Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a positioning device for steel cutting. Background Art

[0002] Steel is an iron-carbon alloy with a carbon content generally ranging from 0.02% to 2.11%. The properties of steel can be optimized by adjusting its chemical composition and heat treatment process to meet different application requirements. Steel has high strength, good plasticity and toughness, weldability, and in some cases, corrosion resistance. These characteristics make steel the material of choice in many fields such as construction, transportation, and machinery manufacturing. When processing steel, the raw steel material needs to be cut into specific sizes and shapes according to design requirements. In order to ensure that the cut steel size meets the design drawings or processing requirements, a positioning device for steel cutting is required.

[0003] In the existing technology, when cutting steel, the operator can place the workpiece on the positioning table and use the clamp provided to fix and position it, ensuring the accuracy and repeatability of steel cutting, thereby improving processing accuracy and product quality. When using the processing positioning table for cutting operations, the steel structure needs to be continuously pushed toward the saw blade, but the traditional feeding method is that the operator hoisted or lifted the steel structure to the saw blade, which is time-consuming and labor-intensive to operate and inefficient. Utility Model Content

A limiting assembly is provided on the top of the front mounting frame, and the opposite sides of the two mounting frames are fixedly connected to an electric push rod, and the output ends of the two electric push rods are fixedly connected to the clamping plate.

[0006] The top of the moving rod is fixedly connected to the anti-falling block, and the bottom of the moving rod is rotatably connected to the lever, and the lever is rotatably connected to the connecting rod at one end away from the moving rod, and the bottom of the connecting rod is rotatably connected to the pressure plate, and the inside of the pressure plate is slidably connected to the support plate, and the bottom of the support plate is fixedly connected to the top of the cutting platform.

[0013] The working principle and beneficial effects of the utility model are as follows:

[0014] 1. In the utility model, the driving gear is rotated by starting the motor. Due to the meshing between the driving gear and the driven gear, the driven gear is driven to rotate. At the same time, the rotation of the driven gear drives the rotating rod and the disc to rotate, and further rotates the limit disc and the push rod. When the push rod rotates one circle, it will drive the intermittent disc to rotate a quarter of a circle under the action of the slot, thus realizing the intermittent rotation of the intermittent disc. When the intermittent disc rotates, it will drive the connecting shaft to rotate, and then drive the conveyor belt to work, thereby realizing intermittent automatic feeding, saving time and labor, and no need to feed by manual lifting or hoisting.

[0015] 2. In the utility model, the rotation of the intermittent disk drives the synchronous wheel 1 to rotate, and the synchronous wheel 1 drives the synchronous wheel 2 to rotate synchronously through the synchronous belt. When the synchronous wheel 2 rotates, it drives the turntable to rotate, and the turntable drives the eccentric shaft to rotate. The eccentric shaft drives the hollow frame to slide up and down and perform reciprocating motion. The hollow frame drives the top moving rod to slide up and down inside the fixed frame to perform reciprocating motion. At the same time, the bottom moving rod pushes the lever to swing up and down inside the support plate. The other end of the lever drives the pressure plate to slide up and down on the outside of the support plate through the connecting rod to perform reciprocating motion, thereby pressing the steel.
