Abstract
The utility model relates to an automatic clamping finish turning clamp used during gear machining, which comprises a clamp body, a roller and two limiting blocks. The two limiting blocks are fixed on the clamp body through screws; a sliding groove is formed between the two limiting blocks on the clamp body; and the roller is installed in the sliding groove of the clamp body and can laterally move in the sliding groove. The automatic clamping finish turning clamp has the advantages that the structure is novel, positioning is reliable, clamping is rapid, and work pieces are convenient to clamp.
Description
Technical field
The utility model relates to used lathe finish fixture in the Gear Processing.
Background technology
In the processing of gear teeth base; Press the GB10095-88 standard; 7-8 class precision bore precision is pressed IT7 processing; The general lathe finish fixture that adopts of this process has three kinds of interference fit mandrel, tapering mandrel and spring housing mandrels, and the deficiency that preceding two kinds of mandrels exist is the ruined situation of tooth base bore area in use often to occur, and workpiece loading and unloading is time-consuming; The deficiency that the spring housing mandrel exists is because spring housing is a thin-wall part; The manufacturing of spring housing is again a difficult point; Tooth base end face run-out after often occurring in actual the use processing does not reach the situation of requirement; And since the tapering half-angle of spring housing less than from the locking angle, processing back tooth base is difficult to disassemble from anchor clamps.
Summary of the invention
The goal of the invention of the utility model provides a kind of novel structure in order to solve the deficiency that existing lathe finish fixture exists, and the location is reliable, clamps rapid clamping workpiece and clamps lathe finish fixture easily automatically.
For realizing the foregoing invention purpose, the technical scheme below the utility model has adopted:
Automatically clamp lathe finish fixture; Comprise chuck body, roller and two limited blocks; Two limited blocks are fixed on the chuck body through screw, are chute between two limited blocks on the chuck body, and roller is installed in the chute place of chuck body and can in chute, laterally moves.
Adopted the automatic clamping lathe finish fixture of technique scheme; Workpiece is enclosed within on the chuck body during use; Because the action of inertia workpiece has slight relatively rotating with chuck body, the interior roller of the chute between two limited blocks just wedge clamped workpiece between workpiece and chuck body automatically, after workpiece machines when lathe started; Change along the lathe direction of rotation workpiece that workpiece promptly unclamps, can unload workpiece.The advantage that should clamp lathe finish fixture automatically is a novel structure, and the location is reliable, clamps rapidly, and clamping workpiece is convenient.
Description of drawings
Fig. 1: the example structure sketch map of the utility model.
Fig. 2: the cross-sectional view of the embodiment of the utility model.
The specific embodiment
The utility model is done with Fig. 2 below in conjunction with accompanying drawing 1 and to be further described.
Automatic clamping lathe finish fixture as depicted in figs. 1 and 2 is made up of chuck body 1, roller 3 and two limited blocks 4.Two limited blocks 4 are fixed on the chuck body 1 through screw, are chute 5 between two limited blocks 4 on the chuck body 1, and roller 3 is installed in chute 5 places of chuck body 1 and can in chute 5, laterally moves.
During use, workpiece 2 is located on chuck body 1 cylindrical through endoporus, and roller 3 wedges in the chute 5 between two limited blocks 4 clamp workpiece 2 between workpiece and chuck body 1 automatically; Specifically be after workpiece 2 is enclosed within on chuck body 1 cylindrical; Start lathe because action of inertia workpiece 2 has slight relatively rotating with chuck body 1, roller 3 is that wedge is between workpiece 2 and chuck body 1, when angle of wedge A belongs to the self-locking angular region between 4 °-7 ° the time; Under the cutting force effect; Workpiece 2 will further clamp, and cutting force is big more, and clamping force is big more.After workpiece 2 machined, as long as catch workpiece 2 to change along the lathe direction of rotation, workpiece 2 promptly unclamped, and can unload workpiece 2 easily.
