Expansion mold locating mechanism for production of washing machine internal cylinder

Abstract

The invention relates to an expansion mold locating mechanism for production of a washing machine internal cylinder. The expansion mold locating mechanism for the production of the washing machine internal cylinder comprises a working table, the working table is provided with a rotatable hollow rotating shaft, and the hollow rotating shaft is sleeved with an expansion and shrinkage device. The hollow rotating shaft can rotate to drive the whole expansion and shrinkage device to rotate, a pull rod drives a sliding sleeve to carry out pull-up movement, the sliding sleeve drives an internal wedge-shaped sliding block to be pulled up, an external wedge-shaped sliding block and a push plate are driven to move outwards in the radial direction accordingly, the push plate pushes a mold body, radial expansion of the mold body is achieved under the action of a guide groove, and a reset spring is stretched. In a similar way, the pull rod moves downwards, the sliding sleeve descends, the push plate shrinks radially, the reset spring drives the mold body to shrink, expansion and shrinkage movement is achieved flexibly, and meanwhile, the location error is further reduced through the arrangement of an upper end arc expansion mold lug and a lower end arc expansion mold lug. The expansion mold locating mechanism for the production of the washing machine internal cylinder is flexible in structure and high in expansion and shrinkage adaptability, the cylinder body of the washing machine internal cylinder can be located effectively, the location error is small, and the needs of flow line production are met.

Description

technical field [0001] The invention relates to an expanding mold positioning mechanism, in particular to an expanding mold positioning structure used in the production of washing machine inner barrels. Background technique [0002] In the prior art, the expansion mold positioning mechanism suitable for the processing of thin-walled cylindrical products (such as the cylinder of the washing machine) usually has a rough and inflexible structure, and poor adaptability to the product during the expansion and contraction process, resulting in large positioning errors , It is difficult to adapt to the needs of automated assembly line production. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned problems in the prior art, and provide an expansion mold positioning mechanism for the production of the inner cylinder of the washing machine. The error is small, so as to meet the needs of assembly line production. [0004] The p...
