Description
The technical field is as follows:
the utility model belongs to the technical field of the chemical industry equipment technique and specifically relates to an anchor clamps frock for processing thin wall ring part that says so.
Background art:
in machining, in order to ensure the machining precision and the machining quality of parts, the parts are fixed on a machine tool workbench through a clamp. For thin-wall ring parts with the diameter less than 500mm, if end face machining and grooving machining are required to be carried out on the thin-wall ring parts, a common horizontal lathe can be generally adopted, the thin-wall ring parts are clamped on a main shaft of the horizontal lathe by connecting claws, and meanwhile, a plurality of auxiliary supports are required to be supported at the bottom of the thin-wall ring parts to adapt to the end face machining. In addition, the outer circle of the thin-wall circular ring part is clamped by the connecting claw, the clamping claw of the connecting claw is in point contact with the thin-wall circular ring part, the force application point is uneven, the outer circle of the thin-wall circular ring part is easily damaged, the clamping deformation is easily generated, and therefore the processing quality of the part is reduced.
For clamping of thin-wall circular ring parts with different sizes, when the sizes are greatly different, connecting claws with corresponding specifications are often required to be replaced so as to clamp the parts well, and therefore the parts are troublesome to replace and the replacement efficiency is low.
The utility model has the following contents:
for solving the problem, overcome the not enough of prior art, the utility model provides a quick change dress, press from both sides tight and the location, can not cause the thin wall ring part to warp, improve machining efficiency's the anchor clamps frock for processing thin wall ring part.
In order to achieve the purpose, the utility model provides a fixture tool for processing thin-wall circular ring parts, which comprises a three-jaw chuck and three connecting jaws detachably arranged on the three-jaw chuck, wherein the three connecting jaws are fixedly provided with clamping plates, and the clamping plates are arranged into an arc-shaped structure;
every two of the three splints are connected end to form a complete annular structure.
Furthermore, the clamp also comprises a thin-wall ring part which is detachably clamped in the annular structure formed by the three clamping plates.
Furthermore, a guide block is further installed on the connecting claw, three guide grooves are formed in the three-jaw chuck, and the guide block is matched with the guide grooves.
Furthermore, the three connecting claws are arranged in a matrix position with a phase difference of 120 degrees between every two connecting claws.
Further, still include the bolt, splint pass through two bolts and connection claw fixed connection.
Furthermore, the inner side of the clamping plate is provided with a clamping groove for clamping the thin-wall circular ring part.
The utility model has the advantages that:
the utility model provides an anchor clamps frock for processing thin wall ring part has quick reloading, presss from both sides tightly and fixes a position, can not cause thin wall ring part to warp, improves machining efficiency's advantage, constitutes complete ring structure through three identical splint to wrap up the centre gripping completely with the excircle of thin wall ring part, make each position atress of excircle identical, thereby guaranteed that thin wall ring part can not take place to warp.
In the actual machining process of the numerical control machine tool, the annular clamp structure is more suitable for rotating on a machining center or the machine tool, and the rotating process is more stable.
The clamp plate with the corresponding diameter can be selected according to thin-wall circular ring parts with different sizes, the three-jaw chuck does not need to be replaced, the workpiece replacing operation is simple, and the replacing efficiency is high.
Description of the drawings:
FIG. 1 is a schematic structural diagram of the present invention;
FIG. 2 is an enlarged view of the clamp plate of the present invention;
FIG. 3 is a schematic side view of the present invention;
in the drawings: 1. the clamping device comprises a clamping plate, 2, a connecting claw, 3, a guide block, 4, a bolt, 5, a three-jaw chuck, 11 and a clamping groove.
The specific implementation mode is as follows:
for making the purpose, technical scheme and advantage of the utility model implementation clearer, will combine below the utility model discloses an attached 1~ attached 3 of the utility model is right the utility model discloses carry out more detailed description.
The utility model provides an anchor clamps frock for processing thin wall ring part, including three-jaw chuck 5, its characterized in that: the three-jaw chuck is characterized by further comprising three connecting jaws 2 which are detachably arranged on the three-jaw chuck 5, wherein clamping plates 1 are fixedly arranged on the three connecting jaws 2, and the clamping plates 1 are of arc-shaped structures; every two of the three splints 1 are connected end to form a complete annular structure; the clamp also comprises a thin-wall ring part which is detachably clamped in an annular structure formed by the three clamping plates 1; the connecting claw 2 is also provided with a guide block 3, the three-jaw chuck 5 is provided with three guide grooves, and the guide block 3 is matched with the guide grooves; the three connecting claws 2 are arranged in a matrix position with a phase difference of 120 degrees in pairs; the clamping plate 1 is fixedly connected with the connecting claw 2 through two bolts 4; the inner side of the clamping plate 1 is provided with a clamping groove 11 for clamping a thin-wall circular ring part.
The utility model discloses a one of them embodiment as follows:
the three-jaw chuck 5 is connected with the connecting jaw 2 through a guide groove and a guide block 3, the guide block 3 can slide in the guide groove and then is fixed through a bolt 4.
