Abstract
The utility model discloses an inner bore fixture of a grinding machine for processing a power steering screw. The inner bore fixture comprises a grinder spindle in which a positioning push rod housing is arranged, an elastic positioning tip is arranged in the positioning push rod housing and is sleeved with a spring, the side wall of the grinder spindle is connected with a transition flange through a screw, and the transition flange is connected with a clamp body connected with an elastic membrane chuck; a plurality of adjusting nuts are uniformly distributed on the peripheral wall of the elastic membrane chuck, a steering screw is sleeved in the positioning push rod bushing, the large end of the steering screw is adjusted and fixed through a plurality of adjusting nuts, and the small end of the steering screw is propped on the elastic positioning tip. The inner bore fixture provided by the utility model has the advantages of guaranteeing the work-piece positioning precision and being convenient to operate.
Description
Technical field
The utility model relates to a kind of inner hole grinding machine fixture for processing dynamics steering screw.
Background technology
While generally carrying out electronic-controlled power steering screw rod now, all need to adopt fixture and grinding machine spindle to fix, fixture adopts the circular hole of fixed dimension, the structure that side adds screw fastening, but this fixture operation inconvenience, part handling difficulty, and in process, be easy to have an accident, endoporus and the outer circles error of mill processing are simultaneously large, even reach 0.12mm, cause the decline of overall performance.
Summary of the invention
The purpose of this utility model is in order to overcome above deficiency, and a kind of workpiece positioning precision, easy to operate inner hole grinding machine fixture for processing dynamics steering screw of ensureing is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of inner hole grinding machine fixture for processing dynamics steering screw, comprise grinding machine spindle, in grinding machine spindle, be provided with localization handspike cover, in localization handspike cover, be provided with elasticity locating centre, on elasticity locating centre, cover has spring, the sidewall of grinding machine spindle has been connected by screw counter flange, counter flange is connected with clamp body, clamp body is connected with elastic membrane chuck, on the outer circle wall of elastic membrane chuck, be evenly distributed with multiple adjusting nuts, in localization handspike cover, be provided with steering screw, the large end of steering screw is fixed by multiple adjusting nut adjustment, the small end of steering screw withstands on elasticity locating centre.
The utility model compared with prior art has the following advantages: operate that extremely fast and easy, positioning precision are very high, the deformation power that can ensure in 0.02, Workpiece clamping adopts fixture, do not need extra power, the not extra consumed energy of process, has environmental protection characteristic.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model;
Number in the figure: 1-grinding machine spindle, 2-localization handspike cover, 3-elasticity locating centre, 4-counter flange, 5-clamp body, 6-elastic membrane chuck, 7-adjusting nut, 8-steering screw, 9-spring.
detailed description of the invention:
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment only, for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1 shows the detailed description of the invention of a kind of inner hole grinding machine fixture for processing dynamics steering screw of the utility model, comprise grinding machine spindle 1, in grinding machine spindle 1, be provided with localization handspike cover 2, in localization handspike cover 2, be provided with elasticity locating centre 3, on elasticity locating centre 3, cover has spring 9, the sidewall of grinding machine spindle 1 has been connected by screw counter flange 4, counter flange 4 is connected with clamp body 5, clamp body 5 is connected with elastic membrane chuck 6, on the outer circle wall of elastic membrane chuck 6, be evenly distributed with multiple adjusting nuts 7, in localization handspike cover 2, be provided with steering screw 8, the large end of steering screw 8 is adjusted fixing by multiple adjusting nuts 7, the small end of steering screw 8 withstands on elasticity locating centre 3.
Fixture for grinding machine described in the utility model, by utilizing the stressed generation strain of metal parts, can automatically recover the physical characteristic of reset condition after external force disappears, and deformation power is for the clamping to workpiece, and the uniformity of deformation ensures the positioning precision of workpiece.Operation principle is as follows: 1, Fixture assembly, to machine tool chief axis, carries out autogenous grinding to clamp position, is milled to interior hole dimension less by 0.05 than excircle of workpiece; 2, push away flexible sheet with pushing rod sleeve, diaphragm applied force distortion, opens the clamping position being fixed thereon; 3, workpiece is pushed and clamps position along hole, the top meeting arranging in fixture is by righting inside workpiece; 4, pushing rod sleeve is removed, diaphragm deformation recovers gradually, clamps position and dwindles gradually, until by Workpiece clamping.5, mill inner hole of workpiece; 6, push away diaphragm with pushing rod sleeve, diaphragm deformation, clamps position and opens, and top spring ejection point reach below, pushes away fixture by workpiece, and workpiece is taken off, and refills next workpiece.Fixture for grinding machine described in the utility model operates that extremely fast and easy, positioning precision are very high, and the deformation power that can ensure in 0.02, Workpiece clamping adopts fixture, does not need extra power, and the extra consumed energy of process, has environmental protection characteristic.
