Description

Technical Field

[0001] This utility model relates to the field of diesel engine pipeline technology, and in particular to a flange chuck for welding diesel generator pipelines. Background Technology

[0002] Diesel generator sets are widely used in industrial production, construction, emergency power supply and other fields. The welding quality of diesel engine pipelines directly affects the performance and safety of the generator. Traditional welding methods often rely on manual operation, which has problems such as inaccurate positioning, insufficient welding strength and uneven weld seam. This not only affects welding efficiency, but may also lead to hidden dangers such as leakage and failure in subsequent use. Therefore, a welding tool that can improve welding accuracy and reliability is needed.

[0003] While some welding fixtures and flange chucks exist on the market, most are relatively simple in design and cannot meet the high requirements of diesel generator pipeline welding for flange angles and positions. For example, traditional chucks often struggle to achieve rapid and precise positioning when adjusting and fixing welding workpieces, and lack sufficient stability, leading to workpiece movement or deformation during welding. Furthermore, fixtures lacking adjustment functions often require replacement when welding flanges of different sizes and shapes, increasing workload and time costs. Therefore, we propose a flange chuck for diesel generator pipeline welding to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a flange chuck for welding diesel generator pipelines, in order to solve the problems of poor positioning accuracy, poor stability, and lack of adjustment function to adapt to various flange specifications of existing welding flange chucks.

[0005] To solve the above-mentioned technical problems, this utility model provides a flange chuck for welding diesel generator pipelines, including a chuck, a limiting straight groove opened in its middle and passing through it, and a clamp with a circular groove at the center of the chuck;

[0006] Chuck base, the chuck is mounted on the chuck base;

[0007] The adjustment assembly includes a bidirectional lead screw disposed in the limiting straight groove, a knob handle disposed at both ends of the bidirectional lead screw, and a pair of T-shaped sliders mounted on the bidirectional lead screw. The knob handles are connected to both ends of the bidirectional lead screw by cylindrical pins, and the bidirectional lead screw can be driven to rotate by the knob handles.

[0008] The connector, chuck and chuck base are fixed together by multiple set screws around them. A flat key is provided at the bottom of the chuck base, which is fixedly connected to the chuck base and installed on the positioning column by fixing screws.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0021] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0023] This utility model provides a flange chuck for welding diesel generator pipelines. Please refer to [link / reference]. Figures 1-3The system includes a chuck 1, which has a limiting straight groove 101 that extends through its middle, and a caliper 102 with a circular groove at its center; a chuck base 2 on which the chuck 1 is mounted; an adjustment assembly 3, which includes a bidirectional lead screw 301 disposed in the limiting straight groove 101, knob handles 302 disposed at both ends of the bidirectional lead screw 301, and a pair of T-shaped sliders 303 mounted on the bidirectional lead screw 301. The knob handles 302 are connected to both ends of the bidirectional lead screw 301 by cylindrical pins 304, and the bidirectional lead screw 301 can be driven to rotate by the knob handles 302; and a connecting piece 4, which fixes the chuck 1 and the chuck base 2 by a plurality of set screws 401 surrounding it. A flat key 402 is provided at the bottom of the chuck base 2, which is fixedly connected to the chuck base 2 and mounted on a positioning column 404 by fixing screws 403.

[0024] The chuck 1 also includes multiple positioning holes 103 on its outer side; the outer edge of the chuck 1 is provided with angle scale lines 104; the T-shaped slider 303 is fitted onto the bidirectional lead screw 301, and the two T-shaped sliders 303 are symmetrically distributed relative to the center of the chuck 1; the contact surfaces of the top support 202b and the support pipe support 102 with the long pipe 4 are anti-slip surfaces; the outer side of the T-shaped slider 303 is provided with flange mounting holes 303a for fixing the flange.

[0025] It should be noted that both the chuck 1 and the chuck base 2 are made of cast iron material with good wear resistance and shock absorption performance. The caliper 102 is a circular groove located in the center of the chuck 1, used to clamp some small flanges and clamp them through the T-shaped slider 303.

[0026] Better, such as Figure 2 As shown, the chuck 1 is embedded in the chuck base 2, and the two can rotate relative to each other on the same axis to adjust the angle of the chuck 1. An angle scale line 104 is provided on the outer edge of the chuck 1, which is marked with a precise scale line from 0 degrees to 359 degrees. When the flange needs to maintain a certain angle with the pipe during welding, the chuck 1 can be rotated and adjusted to the required angle scale. Finally, it is fixed by multiple set screws 401 on the outer wall.

[0027] Better, combination Figure 1 and Figure 3 As shown, the flange chuck is fixedly installed to the positioning column 404 by fixing screws 403 passing through the flat key 402 or the chuck base 2. The positioning column 404 can drive the flange chuck to move up, down or rotate, so that the position of the flange can be changed more three-dimensionally and comprehensively, ensuring that it can be adjusted to the required position during processing or welding, which significantly improves the flexibility of welding operations.

[0028] Preferably, the position of the bidirectional lead screw 301 is adjusted by a knob handle 302. The knob handle 302 is fixedly connected to both ends of the bidirectional lead screw 301 by a cylindrical pin 304. The T-shaped slider 303 has a threaded hole that meshes with the bidirectional lead screw 301. The threaded hole passes through the bidirectional lead screw 301 and engages with it. When the knob handle 302 is rotated, the T-shaped slider 303 is limited by the limiting straight groove 101 and can only move linearly along the straight groove. The bidirectional lead screw 301 is divided along the center, with threads of different directions on both sides. Therefore, the T-shaped sliders 303 at both ends can only retract or expand synchronously. The center point between the two T-shaped sliders 303 is still the center of the chuck 1. When the flange is installed on the T-shaped slider 303 through the flange mounting hole 303a, its position is still the center of the corresponding chuck 1. In this way, the flange positioning is very accurate and easy to adjust, and it can adapt to the fixing of flanges of different specifications.

[0029] In summary, this utility model of a flange chuck for welding diesel generator pipelines, by setting a limiting straight groove and a two-way screw, allows the T-shaped slider to retract or expand within the limiting straight groove using a knob handle. This enables flexible adjustment of the distance between the two flange mounting holes, accommodating the fixing of flanges of different specifications. Simultaneously, the chuck is also equipped with multiple pairs of fixing positioning holes, allowing for direct fixing of some commonly used flange specifications without adjustment. This design greatly improves the chuck's adaptability and increases work efficiency. Furthermore, the chuck and chuck base can rotate relative to each other, and the rotation angle can be precisely adjusted via an angle scale to adjust the flange angle fixed on the chuck. After adjustment, it is fixed with set screws. During installation, the flange can be adjusted in multiple directions using the lifting and lowering of the positioning column, ensuring it can be adjusted to the required position during processing or welding, significantly improving operational flexibility.

[0030] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
