Abstract
A quick-replacement fixture comprises a fixture body, a fixture rod, steel balls and a locking sleeve. An installation hole is formed in one end of the fixture body, and two ball sockets are symmetrically arranged on the outer wall of the installation hole of the fixture body. The fixture rod is arranged in the installation hole of the fixture body in a sleeved mode, and locking grooves are formed in the fixture rod. The fixture body is sleeved with the locking sleeve. The inner surface of the locking sleeve is a conical surface at a certain inclination angle, the steel balls are installed in the two ball sockets respectively and clamped in the locking grooves of the fixture rod, and the inner surface of the locking sleeve presses the steel balls. The quick-replacement fixture achieves quick and easy replacement of tools, effectively relieves labor intensity and improves working efficiency.
Description
Technical field
The present invention relates to a kind of clamping tool for machine work, the magic chuck particularly a kind of drilling machine used.
Background technology
In the cutter clamping mode of drilling machine, generally all adopt the structure that drill press spindle internal taper hole matches with the male cone (strobilus masculinus) of handle of a knife (or spacer shell).When changing cutter, need first drift to be inserted in the removal hole on drill press spindle, then the drift that hits with a hammer can pull down cutter.When processing one has the part in plurality of specifications hole, changing cutter continually will with whole process, and the mode that the drift that makes to hit with a hammer changes cutter not only wastes time and energy but also produce noise.
Summary of the invention
The invention solves the problem that cutter inconvenience changed by drilling machine, provide one and can change cutter fast, easily, effectively reduce labor intensity, the cutting tool of fast exchanging of increasing work efficiency.
For solving the problems of the technologies described above, present invention employs a kind of magic chuck, comprise chuck body, clamp rod, steel ball and lock sleeve, described chuck body one end is provided with installing hole, the outer wall of described chuck body installing hole is provided with two symmetrical ball-and-sockets, described clamp rod is sleeved in the installing hole of chuck body, clamp rod is provided with locking slot, described lock sleeve is enclosed within chuck body, the inner surface of lock sleeve is the taper seat with certain inclination angle, described steel ball is arranged in two ball-and-sockets respectively, steel ball is stuck in the locking slot of clamp rod, lock sleeve inner surface is pressed on steel ball.
Described chuck body is provided with cannelure, in cannelure, check ring is installed.
The present invention in use only need change the clamp rod assembly assembled, the i.e. cutter of replaceable dimension, by the frame mode that taper hole coordinates, there is obvious advantage with cutter compared to main shaft on drilling machine, especially the specification for hole is many, the parts frequently changing cutter are needed in process, use this magic chuck greatly can improve the speed of tool changing, alleviate labour intensity during tool changing, improve operating efficiency.

In figure: 1, drill press spindle; 2, chuck body; 3, check ring; 4, lock sleeve; 5, steel ball; 6, clamp rod; 7, installing hole; 8, cutter; 9, cannelure; 10, ball-and-socket; 11, locking slot.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As illustrated in fig. 1 and 2, for a kind of magic chuck, comprise chuck body 2, clamp rod 6, steel ball 5 and lock sleeve 4, chuck body 2 one end is provided with installing hole 7, the outer wall of chuck body installing hole 7 is provided with two symmetrical ball-and-sockets 10, clamp rod 6 is sleeved in the installing hole 7 of chuck body 2, clamp rod 6 is provided with locking slot 11, lock sleeve 4 is enclosed within chuck body 2, the inner surface of lock sleeve 4 is the taper seat with certain inclination angle, steel ball 5 is arranged in two ball-and-sockets 10 respectively, steel ball 5 is stuck in the locking slot 11 of clamp rod 6, lock sleeve 4 inner surface is pressed on steel ball 5.Chuck body 2 is provided with cannelure 9, check ring 3 is installed in cannelure 9.
Lock sleeve 4 in tandem of the chuck body 2 be contained in drill press spindle 1 is upwards pushed into the spacing place of check ring 3, and at this moment two steel balls 5 outwards will roll out certain distance from the ball-and-socket of two chuck body 2 10 li, but can not fall down from chuck body 2.Again clamp rod 6 upper end of good cutter 8 in tandem is inserted in the installing hole 7 of chuck body 2, by lock sleeve 4 light pressure downwards while rotary clamp bar 6, make two steel balls 5 be pressed into two ball-and-sockets 10 li, also closely cooperate with the locking slot 11 on clamp rod 6 simultaneously.At this moment, lock sleeve 4 will make two steel balls 5 with surely living clamp rod 6 by deadweight.When changing clamp rod 6, buttress clamp rod 6 on the other hand, on the other hand lock sleeve 4 is upwards pushed into the spacing place of check ring 3, at this moment steel ball 5 will unclamp clamp rod 6, clamp rod 6 automatically will fall down by deadweight from the installing hole 7 of chuck body 2, and then is loaded in chuck body 2 by another clamp rod assembly.
