Abstract
The utility model provides an eccentric fixture, which comprises a chuck, three auxiliary claws and an eccentric elastic snap ring. The three auxiliary claws are fixedly connected with the chuck through bolts, the center of the eccentric elastic snap ring is coincided with the center of the chuck, and the eccentric elastic snap ring is fixedly connected with the chuck through the three auxiliary claws. The eccentric fixture has the technical advantages of compact structure, operational convenience, high machining precision, high machining efficiency, safety, reliability and the like.
Description
Technical field
The utility model belongs to lathe and uses the anchor clamps field, especially relates to a kind of eccentric fixture.
Background technology
At present, the machining eccentric work piece adopts usually presses the formula clamps workpiece that rises, through the stick control union (screwed)bonnet (UB; Compressing the core that rises causes the core that rises to shrink; With workpiece centering and clamping, but there are many defectives in actual use, on lathe, operate very inconvenient like manual clamping work pieces; The lathe of rotation might make gland loosening at a high speed, has potential safety hazard; The workpiece machining accuracy is difficult to guarantee; Production efficiency is low etc.
Summary of the invention
A kind of eccentric fixture of the utility model is to be specifically designed to the anchor clamps of producing eccentric work piece, and its purpose will solve deficiency of the prior art exactly, make its satisfy compact conformation, easy to operate, machining accuracy is high, working (machining) efficiency is high, requirement such as safe and reliable.
The technical scheme of the utility model is: a kind of eccentric fixture; Comprise chuck, three secondary pawls and eccentric snap ring; Three secondary pawls are fixedly connected with chuck through bolt, and the center of eccentric snap ring overlaps with the center of chuck, and eccentric snap ring is fixedly connected with chuck through three secondary pawls.
The axis of described three secondary pawls is mutually 120 °.
Described eccentric snap ring is provided with opening.
On the described chuck eccentric block is housed.
Advantage and the good effect that the utlity model has are: adopt technique scheme, realized compact conformation, easy to operate, machining accuracy is high, working (machining) efficiency is high, technical characterstic such as safe and reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model
Among the figure:
1, chuck 2, secondary pawl 3, eccentric snap ring
4, eccentric block
The specific embodiment
As shown in Figure 1; A kind of eccentric fixture of the utility model; Comprise chuck 1, three secondary pawls 2 and eccentric snap rings 3; Three secondary pawls 2 are fixedly connected with chuck 1 through bolt, and the center of eccentric snap ring 3 overlaps with the center of chuck 1, and eccentric snap ring 3 is fixedly connected with chuck 1 through three secondary pawls 2.
The axis of described three secondary pawls 2 is mutually 120 °, has guaranteed the centering precision of eccentric snap ring 3, has satisfied the production needs.
Described eccentric snap ring 3 is provided with opening, makes eccentric snap ring 3 have certain elasticity.
On the described chuck 1 eccentric block 4 is housed, has guaranteed the stationarity of processing, improved the security of processing.
The course of work of this instance: the chuck 1 of eccentric fixture is connected with the rotary main shaft of lathe through bolt; Eccentric snap ring 3 keeps concentric consistent with the workpiece machining hole center and chuck 1 centre of gyration; And workpiece precisely felt relieved clamp with firm, satisfy the requirement of eccentric processing.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
