Abstract
Description
Technical Field
[0001] This utility model specifically relates to a tooling for measuring the size of a gearbox fuel injector. Background Technology
[0002] The fuel injector itself is a normally closed valve (a normally closed valve means that the valve is always closed when there is no input control signal; while a normally open valve is always open when there is no input control signal), and the opening and closing of the valve is controlled by the up and down movement of a valve needle.
[0003] Currently, fuel injectors need to be packaged after production. However, since the specific size of the fuel injectors cannot be determined, they cannot be installed in a suitable packaging box in a timely manner. Therefore, a gearbox fuel injector size measuring fixture is proposed. Utility Model Content
[0004] The purpose of this utility model is to provide a tooling for measuring the size of a gearbox fuel injector, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a gearbox injector size measuring fixture, comprising a worktable, a distance adjustment component, a height adjustment component, a positioning component, and a measuring component. The height adjustment component is mounted on the worktable surface via the distance adjustment component. The height adjustment component includes a lifting platform. The measuring component is mounted on the lifting platform. The injector to be measured is positioned within the measuring range of the measuring component via the positioning component.
[0006] Preferably, the distance adjustment component includes a guide rail disposed on the surface of the worktable, a first slide block that slides along the length of the guide rail, and a limit wrench disposed on the outer side of the first slide block.
[0007] Preferably, the height adjustment assembly further includes a base disposed on the upper surface of the slide, a scale column is mounted on the base, and the lifting platform is slidably disposed on the scale column by bolts.
[0008] Preferably, the measuring component includes a transverse measuring tube disposed on a lifting platform, a second slide is disposed on the transverse measuring tube, an mounting block is mounted on the second slide, and an oil dripping tube is inserted into the mounting block.
[0009] Preferably, the second slide is provided with a fixing plate on the side facing the oil dripping cylinder. The surface of the fixing plate is provided with a through hole for inserting the oil dripping cylinder, and a fixing ring is provided on the outside of the fixing plate to abut against the oil spray nozzle.
[0010] Preferably, the positioning component includes a support column disposed on the worktable, a fixed seat mounted on the top of the support column, and a limiting insertion hole for inserting a fuel injector is centrally opened on the surface of the fixed seat.
[0011] Preferably, the surface of the fixing base is provided with four limiting rings at equal intervals around the limiting insertion hole.
[0012] The technical effects and advantages of this utility model are as follows: This gearbox fuel injector size measuring fixture inserts the fuel injector to be measured into the limiting socket. By adjusting the axial feed of the limiting bolt, the position of the limiting ring is changed, so that the limiting ring positions and fixes the fuel injector. Then, the first slide block is moved so that the first slide groove slides towards the fuel injector. The bolt is turned, the lifting platform is slid, and the position of the second slide block on the horizontal measuring tube is adjusted so that the dripping tube is located vertically above the fuel injector. As the lifting platform descends, the fixing ring is engaged with the fuel injector, so that the oil in the dripping tube can drip into the fuel injector. On the one hand, the height of the fuel injector is measured by the position of the lifting platform on the scale column. On the other hand, the oil dripping from the dripping tube enters the fuel injector to measure whether there is a blockage. The overall structure is simple and easy to use, which improves the convenience of measurement and facilitates the subsequent packaging and use of the fuel injector. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] To measure the height of the fuel injector, refer to... Figure 1 , Figure 2 and Figure 3 As shown, the system includes a worktable 1, a distance adjustment component, a height adjustment component, a positioning component, and a measuring component. The height adjustment component is mounted on the surface of the worktable 1 via the distance adjustment component. The height adjustment component includes a lifting platform 2. The measuring component is mounted on the lifting platform 2. The fuel injector to be measured is positioned within the measuring range of the measuring component via the positioning component. The fuel injector to be measured is inserted into the limiting hole 16. By adjusting the axial feed of the limiting bolt, the position of the limiting ring 17 is changed, so that the limiting ring 17 positions and fixes the fuel injector. Subsequently, the first sliding... The first slide groove is slid towards the fuel injector by seat 4. The bolt is turned to slide the lifting platform 2 and adjust the position of the second slide seat 9 on the horizontal measuring tube 8 so that the drip tube is located vertically above the fuel injector. As the lifting platform 2 descends, the fixing ring 13 is engaged with the fuel injector, allowing the oil in the drip tube to drip into the fuel injector. On the one hand, the height of the fuel injector is measured by the position of the lifting platform 2 on the scale column 7. On the other hand, the oil dripping from the drip tube enters the fuel injector to measure whether there is a blockage. The overall structure is simple and easy to use, improving the convenience of measurement.
