Abstract
The utility model discloses a nut locked three-jaw chuck, which comprises a chuck body, a wire coiling, jaws, a hand wheel, and which is provided with a locking plant of the wire coiling. The locking plant can employ multi architectures, for example, the utility model consists of a pawl matched with the wire coiling surface and a cam acted on wire coiling, both of which are connected by springs. Or the locking plant can employ a fitting pin acted on wire coiling which is connected to the thread of the chuck body. The utility model employs a self-lock plant on chuck, which is sure to keep work piece firm in refining process when operating the locking plant after work holding, which ensures the machining precision in higher degree, and safe and reliable operation.
Description
Technical field
The utility model relates to a kind of manual scroll chuck.
Background technology
In the prior art, scroll chuck can only be located workpiece in the mode that clamps, and workpiece is fixed on the chuck, but there is no locking function.The shortcoming of this chuck is: rotate at a high speed or lathe tool fast under the situation of cutting at main shaft, be difficult to guarantee that workpiece can not become flexible and influences machining accuracy, and on safety the also unavoidable potential safety hazard that flies out such as workpiece of occurring.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of with lock tight scroll chuck that overcomes above-mentioned defective.For this reason, the utility model by the following technical solutions: it comprises disk body, parcel, claw, pulls wheel, and it is provided with the locking mechanism of parcel.
Described locking mechanism can adopt multiple structure, such as, it comprises ratchet that cooperates with the parcel face and the cam that acts on ratchet, is connected by spring between ratchet and the camshaft.Perhaps, locking mechanism also can adopt the locking pin that acts on parcel that is threaded with disk body.
The utility model is owing to adopted the mechanism of self-locking locking on chuck, operable lock locking structure behind clamping work pieces can guarantee that workpiece can not become flexible in process, has guaranteed machining accuracy to a greater extent, also makes operation safe reliable simultaneously.

The specific embodiment
Embodiment 1
With reference to accompanying drawing 1,2,3,4,5,6.The utility model comprises disk body 1, parcel 7, claw 2, pulls wheel, and it is provided with the locking mechanism of parcel.Drawing reference numeral 3 is for pulling the surface in wheel operation hole.
Locking mechanism comprises ratchet 5 that cooperates with parcel face 111 and the cam 4 that acts on ratchet, is connected by spring 6 between ratchet and the camshaft 41.Disk body is provided with the hole that camshaft is installed, and ratchet turning cylinder 9 is connected with disk body.
The utility model is provided with the axial location part of cam, and is more convenient when installing and use like this, can be accurately and find cooperation position between cam and the ratchet quickly and easily.
Described axial location part is the positioning sleeve 8 between disk body and the cam of being in that is enclosed within on the camshaft, and this cover also can be to be enclosed within on the ratchet turning cylinder 9 certainly, or this axial location part also can adopt the step surface that cooperates with cam on the disk body.
The head of camshaft is provided with handle hole 42, and the camshaft handle hole is identical shaped hole with pulling the wheel operation hole.
During locking, rotating operation hole 42 makes the minimum point effect of cam be pressed on ratchet 5 afterbodys, and the head of ratchet 5 falls in the end-face helical on the parcel face 111, the locking parcel.As shown in Figure 5, claw 2 can only can not unclamp outward toward interior clamping, realizes locking function.After machining, rotating operation hole 42 makes cam 4 peaks be pressed on ratchet 5 afterbodys, and ratchet 5 front ends and parcel 7 are thrown off, and removes self-locking, and claw 2 can outwards unclamp, and unloads workpiece.
The locking pin that act on parcel 10 of locking mechanism with reference to accompanying drawing 1,7,8, present embodiment for being threaded with disk body.Claw 2 with pull wheel center fixed position, hole and bore stepped hole and its macropore is carried out tapping, locking pin 10 is loaded in the hole, behind claw 2 clamping work pieces, rotational lock pin 10, make the end face of locking pin 10 withstand parcel 17 outer ring peripheries, locking parcel 17 is when processing work, parcel can not become flexible, thereby makes workpiece be in clamped condition all the time.
The head of locking pin is provided with handle hole 12, and the locking pin handle hole is identical shaped hole with pulling the wheel operation hole.
Claims (7)
