Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, a machine tool accessory collet chuck which is firmly installed and is convenient to replace comprises a fixing rod 1 and a collet cap 2, a threaded rod 3 is fixedly connected to the bottom of the fixing rod 1, a first screw hole 4 is formed in the surface of the fixing rod 1, at least six screw holes 4 are formed in the surface of the fixing rod 1, a first screw 5 is in threaded connection with the inside of the first screw hole 4, a first fixing block 6 is fixedly connected to the top of the fixing rod 1, a second fixing block 7 is movably connected to the top of the first fixing block 6, the top of the first fixing block 6 is the same as the bottom of the second fixing block 7 in size, so that the first fixing block and the second fixing block are convenient to connect, a clamping plate 8 is fixedly connected to the top of the second fixing block 7, at least six clamping plates 8 are arranged, a blank can be clamped more, three 11 screw holes have been seted up at the top of fixed block 6, six are no less than to the quantity of two 10 screw holes and three 11 screw holes, and both longitudinal symmetry, make the fastening more that fixed block 6 and fixed block two 7 can be connected, the inside threaded connection of three 11 screw holes has two 12 screws, two 10 screw holes and three 11 sizes of screw holes are the same, and both pass through two 12 screw thread connections of screw, round hole two 13 has been seted up to the inside of dead lever 1, round hole one 9 and two 13 sizes of round hole are the same, make things convenient for the bottom of blank to enter into round hole two 13 inside, round hole three 14 has been seted up to chuck cap 2's inside, the left side diameter of round hole three 14 is greater than the diameter of fixed block two 7, the right side diameter of round hole three 14 is less than the diameter of fixed block two 7, and the inside helicitic texture that is in the left side of round hole three 14.

The working principle is that firstly the threaded rod 3 is fixed on a machine tool, then the clamp head cap 2 is clamped on the clamp plate 8, then the blank is inserted into the first round hole 9, at the moment, the clamp head cap 2 is rotated, because the diameter of the left side of the third round hole 14 is larger than that of the second fixed block 7, the diameter of the right side of the third round hole 14 is smaller than that of the second fixed block 7, the inner part of the left side of the third round hole 14 is in a threaded structure and is matched with the surface threads of the second fixed block 7, and because the third round hole 14 is arranged in the clamp head cap 2, the clamp head cap 2 is in threaded connection with the second fixed block 7, and along with the increase of the contact area between the clamp head cap 2 and the second fixed block 7, the third round hole 14 can fasten the clamp plate 8 at the top of the second fixed block 7, so that the blank is fastened, and because the first round hole 9 and the second round hole 13 are, the first round hole 9 is formed in the second fixing block 7, the second round hole 13 is formed in the fixing rod 1, the first screw hole 4 is formed in the surface of the fixing rod 1, and the first screw 5 is connected to the inner thread of the first screw hole 4 in a threaded mode, so that the first screw 5 is rotated, the first screw 5 is clamped on the blank, the blank can be further fixed, and the effects that the spring chuck is firm to mount and is not prone to offset when the blank is assembled are achieved. When collet chuck used a period of time mouthful, splint 8 was worn and torn to make the fastening firm inadequately, collet chuck's head can be changed this moment, because two 10 and three 11 big or small the same in screw hole, and both pass through two 12 threaded connection of screw, so rotate two 12 screws, can make two 10 and three 11 separations in screw hole of screw hole, again because three 11 setups in the top of fixed block 6 in screw hole, two 10 setups in the bottom of fixed block two 7 in screw hole, so fixed block one 6 and two 7 separations of fixed block this moment, thereby reached and changed collet chuck head, effect of cost is reduced. And the head of the spring chuck with different sizes is replaced, so that the effect of fixing different blanks can be achieved, and the effect of further reducing the cost can be achieved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
