Description

Technical Field

[0001] The utility model relates to the technical field of metal structure processing equipment, and more specifically to a clamping and fixing device for metal structure manufacturing. Background Art

[0002] A clamping device generally refers to an industrial fixture, which is used to clamp and fix a certain base part of a metal structure, such as a cut steel plate or metal block, on which operations such as welding and installing the metal structure are performed after fixation.

[0003] Based on the above, the inventors have discovered that conventional clamping and fixing devices mostly utilize two clamps to clamp and fix the metal workpiece front and back, but the two clamps are clamped relative to each other, which may result in uneven force, and may easily become loose or shift in position during processing, thereby affecting the overall stability and causing large deviations in the processing of the metal workpiece, thereby reducing the efficiency of metal workpiece manufacturing. Therefore, in view of this, the inventors have studied and improved the existing structure, and provided a clamping and fixing device for metal structure manufacturing, in order to achieve a more practical purpose.

When in use, by setting the threaded hole, when the screw rod 14 is rotated, the rack 12 can be moved horizontally, and the gear ring 10 can be rotated during the movement, thereby realizing the rotation of the rotating plate 8, and with the cooperation of the guide rod 7 and the moving block 5, the position adjustment of the clamp 6 is completed, and the metal workpiece to be processed is clamped and fixed.

[0044] See also Figure 3 The outer periphery of the bottom end of the guide rod 7 is movably connected to the side wall of the arc-shaped guide hole 9. When in use, there are three arc-shaped guide holes 9, which are equidistantly distributed in a ring shape. With the cooperation of the guide rod 7, when the position of the arc-shaped guide hole 9 changes, the position of the clamp 6 on the moving block 5 can be adjusted, thereby enabling the workpiece to be clamped and fixed.

[0045] See also Figure 5 The clamp 6 includes a clamp seat 601 fixed on the top of the moving block 5.
