Description

Workpiece feeding trolley capable of achieving accurate positioning

Technical Field

The utility model belongs to the automobile assembling field, concretely relates to last dolly of accurate location.

Background

Some smallclothes need artifically to go up the piece in welding the loading workshop, and artifical piece inefficiency of going up leads to this station to become the JPH bottleneck, and to this station staff, intensity of labour is too high to but the flexible production operation. In addition, the problem of inaccurate positioning exists in the manual loading process.

SUMMERY OF THE UTILITY MODEL

The specific technical scheme is as follows:

a precisely positioned workpiece feeding trolley comprises: the automatic feeding device comprises a bottom positioning mechanism and an upper trolley;

the bottom positioning mechanism comprises a base, wherein a cylinder is arranged on the base, proximity switches are arranged on two sides of the cylinder, a rough guide is arranged on two sides of the base, a plurality of cam followers are uniformly arranged on the two sides of the base, supporting frames are arranged at the outer ends of two sides of the base, and a photoelectric sensor and a corresponding base connecting block are arranged on the supporting frames;

the workpiece loading trolley is a welding frame, the front end of the bottom of the workpiece loading trolley is provided with two fixing feet, the rear end of the bottom of the workpiece loading trolley is provided with a universal foot, a handle is arranged on the side of the welding frame, the welding frame is provided with a plurality of base plates, modular fixtures with different heights are arranged on the base plates, and each modular fixture comprises a positioning block, a positioning connecting block and a limiting block;

the workpiece feeding trolley can be clamped and placed on the inner sides of the rough guides on the two sides of the base.

Furthermore, guide rails are arranged on two sides of the welding frame and are correspondingly matched with cam followers arranged on the base.

Furthermore, the locating piece comprises key seat and locating pin, the stopper is L type, installs a plurality ofly on the base board as required.

The working principle is as follows: adopt the accurate positioning frame, universal gyro wheel is used to the bottom, and the frame is superior Base board, uses the modularization anchor clamps to install on the Base board, can supply the part of different grade type to go up the use by the flexibility. Installing a fine positioning structure and a clamping structure on the ground of an upper workpiece opening, sensing whether the fine positioning trolley exists or not by a proximity switch, and returning to a PB operation box to press a finishing button after a worker pushes the fine positioning trolley in place, so that the fine positioning trolley is clamped by the clamping mechanism; after the parts on the fine positioning trolley material rack are taken out, the staff presses the opening button, the clamping mechanism is loosened, the staff pulls out the fine positioning trolley, and the parts are sequentially fed in a circulating manner.

The utility model has the advantages that: the problem of low efficiency of manual workpiece feeding is solved, the JPH bottleneck is overcome, and the working intensity of workers is reduced.
