Description

A kind of floating clamp

[technical field]

The utility model relates to machined field, especially relates to that a kind of circularity is had relatively high expectations and the floating clamp of thin-walled drum product for processing.

[background technology]

Known, in the time of processing equipment part, normally utilize the fixture that is arranged on corresponding lathe to fix part to be processed, thereby reach bowlder outside processing parts endoporus and plane, ensure the object of the diameter of part circularity processing with this, but, in practical operation, in the time that the processing thin-walled part of needs or circularity require high part, reach circularity requirement because existing stiff points contact fixture is more difficult, thereby it is also difficult to effectively ensure part circularity, be embodied in: under the clamping force effect of rigidity fixture, the thin-walled parts that circularity is had relatively high expectations very easily produces distortion, this not only easily makes the part end face after processing occur irregular deformation, have influence on the precision of processing, and the difficult dimensional tolerance that ensures part, this not only has influence on mach flatness, and can cause follow-up assembling to occur quality problems, as causing fitting surface, face deformation can not evenly coincide, hole site deviation, position degree deviation causes that Assembly of the parts is not in place maybe cannot be assembled etc., in addition, existing fixture usually also will ensure in conjunction with more dispersing technology the circularity of part in application, but circularity not only can not be effectively guaranteed in such operation, but also can, because using too much lathe and operating personnel to cause the increase of manufacturing cost, cause burden economically finally to production and processing side.

[summary of the invention]

In order to overcome the deficiency in background technology, the utility model discloses a kind of floating clamp of flatness and the circularity that can effectively improve the thin-walled parts processing.

For achieving the above object, the utility model adopts following technical scheme:

A kind of floating clamp, described fixture comprises three-jaw and three groups of arc chuck structures that are symmetric, and the corresponding standard round that forms of the intrados of three groups of chuck structures; Every group of described chuck structure all comprises a clamp body and two cramping bodies, and the intrados middle part of each clamp body is equipped with convex, and the both sides of convex respectively correspondence are provided with a cramping body, and the intrados of two cramping bodies and the same circle of the intrados of convex; Described cramping body both sides are respectively by support screw connection corresponding to clamp body, and the center of corresponding each cramping body of clamp body is equipped with the jackscrew of a conflict cramping body; The extrados middle part of three described clamp bodies is fixedly connected with a rotating shaft respectively, and in three-jaw, a side of each claw is equipped with the axis hole for connecting with corresponding rotating shaft simultaneously.

Further, the intrados of described cramping body has three place's boss uniformly.

Further, described jackscrew is round end screw rod.

Further, described fixture is provided with the symmetrical arc chuck structure of many groups and the claw of respective numbers.

Owing to adopting technical scheme as above, the utlity model has following beneficial effect:

Floating clamp described in the utility model is simple in structure, is easy to manufacture convenient operation; Described fixture not only can effectively reduce operating procedure in the time of application, time processing goes out to meet the part circularity of plane high request, but also can effectively improve element precision and the working (machining) efficiency of processing, the corresponding effective part scope that can be applicable that expanded also simultaneously.

[detailed description of the invention]

Can explain in more detail the present invention by the following examples, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples:

Floating clamp described in 1～2 by reference to the accompanying drawings, described fixture comprises three groups of arc chuck structures that are symmetric and by being distributed on moving radially of three movable jaws on three groups of chuck structures, finally drives chuck structure that part to be processed is clamped and the three-jaw 1 of location; The corresponding standard round that forms of the intrados of three groups of described chuck structures by the corresponding cylindricals that are clamped in part to be processed that coincide of these three groups of chucks, thereby can effectively keep the circularity of part to be processed in process; Every group of described chuck structure all comprises a clamp body 2 and two cramping bodies 3, the intrados middle part of each clamp body 2 is equipped with convex 4, the both sides of convex 4 respectively correspondence are provided with a cramping body 3, and the intrados of the intrados of two cramping bodies 3 and convex 4 is with circle, thereby the clamping part to be processed that the intrados that can utilize six cramping bodies 3 in three groups of chucks is identical, or utilize the intrados of six cramping bodies 3 and three convexes 4 jointly to clamp part to be processed;

Described cramping body 3 both sides are respectively by penetrating support screw 5 connection corresponding to clamp body 2 of clamp body 2, and the center of clamp body 2 corresponding each cramping body 3 is equipped with the round end screw rod jackscrew 6 of a conflict cramping body 3, be that cramping body 3 is arranged on the relevant position on clamp body 2 by support screw 5, thereby can clamp uniformly part outer, can also regulate the circular runout of cramping body 3 in the time clamping part by jackscrew 6 simultaneously; For further ensureing the circularity of part to be processed, can set out uniformly three place's boss 8 at the intrados of cramping body 3, clamp the cylindrical of part to be processed with a kind of multiple spot form of even cloth, thereby reach the stressed more uniform and stable object of cylindrical that makes part to be processed; For ease of operation, be beneficial to the cylindrical of clamping part to be processed, the extrados middle part of described three clamp bodies 2 is fixedly connected with a rotating shaft 7 respectively, in three-jaw 1, a side of each claw is equipped with the axis hole 9 for connecting with corresponding rotating shaft 7 simultaneously, can control the mobile accuracy that drives three-jaw 1 and clamp body 2 by rotating shaft 7, thereby reach the object of effective raising machining accuracy; As required, if when the diameter of part to be processed is larger, can also adopt the claw of the symmetrical arc chuck structure of many groups and respective amount to form described fixture, thereby make described fixture can adapt to the part processing that cylindrical is larger.

The utility model does not describe part in detail for prior art, therefore the utility model is not described in detail.
