Multi line cutting machine swing drive structure

Abstract

The invention relates to a multi line cutting machine swing drive structure comprising a transmission portion. The front end of the transmission portion is provided with a power portion,the rear end of the transmission portion is provided with a swing head, and the middle of the transmission portion is provided with a vertical moving portion; the lower portion of the swing head clamps a workpiece blue gem bar; cutting grid lines are located under the swing head. The structure has the advantages that the structure of the swing head is simplified greatly, the swing head can be placed outside a cutting chamber for tightness and water proofing, the structural weight of the swing head is reduced, the rotating inertia is reduced, and the operation reaction is more flexible; the size of the swing head is reduced, and the spatial arrangement of a machine is facilitated; the problem of poor tightness of key portions is avoided, and the service life of the mechanism components is prolonged; in addition, the structural operation is simple, the assembling and disassembling time of the swing mechanism is shortened effectively for workers, and the maintaining and repairing efficiency is improved.

Description

technical field [0001] The invention relates to a swing driving structure for a multi-wire cutting machine. Background technique [0002] At present, the swing structure on the traditional multi-wire cutting machine mostly adopts gear transmission and arc guide rail structure. After the motor is converted by the reducer, the gear drive drives the slider to move on the arc guide rail. There are many intermediate conversion links in this structure, and various errors accumulate and are difficult to control, resulting in limited swing accuracy. The power parts such as the motor and the reducer, the transmission parts such as the transmission shaft, the gear and the slider guide rail are all located above the swing head and connected together. The complex structure requires very high assembly requirements, and there is more moisture in the cutting room, which will affect the sealing and waterproof of the parts. Rust prevention puts forward higher requirements; the traditional s...

Problems solved by technology

After the motor is converted by the reducer, the gear drive drives the slider to move on the arc guide rail. This structure has many intermediate conversion links, and various errors accumulate and are difficult to control, resulting in limited swing accuracy.

The power parts such as the motor and the reducer, the transmission parts such as the transmission shaft, the gear and the slider guide rail are all located above the swing head and connected together. The complex structure requires very high assembly requirements, and there is more moisture in the cutting room, which will affect the sealing and waterproof of the parts. Rust prevention puts forward higher requirements; the traditional structure of the swing head has a large volume and moment of inertia, which is not convenient for space arrangement and will greatly reduce the fatigue life of the parts under continuous working conditions
