Abstract

The utility model provides a cam shaft oil drilling hole clamp, which relates to the technical field of machining and can solve the problem that the traditional clamp cannot realize the perfect fixation on the cam shaft oil drilling hole processing. The cam shaft oil drilling hole clamp comprises a vertical plate, wherein one side of the vertical plate is provided with a guide groove, one side of the vertical plate provided with the guide groove is provided with a clamping mechanism, a lower fixing seat is fixedly arranged under the clamping mechanism, the upper end of the lower fixing seat is provided with a top head, the clamping mechanism comprises a center shaft and a position limiting block fixedly arranged on the vertical plate, the center shaft passes through the middle part of a fixing rod, a screwing handle is arranged on the center shaft passing through the fixing rod, the left end of the fixing rod is fixedly provided with a support rod, and the position limiting block is a V-shaped position limiting block. The cam shaft oil drilling hole clamp has the advantages that the structure is simple, the design is reasonable, the manufacture cost is lower, the installation and the clamping of a cam shaft are convenient, the work efficiency is high, the upper end of the cam shaft is fixed through the V-shaped position limiting block, and the fixation effect is good.

Description

Camshaft bores oil hole clamp

Technical field:

The utility model relates to the machining technique field, relates in particular to a kind of camshaft and bores oil hole clamp.

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, at present, camshaft is being bored in the machining of oil hole process, because camshaft is elongated rod member, and be shaped with a lot of variform cams on the rod member, so that traditional anchor clamps can't well be fixed camshaft.In the prior art, also there is not a kind of special fixture that bores oilhole for camshaft.Therefore a kind of in the urgent need to designing, simple in structure, easy to use, the anchor clamps of good fixing effect.

The utility model content:

Technical problem to be solved in the utility model is to provide a kind of camshaft simple in structure, easy to use to bore oil hole clamp, can't bore machining of oil hole to camshaft with the solution conventional brace and carry out fine fixing problem.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of camshaft bores oil hole clamp, and it is characterized in that: comprise that a side is provided with the riser of gathering sill, gathering sill one side of riser is equipped with clamp mechanism, and the clamp mechanism below is fixed with lower fixed seat, and the lower fixed seat upper end arranges the top.

Described clamp mechanism comprises limited block and the central shaft that is fixed on the riser, and central shaft passes the middle part of fixed bar, passes to be provided with on the central shaft of fixed bar to screw handle, and described fixed bar left end is fixed with support bar.

Described limited block is the V-type limited block.

During the camshaft clamping, the camshaft lower end is withstood on the top, the upper end is leaned in limited block, with being pressed in the camshaft outside after the fixed bar rotation, will screw handle and screw, and can be fixed camshaft.

The utility model is simple in structure, and is reasonable in design, and manufacturing cost is lower, the camshaft convenient mounting and clamping, and high efficiency, the camshaft upper end is fixed good positioning effect by the V-type limited block.

Description of drawings:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of clamp mechanism.

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, Fig. 2, a kind of camshaft bores oil hole clamp, comprise that a side is provided with the riser 3 of gathering sill 1, gathering sill one side of riser 3 is equipped with clamp mechanism 2, clamp mechanism 2 belows are fixed with lower fixed seat 5, lower fixed seat 5 upper ends arrange top 4, clamp mechanism 2 comprises limited block 21 and the central shaft 23 that is fixed on the riser 3, central shaft 23 passes the middle part of fixed bar 25, pass to be provided with on the central shaft 23 of fixed bar 25 and screw handle 24, fixed bar 25 left ends are fixed with support bar 22, and limited block 21 is the V-type limited block.

During camshaft 6 clamping, camshaft 6 lower ends are withstood on the top 4, the upper end is leaned in limited block 21, with being pressed in camshaft 6 outsides after fixed bar 25 rotations, will screw handle 24 and screw, and can be fixed camshaft 6.

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.
