Description

Anti-collision drill chuck

Technical Field

The utility model relates to a drill chuck technical field specifically is an anticollision drill chuck.

Background

The drill chuck consists of a drill clamping sleeve, an elastic shifting ring, a connecting block and a rear cover. The drill chuck is mainly used for household direct current and alternating current electric drills. The locking device has the greatest advantage that the locking device is easy to lock, and can be used only by holding the front sleeve and the rear sleeve of the chuck and screwing. The drill chuck is structurally divided into two categories, namely a wrench type and a hand-tightening type. The wrench type drill chuck needs to be screwed by a wrench wheel and is mainly used in the machine tool industry, such as bench drills and electric hand drills. The hand-held drill chuck is mainly used on an electric hand drill. The spanner drill chuck is screwed by the spanner wheel which is a bevel gear with an elongated force arm, so that the spanner drill chuck can play a role in increasing torque and conveying people in the screwing process. The three main parameters of the drill chuck are precision, clamping force and clamping range. The precision is used for controlling the jumping amount of the clamping handle type tool so as to ensure the precision of the processing hole. The clamping force is used for ensuring that the clamped handle tool does not slip and preventing the handle tool from failing to work due to the slip. Typically the accuracy of the chuck used on bench drills is somewhat higher and the accuracy of the chuck used on hand drills is relatively lower. The grip range is used to control the minimum and maximum diameters of the collet gripping tool to meet the operating requirements. Under normal conditions, the maximum clamping range is only about 0.3mm larger than the specification of the chuck.

The existing drill chuck has the defects that firstly, burrs are easily generated during drilling to influence the appearance, annular inclined holes are easily impacted to be damaged by external objects, burrs can be inverted after orifices are impacted, clamping jaws are unstable after being inverted to influence the quality of workpieces, and secondly, the fixing clamping effect is poor and the appearance aesthetic feeling is poor.
