Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, and in particular to a machining fixture for a fuel nozzle. Background Technology

[0002] The fuel nozzle is the terminal part of the fuel dispenser at a gas station, that is, the part that comes into contact with the car's fuel tank. Commonly used types are self-sealing fuel nozzles and composite fuel nozzles. During the manufacturing process of fuel nozzles, machining fixtures are used to limit and position the nozzle.

[0003] Processing fixtures generally have a simple structure, using a flat plate to hold a single material, with a cylinder on the plate to limit the material. However, due to the special structure of the fuel nozzle, there are many bends and arcs at the end wall. The bends of the fuel nozzle often collide with the flat plate, making it difficult to load the fuel nozzle onto the fixture. Even if it is forcibly loaded, there will be many dead angles for the fuel nozzle, which is not conducive to processing after the fuel nozzle is limited. Utility Model Content

[0004] The purpose of this invention is to provide a jig for processing fuel nozzles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fuel nozzle processing fixture includes a support plate. A side seat is fixed to one side of the upper wall of the support plate. A main support block is installed on the side seat near the center of the support plate. An auxiliary support block is installed on the side seat near the center of the support plate and away from the main support block. A slot for engaging the end wall of the fuel nozzle is formed on the upper end wall of the auxiliary support block. A patch for abutting and limiting the end wall of the fuel nozzle is placed on the side seat near the end wall of the main support block. A center seat is fixed to the center of the upper wall of the support plate. A seat side groove is formed on one end wall of the center seat. A top position cylinder is provided on the center end wall near the seat side groove and on the top end wall of the center seat. A side cylinder fixedly connected to the support plate is installed on the side wall of the center seat. A secondary seat is installed on the upper wall of the support plate near the center seat and away from the side seat. A seat recess is formed on the upper wall of the secondary seat. A limiting cylinder is installed on the secondary seat near the center end wall of the seat recess. A pressure plate for limiting the end wall of the fuel nozzle is provided on the upper end wall of the limiting cylinder.

[0007] Preferably, the side seat is fixedly connected to the patch, the main support block and the auxiliary support block, and the main support block and the auxiliary support block are fixedly connected to the support plate.

[0008] Preferably, the top cylinder and the side cylinder work together to press against the end wall of the refueling nozzle and limit the position of the refueling nozzle.

[0009] Preferably, the main support block, auxiliary support block, and patch work together to provide abutment support to the bottom and sidewalls of the fuel nozzle.

[0010] Preferably, the secondary seat is triangular in shape, and a limiting cylinder is fixedly connected to the right wall of the triangular prism of the secondary seat, so that the limiting cylinder is inclined relative to the support plate, and the right wall of the triangular prism of the secondary seat is used to tilt and support the refueling gun.

[0011] Preferably, the limiting cylinder and the pressure plate are driven by each other, and the lower wall of the pressure plate moves down and fits tightly against the upper wall of the fuel nozzle, thereby limiting the fuel nozzle.

[0012] This utility model has at least the following beneficial effects:

[0013] The fixture has two stations. One station suspends the fuel nozzle, allowing the bottom of the bent fuel nozzle to hang in the air and preventing the bent end wall from contacting the fixture support plate, making it easy to place the fuel nozzle. The other station is used to tilt the fuel nozzle, tilting and raising the end wall of the fuel nozzle to fully expose the end of the fuel nozzle for processing. The two stations are used in combination to allow the fuel nozzle to be processed in different states, fully exposing the bent end wall of the fuel nozzle without any blind spots, so as to facilitate thorough and complete processing of the fuel nozzle in the future.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a fuel nozzle processing fixture:

