Description

Technical Field

[0001] The utility model belongs to the field of clamps, and in particular relates to a positioning clamp for processing spring sheets. Background Art

[0002] The fixture in the prior art refers to a device used to fix the processing object in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process of the process can be called a fixture.

[0003] A Chinese patent with application number CN202121977219.9 discloses a spring sheet positioning fixture, including a clamping assembly, the clamping assembly including a base, a shell is installed on the top of the base, a fixing piece is provided on one side of the shell, and the fixing piece and the shell are slidably connected; a top plate is installed on the top of the fixing piece, an electric cylinder is installed on the bottom of the top plate, a connecting plate is installed on the output shaft of the electric cylinder, and a protective plate is detachably connected to the bottom of the connecting plate; by setting the clamping assembly, the user first turns on the hydraulic cylinder so that the output shaft of the hydraulic cylinder drives the fixing piece to move in the vertical direction to adjust the height of the loading platform, and then places the spring sheet on the loading platform, and turns on the electric cylinder so that the output shaft of the electric cylinder drives the connecting plate to move in the vertical direction until the protective plate contacts the spring sheet, thereby pressing the spring sheet against the loading platform, effectively preventing the spring sheet from moving during processing.

[0004] However, when the above-mentioned device is actually used, the positioning fixture relies on the air pump to extract the gas in the suction cup to generate adsorption force, thereby fixing the workpiece; however, this fixing method has obvious limitations; first, the adsorption force generated by the air pump is greatly affected by the stability of the air pressure and the flatness of the workpiece surface. Once the air pressure fluctuates or the workpiece surface is uneven, it may lead to a decrease in positioning accuracy or even the workpiece falling off, thereby affecting the processing quality and safety; secondly, the use of the air pump increases the complexity and maintenance cost of the equipment.

[0005] In view of this, the present utility model is proposed. Utility Model Content
