Combined machine tool for boring rocker arm holes

Abstract

The invention provides a combined machine tool for boring rocker arm holes. The total layout of the combined machine tool is a horizontal two-sided machining type layout shaped like a Chinese character 'pin', a middle base is a main body, the two ends of the top face of the base are provided with boring racks, and a clamp is arranged at the back end of the base. The two side faces of the base areconnected with side bases. Each side base is provided with a sliding table, a sliding seat, a feeding box and a boring head. One side of the base is used for machining a large hole. The opposite sideof the base is used for machining a lead screw hole, and a roller and a support capable of supporting a large boring rod are arranged on the side. A suspended type manipulation station is arranged above the clamp. A small boring rod and the large boring rod are connected with the boring heads correspondingly through connectors. The boring heads are connected with variable-frequency motors and arranged on the sliding tables. The sliding tables are arranged on the sliding seats. The sliding seats are connected with the feeding boxes. The feeding boxes are connected with the corresponding variable-frequency motors. The outer circular face of the large boring rod is provided with a cutter head. The cutter head is provided with a boring cutter body. A boring cutter is connected with the boringcutter body through a fastening screw. The boring cutter body is provided with a graduated disk. The combined machine tool for boring the rocker arm holes solves the problems of quality and work efficiency, can meet requirements of multi-variety and small-batch production manners and furthermore can achieve that an ordinary technician takes charge of multiple machines.

Description

technical field [0001] The present invention is a combination machine tool used for drilling, boring and plane scraping on the big hole and screw hole of the rocker arm, which is an important large part of a radial drilling machine, and specifically relates to a combination machine tool for boring "rocker arm" holes. Background technique [0002] Among the metal cutting machine tools, the radial arm drilling machine has the most special overall layout, and the "rocker arm" is characterized by a long, heavy, technically demanding large hole at one end of the part. During the processing, this special type of workpiece is difficult to clamp and lacks. effective technological means. It can be said to be a recognized "blocker" in the drilling machine industry. The following table lists the main data of several typical rocker arms for discussion. [0003] Product number Total length of rocker arm mm Rocker weight kg Large hole diameter mm Total length of ...

Problems solved by technology

[0008] This method is not effective, the processing quality is difficult to guarantee, the work efficiency is low, and the damage to the boring machine is extremely large. A boring machine worth 400,000 yuan to 1 million yuan will lose its accuracy and be severely worn in less than a year.

[0009] In response to this difficulty, several large drilling machine manufacturers in China launched several special machines with similar layouts, which liberated the boring machine and improved work efficiency. : The dimensional accuracy of the hole is unstable, the roughness cannot meet the requirements, and the operator's technical requirements are relatively high. Ordinary operators can't do this job well without special training.
