The present disclosure provides a clamping jaw assembly and a drill chuck, which solve technical problems of complex structure, small clamping range, poor clamping effect, and high cost of the existing clamping jaw assembly. The clamping jaw assembly includes a first clamping jaw and a second clamping jaw, both of which include a screwing section, an outer surface of each screwing section is arranged with a thread, a top end of each screwing section is arranged with a clamping section, the screwing section is fixedly connected with corresponding clamping section. An inner side of the clamping section of the first clamping jaw includes a first clamping part, and an inner side of the clamping section of the second clamping jaw includes a second clamping part matched with the first clamping part. The present disclosure can be widely used in fields of electric tools, machine tool accessories and medical equipment, etc.

A chuck main body type and claw type deciding table and a pusher type deciding table are memorized in advance, information related to a leaded component such as component size, lead pitch, lead diameter, and component form is acquired, a combination of the chuck main body type and the claw type is searched from the chuck main body type and claw type deciding table using the acquired component size, lead pitch, lead diameter, and the like as search terms, the pusher is searched from the pusher type deciding table using the acquired component form or the like as a search term, and the search results are displayed. By this, it is possible to automatically select a tool made from a combination of multiple configuration members.

A chuck device includes a plurality of types of chuck pawls clamping a component, a chuck pawl switching mechanism switching the chuck pawls in use among the plurality of types of chuck pawls in accordance with the type of the component to be clamped, and a driving mechanism allowing the chuck pawl switched by the chuck pawl switching mechanism to be put into a clamping operation. The chuck pawl switching mechanism is configured to use a cylindrical cam, the plurality of types of chuck pawls are placed at predetermined intervals around the cylindrical cam, a cam follower disposed in each of the chuck pawls is fitted into a cam groove in an outer peripheral surface of the cylindrical cam, and the respective chuck pawls are moved upward and downward independently of each other by the cylindrical cam being rotated.
