Clamp for numerical control machining

Abstract

The invention relates to a clamp for numerical control machining. The clamp comprises a workbench and clamping parts; a slot is formed in the top of the workbench, and the two oppositely arranged clamping parts are arranged in the slot; each clamping part comprises a horizontally-arranged connecting plate, each connecting plate is arranged in the slot in a sliding manner through a guide structure,a supporting plate is fixed to the top of one end of each connecting plate, a plurality of contact parts are evenly distributed on the opposite sides of the two supporting plates, horizontally-arranged supporting rods are arranged on the supporting plates in a penetrating manner, one end of each supporting rod is hinged to the corresponding contact part, limiting tables are arranged at the otherends of the supporting rods, and springs are connected between the limiting tables and the surfaces, deviating from the contact parts, of the supporting plates; and the clamp further comprises a driving structure, and the driving structure is arranged on the workbench and used for driving the two clamping parts to move in the same direction or in the opposite directions. The clamp can be used forclamping various workpieces with complex appearances and different shapes, can ensure the clamping stability of the workpieces, and is worth of popularizing.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a fixture for numerical control machining. Background technique [0002] Fixture, a device used to fix the processing object in the process of mechanical manufacturing so that it occupies the correct position to accept construction or inspection. [0003] According to the characteristics of use, the types of fixtures can be divided into: universal fixtures, special fixtures, adjustable fixtures and combined fixtures.

[0004] When the existing fixtures clamp different workpieces, due to the different shapes of the workpieces, the collets used in the fixture cannot effectively clamp various workpieces. At this time, it is necessary to formulate a specific Fixtures are used to clamp the workpiece. If the number of such workpieces is small, especially when the shape of the workpiece is irregular and its surface is uneven, it is extremely unworthy to produce a specific fixture for such a small number of workpieces, but The workpiece cannot be processed without making a fixture. Therefore, it is necessary to provide a fixture that can adapt to the processing of various workpieces with complex shapes and uneven outer surfaces without affecting the stability of the workpiece clamped by the fixture.
