmission rod 9 passes through a bearing inside the main body 2 of the device. The bearing provides support, making the cylinder seat 1 more stable during transportation.

[0072] Both the transmission components and transmission parts include a transmission chain 10 and two sets of transmission teeth 11, with the transmission chain 10 meshing with the transmission teeth 11.

[0073] The transmission structure formed by the transmission chain 10 and the two sets of transmission teeth 11 can ensure that all transmission rods 9 rotate stably and constantly, resulting in more stable and better conveying.

[0074] One set of limit bars 6 has a dust suction channel 12 inside, and a dust collection box 13 is installed on the outside of the limit bars 6. The dust collection equipment inside the dust collection box 13 is connected to the dust suction channel 12. Several sets of dust inlets 14 are equally spaced on the outside of the limit bars 6 facing the motor assembly.

[0075] The above structure is mainly designed to address the issue that existing equipment is prone to accumulating dust and debris, which can affect the normal operation of the device and its lifespan.

[0076] When in use, the vacuuming device inside the vacuum box 13 is activated. The suction generated by the vacuuming device draws the dust on the main body 2 through the dust inlet 14 into the dust suction channel 12, and then moves along the dust suction channel 12 into the vacuum box 13. The dust inside the vacuum box 13 can be cleaned periodically.

[0077] An auxiliary rod 15 is installed at the end of the guide wheel 8 away from the transmission rod 9. A cleaning wheel 16 is fixedly installed on the auxiliary rod 15. When the guide wheel 8 rotates, it drives the auxiliary rod 15 to rotate, so that the cleaning wheel 16 assists the dust in the dust suction channel 12 to move.

[0078] When in use, the guide wheel 8 will rotate, and the rotation of the guide wheel 8 will drive the auxiliary rod 15 to rotate. The rotation of the auxiliary rod 15 will drive the cleaning wheel 16 to rotate, and the cleaning wheel 16 will rotate to sweep away dust and prevent dust from sticking to the dust suction channel 12.

[0079] The bottom surface of the dust suction duct 12 is inclined, and the lower the bottom surface of the dust suction duct 12 is, the easier it is for dust to move. The rotation of the cleaning wheel 16 will cause air to flow, preventing dust from sticking to the bottom surface of the dust suction duct 12 and ensuring the dust removal effect.

[0080] It should be noted that this utility model describes a distribution conveying device for detecting the protrusion height of an injector. In use, the first conveying component 3 transports the cylinder seat 1 from the injector installation station to the first end of the injector protrusion height detection station. The second conveying component 4 adjusts the position of the cylinder seat 1 at the injector protrusion height detection station, and, in conjunction with a limiting device, limits the cylinder seat 1. At this time, the injector protrusion height is detected. After detection, the second conveying component 4 adjusts the position of the cylinder seat 1 at the injector protrusion height detection station so that the cylinder seat 1 reaches the third conveying component 5. The third conveying component 5 then places the cylinder seat 1 from the injector protrusion height detection station... The dust is transported from the end of the station to the subsequent processing station. When conveying components 3, 4, and 5 are in use, the dust collection equipment inside the dust collection box 13 is activated. The suction generated by the dust collection equipment draws the dust on the main body 2 through the dust inlet 14 into the dust suction channel 12, and then moves along the dust suction channel 12 into the dust collection box 13. At the same time, the guide wheel 8 rotates, which drives the auxiliary rod 15 to rotate. The rotation of the auxiliary rod 15 drives the cleaning wheel 16 to rotate. The rotation of the cleaning wheel 16 cleans the dust. The rotation of the cleaning wheel 16 causes the air to flow, preventing the dust from sticking to the bottom surface of the dust suction channel 12 and ensuring the dust removal effect.

[0081] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
