Abstract
The utility model relates to a multipurpose spring grip which is suitable for the machine building. On the basis of the quickly detachable multi-purpose grip of the patent application number 90219982X, the grip main body of the quickly detachable multi-purpose grip is drilled with a small hole perpendicular to each waist shape hole wall. A straight flute 2 is formed between the connected line of the two small holes and a conical surface. The corresponding position of a slide block is drilled with small holes, and the slide block is connected with the grip main body at the proper position by a spring wire. The multipurpose spring grip reserves all advantages of the quickly detachable multi-purpose grip, and is applied to the automatic feed machine.
Description
The utility model is a kind of collet of using that is applied to machinery manufacturing industry more.
The chucks of using of loading and unloading fast of selecting utility application 90219982X for use as correlation technique of the present utility model more.
Fig. 1 is the many profiles with chuck of loading and unloading fast;
Fig. 2 is the A-A cutaway view of Fig. 1.
This chuck is installed on the lathe rotating shaft, and its primary structure is; Chuck body one end is a cylinder, and two keyways of 180 ° of being separated by are arranged on the cylinder outer surface, and the center has and is used for screwing in the internal thread of handling leading screw; The other end is a cone, there is a hole at the cone center, evenly having mounting hole axial arranged more than two on the cone dignity, the mid-slide block of each mounting hole, the end face of slide block cooperates with conical bore on the rotating shaft, and the bottom surface of slide block contacts with workpiece, according to different purposes, the bottom surface of slide block makes the face of cylinder, taper seat, plane or inclined-plane, is used for clamping cylinder, cone, prism or pyramid workpiece respectively.When one group of slide block height is different, be used for eccentric clamping.
During work, by handling leading screw chuck is moved axially in rotating shaft, the conical bore on the rotating shaft forces slide block to be assembled to the center, thereby reaches the purpose of clamping work pieces.When chuck moves on to maximal work position, the right, clamp maximum workpiece, when moving on to maximal work position, the left side, clamp minimum workpiece.A this chuck can replace the old chuck of tens different sizes; The wearing and tearing back only needs to change slide block, and the chuck body can use for a long time, has saved labor and materials widely, has improved production efficiency.
Though how this quick loading and unloading have with chuck and have many advantages, but there is significant deficiency again simultaneously: promptly when needs loosen workpiece, slide block outwards slippage automatically, not only when chuck is installed in the centre bore for level but also is not had workpiece, being in the above slide block of central plane falls because of the gravity effect, centre bore might be blocked, thereby can not be applied on the automatic feed charging lathe.
The purpose of this utility model is to increase a part on chuck in that above-mentioned quick loading and unloading are many, make it become a kind of collet of using more, it has kept whole advantages that chuck is used in quick loading and unloading more, make when needs loosen work slide block outwards slippage automatically again, the blocks central aperture that can not fall, thus can be applied on the automatic feed lathe.
The utility model is many to be achieved like this with collet, promptly uses on the chuck original structure in above-mentioned quick loading and unloading more, chuck body and slide block is run through with a spring steel wire in the appropriate location.
Fig. 3 is the profile that the utility model is used collet more;
Fig. 4 is the A-A cutaway view of Fig. 3.
Below in conjunction with accompanying drawing how the utility model is described in detail with the chuck difference with loading and unloading are many fast with collet:
How the utility model is in that loading and unloading are many with on the chuck body appropriate location of chuck fast with collet, respectively bores an aperture perpendicular to each mounting hole wall; Between two apertures and the taper seat handing-over line, make straight trough 2; The slide block relevant position also is drilled with aperture; A spring steel wire 3 runs through chuck body and slide block.Under the effect of spring steel wire 3, slide block outwards opens all the time, and open distance makes when chuck is in maximal work position, the right, can freely insert a maximum workpiece in the centre bore.
During work, when by handling leading screw chuck being moved to the left, slide block is subjected on the rotating shaft compressing of conical bore to assemble clamping work to the center.Otherwise under the effect that plays steel wire 3, slide block outwards opens, and loosens work, and blocks central aperture can not fall.
The multiplex collet of the utility model is compared with the multiplex chuck of quick loading and unloading has following advantage: multiplex collet has the characteristic of collet, can just be used for the automatic feed lathe.
Claims (1)
- A kind ofly many use collet, chuck body one end is a cylinder, and two keyways of 180 ° of being separated by are arranged on the cylinder outer surface, and there is the internal thread that is used for screwing in the manipulation leading screw at the center; The other end is a cone, there is a hole at the cone center, and cone dignity upper edge circumference evenly has mounting hole axial arranged more than two, the mid-slide block of each mounting hole, close joining of conical bore on plain line in the center of slide block end face and the lathe rotating shaft, the bottom surface of slide block contacts with workpiece; It is characterized in that apart from cylinder one end appropriate location, respectively bore an aperture 1 perpendicular to each mounting hole wall, make straight trough 2 between two apertures and the taper seat handing-over line, also occupy aperture on the slide block relevant position, chuck body and slide block are run through with a spring steel wire 3.
