Chain piece machining device

Abstract

The invention relates to the technical field of crawler belt accessory machining, and provides a chain piece machining device which comprises a machine frame, a CNC controller arranged on the machine frame, a rotary workbench, a first boring mechanism, a second boring mechanism, a first drilling mechanism, a second drilling mechanism, a feeding conveying mechanism, a mechanical arm and five clamping mechanisms. a groove matched with the bottom face, away from a bolt hole, of a chain piece in shape is formed in the upper surface of each fixing base, and arc-shaped limiting grooves protruding out of the surfaces of the fixing bases are formed in the two ends of the narrow side edges of the grooves; and first movable pressing claws and second movable pressing claws are arranged on the fixing bases in mode of being capable of horizontally moving on the fixing bases and located at the two ends of the chain piece placed on clamping fixing base grooves on two sides of the arc-shaped limiting groove, and arcs shaped grooves matched with arc-shaped side portions of two ends of the chain piece are arranged on sides, facing grooves, of the first movable pressing claws and the second movable pressing claws respectively. The problems that an existing chain piece is low in machining efficiency and not accurate enough are solved.

Description

technical field [0001] The invention relates to the technical field of track accessory processing, in particular to a chain piece processing device. Background technique [0002] With the rapid development of the economy, people have higher and higher levels of quality, reliability and production efficiency of construction machinery and equipment. The chain piece is an important part of the track chain link of some large-scale mechanical engineering equipment with crawler type walking, such as cranes, cranes, bulldozers and other equipment. Usually, two left and right symmetrical chain pieces are assembled to form a section, so the two pieces in the same section The structural symmetry of the chain plate requires high precision. The chain plate body is usually a forged steel part. There are two left and right pin holes and two bolt holes perpendicular to the pin holes on the chain plate body. The pin holes are usually made during forging. The holes are preliminarily formed,...

The chain piece is an important part of the track chain link of some large-scale mechanical engineering equipment with crawler type walking, such as cranes, cranes, bulldozers and other equipment. Usually, two left and right symmetrical chain pieces are assembled to form a section, so the two pieces in the same section The structural symmetry of the chain plate requires high precision. The chain plate body is usually a forged steel part. There are two left and right pin holes and two bolt holes perpendicular to the pin holes on the chain plate body. The pin holes are usually made during forging. The holes are preliminarily formed, and then bored by a boring machine, and the bolt holes are later drilled by a drilling machine. The pin holes and bolt holes are processed separately in multiple steps and processes, and the processing efficiency is low. At the same time, because it is an important component of the track chain link, the requirements for the relative position and machining accuracy of the bolt holes are very strict, and the chain pieces of the track link are irregular shapes, so it can be bored and drilled. Effective and stable fixing of the chain can basically guarantee the processing accuracy, but the existing chain clamping is to process a chain, that is, the pin hole and the bolt hole are clamped, and the chain cannot be guaranteed when clamping the chain. The clamping positions of the chain pieces are exactly the same, and at the same time, only a single chain piece can be positioned, so that the relative positions of the pin holes and bolt holes of the two paired chain pieces are not accurate enough, and the production rate of defective products is high during processing. Simultaneous processing and production efficiency is low
