Abstract
The utility model discloses a rotating arm type automobile differential shell sphere cutter, comprising a cutter body. A Mohs cone is arranged at the rear end of the cutter body, the front end of the cutter body is rotatably connected with a positioning sleeve through a bearing, the positioning sleeve is matched with the inner end surface and an inner hole of an automobile differential shell, a fan-shaped groove is formed in the cylindrical surface at the front end of the cutter body, the inner end of the fan-shaped groove is arc-shaped, the arc is in interference fit with the inner end of a rotating arm, a centering shaft is arranged at the axis of the inner end of the rotating arm, the outer end of the rotating arm is connected with a cutter, the distance from the center of the centering shaft to the tip of the cutting tool is equal to that from the center of the centering shaft to the sphere center of the automobile differential shell, and the outer end of the rotating arm is connected with the front end of a pull rod. The cutter is pushed by the pull rod to do circular arc motion, and thus the spherical shape of the automobile differential shell can be processed. After the processing, the cutter can be recovered to the original position under the action of a spring, so that the next working cycle is facilitated, and the precision and the efficiency are high.
Description
Technical field:
The utility model relates to a kind of vehicle differential shell process tool, particularly relates to a kind of pivoted arm vehicle differential shell button tool.

Along with economic sustainable development, people's living standard is improved fast, progressively soaring to the demand of automobile, and how improving the production capacity of automobile and the production cost of reduction automobile is the major issue that car manufactures need to be considered.The traditional method of the poor shell sphere of processing automobile is to adopt forming tool, namely according to the concrete size of vehicle differential shell, grinds the spherical tool of a shaping, and this kind method has the following disadvantages: add roughness in man-hour, size and precision and all be difficult to guarantee and inefficiency.
The utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of reasonable in design, accurate positioning, the pivoted arm vehicle differential shell button tool that easy to use and production efficiency is high are provided.
The technical solution of the utility model is: a kind of pivoted arm vehicle differential shell button tool, contain cutter hub, described cutter hub rear end is provided with the Mohs cone, described cutter hub front end is connected with the positioning sleeve rotary type by bearing, described positioning sleeve matches with inner face and the endoporus of vehicle differential shell, and the length of described positioning sleeve equals the distance of vehicle differential shell inner face to the centre of sphere; On described cutter hub nose circle cylinder, be provided with a fan groove, the inner of described fan groove is circular arc, the axial line of described circular arc intersects with described cutter hub axial line and is mutually vertical, the inner interference fit of described circular arc and turning arm, and the inner axle center of described turning arm is provided with centration axis, the outer end of described turning arm is connected with cutter, the center of described centration axis equals the distance of the vehicle differential shell centre of sphere to the distance of the point of a knife of cutter, the outer end of described turning arm is connected with the front end of pull bar.
The front end of described pull bar and the outer end of described turning arm are hinged fixing, and described cutter hub rear portion is provided with support, and described pull bar rear portion is from passing the through hole on described support.Described through hole is strip hole.The rearward end of described pull bar is provided with nut, is set with spring on the described pull bar between described nut and support.
The beneficial effects of the utility model are:
1, the utility model cutter is done circular motion under the promotion of pull bar, thereby can process vehicle differential shell spherical shape, and after machining, cutter sets back under spring action, is convenient to carry out operation cycle next time, and its precision is high and efficiency is high.
2, the utility model positioning sleeve coordinates with poor shell inner face and endoporus, accurate positioning, and positioning sleeve is connected by bearing with the cutter hub front end in addition, rotates flexibly, is convenient to cutter turning processing.
3, the utility model pull bar and turning arm lower end are hinged, and turning arm upper end and cutter hub be by Cylindrical Surfaces Contact, and the rectilinear motion of pull bar can rotate by the driven rotary arm, is convenient to cutter turning and goes out spherical shape.
4, the utility model cutter hub rear end is provided with the Mohs cone, be convenient to be connected with tail stock, and can also quick-replaceable, easy to use.
5, reasonable in design, the accurate positioning of the utility model, easy to use and production efficiency is high, and it is applied widely, is easy to promotion and implementation, has good economic benefit.
The accompanying drawing explanation:
Fig. 1 is the structural representation of pivoted arm vehicle differential shell button tool.
The specific embodiment:
Embodiment: referring to Fig. 1, in figure, 1-positioning sleeve, 2-bearing, 3-centration axis, 4-cutter hub, 5-turning arm, 6-Mohs cone, 7-nut, 8-spring, 9-support, 10-pull bar, 11-cutter.
Pivoted arm vehicle differential shell button tool contains cutter hub 4, cutter hub 4 rear ends are provided with Mohs cone 6, cutter hub 4 front ends are connected with positioning sleeve 1 rotary type by bearing 2, positioning sleeve 1 matches with inner face and the endoporus of vehicle differential shell, and the length of positioning sleeve 1 equals the distance of vehicle differential shell inner face to the centre of sphere; On cutter hub 4 nose circle cylinders, be provided with a fan groove, the inner of fan groove is circular arc, the axial line of circular arc intersects with cutter hub 4 axial lines and is mutually vertical, the inner interference fit of circular arc and turning arm 5, and, the inner axle center of turning arm 5 is provided with centration axis 3, the outer end of turning arm 5 is connected with cutter 11, the center of centration axis 3 equals the distance of the vehicle differential shell centre of sphere to the distance of the point of a knife of cutter 11, the outer end of the front end of pull bar 10 and turning arm 5 is hinged fixing, and cutter hub 4 rear portions are provided with support 9, pull bar 10 rear portions are from passing the through hole on support 9.
