Abstract
The utility model discloses a kind of turning clamp, described turning clamp comprises scroll chuck, 3 arc fixture blocks and several screws; Described arc fixture block lays respectively on 3 rest shoes of described scroll chuck, the periphery of described each arc fixture block is provided with protruding arc-shaped step, described arc fixture block and arc-shaped step all comprise the kidney-shaped stepped hole that 1 block body along rest shoe is arranged, and described screw is threaded with rest shoe through after kidney-shaped stepped hole.Turning clamp of the present utility model can process the product of Different Rule, therefore saves the cost of frock.
Description
Technical field
The utility model relates to machining tool clamp field, is specifically related to a kind of turning clamp.
Background technology
Fixture on existing lathe is all generally traditional Three-jaw fixture, and Three-jaw fixture is promptly fixing by workpiece to be machined, carries out turnery processing to facilitate to workpiece.Three-jaw fixture being fixedly clamped to workpiece, is mainly clamped several of workpiece by three-jaw, and that is the impetus of three-jaw is on the face of workpiece.Therefore, the workpiece that existing Three-jaw fixture is fixed some rule or applicable surface clamping and positioning, can ensure the smooth of the turning surface of workpiece.But the workpiece that an irregular or inapplicable clamping and positioning is fixing for some, its turning surface may occur crooked, can not ensure the smooth of processing cart bevel.Thus make turnery processing add very large difficulty, even can not process it with lathe, so each workpiece needs to configure corresponding frock, therefore cost is very high.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model to reduce job costs.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of turning clamp, and described turning clamp comprises scroll chuck, 3 arc fixture blocks and several screws; Described arc fixture block lays respectively on 3 rest shoes of described scroll chuck, the periphery of described each arc fixture block is provided with protruding arc-shaped step, described arc fixture block and arc-shaped step all comprise the kidney-shaped stepped hole that 1 block body along rest shoe is arranged, and described screw is threaded with rest shoe through after kidney-shaped stepped hole.
One of them arc-shaped step described is provided with a spacer and rotating shaft; It is hinged that described spacer and arc-shaped step pass through rotating shaft, and described rotating shaft is arranged on arc-shaped step and also can moves axially.
Described screw is soket head cap screw.
The end face of described screw is not higher than the end face of kidney-shaped stepped hole.
The material of described spacer is metal.
Gap is there is between described adjacent arc fixture block.
(3) beneficial effect
Turning clamp of the present utility model, by installing, 3 arc fixture blocks are set, thus erose workpiece can be fixed, without the need to making the mould arranged for single workpiece, therefore provide cost savings, and for the workpiece of different size, can be provided cost savings further by kidney-shaped stepped hole.
Accompanying drawing explanation
Fig. 1 is the normal structural representation of turning clamp of the present utility model;
The using state figure of Fig. 2 to be Fig. 1 be turning clamp of the present utility model;
Fig. 3 is the sectional view of A-A in Fig. 1;
1 be scroll chuck, 2 be arc fixture block, 3 be screw, 4 be rest shoe, 5 be arc-shaped step, 6 be kidney-shaped stepped hole, 7 be spacer, 8 for rotating shaft.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1-Figure 3, a kind of turning clamp, comprises scroll chuck 1,3 arc fixture blocks 2 and several screws 3; Described arc fixture block 2 lays respectively on 3 rest shoes 4 of described scroll chuck 1, the periphery of described each arc fixture block 2 is provided with protruding arc-shaped step 5, described arc fixture block 2 and arc-shaped step 5 all comprise the kidney-shaped stepped hole 6 that 1 block body along rest shoe 4 is arranged, and described screw 3 is threaded with rest shoe 4 through after kidney-shaped stepped hole 6.
One of them arc-shaped step 5 described is provided with a spacer 7 and rotating shaft 8; Described spacer 7 is hinged by rotating shaft 8 with arc-shaped step 5, and described rotating shaft 8 is arranged on arc-shaped step 5 and also can moves axially.
Described screw 3 is soket head cap screw.
The end face of described screw, not higher than the end face of kidney-shaped stepped hole 6, prevents location inaccurate.
The material of described spacer 7 is metal.
Gap is there is between described adjacent arc fixture block 2.
During use, first workpiece is close to the surface of arc fixture block 2, then driving rest shoe 4 to move radially by scroll chuck makes arc-shaped step 5 contact workpiece, described rotating shaft 8 drives spacer 7 to rotate spacer 7 again, described spacer 7 contacts workpiece thus is fitted in the surface of workpiece and the surface of arc fixture block 2, rest shoe 4 is driven to move radially to clamp arc-shaped step 5 finally by scroll chuck, complete installation.So the utility model can fix erose workpiece, without the need to making the mould arranged for single workpiece, therefore provide cost savings, and for the workpiece of different size, can be provided cost savings further by kidney-shaped stepped hole.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
