Description

Technical Field

[0001] This utility model relates to the field of chord processing technology, specifically a positioning platform for chord processing. Background Technology

[0002] A truss is a planar or spatial structure composed of straight bars and generally has triangular units. Truss members mainly bear axial tension or compression, thus making full use of the strength of the material. When the span is large, it can save material compared to a solid web beam, reduce self-weight and increase stiffness. Chords refer to the members on the upper and lower outer perimeter of the truss. The upper members are called upper chords and the lower members are called lower chords.

[0003] When machining chord members, welding, drilling, and other operations are required. Special fixtures are usually used to lock the chord members, and welding or drilling machines are used to operate them. After machining a certain position, the fixture is first used to loosen the chord member, and then auxiliary tools are used to rotate and adjust the chord member before machining another position. The operation is relatively complicated and reduces the machining efficiency of the chord members. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 3 This utility model provides a positioning platform for processing chord members, including a support frame 1 and a processing table 2 connected to the top of the support frame 1. The processing table 2 is connected to multiple V-shaped seats 3. One end of the processing table 2 is connected to a liftable side plate 4, and the other end is connected to a pushing mechanism for moving the chord members. A rotating disk 9 is rotatably connected to the side of the side plate 4. The rotating disk 9 is connected to a motor 5 for driving the rotating disk 9 to rotate, and the rotating disk 9 is connected to a clamping mechanism for clamping the chord members.

[0021] The driving mechanism includes a stud 10, a push plate 11, a rectangular hole 12, and a second motor 13. The second motor 13 drives the stud 10 to rotate, and the stud 10 drives the push plate 11 to reciprocate. The push plate 11 is slidably connected to the rectangular hole 12, which is located on the processing table 2. When the chord is placed on the V-shaped seat 3, the second motor 13 drives the stud 10 to rotate, which in turn moves the push plate 11 forward, causing the push plate 11 to push the chord to move. The end of the chord is connected to the rotating disk 9, facilitating subsequent clamping and fixing of the chord.

[0022] Motor 2 13 is connected to the end of the processing table 2, and the power output end of motor 2 13 is connected to stud 10. Stud 10 is threadedly connected to push plate 11. The end of stud 10 is rotatably connected to processing table 2, which can improve the rotational stability of stud 10.

[0023] A motor 5 is connected to the side of the side plate 4. The output end of the motor 5 is connected to a gear 15, which meshes with the rotating disk 9. When the chord is clamped, the motor 5 drives the gear 15 to rotate. The gear 15 cooperates with the rotating disk 9 to rotate the rotating disk 9, thereby driving the chord to rotate. This facilitates welding and drilling at different positions of the chord without manual operation, saving time and effort and increasing efficiency.

[0024] The clamping mechanism includes multiple sliding grooves 16, multiple clamping blocks 17, multiple push-pull plates 18, a cylinder 19, and a connector 20. The power output end of the cylinder 19 is connected to the connector 20, and the end of the cylinder 19 is fixed to the rotating disk 9. Both ends of the connector 20 are axially connected to the clamping blocks 17 and the connector 20. The sliding grooves 16 are used to guide the clamping blocks 17. Three clamping blocks 17 can be provided, with an adjacent included angle of 120°. Three matching sliding grooves 16 and three matching push-pull plates 18 are also provided. When clamping the chord, the cylinder 19 drives the connector 20 to reciprocate. The connector 20 simultaneously applies a pushing or pulling force to the three push-pull plates 18, causing the clamping blocks 17 to reciprocate on the corresponding sliding grooves 16. The three clamping blocks 17 simultaneously press against the inner wall of the chord, achieving locking and fixing of the chord, improving the stability of the chord, and is applicable to fixing chords of different diameters, making it highly adaptable.

[0025] The slide groove 16 is provided on the rotating disk 9, and the clamping block 17 is slidably connected to the slide groove 16 to improve the stability of the movement of the clamping block 17.

[0026] The support frame 1 is connected to a hydraulic cylinder 8, and the power output end of the hydraulic cylinder 8 is connected to the side plate 4. When processing chords of different diameters, the hydraulic cylinder 8 can drive the side plate 4 to rise and fall, changing the position of the rotating disk 9, so that the center line of the rotating disk 9 and the connecting head 20 coincides with the center line of the chord, making it easier for the clamping block 17 to press against the inner wall of the chord.

[0027] The side of the side plate 4 is provided with multiple positioning grooves. The machining table 2 is threadedly connected with positioning bolts 7. The end of the positioning bolts 7 matches the positioning groove. When the side plate 4 is at a suitable height, the positioning bolts 7 are rotated so that their ends are connected to the positioning grooves to achieve positioning and locking of the side plate 4. At this time, the hydraulic cylinder 8 stops.

[0028] Multiple balls 14 are movably connected to the inner side of the V-shaped seat 3. The chord is supported by the balls 14, which can avoid direct contact with the V-shaped seat 3, reduce the contact friction between the V-shaped seat 3 and the chord, and facilitate the movement of the chord.

[0029] Working Principle: When processing chord members of different diameters, firstly, hydraulic cylinder 8 drives side plate 4 to rise and fall, changing the positions of rotating disk 9, three clamping blocks 17, and connector 20. Then, positioning bolts 7 are used to lock and fix side plate 4. The chord member is placed on V-shaped seat 3. Motor 2 13 drives stud 10 to rotate, which in turn moves push plate 11, applying a pushing force to the chord member and driving it to move. The end of the chord member connects to rotating disk 9. Cylinder 19 drives connector 20 to move, which simultaneously applies a pushing or pulling force to the three push-pull plates 18, causing the three clamping blocks 17 to move synchronously. The clamping blocks 17 press against the inner wall of the chord member, locking and fixing it for easy welding and drilling operations. Motor 1 5 drives gear 15 to rotate, which in turn drives rotating disk 9, allowing the chord member to rotate at multiple angles. This facilitates processing at different positions without manual adjustment, saving time and effort, and increasing efficiency.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
