Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction, in particular to a metal bracket processing fixture. Background Art

[0002] Metal brackets are rod-type brackets made of metal materials. Metal brackets are widely used, widely used to support mechanical equipment and buildings. At present, when metal brackets are cut, in order to ensure the accurate cutting position of the metal bracket, the metal bracket needs to be clamped and fixed.

[0003] The U-shaped fixing box is fixedly mounted on both sides of the top of the workbench, and the bottom ends of the two U-shaped fixing boxes are fixedly mounted. Through holes are provided on both sides of the inner walls of the two U-shaped fixing boxes, and a slide groove is provided at the bottom end of the interior of the two U-shaped fixing boxes. Two sliders are slidably connected to the inside of the slide groove with positive and negative screw rods on both sides of the inner wall of the slide groove, and the two ends of the positive and negative screw rods are threadedly connected to the middle of the corresponding sliders. The tops of the two sliders are fixedly mounted with L-shaped fixing columns, and the two L-shaped fixing columns are interlaced and connected with the corresponding through holes. A first servo motor is fixedly mounted on one side of the U-shaped fixing box, and the output shaft of the first servo motor is fixedly connected to one end of the positive and negative screw rods. The rotation of the positive and negative screw rods drives the two sliders to move toward the middle through the positive and negative screw rods, drives the L-shaped fixing column to move, and then fixes the metal bracket placed in the middle of the two U-shaped fixing boxes, and realizes the processing of metal brackets at different angles through the cooperation of the second servo motor, worm, worm wheel, transmission shaft and base plate. However, in actual use, the clamp can only clamp the metal bracket accordingly in the horizontal plane. Then, when the clamped surface of the metal bracket is an arc surface, the metal bracket is prone to slip and clamp in the vertical plane during subsequent processing, thereby affecting the processing effect of the metal bracket, and excessive clamping can easily damage the clamped surface of the metal bracket, reducing the overall quality of the metal bracket, and the clamp cannot perform convenient spacing adjustment, so that the clamp cannot effectively clamp and fix the metal bracket of shorter length, resulting in limited application scope of the clamp.
