Description

Technical Field

[0001] The utility model relates to the technical field of intake manifolds, in particular to an intake manifold welding and fixing device. Background Art

[0002] The intake manifold is an important component of the engine, mainly used to introduce air into the engine. The intake manifold is usually made of metal or plastic and has multiple intake holes or intake ports. It is used to connect the air filter and the engine's intake duct. The design and shape of the intake manifold have an important influence on the performance of the engine. It can control the speed and direction of the intake air flow to provide optimal combustion conditions. The intake manifold can also increase the engine's torque and power output by changing its length and shape. The intake manifold is an important component in the engine, and its design and function have a direct impact on the engine performance.

[0003] Welding is a common metal processing method that heats metal to a high temperature to melt it and connect it with other metal materials. Welding usually uses filler materials such as welding rods, welding wires or welding cores, and heats the metal materials together through energy sources such as electric arcs, gas flames or electron beams. Welding technology is widely used in industrial manufacturing, construction, aerospace and other fields to manufacture and repair various metal products and structures. Welding can connect different types of metals, such as steel, aluminum, copper, etc., and can also connect metals of the same type. The connection strength of welding is usually very high and can withstand greater force and pressure. Intake manifold welding usually adopts argon arc welding or arc welding. By using suitable welding materials, the joints of the intake manifold are heated to a sufficient temperature to melt it and connect other metal materials together.

[0004] In the prior art, when welding the intake manifold, the operator is generally required to align the two ends of the intake manifold and keep it fixed at all times, which is inconvenient when spot welding. The spot welding position is prone to offset, causing leaks when repairing the connection of the intake manifold, which will affect the engine's air intake. Based on this problem, we proposed an intake manifold welding fixture. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 The intake manifold welding fixing device comprises a sleeve 1, and two hanging rings 2 are fixedly connected to the outer wall of the sleeve 1. The hanging ring 2 can be used to hang the device, which is convenient for placing the sleeve 1. A through groove is provided in the sleeve 1, and a fixing seat 4 is threadedly connected to the outer wall of the sleeve 1. The fixing seat 4 and the sleeve 1 are threadedly connected, which is convenient for the operator to adjust the vertical position of the fixing seat 4 on the side wall of the sleeve 1. The fixing seat 4 is fixedly connected to the opposite side walls of the fixing seat 4, and the clamping device comprises a connecting column 5 fixedly connected to the side wall of the fixing seat 4. A connecting rod 6 is threadedly connected to the connecting column 5. The connecting rod 6 is an L-shaped rod, and an arc plate 7 is fixedly connected to the other end of the connecting rod 6.

[0021] Specifically, a welding gun body 3 is arranged through the through groove, and an elastic device is elastically connected to the inner wall of the through groove at a corresponding position, and the elastic device includes a spring 10 elastically connected to the inner wall of the through groove, and a connecting ring 9 is elastically connected to the upper end of the spring 10. A positioning ring 8 is threadedly connected to the outer wall of the welding gun body 3 at a corresponding position. When the welding gun body 3 is inserted into the through groove, the positioning ring 8 and the connecting ring 9 are abutted, and the spring 10 is arranged on the inner wall of the through groove at the bottom.

[0022] It is worth mentioning that the inner walls of the two arc-shaped plates 7 are provided with anti-skid pads, which can play an anti-skid role. When the arc-shaped plates 7 are against the anti-skid pads, they can avoid relative sliding, which causes the spot welding position to change, making it easier for operators to position.

[0023] In the utility model, when the sleeve 1 in the device needs to be used, the operator can insert the welding gun body 3 into the through groove, and position the two arc plates 7 on both sides of the sleeve 1 corresponding to the positions on both sides of the manifold. The vertical height of the two arc plates 7 can be adjusted by rotating the corresponding fixing seat 4. The arc plates 7 on both sides can be rotated to adjust the spacing between the two arc plates 7 through the connecting column 5 and the connecting rod 6. After the two arc plates 7 are against the two sides of the manifold, the corresponding welding gun body 3 is pressed down, and the corresponding positioning ring 8 and the connecting ring 9 drive the spring 10 to undergo compression deformation, so that the welding gun body 3 can be spot welded, which is convenient and quick. After the spot welding is completed, the device can be directly removed from the welding gun body 3 and can be directly separated. The operation is simple, and the device can be placed later by the two hanging rings 2 provided, and can be reassembled when needed.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
