Clip-on chuck

Abstract

The invention relates to the technical field of machine tool fixtures, in particular to a holder type chuck. According to the holder type chuck, at least two T-shaped grooves in the horizontal direction are formed in a chuck body; a shaft hole is formed in the center of the chuck body; clamping jaws include the bottom jaws and the upper jaws, wherein the bottom jaws and the upper jaws are fixedly arranged. Each bottom jaw comprises a bottom jaw plate and a side plate. The included angle between each bottom jaw plate and the corresponding side plate is smaller than 90 degrees. Bottom jaw slide blocks are arranged on the bottom jaw plates. At least two obliquely-formed oblique grooves matched with the side plates in shape are formed in a wedge-shaped sleeve. The included angle between the oblique grooves and the axis of the oblique sleeve is equal to the included angle between the bottom jaw plates and the side plates. The clamping jaws are arranged in the T-shaped grooves through the bottom jaw slide blocks in a sliding manner. The side plates are arranged in the oblique grooves of the wedge-shaped sleeve. A pull rod is fixedly arranged on the wedge-shaped sleeve. The holder type chuck is provided, the pull rod can penetrate workpieces needing to be machined, then, the clamping jaws are driven to move towards the center of the chuck by moving the pull rod downwards, and clamping of the machined workpieces is completed; and because the total length of the holder type chuck is small, the function of conducting machining on two sides at the same time can be achieved, and efficiency is high.

Description

technical field [0001] The invention relates to the technical field of machine tool fixtures, in particular to a clamp-type chuck. Background technique [0002] The headstock of the existing chuck type chuck is too long to realize double-sided simultaneous processing, and the efficiency is low. The overall length of the chuck is short, which can realize double-sided simultaneous processing of shaft parts in one clamping, which greatly improves production efficiency. It has many advantages such as light body, convenient installation, small space occupation, and wide application range. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problem that the original spindle box is too long to realize double-sided simultaneous processing, and the efficiency is low, the present invention provides a chuck type chuck, which can hold the workpiece to be processed Pass through the pull rod, and then move the pull ro...
