Description

Technical Field

[0001] The utility model mainly relates to the technical field of aluminum material processing, in particular to a fixing and clamping device for aluminum materials. Background Art

[0002] Aluminum alloys are widely used in the industry. During the processing of aluminum, the aluminum will shake, causing its own position to move, thus affecting the processing effect. Therefore, an aluminum fixing clamping device is needed to assist in the processing of aluminum.

[0003] After searching, the utility model patent with announcement number CN218926986U discloses an aluminum processing fixing device, including a base, the left and right sides of the base are fixedly connected with a box body, the inner side wall of each of the box bodies is provided with a sliding opening, the inner side wall of the base is provided with two through openings, the interior of the base is provided with two clamping plates, the inner wall of each of the sliding openings is slidably connected with a rack, the ends of the two racks close to each other respectively pass through the two through openings and are fixedly connected to the sides of the two clamping plates away from each other, and the inner top wall of each of the box bodies is fixedly embedded with a motor; this device utilizes the cooperation of the motor, the gear and the rack to facilitate the sliding of the rack inside the sliding opening and the through opening during the rotation of the gear, and according to the thrust of the rack, the clamping plates are brought close to each other and fix the aluminum material, and its fixing method is simple to operate and easy to use, which not only reduces the labor of the staff, but also facilitates and quickly clamps the aluminum material, which is conducive to speeding up the production progress of the aluminum material.

[0004] In the above patented technical solution, by utilizing the cooperation of the motor, gear and rack, the rack can slide inside the sliding opening and the through opening during the rotation of the gear, and according to the thrust of the rack, the clamping plates are brought closer to each other and the aluminum material is fixed. However, the above patented technical solution still has the following shortcomings when used:

[0005] 1. When the above patented technical solution is used, the height of the clamping plate is fixed and cannot be adjusted. When the height of the aluminum material to be clamped is very high, the center of gravity of the aluminum material will also be high. At this time, if only the bottom of both sides of the aluminum material is clamped, when the top of the aluminum material is stressed, there is still a risk of tipping over, causing damage to the aluminum material and bringing inconvenience to the processing personnel;

[0006] 2. When the above patented technical solution is used, it can only clamp regular aluminum materials, such as square aluminum materials. When the object to be clamped is a round aluminum material, the above patented technical solution cannot stably clamp and fix the round aluminum material, resulting in a decrease in the practicality of the aluminum material fixing and clamping device, affecting the aluminum material processing efficiency.
