Abstract
A three-turn bent axle processing clamp relates to a bent axle processing clamp, in particular to the improvement of a three-turn bent axle processing clamp structure. The three-turn bent axle processing clamp has the advantages that the structure is simple, the processing precision of an eccentric shaft neck of a three-turn bent axle is improved, and the centering time is shortened. The three-turn bent axle processing clamp comprises a base, wherein an upper gland is arranged on the base; a circular hole is formed between the upper gland and the base. The three-turn bent axle processing clamp is characterized in that a clamp body is arranged in the circular hole; the outer contour of the clamp body is a circle which is matched with the circular hole; an orthohexagonal hole is formed in the clamp body; the center of the orthohexagonal hole is overlapped with the circle center of the outer contour of the clamp body.
Description
Technical field
The utility model relates to a kind of Crankshaft Machining jig, and specifically, the utility model relates to a kind of improvement of three-throw crankshaft machining fixture structure.
Background technology
Machining crankshafts rotor journal on whirlwind car, first line, on boring machine, crank two sides bore centering benchmark, the mutual angle precision of three eccentric crankshafts requires strict, must on three cranks, entirely process centering benchmark, and on whirlwind car, adding man-hour each rotor journal all needs centering once.
In the processing of crankshaft eccentric axle journal, be the processing of centering benchmark or centering is all complicated process on lathe, poor to operator's product stability of having relatively high expectations.Not only be difficult to ensure card product quality but also time-consuming.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of simple in structure, can improve the machining accuracy of the rotor journal of three-throw crankshaft, reduces the three-throw crankshaft machining fixture of centering time.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises base, on base, be provided with upper press cover, between upper press cover and base, be provided with circular hole, it is characterized in that: in described circular hole, be provided with fixture body, the outline of described fixture body is the circle coordinating with described circular hole, is provided with regular hexagon hole in described fixture body; Described regular hexagon Kong center overlaps with the center of circle of the outline of fixture body.
As a kind of preferred version of the present utility model, described fixture body is combined by the first half and Lower Half, in the described first half, is upper three limits in regular hexagon hole, in described Lower Half, is lower three limits in regular hexagon hole.
Further preferred version, orthohexagonal upper three limits in the described first half, and orthohexagonal lower three limits in described Lower Half, Mei Tiaobian center all arranges connecting hole, and the described first half is connected with upper press cover by the connecting bolt in connecting hole; Described Lower Half is connected with base by the connecting bolt in connecting hole.
The beneficial effects of the utility model: 1, product quality is high: before the utility model is used, six sides outside crankshaft two end lengthening part bores of elder generation, when processing positive heart centre bore on boring machine, be processed into, utilize machine tool accuracy to improve positional precision and the indexing accuracy relative with center circle of crankshaft eccentric axle journal.
Because the utility model adopts six side's three positioning principles, the processing mode that need to repeatedly adjust rotor journal processing capacity than routine, can guarantee that rotor journal aligns the positional precision of axle neck (positional precision that rotor journal aligns axle neck mutually is determined by six side's machining accuracies) mutually, has increased substantially product quality.
2, easy to use, efficiency is high: due to of the present utility model simple in structure, convenient mounting and clamping on lathe, can take rapidly six sides as benchmark machining crankshafts rotor journal, therefore having solved conventional method needs repeatedly repeatedly to adjust the problem of centering, has greatly improved production efficiency.
