Crab-shaped automatic climbing jig and method for bars and feeding equipment

Abstract

The invention provides a crab-shaped automatic climbing jig and method for bars and feeding equipment. The crab-shaped automatic climbing jig comprises a rack with a clamping platform, a bottom layer lifting mechanism, a middle layer climbing mechanism and a top layer clamping mechanism, and a feeding through groove is formed in the clamping platform; the middle-layer climbing mechanism comprises a floating seat located under the feeding through groove, climbing racks are symmetrically clamped on the two sides of the floating seat, conical teeth are arranged on the two sides of the floating seat in a protruding mode, sawtooth clamping grooves are formed in the side walls of the climbing racks, the conical teeth and the sawtooth clamping grooves are meshed to form directional limiting clamping connection, and the climbing racks are in translation driving connection through a climbing power device. The Z-direction reference bearing position is effectively changed through matched operation of the driving assembly and matching of a sawtooth clamping groove like a crab claw, and the Z-direction reference bearing position can be applied to machining of materials with different lengths or the materials can achieve the automatic lifting function. The application range of the jig is expanded, the flexibility and adaptability are improved, meanwhile, the cutting step is omitted, manpower and machining time are shortened, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to an automatic feeding device, in particular to a crab-shaped automatic climbing jig for bars, a method and feeding equipment. Background technique [0002] The traditional processing methods of existing fixtures are as follows: [0003] (1) First process the bar to a fixed length using a "cutting machine". [0004] (2) The material is placed on the A datum plane. [0005] (3) Start the cylinder to pull down and drive the push block to hold the bar workpiece. [0006] Generally, the Z-direction bearing reference height of the CNC machining tool remains unchanged, that is, the Z-direction height of the product bearing reference block cannot be changed. In the prior art, a uniform cutting process is required for materials of different lengths, thereby increasing Processing procedures prolong production time, occupy labor and a large number of production resources, resulting in a d...

Problems solved by technology

[0006] Generally, the Z-direction bearing reference height of the CNC machining tool remains unchanged, that is, the Z-direction height of the product bearing reference block cannot be changed. In the prior art, a uniform cutting process is required for materials of different lengths, thereby increasing Processing procedures, prolonging the production time, occupying labor and a large number of production resources, resulting in a decline in revenue

And it cannot adapt to processing bars of different lengths, so there are defects such as poor adaptability and single function
