Description

Part positioning mechanism Technical Field The utility model belongs to the technical field of part positioning, and particularly relates to a part positioning mechanism. Background At present, the automatic part feeding equipment in the injection molding industry is insufficient in precision in the part positioning technology due to the existing mode, so that unstable production is often caused in the automatic production process of parts, the layout of the injection mold is multi-cavity along with the technical development, and the requirement and the production efficiency of a positioning mechanism on the automatic part feeding equipment are higher and higher. The multicavity means that the part needs the multiunit, can be arranged accumulated error and material thickness inhomogeneous and dimensional tolerance problem and lead to the positioning accuracy not enough to the material loading is unstable, and this has certain bad risk to production, like clearance too big, offset etc. easily influences product wholeness ability. However, the traditional positioning mechanism in the market is complex in operation, consumes a large amount of time, reduces the production efficiency, has high labor cost, has poor adaptability, and cannot achieve the conditions of simultaneous and accurate positioning of multiple groups of parts, difficult effective and accurate positioning of the same type of parts with different specifications and sizes, and the like. In view of the above, it is important to design and manufacture a part positioning mechanism capable of overcoming the above-mentioned problems. Disclosure of utility model Aiming at the technical problems that the multi-cavity layout of an injection mold in the prior art is easily affected by uneven material thickness and dimensional tolerance, so that the positioning accuracy of parts is insufficient, the parts are easily scratched, and the feeding stability of automatic part feeding equipment is further affected, the utility model provides a part positioning mechanism. The utility model provides a part positioning mechanism which comprises a positioning base used for placing a plurality of groups of parts, wherein an alignment assembly used for mutually aligning and clamping the groups of parts is arranged on the positioning base, the alignment assembly comprises a driving part and a clamping part, and the driving part drives the clamping part to reciprocate towards one side where the parts are located, so that the simultaneous alignment and clamping of the groups of parts are realized. The part positioning mechanism can realize quick alignment and clamping operation of multiple groups of parts on automatic part feeding equipment, greatly improves positioning efficiency and is beneficial to improving overall production efficiency. The mechanism can process a plurality of groups of parts at one time, and compared with a mode of positioning the parts one by one, a great amount of time is saved. Meanwhile, the driving part drives the design of the clamping part, so that the positioning operation is more accurate, errors possibly caused by manual operation are reduced, the accuracy of part positioning is effectively guaranteed, the stability of a subsequent production link is further guaranteed, the product quality problem caused by inaccurate part positioning, such as overlarge product gap and position deviation, is reduced, and powerful support is provided for automatic production. Preferably, the clamping portion comprises a clamping jaw, and the clamping jaw is detachably connected with the driving portion.
