Description

Technical Field

[0001] This utility model relates to the field of fuel tank cover manufacturing technology, and in particular to a fuel tank cover welding positioning fixture. Background Technology

[0002] After the fuel tank cap is manufactured, the oil filler ring needs to be welded to the fuel filler hole of the fuel tank cap. When welding the fuel tank cap, a welding positioning fixture is required to position the fuel tank cap to prevent it from shifting. The existing fuel tank cap welding positioning fixture can only position the fuel tank cap and cannot position the oil filler ring. The method of manually positioning the oil filler ring not only has a certain risk factor, but also easily causes the welding position of the oil filler ring to shift, affecting the welding efficiency.

[0003] The prior art patent application with authorization publication number CN220073717U discloses a welding positioning fixture for a fuel tank cap, including a processing table, a first positioning mechanism, and a second positioning mechanism. The first positioning mechanism is located above the processing table and includes four positioning plates and four pushing components. The second positioning mechanism is located on one side above the processing table and includes a lifting component, a rotating component, four moving components, and four clamping plates. By setting the second positioning mechanism, the fuel filler ring can be positioned, so that the fuel filler ring can be more accurately and firmly fixed on the fuel filler hole of the fuel tank cap, and it is not easy for the position to shift. This facilitates the subsequent welding of the fuel tank cap, which helps to improve the welding accuracy and welding efficiency. Compared with the manual positioning of the fuel filler ring, it greatly improves safety and meets the usage requirements.

[0004] However, in the aforementioned prior art, the fuel tank cap is placed directly on the worktable, and the bottom is prone to wear during the clamping process, which affects the integrity of the fuel tank cap and increases unnecessary cost expenditures. Utility Model Content

[0005] The purpose of this utility model is to provide a welding and positioning fixture for fuel tank caps, which aims to solve the problem that in the prior art, when the fuel tank cap is placed directly on the worktable, the bottom is prone to wear during the clamping process, affecting the integrity of the fuel tank cap and increasing unnecessary costs.

[0006] To achieve the above objectives, this utility model provides a welding positioning fixture for a fuel tank cap, comprising a worktable and a support connection unit. The support connection unit includes a base plate, a cylinder, four fixing rods, four arc-shaped seats, four springs, four rubber pads, an arc-shaped ring, and a pressing assembly. The support connection unit is connected to the worktable. The base plate is positioned above the worktable. The cylinder is detachably connected to the worktable and located below it. The output end of the cylinder is fixedly connected to the base plate and located below it. The four fixing rods are respectively fixedly connected to the base plate and located above it. The four arc-shaped seats are rotatably connected to their corresponding fixing rods and located above them. The four rubber pads are respectively fixedly connected to their corresponding arc-shaped seats and located above them. The arc-shaped ring is fixedly connected to the worktable and located above it. The pressing assembly is connected to the arc-shaped ring.

[0007] The supporting connection unit further includes a slide rod and a limiting ring. The slide rod is fixedly connected to the base plate and located above the base plate. The limiting ring is fixedly connected to the slide rod and located on the outer side wall of the slide rod. The worktable has a sliding hole, which slides in conjunction with the slide rod.

[0008] The pressing assembly includes a slide block, a pressing plate, an electric telescopic rod, and a locking component. The slide block is slidably connected to the arc-shaped ring and is located on the outer side wall of the arc-shaped ring. The electric telescopic rod is fixedly connected to the slide block and is located above the slide block. The pressing plate is fixedly connected to the electric telescopic rod and is located at the output end of the electric telescopic rod. The locking component is connected to the slide block.

[0009] The locking component includes a locking bolt and a moving block. The locking bolt is threadedly connected to the slide and is located on one side of the slide. The moving block is fixedly connected to the locking bolt and is located at one end of the locking bolt.

[0010] The pressing assembly further includes a movable slider, and the pressing plate has an irregularly shaped groove that slides in conjunction with the movable slider.

[0011] This utility model discloses a welding and positioning fixture for a fuel tank cap. During welding and positioning, a cylinder located below the worktable provides power, with its output acting upwards on a fixedly connected base plate, causing the base plate to rise and fall. Since four arc-shaped seats are rotatably connected to corresponding fixed rods, the angle of the arc-shaped seats can be adjusted according to the outline of the fuel tank cap, compressing the springs. The rubber pad precisely fits the bottom of the fuel tank cap, achieving initial positioning and buffer protection. Simultaneously, the arc-shaped ring provides an installation base for the pressing assembly. When the pressing assembly engages with the arc-shaped ring, it applies stable pressure from above the fuel tank cap, working together with the arc-shaped seats and the rubber pad to firmly position the fuel tank cap at a preset welding position above the worktable. This ensures the fuel tank cap will not shift during welding, guaranteeing welding accuracy. This method also avoids contact between the fuel tank cap and the worktable, reducing bottom wear and unnecessary costs. Attached Figure Description