[0022] To facilitate the measurement of the internal permeability of the fuel injector, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the distance adjustment assembly includes a guide rail 3 disposed on the surface of the worktable 1. A first slide block 4, which slides along the length of the guide rail 3, is disposed on the guide rail 3. A limit wrench 5 is disposed on the outer side of the slide block. When the first slide block 4 slides to the desired position along the length of the guide rail 3, the limit wrench 5 can be rotated to fix the first slide block 4 and prevent it from sliding. The height adjustment assembly also includes a base 6 disposed on the upper surface of the slide block. A scale post 7 is mounted on the base 6. The lifting platform 2 is slidably disposed on the scale post 7 by bolts. By adjusting the tightness of the bolts, the lifting platform 2 can slide on the scale post 7 to achieve lifting. The measuring assembly includes a horizontal measuring tube 8 mounted on a lifting platform 2. A second slide 9 is mounted on the horizontal measuring tube 8, and a mounting block 10 is installed on the second slide 9. An oil dripping cylinder 11 is inserted into the mounting block 10. By sliding the second slide 9 on the horizontal measuring tube 8, the oil dripping cylinder 11 can be moved vertically above the nozzle, allowing oil in the oil dripping cylinder 11 to drip into the nozzle later. A fixing plate 12 is provided on the side of the second slide 9 facing the oil dripping cylinder 11. The surface of the fixing plate 12 has a through hole for inserting the oil dripping cylinder 11, and a fixing ring 13 is provided on the outer side of the fixing plate 12 to abut against the nozzle. As the lifting platform 2 descends, the fixing ring 13 abuts against the top of the nozzle, aligning the oil outlet of the oil dripping cylinder 11 with the oil outlet of the nozzle. Over time, if oil appears at the bottom of the nozzle, it ensures that there is no blockage inside the nozzle, thus achieving measurement of internal permeability. The positioning assembly includes a support column 14 mounted on the workbench 1. A fixing seat 15 is mounted on the top of the support column 14. A limiting insertion hole 16 for inserting a fuel injector is centrally located on the surface of the fixing seat 15. Several drainage holes (not shown in the figure) are provided at the bottom of the limiting insertion hole 16 to allow oil passing through the fuel injector to flow out. A collection device for receiving oil is provided on the lower surface of the workbench 1 for subsequent reuse. Four limiting rings 17 are equidistantly arranged on the surface of the fixing seat 15 around the limiting insertion hole 16. The four limiting rings 17 form a positioning area for the fuel injector. Each limiting ring 17 has a positioning bolt on its back. By rotating the positioning bolt, the position of the limiting ring 17 is changed to adjust the size of the limiting area. The size of the limiting insertion hole 16 is suitable for inserting various types of fuel injectors commonly found in the market. By adjusting the limiting rings 17, the fuel injector inside the limiting insertion hole 16 can be fixed.
[0023] In use, first insert the fuel injector to be measured into the limiting socket 16. By adjusting the axial feed of the limiting bolt, change the position of the limiting ring 17 so that the limiting ring 17 positions and fixes the fuel injector. Then, move the first slide block 4 so that the first slide groove slides toward the fuel injector. Tighten the bolt, slide the lifting platform 2 and adjust the position of the second slide block 9 on the horizontal measuring tube 8 so that the drip tube is located vertically above the fuel injector. As the lifting platform 2 descends, the fixing ring 13 is engaged with the fuel injector so that the oil in the drip tube can drip into the fuel injector. On the one hand, the height of the fuel injector is measured by the position of the lifting platform 2 on the scale column 7. On the other hand, the oil dripping from the drip tube enters the fuel injector to measure whether there is a blockage.
[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