[0022] like Figure 1-4 As shown, a fuel nozzle processing fixture includes a support plate 1. A side seat 2 is fixed to one side of the upper wall of the support plate 1. A main support block 4 is installed on the side seat 2 near the center of the support plate 1. An auxiliary support block 6 is installed on the side seat 2 near the center of the support plate 1 and away from the main support block 4. The main support block 4, the auxiliary support block 6, and the mounting plate 3 cooperate to abut against and support the bottom and side wall of the fuel nozzle. The upper end wall of the auxiliary support block 6 has a slot 7 for engaging the end wall of the fuel nozzle. The side seat 2 is provided with abutment against the main support block 4. The patch 3 on the end wall of the fuel nozzle is fixedly connected to the side seat 2, the main support block 4, and the auxiliary support block 6. The main support block 4 and the auxiliary support block 6 are fixedly connected to the support plate 1. The end wall of the fuel nozzle is respectively engaged by the slot 7, supported by the L-shaped main support block 4, and abutted against the patch 3 for limiting. Then, the top cylinder 10 and the side cylinder 11 are used to press against one side wall of the fuel nozzle to limit and position the fuel nozzle, so that the bottom of the fuel nozzle is suspended and lifted, which is convenient for adapting to fuel nozzles with bent end walls and making it easier to load the fuel nozzle.

[0023] like Figure 1 and Figure 4 As shown, a central seat 8 is fixed at the center of the upper wall of the support plate 1. A seat side groove 9 is provided on one side end wall of the central seat 8. A top position cylinder 10 is provided at the center end wall of the central seat 8 near the seat side groove 9 and at the top end wall of the central seat 8. A side cylinder 11 is installed on the side wall of the central seat 8 and is fixedly connected to the support plate 1. The top position cylinder 10 and the side cylinder 11 work together to press against the end wall of the fuel nozzle and limit the position of the fuel nozzle.

[0024] like Figure 1 and Figure 3As shown, a secondary seat 12 is installed on the upper wall of the support plate 1 near the central seat 8 and away from the side seat 2. A seat recess 13 is opened on the upper wall of the secondary seat 12. A limiting cylinder 14 is installed on the central end wall of the secondary seat 12 near the seat recess 13. A pressure plate 5 for limiting the end wall of the fuel nozzle is provided on the upper end wall of the limiting cylinder 14. The secondary seat 12 is triangular in shape. The limiting cylinder 14 is fixedly connected to the right wall of the triangular prism of the secondary seat 12, so that the limiting cylinder 14 is inclined relative to the support plate 1. The right wall of the triangular prism of the secondary seat 12 is used to tilt and support the fuel nozzle. The limiting cylinder 14 and the pressure plate 5 are driven by each other. The lower wall of the pressure plate 5 moves down and is close to the upper end wall of the fuel nozzle, so that the fuel nozzle is limited. The upper right wall of the secondary seat 12 is inclined, which is used to tilt the fuel nozzle. When the fuel nozzle is limited, it is in an inclined state. Therefore, during the processing, the end of the fuel nozzle away from the secondary seat 12 can be exposed for subsequent processing.

[0025] Working principle: The support plate 1, side seat 2, patch 3, main support block 4, auxiliary support block 6, slot 7, center seat 8, side seat groove 9, top position cylinder 10, and side cylinder 11 cooperate to form a processing station, used for horizontal placement, limiting, and supporting the oil gun. During limiting:

[0026] One end of the bottom wall of the fuel nozzle is supported by the main support block 4, and the other end is supported by the slot 7 at the auxiliary support block 6. The side wall is abutted and limited by the patch 3. Then, the two top cylinders 10 and the side cylinder 11 at the center seat 8 are operated to abut and limit the three nodes of the side wall of the fuel nozzle, so that the processing gun is in a stable state, which is convenient for subsequent processing. The main support block 4 and the auxiliary support block 6 lift the fuel nozzle, so that the bottom of the fuel nozzle is suspended in the air, which is convenient for the placement of the bent fuel nozzle.

[0027] The secondary seat 12, seat notch 13, pressure plate 5, and limit cylinder 14 work together to form another processing station, used to tilt the fuel nozzle and raise the end of the fuel nozzle. During the limit position:

[0028] Place the end wall of the fuel nozzle on the inclined right wall of the secondary seat 12. Then, the limiting cylinder 14 operates, and the pressing plate 5 moves down and close to the secondary seat 12 to press the top wall of the fuel nozzle, so that the fuel nozzle is tilted and firmly positioned on the secondary seat 12, so that the end of the fuel nozzle that is tilted can be fully exposed, so that the bent end wall of the fuel nozzle can be easily processed later.

[0029] The fixture has two stations working together to process the fuel nozzle in different states, so that the bent end wall of the fuel nozzle is fully exposed without any blind spots, so as to facilitate the subsequent full and thorough processing of the fuel nozzle.

[0030] 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.
