摘要： A drill-chuck jaw is made by first forming an elongated metal body with a toothed back face and a front face, then machining a longitudinally extending groove having sides and a floor in the front face, and forming inwardly projecting and longitudinally spaced retaining bumps on the groove sides. A hard-metal insert is fitted into the groove between the retaining bumps and then bonded to the body in the groove. the body is heat-treated, that is annealed, before machining the groove in it to reduce internal stresses. Then the body is cleaned and oiled to prepare it for machining and to eliminate any oxidation created by the heat treatment. After machining the body and before fitting the insert the body is deburred and cleaned again. Normally the insert is bonded to the body by soldering or brazing. In order to allow the insert to seat directly on the jaw and not be held off it by the solder a channel is formed between the insert and the body in the groove. The insert is bonded to the body by filling the channel with the solder. The channel can be formed in the insert or in the body.
摘要翻译：通过首先形成具有齿背面和前表面的细长金属体，然后在前表面上加工具有侧面和底板的纵向延伸的凹槽，并且形成向内突出的和纵向间隔的保持凸块，来制造钻卡盘卡爪槽边。将硬金属插入件装配在保持凸块之间的凹槽中，然后在凹槽中结合到主体。在机加工凹槽之前，对体进行热处理，即进行退火处理，以减少内部应力。然后将身体清洁并加油，以准备加工，并消除热处理产生的氧化。加工身体后，在装配插入物之前，将身体再次去毛刺和清洁。通常，插入件通过焊接或钎焊结合到主体。为了允许插入件直接安置在钳口上，并且不被焊料挡住，插入件和槽体中的主体之间形成通道。通过用焊料填充通道将插入物接合到身体。通道可以形成在插入物中或体内。

摘要： A drill chuck has a chuck body centered on and adapt d to be rotated about a longitudinal axis and unitarily formed with a plurality of forwardly open angled guides angularly spaced about the axis and with a rim, respective jaws displaceable along the guides in the chuck body and each formed with a row of teeth, and a tightening sleeve rotatably surrounding the body. A threaded ring rotatable on the body about the axis within the tightening sleeve is fixed to the sleeve and formed with a screwthread meshing with the teeth of the jaws so that rotation of the ring in one direction moves the jaws radially together and opposite rotation moves them radially apart. This threaded ring is formed with a radially outwardly open groove covered by the sleeve. In addition the tightening sleeve has an inwardly projecting welt engaged in the groove.

摘要： A drill chuck has a chuck body centered on an axis and forming an axially forwardly open bit-receiving recess, an axially forwardly open polygonal-section seat at a base of the recess, and a plurality of jaws spaced angularly around the seat. The jaws can be displaced radially inward and outward to grip a bit in the recess. An element can move in the base of the recess between a blocking position in front of the polygonal-section seat and preventing entry of a bit thereinto and a freeing position clear of the seat and permitting entry of a bit thereinto. This element can be actuated for movement between the blocking and freeing positions either manually or automatically.

摘要： A drill chuck has a chuck body rotatable about a chuck axis and having a rear end adapted to fit with a drive spindle and a front end formed with a tool recess. A plurality of jaws angularly spaced on the body about the axis and exposed in the tool recess are radially displaceable relative to the body between inner and outer positions. A tightening ring is axially fixed but rotatable about the axis on the body. Screwthread formations between the tightening ring and the jaws can move the jaws radially together and radially apart. A tightening sleeve surrounding the body and connected to the tightening ring is adapted to be gripped by hand to rotate the ring in the directions. A shield sleeve surrounds the body between the tightening sleeve and the body front end and is supported on the body for rotation thereon about the axis independently of the body and of the tightening sleeve.

摘要： A chuck body is formed with angled guides holding respective jaws. A tightening ring rotatable about the axis on the chuck body has a screwthread meshing with toothed edges of the jaws so that rotation of the ring in one direction moves the jaws axially forward and radially together and opposite rotation moves the jaws axially rearward and radially apart. A spring washer is rotatable about the axis on the body between the tightening ring and the rear jaw faces. Rearwardly directed jaw faces axially rearwardly engage and press the washer toward the tightening ring and coupling formations on the washer and ring angularly lock the washer to the ring when the washer is pressed axially rearward by the faces. Stops on the washer can engage the jaws for permitting only limited relative angular movement of the washer and jaws when the faces are pressed axially rearward against the washer.
