Abstract

The utility model relates to a honing head in a grinding tool for machine tool processing, in particular to a honing head and connecting rod anti-shedding mechanism. The honing head and connecting rod anti-shedding mechanism comprises a honing head and connecting rod, and a connecting sleeve. The mechanism is characterized in that: a retainer ring and a positioning device are matched on a boss at one end of the connecting sleeve, and a restoring spring ring is arranged between the retainer ring and the positioning device; the structure is simple, the working efficiency is improved and the disassembling is convenient.

Description

Honing head and extension bar escapement

Technical field

The utility model relates to the honing head in the machine tooling grinding tool, especially relates to a kind of honing head and extension bar escapement.

Background technology

Honing head is to be fixed in the anchor clamps with the abrasive particle oilstone to form, back and forth with rotatablely moving to cooperate the mechanical part endoporus is carried out accurately machined instrument.For some mechanical parts, require its inwall to have less surface roughness usually.At present, after honing head and the extension bar assembling, cooperate pin that honing head and extension bar are fixed on the honing machine by connecing the pin-and-hole that puts, after the process finishing, remove pin dismounting honing head and extension bar down, during owing to honing head and extension bar work, main shaft is in the state of rotation at a high speed, thereby hang pin and very easily throw off and cause honing head and extension bar to fall down, reduced operating efficiency like this.

Summary of the invention

The purpose of this utility model is to overcome the defective of above-mentioned prior art, provide a kind of simple in structure, increase work efficiency, the honing head and the extension bar escapement of convenient disassembly.

The purpose of this utility model is achieved through the following technical solutions:

A kind of honing head and extension bar escapement comprise it is characterized in that honing head and extension bar and connect cover: cooperate a retaining ring and a location device on this connects an end boss of cover, be provided with a back-moving spring circle between above-mentioned retaining ring and the positioner;

The radially two ends of described retaining ring have with described connecing overlaps the boss that cooperates;

Described positioner is one to be stuck in the described locating ring that puts that connects;

Described positioner is one to be located at the described annular boss that puts that connects.

The utility model has following effect:

Honing head that the utility model provides and extension bar escapement, be to put cooperation one retaining ring, turn and positioner existing connecing, during use, move on honing head and the extension bar, rotate and hang in the cotter way, rotation retaining ring, make its radially both sides boss with connect the groove fit that puts, turn is extruded contraction simultaneously, after the two is worked good, turn resets, and blocks by turn and hangs pin, prevents that main axis rotation from stopping to hang pin disengagement honing head and extension bar falls down, thereby simplified manufacturing procedure, improved operating efficiency.
