Technical Field

[0001] This utility model belongs to the technical field of the power transmission line tower manufacturing industry, and in particular relates to an automatic clamping and positioning device for steel pipes. Background Technology

[0002] The manufacturing of steel pipe tower components is crucial in the production of power transmission line towers, but existing automatic clamping and positioning devices for steel pipes have some significant drawbacks. First, these devices are typically complex in structure, increasing both manufacturing and maintenance difficulty and potentially raising the likelihood of operational errors. Second, insufficient clamping force prevents displacement during steel pipe processing, resulting in lower processing accuracy. This displacement not only reduces product quality but may also increase the difficulty and cost of subsequent processing. Utility Model Content

[0011] This utility model's automatic steel pipe clamping and positioning device effectively solves the problems of complex operation, insufficient clamping force, and low processing accuracy of traditional devices through its innovative structural design. The device's V-shaped support plate and elastic clamping plate can adapt to steel pipes of different sizes, providing stable support and appropriate clamping force to ensure that the steel pipe does not shift during processing. Simultaneously, the design of the electric push rod and sliding rail allows the clamping unit to move precisely along the guide rod in a straight line, achieving rapid automatic clamping and positioning of the steel pipe.

[0013] Figure 2 This is a front view according to one embodiment of the present utility model. Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with specific embodiments and the appendix, provides further details. Figure 1-2 The present invention will be described in further detail below. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the present invention.

[0015] This utility model provides an automatic clamping and positioning device for steel pipes, comprising two clamping units arranged opposite to each other. These two clamping units can move in opposite directions under the action of a clamping drive component. Each clamping unit includes a clamping plate 3, and the inner side of the clamping plate 3 is provided with a support plate 5. The support plate is designed in a V-shape to adapt to the shape of the steel pipe and provide stable support.

[0016] Each clamping plate is provided with at least two support plates 5, and the clamping surfaces of these support plates 5 are provided with detachable clamping plates 4, which can be easily replaced or adjusted as needed to accommodate steel pipes of different sizes. The clamping plates 4 are elastic, which allows for tight clamping while preventing excessive clamping force from deforming the steel pipe.

[0017] The clamping drive component consists of a moving guide unit and a moving drive unit. The outer side of the clamping plate 5 is connected to the moving guide unit. The moving guide unit includes a moving seat connected to the clamping plate 5 and a sliding rail 17. The moving seat is laterally slidable on the sliding rail 17. The moving seat is connected to the moving drive unit via a connector to realize the movement of the clamping plate.

[0018] The movable seat includes a movable rod 6 connected to the clamping plate 3 and a sliding block 7 mounted on the sliding rail 17. The sliding block 7 has a first sliding rod 19, and the connecting members include a first connecting rod 8 and a second connecting rod 11 connected at their ends, with an angle between them of 60-100°. The first connecting rod 8 has a first sliding groove 18, within which the first sliding rod 19 always moves; the second connecting rod 11 has a second sliding groove 12, within which the second sliding rod 14 always moves, and the second sliding rod 14 is connected to the movable drive unit. A rotating rod 9 is provided at the connection end of the first connecting rod 8 and the second connecting rod 11, and the rotating rod 9 is rotatably mounted on a base 16 at the bottom of the rail to provide flexible connection and movement.

[0019] The moving drive unit includes a drive screw seat 15 fixedly connected to the second sliding rod 14. The two drive screw seats 15 are screwed to a bidirectional screw 13, which is connected to the motor 10. In this way, the rotational motion of the motor 10 is converted into the linear motion of the sliding block 7 through the bidirectional screw 13, thereby realizing the clamping and releasing action of the clamping plate 3.

[0020] During use, adjust the position of the support plate on the clamping plate according to the specific dimensions of the steel pipe to ensure that the V-shaped support plate can stably support the steel pipe. Start the electric actuator to move the two clamping units towards each other until the clamping plate contacts the steel pipe, and set the clamping force and moving speed through the control system. Once the steel pipe is clamped and positioned as required, cutting, welding, or drilling operations can be performed. After processing is complete, reverse the electric actuator through the control system to release the steel pipe from the clamping unit. Example

[0021] Each clamping unit is equipped with a moving guide unit, which includes a guide rod 2, and a moving drive unit is an electric push rod 1. The electric push rod 1 is responsible for providing power so that the clamping unit can move precisely in a straight line along the guide rod 2, thereby realizing the automatic clamping and positioning of the steel pipe.

[0022] Through the above structural design, the automatic steel pipe clamping and positioning device can achieve rapid and accurate clamping of steel pipes, improving the efficiency and accuracy of steel pipe processing, while reducing the labor intensity of manual operation.
