Motorcycle throttle body machining fixture

Abstract

The invention discloses a motorcycle throttle body machining fixture. The motorcycle throttle body machining fixture comprises bulb locking and positioning mechanisms, a bridge plate, two fixture positioning units and a plurality of pressing units. Two ends of the bridge plate are connected with a tailstock of a machine tool and an L plate of an index head through the bulb locking and positioning mechanisms respectively, and the two fixture positioning units and the multiple pressing units are arranged on the bridge plate. Each fixture positioning unit comprises a fixture base, a positioning block A, a plurality of moving steel ball screw components and a positioning block B, wherein the fixture base is fixed to the bridge plate, the bridge plate and the fixture base are provided with gourd-shaped holes matched with motorcycle throttle bodies, the positioning block A, the positioning block B and positioning bosses are arranged at the edge of the gourd-shaped hole of the fixture base, each positioning boss of the fixture base corresponds to one pressing unit, and the moving steel ball screw components with pre-tightening and false-proof functions are arranged on the fixture base. The motorcycle throttle body machining fixture has advantages of accuracy in positioning, simplicity in operation, high production efficiency and high machining quality.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a motorcycle throttle body processing fixture. Background technique [0002] In the mechanical processing and manufacturing industry, especially in the processing of auto parts, there are often many varieties of small batch production. The existing fixture adopts the independent replacement design of a single fixture. The fixture needs to be replaced and debugged every time the model is changed. Therefore, the changeover time usually takes 1-1.5 days, the production efficiency is low, and the equipment utilization rate is not high. The existing fixture adds a process reference to the product, so that the processing flow has two more processes: 1. Machining two process reference positioning holes and milling process reference surface; 2. Removing the process reference (when all processes are completed), making the processing cycle longer , Low production efficiency....
