Abstract

The invention relates to a sewing machine chuck which comprises a chuck body, three sliders, three clamping claws, a positioning claw and a contracting and releasing disc. Three sliding grooves are radially distributed on the chuck body, the sliders are arranged in and can slide along the sliding grooves, the clamping claws are arranged on the sliders, the positioning claw is arranged on the chuck body, the contracting and releasing disc is arranged in the chuck body and can pull the sliders to synchronously slide in a manner of being contracted towards or being away from the center of the chuck body, a guide groove is further arranged on the chuck body radially, the positioning claw is arranged in and can move along the guide groove, a fixing member capable of fixing the positioning claw at a certain position in the guide groove is arranged on a base portion of the positioning groove, adjacent intervals between two of the sliding grooves and the guide groove are smaller than 120 degrees, the other sliding groove divides the two sliding grooves equally, and an angle formed between the moving direction of the positioning claw and the sliding direction of the slider adjacent to the positioning claw is not larger than 60 degrees. The sewing machine chuck has the advantages of convenience and accuracy in adjusting and positioning, large in controllable range, wide in application range and the like.

Description

Technical field [0001] The invention relates to a sewing machine chuck. Background technique [0002] Traditional pneumatic multi-jaw fixtures are mostly synchronous retractable fixtures, that is, multiple jaws are tightened at the same time to clamp, install or fix components. It is only suitable for regular and fixed components. When the component shape changes , You can only replace the suitable chuck. Chinese patent CN201357240Y discloses a chuck that can be adapted to elements of various shapes, and adjust the position of the jaws on the slider to correspond to elements of different shapes. But it is still synchronized retracting in nature, so each adjustment needs to be tightened and confirmed once. When the shape of the component is irregular, it needs to be corrected and confirmed many times. Therefore, there is a need for a fixture that can adapt to various shapes and even irregularly shaped components, and is convenient for adjustment and accurate positioning. Summar...
