Abstract
The utility model relates to a cam shaft milling end surface and drill centre hole locating fixture, belonging to the field of machining technology, and aiming at solving the problems of being more in production processes, low in production efficiency and labor-consuming in the prior art. The cam shaft milling end surface and drill centre hole locating fixture comprises two groups of cutters which are symmetrically arranged on a stand; two groups of mechanical arms are symmetrically arranged between the two groups of cutters; each mechanical arm comprises an upper clamp seat and a lower clamp seat which are arranged on a guide plate; a hydraulic cylinder is fixedly arranged at the upper end of the each upper clamp seat, and an upper chuck is arranged at the lower end of the each upper clamp seat; an upper chuck is arranged at the upper end of the each lower clamp seat; and a guide rail is arranged on the guide plate. The cam shaft milling end surface and drill centre hole locating fixture is reasonable in structural design; the chucks used for clamping a workpiece are controlled by a chuckhydraulic system; the operation process for clamping the workpiece is simple and convenient in automatic control; and a milling end surface and a center hole of the workpiece can be machined for once, so that the production processes of a cam shaft are simplified, the labor force is saved, and the processing equipment can be reduced.
Description
Technical field:
The utility model relates to the machining technique field, relates in particular to a kind of camshaft end face milling, drill centers positioning fixture.
Background technology:
Camshaft is parts in the piston engine.Its effect is the opening and closing action of control valve.Usually its rotating speed is very high, and need to bear very large moment of torsion, therefore very high in the requirement aspect intensity and the support to camshaft in the design, its material generally is Special Casting Iron, also has once in a while to adopt forging.Because the valve motion rule is related to power and the service performance of an engine, thus camshaft design in the design process of engine in occupation of consequence very.The main body of camshaft is a cylindrical barred body identical with cylinder group length.Upper surface cover has several cams, is used for driving valve.One end of camshaft is the bearing block strong point, and the other end is connected with driving wheel.
Camshaft Production processing is very high to the requirement of precision, and at present, the processing of camshaft end face milling and centre bore are processed as two procedures and finish, and production efficiency is low, and use process equipment and workman are many.
The utility model content:
Technical problem to be solved in the utility model is to provide a kind of camshaft end face milling reasonable in design, drill centers positioning fixture, can disposablely finish the processing of end face milling and centre bore, solution prior art production process is many, production efficiency is low, the problem that recruitment is many.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of camshaft end face milling, drill centers positioning fixture, it is characterized in that: comprise symmetrical rack-mounted two groups of cutters, be symmetrically arranged with two groups of manipulators between two groups of cutters, manipulator comprises upper holder and the lower holder that is installed on the guide plate, described upper holder upper end is fixed with hydraulic cylinder, chuck is installed in described upper holder lower end, and chuck is installed in described lower holder upper end.
Be provided with guide rail on the described guide plate, upper holder and lower holder can move up and down along guide rail, after camshaft is fixedly clamped by upper grip and lower chuck, can drive camshaft moves up, finish camshaft end face milling operation by cutter, after camshaft was finished end face milling, the drill bit in the middle of the milling cutter carried out centre bore processing.
Described cutter is the milling cutter of end face milling, is provided with drill bit in the middle of the milling cutter.
The utility model reasonable in design, the chuck of clamping workpiece passes through HYDRAULIC CONTROL SYSTEM, the clamping workpiece operating process is simple, be convenient to automation control, can disposablely finish end face milling and centre bore processing to workpiece, simplify the production process of camshaft, saved the labour, reduced process equipment.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with specifically illustrating and specific embodiment, further set forth the utility model, but be not to limit protection domain of the present utility model.
Please refer to Fig. 1, a kind of camshaft end face milling, the drill centers positioning fixture, comprise that symmetry is installed in two groups of cutters 9 on the frame 8, be symmetrically arranged with two groups of manipulators between two groups of cutters 9, manipulator comprises upper holder 3 and the lower holder 6 that is installed on the guide plate 2, upper holder 3 upper ends are fixed with hydraulic cylinder 10, chuck 4 is installed in upper holder 3 lower ends, chuck 5 is installed in lower holder 6 upper ends, be provided with guide rail 1 on the guide plate 2, upper holder 3 and lower holder 6 can move up and down along guide rail 1, after camshaft 7 is fixedly clamped by upper grip 4 and lower chuck 6, manipulator can drive camshaft 7 and move up, finish camshaft end face milling operation by cutter 9, after camshaft 7 was finished end face milling, the drill bit in the middle of the milling cutter carried out centre bore processing, cutter is the milling cutter of end face milling, is provided with drill bit in the middle of the milling cutter.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.It only is the specific embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
