Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of production and processing of motorcycle metal oil tanks, in particular to a scooter metal oil tank assembly and a sealing test tool. Background Art
[0002] The general production process of motorcycle metal fuel tanks is as follows: cutting - stamping - welding - welding inspection - sealing test - painting - painting inspection - assembly (removing painting accessories and installing fuel tank accessories) - inspection (inspecting assembly quality) - finished product (final assembly). The sealing test is a must-check item for each fuel tank before leaving the factory. The test method usually adopts the "water test method" or "water tank method". Because it needs to be immersed in water, the sealing test process is generally set before painting and cannot be automated. This process has many disadvantages such as high labor consumption and large space occupation. The applicant proposed improvements to it, using the differential pressure air leak detection method to test the sealing of the fuel tank and moving the process to after the fuel tank assembly.
[0003] The assembly of the scooter fuel tank includes the removal of the plugs placed during the tank painting and the installation of fuel tank accessories such as the fuel pump, usually with the assistance of pneumatic tools. The sealing test involves operations such as inflating the fuel tank filling port. When designing the assembly and sealing test fixtures, it is necessary to consider the convenience of operating the fuel tank in these two process sections. In addition, both process sections are set after painting, and how to better avoid damage to the coating is a key consideration. Utility Model Content
[0004] The utility model aims to provide an oil tank tooling which is suitable for assembly and sealing test stations in a new process flow of a motorcycle metal oil tank.
[0005] The purpose of the utility model is achieved through the following technical solutions: a motorcycle metal fuel tank assembly and sealing test tooling, including a bracket and two seat plates, the two seat plates are supported by the bracket below and are symmetrically arranged on the left and right, and a gap with a large middle and small ends is formed between them to form a guard ring supporting configuration. When the fuel tank to be tested is placed on the tooling, its lower part is located in the ring hole and is positioned, and the fuel tank bracket in the middle is supported on the adjacent sides of the two seat plates.
[0006] Preferably, the seat plate is made of PU board.
[0007] Preferably, the specific structure of the bracket is as follows, which includes three parts: a base frame, a top bracket and a column; the base frame is a square steel frame, which is fixed to the assembly workbench or the sealing test bench with screws, and the upper top bracket is fixed to the seat plate with screws, and the screws are located in the reserved countersunk holes of the seat plate. The top bracket and the base frame are supported by four columns and are spaced apart upper and lower.
[0008] During the assembly, sealing test and transfer process, this structure can completely prevent the fuel tank from coming into contact with any metal, thus preventing damage to the fuel tank surface coating.
[0009] Beneficial effects:
[0010] By using the tooling of the utility model, the oil tank is supported on the working seat plate by the oil tank bracket, which is square and stable, and can well avoid the occurrence of damage to the surface coating of the oil tank during assembly, sealing test and transfer. In addition, the use of the tooling of the utility model is not only convenient for disassembling the tooling during the oil tank coating by pneumatic tools during the assembly stage, and installing the oil pump and other oil tank accessories, but also convenient for the oil tank to conduct sealing test.

[0016] like Figure 1-5 As shown, the motorcycle metal fuel tank assembly and the sealing test fixture of this embodiment include a bracket 2 and two seat plates 1. The two seat plates 1 are supported by the bracket 2 at the bottom and are symmetrically arranged on the left and right. A gap with a large middle and small ends is formed between them to form a guard ring supporting configuration. When the fuel tank to be tested is placed on the fixture, its lower part is located in the ring hole and is positioned, and the fuel tank bracket in the middle is supported on the adjacent sides of the two seat plates 1.
[0017] The seat plate 1 of this embodiment is made of a 40 mm thick PU plate.
[0018] The bracket 2 is mainly used to support the two seat plates 1. In this embodiment, the specific structure is as follows: the bracket 2 is divided into three parts, all of which are made of L40 angle steel. The base frame 21 is a square angle steel frame, which is fixed to the assembly workbench or the sealing test bench with hexagonal screws. The upper top bracket 22 is two angle steels, which are fixed to the seat plate 1 with hexagonal screws, and the seat plate 1 has reserved countersunk holes. There are four angle steel columns 23 between the base frame 21 and the upper top bracket 22, and the two ends of the columns 23 are welded to the base frame 21 and the top bracket respectively. During the assembly, sealing test and transfer process, this structure can completely prevent the fuel tank from touching any metal, and prevent damage to the surface coating of the fuel tank.
[0019] The above-mentioned tooling is used to place the oil tank, which is supported on the working seat plate by the oil tank bracket, and is square and stable. During the assembly, sealing test and transfer process, damage to the surface coating of the oil tank can be avoided. In addition, the use of the utility model tooling is not only convenient for disassembling the tooling during the oil tank coating by pneumatic tools during the assembly stage, and installing oil tank accessories such as oil pumps, but also convenient for the oil tank to be tested for sealing.
[0020] The work contents of assembly and sealing tests are different, and the requirements are different. In the utility model, a consistent tooling is adopted, and the tooling seat plate adopts a contoured configuration, and the support is achieved through the oil tank bracket. It is not only square and stable, but also the sitting posture of the oil tank is consistent, which can well meet the requirements of standardized operating procedures.
