Equipment and cutter for machining inner seam allowance of part

Abstract

The embodiment of the invention discloses a cutter for machining an inner seam allowance of a part. The cutter comprises a cutter bar, a cutter seat and a boring cutter, wherein the boring cutter is arranged on the cutter seat; the cutter bar comprises a connector and an eccentric part eccentrically arranged relative to the connector; the cutter seat is sleeved on the eccentric part and can rotate relative to the eccentric part; when the cutter seat rotates relative to the eccentric part, the distance between a cutter point of the boring cutter and the center of the connector is gradually increased; a positioning pin is arranged on the cutter seat; a guide groove is formed on the eccentric part in the circumferential direction; the depth of the guide groove is gradually reduced; and the positioning pin is matched with the guide groove, so that the cutter seat is locked after rotating relative to the eccentric part. The invention also provides equipment for machining the inner seam allowance of the part. By the cutter, the inner seam allowance is conveniently machined, and the process steps of machining a process groove and adjusting a special machine can be eliminated.

Description

technical field [0001] The invention relates to the technical field of parts processing, in particular to a device and a tool for processing the inner end of a part. Background technique [0002] With the continuous improvement of bulk cargo throughput and transshipment capacity requirements in wharf, mining, chemical, electric power and other industries, the design capability of bulk material transshipment and conveying equipment stacker and reclaimer has been continuously improved. At present, the capacity of stacking and reclaiming materials per unit time has reached 10,000 tons or more, and the equipment is developing in the direction of large and super large. negative impact. In response to these problems, different types of special machines are provided in the prior art to solve the processing problems of various large-scale structural parts. However, affected by the functional limitations of the special machine itself, when machining workpieces with inner spigots, s...

Problems solved by technology

[0004] Since the inner stop of this type of bushing is larger than the diameter of the shaft hole (usually a stepped hole), it cannot be clamped if a process groove is not processed in advance at a suitable position of the inner stop when processing the inner stop as a tool groove. Tool and Feed

The inner stop is usually in the middle of the shaft hole. It is very difficult to clamp the tool, check it, and check it between processes. It needs multiple cutting, testing, tool setting and re-cutting to meet the requirements. The work efficiency is very low and the operator has high requirements.

In addition to the long time required for calibration and tool setting during processing, the special plane needs to be moved twice and positioned three times. The shift of the special plane requires the cooperation of driving and lifting workers. Equipment such as sub-tables and work card measuring tools greatly increase the processing cost
