Technical field

The utility model belongs to field of textile machinery, and especially a kind of novel loom tool arm structure, the tool arm is used for Shedding and return it is comprehensive.

Background technique

Loom is common textile machine, and loom palm fibre frame lifting apertures movement thereon needs rocker arm, broaching tool, drag hook Multiple component collective effects such as engaging member, tool arm, tool arm main shaft, lifting-cord engaging member and heald frame, heald lifting arm especially therein, It returns tool arm used in comprehensive arm to be of great significance to the movement of loom palm fibre frame lifting apertures, therefore whether tool arm quality is stable right The normal work tool of loom has a significant impact.Existing common tool arm is all the magnesium iron thin-wall part using monolithic construction, is had Following defect:

The defects of 1. tool arm uses magnesium iron thin-section casting, inevitably generates stomata, sand holes, cold shut, spoken parts in traditional operas in casting, rejection rate It is high, at high cost；

2. from moulding, the production cycle for being poured into out casting is long, occupied ground is big, production capacity is low, difficulty is adopted when demand is big Purchase；

3. tool arm is thin-wall part, processing and loading clamp deformation is big, and difficulty of processing is big, dimensional accuracy is not easy to control, quality It is not sufficiently stable.

The applicant proposes patent application with regard to this, and Patent No. CN2012207250767, existing the present inventor is in this base Further improvement is just proposed on plinth, a novel loom tool arm structure is designed, to meet the needs of existing market.

Utility model content

The technical problems to be solved in the utility model is to overcome existing defect, provides a kind of novel loom tool arm knot Structure, production cost is lower than casting, the high easy buying of production capacity, handling ease quality stabilization.

In order to solve the above-mentioned technical problem, the utility model provides the following technical solution:

A kind of novelty loom tool arm structure, including tool arm bottom plate, it is characterised in that: be equipped in tool arm bottom plate one end Split joint work department, the connector work department include two stamping forming metal sheets, and two metal sheets are convex by 6 Solder joint, projection welding connection molding, forms 2 riveted holes in the connector work department, is located on tool arm bottom plate by riveting.

The utility model is done further preferably, the end of the tool arm bottom plate is formed and the matching riveting of connector work department Riveted holes.

The utility model beneficial effect achieved is compared with prior art:

The utility model includes tool arm bottom plate, is equipped with connector work department in tool arm bottom plate one end, it is characterised in that: institute Stating connector work department includes two stamping forming metal sheets, which is formed by 6 convex algorithms, projection welding connection, 2 riveted holes are formed in the connector work department, are located on tool arm bottom plate by riveting.The utility model passes through split type Connector work department and tool arm bottom plate are separated, and are riveted each other by rivet by structure, integral way flexible and convenient, in addition Connector work department is easy securely by projection welding connection molding, welded connecting by two stamping forming iron plates, has manufacturing cost The advantages that low, dimensionally stable, wearability combine well and facilitate.
